Abstract
OBJECTIVE Infertility impacts a substantial number of couples worldwide, and about 50% of cases are linked to male factors. The analysis of seminal fluid composition can improve diagnostic accuracy and offer deeper insights into the pathophysiology of male factor infertility. This study seeks to identify novel markers for diagnosing and treating male infertility by comparing organic acid profiles in the seminal fluid of individuals with normospermia, oligospermia, and azoospermia. PATIENTS AND METHODS Semen samples were collected from men with normospermia, oligospermia, and azoospermia. The organic acid profile in the seminal fluid was analyzed using liquid chromatography-mass spectrometry/mass spectrometry (LC/MS-MS). Data analysis was performed using SPSS and MetaboAnalyst. RESULTS The study revealed significant differences in metabolite levels among normospermic, oligospermic, and azoospermic individuals. In groups with oligospermia, there were significant decreases in the levels of 2-OH-Isovaleric Acid, 3-Methyl-2-Oxovaleric Acid, Ethyl-Malonic Acid, Citric Acid, Oxoproline, Malic Acid, N-Acetyl-Aspartic Acid, Suberic Acid, Glutaconic Acid, and Succinic Acid. Similarly, individuals with azoospermia exhibited a notable reduction in the levels of Citric Acid, Malic Acid, and Suberic Acid. Furthermore, according to the Variable Importance in the Projection (VIP) score analysis, Ethyl-Malonic Acid, Glycolic Acid, and 3-Methyl-2-Oxovaleric Acid were identified as crucial factors for diagnosis and potential treatment strategies. CONCLUSIONS The data obtained from the study highlights the significant potential of metabolites in assessing infertility and gaining a more in-depth understanding of the underlying pathological mechanisms.

Abstract
OBJECTIVE The World Health Organization recognizes infertility as a public health issue. An estimated 48.5 million couples worldwide grapple with infertility. Infertility and spermatogenesis dysfunction arise from diverse genetic factors, including single-gene mutations and chromosomal abnormalities. Current research continues to explore other potential causes of infertility, leveraging both proteomic and metabolomic analyses. The primary aim of this study is to underscore the significance of investigating male infertility from a metabolomic perspective. PATIENTS AND METHODS This study aimed to identify new markers for diagnosing and treating male infertility by examining the carnitine profiles in seminal fluids of individuals diagnosed with the normospermic group, oligospermic group, and azospermic group, employing the LC/MS-MS method. RESULTS The first three L-carnitines C2 (Acetylcarnitine), C8:1 (Octenoylcarnitine), and C16:1 (Palmitoleylcarnitine), emerged as potential novel markers for diagnosis and treatment. CONCLUSIONS Based on these findings, we posit that the results obtained in this study will aid in diagnosing, treating, and monitoring systemic diseases, and provide a foundation for more comprehensive future molecular studies aimed at enhancing prevention and treatment strategies for infertility.

Abstract
BACKGROUND The renin-angiotensin-aldosterone system was shown to be activated in severe COVID-19 infection. We aimed to investigate the relationship between angiotensin converting enzyme (ACE) levels, ACE gene polymorphism, type 2 diabetes (T2DM), and hypertension (HT) and the prognosis of COVID-19 infection. METHODS This cross-sectional study analyzed the clinical features of adult patients with SARS-CoV-2 infection. ACE gene analysis and ACE level measurements were performed. The patients were grouped according to ACE gene polymorphism (DD, ID or II), disease severity (mild, moderate, or severe), and the use of dipeptidyl peptidase-4 enzyme inhibitor (DPP4i), ACE-inhibitor (ACEi) or angiotensin receptor blocker (ARB). Intensive care unit (ICU) admissions and mortality were also recorded. RESULTS A total of 266 patients were enrolled. Gene analysis detected DD polymorphism in the ACE 1 gene in 32.7% (n = 87), ID in 51.5% (n = 137), and II in 15.8% (n = 42) of the patients. ACE gene polymorphisms were not associated with disease severity, ICU admission, or mortality. ACE levels were higher in patients who died (p = 0.004) or were admitted to the ICU (p<0.001) and in those with severe disease compared to cases with mild (p = 0.023) or moderate (p<0.001) disease. HT, T2DM, and ACEi/ARB or DPP4i use were not associated with mortality or ICU admission. ACE levels were similar in patients with or without HT (p = 0.374) and with HT using or not using ACEi/ARB (p = 0.999). They were also similar in patients with and without T2DM (p = 0.062) and in those with and without DPP4i treatment (p = 0.427). ACE level was a weak predictor of mortality but an important predictor of ICU admission. It predicted ICU admission in total (cutoff value >37.092 ng/mL, AUC: 0.775, p<0.001). CONCLUSION Our findings suggest that higher ACE levels, but not ACE gene polymorphism, ACEi/ARB or DPP4i use, were associated with the prognosis of COVID-19 infection. The presence of HT and T2DM and ACEi/ARB or DPP4i use were not associated with mortality or ICU admission.

