Background Gastric and colorectal cancer (CRC) are both one of the most common cancers worldwide. In many countries fecal immunochemical tests (FIT)-based CRC screening has been implemented. We investigated if FIT can also be applied for detection of H. pylori, the main risk factor for gastric cancer. Methods This prospective study included participants over 18 years of age referred for urea breath test (UBT). Patients were excluded if they had used antibiotics/bismuth in the past 4 weeks, or a proton pomp inhibitor (PPI) in the past 2 weeks. Participants underwent UBT, ELISA stool antigen test in standard feces tube (SAT), ELISA stool antigen test in FIT tube (Hp-FIT), and blood sampling, and completed a questionnaire on user friendliness. UBT results were used as reference. Results A total of 182 patients were included (37.4% male, median age 52.4 years (IQR 22.4)). Of these, 60 (33.0%) tested H. pylori positive. SAT and Hp-FIT showed comparable overall accuracy 71.1% (95%CI 63.2–78.3) vs. 77.6% (95%CI 70.4–83.8), respectively (p = 0.97). Sensitivity of SAT was 91.8% (95%CI 80.4–97.7) versus 94.2% (95%CI 84.1–98.9) of Hp-FIT (p = 0.98). Serology scored low with an overall accuracy of 49.7% (95%CI 41.7–57.7). Hp-FIT showed the highest overall user convenience. Conclusions FIT can be used with high accuracy and sensitivity for diagnosis of H. pylori and is rated as the most convenient test. Non-invasive Hp-FIT test is highly promising for combined upper and lower gastrointestinal (pre-) cancerous screening. Further research should investigate the clinical implications, benefits and cost-effectiveness of such an approach.

Objective: Foreign body aspiration is a preventable cause of mortality and morbidity especially in younger than three years old children. The aim of this study is to determine the risk factors, causes and prognosis in patients with foreign body aspiration. Method: In this study, laboratory and examination findings of 35 patients who underwent bronchoscopy, because of suspected foreign body aspiration, were retrospectively analyzed. Results: Of the 35 patients included in the study, 19 were boys and 16 were girls. The mean age was 3,2. The most causes of application were cough, and wheezing. Foreign body was detected in the right main bronchus in 62,8%, in the left main bronchus in 25,7%, in the trachea in 5,7% and in both bronchi in 5,7% of the patients. Conclusion: Early diagnosis and intervention significantly reduce the mortality and morbidity in foreign body aspirations. Prevention of foreign body aspirations is possible with the education of babysitters and family members.

Objective: Bacterial resistance is a major problem in recurrent urinary tract infections. These infections are seen commonly in children with urinary tract anomalies. In this study, we aimed to determine the bacterial resistance patterns ofantibiotics in pyelonephritis.Methods: One hundred two patients were reviewed with recurrent UTI during a pyelonephritis episode retrospectively.The patients were using some antibiotics at different times as prophylaxis. Routine biochemical parameters and ultrasonographic results were also evaluated.Results: Escherichia coli was detected as the main bacterial pathogen. Bacterial isolates were significantly found moreresistant to trimethoprim-sulfamethoxazole in children with the risk factor. On the other hand, the causative microorganisms were significantly found more resistant to some antibiotics in patients under prophylaxis.Conclusion: Frequent use of antibiotics due to recurrent infections might be a factor in the development of antibiotic resistance in children. However, drug selection should be made by considering antibiotic resistance rates. WOS:000681656200008 2-s2.0-85112094234

Despite most of the prolactinomas can be treated with endocrine therapy and/or surgery, a significant percentage of these tumors can be resistant to endocrine treatments and/or recur with prominent invasion into the surrounding anatomical structures. Hence, clinical, pathological, and molecular definitions of aggressive prolactinomas are important to guide for classical and novel treatment modalities. In this review, we aimed to define molecular endocrinological features of dopamine agonist-resistant and aggressive prolactinomas for designing future multimodality treatments. Besides surgery, temozolomide chemotherapy and radiotherapy, peptide receptor radionuclide therapy, estrogen pathway modulators, progesterone antagonists or agonists, mTOR/akt inhibitors, pasireotide, gefitinib/lapatinib, everolimus, and metformin are tested in preclinical models, anecdotal cases, and in small case series. Moreover, chorionic gonadotropin, gonadotropin releasing hormone, TGFβ and PRDM2 may seem like possible future targets for managing aggressive prolactinomas. Lastly, we discussed our management of a unique prolactinoma case by asking which tumors’ proliferative index (Ki67) increased from 5–6% to 26% in two subsequent surgeries performed in a 2-year period, exerted massive invasive growth, and secreted huge levels of prolactin leading up to levels of 1 605 671 ng/dl in blood.

Purpose To present the different clinical manifestations of rhino-orbital mucormycosis (ROM) co-infection in severe COVID-19 patients. Study design Prospective observational clinical study Methods Among 32,814 patients hospitalized with the diagnosis of COVID-19 between March 2020 and December 2020 in our center, eleven microbiologically confirmed ROM co-infection cases in severe COVID-19 patients were evaluated. Results There were nine men and two women with a mean age of 73.1 ± 7.7 years. Eight patients had uncontrolled type 2 diabetes with a mean diagnosis duration of 12.1 ± 4.4 years. All patients had COVID-19-associated acute respiratory distress syndrome and received corticosteroids. The mean time interval between COVID-19 diagnosis and ROM diagnosis was 14.4 ± 4.3 days. Seven patients (63.6%) had orbital apex syndrome, and four patients (36.4%) presented with orbital cellulitis. Endophthalmitis was detected in 54.5% of patients, and two of these patients developed retinoschisis. CT scan/MRI revealed sino-orbital involvement in all patients, and three of these had cerebral involvement at initial presentation. All patients received intravenous and retrobulbar liposomal amphotericin B and had undergone radical debridement of involved sinuses. Intravitreal liposomal amphotericin B injected in patients with endophthalmitis. Despite all measures, 63.6% of patients expired. Conclusions Severe COVID-19 is associated with a significant incidence of ROM with higher mortality rates due to immune dysregulation and the widespread use of steroids. Physicians should be aware of the possibility of this infection in patients with COVID-19. An aggressive multidisciplinary approach can help to reduce mortality.

