Correlation between early computed tomography findings and neurological outcome in pediatric traumatic brain injury patients.

Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in children. Head computed tomography (CT) is frequently utilized for evaluating trauma-related characteristics, selecting treatment options, and monitoring complications in the early stages. This study assessed the relationship between cranial CT findings and early and late neurological outcomes in pediatric TBI patients admitted to the pediatric intensive care unit (PICU). The study included children aged 1 month to 18 years who were admitted to the PICU due to TBI between 2014 and 2020. Sociodemographic data, clinical characteristics, and cranial CT findings were analyzed. Patients were categorized based on their Glasgow Coma Scale (GCS) score. Of the 129 patients, 83 (64%) were male, and 46 (36%) were female, with a mean age of 6.8 years. Falls (n = 51, 39.5%) and in-vehicle traffic accidents (n = 35, 27.1%) were the most common trauma types observed. Normal brain imaging findings were found in 62.7% of the patients, while 37.3% exhibited intracranial pathology. Hemorrhage was the most frequent CT finding. Severe TBI (n = 26, p = 0.032) and mortality (n = 9, p = 0.017) were more prevalent in traffic accidents. The overall mortality rate in the study population was 10.1%. In children with TBI, cranial CT imaging serves as an essential initial method for patients with neurological manifestations. Particularly, a GCS score of ≤ 8, multiple hemorrhages, diffuse cerebral edema, and intraventricular bleeding are associated with sequelae and mortality.

Posttraumatic epilepsy in critically ill children with traumatic brain injury.

PURPOSE: The aim of this study was to determine the clinical, laboratory, and radiological factors related with posttraumatic epilepsy (PTE). METHODS: The study is a multicenter descriptive cross-sectional cohort study. Children who followed up for TBI in the pediatric intensive care unit between 2014 and 2021 were included. Demographic data and clinical and radiological parameters were recorded from electronic case forms. All patients who were in the 6-month posttraumatic period were evaluated by a neurologist for PTE. RESULTS: Four hundred seventy-seven patients were included. The median age at the time of trauma was 66 (IQR 27-122) months, and 298 (62.5%) were male. Two hundred eighty (58.7%) patients had multiple traumas. The mortality rate was 11.7%. The mean duration of hospitalization, pediatric intensive care unit hospitalization and mechanical ventilation, Rotterdam score, PRISM III score, and GCS at admission were higher in patients with epilepsy (p < 0.05). The rate of epilepsy was higher in patients with severe TBI, cerebral edema on tomography and clinical findings of increased intracranial pressure, blood transfusion in the intensive care unit, multiple intracranial hemorrhages, and intubated patients (p < 0.05). In logistic regression analysis, the presence of intracranial hemorrhage in more than one compartment of the brain (OR 6.13, 95%CI 3.05-12.33) and the presence of seizures (OR 9.75, 95%CI 4.80-19.83) were independently significant in terms of the development of epilepsy (p < 0.001). CONCLUSIONS: In this multicenter cross-sectional study, intracranial hemorrhages in more than one compartment and clinical seizures during intensive care unit admission were found to be independent risk factors for PTE development in pediatric intensive care unit patients with TBI.

Seizure treatment with olfactory training: a preliminary trial.

