Introduction: Obsessions and compulsions often focus on routine life actions such as consuming, bathing and living in public, so the disorder interferes with the social, family and occupational functioning of both the individual and their caregiver. In OCD, caregivers are often involved in the ritual behaviors of the individual, either by providing avoidance or by assisting in ritual behaviors. Individuals with OCD are often exposed to aggression from family members because of these behaviors. Research has shown that individuals with OCD may experience illness-related domestic violence. In the literature review on the subject, there were no qualitative studies examining the experiences of individuals diagnosed with OCD towards domestic violence caused by the symptoms of the disease. A mix-method study conducted by aimed to explore the illness-related domestic violence experiences of individuals diagnosed with OCD. The study utilized both quantitative and qualitative methods to gather data from individuals with OCD. The findings of the study revealed that a significant number of individuals with OCD reported experiencing domestic violence related to their illness. This study highlights the importance of addressing the issue of domestic violence in individuals with OCD and the need for appropriate interventions and support. Objectives: This study was planned to examine the experiences of individuals diagnosed with OCD regarding domestic violence caused by the symptoms of the disease in Turkey. Methods: The sample of the study was determined by purposive sampling method. The study was conducted with individuals diagnosed with OCD who were being treated in the psychiatric clinics of two university hospitals. The study used mixed methods and was planned in two phases. In the first stage, Socio-Demographic Data Form and Yale-Brown Obsession Compulsion Scale were used. After reviewing the results of these scales, individual in-depth interviews were conducted with 20 patients who had a history of domestic violence and scored above 16 on the Yale Brown Obsessions and Compulsions Scale. Data saturation was deemed to have been reached and data collection was terminated. Results: The analysis of the data is still ongoing in detail by the researchers. The findings and relational implications of the study will be presented. Conclusions: It is thought that the results of the study will provide a basis for further research and intervention programs and contribute to the literature by determining the types of violence experienced by individuals diagnosed with OCD from family members due to the disease, how patients feel in the face of the problems they experience and how they cope with it. In addition, the results of the study are expected to help intervention programs to be developed for families to strengthen treatment adherence.

Abstract Background The role of free oxygen radicals in inflammatory conditions is well known. Free radicals cause lipid peroxidation of cellular membranes resulting in cell death. The purpose of this study was to investigate the levels of total anti-oxidant status (TAS), as a marker of anti-oxidant defense system and malondialdehyde (MDA), as a marker of oxidative stress, in the plasma of patients with acute appendicitis. Methods Fifty-one adult patients with a median age of 31 years who underwent operations with a preoperative diagnosis of acute appendicitis were included in this prospective study. Blood samples for C-reactive protein (CRP), MDA and TAS were collected preoperatively. Groups were compared by using the Mann-Whitney U test. Results There were 27 patients with acute phlagmenous appendicitis and 19 patients with advanced appendicitis (10 gangrenous and 9 perforated appendicitis), while 5 negative explorations were documented. No significant differences in WBC counts and MDA levels between groups were encountered. Plasma CRP was significantly higher in patients with perforated appendicitis, but not in the other groups. In advanced appendicitis group, TAS level was significantly lower than the other groups. On the other hand, plasma TAS level in acute phlagmenous appendicitis group was significantly higher. Conclusion A decrease in plasma total anti-oxidant capacity might be a predictor of the progression of inflammation to the perforation in acute appendicitis.

Study Design: Retrospective study., Objection: There can be a relationship between degenerative diseases in the spine and hip., Summary of Background Data : Degenerative diseases in the spine and hip may occur concomitantly. This study was done to investigate the cross-sectional area of psoas muscle size and incidence of lumbar disc herniation after unilateral hip arthroplasty., Methods: The data files of patients who were operated on for unilateral hip arthroplasty between January 2014- and 15 May 2021 at the Recep Tayyip Erdogan University Hospital were retrospectively analysed for the relationship between the psoas muscle volume and the incidence of lumbar disc herniation. The patients were divided according to their operated sides., Results: The data files of 48 patients were retrospectively analysed. The patients were divided into two groups according to the operated side of their hip joints. Gender and age differences were not significant, and the mean ages were 68,68 years old in the right hip arthroplasty group, and 69,39 in the left hip arthroplasty group., Conclusions: A complex interaction between the development of lumbar disc herniations and increased contralateral cross-sectional area of the psoas muscle at the L4-5 level was observed in patients operated for unilateral hip arthroplasty. This interaction can be a compensatory mechanism to counteract the spinal imbalance.

