Volvulus of the sigmoid colon in Brazil: a report of 230 cases.

Etiologic and physiopathologic aspects of volvulus of the sigmoid colon in Brazil are presented. It is believed that sigmoidal volvulus in Brazil is a frequent complication of megacolon caused by Chagas' disease, differing in some characteristics from volvulus found in other countries. A review of 230 cases treated between 1938 and 1974 in the Surgical Department of Hospital das Clinicas, University of Sao Paulo School of Medicine, is presented. The successive variations used to treat this disease occurred parallel to those introduced in the surgical treatment of uncomplicated megacolon. From the results, the following treatment is recommended: endoscopic emptying in cases without clinical, roentgenographic or endoscopic signs of intestinal ischemia. Laparotomy should be performed when a complicated volvulus is suspected or when it is not possible to empty the loop. When a simple volvulus is found, the loop should be untwisted and the gaseous contents siphoned off by menas of a rectal catheter. When there is necrosis of the colon, the Hartmann operation is recommended. It is important to submit patients to a definitive treatment of the megacolon soon after endoscopic emptying or surgical detorsion of the volvulus, since recurrences following these measures are frequent.

MR diagnosis of subdiaphragmatic anomalous pulmonary venous drainage in a newborn.

Our report describes a case of infradiaphragmatic total anomalous pulmonary venous return diagnosed by MR in a newborn with an interruption of the aortic arch with ventricular septum defect and anomalous pulmonary venous drainage. The severity of the congenital cardiopathy did not permit surgical treatment and the infant died soon after. Pathology confirmed the MR findings. Magnetic resonance not only complements echocardiography but also can be used for patients in intensive care and can in our case avoid angiography.

Isolated fetal bilateral radial ray reduction associated with valproic acid usage.

The authors describe the first case of an isolated bilateral radial ray reduction occurring in a fetus exposed in utero to valproic acid; the diagnosis was made by ultrasound during the second trimester. This case of an isolated radial ray reduction associated with valproic acid use in pregnancy is a reminder for sonographers to carefully examine not only the cardiac and neurologic system, but also the extremities, when a fetus is exposed in utero to valproic acid.

Fetal pulse oximetry during labor of 62 patients.

The objectives of the study were to assess the ability of a fetal pulse oximeter to measure the fetal oxygen saturation (SPO2) continuously during labor and to assess the correlation between readings of fetal pulse oximetry and cord blood gases at birth. The Nellcor N-400 Fetal Oximeter was used in 62 women prospectively. The mean SPO2 was unchanged at the different stages of normal labor. 53.3 +/- 9.1 to 50.1 +/- 11.8% (n = 50). The SPO2 recorded during the pushing phase of stage II (n = 40) was correlated significantly with umbilical cord arterial pH (r = 0.55; p = 0.0002), venous pH (r = 0.63; p = 0.0001), venous PCO2 (r = 0.47; p = 0.002) and venous PO2 (r = 0.39; p = 0.01). SPO2 was also correlated with scalp pH (r = 0.52; p < 0.05; n = 21). No side effects were noted. Fetal pulse oximetry could be useful to assess fetal oxygenation during labor and at birth.

[Branhamella catarrhalis in neonatal pulmonary infectious pathology].

Bronchopulmonary infections has been described for the most part in adults. ORL and upper respiratory tract infections are encountered in children. In neonates, only conjunctivitis have been reported. In their report, the authors describes the first cases of bronchopulmonary infections due to Branhamella Catarrhalis in premature infants with respiratory distress syndrome. Three cases are described in which this bacteria has been isolated in bronchial secretions and in the culture of the nasotracheal tube. Clinical and biological features were not specific. Only orosomucoid serum level was increased. A favourable outcome was obtained by macrolides. Epidemiological survey permitted the isolation of Branhamella Catarrhalis in one of the nurse who had taken care of the neonates. Otherwise, these infections occurs in immunologically compromised hosts. Hyaline membrane disease appears most likely as an auspicious factor.
