Introduction Data describing atrial fibrillation (AF) care in emergency centres (ECs) in sub-Saharan Africa is lacking. We sought to describe the prevalence and outcomes of AF in a Tanzanian EC. Methods In a prospective, observational study, adults presenting with chest pain or shortness of breath to a Tanzanian EC were enrolled from January through October 2019. Participants underwent electrocardiogram testing which were reviewed by two independent physician judges to determine presence of AF. Participants were asked about their medical history and medication use at enrollment, and a follow-up questionnaire was administered via telephone thirty days later to assess mortality, interim stroke, and medication use. Results Of 681 enrolled patients, 53 (7.8%) had AF. The mean age of participants with AF was 68.1, with a standard deviation (sd) of 21.1 years, and 23 of the 53 (43.4%) being male. On presentation, none of the participants found to have AF reported a previous history of AF. The median CHADS-VASC score among participants was 4 with an interquartile range (IQR) of 2-4. No participants were taking an anticoagulant at baseline. On index presentation, 49 (92.5%) participants with AF were hospitalised with 52 (98.1%) participants completing 30-day follow-up. 18 (34%) participants died, and 5 (9.6%) suffered a stroke. Of the surviving 31 participants with AF and a CHADS-VASC score ≥ 2, none were taking other anti-coagulants at 30 days. Compared to participants without AF, participants with AF were more likely to be hospitalised (OR 5.25, 95% CI 2.10-17.95, p, Highlights • In a Tanzanian emergency centre, atrial fibrillation was common but patient awareness of their condition was low • Use of anticoagulants among patients with atrial fibrillation was rare both before and after hospital presentation • Following hospital presentation, thirty-day mortality and stroke rates among patients with atrial fibrillation were high

Background This study aimed to evaluate the reliability and validity of the self-administered questionnaire for Korean radiation workers. Methods From May 24, 2016, to June 30, 2017, 20,608 participants completed the questionnaire, providing information on sociodemographics, lifestyle, work history and practices, medical radiation exposure, and medical history, which was linked to the National Dose Registry and the National Cancer Registry. The validity of the questionnaire was evaluated using the responses of 20,608 workers, and reliability was evaluated using the responses of 3043 workers who responded to the survey twice. Results Responses concerning demographic characteristics and lifestyle showed reliability with a moderate-to-high agreement (kappa: 0.43–0.99), whereas responses concerning occupation and medical radiation exposure had a wide range of agreement (kappa: 0.05–0.95), possibly owing to temporal variability during employment. Regarding validity, responses to the question about the first year of employment had an excellent agreement with the national registry (intraclass correlation coefficient = 0.9); however, responses on cancer history had a wide range of agreement (kappa: 0.22–0.85). Conclusion Although the reliability and validity of the questionnaire were not distinguished by demographic characteristics, they tended to be low among participants whose occupational radiation exposure was minimal. Overall, the information collected can be reliable for epidemiological studies; however, caution must be exercised when using information such as medical exposure and work practices, which are prone to temporal variability.

Background Reverse total shoulder arthroplasty (RTSA) has become an increasingly popular surgery for patients with rotator cuff arthropathy, unreconstructible proximal humeral fracture, and end-stage glenohumeral arthritis. The increased annual volume of RTSAs has resulted in more postoperative complications and revision rates between 3.3% and 10.1%. Postoperative infection is one of the most common complications requiring revision surgery after primary RTSA. This study assesses patient-specific risk factors for development of early infection after primary RTSA in a single high-volume shoulder arthroplasty institution. Methods From 2014 to 2019, 902 consecutive primary RTSAs were performed for surgical treatment of rotator cuff arthropathy, glenohumeral arthritis, inflammatory arthropathy, and/or dislocation. Excluding proximal humeral or scapula fractures, 756 cases met the inclusion criteria and had a minimum of 3-month follow-up. All surgeries were performed using the same surgical technique and received similar antibiotic prophylaxis. Age, patient demographics, medical history, smoking history, and prior ipsilateral shoulder treatment and/or surgery were recorded. Multivariable logistic regression analysis was used to determine risk factors associated with development of postoperative shoulder infection. Results Thirty-five patients did not meet minimum follow-up criteria and were lost to follow-up. Overall, of 721, 22 patients (3%) developed a postoperative ipsilateral shoulder infection. Previous nonarthroplasty surgery and history of rheumatoid arthritis were significantly associated with the development of postoperative shoulder infection. Amongst 196 patients who had previous nonarthroplasty shoulder surgery, there were 12 postoperative shoulder infections (6%) compared with those without previous shoulder surgery (10 of 525, 2%) (P = .003). Among 58 patients with rheumatoid arthritis, there were 5 postoperative shoulder infections (9%) compared with patients without rheumatoid arthritis (17 of 663, 3%) (P = .010). Patient age, gender, smoking status, history of diabetes mellitus, history of cancer/immunosuppression, and prior cortisone injection did not demonstrate significant associations with the development of postoperative infection. Conclusion Prior nonarthroplasty shoulder surgery and/or rheumatoid arthritis are independently associated with the development of postoperative infection after primary RTSA. Patients who demonstrate these risk factors should be appropriately evaluated and preoperatively counseled before undergoing primary RTSA. Strong consideration should be given to avoid minimally invasive nonarthroplasty surgery as a temporizing measure to delay definitive RTSA.

Myopericarditis following mRNA Covid-19 vaccination has recently been reported to health authorities in a lot of countries. They can occur in very rare cases after either the Moderna (mRNA-1273 - Spikevax) or Pfizer-BioNTech (BNT162b2 - Comirnaty) vaccination. Cases predominately occur in younger adult men within 14 days following the second dose. In this article, we present a 56-year-old man with no prior medical history, whit the exception of a mild Covid-19 infection 4 months earlier, who experienced an episode of acute epigastric pain, profuse sweating, tachycardia, hypotension 4 days after the first dose of BNT162b2 vaccine. Troponin I level was elevated. Chest X-ray, electrocardiogram, echocardiogram, coronary angiography didn't show significant abnormalities. Cardiac Magnetic Resonance showed a pattern of acute myocarditis. The condition appeared to be self-limited and the patient recovered without specific therapy. No report of acute myocarditis was observed in the BNT162b2 and mRNA-1273 trials and very rare cases, in comparison to given doses, have been reported to pharmacovigilance systems worldwide. Further surveillance and evaluation of this side effect are warranted to establish the correct balance of benefits and risks of Covid-19 mRNA vaccines, above all in children and younger people (categories with the higher reactogenicity and the lower risk of Covid-19 complications). At the present time the benefits of Covid-19 vaccination significantly exceed possible risks.