Background: The aim of this study was to evaluate the effects of preoperative three-dimensional (3D) modeling on the performance of uniportal video-assisted thoracoscopic bronchial sleeve resection and early postoperative outcomes., Methods: A total of 10 patients (5 males, 5 females; mean age: 53.8±16.9 years; range, 18 to 75 years) who underwent uniportal video-assisted thoracoscopic bronchial sleeve resection with preoperative 3D modeling between April 2021 and November 2023 were retrospectively analyzed. Preoperative 3D modeling was prepared using computed tomography with an open-source 3D software program. Demographic, clinical, intraoperative, and postoperative data of the patients were recorded. Anatomical landmarks identified by preoperative 3D modeling were compared with intraoperative findings., Results: The anatomical landmarks created with the 3D model were in 100% agreement with the intraoperative findings. The procedures performed were three left lower lobes, three right upper lobes, one middle lobe, one right lower lobe, and one parenchyma-sparing intermediate bronchial sleeve resection. Bronchial sleeve resection was completed using uniportal video-assisted thoracoscopic technique in 90% of patients, with only one patient requiring conversion to open thoracotomy. The mean resection time was 264.2±40.5 min, and the mean anastomosis time was 86.0±20.3 min. Anastomosis times decreased with increasing experience (p=0.008). Postoperative atelectasis was observed in two patients, and there was no mortality. The mean follow-up duration was 12.2±11.8 months., Conclusion: Preoperative 3D modeling significantly contributed to the successful implementation of uniportal video-assisted thoracoscopic bronchial sleeve resection surgery. In the future, with advancements in simulation programs, patient-specific 3D modeling is expected to benefit the identification of anatomical landmarks for bronchial sleeve resections., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2024, Turkish Society of Cardiovascular Surgery.)

In patients with COVID-19, neurodegeneration may develop before clinical symptoms appear. Diffusion-weighted (DW) MRI is an important technique for analyzing microstructural changes such as gliosis. In this study, a quantitative evaluation of microstructural changes in the brain with apparent diffusion coefficient (ADC) values in patients presenting with a headache after the COVID-19 disease was analyzed and compared. DW MR images of patients of 20 COVID-19 patients (13 females, 7 males) who required imaging due to headache; 20 controls (16 females, 4 males) were retrospectively reevaluated. ADC measurements were taken from 16 regions of the brain, including right and left symmetrical in patients with COVID-19 infections and control groups. All regions of interest (ROIs) were taken from the hypothalamus, parahippocampus, thalamus, corpus striatum, cingulate gyrus, occipital gyrus, dentate nucleus, and medulla oblongata posterior. ADC values in the dentate nucleus right (784.6 ± 75.7 vs. 717.25 ± 50.75), dentate nucleus left (768.05 ± 69.76 vs. 711.40 ± 52.99), right thalamus (731.15 ± 38.14 vs. 701.60 ± 43.65), left thalamus (744.05 ± 39.00 vs. 702.85 ± 28.88), right parahippocampus (789.10 ± 56.35 vs. 754.75 ± 33.78), right corpus striatum (710.00 ± 39.81 vs. 681.55 ± 39.84) were significantly higher than those in the control group. No significant changes were observed in other areas. A significant increase in ADC values at many levels in the brain in patients with COVID-19 disease and headache was observed. Thus, this study indicates that cerebral involvement in COVID-19 disease may be related to microstructural changes that are not reflected in conventional MRI images., Competing Interests: None