OBJECTIVE: Epilepsy is a chronic condition characterized by recurrent seizures. Despite miscellaneous antiseizure medications, resistance to treatment is still approximately 30%. This resistance brings forward the multidisciplinary approach and complementary treatments. In this study, we aimed to investigate the effect of olfactory training on epileptic seizures with special aromas having antiseizure effects in patients diagnosed with drug-resistant epilepsy. METHODS: A total of 24 patients (14 pediatric and 10 adults) with drug-resistant epilepsy were recruited for the study. Participants were asked to inhale the standardized bottle filled with lavender aroma (Lavandula Angustifolia) twice a day (morning and evening) for 30-45 s (2 cm in front of nose; 10-15 s to right and left nostril and 10-15 s to both nostrils) for 3 months. The type, frequency, duration of seizures, the quality of life (SF-36 and PedsQL 4.0), and olfactory functions (Sniffin' Sticks Test and Pediatric Smell Wheel) were re-assessed. RESULTS: Statistical analysis showed that olfactory training decreased the seizure frequency (p < 0.001) and the seizure duration (p = 0.02). A global 50% seizure reduction was seen among patients. Moreover, olfactory training increased the quality of life (p = 0.003) and improved the olfactory function in both the pediatric and adult groups (p = 0.017, p = 0.05, respectively). There was no adverse reaction and no increase in seizure frequency. SIGNIFICANCE: The observations of the present investigation suggest that olfactory training is a successful complementary therapy with no adverse reaction in patients with drug-resistant epilepsy. Large cohort studies and longer follow-up periods are needed for providing olfactory training as a therapy modality in patients with epilepsy.

Successful treatment with therapeutic plasmapheresis of a pediatric patient with Guillain-Barré syndrome associated with neurobrucellosis.

Brucellosis is a multisystemic disease that can present with multiple signs and symptoms. Rarely, brucellosis can manifest as neurobrucellosis, with central or peripheral nervous system involvement. Guillain-Barré syndrome (GBS) is a post-infectious autoimmune disease that progresses rapidly, causing ascending muscle weakness, and is accompanied by areflexia/hyporeflexia. Regarding GBS etiology, it is thought to be an autoimmune disease, triggered by a previous bacterial or viral infection. There are a few Brucella-associated GBS case reports in the literature and in our opinion, only one of them is a pediatric patient. Herein we reported a case of GBS associated with neurobrucellosis, who was successfully treated with therapeutic plasmapheresis (TP) due to poor response to IVIG treatment.

The Effect of Body Mass Index on Treatment Outcomes in Patients with Metastatic Non-Small Cell Lung Cancer Treated with Platinum-Based Therapy.

To investigate the effect of body mass index(BMI) on treatment outcomes and side-effect profile in metastatic non-small cell lung cancer(NSCLC) patients receiving platinum-based chemotherapy(ChT) in the first-line setting. This was a retrospective analysis of 233 NSCLC patients who were treated and followed up from 2008 through 2018. NSCLC patients who had metastatic disease at the time of diagnosis and were treated with platinum-based ChT in the first-line setting were included. The patients were divided into 2 groups based on the BMI as follows; BMI < 25 kg/m2 and BMI ≥ 25 kg/m2. This retrospective analysis enrolled 233 patients, 35 (15.0%) of whom were female. The BMI in 132 patients (56.2%) was < 25 kg/m2. The median age was 58 years (range, 21-90). Median progression-free survival(PFS) was 7 mo, in the patients with BMI ≥ 25 kg/m2 compared to 5.0 mo, in those with BMI < 25 kg/m2 (p = 0.032), with corresponding median overall survival(OS) durations of 12 vs. 9 mo, (p = 0.003). In multivariate analysis, ECOG PS 2, grade III histology, and brain or bone metastasis negatively affected OS, whereas BMI ≥ 25 kg/m2 positively affected OS. A high BMI prior to therapy in patients with NSCLC treated with platinum-based ChT in the first-line setting was associated with more favorable PFS and OS.

Levetiracetam monotherapy in children with epilepsy: Experience from a tertiary pediatric neurology center.

