Necrotizing cellulitis and fasciitis may be difficult to recognize. When skin necrosis is not obvious, the diagnosis must be suspected if there are signs of severe sepsis (accelerated heart or respiratory rates, oliguria, mental confusion.) and/or some of the following local symptoms or signs: severe spontaneous pain, indurated edema, bullae, cyanosis, skin pallor, absence of lymphangitis, skin hypoesthesia, crepitation, muscle weakness, foul smell of exudates. Many risk factors are suspected. A recent case-control study demonstrated that using ibuprofen increased the risk of cellulitis complicating chickenpox in children. Evidence is lower for other risk factors that are present with a high prevalence in most series: local lesion of skin or mucous membranes (acute or chronic disease, traumatism, surgery.), diabetes, arteriopathy, alcoholism, obesity, immunosuppression, NSAIDs. The risk of streptococcal necrotizing fasciitis is increased when in contact with patients infected by the same streptococcus.

In order to know the clinical behavior of Human Balantidiasis, five symptomatic cases are reported (three from hospital and two from private practice), observed from December 1993 to December 1996 in the city of Huaraz (3,100 Mt above sea level). All patients were from Ancash, being their mean age 57,2 years old (3-85); 4/5 were male, and 3/5 were farmers. They bred pigs, lived in a rural environment and had no access to drinking water nor to sewage at home. The mean length of this disease was 22,8 days (10-60). Clinical symptoms were dysenteric diarrhea and abdominal pain accompanied by fever, pallor, asthenia, weight loss and dehydration. All five cases presented the parasite in the feces: one as a cyst, two as trophozolte, and the other two, both shapes. Two patients suffered serious complications: The first one had intestinal perforation, peritonitis and died, and the other one presented bronchopneumonia, low digestive hemorrhage and sepsis. Treatment included tetracycline, metronidazole and large spectrum antibiotic, if required. When we observe a patient with hemorrhagic or chronic severe diarrhea in Huaraz, who comes from the rural area and is a breeder of pigs, we must consider a diagnosis based on Human Balantidiasis.

Anemia is a major cause of morbidity and mortality among patients with sickle cell anemia. In this study, 108 episodes of severe anemia were prospectively evaluated in 108 patients with hemoglobin SS disease attending the pediatric sickle cell clinic of the University of Nigeria Teaching Hospital, Enugu, Nigeria. Young children between the ages of 2 and 4 years were found to be at the greatest risk of developing anemic crises (severe anemia). There was a gradual but progressive decline in the incidence of severe anemia in the age range 8-16 years old. Upper respiratory tract infections are the most commonly associated infections in patients with severe anemia. Others included malaria, septicemia, urinary tract infection, acute chest syndrome, and osteomyelitis. Their role in precipitating episodes of severe anemia among the patients studied could not be fully evaluated. Pallor, jaundice, and fever were the most commonly encountered symptoms in patients with severe anemia on admission. About half of the parents/guardians failed to notice severe anemia among the patients studied, perhaps due to the dark color of the African skin. Caregivers need to be educated on how to recognize anemia among patients with sickle cell anemia when they develop febrile episodes.

