Does a MediDiet With Additional Extra Virgin Olive Oil and Pistachios Reduce the Incidence of Gestational Diabetes?

OBJECTIVE: The present study aimed to evaluate gestational diabetes mellitus (GDM) incidence in pregnant women following the Mediterranean diet (MedDiet) with the addition of extra virgin olive oil (EVOO) and pistachios. METHODS: A total of 560 pregnant patients were enrolled in the present study. The MedDiet was introduced in both the interventional group (IG) and the control group. The women in the IG received 40 mL of EVOO every day along with 25 to 30 g of roasted pistachios. The incidence of GDM was recorded along with specific maternal and neonatal outcomes. RESULTS: The nutritional scores and MedDiet adherence screener scores were not statistically different between the groups at baseline, but the difference was statistically significant and higher in the IG at 24 to 28 weeks (P = .001) and at 36 to 38 weeks (P = .001). GDM was diagnosed in 51 (20.4%) women in the control group and 34 (13.6%) women in the IG. The MedDiet significantly reduced GDM incidence (P = .02) after adjusting for confounding factors. CONCLUSION: The present study shows that dietary intervention in pregnant women, including a MedDiet and increased consumption of EVOO and pistachios, decreases the incidence of GDM.

Is skip metastases associated with tumor thickness and tumor size in tongue carcinoma patients?

OBJECTIVE: To assess the correlation of skip metastases associated with increase in tumor thickness and size of the tumor. MATERIAL AND METHODS: A retrospective analysis was carried out from August 2009 to August 2015. In this study, a total number of 33 carcinoma tongue patients having T1, T2, and T3 sizes with N0 and N+ clinical necks who were treated by supraomohyoid neck dissection, extended supraomohyoid neck dissection, and modified radical neck dissection were analyzed. The data was assessed using Shapiro-Wilk W test, Nagelkerke R2 regression model, mean, and standard deviation. RESULTS: Metastasis to lymph nodes was present in 75% of patients. Level I and level II were the commonest sites to be involved, i.e., 20 patients. Three patients had skip metastasis out of which two patients had metastasis at level III (6%), and one patient had skip metastasis at level IV (3%). CONCLUSION: The incidence of skip metastasis increases with tumor thickness and tumor size in tongue carcinoma patients. CLINICAL RELEVANCE: The article reveals the positive relationship between tumor thickness, tumor size, and skip metastasis. The analysis shows tumor thickness as a higher predictor for skip metastasis with odds ratio of 5.5 compared to the tumor size having odd ratio 2.

Is Superselective Neck Dissection Safer Than Supraomohyoid Neck Dissection for Oral Carcinoma Patients With N0 Neck in Terms of Shoulder Morbidity and Recurrence Rate?

PURPOSE: To estimate the clinical and functional results of patients who underwent distinctive types of neck dissection, with particular emphasis on shoulder function, rate of recurrence, and quality of life in patients with N0 neck. MATERIALS AND METHODS: A randomized clinical trial was conducted from August 2014 to March 2017 in which 20 adult patients with T1 to T3 lesions of the oral cavity and N0 neck were included. Patients were randomly allocated to group I (n = 10; selective neck dissection) or group II (n = 10; superselective neck dissection). All patients were evaluated objectively for degree of arm abduction and subjectively for quality of life using a questionnaire completed pre- and postoperatively at 6 months. Also, locoregional recurrence was investigated for 2.5 years. Data were scrutinized by applying mean and standard deviation, unpaired t test, Mann-Whitney U test, and Kaplan-Meier test. RESULTS: Mean values of the Arm Abduction Test and quality-of-life scores were statistically significant (P < .05) for group II compared with group I at all intervals. Data analyzed for locoregional recurrence showed a statistically significant difference between groups (P < .05), with group II having the better outcome. CONCLUSION: The results showed less shoulder morbidity and improved quality of life for superselective neck dissection (group II) compared with selective neck dissection (group I). Furthermore, group II was better for locoregional recurrence, which determines the oncologic safety of the procedure.