OBJECTIVES: Levetiracetam (LEV) is a second-generation antiepileptic drug with high efficacy and tolerability in children and adults with epilepsy. We aimed to retrospectively assess the long-term efficacy, tolerability, and safety of LEV monotherapy in children with epilepsy. METHODS: All patients who received LEV monotherapy at the Ankara University Children Hospital between January 2010 and June 2020 were evaluated. This retrospective pediatric cohort study determined the efficacy and safety of LEV monotherapy in 281 outpatients with epilepsy. RESULTS: There were 281 patients, 50.5% female, aged 5 months to 18 years with a mean age of 9 years. Of these, 48% of patients had idiopathic epilepsy, 40.6% had symptomatic epilepsy, and 11,4% had cryptogenic/genetic epilepsy. Primary generalized seizures occurred in 61.6% of patients, focal seizures in 19.6%, both generalized and focal seizures in 15,3%, focal to bilateral tonic-clonic seizures in 2.5%, and undefined type of seizure in 1.1%. A total of 22.8% patients had an accompanying extra neurological disease, mostly cardiological and hematological. The range of final daily dose was 10-71 mg/kg/day, with mean 29.5 mg/kg/day. Duration of therapy ranged from 7 days to 96 months, with median 12 months (IQR: 6-22). For the all cohort, a 6th month retention rate was 81%, a 12th month retention rate was 71.4%, and a 24th month retention rate was 61.8%. Eighty five percent of the patients had a seizure reduction of at least 50% and 55.9% of patients remained seizure-free for median 12 months treatment duration with LEV monotherapy. Improvement of electroencephalography (EEG) findings was found in 42% of patients on control EEGs. A total of 67 adverse events were documented in 45 (16%) patients. The most common adverse events were behavioral problems such as aggression (n:18) and irritability (n:17). The discontinuation rate due to adverse events was 2.5%, and due to inefficacy was 5.3%. CONCLUSION: The present study suggests that the high retention rates, high percentage of seizure reduction, the low discontinuation rate due to adverse events and inefficacy, and the relatively benign and transient profile of adverse events make LEV preferable as monotherapy in the pediatric population.

Are the kidneys involved in lipoid proteinosis? Study of 22 patients.

AIM: Lipoid proteinosis (LP) is a systemic, progressive, rare genodermatosis that manifests in early life with mucocutaneous lesions. Kidney involvement has not been described before, hence we aimed to investigate kidney findings in LP patients. MATERIALS AND METHODS: In this cross-sectional study, LP patients who were followed up and diagnosed with clinical, histopathological and radiological findings in the Dermatology outpatient clinic were invited to the Pediatric Nephrology Clinic. Biochemical, spot urine and 24-hour urine collection tests and ultrasound scans were scanned for the functional and anatomical status of the kidneys. Healthy controls who visited the Pediatric Nephrology Clinic during study periods for other reasons were invited to participate as the control group. RESULTS: Data of 44 participants (22 LP patients, mean age 14.5 years and 22 healthy controls, mean age 14.3 years) were available for the analysis. Ultrasound scans revealed simple renal cysts in 68% of LP patients. The cysts were bilateral in 4 patients, while no cyst was detected in healthy controls. Biochemical parameters, proteinuria, and albuminuria were all within the normal reference range in both LP patients and healthy controls, whereas LP patients had statistically significant lower serum albumin and higher C-reactive protein levels than healthy controls. CONCLUSION: Multiple simple renal cysts were detected in the majority of LP patients, and this finding could be part of the systemic involvement of the disease. Renal functions and biochemical parameters were within the normal reference range, but low serum albumin and high C-reactive protein levels in LP patients may be the signs of elevated systemic inflammation. Although more studies are needed to better define these findings, the presence of many simple renal cysts in LP patients was found to be the most important finding of this study.

Hypomelanosis of Ito presenting with unilateral dilation of Virchow-Robin spaces: a case report.

Hypomelanosis of Ito is a rare heterogeneous neurocutaneous disorder often associated with central nervous and musculoskeletal system involvement. Herein, we report the first case of hypomelanosis of Ito in the literature presenting with unilateral dilation of Virchow-Robin spaces (VRS). A girl aged 16 years old presented with a 1-year history of headache. Her physical and neurological examinations were normal, except for the presence of unilateral cutaneous macular hypopigmented whorls and streaks on lower side of the right trunk and lower limb, termed as Blaschko's lines. She had mild deficits in cognitive and adaptive functioning. Hearing, renal, dental, ophthalmologic, metabolic, and cardiac assessments were normal. Brain magnetic resonance imaging (MRI) showed markedly unilateral hemispheric enlarged VRS without contrast enhancement and diffusion restriction. To the best of our knowledge, our case is the first report describing the unilateral hemispheric enlarged VRS in a patient with hypomelanosis of Ito. Our report suggested that hypomelanosis of Ito may have unilateral dilation of VRS in brain MRI.