Abstract
PURPOSE Vitamin D deficiency has emerged as another potential risk factor for coronavirus disease (COVID-19) due to the immunomodulatory effects of 25 hydroxyvitamin D [25 (OH)D]. Vitamin D receptor (VDR) gene polymorphisms such as Fok I, Bsm I, Apa I, and Taq I are also associated with different courses of viral infections. This study aimed to evaluate the association between the VDR gene polymorphism at Fok I, Taq I, Bsm I, and Apa I genotypes and the prognosis of COVID-19 in respect to vitamin D deficiency. METHODS Two-hundred ninety-seven patients with COVID-19 were enrolled. Serum 25 (OH)D levels were measured. Four variant regions of the VDR gene, FokI, BsmI, ApaI, and TaqI were determined. RESULTS Eighty-three percent of subjects had vitamin D deficiency, and 40.7% of the whole group had severe deficiency. Median 25 (OH)D level was 11.97 ng/ml. Vitamin D levels were not related to inflammatory markers, disease severity, admission to intensive care unit (ICU), and mortality. While disease severity was related to Fok I Ff genotype, it was Taq TT genotype for ICU admission. Moreover, the ApaI aa genotype was common among the patients who were died. None of the deceased subjects had the Fok I FF genotype. CONCLUSION 25 (OH)D levels were not related to the severity and mortality of COVID-19. VDR gene polymorphisms are independently associated with the severity of COVID-19 and the survival of patients.

Abstract
STUDY OBJECTIVE To determine the analgesic efficacy of TENS treatment in patients with renal colic in the emergency department (ED). METHODS This double-blind, randomized controlled trial was conducted in a tertiary care ED. Patients with a definitive diagnosis of renal colic were assigned (1:1) as randomized to receive the real TENS with frequency 100 Hz, pulse width 200 microseconds, voltage 2 mA, or placebo with sham TENS. Pain intensity was measured using visual analog scales (VAS) at baseline, after 15 and 30th minutes. RESULTS A total of 100 patients were included in the final analysis: 50 patients treated with real TENS and 50 patients treated with sham TENS. VAS scores in both groups were similar at baseline. The mean reduction in VAS score at 15 min was 33.3 ± 17.6 (95% Confidence interval (CI): 28.3 to 38.3) for the real TENS group and 14.9 ± 11.6 (95% CI 11.6 to 18.2) for the sham TENS group (mean difference: 18.4 (95% CI: 12.5 to 24.4, P < 0.0001). The mean reduction in VAS score at 30 min was 63.7 ± 21.1 (95% CI: 57.7 to 69.7) for the real TENS group and 14.9 ± 16.2 (95% CI: 19.5 to 10.3) for the sham TENS group (mean difference: 48.8, 95% CI: 41.4 to 56.3, P < 0.0001). Four patients (8%) in the real TENS group and 24 patients (48%) in the sham TENS group required the rescue medication after 30th minutes. CONCLUSIONS TENS is effective for acute pain treatment in renal colic patients in the ED. TENS therapy could be a treatment option for renal colic.

