RESUMO

BACKGROUND: We aimed to investigate the factors associated with neurological manifestations of post-coronavirus disease 2019 (COVID-19) conditions. METHODS: We retrospectively collected data from 440 patients who visited our post-COVID-19 clinic more than 4 weeks after severe acute respiratory syndrome coronavirus 2 infection. We analyzed the prevalence of different neurological symptoms (brain fog, memory impairment, headache, and dizziness) and assessed the associated factors. RESULTS: Brain fog was the most common symptom, observed in 170 patients (38.6%), followed by headaches (n = 137, 31.1%), dizziness (n = 128, 29%), and memory impairment (n = 104, 23.6%). Brain fog was associated with hyposmia or hypogeusia (odds ratio [OR], 2.54; P < 0.001), Fatigue Severity Scale (FSS) (OR, 1.06; P < 0.001), and Hospital Anxiety and Depression Scale-Anxiety (OR, 1.09; P = 0.037). Memory impairment was associated with sleep problems (OR, 2.83; P < 0.001), FSS (OR, 1.05; P < 0.001), and age (OR, 1.02; P = 0.015). Headache was associated with sleep problems (OR, 2.28; P = 0.001), sex (OR, 1.68; P = 0.042), and FSS (OR, 1.04; P < 0.001). Dizziness was associated with sleep problems (OR, 2.88; P < 0.001), and FSS (OR, 1.04; P < 0.001). The incidence of brain fog (P < 0.001), memory impairment (P < 0.001), dizziness (P = 0.007), and headache (P = 0.045) accompanied by hyposmia and hypogeusia was higher in patients with the aforementioned symptoms than in those without. CONCLUSION: This study suggests that there is a relationship between neurological symptoms and other clinical factors, such as fatigue, depression, anxiety, hyposmia, and hypogeusia.

RESUMO

BACKGROUND: We aim to compare the clinical characteristics and subjectively reported symptoms of the acute coronavirus disease (COVID) phase and those of the post-acute COVID phase to examine varying factors that affect the number of persistent symptoms and their categories. METHODS: We categorized 1,122 patients who visited the post coronavirus disease 2019 (COVID-19) clinic into two groups: "acute group" (< 4 weeks following diagnosis of COVID-19) and "post-acute group" (> 4 weeks following diagnosis of COVID-19). We statistically compared clinical characteristics between the two groups and determined which factors are associated with the number of persistent symptoms and their categories. RESULTS: The persistent symptoms of post COVID-19 conditions were classified into three categories as follows: Category A (the prevalence of symptoms is higher in the acute-visit group than in the post-acute-visit group), Category B (the prevalence of symptoms is not different between the two groups) and Category C (the prevalence of symptoms is higher in the post-acute-visit group than in the acute-visit group). Category A mainly included respiratory symptoms. Category B had generalized weakness, weight loss, cardiologic symptoms, hypogeusia, hyposmia, anxiety, and various gastrointestinal symptoms. Category C included fatigue, decreased attention, depression, blurred vision, hair loss, and sexual dysfunction. Anxiety, depression, fatigue and age were also associated with the number of symptoms and their categories, and anxiety is the most correlated factor (P < 0.001) among them. CONCLUSION: The persistent symptoms of post COVID-19 condition involve multi-organ and continue for four weeks or greater. Therefore, long-term observation and multidisciplinary interventions are essential for patients with post COVID-19 conditions.