The prognostic and predictive significance of serum thiols and disulfide levels in advanced non-small cell lung cancer.

Serum Total Thiol (TT), Native Thiol (NT), and Disulfide (SS) levels were found significantly lower in benign proliferative pathologies and cancer disease compared to healthy subjects. We conducted this prospective study to investigate the possible predictive and prognostic significance of these markers in non-small cell lung cancer (NSCLC), which is one of the most associated cancers with oxidative stress. This was a non-randomized, prospective, and case-control study of 120 subjects, including 60 patients with metastatic or inoperable NSCLC at the time of diagnosis and 60 demographically-matched controls. Morning fasting venous blood serum samples from both NSCLC and control group were stored at -80 °C for equal periods and then TT, NT, and SS levels were measured spectrophotometrically. Serum TT, NT, and SS levels were compared between groups and their relationships with demographic features and survival of NSCLC patients were analyzed. In results, Serum TT, NT, and SS levels were significantly lower in NSCLC patients than those in control group, with a low SS level being an independent indicator of poor survival.

Efficacy and tolerability of adjuvant therapy in ≥70-year-old patients with T3N0M0 colorectal cancer: An observational study.

BACKGROUND: This study aimed to retrospectively investigate the efficacy and tolerability of adjuvant chemotherapy in ≥70-year-old patients with stage IIA (T3N0M0) colorectal cancer. METHODS: Lymphovascular invasion, perineural invasion, margin positivity, dissected lymph node count of <12, and presence of perforation/obstruction were accepted as risk factors. Those patients with at least one risk factor were regarded as having high risk. RESULTS: The study included 168 patients, among which 95 (56.5%) were male and 73 (43.5%) were female. The median age of patients was 73 years (range: 70-94). One hundred one (60.1%) patients were identified to have high risk. Eighty-one (87%) patients received 5-flourouracil+leucovorin and 12 (13%) patients received capecitabine regimens as adjuvant chemotherapy. The patients receiving capecitabine regimen had significantly higher rates of dose reduction at initiation and during the treatment. Among low-risk group, there was no statistically significant difference between patients with and without adjuvant chemotherapy in terms of disease-free survival or overall survival (p = 0.528 and p = 0.217, respectively). In high-risk group, patients receiving adjuvant chemotherapy significantly differed from those not receiving adjuvant chemotherapy in terms of median disease-free survival and overall survival (p = 0.009 and p < 0.001, respectively). While the grade, lymph node status, and adjuvant chemotherapy were identified as the most significant independent factors for disease-free survival, the most significant factors for overall survival were the age, Eastern Cooperative Oncology Group performance status, adjuvant chemotherapy, and recurrence. CONCLUSION: The findings of our study showed improved disease-free survival and overall survival in high-risk ≥70-year-old patients who received adjuvant chemotherapy due to T3N0M0 colorectal cancer. We believe that 5-flourouracil+leucovorin or capecitabine regimens should be recommended for these older high-risk patients who could receive adjuvant chemotherapy regardless of age.

The impact of tumor regression grade on long-term survival in locally advanced rectal cancer treated with preoperative chemoradiotherapy.