Acute bilateral internal carotid occlusion was a very rare disease with a very poor prognosis. Clinical case reports according to the literature showed that mechanical thrombectomy was the most optimal treatment. We reported a clinical case of successful treatment with simultaneous thrombectomy in both occluded carotid arteries. A 62-year-old woman was admitted at our hospital within three hours of stroke onset secondary to an acute simultaneously bilateral carotid artery occlusion. On admission, her NIHSS (National Institutes of Health Stroke Scale) was 32. Non-contrast computed tomography right after that showed hyperacute infarction lesions in both hemispheres with right inferior temporal and insular cortex (Alberta Stroke Program Early CT Score - ASPECTS 8) and left putamen (ASPECTS 9). Her medical history included paroxysmal atrial fibrillation, prior ischemic stroke, pacemaker due to sick sinus syndrome. Her pre-stroke modified Rankin Scale score was 0 that she was fully recovered from previous stroke 4 months ago thanks to successful thrombectomy of the right internal carotid arteries (ICA). This time, the patient underwent again the simultaneous bilateral mechanical thrombectomy of both occluded ICA. The complete recanalization achieved on both sides with recanalization level of TICI-3 (thrombolysis in cerebral infarction) only in 38 mins after the groin puncture. She showed dramatic recovery and was discharged on day 28 with a Rankin Scale score of 2. Mechanical thrombectomy on bilateral ICA performed simultaneously will helps shorten the reperfusion time compared to the alternative one and thus, provides a better prognosis in acute ischemic stroke.

Spontaneous pneumomediastinum (SPM), pneumothorax (PNX) and subcutaneous emphysema are rare complications of COVID-19 pneumonia. In this paper we describe 3 cases of COVID-19 pneumonia complicated by SPM with or without PNX. Patient 1 was a 56-year-old woman whose medical history was significant for chronic leukemia. She presented with typical clinical signs of COVID-19 pneumonia and after 2 weeks of hospitalization she developed SPM and subcutaneous emphysema. The management of pneumomediastinum (PNM) was conservative and follow-up computed tomography showed resolution of PNM. Patient 2 was a 67-year-old man presenting with fever, cough and dyspnea. Computed tomography pulmonary angiography was performed after 2 weeks of hospitalization and showed bilateral peripheral consolidations together with massive PNM and right-sided PNX. Thoracic drainage catheter was inserted in his right chest. Despite all supportive care, the patient succumbed to illness. Patient 3 was a 74-year-old man who was admitted to our hospital with COVID-19 pneumonia and spontaneous right-sided PNX. A thoracic drainage catheter was inserted immediately and then removed after ten days which has led to progression of subcutaneous emphysema, PNX and newly diagnosed PNM. Patient was carefully monitored for the next 2 weeks. Follow-up chest x-ray showed regression of PNM and PNX. SPM, PNX and subcutaneous emphysema are rare complications of COVID-19 pneumonia. Increased alveolar pressure and diffuse alveolar injury in severe COVID-19 pneumonia may make the alveoli more prone to rupturing which leads to gas dissemination along the peribronchovascular sheath to the mediastinum. Most cases of SPM and PNX resolve with conservative management.

Objective We report a case of diffuse large B-cell urethral lymphoma initial presenting with non-healing urethra ulcer. Case Report A 68-year-old woman presented with a non-healing urethral ulcer accompanied with vulvar pruritus, which failed to medical treatment. Her medical history was unremarkable, lacking fever, weight loss or unexplained fatigue. There were no enlarged lymph nodes or palpable liver or spleen upon physical examination. Pelvic examination revealed an ulcerative lesion arising from the posterior wall of the urethral meatus. Cystourethroscopy showed no bladder involvement. Surgical excision of the urethral ulcer was done and immunohistochemical report showed a diffuse large B-cell lymphoma. Bone marrow needle biopsy and computed tomography were done and the diagnosis of primary diffuse large B-cell urethral lymphoma stage IEA was made. She underwent six cycles of cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab and was free of disease for 51 months. Conclusion This report of urethral lymphoma was presented as a non-healing ulcer initially, which was totally different previous reports, presenting with bleeding, either vaginal or urinary, urinary frequency, dysuria, urine retention and self-perceived mass, suggesting that unhealed ulcer on the perineal area should be promptly evaluated and avoidance of unnecessary delayed therapy for possible curable disease.

The impact of different sociodemographic and clinical characteristics on the COVID-19-related morbidity and mortality rates have been studied extensively around the world; however, there is a dearth of data on the impact of different clinical and sociodemographic variables on the COVID-19-related outcomes in Saudi Arabia. This study aimed to identify those at high risk of worse clinical outcomes, such as hospitalization and longer length of stay (LOS) among young and middle-aged adults (18 to 55 years). In this questionnaire-based cross-sectional study, 706 patients with real-time polymerase chain reaction (RT-PCR) confirmed COVID-19 infection were interviewed. Patients’ demographic characteristics, dietary habits, medical history, and lifestyle choices were collected through phone interviews. Patients with chronic health conditions, such as diabetes and hypertension, reported a higher rate of hospitalization, ICU admission, oxygen-support needs, and a longer period of recovery and LOS. Multiple logistic regression showed that diabetes, hypertension, and pulmonary disease (e.g., asthma and chronic obstructive pulmonary disease (COPD)) were associated with a higher risk of hospitalization and longer LOS. Multiple logistic regression showed that symptoms of breathlessness, loss of smell and/or taste, diarrhea, and cough were associated with a longer recovery period. Similarly, breathlessness, vomiting, and diarrhea were associated with higher rates of hospitalization. The findings of this study confirm the similarity of the factors associated with worse clinical outcomes across the world. Future studies should use more robust designs to investigate the impact of different therapies on the COVID-19-related morbidity and mortality in Saudi Arabia.