RESUMO

BACKGROUND: ChAdOx1 and BNT162b2 vaccines are currently commonly used against coronavirus disease 2019 worldwide. Our study was designed to determine the serostatus and relative levels of anti-S and neutralizing antibodies in patients who were administered either ChAdOx1 or BNT162b2 vaccine. In addition, we investigated whether the antibody response to each vaccine differed according to sex and age. METHODS: Healthcare workers (HCWs) at a general hospital who were vaccinated with two doses of either ChAdOx1 or BNT162b2 were invited to participate in this prospective cohort study. Blood samples of HCWs vaccinated with both ChAdOx1 doses over a period of 12 weeks were collected at weeks 4 and 8 post first vaccination and 2 weeks post second vaccination. Blood samples of HCWs vaccinated with BNT162b2 were collected in the third week after the first dose, and the second dose was then administered on the same day; two weeks post second dose (5 weeks after the first dose), blood samples were collected to assess the antibody response. The titers of anti-S antibodies against the severe acute respiratory syndrome coronavirus 2 spike (S) protein receptor-binding domain and the neutralizing antibodies in the collected blood were evaluated. RESULTS: Of the 309 HCWs enrolled in the study, 205 received ChAdOx1 and 104 received BNT162b2. Blood samples from participants receiving either the ChAdOx1 or BNT162b2 vaccine exhibited substantial anti-S and neutralizing antibody seropositivity subsequent to the second dose. All participants (100%) from both vaccine groups were seropositive for anti-S antibody, while 98% (201/205) of ChAdOx1-vaccinated individuals and 100% (104/104) of BNT162b2-vaccinated individuals were seropositive for neutralizing antibodies. The median levels of anti-S and neutralizing antibodies were significantly higher in the BNT162b2-vaccinated group than the ChAdOx1-vaccinated group; in particular, anti-S antibody titers of 1,020 (interquartile range, 571.0-1,631.0) U/mL vs. 2,360 (1,243-2,500) U/mL, P < 0.05, were recorded for the ChAdOx1 and BNT162b2 groups, respectively, and neutralizing antibody titers of 85.0 (65.9-92.1%) vs. 95.8 (94.4-96.6%), P < 0.05, were recorded for the ChAdOx1 and BNT162b2 groups, respectively. In the ChAdOx1 vaccine group, the neutralizing antibody level was significantly higher in women than in men (85.7 [70.3-92.5%] vs. 77.7 [59.2-91.0%], P < 0.05); however, the neutralizing antibody titer in the BNT162b2 vaccine group did not vary between the two sexes (95.9 [95.2-96.6%] vs. 95.2 [93.5-96.3%], P = 0.200). Analysis of the correlation of antibody profiles with age revealed that the levels of anti-S antibodies and signal inhibition rate (SIR) of neutralizing antibodies decreased significantly with age. CONCLUSION: Both the ChAdOx1- and BNT162b2-vaccinated groups showed high seropositivity for anti-S and neutralizing antibodies. The SIR of neutralizing antibodies in the ChAdOx1 vaccine group was higher in women than in men. Enhanced antibody responses were observed in participants vaccinated with BNT162b2 compared to those vaccinated with the ChAdOx1 vaccine.

RESUMO

PURPOSE: This study was conducted to determine differences in adverse events associated with the first and second doses of the BNT162b2 coronavirus disease 2019 vaccine based on the age and sex of recipients. MATERIALS AND METHODS: An online survey on the post-vaccination adverse events of healthcare workers was conducted from March 2021 to April 2021. The differences in the types of adverse events, including severity, onset time, and duration of symptoms, and how the adverse events were dealt with by the patient were analyzed based on the age and sex. The profiles of adverse events were compared after the first and second vaccination doses. RESULTS: Among the 131 participants who participated in the online survey out of 208 vaccine recipients, 43 and 80 recipients of the BNT162b2 vaccine experienced adverse events after the first and second dose, respectively. No sex-related differences were observed in the profiles of adverse events in vaccinated recipients. The overall frequency of adverse events did not differ based on age after the first dose. After the second dose, the frequency of adverse events, including both local and systemic reactions was significantly higher in the younger age group than in the older age group. CONCLUSION: The BNT162b2 vaccine resulted in a higher frequency of adverse events after the second dose than after the first dose especially in the younger age group; however, no sex-related differences associated with these adverse events were observed.

RESUMO

The efficacy and safety of the BNT162b2 vaccine are known, but antibodies are expected to decrease over time after vaccination. We collected blood samples from 104 fully vaccinated health care workers at 3 and 5 weeks after first vaccination and 4 months after second vaccination. Antibody titers and neutralizing antibodies were measured. In our study, both antibody titers and neutralizing antibodies increased significantly at 5 weeks after first vaccination but decreased rapidly at 4 months after second vaccination. Additionally, the results showed a significant decrease regardless of gender or age. Further studies are needed to help determine the interval of SARS-CoV-2 vaccinations.

