Sodium Hydroxide Chemical Matricectomy for the Treatment of Ingrown Toenails: Comparison of Three Different Application Periods

Objective Sodium hydroxide matricectomy is a successful method for the treatment of ingrown toenails. This study was designed to evaluate the optimal sodium hydroxide application period providing high success rates with minimal postoperative morbidity.
Materials and Methods Sixty-six patients with 225 ingrown nail edges were treated in three groups receiving 30-second, 1-minute, and 2-minute applications of sodium hydroxide. Each patient was reviewed postoperatively for pain, drainage, and tissue damage. The median long-term follow-up period was 14 months.
Results The success rate of the therapy was 70.9% in the first group, 92.7% in the second group, and 94.4% in the third group. In all groups, about half of the patients experienced minimal pain within 48 hours following the operation, but only in the third group, 20% of the patients had minimal pain, which continued about 1 week. Drainage and tissue damage were minimal or mild in all groups and disappeared within 3 weeks in the first and second groups but were prolonged to 6 weeks in the third group.
conclusion The success rate of 30-second application is significantly lower than 1-minute and 2-minute applications. Although the success rates of the latter two procedures are similar, the prolonged healing time is the disadvantage of the 2-minute application. We conclude that 1-minute application of 10% sodium hydroxide is simple, safe, and highly effective for the treatment of ingrown nails.     

Repair of large, anterior palatal fistulas using thin tongue flaps: long-term follow-up of 10 patients

Anteriorly based, thin tongue flaps were used in 10 patients to close large, anterior palatal fistulas. All 10 flaps (100%) survived, and complete closure was obtained in all patients, with the exception of a recurrent fistula that occurred in 1 patient during maxillary expansion (10%). Another patient (10%) demonstrated postoperative bleeding that required formal hemostasis under general anesthesia. No other complications were encountered. The results of this series indicate that the tongue flap is a safe technique for closure of large, anterior palatal fistulas. This thin, long flap is also reliable for orthodontic maxillary expansion.     

Effect of Recombinant Human Granulocyte/Macrophage Colony-Stimulating Factor on the Healing of Colonic Anastomosis in Rats

The purpose of this study was to investigate the efficacy of recombinant human granulocyte/macrophage colony-stimulating factor (rHuGM-CSF) on the wound healing of colonic anastomosis in rats. In total, 40 male Wistar rats were taken into this study. The control group (n = 20) received subcutaneous saline injection. The experiment group (n     

The Clinical Features of Comorbid Pediatric Bipolar Disorder in Children with Autism Spectrum Disorder

The aim of this study was to describe clinical features of PBD comorbidity in children with ASD. Forty children with ASD and PBD aged 6–18 years, and 40 age- and sex-matched ASD subjects with no affective episodes were included in the study. Autism Behavior CheckList, Abberant Behavior CheckList, and Young Mania Rating Scale-Parent Version were completed. This study shows that PBD comorbidity in children with ASD involves a highly episodic course, with manic episodes, subsyndromal symptoms and interepisodic periods commonly being described in the manic symptom profile of these children. These findings need to be repeated with large samples, together with controlled studies concerning therapeutic interventions directed toward PBD comorbidity in children with ASD.     

MRI quantification techniques in fatty liver: the diagnostic performance of hepatic T1, T2, and stiffness measurements in relation to the proton density fat fraction

PURPOSENonalcoholic fatty liver disease (NAFLD) can progress to liver cirrhosis and is predicted to become the most frequent indication for liver transplantation in the near future. Noninvasive assessment of NAFLD is important for diagnosis and patient management. This study aims to prospectively determine the liver stiffness and T1 and T2 values in patients with NAFLD and to compare the diagnostic performance of magnetic resonance elastography (MRE) and mapping techniques in relation to the proton density fat fraction (PDFF).METHODSEighty-three patients with NAFLD and 26 participants with normal livers were imaged with a 1.5 T scanner. PDFF measurements obtained from the multiecho Dixon technique were used to quantify the liver fat. MRE, native T1 mapping (modified Look-Locker inversion recovery [MOLLI] schemes 5(3)3, 3(3)3(3)5, and 3(2)3(2)5 and the B1-corrected variable flip angle [VFA] method), and T2 mapping values were correlated with PDFF. The diagnostic performance of MRE and the mapping techniques were analyzed and compared.RESULTST1 values measured with the MOLLI schemes and the B1-corrected VFA (p < 0.001), and the stiffness values from MRE (p = 0.047) were significantly higher in the NAFLD group. No significant difference was found between the groups in terms of T2 values (p = 0.127). In differentiation of the NAFLD and control groups, the B1-corrected VFA technique had slightly higher accuracy and area under the curve (AUC) than the MOLLI schemes. In the NAFLD group, there was a good correlation between the PDFF, MOLLI 3(3)3(3)5 and 3(2)3(2)5, and VFA T1 measurements (r=0.732; r=0.735; r=0.716, p < 0.001, respectively).CONCLUSIONLiver T1 mapping techniques have the potential to distinguish steatotic from nonsteatotic livers, and T1 values seem to have a strong correlation with the liver fat content.

Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease, with an estimated worldwide prevalence of around 25% (1). It may range from simple steatosis, which is considered a benign condition, to nonalcoholic steatohepatitis (NASH), which can progress to fibrosis, cirrhosis, liver failure, and hepatocellular carcinoma. NAFLD is also known to be associated with metabolic syndrome, which is a risk factor for cardiovascular disease and type II diabetes mellitus (2–4).The gold standard method for diagnosing NAFLD and distinguishing its different patterns is a liver biopsy which has considerable limitations, including sampling errors, its invasive nature and associated complication risks, small sample size, and inter- and intraobserver variability (5, 6). These drawbacks constrain its utility for clinical monitoring and make it unsuitable as a screening method. Therefore, there is an urgent clinical need for an accurate noninvasive approach in the assessment of NAFLD. Accordingly, both the European Association for the Study of the Liver and the American Association for the Study of Liver Disease propose magnetic resonance imaging (MRI) as a noninvasive diagnostic tool for NAFLD (7, 8). Proton density fat fraction (PDFF)-based MRI and magnetic resonance spectroscopy (MRS) techniques are considered the most accurate noninvasive methods for the quantification of liver fat (9–12). The PDFF is accepted as a standardized biomarker of hepatic steatosis. Studies suggest that this biomarker is equivalent to the hepatic “signal fat fraction” (FF) after correcting all the confounding factors (13). However, PDFF measurement is not suitable for the assessment of any inflammation or fibrosis in NAFLD (13). On the other hand, recent studies have shown that other quantitative MRI techniques such as magnetic resonance elastography (MRE) and T1–T2 mapping can be useful in detecting hepatic inflammatory and fibrotic changes (14, 15–21). Thus, the application of a multiparametric MRI protocol might be helpful in liver tissue characterization and thereby in the risk stratification and therapeutic management of patients with NAFLD.In this prospective study, we aimed to determine liver stiffness and T1 and T2 values in patients with NAFLD and nonsteatotic subjects and compare the diagnostic performance of MRE and mapping techniques in relation to the FF.