Role of emergency chest ultrasound in traumatic pneumothorax. An updated meta-analysis.

AIM: To assess chest ultrasound (US) diagnostic accuracy in pneumothorax diagnosing. MATERIAL AND METHODS: Prospec-tive studies related to the US pneumothorax diagnostic accuracy in trauma patients were extensively searched from 2000 up to November 2020. The studies features and findings were gathered using a standardised form and the methodological quality of the investigations was evaluated using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). RESULTS: Twelve articles were finally chosen for quantitative analysis. The overall sensitivity of US scan in pneumothorax diagnosis was 89% (95%CI 86-91%). Specificity was 96% (95%CI 95-97%). The diagnostic odds ratio was 193.94 (59.009-637.40) at 95%CI, thus demonstrating high chest US accuracy in pneumothorax diagnosis. CONCLUSION: Despite the limitations of the included studies, this systematic review and meta-analysis concluded that chest US is a reliable method for diagnosing pneu-mothorax in traumatized patients.

Effectiveness of zinc supplementation on the incidence of oral mucositis during chemotherapy and radiation: A meta­analysis.

Oral mucositis (OM) is a commonly observed and debilitating side effect of chemotherapy and radiation therapy in patients with cancer, especially head and neck cancer. Although there is no proven therapy for the prevention and treatment of OM, zinc supplementation effectively decreases the incidence of OM. This paper provides a current and comprehensive meta-analysis of the efficacy of zinc compared with placebo/control in OM. A systematic literature review was conducted using MEDLINE and Central databases for randomized control trials (RCTs) comparing zinc supplementation (oral or rinse) with placebo/control in patients with various types of cancer undergoing chemotherapy, radiation therapy or combined chemo-radiation. The outcome was OM incidence, independent of the severity. A random-effects model was used to calculate the pooled risk ratio and subgroup analyses were performed. A total of 12 RCTs were included, containing information from 783 patients. A decrease in OM incidence was observed overall when all cancer therapies were considered. However, subgroup analyses showed that zinc did not significantly decrease the incidence of OM when studies were stratified by cancer therapy or scale/criteria used to assess OM. The results of the meta-analysis support the use of zinc supplementation in decreasing OM incidence in patients with cancer receiving chemotherapy or radiation therapy. However, the high heterogeneity between studies and the small number of studies are limitations of the meta-analysis.

Evaluating the influence of health literacy and health-promoting COVID-19 protective behaviors on the spread of infection during the COVID-19 pandemic: A meta-analysis.

BACKGROUND: Health literacy and self-efficacy related to COVID-19 pandemic management are closely linked. Therefore, synthesis of relevant evidence regarding the positive aspects of health literacy and health-promoting protective measures among individuals during COVID-19 pandemic is necessary. OBJECTIVES: To determine the influence of e-health literacy and health-promoting coronavirus disease 2019 (COVID-19) protective behaviors on the spread of infection during the COVID-19 pandemic. MATERIAL AND METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, PubMed, MEDLINE, PsycINFO, EMBASE, and Cochrane Library databases, as well as PROSPERO and ClinicalTrials.gov registry platforms were searched for eligible literature published from January 2020 to July 2022. Studies were included based on predefined Population, Intervention, Comparison, Outcomes and Study design (PICOS) criteria, and a summary of each study was prepared. To estimate the effect size, the standardized mean difference (SMD) of the evaluated parameters, e-health literacy and health-promoting COVID-19 protective behaviors was extracted. Using RevMan and MedCalc software, a meta-analysis was performed. RESULTS: Twelve eligible studies involving a total of 9854 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected individuals were included in the meta-analysis. The pooled SMD for e-health literacy was 40.39 (95% confidence interval (95% CI): 28.14-52.63), with the following heterogeneity values: Tau2 of 396.80, ÷2 of 669.48, degrees of freedom (df) of 11, I2 of 98%, Z value of 6.47, and p < 0.001. Similarly, the pooled SM for COVID-19 protective behaviors was 15.90 (95% CI: 10.96-20.84) with Tau2 of 55.25, ÷2 of 252.92, df of 11, I2 of 98%, Z of 6.31, and p < 0.001. CONCLUSION: This study confirmed that e-health literacy and health-promoting COVID-19 protective behaviors have a strong positive impact on preventing the spread of COVID-19 infection and on its effective management. We recommend that interventions and applicable policies for promoting such e-literacy programs and preventative measures be given a high level of consideration.

