Background: The Salter osteotomy and Pemberton acetabuloplasty are common procedures for a deficient acetabulum in patients with developmental dysplasia of the hip. However, the degree of increasing retroversion and anterior acetabular coverage of these two procedures remains unanswered. Questions/purposes: The purpose of this study is to show the change in anterior coverage and relevant parameters in measuring pain and function among patients who have undergone either a Salter osteotomy or Pemberton acetabuloplasty. Methods: Forty-two patients who underwent either a Salter or Pemberton procedure at one institution between January 1981 and December 2000 and were available for followup at least 10 years later (mean, 18 years; range, 12-28 years) were evaluated retrospectively. This represented 12% of the Salter and Pemberton procedures performed in patients between 12 and 36 months old at our institution during the study period. We measured vertical-center-anterior margin angle, anterior acetabular head index, and weightbearing zone acetabular index, and we made comparisons using the radiographic parameter ratio (the division of each radiographic measurement of the operative side by that of the nonoperated side). All patients completed SF-36 and Harris hip score questionnaires at followup. Results: In the Salter group, there were no differences in vertical-center- anterior margin angle, anterior acetabular head index, or weightbearing zone acetabular index. In the Pemberton group, there was no difference in vertical-center-anterior margin angle or anterior acetabular head index, but the weightbearing zone acetabular index decreased, suggesting increased anterior acetabular coverage (surgically treated side, 6 [95% CI, 4.84, 7.16]; nonoperated side, 12 [95% CI, 10.07, 13.39]; p < 0.001). Compared with that in the Salter group, the weightbearing zone acetabular index ratio was smaller in the Pemberton group, which means more acquired anterior coverage after a Pemberton acetabuloplasty (Salter procedure, 0.94 [95% CI, 0.70, 1.17], Pemberton procedure, 0.53 [95% CI, 0.40, 0.65]; p < 0.001). Three patients in the Pemberton group had an anterior impingement sign at followup, whereas none in the Salter group did. The SF-36 and Harris hip scores were good and showed no differences between the two groups. Conclusions: Our study suggests the weightbearing zone acetabular index on false profile radiographs of the hip, a parameter focusing on morphologic features of the anterior acetabulum, decreased after Pemberton acetabuloplasty compared with the nonoperated side and after the Salter acetabuloplasty. This suggests that by modifying the shape of the acetabulum with a hinge in the triradiate cartilage, a Pemberton acetabuloplasty may result in increasing acetabular anterior coverage and the risk of hip impingement. However, the functional results with at least 10 years followup were good and similar for both procedures. Level of Evidence: Level III, therapeutic study.

Background: It is essential to investigate the serotype distribution of pneumococcal diseases in each region and its associated clinical features. This study investigated the annual incidence of invasive pneumococcal disease (IPD) and the distribution of serotypes of isolates causing IPD at a medical center in northern Taiwan during the period 2000 to 2012. Methods: Serotypes of all available Streptococcus pneumoniae isolates causing IPD were determined using the latex agglutination test. Results: During the study period, the annual incidence (per 10,000 admissions) of IPD decreased significantly from 9.8 in 2000 to 2.1 in 2012 (P < 0.001). The annual incidence of all-cause bacteremia, primary pneumococcal bacteremia, bacteremic pneumonia, peritonitis, and meningitis also decreased significantly during the study period (P < 0.05). In contrast to the decrease in annual incidence of pneumococcal serotypes 14, 23F and 6B, the incidence and the proportion of serotype 19A significantly increased with time (P < 0.001). The coverage rate of 7-valent protein conjugated vaccine (PCV-7) and PCV-10 decreased significantly; however, the coverage rate of PCV-13 and pneumococcal polysaccharide vaccine (PPV-23) remained stable over time. Serotype 14 and 19A isolates were commonly isolated from blood and pleural effusion, respectively. Serotypes 14 and 23F were the two most common serotypes found in adult patients, and serotypes 14 and 19A were the two most common serotypes isolated from children. Conclusions: Although the incidence of IPD has decreased, serotype 19A is an emerging problem in Taiwan. The distribution of serotypes of pneumococci varied with clinical symptoms and age. As the changing distribution of pneumococcal serotype with time, the coverage rate of pneumococcal vaccines would be different. © 2014 Lai et al.; licensee BioMed Central Ltd.

