When the economic situation warrants medicine dictionary prescription drugs cheap 8mg coversyl otc, the parents should be guided to the appropriate source of community-sponsored medical care. As used in this portion of these regulations, these terms shall mean: (1) "Contact" means a person exposed to an infected person, animal, or contaminated environment which might provide an opportunity to acquire the infection. Schools shall: (1) Notify the local health department of cases, suspected cases, outbreaks, and suspected outbreaks of disease that may be associated with the school. Each local health jurisdiction, as well as the department, maintains after-hours emergency phone contacts for this purpose. A party sending a report by secure facsimile copy or secure electronic transmission during normal business hours must confirm immediate receipt by a live person. A party sending a report outside of normal public health business hours must use the after hours emergency phone contact for the appropriate jurisdiction. The district will require that the parents or guardian complete a medical history form at the beginning of each school year. The nurse or school physician may use such reports to advise the parent of the need for further medical attention and to plan for potential health problems in school. The principal will cooperate with the local health officials in the investigation of the source of the disease. The fact that a student has been tested for a sexually transmitted disease, the test result, any information relating to the diagnosis or treatment of a sexually transmitted disease, and any information regarding drug or alcohol treatment for a student must be kept strictly confidential. The local health officer is the primary resource in the identification and control of infectious disease in community and school. The local health officer, in consultation with the superintendent can take whatever action deemed necessary to control or eliminate the spread of disease, including closing a school. Localized rash cases diagnosed as unrelated to a contagious disease, such as diaper rash, poison oak, etc. In addition to rash illnesses, any unusual cluster of infectious disease must be reported to the school nurse. Follow-up of suspected communicable disease cases should be carried out in order to determine any action necessary to prevent the spread of the disease to additional children. Reporting At Building Level A student with a diagnosed reportable condition will be reported by the school principal or designee to the local health officer (or state health officer if local health officer is not available) as per schedule. Call the parent, guardian or emergency phone number to advise him/her of the signs and symptoms; 2. Keep the student isolated but observed until the parent or guardian arrives; and 4. Disposable sheath covers will be discarded in a lined trash container that is secured and disposed of daily. Body fluids of all persons should be considered to contain potentially infectious agents (germs). General cleaning procedures will include use of a 10 percent bleach solution to kill norovirus and C. To be effective, a release must be signed and dated, must specify to whom the release may be made and the time period for which the release is effective. Students thirteen and older must authorize disclosure regarding drug or alcohol treatment or mental health treatment. Students of any age must authorize disclosure regarding family planning or abortion. A general authorization for the release of medical or other information is not sufficient for this purpose. These rules and regulations are established as minimum environmental standards for educational facilities and do not necessarily reflect optimum standards for facility planning and operation. The following definitions shall apply in the interpretation and the enforcement of these rules and regulations: (1) "School" Shall mean any publicly financed or private or parochial school or facility used for the purpose of school instruction, from the kindergarten through twelfth grade. This definition does not include a private residence in which parents teach their own natural or legally adopted children. Ceiling height shall be the clear vertical distance from the finished floor to the finished ceiling. Exterior sun control is not required if air conditioning is provided, or special glass installed having a total solar energy transmission factor less than 60 percent. However, local code requirements shall prevail, when these requirements are more stringent or in excess of the state building code. All sewage and waste water from a school shall be drained to a sewerage disposal system which is approved by the jurisdictional agency. Only closed vehicles shall be used in transporting foods from central kitchens to other schools. The board of health may, at its discretion, exempt a school from complying with parts of these regulations when it has been found after thorough investigation and consideration that such exemption may be made in an individual case without placing the health or safety of the students or staff of the school in danger and that strict enforcement of the regulation would create an undue hardship upon the school. No distinction is made between body fluids from students with a known disease or those from students without symptoms or with an undiagnosed or unreported disease. Standard precautions include a group of infection prevention practices that apply to all persons, regardless of suspected or confirmed infection status, in any setting with delivery of healthcare, including first aid. These precautions address hand