As before, some new subjects, such as cutaneous anthrax, have every chapter has been updated extensively, but our been forced into the new edition by outside events. We are most grateful we would have to leave out too many old favourites to Graeme Chambers who has redrawn the previous that have stood the test of time, but have still not been line drawings as well as creating the new gures for evaluated properly. We have pruned these mission to use illustrations previously published in back, but have put more physiology and pathology the following books: into the relevant clinical chapters where it should be of more use to a doctor struggling through a busy Champion, R.

Any product mentioned in this pub lication should be used in accordance with the pre scribing information prepared by the manufacturers. Preface to the rst edition Some 10% of those who go to their family doctors do aand of course their patients. Here, we few years, but the subject still baf es many medical mention only those preparations we have found to be studentsaon both sides of the Atlantic. Family doctors who the eruptions clearly enough, but are asked about this topic can nd cannot describe or identify them. Their problems in the classi cation of patients quickly sense weakness and lose faith. Many doc To do so they will need some understanding of tors are put off by the cumbersome Latin names left the anatomy, physiology and immunology of the skin behind by earlier pseudo-botanical classi cations. Failing to browse through dermatology journals online this, some chapters are based on a shared physiology, ( Modern research will surely Further reading soon reallocate their positions in the dormitory of dermatology. We rely heavily Fitzpatricks Dermatology in General Medicine, on those of the British Association of Dermatologists 5th edn.

Which of the following is the most appropriate initial diagnostic test to gastritis diet 2000 order 100 mg allopurinol mastercard confirm the diagnosis A family member has noted some yellowness of her eyes gastritis diet 90x purchase allopurinol 100mg with amex, but she denies darkening of the urine gastritis diet order allopurinol with paypal. Laboratory data include hemoglobin of 9 g/dL, reticulocyte count of 8%, a bilirubin in the serum of 2 mg/dL (indirect reacting), and some microspherocytes on peripheral smear. A 57-year-old man, with a history of chronic alcohol ingestion, is admitted to the hospital with acute alcoholic intoxication and lobar pneumonia. Physical examination reveals pallor; a large tender liver; and consolidation of the right lower lobe. An 82-year-old woman is brought to the hospital because of functional decline at home and an inability to care for herself. She has a prior history of hypertension and dyslipidemia, and her medications include hydrochlorothiazide and atorvastatin. She looks disheveled, pale, and has muscle wasting; her heart and lungs are clear and there are no focal neurologic findings. Which of the following vitamin deficiencies is most likely responsible for her pancytopenia A 39-year-old man with chronic alcoholism is brought to the hospital after a fall, while intoxicated. Which of the following findings is most likely to be seen on his peripheral blood film A 56-year-old woman presents with feeling light-headed when standing up and 3 days of passing dark black stools. On examination, she is alert, blood pressure is 90/60 mm Hg supine and 76/60 mm Hg standing. Her abdomen is distended with signs of ascites, it is nontender, and there are multiple bruises on the legs. Which of the following coagulation factors are most likely deficient in this patient An 18-year-old man, of Italian extraction, is found to have a hypochromic microcytic anemia of 10 g/dL. In addition, there are a fair number of anisocytosis, poikilocytosis, and target cells seen on the blood film. A 28-year-old man, originally from West Africa, is found on routine examination to have splenomegaly. Questions 59 through 63: For each patient with a hypochromic microcytic anemia, select the most likely diagnosis. A 43-year-old man, in hospital for 2 weeks with pancreatitis, is anemic with hemoglobin of 9. The blood film shows slightly microcytic hypochromic red cells, and the reticulocyte count is 0. A bone marrow aspirate reveals erythroid precursors that have accumulated abnormal amounts of mitochondrial iron. Questions 69 through 72: For each patient with a bleeding disorder, select the most likely diagnosis. An 18-year-old man develops excessive bleeding 2 hours after wisdom tooth extraction. He has a history of easy bruising after playing sports, and of minor cuts that rebleed. His examination is normal, except for the tooth extraction site, which is still oozing blood. A 19-year-old man is brought to the hospital after injuring his knee playing football. The lungs are clear, heart sounds normal, and abdomen is soft with no palpable spleen or liver. Cryoglobulins are antibodies that precipitate under cold conditions and are associated with several diseases. There are three main types of cryoglobulin syndromes based on the immunoglobulin composition of the precipitating antibody. The other syndromes would not generally be temperature sensitive, and do not have an association with hepatitis C virus infection. Although similar to normal azurophilic granules in content and staining properties, they are distinguished by their gigantic size.

