Compartment 1 acidosis associated with hemorrhagic diathesis causing mortalities among racing camels in Oman.

Camels are adapted to digestion of dry rough forages for their nutrition, and sudden change to highly digestible feed during the racing season causes digestive disorders. The current study investigated the cause of death among racing dromedary camels within 3-7 days following a sudden onset of fever ≈ 41 °C, colic with tarry feces, and enlarged superficial lymph nodes. Marked leukopenia, low RBC count and thrombocytopenia, deranged liver and renal function tests, and prolonged coagulation profiles were reported. Compartment 1 fluid revealed a pH of 4.3-5.2 with absence or few ciliated protozoa and Gram-positive microbial flora. Widespread petechial to ecchymotic hemorrhages were observed in various organs including the gastrointestinal tract (compartment 3 and colon), lungs, and heart. Fibrin thrombi in arterioles, capillaries, venules, and medium-sized veins were observed especially in the pulmonary interstitium, submucosa of the large intestine (ascending colon), deep dermis, and renal cortex. Furthermore, widespread hemorrhages and necrosis were constant histopathological lesions in parenchymatous organs. Based on clinical signs, hematology, blood biochemistry, and gross and microscopical findings, the cases were diagnosed as compartment 1 acidosis associated with hemorrhagic diathesis and endotoxicosis. Finally, compartment 1 acidosis associated with hemorrhagic diathesis is a serious fatal disease on the Arabian Peninsula in racing dromedaries causing multi-organ dysfunction and coagulopathy and disseminated hemorrhages.

[Bilateral retinal detachments. Risk factors and treatment efficacy: 11 cases]. / Décollements de rétine bilatéraux. Facteurs de risques et efficacité thérapeutique: évaluation chez 11 patients.

PURPOSE: The purpose of our study was to evaluate the incidence of bilateral retinal detachments and to analyze the risk factors for it and the anatomic and functional results of treatment. METHODS: Retinal detachment can be discovered in both eyes during an initial consultation. In other cases, retinal detachment may be seen in the second eye during follow-up of the first eye. RESULTS: Bilateral retinal detachments account for 11.7% of the retinal detachments in our hospital. Many factors are involved in bilateral detachment, including myopia and degenerative lesions. Treatment depends on the type of detachment. CONCLUSION: Treatment of bilateral detachments is difficult and depends on the specific type of detachment. Relatively young men are most at risk for bilateral detachments.

Toxic epidermal necrolysis and clarithromycin.

Toxic epidermal necrolysis almost always occurs after taking a medication. Despite spectacular clinical signs, it is mainly diagnosed with pathologic techniques. The identification of a drug as the cause for the immune related cytotoxic reaction can be difficult if the molecule is not generally known to be a classical cause of this reaction. The present study describes a female patient who rapidly developed a severe bullous skin disease after taking clarithromycin for tonsillitis. The case illustrates the process involved in attributing causality to a molecule using an established imputability assessment framework.

Evaluation of three rapid detection methods for the forensic identification of seminal fluid in rape cases.

We sought to discover whether spermatozoa concentration and the delay between ejaculation and test influence the results of seminal fluid fast detection tests. Two hundred and twenty-seven anonymous samples divided into four groups (normospermia, oligospermia, azoospermia, and controls) after a semen analysis were subjected to three fast detection semen tests: Diff-Quick fast coloration, Phosphatesmo Km Paper for acid phosphatases (AP) detection, and PSA-Check 1 for prostate specific antigen (PSA) detection. The study was performed at three time points (0, 48, and 72 h). Unlike cytology, results obtained with AP and PSA were not influenced by spermatozoa concentration. PSA detection results remained constant up to 72 h and were more reliable after 48 h than those obtained by AP detection.
