One percent fetal cells in the maternal circulation indicates a bleed of about 50 mL guaranteed erectile dysfunction treatment safe 30 gm himcolin. If a gastric aspirate contains blood shortly after birth, what test can determine whether the blood is swallowed maternal blood or fetal hemorrhage This test relies on the increased sensitivity of adult hemoglobin to alkali as compared with fetal hemoglobin. Adult hemoglobin gives a pink color that becomes yellow in 2 minutes or less, thereby indicating the denaturation of hemoglobin. Polycythemia is defined by a venous hematocrit of 65% because this exceeds the mean hematocrit found in normal newborns by two standard deviations. As the central venous hematocrit rises above 65%, there is an increase in viscosity. In neonates, some of the increase in viscosity with polycythemia is ameliorated by the lower viscosity of plasma. Because direct measurements of blood viscosity are not readily available in most laboratories, a high hematocrit level is thought to be the best indirect indicator of hyperviscosity. Because polycythemia results from a diverse array of etiologies, it is difficult to determine whether outcome depends more on etiology or the chronic elevation of viscosity. Many authorities recommend a partial exchange transfusion, regardless of symptoms, in infants with a central venous hematocrit level of at least 70% (because of the correlation with laboratory-measured hyperviscosity) or in those with a central hematocrit level of 65% or higher if there are signs and symptoms attributable to polycythemia. Describe the preferred method for partial exchange transfusions in polycythemic neonates. Partial exchange transfusions can be performed through an umbilical venous catheter, an umbilical arterial catheter, or a peripheral venous catheter. Aliquots equal to 5% of the estimated blood volume are withdrawn and historically have been replaced either with freshfrozen plasma, Plasmanate, 5% albumin, or normal saline. Adult plasma poses the risk for transfusion-acquired infections and may actually raise neonatal blood viscosity, whereas albumin offers no proven benefit. Therefore, the amount of blood volume to be exchanged with readily available crystalloid may be calculated using the following formula: Observed hematocrit A desired hematocrit Blood volume to be exchanged Observed hematocrit Ablood volume A weight kg 91. Based on numerous studies, a normal platelet count in neonates of any viable gestational age is defined as more than 150, 000/mm3. However, counts in the 100, 000 to 150, 000/mm3 range are frequently seen in healthy newborns. Consequently, patients with counts in this latter category should have repeat counts as well as further studies if illness is suspected. Surveys of neonatologists reveal tremendous variability in the thresholds used for transfusion of platelets especially because most are given prophylactically and are given not to treat active bleeding. Because the risk for bleeding is greatest in the first week of life, consensus opinion offers the guidelines shown in Table 12-10. What features on physical examination suggest a specific cause of thrombocytopenia What are the two main types of neonatal thrombocytopenia caused by maternal antibody Babies generally appear well, do not have hepatosplenomegaly, and have thrombocytopenia that persists for 3 to 12 weeks postnatally. In the mother with new-onset thrombocytopenia during pregnancy, how can one determine the risk to the fetus However, a previous history of an affected infant has been shown to be predictive in several studies. Although cordocentesis could provide direct data on the fetal platelet count, the risks of the procedure outweigh the risks of associated neonatal disease and thus cannot be justified. The prothrombin time reaches adult values at about 1 week of age, whereas the partial thromboplastin time does not attain adult values until 2 to 9 months of age. Treatment should be directed primarily at the underlying disease rather than just at the coagulation defects. In many cases, treatment of the former makes specific treatment of the latter unnecessary. However, in cases in which the stabilization of coagulopathy is not imminent, treatment with fresh-frozen plasma and platelets is recommended. In cases in which fluid overload is a major concern, exchange transfusion with fresh whole blood may be used. Unless vitamin K is given, these levels steadily decline during the first 3 days of life. Early hemorrhagic disease can be observed during the first few days of