A rare inguinal mass: Round ligament leiomyoma

INTRODUCTIONLeiomyoma of the round ligament is a rare condition and usually appears like an inguinal hernia.PRESENTATION OF CASEWe report a case of a 40 year-old women found to have an inguinal mass which it was finally diagnosed as leiomyoma.The patient was admitted to our hospital with a history of painless groin mass. The mass was thought to be irreducible inguinal hernia. Surgical exploration demonstrated a round ligament leiomyoma.DISCUSSIONA smooth muscle tumor in the round ligament of the uterus in the inguinal region is a rare entity and can be mistaken for an irreducible inguinal hernia. It is a rare condition occurring predominantly in premenopausal middle-aged women. Abdominal, inguinal, and vulvar locations have been described. Surgical excision is the curative treatment.CONCLUSIONLeiomyoma of the round ligament should be entertained as a possible etiology of inguinal mass.     

Alexithymia and Emotional Intelligence in Patients with Panic Disorder, Generalized Anxiety Disorder and Major Depressive Disorder

Emotional Intelligence (EI) is a broad personality construct signifying the ability to perceive and to regulate affects within oneself. Alexithymia is another personality construct denoting difficulty in identifying and expressing emotions, with an externally oriented thinking style. Although previously considered to be independent, some studies have shown that these constructs overlap. The aim of this study was to evaluate and compare the levels of EI and alexithymia in patients with panic disorder, major depressive disorder (MDD), and generalized anxiety disorder (GAD). The subjects included 171 psychiatric patients and 56 non-clinical controls. Psychiatric diagnoses were based on DSM-IV criteria. The Emotional Intelligence Scale-34 (EIS-34) and the Toronto Alexithymia Scale (TAS-20) were used to assess EI and alexithymia. All three patient groups scored statistically significantly higher than the non-clinical controls on TAS-20 total score and the TAS-20 subfactors of difficulty identifying feelings and difficulty describing feelings. EIS-34 scores were lower in patient groups than in the non-clinical controls, but only the EIS-34 intrapersonal subscale was significant difference. Total TAS-20 and EIS-34 scores in the patient cohort were inversely and significantly correlated These results reaffirm an overlap between EI and alexithymia with the intrapersonal factor of EI to be more dependent on the difficulty identifying feelings dimension of alexithymia in subjects with MDD and GAD.     

The effect of acrylamide incorporation on the thermal and physical properties of denture resins

PURPOSE

Polymethyl methacrylate (PMMA) is the most commonly used denture base material despite typically low in strength. The purpose of this study was to improve the physical properties of the PMMA based denture base resins (QC-20, Dentsply Ltd., Addlestone, UK; Stellon, AD International Ltd, Dentsply, Switzerland; Acron MC; GC Lab Technologies Inc., Alsip, Japan) by copolymerization mechanism.

MATERIALS AND METHODS

Control group specimens were prepared according to the manufacturer recommendations. In the copolymer groups; resins were prepared with 5%, 10%, 15% and 20% acrylamide (AAm) (Merck, Hohenbrunn, Germany) content according to the moleculer weight ratio, respectively. Chemical structure was characterized by a Bruker Vertex-70 Fourier transform infrared spectroscopy (FTIR) (Bruker Optics Inc., Ettlingen, Germany). Hardness was determined using an universal hardness tester (Struers Duramin, Struers A/S, Ballerup, Denmark) equipped with a Vickers diamond penetrator. The glass transition temperature (T_g) of control and copolymers were evaluated by Perkin Elmer Diamond DSC (Perkin Elmer, Massachusetts,USA). Statistical analyses were carried out using the statistical package SPSS for Windows, version 15.0 (SPSS, Chicago, IL, USA). The results were tested regarding the normality of distribution with the Shapiro Wilk test. Data were analyzed using ANOVA with post-hoc Tukey test (P<.01).

RESULTS

The copolymer synthesis was confirmed by FTIR spectroscopy. Glass transition temperature of the copolymer groups were higher than the control groups of the resins. The 10%, 15% and 20% copolymer groups of Stellon presented significantly higher than the control group in terms of hardness. 15% and 20% copolymer groups of Acron MC showed significantly higher hardness values when compared to the control group of the resin. Acrylamide addition did not affect the hardness of the QC-20 resin significantly.

CONCLUSION

Within the limitation of this study, it can be concluded that copolymerization of PMMA with AAm increased the hardness value and glass transition temperature of PMMA denture base resins.     

