Immunoglobulin G4-related disease (IgG4-RD) is a fibroinflammatory condition of unknown etiology. Although the salivary glands are currently considered among the most commonly affected among them, oral and maxillofacial surgeons are generally not familiar with the condition. Enlargement of the major salivary glands may be the first identifiable sign of IgG4-RD. A salivary gland biopsy along with IgG4 serum level assessment may help differentiate IgG4-related sialadenitis (IgG4-RS) from malignancies, infectious diseases, and obstructive conditions. Greater knowledge and higher levels of awareness of IgG4-RS may contribute to the expansion of differential diagnostic and treatment approaches. This case report describes a patient with bilateral submandibular salivary gland swelling who was diagnosed as having IgG4-RS on the basis of the histopathologic findings of a submandibular salivary gland biopsy and subsequent IgG4 levels.

Objectives: The purpose of our study is to retrospectively analyze and compare the patterns of maxillofacial-related injuries among rides of electric-powered bikes (E-bikes) and electric-powered scooters (E-scooters), the associated risk factors, and the required treatment. Materials and methods: The medical files of all riders presenting to the emergency department at the Tel Aviv Sourasky Medical Center between 2019 and 2020 with oral- and maxillofacial-related injuries due to E-bike and E-scooter accidents were reviewed. Results: A total of 320 riders sustained oral- and maxillofacial-related injuries due to trauma involving E-bikes and E-scooters during the study period. E-scooter riders were involved in 238 accidents (74.5%) while E-bike riders accounted for the remaining 82 accidents (27.5%). Eighty-four out of 320 riders (26.25%) were hospitalized and required surgical interventions. Most of the 232 riders (72.5%) who reported not wearing a protective helmet during the index accident were E-scooter riders. In addition, 39 riders (18.66%) were riding either of these electric-powered vehicles under the influence of alcohol. Conclusions: E-bike riders are more likely to sustain a maxillofacial fracture than E-scooter riders. Not wearing a protective helmet and riding under the influence of alcohol are major risk factors for maxillofacial injuries.

Breast cancer (BrCA) is one of the most commonly diagnosed cancers and is the leading cause of cancer deaths in women worldwide. This study aimed to examine the association between the dietary inflammatory index (DII®) and BrCA among Jordanian women. A total of 400 adult women were enrolled into this case–control study. Cases were 200 women recently diagnosed with BrCA selected from the two hospitals that provide cancer therapy in Jordan. They were matched on age, income, and marital status with 200 BrCA‐free controls. DII scores were calculated from dietary data that were collected in a face‐to‐face interview conducted between October 2016 and September 2017 using a validated food frequency questionnaire. Conditional logistic regression models were used to calculate odds ratios (ORs) and 95% CIs. The study results revealed no significant associations between DII scores in relation to the odds of developing BrCA after multivariable adjustment including age, education, total energy, BMI, number of pregnancy, contraceptive use, lactation, smoking, and family history of BrCA. Stratified analyses by obesity status showed that overweight/obese participants in the highest DII tertile had a >75% increased BrCA risk (OR of 1.77 [95% CI, 1.01–3.12]) compared with participants in the lowest tertile, after adjusting for age. The results from this study showed no significant relationship between the proinflammatory potential of the diet and BrCA risk in the overall study population. However, results stratified by weight category indicated an effect of diet‐associated inflammation on BrCA risk in the overweight/obese group. Results of the study are consistent with a recommendation aimed at maintaining higher diet quality, that is, adopting healthy diets characterized by low DII scores in order to reduce the risk for BrCA.

This study aimed at exploring the effect of leadership styles on improving communication methods in Saudi universities from the perspective of faculty members. Four-hundred questionnaires were distributed to faculty members in the Saudi universities, 313 questionnaires were valid for analysis. The results showed that the most common leadership style among academic administrators in Saudi universities is the democratic style, followed by the laissez-faire leadership style, while the autocratic leadership style came in the third and last rank. Also, the results showed that one of the most common methods of communication is non-verbal communication related to symbols, movements, and expressions. in addition, the results revealed a significant effect was found positive of democratic leadership style on a communication method and a negative significant effect was found of autocratic leadership style and laissez-faire leadership style on communication method. Keywords: Leadership style, Communication method, Faculty Members, Academic Administrators

Background and objectives: This retrospective cohort study aimed to compare three postoperative antibiotic protocols of different durations on surgical-site-infection (SSI) rates following orthognathic surgery for the correction of jaw deformities. Materials and methods: An analysis on data collected from the medical files of 209 patients who underwent orthognathic surgery between 2010 and 2019 was conducted. The patients were divided into three groups according to the postoperative antibiotic protocol—Group 1 (24 h), Group 2 (2–3 days), and Group 3 (>3 days). Dependent and independent variables were collected, analyzed, and compared between the three groups. Results: Group 1 included 30 patients (14.3%), Group 2 included 123 patients (58.9%), and Group 3 included 56 patients (26.8%). The vast majority of the postoperative antibiotics were amoxicillinand clavulanic acid (87.1%). The duration of the surgery and the use of a feeding tube were significantly different between Groups 1 and 3 (p < 0.001 and p = 0.005, respectively). There was no significant difference in SSI rates between the three groups (p = 0.642). The use of antibiotics beyond the immediate postoperative period provides no increased benefit regarding infection prevention. Conclusions: In young and healthy patients undergoing orthognathic surgery, a 24hregimen of postoperative antibiotics may be sufficient.

The purpose of this study is to evaluate mandibular osteotomy procedures during orthognathic surgery, with an emphasis on the complications of the two leading procedures: intraoral vertical ramus osteotomy (IVRO) and sagittal split osteotomy (SSO). We conducted a retrospective cohort study by extracting the records of patients who underwent either IVRO or SSO procedures during orthognathic surgery in a single center between January 2010 and December 2019. A total of 144 patients were included (median age of 20.5 years, 52 males). The IVRO:SSO ratio was 118:26 procedures. When referring to all surgeries performed, IVRO procedures were associated with shorter hospitalization than the SSO procedures, while the overall durations of surgery and follow-up periods were comparable. In contrast, when referring only to bimaxillary procedures, the duration of the IVRO bimaxillary procedures was significantly shorter than the SSO bimaxillary procedures. There were 53 complications altogether. Postoperative complications consisting of skeletal relapse, temporomandibular joint dysfunction, sensory impairment, and surgical-site infection were significantly fewer in the IVRO group. Both types of osteotomies have acceptable rates of complications. IVRO appears to be a safer, simpler, though less acceptable procedure in terms of patient compliance.

The retrospective cohort study aimed to assess the incidence and characteristics of these complications in patients who underwent orthognathic procedures. Data on the intraoperative and the postoperative complications were extracted from the patients’ medical files. Procedures were further subdivided into single-jaw procedures and bimaxillary procedures. A total of 209 orthognathic procedures were carried out in 190 patients. 184 (88%) were performed to treat angle class III malocclusion, while 25 (12%) aimed to treat class II malocclusion. A total of 94 complication events were observed (44.9% of 209 procedures). 22 of them occurred in single-jaw procedures (28.2% of 78 single jaw operations), and 72 occurred in bimaxillary procedures (55% of 131 bimaxillary operations). When compared regarding the type of complication, complication rates were comparable between the study groups with the exception of late-stage malocclusion. A significant difference (p-value = 0.028) in malocclusion incidences between the bimaxillary and single-jaw groups were observed (9 events, 4.3% and zero events, 0%, respectively). The majority of the complications during and following orthognathic surgical procedures are temporary or minor and require little or no treatment at all.
