Our experience of treating adult bone lymphoma, A retrospective cross-sectional study in a tertiary care center, Aga Khan University Hospital, Karachi.

OBJECTIVE: To determine the experience at the Aga Khan University Hospital in diagnosing and treating adult patients with primary lymphoma of bone. METHODOLOGY: All patients with Primary lymphoma of bone (PLB) that were diagnosed and/or treated at Aga Khan University Hospital, Karachi from 2005 to 2019 were included as part of this study. RESULTS: There were 17 patients with PLB including 13 (76.5%) males and 4 (23.5%) females with a mean age of 44 ± 16.5 years. Nine patients were between 30-59 years of age at diagnosis. The mean follow-up time of patients was 80±46.7 months. Six patients had tumours of pelvic bone followed by tibia (5) and femur (4). Four patients had a pathological fracture at the time of presentation whereas 2 (11.8%) required surgical fixation of the pathological fracture. The stage of the tumour was based on Ann Arbor classification. Nine (52.9%) cases had Stage 1 disease, 7 (41.2%) had stage IV disease with metastasis in extra nodal tissues. As for treatment, every patient received chemotherapy whereas 5 (29.4%) received adjuvant radiotherapy. Complete remission in the size of the tumour was seen in 11 (64.7%) patients while 6 (35.3%) had partial remission. Post-treatment, 4 (23.5%) patients expired. The mean Overall Survival (OS) time was 80.18 ± 46.71months with a survival rate of 76.5. CONCLUSIONS: Primary lymphoma of the bone can be treated with medical regime and good prophylactic surgeries to avoid pathological fracture such as intramedullary nailing.

Functional outcomes and complications of total hip arthroplasty with dual mobility cup : an audit.

OBJECTIVE: To determine the functional outcomes in total hip arthroplasty with a dual mobility cup, performed in our hospital. METHODS: After receiving an exemption from the Ethics review committee of the hospital, data collection for audit was started in January 2019. Records from July 2016 to June 2018 were included. All patients who underwent total hip arthroplasty with dual mobility prosthesis without any age limit were included. A proforma was prepared to collect the required information. Data was entered and analyzed on SPSS v. 21. RESULTS: Two hundred and ten patients were included, 114 females and 96 males. Of the total, 188 patients underwent unilateral surgery while 22 had bilateral hip arthroplasty. The mean postoperative hospital stay was 5.91±3.9 days. . Mean pre-op Harris score was 33.7±7.6 and the post-op mean score was 75.9± 5.34. Eighty-three (39.5 %) patients had the neck of femur fracture, 31(14.8%) had osteoarthritis while 28(13.3%) had avascular necrosis. Post-surgery complications included, wound infection, surgical site haematoma, NSTEMI, and only one patient reported dislocation after use of dual mobility cup. CONCLUSIONS: The dislocation rate which was the prime concern, has been reduced with the use of dual mobility implant in total hip arthroplasty patients.

Functional outcomes of modified Bristow procedure in recurrent shoulder dislocation.

The glenohumeral joint is the most mobile in humans. Of all the joints 50% of dislocations involve the shoulder, mostly young males. When the first dislocation occurs in a patient under 20 years age the risk for recurrent instability increases to 90%. Many techniques are available to reduce and stabilise the glenohumeral joint; in cases of anterior dislocations one of which is the famous Bristow's procedure, originally described in 1954 by Laterjet. The purpose of this study is was to determine the Functional Outcomes of the modified Bristow procedure. This retrospective review was conducted at Aga Khan University Hospital, Karachi from January 2000- December 2015, comprising patients who underwent the modified Bristow procedure. All patients recruited in the study underwent modified Bristow procedure. A total of 70 patients were included, which comprised of 61(87.1%) males and 9(12.9%) females with a mean age of 31.6±11.0 years The maximum number of shoulder dislocations occurred primarily due to road traffic accidents in 48 (68.57%) patients while the second highest cause in 13 (18.57) patients was due to playing sports. The mean number of dislocations before surgery were 3.50±0.5 whereas no patient had an episode of dislocation in the post-operative period. Two patients presented with subluxations but none required further surgical intervention. The Modified Bristow-Latarjet procedure is considered an effective surgical treatment for the recurrent glenohumeral instability of the joint.

Sprengel's Deformity.

Various shoulder bone deformities have been identified in the pediatric age group, with the most common being undescended scapula. Sprengel's deformity is dysplasia and malposition of the scapula, especially in the supraspinatus portion, mainly due to abnormal descent in the embryonic period. The clavicle is shorter and has a different contour. In some patients cervical spine deformities are also noted. This is a case of 3 years old girl presented to the clinic with difficulty in abducting right shoulder and sleeping with an internal rotation of the right arm. With physical examinations and radiological investigations sprengel's deformity was diagnosed. Sprengel's deformity is a male predominant disease which almost never occurs in isolation and is usually associated with deformities in the thoracic rib cage and the cervical and thoracic vertebrae. Our patient also had hyperpigmentation along the lines of Blaschko, which has never been previously reported with Sprengel's deformity. Sprengel's may have an association with cutaneous mosacism syndrome.

Pediatric laparoscopic surgery; initial experience from Pakistan; first 100 cases in single center.

In a developing country like Pakistan, laparoscopic surgeries are not considered favourable by many, possibly because of high costs or a lack of expertise. It is an established fact that laparoscopic surgery offers better surgical treatments with a shorter hospital stay and fewer complications. The current retrospective study was conducted at a tertiary care hospital in Karachi and comprised of laparoscopy cases performed by a single surgeon from March 2012 to September of 2014. A total of 100laparoscopic surgeries were performed; mostly appendectomies 49(49%) and undescended testes (UDTs) 34(34%). Overall, there were 70(70%) male patients. The mean age of the patients was 7.1 years and standard deviation (SD) of 2. Four (4%) patients had cellulitis. Laparoscopy paediatric surgery offered advantages of fewer wound-associated complications, less incisional pain, a shorter recovery time, and improved cosmesis.
