We report factors associated with severe manifestations of histoplasmosis (such as shock, respiratory failure, and death) in patients with AIDS during an outbreak. Severe disease was present in 28 of 155 patients (17.9%). The following factors were associated with severe disease: black race (odds ratio [OR], 2.8; 95% confidence interval [CI], 1.2-6.2); hemoglobin level <9.5 g/dL (OR, 2.7; 95% CI, 1.2-6.4), partial thromboplastin time >45 s (OR, 3.1; 95% CI, 1.1-9.3); alkaline phosphatase level >2.5 times normal (OR, 3.4; 95% CI, 1.3-8.7); aspartate aminotransferase level >2.5 times normal (OR, 4.2; 95% CI, 1.7-10.0); bilirubin level concentration >1.5 mg/dL (OR, 9.2; 95% CI, 2.5-34.3); creatinine concentration >2.1 mg/dL (OR, 8.3; 95% CI, 2.2-31.9); and albumin concentration <3.5 g/dL (OR, 4.6; 95% CI, 1.3-16.4). Zidovudine use was associated with decreased risk of severe disease (OR, 0.3; 95% CI, 0.1-0.7). Multivariate analysis showed that a creatinine value >2.1 mg/dL (OR, 9.5; 95% CI, 1.7-52) and an albumin value <3.5 g/dL (OR, 4.8; 95% CI, 1.0-22) were associated with an increased risk of severe disease, and zidovudine therapy remained associated with a decreased risk (OR, 0.2; 95% CI, 0.1-0.6). Findings associated with severe histoplasmosis should be recognized early and the cases managed aggressively.

The analytical processes in clinical laboratories should be considered to be non-stationary, non-ergodic and probably non-stochastic processes. Both the process mean and the process standard deviation vary. The variation can be different at different levels of concentration. This behavior is shown in five examples of different analytical systems: alkaline phosphatase on the Hitachi 911 analyzer (Roche), vitamin B12 on the Access analyzer (Beckman), prothrombin time and activated partial thromboplastin time on the STA Compact analyzer (Roche) and PO2 on the ABL 520 analyzer (Radiometer). A model is proposed to assess the status of a process. An exponentially weighted moving average and standard deviation was used to estimate process mean and standard deviation. Process means were estimated overall and for each control level. The process standard deviation was estimated in terms of within-run standard deviation. Limits were defined in accordance with state of the art- or biological variance-derived cut-offs. The examples given are real, not simulated, data. Individual control sample results were normalized to a target value and target standard deviation. The normalized values were used in the exponentially weighted algorithm. The weighting factor was based on a process time constant, which was estimated from the period between two calibration or maintenance procedures. The proposed system was compared with Westgard rules. The Westgard rules perform well, despite the underlying presumption of ergodicity. This is mainly caused by the introduction of the starting rule of 12s, which proves essential to prevent a large number of rule violations. The probability of reporting a test result with an analytical error that exceeds the total allowable error was calculated for the proposed system as well as for the Westgard rules. The proposed method performed better. The proposed algorithm was implemented in a computer program running on computers to which the analyzers were linked on-line. Each result was evaluated on-line, and a limit violation was immediately reported. The system has performed satisfactorily in our laboratory for ten analyzers for over 1 year.

Medical records of 72 dogs diagnosed with immune-mediated hemolytic anemia (IMHA) were reviewed to find risk factors for the disease, for mortality, and for thromboembolism. Coagulation data of 32 patients were evaluated for mortality or thromboembolism risk factors. Cocker Spaniels were at increased risk for IMHA (P = .012). Timing of vaccination was not associated with development of IMHA. PCV ranged from 5 to 33%, with a mean of 16 +/- 5%. Autoagglutination was present in 42% of the dogs. Platelet counts (n = 60) varied from 3,000 to 793,000/microL (mean, 160,117 +/- 133,571; median, 144,000). Thrombocytopenia (platelet count, <200,000/microL) was present in 70% of the dogs, with severe thrombocytopenia (platelet count, <50,000/microL) being present in 22%. One-step prothrombin time (OSPT) was prolonged in 28% of the dogs tested, and activated partial thromboplastin time (APTT) was prolonged in 47% of the dogs tested. Fibrin(ogen) degradation products (FDPs) were detected in 16 of 28 dogs tested (57%). Disseminated intravascular coagulation (DIC) was diagnosed in 10 of 31 (32%) dogs and was suspected in 8 dogs. Thromboemboli were found in 20 of 25 dogs given postmortem examinations. Mortality rate was 58%. Thrombocytopenia (P = .008) and serum bilirubin concentration of >5 mg/dL (P = .015) were risk factors for mortality, and hypoalbuminemia approached significance (P = .053). Severe thrombocytopenia (P = .046), serum bilirubin concentration of >5 mg/dL (P = .038), and hypoalbuminemia (P = .016) were risk factors for thromboembolism. On evaluation of continuous data, decreased platelet count (P = .057), increased bilirubin (P = .062), and decreased albumin (P = .054) approached significance for decreased survival. A higher risk for thrombosis was found with increased alkaline phosphatase (ALKP) (P = .042), increased bilirubin (P = .047), and decreased albumin (P = .012).

