Case ReportsIsoniazid toxicity presenting as status epilepticus and severe metabolic acidosis.
Isoniazid (INH) is an integral component of treatment of tuberculosis. An acute overdose is potentially fatal and is characterized by the clinical triad of repetitive seizures unresponsive to the usual anticonvulsants, metabolic acidosis with a high anion gap and coma. The diagnosis of INH overdose should be considered in any patient who presents to emergency medical services (EMS) with the triad. We report a patient presenting with multiple generalised tonic clonic (GTC) convulsions with severe metabolic acidosis as a manifestation of INH toxicity.

ReviewHyponatremia and hypernatremia: disorders of water balance.
Total body water and tonicity is tightly regulated by renal action of antidiuretic hormone (ADH), reninangiotensin-aldosterone system, norepinephrine and by the thirst mechanism. Abnormalities in water balance are manifested as sodium disturbances--hyponatremia and hypernatremia. Hyponatremia ([Na+ < 136 meq/ l]) is a common abnormality in hospitalized patients and is associated with increased morbidity and mortality. ⋯ Hypematremia ([Na+] > 145 meq/l) is caused by primary water deficit (with or without Na+ loss) and commonly occurs from inadequate access to water or impaired thirst mechanism. Assessment of the clinical circumstances and urine studies help determine the etiology, while management of hypernatremia involves fluid resuscitation and avoiding neurological complications from hypernatremia or its correction. Frequent monitoring of [Na+] is of paramount importance in the treatment of sodium disorders that overcomes the limitations of prediction equations.

Role of granulocyte colony stimulating factor (G-CSF) in chemotherapy induced neutropenia.
In the past decade, there have been many clinical trials investigating the potential benefits of adjunctive therapy with colony stimulating factors (CSFs) both to ameliorate or prevent profound neutropenia and its potentially life threatening consequences. Neutropenia is the most common dose limiting side effects of cytotoxic chemotherapy. We decided to study the effect of same in our patients coming to haematology clinic. ⋯ The study demonstrates that G-CSF administration is efficacious in chemotherapy induced neutropenia by decreasing the duration of neutropenia and duration of fever.

The mobile phone industry has been one of the fastest growing industries in modern history. Today, India has million mobile phone users, and mobile phones account for 88% of all telecommunication users. The rural sector accounts for more than 25% of all wireless phone users and this proportion is bound to grow as affordability of mobile phones continues to increase. ⋯ Studies have demonstrated that usage behaviours, such as duration of usage and predominant, one-sided use of mobile phones are some of the chief risks that increase likelihood of hazards resulting from mobile phone use. This article attempts to present the basic biophysics of these devices and explain the health hazards of electromagnetic radiation exposure in terms of thermal and non-thermal effects. We also present some preventive measures that can reduce the risk of these hazards.
