Effect of radiation on serum anti-Müllerian hormone during hysterosalpingography in female infertility.

Research Question: Does radiation exposure during hysterosalpingography (HSG) negatively affect serum anti-Müllerian hormone (AMH) levels in infertile women?

Design: Prospective cohort study conducted at Songklanagarind Hospital, Thailand, between April 2021 and May 2023. Thirty-two infertile women and 34 control participants were enrolled. Serum AMH levels were assessed in the infertile group at baseline before the HSG procedure and at 1 and 3 months after the procedure.

Case report: Molecular analysis of a 47,XY,+21/46,XX chimera using SNP microarray and review of literature.

Chimerism is a very rare genetic finding in human. Most reported cases have a chi 46,XX/46,XY karyotype. Only three non-twin cases carrying both trisomy 21 and a normal karyotype have been reported, including two cases with a chi 47,XY,+21/46,XX karyotype and a case with a chi 47,XX,+21/46,XY karyotype.

Reducing Laboratory Turnaround Time in Patients With Acute Stroke and the Lack of Impact on Time to Reperfusion Therapy.

Context.—: Timely reperfusion improves the recovery of patients with acute ischemic stroke. Laboratory results are crucial to guide treatment decisions in patients when abnormal laboratory tests are suspected.

No Evidence of Abnormal Expression of Beta-Catenin and Bcl-2 Proteins in Pilomatricoma as One Clinical Feature of Tetrasomy 9p Syndrome.

Background: Little is currently known about the genetics of pilomatricoma. A number of studies have reported some evidence that this disease may have a genetic association with mutations of gene or expression of the beta-catenin protein. In this study, we reviewed literatures involving 30 patients with various genetic syndromes that have been linked to pilomatricoma and found that somatic mutations of the gene were reported in 67% of patients.

The Direct Spectrophotometric Method Is Reliable for Initial Assessment of Total Bilirubin in Neonatal Venous Plasma.

Objective: To determine the consistency of bilirubin values between the direct spectrophotometric (DS) and colorimetric diazo (diazo) methods in neonatal venous plasma specimens.

Methods: We measured the total bilirubin via the DS and diazo methods in 255 neonatal venous plasma specimens and compared the overall and subgroup results.

Results: Slight underestimation of total bilirubin values in most specimens using the DS method was observed, with higher mean biases found in higher concentrations.
