Reduced left uncinate fasciculus fractional anisotropy in deficit schizophrenia but not in non-deficit schizophrenia

Aims: Schizophrenia is a psychiatric disorder manifesting with heterogeneous symptom clusters and clinical presentations. The deficit syndrome is the condition defined by the existence of primarily negative symptoms, and patients with the deficit syndrome differ from non‐deficit patients on measures of brain structure and function. In the current study, by using diffusion tensor imaging (DTI), we investigated the frontotemporal connectivity that is hypothesized to differ between deficit and non‐deficit schizophrenia. Methods: Twenty‐nine patients and 17 healthy controls were included in the study. The patients had deficit (n = 11) or non‐deficit (n = 18) schizophrenia and they were evaluated clinically with the Schedule for Deficit Syndrome (SDS) and Positive and Negative Syndrome Scale (PANSS). Diffusion‐based images were obtained with a 1.5T Siemens Magnetic Resonance Imaging machine and analyses were carried out with Functional Magnetic Resonance Imaging of the Brain Library Software – Diffusion tool box software. Results: The fractional anisotropy values in the left uncinate fasciculus of schizophrenia patients with the deficit syndrome were lower than those of non‐deficit patients and the controls. There were no differences between non‐deficit schizophrenia patients and controls. Conclusion: These findings provide evidence of left uncinate fasciculus damage resulting in disrupted communication between orbitofrontal prefrontal areas and temporal areas in deficit schizophrenia patients.     

Bilateral acute iris transillumination following a fumigation therapy: a village-based traditional method for the treatment of ophthalmomyiasis

Bilateral acute iris transillumination (BAIT) is a relatively new clinical entity characterized by bilateral acute loss of iris pigment epithelium, iris transillumination, pigment dispersion in the anterior chamber and atonic pupilla. We report herein a 50-year-old female who presented with bilateral ocular pain, severe photophobia and red eyes. One month ago, a fly hit her eye, and she instantly complained of a discomfort and sensation of a foreign body in both eyes. She used a fumigation therapy, a traditional method for the treatment of ophthalmomyiasis. During follow-up examinations, intraocular pressures increased over 40?mmHg bilaterally despite maximal medical therapy, which necessitated trabeculectomy surgery with mitomycin. This is a typical BAIT case with no antecedent fluoroquinolone use or viral disease, but a fumigation therapy. There might be a possible relationship between BAIT and traditional fumigation therapy or this association might be coincidental, both of which need further evaluation.     

Results of native and transplant kidney biopsies of children in a single center over a 15 years period

Renal biopsy is an important diagnostic procedure in pediatric nephrology. This study retrospectively investigates the indications, results and complications in a single tertiary children’s hospital in Turkey. We evaluated the native and transplant kidney biopsies in Gazi University Pediatric Nephrology Department between 2001 and 2015. A total of 196 biopsies (144 natives and 52 transplants) were included into the study. The mean age of the patients was respectively 10.8?±?3.5, 13.9?±?1.5?years. The main indication for a biopsy was non-nephrotic proteinuria with or without hematuria (n=?35), followed by steroid-resistance nephrotic syndrome (SRNS) (n?=?34) and Henoch-Schönlein purpura (HSP)–related proteinuria (n?=?20) for native kidneys. We found that focal segmental glomerulosclerosis (FSGS) (11.7%) was the most common histopathologic diagnosis for native kidneys, but acute cellular rejection (7.6%) was the most common histopathologic diagnosis for transplant kidneys. The complication rate in our study was founded 6.6% totally. Different complication rates were found in other studies; however, we think that this difference comes from the inspecting methodology of the complications. Hence, we wanted to share our own experience in the context of other studies in the literature.     

Oxidative stress status in congenital hypogonadism: an appraisal

Patients with hypogonadism are at increased risk of cardiac and metabolic diseases. However, the pathogenesis of increased cardiometabolic risk in patients with hypogonadism is not clear. Oxidative stress plays an important role in the pathogenesis of cardiometabolic diseases. This study aimed to investigate possible differences in oxidative stress conditions between patients with hypogonadism and healthy controls. In this study, 38 male patients with congenital hypogonadotropic hypogonadism (CHH) (mean age: 21.7?±?1.6?years) and 44 healthy male controls (mean age: 22.3?±?1.4 years) with almost equal body mass index were enrolled. The demographic parameters, follicle-stimulating hormone (FSH), luteinizing hormone (LH), total and free testosterone, homeostatic model assessment of insulin resistance (HOMA-IR) and oxidative stress parameters, such as superoxide dismutase, catalase (CAT), glutathione peroxidase (GPx) and malondialdehyde (MDA), were compared between both groups. Compared to the healthy controls, triglycerides (p?=?.02), insulin levels, HOMA-IR values, CAT activities and MDA levels (p?p?=?.04), total and free testosterone, FSH, LH levels and GPx activity were significantly lower (p?r?=??.33 p?=?.01), GPx activity (r?=?.36 p?=?.007) and MDA (r?=??.47 p?相似文献   

Postoperative fluid management

Postoperative care units are run by an anesthesiologist or a surgeon, or a team formed of both. Management of postoperative fluid therapy should be done considering both patients' status and intraoperative events. Types of the fluids, amount of the fluid given and timing of the administration are the main topics that determine the fluid management strategy. The main goal of fluid resuscitation is to provide adequate tissue perfusion without harming the patient. The endothelial glycocalyx dysfunction and fluid shift to extracellular compartment should be considered wisely. Fluid management must be done based on patient's body fluid status. Patients who are responsive to fluids can benefit from fluid resuscitation, whereas patients who are not fluid responsive are more likely to suffer complications of overhydration. Therefore, common use of central venous pressure measurement, which is proved to be inefficient to predict fluid responsiveness, should be avoided. Goal directed strategy is the most rational approach to assess the patient and maintain optimum fluid balance. However, accessible and applicable monitoring tools for determining patient's actual fluid need should be further studied and universalized. The debate around colloids and crystalloids should also be considered with goal directed therapies. Advantages and disadvantages of each solution must be evaluated with the patient's specific condition.     

Feasibility and Acceptability of Photographic Food Record,Food Diary and Weighed Food Record in People with Serious Mental Illness

People with serious mental illness (SMI) experience challenges that may make typical dietary assessment methods less feasible and accurate. This study aims to determine the feasibility, acceptability and preliminary validity of a 3-day photographic food record (PR), a 1-day food diary (FD) and a 1-day weighed food protocol (WR) in people with SMI. Participants completed measures at two timepoints, with a 4-week interval. Feasibility and acceptability for each method were measured through four outcomes: percent of completers, quality assessment, number of participants requiring technical devices and satisfaction questionnaire. Relative validity was measured by agreement in estimated energy intake between methods, using Bland–Altman analysis and WR as the benchmark, and prevalence of misreporting, using the Goldberg cut-off method, updated by Black. In total, 63 participants were recruited, with a dropout rate of 19.0% prior to timepoint 1 and additional 6.4% prior to timepoint 2. Quality deficits were identified for all methods. The FD was most acceptable to participants, followed by the PR. The difference in estimated energy intake between assessment methods was not statistically significant, though there was considerable individual variability. Underreporting was considerable across all methods but appeared highest in the PR. A FD and PR present as feasible and acceptable methods for assessing dietary intake in people with SMI. Further validity testing is required. In addition, clear guidance for completion and removal of potential barriers is required for participants.