Findings of diminished or absent pulses, pallor on elevation, redness of the foot on lowering of the leg, sluggish refilling of the toe capillaries, and thickened nails or absence of toe hair are consistent with impaired arterial perfusion to the foot. When ischemia is recognized as contributing to pedal ulceration and infection in the diabetic foot, quantitation of its severity may be difficult. Standard clinical evaluation of trophic changes is limited in an infected foot with its accompanying swelling, edema, and erythema. A palpable pedal pulse does not preclude the possibility of the presence of limb-threatening ischemia. Additional non-invasive vascular studies should be undertaken for these patients. Management of the diabetic foot is often a complex clinical problem. However, the principles of care are simple, including correction of systemic factors, such as blood glucose control, cardiovascular risk factor management, and smoking, as well as local factor correction, such as debridement, pressure relief, infection control, and revascularization when indicated. When a patient presents with evidence of infection, adequate drainage and antibiotic therapy are mandatory. The next step should be performed to differentiate the more common neuropathic ulcerations from the truly ischemic ulceration. Symptoms of rest pain or claudication are not often helpful because many of these patients are asymptomatic as a result of the presence of their neuropathy and inactivity. If an infected foot requires debridement or open partial forefoot amputation, observing the wound on a daily base is also important. Once infection is eradicated, there should be prompt signs of healing, including the development of wound granulation within several days. If wounds are not showing signs of prompt healing, arteriography is necessary. Early aggressive drainage, debridement, and local foot amputations combined with liberal use of revascularization results in cumulative limb salvage of 74% at 5 years in high-risk groups. Others report that pedal bypass to the ischemic infected foot is effective and safe as long as infection adequately controlled. These studies strongly suggest that early recognition and aggressive surgical drainage of pedal sepsis followed by surgical revascularization is critical to achieving maximal limb salvage in the high-risk population. Patients who have diabetes present a unique challenge in lower extremity revascularization because of the distal origination of many bypasses, distal distribution of the occlusive disease, and the frequently calcified arterial wall. An aggressive multidisciplinary approach to foot disease associated with diabetes involving the primary care provider, medical specialists, interventional radiology, and podiatric, plastic, and vascular surgeons will provide optimal medical and surgical care. Peripheral vascular disease is highly treatable if intervention is instituted in a timely and collegial fashion.

The association of familial Mediterranean fever (FMF) and polyarteritis nodosa (PAN) has been well established. These patients have been reported to have an overall better prognosis than other PAN patients. Herein we report a patient with FMF and PAN who died of sepsis following a severe course of recurrent bleeding episodes which required multiple embolization attempts. The 39-year-old Turkish male presented with abdominal pain of 1-month duration. He had been diagnosed with FMF at the age of 24. On admission, he had pallor with general ill appearance. Rebound tenderness was obtained in the right upper abdominal quadrant. He had mild anemia, leukocytosis, thrombocytosis, and hypoalbuminemia. On the 2nd day of his admission, he developed hypotension with a rapid decline in hemoglobin level. Abdominal angiography showed multiple aneurysms in the branches of renal arteries, superior mesenteric artery, and hepatic arterial system including left renal infarct, suggesting PAN. He was put on high-dose steroids and oral cyclophosphamide. Despite medical treatment, he developed intense abdominal pain, hypotension, tachycardia, and a rapid fall in hemoglobin on four occasions. Active bleeding sites were embolized in two different angiography sessions. Although the patient experienced no more recurrent bleeding, he died of multiorgan dysfunction syndrome resulting from sepsis 6 weeks after admission. Polyarteritis nodosa associated with FMF may follow a grave course despite immunosuppressive therapy. Arterial embolization should be considered in the presence of bleeding aneurysms in addition to immunosuppressive therapy.

There were eleven cases of pure red cell aplasia diagnosed over a period of 2 years (January 2000-December 2001). All the patients had anemia with pallor and weakness being the presenting complaints. Hematological profile depicted normocytic normochromic anemia, reticulocytopenia and marked paucity of erythroid precursors on bone marrow aspiration and biopsy studies. In the present study, one case was of congenital pure red cell aplasia, in one other case of pyrexia of unknown origin, no definitive diagnosis could be made. Other associated diseases seen with pure red cell aplasia were thymoma, septicemia, protein energy malnutrition, non-Hodgkin's lymphoma, juvenile rheumatoid arthritis, acute myeloid leukemia, tuberculosis and hepatitis C. The association of pure red cell aplasia with haematologic malignancies is rare. There are very few case reports on pure red cell aplasia with hepatitis C.

