The results indicate that GIM is a promising treatment for work-related chronic stress, and further studies are recommended.

Our study suggests a reduced number of germ cells in undescended testes from week 28 of gestation and germ cell hypoplasia as a consequence of continued postnatal undescended testicular position. Cryptorchidism may result from abnormal development of the caudal developmental field.

Music therapy (MT) interventions and skin-to-skin care (SSC) both aim to address the varied needs of preterm infants, including sensory regulation and stress reduction, inclusion of parents in their infant’s care, support of parents’ emotional state, and enhancing the parent–infant attachment process. Few studies have investigated the combination of both modalities through randomized controlled trials. Evidence of longer-term effects is missing. This article presents a study protocol that will investigate the effects of combined family-centered MT intervention and SSC on preterm-infants’ autonomic nervous system (ANS) stability, parental anxiety levels, and parent–infant attachment quality. 12 clusters with a total of 72 preterm infants, with their parents, will be randomized to one of two conditions: MT combined with SSC or SSC alone. Each parent–infant dyad will participate in 3 sessions (2 in the hospital and a 3-month follow-up). The primary outcome of preterm infants’ ANS stability will be measured by the high frequency power of their heart rate variability. Secondary outcomes will be physiological measures and behavioral states in infants and anxiety and attachment levels of parents. This trial will provide important, evidence-based knowledge on the use of the “First Sounds: Rhythm, Breath, and Lullaby” model of MT in neonatal care, through an intervention that is in line with the Newborn Individualized Developmental Care and Assessment Program model for supportive developmental care of preterm infants and their parents. Ethical approval (no. 0283-15) was granted from the local Institutional Review Board in April 2017. This trial is registered in ClinicalTrials.gov, NCT03023267.

We recommend laparoscopy as a safe procedure which leads to a diagnosis in patients with impalpable testes; the advent of laparoscopic procedures makes definitive treatment possible in about 50% of such patients. Open procedures will be indicated only to ascertain the quality and treatment of intracanalicular testes.

Human placental lactogen (HPL) is produced in large amounts in normal pregnancies. We report a pregnancy with complete lack of HPL and the placental variant of the human growth hormone HGH-V. The pregnancy resulted in a severely growth-retarded but otherwise normal male baby. PCR analysis of DNA extracted from the placenta showed that the HPL encoding genes hPL-4 and hPL-3 were deleted along with the human growth hormone variant gene (hGH-V), which is located between these two active hPL genes and also expressed in the normal placenta. Of the five members of this multigene family, hGH-N, which is expressed in the pituitary gland, and hPL-1, a presumed pseudogene, were left intact. The latter (hPL-1) was expressed as RNA transcripts only at very low levels as is usually reported in normal pregnancies. Analysis of the parents' DNA showed that both of them carried a different heterozygous deletion at the 3' end of the hGH/hPL locus.