life in infants who are exclusively breastfed and who do not receive vitamin K prophylaxis at birth; they may bleed from various sites. Infants born to mothers who have received medications that affect the metabolism of vitamin K. All newborn infants exhibit a progressive rise in serum bilirubin concentrations following birth. Beginning with an average bilirubin in cord blood of 2 mg/dL, serum levels rise and peak at 5 to 6 mg/dL between 60 and 72 hours of life. If untreated, at least 1% to 2% of newborns will develop bilirubin levels of 20 mg/dL. The American Academy of Pediatrics recommends two clinical options individually or in combination: a predischarge total serum bilirubin (or transcutaneous bilirubin) and/or assessment of clinical risk factors. Predischarge bilirubins should be plotted on the chart in Figure 12-5 to assess risk. All infants discharged before the age of 24 hours should be seen by 72 hours of age by a qualified health care professional. Ofthetotal unconjugated bilirubin, most is bound to albumin and thus cannot cross the blood-brain barrier. Although the free bilirubin is believed to cause neurotoxicity, routine measurement in clinical practice is not available. Measurement of the bilirubin (mg/dL)-to-albumin (g/dL) (B/A) ratio may be helpful in managing jaundiced infants by acting as a surrogate for free bilirubin. Patients are thought to be at increased risk for bilirubin toxicity if the ratio is 8. What are the risks and benefits of restrictive versus liberal transfusion criteria in preterm infants However, the Iowa trial, which aimed for higher hemoglobin levels in the liberal group, demonstrated a reduction in brain injury and the combined outcome of brain injury or death. Perhaps, until more data are available, attempts to further restrict transfusions should be undertaken cautiously, especially in infants born weighting less than 1000 g. What screening tests should pregnant women have to identify infants at risk for hyperbilirubinemia In addition, they can progress rapidly to severe and life-threatening manifestations. When should phototherapy be instituted in infants who are at least 35 weeks of gestational age The American Academy of Pediatrics guidelines for instituting phototherapy in term and nearterm infants are shown in Figure 12-6. Hyperbilirubinemia in breastfed infants during the first week of life is called breastfeeding jaundice and is thought to be the result of poor caloric intake and/or dehydration. The cause of breast-milk jaundice is uncertain; however, possible etiologies include an increased enterohepatic circulation of bilirubin as a result of the presence of b-glucuronidase in human milk and/or the inhibition of the hepatic glucuronosyl transferase by a factor such as free fatty acids in some human milk samples. The incidence and duration compared with physiologic jaundice are noted in Table 12-12. Breastfed infants exhibit their maximal weight loss by day 3 of life and lose on average 6. With increased milk available, dehydration is less likely to occur, and the excretion of bilirubin by the gastrointestinal tract is more rapid. In breastfed infants who require phototherapy, the American Academy of Pediatrics recommends that breastfeeding should be continued.

This is an acquired deformity of the portion is the attic, the middle portion is mesotympanum, and external ear due to degeneration of cartilage as a result of the lowermost portion is the hypotympanum. The middle ear is lined by a single layer of flat homogeneous matrix (chondromalacia) and fibrous ciliated and nonciliated epithelium. The footplate of stapes first undergoes three semicircular canals, in the middle is the vestibule, and fibrous replacement and is subsequently replaced by sclerotic anteriorly contains snail-like cochlea. The exact etiology is not known but the condition has Besides the function of hearing, the stimulation of familial preponderance and autosomal dominant trait. It is seen more commonly in young males as a cause for sensori vestibular labyrinth can cause vertigo, nausea, vomiting and neural type of deafness. This is the term used for inflammatory Tumours and tumour-like conditions are relatively more involvement of the middle ear. The the usual source of infection is via the eustachian tube and lesions seen in the external ear are similar to those seen in the common causative organisms are Streptococcus the skin. Otitis media may be suppurative, serous or malignant tumours such as basal cell carcinoma, squamous mucoid. However, tumours presents as tense and