Bloody nipple discharge in pediatric patients is rare and mostly associated with benign conditions.Despite the generally benign nature, a thorough investigation of the cause and treatment is required if a palpable lesion is present. Here, the author reports a case of bloody nipple discharge in an adolescent girl with no significant medical history. Breast ultrasound demonstrated a solid, oval-shaped, circumscribed mass in the left subareolar region that was categorized as category 4a according to the breast imaging reporting and data system (BI-RADS). An excisional biopsy and histological examination confirmed a diagnosis of intraductal papilloma. While intraductal papilloma is rare in the pediatric population, ultrasound evaluation and knowledge of characteristic findings are useful for noninvasive diagnostics and image-guided treatment planning.

Mesenteric lipomas are rare tumors, with fewer than 50 reported cases. A 42-year-old woman with no significant medical history was referred to our hospital for surgical removal of submucosal myoma and a left ovarian tumor that was diagnosed at a different clinic. Preoperative magnetic resonance imaging findings suggested a differential diagnosis of fibroma, Brenner's tumors, and mature teratomas; however, the intraoperative findings showed a sigmoidal mesenteric tumor adherent to the left ovary. Pathological examination revealed degenerated adipose tissue, and the patient was diagnosed with sigmoidal mesenteric lipoma. When a degenerated sigmoidal mesenteric lipoma is adherent to the ovary, it must be differentiated from an ovarian tumor.

Pfeiffer syndrome, affecting roughly 1 in 100,000 individuals is characterized by acrocephalosyndactyly – the premature closure of skull sutures (craniosynostosis). These acrocephalosyndactyly syndromes which are often sporadic de novo but also autosomal dominant in inheritance can be characterized by the fact that they often involve FGFR and TWIST genes. In the presented case, a 27-year old male level three trauma admission displayed skull abnormalities on physical examination that history taking confirmed was the result of pediatric surgically corrected Pfeiffer syndrome. Noncontrast brain CT as part of his trauma work-up revealed characteristic Pfeiffer syndrome imaging pattern of midface hypoplasia, nonvisualization of coronal and sagittal sutures, and a degree of obstructive hydrocephalus. Pfeiffer syndrome requires extensive pediatric surgery often with poor adult follow up. The case presented provides good visualization of characteristic skull abnormalities in a surgically corrected adult. By virtue of imaging an adult, this provides readers with a unique look at the long-term viability and the body's resulting physiological adaptations of the extensive mandatory pediatric surgery these patients undergo.

Background COVID-19 is a pacing pandemic that affected health systems, economy, and social life in the whole world. Currently, there is no treatment for it, but the world is in a race that yielded, in a relatively short time than usual, several approved, promising vaccines in the middle of a storm of debates because of the speed of their production and approval. Objective This study assessed the willingness of Middle Eastern Arab publics to receive COVID-19 vaccines and investigated the factors behind any reluctance to receive them. Methods A self-administered questionnaire was distributed through social media applications in four Arab countries (Jordan, Saudi Arabia, Lebanon, and Iraq). Participants’ demographics, medical history, their experience with COVID-19, and their willingness to receive the available vaccines were obtained and analyzed. Results A total of 2,925 completed forms were included. Only 25% of the participants were willing to receive a vaccine while 33% were hesitant. Iraqis were the most willing to receive it while Jordanians were the least (35% and 17% of each country, respectively). Interestingly, 60% of the acceptors were ready to pay for the vaccine if not covered by governments. It was also found that American vaccines were preffered by 50% of the acceptors. However, 30% of acceptors were unsure of which vaccine is the best and 11% stated that any vaccine is good. Social media were the major source of information about COVID-19 and its vaccines. Finally, predictors of acceptance of the vaccines included living in Saudi Arabia and Iraq, being unmarried, having monthly income > $1,000, holding a medical degree, having high fear from COVID-19, feeling of being at risk of getting infected with COVID-19, and previous reception of influenza vaccine, whereas predictors of refusal included female sex and previous infection with COVID-19. Conclusion Middle Eastern Arabs are less likely to accept receiving the COVID-19 vaccines compared with non-Arabs. Health authorities in these countries are advised to intensify their awareness-raising activities about the vaccines while ensuring fair distribution of them.

A 79-year-old woman with a newly detected oval circumscribed lump in subcutaneous location on mammography and ultrasound turned out to be a Schwannoma after ultrasound-guided core needle biopsy. A 72-year-old woman with breast cancer in medical history demonstrated a new axillary mass in follow up, initially regarded as a lymph node metastasis. Core needle biopsy did not lead to a sufficient diagnosis. Pathologic examination after intraoperative sampling revealed a Schwannoma. These 2 case reports illustrate the importance of diagnostic imaging and remind to include Schwannomas in the differential diagnosis of breast and axillary masses.

Syncope is a common emergency department (ED) chief complaint. Rarely, syncope can be the result of right ventricular outflow obstruction from an intracardiac tumor, such as an intracardiac extension of intravenous leiomyomatosis (IVL). Typically, this type of tumor is confined to the pelvic veins, but in very rare cases, it can extend through the inferior vena cava into the right atrium. Point-of-care ultrasound (POCUS) can be a crucial tool in the ED for identifying intracardiac tumors presenting as syncope and expediting clinical management. We present the case of a 39-year-old female with no prior medical history that presented to the ED having experienced dyspnea on exertion and two syncopal episodes prior to ED admission. POCUS use in the ED elucidated the presence of a right atrial mass and further imaging showed a mass on the patient's uterus. After surgical removal of a portion of the atrial mass, a subsequent biopsy revealed it had leiomyoma-like features; as such, the patient was diagnosed with IVL. This case illustrates the importance of using POCUS in the ED to help determine the etiology of syncope. Although intracardiac extensions of IVL are rare, it is important for emergency physicians to keep this diagnosis in the differential in patients with symptoms or risk factors suggestive of IVL with intracardiac extension.

