Kawecki D, Kwiatkowski A, Michalak G, et al: Etiologic agents of bacteremia in the early period after simultaneous pancreas-kidney transplantation. The first human intestinal transplants occurred in the 1960s, but these transplants were suspended at that time because of dismal graft and patient survival owing to the lack of effective immunosuppressive protocols. Newer immunosuppressive regimens, advances in organ preservation, better donor and recipient selection, refinement in surgical techniques, earlier detection and treatment of infections, and improved postoperative critical care management have all played significant roles in the success of intestinal transplantation since the mid-1990s. Although intestinal transplantation remains the least frequent of all transplant types, 1-year graft survival rates have significantly improved and now approach those of other nonrenal transplants. As graft losses owing to technical reasons have diminished, immunologic and infectious issues remain primary challenges facing the field today. As the largest lymphoid organ in the human body and a host for potential infectious pathogens, the small bowel continues to be a difficult solid organ to successfully transplant [1–10]. Others have suggested that patients with ultrashort bowel remnants, complete portomesenteric thrombosis, slow growing tumors involving the mesenteric root, pseudo- obstruction, and frozen abdomen have indications for intestinal transplantation [4,8]. The causes of intestinal failure and intestinal transplantation differ for adult versus pediatric populations. Gastroschisis, necrotizing enterocolitis, malrotation with mid-gut volvulus, and atresias are the most common causes in pediatric patients; mesenteric arterial thrombosis/embolism, trauma, Crohn disease, and adhesions are the most frequent causes in adult patients . Loss of greater than 70% of intestine (considered ultra-short gut syndrome), however, usually necessitates some type of parenteral nutritional support. An upper gastrointestinal tract contrast series and abdominal and pelvic computed tomography scan are always necessary in order to plan gastrointestinal tract reconstruction during the transplantation. It is important to estimate actual bowel length and function (transit time with upper gastrointestinal series). Hepatic function should be evaluated carefully, and a transjugular or percutaneous liver biopsy is often required. If there is evidence of significant liver dysfunction, a combined liver-intestinal or multivisceral transplant may be indicated [5,12]. Patients with thrombotic disorders need specific hematologic tests to define hypercoagulable states (such as protein C and S deficiency, prothrombin G20210 A and factor V Leiden mutation, and hyperhomocysteinemia) . Conventional abdominal visceral angiography and a comprehensive evaluation of the upper and lower central venous system are mandatory in high-risk patients and those with thrombotic disorders. Absolute contraindications, such as advanced malignancy, severe systemic disease, active infection, and marked cardiopulmonary insufficiency, must be ruled out [2,6]. Surgical Procedure Unfortunately, the nomenclature to describe the technical aspects of intestinal transplantation has not been consistent in the literature, particularly when other organs are transplanted with the intestinal graft . Transplant experts convened at the 2007 International Small Bowel Transplant Symposium and attempted to standardize this nomenclature into two broad categories: with or without simultaneous a liver transplantation. Modifications to these operations then reflect that the transplantation occurs with or without excision of the native foregut. The indication for transplantation and the choice of organs to include in the composite graft are defined by the recipient’s baseline disease, vascular and gastrointestinal anatomy, associated diseases (such as liver failure, diabetes, exocrine pancreatic insufficiency, or renal failure), and functional quality of the other abdominal organs. The three most common types of intestinal transplants include (a) isolated intestinal transplants, (b) combined liver–intestine transplants, and (c) multivisceral or modified multivisceral transplants [1–8]. The most common intestinal transplantation is the isolated intestinal graft which includes the entire deceased donor jejunum and ileum, and is used for patients with intestinal failure that is limited to the small bowel. The arterial anastomosis is based on the recipient superior mesenteric artery or using a jump graft from the infrarenal aorta. Venous outflow is usually achieved with the anastomosis of the superior mesenteric vein to the native superior mesenteric vein or splenic vein; however, in some cases, systemic venous drainage to the inferior vena cava is required which can cause metabolic abnormalities. Gastrointestinal continuity occurs with a primary anastomosis between the recipient and donor proximal jejunum and the creation of a distal Bishop-Koop or loop ileostomy with or without anastomosis to the recipient colon.

