AI Article Synopsis

  • - Mastering manual small-incision cataract surgery (MSICS) is challenging for beginner surgeons, particularly in creating a proper scleral tunnel and making keratome entries.
  • - Many surgeons experience issues like premature entry and iris prolapse, often due to improper techniques, with premature entry being more associated with crescent blade tunnel construction.
  • - The novel trypan blue dye-assisted tunnel staining (TBTS) technique aids in clear tunnel visualization, potentially decreasing the risk of premature entry when using a keratome.

Article Abstract

Mastering manual small-incision cataract surgery (MSICS) for beginner surgeons is difficult. In the initial days of residency or training, surgeons struggle to make a proper scleral tunnel and keratome entry. It commonly results in premature entry and iris prolapse. Most of the literature has shed light on premature entry during tunnel construction by a crescent blade, whereas a significant majority of iris prolapse happens due to improper keratome entry. This novel trypan blue dye-assisted tunnel staining (TBTS) technique helps in proper tunnel demarcation which can reduce the incidence of premature entry with a keratome.

Research Findings: Temperament, which can be assessed as early as three months, is associated with school readiness and later academic achievement in children born full term. Although children born preterm demonstrate a dysregulated temperament and are at significant risk for lower school readiness, we found no studies investigating whether early temperament is associated with school readiness in this at-risk population. Investigating whether temperament is a precursor of academic risk in preterm children can facilitate early identification and possible intervention efforts.

Karyotype instability in the germline leads to infertility. Unlike the female germline, the male germline continuously produces fertile sperm throughout life. Here we present a molecular network responsible for maintaining karyotype stability in the male mouse germline.

Objective: To discuss the elbow skin fold extension line in Kirschner wire internal fixation of extended supracondylar humeral fractures in children.

Methods: The clinical data of 58 children with extended supracondylar fractures of the humerus who met the selection criteria between August 2021 and July 2024 were retrospectively analyzed. In 28 cases, needle placement of medial epicondyle of humerus was performed with the assistance of the elbow skin fold extension line (study group), and 30 cases were assisted by routine touch of the medial epicondyle of the humerus (control group).

Neurodegenerative diseases are a group of disorders characterized by progressive degeneration or death of neurons. The complexity of clinical symptoms and irreversibility of disease progression significantly affects individual lives, leading to premature mortality. The prevalence of neurodegenerative diseases keeps increasing, yet the specific pathogenic mechanisms remain incompletely understood and effective treatment strategies are lacking.

The twin reversed arterial perfusion (TRAP) sequence is a rare complication associated with monochorionic twins. It is characterized by blood flow from the umbilical artery of the normal (pump) twin to the umbilical artery of the abnormal (acardiac) twin via artery-to-artery anastomosis. This condition is associated with 100% mortality in the acardiac twin and a high rate of perinatal morbidity and mortality in the pump twin, primarily due to intrauterine hypoxic injury, heart failure, and prematurity.