Ecchordosis physaliphora is a rare congenital benign hamartomatous lesion originating from nodal cord remnants. This is histopathologically indistinguishable from chordoma, and hence imaging plays a key role in diagnosis. These lesions are hypointense on T1-weighted and hyperintense on T2-weighted images, and follow CSF signal. In contrast to chordoma, Ecchordosis Physaliphora does not demonstrate contrast enhancement. Here, we present a case of 32-year-old male with no prior medical history, who presented to an outside facility for chronic headache workup and incidentally detected indeterminate lytic defect in the bony clivus with a well demarcated smoothly corticated margin. Further assessment with MRI brain showed findings characteristic of Ecchordosis physaliphora, a benign congenital hamartomatous lesion originating from nodal cord remnants requiring no additional follow-up imaging or intervention.

Meningeal tuberculoma is one of the most serious sites of tuberculosis. Its incidence varies depending on the geographical area, rare in Western countries and frequent in developing countries where it represents 5% to 10% of intracranial masses. We report the case of a 21-year-old male patient with no particular medical history from Africa and living in Europe for more than a year, is hospitalized for an isolated inaugural, generalized, afebrile seizure in whom the scanner and cerebral magnetic resonance imaging (MRI) revealed a meningeal mass with significant glove finger edema suggesting a primary brain tumor. Surgical excision and anatomopathological analysis of the excisional piece allowed the diagnosis of tuberculoma. Meningeal tuberculoma is a source of diagnostic error because its clinical and radiological expression can mimic a brain tumor. This is an etiology that should not be ignored in the face of a meningeal mass in any subject coming from or living in a region with a high endemic tuberculosis.

Background: As America’s third highest opioid prescribers, orthopedic surgeons have contributed to the opioid abuse crisis. This study evaluated opioid use after primary total joint replacement. We hypothesized that patients who underwent total hip arthroplasty (THA) use fewer opioids than patients who underwent total knee arthroplasty (TKA) and that both groups use fewer opioids than prescribed. Methods: A prospective study of 110 patients undergoing primary THA or TKA by surgeons at an academic center during 2018 was performed. All were prescribed oxycodone 5 mg, 84 tablets, without refills. Demographics, medical history, and operative details were collected. Pain medication consumption and patient-reported outcomes were collected at 2 and 6 weeks postoperatively. Analysis of variance was performed on patient and surgical variables. Results: Sixty-one patients scheduled for THA and 49 for TKA were included. THA patients consumed significantly fewer opioids than TKA patients at 2 weeks (28.1 tablets vs 48.4, P = .0003) and 6 weeks (33.1 vs 59.3, P = .0004). Linear regression showed opioid use decreased with age at both time points (P = .0002). A preoperative mental health disorder was associated with higher usage at 2 weeks (58.3 vs 31.4, P < .0001) and 6 weeks (64.7 vs 39.2, P = .006). Higher consumption at 2 weeks was correlated with worse outcome scores at all time points. Conclusions: TKA patients required more pain medication than THA patients, and both groups received more opioids than necessary. In addition, younger patients and those with a preexisting mental health disorder required more pain medication. These data provide guidance on prescribing pain medication to help limit excess opioid distribution.

Purpose: To establish an appropriate clinical protocol for early photoscreening in 12-to-24-month-old children at pediatric well-baby clinics. Methods: This prospective study included a total of 277 children aged 12–24 months who visited a pediatric well-baby clinic. All participants underwent: 1) inquiry of medical history; 2) photoscreening with PlusoptiX A12; and 3) comprehensive ophthalmologic examinations. The optimal referral cut-off point for PlusoptiX was determined by receiver operating characteristic analyses. A high-risk subgroup was defined as having a birth weight

Highlights • Gallstone ileus is very infrequent and require high suspicion for preoperative diagnosis. • It must be suspected in an elderly female with bowel obstruction and a history of recurrent episodes of acute cholecystitis. • If during a cholecystectomy, cholecystoenteric fistula is found, it must be considered that Gallstone ileus could occur later. • Mainly, gallstones larger than 2.5 cm that passes through a cholecystoenteric fistula are which could cause gallstone ileus., Introduction and importance Gallstone ileus in cholecystectomized patients is very infrequent and when it happens shortly after surgery is even rarer. We report the case of a patient who presented Gallstone ileus few days after open cholecystectomy which has not been reported before in literature. Case presentation A 52-year-old male with a history of recent open cholecystectomy was referred to our center due to a presumable surgical complication. During his hospitalization while trying to restart the oral route he presented abdominal pain and nausea. He evolved toward a bowel obstruction. We suspected gallstone ileus based on medical history as well as preoperative image study. We confirmed the diagnostic using a Computed Tomography. Surgical management was performed and a large gallstone was extracted from the bowel. The patient progressed favorably and was discharged. He was asymptomatic during the follow-up. Clinical discussion Cholecystectomized patients who have been reported with Gallstone ileus demonstrate different pathophysiological mechanisms or extraordinary presentations. This case describes a unique presentation illustrating relevant aspects of this pathology such as showing that acute cholecystitis can be its clinical manifestation or that it could happen after a cholecystoenteric fistula is found during a cholecystectomy. Conclusion Gallstone ileus in cholecystectomized patients is very rare. Clinical suspicion remains the cornerstone of diagnosis.

Highlights • The prevalence of intestinal amoebiasis is lower in Tunisia compared to other regions in Africa. • The clinical diagnosis is challenging due to the absence of specific symptoms. • The main treatment of intestinal amoebiasis is metronidoazole for a period of 14 days. • The surgical procedure for amoebiasis colitis is only indicated in case of bowel perforation or necrosis., Amoebiasis is a parasitosis, mainly caused by Entamoeba histolytica (E. histolytica). It is a common disease in tropical and subtropical regions. E. histolytica possesses different mechanisms of pathogenicity, and might lead to the invasion and lysis of the intestinal epithelium. Outside of the high-risk regions, acute intestinal amoebiasis is a very rare condition, often leading to misdiagnosis and death, if not promptly treated. We discuss the cases of 18 and 43 year-old men without medical history, who presented to the emergency department complaining of acute abdominal pain along with fever. Following imaging features and clinical presentation, appendicitis and a complicated form of Crohn's disease were respectively suspected. Given the severity of the symptoms, an explorative laparotomy was performed showing in both cases an inflammatory aspect of the intestine. Histological examination concluded intestinal amoebiasis, a diagnosis that wasn’t suspected at first. The learning point of these cases is considering invasive intestinal amoebiasis in patients presenting with an acute abdominal syndrome, even with no history of traveling abroad or immunodeficiency.

