Mild liver dysfunction in Klinefelter syndrome is associated with abdominal obesity and elevated lipids but not testosterone treatment.

CONTEXT: Klinefelter syndrome (KS) is associated with hypergonadotropic hypogonadism, which contributes to characteristic phenotypical manifestations including metabolic alterations. Extensive research has demonstrated important associations between androgens and liver function. OBJECTIVES: Investigation of the association between metabolic parameters, sex hormones and liver function in males with KS, both treated (T-KS) and untreated (U-KS) and healthy control males. METHODS: A total of 65 KS males were recruited, of which 32 received testosterone replacement therapy (TRT). Also, 69 healthy controls were recruited. We used alanine aminotransferase (ALAT), alkaline phosphatase and PP (prothrombin-proconvertin time ratio) as the main liver markers. Multivariable regression was performed within the three groups. All statistics were calculated using STATA. Principal component analysis was utilized to demonstrate the interconnected patterns among all measured biomarkers, and to elucidate how the different groups were linked to these patterns. RESULTS: Higher levels of main liver markers were observed in U-KS compared to controls, with no significant differences between U-KS and T-KS. T-KS had lower abdominal fat, total cholesterol, and LDL cholesterol than U-KS. Using multivariable models, variation in ALAT in U-KS was explained by HOMA2%S; in T-KS by BMI and SHBG; and in controls by hip circumference and estradiol. We found no multivariable models explaining variation in PP in U-KS; in T-KS, PP was explained by BMI and LDL cholesterol, and in controls by total cholesterol. Using principal component analysis U-KS was positively associated to D1 (an obese profile, which also included ALAT) and controls negatively associated with D1 (non-obese profile). CONCLUSION: KS males have mild liver dysfunction reflected by a significant increase in the main liver markers and decrease in albumin. The presented data underscore a primary role of metabolic conditions including obesity, insulin resistance and unfavourable lipid profile, in the elevated liver function markers seen in males with KS. Whether TRT can improve liver function in KS warrants further studies. Our findings, highlight that an evaluation of the liver function should be part of the clinical care in males with KS.

Analgesic Efficacy of Erector Spinae Plane Block in Pediatric Abdominal Surgery: Guidance with Conventional Method and NOL: Case Series.

Background: Erector spinae plane (ESP) block is a regional anesthesia technique that blocks both somatic and visceral nerve fibers. Despite its high analgesic potential, its mechanism of action is not yet fully understood. The ultrasound-guided ESP block, which can be easily performed, makes important contributions to the control of intraoperative pain in pediatric patients undergoing abdominal surgery. The follow-up of pain in the intraoperative period is usually done by evaluating the changes in hemodynamic parameters. Due to physiological differences in pediatric patients, it is more difficult to do this with only hemodynamic changes than in adult patients. Aim: The NOL® (Nociception Level) monitor calculates the nociception/pain score by evaluating many parameters through a proprietary algorithm. Our primary aim was to demonstrate the effectiveness of ESP block with an advanced pain monitor in this patient group; our secondary aim was to investigate the necessity of pain monitors in the pediatric patient group. Methods: In this case series, we applied intraoperative NOL® monitoring in addition to standard monitoring (ECG, SpO2, heart rate, EtCO2) in pediatric patients (16 cases) who were scheduled for abdominal surgery and underwent ESP block. Results: Considering the hemodynamic data, NOL values, postoperative pain scores, side effects, and complications, it was concluded that ESP block can be used safely in this patient group. Although the hemodynamic data and the NOL® index were compatible with each other after a nociceptive stimulus, the NOL index was less affected by other variables and gave the clinician clearer information about pain.

Effects of Sixty-Minute Race-Pace Running on Cardiac Stress Biomarkers in Recreational Distance Runners.

