Absidiosis was produced experimentally in rabbits by intravenous inoculation of 1.4 x 10(5) spores of Absidia corymbifera. Infected rabbits exhibited a rise in body temperature, anorexia, dullness, listlessness, diarrhoea, occasional blindness, convulsions and death in some cases. Mortality occurred mainly between 6 to 9 days post infection (DPI) and overall mortality was 50 per cent during the three week observation period. No significant difference was observed in erythrocytic indices viz., Hb, PCV, TEC in control and infected rabbits. However, erythrocyte sedimentation rate was considerably increased in the infected rabbits. A state of leucocytosis was observed in the infected rabbits, which was due to increase in the relative percentage of neutrophils and decrease in lymphocytes. There was a significant increase in blood urea nitrogen concentrations of infected rabbits from 3 to 14 DPI as compared to controls, but serum creatinine values were not significantly altered at any stage of infection. The cause of death was attributed to kidney failure and uraemia in infected rabbits. The rabbit was found to be a suitable model for the study of absidiosis.

Renal crisis occurs in systemic sclerosis patients with rapidly progressive diffuse cutaneous thickening early in their disease. SRC is characterized by malignant hypertension, hyperreninemia, azotemia, microangiopathic hemolytic anemia, and renal failure. This complication, which in the past has been almost uniformly fatal, is now successfully treated in most cases with ACE inhibitors. This therapy has improved survival, reduced requirement for dialysis, and in those on dialysis has often allowed discontinuation of this procedure 6 to 18 months later. Prompt diagnosis and early, aggressive initiation of therapy with ACE inhibitors will result in the most optimal outcome. Chronic nonrenal crisis renal insufficiency is unusual and rarely progresses to significant renal dysfunction.

Although influenza vaccination is recommended for individuals with HIV infection, there are no data indicating an increased incidence or severity of influenza in this population. We sought to describe the clinical manifestations and morbidity of influenza in HIV-infected patients. All cases of influenza occurring in HIV-infected individuals over 3 years at a large county hospital were reviewed. Forty-three cases of influenza were diagnosed. Most patients presented with typical signs and symptoms of influenza, including cough (90%), myalgias (64%), and fever (52%). Sore throat and headache occurred in less than half of patients. The mean CD4 cell count and HIV viral load in patients with influenza was 340 cells/mm(3) and 3.34 log copies/ml, respectively. No significant differences in CD4 counts or viral loads were noted in patients with pneumonia (n=7) compared with patients without pneumonia (n=36), P>0.5. Six patients were hospitalized. One patient each had encephalitis and renal failure, although the relationship to influenza was not clear. No new or unusual clinical manifestations were observed. The rate of pulmonary complications was similar to other studies in HIV-negative patients; however, the hospitalization rate was higher than commonly seen in HIV-negative individuals.

Several patients with clinical features of chronic myeloid leukemia (CML) have fusion of the TEL (ETV6) gene on 12p13 with ABL on 9q34 and express a chimeric Tel-Abl protein that contains the same portion of the Abl tyrosine kinase fused to Tel, an Ets family transcription factor, rather than Bcr. In a murine retroviral bone marrow transduction-transplantation model, a Tel (exon 1-5)-Abl fusion protein induced 2 distinct illnesses: a CML-like myeloproliferative disease very similar to that induced by Bcr-Abl but with increased latency and a novel syndrome characterized by small-bowel myeloid cell infiltration and necrosis, increased circulating endotoxin and tumor necrosis factor alpha levels, and fulminant hepatic and renal failure. Induction of both diseases required the Tel pointed homology oligomerization domain and Abl tyrosine kinase activity. Myeloid cells from mice with both diseases expressed Tel-Abl protein. CML-like disease induced by Tel-Abl and Bcr-Abl was polyclonal and originated from cells with multilineage (myeloid, erythroid, and B- and T-lymphoid) repopulating ability and the capacity to generate day-12 spleen colonies in secondary transplantations. In contrast to findings with Bcr-Abl, however, neither Tel-Abl-induced disease could be adoptively transferred to irradiated secondary recipient syngeneic mice. These results show that Tel-Abl has leukemogenic properties from distinct from those of Bcr-Abl and may act in a different bone marrow progenitor.

