The relation between pure papillary and follicular variant in papillary thyroid carcinoma.

OBJECTIVE: Pure papillary thyroid carcinoma and the follicular variant papillary thyroid carcinoma are the most common subtypes of papillary thyroid carcinoma. The aim of this study was to investigate the effects of prognostic factors of these two subgroups in our series. PATIENTS AND METHODS: Histopathological type of carcinoma was retrospectively revised in 199 patients who were then divided according to such type. Patients' age and gender as well as the size and multicentricity of tumor, association with Hashimoto's thyroiditis, serum thyroglobulin and anti-thyroglobulin antibodies levels, metastatic lymph node and distant metastases status for both groups were evaluated. RESULTS: Gender, size, multicentricity of tumor, serum thyroglobulin and anti-thyroglobulin levels were similar in both groups. It was found that, although the tumor size of pure papillary thyroid carcinoma was smaller than that of follicular variant papillary thyroid carcinoma, lymph node metastases occurred more frequently when both subgroups were examined. CONCLUSION: The pathological and clinical signs of pure papillary thyroid carcinoma and follicular variant papillary thyroid carcinoma were found similar. According to these results, this study does not support the literature which claims that follicular variant papillary thyroid carcinoma is more aggressive than pure papillary thyroid carcinoma. Moreover, it could be assumed that the number of patients who are diagnosed as pure papillary thyroid carcinoma may be higher when associated with Hashimoto's thyroiditis.

Comparison of the effects of sodium nitroprusside and L-carnitine in experimental ischemia-reperfusion injury in rats.

AIM: The aim of this study was to evaluate the protective effect of sodium nitroprusside (SNP) as a nitric oxide (NO) donor and L-carnitine intraperitoneal administration to treat experimental ischemia-reperfusion (I/R) in rats. MATERIALS AND METHODS: Rats were divided into four groups, each one consisting of 10 animals. Group 1 was subjected to a sham operation. In group 2, an I/R process was applied to the rats. In group 3, SNP (5 mg/kg) and in group 4, L-carnitine (500 mg/kg) was administered in addition to the I/R process. Ileal tissue samples were obtained for analysis of tissue malonyl dialdehyde (MDA) and for histopathologic examination. RESULTS: By histopathologic examination, the I/R group showed a significant difference from the SNP and L-carnitine groups (P<.05). There was no difference between the sham, the SNP, and the L-carnitine groups (P>.05). SNP used as an NO donor produced a significant decrease in MDA levels. There was a significant difference between the MDA levels of the SNP and the I/R groups (P<.05). Also, the difference between this group and the I/R group was significant (P<.05). CONCLUSION: SNP helped to both prevent and reduce mucosal damage in terms of histological and tissue MDA levels. Since the results of the L-carnitine group and the SNP group were similar, L-carnitine was as effective as exogenous NO.

Effect of meloxicam on postoperative pain relief after inguinal hernia repair with local anaesthesia

Aim: To investigate the effect of the administration of a single dose of meloxicam pre-emptively on postoperative pain management in patients who underwent inguinal hernia repair under local anaesthesia. Subjects and Method: Fifty patients who underwent inguinal hernia repair under local anaesthesia during the period November 2005 to May 2006 were recruited into the study prospectively. The patients were randomized to two groups regarding administration and non-administration of pre-emptivemeloxicam. The postoperative visual analogue pain scale (VAS) values at 4, 8, 12 and 24 hours and analgesic needs of the patients were recorded. Results: No difference was found between the groups in terms of age, gender, hernia localization and type. The VAS values of the patients regarding their pain severity were evaluated at 4, 8, 12 and 24 hours and were significantly lower in the group which received meloxicam pre-emptively (p = 0.001, 0.0001, 0.003 and 0.0001 respectively). The need for non-steroidal anti- inflammatory drug was also found to be significantly lower (p = 0.0001). Conclusion: Postoperative pain severity and hence analgesic requirement were significantly decreased in the patients who received meloxicam pre-emptively. Single dose pre-emptive meloxicam seems to be an effective analgesic therapy for patients undergoing inguinal hernia repair under local anaesthesia.It thereby improves patients comfort and should be considered for use in outpatient surgery.

Objetivo: Investigar el efecto de la administración de una dosis de meloxicam de forma preventiva enel tratamiento del dolor postoperatorio en pacientes sometidos a una reparación quirúrgica de hernia inguinal bajo anestesia local. Sujetos y Métodos: Cincuenta pacientes que tuvieron una reparación de hernia inguinal bajo anestesia local durante el período de noviembre de 2005 a mayo de 2006, fueron reclutados para el estudio demodo prospectivo. Los pacientes fueron divididos aleatoriamente en dos grupos, partiendo del criterio de la administración o no administración de meloxicam de modo preventivo. Se registraron los valores de la escala visual-analógica (EVA) para el dolor postoperatoria a las 4, 8, 12 y 14 horas, así como las necesidades analgésicas de los pacientes. Resultados: No se hallaron diferencias entre los grupos en relación con la edad, el género, lalocalización y el tipo de hernia. Los valores de la EVA de los pacientes con respecto a la severidad de su dolor, fueron evaluados a las 4, 8, 12 y 24 horas, y resultaron ser significativamente más bajos en el grupo que recibió meloxicam de forma preventiva (p = 0.001, 0.0001, 0.003 y 0.0001 respectivamente). También se halló que la necesidad de un medicamento anti-inflamatorio no ester-oidal era significativamente más baja (p = 0.0001). Conclusión: La severidad del dolor postoperatorio y por lo tanto la necesidad de analgésicos, experimentaron una disminución significativa en los pacientes que recibieron meloxicam de forma preventiva. La dosis sencilla de meloxicam de forma preventiva parece ser una terapia analgésica efectiva para pacientes que han sido sometidos a reparación quirúrgica inguinal con anestesia local. Su aplicación mejora el alivio de los pacientes, y debe tenerse en cuenta su uso para la cirugía ambulatoria.

Retrorectal hemangiopericytoma: a case report.

Hemangiopericytoma is a rare, vascular soft tissue tumour originating from the pericytes, the contractile cells that surround capillaries. A case of retrorectal hemangiopericytoma in a 49-year-old woman is reported. With a posterior sagittal approach, the tumour was completely removed. Pathological examination, including immunohistological stains, was consistent with a hemangiopericytoma. A step-by-step approach to a retrorectal tumour is exemplified, and a very rare pathological entity is added to the spectrum of retrorectal masses.
