Bacteremia during tonsillectomy.

OBJECTIVE: To investigate bacteremia in patients who underwent tonsillectomy with a dissection method due to chronic tonsillitis, which may lead to dramatic results in patients that have a cardiovascular infection risk. In this study, it was explored whether the tonsil surface and the tonsil tissue interior microorganisms are different or not, and whether these microorganisms carry bacteremia development risk. METHODS: Forty patients were enrolled in the study in ENT Clinic, Firat University. A bacteriological research was performed on patients with no treatment with antibiotics for a month before the operation. Tonsil surface and deep tissue cultures were performed, and venous blood samples were taken for cultures before and after the operation. RESULTS: Surface and deep tissue cultures of tonsils of the cases represented a different result in 27.5% of the patients. No reproduction was observed regarding the blood cultures taken before tonsillectomy. Bacteremia was found in blood samples of ten patients (25%) taken immediately after tonsillectomy. CONCLUSION: Hence, it has been concluded that different microorganisms may be present among the tonsil surface and tonsil deep tissue cultures and that bacteremia may develop after tonsillectomy. Therefore, to prevent the possible dramatic outcomes after tonsillectomy the required measures during the preoperative period should be taken into consideration, especially in patients that have chronic tonsillitis with cardiovascular disease.

Leeches in the larynx.

This is a report of four patients who inhaled leeches. They presented with severe attacks of inspiratory stridor, difficulty in breathing and spitting blood. Indirect laryngoscopy revealed a dark greenish living foreign body in the larynx in each case. Laryngoscopy was performed with local anaesthesia in two of the cases and general anaesthesia was used in the other two. The leeches were removed with forceps.

Role of free oxygen radicals in noise-related hearing impairment.

This study was aimed at defining the relationship between noise-related hearing impairment in industrial workers exposed to continuous noise. For this malondialdehyde and glutathione peroxidase were analyzed as free radical form and antioxidant form. A total of 60 patients working in the units of a hydroelectric power plant were included in the study. This experimental group was further divided into three subgroups of 20 workers, each group exposed to a different noise level. The control group consisted of 20 male volunteers employed in the Medical Centre where the study was carried out. A standard ascending/descending method was applied to the subjects of the experimental and the control groups in order to determine their hearing thresholds at seven different frequencies between 250 and 8000 Hz. Then, 10 ml blood was collected from each person to measure the malondialdehyde values in plasma and glutathione peroxidase activity in erythrocytes. Slight sensorineural hearing impairment was found in group I beginning at 4 kHz and in group II beginning at 6 kHz. Statistically significant differences were observed in group I and II when compared to the control group (P<0.05). It was found that malondialdehyde levels increased in the experimental groups more than in the control groups. However, this increase was only significant in group I (P<0.05). Erythrocyte glutathione peroxidase activity significantly increased in group I and II compared to the other groups (P<0.05), also, the difference was significant between group I and II (P<0.05). Accordingly, it is suggested that free oxygen radicals may take a role in noise-related hearing impairment.

Effects of interferon-alpha-2b and octreotide on healing of esophageal corrosive burns.

OBJECTIVE: The aim of this study was to investigate the effect of interferon-alpha to 2b and octreotide on the treatment of esophagus corrosive burns. METHOD: The experimental study was performed on 63 rabbits. Burn was obtained by treating a segment, isolated in cervical esophagus, with NAOH. The rabbits were allocated into three groups (control, interferon, and octreotide). On the fourth, eighth, and 20th days, 7 rabbits randomly selected from each group were killed. Comparisons among the groups were made by taking histopathologic findings, stenosis index, and hydroxyproline production into consideration. Cross-tabulation and analysis of variance tests were used for statistical analysis. RESULTS: There were no statistically significant differences among the groups in terms of epithelial changes, extension of inflammation, and severity of fibrosis. In terms of severity of inflammation, there was a statistically significant difference between the control and the other two groups. Also, a significant difference was found between the control group and the other two groups in terms of extension of fibrosis on the 20th day. The difference between the control and the two treatment groups was significant on the eighth day and the 20th day measurements. Comparison of the hydroxyproline values showed a statistically significant difference between the octreotide group and the other two groups on the eighth and 20th days. CONCLUSION: Histopathologic and biochemical findings indicate that, by hindering fibrosis progress, octreotide (and interferon) might be new and promising alternatives in the treatment of corrosive burns of the esophagus.
