Anti-Yo antibody-positive paraneoplastic cerebellar degeneration in a patient with possible cholangiocarcinoma: A case report and review of the literature.

World J Clin Cases 2021 Jun;9(17):4423-4432

Department of Neurology, Affiliated Zhejiang Hospital, Zhejiang University School of Medicine, Hangzhou 310000, Zhejiang Province, China.

Background: Paraneoplastic cerebellar degeneration (PCD), which is rare in clinical practice, is closely related to autoimmunity. Cases positive for anti-Yo antibodies (anti-Purkinje cytoplasmic antibody 1) are the main subtype of PCD. PCD is subacute cerebellar degeneration, and while it progresses over weeks to months, its resultant deficits last much longer. Read More

Extragonadal teratomas in women and adolescent girls: A systematic review.

Eur J Obstet Gynecol Reprod Biol 2021 May 7;262:134-141. Epub 2021 May 7.

Department of Obstetrics and Gynaecology, National University Hospital, 5 Lower Ridge Road, 119074, Singapore. Electronic address:

Introduction: Extragonadal teratomas (EGTs) are rare and the commonest intra-abdominal subtype is omental. We present two cases: 1) a parasitic omental teratoma likely secondary to auto-amputation of an ovarian teratoma with subsequent omental reimplantation and 2) an omental immature teratoma likely due to parthenogenetic activation of displaced primordial germ cells. We subsequently conduct a systematic review to characterise EGTs. Read More

Accurate Diagnosis of Adnexal Torsion-Not Only for Expert Sonographers: A Retrospective Cohort Analysis.

J Ultrasound Med 2021 May 20. Epub 2021 May 20.

Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel.

Objectives: The aim of the study was to evaluate the clinical and sonographic parameters associated with a correct or incorrect diagnosis of adnexal torsion made by resident/attending physicians who are not expert sonographers.

Methods: A retrospective study design included women who presented to the Emergency Department (ED) of a tertiary medical center between 2010 and 2019 with acute lower abdominal pain, who were subsequently diagnosed laparoscopically with adnexal torsion.

Systematic comparison of ligand-based and structure-based virtual screening methods on poly (ADP-ribose) polymerase-1 inhibitors.

Brief Bioinform 2021 May 3. Epub 2021 May 3.

Xiangya School of Pharmaceutical Sciences, Central South University, China.

The poly (ADP-ribose) polymerase-1 (PARP1) has been regarded as a vital target in recent years and PARP1 inhibitors can be used for ovarian and breast cancer therapies. However, it has been realized that most of PARP1 inhibitors have disadvantages of low solubility and permeability. Therefore, by discovering more molecules with novel frameworks, it would have greater opportunities to apply it into broader clinical fields and have a more profound significance. Read More

Surgical Control of Bleeding From Ovarian Torsion in the Setting of Immune Thrombocytopenic Purpura Without Splenectomy.

Am Surg 2021 Apr 18:31348211011128. Epub 2021 Apr 18.

Department of Surgery, Division of Pediatric Surgery, University of Mississippi Medical Center, Jackson, MS, USA.

Immune thrombocytopenic purpura (ITP) is a disorder caused by autoimmune antibodies which target glycoprotein IIb/IIIa complex or other platelet membrane antigens leading to platelet destruction. These platelets are then cleared by the spleen resulting in thrombocytopenia. Immune thrombocytopenic purpura affects about 1 to 6. Read More

Complete Laparoscopic Removal and Staging of a Large Ovarian Malignancy: A Case Report.

Am J Case Rep 2021 Apr 16;22:e930659. Epub 2021 Apr 16.

Department of Minimally Invasive Surgery, The Marchand Institute for Minimally Invasive Surgery, Mesa, AZ, USA.

BACKGROUND Advances in minimally invasive surgery are essential for the improvement of patient care, overall health care efficiency, and total cost reductions. Morcellation, the technique used in the present case, is often used to aid minimally invasive laparoscopic procedures, whereby larger tissue specimens are broken down and divided to be removed via smaller incisions. Morcellation has become controversial in the medical community owing to the risk of the procedure spreading an occult malignancy. Read More

The dystonia gene THAP1 controls DNA double-strand break repair choice.

Mol Cell 2021 Jun 14;81(12):2611-2624.e10. Epub 2021 Apr 14.

Laboratory of Genome Integrity, National Cancer Institute, NIH, Bethesda, MD, USA. Electronic address:

The Shieldin complex shields double-strand DNA breaks (DSBs) from nucleolytic resection. Curiously, the penultimate Shieldin component, SHLD1, is one of the least abundant mammalian proteins. Here, we report that the transcription factors THAP1, YY1, and HCF1 bind directly to the SHLD1 promoter, where they cooperatively maintain the low basal expression of SHLD1, thereby ensuring a proper balance between end protection and resection during DSB repair.

BMJ Case Rep 2021 Apr 5;14(4). Epub 2021 Apr 5.

Department of Pediatric Endocrine, Parc Tauli Foundation-UAB University Institute, Sabadell, Catalunya, Spain

The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, a spectrum of anomalies arising from incomplete development of the Müllerian ducts, is characterised by congenital aplasia of the uterus and upper part of the vagina, often in the absence of other phenotypical abnormalities. We report the case of a 13-year-old girl referred to our endocrinology unit after an incidental finding of uterine agenesis during laparoscopy to correct suspected ovarian torsion. Initial transabdominal ultrasonography found no uterus. Read More