Does pedicle flap design influence the postoperative sequel of lower third molar surgery and quality of life?

Objective: To determine the impact of the buccal envelope flap and pedicle design on the post-operative outcome and quality of life following lower third molar surgery (QoL). Materials and methods: A randomized case-control clinical study was carried out from September 2017 to September 2019. In this study, a total number of 50 patients with mandibular third molar impaction underwent surgical removal of the same using buccal envelope flap (group A) and pedicle flap (group B). The patients were assessed postoperatively for pain, swelling, trismus, wound dehiscence, dry socket, and quality of life for one month. Results: In terms of pain, swelling, and trismus, there was no statistical difference between the two groups (p > 0.05). However, there was a statistically significant difference found in group B (pedicle flap) in terms of wound dehiscence, dry socket, and quality of life (p < 0.05). Conclusion: The pedicle flap demonstrates fewer incidences of wound dehiscence, dry socket, and a better quality of life when compared to the envelope flap.

Does povidone-iodine application in surgical procedures help in the prevention of surgical site infections? An updated meta-analysis.

Introduction: Surgical site infections (SSIs) occur after an operative procedure and can range from superficial to deep wound infections. The World Health Organization (WHO) and the Centers for Disease Control (CDC) have proposed guidelines recommending measures to prevent SSIs. Intraoperative measures are largely focused on decontamination of the skin and intraoperative wound irrigation using soap and antiseptics and are simple, efficient, and cost-effective measures to reduce SSIs. Povidone-iodine (PVI) is a topical antiseptic widely used for the reduction of SSIs. Aim: A meta-analysis was conducted to determine the efficacy of preoperative or intraoperative use of PVI from randomized controlled trials (RCTs). Material and methods: A systematic literature review was conducted using MEDLINE and Central databases for RCTs that involved PVI application versus saline or no treatment control groups across various surgical categories. The primary outcome was SSI or post-operative wound infections. A random-effects model was used to calculate the pooled risk ratio and subgroup analyses were performed. Results: A total of 59 RCTs were included in the meta-analysis with information from 20,497 patients. A reduction in overall SSI incidence was found (RR = 0.70, 0.60-0.80, p = 0.0002, I2 = 44%). Subgroup analyses showed that the comparator treatment and type of procedure did not modify the effect of PVI on SSI incidence. However, inconsistent results on SSI incidence were obtained when the data were stratified by PVI application method and surgery category. Conclusions: The results of the meta-analysis provide support for the preoperative or intraoperative use of PVI in decreasing the incidence of SSI.

Does initial reduction at infra-orbital rim first improve malar height and vertical dystopia in ZMC fractures?

PURPOSE: To estimate the clinical and functional results of patients who underwent distinctive types of open reduction and internal fixation of ZMC fractures, with particular emphasis on malar height and vertical dystopia. MATERIALS AND METHODS: A randomized clinical trial was conducted from August 2016 to October 2019 in which 40 adult patients with ZMC fractures of maxillofacial region were included. Patients were randomly allocated to group A (n = 20; frontozygomatic (F-Z) first 3-point reduction and fixation) or group B (n = 20; group B infra-orbital first 3-point reduction and fixation). All patients were evaluated objectively for malar height and vertical dystopia pre- and post-operatively at 3 months. The data were scrutinized by applying mean and standard deviation and unpaired t test. RESULTS: Mean values of the malar height and vertical dystopia were statistically significant (P < .05) for group B compared with group A at all intervals. Data analyzed for other secondary variables showed a statistically non-significant difference between the groups (P > 0.05). CONCLUSION: The results showed improvement in the malar height and vertical dystopia for infra-orbital first three-point fixation (group B) compared with F-Z first approach for initial reduction and fixation (group A). Furthermore, group B was better in terms of malar width and antero-posterior projection of the zygomaticomaxillary complex.

