Modulation of signal transduction gene expression following pulsed radiofrequency in dorsal root ganglia and pregabalin therapy.

A randomized controlled study was conducted to assess modulation of signal transduction genes (, and ) following integrated multimodal approach encompassing pulsed radiofrequency treatment (PRF) of dorsal root ganglion and pregabalin in thoracic postherpetic neuralgia (PHN). Clinical variables such as pain intensity and quality of life were also explored.  A total of 40 Patients of PHN were recruited.

Fatal disseminated cryptococcosis in a HIV negative elderly Indian woman--an early diagnosis by polarizing microscopy.

An elderly HIV negative woman with disseminated cryptococcosis is reported. The clinical presentation was unusual. Rapid diagnosis is possible if Maltese crosses are demonstrated on polarizing microscopy of tissue sections or smears.