PURPOSE: The aim of this study is to investigate the prognostic effect of tumor regression grade (TRG) on long-term survival in locally advanced rectal cancer treated with preoperative chemoradiotherapy. METHODS: Medical records of 182 patients with locally advanced rectal cancer, who were treated with preoperative chemoradiotherapy followed by surgery between 2002 and 2016, were retrospectively reviewed. TRG was classified into five categories based on the pathological response as follows - TRG1: no viable cancer cell, TRG2: single cancer cell or small groups of cancer cells, TRG3: residual tumor outgrown by fibrosis, TRG4: residual tumor outgrowing fibrosis, TRG5: diffuse residual tumor without regression. TRG1, (TRG2+TRG3), and (TRG4+TRG5) were grouped as complete response, intermediate response, and no response, respectively. RESULTS: Of the 182 patients with locally advanced rectal cancer, 112 (61.5%) were male. The mean age was 54.4 (range, 25-87) years. The total number of patients in complete response, intermediate response, and no response group was 24 (13.2%), 105 (57.7%), and 53 (29.1%), respectively. The corresponding five-year relapse-free survival and overall survival rates were 79.8%-92.3%, 74.7%-79.4%, and 55.7%-55.8%, respectively (p < 0.05 for relapse-free survival, p < 0.05 for overall survival). According to ypTNM stage, there was no significant difference in relapse-free survival among TRG groups in ypStage I and II patients (p > 0.05). In ypStage III patients, relapse-free survival was 62 months in no response group vs. not reached in intermediate response group (p < 0.05). According to the ypTNM, there was no significant difference in overall survival among TRG groups in ypStage I, II, and III patients (p > 0.05). In the multivariate analysis, pathological complete response was found to be an independent variable for relapse-free survival and overall survival (hazard ratio (95% confidence interval), 0.34 (0.17-6.77), 0.39 (0.18-0.83), respectively). CONCLUSION: This study showed that patients with pathological complete response to preoperative chemoradiotherapy had longer relapse-free survival and overall survival rates than those with residual disease.

The short-term safety of adjuvant paclitaxel plus trastuzumab - A single centre experience.

PURPOSE: HER2-amplified breast cancer (BC) has a poor prognosis. The combination of trastuzumab with chemotherapy in the adjuvant setting decreases recurrence and improves overall survival in HER2-positive BC. However, the role of adjuvant treatment in patients with HER2-amplified small BC without lymph node involvement is still under debate. The purpose of this study was to investigate the safety of adjuvant paclitaxel and trastuzumab (APT) in this group of patients. METHODS: A total of 87 operated early BC patients without lymph node involvement (N0) were treated with APT for 12 weeks followed by trastuzumab alone for a total of 9 months. Clinicopathological features and adverse events were analyzed. RESULTS: The median patient age was 50 years (range 28- 82), and 51% of them were postmenopausal. The median tumor diameter was 2.4 cm (range 0.5-6), with 51% of the patients having tumor size between 2 and 3 cm. Eighty-one percent of patients had invasive ductal carcinoma (IDC), and 64% had grade 3 tumors. Adjuvant hormone therapy and adjuvant radiotherapy were administered to 65 and 54% of patients, respectively. At a median follow up of 13 months (range 6-38), one patient (1.1%, 95% CI 0-3.4) experienced an asymptomatic decrease in left ventricular ejection fraction (LVEF) and 3 patients (3.4%, 95% CI 0-6.9) experienced grade 3 neuropathy. CONCLUSIONS: APT appears to be a safe combination in early-stage, HER2-amplified and node-negative BC.

Clinicopathological features of patients with breast cancer aged 70 years or over.

PURPOSE: The risk of breast cancer (BC) increases in parallel with increasing age. Despite the increased disease burden in elderly patients, there is still a great uncertainty regarding "how to manage" BC in aging-population. The purpose of this study was to investigate the clinicopathological features and treatment approaches of patients with BC aged 70 years or over. METHODS: The medical records of 4413 patients with BC followed between 1994-2015 were retrospectively analyzed. Of the 4413 patients, 238 with stage I to III disease aged 70 years or over at BC diagnosis were enrolled into this study. Patients were divided into 2 groups according to the age as group 1 (70-79 years, N=192) and group 2 (80 or over, N=46). Clinicopathological features of patients including tumor histology, grade, estrogen (ER) and progesterone receptor (PgR) status, human epidermal growth factor receptor 2 (HER2) status, tumor size, lymph node involvement (LNI), lymphovascular invasion (LVI), perineural invasion (PNI), clinical stage, type of surgery, treatments and comorbid diseases were evaluated. RESULTS: The median age was 74 for group 1 (range 70-79) and 82 for group 2 (range 80-92). Excluding tumor size and grade, no statictically significant difference was found between the two groups according to histopathological characteristics. Patients in group 2 had more commonly larger T stage (T4), and less frequently presented with grade I tumor (p=0.014 and p=0.044, respectively). Modified radical mastectomy and adjuvant chemotherapy were more commonly performed in group 1 (p=0.001 and p=0.001, respectively). In contrast, neoadjuvant treatment was more frequently applied in group 2 (p=0.003). There was no difference in disease-free survival (DFS) between the groups (p=0.012), however, median overall survival (OS) was significantly higher in group 1 (p=0.03). CONCLUSION: Excluding the tumor grade and tumor size, both groups had similar histopathological features. However, patients aged between 70-79 years were likely to receive more agressive treatments for BC, indicating that treatment choice in patients over the age of 80 years was likely to be based on age-related factors rather than tumor characteristics.

