RESUMO
An 83-year-old woman with asymptomatic pulmonary sarcoidosis presented to our hospital with fever and malaise for three months. Abdominal CT showed splenomegaly, and bone marrow examination revealed non-caseating granulomas. Pancytopenia was diagnosed due to bone marrow and splenic lesions of sarcoidosis. Steroid pulses were administered, but the patient died without response to treatment. Pathological autopsy results showed non-caseating granulomas and hemophagocytosis in the spleen and bone marrow. This suggested hemophagocytic syndrome, which was not suspected before death, in addition to sarcoidosis. In patients with splenomegaly and pancytopenia with history of pulmonary sarcoidosis, hemophagocytic syndrome should be considered in differential diagnosis.
RESUMO
Hyperosmolar hyperglycemic syndrome is a life-threatening diabetic emergency that manifests as altered mental status. An otherwise healthy 40-year-old man presented to our emergency department with headache and severe hypertension. Brain magnetic resonance imaging showed evidence of posterior reversible encephalopathy syndrome, a usually reversible neurological syndrome characterized by subcortical vasogenic oedema. This first reported case details posterior reversible encephalopathy syndrome concurrent with hyperosmolar hyperglycemic syndrome. Prompt diagnosis and management were essential to avoid non-reversible consequences.

There is an urgent need for development of better diagnostic strategies to improve outcomes in patients with invasive pulmonary aspergillosis (IPA). We hypothesized that lung perfusion single-photon emission computed tomography (SPECT) may be more sensitive and specific than computed tomography (CT) of the chest for detection of IPA because it is an angioinvasive pulmonary infection with characteristics that are different from those of bacterial pneumonia. We used SPECT with injection of technetium-99m-labeled macroaggregated albumin ([99mTc]MAA) to measure pulmonary perfusion in noninfected mice, mice with IPA, and mice with bacterial pneumonia. Histopathologic analysis was performed to evaluate the correlation between the perfusion defect and mould invasion. We also attempted to quantitatively evaluate the SPECT images to identify differences in decreased perfusion levels in affected areas in the mouse lung. Histopathologic analysis in the IPA mouse model showed a clear match between areas with a perfusion defect and the presence of mold, indicating that the location of the perfusion defect on a SPECT image reflects angioinvasion of the mould in the lungs. Some of these perfusion defects could be seen before appearance of the infiltrate of CT images. Quantitative analysis confirmed that perfusion in the affected areas was significantly decreased in the IPA model but not in the bacterial pneumonia model (P < .0001). This imaging method may be preferable to the alternative methods presently used to identify the presence of mold in a patient's lungs.

BACKGROUND: Mycoplasma pneumoniae strains with resistance to macrolides have been spreading worldwide. Here, we aimed to clarify which antimicrobial agent is a better treatment for patients with M. pneumoniae pneumonia in a setting with large epidemics of macrolide resistance. METHODS: Adult patients hospitalized with laboratory-confirmed M. pneumoniae pneumonia from 2010 to 2013 were identified from the Japanese Diagnosis Procedure Combination national database. Drug switching, length of stay (LOS), 30-day mortality, and total costs for patients who underwent macrolide, quinolone, and tetracycline therapy were compared using propensity score analyses. RESULTS: Eligible patients (N = 1650) from 602 hospitals were divided into the macrolide group (n = 508), quinolone group (n = 569), or tetracycline group (n = 573). We found that 52.8%, 21.8%, and 38.6% of patients in the macrolide, quinolone, and tetracycline groups, respectively, had to switch drugs (P < .0001). There was no significant difference in the LOS and the 30-day mortality rates among these 3 groups. Cost was highest in the quinolone group (P = .0062). The propensity score-matched pairs (n = 487×2) generated from the quinolone and tetracycline groups also showed a lower proportion of patients who require switches in the quinolone group than in the tetracycline group (21.2% vs 39.6%, P < .0001) but not in the LOS, mortality, and cost. CONCLUSIONS: There were no significant differences in the LOS and mortality among any antimycoplasmal drugs as initial treatment for hospitalized M. pneumoniae pneumonia patients despite the lower switching rate in the quinolone group.

BACKGROUND: There is conflicting evidence regarding the benefit of adjunctive corticosteroid therapy in patients with Mycoplasma pneumoniae pneumonia. We hypothesised that corticosteroid therapy could reduce mortality and length of stay (LOS) in such patients. METHODS: Adult patients with M. pneumoniae pneumonia from January 2010 to December 2013 were identified from the Japanese Diagnosis Procedure Combination inpatient database. The effects of low-dose and high-dose corticosteroid therapies on mortality, LOS, drug costs and hyperglycaemia requiring insulin treatment were evaluated using propensity score analyses. RESULTS: Eligible patients (n = 2228) from 630 hospitals were divided into no-corticosteroid (n = 1829), low-dose corticosteroid (n = 267) and high-dose corticosteroid (n = 132) groups. The propensity score-matched pairs were generated from no-corticoid and low-dose corticoid groups (251 pairs), or no-corticoid and high-dose corticosteroid groups (120 pairs). Adjunctive corticosteroid therapy did not decrease 30-day mortality. In addition, both low-dose and high-dose corticosteroid therapies were associated with increases in LOS. Furthermore, hyperglycaemia requiring insulin treatment and drug cost increased with corticosteroid use. CONCLUSIONS: Adjunctive treatment with low-dose or high-dose corticosteroids may not be beneficial in M. pneumoniae pneumonia.