Miscellaneous Causes of Anaphylaxis Insulin therapy has been associated with an increased risk of anaphylaxis, particularly when a patient on insulin therapy has a history of local wheal-and-flare reactions at the site of insulin injections and interrupts insulin therapy for more than 48 hours and then resumes it [11,118]. If heterologous serum must be used (antitoxin for snake bites, passive rabies immunization in developing countries, and antilymphocytic serum for organ transplantation), patients are usually evaluated for cutaneous sensitivity by first performing a scratch test with antitoxin or normal horse serum. As with all skin testing, the physician must be prepared to treat any systemic reactions that arise . Patients with mastocytosis appear to be at greater risk for developing anaphylaxis from Hymenoptera stings (even in the absence of IgE mediation) and from mast cell degranulating agents (see Table 69. Administration of diagnostic and therapeutic agents that might cause mast cell activation should be avoided in these patients. The quality of evidence and recommendations for diagnosis and management of anaphylaxis are summarized in Table 69.

We emphasize the importance of lesion morphology, that is, the shape, color, size, arrangement, and distribution of skin lesion in making a correct diagnosis. Because morphology evolves with the natural course of disease and with attempted therapeutic measures, it is helpful to request consultation early in the course of cutaneous disease. These reactions will be discussed in depth following a brief overview of more commonly occurring drug reactions. Clinically it appears as symmetric macules that may become slightly papular on the trunk and upper extremities, and may become confluent with time. Facial edema, mucosal lesions, blisters or sloughing of the skin, and laboratory abnormalities such as neutrophilia, eosinophilia, and elevated liver function tests may indicate the presence of a more serious drug reaction. Withdrawal of the causative drug is the most important treatment, although topical corticosteroids and oral antihistamines may be used for symptomatic relief. Exanthematous drug eruptions resolve without sequelae 1 to 2 weeks after the offending drug has been discontinued. The time from drug ingestion to clinical symptoms is generally 1 to 3 weeks, except for the aromatic anticonvulsants that can take up to 2 months to cause disease . Patients with a mucocutaneous mycoplasma-associated eruption present with oral mucosal erosions (94%), ocular involvement (82%), and urogenital involvement (63%). The initial cutaneous finding is irregularly shaped erythematous to purpuric macules distributed on the face and trunk. These may evolve into flaccid blisters that may be easily enlarged with lateral pressure (Nikolsky sign). Early lesions demonstrate necrotic keratinocytes, whereas advanced lesions reveal full thickness epidermal necrosis, and a 2005 study found that the density of the dermal mononuclear cell infiltrate correlates with the severity of disease and mortality rate . Prompt diagnosis and rapid cessation of the causative medication along with supportive therapy is the cornerstone of treatment. Careful monitoring of fluid volume, electrolytes, renal function, nutritional status, and evaluation for signs of sepsis should be standard. Uninvolved skin should not be manipulated, whereas involved skin should be covered with Vaseline-impregnated gauze and a topical antibiotic ointment. Debridement of necrotic skin may be followed by placement of artificial membranes or biologic dressings such as xenografts or allografts. Systemic antibiotics should not be started unless signs of sepsis are present because of the risk of selecting for antibiotic-resistant organisms, and prophylactic use of antibiotics has not been shown to improve outcomes. Unfortunately, there are no randomized double- blinded trials to support its use, and while some studies have shown mortality benefit with doses more than 1 g/kg/d, others have shown no benefits or even increased mortality associated with its use . Systemic corticosteroid pulse therapy early in the disease course has been shown to have benefits for preventing ocular complications, and topical high potency corticosteroids appear to prevent corneal epithelial stem cell loss and scarring . One point each is assigned for the presence of the following seven criteria: age >40 years, presence of malignancy, heart rate >120, initial epidermal detachment >10%, serum urea nitrogen >10 mmol per L, serum glucose >14 mmol per L, and serum bicarbonate <20 mmol per L. Healing of sloughed epidermis usually takes 3 weeks; however, survivors may experience delayed ocular scarring and visual loss, necessitating long-term follow-up with ophthalmology. The