The Relationship of Anatomical Localizations of Hiatal Clamp and Oesophagogastric Junction with Body Mass Index / Relación entre las Localizaciones Anatómicas de la Pinza Hiatal y la Unión Esofagogástrica con el Índice de Masa Corporal

SUMMARY: In our study, we aimed to reveal the relationship between the anatomical localizations measured and the Body Mass Index (BMI) in patients scheduled for upper gastrointestinal endoscopy. In this study, anatomical localizations of the hiatal clamp and oesophagogastric junction in 189 female and 137 male patients who applied to the hospital with different gastrointestinal system complaints and underwent esophagogastroduodenoscopy (EGD) were investigated depending on BMI. In addition, the data were compared with the patients' complaints before EGD and the diagnoses they received after EGD. SPSS Statistics 22 (IBM Corp. Turkey) program was used for statistical analysis and p0.05). On the other hand, it was determined that the hiatal clamp distance and the distance of the oesophagogastric junction increased as the height and weight increased (p38. As a result of the study, it can be said that BMI values, hiatal clamp distance and oesophagogastric junction localizations may change in relation to height and weight.

En este estudio, buscamos revelar la relación entre las localizaciones anatómicas y el Índice de Masa Corporal (IMC) en pacientes programados para endoscopía digestiva alta. Se investigaron las localizaciones anatómicas de la pinza hiatal y la unión esofagogástrica en 189 mujeres y 137 hombres que acudieron al hospital con diferentes problemas del sistema gastrointestinal los cuales fueron sometetidos a una esofagogastro- duodenoscopia (EGD) dependiendo del IMC. Además, los datos se compararon con las quejas de los pacientes antes de la EGD y los diagnósticos que recibieron después de la EGD. Se utilizó el programa SPSS Statistics 22 (IBM Corp. Turquía) para el análisis estadístico y el valor de p0,05). Por otro lado, se determinó que la distancia de la pinza hiatal y la unión esofagogástrica aumentaba con la altura y el peso corporal (p38. Como resultado del estudio, se puede decir que los valores de IMC, la distancia de pinzamiento hiatal y las localizaciones de la unión esofagogástrica pueden cambiar en relación con la altura y el peso.

Pregabalin inhibits proinflammatory cytokine release in patients with fibromyalgia syndrome.

Objectives: The main goal of the study was to investigate how pregabalin (PGB) affects proinflammatory cytokine release in patients with fibromyalgia syndrome (FMS). Patients and methods: This experimental research study was conducted with 85 female participants (mean age: 49.6±10.1 years; range, 30 to 73 years) between April 2020 and November 2020. Of the participants, 30 were FMS patients using PGB 150 mg/day for at least three months, 30 were FMS patients not using PGB, and 25 were healthy individuals. The detection of FMS was carried out according to the 2010 American College of Rheumatology diagnostic criteria. Levels of proinflammatory cytokines (interleukin [IL]-2, IL-6, IL-12, IL-17, interferon-gamma, and tumor necrosis factor-alpha) were measured by enzyme-linked immunosorbent assay. Results: Serum concentrations of proinflammatory cytokines were remarkably decreased in FMS patients using PGB (p<0.001) and were higher in patients with FMS not using PGB than in healthy subjects (p<0.001). The highest values of proinflammatory cytokines were found in the group of FMS patients not using PGB (p<0.001). Conclusion: These results indicate that PGB inhibits the release of proinflammatory cytokines, suggesting that it can be used as an anti-inflammatory agent in inflammatory cases.

Carbapenem and Colistin Resistance, Integrons and Plasmid Replicon Types in Multi-Drug Resistant Klebsiella Strains Isolated in Turkey.