Introduction and importance The differential diagnosis of a paediatric abdominal mass can be extensive, as it potentially involves multiple organs including gastrointestinal, genitourinary, endocrine, and gynaecological systems. Hence, a systematic approach to history taking and physical examination is needed to clinch the diagnosis. Specifically, the approach for assessing, investigating, and managing a ballotable left hypochondrial mass in a child can be challenging. Case presentation We report a 10-year-old Dusun girl presenting with left hypochondrial pain and noted a left hypochondrial mass on examination. This report highlights the role of clinical imaging during the pre-operative and post-operative phases. Clinical discussion Ultrasound and CT imaging was useful in determining that the tumor originated from the tail of the pancreas. The presence of a definite capsule with internal solid-cystic components helped narrowed the differential diagnosis to solid pseudopapillary neoplasm (SPN) of the pancreas. MR liver was useful to rule out liver metastasis in this child. Intervention and outcome The patient was scheduled for laparotomy and tumour excision at a regional paediatric centre. Successful excision of the tumor en-mass was performed and the child's subsequent recovery was uneventful. Conclusion Clinical imaging plays a critical role in the diagnosis and management of paediatric solid organ tumours. Other than renal origin, suspicion of pancreatic tail origin should be considered by clinicians when encountering a ballotable left abdominal mass., Highlights • A mass arising from the pancreatic tail can present as a ballotable mass. • Imaging findings for solid pseudopapillary neoplasm and differentials are presented. • The role of imaging in the management of solid pseudopapillary neoplasm is discussed.

Introduction Vogt-Koyanagi-Harada (VKH) syndrome is a systemic autoimmune disorder that targets tissues containing melanocytes such as the eye, inner ear, meninges and skin. Despite a common genetic susceptibility, the association between VKH syndrome and rheumatoid arthritis (RA) has been rarely reported. Aim of the work To report a rare case with RA who developed incomplete VKH syndrome. The case is described and a review of the literature on similar cases is presented. Case report A 26 year-old Tunisian woman, with a medical history of Hashimoto’s thyroiditis, was diagnosed on 2011 with seropositive and erosive RA treated with Leflunomide. She presented to the emergency department on June 2018 with bilateral blurred vision associated with photophobia, vomiting and severe headache that had gradually progressed over the preceding five days. Ophthalmological examinations showed typical findings of VKH syndrome. The patient received intravenous infusions of methylprednisolone at a daily dose of 1000 mg for 3 days that was followed orally with 2 mg/kg of prednisone equivalent. Given the lack of improvement in visual acuity after 3 weeks of treatment, azathioprine was added and VKH remission was achieved on September 2018 as confirmed on optical coherence tomography. However, the patient passed away on October 2018 due to infectious complications of the immunosuppressant agents. Conclusion Treatments and outcomes of VKH are variable. Pharmacological management of such an association between RA and VKH may be challenging, so care must be taken to balance treatment escalation with adverse events in patients at risk.

Objective: To evaluate the demographics, genotype, and clinical presentation of pediatric patients presenting with distal intestinal obstruction syndrome (DIOS), and factors associated with DIOS recurrence. Methods: Case series of ten patients (median age 13.2 years), followed-up in a reference center, retrospectively assessed. Data analyzed included age, gender, cystic fibrosis genotype, meconium ileus at birth, hydration status, pulmonary exacerbation, Pseudomonas aeruginosa colonization, pancreatic insufficiency (PI), body mass index (BMI) at the episodes, clinical manifestations of DIOS, imaging studies performed, acute management of DIOS, maintenance therapy, and recurrence on follow-up. Results: All patients had two positive sweat chloride tests, and nine of ten also had genotype study. The most common genotype identified was homozygosis for the delta F508 mutation. In seven cases, a previous history of meconium ileus was reported. All patients had pancreatic insufficiency. Diagnosis of DIOS was based on clinical and imaging findings. Of the total number of episodes, 85% were successfully managed with oral osmotic laxatives and/or rectal therapy (glycerin enema or saline irrigation). Recurrence was observed in five of ten patients. Conclusion: In this first report of pediatric DIOS in South America, the presence of two risk factors for DIOS occurrence was universal: pancreatic insufficiency and severe genotype. Medical history of meconium ileus at birth was present in most patients, as well as in the subgroup with DIOS recurrence. The diagnosis relied mainly on the clinical presentation and on abdominal imaging. The practices in the management of episodes varied, likely reflecting changes in the management of this syndrome throughout time. Resumo: Objetivo: Avaliar os dados demográficos, o genótipo e o quadro clínico de pacientes pediátricos que apresentam síndrome da obstrução intestinal distal (DIOS) e os fatores associados à recidiva da DIOS. Métodos: Casuística de 10 pacientes (média de 13,2 anos) monitorados em um centro de referência e avaliados de forma retroativa. Os dados analisados incluíram idade, sexo, genótipo da fibrose cística, íleo meconial no nascimento, estado de hidratação, exacerbação pulmonar, colonização por Pseudomonas aeruginosa, insuficiência pancreática (IP), IMC nos episódios, manifestações clínicas da DIOS, estudos de diagnóstico por imagem realizados, manejo agudo da DIOS, terapia de manutenção e recidiva no acompanhamento. Resultados: Todos os pacientes apresentaram dois exames de cloreto no suor positivos e 09/10 também apresentaram estudo do genótipo. O genótipo mais comum identificado foi a homozigose da mutação delta F508. Em sete casos foi mencionado um histórico de íleo meconial. Todos os pacientes apresentaram insuficiência pancreática. O diagnóstico da DIOS teve como base achados clínicos e de imagem; 85% do número total de episódios foram tratados com sucesso com laxantes osmóticos orais e/ou terapia retal (enema de glicerina ou irrigação salina). A recidiva foi observada em 5 de 10 pacientes. Conclusão: Neste primeiro relatório da DIOS pediátrica na América do Sul, a presença de dois fatores de risco na ocorrência da DIOS foi universal: insuficiência pancreática e genótipo associado a doença grave. O histórico de íleo meconial no nascimento esteve presente na maioria dos pacientes, bem como no subgrupo com recidiva da DIOS. O diagnóstico dependeu principalmente do quadro clínico e do diagnóstico por imagem abdominal. As práticas de manejo de episódios variaram, provavelmente refletiram as mudanças no tratamento dessa síndrome ao longo do tempo.

