Background: Existing literature lacks high-quality evidence regarding the ideal intraoperative positive end-expiratory pressure (PEEP) to minimize postoperative pulmonary complications (PPCs). We hypothesized that applying individualized PEEP derived from electrical impedance tomography would reduce the severity of postoperative lung aeration loss, deterioration in oxygenation, and PPC incidence. Methods: A pilot feasibility study was conducted on 36 patients who underwent open abdominal oncologic surgery. The patients were randomized to receive individualized PEEP or conventional PEEP at 4 cmH2O. The primary outcome was the impact of individualized PEEP on changes in the modified lung ultrasound score (MLUS) derived from preoperative and postoperative lung ultrasonography. A higher MLUS indicated greater lung aeration loss. The secondary outcomes were the PaO2/FiO2 ratio and PPC incidence. Results: A significant increase in the postoperative MLUS (12.0 ± 3.6 vs 7.9 ± 2.1, P < 0.001) and a significant difference between the postoperative and preoperative MLUS values (7.0 ± 3.3 vs 3.0 ± 1.6, P < 0.001) were found in the conventional PEEP group, indicating increased lung aeration loss. In the conventional PEEP group, the intraoperative PaO2/FiO2 ratios were significantly lower but not the postoperative ratios. The PPC incidence was not significantly different between the groups. Post-hoc analysis showed the increase in lung aeration loss and deterioration of intraoperative oxygenation correlated with the deviation from the individualized PEEP. Conclusions Individualized PEEP appears to protect against lung aeration loss and intraoperative oxygenation deterioration. The advantage was greater in patients whose individualized PEEP deviated more from the conventional PEEP.

Objectives:The uses of devices of electromagnetic waves(EMWs)are increasing day by day.Similarly,the gen-eration of the waves is increasing.The frequency spectrum of the generation of waves is also increased.In this manuscript,an analysis of the high frequency EMWs has been made by the electric fields generated due to the exposure of 5th generation(5 G)of mobile phones. Methods:Due to the emission of waves from the towers,the electric field is generated around the transmission tower of mobile phones.The electric fields are computed by the power of the transmission tower.The electric fields across the biological tissues/cells are also computed when the EMWs penetrate inside the body.The electric fields are made across the organs of different depths inside the body. Results:The induced electric fields inside the organs of the human beings are responsible for the absorption of energy from high frequency EMWs.The absorbed amount of energy from high frequency waves may become the cause of harmful effects on the life of organs of human beings. Conclusion:In this manuscript,after analysis of the computed electric fields inside the organs of human beings,it is concluded that the EMWs of 5 G spectrum of mobile phone towers may more harmful for the life of organs as 4th generation(4 G)spectrum of mobile phone waves.The energy absorption by the 4 G spectrum is lower than 5 G spectrum due to the range of frequency of waves.The effects on the pancreas,retina,skin,intestine,spleen,stomach and uterus are more than low water content organs like nails,bone,teeth etc.

Monogenic disorders are traditionally attributed to the presence of mutations in a single gene. However, recent advancements in genomics have revealed instances where the phenotypic expression of apparently monogenic disorders cannot be fully explained by mutations in a single gene alone. This review article aims to explore the emerging concept of digenic or oligogenic inheritance in seemingly monogenic disorders. We discuss the underlying mechanisms, clinical implications, and the challenges associated with deciphering the contribution of multiple genes in the development and manifestation of such disorders. We present relevant studies and highlight the importance of adopting a broader genetic approach in understanding the complex genetic architecture of these conditions.

Purpose: Uncertainty exists about whether early laparoscopic cholecystectomy (LC) is an appropriate surgical treatment for acute calculous cholecystitis. This study aimed to compare early vs. late LC for acute calculous cholecystitis regarding intraoperative difficulty and postoperative outcomes. Methods: This was a prospective randomized study carried out between December 2015 and June 2017; 60 patients with acute calculous cholecystitis were divided into two groups (early and delayed groups), each comprising 30 patients. Thirty patients treated with LC within 3 to 5 days of arrival at the hospital were assigned to the early group. The other 30 patients were placed in the delayed group, first treated conservatively, and followed by LC 3 to 6 weeks later. Results: The conversion rates in both groups were 6.7% and 0%, respectively (p = 0.143). The operating time was 56.67 ± 11.70 minutes in the early group and 75.67 ± 20.52 minutes in the delayed group (p = 0.001), and both groups observed equal levels of postoperative complications. Early LC patients, on the other hand, required much fewer postoperative hospital stay (3.40 ± 1.99 vs. 6.27 ± 2.90 days, p = 0.006). Conclusion Considering shorter operative time and hospital stay without significant increase of open conversion rates, early LC might have benefits over late LC.

