Neuronal Regeneration In Denervated Muscle Following Sensory And Muscular Neurotization, Shahryar Noordin, Mahmood Ahmed, Rasham Rehman, Tashfeen Ahmad, Pervaiz Hashmi

Section of Orthopaedic Surgery

Background and Purpose: Neurotization of denervated muscles has been shown to improve muscle bulk, but the neuronal regeneration response has not been compared previously in different surgical techniques of neurotization. Thus, using a rat model of experimental skeletal muscle denervation, we studied neuronal regeneration following sensory neurotization by two methods: sensory nerve to motor branch of muscle and direct sensory nerve implantation to muscle.
Material and Methods: The lateral head of the gas-trocnemius muscle was denervated in 36 rats, of which the first 12 served as denervated controls. In the second group of 12, the sural nerve was anastomozed to …

Follow-up consisted of serial duplex ultrasonography and clinical assessment.Results: …

Embolization Of An Intracranial Arteriovenous Malformation Followed By Immediate Surgical Resection: A Case Report, Imaad Ur Rehman, Tanveer Ul Haq, Rashid Jooma, Muhammad Azeemuddin, Zafar Sajjad

Department of Radiology

Intracranial arteriovenous malformations (AVMs) are now a recognized entity because of improvements in imaging diagnosis. They are relatively uncommon but can cause serious neurological symptoms or death. We report a case of a 22- year-old man who presented with left parietal hemorrhage and on cerebral angiography was found to have a small AVM in the left middle cerebral artery (MCA) territory. Glue embolization followed by immediate surgical resection of the AVM was carried out, resulting in complete cure.

Department of Pathology and Laboratory Medicine

Objective: To assess the frequency of primary drug resistance among newly diagnosed tuberculosis cases in Karachi.
Study Design: Cross-sectional study.
Place and Duration of Study: Multicentric study involving various TB clinics and treatment centres of Karachi between April to December 2005.
Methodology: The frequency of drug resistance among new TB patients was evaluated using a non-probability convenient sampling methodology. Sputum sample was obtained from 140 newly diagnosed sputum smear-positive patients of pulmonary tuberculosis from various centres of Karachi. Sensitivities were performed by proportion method.
Results: Fifteen (11.5%) samples in 130 eligible patients showed primary resistance to one …

Primary Drug Resistance To Antituberculous Drugs In Nwfp Pakistan, Arshad Javaid, Abdul Ghafoor, Abdul Rab, Anila Basit, Zia Ullah, Shaukat Ali, Afia Zafar, Rumina Hasan

Department of Pathology and Laboratory Medicine

Objective: To assess the prevalence of Primary drug resistance to Antituberculous drugs in NWFP
Method: A cross-sectional prevalence study was undertaken to evaluate the prevalence of drug resistance among new TB patients, using a non-probability convenience sampling methodology. Sample size was calculated according to the population and WHO's estimated incidence of smear positive tuberculosis in the province/country. Sputum samples were obtained from 122 newly diagnosed patients of pulmonary tuberculosis from centres in Peshawar and Abbotabad in NWFP.
Results: Sensitivities were performed by proportion method which showed the following resistance values in 118 eligible patients: 15 (12.7 %) …

Hepatic Angiosarcoma With Metastasis To Small Intestine, Zubair Ahmad, Azizun Nisa, Romana Idrees, Khurram Minhas, Shahid Pervez, Khalid Mumtaz

Department of Pathology and Laboratory Medicine

Hepatic angiosarcomas are rare tumours with poor prognosis, with patients usually dying within 6 months. Metastases mainly occur in lymph nodes, spleen, lungs, bones and adrenals. Metastasis to small intestine is even rarer. Similarly, primary or metastatic angiosarcomas in small intestine are extremely rare, often present with recurrent gastrointestinal bleeding and anemia, and have an extremely poor prognosis. Both primary or metastatic intestinal angiosarcomas may exhibit epithelioid morphology. It may be very difficult to differentiate between primary and secondary cases in intestine and especially when the tumour exhibits epithelioid morphology.

Antibiotic Susceptibility Of Pathogens Isolated From Patients With Community-Acquired Respiratory Tract Infections In Pakistan--The Active Study, Afia Zafar, Zahid Hussain, Eale Lomama, Sophie Sibille, Seema Irfan, Erum Khan

Department of Pathology and Laboratory Medicine

BACKGROUND: Respiratory tract infections (RTIs) are amongst the most wide spread and serious infections, accounting for over 50 million deaths globally each year. In developing countries, infants under 4 years of age are at greatest risk of lower RTIs, whereas in developed countries the severity of infection and rate of mortality are greater in elderly. The objective of the survey was to determine the in vitro susceptibility of antibiotics commonly prescribed RTIs against Streptococcus pneumoniae (SP), Haemophilus influenzae (HI) and Streptococcus pyogenes, isolated from patients with community-acquired RTIs globally. This survey involved 9 countries. In this study we present the …

Effect Of Single Dose Magnesium On Arrhythmias In Patients Undergoing Coronary Artery Bypass Surgery, M Hamid, Rs Kamal, Sa Sami, F Atiq, A Shafquat, Hi Naqvi, Fazal Hameed Khan

Department of Anaesthesia

OBJECTIVE: To evaluate the safety and role of prophylactic administration of magnesium in preventing arrhythmias.
METHOD: This double blind randomized placebo controlled clinical trial was conducted at Aga Khan University Hospital on coronary artery bypass surgery patients. All patients were connected to holter monitor before induction of anaesthesia and this monitoring continued for 24 hours. Study drug containing either 2-grams of magnesium or normal saline was given after intubation. Levels of serum magnesium was checked preoperatively and then in ICU at 0, 6, 12, and 24 hours. Independent t-test and chi square test were used for analysis. Statistical significance was …
