Aim: The aim of this study is to compare the surgical accuracy and efficiency of endo-osseous implant placement using a conventional method and when placed using a custom surgical guide.
Materials And Methods: The study was carried out in a case control design on 20 patients aged between 15 years and 60 years. In the study group ( = 10) the implants were placed with the help of a surgical stent, while in the control group ( = 10) implants were placed in a conventional manner (without surgical stent) planned only with CBCT scan. The same surgeon placed the implants in both the groups.
Results: Each patient was considered in terms of the number of implants received. Each planned and actual implant was compared in terms of the 8 quantitative variables, which were used to observe and compare the accuracy of the surgical guides and conventionally placed implants. Data were analysed by a single blinded statistician using statistical software (Graphpad Prism (Version 5)). The Microsoft excel and Student T test for parametric data and Chi-square test for categorical data were used to observe significant differences between the 2 study groups. The nonparametric Chi-Square test revealed a statistically significant difference between surgical stent guided and conventional surgery in terms of buccal and lingual/palatal cortical plate to implant deviation, adjacent tooth to implant deviation, and mesiodistal angular deviation, whereas the differences between the marginal bone loss deviation, stability deviation, pain and swelling deviation, treatment time and number of sessions deviation, satisfaction deviation were not statistically significant.
Conclusion: From our study, we can conclude that guided surgery is essential for insertion of the implants regardless of the surgical technique. The success of the guided surgery depends on accuracy of the clinical and/or laboratorial steps of the virtual planning. Despite all the limitations and probability of errors encountered in our study, the guided surgery is superior in better positioning of implants.

Background And Purpose: Symptoms indistinguishable from behavioral-variant frontotemporal dementia (bvFTD) can develop in patients with spontaneous intracranial hypotension associated with severe brain sagging. An underlying spinal CSF leak can be identified in only a minority of these patients and the success rate of nondirected treatments, such as epidural blood patching and dural reduction surgery, is low. The disability associated with bvFTD sagging brain syndrome is high and, because of the importance of the venous system in the pathophysiology of CSF leaks in general, we have investigated the systemic venous circulation in those patients with recalcitrant symptoms.

We report the case of a woman in her early 30 s who was diagnosed with Robert's uterus. She had been experiencing progressive dysmenorrhea for a decade and sought treatment for infertility at our hospital. Preoperative ultrasound imaging resulted in a misdiagnosis of a complete uterine septum with an accompanying ovarian cyst.

The year 2024 was rich in developments in the field of hepatology, gastroenterology, and interventional endoscopy. New molecules have been developed for the treatment of metabolic steatohepatitis, primary biliary cirrhosis, and inflammatory bowel diseases. Technological progress now makes it possible to perform screening measurements for portal hypertension directly under echo-endoscopic guidance and to extend the use of intraluminal stents to surgically modified anatomies.

The increasing age of patients with end-stage renal disease raises the issue of hostile arterial access for transplantation, with technical difficulties associated with clamping and suturing the iliac artery. Some of these patients - who theoretically represent those who would benefit the most from transplantation in terms of mortality - are contraindicated because of anatomical and medical issues. In this context, a specific endovascular device called EndoPreKiT (Endovascular Preparation for Kidney Transplantation) has been designed, enabling arterial access for transplantation via a mini-invasive procedure.

BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) encompasses a group of disorders ranging from hyperplastic to malignant lymphoid proliferations in the post-transplant period owing to immunosuppression, often in the setting of EBV transformation. PTLD is a rare complication of immunosuppression that, like lymphomas, can have a variable presentation based on disease localization. We report a case of PTLD mass effect at the porta hepatis for the first time in the literature, resulting in hepatic artery stenosis (HAS) and common hepatic duct obstruction.