Comparative study of receptor discordance between primary and corresponding metastatic lesions in breast cancer.

PURPOSE: It is well-known that tumor phenotype may change during the progression of breast cancer (BC). The purpose in this study was to compare the discordance in estrogen receptor (ER), progesterone receptor (PgR) and human epidermal growth factor receptor 2 (HER2) between primary and recurrent/metastatic lesions (RML) and also to evaluate the prognostic significance of change in tumor phenotype on survival in patients with metastatic BC. METHODS: The medical records of 6638 patients with BC from two breast centers treated between 1992 and 2015 were retrospectively analyzed. Of the 6638 patients, 549 cases in whom recurrence was histologically proven by biopsy or by surgical resection were enrolled into this study. RESULTS: Our presentation 13.5% of the patients had metastatic disease. Biopsy on recurrence was obtained from distant metastasis sites in 250 (63.6%) patients or from locoregional soft tissues/lymph-nodes in 143 (36.4%). Receptor discordance in ER, PgR and HER2 expressions between primary and RML were 27.2% (p=0.32), 38.6% (p<0.001) and 14.4% (p=0.007), respectively. Subsequent gain of ER and PgR showed significantly higher overall survival (OS) and post-recurrence survival (PRS) compared to the corresponding concordant-negative patients (119 vs 57 months, p=0.001 and 56 vs 31 months, p=0.03 for ER, 148 vs 58 months, p=0.003 and 64 vs 31 months, p=0.01 for PgR, respectively), hormone receptor (HR) loss was associated with worse OS. Similarly, HER2-loss cases experienced poorer PRS and OS outcomes, compared with those having stable HER2 expression (median 26 vs 60 months, p=0.009 for PRS and median 60 vs 111 months, p=0.06 for OS, respectively). CONCLUSION: This study confirmed the receptor discordance in ER/PgR and HER2 receptor expressions between primary and RML in patients with metastatic BC. As the loss of receptor expression is the most responsible factor for the discordance, treatments of recurrent/metastatic tumors should be individualized on the basis of molecular and genomic properties.

Low serum Insulin Like Growth Factor - 1 in patients with Stress Urinary Incontinence.

OBJECTIVE: SUI, involuntary loss of urine, occurs when intra abdominal pressure exceeds urethral pressure in women. Recent animal study has shown that there are therapeutic effects of Insulin-like growth factors (IGF-1) on stress urinary incontinence in rats with simulated childbirth trauma. IGF-1 is an important mediator of cell growth, differentiation and transformation in various tissues and stimulates fibroblast proliferation and enhances collagen synthesis. The purpose of the current study was to determine the association between IGF-1 levels and SUI. MATERIALS AND METHODS: All patients were evaluated for SUI and divided into two groups: 116 women with SUI and 76 women without SUI. Diagnosis of SUI was based on the International Consultation on Incontinence Questionnaire-Short Form (ICIQSF). Levels of IGF-1 were measured in serum by enzyme-linked immunosorbent assay. The relationship between IGF-1 levels and SUI in patients was evaluated statisticaly. RESULTS: The mean age of patients wiyh SUI was 49.9±8.6 and 48.7±7.8 in control group. Plasma IGF-1 levels were significantly lower in SUI than in control group (106.5±26.4 and 133.3±37.1ng/mL, respectively, P <0.001). Body mass indexes were higher in women with SUI than women without SUI. CONCLUSION: In this study lower serum IGF-1 levels were found to be associated with SUI. Serum IGF-1 level appears to be a specific predictor of SUI, and it may be used in early prediction of SUI in female population.