Use of Transgingival Lag Screw Osteosynthesis in the Management of Alveolar Process Fracture.

The purpose of this study is to check the efficacy of transgingival lag screw osteosynthesis in alveolar process fractures of maxilla and mandible. A single-arm nonrandomized observational study was performed for the treatment of alveolar process fractures of maxilla and mandible. In this study, 20 mixed age group patients with alveolar process fracture were included. All the patients were treated by a 2.0-mm transgingival screw fixation under local or general anesthesia. All the patients were evaluated for fracture stability, anatomical reduction, bone loss and bone resorption of alveolar process, tooth loss, and wound infection at 3 months of follow-up. A simple descriptive statistical analysis was done to evaluate the parameters and it was shown that the treatment of alveolar process fracture with two or three lag screws provides adequate fracture stability and anatomical reduction with no signs of bone loss and tooth loss, and wound infections were noted post lag screw fixation. The study concludes that transgingival lag screw fixation is a suitable alternative for alveolar process fractures in all the age groups and two to three lag screws are generally sufficient to fix fractured alveolar process either under local anesthesia or general anesthesia.

Retraction: Is treatment with platelet-rich fibrin better than zinc oxide eugenol in cases of established dry socket for controlling pain, reducing inflammation, and improving wound healing?

[This retracts the article on p. 76 in vol. 45, PMID: 31106135.].

Is treatment with platelet-rich fibrin better than zinc oxide eugenol in cases of established dry socket for controlling pain, reducing inflammation, and improving wound healing?

OBJECTIVES: To appraise the effectiveness of platelet-rich fibrin (PRF) in the management of established dry socket in terms of pain, inflammation, and wound healing. MATERIALS AND METHODS: Two hundred patients with established alveolar osteitis were studied to determine the efficacy of PRF and zinc oxide eugenol (ZOE) for pain control, inflammation reduction, and wound healing. Patients were randomly allocated to Group A (PRF) or Group B (ZOE). Patients were examined on the 1st, 3rd, 7th, and 14th postoperative day and evaluated for pain using visual analogue scale scores, inflammation with a gingival index score, and wound healing through a determination of the number of bony walls exposed. RESULTS: Group A showed better results in terms of pain remission, control of inflammation, and wound healing compared to Group B. Results between groups were statistically significant (P<0.05). CONCLUSION: PRF is a better alternative than ZOE for the effective management of alveolar osteitis.

Versatility of platelet rich fibrin in the management of alveolar osteitis-A clinical and prospective study.

OBJECTIVE: To assess the efficacy of Platelet Rich Fibrin (PRF) on the pain and healing of the extraction socket associated with Alveolar Osteitis (Dry Socket, AO) after removal of maxillary and mandibular molars. STUDY DESIGN: 100 adult patients with age group ranging from 18 to 40 years along with established dry socket after maxillary and mandibular molar extractions who have not received any treatment for the same were included in the study. PRF was placed in the maxillary and mandibular molar extraction sockets after adequate irrigation of the socket. All the patients evaluated for the various study variables which include pain, degree of inflammation, and healthy granulation tissue formation at 1st, 3rd, 7th, and 14th post operative day. Data were analyzed using Shapirowilk's test, chi square test and/or student-t test, Friedman's test, Wilcoxson's signed rank test, and Bonferroni test, with the significance level set at P < 0.05. RESULTS: There was significant reduction in pain associated with AO at the 3rd and 7th postoperative day along with better wound healing by the end of 2nd week. CONCLUSION: Use of PRF in this study illustrates the promising results in terms of reduced pain and better healing in the patients with Alveolar Osteitits.

Is a deep subfascial approach better than the subfascial apporach to temporo-mandibular joint in terms of facial nerve injury and quality of life?

