Filter by:The goal of this observational study is to compare postoperative results between patients who had total hip arthroplasty (THA) with and without the use of a computer navigation program. The main questions this study aims to answer are: - Can using computer navigation produce better THA implant placement? - Can using computer navigation make surgery more efficient? Participant data collected include their postoperative x-rays and total operative time.
The purpose of the study is to see if there is a connection between a proximal humerus fracture dislocation direction and the likelihood of developing avascular necrosis. Utilizing a retrospective cohort from the last ten years we hope to bring consenting patients back for a single visit to have x-rays and complete patient reported outcome measures to assess for evidence of avascular necrosis.
1. Kienböck's disease refers to avascular necrosis of the lunate carpal bone, known as lunatomalacia. It was first recognized and described by Austrian radiologist Robert Kienböck's in 1910 2. The lunate is the central bone in the proximal row, and it articulates with the scaphoid, capitate, triquetrum, and occasionally the hamate. More proximally, the lunate is a component of the radiocarpal joint, and it also articulates with the ulna via the triangular fibrocartilage complex (TFCC) 3. The exact cause of Kienböck's is not known, though there are thought to be a number of factors predisposing a person to Kienböck's. Although there is no evidence that Kienböck's disease is inherited, it is possible that unidentified genetic factors could contribute to the development of the condition, It is multifactorial, related to the following variables:Ulnar negative variance (or ulna minus),Vascular supply to the lunate bone,Lunatemorphology,Radial inclination angle,multiple wrist trauma 4. Kienböck's disease is the second most common type of avascular necrosis of the carpal bones, preceded only by avascular necrosis of the scaphoid. The typically affected population is males aged 20-40 years 5. Patients usually present with unilateral pain over the dorsal aspect of the wrist, limited wrist motion, weakness, or a combination of the three. Wrist extension and axial loading exacerbate pain. Symptoms range from mild to debilitating. It is rarely bilateral, and trauma is often absent. Physical examination commonly reveals wrist swelling, tenderness over the expected location of the lunate, synovitis, and loss of grip strength 6. Kienböck's disease is a clinical and imaging diagnosis. Both radiography/computed tomography and magnetic resonance imaging (MRI) are highly specific. However, MRI is the most sensitive and detects radiographically occult cases
Mortality from severe acute pancreatitis reaches 42%. The prognosis of acute pancreatitis is associated with the development of acute inflammatory response syndrome (SIRS) and multiple organ failure (MOF). Due to the lack of etiological therapy, the treatment of acute pancreatitis is predominantly symptomatic. Severity and mortality are associated with early systemic inflammatory response syndrome (SIRS) and septic complications at a later stage of the disease. With regard to the pronounced inflammatory response ("cytokine storm") during the early phase of endogenous intoxication of acute pancreatitis, extracorporeal removal of cytokines is a promising therapeutic approach. This prospective study examines the effect of early extracorporeal sorption of cytokines using the Efferon CT device on the severity of clinical symptoms of endogenous intoxication in acute pancreatitis and aseptic pancreatic necrosis.
Endoscopic ultrasound guided drainage of WON with metal stent is the mainstay of WON management. But there are few complications related to BFMS , like bleeding due to vessel erosion, stent clogging , stent migration . This study is to assess, whether placing an anchoring DPS through the BFMS will decrease adverse events or not. There are only 2 retrospective studies till date ,comparing LAMS with coaxial stent vs LAMS alone. one study showed no significant decrease in adverse events , one study showed decrease in adverse events when DPS with LAMS . But there has been no prospective RCT to assess the utility of DPS to date
The goal of this clinical trial is to evaluate the effect of cold saline (2.5 degrees Celsius) irrigation on postoperative pain in patients who require root canal treatment in molar teeth because of dead dental pulp and infection around the apex of the root of the involved teeth. This cold saline irrigation will be done after standard irrigation of the canal using a 5.25% sodium hypochlorite solution. The main questions it aims to answer are: - Is there any difference in postoperative pain when final irrigation is performed using a cold saline solution compared to the irrigation using the saline solution at room temperature in patients who require dental root canal treatment of molar teeth? - Because of cold saline irrigation, what type of adverse event/s may result? Participants will be asked to fill out a questionnaire before the start of the root canal treatment and record the preoperative pain using the visual analog scale (VAS). Root canal treatment will be completed in one visit. The standard procedure of root canal treatment will be followed, including irrigation of the canal using 5.25% sodium hypochlorite. As a final irrigation, either cold saline solution or a normal saline solution at room temperature will be used. The participants will be asked to fill out another questionnaire and record the presence, duration, and intensity of postoperative pain, and if painkiller medicine was taken immediately after completion of root canal treatment and at 6 hours, 12 hours, 72 hours, and 1-week intervals. The researcher will compare the effect of the final irrigation of a cold saline solution with that of a normal saline solution at room temperature on postoperative pain.
