Examining the functions of the vascular endothelial growth factor/hypoxia-inducible factor signaling pathway in psoriatic arthritis.

Objectives: The present study aimed to examine the roles of the vascular endothelial growth factor (VEGF), hypoxia-inducible factor (HIF), and heme oxygenase-1 (HO-1) in psoriatic arthritis (PsA). Patients and methods: In this cross-sectional study conducted between November 2020 and May 2021, 64 patients (43 female, 21 male; mean age: 43.2±10.4 years; range, 22 to 60 years) with active PsA were included in the patient group, and 64 healthy volunteers (43 female, 21 male; mean age: 42.8±10.5 years; range, 23 to 61 years) were included in the control group. The demographic features of all cases were recorded. The following indices were used to assess the activity of PsA: Bath Ankylosing Spondylitis Disease Activity Index, Disease Activity Score in 28 joints (DAS28), and Visual Analog Scale. Additionally, Disease Activity in Psoriatic Arthritis (DAPSA) and Psoriasis Area and Severity Index (PASI) were used to evaluate the patients. The biochemical parameters of the patients were calculated. The serum levels of VEGF, HIF, and HO-1 were determined using an enzyme-linked immunosorbent assay. Results: When the molecule levels and clinical features of the groups were evaluated, it was found that the VEGF and HIF-1 levels were higher in the patient group compared to the control group (p<0.05). No difference was observed in the comparison of the HO-1 levels of the patient group and the control group (p<0.05). A positive correlation was found between VEGF, HIF-1, and HO-1 (p<0.05). A positive relationship was found between VEGF and HIF-1 and erythrocyte sedimentation rate, C-reactive protein, DAPSA score, and PASI score (p<0.05). It was also determined that there was a positive relationship between the HIF molecule and DAS28 (p<0.05). Conclusion: According to the results obtained in the present study, VEGF and HIF play a role in the etiology of PsA, and the observation of intermolecular correlation suggests that these molecules move together in pathogenesis.

Determination of Parasitic Contamination in Vegetables Collected from Local Markets in Izmir Province, Türkiye

OBJECTIVE: Fresh vegetables are an important part of a healthy and nutrient-rich diet but the consumption of raw vegetables without proper washing is the main way for transmission of parasites. This study was aimed at determining the rate of parasitic contamination in prewashed fresh vegetables sold at randomly selected 10 retail markets which is the last step to reach the consumer in Izmir, Türkiye. METHODS: A total of 80 samples selected from eight types of vegetables including tomato, spinach, lettuce, rocket, mint, parsley, dill, and cucumber were examined for parasitic agents microscopically by sedimentation method after washing samples with normal saline. Statistical analysis was performed using SPSS software version 20.0. RESULTS: Protozoan cysts, helminth eggs, and larvae were detected in 21 (26.2%) of 80 samples from eight different vegetable species. Rhabditidiform larvae 18.7%, Blastocystis spp. 5%, Toxocara spp. 2.5%; Ascaris spp., Fasciola spp., Entamoeba histolytica/ Entamoeba dispar and hooked worms were found in 1.2%. Spinach and mint samples were contaminated with parasites significantly more than other fresh vegetable samples (p<0.008, odds ratio =80.0; p<0.017, odds ratio =46.6 respectively). Cruznema spp., a plant nematode, was found at the highest rate according to the results of culture, polymerase chain reaction and sequencing, respectively. CONCLUSION: In this study, the parasitic contamination was found in approximately one of the four vegetables sold in randomly selected markets in Izmir. These findings show that vegetables sold in local markets can cause parasitic infections if they are consumed without adequate washing and awareness should be raised on this issue. In addition, it was concluded that morphological examinations should be confirmed by molecular studies and sequencing as much as possible in order to avoid misdiagnosis of rhabditidiform larvae.

Demographic and clinical characteristics of newborn pneumothorax patients and their effects on respiratory function tests during childhood.