Objectives: Obstructive Sleep apnea (OSA) is characterized by complete or partial obstruction of upper airflow despite the effort to breathe, leading to hypoxemia and hypercapnia. The resultant apnea causes sleep fragmentation, which in turn increases sympathetic activity, decreases insulin sensitivity and glucose uptake, and stimulates hepatic gluconeogenesis that ultimately leads to type 2 diabetes. Most studies exploring the effect of continuous positive airway pressure on insulin sensitivity have showed a positive effect. However, there is no evidence on the effect of mandibular advancement device on insulin resistance (IR). This study was aimed to evaluate the effect of mandibular advancement splint (MAS) on IR in patients with OSA. Methods: The present study was conducted at Department of Prosthodontics, Dental College Azamgarh, from June 2015 to July 2017. Sixty eight dentulous patients with type 2 diabetes and mild to moderate OSA and with stable diabetic regimen were included in the study. A MAS was fabricated and fixed at 70% of the maximum mandibular protrusion recorded. Patients that were comfortable with MAS after one month were assessed for apnea-hypopnea index, mean oxygen saturation, and IR at baseline, 6 months, and 1 year after wearing MAS. Results: An improvement in insulin sensitivity was observed at 6 months for mild OSA patients (p=0.001). For moderate OSA patients, no significant improvement was observed following MAS use (p>0.05). Conclusions The finding suggested that MAS is effective in improving IR in mild OSA patients.

OBJECTIVES: The objective of this study was to highlight the role of lateral arthroplasty along with interposition of the buccal fat pad (BFP) in the management of Sawhney type III temporomandibular joint (TMJ) ankylosis. MATERIALS AND METHODS: Ten patients with TMJ ankylosis (7 unilateral and 3 bilateral, total of 13 joints) were treated with lateral arthroplasty and BFP interposition. The bony bridge of the ankylotic mass on the lateral aspect was resected, leaving a distance of 1.5 to 2.0 cm from the base of the skull to the neck of the condyle. The condyle was left intact. Coronoidectomy was performed on the ipsilateral side via the same approach in all cases. The inter-incisal opening was measured at that time, and if it was less than 35 mm, contralateral coronoidectomy was performed by using the intra-oral approach. After satisfactory inter-incisal mouth opening (≥35 mm) was achieved, the TMJ surgical site was revisited, and BFP was retrieved and used to cover the lateral aspect of the medially placed condyle. RESULTS: With lateral arthroplasty, the medially displaced condyle can be left in-situ to maintain the mandibular ramal height and function and to act as a growth center in children. Interposition of the BFP prevents reformation of the lateral bony bridge that was removed. CONCLUSION Lateral arthroplasty along with interpositioning of the BFP is a novel technique for managing Sawhney type III ankylosis that achieves management goals while avoiding complex and advanced reconstructive surgical procedures.

BACKGROUND: Street vendors spend relatively more time near roadways and are vulnerable to air pollution related health disorders. However, there is limited information on the quality of the air they breathe. The objectives of this present study were to calculate the mass concentration of atmospheric particulate matter (PM) in eight size fractions (PM0.4–0.7, PM0.7–1.1, PM1.1–2.1, PM2.1–3.3, PM3.3–4.7, PM4.7–5.8, PM5.8–9.0, and PM9.0-–0µm) at commercial (CML) and residential site (RSL) in Dehradun city from November 2015 to May 2016. To estimate the corresponding respiratory deposition dose (RDDs) in alveolar (AL), tracheobronchial (TB), and head airway (HD) region on street vendors working at CML and RSL. To find the association of atmospheric PM with RDDs and the incidence of respiratory related disorders among street vendors. METHODS: Andersen cascade impactor was employed for calculating the PM mass concentration. Questionnaire based health survey among street vendors were carried out through personal interview. RESULTS: A significant difference (p < 0.05; t-test) between the mean PM0.4–10µm mass concentration at CML and RSL was observed with (mean±SD) 84.05±14.5 and 77.23±11.7 µgm−3, respectively. RDDs in AL, TB and HD region at CML was observed to be 9.9, 7.8, and 7.3% higher than at RSL, respectively. Health survey revealed 1.62, 0.96, 0.04, and 0.57 times higher incidence of cold, cough, breathlessness, and chest pain, respectively with street vendors at CML compared to RSL. CONCLUSION: The site characteristics plays a major role in the respiratory health status of street vendors at Dehradun.

The management of multiple complicated injured patients remains a great challenge despite advance- ments in modern medical care. We present a rare case of bilateral unstable pelvic fractures associated with bilateral segmental femoral shaft fractures.We have proposed a mechanism of such complex injury pattern and discussed the plan of management. We believe that a timely and aggressive surgical intervention to fix all the major fractures soon after medically stabilizing the patient helped our patient to overcome these serious and lethal injuries. It is necessary to establish an optimal protocol for management of such complex fractures by conducting prospective and multicentric studies in the future.

PURPOSEBoth cannulated cancellous screw (CCS) and sliding hip screw (SHS) are used in femoral neck fracture fixations, but which is superior is yet to be determined. This study was aimed to compare the clinicoradiological outcome of femoral neck fracture treated with SHS or CCS in young adults.

METHODSAdults (16e60 years) with femoral neck fracture were divided into Group 1 fixed with SHS and Group 2 fixed with three CCS after closed reduction. Pain relief, functional recovery and postoperative radiographs at 6 weeks, 3 months, 6 months and then yearly for upto 4 years were analyzed.

RESULTSGroup 1 (n=40) achieved radiological union at mean of 7.6 months, with the union rate of 87.5% (n=35), avascular necrosis (AVN) rate of 7.5% (n=3) and mean Harris Hip Score (HHS) of 86.15 at the end of 4 years. In Group 2 (n=45) these parameters were union at 7.1 months, union rate of 82.22% (n=37), AVN rate of 6.67% (n=3) and HHS of 88.65. Comparative results were statistically insignificant.

CONCLUSIONThere is no significant difference in clinicoradiological outcome between the two implants.
