Monocyte/high-density lipoprotein ratio predicts the mortality in ischemic stroke patients

Objective

The inflammatory process is a very important stage in the development and prognosis of acute ischemic stroke (AIS). The monocyte to high-density lipoprotein (HDL) ratio (MHR) is accepted as a novel marker for demonstrating inflammation. However, the role of MHR as a predictor of mortality in patients with AIS remains unclear.

The association between serum vitamin B<Subscript>12</Subscript> deficiency and tension-type headache in Turkish children

This study aimed to determine the relationship between serum vitamin B₁₂ level and tension-type headache. The study groups consisted of 75 patients (40 females, 35 males) with headache and a control group of 49 healthy children (25 females, 24 males). Serum vitamin B₁₂ level <?200 pg/ml was defined as deficient, and <?160 pg/ml as severely deficient. The serum vitamin B₁₂ level was measured by the electrochemiluminescence (ECLIA) method. The serum vitamin B₁₂ levels in the headache and control groups were 273.01?±?76.77 and 316.22?±?74.53 pg/ml, with the difference determined as statistically significant (p?=?0.003). In the case group, 18/75 patients (24%) had a serum vitamin B12 level below the normal of 200 pg/ml, and in the control group 4/49 (8%) patients were also below the normal range (p?=?0.021). The serum vitamin B₁₂ level in the children with tension-type headache was significantly lower than that in the control group. From the results of the study, it was concluded that there may be an association between vitamin B₁₂ level and tension-type headache. However, further clinical studies are needed.     

Effects of infertility and infertility duration on female sexual functions

Objective

The objective was to evaluate the effects of infertility and its duration on female sexual functions.

Materials and methods

One-hundred and seventy-four (21.5 %) primary infertile cases, who attended the infertility outpatient clinic of our hospital, with a mean age of 31.2 ± 3.8 (range 20–45), have been determined as study group. In addition, 635 (78.5 %) cases with a mean age of 32 ± 3.2 (range 17–45) years, which attended the gynecology outpatient clinic with various complaints, were included as the control group. Infertile cases were grouped into three according to infertility duration: less than 2 years (Group I), 2–5 years (Group II), and 5 years and longer (Group III). Sexual dysfunction was evaluated via Turkish version of female sexual function index (FSFI) in the women who accepted to participate in this research.

Results

All the 809 cases incorporated in our study were found to be at risk for sexual dysfunction. Upon comparison between infertile and fertile groups, no meaningful statistical difference was determined within the scores of desire, arousal, lubrication, orgasm, sexual satisfaction, pain and total FSFI parameters (p > 0.05). The assessment on infertility durations showed that only sexual satisfaction scores were similar, whereas all other parameter scores and total FSFI scores were different significantly between all three groups. The scores got meaningfully lower as infertility duration of the couples extends (p < 0.05).

Conclusions

As the infertility duration extends, the scores of all parameters, except sexual satisfaction, decreases. But as many factors play a role in female sexual dysfunction, to blame prolonged infertility as a situation that negatively affects female sexual life, prospectively designed studies should be performed.     

Thiol-disulfide homoestasis in pregnancies with fetal growth restriction

Abstract

Aim: To investigate the role of dynamic thiol-disulfide homeostasis in preeclamptic and idiopathic fetal growth restricted (FGR) pregnancies.

Material and method: In this prospective case-control study, a total of 110 singleton pregnancies with FGR (study group) (51 preeclamptic and 59 idiopathic FGR’s cases) were compared with 68 healthy pregnant controls at the same gestational weeks (control group). For serum disulfide-thiol homeostasis, a newly used method described by Erel and Neselioglu was used.

Results: Serum native thiol and total thiol levels were lower in FGR pregnancies (285.63?±?55.92?µmol/L, 324.41?±?44.18?µmol/L, respectively) than control group (324.41?±?44.18?µmol/L, 362.98?±?51.43?µmol/L, p?<?.001, p?=?.004, respectively). In subgroup analysis, only preeclamptic FGR’s have lower native and total thiol levels (254.41?±?59.55, 324.41?±?44.18?µmol/L, respectively) compare to both idiopathic FGR’s and control’s. There was no difference in native and total thiol levels with idiopathic FGR’s with controls. Idiopathic FGR’s have higher levels of disulfide than preeclamptic FGR’s (21.72?±?17.72 versus 16.80?±?11.20?µmol/L). The serum albumin and total protein levels were positively and spot urine protein/creatinine ratio, 24-h urine protein levels were negatively correlated with native thiol and total thiol levels.