hygiene, use of personal protective equipment depending on the anticipated exposure, and safe injection practices. Also, equipment or items in the environment likely to have been contaminated with infectious body fluids must be handled in a manner to prevent transmission of infectious agents. Respiratory hygiene has become a standard practice in school and community influenza control plans. This includes use of masks when providing healthcare to a person with a potential respiratory infection as well as everybody covering coughs and sneezes. Enough sanitizer should be used to wet the hands for at least 15 seconds or longer if indicated by the manufacturer. All other personnel should have access to first aid supplies, which includes gloves. However, utility gloves must be discarded if they are cracked, peeling, torn, punctured, or exhibit other signs of deterioration, or when their ability to function as a barrier is compromised. Staff with sores or cuts on their hands (non-intact skin) having contact with blood or body fluids should always double glove if lesions are extensive. Cleanup must be accomplished using mechanical means such as a brush and dustpan, tongs, or forceps, by staff wearing appropriate protective gloves. The secondary container must be closable, constructed to contain all contents, and prevent leakage during handling, storage, transport, or shipping. Sanitizers reduce the level of microorganisms to levels considered safe for general purposes. Many of the active ingredients in disinfectant products are skin, eye, and respiratory irritants. Manufacturer label instructions must be followed, including those for personal protective equipment. A 1:10 bleach solution of household (5-6 percent) bleach with a one minute wet time is necessary to kill noroviruses. While the vegetative forms of bacteria are killed by a range of disinfectants, bacterial spores are not. Never soak wipe cloths or mops in a class of disinfectant that is different from the disinfectant you were using on the cloth or mop to clean a surface or item. Never use disinfectant or pesticide foggers in schools or spray disinfectants into the air. They are to be used on hard surfaces and should be breathed as little as possible. There should not be exposure of open skin or mucous membranes to blood or body fluids being cleaned. The dry material is applied to the area, left for a few minutes to absorb the fluid. A solution of six percent sodium hypochlorite (unscented household bleach) diluted 1:10 with water may also be used.

The most serious adverse reaction to allergy skin testing or immuno therapy is medications known to cause tinnitus purchase coversyl 8mg line. You cannot assume that right is right and lef is lef when the flm is positioned so you can read the name. Remember this very basic principle: When two structures of the same radiographic density are adjacent, the border between them is obscured. For example, if you cannot see the right heart border on a posterior-anterior chest x-ray, the lung next to the heart (right middle lobe) has the same density (water density) as the heart. Likewise, pus or fuid in the sinus has the same den sity as thickening of the sinus mucosa. The relative density of bone and other structures can be manipulated by the scan reader as either bone win dow (demonstrates clear bone detail) or sof tissue window (bones too bright, sof tissue easily visualized). Systematically reviewing any imaging study in sequence is critical to recognizing subtle abnormalities. Although the novice viewer routinely examines the maxillary sinuses frst, you should carefully evaluate the orbits, orbital walls, skull base, maxillary alveolus, nasal septum, and sinuses in order. The surgical correction of Abnormalities include fuid, mucosal nasal obstruction in this patient would thickening, bony fractures, cysts, and require partial middle turbinectomy, as well as correction of the deviated nasal septum. In most instances, sinusitis is manifested by loss of aeration of multiple sinuses, usually involving both sides. This is visible as water density, which may be swelling of the muco sa, polyps, fuid, or pus. Clouding of a single sinus (unilateral disease) sug gests an unusual cause, such as a tumor. Moreover, it is not necessary in the evaluation of all patients, since the history and physical, particularly nasal endoscopy, will ofen identify the source of the pathology. Medical therapy, consisting of antibiotics, decongestants, and topical steroids can be initiated based on clinical criteria. It should be noted that all patients with nasal polyposis have chronic sinus itis, typically involving all sinuses. Unilateral nasal polyposis associated with unilateral sinusitis suggests tumor (most commonly inverted papil loma, a benign growth caused by human papilloma virus). Remember: The best way to learn to look at any x-ray or imaging study is to carefully and systematically examine as many as possible. When two structures of the same radiographic density are adjacent to 77 each other, the border between them becomes . Healthcare professionals always wonder whether a patient should have a cricothyrotomy or intubation. One way to think about this decision is to review a checklist of ways to secure the airway. Do not forget that the most common cause of airway obstruction in a patient with an altered level of consciousness is the tongue falling back into the throat. This can be treat ed by a jaw lif maneuver, an oral airway, or a long nasal airway. Also consider the possibility of a foreign body (dentures in adults; balloons, small toys, food, etc. If the cause of airway obstruction is not so