Department of Medical Genetics, Istanbul Medical Faculty, Istanbul University, Istanbul, Turkey.

Crisponi / cold-induced sweating syndrome (CS/CISS) is a rare autosomal recessive disorder characterized by episodic hyperthermia, arthrogryposis, impaired feeding ability, and respiratory distress. The classic CS/CISS is mainly associated with CRLF1 and, rarely, CLCF1. PERCHING syndrome, previously known as CS/CISS type-3 associated with biallelic pathogenic variants in KLHL7, is notable for its few overlapping manifestations. Read More

Management of atypical cases of twin-to-twin transfusion syndrome.

Best Pract Res Clin Obstet Gynaecol 2022 Mar 31. Epub 2022 Mar 31.

Department of Maternal-Fetal Medicine, Hospital Civil de Guadalajara "Dr. Juan I. Menchaca", Jalisco, Mexico.

Up to 20% of monochorionic diamniotic twin pregnancies can be complicated with twin-to-twin transfusion syndrome (TTTS). This complication is diagnosed by ultrasound demonstrating amniotic fluid discordance between both amniotic sacs, with polyhydramnios in the recipient's sac and oligohydramnios in the donor's, secondary to an imbalance in blood volume exchange between twins. Ultrasound evaluation of the amniotic fluid volume, bladder filling, and assessment of fetal Doppler parameters provide the basis for classification of TTTS, allowing severity assessment. Read More

The amniotic fluid index and oligohydramnios: a deeper dive into the shallow end.

Am J Obstet Gynecol 2022 Apr 20. Epub 2022 Apr 20.

Division of Maternal-Fetal Medicine, Department of Obstetrics and Gynecology, Maine Medical Center, Portland, ME.

Second- and third-trimester obstetrical ultrasound examinations include an amniotic fluid volume assessment. Professional organizations' clinical guidance recommends using semiquantitative techniques, such as the single deepest vertical pocket or amniotic fluid index, for this purpose. The single deepest vertical pocket is described as the preferred method of assessing amniotic fluid volume based on fewer oligohydramnios diagnoses and labor inductions with no demonstrable difference in pregnancy outcomes compared with the amniotic fluid index.

The effect of celecoxib for treatment of preterm labor on fetuses during the second trimester of pregnancy: A pilot case series.

Taiwan J Obstet Gynecol 2022 Mar;61(2):277-281

Department of Gynecology and Obstetrics, Kyoto University, 54 Shogoin Kawahara-cho, Sakyo-ku, Kyoto, 606-8507 Japan.

Objective: Although cyclooxygenase inhibitors effectively suppress uterine contraction, constriction of the fetal ductus arteriosus (DA) and oligohydramnios are major concerns. Celecoxib, a selective cyclooxygenase 2 inhibitor, is a potential potent tocolytic agent, but there are no studies that have evaluated the beneficial or adverse effects of celecoxib use on fetuses for more than 48 hours in pregnant women. We therefore aimed to evaluate the effect of middle-long-term celecoxib administration on the fetus during the second trimester of pregnancy, particularly in terms of fetal DA and amniotic fluid volume.

Tropical Infections Induced Fulminant Hepatitis in Peripartum Managed Successfully: Tales of Fate.

Cureus 2022 Feb 15;14(2):e22223. Epub 2022 Feb 15.

Department of Obstetrics and Gynaecology, Jawaharlal Nehru Medical College, Datta Meghe Institute of Medical Sciences (Deemed to be University), Wardha, IND.

Tropical diseases such as malaria, dengue, intestinal helminths, schistosomiasis, leishmaniasis, and filariasis have an essential influence on the reproductive health of patients. Various cases of pregnancy loss in unexplained circumstances are a result of underdiagnosed tropical diseases. Term pregnancy complicated by tropical diseases is a challenge for the treating clinicians as these infections tend to mimic HELLP (Hemolysis, Elevated Liver enzymes, and Low Platelets) syndrome and increase the chances of perinatal complications and maternal mortality.

Maternal and foetal physiological response of sacral surface electrical stimulation during pregnancy: A preliminary study.

Exp Physiol 2022 05 3;107(5):508-514. Epub 2022 Apr 3.

Department of Obstetrics and Gynaecology, Shiga University of Medical Science Hospital, Otsu, Japan.

New Findings: What is the central question of this study? The physiological response to sacral neuromodulation by pregnant women and foetuses has not been previously explored. What is the main finding and its importance? Sacral surface electrical stimulation had no adverse effect on pregnant women and foetuses at least 36 weeks of gestation. It may cause uterine relaxation resulting from decreased uterine artery pulsatility index and increased umbilical venous flow volume and thereby improve utero-placental perfusion and improve lower back pain.

Expanding the clinical spectrum of autosomal-recessive renal tubular dysgenesis: Two siblings with neonatal survival and review of the literature.

Mol Genet Genomic Med 2022 05 14;10(5):e1920. Epub 2022 Mar 14.

Department of Medical Genetics, Children's Hospital of Eastern Ontario, Ottawa, Ontario, Canada.

Background: Autosomal-recessive renal tubular dysgenesis (AR-RTD) is a rare genetic disorder caused by defects in the renin-angiotensin system that manifests as fetal anuria leading to oligohydramnios and Potter sequence. Although the most common outcome is neonatal death from renal failure, pulmonary hypoplasia, and/or refractory arterial hypotension; several cases have been reported that describe survival past the neonatal period.

Methods: Herein, we report the first family with biallelic ACE variants and more than one affected child surviving past the neonatal period, as well as provide a review of the previously reported 18 cases with better outcomes. Read More
