To research how long-term positive airway pressure (PAP) therapy affects the severity of restless legs syndrome in patients with obstructive sleep apnea syndrome (OSASThe study included 320 individuals that were diagnosed with moderate and severe OSAS using polysomnography (PSG) and under PAP treatment. Among these patients, the demographic data of 72 patients who met the diagnostic criteria of restless legs syndrome (RLS) were analyzed. The patients were evaluated with the International RLS Study Group rating scale (IRLS) before and at the 12th month after PAP in the treatment of OSAS. The mean body mass index of the 72 patients with OSAS and RLS was 31.2 (±5.8), and their mean apnea-hypopnea index was 44.9±27.7. The prevalence of RLS in moderate and severe OSAS was 24%. There was a negative correlation between the IRLS score and mean oxygen saturation all night (r: -0.075), minimum oxygen saturation all night (r: -0.125), time spent below <90% saturation (r: -0.172), and sleep efficiency (r: 0.087) on PSG performed before PAP treatment, as well as a negative correlation between the IRLS score and weekly PAP use hours at the 12th month after PAP treatment (r: -0.316; p<0.001). The data obtained from this study suggest that the coexistence of OSAS and RLS is common and should not be overlooked in the diagnosis of comorbid diseases. Long-term PAP treatment is effective in reducing RLS symptoms. Further studies are needed on this subject.
为了研究长期气道正压(PAP)治疗如何影响阻塞性睡眠呼吸暂停综合征(OSAS)患者不动腿综合征的严重程度,该研究包括320名使用多导睡眠图(PSG)和PAP治疗被诊断为中度和重度OSAS的患者。分析其中符合不宁腿综合征(RLS)诊断标准的72例患者的人口学资料。采用国际RLS研究组评定量表(IRLS)对患者在PAP治疗OSAS前和治疗后12个月进行评估。72例OSAS和RLS患者的平均体重指数为31.2(±5.8),平均呼吸暂停低通气指数为44.9±27.7。中重度OSAS患者的RLS患病率为24%。在PAP治疗前进行的PSG中,IRLS评分与夜间平均血氧饱和度(r: -0.075)、夜间最低血氧饱和度(r: -0.125)、低于90%血氧饱和度的时间(r: -0.172)和睡眠效率(r: 0.087)呈负相关,并且在PAP治疗后第12个月,IRLS评分与每周PAP使用小时数呈负相关(r: -0.316;p < 0.001)。本研究数据提示OSAS和RLS共存是常见的,在合并症的诊断中不可忽视。长期PAP治疗可有效减轻RLS症状。这个问题需要进一步的研究。

Hereditary angioedema (HAE) is a rare autosomal dominant disease that is derived from the deficiency or dysfunction of C1 esterase inhibitor (C1-INH). In studies about the diseases that can accompany hereditary angioedema, allergic diseases occur more frequently compared to the healthy population but no studies on this issue have been carried out. This study was conducted in order to determine the frequency of the comorbidity of atopic sensitivity and allergic diseases in patients with hereditary angioedema. 32 patients who were diagnosed with hereditary angioedema in the Paediatric Allergy Polyclinic of Mersin City Hospital between 2019 and 2021 were included in the study. In these patients, the information about the existence of atopic diseases was obtained from their files and recorded. While asthma was observed in 6 (18.8%), allergic rhinitis in 18 (46.9%), and urticaria in 2 (6.2%) patients, dermatitis was not observed in any of the patients. While Fx5 test was positive in 5 (15.6%) patients, inhalant allergen mix sps IgE was positive in 7 (25.9%) patients. The IgE value was above 100 in 12 (52.2%) patients, and the eosinophil level was above 4% in 16 (50%) patients. In conclusion, we speculate in this study that the association of atopic disease and atopic sensitivity is observed more frequently in patients with angioedema than in the healthy population. However, a study with a larger sample is necessary to confirm this finding. 