Introduction True non-traumatic radial artery aneurysms (RAAs) are extremely rare, and few cases have been described. The majority of RAAs are post-traumatic or iatrogenic pseudo-aneurysms following arterial cannulation. However, RAAs due to other causes have also been described. Here a rare case of true idiopathic distal RAA, which was managed by surgical resection and repair with interposition vein graft, is described. Report A 62 year old female with a known medical history of hypertension and hyperlipidaemia presented with left wrist swelling of one year duration, associated with a pulsatile lump that was increasing in size. Duplex ultrasound and computed tomography angiography revealed a distal RAA. She underwent open surgical resection and repair with interposition vein graft using the distal left cephalic vein. Histopathology of the specimen revealed an aneurysm with atherosclerosis. She recovered well post-operatively with no complications. Discussion True idiopathic RAAs are rare. Surgical treatment is almost always recommended in view of the risk of complications. A case of true idiopathic distal RAA is presented here, which was managed successfully by surgical resection and repair with interposition vein graft., Highlights • True radial artery aneurysms are extremely rare; most are post-traumatic or iatrogenic. • Options include observation, excision with ligation, primary repair or interposition graft. • Surgery is usually recommended due to risk of complications and has minimal morbidity.

Highlights • Head and tail Pancreatic Duct stone mimically bilateral staghorn renal stone is rare. • Bilateral lumbar pain same in renal and pancreatic process due to dermatomal distribution. • Similar radiologic appearance pancreatic head and tail due to same topography of kidney., Introduction Pancreatolithiasis is an uncommon disease and the diagnosis of pancreatic duct stones is challenging. The radiological findings of pancreatic duct stones may mimic other diseases, such as renal stones. Case presentation A 42-year-old male came with chief complaint of recurrent bilateral flank pain accompanied by fever which worsen 7 days before admission. The patient was diagnosed as gastritis and received analgesics in several hospitals. Ultrasonography and IVP examinations showed stones in both kidneys. CT-scan was not performed due to limitation in the hospital. Patient was diagnosed bilateral staghorn nephrolithiasis. The patient underwent bilateral bivalve nephrotomy for staghorn renal stone performed by urologist, but intraoperatively, no stones were found. The patient was then consulted intraoperatively to the digestive surgeon and get immediate median laparotomy. Intraoperatively, stones were palpated in the head and tail of the pancreas. The stones were evacuated. The symptoms were relieved, neither recurrence, nor pain, nor postoperative leakage was found. Patient was discharged uneventfully 4 days after the procedure and had no complaints in further follow-ups. Discussion The symptoms of pancreatolithiasis may overlap with nephrolithiasis and gastritis. The presented case was unique because from the history taking, clinical symptoms, USG, and IVP findings supported the diagnosis of nephrolithiasis, but intraoperative findings reveal pancreatic duct stones. Conclusion For patient diagnosed with renal calculi based on sonography and IVP findings, differential diagnosis of pancreatic stone should be considered especially if no underlying cause is detected. In such circumstances relying on IVP and sonographic findings alone can be misleading.

Highlights • Multisystem inflammatory syndrome in children affects young Chilean patients. • Gastrointestinal symptoms and altered inflammation parameters predominate. • Although intensive care was needed, favorable clinical outcomes were achieved. • Cases appeared in clusters in the most vulnerable areas of Santiago. • Clinical teams must be alert during the weeks after COVID-19 cases rise significantly., Objective To describe the clinical and epidemiological characteristics of hospitalized children with multisystem inflammatory syndrome in children (MIS-C) in Santiago, Chile. Methods This was an observational study of children with MIS-C (May 1 to June 24, 2020), in three pediatric hospitals in Santiago. Demographic characteristics and epidemiological data, medical history, laboratory tests, cardiology evaluations, treatment, and clinical outcomes were analyzed. Results Twenty-seven patients were admitted (median age 6, range 0–14 years). Sixteen of the 27 (59%) required intensive care unit admission; there were no deaths. Seventy-four percent had no comorbidities, and the median number of days of symptoms before admission was 4 (range 2–9 days). Gastrointestinal symptoms were the most frequent, and inflammatory markers were increased at admission. A recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was detected in 82% of cases. The severe group showed significantly lower hemoglobin and albumin levels, decreased platelet counts, and higher d-dimer during disease evolution. Echocardiography showed abnormalities (myocardial, pericardial, or coronary) in 12 patients (46%) during their hospital stay. Anti-inflammatory treatment (immunoglobulin and/or corticosteroids) was prescribed in 24 patients. MIS-C appeared in clusters weeks after the peak of SARS-CoV-2 cases, especially in the most vulnerable areas of Santiago. Conclusions This study describes the first series (n = 27) of children with MIS-C in a Latin American country, showing favorable clinical outcomes. Education and alerts are required for clinical teams to establish an early diagnosis and prompt treatment.

Highlights • Surgery is the Gold standard for GIST's treatment , but microscopic margins can be acceptable for borderline tumors • Multiple GISTs with NF1, multiples surgeries for multiples recurrences or multiples localization might be needed. • Need for furthermore study of this subpopulation of GIST’s and a precise molecular identification that could lead to a new era of adjuvant or neoadjuvant therapies., Introduction GIST’s are the most common mesenchymal tumor of the gastrointestinal tract, clinically and radiologically heterogeneous, only a histological study can confirm the diagnosis. The link between NF1 and GISTs have been established but not fully elucidated. Case presentation we report 02 cases of NF1 associated GIST, a 60 years old woman with multiples GISTs in the duodenum, proximal jejunum and in the colon presenting an iron deficiency anemia due to chronic bleeding, operated with R0 resection and a low risk of recurrences and a 41 year old male patient with acute abdominal pain with a giant abdominal mass mimicking a hydatid cyst with no relevant medical history, diagnosed at the same time for typical clinical NF1, CT scan showed the cystic mass but did not confirmed its origin, a complete resection of the mass with no capsule fraction was tricky but successful and the histopathology found a high risk of recurrences. The 2 patients received adjuvant imatinib therapy with recurrence free survival at 12 months follow up. Our cases represents a rare entity (multiples GISTs and cystic GIST) within a rarest population (NF1 associated GIST). Discussion the diagnosis of NF1 is based on typical clinical criterias but the GISTs are known to be the variable, symptomatic or silent, small size or giant. Imaging is based on CT scan with intravenous contrast studying the vascular pattern, the extra intestinal and metastasis localizations. MRI is no superior, but useful in the study of pelvic GISTs and liver metastasis. Histopathology is the only way to confirm the diagnosis with marker staining with CD117 and DOG-1. The emerging imatinib, sunitinib and regorafinib are used as neoadjuvant or adjuvant therapies in GISTs with high or moderate risk of recurrences. No consensual guidelines are yet established for the follow up as the recurrences are more frequent. Conclusion GIST’s association to NF1 is established, but the different aspects of the physiopathological, clinical and the treatment haven’t been established yet with no larger population to study. We believe that the understanding of the development of this type of tumors within the NF type 1 group would allow a better treatment and follow up and may be can lead to screening.