Amaç: Bu çalışmanın amacı, günlük pediatrik nöroloji pratiğinde kromozomal mikrodizi analizinin (chromosomal microarray analysis, CMA) tanısal kullanışlılığını saptamak ve bu testi gerektiren hastalar için kılavuz olan klinik parametreler belirlemektir.Gereç ve Yöntemler: Pediatrik nöroloji kliniğimize 2018 ve 2020 yılları arasında çeşitli nedenlerle başvuran global gelişme geriliği/zihinsel yetersizlik (global developmental delay/intellectual disability, GDD/ID) olan 91 hastanın CMA sonuçları incelendi. CMA’da del/dup tespit edilen 34 (%37,4) hastanın ve normal CMA’ya sahip olan 57 (%62,6) hastanın demografik ve klinik verileri karşılaştırıldı.Bulgular: İki grup arasında yaş, cinsiyet, doğum şekli, doğum zamanı gibi demografik özellikler bakımından istatistiksel olarak anlamlı bir farklılık yoktu. Dismorfizm, hipotoni ve miyelinizasyon anormallikleri CMA’da del/dup olan hastalarda normal CMA’lı hastalara göre önemli ölçüde daha sıktı. Normal CMA grubunda makrosefali ve obezite sıklığı daha yüksekti ve bu grupta epileptik hastalardaki generalize konvulsiyon sıklığı daha yüksekti. Analizde del/dup saptanan 34 vakadan 19'u (%55,9) patojenik, 15'i (%44,1) klinik önemi bilinmeyen (muhtemelen patojenik, muhtemelen iyi huylu ve sınıflandırılamayan) olarak kabul edildi.Sonuç: CMA pahalı, zahmetli ve zaman alan bir test olduğundan, CMA talep edilirken klinik parametrelerin dikkate alınması yüksek tanısal verimlilik sağlayacaktır. Dismorfizm, hipotoni ve miyelinizasyon gecikmesi olan GDD/ID hastalarında kopya sayısı değişiklikleri yüksek olasılıkla saptanabilir. Bu hastalarda farklı bir etyoloji düşündüren herhangi bir bulgunun olmadığı durumlarda, CMA pediatrik nöroloji pratiğinde tercih edilebilir bir genetik analizdir., Aim: The aim of this study was to determine the diagnostic utility of chromosomal microarray analysis (CMA) in daily pediatric neurology practice and to identify the guiding clinical parameters for patients requiring this test.Material and Methods: The CMA results for 91 patients with global developmental delay/intellectual disability (GDD/ID) admitted to our pediatric neurology clinic for various reasons between 2018 and 2020 were examined. Demographical and clinical data for 34 patients (37.4%) in whom del/dup was determined at CMA and 57 patients (62.6%) with normal CMA were compared.Results: There was no statistically significant difference between two groups in terms of demographic characteristics such as age, gender, type of delivery, gestational age, etc. Dysmorphisms, hypotonia, myelination abnormalities were significantly more frequent in patients with del/dup than in patients with normal result. The frequency of macrocephaly and obesity was higher in the normal group, and that of generalized seizures was higher among epileptic patients in this group. Nineteen (55.9%) of the 34 cases who have del/dup detected at analysis were regarded as pathogenic, 15 (44.1%) as uncertain clinical significance (likely pathogenic, likely benign and no subclassification).Conclusion: Since CMA is an expensive, laborious, and time-consuming test, considering clinical parameters when requesting CMA will yield high diagnostic efficiency. A high possibility of copy number variants may be predicted in GDD/ID patients with dysmorphisms, hypotonia, and myelination delay. CMA should represent the genetic analysis of choice in pediatric neurology practice in case of no finding suggesting a different etiology in these patients.

Background/aim: Hantavirus is a rodent borne zoonosis caused by the members of the virus family Bunyaviridae, genus Hantavirus. In this study, we aimed to determine the role of peripheral blood leukocyte ratio in differential diagnosis of Hantavirus disease. Materials and methods: The medical records of patients at the Duzce University Medical Faculty were examined retrospectively. A total of 20 patients diagnosed with hantavirus infection confirmed by serologic tests were included in the study (Group 1). The other group consisted of 30 patients suspected of hantavirus infection but found negative (Group 2). Demographic, clinical and laboratory characteristics, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and lymphocyte/monocyte (LMR) ratios of both groups were compared. Results: As a result of the istatistics analysis, no difference was found between the groups' age, sex, and clinical complaints except lethargy-weakness (P = 0.004) and diarrhea (P < 0.001). Hemogram analysis showed a significant difference between the groups in terms of leukocyte, hemoglobin, hematocrit, platelet, mean platelet volume (P < 0.05) and PLR (P = 0.001) and LMR (P = 0.003) values from peripheral blood leukocyte ratios. Conclusion: In conclusion, NLR, PLR, and LMR ratios may be useful for clinicians in differential diagnosis of Hantavirus in patients presenting with similar symptoms of Hantavirus disease.

Purpose: Transgender, including gender diverse and nonbinary (trans), people experience significant health disparities. We aimed to better understand the health status and needs of Australian trans people to guide resources and health and well-being programs. Methods: This anonymous, cross-sectional online survey utilized nonprobability snowball sampling of Australian adults (18 years and over) who self-identified as trans between September 2017 and January 2018. This descriptive study assessed demographic data, community views on access to health care, health burden, access to health resources, and priorities for government funding in transgender health. Results: Of 928 participants, 37% reported female, 36% reported male, and 27% reported nonbinary gender identities. Despite 47% having tertiary qualifications, the unemployment rate was 19%, with 33% reporting discrimination in employment due to being trans. Discrimination in accessing health care was reported by 26% and verbal abuse and physical assault were reported by 63% and 22%, respectively. Lifetime diagnosis of depression was reported by 73% and anxiety by 67%. Sixty-three percent reported previous self-harm and 43% had attempted suicide. Autism spectrum disorder and attention-deficit/hyperactivity disorder were reported by 15% and 11%, respectively. The most preferred method of receiving health information was through online resources, with the most popular source being Reddit, an online peer discussion board. Better training for doctors in trans health issues was the top priority for government funding. Conclusions: Barriers, including widespread discrimination and unemployment, contribute to health inequity and prevalent mental health conditions. Better training for health professionals in the provision of safe, gender-affirming and general health care for trans people is urgently required.