遗传性血管性水肿(HAE)是一种罕见的常染色体显性遗传病,由C1酯酶抑制剂(C1- inh)缺乏或功能障碍引起。在有关遗传性血管性水肿相关疾病的研究中,与健康人群相比,过敏性疾病的发生率更高,但尚未开展相关研究。本研究是为了确定遗传性血管性水肿患者特应性敏感性和过敏性疾病共病的频率。研究纳入了2019年至2021年期间在梅尔辛市医院儿科过敏综合诊所诊断为遗传性血管性水肿的32例患者。在这些患者中,从他们的档案中获得有关特应性疾病存在的信息并进行记录。哮喘6例(18.8%),变应性鼻炎18例(46.9%),荨麻疹2例(6.2%),未见皮炎。Fx5检测阳性5例(15.6%),吸入性变应原混合物sps IgE检测阳性7例(25.9%)。IgE≥100者12例(52.2%),嗜酸性粒细胞≥4%者16例(50%)。总之,我们推测在本研究中,特应性疾病和特应性敏感性的关联在血管性水肿患者中比在健康人群中更常见。然而,需要更大样本的研究来证实这一发现。

Attitudinal barriers can be more frequent than structural barriers in depression treatment. Understanding attitudinal barriers are the first step to overcome. We aimed to investigate the relationship between the beliefs about depression, antidepressants with attachment styles, and personality characteristics. A total of 207 participants completed an online survey which consisted of the sociodemographic data form, beliefs about antidepressants and depression questionnaire, Experiences in Close Relationships-Revised, and Ten Item Personality Inventory. False beliefs about depression were related to younger age, lower education level, and male gender (p<0.05 each). False beliefs about antidepressants were related to openness to experience personality dimension and anxious attachment style in addition to the male gender and, lower educational level (p<0.05 each). Interventions addressing wrong beliefs about depression should provide basic information about the disease. Clinicians aiming to provide proper knowledge about antidepressants should prioritize a trusting relationship.
在抑郁症治疗中,态度障碍比结构障碍更常见。理解态度障碍是克服的第一步。本研究旨在探讨抑郁信念、抗抑郁药的依恋类型与人格特征之间的关系。共有207名参与者完成了一项在线调查,包括社会人口学数据表、关于抗抑郁药和抑郁的信念问卷、亲密关系经历-修订和十项人格量表。抑郁症错误信念与年龄、文化程度、男性相关(p<0.05)。对抗抑郁药物的错误信念除与男性性别、低文化程度有关外,还与经验人格维度开放性、焦虑依恋类型有关(p<0.05)。解决关于抑郁症的错误观念的干预措施应该提供有关该疾病的基本信息。旨在提供抗抑郁药物正确知识的临床医生应该优先考虑建立信任关系。

This study aimed to investigate the relationship between pain severity and depression level and quality of life in elderly patients with chronic non-specific low back pain (CNLBP) and determine the effect of age group on the quality of life, pain severity and depression symptom levels of patients. Evaluation parameters were obtained using scales specific to geriatric patients. Pain severity, depression, and quality of life were evaluated using the Geriatric Pain Measure (GPM), Geriatric Depression Scale (GDS), and World Health Organization Quality of Life Questionnaire-Older Adults Module (WHOQOL-OLD), respectively. The study included a total of 231 patients with CNLBP (age ≥65 years), of whom 62.3% (n=144) were female and 37.7% were male (n=87). There was a moderate correlation between the patients’ GDS and GPM scores (r=0.53; p<0.05). GDS also had a moderate correlation with the ‘past-present-and-future activities’ (r=-0.52) and ‘social participation’ (r=-0.48) subdomains of WHOQOL-OLD (p<0.05). According to age groups, the only statistically significant difference was observed in ‘sensory abilities’ (p<0.05). Quality of life is negatively affected by the level of depression and pain intensity in elderly individuals with CNLBP. Evaluation of pain severity and depressive symptom levels in elderly patients with CNLBP may contribute to the establishment of an elderly population with improved quality of life and treatment approach. There is a need for further studies to reveal the reasons for poorer quality of life and increased depression and pain.
