Reconstruction of the choana in a teenager with congenital unilateral choanal atresia after multiple choanal surgery. Case report

Choanal atresia (CA) is a congenital pathology, the frequency of which currently stands at 1 in 8000 newborns. The cause of congenital choanal atresia has not been definitively established at the moment. Diagnosis of CA often is made by pediatricians or neonatologists in the ICU oh the maternity hospital. In case of bilateral CA diagnosis is often not difficult and the diagnosis is often suggested right after labor due to asphyxia, but with a unilateral process, children can live for years without nasal obstruction in case of compensated nasal breathing. Today approaches to CA repair in children remain controversial. And if, in a bilateral process, surgical intervention is recommended to be done as early as possible, in case of the correction of the unilateral process may be postponed until older age. There is also no clear opinion on the approaches to surgical approaches, the use of protectors, the duration of their installation and the type of protector used is also controversial. The article describes a clinical case of adolescent with bilateral CA with multiple choanoplasty surgeries and restenosis. The child was admitted to Otorhinolaryngology Department of the Veltischev Research and Clinical Institute of Pediatrics and Children surgery. Despite the diagnosis that was made on time, the patient managed to improve nasal breathing only by the age of 15 after choanal reconstruction.

ПРИМЕНЕНИЕ МЕМБРАНОПРОТЕКТОРОВ ДЛЯ ЛЕЧЕНИЯ ПАЦИЕНТОВ С "МОЛНИЕНОСНОЙ" ФОРМОЙ ОСТРОГО ПАНКРЕАТИТА

Background Acute pancreatitis, which causes a huge number of complications, has been and remains one of the most serious diseases in urgent surgery. Despite the currently existing algorithms for the diagnosis and treatment of acute pancreatitis, a number of unresolved issues remain that require further studying. Purpose. To substantiate the effectiveness of the use of membrane protectors in the complex treatment of acute pancreatitis. Material and methods. The retrospective stage (2016–2018) included 30 patients diagnosed with acute pancreatitis who received standard treatment. The prospective stage (2018–2020) included 31 patients diagnosed with acute pancreatitis (AP). In addition to the complex treatment for these patiets, membrane protectors were used in the pre- and postoperative period. The groups were comparable in age and extent of the pancreatic lesion. During the study, in addition to the standard surgical treatment, the patients received the drug “Neurox” in the pre- and postoperative period. Results. The use of membrane protectors is justified, on day 14 there was a statistical decrease in erythrocyte membrane ruptures. Discussion. In recent years, there has been an increase in the number of studies investigating the effect of membrane protective therapy on the course of acute pancreatitis in general, and destructive forms in particular.Some publications note the effectiveness of combined membrane protective and antioxidant therapy in destructive pancreatitis. Conclusion. The use of membrane protectors in the complex treatment of acute pancreatitis is pathogenetically justified and can be used for the therapeutic correction of acute pancreatitis, taking into account the developing morphofunctional processes.

Prevalence and Factors Associated With Occupational Noise-Induced Hearing Loss Among Palm Oil Mill Workers in Selangor, Malaysia.

Introduction Occupational noise-induced hearing loss (NIHL) continues to be a significant public health issue globally, with Malaysia being no exception. In Malaysia, the majority of NIHL cases are reported from the manufacturing sector, with Selangor among the states with the highest number of confirmed cases. This study aimed to assess the prevalence of and factors associated with occupational NIHL among palm oil mill workers in Selangor, Malaysia. Methods A cross-sectional study was conducted to analyze the data from the data collection form, noise risk assessment reports, and audiometric test results done between 2021 and 2022 with a comparable baseline audiometric test. Results A total of 143 participants from three palm oil mills joined this study. The prevalence of NIHL was 42.7% (n = 61). Following the logistic regression model, NIHL was significantly associated with a duration of employment of 10 years and above, a history of occupational noise exposure at the previous workplace, and the use of personal hearing protectors at the current workplace with an adjusted OR of 2.41 (95% CI (1.14, 5.07)), 5.89 (95% CI (2.38, 14.53)), and 0.36 (95% CI (0.16, 0.83)), respectively. Conclusion The prevalence of NIHL among the study participants was high, and the associated factors are modifiable factors that can be prevented with a comprehensive hearing conservation program in the palm oil mills.