The purpose of this research study is to measure rate of decline and pattern of tissue oxygenation using the device, ViOptix T.Ox. ViOptix probes will be secured to the arm and hand. The recording process on the ViOptix machine will begin and obtain baseline StO2 levels for 5 minutes. After 5 minutes, a blood pressure cuff will be inflated on one arm. This blood pressure cuff will be left inflated for 10-20 minutes. Every 2 minutes a pulse check or doppler exam will be performed at your wrist. Last, the cuff will be deflated and the you will be free to leave the study room.
Apical patency is a technique in which the apical portion of the canal is maintained free of soft tissue remnants and dentinal debris by recapitulation with a small #10k file through the apical foramen. The purpose of this study is to evaluate the association between apical patency and postoperative pain in teeth with asymptomatic necrotic pulp among patients attending the Peshawar Dental College and Hospital. This single center, double blinded prospective RCT study will be conducted in Peshawar Dental College and Hospital. The inclusion criteria will be mature maxillary and mandibular molars and premolars diagnosed with asymptomatic necrotic pulp and apical periodontitis among 18-60 aged male and female patients, whereas pregnant patients, individuals with previously accessed teeth, and those having positive history of analgesic use within past 3 days will be excluded from the study. A total of 60 patients, after an informed consent will be randomly allocated one of the two groups i.e., apical patency (AP)(n = 30) and the non-apical patency (NAP) (n = 30) in a ratio (1:1).After administering localanaesthesia, root canal preparation will be completed using ProTaper rotary instruments.A size 10 K-filewas carried 1 mm beyond the working length in the patency groupused as a patency file.Patients will be asked to mark their pain intensity on 0-10 scale (NRS)for 7 days. Data will be analyzed using ChiSquare test, Student t-test, Kolmogorov-Smirnov test.
Severe acute pancreatitis (SAP) is the most severe form of acute pancreatitis (AP) and Infection of pancreatic necrosis (IPN) have shown to be one of the decisive factors defining the severity of illness. Minimally invasive techniques including endoscopy, laparoscopy, retroperitoneal approaches, etc., have recently been widely used for debridement because the procedure can further reduces surgical stress and performed not require general anesthesia, thereby reducing complications. Studies have shown that endoscopic transgastric necrosectomy can significantly reduced the proinflammatory response, complications, and hospital stay. Despite these advantages, there are some limitations with this approach. First, transgastric necrosectomy should be performed as late (about 4 weeks) in the course of the disease as possible to allow necrosis to wrap, since early debridement may result in a higher patient fatality rate. However, patients with SAP are often in a severely ill state due to sepsis or MODS at an early stage, which causes them unable to adhere to necrotic tissue encapsulation by conservative treatment. Second, the ideal patient to select for this approach has necrosis confined in the vicinity of gastroduodenal location. Last, up to 27% of IPN patients require additional percutaneous catheter drainage (PCD) after undergoing endoscopic transluminal therapy. This may be explained by the fact that dissemination of necrosis, digestive enzymes and inflammatory mediators from the necrotic tissue lumen to other parts of the abdominal cavity during endoscopic procedures. Percutaneous catheter drainage (PCD) has always been the principal treatment measure for patients with AP at early stage (< 4 weeks) or those with collections or necrosis extending into deeper anatomical planes. Irrigation through peripancreatic drainage placed after open laparotomy has been the standard treatment for patients with AP who had undergone surgical necrosectomy. However, this proactive approach has not been widely used in the setting of PCD. To adequate drainage and removal of necrosis, an early percutaneous continuous irrigation assisted vacuum drainage in combination with subsequent endoscopic transgastric necrosectomy which has not been reported so far was applied in critically ill patients with SAP.
Recruited patients with immature permanent maxillary anterior teeth with non-vital pulp, and periapical radiolucency, age ranging from 8 to16 years old were randomly allocated into three groups (n=13): Group I, disinfected using the triple antibiotic paste, Group II, disinfection was done using diode laser, and Group III, were disinfected using the triple antibiotic paste, diode laser was used for biostimulation. All groups were evaluated for the increase in root length and thickness and decrease in apical diameter at baseline, 3, 6, 9, and 12 months after treatment