Compartment syndrome is a limb-threatening and occasionally life-threatening injury. It occurs whenever the tissue pressure (referred to as interstitial pressure) within a closed anatomic space is greater than the perfusion pressure. Untreated, compartment syndrome leads to tissue necrosis, permanent functional impairment and, if severe in large compartments, renal failure and death. Compartment syndrome can occur within any muscle group located in a compartment. It is most common following an event that severely damages a muscle, like a crushing or twisting injury. Mechanisms of injury that involve circumferential burns, ischemia and tourniquets can cause compartment syndrome. Motorcyclists who suffer lower-extermity injuries in accidents are a high-risk group. A tough membrane referred to as a fascia covers muscle groups, forming a compartment for the muscle. In normal circumstances, this arrangement allows the muscle to function more efficiently, but if the muscle is injured in any way, the fascia limits the amount of swelling that can occur. This in turn restricts the flow of blood through the affected region. The first compromised function within the compartment is the flow of lymph and venous blood. If there are sensory nerves running through the compartment, they will not function correctly, causing the numbness, tingling and, later, the pain associated with compartment syndrome. With more swelling, arterial flow is compromised, pain worsens and motor function is impaired. An artificial way of producing a compartment syndrome is to place a cast or splint around a damaged extermity, compressing it. This is a way emergency personnel can compromise an injury and cause long-term consequences for the patient. Recovery is achieved by surgically opening the compartment involved (a fasciotomy) and releasing the pressure. The muscle at first will swell outside the compartment, but then it recovers, swelling is reduced and normal function can be recovered. Prehospital treatment of extremity injuries that will prevent or limit compartment syndrome is immobilization, elevation and cooling. Recognition of the syndrome later in its course, as in this case, requires the EMT to remove the patient to an appropriate emergency department. Prehospital providers need to recognize that many mechanisms of injury can produce this syndrome, even those that seem relatively minor. All injured patients should be educated to seek care should the symptoms of numbness, deep pain and coolness to the distal extremity occur. This case involved a patient who, from a relatively minor mechanism of trauma, experienced an internal disruption of the muscle group controlling the thumb (thenar mass). The early swelling in the thenar compartment resulted in the patient experiencing a tingling sensation in his left thumb. In many cases, such an injury would be referred to as a "stinger" (a temporary neurological deficit due to a sudden and excessive stimulation of a neurologic plexus or junction). But this patient had more swelling in the compartment, resulting in a lack of circulation manifested by a cool extremity, poor capillary refill and decreased pulse oximetry. Luckily, this officer recognized the need for medical evaluation of what appeared to be a minor injury and was returned to duty with no permanent impairment.

An HIV-positive white man developed hypercalcaemia and renal failure 15 months after starting highly active antiretroviral therapy. Investigations showed systemic sarcoidosis affecting parotids, skin and kidneys. This presentation was thought to be a manifestation of immune reconstitution inflammatory syndrome, and the patient was successfully treated with corticosteroid therapy.

Carbamylation is a post-translational modification of proteins characterized by the binding of cyanate to amino groups, increased in renal failure. Pathophysiological consequences of carbamylation and adverse effects of carbamylated proteins on cell functions are poorly understood. We studied the influence of carbamylated albumin on polymorphonuclear neutrophil (PMN) O(2)(-) production. Carbamylated albumin significantly decreased O(2)(-) production in PMNs stimulated by type I collagen, but not by phorbol 12-myristate 13-acetate or tumor necrosis factor-alpha. This effect was related to inhibition of p(125)FAK phosphorylation. Such an alteration of neutrophil oxidative functions might explain characteristic complications of renal failure, such as increased occurrence of inflammation or infections.

Hypercalcaemia in patients with HIV infection is usually associated with specific conditions such as lymphoma and granulomatous diseases. We described a case of severe hypercalcaemia consequent to vitamin D intoxication and secondary renal failure in a HIV patient under tenofovir using. Serum creatinine and calcium returned to near normal levels after vitamin D discontinuation, saline and furosemide administration. Some aspects of the drug-induced nephropathy are discussed.

HIV-associated nephropathy (HIVAN) is almost exclusively seen in African-Americans (AA) and is rare in Caucasians. The mechanisms responsible for the predilection of HIVAN in AA are not well understood. In transgenic mouse studies, genetic background plays a vital role in the development of the HIVAN phenotype. Larger studies in humans have been initiated to study genetic polymorphisms responsible for HIVAN. As our case illustrates, HIVAN should be considered in Caucasian patients with HIV infection complicated by nephrotic syndrome and renal failure.