hyperaemic tympanic membrane along and tumour-like lesions which are specific to the ear are with pain and tenderness and sometimes mastoiditis as well. This is an uncommon the chronic otitis media and project into the external auditory canal. Late stage shows lymphocytic cerumen-secreting apocrine sweat glands of the external infiltration and fibrous replacement. There is invariable history of acute or with degeneration of the underlying collagen, chronic chronic otitis media. They are the frontal air sinus, maxillary air sinus and the anterior ethmoid air cells, comprising the anterior group, while posterior ethmoidal cells and sphenoidal sinus form the posterior group. The anterior group drains into the middle meatus while the posterior group drains into the superior meatus and the spheno ethmoidal recess. Nasal mucous membranes as well as the lining of the nasal sinus are lined by respiratory epithelium (pseudostratified columnar ciliated cells). There is chronic and middle turbinate processes and the upper third of the inflammatory granulation tissue and foreign body giant cells around the cholesterol clefts and some pink keratinous material. The main physiologic functions of the nose are smell, filtration, humidification and warming of the air being present through which the squamous epithelium enters the breathed. Acute rhinitis or common cold is the common inflammatory disorder of the Histologically, the lesion consists of cyst containing nasal cavities that may extend into the nasal sinuses. It begins abundant keratin material admixed with cholesterol with rhinorrhoea, nasal obstruction and sneezing. In the nasal discharge is watery, but later it becomes thick and advanced cases, there may be pressure erosion of the bone. Allergic rhinitis chromaffin paraganglioma and is the most common benign occurs due to sensitivity to allergens such as pollens. Histologically similar tumours are IgE-mediated immune response consisting of an early acute seen in the carotid bodies and vagus (Chapter 27). The tumour may extend locally to involve the skull and brain but may rarely metastasise. Acute sinusitis is generally a complication of acute or allergic rhinitis and rarely secondary to dental sepsis. The ostia are occluded due to inflammation and oedema and this is a tumour of Schwann cells of 8th cranial nerve the sinuses are full. Acute sinusitis may become chronic due to incomplete other schwannomas but by virtue of its location and large resolution of acute inflammation and from damage to the size, may produce compression of the important mucous membrane. Sinusitis may rarely spread to produce neighbouring tissues leading to deafness, tinnitus, paralysis osteomyelitis and intracranial infections.

Microscopically, besides the structure of inflammatory or allergic polyp, large number of organisms of the size of erythrocytes with chitinous wall are seen in the thick walled sporangia. On rupture of a sporangium, the spores are discharged into the submucosa or on to the surface of the mucosa. The intervening tissue consists of inflam matory granulation tissue (plasma cells, lymphocytes, histiocytes, neutrophils) while the overlying epithelium Figure 18. The overlying mucosa is covered shows hyperplasia, focal thinning and occasional partly by respiratory and partly by squamous metaplastic epithelium. The underlying stroma is oedematous and contains inflammatory cells ulceration (. This is a chronic destructive result of prolonged chronic inflammation causing poly inflammatory lesion of the nose and upper respiratory poid thickening of the mucosa. They may be allergic or inflam airways caused by diplobacilli, Klebsiella rhinoscleromatis.

The condition begins as a common cold mucosa of the maxillary sinus and appear in the nasal cavity. Histologically, there is extensive infiltration by foamy Grossly, they are gelatinous masses with smooth and histiocytes containing the organisms (Mikulicz cells) and shining surface. These include: tuberculosis, leprosy, of eosinophils and hyperplasia of mucous glands. The spores are present in sporangia as well as are intermingled in the inflammatory cell infiltrate. Leprosy begins as a nodule that may ulcerate and and paranasal sinuses are squamous cell carcinomas, perforate the septum. Syphilis may involve the nose in congenital form causing commonly in the elderly with history of heavy smoking and destruction of the septum, or in acquired tertiary syphilis in severe chronic sinusitis, in nickel refinery workers and in the form of gummas perforating the septum.

