OBJECTIVES: There is evidence suggesting that secondhand smoke (SHS) exposure is causally linked to adverse respiratory effects. We examined the relations between the exposure to SHS and radiological signs in chest high-resolution computed tomography (HRCT). METHODS: Asbestos-exposed workers (n=633) were imaged with H…

BACKGROUND: The congenital heart disease population is aging. We hypothesized that changes in rates of congenital, valvular, and noncongenital surgical operations in congenital heart patients varied with age and disease severity over the last two decades. METHODS: We performed time trend analysis using a Quebec congen…

A clinic for patients with "resistant" hypertension was established and patients were followed by one physician, nurse, and secretary. The records of 105 randomly chosen patients out of 700 were reviewed. In 86 of 105 (82%), diastolic blood pressure was controlled (less than 90 mm Hg) (group I), but in 19 patients, aft…

Vancomycin has been in clinical use as a potent antistaphylococcal antibiotic for over 30 years. Most reports of ototoxicity and nephrotoxicity have been associated with early, relatively impure, formulations of vancomycin. This paper reviews the literature concerning vancomycin ototoxocity and nephrotoxicity and the e…

BACKGROUND: Pectus deformities and atypical costal anomalies are congenital thoracic wall defects that can cause a marked cosmetic defect with attendant psychological trauma and limited physical performance. PATIENTS AND METHODS: We reviewed 43 patients with chest wall deformities, 24 (55.8%) were pectus excavatum, 13…

OBJECTIVE: To compare functional and oncologic outcomes in elderly (&#x2265;&#x2009;70&#x2009;years) and nonelderly (<&#x2009;70&#x2009;years) patients after transoral robotic surgery (TORS). METHODS: A retrospective chart review was conducted on 114 patients who underwent TORS for head and neck squamous cell carcinom…

OBJECTIVE: To analyze the effectiveness of external fixator combined with Kirschner wire (EF-KW) fixation in the treatment of oblique and comminuted distal humeral metaphyseal-diaphyseal junction (DHMDJ) fractures in children. METHODS: A clinical data of 22 children with DHMDJ fractures who met the selection criteria…

OBJECTIVE: To introduce the satellite rod technique utilized in severe spinal deformity after three-column osteotomy (3CO) and to evaluate the radiographic and clinical outcomes at 2-year follow-up, further discussing its utilization in this particular cohort. METHODS: A total of 32 (19 females and 13 males) with an a…

BACKGROUND: To explore the application and clinical efficacy of surgical approach strategies in open reduction internal fixation of closed complex tibial Pilon fractures based on axial CT scans. METHODS: This retrospective cohort study included data of 25 patients with closed complex tibial Pilon fractures treated fro…

INTRODUCTION: This is a retrospective study that evaluate the outcome of patients with extremity sarcoma between extramedullary plate and intramedullary nailing for the biological reconstruction after tumor resection. METHODS: 58 patients (40 treated with plate fixation and 18 with intramedullary nailing, IM group) wi…

BACKGROUND/AIMS: Trends in successful eradication of Helicobacter pylori using first-line triple therapy, consisting of a proton pump inhibitor, amoxicillin, and clarithromycin, have been understudied. We evaluated H. pylori eradication rates at a single center over the last 10 years and identified risk factors related…

BACKGROUND: The prevalence of workplace violence in primary care settings internationally is high; however, data about workplace violence in US primary care settings is scant. OBJECTIVE: To describe workplace violence in a US urban academic primary care center. DESIGN: Cross-sectional design. PARTICIPANTS: Internal…

BACKGROUND: Pulmonary magnetic resonance imaging (MRI) has the advantage of nonionizing radiation and multiparameter imaging of structure and function, facilitating its clinical use in a variety of pulmonary diseases. This study aimed to identify the research trends and emerging topics in pulmonary MRI by conducting a…

BACKGROUND: While first-generation articulated disc prostheses had an ideal positioning schematically as posterior as possible because of their geometrically determined center of rotation, the dogma may change for viscoelastic implants, whose center of rotation is free. Our hypothesis was to assess whether the anteropo…

Pediatric tonsillectomy involves an often painful and lengthy recovery period, yet the extended recovery process is largely unknown. This article describes postoperative recovery outcomes for 121 children aged 4 to 15 (mean 6.6 years, SD = 2.3) years enrolled in 1 of 2 clinical trials of analgesia safety and efficacy a…

BACKGROUND: An increasing incidence of parapneumonic effusion and pleural empyema (PPE/PE) in children has been found in several studies published in the last decades. The aim of the study was to evaluate the incidence, etiology, clinical features, treatment strategies and outcomes of PPE/PE in children treated in a re…

Nowadays, postoperative pain control in infants and children is a big challenge. The only effective solution is a multidisciplinary work with accurate guidelines, starting from the preoperative period throughout the surgery and arriving at the postoperative period. The approach must be scientific, based on the recent s…

PURPOSE: Testicular cancer (TC) is the most common malignancy in 20 to 34-year-old men. Numerous publications have shown an increase in the incidence of testis cancer in the last 40 years with substantial differences among countries. We evaluated worldwide variations in testicular cancer incidence and compared trends i…