This study investigated the toxicity and efficacy of a 13-cis retinoic acid, carboplatin, and paclitaxel (Taxol) regimen in 18 patients with recurrent or metastatic squamous cell carcinomas (12 head and neck, 4 cervix, 1 esophagus, and 1 anus). Three patients were treated at each dose level with fenretamide (Accutane) 1 mg/kg/d orally for 14 days, carboplatin AUC of 5 mg/ml.min intravenously (IV) and paclitaxel at a dose of 135, 155, 175, 195, 205, or 225 mg/m(2) IV on day 8 every 4 weeks for 6 cycles. Fifteen evaluable patients had a total of 72 treatment cycles. There were 21 grade III or IV toxicities distributed among all the dose levels, including neutropenia, anemia, thrombocytopenia, elevated prothrombin time/partial thromboplastin time, elevated alkaline phosphatase, weight loss, alopecia, and three deaths from aspiration pneumonia and septic shock. The maximum tolerated dosage included 205 mg/m(2) paclitaxel. There was one complete response, three partial responses, and 2 stable diseases. The three partial responses were in the four patients with cervical cancer. Responses did not correlate with expression of retinoic acid receptor subtypes. Toxicity profiles and overall response rates were comparable to prior studies with similar chemotherapy regimens alone. The data support further study in a phase II trial.

Cholangiocarcinoma can be detected worldwide, but is most common in tropical areas where crowded living conditions and poor sanitation exist. This infection can demonstrate a wide spectrum of clinical presentations from no complaints to arrest. Similar to the other liver diseases, the activated partial thromboplastin time abnormality can be seen in the patients with cholangiocarcinoma. The activated partial thromboplastin times among 33 Thai hospitalized patients with cholangiocarcinoma are studied. The correlation between the activated partial thromboplastin time and the other characteristics of the patients is studied. Most characteristics of the patients show no significant correlation with activated partial thromboplastin time (p > 0.05). The only two parameters that showed significant correlation are alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (p < 0.05). Because the activated partial thromboplastin times shows significant relation to AST and ALT but not to serum bilirubin and alkaline phosphatase, this might mention that the prolonged activated partial thromboplastin time seems to relate with the process of hepatic parenchyma damage than the biliary tract obstruction. Hence, as a hypothesis, the prolonged activated partial thromboplastin time might be a useful indication for excessive parenchymal involvement in cholangiocarcinoma. However, because the total number of cases in this study is rather small, a larger study to answer this question is necessary. In addition, the more systematic evaluations are required to answer the raised hypothesis.

Mastocytosis is often associated with organ involvement and hematological disorders. Patients may also exhibit elevated levels of plasma IL-6. To gain insight into the relevance of this observation, we correlated plasma levels of IL-6 and soluble IL-6 receptor (sIL-6R) with multiple disease parameters in 29 patients with mastocytosis. Mean plasma IL-6 levels were elevated in patients compared to healthy controls (P < 0.0001). Disease category significantly correlated with plasma IL-6 levels, as did severity of bone marrow pathology, organomegaly, and extent of skin involvement. In plasma, there was a positive correlation of IL-6 to total tryptase, alkaline phosphatase, IgM, white blood cell count, prothrombin time, partial thromboplastin time, and neutrophil numbers. There was an inverse correlation to hemoglobin. sIL-6R levels were not elevated. These observations demonstrate that IL-6 is a useful surrogate marker of severity of hematologic disease and suggest that IL-6 contributes to pathology.