Granulomatous Prostatitis Granulomatous prostatitis is a variety of chronic prostatitis, probably caused by leakage of prostatic secretions into the tissue, or could be of autoimmune origin. Grossly, the gland is firm to hard, giving the clinical impression of prostatic carcinoma on rectal examination. Histologically, the inflammatory reaction consists of macrophages, lymphocytes, plasma cells and some multinucleate giant cells. Sectioned condition in men and considered by some as normal ageing surface of enlarged prostate shows soft to firm, grey-white, nodularity process.

Histogenesis of prostatic adenocarcinoma medium-sized, lined by a single layer of cuboidal or low has been documented as a mutistep process arising from columnar cells. Grossly, the prostate may foamy cytoplasm, dark cells have homogeneous basophilic be enlarged, normal in size or smaller than normal. The tumour spreads within the gland by direct ii) Growth pattern of the tumour in relation to the stroma. In late stage, the tumour the diagnosis of prostatic carcinoma is made by may extend into the bladder neck, seminal vesicles, trigone cytologic, biochemical, radiologic, ultrasonographic and and ureteral openings. Distant spread occurs by both lymphatic and established by histopathologic examination of transrectal haematogenous routes. The earliest diagnosis and monitoring the prognosis of prostatic metastasis occur to the obturator lymph node. In such symptomatic cases, clinical between 4 and 10 (normal 0-4 ng/ml) is highly suspicious features are: urinary obstruction with dysuria, frequency, (10% risk) but value above 10 is diagnostic of prostatic carci retention of urine, haematuria, and in 10% of cases pain in noma. Treatment of prostatic carcinoma consists of surgery, the tumour palpable by rectal digital examination but radiotherapy and hormonal therapy. The mons the older nomenclature vulvar dystrophy has been replaced pubis and labia majora are covered externally by skin with by more descriptive and clinically relevant term, non hair follicles, sebaceous glands and sweat glands including neoplastic epithelial disorders of vulval skin and mucosa of apocrine glands. The term is applied to chronic lesions of the vulva minora and vestibule are covered by stratified squamous characterised clinically by white, plaque-like, pruritic epithelium. But white lesions may represent other are racemose type and their secretions are released during depigmented conditions as well such as vitiligo, inflam sexual excitement. The condition presents with intense pain, small, coalescent, yellowish-blue macules or papules which swelling and fluctuant mass which can be incised and produce thin and shiny parchment-like skin. Microscopic examination shows the usual appearance of Clinically, the patient, usually a post-menopausal woman, acute suppurative inflammation with neutrophilic infil complains of intense pruritus which may produce excoriation tration, hyperaemia, oedema and epithelial degeneration. Microscopically, the natively, the chronic process evolves from repeated attacks following characteristics are seen (. Thinning of the epidermis with disappearance of rete the chronic inflammatory process terminates into fluid-filled ridges. Amorphous homogeneous degenerative change in the 3-5 cm in diameter and readily palpable in the perineum, dermal collagen. Histologic examination shows variable lining of the cyst Lichen sclerosus is not a premalignant lesion and responds varying from the transitional epithelium of the normal favourably to topical treatment with androgens. The stroma consists of loose fibrous and myxomatous connective tissue with some adipose tissue and blood vessels.