Is the use of gonad protection protectors necessary during infants chest radiography?

Introduction and objectivesTo compare gonad doses with and without a gonad protector and to optimize the use of gonadal protectors in infants thorax radiography. Materials and methodsTwo pediatric anthropomorphic phantoms are used: an X-ray system for KXO-50SS/DRX-3724HD, and a digital radiography system for CALNEO Smart C12, with and without a gonad protector during infants thorax radiography. A real time skin dosimeter is placed on the X-ray system, and a real time skin dosimeter is inserted on the front side of the mammary gland, the front and back sides of the true pelvis level, and on the ovaries and testes. The X-ray system is irradiated 15 times using phantoms with and without a gonad protector. The measured entrance patient doses values of for the real time skin dosimeter are compared for each phantom, with and without the gonad protector. ResultsThe medium of measured entrance patient doses values for front side dose of the true pelvis level with and without the protector are 10.00 and 5.00 μGy at newborn, and 10.00 and 0.00μGy at one year, respectively. The medium of measured entrance patient doses values for the back side dose of the true pelvis level with and without the protector are 0.00 and 0.00 μGy at both newborn one year, respectively. The measured entrance patient doses cannot be detected in the ovaries and testes with or without the protector. No significant differences are observed in the measured entrance patient doses values for the front and back side doses of the pelvis, ovaries, and testes at newborn and one year, with and without the protector (p>0.05). ConclusionsNo significant difference was observed in gonad dose measurements with and without the gonad protector during infants chest radiography. We believe that gonadal protector wearing is not necessary.

PROFILE OF RISK FACTORS FOR ACOUSTIC TRAUMA IN 105 HOWITZER CANNON SHOOTER STUDENTS AT THE PUSAT PENDIDIKAN ARTILERI MEDAN-CIMAHI

Acoustic Trauma is hearing loss caused by short period high frequency noise. Hearing loss can occur in military, because it uses the main tools of the weaponry system, such as guns, military vehicles, and explosions. This research aims to determine the description of risk factors for acoustic trauma, patterns of hearing protector use, and ear complaints among students of Pusdik Armed who perform 105 Howitzer Cannon shooting practice. This study used a descriptive method with a cross sectional design on the students of Pusdik Armed who perform 105 Howitzer Cannon shooting practice. The sampling technique used total sampling with 103 population. The research instrument was secondary data from the public dedication questionnaire of Dr Asti Kristianti, Sp.THT-BKL, M.Kes. The results showed a description of the risk factors for acoustic trauma in Pusdik Armed Students who perform Howitzer 105 Cannon shooting practice mostly due to high noise exposure (64.1%), smoking history (60.2%), using PLDs (59.2%), a minority do not wear hearing protectors (12.6%), and the use of ototoxic drugs (1.9%), and no one has hypertension and a family history of hearing loss. The pattern of using hearing protectors during 105 Howitzer Cannon shooting practice is from students who use ear protectors (87.4%), some use ear protectors during training (72.8%). The description of ear complaints before doing Howitzer 105 Cannon shooting practice mostly did not experience ear complaints either before (82.5%) or after (76.6%). Therefore, it is necessary to require the use of ear protective equipment for cannon shooters.