simple, however, the quickest and easiest method of securing the airway is endotracheal intubation through the mouth. This requires placing a laryngoscope down through the mouth to the larynx (direct laryngoscopy) and lifing up. The vocal cords are seen, and then the tube is placed between the vocal cords and into the trachea. Direct laryngoscopy requires movement of the neck, and if the neck is already broken, it can possibly move during the proce dure and compress the spinal cord, causing paraplegia, quadriplegia, or death. Terefore, oral endotracheal intubation is not to be performed if a patient has either a known C-spine fracture or a likelihood of having a C-spine fracture that has not been ruled out by a lateral neck flm. The second reason you might not be able to perform oral intubation is massive facial and neck trauma with distortion of land marks and bleeding. This patient might have had a lateral C-spine flm that showed no C-spine fracture, but at direct laryngoscopy, all you can see is blood and disrupted tissue. You would perform a crico thyrotomy, unless there is concern over a 80 fractured larynx (widened thyroid car tilage, subcutaneous air [crepitus], neck bruising, hoarseness, coughing up blood), in which case, a tracheotomy is Figure 12. In this case, an endotracheal tube is passed through the nose down into the hypopharynx, guided by a fberoptic endoscope placed through the endotracheal tube. With the endoscope, you can see when the tube approaches and is advanced into the larynx. You must wait until just afer an expiration, because the ideal time to push the endoscope through is when the patient breaths in, opening the vocal cords. Once the endoscope is in the trachea, the tube is passed over the scope, and the endoscope is then removed. The advantage of the fberoptic nasotracheal intubation technique is that the neck is not manipulated at all, so it is still a viable option, even if a C-spine fracture has not been ruled out. Fiberoptic nasotracheal intubation is best performed on an awake patient who is able to sit upright. This technique is not feasible if visualization is obscured by secretions, blood, or swelling. Also, if there is a severe midface injury with possible cribriform plate fracture, passage of a nasogastric or blind nasotracheal tube is contraindicated because the tube may pass into the brain. You cannot perform an oral intubation (perhaps because the lateral C-spine flm shows a broken neck), and you cannot perform a nasotracheal intubation (perhaps because the patient has profuse oral bleeding). The exception to this is a patient with severe laryngeal trauma, where mask ventilation or intubation could worsen the situation. In an 81 emergency, cricothyrotomy may be chosen over tracheotomy, because it is quicker and is accomplished through the relatively thin and more superf cial cricothyroid membrane. Other Aspects of Maxillofacial Trauma Management Anyone who has sustained enough trauma to break a facial bone should be assumed to have a C-spine fracture until this is ruled out. Rule #1 in maxillofacial trauma management is secure the Airway, Breathing, and Circulation. Check that the facial nerve works on both sides, since a complication of temporal bone fracture may be facial nerve paral ysis (an otolaryngologist should Figure 12. This may be due orbital rims to ascertain whether to soft tissue trauma only, or it may be a or not a malar (tripod) fracture manifestation of an underlying fracture. Make sure the patient is not expe riencing double vision, which may occur when an orbital blowout fracture happens and the inferior rectus or medial rectus becomes entrapped. Make sure that there is no infraor bital nerve hypesthesia, 82 which can also occur with a blowout fracture or a tripod fracture. This fracture often results in entrapment 14 days afer the fracture, if of the inferior rectus muscle and limitation of upward they cause a cosmetic defor gaze. It is easier to do when there is less swelling, and usually the swelling goes down by fve to seven days. This can result in septal necro sis, with subsequent perforation due to either a loss of nutrition from the perichondrium or a secondary infection of the hematoma, generally with Staphylococcus aureus. Tese conditions are treated by incision, drainage, and packing to ensure that the blood and bacteria do not reaccumulate. Radiographs are not particularly helpful in cases of a broken nose, because old fractures cannot be distinguished from acute ones. Uncomplicated nasal fractures are treated with antibiotics, pain medicine, a decongestant nasal spray, and a referral for reduction within three to fve days.

Because traditional procedures use high levels of heat to remove tonsils symptoms xanax abuse discount 8mg coversyl mastercard, damage to surrounding healthy tissue is common. Coblation does not remove the tonsils by heating or burning, leaving the healthy tissue surrounding the tonsils intact. This will help thin secretions in the throat, which will decrease pain and make swallowing easier. This happens because the nerves that control sensations in the throat are connected to the nerves in the ears. This pain usually lasts for only a few days, and can be controlled by applying a heating pad or a warm compress to the ears for 10-20 minutes as needed. To prevent bleeding, avoid coughing, nose blowing, clearing the throat and spitting. While you are healing from tonsil surgery, white patches may appear in the throat. Note: If your child vomits after drinking red liquids, the vomit will be the same color. Avoid citrus fruits and juices such as orange juice and lemonade, as they may sting the throat.