incidence is between 1/1,000 and 1/10,000 exposures and it is thought to occur with higher frequencies in patients of African ancestry . The rash is usually morbilliform, though erythroderma, pustules, vesicles, and purpuric areas may also be present. One study suggested that an erythema multiforme-like eruption may be more indicative of severe hepatic involvement . Initial systemic involvement may include pharyngitis, lymphadenopathy, hepatosplenomegaly, peripheral eosinophilia, abnormal liver function tests, arthralgias, pulmonary infiltrates, and interstitial nephritis. Several case series have shown that high eosinophil count is a poor prognostic factor with other indications of poor prognosis including pancytopenia, thrombocytopenia, and multiple medical comorbidities. Late sequelae involving the endocrine system, commonly the thyroid and pancreas, may develop weeks to months after drug withdrawal or rebound during corticosteroid taper. Although end-organ involvement is more common among older patients, young patients are more likely to develop autoimmune sequelae . One study found ampicillin and minocycline to be the most common medications associated with myocarditis . The most effective treatment is prompt diagnosis and cessation of the offending drug; most patients completely recover after drug withdrawal. In most cases, other than withdrawing the offending drug, prednisone at 1 mg/kg/d gradually tapered over 3 to 6 months is the current mainstay of treatment. However, there are no controlled clinical trials investigating the risks and benefits of systemic corticosteroids or other systemic treatments . Patch testing with the offending agent is frequently positive reflecting the dominant role of T cells in the disorder. Although drug-related in the vast majority of cases, there is some evidence showing the reaction is not always related to medication administration. More recently, spider bites have been reported as triggers in addition to possible viral causes [28–30]. The eruption is frequently of sudden onset and the majority of cases appear within 24 hours to several days of exposure to the offending agent. A fever of more than 38°C is followed by the appearance of tiny nonfollicular pustules on a background of generalized erythema and edema. Petechiae, purpura, vesicles, or target lesions may be present, and oral lesions may be observed among 20% of patients.

Retrospectively buy generic eriacta 100 mg on line, it was determined that the epidemic first arose in Guangdong Province, China, in 2002, where it affected at least 300 people. In February 2003, an infected business man traveling from China stayed in a hotel in Hong Kong and infected 10 other individuals staying on the same floor. These individuals in turn spread the illness to five different countries, including Hong Kong, Singapore, Vietnam, Thailand, and Canada. The illness was spread primarily through air droplets in closed spaces including airplanes. Family members and hospital personnel who failed to maintain respiratory precautions were primarily affected. The virus is also shed in the stool, and in one regional outbreak, infection spread through an apartment complex as consequence of a defective sewage system. In all, 8096 patients were identified worldwide, with a fatality rate of approximately 9. Several subsequent small clusters of infection occurred in 2004, originating from laboratory exposures. No human-to-human transmission of this novel coronavirus has been documented and the cases are currently under investigation. However, these cases are thought to have been secondary infections and the most likely natural reservoir is the horseshoe bat. This enveloped virus does not withstand drying, but may remain infectious in a warmer, moist environment. The virus attaches to cells in the respiratory tract and enters the cytoplasm, where it multiplies. Clinical Manifestations the infection attacks primarily adults aged 25–70 years who are healthy. Children are generally spared, although a few cases have been suspected in children under the age of 15 years. Infectiousness is thought to begin at about day 5 and peak at about day 10 of illness. Gastrointestinal symptoms are also usually absent at this stage, although diarrhea has been reported in some cases. The lower respiratory phase of the illness begins 3–7 days after the onset of symptoms. Patients begin to experience a severe, dry, nonproductive cough, accompanied by dyspnea and hypoxemia. Respiratory distress is often severe, with 10–20% of patients requiring intubation and mechanical ventilation. At the peak of the respiratory illness, 50% of patients develop leukopenia and thrombocytopenia (50,000–150,000/μ. Muscle and hepatic enzymes are often elevated early in the respiratory phase, reflecting