BACKGROUND: Multidrug-resistant (MDR) Klebsiella is a globally important nosocomial pathogen. In the present study, 101 multidrug-resistant Klebsiella strains isolated from various clinical specimens obtained from two different Medical Faculties' hospitals were involved. We aimed to find out the prevalence of carbapenemase, mobile colistin resistance genes, and integrons in MDR Klebsiella strains. METHODS: The antibiotic susceptibilities of strains were determined by Kirby Bauer disc-diffusion method and resistance to colistin was confirmed by detection of minimum inhibitory concentrations. The prevalence of carba-penemase genes (blaOXA-48, blaNDM, blaIMP, blaVIM, blaKPC), mobile colistin-resistance genes (mcr-1 and mcr-2), and integrons (class I, II and III) were examined in Klebsiella strains by polymerase chain reaction. RESULTS: All strains were resistant to ß-lactam antibiotics, carbapenems, and quinolones. On the other hand, only nine (8.9%) strains were resistant to colistin. The most common carbapenemase genes were blaNDM (64.3%) and blaOXA-48 (53.5%). Besides, 28 (27.7%) strains were found to harbor both blaNDM and blaOXA-48. These 28 strains be-longed to the IncA/C (18.7%), IncL/M (7.7%), and IncFIIs (1.1%) plasmid replicon types. No strain was positive for blaIMP, mcr-1, and mcr-2. Class I and Class II integrons were shown to be harbored in 83.2% and 63.3% of strains, respectively. In total, 63 (63.6%) of strains harbored both classes I and II integrons. Class III integron was not detected. There was a statistically significant relationship between the presence of integrons and antibiotic resistance for cefotaxime (p = 0.024), ciprofloxacin (p < 0.001) trimethoprim/sulfamethoxazole (p < 0.001) and levofloxacin (p = 0.002). To our knowledge, this study represents the first report of a human isolate for the co-presence of blaNDM, blaOXA-48 and both Class I and Class II integrons, from Turkey. CONCLUSIONS: Our findings also highlight the dissemination of integrons and carbapenemases and the importance of surveillance on emerging antibiotic resistance.

Increased maternal mortality in unvaccinated SARS-CoV-2 infected pregnant patients.

The aim of this study was to demonstrate the poor prognosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in unvaccinated pregnant women. In this retrospective study, the clinical and laboratory parameters of 26 pregnant or immediately postpartum patients, who were hospitalised and needed intensive care unit (ICU) follow-up due to coronavirus disease 2019 (COVID-19) infection were reported. All pregnant patients who followed up in the ICU were unvaccinated. The mortality rate was calculated as 34.62% in the patients included in the study who were admitted to the ICU. Among patients hospitalised in the ICU, the maternal mortality and stillbirth rates associated with COVID-19 infection were found to be 156.28/100,000 and 11.54%, respectively. Preterm birth occurred in 58.33% of the patients who delivered. 79.17% of the patients were delivered by caesarean section. Lymphopenia, high ferritin, interleukin-6, lactate dehydrogenase, D-dimer and C-reactive protein values were found to be associated with mortality. The course of pregnant patients with COVID-19 infection is not always predictable. Clinical and laboratory data should be evaluated in combination for disease prognosis. Adequate information should be given about the importance of vaccination.Impact StatementWhat is already known on this subject? The SARS-CoV-2 infection has caused a public health crisis worldwide. As a result of studies on coronavirus disease 2019 (COVID-19) infected pregnant women, it was observed that there was an increase in maternal and perinatal mortality. There has been an increase in intensive care unit (ICU) admissions, especially after patients infected with the Delta variant. The pandemic continues with an unpredictable course of the new variants.What do the results of this study add? Compared to the pre-pandemic period, COVID-19 infection caused a more than 10-fold increase in maternal mortality, particularly after the Delta variant. In intensive care follow-up, low lymphocyte count, high lactate dehydrogenase, D-dimer, C-reactive protein, ferritin and interleukin-6 values are indicators of poor prognosis.What are the implications of these findings for clinical practice and/or further research? COVID-19 infection causes increased maternal mortality. Considering that all of the patients admitted to the ICU in our study were unvaccinated, pregnant women should be encouraged to get vaccinated.

Do morphologic characteristics play a role in nodal metastatic progression of well-differentiated pancreatic neuroendocrine tumors?