For example symptoms stomach flu generic 8mg coversyl with mastercard, a woman may experience discomfort or pain before or during menstruation: those assisting her may feel that her limited communication skills may prevent her from communicating this discomfort. Providing information is an important part of effective preparation for menstruation. These messages and symbols may also be used by older women needing explanations and prompts for menstrual management. Think about trying some of the following ideas: Keep a menstrual chart (see Menstrual Charting). Communication and Management of Physical Changes and/or Discomfort the possibility that a woman who has high support needs may experience pain or discomfort and be unable to communicate this, can cause serious concern to those assisting her. Even for those women least able to communicate intentionally, it may be possible to evaluate their comfort, as well as the effectiveness of strategies for easing discomfort (see Tables one and two). By using a structure approach to communication, people assisting this woman can develop an awareness of messages she sends, and gauge the effectiveness of different management approaches for her. Most menstrual management teaching approaches identify relevant behaviour and abilities of young women before teaching begins. If appropriate behaviours are occurring, an understanding of just how often, and in what circumstances the behaviour occur, can be developed through observation and recording. Some women may not feel comfortable with the idea of talking about periods, or allowing their daughters to observe their menstrual self-care. Consistency in the way pads are disposed of in different environments is recommended where possible. Ideas which some people have used in these situations include: Basic explanation of what is appropriate and why this is so. Popovich (1981) describes a range of reinforcement procedures and gives examples of how to use them. Try to find pads and clothing which she feels comfortable wearing (this may needs some trialling). If the young woman is wearing menstrual pads, could they be thinner, or contoured For example, for a woman who currently assists at meal times, or while using the toilet, try rubber or self inking stamp and a large calendar; for a woman with very poor vision, a method which relies more on touch and less on visual information may be more helpful (eg. It is likely that for each woman there will only be 3-4 types of information recorded. If unsure, it is suggested that people assisting the young woman use the Estimation of Menstrual Flow chart (at the end of this booklet) for several months. Many women with high support needs are not able to assist with pen and paper style recording. For example, record elsewhere that kind of behaviour changes, type of flow, or method of disposal, applies to each individual (For details of stamp suppliers, see Resources). It also allows the woman to use her sense of touch to find charting symbols, and to locate where they should go. Choices should be based on the individual needs of each woman, including her preference and learning style. For women not using incontinence pads: Ensure the young woman has firm-fitting briefs (full briefs are better than bikini styles); close fit will assist her pads to remain in place, and will minimise the occurrence of menstrual odour. Physical changes may include fluid retention, breast tenderness, headaches, acne, and general aches and pains. It has been found that physical discomfort and negative mood changes are often more noticeable during times of life stress or personal disruption. Try to ensure that the woman has opportunities to express her feelings, and to receive comfort and sympathy. People assisting these young women should try to ensure that they too receive support, if they feel it is needed. The young woman may need the opportunity to cry, laugh or scream; this may help her to avoid taking out frustrations on others. Their precise effects and usefulness do not appear to have been comprehensively documented. It can be accompanied by nausea and vomiting, diarrhoea, headache and occasional shakiness. For Planning Approaches to Management of Discomfort during Menstruation, see Guidelines. Drinking plenty of fluids, and increasing the moisture content of the air at home, may help to reduce discomfort associated with vaginal dryness. Avoid the use of vaginal douches and sprays, and coloured or perfumed powders or soaps. More mature women will benefit from regular, moderate, weight-bearing exercise, such as walking. It has been noted that oestrogen occurs in other body tissues, as well as being produced by the ovaries, so that ovarian function does not result in a total lack of oestrogen for post-menopausal women. The High Court of Australia recommended that the Family Court of Australia is appropriate for such applications. Queensland Advocacy Incorporated, Position statement relating the sterilisation of people with disability. Some people suggest that menstrual regulation of suppression can be used on a short term basis to enable young women to become more emotionally mature, and perhaps to develop more skills.