Background Despite numerous national and international efforts to alleviate child growth faltering, it remains a global health challenge. There is a growing body of literature that recognizes the importance of women’s empowerment in a wide range of public health topics, such as the utilization of maternal healthcare services, agricultural productivity, and child nutrition. However, in Ethiopia, the relationship between women’s empowerment and child nutritional status is not studied at the national level. This study aimed to determine the association between women’s empowerment and growth faltering in under-5 children in Ethiopia. Methods The data source for this analysis is the 2016 Ethiopian Demographic and Health Survey (EDHS): a nationally representative household survey on healthcare. The EDHS employed a two-stage stratified cluster sampling technique. We computed standard women’s empowerment indices, following the Survey-based Women’s emPowERment index approach. A multilevel logistic regression model that accounted for cluster-level random effects was used to estimate the association between women’s empowerment and child growth faltering (stunting, wasting and underweight). Results Attitude to violence, social independence, and decision-making were the three domains of women’s empowerment that were associated with child growth faltering. One standard deviation increase in each domain of empowerment was associated with a reduction in the odds of stunting: attitude towards violence (AOR = 0.92; 95% CI 0.88–0.96; p p = 0.049), and decision-making (AOR = 0.93; 95% CI 0.87–0.99; p = 0.023). Similarly, each standard deviation increase in attitude towards violence (AOR = 0.93; 95% CI 0.89–0.98; p = 0.008), social independence (AOR = 0.91; 95% CI 0.86–0.97; p = 0.002), and decision-making (AOR = 0.92; 95% CI 0.86–0.99; p = 0.020) were associated with a decrease in the odds of having underweight child. Conclusions Ensuring women’s empowerment both in the household and in the community could have the potential to decrease stunting and underweight in a rapidly developing country like Ethiopia. Policymakers and health professionals need to consider women’s empowerment in this unique context to improve nutritional outcomes for children and alleviate growth faltering.

Aim: The epidemiological characteristics and modes of transmission of coronavirus disease 2019 (COVID-19) in children are not yet fully understood. In this study, it was aimed to evaluate clinical, laboratory, and radiological findings and treatment approaches in patients with negative and positive PCR tests among those with suspected COVID-19 retrospectively.Material and Methods: This study was conducted with 317 patients under 18 years of age, who received outpatient or inpatient treatment with a pre-diagnosis of COVID-19. All patients were assessed for clinical course, disease severity, comorbidity, demographic characteristics, laboratory and radiodiagnostic tests, treatment characteristics, and outcomes.Results: The PCR test was positive in 133 (42%) and negative in 184 (58%) of the patients with suspected COVID-19. There was a history of contact in 78 (58.6%) and 51 (27.7%) of the PCR-positive and negative patients, respectively (p, Amaç: Çocuklarda koronavirüs hastalığı 2019 (coronavirus disease 2019, COVID-19)'un epidemiyolojik özellikleri ve bulaşma yolları henüz tam olarak anlaşılamamıştır. Bu çalışmada, COVID-19 şüphesiyle takip edilen PCR testi negatif ve pozitif olan hastalarda klinik, laboratuvar ve radyolojik bulgular ve tedavi yaklaşımlarının geriye dönük olarak değerlendirilmesi amaçlanmıştır.Gereç ve Yöntemler: Bu çalışma, COVID-19 ön tanısı ile ayaktan veya yatarak tedavi gören 18 yaş altı 317 hasta ile yapılmıştır.

Context As the number of transgender (trans) people (including those who are binary and/or nonbinary identified) seeking gender-affirming hormone therapy rises, endocrinologists are increasingly asked to assist with interpretation of laboratory tests. Many common laboratory tests such as hemoglobin, iron studies, cardiac troponin, and creatinine are affected by sex steroids or body size. We seek to provide a summary of the impact of feminizing and masculinizing hormone therapy on common laboratory tests and an approach to interpretation. Cases Case scenarios discussed include 1) hemoglobin and hematocrit in a nonbinary person undergoing masculinizing hormone therapy; 2) estimation of glomerular filtration rate in a trans woman at risk of contrast-induced nephropathy; 3) prostate-specific antigen (PSA) in a trans woman; and 4) chest pain in a trans man with a cardiac troponin concentration between the reported male and female reference ranges. Conclusions The influence of exogenous gender-affirming hormone therapy on fat and muscle distribution and other physiological changes determines interpretation of laboratory tests that have sex-specific differences. In addition to affirmative practice to ensure a patient’s name, gender, and pronoun are used appropriately, we propose that once individuals have commenced gender-affirming hormone therapy, the reference range of the affirmed gender be reported (and specified by treating clinicians) except for PSA or cardiac troponin, which are dependent on organ size. While suggestions may be challenging to implement, they also represent an opportunity to lead best practice to improve the quality of care and experiences of healthcare for all trans people.

Yeni Coronavirus, SARS-CoV-2 olarak adlandirilmistir ve onceki insan koronaviruslerine kiyasla oldukca bulasici bir enfeksiyon ajanidir. Onceki her salginin kendine ozgu bir tehlikesi vardi. Yuksek bulasicilik potansiyeli, yeni koronavirusun birincil tehlikesidir. MERS-CoV enfeksiyonunun daha yuksek mortalite oranina sahip oldugu bilinmekle birlikte, SARS-CoV-2 kisa surede tum dunyadaki bircok insana yayilmistir. SARS-CoV-2 (SARS-CoV ve MERS gibi) cocuklari daha az enfekte eder ve cocuklarda yetiskinlere gore daha hafif klinik semptomlarla sonuclanir. Birincil patogenezi bilinmemektedir; cocuklarin bagisikliklarinda bulunan farklar, ajana maruz kalma olasiliginin daha az olmasi olabilir. Bununla birlikte, cogunlukla asemptomatik olmakla birlikte, cocuk populasyonu enfeksiyon yayilmasi icin potansiyel bir kaynaktir.

Objective Type 1 diabetes (T1D) is a disease characterized by severe insulin deficiency. In 2008 our group studied the prevalence of diabetes in adults between 20-80 years of age in Cyprus but data regarding this incidence in the pediatric population is lacking. The objective of this study was to report the incidence of T1D among permanent inhabitants aged 16 years or younger between 2001-2016 in Cyprus. Methods This study was a retrospective analysis. The patients were mainly evaluated and recorded at Dr. Burhan Nalbantoglu Hospital, Nicosia. Data was also reviewed from Famagusta Government Hospital, Kyrenia Government Hospital, Near East University Hospital and the Cyprus Turkish Diabetes Association. Results A total of 107 subjects were diagnosed as T1D between 2001 and 2016 in the pediatric age group. Forty-nine (45.7%) were girls and 58 (54.3%) were boys. Of these 38.7% were resident in Nicosia, 30.2% Famagusta, 12.3% Kyrenia, 9.4% Guzelyurt and 7.5% Iskele. The proportion of newly diagnosed T1D was highest among children aged 9-12 years (35.5%) followed by children aged 5-8 years (32.7%). Newly diagnosed T1D most frequently presented in March and April. The overall mean incidence rate was 11.1/100,000 between 2001 and 2016. The incidence rates were similar and comparable among the years. Conclusion This study is the first to analyze the incidence of T1D in Cyprus. Compared to other countries the incidence rate is intermediate. Our findings are similar to the incidence rates of T1D in South Cyprus and Turkey.

