OBJECTIVE The ongoing pandemic coronavirus disease-2019 (COVID-19) infection causes severe respiratory dysfunction and has become an emergent issue for worldwide healthcare. Since COVID-19 spreads through contact and droplet infection routes, careful attention to infection control and surgical management is important to prevent cross-contamination of patients and medical staff. Tracheostomy is an effective method to treat severe respiratory dysfunction with prolonged respiratory management and should be performed as a high-risk procedure METHOD The anesthetic and surgical considerations in this case involved difficult goals of the patient safety and the management of infection among health care workers. Our surgical procedure was developed based on the previous experiences of severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). RESULTS We described the management procedures for tracheostomy in a patient with COVID-19, including the anesthesia preparation, surgical procedures, required medical supplies (a N95 mask or powered air purifying respirator, goggles, face shield, cap, double gloves, and a water-resistant disposable gown), and appropriate consultation with an infection prevention team. CONCLUSION Appropriate contact, airborne precautions, and sufficient use of muscle relaxants are essential for performing tracheostomy in a patient with COVID-19. V.We compared copeptin levels in relapsing-remitting multiple sclerosis (RRMS) patients with controls and investigated how plasma copeptin levels were changed with the disease period. Thirty patients with RRMS without a prior attack in the last twelve months, and 19 RRMS patients with a clinical acute attack and 30 healthy individuals were included into the study. CP-456773 inhibitor Copeptin levels were significantly higher in all RRMS patient groups than healthy controls. Plasma copeptin levels were higher in patients in remission period compared with relapse period of 19 RRMS patients with an acute attack. We consider copeptin can be used as a potential biomarker for RRMS. STATEMENT OF PROBLEM Information on the morphological accuracy of crowns produced by different technologies is limited. PURPOSE The purpose of this in vitro study was to compare the morphology and contacts of crowns fabricated with intraoral systems, extraoral systems, and conventional method. MATERIAL AND METHODS A typodont mandibular first molar (Nissin Dental Product) received a complete ceramic crown preparation and a reference crown. Microcomputed tomography (μCT) was used to obtain the virtual data (REF) of the reference crown. Three groups of replicated crowns were made intraoral scanning system (TRIOS), extraoral scanning system (D700), and the conventional method (CONV) (n=8). The groups TRIOS and D700 were designed by the correlation method. All crowns were scanned with μCT to obtain 3D data. The data were superimposed on each other or the REF in an inspection software to evaluate precision and trueness. The contact penetration area of the occlusal surfaces of the crowns was calculated. An independent sample t test and 1-way ANOVA with the post hoc least significant difference (LSD) test were used to compare the data (α=.05). RESULTS The crowns fabricated with the extraoral scanners showed significantly lower root mean square (RMS) values for trueness (F=1456.90, df=2, P less then .001) and precision (F=188.88, df=2, P less then .001) than the others. link2 The penetration contact area ratio and the differences in the CONV group were both significantly higher than those of the other groups. CONCLUSIONS The average discrepancies of the crown morphology fabricated from the extraoral scanning were significantly lower than those from others. The conventional method restored the occlusal contact with significantly less accuracy than the other groups. This clinical report details the rehabilitation of a patient who underwent a total rhinectomy, subsequent adjuvant radiation therapy, and eventual prosthetic rehabilitation but then developed an empirically diagnosed medical adhesive intolerance. With the aid of digital planning and real time navigation, 2 zygomatic implants were placed by using a flapless surgical approach followed by early delivery of an interim prosthesis. In spite of the failure of 1 craniofacial implant, definitive restoration was accomplished by using a titanium bar, double magnetic attachments, and a new silicone prosthesis. STATEMENT OF PROBLEM Edentulism has been associated with sensoneurinal hearing reduction, but whether hearing is improved by the provision of an implant-retained overdenture is unclear. PURPOSE The purpose of this pilot clinical study was to provide completely edentulous participants with implant-retained complete overdentures and to evaluate the effect on their hearing ability by pure tone audiometry (PTA). MATERIAL AND METHODS Fifteen completely edentulous first-time denture wearers were enrolled, and their hearing was evaluated with PTA for air conduction and bone conduction at 6 time intervals before denture insertion (R1), after denture insertion (R2), 1 month after denture insertion (R3), on the day of suture removal after implant surgery (R4), 3 months later, at the time of loading (R5), and 1 month after implant loading (R6). The Friedman test was performed to find significant differences in the measurements from the completely edentulous state to rehabilitation with a complete denture and an implant-retained complete overdenture. The post hoc Tukey test was used for multiple comparisons (α=.05). RESULTS Significant differences were found between R1 and R6, between R2 and R6, between R3 and R6, and between R4 and R6 in PTA in multiple comparisons (P less then .05). The post hoc test revealed significant difference in the R1and R6 and R3 and R6 pairs (P less then .05) at 500 Hz, 1 kHz, and 8 kHz, whereas only between R1 and R6 (P less then .05) at 2 kHz for the air conduction test. In the bone conduction test, a significant difference was observed between the R1 and R6 and the R3 and R6 pairs (P less then .05) at 500 Hz and 4 kHz, but only between R3 and R6 (P less then .05) at 1 kHz and 2 kHz. CONCLUSIONS The study showed that the placement of dental implants improved hearing acuity via the acoustic pathway through air and bone conduction. To use the advantages of transarticular screw fixation while minimizing iatrogenic involved joint damage and screw irritation, it is important to determine the screw size. The aim of this study was to analyze the outcomes of percutaneous reduction and 2.7-mm cortical screw fixation for low-energy Lisfranc injuries and determine whether the procedure is a safe alternative to traditional screw fixation using a larger screw size. A review was performed for all patients who underwent percutaneous reduction and 2.7-mm cortical screw fixation for low-energy Lisfranc injuries at a single institution over a 6-year period. Thirty-one patients were enrolled in this study. Patients were assessed clinically and radiographically for demographics, foot function index (FFI), numerical rating scale (NRS) for pain, patient satisfaction, and complication rates. Factors affecting screw breakage and its clinical relevance were also analyzed. The FFI and NRS for pain were 17.2 ± 14.7 (range 0.8 to 57.8) and 3.1 ± 2.3 (range 0 to 8) points, respectively, at the 12-month follow-up visit. One patient (3.2%) underwent arthrodesis for the development of posttraumatic arthritis; all other patients recovered without sequelae. Screw breakage was identified in 7 patients (22.6%). There was no significant difference between patients with and without screw breakage in terms of FFI, NRS for pain, patient satisfaction, or complication rate. Body mass index (BMI) was significantly higher in patients with screw breakage than in those without screw breakage. Receiver operator characteristics curve analysis demonstrated a strong relationship between BMI and screw breakage (area under the curve = 90%, p less then .001), and the potential BMI cutoff value was 27.8 kg/m2. After considering the incidence of screw breakage, percutaneous reduction and 2.7-mm cortical screw fixation can be a viable option for treating low-energy Lisfranc injuries in nonobese patients, especially those with BMI less then 27.8 kg/m2. Dorsal dislocation of the interphalangeal joint of the great toe is quite rare. Closed reduction is often attempted in the emergency setting, but this measure is seldom successful because of invagination of the sesamoid-plantar plate complex into the interphalangeal space. Generally, open reduction is indicated when closed reduction fails. In this report, percutaneous reduction of the incarcerated sesamoid was performed under local and intraarticular anesthesia at our outpatient clinic, leading to successful reduction. Ankle fracture dislocations with frustrating attempts at closed reduction are a rare traumatic entity. We present a case of an irreducible ankle fracture due to incarceration of all the flexor tendons including the neurovascular bundle in the tibial fibular interosseous space; to date, only one such case has been published in the literature. A computed tomography scan in both bone and soft tissue windows was necessary to clarify the structures that were inhibiting repositioning. The decisive step for surgical treatment was removal of the trapped structures from the tibial fibular interosseous space by a dorsomedial approach. The malleolar joint was then reconstructed anatomically. After 12 weeks, the patient was fully mobile without restrictions in his daily professional activities. INTRODUCTION Cirrhosis of the liver is a serious public health problem worldwide, with regional variations determined by cultural factors and economic development. AIM To know the characteristics of the social, cultural, and economic factors of the patients with cirrhosis of the liver in Veracruz. MATERIALS AND METHODS A multicenter, retrolective, relational research study was conducted on patients with cirrhosis of the liver at five healthcare institutions in Veracruz. The variables analyzed were etiology, age, sex, civil status, educational level, occupation, and income. Descriptive and inferential statistics were utilized, and statistical significance was set at a P less then .05. The Windows IBM-SPSS version 25.0 program was employed. RESULTS A total of 182 case records of patients with cirrhosis of the liver were included. link3 The etiologic factors were chronic alcohol consumption (47.8%), viral disease (28.5%), nonalcoholic fatty liver disease (NAFLD) (8.79%), autoimmune liver disease (4.4%), cholestasis (1.64%), and cryptogenic liver disease (8.8%). Mean patient age was 66.14±13.91, with a predominance of men (58.79%). In comparing the socioeconomic and cultural factors related to etiology, secondary and tertiary education and singleness were statistically significant in male alcoholics (P less then .05), viral diseases and NAFLD were significantly associated with women with no income (P less then .05), cryptogenic liver disease was significantly associated with women (P less then .05), and cholestasis and autoimmune liver disease were not significantly associated with any of the factors. CONCLUSIONS The study results revealed the influence of socioeconomic and cultural factors related to the different causes of cirrhosis of the liver in our environment.