Abstract
OBJECTIVE To evaluate the association between maternal fructosamine levels at the time of delivery and stillbirth. DESIGN Secondary analysis of a case-control study. SETTING Multicentre study of five geographic catchment areas in the USA. POPULATION All singleton stillbirths with known diabetes status and fructosamine measurement, and representative live birth controls. MAIN OUTCOME MEASURES Fructosamine levels in stillbirths and live births among groups were adjusted for potential confounding factors, including diabetes. Optimal thresholds of fructosamine to discriminate stillbirth and live birth. RESULTS A total of 529 women with a stillbirth and 1499 women with a live birth were included in the analysis. Mean fructosamine levels were significantly higher in women with a stillbirth than in women with a live birth after adjustment (177 ± 3.05 versus 165 ± 2.89 μmol/L, P < 0.001). The difference in fructosamine levels between stillbirths and live births was greater among women with diabetes (194 ± 8.54 versus 162 ± 3.21 μmol/L), compared with women without diabetes (171 ± 2.50 versus 162 ± 2.56 μmol/L). The area under the curve (AUC) for fructosamine level and stillbirth was 0.634 (0.605-0.663) overall, 0.713 (0.624-0.802) with diabetes and 0.625 (0.595-0.656) with no diabetes. CONCLUSIONS Maternal fructosamine levels at the time of delivery were higher in women with stillbirth compared with women with live birth. Differences were substantial in women with diabetes, suggesting a potential benefit of glycaemic control in women with diabetes during pregnancy. The small differences noted in women without diabetes are not likely to justify routine screening in all cases of stillbirth. TWEETABLE ABSTRACT Maternal serum fructosamine levels are higher in women with stillbirth than in women with live birth, especially in women with diabetes.

Abstract
Background Acute gastrointestinal (GI) bleeding is a common cause of hospitalization. There are conflicting results regarding the effectiveness of early endoscopy in patients with upper GI bleeding. Objective The study aimed to determine the benefit of early endoscopy and the epidemiological characteristics of patients presenting to the emergency department with non-variceal acute upper GI bleeding. Methods Patients over 18 years of age who presented to the emergency department with upper GI between 2015 and 2016 and underwent endoscopy were included in the study. The patients were divided into two groups: early endoscopy group (endoscopy within the 24 h) and late endoscopy group (endoscopy after 24 h). Results Of 104 patients, 57.7% were man, and the mean age was 66.27 ± 17.64 years. Of the patients who underwent endoscopy, 80 (76.9%) were in the early endoscopy group. There was no difference in blood transfusion needs (P = 0.388), re-bleeding (P = 0.137), the need for surgery, and mortality rates with regard to the timing of endoscopy. The results of the receiver-operating characteristics curve analysis revealed patients with a GBS ≥ 9 were taken as high-risk, and a prognosis analysis was performed accordingly. However, in patients undergoing early endoscopy, a difference was detected with respect to the length of hospital stay (P = 0.011) and treatment costs (P = 0.030). In the comparison with the admission time (working/non-working h) and variables, there were no significant differences in the length of hospital stay (P = 0.230), transfusion needs (P = 0.348), re-bleeding frequency (P = 0.905), and treatment costs (P = 0.094). Conclusion Endoscopy within 24 h in the setting of acute upper non-variceal GI bleeding is associated with an increase in the length of hospital stay and treatment costs, but is not associated with re-bleeding, transfusion needs, need for surgery, and mortality.

Abstract
OBJECTIVE The aim of the present study was to investigate the neuroprotective effect of ceftriaxone in a rat brain ischemia/reperfusion injury model. METHODS The oxidative stress parameter, malondialdehyde (MDA) levels with or without ceftriaxone treatment in brain ischemia/reperfusion injured rats as well as in controls were measured in serum and brain tissue. Motor examinations of the rats were also performed. One-way Analysis of Variance (ANOVA) test was used for analysis. Duncan's Multiple Range Test was performed in multiple comparisons. p < 0.05 were considered statistically significant. RESULTS: The data of this study showed that ceftriaxone treatment reduced the MDA levels in brain tissues in ischemia/reperfusion injured rats. Moreover, Bederson motor scores were higher in the ceftriaxone treated group as compared to the ischemia group (p = 0.092). CONCLUSION These results suggest that ceftriaxone could be beneficial for the prevention of brain ischemia/reperfusion injury caused by acute arterial occlusion through reducing the tissue MDA level (Tab. 2, Fig. 5, Ref. 24).

