4.Management of carpal bone fractures other than the scaphoid: a narrative review

While scaphoid injuries are the most common carpal bone injuries, injuries to other carpal bones also occur frequently, accounting for about 40% of all carpal bone injuries. These non-scaphoid injuries are often complex, typically resulting from high-energy trauma and involving damage to two or more carpal bones or surrounding soft tissues. The carpus is a complex joint with eight carpal bones, making an accurate initial diagnosis challenging in many cases. A missed diagnosis or delayed treatment can lead to complications such as malunion, nonunion, avascular necrosis, and carpal instability. These complications can result in arthritis, neurovascular compression, and tendon rupture, causing chronic pain and functional impairment of the wrist joint. Therefore, careful attention to diagnosis and treatment is essential at the time of injury.

Microsatellites are short nucleotide repeat sequences present throughout the human genome. Alterations of microsatellites, comprising extra or missing copies of these se quences, have been termed microsatellite instability(MSI, genetic instability, replication errors, RER(+) phenotype). To date, at least four genes involved in DNA mismatch repair, hMSH2, hMLH1, hPMS1 and hPMS2, are thought to account for the observation of microsatellite instability in tumor from Hereditary nonpolyposis colorectal cancer (HNPCC) patients. The genetic defect responsible for the MIN+ phenotype in sporadic colorectal cancer, however, has yet to be clearly delineated. The purpose of this study was to determine the presence of MSI in sporadic cancer and to correlate its occurrence with clinicopathological parameters, we have studied six microsatellite loci by use of polymerase chain reaction amplification and denaturing polyacrylamide gel electrophoresis. We found that 20%(9 of 46 cases) sporadic colorectal cancers showed RER at two or several loci(RER+). Microsatellite instability was associated with location of the tumor in the proximal colon 66%(6 of 9 cases) and with poorly differentiated tumor phenotype 56%(5 of 9 cases). In order to better understand the role of somatic alterations within hMSH2 in the process of colorectal tumorigenesis, we examined the most conserved regions(codon 598~789) of this gene in nine patients with MIN spotadic colorectal cancer. 6 patient of RER(+) colorectal ca. patients had a polymorphism which was a T to C base change in the intron sequence at -6 position of the splice acceptor site at the 5'end of exon 13. This particular sequence variation is a polymorphism rather than a mutation which increase cancer susceptability. These data suggest that the genetic instability is detect ed in some colorectal cancers and play an important role in the pathogenesis of sporadic colorectal cancer.

The effect of 0.25% and 0.5% Timolol on intraocular pressure and concentration in aqueous humor was studied after topical instillation in the white rabbit. The intraocular pressure was measured with pneuma tonometer and the Timolol concentration in aqueous humor was measured with High Preformance Liquid Chromatograph after fine needle aspiration of aqueous humor at various time intervals. The results were as follows; 1. The percentage reduction of intraocular pressure increased with time and reached a peak after 3 hours. 2. The concentration of Timolol in aqueous humor increased with time and reached a peak after 3 hours. 3. There was close correlation between intraocular pressure and Timolol concentration in aqueous humor.

10.How and on whom to perform uterine-preserving surgery for uterine prolapse
Obstetrics & Gynecology Science 2022;65(4):317-324
The demand for uterine preservation in pelvic reconstructive surgery for uterovaginal prolapse is steadily increasing, and several procedures have been introduced, such as sacrospinous hysteropexy, uterosacral hysteropexy, sacrohysteropexy, and hysteropectopexy. However, the benefits and risks of uterine-preserving surgeries are not well understood. This review discusses the current evidence surrounding uterine-preserving surgery for uterovaginal prolapse repair. This may help surgeons and patients have a balanced discussion on how and on whom to perform uterine-preserving surgery.