Orthopedic injuries in mountain bike: an integrative review

Mountain biking (MTB), also known as off-road cycling, refers to cycling on purpose-built trails in mountains and other unpaved surfaces. This study proposes an integrative review of the literature to highlight the most common orthopedic injuries associated with the practice of MTB. A review study was conducted, using periodicals published in the PubMed databases and the Virtual Health Library (VHL) as a basis. The results of this research were divided into: Table 1 (Characteristics of the productions included in the review) and Table 2 (Synthesis of the productions according to the main results). The prevalent injuries worthy of special attention are related to the upper limb, such as clavicle fractures and dislocations, in addition to wrist injuries, often resulting from falls and direct impacts. The importance of preventive measures, such as the appropriate use of protective equipment, including helmets, gloves and wrist protectors, is highlighted.

'Cultural Insights into Adults' Hearing Awareness and Personal Listening Device Habits: A Survey Study.

The aim of this study was to investigate adults' habits regarding personal listening devices (PLDs), associated factors such as tinnitus and hearing threshold shift, and their knowledge of safety measures, including the use of hearing protectors in noisy environments. A cross-sectional survey was designed and distributed online. Participants between the ages of 18 and 40 years were invited to complete the survey. The online survey was filled out by 274 individuals with an average age of 24.2 years (SD= 5.1 years). Based on age, the participants were grouped into young adults (18-23 years old, 151 participants) and adults (24-40 years old, 123 participants). The estimation of noise exposure was calculated based on self-reported responses of PLD use. Two categories emerged from this calculation: the participants with exposure lower than 80 dB were in the low exposure category (N: 196, 62.9 dB), while the participants with exposure higher than 80 dB were in the high exposure category (N: 78, 89.9 dB). Based on the age categories, most of the questionnaire answers were similar between the young adults and the adults, revealing similar habits in using their PLDs. However, the investigation based on exposure revealed differences, as the participants with high exposure levels were more likely to have hobbies that involved noise, and they were less likely to obtain hearing evaluations. Among the participants, 30% used their devices at the maximum volume level and on a daily basis. 33.5% reported experiencing worsening in hearing, 2.4% reported persistent tinnitus, 94.1% knew that hearing protectors were available but only 20.7% reported using hearing protectors. The study concludes that adults are at risk of hearing loss due to unsafe listening habits. A discrepancy between knowledge and practice is apparent and needs to be addressed in young adults by increasing awareness of hearing loss, hearing protection and annual hearing evaluation.

Studi Kualitatif Gangguan Pendengaran Akibat Bising di Bengkel Bubut X Sidoarjo

Noise is one of the most dangerous factors in the workplace. Noise can lead to hearing impairment and the risk of temporary or permanent damage to the sense of hearing after exposure for a certain period of time without the use of adequate protective equipment. The aim of the study is to find out the picture of hearing impairment due to noise experienced by workers X Sidoarjo. This study uses a qualitative descriptive approach with observational methods. The result of this study was that 2 out of 10 informants suffered from hearing impairment. The main source of noise in the powder workshop X Sidoarjo is the powdering machines and tooling and scrubbing. Prevention can be done through the use of ear protectors against workers and the implementation of socialization of safety and health at work in order to create a safe and secure workplace environment.

Sudden Cardiac Death: An Update on Commotio Cordis.

Sudden cardiac death (SCD) is one of the leading causes of cardiovascular mortality, and it is caused by a diverse array of conditions. Among these is commotio cordis, a relatively infrequent but still significant cause, often seen in young athletes involved in competitive or recreational sports. It is known to be caused by blunt trauma to the chest wall resulting in life-threatening arrhythmia (typically ventricular fibrillation). The current understanding pertains to blunt trauma to the precordium, with an outcome depending on factors such as the type of stimulus, the force of impact, the qualities of the projectile (shape, size, and density), the site of impact, and the timing of impact in relation to the cardiac cycle. In the management of commotio cordis,a history of preceding blunt chest trauma is usually encountered. Imaging is mostly unremarkable except for ECG, which may show malignant ventricular arrhythmias. Treatment is focused on emergent resuscitation with the advanced cardiac life support protocol algorithm, with extensive workup following the return of spontaneous circulation. In the absence of underlying cardiovascular pathologies, implantable cardiac defibrillator insertion is not beneficial, and patients can even resume physical activity if the workup is unremarkable. Proper follow-up is also key in the management and monitoring of re-entrant ventricular arrhythmias, which are amenable to ablative therapy. Prevention of this condition involves protecting the chest wall against blunt trauma, especially with the use of safety balls and chest protectors in certain high-risk sporting activities. This study aims to elucidate the current epidemiology and clinical management of SCD with a particular focus on a rarely explored etiology, commotio cordis.