本研究旨在探讨老年慢性非特异性腰痛(CNLBP)患者疼痛严重程度与抑郁水平及生活质量的关系,确定年龄对患者生活质量、疼痛严重程度及抑郁症状水平的影响。评估参数采用针对老年患者的量表获得。分别使用老年疼痛量表(GPM)、老年抑郁量表(GDS)和世界卫生组织生活质量问卷-老年人模块(WHOQOL-OLD)对疼痛严重程度、抑郁和生活质量进行评估。研究共纳入231例CNLBP患者(年龄≥65岁),其中62.3% (n=144)为女性,37.7% (n=87)为男性。患者GDS与GPM评分之间存在中度相关性(r=0.53;p < 0.05)。GDS与WHOQOL-OLD的“过去-现在和未来活动”子域(r=-0.52)和“社会参与”子域(r=-0.48)也有中度相关性(p<0.05)。按年龄组划分,仅有“感觉能力”有统计学差异(p<0.05)。老年CNLBP患者的抑郁水平和疼痛强度对生活质量有负面影响。评估老年CNLBP患者的疼痛严重程度和抑郁症状水平可能有助于建立具有改善生活质量和治疗方法的老年人群。需要进一步的研究来揭示生活质量下降、抑郁和疼痛增加的原因。

Gastric (foveolar) metaplasia (GM) in the duodenum occurs in many cases where duodenitis develops histologically. However, few studies have investigated the presence of GM in celiac patients. This study aimed to determine the prevalence of GM and its relationship with clinicopathological parameters in untreated pediatric celiac patients. Duodenal biopsy specimens of 153 pediatric cases were analyzed. MUC5AC immunohistochemical staining was applied to all cases to detect GM. The patient group was evaluated in terms of the disease activity score (DAS), neutrophilic activity score (NAS), eosinophilic infiltration, and presence of intramucosal Brunner glands. The rate of GM was 53.4% in the control group and 98.8% in the patient group. GM was observed as diffuse morphology at a rate of 4.1% (n:3) in the control group and 55% (n:44) in the patient group (p<0.001). Diffuse type of GM was more frequent in girls in the patient group (p=0.03). When GM (focal/diffuse) age, DAS, NAS, and all histopathological parameters were compared, a statistically significant difference was found between diffuse GM and DAS, and NAS. (p=0.023 and p=0.039, respectively). The present study considered that duodenal neutrophilia and increased disease activity might play a role in the development of GM in celiac patients. We think that it would be appropriate to include a diffuse type of GM, which can be easily detected by immunohistochemical or histochemical methods, in pathology reports as a finding of histologically active celiac disease.