Research in Autism Spectrum Disorders | Year: 2012

This study aimed to investigate the psychopathology, marital relationship, and family function in parents of children with autistic disorder (autism) as compared to parents of typically developing children. We also compared these measures between the mothers and the fathers. We assessed 151 families with at least one child with autistic disorder and 113 families of typically developing children in Taiwan. Both parents completed the self-administered questionnaires measuring psychopathology, marital dyadic adjustment, and family function. Both parents of children with autism suffered from more psychopathology and less dyadic consensus than parents of typically developing children; mothers of children with autism, perceived less marital satisfaction, affection expression, family adaptability and cohesion than mothers of typically developing children. We also found that mothers of children with autism displayed more psychopathology and marital maladjustment than did the fathers. These findings highlight that parents of children with autism encounter more psychological problems, marital difficulties and family dysfunction, particularly their mothers. © 2011 Elsevier Ltd.

Introduction. Although the association between epilepsy and sexual disorders has long been known, very few studies have attempted to explore the association between epilepsy and erectile dysfunction (ED). Aim. This population-based case-control study aimed to investigate the association between ED and a prior diagnosis with epilepsy. Methods. This study used data from the Longitudinal Health Insurance Database 2000 in Taiwan. The cases comprised 6,427 patients with a diagnosis of ED and 32,135 controls who were frequency matched with cases based on 10-year age groups and index year. Conditional logistic regression was used to calculate the odds ratios (ORs) for prior epilepsy. Main Outcome Measure. The prevalence and risk of epilepsy between cases and controls. Results. Of the sampled patients, 3,861 (14%) were diagnosed before the index date: 1,358 individuals (19.7%) were cases and 2,503 (12.1%) were controls. After adjusting for hypertension, diabetes, hyperlipidemia, renal disease, coronary heart disease, obesity, alcohol abuse/alcohol dependence syndrome, and socioeconomic status, conditional logistic regression analysis revealed that patients with ED were more likely to have been diagnosed with prior epilepsy than controls (OR=1.83, 95% CI=1.51-2.21). Compared with controls, the adjusted ORs for prior generalized epilepsy and partial epilepsy for cases were 2.13 (95% CI=1.52-3.00) and 1.64 (95% CI=1.31-2.06), respectively. The most pronounced associations were detected in ED cases aged between 30 and 39 who were 3.04 (95% CI=1.67-5.50) times more likely than controls to have been previously diagnosed with epilepsy. Conclusions. Our findings suggest a positive correlation between ED and a prior diagnosis with epilepsy. © 2012 International Society for Sexual Medicine.

Aims The expression of PUMA (p53-up-regulated modulator of apoptosis), an apoptosis-regulating gene, increases during endoplasmic reticulum stress. The mechanisms by which cyclic stretch influences the regulation of PUMA in vascular smooth muscle cells (VSMCs) during apoptosis remain unclear. We hypothesized that cyclic stretch enhances PUMA expression in VSMCs undergoing apoptosis. Methods and Results Human VSMCs grown on a Flexcell I flexible membrane base were stretched via vacuum to 20 of elongation at a frequency of 1 Hz. An in vivo model of volume overload with aorta-caval shunt and pressure overload with aortic banding in adult rats was used to study PUMA expression. Cyclic stretch markedly enhanced PUMA protein and gene expression after stretch. Addition of c-jun N-terminal kinase (JNK) inhibitor SP600125 and interferon-γ (IFN-γ) antibody 30 min before stretch inhibited PUMA expression. Gel shift assay demonstrated that stretch increased the DNA binding activity of interferon regulatory factor-1 (IRF-1). SP600125, JNK small interfering RNA, and IFN-γ antibody attenuated the DNA binding activity induced by stretch. PUMA-Mut plasmid, SP600125, and IRF-1 antibody attenuated the promoter activity. Stretch increased secretion of IFN-γ from VSMCs, and conditioned media from stretched VSMCs increased PUMA protein expression. The in vivo model of aorta-caval shunt and aortic banding also showed increased PUMA protein expression in the aorta. Conclusion Cyclic mechanical stretch increases PUMA expression in cultured human VSMCs. The PUMA expression induced by stretch is mediated by IFN-γ, JNK, and IRF-1 pathways. These findings suggest that PUMA is an important mediator in VSMC apoptosis induced by stretch. © 2011 The Author.