Many trans and gender diverse (TGD) people have gender identities that are not exclusively male or female but instead fall in-between or outside of the gender binary (non-binary). It remains unclear if and how those with non-binary gender identity differ from TGD individuals with binary identities. We aimed to understand the sociodemographic and mental health characteristics of people with non-binary identities compared with binary TGD identities. We performed a retrospective audit of new consultations for gender dysphoria between 2011 and 2016 in three clinical settings in Melbourne, Australia; (1) Equinox Clinic, an adult primary care clinic, (2) an adult endocrine specialist clinic, and (3) the Royal Children's Hospital, a child and adolescent specialist referral clinic. Age (grouped by decade), gender identity, sociodemographic, and mental health conditions were recorded. Of 895 TGD individuals, 128 (14.3%) had a non-binary gender. Proportions differed by clinical setting; 30.4% of people attending the adult primary care clinic, 7.4% attending the adult endocrine specialist clinic, and 8.0% attending the pediatric clinic identified as non-binary. A total of 29% of people in the 21-30-year-old age-group had a non-binary gender identity, higher than all other age-groups. Compared to TGD people with a binary gender identity, non-binary people had lower rates of gender-affirming interventions, and a higher prevalence of depression, anxiety, and illicit drug use. Tailoring clinical services to be inclusive of non-binary people and strategies to support mental health are required. Further research to better understand health needs and guide evidence-based gender-affirming interventions for non-binary people are needed.

Many of the considerable number of young people who identify as transgender or gender diverse do not conform to traditional binary notions of gender (male vs female), and instead have a non-binary gender identity. This narrative Review summarises literature related to the sociodemographic and clinical profiles of young people with a non-binary gender identity. Young people identifying as non-binary form a substantial minority of the general population. They experience lower levels of support and are at increased risk of experiencing abuse and victimisation than young people who are cisgender. Furthermore, compared with young people who are transgender and binary, people who identify as non-binary experience less access to trans-specific health care. Young people identifying as non-binary have poor mental health outcomes, with high rates of depression, anxiety, and suicidal ideation that were found to be similar if not higher than in those who are transgender and binary. This Review highlights that young people who identify as non-binary are highly vulnerable and likely to have important health-care needs.

The aim of this study was to summarize strategies to reduce postsurgical opioid prescribing at discharge.Current practices for the prescription of opioids at discharge after surgery are highly variable and often excessive. We conducted a systematic review to identify behavioral interventions designed to improve these practices.We searched MEDLINE, EMBASE, CINAHL, and PsycINFO until December 14, 2018 to identify studies of behavioral interventions designed to decrease opioid prescribing at discharge among adults undergoing surgery. Behavioral interventions were defined according to the Cochrane Effective Practice and Organisation of Care (EPOC) taxonomy. We assessed the risk of bias of included studies using criteria suggested by Cochrane EPOC and the Newcastle-Ottawa scale.Of 8048 citations that were screened, 24 studies were included in our review. Six types of behavioral interventions were identified: local consensus-based processes (18 studies), patient-mediated interventions (2 studies), clinical practice guidelines (1 study), educational meetings (1 study), interprofessional education (1 study), and clinician reminder (1 study). All but one study reported a statistically significant decrease in the amount of opioid prescribed at discharge after surgery, and only 2 studies reported evidence of increased pain intensity. Reductions in prescribed opioids ranged from 34.4 to 212.3 mg morphine equivalents. All studies were found to have medium-to-high risks of bias.We identified 6 types of behavioral strategies to decrease opioid prescription at discharge after surgery. Despite the risk of bias, almost all types of intervention seemed effective in reducing opioid prescriptions at discharge after surgery without negatively impacting pain control.

Introduction The pituitary gland serves as the center of the endocrine system. Stem cells are typically found in a specialized microenvironment of the tissue, called the niche, which regulates their maintenance, self-renewal, fate determination, and reaction to external influences. The aim of this study is to elucidate the role of stem cells in the initiation, invasion, and progression of pituitary adenomas. Materials and methods All specimens were collected between January 2007 and April 2015. Radiological classification (invasiveness) for all cases was performed according to the Wilson-Hardy classification system. Immunohistochemical staining was performed to all specimens for CD133, Oct4, Sox2 and nestin. Results The study included 48 patients. Of 48 patients, 17 (35.4%) were male and 31 (64.6%) were female. Mean age is 47.10±14.14 (17-86 yrs.). According to the Wilson-Hardy classification system, 27 (56.3%) were non-invasive adenomas. There was no statistical significance between the expression of pituitary stem cell markers (CD133, OCT4, SOX2, nestin) and invasiveness. Conclusion All stem cell markers are stained extensively in pituitary adenomas, except for SOX2 which was stained weakly. However, there is no effect of stem cells on invasiveness of pituitary adenomas because we cannot find a difference of the staining level between invasive and non-invasive adenomas. Nestin was stained extensively in functional adenomas, especially for GH, PRL, and gonadotropin secreting adenomas. SOX2 was stained extensively for ACTH-secreting adenomas.

Transgender, including gender diverse and non-binary people, henceforth referred to collectively as trans people, are a highly marginalised population with alarming rates of suicidal ideation, attempted suicide and self-harm. We aimed to understand the risk and protective factors of a lifetime history of attempted suicide in a community sample of Australian trans adults to guide better mental health support and suicide prevention strategies.Using a non-probability snowball sampling approach, a total of 928 trans adults completed a cross-sectional online survey between September 2017 and January 2018. The survey assessed demographic data, mental health morbidity, a lifetime history of intentional self-harm and attempted suicide, experiences of discrimination, experiences of assault, access to gender affirming healthcare and access to trans peer support groups. Logistic regression was used to examine the risk or protective effect of participant characteristics on the odds of suicide.Of 928 participants, 85% self-reported a lifetime diagnosis of depression, 63% reported previous self-harm, and 43% had attempted suicide. Higher odds of reporting a lifetime history of suicide attempts were found in people who were; unemployed (adjusted odds ratio (aOR) 1.55 (1.05, 2.29), p = 0.03), had a diagnosis of depression (aOR 3.70 (2.51, 5.45), p 0.001), desired gender affirming surgery in the future (aOR 1.73 (1.14, 2.61), p = 0.01), had experienced physical assault (aOR 2.01 (1.37, 2.95), p 0.001) or experienced institutional discrimination related to their trans status (aOR 1.59 (1.14, 2.23), p = 0.007).Suicidality is associated with barriers to gender affirming care, gender based victimisation and institutionalised cissexism. Interventions to increase social inclusion, reduce transphobia and enable timely access to gender affirming care, particularly surgical interventions, are potential areas of intervention.

