High rates of thromboembolic events have been seen in cases of COVID-19. Here, we report a case of 23-year-old previously healthy female presented with left-sided abdominal pain associated with vomiting. The computed tomography scan showed multiple ill-defined wedge-shaped low attenuating areas of the spleen, suggesting splenic infarction. In the absence of other thromboembolic contributing factors, we believe this was a thromboembolic event in splenic circulation in relation to COVID-19 infection. Our case adds to the evidence of an arterial thrombotic event in a noncritical COVID-19 patient, emphasizing the importance of addressing thromboembolism diagnosis and management measures to avoid potentially deadly consequences.

AbstractThe main manifestations of novel coronavirus usually include fever and cough. Neurological manifestations have not been properly identified in children. A 65-day-old infant was hospitalized due to poor feeding, weakness, lethargy, and occasional cough. She suffered several seizures during her hospitalization. The brain computed tomography scan depicted a minor hemorrhage. Due to the exacerbation of her condition during hospital stay and the presence of respiratory symptoms in her parents, coronavirus disease was suspected. Reverse transcription–polymerase chain reaction (PCR) of coronavirus was positive for both: child and parents. In children with neurological manifestations such as lethargy, recurrent seizures, cerebral hemorrhage, and clinical evidence of respiratory symptoms in his/her relatives, PCR testing for coronavirus is recommended.

Background We performed a national population-based study examining the incidence of both venous and arterial thromboembolic events in patients hospitalized with inflammatory bowel disease over the past decade. Methods A retrospective cross-sectional analysis using the Nationwide Inpatient Sample Database was performed. Patients hospitalized with Crohn’s disease and ulcerative colitis were identified using ICD-9 codes. The incidence of clinically relevant venous thromboembolic events and arterial thromboembolic events including myocardial infarction, visceral ischemia, cerebrovascular accidents, and peripheral arterial events was examined. Results During the study period, 461,415 hospitalized inflammatory bowel disease patients were identified. Among these patients, 28,820 had a diagnosis of a thromboembolic event (overall prevalence of 6%). The incidence of thromboembolic events in patients with inflammatory bowel disease rose from 5.65% in 2000 to 7.17% by 2009. There were 18,270 (3.96%) patients who had an arterial thrombotic event, the most common being myocardial infarction (50%), followed by visceral ischemia (25%), and cerebrovascular incidents (22%). There were 11,083 (2.4%) patients identified to have had a venous thrombotic event, with the most common manifestation being deep vein thrombosis (77%), pulmonary embolism (32%), and portal vein thrombosis (3.9%). Conclusion An increasing incidence of thromboembolic event in patients with inflammatory bowel disease was observed over the past decade. Interestingly, there were more arterial thrombotic events in comparison to venous thrombotic events.

AbstractIntroduction:Hoarseness is common and can have a major impact on patients’ quality of life. We report a rare case of hoarseness secondary to haemodialysis.Case report:A 62-year-old man described developing transient hoarseness after haemodialysis sessions, which he underwent three times weekly. Fibre-optic nasendoscopy showed incomplete glottis closure due to bowing of the vocal folds. A computed tomography scan of the neck and thorax was unremarkable. Speech therapy was unhelpful. The renal physicians concluded that no change could be made to his dialysis regime. The patient subsequently underwent injection laryngoplasty with calcium hydroxylapatite, with marked improvement of his symptoms.Discussion:A literature search found one relevant article reporting that 60 per cent of patients suffered post-dialysis hoarseness and decreased vocal fold thickness. It is postulated that dialysis causes dehydration of Reinke's space, affecting vocal fold thickness and the patient's voice.Conclusion:Hoarseness caused by haemodialysis is uncharted territory. Further research is required to determine its prevalence and contributing factors.

Scrub typhus has a variety of clinical presentations ranging from asymptomatic to fever with chills, myalgias, hepatitis, gastric ulcerations and pancreatitis, all being attributed to disseminated vasculitis, with splenic infarction being a rare presentation. A 26-year man, a resident of north India, presented with an acute febrile illness and abdominal pain, computed tomography scan of the abdomen was suggestive of a splenic infarct. After ruling out other aetiology, a positive IgM (ELISA) for scrub typhus led to treatment with oral doxycycline, following which the patient was discharged symptom-free. Rarely can splenic infarction be attributable to scrub typhus; so far, five such cases have been reported in the published literature.

A tracheal diverticulum is a type of paratracheal air cyst and is usually an incidental finding after a computed tomography scan of the neck and thorax. With an incidence between 1% and 4% in adults, tracheal diverticula are rare entities that can be symptomatic in certain cases. We present a case of a COVID-19 positive patient who presented to our hospital and was diagnosed with multiple tracheal diverticula during his hospitalization.

Abstract Background We diagnosed a clinical case of pulmonary infection involving Mycobacterium tuberculosis and Tropheryma whipplei in a patient with acute respiratory distress syndrome. The diagnosis was assisted by metagenomic next-generation sequencing of bronchoalveolar lavage fluid. Case presentation A 44-year-old Han Chinese inmate was transferred to the emergency department because of dry cough, chest tightness, and shortness of breath. The patient’s body temperature rose to 39.3 °C following empirical cephalosporin treatment for 1 week. The blood CD4+/CD8+ ratio was 0.7, suggesting immunodeficiency. Routine microbiological tests were performed, and tuberculosis interferon gamma release assays were positive. Mycobacterium tuberculosis polymerase chain reaction was also positive. Chest computed tomography scan revealed miliary nodules and ground-glass opacifications, which were in accordance with tuberculosis. To fully examine the etiology, we performed routine laboratory tests and metagenomic sequencing, the results of which indicated the presence of Mycobacterium tuberculosis and Tropheryma whipplei. We administered anti-tuberculosis regimen in combination with trimethoprim/sulfamethoxazole. The patient recovered, with chest computed tomography scan showing absorption of lesions. Conclusions Compared with traditional diagnostic methods such as culture and serology, metagenomic next-generation sequencing has the advantage of detecting a wide array of microorganisms in a single test and therefore can be used for clinical diagnosis of rare pathogens and microbial coinfections. It is particularly useful for immunocompromised patients as they are more prone to infection by opportunistic microorganisms.

The human respiratory tract has a complex airflow pattern. If any obstruction is present in the airways, it will change the airflow pattern and deposit particles inside the airways. This is the concern of breath quality (inspired air), and it is decreasing due to the unplanned production of material goods. This is a primary cause of respiratory illness (asthma, cancer, etc.). Therefore, it is important to identify the flow characteristics in the human airways and airways with a glomus tumour with particle deposition. A numerical diagnosis is presented with an asymmetric unsteady-state light breathing condition (10 l/min). An in vitro human respiratory tract model has been reconstructed using computed tomography scan techniques and an artificial glomus tumour developed 2 cm above a carina on the posterior wall of the trachea. The transient flow characteristics are numerically simulated with a realizable (low Reynolds number) k–ɛ turbulence model. The flow disturbance is captured around the tumour, which influenced the upstream and downstream of the flow. The flow velocity pattern, wall shear stress and probable area of inflammation (hotspot) due to suspended particle deposition are determined, which may assist doctors more effectively in aerosol therapy and prosthetics of human airways illness.