No one knew of the existence of the adrenal glands until Bartholomeo Eustachius (for whom the eustachian tube is named) described their anatomy in 1563 adhd medications 6 year old effective coversyl 4 mg, but there may have been a hint from a much older source. The Hebrew Bible, in Exodus and Leviticus, describes in detail the rituals of animal sacrifice. Some tissues were specified for ritual burning; eating them was strictly forbidden. The fat above the kidneys is unique for its contents, because buried within it are the adrenal glands, which store the powerful adrenocortical hormones, cortisol, aldosterone, and adrenal androgens, and the even more powerful adrenomedullary hormone, adrenaline. Depending on the efficiency of metabolic breakdown of these chemicals in the gut, eating adrenal gland tissue could result in entry of one or more of these physiologically active compounds into the bloodstream. Ingestion of adrenal gland tissue repeatedly by the priests over a long period could have made them ill or killed them. Cannon taught that the sympathetic nervous system and adrenal gland act as a functional unit in emergencies. The nerves were traced to their source in the 48 Principles of Autonomic Medicine v. At about the same time, other investigators noted the indirect, reflexive cardiovascular effects of stimulating neural pathways traveling to the brain. In 1836, Sir Astley Cooper showed that occluding the common carotid arteries increased blood pressure and heart rate, and in 1900 Siciliano proposed that a signal to the brain comes from the region of where the carotid artery splits into the internal and external carotid arteries. Heymans) studied reflexive regulation of breathing based on afferent input to the respiratory center in the brainstem from the carotid sinus region. The experiments exploited an extraordinary preparation developed by the senior Heymans that made it possible to keep alive the completely isolated head of a dog by perfusion of blood from another dog, while the body was also kept alive with the help of artificial respiration. This meant that the only communication between the head and the rest of the body was provided by the nerves. Heymans showed that when the lungs expand, inspiration reflexively ceases, and when the lungs are collapsed, inspiration reflexively is stimulated (the Hering-Breuer reflex). Heymans also demonstrated that high blood pressure at the carotid sinus reflexively relaxes blood vessels and decreases the heart rate (the arterial baroreflex). He also proposed that the carotid sinus baroreflex modifies adrenomedullary secretion reflexively. Corneille Heymans received a Nobel Prize in 1938 for his studies of chemoreflexes regulating breathing and baroreflexes regulating blood pressure. Heymans therefore described what can be depicted by a two by-two table, in which increasing carbon dioxide tension or decreasing oxygen tension in the carotid arterial blood not only reflexively increases respiration, via chemoreceptors in the carotid body, but also constricts blood vessels and increases heart rate; and increasing carotid arterial pressure not only relaxes blood vessels and slows heart rate but also decreases respiration, via carotid sinus stretching and baroreceptor stimulation. For this work Heymans received a Nobel Prize in 50 Principles of Autonomic Medicine v. Cannon studied not only peripheral autonomic systems but also sites in the brain that regulate them. In the 1920s he noted that removal of the cerebral cortexes evoked rage behavior, accompanied by high blood glucose levels; decorticated adrenalectomized animals exhibited the same behavior, but without hyperglycemia. These findings fit with cortical restraint of primitive emotional behaviors and of emotion associated adrenaline release. Bard directed the Department of Physiology at Johns Hopkins for 31 years and was an Emeritus Professor when I was a medical student there. In the 1920s to 1930s the Swiss physiologist Walter Rudolf Hess focused on the functional organization of the hypothalamus with respect to the regulation of parasympathetic and sympathetic outflows. In contrast, stimulation of other sites evoked slow heart rate, salivation, pupillary constriction, vomiting, urination, and defecation, consistent with generalized parasympathetic activation. The sympathetic-ergotropic and parasympathetic-trophotropic areas operated as if they were in a dynamic state of equilibrium. Hess received a Nobel Prize in 1949 for his research on regulation of autonomic outflows from the hypothalamus. In 1954 Marthe Vogt noted large regional differences in concentrations of norepinephrine (still termed 52 Principles of Autonomic Medicine v. This heterogeneity could not be explained by norepinephrine in blood vessel walls and suggested the existence of norepinephrine as a neurotransmitter in particular brain areas. Annica Dahlstrom and Kjell Fuxe subsequently described catecholamine pathways and centers that were distinct