Sudden cardiac death (SCD) in athletes is generally rare, but a serious complication of cardiovascular events during exercise. Although regular intensive physical exercise is thought to be a key to a healthy life, unsuspected pathologies might lead to SCD during or after physical activity. Cardiac dysfunction and elevated cardiac markers have been reported after prolonged exercise. We sought to clarify the cardiac marker levels and hydration status in healthy, middle-aged male subjects for 24 hours after running sixty-minute at race-pace. The participants were 47.4±1.7 years old, had peak oxygen consumption of 47.1±1.2ml/kg/min, and regularly running 70.5±6.4km/week. Blood biomarkers were performed before, immediately after, at the fourth and twenty-fourth hours after running. Compared to initial values, creatine kinase (before:161.2±22.5U/L, 24 hours after:411.9±139.7U/L, p<0.001) and CK-MB (before:4.3±0.7ng/ml, 24 hours after:10.1±3.0ng/ml, p<0.001) were significantly elevated immediately after running and remained significantly high for 24 hours. In addition, Troponin-I (before:5.0±1.1ng/l, 4 hours after:81.5±29.9ng/l, p<0.001) and NT-proBNP (before: 31.2±5.3pg/ml, immediately after: 64.4±8.5pg/ml, p<0.01) were significantly elevated immediately after running and returned to baseline levels in 24 hours. The sixty-minute running caused significant dehydration, but athletes were rehydrated at the 4th hour in their voluntary hydration behavior. As the individual data were analyzed, it was interesting to see that some of the athletes had critical biomarker levels without any cardiac symptom. Our findings indicate that race-pace sixty-minute running may induce a possible transient silent myocardial injury in apparently healthy master runners. Detailed pre-participation screening of these athletes may be necessary to reduce the risk of SCD.

The role of interventional pulmonology for the postoperative bronchopleural fistula.

BACKGROUND: : Postoperative bronchopleural fistula (BPF) remains a serious complication due to its high morbidity and mortality. Although various endoscopic techniques have been defined for the closure of BPF previously, no standard algorithm yet exists. AIMS: To study the effectiveness and safety of various endoscopic procedures in an interventional pulmonology unit. MATERIALS AND METHODS: The medical data of 15 postoperative BPF patients, who were undergone endoscopic intervention were retrospectively investigated. RESULTS: The mean size of the fistulas determined by bronchoscopic evaluation was 7.93 ± 3.26 mm (range 3-15 mm). Applied procedures were as follows: stent implantation (n: 8, 53.3%), stent implantation and polidocanol application (n: 4, 26.7%), only Argon Plasma Coagulation (APC) application (n: 2,13.3%), polidocanol application (n: 1,6.7%). Complete fistula closure was achieved in three of the 15 patients (20%). The procedures were partly successful in five (33.3%) patients and failed to be successful in seven (46.6%) patients. Survival rates in regard to procedural success were determined and a statistically significant difference was found in five-year survival rates (P = 0.027, P < 0.05). CONCLUSION: Our results demonstrated that bronchoscopic procedures can be safely and effectively performed in patients who were not eligible for surgery for various reasons.

Readability of online patient education material for the novel coronavirus disease (COVID-19): a cross-sectional health literacy study.

OBJECTIVES: The internet has become one of the most important resources for the general population when searching for healthcare information. However, the information available is not always suitable for all readers because of its difficult readability. We sought to assess the readability of online information regarding the novel coronavirus disease (COVID-19) and establish whether they follow the patient educational information reading level recommendations. STUDY DESIGN: This is a cross-sectional study. METHODS: We searched five key terms on Google and the first 30 results from each of the searches were considered for analysis. Five validated readability tests were utilized to establish the reading level for each article. RESULTS: Of the 150 gathered articles, 61 met the inclusion criteria and were evaluated. None (0%) of the articles met the recommended 5th to 6th grade reading level (of an 11-12-year-old). The mean readability scores were Flesch Reading Ease 44.14, Flesch-Kincaid Grade Level 12.04, Gunning-Fog Index 14.27, Simple Measure of Gobbledygook SMOG Index 10.71, and Coleman-Liau Index 12.69. CONCLUSIONS: Online educational articles on COVID-19 provide information too difficult to read for the general population. The readability of articles regarding COVID-19 and other diseases needs to improve so that the general population may understand health information better and may respond adequately to protect themselves and limit the spread of infection.

Venom allergy and knowledge about anaphylaxis among beekeepers and their families.