胃(小窝)化生(GM)发生在十二指肠炎的许多病例中。然而,很少有研究调查转基因在乳糜泻患者中的存在。本研究旨在确定未经治疗的小儿乳糜泻患者中GM的患病率及其与临床病理参数的关系。对153例小儿十二指肠活检标本进行分析。所有病例均采用MUC5AC免疫组化染色检测GM。对患者组进行疾病活动性评分(DAS)、嗜中性粒细胞活动性评分(NAS)、嗜酸性粒细胞浸润、粘膜内布鲁纳腺的存在等评价。对照组GM率为53.4%,患者组GM率为98.8%。对照组为4.1% (n:3),患者组为55% (n:44),呈弥漫性形态学(p<0.001)。弥漫性GM在患者组中以女孩多发(p=0.03)。当比较GM(局灶性/弥漫性)年龄、DAS、NAS和所有组织病理学参数时,弥漫性GM、DAS和NAS之间存在统计学差异。(p=0.023, p=0.039)。本研究认为,十二指肠中性粒细胞增多和疾病活动性增加可能在乳糜泻患者发生GM的过程中起作用。我们认为将弥漫性GM作为组织学活动性乳糜泻的病理报告纳入是合适的,因为它可以通过免疫组织化学或组织化学方法很容易检测到。

The Role of Serum Cadmium Levels in the Etiology of Premature Ovarian Failure: A Case-Control Study 血清镉水平在卵巢早衰病因学中的作用:一项病例对照研究
Pub Date : 2023-02-07 DOI: 10.20515/otd.1190726

Premature ovarian failure (POF) is a clinical syndrome known to affect approximately 1% of women of reproductive age. A number of genetic, autoimmune, metabolic, infectious and environmental causes have been identified in the etiology of POF. Cadmium is a toxic metal which can accumulate in ovaries and causes a significant decrease in the binding of gonadotropins that regulate steroidogenic enzyme activity in granulosa cells. We aimed to investigate the role of cadmium in the etiology of POF. Thirty-five patients with POF were enrolled in group 1 which was the study group. Two control groups were formed from healthy participants. Thirty-fiveparticipants who were age-matched young women with regular menstruation were included in group 2.Thirty-fivehealthy postmenopausal women were included in group 3. Patients' demographic data were recorded. Serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), thyroid-stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4) and cadmium levels were measured. There was a statistically significant difference between the groups for gravida, parity and living children (p<0.001), but no difference was found for abortion (p=0.430). While there was a statistically significant difference between the groups for serum FSH, LH and E2 levels (p<0.001), no statistically significant difference was found for T3, T4 and TSH. Serum cadmium levels were found to be statistically significantly decreased in group 1 compared to g roups 2 and 3 (p<0.001). This study revealed that cadmium had no direct effect on the development of POF, but it should be kept in mind that the synergistic and antagonistic effects of metals may affect this result.
卵巢早衰(POF)是一种临床综合征,已知影响约1%的育龄妇女。许多遗传、自身免疫、代谢、感染和环境因素已被确定为POF的病因。镉是一种有毒金属,可在卵巢中积累,并导致颗粒细胞中调节类固醇生成酶活性的促性腺激素结合显著减少。我们的目的是研究镉在POF病因学中的作用。35例POF患者被纳入第一组,即研究组。两个对照组由健康的参与者组成。35名年龄匹配、月经规律的年轻女性被纳入第二组。35名健康绝经后妇女被纳入第三组。记录患者的人口统计数据。测定血清促卵泡激素(FSH)、促黄体生成素(LH)、雌二醇(E2)、促甲状腺激素(TSH)、三碘甲状腺原氨酸(T3)、甲状腺素(T4)和镉水平。妊娠、胎次、活儿组间差异有统计学意义(p<0.001),流产组间差异无统计学意义(p=0.430)。两组间血清FSH、LH、E2水平差异有统计学意义(p<0.001), T3、T4、TSH水平差异无统计学意义。与2、3组相比,1组血清镉水平显著降低(p<0.001)。本研究表明,镉对POF的发展没有直接影响,但需要注意的是,金属的协同和拮抗作用可能会影响这一结果。

While there was a statistically significant difference between the groups for serum FSH, LH and E2 levels (p<0.001), no statistically significant difference was found for T3, T4 and TSH. Serum cadmium levels were found to be statistically significantly decreased in group 1 compared to g roups 2 and 3 (p<0.001). This study revealed that cadmium had no direct effect on the development of POF, but it should be kept in mind that the synergistic and antagonistic effects of metals may affect this result.","PeriodicalId":409662,"journal":{"name":"OSMANGAZİ JOURNAL OF MEDICINE","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131998838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nosocomial bloodstream infections are common in intensive care units, and a significant portion results in mortality. Procalcitonin is a biomarker used in the early diagnosis of bloodstream infections. Since different pathways release it, its level in the blood may differ in bloodstream infections caused by different agents. The present study was designed to demonstrate whether procalcitonin was an accurate marker in nosocomial bloodstream infections caused by Acinetobacter spp. The present study evaluated 214 bacteremia episodes of 145 patients diagnosed with nosocomial bloodstream infection. Nosocomial bloodstream infection agents were divided into four groups gram-positive bacteria, gram-negative bacteria, Acinetobacter spp., and Candida spp. At the time of diagnosis, procalcitonin, C-reactive protein, neutrophil/lymphocyte ratio, and leukocyte values were measured on the 3rd and 7th days. The mean procalcitonin value measured at the time of diagnosis was 11.7±21.8 ng/ml, the highest in the gram-negative bacteria group. The mean procalcitonin value in the gram-positive bacteria group was 2.8±6.44 ng/ml, 2.5±3.35 ng/ml in the Candida spp. group, and 3.5±12.1 ng/ml in the Acinetobacter spp. group. A significant difference was determined between the four groups regarding procalcitonin values. It was determined that the blood procalcitonin level at the time of diagnosis did not increase as expected in Acinetobacter spp.-induced nosocomial bloodstream infections. In this respect, caution should be exercised in the early diagnosis of nosocomial bloodstream infections.