Abstract
AIM Cornus mas L is commonly used due to its anti-inflammatory, anti-carcinogenic and anti-oxidant properties. In the study, the effects of C. mas L extract on a solid tumor were examined in the Ehrlich solid tumor model developed in Balb/C type mice. METHODS Ehrlich acid tumor (EAT) cells (1x106 EAT cell) from the stock animal were injected subcutaneously (s.c.) through the nape of the mice. Treatment groups of solid tumor-induced animals received 100 mg/kg and 200 mg/kg of C. mas L extract intraperitoneally (i.p.) for 14 days. RESULTS Tumor volumes and animal weights were found to be statistically significant compared to the control group (p < 0.05). AgNOR staining was performed in tumor tissues. Statistically significant differences were observed between the groups in terms of TAA/NA ratio (p < 0.05). Immunohistochemical and biochemical parameters were also evaluated. An estimation of tumor proliferation of the lung, liver, brain, kidney, testis and tumor antioxidant parameters viz. lipid peroxidation, reduced glutathione (GSH), glutathione S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) was made. CONCLUSIONS Our study showed that the anti-tumor effect of C. mas L in assisted tumor development with EAT cells, was mediated by the enhancement of oxidative stress with multiple mechanisms (Tab. 6, Fig. 12, Ref. 38).

Abstract
2,4-dinitrotoluene (2,4-DNT) is a priority environmental xenobiotic pollutant which has toxic, mutagenic, and carcinogenic properties. Thus, its biodegradation by applying recent approaches such as taking advantage of plant-bacteria interactions is crucial. In this work, the genes from Burkholderia sp. R34, necessary for 2,4-DNT degradation, were integrated into wild-type Pseudomonas putida (P. putida) KT2440 genome, and this strain, named KT.DNT, was inoculated to soil in in vitro conditions. To estimate the disappearance of 2,4-DNT in contaminated soil, samples were taken from different time intervals, extracted and analyzed using high-performance liquid chromatography (HPLC). Biotransformation of 2,4-DNT increased gradually and the degradation in soil after 14-days of treatment with the bacterium was found to be the 97.1%, indicating that the engineered strain could be a remarkable candidate for in situ bioremediation of 2,4-DNT-contaminated sites. In addition, in vitro interaction of this bacterium with a model plant, Arabidopsis thaliana (A. thaliana), enhanced lateral root and root hair formation together with dry root weight. Moreover, the initial 2,4-DNT concentration was decreased to 68% within 2 h with the plant-associated KT.DNT in liquid culture. Hence, the usage of this bacterium with plants could also be a promising application for the 2,4-DNT biotransformation.

Abstract
OBJECTIVE We aimed to evaluate the diagnostic impact of 18F-FDG PET/CT in staging apocrine breast carcinoma (ABC) and primary breast neuroendocrine carcinoma (PBNEC) and to demonstrate possible alterations of the 18F-FDG uptake in these histopathologic subtypes. In addition, we aimed to compare 18F-FDG PET/CT findings between ABC, PBNEC and invasive ductal carcinoma. MATERIAL AND METHODS A total of 570 patients and 585 breast lesions were retrospectively included in this study. After patients were classified into molecular subtypes according to the histopathological analysis, 18F-FDG PET/CT imaging was performed. The SUVmax findings of primary tumors obtained from 18F-FDG PET/CT were compared between the groups. RESULTS Invasive ductal carcinoma was the most prevalent breast carcinoma (77.7%, n=446), with a low proportion of ABC (4.1%, n=24) and PBNEC (2.4%; n=14) diagnosed. The highest mean SUVmax was calculated in HER2 subtype of ABC and 18F-FDG uptake ratio in HER2 and TN subtypes were found statistically higher than Luminal B type of ABC (p=0.038 and p=0.019, respectively). Although 18F-FDG uptake in Luminal B subtype of PBNEC was higher than Luminal A subtype, difference was not statistically significant. Additionally, the axillary metastasis rate was significantly higher in the ABC group (p=0.015). CONCLUSIONS The histopathological ABC subtype group showed different 18F-FDG uptake than the invasive ductal carcinoma group. Even if 18F-FDG uptake was lower in the PBNEC group than in the other groups, PET/CT showed and adequate performance in detecting primary tumors and metastases. The 18F-FDG PET/CT scan results may contribute to the initial staging and management of ABC and PBNEC patients.