Objective: Ponticulus posticus is an anomaly of the atlas. Odontoid fracture type 2 fracture occurs by hyperflexion, hyperextension, lateral flexion, and a combination of these movements. The presence of Ponticulus Posticus anomaly may affect the occurrence of odontoid fractures of the C2 vertebra. In this study, the relationship between the presence of PP anomaly and occurring of the odontoid type 2 fracture was investigated., Patients and Methods: Cervical CTs of a total of 14 patients with odontoid type 2 fracture were retrospectively evaluated for PP, and compared with 13 patients with cervical trauma without odontoid type 2 fracture., Results: Ponticulus posticus anomaly was noted in 7 of 14 patients with odontoid type 2 fractures on the upper cervical CT; therefore, the prevalence was 50.%, but only 3 cases (23.07%) were seen in 13 patients of the control group. In binominal regression analysis showed that the presence of PP anomaly increases 12,075 times to occur odontoid type 2 fracture after cervical trauma., Conclusion: Ponticulus posticus is often not recognized, but this study shows that ponticulus posticus is a risk factor for odontoid type 2 fracture after cervical trauma., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Ltd.

Aim: To determine the relationship between the occurrence of lumbar L4-5 disc herniation (LDH) and the size of psoas muscles., Material and Methods: The cross-sectional areas (CSAs) of the psoas muscles were measured at the L4-5 disc level on axial MRI of patients with LDH who were admitted to the hospital between 1 January 2020 and 1 June 2020. The patients were divided into three groups according to the involvement side of LDH as the patients without disc (Group I), right side disc (Group II), and left side disc (Group III). The relationship of ipsilateral and the opposite side of the CSA of PM in the control group and the patients with LDHs was analyzed., Results: This retrospective study included 65 patients (ages between 20 and 70 years) whose mean age is 42, 12. The mean values of the right side cross-sectional area of PM were 12.09 cm2 in Group I (n=18), 12.84 cm2 in Group II (n=20), and 14.15 cm2 in Group III (n=27), The left side values were 12.08 cm2, 13.22 cm2, 14.00 cm2 in Group I, II, and III, respectively. The difference between right and left side CSA of PM is that values of patients with left-sided LDHs were higher than those of the control and right-sided LDH group, and the difference was statistically significant. A strong correlation was observed between the left and right side of the cross-sectional area of psoas muscle at the L4-5 level (p < 0.05)., Conclusion: This study shows that there are reciprocal changes in the cross-sectional area of the psoas muscle in patients with L4-5 lumbar disc herniation.

In the medical literature, some case reports on the association of the COVID-19 infection and occurrence of spontaneous subarachnoid hemorrhage (SAH)have been reported Aim of the present paper is to search the causes of this association The diagnosis of COVID-19 was based on the real-time reverse-transcription polymerase chain reaction (PCR) test and computed tomography (CT) of the chest. There were four patients, whose median ages were 46,758, ranged 36-54 years). In conclusion, Spontaneous SAH can occur in the early and late course of COVID-19 infection. Its early recognition of the patient with spontaneous SAH is imperative., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Objective: To discriminate between malignant or benign axillary lymph nodes in breast cancer using MRI, PET-CT, and sentinel lymph node biopsy., Study Design: Observational study., Place and Duration of Study: Department of General Surgery, Recep Tayyip Erdogan University School of Medicine, from January 2014 to March 2019., Methodology: Sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) was carried out on 102 patients, who had locally advanced cases and had not previously received neoadjuvant therapy. Axillary lymph nodes pathology results were evaluated and compared with PET-CT and MRI findings., Results: PET-CT specificity was 93.18%, MRI specificity was 93.75%, and combined PET-CT and MRI specificity was 97.67%. PET-CT sensitivity was 81.03%, MRI sensitivity was 68.57%, and combined PET-CT and MRI sensitivity was 83.05%. For detecting the presence of axillary lymph node metastasis, there was a good correlation between histopathological results and the combined evaluation with PET-CT and MRI (kappa: 0.785, p <0.001). In combined PET-CT and MRI, short diamater mean values of lymph nodes in 10 patients, which could not detect lymph node metastases, were determined to be 5.2 ±0.9 mm., Conclusion: Combining PET-CT and MRI is superior to PET-CT or MRI imaging alone in distinguishing benign and malignant axillary lymph node; and contributes to deciding the approach to axillary lymph node surgery. Lymph node size is also important for this imaging method to determine benign and malignant nodes correctly. Key Words: Breast cancer, PET-CT, MRI, Sentinel lymph node biopsy, Axilla.

