Palatal Implants for Persistent Snoring and Mild Obstructive Sleep Apnea After Laser-Assisted Uvulopalatoplasty

Laser-assisted uvulopalatoplasty (LAUP) was widely performed in 1990s as a surgical therapeutic procedure to improve snoring or mild obstructive sleep apnea (OSA). However, LAUP is not currently recommended as a treatment for OSA because the evidence for its efficacy is insufficient. Little is known about alternative minimally invasive surgery in patients who refuse continuous positive airway pressure or oral appliance after failed LAUP. We present a case of successful surgical treatment of persistent snoring and mild OSA with palatal implants after LAUP. This case suggests that palatal implants may be offered as an alternative surgical procedure for selective patients with persistent or recurrent snoring or mild OSA after LAUP

A Comparison of Different Pelvic Reconstruction Surgeries Using Mesh for Pelvic Organ Prolapse Patients

This study was carried out in order to compare the effects in different surgeries using mesh in pelvic organ prolapse patients whose leading points were C. Thirty-nine patients were categorized into 3 groups: group A pelvic reconstruction with hysterectomy; group B hysterectomy prior to pelvic reconstruction; and group C pelvic reconstruction with uterus preserved. At first visit, POP-Q stage was determined, and age, BMI, admission days, operation time, post-operative stage and complications were observed and results were analyzed and compared. All patients who were operated upon converted to stage one month following the operation, and no further change was observed except in one patient. Group admission days were not significantly different, but tended to be lower in group C. Group average operation times between 'group A and B' and 'group A and C' were statistically different. No significant difference was observed in post-operative complications between the groups, but 3 members of group A developed erosion, whereas no erosion occurred in groups B and C. Pelvic reconstruction using mesh is a highly efficient method of treating pelvic organ prolapse. Improvements in stage and post-operative complications were not significantly different in the groups. However, uteropexy showed a shorter operation time, fewer admission days, and less erosion due to mesh than conventional pelvic reconstruction with hysterectomy

Clinicopathologic Features and Treatment Outcomes in Differentiated Thyroid Carcinoma Patients with Concurrent Graves' Disease

The clinical behaviors and treatment outcomes of thyroid carcinomas in patients with Graves' disease is a matter of controversy. This study aimed to identify the clinicopathologic features, treatment outcome, and the indicators for predicting recurrence, and to suggest the optimal extent of surgery in these patients. We retrospectively analyzed data of 58 patients who underwent surgical treatment for differentiated thyroid cancer and concurrent Graves' disease. The follow-up period ranged from 23 to 260 months (mean±standard devuation, 116.8±54.0). In our series, the mean age was 40.8±12.7 yr (range, 15-70), with a male-to-female ratio of 1:6.25. The mean tumor size was 13±9 mm (range, 3-62). The surgical methods included 19 cases of total thyroidectomy, 38 cases of subtotal thyroidectomy, and 1 case of completion total thyroidectomy. Locoregional recurrence occurred in four patients (6.9%). The 10-yr overall survival and disease-free survival of patients were 95.8% and 91.1%, respectively. Age over 45 yr (p=0.031), tumor size over 10 mm (p=0.049), multiplicity (p=0.007), extracapsular invasion (p=0.021), and clinical cancer (p=0.035) were significantly more prevalent in patients with locoregional recurrence than in those without recurrence. We recommend that Graves' disease patients should undergo regular ultrasonography screening for early detection of thyroid carcinoma. We also suggest that the choice of extent of surgery should depend on the diagnostic timing (clinical or incidental) and factors for predicting recurrence

Status of Initiating Pattern of Hemodialysis: A Multi-center Study

This study was to evaluate the status of initiating pattern of hemodialysis (HD). Five hundred-three patients in 8 University Hospitals were included. Presentation mode (planned vs. unplanned), and access type (central venous catheters [CVC] vs. permanent access) at initiation of HD were evaluated, and the influence of predialysis care on determining the mode of HD and access type was also assessed. Most patients started unplanned HD (81.9%) and the most common initial access type was CVC (86.3%). The main reason for unplanned HD and high rate of CVC use was patient-related factors such as refusal of permanent access creation and failure to attend scheduled clinic appointments. Predialysis care was performed in 57.9% of patients and only 24.1% of these patients started planned HD and 18.9% used permanent accesses initially. Only a minority of patients initiated planned HD with permanent accesses in spite of predialysis care. To overcome this, efforts to improve the quality of predialysis care are needed

Carriage of the V279F Null Allele within the Gene Encoding Lp-PLA2 Is Protective from Coronary Artery Disease in South Korean Males

The Asia-specific PLA2G7 994G-T transversion leads to V279F substitution within the lipoprotein-associated phospholipase-A2 (Lp-PLA₂) and to absence of enzyme activity in plasma. This variant offers a unique natural experiment to assess the role of Lp-PLA₂ in the pathogenesis of coronary artery disease (CAD) in humans. Given conflicting results from mostly small studies, a large two-stage case-control study was warranted.PLA2G7 V279F genotypes were initially compared in 2890 male cases diagnosed with CAD before age 60 with 3128 male controls without CAD at age 50 and above and subsequently in a second independent male dataset of 877 CAD cases and 1230 controls. In the first dataset, the prevalence of the 279F null allele was 11.5% in cases and 12.8% in controls. After adjustment for age, body mass index, diabetes, smoking, glucose and lipid levels, the OR (95% CI) for CAD for this allele was 0.80 (0.66-0.97, p = 0.02). The results were very similar in the second dataset, despite lower power, with an allele frequency of 11.2% in cases and 12.5% in controls, leading to a combined OR of 0.80 (0.69-0.92), p = 0.002. The magnitude and direction of this genetic effect were fully consistent with large epidemiological studies on plasma Lp-PLA₂ activity and CAD risk.Natural deficiency in Lp-PLA₂ activity due to carriage of PLA2G7 279F allele protects from CAD in Korean men. These results provide evidence for a causal relationship between Lp-PLA₂ and CAD, and support pharmacological inhibition of this enzyme as an innovative way to prevent CAD