BACKGROUND: Pancreatic neuroendocrine neoplasms (NENs) are tumors with histopathologic and prognostic heterogeneity that pose difficulties in establishing standards for diagnosis, classification, and treatment. Among NENs, well-differentiated neuroendocrine tumors (NETs) have been classified as grade 1, 2, and 3 in the most recently released World Health Organization classification. Although well-differentiated NETs are associated with relatively better prognosis, they have a potential for malignant behavior such as extrapancreatic spread, metastasis, or recurrence. The present study aimed to evaluate clinical and histomorphologic findings of patients with well-differentiated pancreatic NETs and to identify histopathologic findings effective in predicting nodal metastatic progression. METHODS: The study group consisted of 54 patients diagnosed with well-differentiated NET. All preparations and blocks of the patients were examined for the following histopathologic parameters: tumor diameter, microscopic tumor growth pattern (solid, trabecular, acinar, and mixed), cellular features (clear, eosinophilic, oncocytic, peliotic, and pseudopapillary), stromal changes (calcification, lymphocytic infiltration, and stromal hyalinization), presence of necrosis, perineural invasion, lymphovascular invasion, mitotic activity, and Ki67 proliferative index. RESULTS: Lymph node metastasis was present in 7 patients. Lymph node metastasis was significantly associated with tumor diameter of >2 cm (p = 0.012), Ki67 proliferative index of >20% (p = 0.022), grade 3 tumors (p = 0.002), presence of dense stromal hyalinization (p = 0.034), and mild lymphocytic infiltration (p = 0.041). CONCLUSION: The present study revealed that the new findings such as presence of dense stromal hyalinization and absence of remarkable lymphocytic infiltration could be predictive morphologic findings for the development of lymph node metastasis.

The Effect of Hamatum Curvature Angle on Carpal Tunnel Volumetry: A Mathematical Simulation Model.

In carpal tunnel volume measurements, the angle of the hamatum curvature is not considered a variable, and its effect on carpal tunnel volume has not been investigated. We hypothesize that a change in the anatomical angle of the hamatum curvature changes the carpal tunnel volume. To prove our hypothesis, we used a mathematical simulation model considering the carpal tunnel as a truncated cone. We reviewed the wrist CT scans of 91 adults (>18 years of age), including 51 men and 40 women. We measured the angle of the hamatum curvature in the CT scans. We measured cross-sectional areas at the outlet of the carpal tunnel at the level of the trapezium and hook of hamate (r1) and at the inlet at the level of the scaphoid and pisiform (r2) and the length (h) of the carpal tunnel. We attempted to calculate the effect of 2 degree by 2-degree changes in the angle of the hamatum curvature between the angles of 98° and 140° on the carpal tunnel volume. The mean angle of the hook of hamatum of the subjects was 122.55° ± 8.20° (range, 97.20° - 139.31°). No suitable cutoff point was found for the angle values. There was no difference between the gender groups according to the angle value. The data clearly show that there is a high correlation between carpal tunnel volume and the angle of hamatum curvature. The results of our study emphasize the importance of taking into account the anatomical features of the hamatum bone, especially the angle of curvature, which may play a predisposing role in idiopathic carpal tunnel syndrome.

Evaluation of patellar tendon with shear wave elastography after anterior cruciate ligament reconstruction using hamstring tendons.

OBJECTIVES: This study aims to evaluate the characteristics of patellar tendons (PTs) of patients who underwent anterior cruciate ligament reconstruction (ACLR) with hamstring tendon autograft using shear wave elastography (SWE). PATIENTS AND METHODS: This prospective study was conducted between August 2017 and February 2018. We performed brightness mode (B-mode) ultrasound and SWE on 21 patients (20 males, 1 female; mean age 32 years; range, 19 to 42 years) who underwent ACLR with a single-bundle transtibial technique using quadruple hamstring autografts and 14 healthy controls (13 males, 1 female; mean age 35 years; range, 25 to 47 years). Length and thickness of the PT were evaluated with B-mode ultrasound, while elasticity values were evaluated with SWE in the patient and control groups. RESULTS: The mean SWE value of the patient group on the operated side was 25.30 (min-max=16.60-46.20) and on the non-operated side 23.20 (min-max=12.40-44). There were no statistically significant differences regarding PT elasticity, thickness, or length between the groups (p>0.05). CONCLUSION: There were no differences regarding elasticity, length, or thickness between the operated and healthy knees detected with SWE. Upcoming research should focus on tendon biopsy and biochemical analyses for the identification of possible intrastructural changes of the tendon due to collagen synthesis after ACLR with hamstring autograft.

