Pharmacological strategies for the management of cancer pain in developing countries.

Pain associated with cancer is often under treated especially in the developing countries where there are problems of poor economy, poor purchasing power of the citizens, absence of effective national health insurance schemes, poor manpower, fake adulterated and expired drugs, poor drug storage conditions; adverse temperature conditions combined with poor power supply which may affect drug efficacy.

Sudden onset of herpes zoster following chemotherapy for orbital lymphoma in a HIV positive patient.

We report a 38-year-old HIV positive female, who developed an acute attack of herpes zoster HZ involving the mandibular, C2, C3, C4, T1, and T2 dermatomes, 9 days after the commencement of the first cycle of chemotherapy regimen for non-Hodgkin's lymphoma NHL.