Abstract
Objectives Repeated admissions of patients with undiagnosed psychiatric problems in emergency departments (ED) is a major contributor to patient unsatisfaction and overcrowding in EDs. We evaluated the presence of psychiatric disorders in non-emergent admissions in the ED of a tertiary care hospital. Materials and Methods This cross-sectional study was carried out in Eskisehir Osmangazi University Hospital between December 2015 and March 2016. The study group consists of 4320 non-emergent patients (31% of all admissions to non-emergent ED). Psychiatric assessments of patients were done using the Primary Care Evaluation of Mental Disorders (PRIME-MD) scale prior to their discharge from the ED. The Mann-Whitney U, Kruskal-Wallis and Chi-square tests, as well as multivariate logistic regression, were performed for statistical analysis. Results The mean age was 30 ± 11.7 years years ranging from 18 to 78 years. Among non-emergent cases, 44% had at least one psychiatric disorder. The most frequent psychiatric disorder was mood disorder (major and minor depression). Females with a comorbid disease and lower education level had increased risk for mood disorders, anxiety disorders, and somatoform disorders. Single males with a comorbid disease had increased risk for alcohol dependence. Conclusions Undiagnosed patients with psychiatric disorders appear to be frequent users of medical emergency department services. These results might be helpful in developing more effective strategies to serve the mental health needs of the undiagnosed. People's awareness of psychiatric disorders should be increased.

Abstract
Many types of aflatoxin cause problems for both public and animal health. Aflatoxin B1 (AFB1) is the most toxic and commonly encountered fungal toxin that appears in poultry feed and in feeds stored under unsuitable conditions. AFB1 decreases feed quality, egg production and fertility of hatching eggs. Also, AFB1 alters the development of embryos by infecting eggs. We investigated using sequence analysis the changes caused by different concentrations of AFB1 on the promoter sequences of the growth hormone regulated gene-1 (GHRG-1) in chick embryo at 13, 17, 19 and 21 days incubation. DNA isolated from the liver of chick embryos treated with different concentrations of AFB1 was separated using agarose gel electrophoresis to detect apoptosis, and DNA interaction with AFB1 was investigated using plasmids to detect changes in electrophoretic mobility and their effects on DNA. Base changes of the promoter sequences of GHRG-1 in 5 ng/egg, 15 ng/egg and 40 ng/egg doses of AFB1 were increased on day 19 compared to base changes of the same AFB1 doses on day 13. We also found that AFB at different concentrations changed the mobility of DNA by binding to it, and that high doses of AFB1 destroyed DNA. The DNA interaction study using plasmid demonstrated that AFB1 at high doses was bound to plasmid DNA, slowed its mobility and inhibited restriction cuts.

Abstract
OBJECTIVE Human chitotriosidase (ChT) is an active chitinase expressed by activated phagocytes. Increased ChT activity has been reported in systemic Candida albicans infections and in Gram-negative and Gram-positive bacterial infections, indicating that an increase in ChT activity reflects phagocyte activation. The aim of this study was to determine the changes in serum ChT activity in patients who underwent high dose chemotherapy (HDC) and stem cell transplantation (SCT), who are at an increased risk for fungal and bacterial infections due to depression of the immune system during the neutropenic period. PATIENTS AND METHODS A total of 55 SCT patients were included in the study. Serum ChT activity was determined before the initiation of HDC and during the neutropenic period after hematopoietic stem cell reinfusion on post-transplant first, fifth and tenth days. RESULTS Chitotriosidase levels before transplantation were significantly lower than the results at first, fifth and tenth days post-hematopoietic stem cell reinfusion. CONCLUSIONS Although the number of neutrophils was low, ChT enzyme activity was high in newly produced granules of neutrophils. Chitotriosidase may be supplemented as a drug for preventing and treating infections in the near future.

Abstract
BACKGROUND Here, we present our experience of 12 lung cancer cases operated with carinal sleeve pneumonectomy (CSP) from 2001 to 2011. METHODS 12 cases who had undergone CSP in our department from 2001 to 2011 were retrospectively evaluated and presented by taking into account their demographical and clinical features, the surgical technique that was used, the complications that developed and the latest conditions of these patients. RESULTS Of the 12 cases, 11 were male and 1 was female with a mean age of 58.6 years (40-71 years). 11 cases had right and 1 had left CSP. The ethiology for resection was lung cancer in all cases. 10 cases had carinal invasion of the lung cancer, 1 had bronchopleural fistula developing after right pneumonectomy, 1 had distal tracheal rupture due to intubation tube placed during pneumonectomy; these all resulted in performing CSP. Five patients developed complications during the postoperative period. Three cases developed recurrences/metastases during the follow-up. Nine patients died, 3 patients were alive and were followed-up by our department. For all the cases, the median survival was 9 months, the estimated survival rate of 2-years was 33%, and 5-year survival rate was 22%. Survival for 2-4 years was 71%. CONCLUSIONS We think that with increasing surgical experience better results are obtained in these technically demanding procedures.

