Conservative oxygen supplementation during helmet continuous positive airway pressure therapy in patients with COVID-19 and respiratory failure: a pilot study.

Background: Respiratory failure is a severe complication in coronavirus disease 2019 (COVID-19) pneumonia that, in addition to oxygen therapy, may require continuous positive airway pressure (CPAP) support. It has been postulated that COVID-19 lung injury may share some features with those observed in hyperoxic acute lung injury. Thus, a correct target arterial oxygen tension ( ) during oxygen supplementation may be crucial to protect the lung from further tissue damage.

Co-infection of SARS-CoV-2 with Chlamydia or Mycoplasma pneumoniae: a case series and review of the literature.

Introduction: The novel coronavirus SARS-CoV-2 has spread all over the world causing a global pandemic and representing a great medical challenge. Nowadays, there is limited knowledge on the rate of co-infections with other respiratory pathogens, with viral co-infection being the most representative agents. Co-infection with Mycoplasma pneumoniae has been described both in adults and pediatrics whereas only two cases of Chlamydia pneumoniae have been reported in a large US study so far.

[Changes in the cardiovascular chemo-baroreceptors as a possible basis for sudden infant death (SIDS)].

A male sixty days old infant, dying suddenly, has been diagnosed as sudden infant death syndrome (SIDS). Autopsy visualized plurifocal haematic suffusions, typical for an asphyxial status. Abnormalities were not found in the conduction system, but aorticopulmonary paraganglia hyperplasia with mild inflammatory characters has been noted.

[Cancer of the uterine cervix in Togo. Epidemiological observations and anatomopathological characteristics].

Fifty consecutive cases of cervical cancer from the Afagnan Hospital in Togo have been reviewed in their clinical features, and in ten out of these and five additional ones from the year 1979 the histological specimens were reexamined. The high rate of late diagnosis was the most striking clinical data observed, while the histopathological study revealed a high quota of undifferentiated or rare patterns, very different from the types commonly observed in Europe. In spite of the very poor public health level of the population, an almost complete absence of histological signs of HPV infection in the neoplastic tissue should be remarked.

[Cervico-vaginal infection by HPV: cyto-histological morphology in the different viral strains].

One-hundred ten cervical or vaginal bioptic samples have been submitted to in-situ HPV typing with biotinylated probes. All samples had been taken from women with colposcopic findings suggesting HPV infection, and at histopathology showed koilocytosis sometimes associated with CIN or VAIN. Sixty-four samples were positive (16 for HPV 6/11 - 37 for HPV 16/18, 11 for HPV 31/35/51).