PURPOSE: Pneumothorax is defined as the presence of air between the parietal and visceral leaves of the pleura, resulting in lung collapse. The aim of this study was to evaluate the respiratory functions of these patients when they reach school age and to reveal whether they cause permanent respiratory pathology. METHODS: The files of 229 patients who were hospitalised in a neonatal intensive care clinic had received a diagnosis of pneumothorax and had undergone tube thoracostomy were included in a retrospective cohort review. The respiratory functions of participants in the control and patient groups were evaluated using spirometry in a prospective cross-sectional study design. RESULTS: The study found the rates of pneumothorax to be higher in males, term infants and after caesarean delivery, mortality was 31%. Among patients who underwent spirometry, those with a history of pneumothorax had lower forced expiratory volume at timed intervals of 0.5 to 1.0 (FEV1), forced vital capacity (FVC), FEV1/FVC, peak expiratory flow (PEF) and forced expiratory flow 25-75% (MEF25-75). FEV1/FVC ratio was significantly lower (p < 0.05). CONCLUSION: Patients treated for pneumothorax in the neonatal period should be evaluated for obstructive pulmonary diseases during childhood using respiratory function tests.

Distribution and Phylogenetic Analysis of Subtypes and Alleles of Blastocystis sp. in the Stool Samples Collected from Patients with Gastrointestinal Complaints in Izmir, Turkey.

PURPOSE: Blastocystis sp. is one of the most prevalent intestinal protozoa found in humans and many other animals. The present study aimed to examine the distribution and genetic diversity of Blastocystis sp. in stool samples from patients with gastrointestinal complaints in Izmir, Turkey. METHODS: All stool samples of 439 patients with gastrointestinal complaints were examined by native-Lugol and trichrome staining. To investigate the presence of Blastocystis sp. in stool samples, DNA was isolated, and PCR was performed with the barcode region in the SSU rRNA gene. PCR positive samples were sequenced to identify subtypes and alleles of Blastocystis sp. RESULTS: The prevalence of Blastocystis sp. was found to be 16.6% (73/439) in patients with gastrointestinal complaints in Izmir, Turkey. Three different Blastocystis sp. subtypes were identified. ST3 (28/55; 51.0%) was the most common subtype followed by ST2 (19/55; 34.5%) and ST1 (8/55; 14.5%). Itching and diarrhea were the most prominent clinical symptoms in Blastocystis sp. positive patients. When clinical symptoms and subtypes were compared, diarrhea was found in 62.5%, 47.4%, and 46.4% of patients with ST1, ST2, and ST3 subtypes, respectively. In addition, itching was found in 37.5%, 32.1%, and 21.1% of patients with ST1, ST3, and ST2, respectively. Six distinct alleles were identified by allele analysis of Blastocystis 18S rRNA gene: allele 4 for ST1, alleles 9, 11, and 12 for ST2, and alleles 34 and 36 for ST3. In this study, Blastocystis sp. was detected in 16 of 21 districts, including the central and rural districts of Izmir. Although ST1 was detected in central districts, it was not found in rural districts. CONCLUSION: This study provides comprehensive data on the prevalence and molecular epidemiology of the genetic diversity at the level of subtypes and alleles of Blastocystis sp. in different districts of Izmir province in Turkey. To the best of our knowledge, this is the first study which evaluates the distribution of subtypes and alleles of Blastocystis sp. according to PCR and SSU rRNA gene sequencing in patients with gastrointestinal complaints in different districts of Izmir province in Turkey.

The Risk Factors and Clinical Features of Acanthamoeba Keratitis: First Time Detection of Acanthamoeba T5 Genotype from Keratitis Patients in Turkey.

PURPOSE: The primary aim of this study is to investigate Acanthamoeba in clinical samples of keratitis cases (n = 60), in contact lens (CL) and lens care solutions of asymptomatic CL users (n = 41), and to identify the genotypes in positive samples. The secondary aim is to assess the risk factors and clinical features of Acanthamoeba keratitis (AK) patients. METHODS: All samples from patients and asymptomatic CL users were examined by microscopy and inoculated in non-nutrient agar plates. PCR was performed using the DNA isolated from corneal scrapings, CL and lens care solution samples. Positive DNA samples were sequenced to determine the genotype of Acanthamoeba. RESULTS: In none of the samples, Acanthamoeba was identified by microscopy, while Acanthamoeba was detected in a patient with keratitis by culture method. However, Acanthamoeba was detected in 11.66% (7/60) of the keratitis patients by PCR. The genotypes of these isolates detected by sequencing were T4 (4), and T5 (3). Acanthamoeba was detected in none of the samples of asymptomatic CL users by any of the three methods. CONCLUSION: To best of our knowledge, this is the first study to detect T5 genotype in AK patients from Turkey. In addition, the CL use was found to be an important risk factor for AK.

