    Purpose: to evaluate the relationdhip between preservation of the intercostobrachial nerve and pain sensitivity of the arm, total time of the surgery, and number of dissected nodes in patients submitted to axillary lymphadenectomy due to breast cancer. Methods: an intervention, prospective, randomized and double-blind study was performed on 85 patients assisted at the State University of Campinas, Brazil, from January 1999 to July 2000. The patients were divided into two groups, according to the intention of preserving or not the intercostobrachial nerve. The surgeries were performed by the same researchers, utilizing the same technique. The postoperative evaluations were performed within 2 days, 40 days and after 3 months. The pain sensitivity of the arm was evaluated through a specific questionnaire (subjective evaluation) and through a neurological physical examination (objective evaluation). Results: the surgical technique was applied to all patients and the preservation of the intercostobrachial nerve was related to a significant decrease in the alterations of pain sensitivity of the arm, both by the subjective and objective evaluations. After three months, in the subjective evaluation, 61% of the patients were asymptomatic in the intercostobrachial nerve preservation group and 28.6% in the nerve section group (p<0.01). By the objective evaluation, 53.7% of the patients presented normal neurological examination in the intercostobrachial nerve preservation group and 16.7% in the nerve section group (p<0.01). No significant difference was observed regarding total time of surgery (p=0.76) and number of dissected nodes between the two evaluated groups (p=0.59). Conclusions: these data show that the preservation of the intercostobrachial nerve is feasible and leads to a significant decrease in the alterations of pain sensitivity of the arm, without interfering in the total time of surgery and the number of dissected nodes.

    Portopulmonary Hypertension and Pregnancy

    The severity of the association of pulmonary hypertension with pregnancy is well known. Pulmonary arterial hypertension constitutes one of the highest risk conditions for maternal mortality in late pregnancy and postpartum. Patients with portal hypertension of varying etiology may develop pulmonary arterial hypertension (portopulmonary hypertension) and most cases present cirrhosis as the underlying disease; however, a few cases of noncirrhotic etiology have been described. Clinical and pathological findings in two cases of portopulmonary hypertension and pregnancy are presented here. The two patients (30 and 24 years old) developed severe right heart failure and shock just after the delivery and the disease progressed rapidly to death. Autopsy demonstrated fibrosis in hepatic portal tracts, as has been described in cases of idiopathic portal hypertension. Also, pulmonary hypertension classified as plexogenic was reported.

    Purpose: to develop a mathematical model based on the fetal heart rate (FHR) monitoring to predict metabolic acidosis at birth (base excess < -10 mEq/L), in pregnancies with absent or reversed end-diastolic velocity (AREDV) in the umbilical arteries. Methods: the last FHR tracing of 127 AREDV cases was studied by visual analysis. The analyzed parameters included: gestational age, interval between AREDV diagnosis and delivery, FHR variability, FHR accelerations, decelerations, and sinusoidal- like pattern. Multivariate logistic regression was applied to find the best mathematical model to predict acidosis. Results: metabolic acidosis at birth occurred in 51 cases (40.2%). The model included the parameters: interval between AREDV diagnosis and delivery (X1), gestational age in weeks (X2), FHR variability <5 bpm (X3), and FHR variability 5-9 bpm (X4). To each variability parameter was assigned the value of 1 when present or 0 when absent. The z value is: z = 2.2348 + (-0.0117 X1) + (-0.09 X2) + (1.9552 X3)+ (-0.4474 X4). By applying the expression p=e z/(1 + e z), the probability is estimated. Conclusion: the mathematical model allowed us to estimate the probability of metabolic acidosis at birth, in pregnancies with AREDV, studying FHR-monitoring parameters.
