Prognostic value of thoracic recurrent nerve nodal involvement in esophageal squamous cell carcinoma.

Background: The determination of a simple and reliable prognostic factor that allows identification of patients at high risk of early cancer recurrence and subsequent death after resection of esophageal carcinoma should contribute to more accurate management of patients suffering from this disease.

Study Design: The aim of this study was to assess the prognostic value of thoracic recurrent nerve nodal involvement after curative resection of esophageal squamous cell carcinoma. The prognostic importance of gender, age, tumor penetration, and extent of lymph node involvement was evaluated in 55 patients after curative resection of esophageal squamous cell carcinoma.

[Imaging of hepatic tuberculoma].

We describe a case of localized macronodular tuberculosis of the liver, the so-called hepatic tuberculoma. Liver US scan demonstrated an hypoechoic well-delineated lesion of the left liver lobe. Liver CT scan demonstrated a hypodense lesion before and after contrast enhancement.

[The morphogenesis of vaginal diaphragms. New data].

The authors have studied seventeen fetuses which were stillborn as a result of late abortion or premature labour due to cervical incompetence. The authors examined the theory that suggests that the vagina is developed from the urogenital sinus and Mullerian duct. That theory holds that it is failure of canalization of the junction of the sinus and the duct that causes transverse septum formation in the vagina.