BACKGROUND: Beekeepers and their families are at an increased risk of life-threatening anaphylaxis due to recurrent bee-sting exposures. OBJECTIVE: The aim of this study is to evaluate the demographic features, previous history of anaphylaxis among beekeepers and their family members, and their knowledge about the symptoms and management of anaphylaxis. METHODS: A standardized questionnaire was administered to beekeepers during the 6th International Beekeeping and Pine Honey Congress held in 2018, in Mugla, Turkey. Additionally, food-service staff from restaurants were surveyed as an occupational control group about their knowledge about anaphylaxis. RESULTS: Sixty-nine beekeepers (82.6% male, mean age 48.4±12.0 years) and 52 restaurant staff (46.2% male, mean age 40.5±10.0 years) completed the questionnaire. Awareness of the terms 'anaphylaxis' and 'epinephrine auto-injector' among the beekeepers were 55.1% and 30.4% and among the restaurant staff were 23.1% and 3.8%, respectively. Of the beekeepers, 74% were able to identify the potential symptoms of anaphylaxis among the given choices; 2.9% and 5.8% reported anaphylaxis related to bee-stings in themselves and in their family members, respectively. None of the restaurant staff had experienced or encountered anaphylaxis before but 3.8% of their family members had anaphylaxis and those reactions were induced by drugs. CONCLUSION: It is essential that implementation of focused training programs about anaphylaxis symptoms and signs as well as practical instructions of when and how to use an epinephrine auto-injector will decrease preventable morbidities and mortalities due to bee-stings in this selected high-risk population of beekeepers and their family members, as well as other fieldworkers under risk.

Comparison of delivery characteristics and early obstetric outcomes between Turkish women and Syrian refugee pregnancies.

BACKGROUND: Until September 1, 2016, Turkey hosted around 2.7 million Syrian refugees. However, data investigating the pregnancy health concerning the refugees are still limited. AIM: In the present study, we aimed to compare the delivery characteristics and short-term obstetric outcomes in Turkish women and Syrian refugees. SUBJECTS AND METHODS: The study included 1556 singleton pregnancies which comprised 940 Turkish women and 616 Syrian women between January 2016 and January 2017. The groups were compared for demographic data, obstetric features, and pregnancy outcomes. RESULTS: There were significant differences between Turkish women and the refugees in terms of preterm (18.94% vs. 11.00%, P = 0.003) and post-term delivery rates (11.49% vs. 2.91%, P < 0.001), caesarian delivery rates (33.4% vs. 23.95%, P = 0.002), newborn weights <1000 g (2.55% vs. 0.97%, P = 0.006) and >4000 g (5.32% vs. 3.24%, P = 0.006), pre-eclampsia (5.32% vs. 1.62%, P = 0.009), HELLP (1.28% vs. 0.00%, P = 0.046), and placental anomalies (1.91% vs. 0.00%, P = 0.014), respectively. Being a Turkish resident (P = 0.015) was an important risk factor for the development of unfavorable pregnancy outcomes. Moreover, maternal education of at least 12 years (P = 0.028) and receiving a regular antenatal visit at a tertiary center (P = 0.031) were preventative for the development of unfavorable pregnancy outcomes. Adverse pregnancy outcomes were less prevalent in Syrian refugees compared to that in the Turkish residents which was likely due to the contribution of maternal education and regular antenatal visits which were higher in Syrian refugees. CONCLUSIONS: We suggest that providing adequate education particularly for women in undeveloped countries and facilitating access to the tertiary hospitals have the potential to reduce unfavorable pregnancy outcomes in immigrant women.

Changes in substrate utilization rates during 40 min of walking within the Fatmax range.

BACKGROUND AND AIMS: The aim of this study was to evaluate changes in fat oxidation rate during 40 min of continuous exercise and identify the intensity at the highest fat oxidation rate (Fatmax). METHODS: A total of 14 sedentary males with age, body height, weight, and BMI averages of 29.3 ± 0.7 years, 178.3 ± 1.7 cm, 81.1 ± 3.9 kg, and 25.4 ± 0.9 kg/m2, respectively, were included in the study. Fatmax was determined using an indirect calorimeter with an incremental treadmill walking test at least after 12 h of fasting. On a separate day, at least after 12 h of fasting, the participants walked for 40 min within their predetermined individual Fatmax heart rate and speed ranges. RESULTS: The initial fat oxidation rate was not sustained within the first 16 min of exercise and was reduced; however, carbohydrate oxidation reached a stable level after nearly 10 min. CONCLUSIONS: In sedentary individuals, during low-intensity physical activity, fat oxidation rates may not be sustainable as expected from Fatmax testing. Therefore, when exercise is prescribed, one should consider that the fat oxidation rate might decrease in sedentary overweight individuals.

