RESUMO
BACKGROUND: Pneumothorax is a known sequela of coronavirus disease 2019 (COVID-19). However, the clinical features of pneumothorax associated with COVID-19 have not been fully elucidated. METHODS: Patients who developed pneumothorax within 6 months of being diagnosed with COVID-19 were retrospectively analysed at two institutions. We investigated the background factors, COVID-19 severity and treatment, timing of pneumothorax onset, treatment modalities, treatment duration, and prognosis of these patients. RESULTS: A total of 21 patients were diagnosed with pneumothorax within 6 months of COVID-19 diagnosis. The combined incidence rate of pneumothorax at two institutions was 0.89 %. The mean age of these patients was 72.5 years, and they were predominantly male (90.5 %), with a history of smoking (76.1 %). The most frequent comorbidity was hypertension, followed by type 2 diabetes mellitus, COPD, and malignancy. Approximately 76 % of the patients had moderate or severe disease requiring oxygenation. Moreover, 90.5 % of these patients were taking antiviral drugs; 52.4 %, immunosuppressant agents (baricitinib/tocilizumab); and 66.7 % were on dexamethasone. The median time to the onset of pneumothorax was 15.0 days, and 86 % of cases occurred within 1 month of COVID-19 diagnosis. Bilateral pneumothorax and pneumomediastinum were noted in one patient each. Chest drainage was performed in 71.4 % of the patients. The mean treatment duration for pneumothorax was 14.1 days, and the 30-day mortality rate was 28.6 %. CONCLUSION: Pneumothorax associated with COVID-19 was more common in patients with moderate or severe disease requiring oxygenation, and occurred within 1 month of COVID-19 diagnosis. Pneumothorax associated with COVID-19 is a serious complication with a high mortality rate and clinicians should pay attention to it.

Background: Molnupiravir is being widely used as a treatment for coronavirus disease 2019 (COVID-19); however, its acceptability and safety in older patients aged ≥ 80 years in real-world clinical practice is not well understood. Methods: We conducted a single-centre retrospective study and assessed the outcome of patients with COVID-19 treated with molnupiravir according to the following criteria: (A) discontinuation rate of molnupiravir; (B) type, frequency, and severity of adverse events; (C) all-cause mortality within 30 days of the diagnosis of COVID-19. Results: Forty-seven patients (46.1%) were aged ≥ 80 years (older patients) and 55 (53.9%) were aged < 80 years (younger patients). There were no significant differences in coexisting diseases and history of vaccination for COVID-19 between older and younger patients. Older patients were significantly more likely to have moderate disease (moderate 1 and 2) according to the Japanese Ministry of Health, Labour and Welfare classification than younger patients. During treatment, 8.5% of older patients and 1.8% of younger patients stopped taking molnupiravir, but the difference was not significant. Adverse events were observed in 39/102 (38.2%) patients. The most common adverse events were diarrhoea (9.8%), exacerbation of coexisting diseases (6.9%), bone marrow suppression (6.9%), liver dysfunction (5.9%), and loss of appetite (4.9%). Most adverse events were minor, ranging from grades 1 to 3. The all-cause mortality rate was 10.8%, and no molnupiravir-related deaths were observed. Conclusions: Molnupiravir treatment is acceptable and safe in older patients with COVID-19 aged ≥ 80 years.
RESUMO
The coronavirus disease 2019 (COVID-19) pandemic has restricted many medical practices. We aimed to investigate the impact of the COVID-19 pandemic on the number of bronchoscopies, outpatients, and hospital admissions. We retrospectively analyzed the number of outpatients, admissions, and bronchoscopies performed between March 2020 and May 2022. We defined "Peak month of the pandemic," "Wave of the pandemic," "Month in the wave," and "Period of a state of emergency" for each analysis. In the first year of the COVID-19 pandemic, analysis of variance (ANOVA) in linear mixed models indicated significant effects of "month in each wave" on the number of bronchoscopies (P = .003), outpatients (P = .041), and admissions (P = .017). The number of outpatients, admissions, and bronchoscopies was significantly influenced by the first wave of the COVID-19 pandemic. In contrast, in the second year of the COVID-19 pandemic, a mixed-ANOVA indicated significant effects of "month in each wave" only on the number of outpatients (P = .020) but no significant effects on the number of bronchoscopies (P = .407) and admissions (P = .219). During the second year of the pandemic, the number of bronchoscopies and admissions was not significantly affected by the waves of the pandemic. There were no significant differences in the number of admissions and bronchoscopies between the fourth and sixth waves. Although the number of bronchoscopies was found to be significantly affected in the early stages of the COVID-19 pandemic, the impact of the pandemic was much more limited thereafter.

