Isotretinoin in India: A tragedy in the offing

Isotretinoin in India: A tragedy in the offing Wednesday, March 28, 2007 08:00 IST  Seema Thakral Isotretinoin is the drug of choice for severe calcitrant cystic acne vulgaris, which often causes scarring and depression from disfigurement. Isotretinoin has been called "the greatest medical advance of the 1980's." A majority of patients with acne are permanently cleared after a four to five months course of treatment. It has also been used off-label for a variety of oncology uses including: cervical cancer, head and neck cancer, squamous cell cancer of the skin, juvenile chronic myelogenous leukemia (CML), and neuroblastoma. However, the drug is a proved teratogen and carries a significant risk of birth defects, if it taken during pregnancy. Birth defects, which have been documented following isotretinoin exposure include abnormalities of the face, eyes, ears, skull, central nervous system, cardiovascular system, and thymus and parathyroid glands. There is an increased

The Influence of TheTourniquet on blood draw

[1] Various methods are used to obtain specimens for hematocrit determination in neonates. We evaluated arterial sampling and found this method to be acceptable. Arterial values correlated closely with simultaneously obtained venous samples. Venous blood obtained with a tourniquet had a significantly higher hematocrit than that obtained without a tourniquet. [2] Influence of tourniquet application on venous blood sampling for serum chemistry, hematological parameters, leukocyte activation and erythrocyte mechanical properties Background: Venous blood sampling is usually performed using a tourniquet to help locate and define peripheral veins to achieve successful and safe venipuncture. Despite widespread usage of tourniquets for venipuncture by medical and laboratory staff, very few are aware of the effects of tourniquet application on laboratory parameters. In addition, definitive guidelines regarding when and how to use a tourniquet for blood sampling are lacking. The aim

The Professor Who Had to Spend Half His Life to Make the Drug India Needs

Sujoy Guha has spent 37 years trying to realise Risug, a long-term use reversible male contraceptive – itself an unusual thing. It should have come to be more than a decade ago. verything is still the same. Sujoy Kumar Guha, professor emeritus at IIT-Kharagpur, wakes up around 11 am, reads the paper and thinks of what science can offer as solutions to the big problems of the day. In the evenings he runs his PhD students off their feet with constant demands, yet somehow leaves them itching to do something worthy of him. Around midnight, he takes off for a jog around the handsome campus with a leather belt wrapped around his right palm to fend off the stray dogs. He is still the slight, sprightly, soft-spoken man he was. He still answers questions after a few seconds' silence with a lateral anecdote. He still describes most persons as a "very nice man". Everything is much the same as in 2002, when the then health minister C.P. Thakur had  announced the immine