RESUMO

Parsonage-Turner syndrome is a rare neurological disease of varying etiology characterized by severe shoulder pain, muscle weakness, and atrophy. Mechanisms are unclear, but are thought to be genetic and immune-mediated reactions. Rarely, Parsonage-Turner syndrome occurs as a side effect of vaccination. A 20-year-old male who worked as a soldier visited the military hospital because of shoulder pain after vaccination against typhoid and was diagnosed with Parsonage-Turner syndrome based on electromyography and joint magnetic resonance imaging. Pain was controlled with a nerve block. Intravenous immunoglobulin was administered for improvement of neurologic symptoms. This case suggests that Parsonage-Turner syndrome should be considered as a side effect of vaccination. To the best of our knowledge, this is the first report of Parsonage-Turner syndrome following vaccination in Korea.

RESUMO

We report a case of a patient with scrub typhus who presented with diabetic ketoacidosis (DKA). The patient initially manifested with DKA, and was diagnosed with acute scrub typhus after evaluation the precipitating factors of DKA. No other complications of scrub typhus were noted. This case report suggests that acute scrub typhus should be considered as a precipitating factor of DKA, especially during the endemic season.

RESUMO

Most esophageal lipomas are discovered incidentally and are small and asymptomatic. However, large (>4 cm) lipomas may cause various symptoms, including dysphagia, regurgitation, or epigastric discomfort. We present a 45-year-old woman with intermittent sudden choking and globus pharyngeus. Upper gastrointestinal endoscopy and endoscopic ultrasound revealed an approximately 10.0×1.5 cm pedunculated subepithelial tumor in the upper esophagus, identified as the cause of her symptoms. A thoracic computed tomography scan revealed a fat attenuated longitudinal mass along the upper esophagus, suggestive of a lipoma. Endoscopic resection of the lesion was performed with a detachable snare to relieve her symptoms, and the pathologic findings were consistent with a lipoma.

RESUMO

Idiopathic cecal ulcer is a rare disease entity of unknown cause diagnosed by ruling out other known causes of cecal ulceration. The most common complication of an idiopathic cecal ulcer is bleeding; perforation, peritonitis, abscess, and stricture formation have been noted. The authors treated a 53-year-old woman who presented with fever and intermittent right upper quadrant abdominal pain. Multiple pyogenic liver abscess and a solitary cecal ulcer were diagnosed by radiologic, endoscopic, and pathologic examination, followed by laparoscopic cecectomy. After extensive study, we concluded that this patient's liver abscesses were a complication of the idiopathic cecal ulcer. Herein, we report a case of multiple pyogenic liver abscess caused by microperforation of idiopathic cecal ulcer.

RESUMO

Gastrointestinal tuberculosis that is not an unusual form of extrapulmonary tuberculosis and it is usually associated with immunocompromised condition that may present with clinical symptoms including fever, weight loss or pain. Terminal ileum and cecum are the common sites of involvement, but involvement of the stomach is rare. Furthermore, synchronous tuberculosis involving both the stomach and lower gastrointestinal tract has been reported in very few cases. Herein, we report a case of incidentally detected synchronous tuberculosis involving both the stomach and terminal ileum that was successfully treated by antituberculosis therapy in an asymptomatic immunocompetent patient.

RESUMO

Aerophagia is a disorder caused by abnormal accumulation of air in the gastrointestinal tract as a result of repetitive and frequent inflow of air through the mouth. For the diagnosis of this condition, it is difficult to objectively measure the air swallowing. However, multichannel intraluminal impedance monitoring facilitates the differential diagnosis between normal air swallowing and pathologic aerophagia, and can aid in the determination of the frequency and amount of air swallowed. In this report, in addition to a literature review, we describe a case of 36-year-old man with abdominal distension who was diagnosed with aerophagia using esophageal impedance monitoring and was treated with clonazepam.