Mycobacterium farcinogenes is the causative agent of bovine farcy. M. farcinogenes shares common properties with rapidly growing mycobacteria, and distinguishing between M. farcinogenes and M. fortuitum is reportedly complex and challenging. Moreover, few studies have isolated M. farcinogenes from human clinical samples. A previously healthy 37-year-old male construction worker presented to the emergency department after a severe injury and was diagnosed with a Gustilo-Anderson type â ¢A fracture. After an uneventful postoperative period of two months, he experienced pain and serous discharge from the upper shin and lower calf region. Frequent debridement provided no relief, and the pathology cultures of the tissue were negative. However, M. farcinogenes was isolated from the fluid of the wound. The patient's symptoms gradually improved with anti-mycobacterial drug treatment. Nontuberculous mycobacterial infections, including those caused by M. farcinogenes, should be considered in patients developing soft tissue infections despite negative pyogenic bacterial cultures several months after sustaining an open fracture.
RESUMO
The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is having serious medical, social, and economic impacts worldwide. COVID-19 may lead to a variety of complications, including rhabdomyolysis. Although rhabdomyolysis is a rare complication, it can lead to severe kidney damage. Recent studies suggest that rhabdomyolysis caused by SARS-CoV-2 is more common in middle-aged and older men with severe COVID-19. Herein we report a case of rhabdomyolysis in a young woman with moderate COVID-19. She had a habit of muscle training. She presented with moderate COVID-19 and acute rhabdomyolysis that required a large volume of fluid infusion in addition to dexamethasone and remdesivir. Clinicians should pay attention to the development of rhabdomyolysis in patients with COVID-19, especially those with a habit of strenuous exercise or muscle training, even if they are young and have moderate COVID-19.
RESUMO
Background: The coronavirus disease 2019 (COVID-19) pandemic is associated with a heavy burden on patient's mental and physical health, regional healthcare resources, and global economic activity. An aging society such as Japan has many retirement homes and long-term stay hospitals for the elderly and their inhabitants. During the COVID-19 pandemic, disease clusters are often identified in retirement homes and long-term stay hospitals. Although we hypothesize that additional burdens of nursing care for elderly patients will reinforce the anxiety and exhaustion of medical staff and healthcare resources in the aging society, the actual situation is not well understood. In this study, we aimed to evaluate the current situation and countermeasures of the COVID-19 pandemic in the aging society. Methods: We reviewed COVID-19 patients who required hospitalization at the National Hospital Organization Kyoto Medical Center, a 600-bed capacity hospital located in Kyoto, Japan, between 1 April 2020 and 31 March 2021. We assessed the characteristics of the COVID-19 patients, disease severity, duration of hospitalization, outcome at discharge, degree of activities of daily living (ADLs), and complications unique to elderly patients. Results: We enrolled 118 patients who required hospitalization during the study period. Approximately 40% of the patients were aged ≥ 80 years. Dementia (27.1%) was the most prevalent underlying disease, followed by diabetes mellitus (23.7%) and chronic kidney disease (23.7%). Approximately 60% of hospitalized COVID-19 patients had impaired ADL at admission. The COVID-19 patients aged 80 years or older required significantly more longer-term hospitalization than the COVID-19 patients aged under 80 years (15.5 ± 8.2 vs. 13.1 ± 7.7, P = 0.032). In elderly patients aged 80 years or older, approximately 50% of patients had geriatric mental disorders, and approximately 70% had bedridden status and feeding difficulty. Poor ADL at admission was significantly associated with COVID-19 mortality (Odds ratio, 5.6; 95% confidence interval, 1.04-45.2; p-value = 0.044). Conclusions: The proportion of elderly patients aged 80 years or older was relatively high during the hospitalization for COVID-19. Poor ADL at admission in these elderly patients was significantly associated with poor prognosis of COVID-19. We should keep in mind that healthcare workers are forced to have an additional burden of nursing care in the aging society during the COVID-19 pandemic. Therefore, interventions to reduce the burden are urgently required.