Genotyping and Molecular Identification of Acanthamoeba Genotype T4 and Naegleria fowleri from Cerebrospinal Fluid Samples of Patients in Turkey: Is it the Pathogens of Unknown Causes of Death?

PURPOSE: This study was aimed to investigate the presence of pathogenic free-living amoebae (FLA) in suspected cases of meningoencephalitis with unknown causes of death in Turkey. METHOD: A total of 92 patients, who were diagnosed as meningoencephalitis, were enrolled. All cerebrospinal fluid (CSF) samples were directly microscopically examined and cultured. Acanthamoeba, N. fowleri and B. mandrillaris were further investigated using molecular diagnostic tools including real-time PCR, sequencing, and phylogenetic analyses. RESULTS: The examined CSF samples were not found positive for the presence of FLA by microscopic examination and culture method. However, two CSF samples were detected positive by real-time PCR assay. Of the positive CSF samples, one was identified as Acanthamoeba genotype T4 and the second positive sample was identified as N. fowleri belonging to genotype II. Furthermore, the pathogens diagnoses was verified through Sanger sequencing. CONCLUSION: This study was significant to report the presence of Acanthamoeba genotype T4 and N. fowleri genotype II in CSF samples by real-time PCR assay. The present study shows the significance of primary amoebic meningoencephalitis (PAM) and granulomatous amoebic encephalitis (GAE) as one of the differential diagnoses to be considered by clinicians during the evaluation of suspected meningoencephalitis or cases of unknown cause in Turkey. Using real-time PCR, this has made the rapid detection, in a short time-frame, of Acanthamoeba and N. fowleri in CSF samples from patients. The problems with qPCR is that it is not available in every laboratory, reagents are expensive, and it requires skilled and expert personnel to set up these assays.

External Ophthalmomiasis Cases in Sirnak

Dermatological cases caused by myiasis make up approximately 20% of travel diseases. Ocular involvement occurred in approximately 5% of these myiasis cases. The conjunctival involvement of Oestrus ovis (O. ovis) larvae, which is the active agent in most ocular infestation cases in humans, causes external ophthalmomyiasis. External ophthalmomyiasis was diagnosed because of O. ovis first-stage larvae that were removed from the conjunctiva of three patients who applied to the Sirnak State Hospital Eye Clinic with complaints of foreign body sensation, burning, stinging, watering, and redness in the eyes and swelling of the eyelids in July and October. All symptoms of the patients disappeared within a few days after the removal of the larvae. Ophthalmomyiasis due to O. ovis must be kept in mind in the differential diagnosis of patients presenting with similar eye complaints in areas where sheep and goat husbandry is performed intensely.

Therapeutic effects of apocynin on ovarian ischemia-reperfusion induced lung injury.

Ovarian ischemia-reperfusion (I-R) injury may damage remote organs, including the lungs. We investigated whether apocynin, a NADPH oxidase inhibitor, might protect against ovarian I-R induced apoptosis in the lungs of rats. Bilateral ovarian I-R was induced for 3 h, then apocynin was applied at two concentrations. Lung tissue was evaluated using spectrophotometric and immunohistochemical methods. We found that I-R increased total oxidant status (TOS), oxidative stress index (OSI) and myeloperoxidase (MPO) levels, and immunostaining of nuclear factor kappa-B (NF-κB), light chain 3B (LC3B), interleukin 1-beta (IL-1ß), caspase-3 and tumor necrosis factor-alpha (TNF-α), but decreased superoxide dismutase (SOD) values. Apocynin application to I-R injured rats enhanced recovery of lung tissue oxidants and improved both histology and frequency of apoptosis.

Analysis of Spontaneous Movements in Infants With Torticollis.