Alteration in humoral immunity is common among family members of patients with common variable immunodeficiency.

BACKGROUND: The prevalence of primary immunodeficiency (PID) in the relatives of patients with common variable immunodeficiency (CVID) and IgA deficiency is high. Allergic disorders have been recorded in patients with humoral immunodeficiency. We aimed to determine the frequency of humoral immunodeficiency and atopy in the relatives of patients with CVID. METHODS: The study population comprised 20 CVID patients and their relatives. All relatives were screened using a questionnaire covering demographic characteristics, warning signs of PID (adults and children), and core questions on asthma, rhinitis, and eczema from the International Study of Asthma and Allergies in Childhood (ISAAC). We also recorded absolute neutrophil and lymphocyte counts, serum immunoglobulin levels, pulmonary function values, and skin prick test results. RESULTS: The study sample comprised 20 patients with CVID (15 males, 5 females; mean (SD] age, 16.4 (9] years) and 63 first-degree relatives (18 mothers, 16 fathers, 16 sisters, 10 brothers, and 3 offspring). The rate of parental consanguinity was 75%. Of 17 family members with positive PID warning signs, 6 had concomitant hypogammaglobulinemia (3 low IgM levels, 2 selective IgA deficiency, and 1 partial IgA deficiency). The ISAAC questionnaire revealed allergic rhinitis in 3 mothers, asthma in 2 fathers, and 1 sibling. Skin prick testing revealed sensitization to aeroallergens in 31.6% of cases in addition to 1 parent and 1 sibling. CONCLUSIONS: Almost half of the 20 families with a CVID patient had at least 1 additional member with hypogammaglobulinemia, leading us to recommend routine screening for relatives of CVID patients.

Unusual localization of a primary hydatid cyst: a subcutaneous mass in the paraumbilical region.

Hydatid cyst disease caused by Echinoccus granulosus is not a rare disease and mostly localized in liver and lung. The localization of the disease in the subcutaneous paraumbilical region without any other organ involvement is a unique existence that we present. A 63-year-old Turkish male complaining of abdominal distention and pain had an abdominal mass for one year. When the patient came to our Clinic, we detected a 4x5 cm mass in the left quadrant- paraumbilical region by using ultrasonography. Complete surgical resection of the mass was performed with uneventful post-operative recovery. Histopathological examination of the surgical specimen demonstrated a multive-sicular hydatid cyst. When a subcutaneous cystic mass is detected in a patient, regarding the region where he lives and endemicity, hydatid cyst should be considered.

The effect of Amifostine (Ethyol) on intestinal anastomosis in rats with radiation enteritis.

BACKGROUND: Preoperative radiotherapy in colorectal cancers is being used as an adjuvant therapy with increasing frequency. Postoperative complications in early and late periods in various ratios are reported. It has also been shown that radiation has a delaying effect on wound healing and this effect is dose-dependent. AIM: This study investigated the effects of the Amifostine on healing of the irradiated colonic anastomosis. MATERIALS AND METHODS: 30 female Wistar rats were divided randomly into three groups equally (n=10). Colonic anastomosis were performed to all rats. Group I served as a control. 800 rad abdominopelvic irradiation on the 5th day of preoperation was given to group II and III. Rats in the group III, prior to radiation, were given Amifostine at a dose of 200 mg/kg. On the 5th postoperative day all the rats were sacrificed and the healing of anastomosis was measured with bursting pressure, hydroxyproline levels and histopathological evaluations. Statistical analyses were expressed by analysis of variance (ANOVA) test and p < 0.05 was regarded as significant. RESULTS: In group II, all parameters were found lower compared with control group and Amifostine+Radiation group. As compared with hydroxyproline values and the anastomotic wound healing scores, except group II, no significantly difference were determined between the two other groups. In bursting pressure levels, Group I and III were higher than group II, but not statistically significant (p > 0.05). In group III (Amifostine+Radiation group), the hydroxyproline levels and anastomotic wound healing scores were found significantly higher than group II (p < 0.05), and no significant difference were found between the control group. CONCLUSIONS: It is determined that radiation given on the 5th preoperative day has a negative effect on anastomotic wound healing and administered Amifostine prevent this negative effect. In the light of these data, the Amifostine may have a positive effect on preoperative irradiated colonic anastomosis and may play an important role in future on the supporting of the colonic anastomosis.