Aim: Controlled ovarian hyperstimulation results in elevated levels of estrogen during in vitro fertilization (IVF). Although serum ovarian steroid hormones were found to influence central nervous system and anesthetic requirements, the relationship between propofol requirements and serum estrogen concentration in women undergoing oocyte retrieval has not been studied. The aim of this study was to determine the relationship between serum estrogen and progesterone concentrations and the required propofol dose for loss of consciousness (LOC)., Methods: Ninety patients undergoing oocyte retrieval for IVF were enrolled. Anesthesia was induced by administration of 200 mL/h propofol (1%) infusion to reach LOC. Anesthesia was maintained with a propofol infusion guided by entropy. The correlation between estrogen, progesterone levels and propofol dose at the time of LOC was analyzed. Emergence time from anesthesia and total propofol consumption were recorded., Results: The mean serum estradiol concentration was 1825 ±1135 pg/mL. There was a significant positive correlation between serum estradiol and propofol dose required for LOC (Pearson's correlation r = 0.28, P = 0.008). Progesterone had no significant correlation with total propofol dose at the time of LOC. Patients with high estradiol levels (higher than the median value) had similar propofol requirement for LOC, total propofol consumption and emergence time with patients who had low (below the median value) levels., Conclusion: Although increased estrogen levels create a positive correlation with propofol dose for LOC, estrogen does not seem to be the only factor for anesthetic requirement of patients undergoing controlled ovarian hyperstimulation., (© 2018 Japan Society of Obstetrics and Gynecology.)

Objectives: The purpose of this prospective study was to evaluate the association between bilateral inguinal hernias and colorectal cancers., Purpose: Inguinal hernias are one of the most common subjects in surgical practice and have been known to be associated with some other pathologies since 1831. Although there are some series in literature reporting the association of colorectal cancers with inguinal hernias, it is still controversial to perform colorectal diagnostic tools in hernia patients. Colorectal cancers are particularly accused to be in association with synchronous bilateral hernias as they increase the intra-abdominal pressure., Methods: Rectosigmoidoscopy was performed in 110 consecutive bilateral hernia patients and the results were recorded prospectively. Patients having colorectal diseases were excluded., Results: There were no pathologies in 87 (%79,1) rectosigmoidoscopies, while benign pathologies (hemorrhoids, polyps and diverticulitis) were diagnosed in 23 (%20,9)., Conclusions: It has not been proved yet that colorectal cancers increase the incidence of bilateral inguinal hernias. The incidence of benign pathologies in our series was similar to that of same age population without hernia. As a conclusion of this study we believe that rectosigmoidoscopy is not necessary for synchronous bilateral hernias unless the patient has any complaints or risk factors. Colorectal screening tools are performed when the clinical findings or the story of the patient support colorectal cancers) (Tab. 1, Ref. 25).

Acinar cystic transformation of the pancreas is also known as acinar cell cystadenoma (ACC), and this is an extremely rare benign lesion that was first described in April 2002. We report here on a case of a previously asymptomatic patient with pancreatic ACC and this was diagnosed by computed tomography (CT) and magnetic resonance imaging (MRI). To the best of our knowledge, there is no previous report concerning the CT or MRI features of ACC in the medical literature. We present here the CT, MRI and pathological findings of pancreatic ACC.

Background and Aim: Umbilical hernia frequently accompanies cholelithiasis. It is possible to repair these hernias after completing cholecystectomy. We herein describe a simple modified technique for the repair., Patients and Method: The technique was applied to 10 patients undergone laparoscopic cholecystectomy. After cholecystectomy has been performed, periumbilical trocar incision is extended toward the umbilicus. The hernia sac is sent into the abdominal cavity and one or two simple sutures are put to approximate the fascial edges of the umbilical hernia. A similar approximation is done for trocar hole. A piece of polypropylene mesh covering both defects with an adequate overlap at four edges is fixed in onlay position., Results: No wound complications were recorded. After a median of 23 months (6-40 months) follow-up no recurrence was observed., Conclusion: This simple modified repair may especially be useful in centers where the surgeons can easily perform cholecystectomy laparoscopically, but are not familiar with laparoscopic hernia repair and mesh placement or haven't the equipment and material necessary for a laparoscopic repair.

