Crohn’s disease is a chronic inflammatory disease of the digestive tract with extraintestinal manifestations, which include skin conditions, arthritis, ocular inflammation, and several autoimmune conditions. Dermatologic manifestations in Crohn’s disease complicate the treatment course and prognosis and should be addressed promptly. Here, we report a 20-year-old male with a history of Crohn’s disease, presenting with palpable purpura, consistent with Henoch-Schönlein purpura, upon administration of ustekinumab. The immunoglobulin A vasculitis was treated with prednisone and the discontinuation of ustekinumab. Due to the increased usage of biological agents in inflammatory bowel diseases, associations between biologics and vasculitides should be further studied in Crohn’s disease patients for alternative treatment strategies and to understand potential adverse effects caused by biologics in Crohn’s disease.

PURPOSE: . This study aims to evaluate how the fit between implant-abutment connection surfaces and the proximal contact tightness of crowns affect abutment screw loosening. MATERIALS AND METHODS: . Forty implants with internal hex connections were placed in stainless steel models in the maxillary right first molar region. Monolithic zirconia crowns with standard and 15 µm reduced proximal contacts were used with abutments with standard and 25µm horizontally reduced hex connections. After cementation, four groups of specimens—standard abutment/standard proximal contact (control), reduced fit abutment/standard proximal contact (RS), standard abutment/reduced proximal contact (SR), and reduced fit abutment/reduced proximal contact (RR)—were subjected to simultaneous thermocycling (± 5 ‒ 55°C) and chewing cycles (100N, 1.6 Hz, 40 mm/sec lateral and vertical speed, lateral movement: 6 mm, vertical movement: 0.5 mm). Removal torque values (RTVs) were measured using a digital torque meter. Data were analyzed using two-way ANOVA and the Bonferroni test (α = .05). RESULTS: . All groups exhibited statistically significant differences compared to each other and the control group (P < .05). The RR group had the lowest removal torque values (RTVs) (21.70 ± 0.99 N·cm), while the control group had the highest (26.82 ± 0.70 N·cm). The RS group (24.78 ± 0.89 N·cm) had lower RTVs than the SR group (25.51 ± 0.52 N·cm). CONCLUSION . The findings indicate that inadequate proximal contacts and horizontal misfit of the implant-abutment connection may lead to torque loss and screw loosening.

Purpose: This study aimed to examine the therapeutic effects of injection of conditioned medium of adipose-derived mesenchymal stem cells (ADMSC-CM) in a surgically created varicocele model in comparison with varicocelectomy. Materials and Methods: Twenty-eight male Wistar Albino rats were randomly divided into four groups: sham group, varicocele group, varicocelectomy group, and ADMSC-CM injection group. Sperm parameters were analyzed in samples taken from the epididymis after treatment. Malondialdehyde and superoxide dismutase (SOD) levels in blood samples were examined by biochemical analysis. The testicular tissues were stained with hematoxylin-eosin for histological examination (Johnsen’s Score). Additionally, Western Blot analyzes were performed to detect Claudin-11 levels, the functional protein of the blood-testis barrier, in testicular tissues. Results: Varicocelectomy and ADMSC-CM treatments significantly improved mean sperm parameters (concentration, progressive motility, motility, normal sperm morphology) (p≤0.05 for all). Both treatment groups had increased SOD levels along with a decrease in malondialdehyde levels (p≤0.05 for all). No significant difference was observed between the ADMSC-CM group and the varicocelectomy group in preserving normal testicular histology according to Johnsen’s Score (p=0.114). Levels of Claudin-11 were significantly higher in the varicocelectomy and ADMSC-CM groups compared to the varicocele group (p≤0.05 for all). Conclusions The therapeutic effects of ADMSC-CM in varicocele model may involve secretion of anti-inflammatory and regenerative factors from ADMSC. ADMSC-CM injection appears to be a promising new strategy in the treatment of varicocele.

