Tetanus is a nervous system disorder characterized by muscular spasms and autonomic hyperactivity, such as unstable blood pressure. We herein report a case of tetanus in a patient in shock complicated with a rectus sheath hematoma caused by rupture of a pseudo-aneurysm of the inferior epigastric artery. A rectus sheath hematoma might be misdiagnosed as unstable blood pressure associated with autonomic hyperactivity, which is usually observed in patients with tetanus. The possibility of the occurrence of bleeding complications should be considered if a patient with tetanus has severe and persistent blood pressure reduction.

Objective To identify factors associated with pneumomediastinum during management of connective tissue disease (CTD)-related interstitial lung disease (ILD). Methods Patients diagnosed with pneumomediastinum after the initiation of corticosteroid therapy for their CTD-ILD were enrolled. The baseline characteristics of patients who developed pneumomediastinum after the initiation of corticosteroid therapy (n=13, all occurring within 120 days) were compared to those of patients who did not develop pneumomediastinum (n=49). ⋯ LDH showed a sensitivity of 61.5% and the highest specificity of 87.8%. Importantly, combining these markers resulted in the highest sensitivity of 100% and a specificity of 71.4%. Conclusion A low BMI and high serum LDH levels at baseline are useful predictive factors for pneumomediastinum development in CTD-ILD patients.

Objective This study aimed to elucidate the effects of early macrolide administration on genetically confirmed pertussis-induced cough in adolescents and adults. Methods This single-center, retrospective cohort study examined the effects of the early administration of macrolides and antitussive agents on cough secondary to pertussis. We divided the patients into two groups based on the median duration from the beginning of the cough to the initiation of macrolide administration: early macrolide administration group (EMAG) and non-early macrolide administration group (NEMAG). ⋯ Antitussive agents did not affect the cough. Conclusion The early administration of macrolides, but not antitussive agents, is effective for treating pertussis. Therefore, macrolides should be administered as soon as possible for this disease.

Objective The low-density lipoprotein cholesterol (LDL) level is known to increase following the treatment of hepatitis C virus (HCV) infection using direct-acting antiviral agents (DAAs). This study aimed to investigate the changes in the lipid profiles, including small-dense LDL cholesterol (sdLDL), in HCV patients treated with DAAs. Patients We retrospectively assessed 67 HCV patients who achieved sustained virological response with DAA administration and were observed for more than 2 years, of whom 32 were on daclatasvir/asunaprevir, 14 were on sofosbuvir/ledipasvir, and 21 were on sofosbuvir/ribavirin. ⋯ The Kaplan-Meier curve indicated that patients with high values of LDL, albumin, muscle attenuation and visceral to subcutaneous adipose tissue area ratio were at increased risk for elevation of sdLDL over 35 mg/dL (log-rank test: p<0.001; p=0.008, p=0.002 and p=0.042, respectively). A multivariate analysis performed on the factors contributing to elevation of sdLDL 2 years after DAA treatment (≥35.0 mg/dL) revealed pretreatment LDL (≥91.0 mg/dL) and muscle attenuation (≥33.7 HU) as significant factors (p=0.007 and p=0.032, respectively). Conclusion SdLDL increased continuously after DAA treatment, and high LDL levels and low intramuscular fat deposition before treatment contributed to elevated sdLDL levels after treatment.

Acute liver injury (ALI) has been rarely reported as a clinical finding of adult T-cell leukemia/lymphoma (ATLL). A 74-year-old Japanese female patient who was histologically diagnosed as having autoimmune hepatitis (AIH) one year earlier, showed elevations in her aminotransferase and total bilirubin levels, and this was considered to be an exacerbation of AIH. ⋯ The biopsy revealed CD4+ and CD8+, but not CD20+ lymphocytes. Thus, the ALI in the patient was due to T-cell infiltration into the liver, and not due to an exacerbation of AIH.