from traditional neuroanatomic tracts and nuclei. First, most interoceptive inputs to the brain were found to terminate in a specific cluster of cells in the dorsomedial 53 Principles of Autonomic Medicine v. Adding to the rich diversity, Tomas Hokfelt subsequently reported evidence for co-storage of peptides with catecholamines in brainstem neurons, and Geoffrey Burnstock introduced the concept of purinergic autonomic nerves. Discoveries based on catecholamine research relate directly to regulation and dysregulation of the inner world by the autonomic nervous system and development of several novel, successful, rational treatments for major diseases. This section presents some of these discoveries together, to introduce ideas that receive more attention in future sections and to affirm the continuing importance of catecholamine systems in science and medicine. In the mid-1940s, Ulf Svante von Euler identified the neurotransmitter of the sympathetic nerves in mammals as not adrenaline, which Loewi and Cannon had proposed, but 55 Principles of Autonomic Medicine v. After release of norepinephrine from sympathetic nerves, the norepinephrine undergoes inactivation mainly by a conservative recycling process, in which sympathetic nerves take up norepinephrine from the fluid bathing the cells-a process called uptake-1. Once back inside the nerve cells, most of the norepinephrine undergoes uptake back into storage vesicles. Julius Axelrod (Nobel Prize, 1970) discovered neuronal reuptake as a route of catecholamine inactivation. For the development of beta-adrenoceptor blockers, Sir James Black shared a Nobel Prize in 1988. Discoveries related to the mechanisms determining cellular 57 Principles of Autonomic Medicine v. For the discovery of phosphorylation as a key step in the activation or inactivation of cellular processes, Edmond H. Arvid Carlsson (Nobel Prize, 2000) discovered that dopamine is a neurotransmitter in the brain. Until about the 1950s, dopamine had been assumed not to have any specific function in the body beyond serving as a chemical intermediary in the production of adrenaline and norepinephrine. Carlsson discovered that dopamine in the brain 58 Principles of Autonomic Medicine v. Carlsson also demonstrated that effective drugs to treat schizophrenia work by blocking dopamine receptors in the brain. Greengard discovered that communication between nerve cells mediated by catecholamines takes place by a relatively slow, diffuse process, called slow synaptic transmission. This process probably underlies phenomena such as mood and vigilance and also modulates fast synaptic transmission, which is involved with rapid phenomena such as speech, movement, and sensation.

Introduction Peripartum or obstetric hysterectomy is the removal of the corpus uteri alone or with the cervix at the time of a cesarean section, or shortly after a vaginal delivery. The removal of the uterus at cesarean section is referred to as cesarean hysterectomy while the removal after vaginal birth is called postpartum hysterectomy [1]. Peripartum hysterectomy is reserved for situations in which severe obstetric hemorrhage fails to respond to conservative treatment [2, 3]. It is therefore unplanned and must be performed expeditiously usually in patients that are generally in less than ideal condition to withstand anesthesia and trauma of surgery. It has been described as one of the riskiest and most dramatic operations in modern obstetrics[2, 4, 5]. Evolution of peripartum hysterectomy Cesarean hysterectomy was originally proposed in 1768 by Joseph Cavallini in animal experiments[6]. The first documented hysterectomy on a patient at Caesarean section was performed in United States by Horatio Storer in 1869. Although the uterus was removed successfully, the patient died in 68 hours after surgery[6, 7, 8]. James Blundell in 1823 based his opinion approving post-cesarean hysterectomy on work done with rabbits. His patient was a primiparous dwarf, Julia Cavallani, who was 25 years of age and was only 144cm in height. The stump was brought out through the abdominal wound which was closed with sutures of silver wire[7]. Notable among these modifications were those of Godson in 1884 and Lawson tait in 1890[7, 8] 94 Hysterectomy Originally the indications for periparturm hysterectomy included uterine sepsis (amnionitis) after prolonged labour, atonia uteri or uncontrollable hemorrhage from placenta site, cancer of the cervix, extensive atresia of the vagina, preventing discharge of lochia, cases of ruptured uterus where suturing would be unsafe, uterine fibroids and tuberculosis[7]. By the 1950s it was carried out as elective procedure for indications such as sterilization, uterine fibroids and cervical dysplasia. By the 1970s elective cesarean hysterectomy for such procedures fell into disrepute due to the association of the procedure with excessive blood loss and urological injury. Moreover, with the introduction of laparoscopic procedures in