Studi Eksperimen Laju Pertumbuhan Biofouling Pada Pelat Baja Dan Aluminium Dengan Lapisan Pelindung Lilin Dan Minyak Di Pantai Boom Banyuwangi

Indonesia is a maritime country with a tropical climate and has various biofouling species. The existence of fouling in a marine structure has a large impact on losses if it is not addressed immediately. Antifouling is needed to overcome the presence of fouling. Various development efforts to inhibit, prevent and eliminate biofouling continue to be made. Generally, the method used by the public is by using commercial antifoulant protective paints with heavy metal main components such as TBT (tri-n-butyl tin). However, currently various studies have proven that TBT compounds are not only toxic to biofouling biota but also harmful to other marine organisms. Further research is needed to find antifouling alternatives that do not contain toxic compounds and are more environmentally friendly. This study was designed to determine the growth rate of marine growth in steel and aluminum plate materials at Boom Banyuwangi Beach by using a protective coating in the form of oil and wax. From the results of the research designed, it can be analyzed the efficiency of using protective layers of oil and wax with steel and aluminum materials on the growth rate of marine growth according to the conditions of the waters of Boom Banyuwangi Beach. The use of oil protectors on steel and aluminum test specimens resulted in more efficient results in inhibiting the growth rate of biofouling than the use of wax protectors

Impulse noise measurement in view of noise hazard assessment and use of hearing protectors

Experience shows the occurrence of situations when the measurements of impulse noise parameters are made with measurement equipment unsuitable for such conditions. The results of using such equipment were compared with the results of using equipment with a sufficiently large upper limit of the measurement range. The analysis was carried out on the example of noise generated during shots from a Mossberg smooth-bore shotgun and AKM rifle, as well as produced in the forge. The use of the unsuitable equipment allowed to indicate the exceeding of the exposure limit value of the peak value of the signal (LC peak), but this is not always possible when determining the energy properties of the signal (L EX,8h). While the inadequate properties of the measurement equipment will generally not prevent the conclusion that noise in a particular workplace is hazardous to hearing, the results of measurements cannot be used to select hearing protectors.

Effectiveness of Motivational Interviewing in Increasing Use of Hearing Protection Devices Among Agricultural Producers.

Agricultural producers are frequently exposed to noise that is hazardous to their hearing and cardiovascular health, and have among the highest rates of noise-induced hearing loss of all occupations. However, despite information-sharing approaches, few producers wear sufficient hearing protection. There is a need to develop effective methods of protecting producers from their noise exposure. We provided a series of 2 to 3 short (30-minute) telephone-based motivational interviewing (MI) sessions to noise-exposed agricultural producers. We assessed intervention effectiveness through changes in measuring hearing protector use pre- and post-intervention using a one-group pre/posttest design. The sample (N = 29) predominantly consisted of crop producers from Michigan. The mean percentage of time hearing protection was used increased from 44.9% to 51.8% after the intervention, approximately a 7% increase (p =.105). Regression analysis suggested the relationship between intervention dose and use of hearing protection was not correlative. There was a marginal increase in the use of hearing protection after the intervention, although setting-specific increases in use were uneven. Intervention dose did not correlate with a change in hearing protection use. Further research is warranted to determine the effectiveness of MI, how it compares to information sharing, and to identify intervention dose parameters that promote efficiency.