the onset of rhabdomyolysis and hepatitis. Chest X-ray is usually normal during the febrile prodrome, but changes dramatically during the respiratory phase. The initial abnormalities seen are focal interstitial infiltrates that quickly progress to more generalized, patchy, interstitial infiltrates. In the late stages, these interstitial infiltrates develop into areas of dense consolidation. At autopsy, lung pathology may reveal pulmonary edema, hyaline membranes, and desquamation of type 2 pneumocytes. In later stages, fibroblast proliferation is observed in the interstitium and alveoli. Diagnosis For epidemiologic purposes, the diagnosis must be made quickly based on clinical criteria. In addition, sample collection technique is extremely important to maximize sensitivity and specificity. However, detectable antibody titers are generally not observed until the second week of the illness. At the present time, meticulous supportive care is all that medical science has to offer. Antibiotics may prevent bacterial superinfection and should be considered later in the disease course based on Gram stain findings (see Chapters 1 and 4). Oseltamivir, intravenous ribavirin, and combined ribavirin and corticosteroids have not been shown to be of benefit. A poorer prognosis was associated with older age: patients above the age of 60 years had a 43% mortality. Prevention Given the unavailability of curative therapies, infection control practices are critical for preventing the spread of this deadly infection. Respirator masks (N-95) should be worn in combination with gowns, gloves, and protective eyewear. Health care workers are at particularly high risk if present during intubation of an infected patient. Caused by a unique strain of coronavirus that is spread by aerosolized droplets and is excreted in stool. Illness occurs in two stages: a) Febrile prodrome b) Respiratory phase with infiltrates and hypoxia 4. Strict respiratory isolation and standard contact isolation are used to prevent transmission. Possibly infected patients who do not require hospitalization should be instructed not leave home until they have been asymptomatic for 10 days. Influenza A and B both cause epidemic illnesses, and influenza A can cause pandemics such as the 1918–1919 pandemic in which at least 20 million people died (Some estimates suggest that the number may have even reached 100 million. Thus, a strain of influenza A virus that was isolated in Hong Kong in 1968 is designated A/Hong Kong/03/68[H3N2]. Antigenic drift produces variant strains against which human populations have less protective antibody. Occasionally, influenza A virus acquires a completely different set of antigens by a process known as antigenic shift. The unique strains produced by antigenic shift can infect large segments of the population, because cross-reactive or protective antibodies are lacking, thus leading to a pandemic. The virus is thought to undergo antigenic shift by reassortment (exchange of segments of genome with avian influenza species). The process of reassortment and production of virulent human influenza species may occur in pigs, which can be infected with human and avian species of influenza alike. Influenza attack rates are highest in the very young, but the greatest morbidity and mortality are seen among elderly patients. Influenza is also particularly dangerous to people with underlying pulmonary disease or those who are immunocompromised. In the United States, influenza annually causes about 15 million excess cases of respiratory illnesses in young people and about 4 million cases in older adults. The virus is efficiently transmitted by aerosols of respiratory secretions generated by coughing, sneezing, and talking. In 1997, direct transmission of avian influenza from birds to humans was documented in Hong Kong. Sporadic cases of bird-to-human transmission have been occurring since 2003, primarily in Southeast Asia. Although occasional human-to-human transmission has been reported, efficient spread of avian strains among humans has not yet occurred. Recent data derived from sequencing of isolates obtained from formalin-fixed, paraffin-embedded lung tissue from 1918 influenza cases and a frozen sample from a victim buried in permafrost since 1918 have shed light on the nature of the 1918 pandemic strain. The sequences suggest that the 1918 strain was derived from an avian strain by adaptation to a human host rather than by reassortment. Experiments in mice also suggest that the 1918 strain possesses strong and unique virulence determinants. These findings have raised the possibility that the H5N1 avian influenza strains sporadically infecting humans today could mutate to become more infectious and transmissible among humans while retaining a high level of lethality.