Assessing eco-toxicological effects of industrial 2,4-D acid iso-octylester herbicide on rat pancreas and liver.

We studied the eco-toxic and carcinogenic effects of a commonly used 2,4-D acid iso-octylester herbicide on rat liver and pancreas. The rats in Group 1 were fed a standard feed and the rats in Group 2 were fed with standard feed to which was added 200 mg/kg/day 2,4-D acid iso-octylester for 16 weeks. Azaserine, 30 mg/kg/body weight, was injected into rats of Groups 3 and 4 to investigate the effects of 2,4-D acid iso-octylester on the development of neoplasms. After feeding the rats with neoplasms in Group 4 with food including 200 mg/kg/day 2,4-D acid iso-octylester for 16 weeks, an autopsy was carried out on all animals. We found that 2,4-D acid iso-octylester caused the formation of atypical cell foci (ACF) in the pancreata and livers of rats. ACF that were formed experimentally by exposure to azaserine had increased diameter, volume and number of atypical cell foci/mm(2) and mm(3) after exposure to 2,4-D acid iso-octylester. Our observations indicated that this herbicide potentially is a cancer initiator.

A delayed hypersensitivity reaction to a stainless steel crown: a case report.

Stainless steel crowns are commonly used to restore primary or permanent teeth in pediatric restorative dentistry. Here, we describe a case of a delayed hypersensitivity reaction, which manifested itself as perioral skin eruptions, after restoring the decayed first permanent molar tooth of a 13-year-old Caucasian girl with a preformed stainless steel crown. The eruptions completely healed within one week after removal of the stainless steel crown. The decayed tooth was then restored with a bis-acryl crown and bridge. Since no perioral skin eruptions occurred during the six-month follow-up, we presume that the cause of the perioral skin eruptions was a delayed hypersensitivity reaction, which was triggered by the nickel in the stainless steel crown.

[ARIA (Allergic Rhinitis and its Impact on Asthma) achievements in 10 years and future needs]. / ARIA (allerjik rinit ve astim üzerine etkisi) 10 yildaki kazanimlar ve gelecekteki gereksinimler.

Allergic rhinitis and asthma represent global health problems for all age groups. Asthma and rhinitis frequently co-exist in the same subjects. Allergic Rhinitis and its Impact on Asthma (ARIA) was initiated during a World Health Organization (WHO) workshop in 1999 and was published in 2001. ARIA has reclassified allergic rhinitis as mild/moderate-severe and intermittent/persistent. This classification schema closely reflects the impact of allergic rhinitis on patients. In its 2010 Revision, ARIA developed clinical practice guidelines for the management of allergic rhinitis and asthma co-morbidities based on GRADE (Grading of Recommendation, Assessment, Development and Evaluation). ARIA has been disseminated and implemented in over 50 countries of the world. In Turkey, it is important to make a record of ARIA achievements and to identify the still unmet clinical, research and implementation needs in order to strengthen the 2011 EU Priority on allergy and asthma in children.

Mechanisms of immunotherapy to wasp and bee venom.

Hymenoptera venoms are important allergens that can elicit both local and systemic allergic reactions, including life-threatening anaphylaxis. Venom immunotherapy (VIT) remains the most effective treatment, reducing the risk of systemic reactions in individuals with Hymenoptera venom allergy. VIT can restore normal immunity against venom allergens and provide patients with a lifetime of tolerance to venoms. During VIT, peripheral tolerance is induced by the generation of allergen-specific regulatory T (Treg) cells, which suppress proliferative and cytokine responses against the venom allergens. Treg cells are characterized by IL-10 secretion that directly or indirectly influence effector cells of allergic inflammation, such as mast cells, basophils and eosinophils. Treg cells also have influence on B cells, suppressing IgE production and inducing the production of blocking type IgG4 antibodies against venom allergens. An accumulating body of evidence suggests that Treg cells may affect allergen sensitization and methods for enhancing this cell population may eventually improve the efficacy of VIT. In this article, immune mechanisms enrolled in bee and wasp VIT are reviewed.

