A 38-year-old right-handed female with a past history of intermittent painful rash, dizzy spells, and chronic daily headaches as well as episodic migraines experienced an episode of transient involuntary pathological laughter, right arm weakness, and expressive dysphasia. She was found on MRI to have multiple strokes in multiple vascular distributions, including one in the head of the left caudate. A cardiac ECHO found an atrial myxoma, with extensive evaluation for other causes of stroke unrevealing. The differential diagnosis for pathological laughter in this patient is discussed. The most plausible cause in this patient is an infarct to the head of the left caudate nucleus caused by an embolus of the atrial myxoma.

Aim: A variety of manifestations in different organs could be associated with severe COVID-19; for example, ocular manifestations. Case report: A 52-year-old male complaining of sudden onset unilateral painless vision loss in the right eye for 1 month (started just 1 week after COVID-19 remission) came to the ophthalmology clinic. On further evaluations, he was diagnosed with anterior ischemic optic neuropathy (AION). Considering his past history and the result of evaluations, the hypothesis of association between AION and COVID-19 was proposed. Results & discussion: Ocular and neurologic manifestations of COVID-19 are more likely to happen in patients with more severe conditions. Complications occur secondary to two basic mechanisms including severe inflammatory response and hypercoagulable state. Conclusion: Our findings indicated that non-arteritic AION is another manifestation of microangiopathic/thrombotic events which may occur in the course of COVID-19.

Abstract Background Lately, the humanity has been being threatened by the coronavirus disease (COVID-19). The virus-related destructive motives can damage not only the lungs but also the brain, blood vessels, kidneys, and the heart. Case presentation A middle-aged female presented with jaundice post-COVID-19 pneumonia. The patient had past history of cholecystectomy 20 years ago. Both laboratory and imaging data revealed a picture of cholestasis with right lobe liver abscess. Despite drainage and culture-based antibiotics, no improvement ensued. Endoscopic retrograde cholangiopancreatography was done revealing mildly dilated common bile duct (CBD), multiple large stones, mildly dilated central biliary radicals, and an old overlooked stent inside the dilated CBD. Papillotomy and papilloplasty were undertaken followed by stones’ extraction with insertion of 2 plastic stents (10 cm× 10 f), and a flow of thick dark bile was inspected. The patient was finally improved and safely discharged. Conclusion Herein, we present the first case of long-retained quiescent biliary stent which was over-headed by a cholangitic abscess in the vicinity of COVID pneumonia.

Aneurysm of the extracranial carotid artery is a rare disease, mycotic pseudoaneurysms being even less common. They are a life-threatening complication of systemic infection and atherosclerosis. Immunocompromised people, including patients with HIV, uncontrolled diabetes melltus, those on immunosuppressants like high-dose steroids, and chemotherapy, are at a higher risk for development of mycotic pseudoaneurysms. Due to the high risk of potential complications like rupture and thromboembolic events, mycotic aneurysms always require surgical management. Early detection followed by restoration of blood flow is critical to minimize a fatal outcome. Here we report the case of a 52-year-old man with a past history of hypertension and dyslipidemia who presented with a pulsatile painful neck swelling. On evaluation, the patient was diagnosed to have Salmonella typhi bacteremia, HIV infection, and a mycotic aneurysm of the left common carotid artery.

AbstractCerebral vasculitis is a long-standing but flourishing and fadeless research topic. Infections are a frequent cause of cerebral vasculitis, vital to diagnose due to involvement of specific anti-infection treatments. A 65-year-old man visited the hospital for his neurological symptoms without obvious inducements. After admission, radiological examination and comprehensive conventional microbiological tests (CMTs) revealed suspected intracranial infectious vasculitis. Metagenomic next-generation sequencing (mNGS) and reverse transcription-polymerase chain reaction further confirmed that his cerebral vasculitis was caused by Talaromyces marneffei (T. marneffei) and Aspergillus niger (A. niger) co-infection. The patient’s final diagnosis changed from initial herpetic encephalitis, due to the past history of cephalosome and facial herpes and non-significant antiviral therapeutic effects, to fungal cerebral vasculitis. The patient was discharged after use of targeted antifungal therapies on day 18 of his admission, and his associated symptoms disappeared completely at follow-up 3 weeks later. We first illustrated the presence of uncommon cerebral vasculitis caused by T. marneffei and A. niger in a human immunodeficiency virus-positive patient. In clinically suspected patients with infectious cerebral vasculitis, mNGS should be performed to detect potential pathogens if CMTs may not provide useful pathogenic clues, highlighting the importance of mNGS in the diagnosis and treatment of infectious diseases.

Patients with systemic lupus erythematosus may occasionally develop renal pathology from causes unrelated to the underlying disease. We describe one such case. This 22-year-old lady, with past history of arthritis, presented with dyspnea and fever. She had clinical signs consistent with systemic lupus erythematosus. Echocardiogram revealed valvular regurgitation. Antibiotics were started for probable infective endocarditis. She developed acute kidney injury. This was initially attributed to lupus nephritis, but subsequently renal histopathology revealed acute interstitial nephritis. Renal functions normalized with oral prednisolone. This case highlights the fact that a broader differential diagnosis must always be considered even if the diagnosis is clear.