The four Ig G subclasses are numbered in order of their level in serum erectile dysfunction treatment options articles purchase himcolin on line amex, IgG1 being found in greatest amounts and IgG4 the least. This species has been divided into five types (A through E) on the basis of four major lethal toxins: Chlamydia pneumoniae prduces the glycogen negetive inclusion bodies that are much like of Chlamydia psittaci and are sulfonamide-resistant. Serology using the Microimmunofluroscent test is the bmost sensitve method for the detection of Chlamydia pneumoniae infection. This test is the species specific not the complement fixing antibody detection by complement fixation test. Because the complement fixing antibodies are against the group specific antigen so detection of these antibodies are not species specific. It is routinely performed at about 10 to 12 weeks of gestation, it allows for an earlier detection of abnormalities and a safer pregnancy termination, because there is an increased association of limb defects (Oromandibulo digital dysplasia) when the procedure is performed before the 9th week. Elevation of Amniotic fluid alpha fetoprotein level without increased acetyl cholinesterase can be due to other etiology or from blood contamination. When the cervical length measured by vaginal ultrasound was less than 50th percentile (< 37 mm), risk of preterm delivery was increased 3. If manual measured cervix was shorter than the 50th percentile (18 mm), premature birth was increased 2. Answer is 4 Williams 21st/ 759 Factors that favor the likelihood of large fetus 1) Obesity 5) Male fetus 2) Multiparity 6) Previous infant > 4 kg 3) Prolonged gestation 7) Race and ethnicity 4) Maternal age. Which of the following statements is incorrect in relation to pregnant women with epilepsy The rate of congenital malformation is increased in the offspring of women with epilepsy. Women taking antiepileptic drugs should receive the Folic acid supplementation as most of these agents deplete this nutrient. The rate of congenital malformation is increased in the offspring of women with epilepsy even when patient is not taking the antiepileptics. Pre-eclampsia, heart disease, malnutrition may be life threatening and important cause of fetal growth retardation. All of the following appear to decrease hot flushes in menopausal women except: 1. Lipincott Roven publication, S Jean Emans, Marc R Pediatric and adolescent gynecology 4th ed. In Klippel-Feil syndrome, the patient has all of the following clinical features except: 1. In Radionuclide imaging the most useful radio pharmaceutical for skeletal imaging is: 1. Subtrochanteric fractures of femur can be treated by all of the following methods except: 1. It is called the burst fracture (Jefferson fracture), which is characterized by 4 fracture 2 in posterior arch and 2 in anterior arch.

The coagulation profile in a 13-year old girl with Menorrhagia having von Willebrands disease is: 1. All of the following are true about manifestations of vitamin E deficiency except: 1. Differential expression of same gene depending on parent of origin is referred to as: 1. The chances of having an unaffected baby, when both parents have achondroplasia, are: 1. When asphyxia occurs prenatally then high level of circulating steroids already leads to lung maturation. On examination, liver and spleen were enlarged 4 cm and 3 cm respectively below the costal margins. Bone marrow examination revealed a cellular marrow comprising 45% blasts and 34% eosinophils and eosinophilic precursors. Kidney biopsy from a child with hemolytic uremic syndrome characteristically most likely presents features of: 1. One of the intestinal enzymes that is generally deficient in children following an attack of severe infectious enteritis is: 1. Some of the larger macrophages becomes multinucleated to form aschoff giant cells. Concomitant involvement of the endocardium and the left sided valves by inflammatory foci typically result in fibrinoid necrosis within Cusps or along the cord. All of the following statements are true regarding reversible cell injury, except: 1. Note amorphous density in mitochondrial matrix is a feature of reversible injury. Tartarate resistant acid phosphatase positivity is typically seen in hairy cell leukemia. All of the following vascular changes are observed in acute inflammation, except: 1. In apoptosis, Apaf-1 is activated by release of which of the following substances from the mitochondria Patients with IgD myeloma may present with no evident M-spike on serum electrophoresis. In smoldering myeloma plasma cells constitute 10-30% of total bone marrow cellularity. In a patient with multiple myeloma, a monoclonal light chain may be detected in both serum and urine. Myelodysplastic syndrome also K/a smouldering leukemia because it is having blast cells < 30% but > 10%. But iwhen the ward leukemia is used, it always means that cells are > 20% of circulating W. Serum albumin has a long half-life: 15 to 20 days, with approximately 4% degraded per day. Because of this slow turnover, the serum albumin is not a good indicator of acute or mild hepatic dysfunction; only minimal changes in the serum albumin are seen in acute liver conditions such as viral hepatitis, drug-related hepatoxicity, and obstructive jaundice. In hepatitis, albumin levels below 3 g/dL should raise the possibility of chronic liver disease. One exception is the patient with ascites in whom synthesis may be normal or even increased, but levels are low because of the increased volume of distribution Q.