PURPOSE: This study aimed to investigate whether the movements and postures of 3- to 5-month-old infants with torticollis differ from those of infants without torticollis and to determine the relationship between clinical characteristics and the Motor Optimality Score (MOS) in torticollis. METHODS: Participants were 40 infants with torticollis and 40 infants developing typically without torticollis. The infants were evaluated with detailed general movement assessment. RESULTS: There were significant differences in the MOS and subcategory scores for age-adequate movement repertoire and observed postural patterns between groups. Clinical characteristics were not related to the reduction in the MOS. CONCLUSIONS: Infants with torticollis have differences in movements and postures at 3 to 5 months of age compared with controls. Strategies supporting the movement repertoire of infants with torticollis can be added to rehabilitation programs for infants with the lower MOS to optimize their motor development.

The evaluation of potential global impact of the N501Y mutation in SARS-COV-2 positive patients.

Rapid and reliable detection of severe acute respiratory syndrome coronavirus 2 mutations are significant to control the contagion and spread rate of the virus. We aimed to evaluate the N501Y mutation rate in randomly chosen positive patients with the polymerase chain reaction (PCR). The evaluation and analysis of the data with a retrospective approach in cases with mutations, in terms of public health, will contribute to the literature on the global pandemic that affects our society. Public health authorities will take the necessary precautions and evaluate the current situation. The N501Y mutation was detected in patients with positive Covid-19 PCR test results. The positive samples were examined based on the 6-carboxy-fluorescein (FAM) channel in reverse transcription PCR (RT-PCR) quantitation cycle (Cq) values as low Cq (<25), medium Cq (25-32), and high Cq (32-38) groups. In the study, 2757 (19.7%) of 13 972 cases were detected as mutation suspects and 159 (5.8%) of them were found to have mutations. The ages of the cases with mutations ranged from 1 to 88 years (mean age of 40.99 ± 17.55). 49.7% (n = 79) of the cases with mutations were male, and 50.3% (n = 80) were female. When the RT-PCR-Cq results were examined, it was seen that it varied between 11.3 and 35.03, with an average of 20.75 ± 3.32.

An Overview of Ischemia-Reperfusion Injury: Review on Oxidative Stress and Inflammatory Response.

Ischemia-reperfusion is a common health problem leading to several health conditions. The pathophysiology of ischemia-reperfusion is quite complex. Oxidative stress and inflammatory response contribute to ischemia-reperfusion mechanisms. Various parameters like proinflammatory cytokines, reactive oxygen species, occur during ischemia-reperfusion . There are several ways to investigate these values through biochemical and histopathologic findings. Malondialdehyde, glutathione, myeloperoxidase, superoxide dismutase, interleukin 6, interleukin 1ß, tumor necrosis factor alpha, caspase-3, nuclear factor-kappa ß, and LC3B (microtubu le-associated protein light chain 3, LC3) can be evaluated among these indicators.

BDNF, GDNF, NGF and Klotho levels and neurocognitive functions in acute term of schizophrenia.

BACKGROUND: Klotho and its relationship with neurotrophic factors and cognition in schizophrenia has not yet been investigated. In this study, the hypothesis that the blood serum levels of BDNF, GDNF, NGF and Klotho in schizophrenia patients and healthy controls would be related to cognitive functions was investigated. METHODS: In this study, two groups were assessed: schizophrenia patients (case group) who were hospitalised in the Psychiatry Clinic of Sakarya University Training and Research Hospital and healthy volunteers (control group). The patients were evaluated on the 1st and 20th days of their hospitalisation with the Positive and Negative Syndrome Scale (PANSS), the Brief Psychiatric Rating Scale (BPRS), the General Assessment of Functioning Scale (GAF) and the Clinical Global Impression Scale (CGI). For cognitive assessment, both groups were evaluated with the Wechsler Memory Scale-Visual Production Subtest (Wechsler Memory Scale III-Visual Reproduction Subtest) and the Stroop test. RESULTS: BDNF, GDNF, NGF and Klotho levels were lower in schizophrenia patients than in healthy controls. In the schizophrenia patients, on the 20th day of treatment, there was a statistically significant increase in BDNF compared to the 1st day of treatment. BDNF, GDNF and Klotho showed positive correlations with some cognitive functions in the healthy controls. BDNF, GDNF, NGF and Klotho levels were intercorrelated and predictive of each other in both groups. CONCLUSION: This study suggests a relationship between cognitive functions, neurotrophic factors and Klotho. Most of the results are the first of their kind in the extant literature, while other results are either similar to or divergent from those generated in previous studies. Therefore, new, enhanced studies are needed to clarify the role of Klotho and neurotrophic factors in schizophrenia.