Abstract
The objective of this work was to investigate the bactericidal activity of enrofloxacin against gyrA mutant and qnr-containing Escherichia coli isolates from animals. The minimum inhibitory concentrations (MICs) of gyrA mutant and qnr-containing E coli isolates ranged from 1 µg/ml to 32 µg/ml for enrofloxacin. Time-kill experiments were performed using selected E coli isolates. For the time-kill experiments, the colony counts were determined by plating each diluted sample onto plate count agar and an integrated pharmacokinetic/pharmacodynamics area measure (log ratio area) was applied to the colony-forming units (cfu) data. In general, enrofloxacin exhibited bactericidal activity against all the gyrA mutant E coli isolates at all concentrations greater than four times the MIC. However, the bactericidal activity of enrofloxacin for all the qnr-containing E coli isolates was less dependent on concentration. The results of the present study indicated that the genetic mechanism of resistance might account for the different bactericidal activities of enrofloxacin observed for the gyrA mutant and the qnr-containing E coli isolates. Therefore, in addition to MIC assays, genetic mechanism-based pharmacodynamic models should be used to provide accurate predictions of the effects of drugs on resistant bacteria.

Abstract
The aim of this study were to detect the gyrA, parC and marR mutations and qnr genes (qnrA, qnrB and qnrS) in 120 strains of Escherichia coli isolated from animals. European Committee on Antimicrobial Susceptibility Testing and Clinical Laboratory Standards Institute disc diffusion and minimum inhibitory concentration (MIC) tests, respectively, were used to determine fluoroquinolone (FQ) resistance, and molecular methods were used to detect the mutations and the genes. E coli isolates with an MIC of ≥8 mg/l had mutation at Ser-80 in parC in addition to mutations at Ser-83, Asp-87 or both in gyrA. The nucleotide change was detected in marR (Ser-3 → Asn, Ala-53 → Glu, Gly-103 → Ser, Tyr-137 → His). Only four E coli isolates (3.3 per cent) contained qnrA and qnrS, and qnrB was not detected. Two E coli isolates from healthy calves also contained qnrA and qnrS. The MICs of enrofloxacin and danofloxacin for qnr-containing E coli isolates ranged from 32 mg/l to 256 mg/l. The results of this study indicated that the FQ-resistant E coli isolates presented an alteration in gyrA (Ser-83 → Leu, Asp-87 → Asn) and parC (Ser-80 → Ile) with high MICs (8-256 mg/l), and there was a low prevalence of qnr genes among E coli isolated from animals.

Abstract
The need to optimize the use of all the information that modern technological tools have made available to the physician ENT/audiologist has increasingly emerged within the Italian scientific community. Towards this purpose, it is necessary to create a registry of the patients using cochlear implants (CIs). This registry will include a homogeneous summary of the information deriving from multiple sources related to daily clinical practice, in order to assess auditory benefits, safety and reliability in patients with cochlear implants, and organization over the national territory. The primary objectives relative to the above-mentioned analysis are to assess the impact of the use of cochlear implants on patient health, to ensure traceability of the devices currently used, monitoring their safety and reliability over time, to guarantee access of the technique in clinical and organizational conditions that can allow the best possible benefits. The aspects concerning implementation of the registry were discussed extensively during the first meetings of the Working Group (WG). In particular, owing to the complexity and high costs related mainly to the development of the technological aspects and the need to involve technological partners external to the WG, and to respect current privacy laws, the WG members decided that the project should be limited to proposal of a paper registry to be implemented at a later stage, possibly within the framework of successive research projects. During meetings, the WG members discussed various aspects of implementation of the registry, and in particular the scientific features connected to objectives, inclusion criteria, and structure of the forms needed for data collection and organizational aspects. A registry is proposed herein.

