Mixed gonadal dysgenesis with gonadoblastoma diagnosed by prophylactic laparoscopic gonadectomy: A case report.

Mixed gonadal dysgenesis (MGD) is a disorder of sex development caused by mosaicism of the Y chromosome, represented by 45,X/46,XY. Prophylactic gonadectomy is recommended as soon as possible after its diagnosis, owing to a high risk of malignancy. In the present case, a 21-year-old woman presented with primary amenorrhea.

An Increase in Peroxiredoxin 6 Expression Induces Neurotoxic A1 Astrocytes in the Lumbar Spinal Cord of Amyotrophic Lateral Sclerosis Mice Model.

Amyotrophic lateral sclerosis (ALS) is a severe neurodegenerative disease with selective degeneration of motor neurons. It has been reported that an increase in the levels of inflammatory cytokines and glial cells such as reactive astrocytes is closely involved in the pathological progression of ALS. Recently, the levels of neuropathic cytotoxic (A1) astrocytes among reactive astrocytes have reportedly increased in the central nervous system of ALS mice, which induce motor neuron degeneration through the production of inflammatory cytokines and secretion of neuropathic factors.

Measures for pregnant women with coronavirus disease 2019 at the National University Hospital: 34th National University Perinatal Medical Center Conference.

As 2 years have passed since the outbreak of coronavirus disease 2019 (COVID-19), we had an examination of the measures taken at the perinatal medical and child centers during this period at 42 National University Hospital. The first questionnaire survey was conducted during March 17-25, 2022 and the second questionnaire survey was conducted during April 4-30, 2022. For the treatment of pregnant women with COVID-19, a public health center-coordinated triage system had been created and implemented in each region and prefecture.

Indoleamine 2,3-dioxygenase and trophoblast invasion in caesarean scar pregnancy: Implications for the aetiopathogenesis of placenta accreta spectrum.

Immunohistochemical localisation of indoleamine 2,3-dioxygenase was studied in order to better understand the pathophysiology of placenta accreta spectrum. In the decidua staining for indoleamine 2,3-dioxygenase was found in the glandular epithelium with some additional positive cells. Extravillous cytotrophoblast invasion was present in the myometrium which was not covered by the decidual tissue whereas myometrial invasion of cytotrophoblasts was absent where this tissue lay deep to decidua.