Highlights • There are few clinical reports about unusual presentation of tori palatinus associated a systemic disorder. • New technologies for surgical planning are become more sutiable for clinicians and oral amnd maxillofacial surgeons. • Surgical treatment is still the gold standard approach for treating exostoses., Introduction Torus palatinus (TP) is a slow growing maxillary exostosis, commonly found in the in the hard palate on either side of the median raphe of the palatine bone. Its aetiology is still unclear, but it has been attributed to genetic events and environmental agents, with a slight predilection for the female gender. Presentation of case The aim of this case report was to describe an unusual presentation of nodular TP in younger female patient, with medical history of hysterectomy when she was 25 years old. The TP manifested insidious progression that affected functional activities such as eating, swallowing and normal pronunciation. Furthermore, we describe our experience during pre-planning the surgery by using 3D-scan-printing, and the conservative surgical approach performed. Discussion/conclusion TP may be associated with epidemiological, environmental and systemic disorders of patients suffering from this condition. Conservative surgical removal continues to be the first choice treatment when the TP must be removed. Further studies are considered necessary to elucidate the etiological factors.

Highlights • Rare presentation of actinomycosis of the tongue makes it challenge. • Actinomycosis should be kept as a differential diagnosis in bewildering cases. • Histopathology consider as important diagnostic aids in challenged cases. • Varied clinical manifestations of the disease. • Treatment should implement in harmony according to each diseases solely., Introduction Rare presentation of tongue actinomycosis makes it challenge, less than 3% of all recorded cases of actinomycosis can be proved in the English literature. In this study we clarify the unexpected presence of actinomycosis wishing that it assist our practitioner colleagues in diagnosing such lesions perfectly. Case presentation Sixty five years old female was complaining from mass in the tongue submucosally since 1 year last with no history of fever, pain and trauma. It’s situated in the anterior third of the tongue, mild discomfort with percussion. Benign neoplasm was the clinical diagnosis. Decision was excisional biopsy. So patient underwent surgery under local anesthesia. Complete excision was done. Specimen sends for histopathological examination. Good healing process. Patient advice to keep on tetracycline capsule 250 mg for 1 month precautionary. Histopathological examination of the biopsy specimen diagnosis was mycetoma, with no malignancy. Discussion Clinically actinomycosis can be challenge too when it be silent not manifest as infection more over similarity to other pathological conditions at that time detailed patient history will be invaluable to exclude neoplastic pathology. Surgeons should pay attention to that prolonged antibiotic therapy is usually required is mandatory in some cases, and excellent prognosis confirmed. With better oral hygiene, availability of antibiotics, and advanced surgical techniques, the outcome, and mortality have improved. Conclusion Varied clinical manifestations of the disease are make achievement of clinical diagnosis of actinomycosis is difficult. Treatment should implement in harmony according to each diseases solely.

Introduction Cannabis is the most commonly used drug in the United States; however, the effects of cannabis use on male sexual function are poorly understood. Aim To characterize the contemporary landscape of cannabis use and to assess the associations between male sexual function and the frequency of use, the primary method of consumption, or cannabis chemovar (tetrahydrocannabinol or cannabidiol) among current users. Methods We surveyed adults who visited a single cannabis dispensary for baseline demographic information, medical history, cannabis use habits, and sexual function as assessed by the International Index of Erectile Function (IIEF). An IIEF-5 < 21 was considered erectile dysfunction. Main Outcome Measures The main outcome measure of the study was male sexual function via the IIEF domain scores. Results A total of 325 men completed the survey with a mean age of 46.7 years. 71.1% of the men were Caucasian and 52.6% were married. 13 men (4%) were never users; 29 men (8.9%) used 1–2 times/week; 51 men (15.7%) used 3–5 times/week, and 232 men (71.4%) used 6+ times/week. The average IIEF-5 score was 22.3 with 19.4% of the men having erectile dysfunction. In univariate analysis, men using cannabis more frequently had a higher overall IIEF (65.36 vs 60.52, P = .001), erectile domain (27.32 vs 25.74, P = .03), orgasm domain (9.08 vs 8.12, P < .001), intercourse satisfaction domain (12.42 vs 11.31, P = .006), and overall satisfaction domain (8.11 vs 7.05, P = .002). In multivariable analysis, compared to men who used cannabis 0 times/week, those who used 6 times/week had an increased overall IIEF (69.08 vs 64.64, P-value adjusted = 0.02), intercourse satisfaction domain (P-value adjusted = 0.04), and overall satisfaction domain (P-value adjusted = 0.02). The primary method of consumption (eg, smoking, edibles, etc.) and cannabinoid composition (eg, cannabidiol vs tetrahydrocannabinol dominant) were not associated with sexual function. Conclusion We report an association between the increased frequency of cannabis use and increased male sexual function. However, while the increased frequency of use was statistically significant with regard to the IIEF scores, the clinical significance of this is likely low, and selection bias may limit the generalizability of these findings. The method of consumption and cannabis chemovar were not associated with sexual function.