There are few extensive studies about clinicopathological findings of spontaneous canine babesiosis caused by a large form of the parasite found in Europe. To further characterize and describe clinicopathological findings in dogs affected with this large form of Babesia in northeastern Italy, we evaluated 23 Italian dogs with canine babesiosis by means of clinical history, physical examination, hematological, biochemical, hemostatic tests, serum electrophoresis and urinalysis. Seventeen dogs (74%) had recently traveled on a hunting trip (within 5-15 days of being presented to the clinic) to Bosnia and Herzegovina (n=7), to Croatia (n=8) and to Hungary (n=2). The duration of clinical signs ranged from 1 to 5 days prior to the arrival at the clinic. The main clinical signs were dehydration (100%), apathy (74%), anorexia or decrease appetite (70%) and fever (68%). The anemia was present in 74% of the dogs and classified as mild (35%), moderate (59%) and severe (6%). In all cases, the anemia was normocytic and normochromic. Only three dogs presented erythrocyte regeneration. Seventy percent of dogs had hemolytic anemia and 30% had non-hemolytic anemia. Sixty-nine percent of dogs showed leucopenia and 74% neutropenia. Leucocitosis, due to mature neutrophilia and lymphocytosis, was present in one dog. Activated lymphocytes were noted in 61% of dogs. In all dogs, thrombocytopenia and an elevated hyperfibrinogenemia were present. Significant prolonged activated partial thromboplastin time (aPTT) was only found in one case. In four dogs, both plasma fibrinogen/fibrin degradation products (FDPs) and D-Dimer were increased. Antithrombin (AT) was slightly decreased in 11 of the 23 dogs. In the majority of cases, mild elevation of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), creatinekinase (CK), total bilirubin and lactic acid and decrease of total iron and total iron binding capacity (TIBC) were present. In conclusion, the main clinicopathological findings were a mild to severe thrombocytopenia, a mild to moderate hemolytic anemia, neutropenia and hyperfibrinogenemia.

The aim of this study was to investigate the therapeutic effect of platonin, a cyanine photosensitizing dye as well as an inhibitor of proinflammatory cytokines, in an animal model of heat stroke. Anesthetized rats, immediately after the onset of heat stroke, were divided into two major groups and given the following: normal saline (1 mL per kg body weight) intravenously, or platonin (12.5-50 microg/mL per kg body weight) intravenously. They were exposed to ambient temperature of 43 degrees C to induce heat stroke. Another group of rats was exposed to room temperature (26 degrees C) and used as normothermic controls. Their physiologic and biochemical parameters were continuously monitored. When the vehicle-treated rats underwent heat exposure, their survival time values were found to be 18 to 22 min. Resuscitation with intravenous doses of platonin, but not normal saline, immediately at the onset of heat stroke, significantly improved survival during heat stroke (41-147 min). All heat-stressed animals displayed systemic inflammation and activated coagulation, evidenced by increased tumor necrosis factor-alpha, prothrombin time, activated partial thromboplastin time, fibrinogen degradation products, and D-dimer, and decreased platelet count and protein C. Biochemical markers evidenced cellular ischemia and injury/dysfunction: plasma levels of blood urea nitrogen, creatinine, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, and alkaline phosphatase, and striatal levels of partial pressure of oxygen, local cerebral blood flow, glycerol, glutamate, and lactate/pyruvate were all elevated during heat stroke. The systemic inflammation, hypercoagulable state, and cerebral ischemia and injury during heat stroke were all significantly suppressed by platonin. The data demonstrate that platonin therapy may resuscitate heat stroke victims by reducing circulatory shock, systemic inflammation, hypercoagulable state, and tissue ischemia and injury.

