Article Synopsis
  • Researchers conducted a comprehensive analysis of anti-PIT-1 hypophysitis cases, revealing a new instance linked to immune checkpoint inhibitor therapy.
  • All 9 patients had significantly low levels of key hormones like growth hormone and prolactin, with some exhibiting atrophy of the pituitary gland and associations with thymoma and lymphoma.
  • The study detected high levels of anti-PIT-1 antibodies and abnormal PIT-1 expression within tumor tissues, shedding light on the autoimmune aspects of paraneoplastic hypophysitis.

Kenny-Caffey syndrome type 2 (KCS2) is an extremely rare skeletal disorder involving hypoparathyroidism and short stature. It has an autosomal dominant pattern of inheritance and is caused by variants in the FAM111 trypsin-like peptidase A () gene. This disease is often difficult to diagnose due to a wide range of more common diseases manifesting hypoparathyroidism and short stature.

There is uncertainty regarding the need for COVID-19 peri-vaccination glucocorticoid coverage in patients with adrenal insufficiency. In this survey conducted in a single tertiary medical institution, 167 consecutive outpatients taking physiological glucocorticoids because of adrenal insufficiency were included. The patients declared if they developed an adrenal crisis after vaccination, and the amount and duration of an increase in their glucocorticoid dosage, if any.

Resistance against macrolide antibiotics in is becoming non-negligible in terms of both appropriate therapy and diagnostic stewardship. Molecular methods have attractive features for the identification of as well as its resistance-associated mutations of 23S ribosomal RNA (rRNA). The automated molecular diagnostic sytem can identify macrolide-resistant .

Metastasis to the skeletal muscles is uncommon. We report a case which was strongly suspected to have psoas and gluteus muscle metastases from uterine carcinosarcoma. A 68-year-old woman (gravida, 2; para, 0) underwent retroperitoneal endoscopic paraaortic lymphadenectomy, laparoscopic modified radical hysterectomy, bilateral salpingo-oophorectomy and pelvic lymphadenectomy for uterine carcinosarcoma, suspected to be stage IB.

Article Synopsis
  • This study investigated the roles of different types of hysterectomy (simple vs. modified radical) in treating endometrial cancer in a collaborative setting involving 11 medical institutions over a period of 11 years.
  • It analyzed data from 1,335 patients who underwent surgery, highlighting that 73.6% had a simple hysterectomy while 26.4% had a modified radical hysterectomy.
  • The findings revealed no significant difference in local recurrence rates between the two surgical methods, suggesting that the more extensive modified radical hysterectomy may not be necessary for effective treatment.

Objective: Because it is difficult to diagnose accurately whether uterine corporeal mesenchymal tumors are benign or malignant before surgery, an understanding of the characteristics of patients with uterine sarcomas occurring in the postmenopausal period is required.

Methods: We retrospectively reviewed the cases of women who underwent surgery for uterine mesenchymal tumors at our hospital.

Results: Among 487 operated cases, 447 tumors occurred in the premenopausal period and 40 occurred in the postmenopausal period.

Aim: To investigate the differences in leiomyoma pathophysiology by patient age at the time of surgery and the possible significance of postmenopausal uterine leiomyomas, particularly variants.

Methods: We retrospectively reviewed data from 471 patients who underwent surgery for uterine leiomyomas and evaluated their clinical data.

Results: Overall, 441 (93.

We report struma ovarii in a case that had hyperthyroidism and was treated with laparoscopic tumor resection. A 40-year-old Japanese woman presented with tachycardia, finger tremor, and weight loss. Although blood examination showed hyperthyroidism, test results for thyroid stimulating hormone receptor antibody and thyroid stimulating antibody were negative, and thyroid scintigraphy showed no abnormal findings.

A 61-year-old Japanese woman was diagnosed with FIGO Stage IB endometrioid cancer (EC) combined with large cell neuroendocrine carcinoma (LCNEC). Metastasis to the lymph nodes in the right bronchopulmonary area, mediastinum and brain were also identified. The patient eventually developed pleuritis and pericarditis carcinomatosa, and died of cancer at 51 months after surgery.