Between 7/2004 6/2008, 36% of recipients were treated for acute rejection which typically occurs in the first 6-12 months after transplantation. Improved diagnosis and treat ment has decreased the risk of death from acute rejection from 4. Acute rejection is one of the major risk factors for chronic rejection which remains the most common cause of death after the first year of transplant. Current management/treatment At the time of transplantation, many transplant centers now employ an induction regimen that includes infusion of an antibody that targets activated host lym phocytes. Maintenance immunosuppressive therapy after lung trans plantation typically consists of a three-drug regimen that includes a calcineurin inhibitor (cyclosporine or tacrolimus), an antimetabolite (azathioprine or myco phenolate mofetil), and steroids. Short courses of intravenously pulsed corticosteroids, followed by a temporary increase in maintenance doses for a few weeks, are the preferred treatment for uncomplicated acute rejection. Additional therapeutic options are augmentation of existing regimens and/or switching within classes of drugs. Overall, the reinfusion of the treated leukocytes mediates a specific suppression of both the humoral and cellular rejection response, and thereby induces tolerance of the allograft, thus prolonging the survival of transplanted tissues and organs. A common regimen includes one cycle every two weeks for the first two months, followed by once monthly for two months (total of 6). In recent large series: total of 24: 10 during first month, biweekly for 2 months and then monthly for 3 months. Replacement fluid: N/A Duration and discontinuation/number of procedures the optimal duration remains unanswered. In a recent 10 year single center experience, 12 cycles were the initial dose and long term contin uation was recommended for responders. Malaria accounted for an estimated 881,000 deaths in 2006 with 91% occurring in Africa, where P. The Plasmodia life cycle includes an intraerythrocytic stage of reproduction, which is responsible for many of the pathological manifestations of the disease and the vehicle for transmission by mosquitoes or blood transfusion. The stand ard diagnostic test for malaria involves identification of typical intraerythrocytic organisms on thick or thin blood smears. Infectious symptoms usually begin within 10 days to 4 weeks after inoculation by an infected mosquito. Parasitemia leads to hemolysis and activation of inflam matory cells and cytokines that cause fever, malaise, chills, headache, myalgia, nausea, vomiting and, in some cases, anemia, jaundice, hepatosplenomegaly and thrombocytope nia. Severe malaria, which incurs an overall mortality rate of 15-20% in treated patients, is characterized by impaired consciousness/coma, multiple seizures, pulmonary edema, acute respiratory distress syndrome, shock, disseminated intravascular coagulation, spontaneous bleeding, renal failure, jaundice, hemoglobinuria, severe ane mia (Hgb <5 g/dL) acidosis, other metabolic derangements and/or parasitemia >5%. Because severe complica tions can develop in up to 10% of cases, symptomatic patients with a positive travel history should be promptly evaluated and treated. Current management/treatment Malaria treatment is based on the clinical status of the patient, the Plasmodium species involved and the drug-resistance pattern predicted by the geographic region of ac quisition. Single or combination oral agent regimens include chloroquine, hydroxychloroquine or quinine (alone or with doxycycline, tetracycline or clindamycin), atovaquone-proguanil, artemether-lumefantrine, mefloquine and primaquine. Severe malaria should be treated promptly with intravenous quinidine gluconate or quinine plus doxycycline, tetracycline or clindamycin. Falciparum malaria with more severe anemia, hypoxemia, hyperparasitemia, neu rologic manifestations. A number of reports and small case series have described rapid clinical improvement of severe P. However, a meta-analysis of 279 patients from 8 case-controlled trials found no survival benefit of manual exchange transfusion compared to antimalarials and aggressive supportive care alone. Notably, the exchange transfusion methods in those trials were not comparable, the patients in the transfusion groups were more ill, additional differences in treatment populations and confounding variables were not adjusted in the analysis and other important out comes, such as duration of coma and severe end-organ complications. Quinidine administration should not be delayed for the procedure and can be given concurrently. Rare case reports have described the use of adjunctive plasma exchange with automated red cell exchange; however, lack of published experience precludes assessment of this procedure in patients with severe malaria. The risks include circulatory overload, transfusion reactions, blood-borne infection (especially in developing countries), hypocalcemia, red blood cell allosensitization and pos sible need for central venous access. Treatment should be continued for higher parasite levels with ongoing signs and symptoms of severe infection. Clinical symptoms include sensory disturbances, unilateral optic neuritis, diplopia, limb weakness, gait ataxia, neurogenic bladder and bowel symptoms.

