Publication Clinical, MRI and Arthroscopic Correlation in Internal Derangement of Knee(Kathmandu University, 2011) Sharma, UK; Shrestha, BK; Rijal, S; Bijukachhe, B; Barakoti, R; Banskota, B; Pradhan, I; Banskota, AKABSTRACT Background The traumatic or degenerative internal derangement of the knee requires certain investigations for the establishment of diagnosis, in addition to clinical history and a thorough physical examination. The use of arthrography and arthroscopy improves the accuracy of the diagnosis. MRI scanning of the knee joint has often been regarded as the noninvasive alternative to diagnostic arthroscopy. Objective The purpose of the study was to correlate clinical and low field MRI findings with arthroscopy in internal derangement of the knee. Methods Forty one patients with suspected internal derangement of the knee were subjected to MR examination followed by arthroscopy. Clinical criteria used were history, mode of injury, Mc Murray’s, Apley’s grinding, Thessaly’s test for meniscal injury. Drawer test was considered to be essential for clinical diagnosis of cruciate ligament injury. MRI of the knee was performed in low field open magnet (0.35T, Magnetom C, Seimens). Arthroscopy was done within two months of MR examination and was considered gold standard for the internal derangement of the knee. Results The sensitivity, specificity, diagnostic accuracy of clinical examination were 96.1%, 33.3% and 73.1% respectively for medial meniscal tear; 38.4%, 96.4% and 78.1% respectively for lateral meniscal tear. The sensitivity, specificity, diagnostic accuracy of MRI were 92.3%,100% and 95.1% for medial meniscal tear; 84.6%96.4% and 92.6% respectively for lateral meniscal tear. Conclusion Clinical examination showed higher sensitivity for medial meniscal tear compared to MRI, however with low specificity and diagnostic accuracy. Low field MRI showed high sensitivity, specificity, diagnostic accuracy for meniscal and cruciate ligament injury, in addition to associated derangement like articular cartilage damage, synovial thickening.

This study was carried out to establish the pattern of various types of cerebrovascular accident (CVA) in eastern Nepal and to correlate the clinical data and radiological findings in cases of stroke. Materials and methods: All the patients clinically diagnosed as stroke and referred to the radiology department for Computed tomography (CT) of the brain over a period of 1 year were included. Results: There were 150 patients with stroke (104 males and 46 females), aged 7 to 91 years in which infarction (58%) was more common than haemorrhage (42%) in both group of age (≤ 40 years and > 40 years). Smoking was the commonest risk factor noted in 40.66% cases followed by hypertension (40%). Excessive meat consumption (more than 4 times a week) was seen in 69.1% cases. In early Middle Cerebral Artery (MCA) territory infarction presenting within six hours of onset, positive CT findings were seen in 40% cases among which, obscuration of the lentiform nuclei was diagnostic. Conclusion: In this part of Nepal, infarction is more common than haemorrhage as the cause of stroke and in contrary to western population; hemorrhagic stroke constitutes a significantly higher proportion of stroke. Smoking is the commonest risk factor followed by hypertension and it is also seen in combination with alcohol in many cases. Excessive meat consumption could be an additional risk factor for stroke in this part of Nepal. In younger age group (≤ 40 years), haemorrhage is more common than infarction and alcohol consumption is the commonest risk factor.

Carcinoma lung is one of the tumours, which may metastasize to the thyroid. We report a 60-year-old lady with intrathyroid metastasis presenting as a solitary thyroid nodule. Fine needle aspiration cytology from the nodule showed features of metastatic adenocarcinoma. Further detail evaluation revealed primary lung adenocarcinoma with secondaries to adrenals, retroperitoneal and bilateral axillary nodes. This report emphasizes this unusual clinical presentation of carcinoma lung with wide spread secondaries; and a solitary thyroid nodule can be a presenting complain of a metastatic disease.

All the foreign bodies when left for long act as a nidus for calculus formation. The patient usually presents with dysuria, intermittent urinary tract infection or suprapubic pain. Here we report two cases of vesical foreign body which was removed by the cystoscopy.

As there is no data available on renal cell carcinoma in Nepal, hence this study was undertaken to analyze the patterns of renal cell carcinoma in patients with renal mass at a tertiary level hospital in Nepal. Objectives To analyze the patterns of renal cell carcinoma in patients with renal mass at a tertiary level hospital in Nepal. Methods The case records of 50 consecutive patients with renal cell carcinoma presenting at the Tribhuvan University Teaching Hospital, Kathmandu from July 2006 to June 2011 were retrospectively evaluated for presenting symptoms, physical finding, investigation and histopathology report. Results Out of 50 patients, 64% were male and 36% were female. The age ranged between 11 to 78 years (mean ± SD: 55 ± 15 years). Fifty four percent of patients were smokers. Incidentally tumor was detected in 40% cases by ultrasonography and the typical triad was present in only 4%. The tumor was occupying upper pole in 40% of cases. The tumor size ranged from 3 to 15 cm (mean ± SD: 7.3 ± 2.9 cm). Histopathologically, 76% of the patient had organ confined renal cell carcinoma (T1- 2 N0 M0). Clear cell was the most common type seen in 86%. Fuhrman’s nuclear grade 2 was found in 50%. Conclusion Many of the renal cell carcinoma are detected incidentally, at an early stage and are of clear cell subtype. KEY WORDS Incidental renal tumor, Nepal, Renal cell carcinoma.