Surgical Site Infections in Solid Organ Transplant Recipients

Surgical site infections (SSIs) are defined as superficial infections, deep incisional infections, and organ/organ space infections that occur within 30 days of the surgical procedure or up to 90 days if a prosthetic implant has been used. Incidence of SSI is highest in recipients of small bowel transplant, followed by liver, pancreas, and kidney transplant. These are diagnosed by the presence of at least one of the following: purulent discharge from the wound, organism identified from the specimen obtained from the site with culture/nonculture-based methods, evidence of infection on gross/histopathological examination or on imaging, or a clinical diagnosis of SSI by a physician. The spectrum of organisms implicated in SSIs in solid organ transplant recipients is more diverse due to underlying end-stage organ failure, need for immunosuppression, prolonged hospitalization, colonization or active infection in the deceased organ donor, contamination during organ transportation/preservation. SSI in solid organ transplant can be prevented leading to hospital stay and cost of transplantation. Minimizing surgical operative time, sterile and appropriate surgical technique and antimicrobial prophylaxis, management of patient comorbidities as well as glucose and temperature regulation are important for prevention of SSI. This article discusses useful preventive strategies for preventing SSI such as preoperative bathing, use of appropriate preoperative antibiotic prophylaxis, surgical site and hand preparation, use of wound protectors, drapes and gowns, incisional wound irrigation, adequate nutritional support, and use of perioperative oxygenation.

Role of single or double ringed circumferential wound protectors in reducing surgical site infections following colorectal resections. A systematic review.

ObjectiveThe objective of this article is to explore whether the use of single or double ringed wound protectors (WP) in patients undergoing colorectal resection (CRR) are associated with reduced risk of surgical site infections (SSI).Materials and methodsAnalysis was conducted according to PRISMA guidelines. With the help of expert local librarians, systematic search of medical databases like MEBASE, MEDLINE and PubMed was conducted to find appropriate randomized controlled trials (RCT) according to predefined inclusion criteria. The analysis of the pooled data was done using the principles of meta-analysis on statistical software RevMan version 5.ResultTwelve RCT on 2425 patients fulfilled the inclusion criteria. There were 1216 patients in the WP group and 1209 patients in the no-WP group. In the random effects model analysis, the use of WP during CRR was associated with the reduced risk of SSI [odds ratio 0.60, 95% CI (0.41–0.90), z = 2.49, P = 0.01]. However, there was significant heterogeneity (Tau2 = 0.22; Chi2 = 25.87, df = 11; (p = 0.007; I2 = 57%) among included studies.ConclusionUse of WP seems to reduce the risk of SSI and therefore, may routinely be used during both open and laparoscopic CRR.

Evaluation of Dental Injuries in Iranian Athletes: A Narrative Review

Background: Dental injury is an important public health problem that occurs in athletics. This study aimed to determine dental injuries in Iranian athletes. Methods: By searching related keywords in the Scopus, PubMed, Web of Science, Google Scholar, and EMBASE databases, as well as the reference list of the eligible articles, and related published studies in English and Persian by the end of 2020 were included in the study, and the required data were extracted from them. Results: Out of 475 papers initially identified, 10 satisfied the inclusion criteria and were fully evaluated accordingly. Most dental injuries belonged to combat disciplines, and the most common types of injuries were fractures and mobility in the maxillary incisors. Based on these studies, it was found that most reported injuries occurred in men during exercise. Studies have also shown that the lack of using dental protectors is one of the most important causes of injury, and the use of protectors is crucial in preventing dental injuries. Conclusions: It seems that the emphasis on the preventive role of the use of dental protectors in controlling and preventing the occurrence of dental injuries can be decisive in this regard.

