Hormonal exposures and the risk of intracranial meningioma in women: a population-based case-control study

Background  

The role of exogenous hormone exposures in the development of meningioma is unclear, but these exposures have been proposed as one hypothesis to explain the over-abundance of such tumors in women.     

应用新型缝合器经腹腔镜行溃疡穿孔修补术

1995年3月。我们应用一种新型缝合器为6例消化性溃疡穿孔病人进行了囊腔镜穿孔修补术，初步经验表明，这是一种适用、易掌握和操作的器械。可显著地缩短手术时间。     

Craniofacial mucormycosis: assessment with CT

Computed tomographic (CT) scans of ten patients with rhinocerebral mucormycosis were reviewed. Early paranasal sinus involvement appeared as mucosal thickening on CT scans, usually without air/fluid levels. Recognition as mucormycosis was facilitated by knowledge of the clinical setting or by identification of invasive disease. Evidence of bone destruction on CT scans was seen in only two patients, was a late finding, and usually was absent despite deep extension of disease beyond the bony confines of the paranasal sinus. Five cases had intracranial involvement, either as fungal abscess or infarction. Intracranial mucormycosis usually involved the base of the brain and cerebellum following invasion of the infratemporal fossa or orbit. Intracerebral fungal abscess appeared as low-density masses on CT scans, with variable peripheral enhancement and little surrounding vasogenic edema. Identification of a rim of spared cortex was useful in distinguishing infection from bland infarct. Serial CT scans were also useful in assessing response to hyperbaric oxygen treatment, surgery, and chemotherapy.     

Diagnosis of congenital antral web by ultrasound

Historically, the first case of congenital prepyloric membrane in an infant was documented in 1933 [1]. Since then cases have been reported only sporadically in the literature [2–8]. This is a case of congenital antral web which was identified by real-time ultrasonography, confirmed by barium meal study, and proven at gastrotomy.     

Expanding spectrum of pulmonary disease caused by nontuberculous mycobacteria

The clinical and radiographic features of 35 patients with nontuberculous mycobacterial (NTMB) pulmonary infections were reviewed. Radiographs of half the patients showed the pattern of cavitary upper-lobe infiltrates typical of reactivation tuberculosis; those of the other half had a radiographic pattern characterized by patchy, nodular infiltrates without an upper-lobe prevalence. Approximately half of the latter group showed multiple small cavities resembling those seen in bronchiectasis. These results suggest that studies in which the diagnosis of NTMB infection has been made primarily from sputum cultures may have been biased toward detecting cavitary disease. The spectrum of pulmonary disease caused by NTMB appears to be larger than previously appreciated. An enhanced awareness of alternate presentations of NTMB infections may result in earlier diagnosis.     

Low-Temperature-Adapted Influenza A2/AA/6/60 Virus Vaccine in Man

Volunteers inoculated nasopharyngeally with liver A2/AA/6/60 virus grown in primary bovine kidney cell cultures at 25 C were asymptomatic but developed significant serum and respiratory secretory antibody responses. Viruses were not recovered from these volunteers who had a low or moderate level of prevaccination antibody titers.