To systematically review and synthesize the published literature regarding the education of general practitioners (GPs) and GPs in training (GPTs) in the use of ultrasonography.This systematic review was prospectively registered in PROSPERO, conducted according to the Cochrane recommendations. We combined studies identified in a previous systematic review with studies from an updated literature search using the same search string. We searched the following databases: MEDLINE via Pubmed, EMBASE via OVID, Cinahl via Ebsco, Web of Science and Cochrane Register of Controlled Trials using the words 'ultrasonography' and 'general practice'. Two reviewers independently screened articles, extracted data and assessed the quality of included papers according to the Down and Black quality assessment tool. Disagreements were resolved by involving a third reviewer.Thirty-three papers were included. Ultrasound training was described to include both theoretical and practical training sessions. Theoretical training was achieved through introductory e-learning and/or didactic lectures. Practical training included focussed hands-on training sessions, while some papers described additional longitudinal practical training through proctored scans during clinical work or through self-study practice with continuous feedback on recorded scans.There was a large variation in ultrasound training programs for GPs and GPTs, with an overall emphasis on focussed practical training. Few studies included a longitudinal learning process in the training program. However, diagnostic accuracy seemed to improve with hours of practical training, and studies including continuous feedback on scans conducted during clinical patient encounters showed superior results.Point-of-care ultrasonography is increasingly used by general practitioners (GPs) working in primary care as a diagnostic tool providing earlier and more precise diagnoses. However, ultrasonography is a user-dependent technology and obtaining competence requires both training and practice. Today, there is no consensus about which ultrasound training GPs should have before they start scanning patients in their clinics.

Hemangioblastomas (HBLs) are highly vascular and cystic benign neoplasms. They form very small part of intracranial tumours and are often localized in the posterior fossa. Although most of them are sporadic, a significant group is accompanied with von Hippel-Lindau (VHL) syndrome. This case report presents a 57-year-old woman treated with total resection using micro-surgical technique and was diagnosed as HBL based on histopathologic findings. Contrast-enhanced cranial MRI of the patient with the complaints of spasms in the right side of body showed a right paracentral mass that caused midline shift. In literature, the previously reported cases of supratentorial HBL unaccompanied with VHL syndrome were searched in PUBMED, compiled and presented. It should be borne in mind that rare HBLs manifesting with various neurological symptoms may occur in the supratentorial region, and may not accompany with VHL syndrome.

Background Meningiomas are heterogeneous, with differences in anatomical, histopathological, and clinical characteristics. Such spatial variability in meningioma biology is thought to result from differences in the expression of critical developmental regulators. We hypothesized that the variability in meningioma biology would follow gradients such as in embryology and tested a cohort of 366 meningiomas for histopathological and immunohistochemical gradients. Methods The medical records from 366 patients treated for meningiomas from 2003 to 2016 were retrospectively analyzed for age, gender, anatomical localization, recurrence-free survival, overall survival, histopathological diagnosis, and immunohistochemistry findings for 6 markers: epithelial membrane antigen (EMA), progesterone receptor (PR), CD34, S100, p53, and Ki-67 labeling index. Results EMA, PR, S100, p53, and CD34 were expressed in 94%, 73%, 49%, 26%, and 23% of the tumors, respectively. p53 expression correlated positively with Ki-67 and World Health Organization (WHO) grade (rτ = 0.31 and rτ = 0.4, respectively). PR positivity correlated inversely with S100, p53, Ki-67, and WHO grade (rτ = −0.19, rτ = −0.14, rτ = −0.15, and rτ = −0.16, respectively). All secretory meningiomas were positive for EMA and PR and negative for S100, and this pattern exhibited a rostrocaudal gradient. The overall proportion of EMA+PR+S100− cases was significantly lower in the cranial vault (30.3%) than in the skull base (45.89%; P = 0.021). The proportion of WHO grade II-III tumors was greater in cranial vault than in skull base meningiomas. Conclusions Unsupervised methods detected an association between the anatomical location and tumor biology in meningiomas. Unlike the categorical associations that former studies had indicated, the present study revealed a rostrocaudal gradient in both the cranial vault and the skull base, correlating with human developmental biology.

Background: The objective of this scoping review is to understand how treatment burden is experienced in elderly patients with cancer and what the most prevalent dimensions of treatment burden are among this population. According to one conceptual model, there are six dimensions of treatment burden, including financial, medication, administrative, time/travel, lifestyle, and healthcare. Methods: A scoping review methodology framework was used to collected data from EMBASE CINAHL (Cumulative Index to Nursing and Allied Health Literature), Medline/PubMed, Scopus, Web of Science, Embase, and Cochrane from 2000 to March 2020. Studies which focused on treatment burden among elderly patients with cancer (+65 years) were selected. Data were extracted using a standardized proforma. Results: The results identified 3319 total papers. Of these, 24 met the inclusion criteria and were included in the scoping review. A significant proportion of these studies was conducted in the United States (n = 10) using self-reported, cross-sectional data. Financial burden was the most prevalent dimension of treatment burden, with 11 studies focusing on the direct and indirect costs associated with cancer treatment. Other but less obvious aspects of treatment burden elderly patients experienced included the length of time taken to access and administer treatment and medication-related burdens. Conclusions: Emerging findings suggest that the financial aspects of cancer treatment are a significant burden for most elderly cancer patients. Personalized healthcare interventions targeting ways to reduce and screen for treatment burden, particularly those related to cost, are urgently needed.

Gender dysphoria describes the distress associated with having a gender identity that differs from one’s birth-assigned sex. To relieve this distress, transgender, and gender diverse (henceforth, trans) individuals commonly undergo medical transition involving hormonal treatments. Current hormonal treatment guidelines cater almost exclusively for those who wish to transition from male to female or vice versa. In contrast, there is a dearth of hormonal options for those trans individuals who identify as non-binary and seek an androgynous appearance that is neither overtly male nor female. Though prolonged puberty suppression with gonadotrophin releasing hormone agonists (GnRHa) could in theory be gender-affirming by preventing the development of unwanted secondary sex characteristics, this treatment option would be limited to pre- or peri-pubertal adolescents and likely have harmful effects. Here, we discuss the theoretical use of Selective Estrogen Receptor Modulators (SERMs) for non-binary people assigned male at birth (AMAB) who are seeking an androgynous appearance through partial feminization without breast growth. Given their unique range of pharmacodynamic effects, SERMs may represent a potential gender-affirming treatment for this population, but there is a lack of knowledge regarding their use and potentially adverse effects in this context.