Background Domestic violence (DV) is a universal issue and an important public health priority. Establishing a DV Registry System (DVRS) can help to systematically integrate data from several sources and provide valid and reliable information on the scope and severity of harms. The main objective of this study was to develop, validate, and pilot-test a minimum datasheet for a DVRS to register DV victims in medical facilities. Materials and methods This study was conducted in two main phases. Phase one includes developing the datasheet for registration of DV in the DVRS. In phase two, the datasheet designed in the previous step was used in a pilot implementation of the DVRS for 12 months to find practical challenges. The preliminary datasheet was first developed using information on similar registry programs and guidelines of the World Health Organization (WHO) and then reviewed by four expert panels. Through a two-round Delphi technique, experts evaluated the instrument using the Content Validity Index (CVI) and Content Validity Ratio (CVR). The consistency of the responses was evaluated by test-retest analysis. Finally, two physicians in two forensic medical clinics registered the victims of physical and/or sexual violence perpetrated by a family member. Results Preliminary datasheet consisted of 31 items. In the first round of Delphi, fifteen items had good content validity (I-CVI and CVR) and were kept, and seven items were moved to the next round. Also, in the first round of Delphi, experts suggested adding three items, including history of the violence, custody of the child, and custody of the elderly. All items evaluated in the second round were kept due to good CVR and CVI scores. As a result of Test-retest correlation coefficients for self-reprted items, two items including perpetrator’s alcohol and drug use status were excluded (r(30) = +.43, and +.38, p< .01, two-tailed, respectively). Finally, 24 items were included in the datasheet including 15 items for individuals’ characteristics (victims’ characteristics and perpetrators’ characteristics), eight items for incidents’ characteristics, and one item for past history of violence experience. A total of 369 cases were registered from September 23, 2019, to July 21, 2020. The majority of the reported cases were female (82%) and were 19–40 years old. No physical and/or sexual violence was reported from rural areas, which calls upon researchers to explore how services for detecting and treating the victims can be made accessible to these areas. Conclusion DVRS can show trends in DV by age, sex, the context of the violence, and incidence characteristics at every point in time. This is particularly valuable in planning and prioritizing research areas and interventions for DV prevention. Additionally, DVRS can be linked to other disease registry programs which can contribute to continuity and coordination of care, and major research in the future. Although a DVRS can be a promising initiative in identifying the areas in need of urgent interventions, there is no guarantee for its proper implementation due to limited resources and other challenges.

Objective Urinary tract infection (UTI) is a significant issue in young febrile patients due to potential long-term complications. Early detection of UTI is crucial in pediatric emergency departments (PEDs). We developed a tool to predict UTIs in children.Methods Clinical data of patients <24 months of age with a fever and UTI or viral infection were extracted from the fever registry collected in two PEDs. Stepwise multivariate logistic regression was performed to establish predictors of identified eligible clinical variables for the derivation of the prediction model.Results A total of 1,351 patients were included in the analysis, 643 patients from A hospital (derivation set) and 708 patients from B hospital (validation set). In the derivation set, there were more girls and a lower incidence of a past history of UTI, older age, less fever without source, and more family members with upper respiratory symptoms in the viral infection group. The stepwise regression analysis identified sex (uncircumcised male), age (≤12 months), a past history of UTI, and family members with upper respiratory symptoms as significant variables.Conclusion Young febrile patients in the PED were more likely to have UTIs if they were uncircumcised boys, were younger than 12 months of age, had a past history of UTIs, or did not have families with respiratory infections. This clinical prediction model may help determine whether to perform urinalysis in the PED.

Intussusception is defined by Treves in 1899 as invagination of segment of bowel into adjacent segment usually proximal into distal. It’s a common cause of abdominal emergencies especially in children two years of age and younger. It accounts for 1 in 2000 infants and children and results in intestinal obstruction. Post-operative intussusception is one of the rare etiologies of intestinal obstruction that represents 0.01 to 0.25% after laparotomies and 5 -10% of all early postoperative intestinal obstructions. Our case is a ten years old female presented to the National Center for Pediatric Surgery; Gezira state; Sudan; February 2021 complaining of abdominal distention and constipation for 6 days. She had past history of acute appendicitis due to which she underwent emergency opened appendectomy. Her condition started one day after appendectomy. O/E : patient looks ill, febrile, not pale or jaundice; PR:140b/m; RR:25c/m; abdominal examination show: distended abdomen with full flanks, unhealed lanz incision with small amount of pus discharge; no dilated veins or visible peristalsis; hernia orifice were intact; lower abdomen was tense & tender; no palpable mass; DRE: rectum contains impacted hard stool. Emergency explorative laparotomy was done. Findings: Ileocecal intussusception, bowel was healthy and viable. Simple reduction was done. Conclusion and Recommendations: Post-operative intussusception usually associated with bowel ischemia and necrosis which is not consistent with our case. We highly recommended abdominal ultrasonography, CT scan; when there is a high index of suspicion.

We have analyzed the distribution of early-type galaxies (ETGs) in the effective surface intensity vs. effective radius (Ie−Re) plane and in the total luminosity vs. central stellar velocity dispersion (L−σ) diagram, with the aim of studying the physical variables that allow the transformation of one space-parameter into the other. We find that the classical Faber–Jackson relation L=L0σα, in which the parameters L0 and α are confined in a small range of possible values, is incompatible with the distribution observed in the Ie−Re plane. The two distributions become mutually consistent only if luminosity is not considered a pure proxy of mass but a variable tightly dependent on the past history of mass assembling and star formation and on the present evolutionary state of the stellar content of a galaxy. The solution comes by considering the L=L0′σβ law proposed by D’Onofrio et al. in 2020, in which both L0′ and β can vary considerably from galaxy to galaxy. We will also show that the data of the Illustris numerical simulation prove the physical foundation of the L=L0′σβ law and confirm the prediction of the Zone of Exclusion (ZoE) originating from the intersection of the virial law with the L=L0′σβ relation. The ZoE is the region in the Ie−Re and Re−Ms diagrams avoided by real galaxies, and the border of which marks the condition of ‘full’ virial equilibrium with no recent significant merger events and no undergoing star formation.
