Objectives
To evaluate the utility and effectiveness of hysteroscopic retrieval of intrauterine devices (IUDs) in early pregnancy.Subjects and methods
We followed-up four pregnant women with IUDs with retracted tails removed by hysteroscopy before 10 weeks of pregnancy from 2003 to 2005.Results
After hysteroscopy, pregnancy course was successful in three women, without complications that could be attributed to the procedure. There was one abortion due to rupture of fetal membranes at 15 weeks’ gestation.Conclusions
The application of hysteroscopy in pregnancy has always been limited. In all patients, a possible optic nerve lesion in the fetus should be evaluated. This technique should not be performed after the 10th week of pregnancy. In most patients, pregnancy continues without complications after IDU removal. 相似文献44.

Background:Autonomic nervous system balance is altered in cystic fibrosis (CF), although its influence on physical fitness has been poorly explored.Objective:This study aimed to evaluate the association of heart rate variability (HRV) with exercise capacity and levels of daily physical activity in children and adolescents with mild-to-moderate CF.Methods:A cross-sectional study including individuals with CF aged 6–18 years, not under CFTR modulator therapy, was performed. Sociodemographic (age, sex) and clinical information (airway colonization, pancreatic insufficiency, and genotyping) were collected. In addition, exercise capacity (modified shuttle test — MST), lung function (spirometry), body composition (bioimpedance), levels of daily physical activity (5-day accelerometer), and HRV (both at rest and during the MST) were evaluated.Results:30 individuals (20 females) aged years, mean FEV%, were included. A sympathovagal balance (LF/HF) increase () during the MST was shown, indicating a predominance of sympathetic modulation. The standard deviation of all RR intervals (SDNN) and the high frequency (HF) index during exercise correlated significantly with FEV1 (, and , ; respectively). MST distance also correlated positively and significantly with SDNN (, ), square root of the mean of the sums of squares of frequencies between RR intervals greater than 50 ms — RMSSD (, ), low frequency — LF (, ), HF (, ), dispersion of points perpendicular to the short-term identity line — SD1 (, ) and negatively with LF/HF (, ). Regarding daily physical activity, SDNN at rest (, ) and exercise (, ) showed positive correlations with time in moderate-to-vigorous activities. When normalizing the SDNN and classifying individuals as normal or altered, those presenting altered SDNN showed poorest FEV1 () and lower exercise capacity ().Conclusion:HRV correlates with lung function, exercise capacity and levels of daily physical activity in children and adolescents with CF. The study highlights the influence of CF on autonomic function and suggests HRV measurement as an easy tool to be used in clinical settings as an alternative marker to monitor CF individuals. 相似文献

Objective
To review and classify the interval cancers found in the Principality of Asturias's Breast Cancer Screening Program (PDPCM). A secondary objective was to determine the histological characteristics, size, and stage of the interval cancers at the time of diagnosis.Material and methods
We included the interval cancers in the PDPCM in the period 2003-2007. Interval cancers were classified according to the breast cancer screening program protocol, with double reading without consensus, without blinding, with arbitration. Mammograms were interpreted by 10 radiologists in the PDPCM.Results
A total of 33.7% of the interval cancers could not be classified; of the interval cancers that could be classified, 40.67% were labeled true interval cancers, 31.4% were labeled false negatives on screening, 23.7% had minimal signs, and 4.23% were considered occult. A total of 70% of the interval cancers were diagnosed in the year of the period between screening examinations and 71.7% were diagnosed after subsequent screening. A total of 76.9% were invasive ductal carcinomas, 61.1% were stage II when detected, and 78.7% were larger than 10 mm when detected.Conclusions
The rate of interval cancers and the rate of false negatives in the PDPCM are higher than those recommended in the European guidelines. Interval cancers are diagnosed later than the tumors detected at screening. Studying interval cancers provides significant training for the radiologists in the PDPCM. 相似文献48.

Perineurioma is an extremely rare benign tumor of the peripheral nervous system composed exclusively of perineurial cells.
Imaging findings of this tumor are non-specific and the diagnosis is based on histologic studies. We report a case of perineurioma
of the kidney in a 7-year-old girl discovered incidentally during the evaluation of a urinary tract infection. This is the
first case of renal perineurioma reported in a child. We present the ultrasound and computed tomography findings of this histologically
confirmed neoplasm.

Background
Bariatric surgery (BS) is widely accepted for the treatment of patients with morbid obesity (MO). We aimed to determine presurgical predictors of and surgical technique-related differences in excess weight loss (EWL) 1?year after BS.Methods
This retrospective study included 407 subjects (F/M 3:1, median age?=?44?years) who underwent laparoscopic Roux-en-Y gastric bypass (RYGB, n?=?307) or sleeve gastrectomy (SG, n?=?100) at our University Hospital and were evaluated 1?year after surgery.Results
Baseline median (min–max) body mass index (BMI) was 47?kg/m2 (range?=?36–71). BMI was higher in the SG than in the RYGB group (53 vs. 46?kg/m2, p?0.0001). Simple correlation analysis showed negative associations between EWL and age, BMI, waist circumference (WC), fasting glucose, HbA1c, triglycerides (TG), blood pressure, and total cholesterol (all p?0.01). EWL (mean?±?SD) did not differ by gender (p?=?0.2), was lower in diabetic than in nondiabetic subjects (71?±?17% vs. 79?±?17%, p?0.0001), and higher in the RYGB vs. SG group (76?±?18% vs. 68?±?15%, p?0.0001). However, SG vs. RYGB differences in EWL disappeared (p?=?0.4) after taking into account baseline BMI. Multiple regression and logistic analysis showed that younger individuals with lower BMI but higher WC, and lower HbA1c and TG, had higher EWL and a higher rate of successful (EWL?≥?60%) weight loss.Conclusions
Our data indicate that some of the characteristics that would have subjects referred early for BS were associated with higher weight loss. Therefore, the timing of laparoscopic BS might be an important factor for MO individuals in which medical weight loss intervention has failed. 相似文献50.
Intra-articular knee injuries in children traditionally have been considered rarer than injuries in adults. Few studies establish the prevalence of knee injuries before skeletal maturity, but arthroscopic studies suggest an increased frequency of anterior cruciate ligament ruptures, meniscal tears, and osteochondral fractures. We report our experience with 15 anterior cruciate ligament injuries and 38 meniscus injuries treated between 1996 and 2001. The treatment of anterior cruciate ligament injuries is determined by Tanner's maturity criteria. In the three cases of Stage II injuries, surgery was delayed for up to 24 months in the 12 older patients, an immediate reconstruction was done using hamstring tendons in the three youngest patients, and patellar tendon treatment was done in the remaining cases. We had only one complication caused by the fracturing of the bone plug. The most frequent meniscus injuries were the traumatic tears (23 cases), 80% of which were peripheral and longitudinal. Whenever possible, the entire meniscus (suture in 4 cases) or the greater part of it (economic resection in 19 cases) should be conserved. Despite the satisfactory results, the average followup of the meniscal series (26.1 months) is too short a period to evaluate thoroughly the deterioration of the joint after a meniscectomy. 相似文献