The role of protectors: a UK perspective

Abstract Absent from English statute, trust protectors are notoriously ill-defined, and that term can take on vastly different meanings between jurisdictions, and between trust instruments. Protector problems are a more frequent feature in offshore trust litigation, in particular regarding the precise nature of protector powers, and whether these should be defined as fiduciary, personal or otherwise. In this article, we explore the UK perspective on the use and incorporation of trust protectors, in comparison to their use in the traditional offshore jurisdictions where they are particularly prevalent, and seemingly only increasing in stature and power, at times exercising genuinely discretionary review functions and sometimes holding powers that exceed those of their trustees. Different interpretations of the key protector power of veto are also explored, with reference to the recent alternate findings on this issue between the Jersey Courts in Piedmont and Riviera Trusts [2021] and the Supreme Court of Bermuda in Re the X Trusts [2021].

SP9.2.3 Role of single or double ringed circumferential wound protectors in reducing surgical site infections following colorectal resections: an evidence synthesis by the meta-analysis of randomized controlled trials

Abstract Objective The objective of this article is to explore whether the use of single or double ringed wound protectors (WP) in patients undergoing colorectal resection (CRR) is associated with reduced risk of surgical site infections (SSI). Method Analysis was conducted according to PRISMA guidelines. With the help of expert local librarian, systematic search of medical databases like MEBASE, MEDLINE and pubmed was conducted to find appropriate randomized controlled trials (RCT) according to predefined inclusion criteria. The analysis of the pooled data was done using the principles of meta-analysis on statistical software RevMan. Result Eighteen RCT on 3744 patients fulfilled the inclusion criteria. There were 1885 patients in the WP group and 1889 patients in the no-WP group. In the random effects model analysis, the use of WP during CRR was associated with the reduced risk of SSI [odds ratio 0.63, 95% CI (0.47–0.86), z= 2.94, p=0.003]. However, there was significant heterogeneity (Tau2 = 0.18; Chi2= 34.77, df = 17; (p=0.007; I2 = 51%) among included studies. Conclusion Use of WP seems to reduce the risk of SSI and therefore, may routinely be used during both open and laparoscopic CRR.

Exposure to Occupational Noise

Physical agent noise can be considered one of the main disturbances that compromise the occupational health of self-propelled forest machine operators. We evaluated whether occupational noise levels emitted by self-propelled forest machines employed in the full tree system are in accordance with both the National Institute for Occupational Safety and Health and ISO 1999:2013 standards, while also proposing mitigating measures aimed at protecting the operators hearing. Seventeen operators, who performed wood harvesting operations in Eucalyptus forests in Brazil, were analyzed. Noise levels were collected in a daily shift of eight hours as recommended by the Acoustics – Determination of occupational noise exposure - Engineering method for full-day measurements (ISO 9612:2009). The standards adopted for the evaluation were the exposure action value of 80 dBA and the exposure limit of 85 dBA based on the National Institute for Occupational Safety and Health – NIOSH and on Acoustics – Estimation of noise-induced hearing loss (ISO 1999:2013) Directive 2003/10/EC. The operators were arranged in homogeneous groups according to the Acoustics recommendation – Determination of occupational noise exposure - Engineering method for full-day measurements (ISO 9612:2009), classified by the operations of felling, skidding of tree bundles and bucking. The results showed that 17 self-propelled forest machines exceeded the exposure action value of 80 dBA, of which 10 machines exceeded the exposure limit of 85 dBA. It was concluded that the levels of occupational noise emitted by self-propelled forest machines used in the full tree system are higher than those recommended by both standards, National Institute for Occupational Safety and Health and ISO 1999:2013. Therefore, the allocation of self-propelled forest machines to homogeneous groups allows inferring mitigation actions that protect operators' hearing. The correct use of hearing protectors during the daily workday provides hearing protection for operators in mechanized wood harvesting. Adoption of actions such as maintenance of cabin seals and mechanical components, breaks for fatigue relief, reduction of daily working hours and rotation of operators in different self-propelled forest machines can mitigate the damage to the occupational health of operators.
