RESUMO

Objective: To study fixed-dose combinations (FDC) of antibacterial and antiprotozoal products (ofloxacin and azoles), prescribed for the treatment of diarrhea. Methods: Rationality of these FDC products was verified by assessing parameters such as drug content and release by assay and dissolution tests, respectively mentioned in the Indian Pharmacopoeia (IP). Amount of drug solubilized and permeated as per the Biopharmaceutics Classification System (BCS) was determined. Ex vivo permeation study was performed on the gut of goat using the everted gut sac technique. Antimicrobial efficacy in terms of minimum inhibitory concentration (MIC) was assessed using agar well diffusion method against Shigella boydii, the causative agent for diarrhea. Comparative studies were performed on an individual as well as combination doses of antibacterial and antiprotozoal products for the synergistic effects to assess the rationale of these FDC. Results: The BCS solubility of ciprofloxacin (CPX), norfloxacin (NFX) and tinidazole (TNZ) was high in acidic medium (pH 1-5) and decreased at pH above 5. The assay studies showed that the individual drug contents of FDC were within the IP limits. In vitro dissolution results for both, individual drugs and their combination illustrated 99 % drug release within 30 min in 0.01N HCl. Ex vivo permeation of TNZ was higher than CPX and NFX in individual drugs. No significant change in the permeation rate was observed for individual drugs and their FDC. CPX and NFX exhibited more antimicrobial activity in terms of inhibitory zones than their FDC with antiprotozoal TNZ, above 2.5 µg/ml MIC. The pharmaceutical, biopharmaceutical and antimicrobial evaluation study showed the similarity of FDC with the individual drugs. Conclusion: The study showed no significant data to justify the therapeutic advantage of FDC over individual drugs.

RESUMO

Breast hamartoma has a low incidence (0.1-07%). It is a benign lesion of uncertain origin. The main concern about hamartoma is that it can present as either palpable breast lump or apparent breast mass on mammographic examination, and this naturally leads to follow up investigations to rule out possible breast malignancy. Here is a case of a clinically suspected fibroadenoma in a 35 year old female. The histopathological examination proved it to be a hamartoma.

RESUMO

Ewing sarcoma is a rare malignant round cell tumor of the bone. It is the second most common primary malignant tumor of bone found in children. It commonly affects long bones, pelvis and ribs. An 11 year old boy presented with painful swelling at the medial end of left clavicle. X-ray revealed a diaphyseal lesion of the medial end of the left clavicle with destruction of bone and mottled appearance. FNAC was done and reported as Malignant round cell tumor suggestive of Ewing sarcoma. Histopathologically the diagnosis of Ewing sarcoma was confirmed with special stains. Ewing sarcoma affecting clavicle is uncommon. Clavicle can be often resected with no need of reconstruction in young children.

RESUMO

BACKGROUND: Oral submucous fibrosis (OSF) is a precancerous condition caused by use of the areca nut. The reported prevalence of OSF in Bhavnagar district during 1967 was 0.16%. We investigated whether the impression of an increase in the incidence of the disease was real. METHODS: A house-to-house survey was conducted in Bhavnagar district, Gujarat state. The use of areca nut-containing products and tobacco was assessed through an interviewer administered questionnaire. The oral examination was done by dentists. The diagnostic criteria for OSF was the presence of palpable fibrous bands. RESULTS: A total of 11,262 men and 10,590 women aged 15 years and older were interviewed for their tobacco habits. Among 5018 men who reported the use of tobacco or areca nut, 164 were diagnosed as suffering from OSF. All but four cases were diagnosed among 1786 current areca nut users (age-adjusted relative risk: 60.6). Areca nut was used mostly in mawa, a mixture of tobacco, lime and areca nut, and 10.9% of mawa users had OSF (age-adjusted relative risk: 75.6). The disease as well as areca nut use was concentrated (about 85%) in the lower (< 35 years) age group. CONCLUSIONS: An increase in the prevalence of OSF, especially in the lower age groups, directly attributable to the use of areca nut products was observed. This could lead to an increase in the incidence of oral cancer in the future.