Median nerve and carpal tunnel volume changes after two different surgical methods: A comparative magnetic resonance imaging study of mini-open and endoscopic carpal tunnel release.

OBJECTIVES: This study aims to compare endoscopic carpal tunnel release versus mini-open carpal tunnel release regarding volume changes in the carpal tunnel and median nerve by magnetic resonance imaging (MRI). PATIENTS AND METHODS: The study included 17 wrists of 13 patients (1 male, 12 females; mean age 55 years; range, 51 to 64 years) who were diagnosed with carpal syndrome. Ten wrists underwent mini-open carpal tunnel release, while seven wrists underwent uni-portal endoscopic carpal tunnel release. Carpal tunnel and median nerve volumetric changes were evaluated by MRI pre- and postoperatively. RESULTS: Surgical section of transverse carpal ligament significantly increased the postoperative volume of the carpal tunnel and median nerve compared to preoperative (p<0.05). However, the endoscopic and mini-open carpal tunnel techniques had no superiority over one another regarding volume expansion (p>0.05). CONCLUSION: Both methods can be preferred to release the transverse carpal ligament in patients with idiopathic carpal tunnel syndrome. The surgeon should decide on which method to use considering the advantages and disadvantages reported in the literature.

Laparoscopic versus vaginal cuff closure in laparoscopic hysterectomy: does it affect female sexuality?

OBJECTIVES: To investigate the effect of vaginal cuff closure technique in laparoscopic hysterectomy on vaginal length and female sexual functions. MATERIAL AND METHODS: This study was conducted at a tertiary research hospital. Women who underwent laparoscopic hysterectomy were included and classified according to vaginal cuff closure technique as laparoscopic (n = 75) and vaginal route (n = 25). Vaginal lengths were measured preoperatively and at 6th month postoperatively. Golombok-Rust Inventory of Sexual Satisfaction (GRISS) was used to evaluate female sexual functions. SPSS was used for statistical analysis and the level of significance was p = 0.05. RESULTS: Preoperative GRISS scores and vaginal lengths were similar in two groups. The shortening of vaginal length and the worsening of GRISS scores were more prominent in vaginal cuff closure group (p = 0.002, p < 0.001). The alteration in vaginal length was positively correlated with the alteration in GRISS score in vaginal and laparoscopic route groups (r = 0.800, p < 0.001; r = 0.680, p < 0.001). The risk of female sexual dysfunction increases 69.88 fold for each 1 cm shortening of vaginal length (p = 0.039). Discriminative value of postoperative vaginal length for female sexual dysfunction in patients who underwent laparoscopic hysterectomy was investigated and a cut-off value of 7.4 cm (p < 0.001) was found. CONCLUSIONS: Laparoscopic route instead of vaginal route in laparoscopic hysterectomy is preferable to preserve a better vaginal length, which may be an important factor for female sexual functions.

[Evaluation of asthma awareness among teachers in Bursa]. / Bursa ilindeki ögretmenlerin astim farkindaliginin degerlendirilmesi.

INTRODUCTION: The purpose of this study was to elucidate the asthma knowledge level of primary-secondary school teachers in Bursa, and factors associated with this subject. MATERIALS AND METHODS: In our study 1812 teachers from 64 randomly selected primary schools in Bursa were included. RESULT: It was known by the vast majority of participants that asthma symptoms, asthma is not a contagious disease and may be familial, medications taken by inhalation. It was known by 64.1% of the teachers that asthmatic children do not mind doing sports. Approximately one of the two teachers knew that the medication were not addictive. CONCLUSIONS: The knowledge level of the teachers was related to female gender and age. We think that an asthma education program is needed for Turkish teachers to increase their understanding about what asthma is, its impact and how to meet the needs of a child with asthma to achieve improved wellbeing and school attendance.