PURPOSE: The objective of the study was to compare the deep subfascial approach to subfascial approach in terms of facial nerve injury and quality of life. MATERIALS AND METHODS: A randomized study was performed from August 2013 to March 2017 on 24 patients with unilateral TMJ ankylosis. The subjects were randomly allotted to either Group I (12, Deep Subfascial) or Group II (12, Subfascial). All patients were evaluated objectively for facial nerve injury post-operatively and subjectively for quality of life in the form of a questionnaire post-operatively for 6 months. The data were analyzed using simple descriptive statistics, mean standard deviation, Wilcoxon paired t test, Friedman's test, and Mann Whitney U test. RESULTS: The comparison of the difference between the groups for postoperative facial nerve function at various time intervals did not give any significant differences (p > 0.05). In terms of quality of life there was a significant difference at 1 month post-operatively (p < 0.05) amidst the two approaches, however, 6-month follow-up revealed that there is no significant difference between the two approaches (p > 0.05). CONCLUSION: The study reveals that both the approaches are safe in terms of facial nerve injury and quality of life long term.

Effectiveness of platelet-rich fibrin in the management of pain and delayed wound healing associated with established alveolar osteitis (dry socket).

OBJECTIVE: To assess the efficacy of platelet-rich fibrin (PRF) on the pain and healing of the extraction socket related with established alveolar osteitis (dry socket, AO) after the removal of maxillary and mandibular molars. MATERIALS AND METHODS: One hundred consecutive adult patients with age group ranging from 18 to 40 years along with established dry socket after maxillary and mandibular molar extractions who have not received any treatment for the same were included in this single-arm clinical trial. PRF was placed in the maxillary and mandibular molar extraction sockets after adequate irrigation of the socket. All the patients evaluated for the various study variables which include pain, degree of inflammation, and healthy granulation tissue formation (wound healing) at the 1st, 3rd, 7th, and 14th post-PRF placement day in the alveolar socket. Data were analyzed using Shapiro-Wilk's test, Chi-square test and/or Student's t-test, Friedman's test, Wilcoxon signed-rank test, and Bonferroni test, with the significance level set at P < 0.05. RESULTS: There was significant reduction in pain associated with AO at the 3rd and 7th post-PRF placement day in the extraction socket along with mark decrease in the degree of inflammation at the 3rd post-PRF placement day, and there was better wound healing by the end of the 2nd week. CONCLUSION: The use of PRF in this clinical trial illustrates the promising results in terms of reduced pain and better healing in the patients with sustained AO.

Treatment of Mandibular Angle Fractures with Single Three-Dimensional Locking Miniplates without Maxillomandibular Fixation: How Much Fixation Is Required?

The aim of this simple nonrandomized and observational study was to evaluate the efficacy of single three-dimensional (3D) plate for the treatment of mandibular angle fractures without maxillomandibular fixation. A total of 30 patients with noncomminuted fractures of mandibular angle requiring open reduction and internal fixation were included in the study. All the patients were treated by open reduction and internal fixation using single 3D titanium locking miniplate placed with the help of transbuccal trocar or Synthes 90-degree hand piece and screw driver. 3D locking titanium miniplates used in our study was four-holed, box-shaped plate, and screws with 2 mm diameter and 8 mm length. The following clinical parameters were assessed for each patient at each follow-up visit: pain (visual analog scale: 0-5), swelling (visual analog scale: 0-5), mouth opening, infection, paresthesia, hardware failure (plate fracture), occlusal discrepancies, and mobility between fracture fragments. A significant decrease in pain level was seen during the follow-up visits. No statistically significant changes were seen in swelling, but mouth opening increased in the subsequent visits. Also better results were seen in terms of fracture stability and occlusion in the postoperative period. Two cases of infection and two cases of hardware failure were noted in sixth postoperative week. 3D plating system is an easy to use alternative to conventional miniplates to treat mandibular angle fractures that uses lesser foreign material, thus reducing the operative time and overall cost of the treatment. Better fracture stability and occlusion was also achieved using the 3D plating system.