BACKGROUND: Non-AIDS-defining cancers (NADCs) in patients infected with HIV have recently attracted attention because of the improved survival of this patient population. To obtain accurate data, a longitudinal study is warranted for the nationwide surveillance of the current status and national trend of NADCs in patients infected with HIV in Japan. SETTING: An annual nationwide surveillance of NADCs in patients infected with HIV-1 in Japan from 1999 to 2021. METHODS: An annual questionnaire was sent to 378 HIV/AIDS referral hospitals across Japan to collect data (clusters of differentiation 4-positive lymphocytes, time of onset, outcomes, and antiretroviral therapy status) of patients diagnosed with any of the NADCs between 1999 and 2021. RESULTS: The response and case-capture rates for the questionnaires in 2021 were 37.8% and 81.2%, respectively. The number of reported NADC cases subsequently increased since the beginning of this study. Evaluation of the case counts of NADCs demonstrated a high incidence of lung, colorectal, gastric, and liver cancers as the top 4 cancers. Pancreatic cancer (0.63), lung cancer (0.49), and leukemia (0.49) had the highest mortality rates among the NADCs. Trends of NADCs regarding transmission routes were maintained over the years in male individuals who have sex with male individuals compared with heterosexual male individuals and female individuals. CONCLUSIONS: We demonstrated an increasing trend in the incidence of NADCs over a period of 23 years in Japan. The current data highlighted the importance of raising awareness regarding cancer management for patients infected with HIV in Japan.

This case report highlights the rare occurrence of Wernicke encephalopathy caused by malnutrition in a depressed patient with atypical imaging findings. A 60-year-old female with depression developed a disturbance of consciousness owing to Wernicke encephalopathy. Magnetic resonance imaging showed abnormal signals in the thalamus and mammillary bodies around the third ventricle, cerebral aqueduct, and fourth ventricle. Abnormal signals were also present in the cerebral cortex around the central sulcus, and an intracranial hemorrhage from the thalamus was observed. Therefore, clinicians should consider Wernicke encephalopathy in the differential diagnosis of altered consciousness in depressed patients. Early assessment of nutritional status and prompt intervention are crucial in cases of prolonged depression-related malnutrition.
RESUMO
Purpose Elderly trauma patients have a higher risk of severe disability and death, and this outcome burden in elderly trauma patients must be addressed in countries in which the population is aging. The clarification of the unique clinical features of elderly people who have experienced trauma is important. The purpose of this study is to evaluate the significance of the treatment for elderly severe trauma patients based on the prognosis and total hospital cost. Methods Trauma patients transferred to our emergency department (ED) and admitted to our intensive care unit (ICU) directly or through emergency surgery between January 2013 and December 2019 were examined. We divided patients into three groups: <65 years old (Group Y); 65-79 years old (Group M); and ≥80 years old (Group E). We compared the pre- and post-trauma American Society of Anesthesiology Physical Status (ASA-PS) score and the Katz Activities of Daily Living (ADL) questionnaire at arrival among the three groups. In addition, the duration of ICU and hospital stays, hospital mortality, and total treatment costs were compared. Results There were 1,652 patients admitted to ICU through the ED from January 2013 to December 2019. Of those patients, 197 trauma patients were analyzed. There was no significant difference in injury severity scores between the groups. Significant differences in both the ASA-PS and Katz-ADL scores in posttrauma status were observed among the three groups (posttrauma ASA-PS, 2.0 (2.0, 2.8) in Group Y, 3.0 (2.0, 3.0) in Group M, 3.0 (3.0, 3.0) in Group E, p < 0.001*, posttrauma Katz-ADL, 10.0 (3.3, 12.0) in Group Y, 5.5 (2.0, 10.0) in Group M, 2.0 (0.5, 4.0) in Group E, p < 0.001). The duration of both ICU and hospital stay was significantly longer in Group E compared to the other groups (ICU stay, 4.0 (3.0, 6.5) days in Group Y, 4.0 (3.0, 9.8) days in Group M, 6.5 (3.0, 15.3) days, p = 0.006, hospital stay, 16.9 (8.6, 33.0) days in Group Y, 26.7 (12.0, 51.8) days in Group M, 32.5 (12.8, 51.5) days in Group E, p = 0.005). ICU and hospital mortality were highest in Group E compared with the other groups, but the differences were not significant. Finally, the total hospital cost in Group E was significantly higher than the other groups. Conclusions In elderly trauma patients who required intensive care, PS and ADL in posttrauma status were worse, ICU and hospital stays were longer, and ICU and hospital mortality were higher compared with younger patients. In addition, medical costs were greater in elderly patients. It is supposed that the therapeutic effect observed in young trauma patients cannot be expected in elderly trauma patients.
RESUMO
The aim of the present study was to evaluate the usefulness of measuring whole blood coagulation with Sonoclot to predict return of spontaneous circulation (ROSC) in patients with out-of-hospital cardiopulmonary arrest (OHCA). This was a prospective, observational clinical study on patients with OHCA who were transferred to our emergency department between August 2016 and July 2018. Patients were divided into two groups: patients with return of spontaneous circulation (ROSC[+] group) and those without (ROSC[-] group). We compared the activated clotting time (ACT), clot rate (CR), and platelet function (PF) as measured with Sonoclot, and the fibrinogen degradation products (FDP) level and D-dimer level between the two groups. We analyzed 87 patients: 37 in the ROSC(+) and 50 in the ROSC(-) groups. Regarding ACT, CR, PF, FDP, and D-dimer, we used receiver operating characteristic (ROC) curves to examine how well each factor predicts ROSC. The area under the ROC curve (AUC) of CR was higher than that of the FDP and D-dimer levels. Among patients with cardiogenic cardiac arrest, the AUC of CR was higher than the AUCs of other coagulation factors. In conclusion, viscoelastic blood coagulation measurements using Sonoclot may be useful for predicting ROSC in OHCA patients.
RESUMO
An asymmetric 1,4-addition reaction of 5H-oxazol-4-ones with alkynyl carbonyl compounds was developed, and, for the first time, high enantiomeric and geometric control was achieved to afford the thermodynamically unstable Z-isomer predominantly using chiral guanidine catalysts bearing a hydroxy group at the appropriate position. The method provides synthetically useful γ-butenolide ester bearing a chiral quaternary stereogenic center.
RESUMO
Hemolytic anemia is a rarely occurring manifestation of native valve infective endocarditis. We herein report an afebrile patient with hemolytic anemia caused by Cardiobacterium hominis endocarditis. A 60-year-old Japanese man had a history of aortic root replacement and the gradual onset of general fatigue. He had hemolytic anemia. Blood cultures detected C. hominis. A transthoracic echocardiogram showed aortic valve vegetation and periannular abscess with perforation of the non-coronary cusp. Intravascular hemolysis recovered after antimicrobial therapy, surgical removal of the vegetation and abscess, and aortic valve replacement. Subacute endocarditis should be considered if patients develop hemolytic anemia with signs of chronic inflammation without a fever.