Lamotrigine augmentation in patients with schizophrenia who show partial response to clozapine treatment

BackgroundSeveral placebo controlled studies investigating lamotrigine augmentation of clozapine in schizophrenia patients with partial response have shown varying results. The aim of this study was to further investigate the efficacy and safety of this augmentation strategy, and its effect on the glutamatergic system through utilizing mismatch negativity (MMN) component of auditory event related potentials.MethodsThe study was designed to evaluate the efficacy and safety of lamotrigine augmentation of clozapine in a 12-week, double-blind, placebo-controlled, prospective, randomized design. Thirty-four patients diagnosed according to DSM-IV schizophrenia criteria and with partial response to clozapine were included. Patients were randomized to 25 mg/day of lamotrigine or placebo, gradually increasing up to 200 mg/day on the 6th week. The change in psychopathology was assessed with Positive and Negative Syndrome (PANSS), Calgary Depression (CDS) and Clinical Global Impression-Severity (CGI-S) scales. A neuropsychological test battery was administered and MMN measurements were also obtained at baseline and endpoint. Safety evaluation included physical examination, UKU Side Effect Rating Scale (UKU) assessment and serum drug level measurements.ResultsNo significant differences were found between the two treatment groups in PANSS Positive and General Psychopathology, CDS, neurocognitive test and UKU scores, as well as MMN measurements. PANSS Total, Negative and CGI-S scores showed significant improvement compared to lamotrigine in the placebo group.ConclusionThis study did not show any benefit of augmentation of clozapine with lamotrigine in schizophrenia patients with partial response. The need for further investigation of other augmentation strategies of clozapine in partially responsive schizophrenia patients is evident.     

Does combining magnetic-activated cell sorting with density gradient or swim-up improve sperm selection?

Purpose

The present study aimed to evaluate whether combining the magnetic-activated cell sorting (MACS) with density-gradient (DG) or swim-up (SU) sperm separation techniques can improve sperm selection to obtain higher quality spermatozoa.

Methods

Two commonly used sperm selection techniques, SU and DG, were compared to MACS combined with either SU or DG. Spermatozoa obtained from normozoospermic (n?=?10) and oligozoospermic (n?=?10) cases were grouped as SU, DG, SU+MACS, and DG+MACS followed by the analysis of sperm morphology, motility, DNA integrity, and the levels of Izumo-1 and PLCZ proteins.

Results

Although spermatozoa obtained by SU or DG when combined with MACS have improved aspects when compared to SU or DG alone, results did not reach a statistically significant level. Moreover, separation with MACS caused a significant loss in the numbers of total and rapid progressive spermatozoa.

Conclusions

Considering the cost/benefit ratio, MACS application together with traditional techniques may only be preferred in certain cases having higher concentrations of spermatozoa, but it does not seem to be an ideal and practical sperm selection technique for routine use.

     

The effect of inlay butterfly cartilage tympanoplasty technique on compliance

Conclusion: IBCT technique should be preferred owing to its high graft survival rate and ABG gain. While no significant difference was found in middle ear pressures between ears that underwent IBCT and normal ears, compliance values were found to be decreased in patients undergoing IBCT. However, the lack of correlation between ABG gain and compliance values indicated that compliance increase had no effect on post-operative ABG results. Objective: The aim of the present study was to compare tympanometric and audiological parameters in patients undergoing inlay butterfly cartilage tympanoplasty (IBCT) with their normal ears and to determine their difference with normal ear tympanometric parameters. Methods: Overall, 25 patients that underwent an operation between August 2010–May 2014 were included in the present study. In 13 of these patients, the ear that did not undergo operation was normal. 0.5, 1, 2, 4?kHz pure sound average values, tympanometric measurements and compliance values of normal and operated ears were compared. Results: The graft survival rate in patients was found to be 92%. Mean pre-operative air–bone gap (ABG) was 16.4?±?5.4 in patients, while mean post-operative ABG was 10.9?±?5.8, with a statistically significant difference (p?=?0.001) While there was no significant difference between operated and normal ears of patients in terms of middle ear pressure (0.441), compliance values were significantly higher in normal ears than those in operated ears (0.032). When post-operative ABG gain was compared with compliance values, no significant correlation was found between ABG gain and compliance measurements (r?=??0.025 and p?=?0.936).
