Bone marrow examination in cases of pancytopenia.

Abstract: This study was carried to identify the causes of pancytopenia and to find out the bone marrow morphology in cases of pancytopenia. It was a cross sectional study conducted over a period of two years in the Department of Pathology, Tribhuvan University Teaching Hospital. Bone marrow aspiration smears of patients fulfilling the criteria of pancytopenia were examined. The data obtained were analyzed using measures of central tendency. One hundred and forty eight cases underwent bone marrow aspiration and it constituted 15.74% of total cases. Mean age was 30 years (range, 1-79 years). 42 cases were children (28.37%). Male: female ratio was 1.5:1. The commonest cause was hypoplastic bone marrow seen in 43 cases (29%) followed by megaloblastic anemia in 35 cases (23.64%), and hematological malignancy in 32 cases (21.62%). Erythroid hyperplasia was seen in 29 cases (19.6%) and normal bone marrow was seen in 5 cases (3.38%). There was one case each of Niemann-Pick disease and metastatic neuroblastoma in children and chronic pure red cell aplasia and leishmaniasis in adults. Acute leukemia was the commonest hematological malignancy. In children, commonest finding was hypoplastic bone marrow (38.1%) while in adults megaloblastic anemia (30.18%) was commonest finding followed by hypoplastic anemia (25.47%). In present study bone marrow examination was able to establish diagnosis in 77% of cases. Hypoplastic marrow was the commonest diagnosis, followed by megaloblastic anemia, and hematological malignancies.

Oral submucous fibrosis―a review

Abstract: Oral submucous fibrosis (OSF) affects an estimated 2.5 million people, mostly in the Indian subcontinent. Limitation of oral opening resulting in difficulty in eating is the main presenting feature. Although nutritional deficiencies and immunological processes may play a part in the pathogenesis, the available epidemiological evidence indicates that chewing betel quid (containing areca nut, tobacco, slaked lime or other species) is an important risk factor for OSF. Genetically determined susceptibility could explain why only a small fraction of those using betel quid develop the disease. In OSF there is an incidence of oral cancer of 7.6 per cent for a median 10-year follow-up period. Risk markers for malignant transformation in OSF include epithelial dysplasia, silver binding nucleolar organizer region counts, and sister-chromatid exchange frequencies; p53 tumour suppressor gene mutations may be involved in these potentially malignant changes.

Poisoning : pattern and profile of admitted cases in a hospital in central Nepal.

Abstract: An analysis of all poisoning cases admitted in medical and pediatric wards of Patan Hospital for one year (1st Jan to 31st Dec 2004) was carried out. A total of 154 cases were admitted which was 0.8% of total hospital admissions. Females outnumbered males and almost two-thirds patients were young adults (15-34 years). Seasonal variation in poisoning was observed with more cases in the summer months. Organophosphorus compounds (42%), drugs (25%), and zinc phosphide (6.5%) were common poisonings in total and in adult populations, whereas kerosene was the most frequent poisoning in pediatric age group. Paracetamol, benzodiazepines, and tricyclic antidepressants were the most frequently used drugs. The circumstances of poisoning were intentional (75%) and accidental (20%); most of the childhood poisonings were accidental in nature. The mean hospital stay for all type of poisoning was 7.5 days; whereas it was 10.2 days for organophosphorus, 2.5 days for paracetamol, and 1.5 days each for zinc phosphide and kerosene ingestion. Intensive care unit (ICU) service was required in 17% of patients; and almost 25% developed complications. Aspiration pneumonia and respiratory failure were the most frequently observed complications. Ninety four percent of admitted patients recovered completely; leaving a mortality rate of 5%.

Comparative study between tramadol and dexamethasone as an admixture to bupivacaine in supraclavicular brachial plexus block.

Abstract: This is a prospective, randomized, double blind study to evaluate the postoperative analgesia following supraclavicular brachial plexus block with Tramadol or Dexamethasone as an admixture to bupivacaine in upper extremity surgery. Total 60 patients of ASA I and II undergoing upper extremity surgery under brachial plexus block with Bupivacaine were randomly divided in to two groups; one group received Tramadol (2 mg/kg) and the other group received Dexamethasone (8 mg) as an admixture to Bupivacaine. The duration of postoperative analgesia was recorded in both groups using pain VAS score which was determined by maximum VAS score of 8-10 and when patient demands for additional analgesics. The mean duration of postoperative analgesia in the Dexamethasone group was 1028.00 minutes while in the tramadol group it was 453.17 minutes We concluded that Dexamethasone with local anaesthetic prolongs postoperative analgesia significantly than Tramadol (P<0.05) when used as admixture to local anaesthetic in brachial plexus block in upper extremity surgery.