Urapidil alleviates ovarian torsion detorsion injury via regulating oxidative stress, apoptosis, autophagia, and inflammation.

OBJECTIVES: This study aimed to determine anti-inflammatory, antioxidant, and antiapoptotic properties of urapidil (Ura) against ovarian torsion detorsion (T/D) injury in rats. MATERIALS AND METHODS: 40 female Wistar albino rats were grouped as sham, T/D, T/D+dimethyl sulfoxide (DMSO), T/D+Urapidil (Ura) 0.5 mg/kg (low dose), and T/D+Urapidil (Ura) 5 mg/kg (high dose) groups. In treatment groups, Ura was administered intraperitoneally just before detorsion. Biochemical parameters (TAS, TOS, MDA, MPO, and SOD) and immunohistochemical (IL-1ß, TNF-α, NF-κB, LC3B, and Caspase-3) analyzes were performed. RESULTS: In the T/D group, OSI and MPO levels were elevated significantly while TAS values decreased compared with the sham group. A significant difference occurred in the low dose treatment group in TAS and OSI levels compared with the T/D group. In the high dose treatment group, significant elevation in TAS but reduction in OSI and MDA levels were observed compared with the T/D group. Immunohistochemical staining resulted in IL-1ß, TNF-α, NF-κB, LC3B, and caspase-3 immunopositivity in the T/D group, while Ura treatment decreased those parameters. Intensive congestion and hemorrhage were observed in the T/D group, but contrary to this, treatment groups had alleviated congestion and hemorrhage. CONCLUSION: These results suggest that Ura demonstrated protective effects against ovarian T/D injury via anti-oxidative, anti-inflammatory, and anti-apoptotic features.

Acute Toxoplasmosis During Pregnancy: A Hard Call

Toxoplasma gondii is an obligate intracellular parasite that infects all animals, including humans, and causes toxoplasmosis. If toxoplasmosis occurs during pregnancy, it may affect the foetus owing to transplacental transmission. Such transmission may lead to foetal complications, some of which can be very serious, e.g. hydrocephaly and chorioretinitis; however, not all cases of acute toxoplasmosis during pregnancy result in foetal complications. The decision whether to continue or terminate the pregnancy is a difficult problem for families as well as healthcare professionals, thus making it important. Here we present a case of acute toxoplasmosis at 6 weeks of pregnancy. The patient was directly advised to terminate the pregnancy. However, with detailed laboratory analyses, close follow-up and treatment to prevent transplacental transmission, she successfully completed the pregnancy and eventually delivered a healthy baby. By presenting this case, we aimed to review acute toxoplasmosis during pregnancy.

Autopsy findings of an isolated persistent left superior vena cava in an intrauterine dead fetus.

Persistent left superior vena cava (PLSVC) is one of the cardiac system abnormalities with a 0.3-0.5% incidence and caused by inadequate obliteration of the left anterior cardinal vein during embryonic development. Prognosis of PLSVC is generally assumed to be good if it is not accompanied by other cardiac system abnormalities. During the routine ultrasound control of a patient at 25th week of pregnancy at the Obstetrics and Gynecology Department of Mersin University, PLSVC anomaly was detected in an intrauterine fetus. Then, intrauterine death occurred and after removal of the deceased fetus, PLSVC diagnosis was confirmed by autopsy. According to the autopsy findings, right superior vena cava (SVC) and azygos vein were found in normal course. PLSVC opened into the right atrium via enlarged coronary sinus. There was no connection between the two SVCs. On the left side of posterior mediastinum, instead of hemiazygos or accessory hemiazygos veins, a vein symmetrical to azygos was opened into PLSVC, similar to the one on the right. No other cardiac anomaly associated with PLSVC or any other pathology in the other parts of body that could be responsible for death was discovered during autopsy. There was no evidence indicating that PLSVC played any role in intrauterine exitus of the present case. However, as mentioned in the literature, the ectopic beats in the atrium wall of patients with isolated PLSVC and enlarged coronary sinus may lead to pathologies in the conduction system of the heart. Considering the intrauterine death of an isolated PLSVC case associated with cardiac conduction pathologies, we recommend that the common assumption of 'isolated PLSVC is not associated with death' should be reviewed by studies on large series and even intrauterine cases should be closely monitored for cardiac arrhythmia.