Purpose: The aim of this study was to evaluate the efficacy of two absorbable film barriers, polylactic acid and sodium hyaluronate-carboxymethyl cellulose, in preventing postoperative intra-abdominal adhesions, inflammation, and fibrosis in an animal model., Methods: Forty Wistar albino rats were grouped as polylactic acid, sodium hyaluronate-carboxymethyl cellulose, and control. All rats underwent laparotomy with subsequent cecal wall abrasion and abdominal wall injury. The two treatment groups received polylactic acid or sodium hyaluronate-carboxymethyl cellulose film barriers, while control group received nothing. On postoperative day 21, three observers graded the intra-abdominal adhesions and resected specimens. Fibrosis, inflammation, and adhesions were graded using quantitative scoring systems., Results: When compared to control group, polylactic acid group showed significantly less inflammation and adhesion (p < 0.005), while there was no significant difference for fibrosis. Sodium hyaluronate-carboxymethyl cellulose group has showed significantly less adhesions (p < 0.005), but there were no significant differences among fibrosis and inflammation when compared to control group. There were no significant differences between polylactic acid and sodium hyaluronate-carboxymethyl cellulose groups on adhesion formation, inflammation, or fibrosis., Conclusions: Placement of polylactic acid or sodium hyaluronate-carboxymethyl cellulose film barriers between injured surfaces is associated with a significantly reduced rate of postoperative adhesions. No superiority was detected between two barriers.

Purpose: The aim of the present study was to evaluate the efficacy of an absorbable polylactic acid film barrier in preventing postoperative intra-abdominal adhesions, inflammation, and fibrosis in an animal model., Methods: Thirty Wistar albino rats were divided into treatment and control groups. All rats underwent laparotomy with subsequent cecal wall abrasion and abdominal wall injury. The treatment group had a polylactic acid film barrier placed between the cecal and abdominal injured surfaces while control group received nothing. The animals were sacrificed on postoperative day 21. Three observers graded the intra-abdominal adhesions and resected specimens for histological examination of fibrosis and inflammation. Fibrosis, inflammation, and adhesions were graded using a quantitative scoring system., Results: The treatment group showed significantly less adhesions and inflammation (P < 0.05), while there was no significant difference in the amount of fibrosis. Statistical correlations between adhesion-inflammation, adhesion-fibrosis, and inflammation-fibrosis were also significant (P < 0.05)., Conclusions: Placement of polylactic acid film barriers between injured surfaces is associated with a significantly reduced rate of postoperative adhesions and inflammation. This may be a promising result for reducing the morbidity and costs related to postoperative adhesions.

Background: The role of free oxygen radicals in inflammatory conditions is well known. Free radicals cause lipid peroxidation of cellular membranes resulting in cell death. The purpose of this study was to investigate the levels of total anti-oxidant status (TAS), as a marker of anti-oxidant defense system and malondialdehyde (MDA), as a marker of oxidative stress, in the plasma of patients with acute appendicitis., Methods: Fifty-one adult patients with a median age of 31 years who underwent operations with a preoperative diagnosis of acute appendicitis were included in this prospective study. Blood samples for C-reactive protein (CRP), MDA and TAS were collected preoperatively. Groups were compared by using the Mann-Whitney U test., Results: There were 27 patients with acute phlagmenous appendicitis and 19 patients with advanced appendicitis (10 gangrenous and 9 perforated appendicitis), while 5 negative explorations were documented. No significant differences in WBC counts and MDA levels between groups were encountered. Plasma CRP was significantly higher in patients with perforated appendicitis, but not in the other groups. In advanced appendicitis group, TAS level was significantly lower than the other groups. On the other hand, plasma TAS level in acute phlagmenous appendicitis group was significantly higher., Conclusion: A decrease in plasma total anti-oxidant capacity might be a predictor of the progression of inflammation to the perforation in acute appendicitis.

