A cross-sectional study was conducted to explore general practitioners' (GPs) knowledge regarding the major therapeutic use and adverse effects of drug(s) they prescribe. Three drugs namely tablet Montelukast Sodium, tablet Somatriptan and inhaler Fluticasone Propionate were selected from the list of drugs approved by the Ministry of Health in Pakistan. GPs who had prescribed at least one of the three were inquired about the cost, therapeutic use and one common adverse effect. For each question, one correct option and three distracting options were given. Two hundred and ninety four responses of 131 GPs were included in the final analysis. The correct options for therapeutic use and adverse effect were identified by 61.2% (n = 180) and 40.8% (n = 120) respectively. A statistically significant (p < 0.01) deficit of knowledge regarding adverse effects was observed for those GPs who identified pharmaceutical advertisements as their primary source of information for new drugs and those who were less experienced.

Congenital adrenal hyperplasia (CAH) refers to autosomal recessive diseases resulting from deficiency of enzymes involved in the production of cortisol by the adrenal glands. This study was designed to determine the frequency of suspected congenital adrenal hyperplasia patients by evaluating the laboratory data of blood 17-OHP. The study was conducted at Chemical Pathology Section of Department of Pathology at the Aga Khan University, Karachi. The basic demographic data of 2282 subjects was recorded, screened for blood 17-OHP levels from January 2007 to December 2010. A cutoff of ³ 4 ng/ml was considered as suggestive of CAH. The results showed 17-OHP levels ³ 4 ng/ml were found predominantly among infants (14.4%) and in females (18.2%).

Metaplastic breast carcinoma (MBC) is an extremely rare breast malignancy having highly aggressive clinicopathological behaviour and dismal prognosis. A 75 years old man presented with a painless lump on right side of his chest along with two additional lumps in the ipsilateral axillary and inguinal areas. Microscopic evaluation and immunohistochemistry of trucut tissue biopsies of the lumps and that of mastectomy specimen revealed a triple-negative phenotype of poorlydifferentiated metaplastic breast carcinoma with metastatic deposits to the axillary and inguinal lymph nodes. Exhaustive internet research has revealed only a few case reports of MBC in the men; thus highlighting its absolute oncological rarity.

Melanotic neuroectodermal tumour of infancy is a rare, mostly benign but locally aggressive tumour of neural crest cell origin occurring in infants. The most commonly affected anatomic site is the maxilla. Such tumours of the brain and skull are very rare. We present the case of an 8 months old baby girl whose presenting complaint was a swelling in the scalp for 6 months. She was otherwise asymptomatic. CT imaging confirmed the presence of an osteolytic tumour in the anterior parasagittal skull with dural involvement. The tumour was surgically excised enbloc. The patient has been well at 2 years follow-up without any evidence of recurrence.

Solitary spinal epidural cavernous angiomas are rare lesions, especially in paediatric age group. They are infrequently considered in the differential diagnosis of spinal epidural masses in children. We report a case of solitary epidural cavernous angioma of the thoracic spine in a child presenting with acute onset of back pain and myelopathy. Magnetic resonance imaging of the thoracic spine demonstrated a posterior epidural mass at T6-T8 levels with compression of the spinal cord. Using microsurgical technique and bipolar coagulation, total excision of the lesion was achieved. Histopathological examination confirmed the diagnosis of cavernous angioma. At the five-year follow-up, there was no recurrence of the tumour.

Dystonia is a movement disorder characterized by sustained muscle contractions, causing twisting and repetitive movements or abnormal postures of affected body parts. Here, we present a novel case of focal dystonia of a 51 years old right-handed woman who had developed difficulty in writing and performing fine motor tasks. Due to a discomfort in her right hand at use, she started using her left hand instead and noticed inconsistent mirror movements in her right hand upon use of left hand. She was treated with trihexyphenidyl which allowed her right hand to function better, though writing still remained a problem.

Isolated hepatic tuberculosis without pulmonary or bowel involvement is a diagnostic challenge and can cause considerable morbidity. A young lady from Lahore presented with fever, pain in right hypochondria, nausea and weight loss. CT scan of abdomen showed multiple small hypodense non-enhancing lesions and a heterogeneous texture of liver. Biopsy confirmed the diagnosis of hepatic tuberculosis. It was concluded a case of isolated hepatic tuberculosis without evidence of other primary sites involvement. It is important to consider tuberculosis in the differential diagnosis when suspecting lymphoproliferative or metastatic diseases in a patient with vague symptoms and abnormal hepatic texture on CT.

Primary breast sarcomas, except for phyllodes tumour, are very rare entities, accounting for < 0.1% of all malignant neoplasms. Angiosarcoma of breast is infrequent malignancy and differential diagnosis from other sarcomatous and angiomatous breast tumours holds importance. Two cases of primary angiosarcoma of breast were encountered. One involved a 32 years lady who was treated by wide local excision and six cycles of chemotherapy. The other occurred in a 54 years old lady who was treated with mastectomy, did not receive any radiation or chemotherapy and was later lost to follow-up. Neither of the patient had history of previous breast surgery, chemotherapy or radiotherapy.
