ABSTRACT
Adamantinoma is an extremely rare primary bony neoplasm. Because of its malignant nature, accurate and early diagnosis is very important. On the other hand adamantinoma mimics many benign conditions, so it is doubly important to establish correct tissue diagnosis to avoid radical surgery with morbidities. Because of its rarity, diagnosing adamantinoma still remains difficult, even if when it occurs in classical sites. We report a case of adamantinoma of tibial shaft diaphysis in a 23 year male. In this case, because of classic clinic-radiological features, we were suspecting adamantinoma from very beginning but final diagnosis was delayed for nine months.

A retrospective, hospital based descriptive study was done to know the pathological spectrum of thoracic lesions and to correlate the radiological findings with cytological findings obtained from computed tomography guided percutaneous transthoracic fine needle aspiration of chest mass. The clinical, radiological and cytological data of 100 patients were studied who underwent CT guided FNAC from May, 2004 to May, 2007. Diagnostic accuracy of FNAC is 82%. Cytological examination showed that 51 cases were malignant and 31 cases were benign. Provisional diagnosis based on radiological findings were 50 and 32 cases of malignant and benign lesions respectively. Sensitivity and specificity, positive and negative predictive value of radiological findings in this study was 88%, 84%, 90% and 81% respectively. Post procedure complication were (a) pneumothorax in two cases and both the cases had to be hospitalized for active management (b) minimal perilesional hemorrhage and hemoptysis in three cases and (c) chest pain in six cases. CT guided FNAC is a simple and safe procedure with high diagnostic accuracy in the evaluation of focal chest lesions. Pneumothorax, perilesional hemorrhage, hemoptysis and chest pain are the usually encountered complications. Very few cases of complication require active management.

From among 428 Nepalese schoolchildren hair samples of 102 children with clinical features of tinea capitis, obtained by the sterile hairbrush method, were examined by mycological techniques. Age varied between 4-16 years. Itching was experienced by 96.1% sample subjects and hair loss by 32.4%. Of the 102, 11 (10.8%) were positive for Trichophyton violaceum (TV), 6 being from urban areas, the rest from rural areas. Amongst the 11 patients, 7 (63.6%) were girls and rest boys. Statistical associations were observed between the place of haircut and isolation of the organism (chi2 = 15.2, p <0.01). Statistical association was also present between frequency of bathing and isolation of organism. Sharing of combs was associated with the culture-positive subjects. The prevalence of tinea capitis in the urban and rural children was 2.3% and 3.0%, respectively. The only isolated organism was TV. An association of the isolation of TV was found with risk factors such as family members, sharing of combs, frequency of bathing with the organism. Hair loss was more common in the urban children. Discouragement of sharing combs, increased frequency of hair washing, and use of uncontaminated hair cutting instruments are recommended.

Among 150 students from a semi-urban school in Kathmandu (Nepal), 30 from various age groups and both sexes with symptoms suggestive of scalp ringworm, were examined clinically. Hair samples were collected for mycological examination, using the hair brush method, from 11 of the 30 children (36.7%), aged between 5 and 14 years, who were clinically diagnosed. Four of the cultured samples were positive for isolates of Trichophyton violaceum. This minor study provides evidence that tinea capitis might constitute a substantial infectious dermatological problem in Nepal. The study also indicated T. violaceum as the causative organism of tinea capitis.
