ABSTRACT
Background The kidneys are supplied by a single renal artery originating from abdominal aorta. However, recent literature reports great variations in renal blood supply. Hence, it becomes mandatory for the clinicians to understand the abnormality and variations in the renal vasculature. Objective To evaluate the branching pattern of renal artery and its variations. Method The study consisted of Computed Topographic images of 206 kidneys. Numbers and branching pattern of renal artery were recorded. The data was analyzed for presence or absence, source of origin and type of accessory renal artery. Result The present study revealed that 73.79% of kidneys were supplied by a single renal artery, 25.72% by double renal artery and 0.49% by triple renal artery. The hillar branching pattern was recorded in 38.83% and early branching pattern was in 34.95%. The presence of accessory renal artery was recorded in 26.21%. They were originated from abdominal aorta in 22.81% and 3.40% from main renal artery. The prevalence of superior polar artery was found in 6.79%, hilar in 10.19% and inferior polar in 9.22%. Conclusion The knowledge of variations of renal artery becomes essential for the clinician to plan the adequate surgical procedures and to avoid any vascular complication.

PURPOSE: The aim of this study was to assess inter- and intra-observer variability of arm muscle thickness measured by critical care physicians using bedside ultrasonography (USG). METHODOLOGY: This prospective study included twenty patients admitted with sepsis. Three measurements of thickness of right arm muscles of each patient using B-mode USG were taken by two critical care fellows, independently. Intra- and inter-observer reliability was tested using intraclass correlation coefficient (ICC). RESULTS: The mean 1st, 2nd, and 3rd measurements of muscle thickness recorded by observer 1 and 2 were 23.620 (±4.171) versus 23.840 (±3.849) mm, 23.235 (±3.620) versus 23.625 (±4.062) mm, and 24.125 (±4.098) versus 23.965 (±3.651) mm, respectively. The average muscle thickness measured by first and second observer was 23.660 (±3.834) mm and 23.810 (±3.674) mm, respectively. ICC for intra-observer variability for observer 1 and 2 was 0.964 (95% confidence interval [CI] 0.924-0.985) and 0.949 (95% CI 0.892-0.978), respectively. ICC for inter-observer variability was 0.995 (95% CI 0.988-0.998). CONCLUSIONS: USG is a reliable tool for assessment of arm muscle thickness by critical care physicians.

We report a rare case of intravascular papillary endothelial hyperplasia (IPEH) of the cheek. This neoplasm, known as Masson's tumor, is an unusual vascular lesion of proliferating endothelial cells. It is usually confined to the lumen of preexisting vessels or vascular malformations. The principal significance of IPEH is its resemblance to a variety of benign and malignant diseases and possible misdiagnosis as such. Achieving a correct diagnosis is essential to avoid subjecting a patient to either unnecessarily aggressive or inadequate therapy. For this reason, awareness of this lesion is very important.
ABSTRACT
Hearing loss is the most common sensory deficit in the elderly, and is becoming a severe social and health problem. Presbycusis is the result of aging which can lead to communication problems compromising the quality of life (QoL).Since the elderly population is increasing worldwide, presbycusis is showing a similar trend. This study intended to identify the impact of hearing loss in the social life of the elderly. A total of 70 elderly patients attending Nepal Medical College Teaching Hospital who were found to have sensorineural hearing loss (SNHL) on pure tone audiometry (PTA) were recruited for this study.None of the patients had used hearing aids in the past. To assess their handicap due to hearing impairment a Hearing Handicap Inventory for the Elderly (HHIE) questionnaire was used and patients were graded as: no handicap, mild to moderate handicap and significant handicap. Pure-tone averages (PTA) were calculated for the thresholds at 0.5, 1 and 2 kHz in each ear. Patients with their PTA values between 26 to 40 dBHL were interpreted as having mild SNHL, those between 41 to 55dBHL as moderate SNHL and those above 55 dBHL as severe SNHL. Out of 70 patients, 65 had some degree of handicap ranging from mild to severe. The severity of handicap was significantly associated with the degree of hearing loss in both ears.

Ear diseases are a common presentation in the ENT out-patient department. These diseases can have sequelae if not treated early which may cause increased morbidity, hearing disability and even mortality. Identifying these conditions early and treating them can reduce these unwanted sequelae. A prospective study over a period of three years was undertaken in a tertiary care hospital in Kathmandu. All children presenting with ear diseases consecutively in the ENT out-patients were included and their data was recorded in a pro forma. The data was analysed for frequency and cross-tabulated. The study included 2218 children with ear diseases among which 868 (39.1%) were pre-school and 1350 (60.9%) were school going children. The male to female ratio was 1.5:1. The most common otological problem was wax impaction (40.2%), followed by acute otitis media (AOM) with 24.3%, chronic suppurative otitis media (CSOM) with 17.7% and acute otitis externa (AOE) with 7.5% of the total cases. The other conditions were otitis media with effusion (2.8%), foreign bodies in the ear (2.3%), otomycosis (1.7%), preauricular sinus (1.1%), sensorineural hearing loss (0.8%), trauma to the ear (0.7%), keloids (0.3%), microtia (0.2%) and perichondritis (0.2%).The three year olds had the highest number of otological diseases with 9.2% of the total among the ages studied. It is felt that proper education of health care providers regarding ear diseases and also awareness in the community can prevent and reduce the disability and complications of these conditions.