sterilization, the indications for peripartum hysterectomy have become almost exclusively emergent occurring complications [7, 8]. Incidence and risk factors the reported incidence of emergency peripartum hysterectomy varies between 0. In general, the average incidence is put at 1 in 1000 deliveries, the higher incidence is being reported from the developing world while developed countries generally report lower rates[5, 9]. The high incidence of peripatum hysterectomy in the developing world may be due to her phenomenon of unbooked emergencies and the earlier recourse to hysterectomy due to the lack of adequate cross matched blood and other blood products which limit the time available for examining the effectiveness of other conservative procedures [5, 40]. Moreover, certain modern conservative procedures involving interventional radiology are not practicable in most developing world settings due to lack of human and material resources involved[5]. There is significant association between peripartum hysterectomy and previous caesarean section and placenta previa[10, 11, 12]. The combination of prior caesarean section and placenta previa is said to be an ominous risk factor for the life threatening hemorrhage and peripartum hysterectomy [11, 12, 25, 30]. Owing to the rising cesarean section rate world wide and the concomitant rise in placenta previa and placenta previa accreta, the incidence of emergency peripartum hysterectomy is rising in many countries[5, 11, 12, 25]. Compared to vaginal delivery, emergency peripartum and abdominal delivery are strongly associated [1, 19]. The association of peripartum hysterectomy with abdominal delivery may be related to its indications such as placenta previa and previous caesarean sections[1, 5, 12, 13]. It may also be related to the fact that the uterus is readily available for removal in abdominal delivery[19]. It has also been reported that the multiple pregnancy has a six fold increased risk of emergency peripartum hysterectomy[12, 17]. Multiple pregnancies are associated with higher rates of premature labour requiring tocolysis and uterine distension with greater total fetal weight at delivery[12]. The increase in multiple pregnancy rates associated with assisted reproductive technology may provide a further contribution to rising peripartum hysterectomy rates. Peripartum Hysterectomy 95 Other reported risk factors for peripartum hysterectomy include unbooked status, retained placenta, previous endometrial curettage, abruptio placentae and thrombocytopenia [5, 14, 15, 18]. Indications the most common indication for peripartum hysterectomy is hemorrhage but the underlying causes vary from series to series. In the developing world, preventable factor such as uterine rupture or uterine atony is the most common indication for peripartum hysterectomy[5, 9, 13, 14, 22]. The common causes of uterine rupture in this part of the world include prolonged obstructed labour, rupture of a previous caesarean scar, injudicious use of oxytocics and trauma from instruments or manual removal. If the rupture is extensive and hemorrhage cannot be controlled by uterine repair, then hysterectomy may become necessary [22]. Non-utilization or unavailability of modern potent oxytocic agents may predispose the at risk women to uterine atony and peripartum hysterectomy. There are however cases in which the uterus is not responsive to such uterotonic agents. Older studies from the developed countries also showed uterine rupture or uterine atony as the most common indication for peripartum hysterectomy. In these countries uterine rupture has been reduced to a rarity by large scale utilization of modern obstetric care while uterine atony has also been reduced by use of potent uterotonic agents[16, 23, 24, 25]. With rising caesarean section rate and marked reduction in the incidence of uterine rupture and atony, recent studies from the developed world have shown that placenta accreta has replaced uterine rupture and atony as the most common indication for emergency peripartum hysterectomy [24, 25, 26, 27, 29]. This is due to the rising incidence of placenta previa or accreta associated with the increasing number of women with previous caesarean section [20, 21, 28, 30, 31, 32, 33]. In this era of modern potent antibiotic, sepsis is not a common indicaton for peripartum hysterectomy. It may however be necessary in cases with extensive uterine sepsis with myometrial abcess formation, in which antibiotic fails to control the infection [12]. If an antenatal diagnosis or strong suspicion of placenta accreta is made, the patient should therefore be counseled about the likelihood of peripartum hysterectomy[28, 31]. In addition a senior obstetrician with vast experience in obstetric hysterectomy should be present at surgery. With the rising caesarean section rate also in the developing countries, placenta accreta is becoming superimposed on the prevalent preventable indication such as uterine rupture and atony[5, 14].

