Case ReportsEvaluation of cerebral infarction in tuberculous meningitis by diffusion weighted imaging.
Ischemic complications are known to occur in tuberculous meningitis (TBM). They are usually seen in patients with TBM having a more severe disease. Diffusion weighted imaging (DWI) provides information regarding tissue ischemia at an early stage as compared to conventional magnetic resonance imaging (MRI). ⋯ DWI demonstrates a larger area of infarction and may also be useful in the early detection of infarction. It should be used as an additional sequence along with conventional imaging in patients with TBM while they are on a follow up on anti tuberculous treatment. The information obtained by DWI may be of value in explaining the clinical condition of the patient as well as in the management and prognostication.

Vibrio necrotizing soft-tissue infection of the upper extremity: factors predictive of amputation and death.
Vibrio necrotizing soft-tissue infection (VNSTI) is characterized by rapidly progressing soft-tissue necrosis and fulminant septicemia in the at-risk host. Despite advancing antibiotic and infection control practices, VNSTI is still a highly lethal and disabling disease. By evaluating prognostic factors for fatality and major amputation in VNSTI patients, this study was intended to improve treatment strategies, reduce mortality and minimize amputations. ⋯ APACHE II or LRINEC scoring system cannot be used as a reliable tool for early detection of VNSTI. For treating such a highly lethal and disabling disease, clinical acumen remains of paramount importance regardless of the scores. Expanding purpura in these patients is considered an ominous sign and may indicate surgical intervention. A serial survey of ALT/AST or CPK levels can reflect the extent of muscle damage and help determine the optimal time of amputation. Severe hypoalbuminemia also serve as poor prognostic factors implicating a high probability of death or major amputation.
