We encountered a 67-year-old Japanese man with GNE myopathy and homozygous variants (c.1807G>C, p. V603L) of the GNE gene. ⋯ Although severe heart failure is rare in GNE myopathy, mild cardiac dysfunction (ejection fraction 46.1%) was observed. Furthermore, respiratory dysfunction was noted with a preserved diaphragm.

Thyroid transcription factor 1 (TTF-1) is primarily expressed in lung and thyroid cancers, but it has also been observed in other cancers. A 60-year-old woman presented with worsening dyspnea, pleural effusion, lung metastases, a right ovarian tumor, and para-aortic intra-abdominal lymph node metastasis. ⋯ An adenocarcinoma positive for TTF-1 was identified, thus confirming the diagnosis of ovarian cancer. Our findings revealed that TTF-1 positivity does not always signify a lung cancer origin.

Objective Cortisol-producing adenoma (CPA) is a major subtype of functional adrenal tumors. CPAs are generally treated with adrenalectomy; however, it is difficult to predict the ideal duration of glucocorticoid replacement after resection. This study explored pre-operative factors predictive of glucocorticoid replacement therapy duration after CPA resection. ⋯ In multiple regression analyses, the midnight serum cortisol level and presence of lumbar compression fracture were significantly correlated with the replacement therapy duration after adjusting for other parameters. Conclusion Our results suggest that high midnight serum cortisol levels, which cause persistent suppression of the HPA axis, contribute to a delay in HPA axis recovery. Lumbar compression fracture is an important symptom that reflects the severity and persistence of cortisol secretion.

An 81-year-old woman presented to our hospital with dyspnea. She had been treated with trastuzumab for nine years. Chest radiography revealed pleural effusion. ⋯ Cardiac magnetic resonance imaging revealed increased native T1 values at the interventricular septum and apex, indicating myocardial edema or fibrosis in these areas. A transthoracic echocardiogram after half a year revealed an increase in LVEF from 25% to 48%. Serial transthoracic echocardiography and cardiac magnetic resonance imaging were useful for evaluating the cardiac structure and function in the present case of delayed trastuzumab-induced myocardial injury.

Emphysematous cholecystitis has a poor prognosis and necessitates prompt surgery or drainage. Emphysematous cholangitis (EC) is believed to have a similar clinical course, but reports are limited. ⋯ We reviewed the background, causative organisms, treatment, and outcomes of EC through a literature search. Our findings provide insights into its similarities to emphysematous cholecystitis, emphasizing the need for expeditious drainage and anaerobic bacterial coverage during antibiotic therapy.
