To evaluate the curative effect of one-stage posterior debridement and osteotomy parallel to the endplates for reconstruction, deformity correction, and tuberculosis control on treating the spinal tuberculosis of graded GATA III. From July of 2012 to December of 2017, there were 36 cases from the Second Hospital of Sha…

In plate tectonic theory, lithosphere that descends into the mantle has a largely derivative composition, because it is produced as a refractory residue by partial melting, and cannot be resorbed readily by the parent mantle. We suggest that lithosphere sinks through the asthenosphere, or outer mantle, and accumulates…

BACKGROUND: COVID-19 messenger RNA (mRNA) vaccination coverage among children remains low, especially among children aged 6 months to 4 years. In addition, data on vaccine effectiveness (VE) for this age group are limited. METHODS: A prospective, test-negative, case-control study was conducted between April…

Human papillomavirus (HPV) testing has been suggested for primary screening of cervical cancer. Prediction of future high-grade cervical lesions is crucial for effectiveness and cost. We performed a case control study in a retrospective cohort of women with at least two cervical smears, all but the last one being negat…

BACKGROUND: Based on a meta-analysis of 52 studies, and principally on a meta-analysis of 17 follow-up studies, it has been claimed that current-or-recent use (last use <5 years previously) of menopausal hormones causes ovarian cancer, even if the duration of use was <5 years, and that women aged about 50 years who use…

To evaluate the progression of idiopathic mitral valve prolapse (MVP), a long time follow-up study (mean 7.1 years) was performed using echocardiography in 27 cases (11 males, 16 females, mean age: 50.4 years). Morphological changes, the degree of prolapse of the mitral valve, left atrial dimension (LAD) and left ventr…

Toxocariasis is one of the most widespread and important zoonotic parasitic diseases, although neglected. Data regarding humaninfection in Portugal are almost absent. This article gives an overview of the situation of toxocariasis in Portugal over the last decade based on casuistic data. A total of 846 serum samples fr…

BACKGROUND: Sexual behavior in young people is influenced by external factors that may increase their vulnerability. OBJECTIVE: to describe sexual behavior and other indicators of sexual and reproductive health among young people (16 to 24 years) in Catalonia and to identify factors associated with sexual risk behavio…

Immediate or delayed hypersensitivity reactions to iodinated contrast media (ICM) occur in 0.5-3 % of patients receiving radiological examinations using the last generation ICM. Although the majority of the reactions are mild to moderate, severe and potentially lethal reactions may occasionally be observed. In the last…

BACKGROUND: Cardiac function and survival after the Damus-Kaye-Stansel (DKS) procedure are encouraging, but only limited data exist related to postprocedural semilunar valve function. We investigated postprocedural midterm to long-term outcomes and changes in semilunar valve function and identified risk factors of semi…

Since ancient times many different methods have been used to revive newborns. Although subject to the vagaries of fashion for 2000 years, artificial respiration has been accepted as the mainstay of neonatal resuscitation for about the last 40. Formal teaching programmes have evolved over the last 20 years. The last 10…

PURPOSE: To examine the clinical results for patients with neovascular age-related macular degeneration (nAMD) who were managed with a treat-extend-stop (TES) protocol and received 50 or more injections of anti-vascular endothelial growth factor (VEGF) agents. DESIGN: Retrospective case study. PARTICIPANTS: Data for…

PURPOSE OF THE STUDY: Appropriate management of degenerative joint disease in patients with dysplasic hips is a controversial issue. Non-surgical treatment is generally insufficient to achieve good long-term results and, in young patients, indications for total hip replacement, arthrodesis, or salvage procedures (Chiar…

OBJECTIVE: To analyze the clinical course of amniotic fluid embolism (AFE) and identify the high risk factors. METHODS: Thirty-eight cases diagnosed as AFE in Suzhou region during period of past 15 years were analyzed retrospectively. Fifteen years were divided into 5 stages with 3 years each. RESULTS: Of 38 cases, 3…

Fourteen infants aged less than 1 month presented to our institution during the last 22 years with ventricular tachycardia (VT) or accelerated ventricular rhythm and a structurally normal heart. In 2, VT was associated with long QT syndrome. Both are alive on beta-blocker therapy, 1 with an implanted pacemaker. Twelve…