Leptin contributes to the pathogenesis of atherosclerosis. Ang II (angiotensin II), a proatherogenic cytokine, increases leptin synthesis in cultured adipocytes. Statin suppresses leptin expression in adipocytes and human coronary artery endothelial cells. However, the effect of Ang II and statin on leptin expression in VSMCs (vascular smooth muscle cells), the major cell types in atheroma, is poorly understood. Thus the aim of the present study was to investigate the molecular mechanism of atorvastatin for reducing leptin expression after Ang II stimulation in VSMCs. VSMCs from human coronary artery were cultured. Ang II stimulation increased leptin protein and mRNA and phospho-JNK (c-Jun N-terminal kinase) expression. Exogenous addition of Dp44mT (2,2'-dipyridyl-N,N-dimethylsemicarbazone) and mevalonate increased leptin protein expression similarly to Ang II. Atorvastatin, SP600125, JNK siRNA (small interfering RNA) and NAC (N-acetylcysteine) completely attenuated the leptin and phospho-JNK protein expression induced by Ang II. Ang II significantly increased ROS (reactive oxygen species) formation in human VSMCs. Addition of atorvastatin and NAC significantly attenuated the formation of ROS induced by Ang II. Addition of atorvastatin and SP600125 inhibited the phosphorylation of Rac1 induced by Ang II. The gel shift and promoter activity assay showed that Ang II increased AP-1 (activator protein-1)-binding activity and leptin promoter activity, while SP600125, NAC and atorvastatin inhibited the AP-1-binding activity and leptin promoter activity induced by Ang II. Ang II significantly increased the migration and proliferation of cultured VSMCs, while addition of atorvastatin, SP600125, NAC and leptin siRNA before Ang II stimulation significantly inhibited the migration and proliferation of VSMCs induced by Ang II. Ang II significantly increased secretion of leptin from human VSMCs, and addition of SP600125, atorvastatin and NAC before Ang II stimulation almost completely inhibited the leptin secretion induced by Ang II. In conclusion, Ang II induces leptin expression in human VSMCs, and atorvastatin could inhibit the leptin expression induced by Ang II. The inhibitory effect of atorvastatin on Ang II-induced leptin expression was mediated by Rac, ROS and JNK pathways. © The Authors Journal compilation © 2012 Biochemical Society.

Dysthyroidism has been highlighted as a common endocrine disorder associated with erectile dysfunction (ED); however, to date, no large-scale population-based study has investigated the association between hyperthyroidism and ED. This case-control study aimed to explore the association between ED and hyperthyroidism using a population-based data set. In total, 6310 adult patients who received new diagnoses of ED were recruited as cases together with 18 930 matched enrollees with no history of ED who served as controls. Conditional logistic regressions were conducted to explore the association between ED and having been previously diagnosed with hyperthyroidism. In total, 569 (2.3%) of the 25 240 sampled subjects had been diagnosed with hyperthyroidism before the index date; hyperthyroidism was found in 207 (3.3%) cases and 362 (1.90%) controls. After adjusting for potential confounding factors, the odds ratio (OR) of prior hyperthyroidism among cases was 1.64 (95% confidence interval1.37-1.96, P0.001) than that of controls. No association was detected between prior hyperthyroidism and ED for the 18-30, 30-39 and 70 age groups. Subjects aged between 60 and 69 years had the highest ORs for prior hyperthyroidism among cases when compared to controls (OR1.84; 95% confidence interval1.20-2.84; P0.001). Our study further confirms the existence of an association between ED and prior hyperthyroidism. © 2012 Macmillan Publishers Limited All rights reserved.

