Certain arthropod-borne infections are common in tropical regions because of favorable climatic conditions. Water-borne infections like leptospirosis are common due to contamination of water especially during the monsoon floods. Infections like malaria, leptospirosis, dengue fever and typhus sometimes cause life threatening organ dysfunction and have several overlapping features. ⋯ Hence empiric therapy for more than one disorder may be justified in a small proportion of cases. In addition to specific anti-infective therapy, management of organ dysfunction includes use of mechanical ventilation, vasopressor drugs, continuous renal replacement therapy and blood products. Timely transfer of these patients to well-equipped ICUs with experience in managing these cases can considerably decrease mortality and morbidity.

Comparative StudyEfficacy of species specific anti-scorpion venom serum (AScVS) against severe, serious scorpion stings (Mesobuthus tamulus concanesis Pocock)--an experience from rural hospital in western Maharashtra.
Death caused by scorpion envenoming is a common event in the tropical and subtropical countries including many regions in India. Severe scorpion envenoming causes an autonomic storm producing multi-system organ-failure (MSOF) and death. ⋯ AScVS is effective and safe method of therapy in severe scorpion envenoming syndrome.

Practice GuidelineAPI TB Consensus Guidelines 2006: Management of pulmonary tuberculosis, extra-pulmonary tuberculosis and tuberculosis in special situations.
The World Health Organization (WHO) has declared Tuberculosis (TB) a global emergency in 1993. Prevalence of TB and Human Immunodeficiency Virus (HIV) co-infection worldwide is 0.18% and about 8% TB cases have HIV infection. Effective chemotherapy has been available for treatment of TB for over 50 years now. In World Health Organization (WHO)-International Union Against Tuberculosis and Lung Disease (IUATLD) Working Group Global Anti-Tuberculosis Drug Resistance Surveillance (1994-1997), the incidence of MDR TB in Delhi was found to be 14%, of which primary multi-drug resistance was only 1.4%, indicating that most of MDR TB is acquired as a result of poor chemotherapy. ⋯ Pregnancy: All drugs, that is, rifampicin, isoniazid, ethambutol, and pyrazinamide can be used during pregnancy. Streptomycin is not given due to ototoxicity to the fetus. Prophylactic pyridoxine in the dose of 10mg/day is recommended along with ATT. Diabetes mellitus: The drug regimen is same as in nondiabetic. Strict control of blood glucose is mandatory. Also, doses of oral hypoglycemic agents may have to be increased due to interaction with Rifampicin. Prophylactic pyridoxine is indicated. Renal failure: Dosages may have to be adjusted according to the creatinine clearance especially for streptomycin, ethambutol and isoniazid. In acute renal failure, ethambutol should be given 8 hours before hemodialysis. In post renal transplant patients: Rifampicin-containing regimens are avoided as rifampicin causes increased clearance of cyclosporin. Pre-existing liver disease: In stable disease with normal liver enzymes, all anti-tuberculous drugs may be used but frequent monitoring of liver function tests is required. Treatment in unconscious patient (patients unable to swallow): If patients are fed by Ryle's tube or gastrostomy tube, usual doses and drugs may be powdered and administered avoiding feeds 2-3 hours before and after the dose. In cases where enterostomy has been performed or parenteral nutrition is being used, intramuscular streptomycin and isoniazid and intravenous quinolones may be used and switch to oral therapy once oral feed resume. Treatment of TB with HIV co-infection: In early stages the presentations of TB in TB-HIV co-infection is the same as HIV negative but in late stages extra-pulmonary and dissemination are common. The usual short course chemotherapy is indicated in HIV positive patients. The response is usually good but relapse is frequent. After initiating ATT or anti-retroviral therapy (ART) worsening of preexisting lesions or appearance of new lesions is seen, "paradoxical response" or "immune reconstitution phenomenon". Multidrug resistant TB can occur due to poor compliance to ATT due to behavioural pattern, increased incidence of side effects and malabsorption of drugs due to associated diarrhea. ART for HIV, containing protease inhibitors (PI) and non-nucleoside reverse transcriptase inhibitors (NNRTI) cannot be used along with R, as R induces metabolism of PI and reduces the efficacy. The various options are i) to postpone anti-retroviral therapy ii) to use no PI or NNRTI containing anti-retroviral combinations iii) to use certain PI/ and/or NNRTIs with modification in doses iv) Efavirenz (EFZ) or Saquinavir with Ritonavir, without the need to adjust the doses v) to use non R regimens e.g. 2SHEZ+10HE MANAGEMENT OF MDR TB: As far as possible treatment of MDR TB should be referred to specialized units with facilities for quality controlled DST and experienced in handling such cases. If such referrals are not possible, one must remember that while initiating or revising therapy for MDR-TB, drugs selection must rely on prior treatment history, results of susceptibility testing and an evaluation of the patient's adherence.

Macrophage Activation Syndrome is a rare and potentially fatal disease, to be considered in patients with a SIRS like clinical presentation. Falling ESR and hyperferritinemia in the appropriate clinical setting can be the greatest clues. We report a case in which a female admitted with fever and rash, initially had systemic inflammatory response syndrome (SIRS) like clinical presentation, but eventually proved to be a rare case of fatal Macrophage Activation Syndrome.

Case ReportsSubarachnoid haemorrhage as a presentation of cerebral venous sinus thrombosis.
Cerebral venous sinus thrombosis can present with a variety of clinical symptoms ranging from isolated headache to deep coma. Subarachnoid haemorrhage is a rare presentation. In the report, we describe a case of non-puerperal venous thrombosis of many dural sinuses manifesting on imaging solely as localized subarachnoid haemorrhage without underlying parenchymal involvement.
