Menstrual Cycle Patterns and Irregularities in Hired Latinx Child Farmworkers.

Purpose: This study identifies the menstrual cycle irregularities of Latinx child and adolescent farmworkers.

Methods: Child and adolescent farmworkers aged 13 to 20 years completed questionnaires about menstrual cycle patterns in 2019, and wore silicone passive collection wristbands for pesticide detection in 2018. Menstrual cycle irregularities were determined from the American College of Obstetricians and Gynecologists committee opinion.

[Comparative study of tears protein composition in patients after photorefractive keratectomy and laser specialized keratomileusis].

Changes in the protein spectrum of the lacrimal fluid, resultant from refraction ocular surgery (photorefraction keratectomy, PRK, and laser specialized keratomileusis, LASIK) were evaluated. Lacrimal fluid was collected before operation and in various terms after it in 28 patients (48 eyes) subjected to PRK and in 34 patients (59 eyes) subjected to LASIK. Biochemical analysis of the lacrimal fluid was performed on a mass spectrometer.

Tear production after unilateral removal of the main lacrimal gland in squirrel monkeys.

Objective: To study the effects of lacrimal gland removal on basal and reflex tear production and on the ocular surface in the squirrel monkey.

Methods: Unilateral main lacrimal gland removal in 6 squirrel monkeys was followed by Schirmer testing, slit-lamp examination with fluorescein, and collection of basal and reflex (stimulated) tears for analysis of tear protein spectra between 0 and 20 kd, as well as histological evaluation.

Results: Schirmer test results showed an 80% decrease in basal tears and a 90% decrease in reflex tears during week 1, and a 32.
