Goldsmith and Karotkin' researched the history of assisted ventilation and found that a record of mouth to mouth methods goes back to Old Testament times, and Hippocrates himself reported his experience with tracheal intubation to support pulmonary function. These skills were ignored for about 2000 years as it was not until the 16th century that attention was again paid to this subject when bel...

numerous granules usually indicated normal surfactant and their absence a lack. It is concluded that the granules represent surfactant material. Osmiophilic granules were found first at 20 weeks' gestation (in 2 out of 6 fetuses). After 24 weeks' gestation almost all infants had many granules, except those with HMD. The earliest stages in hyaline membrane formation consisted of interstitial oed...

The plasmalemma and hyaline ectoplasm together constitute the sensory and motor organ of macrophages. The purpose of this study was to isolate this cell fraction in order to analyze it biochemically and functionally. Brief sonification of warmed rabbit lung macrophages caused release of heterodisperse hyaline blebs and filopodia, which were easily collected by differential centrifugation. Viewe...

Pneumomediastinum is a rare complication of ARDS but more common during #COVID19. The fibrous hyaline degeneration the tracheal rings seen in this autoptic series an original observation that has not been previously described COVID-19 patients.https://bit.ly/3vxTQde

purpose : primary localized amyloidosis of eyelid is a localized type of amyloidosis without evidence of systemic involvement, which is a quite rare clinical condition. here we report a case of primary localized amyloidosis of eyelid. case report : a 40-year-old woman presented with a four-month history of swelling of the left upper eyelid resulting in a mechanical ptosis. the mass had a firm b...

Forty-nine biopsies of bulbar conjunctiva from patients with no apparent conjunctival disease were studied by light and transmission electron microscopy. No significant morphological changes were recorded in those specimens from patients less than 79 years old. However, in the older age group the epithelium showed irregularities in thickness, a reduction in the goblet cell population, and in 25...

Castleman's disease (CD) (angiofollicular lymph node hyperplasia) was first described in 1936 (1). It is a rare disease of unknown aetiology affecting the lymph nodes. CD consists of two basic histological types: hyaline-vascular (HV) and plasma-cell (PC), and a mixed type called hyaline-vascular plasma cell type (HV-CV) (2). Clinically, it presents as an indolent disease confined to a single s...

143 fresh blood transfusions were given to 32 low birthweight babies, 28 of whom had hyaline membrane disease. The arterial or central venous pressure was raised by a blood transfusion if before transfusion the mean arterial pressure was less than 35 mmHg or if the diastolic central venous pressure was less than -- 0-5 mmHg. There was no effect of blood transfusion on pH. It therefore appears e...