Investigation of Dientamoeba fragilis Prevalence and Evaluation of Sociodemographic and Clinical Features in Patients with Gastrointestinal Symptoms.

BACKGROUND: Dientamoeba fragilis is a protozoan parasite of the human gastrointestinal tract and still controversial in association with gastrointestinal symptoms. PURPOSE: We present cross-sectional study of the prevalence of D. fragilis, and sociodemographic and clinical features in the patients with gastrointestinal symptoms. METHODS: A total of 490 fecal specimens were collected from outpatients with gastrointestinal symptoms in the Department of Parasitology, Faculty of Medicine, Ege University and Celal Bayar University, Turkey. Fecal specimens were examined with microscopy and inoculated in Robinson medium. D. fragilis-positive samples were examined for the presence of other intestinal parasites using enzyme immunoassay. Real-time PCR analysis was performed on all samples. RESULTS: Of the 490 stool specimens examined by real-time PCR, 59 patients were positive for D. fragilis infection with prevalence rate of 12.04%. Forty-four of positive patients (74.5%) were found to be infected with only D. fragilis, while 23.7% were co-infected with Blastocystis and 1.7% were co-infected with Rotavirus. No statistically significant difference was found in all the examined patients in terms of D. fragilis positivity for all sociodemographic parameters. Loose stool consistency was associated with the presence of D. fragilis, with 18.3% (P = 0.001). When the clinical symptoms of all the patients participating in this study were examined, diarrhea was statistically more significant in patients with the presence of D. fragilis (16.3%; P = 0.001). The rate of diarrhea in D. fragilis-positive patients (84.09%; P = 0.0005) was higher than that of D. fragilis-negative patients and it was statistically significant. CONCLUSION: This study is important for assessing the prevalence of D. fragilis and its association with other factors in symptomatic patients in a large sample group in Turkey, as well as investigating the relationship of identified symptoms with the D. fragilis pathogenicity. It is suggested that D. fragilis in this case is not a commensal parasite but a pathogenic parasite and that the most common clinical symptom is diarrhea.

Is color Doppler a reliable method for the diagnosis of malrotation?

PURPOSE: The gold standard for the diagnosis of malrotation is barium contrast study of the upper gastrointestinal system (UGCS), while color Doppler ultrasonography (CDUS) is another method used in the diagnosis. We investigated the value of CDUS for the diagnosis of malrotation in this study. METHODS: UGCS images, CDUS images, plain abdominal images, demographic data, and symptoms of 82 patients who were investigated for presumed malrotation during a 7-year period were evaluated, retrospectively. RESULTS: All patients underwent CDUS, and 18% of these patients were diagnosed with malrotation as the superior mesenteric vein was seen to be on the left of the superior mesenteric artery. We found that 16% of the 75 patients who underwent UGCS were diagnosed with malrotation. The sensitivity and specificity of CDUS in the diagnosis of malrotation was found to be 93.8 and 100%, respectively. The respective values for UGCS were 91.7 and 98.4%. CONCLUSION: Current data in the literature and our results underline that UGCS may yield false-positive and false-negative results. Although CDUS was found to be a reliable method for the diagnosis of malrotation in our study, the limitations of UGCS are also recognized for CDUS. Prospective studies are needed to determine the more valuable method.

Fecal carriage of extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella spp. in a Turkish community.

