Carbon dioxide (CO2) exposure was found to result in production of pulmonary hyaline membranes in rodents by a number of investigators (1-3). In previous studies with Niemoeller (4), we were able to show that incidence of hyaline membrane formation progressively decreases in guinea pigs during prolonged exposure to CO2 after compensation of the respiratory acidosis, suggesting a nonspecific aci...

Marrow stimulation is frequently employed to treat focal chondral defects of the knee. However, marrow stimulation typically results in fibrocartilage repair tissue rather than healthy hyaline cartilage, which, over time, predisposes the repair to failure. Recently, a cryopreserved viable chondral allograft was developed to augment marrow stimulation. The chondral allograft is comprised of nati...

Sir, Castleman’s disease, also known as Angiofollicular lymphnode hyperplasia is a rare disorder of lymphoreticular system with heterogenous clinical manifestations.1 Histopathologically, it has two variants1 hyaline vascular variant and plasma cell variant. While hyaline vascular variant usually present with localized yet marked lymphadenopathy2 with few constitutional symptoms, lymphoreticula...

Systolic pulmonary arterial pressure was determined serially over the first 10 days of life in 33 babies with hyaline membrane disease by measuring the peak velocity of pansystolic tricuspid valve regurgitation, using Doppler ultrasound, and applying the Bernoulli equation. Results are presented in age groups 0-12, 13-36, 37-72, and 73-96 hours respectively. The incidence of tricuspid valve reg...

Broad ligament leiomyomas are uncommon but when they occur can present in varying degrees of bladder and bowel obstruction. A definite diagnosis the broad leiomyoma was made after histopathological report specimen obtained operating patient. 45 years old female had a history pain abdomen increase abdominal girth for 6 months. On basis CT scan left adnexal mass made. She advised surgery subseque...

A 52-year-old otherwise healthy woman presented with a solitary firm mass in the right breast. Histopathological evaluation of the 1.5-cm mass showed a mammary myofibroblastoma of the conventional spindle-cell type. High-power examination of hematoxylin-eosin-stained sections showed round, eosinophilic, intracytoplasmic, as well as extracellular, hyaline globules. These 5- to 20-µm globules app...

Many laboratories have found that their procedure for determining lecithin/sphingomyelin (L/S)ratios gives an unacceptably high proportion of false predictions of fetal lung immaturity. We investigated each step in the procedure, in an attempt to improve the clinical performance of the test and to make the method more amenable to standardization between laboratories. L/S ratios were determined ...

19 small for gestational age (SGA) infants with gestational ages less than or equal to 32 weeks were matched with 19 appropriate for gestational age (AGA) preterm neonates with similar risk factors for intraventricular haemorrhage and hyaline membrane disease. Gestational age, 1- and 5-minute Apgar scores, type of delivery, survival rate, use of corticosteroids before delivery, sex, twinning, p...

OBJECTIVE To evaluate the effect that maintaining tracheobronchial sputum at room temperature has on the analysis of ciliary transport and cough, as well as on the contact angle. METHODS Hyaline sputum was collected from 30 individuals without pulmonary diseases, and purulent sputum was collected from patients with bronchiectasis. The samples were analyzed immediately after collection and aga...