Treatment and clinicopathologic predictors for adenoid cystic carcinomas of the head and neck.

PURPOSE: To retrospectively evaluate the management and clinicopathologic predictors of outcome of adenoid cystic carcinoma (ACC) patients treated and followed at our Department. METHODS: Data on 41 patients treated between 2000 and 2006 at the University of Istanbul, Institute of Oncology, were reviewed. Factors affecting recurrence, distant metastasis and survival were evaluated. RESULTS: There were 22 (53.6%) major salivary and 19 (46.3%) minor salivary gland tumors. Eighteen patients (43.9%) had solid histologic type tumor. Twenty-one (51%) patients had perineural invasion and 28 (68.2%) high grade tumors. Sixteen (39%) patients had stage I disease, 12 (29.1%) stage II and 13 (31.5%) stage III. Thirty-two patients (78.4%) had radical and 9 (21.9%) partial resection. Thirty-one patients (75.6%) received adjuvant postoperative radiotherapy (RT). Eight patients (19.5%) suffered locoregional relapse and 9 (21%) distant metastases. Two patients (4.8%) died from ACC and 7 (17%) from other causes. The median follow-up was 48 months (range 24-60). Disease free survival (DFS) at 2 and 3 years were 78% and 58%, respectively. Overall survival (OS) at 2 years and 3 years were 87% and 80%, respectively. Median time to locoregional relapse and distant metastasis was 28 and 32 months, respectively. Seven of 9 patients with distant metastasis had solid tumor subtype. Distant metastasis occurred more frequently in patients with tumors of major salivary glands (66%). Sites of distant metastasis were lung alone (n=5), bone alone (n=2) and 2 patients had both lung and bone metastasis. There was no statistically significant relationship between clinical T stage and solid histology with locoregional relapse (p <0.05). Surgical resection type and perineural invasion were significant prognostic factors for locoregional relapse (p=0.03). T stage (p=0.001), grade (p=0.02) and solid histology (p=0.003) were prognostic factors associated with DFS. Prognostic factors associated with OS were grade (p= 0.001), clinical T stage (p=0.02), solid histology (p=0.01), radical excision (p=0.04) and perineural invasion (p=0.001). CONCLUSION: ACC is a neoplasm in which early diagnosis is important because it is a slow-growing tumor producing diffuse invasion. Distant metastasis and locoregional relapse can be predicted by solid histologic subtype, high grade, type of surgery, perineural invasion and tumor stage. The most frequent sites of metastasis are lung and bone.

Efficacy of intravenous immunoglobulin treatment in children with common variable immunodeficiency.

BACKGROUND: Children with common variable immunodeficiency (CVID) have increased susceptibility to infections. OBJECTIVE: We evaluated the role of intravenous immunoglobulin (IVIG) replacement therapy on the clinical outcome of patients with CVID. METHODS: We studied children diagnosed with CVID and treated with IVIG (500 mg/kg every 3 weeks). RESULTS: The study population comprised 29 children with CVID (mean [SD] age, 11.8 [6.1] years) with at least 1 year of follow-up before IVIG replacement therapy. Mean follow-up duration was 5.6 (3.5) years (range, 15 months-14 years). During therapy, median serum IgG levels increased from 410 to 900 mg/dL. The mean number of respiratory infections per patient per year decreased significantly from 10.2 to 2.5. The annual number and length of hospital stays decreased significantly from 1.36 to 0.21 and 16.35 to 6.33 days per patient, respectively. The mean annual number of antibiotics used decreased significantly from 8.27 to 2.50 per patient. Twelve patients had developed bronchiectasis before initiation of IVIG; 3 patients were cured of this condition. Age at diagnosis, diagnostic delay, number of respiratory tract infections, and number of antibiotics were found to be significantly higher in patients with bronchiectasis, as was lower B-cell percentage. However, gastrointestinal involvement due to noninfectious causes did not improve significantly after IVIG replacement therapy. CONCLUSION: CVID patients treated with IVIG (500 mg/kg every 3 weeks) had satisfactory serum IgG levels, fewer respiratory tract infections, fewer and shorter hospital stays, and reduced antibiotic usage. However, no effect on gastrointestinal involvement was observed. Early IVIG replacement therapy is important in preventing bronchiectasis.
