Trisomy 8 is a relatively rare chromosomal abnormality. The majority of cases present with the mosaic form. Regular trisomy 8 is usually lethal and frequently results in miscarriage, while those with "trisomy 8 mosaicism" are more likely to survive. We report clinical observations and cytogenetic studies of a 13-year-old male with regular trisomy 8 and compared with those of other known cases of trisomy 8. The most discriminating findings for this condition are skeletal anomalies, restricted articular function, and speech problems. Our results are in agreement with those of previous studies for trisomy 8.

Chromosomal abnormalities of the embryo are the most common cause of first-trimester pregnancy loss. In this single-center study, we assessed the frequency and the spectrum of chromosomal abnormalities in miscarriages for each year of maternal age from 23 to 44. Cytogenetic data were obtained by conventional karyotyping of 7118 miscarriages in women with naturally conceived pregnancies.

Down syndrome (DS) is a multisystemic disorder that includes accelerated aging caused by trisomy 21. In particular, overexpression of cystathionine-β-synthase (CBS) is linked to excess intracellular hydrogen sulfide (HS), a mitochondrial toxin at higher concentrations, which impairs cellular viability. Concurrent overexpression of superoxide dismutase 1 (SOD1) may increase oxidative stress by generating excess hydrogen peroxide (HO) while also mitigating the toxic HS burden via a non-canonical sulfide-oxidizing mechanism.

Article Synopsis
- People with Down syndrome face a higher risk of early onset Alzheimer's, prompting a study to pinpoint issues in their healthcare from the perspectives of providers, patients, and facility staff.
- The study involved 14 interviews revealing that medical providers often lack knowledge and experience in treating individuals with Down syndrome, making dementia diagnosis particularly challenging.
- Proposed solutions include better training, caregiver involvement, medication reviews, and alternative treatment methods, which will be used to inform future health policy aimed at improving care for this population.
Trisomy 13, home health-care and multidisciplinary approach: Case report.

Article Synopsis
- The objective of the text is to highlight the importance of recognizing and addressing Patau's syndrome through a case study of a 2-year-old patient receiving extensive Home Care services.
- The case describes a female patient who underwent a cesarean delivery due to restricted growth and was diagnosed with Patau's syndrome at birth, yet has survived longer than expected with specialized home-based care.
- The comments emphasize that a multidisciplinary care approach, including medical and psychological support, has led to positive outcomes and stresses the importance of support networks for families dealing with similar illnesses.*

Article Synopsis
- Down syndrome (DS) is a common condition caused by an extra chromosome 21, leading to various health issues, including skin problems that are often overlooked by healthcare providers.
- This study examined 100 individuals with DS and 100 matched controls to identify skin conditions prevalent in DS and highlighted the need for routine skin evaluations during health check-ups.
- Results showed a high occurrence of skin-related issues in the DS group, such as dry skin and hair thinning, and indicated significant differences in the presence of certain skin infections and conditions compared to the control group.