Diagnosis Tuberous sclerosis is easily diagnosed by the cutaneous symp toms, which include multiple angiofibroma of the face. Treatment, Prognosis Dermabrasion, excision, cryotherapy and laser therapy are conducted on the cutaneous lesions for cosmetic reasons, which nevertheless tend to recur. Drug therapy is useful for convulsive Clinical images are available in hardcopy only. The prognosis depends on the severity of cerebral tumorous lesions and renal leisions. Peutz-Jeghers syndrome Outline Autosomal dominantly inherited, it is characterized by pigmentation on the lips, oral mucosa and distal extremi ties, and gastrointestinal polyposis. Clinical features Skin pigmentation Flat, asymptomatic, sharply margined, blackish-brown mac ules of 2 mm to 10 mm in diameter occur symmetrically on the lips, oral mucosa, palms and soles (distal extremities in particu lar) (Fig. Pigmentation appears between the time of birth and infancy, and tends to increase in Clinical images are available in hardcopy only. Most cases of gas trointestinal polyposis are histologically hamartoma; the tissue structure of the lesion is normal and malignant transformation rarely occurs (Table 20. Peutz-Jeghers syndrome is autosomal dominantly inherited; however, about half of all cases occur sporadically. Sites where polyps likely Canceration Disease Inheritance pattern Cutaneous symptoms form of polyp Peutz-Jeghers Autosomal dominant Jejunum in many cases Sometimes Pigmented macules on the lips, oral syndrome mucosa and palms Cronkhite-Canada Not inherited Entire digestive tract No Alopecia, nail plate abnormality, pigmented syndrome macules on the dorsum of hands Gardner syndrome Autosomal dominant Large intestine in most cases Yes Neurofibromatosis, lipoma, dental dysplasia Turcot syndrome Autosomal recessive Large intestine Sometimes Nervous system tumors Pathology Melanocytes and melanin pigment increase in the epidermal basal layer. There is hyperpigmentation in the crista profunda intermedia, which is the thick portion of the epidermis. Differential diagnosis As with Peutz-Jeghers syndrome, Cronkhite-Canada syndrome is characterized by gastrointestinal polyposis and pigmentation Fig. However, the onset of Cronkhite-Canada syndrome is at middle age or later and the condition is not inherited. Treatment, Prognosis Alexandrite laser therapy and dermabrasion are effective in reducing pigmentation when there are cosmetic concerns. They become pustules or ero sion, persisting for several weeks to several months before heal ing gradually. Verrucous and lichenoid stage: After the blisters subside (6 to 12 weeks after birth), multiple hyperkeratotic verrucous papules occur, mainly on the distal extremities. Pigmented stage: Grayish-brown or purplish-brown pigmenta Clinical images are available in hardcopy only. The pigmentation often appears in linear, droplet like, marbled and reticular patterns (Fig. Strabismus is the most common such symptom, followed in frequency by cataract, glioma and microphthalmos. Central symptoms: Epilepsy and intelligence impairment may be caused in rare cases. It is an X linked dominant trait that is usually lethal in males; most male fetuses with the genetic abnormality are not carried to term, which is why more than 95% of all patients are females. Pathology, Laboratory findings 20 There is eosinophilic infiltration in the intraepidermal blisters of the first stage (Fig. Verrucous papules of the sec ond stage are structurally similar to epidermal nevus. Diagnosis, Differential diagnosis It is easy to diagnose incontinentia pigmenti by the characteris tic clinical features. The condition is sometimes misdiagnosed as epidermolysis bullosa because of blistering at birth; however, incontinentia pigmenti can be distinguished by its eosinophilic infiltration. Clinical images are available in Clinical images are available in Clinical images are available in hardcopy only. Treatment, Prognosis Complications associated with incontinentia pigmenti and deformities should be promptly treated. As the skin lesion heals spontaneously in many cases, symptomatic therapy may be per formed if necessary. About half of all male fetuses whose mothers have incontinentia pigmenti do not survive to term.