Introduction. While many studies have been conducted investigating the efficacy of varicocele treatment on fertility, the literature is comparatively sparse concerning the association between varicocele, varicocelectomy, and erectile dysfunction (ED). Aim. This study aimed to estimate the associations between varicocele, varicocelectomy, and ED using a population-based dataset. Methods. This study used data from the Longitudinal Health Insurance Database 2000 in Taiwan. A total of 32,856 cases and 98,568 randomly selected controls were included in this study. Conditional logistic regression analyses were used to examine associations between ED and having been previously diagnosed with varicocele or having underwent a varicocelectomy. Main Outcome Measure. The odds of prior varicocele or having underwent a varicocelectomy between cases and controls. Results. Of the sampled patients, the prevalence of prior varicocele was 3.3% and 1.2% for cases and controls, respectively (P<0.001). Conditional logistic regression analysis suggested that the odds ratio (OR) of being previously diagnosed with varicocele for cases was 3.09 (95% confidence interval [CI]=2.67-3.49) when compared with controls after adjusting for monthly income, geographic location, hypertension, diabetes, coronary heart disease, hyperlipidemia, hypogonadism, obesity, and alcohol abuse/alcohol dependence syndrome. Furthermore, cases were 1.92 (95% CI=1.52-2.43) times more likely to have undergone a varicocelectomy than controls. Furthermore, subjects aged between 18 and 29 had the highest ORs for prior varicocele among cases when compared with controls (OR=5.20; 95% CI=3.27-8.28). Conclusion. This investigation succeeded in identifying an association between both varicocele and ED. We also realized that varicocele patients who underwent a varicocelectomy had lower magnitudes of association with ED than those who did not. © 2012 International Society for Sexual Medicine.

Purpose: To date, the occurrence of erectile dysfunction (ED) associating with herpes zoster (HZ) is only based on limited case reports. This case-control study aimed at examining the association between HZ and ED using a population-based dataset in Taiwan. Methods: A total of 6429 adults newly diagnosed with ED were identified as cases, and 38,574 subjects without any medical history of ED were extracted as controls. Conditional logistic regression models were performed. Results: In total, 1.03% out of the sampled subjects had been diagnosed with HZ within one year prior to the index date; a higher proportion of prior HZ was found among cases than controls (2.04% vs. 0.86%, p < 0.001). After adjusting for demographic characteristics, hypertension, diabetes, coronary heart disease, hyperlipidemia, obesity, and alcohol abuse/alcohol dependence syndrome, conditional logistic regression suggested that cases were more likely to have previously been diagnosed with HZ than controls (OR = 2.24, 95% CI = 1.82-2.75). Furthermore, the odds of having been diagnosed with an HZ infection within one year prior to the index date were dramatically higher among patients with ED than controls among subjects aged 18-29 (OR = 6.07). Conclusions: We conclude that ED was associated with having been previously diagnosed with HZ, particularly among younger males. © 2012 The British Infection Association.

Introduction and hypothesis: Although one prior study reported an association between bladder pain syndrome/interstitial cystitis (BPS/IC) and urinary calculi (UC), no population-based study to date has been conducted to explore this relationship. Therefore, using a population-based data set in Taiwan, this study set out to investigate the association between BPS/IC and a prior diagnosis of UC. Methods: This study included 9,269 cases who had received their first-time diagnosis of BPS/IC between 2006 and 2007 and 46,345 randomly selected controls. We used conditional logistic regression analysis to compute the odds ratio (OR) and its corresponding 95 % confidence interval (CI) for having been previously diagnosed with UC between cases and controls. Results: There was a significant difference in the prevalence of prior UC between cases and controls (8.1 vs 4.3 %, p < 0.001). Conditional logistic regression analysis revealed that cases were more likely to have been previously diagnosed with UC than controls (OR = 1.70; 95 % CI = 1.56-1.84) after adjusting for chronic pelvic pain, irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, depression, panic disorder, migraine, sicca syndrome, allergy, endometriosis, and asthma. BPS/IC was found to be significantly associated with prior UC regardless of stone location; the adjusted ORs of kidney calculus, ureter calculus, bladder calculus, and unspecified calculus when compared to controls were 1.58 (95 % CI = 1.38-1.81), 1.73 (95 % CI = 1.45-2.05), 3.80 (95 % CI = 2.18-6.62), and 1.83 (95 % CI = 1.59-2.11), respectively. Conclusions: This work generates the hypothesis that UC may be associated with BPS/IC. © 2012 The International Urogynecological Association.