Abstract
The aim of this systematic review of the literature was to summarize the results of scientific publications on the clinical effectiveness of the cochlear implant (CI) procedure in children. The members of the Working Group first examined existing national and international literature and the principal international guidelines on the procedure. They considered as universally-accepted the usefulness/effectiveness of unilateral cochlear implantation in severely-profoundly deaf children. Accordingly, they focused attention on systematic reviews addressing clinical effectiveness and cost/efficacy of the CI procedure, with particular regard to the most controversial issues for which international consensus is lacking. The following aspects were evaluated: post-CI outcomes linked to precocity of CI; bilateral (simultaneous/ sequential) CI vs. unilateral CI and vs. bimodal stimulation; benefits derived from CI in deaf children with associated disabilities. With regard to the outcomes after implantation linked to precocity of intervention, there are few studies comparing post-CI outcomes in children implanted within the first year of life with those of children implanted in the second year. The selected studies suggest that children implanted within the first year of life present hearing and communicative outcomes that are better than those of children implanted after 12 months of age. Concerning children implanted after the first year of life, all studies confirm an advantage with respect to implant precocity, and many document an advantage in children who received cochlear implants under 18 months of age compared to those implanted at a later stage. With regard to bilateral CI, the studies demonstrate that compared to unilateral CI, bilateral CI offers advantages in terms of hearing in noise, sound localization and during hearing in a silent environment. There is, however, a wide range of variability. The studies also document the advantages after sequential bilateral CI. In these cases, a short interval between interventions, precocity of the first CI and precocity of the second CI are considered positive prognostic factors. In deaf children with associated disabilities, the studies analyzed evidence that the CI procedure is also suitable for children with disabilities associated with deafness, and that even these children may benefit from the procedure, even if these may be slower and inferior to those in children with isolated deafness, especially in terms of high communicative and perceptive skills.

Abstract
Sarcoidosis is an inflammatory multisystem disorder of unknown cause. Approximately 5-7% of patients manifest symptoms of central nervous system involvement, or neurosarcoidosis. Cranial neuropathy usually entails facial nerve palsy and optic neuritis. Sudden hearing loss has been reported in fewer than 20 cases. Herewith, two new cases of sudden hearing loss due to probable neurosarcoidosis are reported, each having a quite different clinical course. In one case, unilateral sudden hearing loss and facial palsy were the presenting symptoms of systemic sarcoidosis, while in the second, unilateral sudden deafness occurred despite ongoing immunosuppressive treatment for systemic sarcoidosis.

Abstract
A 39-year-old woman presented with ischemia of the left hand. Angiography revealed thrombosis of forearm arteries. Surgical intervention was unsuccessful. CT angiography revealed an exostosis on the distal humerus close to the brachial artery which we believe was the cause of repetitive minor trauma to the brachial artery leading to embolic occlusion of the radial and ulnar arteries. Early diagnosis of the underlying cause is the key to successful treatment of hand ischemia. For patients without risk factors for arterial occlusive disease, imaging of bony structures must be performed in order not to miss the likely cause of an insidious repetitive vascular trauma.

Abstract
PURPOSE To report complications after the implantation of intrastromal corneal ring segments (Keraring; Mediphacos, Belo Horizonte, Brazil) in keratoconic eyes using a femtosecond laser (IntraLase; Advanced Medical Optics, Santa Ana, California, USA) for channel creation. METHODS Retrospective chart review of 531 patients (850 eyes) who underwent Keraring insertion using a femtosecond laser for channel creation. Intraoperative and postoperative complications were recorded. RESULTS Intraoperatively, there were 22 (2.7%) cases of incomplete channel formation. The rest of the intraoperative complications were galvo lag error (system malfunction) [five eyes (0.6%)], endothelial perforation [five eyes (0.6%)] and incorrect entry of the channel [two eyes (0.2%)]. Postoperatively, there were 11 (1.3%) cases of segment migration, two (0.2%) cases of corneal melting and one (0.1%) case of mild infection. The overall complication rate was 5.7% (49 cases out of 850 eyes). CONCLUSION In this study, intracorneal ring segment implantation using a femtosecond laser for channel creation was related to a number of complications. The most common complications were incomplete channel creation (intraoperatively) and segment migration (postoperatively).