Background: Underlying hepatic injury and cirrhosis are leading factors that interfere with the post-operative liver regeneration and function. Hyperbaric oxygenation (HBO) has been reported to ameliorate the ischemia-reperfusion injury of the liver, to induce compensatory hypertrophy of the predicted remnant liver in rats after portal vein ligation and to augment liver regeneration after hepatectomy in non-cirrhotic rats. Our aim was to determine the effect of HBO treatment on liver regeneration after partial hepatectomy in normal and cirrhotic mice in this experimental study., Materials and Methods: The effect of HBO on liver regeneration was studied in a mice model combining carbon tetrachloride induced cirrhosis and partial hepatectomy. Mice were divided into four groups: Control, cirrhotic, non-cirrhotic HBO-treated, and cirrhotic HBO-treated. All animals underwent 40% hepatectomy. Liver regeneration was evaluated by the proliferating cell nuclear antigen-labeling index. Serum aspartate aminotransferase and alanine aminotransferase levels were measured to evaluate liver injury., Results: Serum alanine aminotransferase and aspartate aminotransferase levels were significantly decreased in HBO-treated cirrhotic group compared to cirrhosis group after hepatectomy (P = 0.001 and P = 0.014, respectively). The proliferating cell nuclear antigen labeling index was significantly higher in HBO treated cirrhotic group than in cirrhotic group after hepatectomy (P = 0.022)., Conclusions: Our results suggest that HBO treatment improves liver functions and augments hepatocyte regeneration in cirrhotic mice after hepatectomy. Post-operative HBO treatment may have a beneficial effect on post-operative liver function and regeneration in cirrhotic patients.

Background: Intrabiliary rupture is one of the most serious complications of liver hydatid cysts (LHC). The kind of surgery for these patients is still controversial. T-tube drainage and choledochoduodenostomy (CD) are used by most of the surgeons. But there is no comparative study in the literature., Methods: Eighty patients with symptomatic intrabiliary rupture were treated between 1980 and 1995. All patients had jaundice. In addition to treatment of the cyst cavity, T-tube drainage of the common bile duct (CBD) was performed in 53 patients, 25 patients underwent a CD for biliary drainage and two patients were treated by a T-tube placed in the CBD without treating the cyst. The T-tube drainage and CD groups were compared in regard to morbidity, mortality, duration of the operation, rate of relaparatomy and duration of postoperative hospital stay., Results: The morbidity rate was 40% (10/25) after CD and 18.1% (10/55) after T-tube drainage. Relaparatomy was necessary in 8% (2/25) and 1.8% (1/55) of patients treated with CD and T-tube drainage, respectively. T-tube drainage was performed much more rapidly than CD (p < 0.05). The length of hospital stay for both groups was the same. One patient who was treated with CD died postoperatively., Conclusion: Our results suggest that T-tube drainage is superior to CD for intrabiliary rupture of LHC in most cases., (Copyright 2001 S.

The reusability of disposable plastic trocars after high-level disinfection by alkalinized 2% glutaraldehyde solution was examined in a prospective study from the point of view of infection risk in order to determine the safety and economic benefits. For this purpose, 45 laparoscopic cholecystectomy cases were analyzed microbiologically and clinically. In 30 cases, trocars subjected to 15 min of disinfection by glutaraldehyde were used. In the remaining 15 cases, new trocars were used and a control group was established. In total, eight culture samples were taken from trocars, laparoscope (as it is disinfected by the same method), glutaraldehyde solution and umbilicus of the patients preoperatively; and from the bile in the gallbladder, peritoneal lavage fluid, and epigastric and umbilical incisions postoperatively. Only one of the disinfected trocars yielded a culture-positive result. No culture-positive results were found in the samples taken from laparoscope, glutaraldehyde, and epigastric incisions. Culture-positive results were obtained in 11 cases at the umbilicus, in one case at the peritoneal lavage and in one case at the umbilical incision. None of the patients had infection at the wound site or intra-abdominally. In conclusion, we have shown that disposable plastic trocars subjected to high-level disinfection can be reused safely without infection risk and that cost can be reduced.

This report details the perioperative management of 488 patients who underwent surgery for hydatid cysts of the liver. The most common pathology was a single cyst in the right lobe of the liver (53%). The preferred surgical procedures were partial cystectomy with closure of the residual cavity by suturing (31%) and total cystectomy (18%). Communication with the biliary system was found in 13% of cysts. The presence of multiple cysts and the need for additional procedures contributed to the overall perioperative morbidity (42%) and mortality (1%).