Purpose Traumatic brain injury (TBI) is one of the leading causes of disability and death in modern times, whose evaluation and prognosis prediction have been one of the most critical issues in TBI management. However, the existed models for the abovementioned purposes were defective to varying degrees. This study aims to establish an ideal brain injury state clinical prediction model (BISCPM). Methods This study was a retrospective design. The six-month outcomes of patients were selected as the end point event. BISCPM was established by using the split-sample technology, and externally validated via different tests of comparison between the observed and predicted six-month mortality in validating group. TBI patients admitted from July 2006 to June 2012 were recruited and randomly divided into establishing model group and validating model group. Twenty-one scoring indicators were included in BISCPM and divided into three parts, A, B, and C. Part A included movement, pupillary reflex and diameter, CT parameters, and secondary brain insult factors, etc. Part B was age and part C was medical history of the patients. The total score of part A, B and C was final score of BISCPM. Results Altogether 1156 TBI patients were included with 578 cases in each group. The score of BISCPM from validating group ranged from 2.75 to 31.94, averaging 13.64 ± 5.59. There was not statistical difference between observed and predicted mortality for validating group. The discrimination validation showed that the BISCPM is superior to international mission for prognosis and analysis of clinical trials (IMPACT) lab model. Conclusion BISCPM is an effective model for state evaluation and prognosis prediction of TBI patients. The use of BISCPM could be of great significance for decision-making in management of TBI.

Background: Increased coronary artery atherosclerosis in rheumatoid arthritis (RA) may cause significant mortality. Tumor necrosis factor (TNF) is a potent proinflammatory cytokine that has been involved in RA pathogenesis and atherosclerosis. Aim of the work: To determine the association between TNF-α rs1800629 polymorphism and carotid atherosclerosis in RA patients. Patients and methods: This study was carried out on 50 RA patients and 40 age and sex matched healthy control. All patients were subjected to full history taking, thorough clinical examination, and assessment of disease activity score (DAS28). Carotid artery intima–media thickness (IMT) was measured by Doppler ultrasonography. TNF-α −308A/G (rs1800629) polymorphism was assessed. Results: The mean age of patients was 41.2 ± 13.2 years with disease duration of 6.1 ± 4.5 years. The mean DAS28 was 4.1 ± 0.8 and Larsen score 2.1 ± 0.9. The mean IMT was significantly higher in patients (0.78 ± 0.47 mm) compared to the control (0.44 ± 0.16 mm) (p

Background: Physicians commonly judge whether a myocardial infarction (MI) is type 1 (thrombotic) vs type 2 (supply/demand mismatch) based on clinical information. Little is known about the accuracy of physicians’ clinical judgement in this regard. We aimed to determine the accuracy of physicians’ judgement in the classification of type 1 vs type 2 MI in perioperative and nonoperative settings. Methods: We performed an online survey using cases from the Optical Coherence Tomographic Imaging of Thrombus (OPTIMUS) Study, which investigated the prevalence of a culprit lesion thrombus based on intracoronary optical coherence tomography (OCT) in patients experiencing MI. Four MI cases, 2 perioperative and 2 nonoperative, were selected randomly, stratified by etiology. Physicians were provided with the patient’s medical history, laboratory parameters, and electrocardiograms. Physicians did not have access to intracoronary OCT results. The primary outcome was the accuracy of physicians' judgement of MI etiology, measured as raw agreement between physicians and intracoronary OCT findings. Fleiss’ kappa and Gwet’s AC1 were calculated to correct for chance. Results: The response rate was 57% (308 of 536). Respondents were 62% male; median age was 45 years (standard deviation ± 11); 45% had been in practice for > 15 years. Respondents’ overall accuracy for MI etiology was 60% (95% confidence interval [CI] 57%-63%), including 63% (95% CI 60%-68%) for nonoperative cases, and 56% (95% CI 52%-60%) for perioperative cases. Overall chance-corrected agreement was poor (kappa = 0.05), consistent across specialties and clinical scenarios. Conclusions: Physician accuracy in determining MI etiology based on clinical information is poor. Physicians should consider results from other testing, such as invasive coronary angiography, when determining MI etiology. Résumé: Contexte: Les médecins déterminent généralement s’ils sont en présence d’un infarctus du myocarde (IM) de type 1 (thrombotique) ou de type 2 (demande accrue ou apport réduit en oxygène) sur la base des renseignements cliniques. On en sait cependant très peu au sujet de la justesse du jugement clinique des médecins à cet égard. Nous avons donc cherché à déterminer si les médecins réussissent à distinguer correctement les IM de type 1 et de type 2 dans les contextes périopératoire et non opératoire. Méthodologie: Nous avons mené une enquête en ligne en utilisant les cas de l’étude OPTIMUS (Optical Coherence Tomographic Imaging of Thrombus), qui avait évalué la prévalence des lésions causant un thrombus au moyen de la tomographie par cohérence optique (TCO) endocoronaire chez les patients subissant un IM. Nous avons choisi au hasard quatre cas d’IM stratifiés en fonction de leur cause : deux cas en contexte périopératoire et deux cas en contexte non opératoire. Les médecins avaient accès aux antécédents médicaux, aux résultats des analyses de laboratoire et aux électrocardiogrammes des patients, mais pas aux résultats de la TCO endocoronaire. Le principal paramètre d’évaluation était la justesse du jugement du médecin concernant la cause de l’IM, mesurée en fonction de la concordance approximative entre le jugement du médecin et les observations à la TCO endocoronaire. Les coefficients de concordance kappa de Fleiss et AC1 de Gwet ont servi à corriger pour le hasard. Résultats: Le taux de réponse était de 57 % (308 sur 536). Des participants, 62 % étaient des hommes et 45 % exerçaient depuis plus de 15 ans; l’âge médian était de 45 ans (écart-type : ± 11). La justesse globale avec laquelle les répondants ont déterminé la cause des IM était de 60 % (intervalle de confiance [IC] à 95 % : 57-63 %) : 63 % (IC à 95 % : 60-68 %) dans le cas des IM en contexte non opératoire et 56 % (IC à 95 % : 52-60 %) dans le cas des IM en contexte périopératoire. La concordance globale corrigée pour le hasard était faible (kappa = 0,05) et demeurait constante, sans égard au domaine de spécialité ou au scénario clinique. Conclusions: La justesse du jugement des médecins évaluant la cause d’un IM en fonction des renseignements cliniques est faible. Les médecins devraient envisager de recourir à des tests additionnels, y compris la coronarographie invasive, avant de déterminer la cause d’un IM.