A 17-year-old girl previously in good health presented with a 2-month history of recurrent, high-grade fever; general fatigue; anorexia; a 10-kg weight loss; and multiple, painful, reddish skin lesions on the lower abdomen. Some lesions were ulcerated, with an oily yellowish brown discharge. A systemic review was unremarkable other than bleeding from the nose. Her medical and family histories were unremarkable. On examination, the patient was pale, jaundiced, and febrile (temperature of 39 degrees C). She had enlarged lymph nodes in the axillary and inguinal areas. There was moderate hepatosplenomegaly. Local skin examination revealed multiple erythematous, tender, and firm subcutaneous nodules of variable size (1-2 cm) on the lower abdomen. Some nodules were ulcerated, with oily yellowish brown discharge and overlying ecchymosis (Figures 1 and 2). Mucous membranes were free of lesions. Laboratory investigations showed pancytopenia, an elevated erythrocyte sedimentation rate (>80 mm/h), normal renal function tests, abnormal hepatic function tests (alanine aminotransferase 172 U/L, aspartate aminotransferase 229 U/L, alkaline phosphatase 725 U/L, and total bilirubin 100 mmol/L [normal range 0-18 mmol/L]), conjugated bilirubin 45 mmol/L (normal range 0-5 mmol/L), and high triglycerides 855 mg/dL (normal range 20-200 mg/dL). Prolonged prothrombin time, 26 seconds (normal range 13-16 seconds); prolonged activated partial thromboplastin time, 61 seconds (normal range 26-38 seconds); positive disseminated intravascular coagulation studies evidenced by low fibrinogen, 74 mg/dL (normal range 160-350 mg/dL); and positive fibrinogen degradation products were also noted. Throat, midstream urine, and blood culture results were negative. Serologic tests for syphilis, HIV, and hepatitis B and C viruses were negative. Epstein-Barr virus and cytomegalovirus serologic values revealed evidence of past infection. Tuberculin and Coombs tests were negative. The alpha1-antitrypsin level was normal. Antinuclear and anti-smith antibodies, rheumatoid factor, and cryoglobulins were negative. CT showed enlarged lymph nodes in the axillary and inguinal areas, bilateral small pleural effusion, moderate hepatosplenomegaly, severe fatty infiltration of the liver, and thickening of lower abdominal subcutaneous tissue. A liver biopsy showed steatohepatitis. Bone marrow aspirate and trephine were normal. A deep punch biopsy of a nodule from the right lower abdomen revealed lobular panniculitis with atypical lymphocytes and large macrophages with cytophagocytosis ("beanbag" cells) (Figures 3 and 4). Immunohistochemistry showed that these atypical cells were positive for CD3, CD8, granzyme B, and perforin, and negative for CD56. T-cell gene rearrangement studies on skin lesions revealed a monoclonal T-cell receptor (gamma-chain) gene rearrangement, supporting the diagnosis of subcutaneous panniculitis-like T-cell lymphoma. On presentation, the initial treatment included 6 U of fresh frozen plasma, 2 U of packed red blood cells, and 2 g IV fibrinogen for 3 consecutive days. The patient was started on prednisolone 60 mg orally once daily and cyclosporine A 5 mg/kg/d orally in two divided doses. The fever and other systemic symptoms and skin lesions resolved within 2 weeks after the treatment. The prednisolone dose was tapered gradually, and a maintenance dose of cyclosporine A was continued. The patient's condition remained in remission at 12-month follow-up; there was no evidence of clinical relapse.

The purpose of the present study was to assess the therapeutic effect of hypothermic retrograde jugular vein flush (HRJVF) on heatstroke. HRJVF was accomplished by infusion of 4 degrees C isotonic sodium chloride solution via the external jugular vein (1.7 mL/100 g of body weight over 5 min). Immediately after the onset of heatstroke, anesthetized rats were divided into 2 major groups and given the following: 36 degrees C or 4 degrees C isotonic sodium chloride solution, i.v. They were exposed to ambient temperature of 43 degrees C to induce heatstroke. Another group of rats was exposed to room temperature (24 degrees C) and used as normothermic controls. When the 36 degrees C saline-treated rats underwent heat exposure, their survival time values were found to be 23 to 28 min. Immediately after the onset of heatstroke, resuscitation with an i.v. dose of 4 degrees C saline significantly improved survival during heatstroke (208-252 min). All heat-stressed animals displayed systemic inflammation and activated coagulation, evidenced by increased tumor necrosis factor alpha, prothrombin time, activated partial thromboplastin time, and d-dimer, and decreased platelet count and protein C. Biochemical markers evidenced cellular ischemia and injury/dysfunction: plasma levels of blood urea nitrogen, creatinine, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, and alkaline phosphatase; and striatal levels of glycerol, glutamate, and lactate/pyruvate; dihydroxy benzoic acid, lipid peroxidation, oxidized-form glutathione reduced-form glutathione, dopamine, and serotonin were all elevated during heatstroke. Core and brain temperatures and intracranial pressure were also increased during heatstroke. In contrast, the values of mean arterial pressure, cerebral perfusion pressure, and striatal levels of local blood flow, partial pressure of oxygen, superoxide dismutase, catalase, glutathione peroxidase, and glutathions reductase activities were all significantly lower during heatstroke. The circulatory dysfunction, systemic inflammation, hypercoagulable state, and cerebral oxidative stress, ischemia, and damage during heatstroke were all significantly suppressed by HRJVF. These findings demonstrate that brain cooling caused by HRJVF therapy may resuscitate persons who had a stroke by attenuating cerebral oxidative stress, systemic inflammation, activated coagulation, and tissue ischemia/injury during heatstroke.
