Surgical correction of bilateral ectopic ureter using the neoureterocystostomy technique / Correção cirúrgica de ureter ectópico bilateral utilizando a técnica de neoureterocistostomia

Ureteral ectopy is a rare disorder in the small animals' clinic. It is characterized as a congenital anomaly, resulting from the ducts differentiation failure during embryogenesis. In this scenario, the ureters present themselves outside the anatomical site, being inserted into the uterus, urethra, urinary vesicle neck, or vagina. The clinical signs are urinary incontinence and perivulvar dermatitis. Surgery is the accepted treatment to correct the anomaly. The surgical procedure is based on relocating the ectopic ureter and treating associated modifications. This report describes a case of intramural bilateral ureteral ectopy, corrected surgically through the neoureterocystostomy technique, making it possible to control the animal's urinary incontinence.(AU)

A ectopia ureteral é uma afecção de incidência rara na clínica de pequenos animais, sendo caracterizada como anomalia congênita resultante de falha na diferenciação dos ductos durante a embriogênese. Neste cenário, os ureteres se apresentam fora do seu local anatômico, sendo inseridos no útero, no colo da vesícula urinária, na uretra ou na vagina. Os sinais clínicos comumente apresentados são a incontinência urinária bem como a dermatite perivulvar. O tratamento de eleição para correção da anomalia é o procedimento cirúrgico, no qual a técnica de escolha é baseada na relocação do ureter ectópico e tratamento das alterações associadas. Neste contexto, o presente relato descreve um caso de ectopia ureteral bilateral intramural, corrigido cirurgicamente por meio da técnica neoureterocistostomia, o que possibilitou controle da incontinência urinária do paciente.(AU)

Hypercalcemia induced by parathyroid hormone-related peptide after treatment of squamous cell carcinoma of oral cavity.

Squamous cell carcinoma of the head and neck is a rare cause of humoral hypercalcemia of malignancy. This paraneoplastic syndrome is usually one of the presenting symptoms of the disease. We report a case of squamous cell carcinoma of the oral cavity that presumably elaborated parathyroid hormone-related peptide (PTH-rP) and caused hypercalcemia only after radiotherapy and chemotherapy.

Current and future perspective in the management of diabetes.

Diabetes mellitus has attained epidemic proportions worldwide. It is suggested that resistin (also called Fizz 3), a cysteine. rich-protein may represent a link between obesity and insulin resistance. Uncoupling proteins are candidate genes for human obesity or type 2 diabetes mellitus. Amylin has a vital role in regulating blood glucose concentration following meals. Gluco watch biographers are safe and effective device to measure glucose every 20 minutes. Islet transplantation has had a remarkable preliminary success. Protein kinase Cbeta inhibitor was shown to reduce albuminuria and decrease statement of TGFbeta and various extracellular matrix proteins in diabetic rats.

Marcadores tumorales en cáncer broncogénico / Tumor markers in bronchogenic carcinoma

Los marcadores tumorales, hasta el momento, son una de las mayores esperanzas para un diagnóstico temprano y un seguimiento terapéutico adecuado, sin embargo, los investigadores no han encontrado aún el marcador ideal con alta sensibilidad y especificidad. La presente monografía, presenta el estado actual de estas substancias en relación al cáncer broncogénico.