The aim of the study was to the clinical features and long term follow up after treatment with Cladarbine in a tertiary care hospital. Seven patients with hairy cell leukemia were diagnosed between January 1990 till December 2003. Diagnosis in all the patients was established by bone marrow aspirates and trephine biopsy along with TRAP. In two patients the diagnosis was supplemented by flowcytometry and in another two patients by splenectomy. Six patients were male while one was female. Mean age was 47.7 years (range 36-64). Most common presenting features were pallor and weakness (n=5). All patients had splenomegaly. Blood count at presentation revealed that one patient had bicytopenia, two had isolated thrombocytopenia, and three had pancytopenia. Treatment responses were evaluable in seven patients. Complete response was seen in six patients (85.7%). One patient died after two months due to sepsis while 3 (50%) patients relapsed. Those who relapsed received another course of CDA and have maintained remission with a median duration of response of 48 months (20-48). From this small series we can conclude that CDA is an effective treatment for HCL and even it works very well in relapsed cases.

This is the first reported case of lymphoproliferative disease presenting with adrenal insufficiency after liver transplantation. A 38-year-old white man was admitted 8 months after transplantation for cryptogenic cirrhosis with fever (38-39 degrees C), chills, cough, and dyspnea. His blood pressure was 100/70 mm Hg, there was pallor of the conjunctiva, and a lymph node was palpable in the left groin. Laboratory analyses revealed the following values: serum sodium concentration (112 mmol/L), potassium (5.4 mmol/L), hemoglobin (7.8 g/L), white blood cell count (7.7 x 10(9)/L), glucose 3.9 (mmol/L), and mildly elevated liver functions. Abdominal ultrasound showed multiple hypoechoic solid-appearing lesions throughout the liver and spleen. Results of a biopsy specimen of the groin node confirmed polymorphic B-cell lymphoma. A negative Epstein- Barr virus screen before transplant became positive. The patient's fever increased to 40 degrees C. He subsequently developed sepsis and later, multiple organ failure. Autopsy confirmed extensive abdominal disease. The adrenal glands had been completely replaced by the tumor. Primary Epstein-Barr virus infection is associated with posttransplant lymphoproliferative disease. Replacement of the adrenal glands with a tumor produces a clinical picture of adrenal insufficiency.

In May 2006 a large mortality of several thousand round gobies Neogobius melanostomus (Pallas, 1814) occurred in New York waters of the St. Lawrence River and Lake Ontario. Necropsies of sampled fish from these areas showed pallor of the liver and gills, and hemorrhagic areas in many organs. Histopathologic examination of affected tissues revealed areas of necrosis and hemorrhage. Inoculations of fathead minnow Pimephales promelas (Rafinesque, 1820) cell cultures with dilutions of tissue samples from the necropsied gobies produced a cytopathic effect within 5 d post-inoculation. Samples of cell culture supernatant were tested using RT-PCR and confirmed the presence of viral hemorrhagic septicemia virus (VHSV). Sequence analysis of the VHSV isolate resulted in its assignment to the type-IVb subgroup. The detection of VHSV in a relatively recent invasive fish species in the Great Lakes and the potential impact of VHSV on the ecology and economy of the area will require further investigation and careful management considerations.

Sepsis is a leading cause of mortality for neonates in developing countries; however, little research has focused on clinical predictors of nosocomial infection of preterm neonates in the low-resource setting. We sought to validate the only existing feasible score introduced by Singh et al. in 2003 and to create an improved score. In a secondary analysis of daily evaluations of 497 neonates <or=33 weeks gestational age admitted to a tertiary care NICU in Dhaka, Bangladesh, we tested the Singh score and then constructed and internally validated our own bedside predictive score. The Singh score had low sensitivity of 56.6% but good positive predictive value (PPV) of 78.1% in our sample. Our five-sign model requiring at least one clinical sign of infection (apnea, hepatomegaly, jaundice, lethargy and pallor) had an area under the receiver operating characteristic of 0.70, sensitivity of 77.1%, and PPV of 64.9%. Our clinical sepsis score is the first bedside clinical screen exclusively for hospitalized, very premature neonates in a low-resource setting, and warrants external validation.