Conclusion: The balance of thiol-disulfide homeostasis was shifted and native and total thiol levels were decreased only in preeclamptic FGR pregnancies. The serum disulfide level was increased in idiopathic FGR pregnancies compare to preeclamptic FGR pregnancies which may be a sign of oxidative stress in idiopathic FGR pregnancies with normal thiol pool.     

A clinically isolated syndrome: A challenging entity

Abstract   Acute isolated neurological syndromes, such as optic neuropathy or transverse myelopathy, may cause diagnostic problems since they can be the first presentations of a number of diseases such as multiple sclerosis (MS) and collageneous tissue disorders. In the present study, particular systemic lupus erythematosus (SLE) and primary Sjogren syndrome (pSS) patients, who were followed up with the initial diagnosis of possible MS with no evidence of collagen tissue disorders for several years, are described. Five patients with the final diagnosis of SLE and five pSS patients are evaluated with their neurologic, systemic and radiologic findings. Over several years, all developed some systemic symptoms like arthritis, arthralgia, headache, dry mouth and eyes unexpected in MS. During the regular and close follow-up laboratory evaluations of vasculitic markers revealed positivity, leading to the final definite diagnosis of SLE or pSS. Patients with atypical neurological presentation of MS, a relapsing remitting clinical profile, or lack of response to the regular MS treatment should be evaluated for the presence of a connective tissue disease. Various laboratory tests, such as cerebrospinal fluid findings, autoantibodies profile, markers, cranial and spinal magnetic resonance imaging, can be helpful for the differential diagnosis. Lack of response to the regular multiple sclerosis treatment, even increasing rate of relapses can force the clinician for the differential diagnosis. In particular cases an accurate diagnosis can only be made after close follow-up.     

Serous borderline ovarian tumours: an extensive review on MR imaging features

Serous borderline ovarian tumours (SBOTs) are an intermediate group of neoplasms, which have features between benign and malignant ovarian tumours and for which, fertility-sparing surgery can be offered. MRI in imaging of SBOTs is, therefore, crucial in raising the possibility of the diagnosis, in order to present the patient with the most appropriate treatment options. There are characteristic MRI features that SBOTs demonstrate. In addition, recent advanced techniques, and further classification into subtypes within the borderline group have been developed. The aim of this article is to review the MRI features of SBOT and provide the reporter with an awareness of the imaging tips and tricks in the differential diagnosis of SBOT.     

Bariatric Surgery Promising in Migraine Control: a Controlled Trial on Weight Loss and Its Effect on Migraine Headache

Introduction

There is evidence that substantial weight loss through bariatric surgery (BS) may result in short-term improvement of migraine severity. However, it still remains to be seen whether smaller amounts of weight loss have a similar effect on migraine headache. This study has been designed to compare the effects of weight reduction through BS and non-surgical modifications.

Materials and Methods

Migraine characteristics were assessed at 1 month before (T0), 1 month (T1), and 6 months (T2) after BS (vertical sleeve gastrectomy (VSG) (n = 25) or behavioral therapy (BT) (n = 26) in obese women (aged 18–60 years) with migraine headache. Migraine was diagnosed using the International Classification of Headache Disorders (ICHDIIβ) criteria.

Results

There was significant reduction in the visual analog scale (VAS) from the baseline to T1 and T2 in both groups. The number of migraine-free days showed a significant increase within each group (p < 0.001). The BS group had a significant reduction in attack duration (p < 0.001) while there were no changes observed within the BT group. Following the adjustment of ANCOVA models for baseline values of migraine characteristics, age, changes in weight, BMI, body fat, and fat-free mass from T0 to T2, the BS group showed statistically significant lower VAS and duration of migraine attacks and a significantly higher number of migraine-free days than the BT group at T1 and T2 (p ≤ 0.028).

