Reversible Wernicke encephalopathy caused by hyperemesis gravidarum in the second trimester of pregnancy: a case report.

Wernicke encephalopathy is a potentially life-threatening neurologic syndrome caused by acute thiamine (vitamin B1) deficiency. It is usually associated with excessive alcohol consumption. Less frequently, this syndrome can be caused by persistent vomiting.

Immune checkpoint CD155 promoter methylation profiling reveals cancer-associated behaviors within breast neoplasia.

Background: CD155 immune checkpoint has recently emerged as a compelling immunotherapeutic target. Epigenetic DNA methylation changes are recognized as key molecular mechanisms in cancer development. Hence, the identification of methylation markers that are sensitive and specific for breast cancer may improve early detection and predict prognosis.

Hyperreactio luteinalis incidentally found in the second trimester of pregnancy with normal hCG levels: a case report.

Hyperreactio luteinalis (HL) is a rare entity in which both ovaries are multicystic and enlarged under the action of human chorionic gonadotropin (hCG), mostly seen in the third trimester of pregnancy. This benign condition is usually asymptomatic and doesn't need any specific treatment, as the ovaries spontaneously reduce in size after birth. This is a case report of a 33-year-old woman diagnosed with hyperreactio luteinalis during the second trimester of her induced pregnancy.

Perineal endometriosis: a rare case of a unique sizeable nodule.

Endometriosis is the presence of endometrial tissue in abnormal locations outside the uterine cavity. These locations are usually the ovaries, the peritoneum, and the uterine ligaments. Less frequently, the endometrial tissue can affect the perineum especially after surgical procedures or obstetric lesions.