院内血流感染在重症监护病房很常见,其中很大一部分导致死亡。降钙素原是一种用于血液感染早期诊断的生物标志物。由于释放它的途径不同,它在血液中的水平在由不同病原体引起的血液感染中可能会有所不同。本研究旨在证明降钙素原是否是不动杆菌引起的医院血液感染的准确标志物。本研究评估了145例诊断为医院血液感染的214例菌血症发作。将院内血流感染因子分为革兰氏阳性菌、革兰氏阴性菌、不动杆菌和念珠菌4组,诊断时于第3、7天测定降钙素原、c反应蛋白、中性粒细胞/淋巴细胞比值及白细胞值。诊断时降钙素原平均值为11.7±21.8 ng/ml,以革兰氏阴性菌组最高。革兰氏阳性菌组降钙素原平均值为2.8±6.44 ng/ml,念珠菌组为2.5±3.35 ng/ml,不动杆菌组为3.5±12.1 ng/ml。四组之间关于降钙素原值的显著差异被确定。在不动杆菌引起的院内血流感染中,诊断时血液降钙素原水平没有预期的升高。在这方面,在医院血流感染的早期诊断中应谨慎行事。

In the forensic report, whether the injury includes "vascular injury" or not, the life-threatening situation is important for the investigation. In this study, it was aimed to evaluate the vascular injury status and share the data with the literature in cases related to forensic traumatology, which were reflected in the Forensic Medicine Department of Eskişehir Osmangazi University Faculty of Medicine. In the 5-year period between 2015 and 2019, the cases with vascular injury, who applied to the Eskişehir Osmangazi University Faculty of Medicine, Department of Forensic Medicine, were retrospectively analyzed. Report contents and demographic data of the cases were evaluated. It was determined that 52 (1.2%) of 4378 forensic cases evaluated within the scope of the study had vascular injury. 90.3% of the patients with vascular injury were male, they were most frequently in the 19-29 age group, 69.3% of the cases were stab wounds, and the most commonly injured vessel was a.femoralis and its branches (n=11, %21.2). The data obtained in the study were found to be compatible with the literature. It was thought that in-service trainings on this subject were important, especially for emergency room doctors to be more attentive in issuing forensic reports, to take necessary measures to prevent them from being held responsible in cases of vascular injury and other forensic cases, to protect the legal rights of victims.