Background Transgender, including gender diverse and non-binary people, henceforth referred to collectively as trans people, are a highly marginalised population with alarming rates of suicidal ideation, attempted suicide and self-harm. We aimed to understand the risk and protective factors of a lifetime history of attempted suicide in a community sample of Australian trans adults to guide better mental health support and suicide prevention strategies. Methods Using a non-probability snowball sampling approach, a total of 928 trans adults completed a cross-sectional online survey between September 2017 and January 2018. The survey assessed demographic data, mental health morbidity, a lifetime history of intentional self-harm and attempted suicide, experiences of discrimination, experiences of assault, access to gender affirming healthcare and access to trans peer support groups. Logistic regression was used to examine the risk or protective effect of participant characteristics on the odds of suicide. Results Of 928 participants, 73% self-reported a lifetime diagnosis of depression, 63% reported previous self-harm, and 43% had attempted suicide. Higher odds of reporting a lifetime history of suicide attempts were found in people who were; unemployed (adjusted odds ratio (aOR) 1.54 (1.04, 2.28), p = 0.03), had a diagnosis of depression (aOR 3.43 (2.16, 5.46), p p = 0.01), had experienced physical assault (aOR 2.00 (1.37, 2.93), p p = 0.007). Conclusion Suicidality is associated with desiring gender affirming surgery in the future, gender based victimisation and institutionalised cissexism. Interventions to increase social inclusion, reduce transphobia and enable access to gender affirming care, particularly surgical interventions, are potential areas of intervention.

Background and study aims Gastric cancer (GC) is usually preceded by premalignant gastric lesions (GPLs) such as gastric intestinal metaplasia (GIM). Information on risk factors associated with neoplastic progression of GIM are scarce. This study aimed to identify predictors for progression of GIM in areas with low GC incidence. Patients and methods The Progression and Regression of Precancerous Gastric Lesions (PROREGAL) study includes patients with GPL. Patients underwent at least two upper endoscopies with random biopsy sampling. Progression of GIM means an increase in severity according to OLGIM (operative link on gastric intestinal metaplasia) during follow-up (FU). Family history and lifestyle factors were determined through questionnaires. Serum Helicobacter pylori infection, pepsinogens (PG), gastrin-17 and GC-associated single nucleotide polymorphisms (SNPs) were determined. Cox regression was performed for risk analysis and a chi-squared test for analysis of single nucleotide polymorphisms. Results Three hundred and eight patients (median age at inclusion 61 years, interquartile range (IQR: 17; male 48.4 %; median FU 48 months, IQR: 24) were included. During FU, 116 patients (37.7 %) showed progression of IM and six patients (1.9 %) developed high-grade dysplasia or GC. The minor allele (C) on TLR4 (rs11536889) was inversely associated with progression of GIM (OR 0.6; 95 %CI 0.4–1.0). Family history (HR 1.5; 95 %CI 0.9–2.4) and smoking (HR 1.6; 95 %CI 0.9–2.7) showed trends towards progression of GIM. Alcohol use, body mass index, history of H. pylori infection, and serological markers were not associated with progression. Conclusions Family history and smoking appear to be related to an increased risk of GIM progression in low GC incidence countries. TLR4 (rs11536889) showed a significant inverse association, suggesting that genetic information may play a role in GIM progression.

Objective: The most prominent clinical finding in severe COVID-19 patients is endothelial damage. For these reasons, active administration of anticoagulants (such as heparin) is recommended to patients with severe COVID-19. The purpose of this study is to investigate the effects of different doses of low-molecular weight heparin (LMWH) on severe COVID-19 patients. Methods: This study was performed retrospectively in intensive care unit of a tertiary referral hospital. PCR (polymerase chain reaction) positive (+) patients were included in the study. Patients’ demographic data, length of stay in the hospital and intensive care unit, laboratory values (D-dimer, CRP, creatinine) on the last day of intensive care stay, mortality and invasive mechanical ventilator needs were recorded. Group O: consisted of patients not receiving anticoagulants, and Group 1 received a single daily dose of 40 mg enoxaparin sodium (equivalent to 4000 anti-Xa IU), and Group 2 received 2 daily doses of 1 mg/kg enoxaparin sodium. Results: A total of 191 patients were included in the study. 45% of the patients were female (n: 86), 55% were male. The mean age was found to be 67.6 ± 13.8. Patient numbers;group 0: 12, group 1: 90, group 2: 89. 7-day mortality was 50% in group 0, 22.2% in group 2, and 23.5% in group 3 (p value

Background: Intramedullary glial neoplasms affecting the entire spinal cord from the cervicomedullary junction to conus medullaris are termed holocord tumors. Pilocytic astrocytomas are relatively uncommon tumors forming holocord involvement. Hitherto 24 holocord astrocytoma cases were reported in the literature. Here, a case of an adult holocord pilocytic astrocytoma was presented. Case Description: A 29-year-old female patient presented with a subtotal resection. Histopathologic examination revealed pilocytic astrocytoma, World Health Organization grade 1, presenting holocord involvement. Magnetic resonance imaging showed a mass containing necrotic and cystic foci leading to an expansion along the entire spinal cord extending from C4 to conus medullaris. Conclusions: Reported holocord pilocytic astrocytomas in the relevant literature cases were reviewed. When evaluating magnetic resonance imaging scans of adult patients with various neurologic symptoms, i.e., weakness and fecal and urinary incontinence, pilocytic astrocytoma should be considered among differential diagnoses of intramedullary mass lesions. © 2019 Elsevier Inc.