Endometrial cancer (EC) is the most common gynecological malignancy in developed countries, and endometrial intraepithelial neoplasia (EIN) is the defined precancerous lesion.Obesity is considered a risk factor for both EC and EIN. On the other hand, mortality is often attributed to obesity-related conditions in patients with early-stage EC. Bariatric surgery has been shown to improve oncological outcomes and obesity-related morbidity and mortality in patients with EC. Therefore, combination surgery addressing both uterine disease and obesity is a very recent point of interest. Here, we present a video article to demonstrate the crucial surgical steps for a simultaneous robotic-assisted total laparoscopic hysterectomy and sleeve gastrectomy in a patient with super obesity and EIN. A patient in her 40s with a body mass index of 62.4 kg/m 2 and a diagnosis of EIN was scheduled for combo surgery.The operation started with sleeve gastrectomy in the reverse Trendelenburg position. The da Vinci Xi Surgical System™ (Intuitive Surgical Inc., Sunnyvale, CA, USA) with left-side docking was used for surgery. After the mobilization of the stomach, gastric resection was performed using a stapler. Following sleeve gastrectomy, the patient was positioned in the Trendelenburg position, and the robotic system was positioned for hysterectomy.Hysterectomy and salpingectomy were performed. The excised stomach and hysterectomy material were removed through the vagina. A frozen examination revealed EC below 2 cm with superficial invasion, and bilateral oophorectomy was performed. The whole surgery took approximately 4 hours. No postoperative complications occurred, and the patient was discharged on the 3rd day.

Purpose: Deep vein thrombosis (DVT) contributes significantly to the mortality and morbidity of patients with and without cancer. Non-vitamin K antagonist oral anticoagulants (NOACs) and endovascular interventions have been included in the guidelines for special populations, such as those with cancer-associated DVT. This study aimed to evaluate the long-term outcomes of pharmacomechanical thrombectomy (PMT) compared to NOAC therapy in patients with iliofemoral DVT, and to perform an exploratory subgroup analysis of cancer-associated cases. Methods: This study included 126 patients who received only medical therapy (n = 66) and PMT (n = 60) for iliofemoral DVT. Of the patients who underwent PMT, 13 had cancer-associated DVT; 10 of them were in the NOAC group. All patients included in this study were retrospectively analyzed after 6 months and 1 year. The Villalta scale was used to measure the severity of post-thrombotic syndrome. Results: Villalta scores 1 year after DVT onset showed a strong positive correlation with those 6 months after DVT onset (ρ= 0.803, P < 0.001). Cancer-associated DVT patients (n = 13) who underwent PMT showed superior 1-year Villalta scores than did cancer patients (n = 10) who received NOAC treatment (Villalta score,12 vs. 8). This difference was similar to that observed in the non–cancer-associated population who underwent PMT (Villalta score,11 vs. 8). Conclusion Acute proximal DVT, regardless of malignancy induction, can be treated with endovascular interventions along with medical therapies. The evolution and development of endovascular treatments for DVT can improve the declining quality of life among patients with cancer-associated DVT.

Background/Aims: Dilated intercellular spaces (DISs) facilitate the diffusion of noxious agents into the deep layers of the esophageal epithelium. The role of DIS in heartburn pathogenesis is still controversial. Therefore, we aim to reinvestigate DIS in an extensively evaluated group of patients and healthy controls (HCs). Methods: We classified 149 subjects into the following groups: 15 HC, 58 mild erosive reflux disease (ERD), 17 severe ERD, 25 nonerosive reflux disease (NERD), 15 reflux hypersensitivity (RH), and 19 functional heartburn (FH). A total of 100 length measurements were performed for each patient’s biopsy. Results: The overall intercellular spaces (ISs) value of gastroesophageal reflux disease (GERD) patients was higher than that of HC (P = 0.020).In phenotypes, mild ERD (vs HC [P = 0.036], NERD [P = 0.004], RH [P = 0.014]) and severe ERD (vs HC [P = 0.002], NERD [P < 0.001], RH [P = 0.001], FH [P = 0.004]) showed significantly higher IS. There was no significant difference between the HC, NERD, RH, and FH groups. The 1.12 μm DIS cutoff value had 63.5% sensitivity and 66.7% specificity in the diagnosis of GERD. There was a weak correlation (r = 0.302) between the IS value and acid exposure time, and a weak correlation (r = −0.359) between the IS value and baseline impedance. A strong correlation was shown between acid exposure time and baseline impedance (r = −0.783). Conclusions Since the IS length measurement had better discrimination power only in erosive groups, it is not feasible to use in daily routine to discriminate other nonerosive phenotypes and FH. The role of DIS in heartburn in nonerosive patients should be reconsidered.