在法医鉴定报告中,伤情是否包括“血管损伤”、危及生命的情况对调查十分重要。在本研究中,旨在评估血管损伤状况,并与文献分享有关法医创伤的案例数据,这些案例反映在eski奥斯曼加济大学医学院法医学系。回顾性分析2015 - 2019年5年间eski - ehir Osmangazi大学医学系法医学系血管损伤病例。对报告内容和病例人口统计资料进行评价。确定在研究范围内评估的4378例法医病例中有52例(1.2%)存在血管损伤。血管损伤患者中男性占90.3%,以19 ~ 29岁年龄段居多,刺伤占69.3%,最常见的血管损伤为股股肌及其分支(n=11, %21.2)。本研究获得的数据与文献相符。据认为,这方面的在职培训非常重要,特别是对急诊室医生在发布法医报告时更加注意,采取必要措施防止他们在血管损伤和其他法医案件中被追究责任,以保护受害者的合法权利。

Spiral groove entrapment neuropathy is a compression neuropathy that can occur for various reasons due to the superficial course of the radial nerve at the level of the spiral groove. Since repetitive movements play a role in the development mechanism of compression neuropathy, compelling and repetitive movements of the triceps muscle may predispose to spiral groove entrapment neuropathy. In this case, a 61-year-old male patient who developed a low hand after long-term use of a lawnmower is presented. The patient was diagnosed with spiral groove entrapment neuropathy as a result of the physical examination findings performed in our clinic and the requested electroneurophysiological test, magnetic resonance imaging. The patient's motor and sensory deficit completely recovered after 6 weeks as a result of physical therapy and acupuncture treatment.
螺旋沟陷陷神经病是一种压缩性神经病,由于桡神经在螺旋沟水平的浅行,可因各种原因发生。由于重复性运动在压迫性神经病的发展机制中起作用,强迫和重复性的肱三头肌运动可能易导致螺旋沟压陷神经病。在这个病例中,一位61岁的男性患者在长期使用割草机后出现了低掌。根据在我们诊所进行的体格检查和要求进行的神经电生理测试、磁共振成像,患者被诊断为螺旋沟卡压神经病。经物理治疗和针灸治疗6周后,患者的运动和感觉功能完全恢复。

The time of initiating stem cell collection is very important for successful transplantation and is determined according to peripheral blood CD34+ cell count analysed by flow cytometry. In this study, we aimed to find the role of new complete blood count parameters to determine the optimal time of stem cell collection. Eighty-six patients who underwent stem cell mobilization were included in the study. Peripheral blood CD34+ cells and complete blood count were analysed on the same day. Patients with peripheral blood CD 34+ cell counts ≤ 20/μL and > 20/μL were determined as Group 1 and Group 2, respectively. The difference of CBC parameters between 2 groups and the relationship of these parameters with peripheral blood CD34+ cell counts were evaluated. It was found that immature granulocytes ratio, nucleated red blood cells ratio and count were positively correlated with peripheral blood CD34+ cell count and these parameters were significantly different between two groups (P< 0.001, P= 0.011 and P= 0.012, respectively). The new index formulated by using immature granulocytes and nucleated red blood cells ratios was significantly different between two groups (P<0.001), and had the highest diagnostic accuracy to determine the time of stem cell collection (AUC= 0.766). Immature granulocytes and nucleated red blood cells can be used to determine the time of peripheral blood stem cell collection faster and cheaper compared to flow cytometry.
干细胞的起始采集时间对移植的成功与否至关重要,可通过流式细胞术分析外周血CD34+细胞计数来确定。在这项研究中,我们旨在发现新的全血细胞计数参数在确定干细胞收集的最佳时间中的作用。86名接受干细胞动员的患者被纳入研究。同日分析外周血CD34+细胞及全血细胞计数。将外周血cd34 +细胞计数≤20/μL和>≤20/μL的患者分别作为1组和2组。比较两组患者CBC指标的差异及其与外周血CD34+细胞计数的关系。未成熟粒细胞比例、有核红细胞比例和计数与外周血CD34+细胞计数呈正相关,两组间差异有统计学意义(P< 0.001, P= 0.011, P= 0.012)。使用未成熟粒细胞和有核红细胞比例制定的新指标在两组间差异有统计学意义(P<0.001),在确定干细胞采集时间方面具有最高的诊断准确性(AUC= 0.766)。与流式细胞术相比,未成熟粒细胞和有核红细胞可用于测定外周血干细胞收集时间,速度更快,成本更低。