Introduction: Glomerular hyperfiltration may lead to proteinuria and chronic kidney disease in unilateral multicystic dysplastic kidney (MCDK). We aimed to investigate the urine neutrophil-gelatinase-associated lipocalin (NGAL), netrin-1, hepcidin, and C-C motif chemokine ligand-2 (MCP-1/CCL-2) levels in patients with MCDK. Methods: Thirty-two patients and 25 controls were included. The urine hepcidin, netrin-1, NGAL, and MCP-1/CCL-2 levels were determined by ELISA. Results: The patients had higher serum creatinine (Cr) levels, urine albumin, and netrin-1/Cr ratio with lower GFR. There were positive correlations between urine protein/Cr, MCP-1/CCL-2/Cr, and netrin-1 with NGAL (r = 0.397, p = 0.031; r = 0.437, p = 0.041, r = 0.323, p = 0.042, respectively). Urine netrin-1/Cr was positively correlated with MCP-1/CCL-2/Cr (r = 0.356, p = 0.045). There were positive associations between the presence of proteinuria and netrin-1/Cr, MCP-1/CCL-2/Cr, and NGAL/Cr [Odds ratio (OR): 1.423, p = 0.037, OR: 1.553, p = 0.033, OR: 2.112, p = 0.027, respectively)]. ROC curve analysis showed that netrin-1/Cr, MCP-1/CCL-2/Cr, and NGAL/Cr had high predictive values for determining proteinuria p = 0.027, p = 0.041, p = 0.035, respectively). Urine hepcidin/Cr was negatively correlated with tubular phosphorus reabsorption and was positively correlated with urine NGAL/Cr (r = -0.418, p = 0.019; r = 0.682, p = 0.000; respectively). Conclusions: MCP-1/CCL-2 may play a role in the development of proteinuria in MCDK. Netrin-1 may be a protective factor against proteinuria-induced renal injury. Urine hepcidin/Cr may reflect proximal tubule damage in MCDK. Urine NGAL/Cr may be a predictor of tubule damage by proteinuria. Resumo Introdução: A hiperfiltração glomerular pode causar proteinúria e doença renal crônica no rim displásico multicístico unilateral (RDM). Nosso objetivo foi investigar os níveis de lipocalina associada à gelatinase neutrofílica na urina (NGAL), netrina-1, hepcidina e quimiocina C-C com ligante-2 (MCP-1/CCL-2) em pacientes com RDM. Métodos: Trinta e dois pacientes e 25 controles foram incluídos. Os níveis urinários de hepcidina, netrin-1, NGAL e MCP-1/CCL-2 foram determinados por ELISA. Resultados: Os pacientes apresentaram níveis séricos mais elevados de creatinina (Cr), albumina na urina e relação netrina-1/Cr com menor TFG. Houve correlação positiva entre proteína na urina/Cr, MCP-1/CCL-2/Cr e netrina-1 com NGAL (r = 0,397, p = 0,031; r = 0,437, p = 0,041, r = 0,323, p = 0,042, respectivamente). A netrina-1/Cr na urina foi correlacionada positivamente com MCP-1/CCL-2/Cr (r = 0,356, p = 0,045). Houve associações positivas entre a presença de proteinúria e netrina-1/Cr, MCP-1/CCL-2/Cr e NGAL/Cr [Odds ratio (OR): 1,423, p = 0,037, OR: 1,553, p = 0,033, OR: 2,112, p = 0,027, respectivamente) ]. A análise da curva ROC mostrou que netrina-1/Cr, MCP-1/CCL-2/Cr e NGAL/Cr apresentaram altos valores preditivos para determinar a proteinúria p = 0,027, p = 0,041, p = 0,035, respectivamente). A hepcidina/Cr na urina foi correlacionada negativamente com a reabsorção tubular de fósforo e positivamente com a NGAL/Cr na urina (r = -0,418, p = 0,019; r = 0,682, p = 0,000; respectivamente). Conclusões: MCP-1/CCL-2 pode ter participação no desenvolvimento de proteinúria no RDM. A Netrina-1 pode ser um fator protetor contra lesão renal induzida por proteinúria. Hepcidina/Cr na urina pode refletir danos em túbulos proximais no RDM. O valor de NGAL/Cr urinário pode ser um preditor de danos nos túbulos por proteinúria.

Background and Purpose: Scedosporium apiospermum complex as a ubiquitous environmental mold is increasingly reported to cause an invasive fungal infection in immunosuppressive hosts. Herein, we present the case of an immunosuppressive 54-year-old man who developed S. apiospermum complex lung infection and pulmonary adenocarcinoma. Case report: The patient had some complaints of dyspnea and cough during a neutropenic episode. The computed tomography (CT) scan of the patient revealed pleural effusion. After culturing the pleural fluid sample, the fungus was identified by microscopic examination and ITS sequencing. In addition, antifungal susceptibility testing was performed using the M38-A2 microdilution method. The minimum inhibitory concentrations of amphotericin B, voriconazole, posaconazole, and caspofungin were obtained as > 64, 0.06, 0.06, and 0.03 μg/mL, respectively. Voriconazole (administered in two doses of 6 mg/kg and a maximum of 250 mg) was preferred for treatment. The patient received antifungal treatment for 2 months; however, he was lost to follow-up. Conclusion: Scedosporium apiospermum complex should be considered a cause of systemic fungal infections in neutropenic patients. Furthermore, the determination of the in vitro antifungal susceptibilities of clinical strains may contribute to the development of therapeutic approaches.

Context The relationship between the endocrine system and autoimmunity has been recognized for a long time and one of the best examples of autoimmune endocrine disease is autoimmune hypophysitis. A better understanding of autoimmune mechanisms and radiological, biochemical, and immunological developments has given rise to the definition of new autoimmune disorders including autoimmunity-related hypothalamic–pituitary disorders. However, whether hypothalamitis may occur as a distinct entity is still a matter of debate. Evidence Acquisition Here we describe a 35-year-old woman with growing suprasellar mass, partial empty sella, central diabetes insipidus, hypopituitarism, and hyperprolactinemia. Evidence Synthesis Histopathologic examination of surgically removed suprasellar mass revealed lymphocytic infiltrate suggestive of an autoimmune disease with hypothalamic involvement. The presence of antihypothalamus antibodies to arginine vasopressin (AVP)-secreting cells (AVPcAb) at high titers and the absence of antipituitary antibodies suggested the diagnosis of isolated hypothalamitis. Some similar conditions have sometimes been reported in the literature but the simultaneous double finding of lymphocytic infiltrate and the presence of AVPcAb so far has never been reported. Conclusions We think that the hypothalamitis can be considered a new isolated autoimmune disease affecting the hypothalamus while the lymphocytic infundibuloneurohypophysitis can be a consequence of hypothalamitis with subsequent autoimmune involvement of the pituitary. To our knowledge this is the first observation of autoimmune hypothalamic involvement with central diabetes insipidus, partial empty sella, antihypothalamic antibodies and hypopituitarism.