This produce hydrogen sulfde, which Shigella does muscle is not utilized in the psoas sign maneu not. The obturator nerve there is contamination of food or water by ani originates from the lumbar plexus and inner mal feces. It maintains duodenal pH by stimulat haled infection by Bacillus anthracis, which ing bicarbonate secretion by the pancreas, thus is not connected to any of the other symptoms neutralizing gastric acid. These symptoms de scribe rheumatic fever, which is caused by an Answer E is incorrect. Helicobacter the intern is thinking about octreotide, a so pylori is the most common cause of duodenal matostatin analog used to treat acromegaly. It can be diagnosed potent inhibitor of growth hormone secre with esophagogastroduodenoscopy or a urease tion; it also suppresses the release of a number breath test. The standard frst line therapy is one-week triple therapy consist Answer A is incorrect. Unlike duodenal ulcers, gastric the treatment of acromegaly, and no analogs ulcers are worsened by food; patients usually have been created. Gastrin is a hormone would not be a primary part of the treatment released by stomach G cells in response to plan for this patient with confrmed Helico stomach distention, vagal stimulation, and bacter pylori infection. Through the actions of gastrin on pa rietal cells, the end result of gastrin release is Answer C is incorrect. Gastrin also causes Ellison syndrome have gastrin-secreting tu chief cells to release pepsinogen for break mors of the pancreas and duodenum. Gastrin is not indicated for will have fndings indicative of acid hyperse the treatment of acromegaly and does not have cretion, such as several refractory ulcers. Sulfadiazine plus pyri adenoma), and does not indicate that the pa methamine is the primary treatment for Toxo tient has an elevated serum gastrin. Metoclopramide is likely suffering from acute gastroenteritis, used primarily as an anti-emetic and a proki probably of viral origin. It would not be frst-line therapy eral causes of hypoalbuminemia, the most for a patient with a duodenal ulcer. Ranitidine is a is simply a dilutional effect due to the large histamine2-receptor antagonist. This type of hy used as a treatment for gastroesophageal refux poalbuminemia is also seen in congestive heart disease to reduce the amount of acid in the failure. This parasite It is unlikely that this young and healthy indi is treated with metronidazole. It spreads via vidual has severe enough liver disease to cause oral-fecal transmission in its cyst form and then a dysfunction in albumin synthesis. Malabsorptive states, num and jejunum, and causes a combination such as short bowel syndrome and celiac of malabsorption with diarrhea through a still sprue, can lead to decreased ability to absorb incompletely understood mechanism. Diag cause a protein defciency severe enough to nosis is made via direct examination of stool cause hypoalbuminemia. This syndrome would also be clas to treat Plasmodium, the organism that causes sically accompanied by massive proteinuria, malaria. Poor nutritional status treat Trypanosoma brucei gambiense and Try causes hypoalbuminemia due to insuffcient panosoma brucei rhodesiense, the causes of Af protein intake. Specifcally, it is used history of vomiting would not cause a severe in cases of central nervous system penetration. Nifurtimox is the pri buminemia, which is generally seen only after mary treatment for Trypanosoma cruzi, the long-term protein defciency. These calcium carbonate, which this patient is likely cysts lack a true epithelial lining.

Furthermore, no drug interactions would be expected between aspirin and ciprofoxacin. Gastrin levels are ever, it does not signifcantly affect the metab regulated by a feedback loop. Misoprostol is a prosta crine fashion, binding to G-cells in the gastric glandin E1 analog that can be used to prevent antrum and inhibiting gastrin release. It is also used as effectively raise the intragastric pH so that gas a medical abortifacient in many countries and trin levels rise two to four-fold. Omeprazole is therefore strictly contraindicated in pregnant is associated with atrophic gastritis due to hy women. It is associ tric acidity, but does not affect the intestinal ated with constipation and hypophosphatemia. Cimetidine is an H2 cess often occurs in young patients after con antagonist and is associated with headache, suming large amounts of alcohol.