Primary biliary cirrhosis is primarily a disease of middle-aged females and is characterized by pruritus gastritis symptoms flatulence discount 100 mg allopurinol overnight delivery, jaundice, and hypercholesterolemia. More than 90% of patients have antimitochondrial autoantibodies, particularly to mitochondrial pyruvate dehydrogenase. A characteristic lesion, called the florid duct lesion, is seen in portal areas and is composed of a marked lymphocytic infiltrate and occasional granulomas. Primary sclerosing cholangitis is characterized by fibrosing cholangitis that produces concentric onion-skin fibrosis in portal areas. It is associated with chronic ulcerative colitis, one type of inflammatory bowel disease. Peliosis hepatis is an abnormality of the hepatic blood flow that results in sinusoidal dilation and the formation of irregular blood-filled lakes, which may rupture and pro duce massive intraabdominal hemorrhage or hepatic failure. Peliosis hepatitis is most often associated with the use of anabolic steroids, but more rarely it may be associated with oral contraceptives. Reyes syndrome, characterized by microvesicular fatty change in the liver and encephalopa thy, has been related to the use of salicylates in children with viral illnesses. Acetaminophen toxicity results in centrilobular liver necrosis, while estro gens may be related to thrombosis of the hepatic or portal veins. Several Gastrointestinal System Answers 381 hepatic tumors are related to exposure to vinyl chloride, including angiosarcoma and hepatocellular carcinoma. Ethanol is taken up by the liver and is converted into acetaldehyde by either alcohol dehydrogenase (the major pathway), microsomal P-450 oxidase, or peroxiso mal catalase. Increased lipolysis increases the amount of free fatty acids that reach the liver. This fibrosis is the result of liver cell necrosis and regenerative hepatic nodules. These nodules consist of hyperplastic hepato cytes with enlarged, atypical nuclei, irregular hepatic plates, and distorted vas culature. It is thought that the fibro sis is the result of fibril-forming collagens that are released by Ito cells, which are fat-containing lipocytes found within the space of Disse of the liver. They normally participate in the metabolism and storage of vitamin A, but they can secrete collagen in the fibrotic (cirrhotic) liver. These Ito cells are initiated by unknown factors and then are further stimulated by such factors as platelet derived growth factor and transforming growth factor-beta to secrete collagen. In contrast to Ito cells, endothelial cells normally line the sinusoids and demarcate the extrasinusoidal space of Disse. Attached to the endothelial cells are the phagocytic Kupffer cells, which are part of the monocyte-phagocyte system. Bile ducts, and thus the epithelial cells that form them, are found in the portal triads of the liver. Patients are usually asymptomatic, but can develop fatigue, malaise, right upper quadrant abdominal discomfort, and hepatomegaly. Laboratory findings include elevated liver enzymes along with increased serum cho lesterol, triglyceride, and glucose. Ultrasonography reveals a diffuse increased density that is similar in appearance to cirrhosis. Liver biopsy, which is the best diagnostic test for confirming the diagnosis, reveals macrovesicular steatosis, which refers to the accumulation of neutral lipid (triglyceride) in hepatocytes. Steatosis can be divided into two types: macrovesicular steatosis, with a single large vacuole, peripheral nucleus, and microvesicular steatosis, with many small vacuoles, central nucleus. Primary (familial) hemochro matosis is a genetic disorder of iron metabolism that is inherited as an autoso mal recessive disease. The classic clinical triad for this disease consists of micronodular pigment cirrhosis, diabetes mellitus, and skin pigmentation. In the majority of patients, serum iron is above 250 mg/dL, serum ferritin is above 500 ng/dL, and iron (transferrin) satura tion approaches 100%.