It may be peripheral in origin (retinal disease; opacities within cornea, lens, vitreous); or central (lesions anywhere from optic nerve to occipitotemporal region). Cross Reference Photophobia Decerebrate Rigidity Decerebrate rigidity is a posture observed in comatose patients in which there is extension and pronation of the upper extremities, extension of the legs, and plantar exion of the feet (= extensor posturing), which is taken to be an exagger ation of the normal standing position. Painful stimuli may induce opisthotonos, hyperextension, and hyperpronation of the upper limbs. Decerebrate rigidity occurs in severe metabolic disorders of the upper brain stem (anoxia/ischaemia, trauma, structural lesions, drug intoxication). A similar picture was rst observed by Sherrington (1898) following section of the brain stem of cats at the collicular level, below the red nuclei, such that the vestibular nuclei were intact. The action of the vestibular nuclei, unchecked by higher centres, may be responsible for the profound extensor tone. Decerebrate rigidity indicates a deeper level of coma than decorticate rigid ity; the transition from the latter to the former is associated with a worsening of prognosis. The lesion responsible for decorticate rigidity is higher in the neuraxis than that causing decerebrate rigidity, often being diffuse cerebral hemisphere or diencephalic disease, although, despite the name, it may occur with upper brainstem lesions. Cross References Coma; Decerebrate rigidity Deja Entendu A sensation of familiarity akin to deja vu but referring to auditory rather than visual experiences. Recurrent hallucinations or vivid dream-like imagery may also enter the differential diagnosis. Epileptic deja vu may last longer and be more frequent and may be associated with other features such as depersonalization and derealization, strong emotion such as fear, epigastric aura, or olfactory hallucinations. Epileptic deja vu is a complex aura of focal onset epilepsy; speci cally, it is indicative of temporal lobe onset of seizures and is said by some authors to be the only epileptic aura of reli able lateralizing signi cance (right). Deja vu has also been reported to occur in several psychiatric disorders, such as anxiety, depression, and schizophrenia. Cross References Aura; Hallucination; Jamais vu Delirium Delirium, also sometimes known as acute confusional state, acute organic reaction, acute brain syndrome, or toxic-metabolic encephalopathy, is a neurobe havioural syndrome of which the cardinal feature is a de cit of attention, the ability to focus on speci c stimuli. Diagnostic criteria also require a concurrent 102 Delirium D alteration in level of awareness, which may range from lethargy to hypervigilance, although delirium is not primarily a disorder of arousal or alertness (cf. The course of delirium is usually brief (seldom more than a few days, often only hours). On recovery the patient may have no recollection of events, although islands of recall may be preserved, corresponding with lucid intervals (a useful, if retrospective, diagnostic feature). However, it should be noted that in the elderly delirium is often superimposed on dementia, which is a predisposing factor for the development of delirium, perhaps re ecting impaired cerebral reserve. Risk factors for the development of delirium may be categorized as either predisposing or precipitating. It is suggested that optimal nursing of delirious patients should aim at envi ronmental modulation to avoid both understimulation and overstimulation; a side room is probably best (if possible). However, if the patient poses a risk to him/herself, other patients, or staff which cannot be addressed by other means, regular low-dose oral haloperidol may be used, probably in preference to atypical neuroleptics, benzodiazepines (lorazepam), or cholinesterase inhibitors. Occurrence and outcome of delirium in medical in-patients: a systematic literature review. Cross References Delirium; Dementia; Hallucination; Illusion; Intermetamorphosis; Misidenti cation syndromes; Reduplicative paramnesia Dementia Dementia is a syndrome characterized by loss of intellectual (cognitive) func tions suf cient to interfere with social and occupational functioning. Cognition encompasses multiple functions including language, memory, perception, praxis, attentional mechanisms, and executive function (planning, reasoning). These elements may be affected selectively or globally: older de nitions of dementia requiring global cognitive decline have now been superseded. Amnesia may or may not, depending on the classi cation system used, be a sine qua non for the diagnosis of dementia. Attentional mechanisms are largely preserved, cer tainly in comparison with delirium, a condition which precludes meaningful neuropsychological assessment because of profound attentional de cits. Multiple neuropsychological tests are available to test different areas of cognition. Although more common in the elderly, dementia can also occur in the pre senium and in children who may lose cognitive skills as a result of hereditary metabolic disorders. A distinction is drawn by some authors between cortical and subcortical dementia: in the former the pathology is predominantly cortical and neuropsychological ndings are characterized by amnesia, agnosia, apraxia, and aphasia. However, not all authors subscribe to this distinction and considerable overlap may be observed clinically. Cognitive de cits also occur in affective disorders such as depression, usually as a consequence of impaired attentional mechanisms. It may be dif cult to differentiate dementia origi nating from depressive or neurodegenerative disease, since depression may also 105 D Dementia be a feature of the latter. Impaired attentional mechanisms may account for the common complaint of not recalling conversations or instructions immediately after they happen (aprosexia). Behavioural abnormalities are common in demen tias due to degenerative brain disease and may require treatment in their own right. Because of the possibility of progression, reversible causes are regularly sought though very rare. Depersonalization is a very common symptom in the general population and may contribute to neurological presentations described as dizziness, numbness, and forgetfulness, with the broad differential diagnoses that such symptoms encompass. Such self-induced symptoms may occur in the context of meditation and self-suggestion.