BACKGROUND/AIM: The aim of this study was to determine the prevalence of fecal carriage of extended-spectrum beta-lactamase (ESBL)-producing bacteria, enzyme types, and risk factors affecting colonization. MATERIALS AND METHODS: A total of 576 stool samples from outpatients were examined between October 2012 and May 2013. Screening was done with selective EMB plates. ESBL were detected by double-disk synergy and confirmed agar strip gradient methods. Enzyme types were determined by PCR. RESULTS: The prevalence of fecal carriage was found as 30% (173 of 576). Recent use of antibiotics, hospitalization and surgical operation, diabetes, crowded household populations, and old age were associated with higher carriage rates. Of the ESBL-producing bacteria, 87.5% were positive for blaCTX-M genes. Of the blaCTX-M gene-positive isolates, 95.2% were positive for blaCTX-M-1 genes; among these, 82.2% were positive for blaCTX-M-3 and 67.7% were positive for blaCTX-M-15 genes while 62.5% isolates were positive for both blaCTX-M-3 and blaCTX-M-15 genes Conclusions: A high rate (30%) of fecal carriage of ESBL bacteria was found in an adult population. The predominant beta-lactamase enzyme types were CTX-M-3 and CTX-M-15.

Outpatient single-port laparoscopic percutaneous Morgagni hernia repair assisted by an optical forceps.

Morgagni hernia is a relatively rare form of diaphragmatic hernia in the pediatric age group and it is conventionally treated with open surgical repair. Minimal access surgery is currently being adapted for many procedures in children. However, to date just a few techniques have been described relevant to minimal access surgical repair of Morgagni hernia in children. Herein, we report two cases of Morgagni hernia repaired by a new single-port laparoscopic technique assisted by an optical forceps. Two infants, a one-year-old boy and an eight-month-old girl, were operated with this technique in just 26 and 35 min and were discharged with oral analgesic prescription by postoperative hour 5 and 8, respectively. In the English-language literature, these cases are the first reports of laparoscopic Morgagni hernia repair that were performed as an outpatient procedure. Also, the technique introduced can be easily applied by a single surgeon without an assistant to operate the laparoscope.

[Transverse myelitis associated with toxocariasis and the importance of locally produced antibodies for diagnosis]. / Toksokariyaza bagli bir transvers miyelit olgusu ve tanida yerel antikor üretiminin önemi.

Toxocariasis caused by Toxocara canis or less frequently by T.catis is a common parasitic infection worldwide. Clinical spectrum in humans can vary from asymptomatic infection to serious organ disfunction depending on the load of parasite, migration target of the larva and the inflammatory response of the host. Transverse myelitis (TM) due to toxocariasis is an uncommon illness identified mainly as case reports in literature. In this report, a case of TM who was diagnosed as neurotoxocariasis by serological findings has been presented. A 44-year-old male patient complained with backache was diagnosed as TM in a medical center in which he has admitted two years ago, and treated with pregabalin and nonsteroidal drugs for six months. Because of the progression of the lesions he readmitted to another center and treated with high dose steroid therapy for three months. After six months of follow up, improvement has been achieved, however, since his symptoms reccurred in the following year he was admitted to our hospital. Magnetic resonance imaging (MRI) examination revealed a TM in a lower segment of spinal cord. He was suffering with weakness and numbness in the left lower extremity. There was no history of rural life or contact with cats or dogs in his anamnesis. Physical examination revealed normal cranial nerve functions, sensory and motor functions. There has been no pathological reflexes, and deep tendon reflexes were also normal. Laboratory findings yielded normal hemogram and biochemical tests, negative PPD and parasitological examination of stool were negative for cysts and ova. Viral hepatitis markers, anti-HIV, toxoplasma-IgM, CMV-IgM, rubella-IgM, EBV-VCA-IgM, VDRL, Brucella tube agglutination, echinococcus antibody, autoantibody tests and neuromyelitis optica test were negative. Examination of CSF showed 20 cells/mm3 (mononuclear cells), 45 mg/dl protein and normal levels of glucose and chlorine. In both serum and CSF samples of the patient Toxocara-IgG antibodies were detected by Western blot (WB) assay. Low molecular weight bands (30-40 kDa) were detected in both of the samples by repeated WB testing. CSF revealed more intense bands suggesting local antibody production. Therefore the patient was diagnosed as neurotoxocariasis, and treated with steroid and mebendazole for six weeks. Clinical improvement was detected in the case and thoracic MRI revealed significant improvement in myelitis signs two months after treatment. In conclusion, toxocariasis should be considered in the differential diagnosis of TM although the involvement of central nervous system is rare and serological testing should be performed properly in the serum and CSF samples for the diagnosis.
