Objective: To determine the diagnostic accuracy of magnetic resonance imaging in diagnosing bone tumorskeeping histopathological as correlation gold standard. Study Design: Descriptive cross-sectional study. Place and Duration of Study: Departments of Radiology, Orthopedics and Pathology of Pakistan Institute ofMedical Sciences, Islamabad, from Jan 2018 to Jan 2019. Methodology: All the patients who had complain of bone deformity or pain with high suspicion of neoplasticpathology involving bone and soft tissue on radiograph were included in study. Patients were first diagnosed on conventional radiography followed by magnetic resonance imaging. Magnetic resonance imaging with contrast was done on Phillips 1.5 tesla machine. T1W, T2W, STIR images, Fat suppressed, PD spair and post contrast T1W images were obtained. Positive magnetic resonance imaging findings which were noted were; marrow involvement, cortical break, soft tissue involvement, joint involvement, neurovascular bundle involvement and post contrast enhancement on T1W imaging. Then bone biopsy was performed. The removed bone was sent for histopathological examination in all cases. The histopathological reports were collected. The results were entered in structured proformas. Data was collected after the informed consent. All the data was entered and analyzed using SPSS version-23. Results: Fifty patients of both genders were recruited during our study duration. 32 (64.0%) were male while 18(36.0%) were female patients. Mean age of the patient was 54.5 ± 14.3 years with range 18 to 80 years. Among the benign tumors vertebral hemangiomas were most commonly found 5 (10.0%) followed by osteochondroma which was 4 (8.0%), while among malignant........

We evaluated 99Tc(m) nanocolloid (NC) scintigraphy as a method for identifying patients with active joint disease in a group with peripheral joint pain of varying aetiology. Fifty-nine patients with peripheral joint pain were divided into two groups: those with clinical signs of active joint inflammation and those without objective signs. Thirty-four patients clinically diagnosed as having active joint disease had a total of 117 joints (95 large and 22 small) involved. 99Tc(m) NC identified 96 (79 large and 17 small) of these joints. Twenty-five patients were negative clinically. Twenty-two of these were scan negative. The other three had a total of 11 scan positive joints. The correlation coefficient between clinical and scan findings was 0.79. There was no significant difference shown between clinical evaluation and scintigraphy (z=-1.64, P = 0.1004). 99Tc(m) NC proved to be an effective method for identifying patients with active peripheral joint disease from among a group with arthralgia.

Objective: To assess the short term clinical outcomes for a single-stent (SS) strategy versus a double-stent (DS) strategy in percutaneous coronary intervention (PCI) of distal unprotected left main coronary artery (ULMCA) lesions. Study Design: Descriptive comparative study.

Objective: To describe the technique and results of mucosectomy; A surgical technique that is easy to perform, and has a lower morbidity and complication rate as compared to standard appendectomy in cases of complicated appendicitis. Study Design: Quasi-experimental study. Place and Duration of Study: Surgical - A Unit, Ayub Teaching Hospital, in Abbottabad, from Mar 2017 to Mar 2019. Methodology: Patients included were those who presented with appendicular mass, phlegmon, recurrent appendicitis, appendicitis in uncommon locations, presence of adhesions, those cases of appendicular mass and phlegmon which was either not responding to medical treatment, or diagnosed per operatively being clinically not palpable or not seen on ultrasound. Per operative and post-operative variables were documented and analyzed. In mucosectomy, thesubserosal portion of the appendix i-emuscularis and mucosa of the appendix was dissected out from the serosa after ligation of the appendicular base, or ligation done after delivering the appendix out of the serosa. The serosa that was adherent to the surrounding gut, omentum or other viscera was left intact. Results: A total of 192 patients were included in this study, half of which underwent standard appendectomy and a mucosectomy was performed on the rest. The mean time of surgery was 30 ± 1.2min as compared to the standard appendectomy group (55min ± 3.6). More than half of the patients undergoing standard appendectomy required extension of the incision (56.2%), only 8% required so from those on whom mucosectomy was performed. Per operative hemorrhage was seen in 32.2%, however inmucosectomy group only 1%.