Current management of aromatase inhibitor-induced arthralgia.

Aromatase inhibitors (AIs) are standard of care in the adjuvant setting of postmenopausal women with hormone receptor positive breast cancer. Despite their beneficial effects on survival outcomes in breast cancer, AIs-induced arthralgia (AIA) is a common side effect which may lead to drug discontinuation and decreased AIs adherence among patients. So far, the exact pathophysiology of AIA is still an unclarified condition that explains why the optimal treatment in its management has not yet been established. Moreover, studies regarding the alternative treatment options for AIA are limited due to small sample size. Herein, we report a summary of current treatment options and their effectiveness in AIA with a practical algorithm in light of the relevant literature.

Effect of metabolic syndrome on sexual function in pre- and postmenopausal women.

Female sexual dysfunction is a prevalent and multidimensional disorder related to many biological, psychological, and social determinants. The authors assessed the effect of one of the many factors affect sexual function-metabolic syndrome-on female sexual function. They equally divided 400 women participants among 4 groups: (a) premenopausal with metabolic syndrome, (b) premenopausal without metabolic syndrome, (c) postmenopausal with metabolic syndrome, and (d) postmenopausal without metabolic syndrome. The authors used the Female Sexual Function Index to assess women's sexual function. Female sexual dysfunction was found more often in both pre- and postmenopausal women with metabolic syndrome (p =.001). Overall Female Sexual Function Index score and satisfaction, pain, and desire domain scores independently of the menopause status showed statistically significant differences across women with metabolic syndrome in comparison with participants with no metabolic syndrome (p <.05). The authors also evaluated the associations among 5 components of metabolic syndrome and Female Sexual Function Index scores. Higher fasting glucose levels were significantly associated with the Female Sexual Function Index score (p <.05). This study shows that sexual dysfunction is more prevalent in pre- and postmenopausal women with the metabolic syndrome.

Protective effect of hydrogen sulfide on renal injury in the experimental unilateral ureteral obstruction.

INTRODUCTION/OBJECTIVE: Ureteral obstruction is a common pathology and causes kidney fibrosis and dysfunction at late period. In this present study, we investigated the antifibrotic and antiinflammatory effects of hydrogen sulfide on kidney damage after unilateral ureteral obstruction (UUO) in rats. MATERIALS AND METHODS: 24 rats were divided into four groups. Group 1 was control, group 2 was sham, group 3 included rats with UUO and group 4 rats with UUO which were given sodium hydrogen sulfide (NaHS)-exogenous donor of hydrogen sulfide (intraperitoneally 56 µmoL/kg/day). After 14 days, rats were killed and their kidneys were taken and blood analysis was performed. Tubular necrosis, mononuclear cell infiltration and interstitial fibrosis were determined histopathologically in a part of the kidneys; nitric oxide (NO), malondialdehyde (MDA) and reduced glutathione (GSH) levels were determined in the other part of the kidneys. Urea-creatinine levels were investigated by blood analysis. Statistical analyses were made by the Chi-square test and one-way analysis of variance (ANOVA). RESULTS: There was no significantly difference for urea-creatinine levels among groups. Pathologically, there was serious tubular necrosis and fibrosis in group 3 and there was significantly decreasing of tubular necrosis and fibrosis in group 4 (p<0.005). Also, there was significantly increase of NO and MDA levels and decrease of GSH levels in group 3 compared to other groups (p<0.005). CONCLUSIONS: hydrogen sulfide prevents kidney damage with antioxidant and antiinflammatory effect.