Assessment of Bite Force in Patients Treated with 2.0-mm Traditional Miniplates versus 2.0-mm Locking Plates for Mandibular Fracture.

The objective of this study is to analyze the difference in bite forces in patients treated for mandibular fractures with 2.0 mm conventional and locking titanium plating system. A randomized study was performed for the treatment of fractures of mandible. In this study, 20 adult patients with isolated mandibular fracture were included. The patients were randomly allocated into two groups, that is, Group I-2.0 mm nonlocking (traditional) and Group II-2.0 mm locking plates. Bite force was evaluated at 1st, 3rd, and 6th weeks. Comparison of all the assessed parameters between both the groups depicted no significant difference in terms of pain, swelling including the incidence of infection, paresthesia, and hardware failure. Although same was true in case of bite force between both the groups at various time intervals, there was statistically significant increase in the bite force within the group comprising patients in whom locking plates was used between 1st and 3rd weeks follow-up period and highly significant increase in bite force between 1st and 6th weeks of follow-up period. The rapid improvement of bite force values when locking plates were used implies that the locking plate can be used in preference to conventional plates to achieve early mobilization with assured stability in the treatment of mandibular fractures.

Pre-emptive effect of dexamethasone injection and consumption on post-operative swelling, pain, and trismus after third molar surgery. A prospective, double blind and randomized study.

AIM: To evaluate the preventative effect of intravenous 4 mg of dexamethasone and 8 mg oral dexamethasone on post-operative pain, swelling and trismus after the surgical extraction of mandibular third molars. MATERIALS AND METHODS: A randomized clinical trial comprised of 200 patients (control group I intravenous and experimental group II orally) with impacted lower third molars, average age 20.8 years with no local or systemic problems, with bilateral impacted lower third molars, were operated under local anesthesia. Group I was given 4 mg IV and group II was given 8 mg orally of dexamethasone 1 h before procedure. The choice of which side to operate first and the amount of concentration of medication to use was made randomly and double-blindly. Post-operative pain was evaluated using a visual analog scale (VAS) and the degree of swelling was evaluated through facial reference points' variation. The presence of trismus was analyzed through measurement of the interincisal distance (IID). These assessments were obtained before the operation and 24 h, 48 h and 7th POD. RESULTS: No significant difference was found in facial swelling and trismus between IV 4 mg injection and oral 8 mg consumption after lower third molar surgery (student t test P > 0.05). The visual analogue scale scores for pain assessment showed no significant difference between IV injection and oral route of dexamethasone (student t test P > 0.05). CONCLUSION: Patients can be administered 8 mg oral dexamethasone is as effective as 4 mg intra venous route without much difference in final outcome at any given point of time.

Fractures of the mandibular condyle--Open versus closed--A treatment dilemma.

PURPOSE: The aim of this prospective randomized controlled study was to evaluate the superiority of open method of treatment of mandibular condylar fracture over closed method of treatment by comparing them. METHODS AND PATIENTS: Out of a total of 50 randomized patients fractures of the mandibular condylar process completed the study and were evaluated. All fractures were displaced, being either angulated between 10° and 45°. The follow-up examinations 1st day, 2nd day, 1st week, 2nd week, 6th week, and 6 months following treatment included clinical evaluation of functional and subjective parameters including visual analogue scale for pain and the interincisal mouth opening, malocclusion, deviation of mouth, range of motion, radiographic measurements were done. RESULTS: No significant difference was found between the two groups in the maximal interincisal opening, range of movements and TMJ pain. However statistically significant difference was seen in the anatomic reduction of condyle, shortening of ascending ramus, occlusal status and deviation on mouth opening on immediate postoperative phase. CONCLUSION: Both treatment options for condylar fractures of the mandible yielded acceptable results. However, a statistically significant difference was seen in the anatomic reduction of the condyle and there was no deviation on maximum mouth opening in patients treated with open reduction and internal fixation which suggests its superiority over closed method.