Amaç: Çocukluk çağı viral hepatitlerin en sık nedeni Hepatit A virüsüdür (HAV). Tanısı anti HAV Ig M ile konmaktadır. Hastalığı geçiren veya Hepatit A aşısı yapılan kişilerde ise anti HAV Ig G düzeyi yükselmektedir. Bu çalışma ile hastaların HAV serolojisini araştırmayı ve Hepatit A aşısı tamamlanan çocukların HAV seroprevelansını ortaya koymayı amaçladık. Gereç ve Yöntemler: Çalışmaya Ocak 2016-Aralık 2018 tarihleri arasında HAV seroloji testleri değerlendirilen, 0-18 yaş çocuklar dahil edildi. Anti HAV Ig G ve anti HAV Ig M düzeylerinin yaşlara ve aşı uygulamalarına göre değişimleri retrospektif olarak incelendi. Bulgular: Çalışmaya 409 (%53,7) erkek ve 353 (%46,3) kadın olacak şekilde toplam 762 çocuk alındı. Genel yaş ortalaması 7,56±5,27 idi. Çocukların 422’sinde (%55,4) Anti HAV Ig G pozitif saptanırken, 340’ında (%44,6) negatif saptandı. Sadece 4 hastada Anti HAV Ig M pozitif saptandı. Aşılanan çocukların (%38,3) %88,4’ünde Anti HAV Ig G pozitifliği görüldü. Sonuç: Verilerimize göre aşısı olmayan çocukların günümüzde dahi Hepatit A hastalığına yakalanma ihtimalleri bulunmaktadır. Bu riski azaltmak için stratejiler geliştirmeli, aşı hakkında ailelerin farkındalıkları sağlanmalı, aşısı olmayan veya Hepatit A enfeksiyonu geçirmeyen kişilerde sağlanacak yüksek aşılanma oranları ile toplum içinde yeterli düzeyde Anti HAV Ig G pozitifliği yüzdesine ulaşılması gerekmektedir.

Mutations in isocitrate dehydrogenase genes IDH1 and IDH2 are frequently found in diffuse and anaplastic astrocytic and oligodendroglial tumours as well as in secondary glioblastomas. As IDH is a very important prognostic, diagnostic and therapeutic biomarker for glioma, it is of paramount importance to determine its mutational status. The haematoxylin and eosin (H&E) staining is a valuable tool in precision oncology as it guides histopathology-based diagnosis and proceeding patient’s treatment. However, H&E staining alone does not determine the IDH mutational status of a tumour. Deep learning methods applied to MRI data have been demonstrated to be a useful tool in IDH status prediction, however the effectiveness of deep learning on H&E slides in the clinical setting has not been investigated so far. Furthermore, the performance of deep learning methods in medical imaging has been practically limited by small sample sizes currently available. Here we propose a data augmentation method based on the Generative Adversarial Networks (GAN) deep learning methodology, to improve the prediction performance of IDH mutational status using H&E slides. The H&E slides were acquired from 266 grade II-IV glioma patients from a mixture of public and private databases, including 130 IDH-wildtype and 136 IDH-mutant patients. A baseline deep learning model without data augmentation achieved an accuracy of 0.794 (AUC = 0.920). With GAN-based data augmentation, the accuracy of the IDH mutational status prediction was improved to 0.853 (AUC = 0.927) when the 3,000 GAN generated training samples were added to the original training set (24,000 samples). By integrating also patients’ age into the model, the accuracy improved further to 0.882 (AUC = 0.931). Our findings show that deep learning methodology, enhanced by GAN data augmentation, can support physicians in gliomas’ IDH status prediction.

Overprescribing of opioids to patients following surgery is a public health concern, as unused pills may be diverted and contribute to opioid misuse and dependence. The objectives of this study were to determine current opioid-prescribing patterns for common surgical procedures, factors that affect surgeons’ prescribing behaviour and their perceived ability to manage patients with opioid use disorder.Survey participants included all consultant and trainee surgeons at the University of Toronto. The survey, which was administered electronically, included 52 multiple-choice, rank-order and open-text questions eliciting information on current prescribing patterns, prescribing of adjunct pain medications, and education and other factors related to opioid prescribing. Staff surgeons were also asked about how they manage patients with a suspected opioid issue.Eighty surgical trainees and 40 staff surgeons responded to the survey (response rate 32%). Five staff surgeons (12%) felt adequately educated to prescribe pain medications (including opioids) at discharge. Staff surgeons prescribed Tylenol 3 more frequently than other opioids. Twenty (51%) of 39 staff surgeons reported that they sought further help for their patients when an opioid use disorder was suspected.Our results support existing studies showing a large degree of variability in postoperative opioid prescribing. Institutional guidelines have been shown to be effective in curbing excessive opioid prescribing without increasing unnecessary emergency department visits for uncontrolled pain. Thus, there is an opportunity to develop institutional guidelines to educate surgical teams in the prescribing of opioids and about services available for patients with a substance use disorder.La surprescription d’opioïdes aux patients après une chirurgie représente un problème de santé publique car il y a un risque que les comprimés inutilisés soient détournés et utilisés à mauvais escient, voire qu’ils causent la dépendance. Cette étude avait pour objectif d’identifier les modes actuels de prescription des opioïdes pour les chirurgies courantes, les facteurs qui influent sur les habitudes de prescription des chirurgiens et leur capacité perçue à prendre en charge les cas de mésusage des opioïdes.Les participants au sondage étaient tous les chirurgiens en poste et en formation à l’Université de Toronto. Ce sondage administré par voie électronique comprenait 52 questions (choix multiples, échelles ordinales et ouvertes) qui visaient à recueillir des renseignements sur les modes actuels de prescription, la prescription d’analgésiques d’appoint, l’enseignement au patient et autres éléments relatifs à la prescription des opioïdes. Les chirurgiens en poste ont aussi été interrogés sur leur gestion des cas présumés de mésusage des opioïdes.Quatre-vingt chirurgiens en formation et 40 chirurgiens en poste ont répondu au sondage (taux de réponse, 32 %). Cinq chirurgiens en poste (12 %) se sont estimés adéquatement renseignés sur la façon de prescrire les analgésiques, (y compris les opioïdes) au moment du congé. Les chirurgiens en poste prescrivaient Tylenol 3 fois plus souvent que d’autres opioïdes. Vingt (51 %) chirurgiens en poste sur 39 ont dit consulter s’ils avaient besoin d’aide pour la prise en charge de patients soupçonnés de présenter un problème de mésusage des opioïdes.Nos résultats viennent étayer les conclusions d’études existantes selon lesquelles les modes de prescription des opioïdes en postopératoire varient grandement. Il a été démontré que l’adoption de lignes directrices institutionnelles permet de limiter efficacement la surprescription des opioïdes sans accroître indument le nombre de consultations aux urgences pour douleur non maîtrisée. Il y a donc là une possibilité d’adopter à plus grande échelle les lignes directrices institutionnelles pour sensibiliser les équipes chirurgicales à l’utilisation judicieuse des opioïdes et à l’existence des services à l’intention des patients qui présentent un problème de mésusage.