OBJECTIVES: The accurate prevalence of acquired immunodeficiency syndrome (AIDS)-defining illnesses (ADIs) in human immunodeficiency virus (HIV)-infected patients has not been well investigated. Hence, a longitudinal nationwide surveillance study analyzing the current status and national trend of opportunistic complications in HIV-infected patients in Japan is warranted. METHODS: A nationwide surveillance of opportunistic complications in HIV-infected patients from 1995 to 2017 in Japan was conducted. An annual questionnaire was sent to 383 HIV/AIDS referral hospitals across Japan to collect information (CD4+ lymphocyte count, time of onset, outcome, and antiretroviral therapy [ART] status) of patients diagnosed with any of 23 ADIs between 1995 and 2017. RESULTS: The response and case capture rates of the questionnaires in 2017 were 53% and 76%, respectively. The number of reported cases of opportunistic complications peaked in 2011 and subsequently declined. Pneumocystis pneumonia (38.7%), cytomegalovirus infection (13.6%), and candidiasis (12.8%) were associated with the cumulative incidence of ADIs between 1995 and 2017. The mortality rate in HIV-infected patients with opportunistic complications substantially decreased to 3.6% in 2017. The mortality rate was significantly higher in HIV patients who received ART within 14 days of diagnosis of complications than in those who received ART 15 days after diagnosis (13.0% vs. 3.2%, p < 0.01). CONCLUSIONS: We have demonstrated a 23-year trend of a newly diagnosed AIDS status in Japan with high accuracy. The current data reveal the importance of Pneumocystis pneumonia as a first-onset illness and that early initiation of ART results in poor outcomes in HIV patients in Japan.

Scleredema is a rare cutaneous mucinosis characterized by diffuse swelling and non-pitting induration. A 63-year-old man reported a 5-year history of skin thickening of the trunk and a 3-week history of dyspnea. Echocardiography revealed diffuse hypokinesis. Skin biopsies obtained from the waist showed thickened dermis with mucin. Myocardial biopsies showed alcian blue-stained tissue between the muscle fibers. The patient was referred to a dermatologist for phototherapy. Cardiomyopathy should be considered in patients with scleredema. Scleredema usually has a good prognosis; however, the mortality risk could be high when accompanied by cardiomyopathy.