RESUMO
BACKGROUND AND OBJECTIVE: Although older patients with coronavirus disease 2019 (COVID-19) are at the high risk of exacerbation that requires treatment with remdesivir, the safety of this medication is unclear in clinical practice, especially among older patients. We aimed to retrospectively evaluate the safety of remdesivir in older patients with COVID-19 who required hospitalization in our institute. METHODS: We reviewed patients with COVID-19 who were treated with remdesivir at our institute between July 2020 and May 2021. We defined older patients as those aged 80 years or older at admission; all other patients were defined as younger patients. We evaluated the safety of remdesivir by examining the incidence of discontinuation of remdesivir treatment because of adverse events and the incidence of any adverse events. RESULTS: A total of 80 patients were included in this study. Compared with younger patients, fewer older patients were treated with remdesivir for more than 5 days: 4 (15.4%) vs 23 (42.6%). Discontinuation of remdesivir because of adverse events occurred in one older patient (3.9%) and four younger patients (7.4%) [p > 0.99]. Remdesivir-induced liver dysfunction was the most frequent adverse event, which occurred in 29 (36.3%) patients. There were no significant differences in the incidence of remdesivir-induced liver dysfunction, renal dysfunction, and fatigue. CONCLUSIONS: The safety of remdesivir was suggested to be comparable between patients older than 80 years of age and patients younger than 80 years of age. The results of this study may encourage the administration of remdesivir to this older patient group.

Background: The coronavirus disease-2019 (COVID-19) pandemic is associated with a heavy burden on the mental and physical health of patients, regional healthcare resources, and global economic activity. While understanding of the incidence and case-fatality rates has increased, there are limited data concerning seroprevalence of antibodies against the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) in healthcare workers during the pre-pandemic period. This study aimed to quantitatively evaluate seroprevalence of SARS-CoV-2 antibodies in healthcare workers in the southern part of Kyoto city, Japan. Methods: We prospectively recruited healthcare workers from a single hospital between April 10 and April 20, 2020. We collected serum samples from these participants and quantitatively evaluated SARS-CoV-2 IgG antibody levels using enzyme-linked immunosorbent assays. Results: Five (5.4%), 15 (16.3%), and 72 (78.3%) participants showed positive, borderline, and negative serum SARS-CoV-2 IgG antibody status, respectively. We found the mean titer associated with each antibody status (overall, positive, borderline, and negative) was clearly differentiated. Participants working at the otolaryngology department and/or with a history of seasonal common cold symptoms had a significantly higher SARS-CoV-2 IgG antibody titer (p = 0.046, p = 0.046, respectively). Conclusions: Five (5.4%) and 15 (16.3%) participants tested positive and borderline, respectively, for SARS-CoV-2 IgG antibody during the COVID-19 pre-pandemic period. These rates were higher than expected, based on government situation reports. These findings suggest that COVID-19 had already spread within the southern part of Kyoto city at the early stage of the pandemic.

A 51-year-old woman presented with flexion contractures of the legs. Physical examination showed decreased passive movements of the bilateral hip and knee joints without muscle spasms or neurological abnormalities. Laboratory evaluation showed no response of ACTH or plasma cortisol to stimulation with CRH or insulin. Diagnosis of isolated adrenocorticotropic hormone deficiency was made. The patient was started on prednisolone 5 mg daily, and flexion contractures of the legs rapidly disappeared. Although the musculoskeletal manifestation of this patient is similar to that of stiff-person syndrome, flexion contracture of the legs associated with adrenocortical insufficiency seems to be a separate disease entity from stiff-person syndrome.