Conclusion

Our results indicated that far before significant weight reduction after BS (VSG), there was marked alleviation in the severity and duration of migraine and a significant increase in the number of migraine-free days in obese female migraineurs. However, the effects in the BT group were not comparable with the effects in the BS group.

     

Laser biostimulation of wound healing: bioimpedance measurements support histology

Laser biostimulation in medicine has become widespread supporting the idea of therapeutic effects of photobiomodulation in biological tissues. The aim of this study was to investigate the biostimulation effect of laser irradiation on healing of cutaneous skin wounds, in vivo, by means of bioimpedance measurements and histological examinations. Cutaneous skin wounds on rats were subjected to 635 nm diode laser irradiations at two energy densities of 1 and 3 J/cm² separately. Changes in the electrical properties of the wound sites were examined with multi-frequency electrical impedance measurements performed on the 3rd, 7th, 10th, and 14th days following the wounding. Tissue samples were both morphologically and histologically examined to determine the relationship between electrical properties and structure of tissues during healing. Laser irradiations of both energy densities stimulated the wound healing process. In particular, laser irradiation of lower energy density had more evidence especially for the first days of healing process. On the 7th day of healing, 3 J/cm² laser-irradiated tissues had significantly smaller wound areas compared to non-irradiated wounds (p?<?0.05). The electrical impedance results supported the idea of laser biostimulation on healing of cutaneous skin wounds. Thus, bioimpedance measurements may be considered as a non-invasive supplementary method for following the healing process of laser-irradiated tissues.     

Huge Varicose Inferior Mesenteric Vein: an Unanticipated 99m Tc-labeled Red Blood Cell Scintigraphy Finding

Ectopic varices (EcV) are enlarged portosystemic venous collaterals, which usually develop secondary to portal hypertension (PHT). Mesocaval collateral vessels are unusual pathways to decompress the portal system. Here we report the case of a huge varicose inferior mesenteric vein (IMV) that drained into perirectal collateral veins, demonstrated by ^99mTc-labeled red blood cell (RBC) scintigraphy performed for lower gastrointestinal (GI) bleeding in a 14-year-old girl. This case illustrates the crucial role of ^99mTc-labeled RBC scintigraphy for the diagnosis of rare ectopic lower GI varices.     

Clinical and impression cytology findings of amniotic membrane and oral mucosal membrane transplantation for the management of socket contracture

AIM: To investigate and compare the cytopathological and clinical effects of amniotic membrane transplantation (AMT) and oral mucosal membrane transplantation (OMMT) in socket contraction. METHODS:Twelve patients who could not be fitted with ocular prosthesis due to socket contracture were included in this study. Seven patients underwent AMT and 5 patients underwent OMMT. Thirteen patients who had healthy sockets were included as control group. Depth of inferior fornix, degree of inflammation, extent of the socket contracture and socket volume were measured in the preoperative period and at sixth and twelfth weeks postoperatively. Impression cytology of conjunctival fornices and tear transforming growth factor beta-1 (TGFβ1) levels were determined. RESULTS:In the AMT group,socket volume and lower fornix depth values were significantly higher (P=0.030 and P=0.004 respectively) and inflammation levels and impression cytology stages (P=0.037 and P=0.022 respectively) were significantly lower in postoperative period compared to preoperative period. In the OMMT group, no statistical differences were found in terms of clinical parameters, inflammation levels and impression cytology stages of preoperative versus postoperative values. Preoperative tear TGFβ1 levels were higher in AMT and OMMT groups compared to the control group (25.5 ng/mL, 26.3 ng/mL and 21.7 ng/mL respectively). Decreased tear TGFβ1 levels were observed in both the AMT and OMMT groups postoperatively (median decrease value=2.1 ng/mL and 2.7 ng/mL respectively). CONCLUSION: AMT is associated with postoperative improvement in inferior fornix depth, socket volume, inflammation and impression cytology levels and may be a more proper alternative method than OMMT in the management of socket contracture.
