Late postpartum preeclampsia with posterior reversible encephalopathy syndrome.

Posterior reversible encephalopathy syndrome is a reversible syndrome characterized by headache, seizures, altered mentation, and loss of vision associated with white matter changes on imaging. We report here a 27 year-old lady three weeks postpartum, presenting with posterior reversible encephalopathy syndrome. She was treated successfully with antihypertensives and showed dramatic improvement. This condition is important to recognize and needs to be treated promptly to prevent morbidity and mortality in pregnancy and postpartum.

False-positive widal in melioidosis.

Enteric fever is endemic in this part of the world, and Widal test is one of the time-honored laboratory tests that are being used for years to diagnose the disease. On the other hand, melioidosis is a newly emerging disease from this region, which is most often misdiagnosed or underdiagnosed by clinicians. It is well accepted that false-positive Widal reactions following certain non-typhoid Salmonella infections may occur commonly. Three cases of high titers of Widal test are described, where melioidosis was the actual diagnosis in every occasion and was never suspected until diagnosed microbiologically. All the patients had shown a partial response to ceftriaxone. Blood and pus cultures grew Burkholderia pseudomallei, whereas Salmonella typhi was not isolated from blood in any patient. With appropriate antibiotics, the patients showed clinical and microbiological improvement with lowering of Widal titers. These 3 cases show that high Widal titer in any patient may mislead the diagnosis of melioidosis, and further laboratory workup should always be done to rule out melioidosis, especially in cases with nonresponsiveness to treatment.

Disseminated tuberculosis presenting as mesenteric and cerebral abscess in HIV infection: case report

Disseminated tuberculosis in HIV infection involves multiple organs. Pulmonary and lymph node involvement are the commonest form of tuberculosis in HIV infection [1, 2]. Other forms of tuberculosis in the absence of lung and lymph node involvement are rare. Various forms of abdominal [3, 4] and neurological [5, 6] tubercular involvement in HIV infection have been reported. But tuberculosis presenting simultaneously with mesenteric and brain abscess has not been reported yet. We report a case of disseminated tuberculosis presenting as mesenteric and cerebral abscess in a HIV case without involving lung and lymph nodes. Bone marrow smears and fine needle aspiration cytology (FNAC) from mesenteric lesion were positive for acid fast bacilli (AFB) and the diagnosis of tuberculosis was confirmed by positive polymerase chain reaction (PCR). He responded well to treatment with anti tubercular drugs.

Radio frequency electromagnetic radiation (RF-EMR) from GSM (0.9/1.8GHz) mobile phones induces oxidative stress and reduces sperm motility in rats

INTRODUCTION: Mobile phones have become indispensable in the daily lives of men and women around the globe. As cell phone use has become more widespread, concerns have mounted regarding the potentially harmful effects of RF-EMR from these devices. OBJECTIVE: The present study was designed to evaluate the effects of RF-EMR from mobile phones on free radical metabolism and sperm quality. MATERIALS AND METHODS: Male albino Wistar rats (10-12 weeks old) were exposed to RF-EMR from an active GSM (0.9/1.8 GHz) mobile phone for 1 hour continuously per day for 28 days. Controls were exposed to a mobile phone without a battery for the same period. The phone was kept in a cage with a wooden bottom in order to address concerns that the effects of exposure to the phone could be due to heat emitted by the phone rather than to RF-EMR alone. Animals were sacrificed 24 hours after the last exposure and tissues of interest were harvested. RESULTS: One hour of exposure to the phone did not significantly change facial temperature in either group of rats. No significant difference was observed in total sperm count between controls and RF-EMR exposed groups. However, rats exposed to RF-EMR exhibited a significantly reduced percentage of motile sperm. Moreover, RF-EMR exposure resulted in a significant increase in lipid peroxidation and low GSH content in the testis and epididymis. CONCLUSION: Given the results of the present study, we speculate that RF-EMR from mobile phones negatively affects semen quality and may impair male fertility.
