Pathologic manifestations of bronchiolitis, constrictive bronchiolitis, cryptogenic organizing pneumonia, and diffuse panbronchiolitis.

This article reviews the histopathological findings in a variety of inflammatory bronchiolar diseases. The emphasis is on differentiating syndromes of idiopathic airflow limitation (constrictive bronchiolitis and diffuse panbronchiolitis) from cryptogenic organizing pneumonia (idiopathic bronchiolitis obliterans organizing pneumonia). The histopathological findings in each of these conditions are relatively nonspecific; therefore, it is imperative that pathological findings are correlated with clinical and roentgenographic information before a specific diagnosis is made.

Thrombosis of fetal placental vessels. A quantitative study in placentas of stillbirths.

Microscopical examination of 50 placentas of stillborn infants and 50 of normal infants (controls) was performed for detection of thrombosis in the stem fetal vessels. Fresh fibrin thrombi occurred with equal frequency in stillborns and normal infants, suggesting that these thrombi are not necessarily of pathological significance. In normal infants they might be related to clamping of the umbilical cord. In placentas of normal infants and of stillbirths with 1 day of placental retention (P.R.) organizing thrombi were rare and when occlusive they were related to avascular villi, which suggests that they were pre-mortem in origin. By contrast organizing thrombi were found in 78.5% of placentas of stillbirths with 2-7 days of P.R, where arterial occlusive thrombi were rarely associated with avascular villi. With over 7 days of P.R. they were almost fully organized. These findings suggest that most organizing thrombi in placental vessels of macerated stillbirths are probably post-mortem clots in process of organization by the still living placenta and should therefore not be attached pathological significance.

[Extrapulmonary respiratory sounds in newborns: classification and iconographic contribution].

The extra-pulmonary stridors of the newborn represent a frequent and difficult diagnosis pathology for the radiologists and the neonatologist. After an introduction about the most important anatomical dates, A. reviews the reasons of the neonatologic stridor, and emphasizes the vascular congenital anomalies, most important for a early differential diagnosis. Concluding, are reported radiologic findings of this shifty pathology.

Successful management of left main bronchial stenosis as a rare complication of pericardiectomy.

We present a rare complication of pericardiectomy and the effective management thereof. A 67-year-old female with dyspnea and upper abdominal pain was received at our department upon referral. Chest roentgenogram and cardiac catheterization preceded a diagnosis of constrictive pericarditis. Pericardiectomy was performed subordinate to median sternotomy and left anterolateral thoracotomy. Extubation was carried out on day 2 but reintubation was necessitated on the same day as a result of progressive dyspnea. Chest roentgenogram revealed an atelectasis of the left lung. Fiberoptic bronchoscopy showed left main bronchial stenosis resulting from a pulsating external structure. A postoperative computed tomogram substantiated the stenotic left main bronchus between the dilated left pulmonary artery and the thoracic descending aorta. An expandable metallic stent for the treatment of this complication was selected over other invasive procedures. Two years of follow-up reveal no complications. Accordingly, an expandable metallic stent has demonstrated its effectiveness not only on bronchial stenosis due to malignancy or tuberculosis but on benign cases such as this as well.

[Intrapartum therapy-resistant fetal bradycardia--color Doppler sonographic diagnosis of umbilical cord compression due to fetal grasping].

Fetal heart rate pathology is seen in up to 40% of complications of the umbilical cord. We report a case in which long lasting bradycardia was associated with fetal grasping of the umbilical cord. Using colour doppler, the reason for the bradycardia could be detected. After vibro-acoustic stimulation the fetus released the grasp of the umbilical cord, following by a normalisation of the fetal heart rate and a spontaneous delivery two hours later. This case report underlines the importance of colour doppler for the diagnosis of fetal heart rate pathology.
