Female Genital Hair-Thread Tourniquet Syndrome: A Case Report and Literature Systematic Review.

"Hair-thread tourniquet syndrome" (HTTS) describes the condition in which fibers of hair or thread wrap around an appendage (ie, toes, fingers, genital structures, tongue, uvula, and neck), eventually causing ischemia and tissue necrosis. To date, few cases of female genitalia HTTS have been described. We report a case of female genitalia HTTS in a 5-year-old girl and report the state of the art by systematically reviewing all existing evidence about female genital HTTS. A total of 29 studies, describing a total of 34 patients, were identified. The presence of a hair-thread wrapping genitalia should be suspected in prepubertal girls complaining of genital pain associated with vulvar/vaginal swelling, wide-based gait, and voiding symptoms. Genital examination disclosing an extremely tender, swollen, and erythematous lesion on the clitoris or labia minora encircled by a hair confirms the diagnosis. The aim of the management is to remove the hair-thread in the shortest time possible, with the use of forceps, scissors, or scalpels, and this is often performed under sedation/anesthesia because of the patient's pain reaction. When the hair-thread is difficult to find or when the lesion is necrotic, excision of the lesion itself can be the only option. Complications include partial or total amputation because of tissue necrosis and recurrence.

Evaluation of hemodynamics in healthy term neonates using ultrasonic cardiac output monitor.

BACKGROUND: Transition from intrauterine to extrauterine life is a critical phase during which several changes occur in cardiovascular system. In clinical practice, it is important to have a method that allows an easy, rapid and precise evaluation of hemodynamic status of a newborn for clinical management. We here propose a rapid, broadly applicable method to monitor cardiovascular function using ultrasonic cardiac output monitoring (USCOM). METHODS: We here present data obtained from a cohort of healthy term newborns (n = 43) born by programmed cesarean section at Fondazione MBBM, Ospedale San Gerardo. Measurements were performed during the first hour of life, then at 6 + 2, at 12-24, and 48 h of life. We performed a screening echocardiography to identify a patent duct at 24 h and, if patent, it was repeated at 48 h of life. RESULTS: We show that physiologically, during the first 48 h of life, blood pressure and systemic vascular resistance gradually increase, while there is a concomitant reduction in stroke volume, cardiac output, and cardiac index. The presence of patent ductus arteriosus significantly reduces cardiac output (p = 0.006) and stroke volume (p = 0.023). Furthermore, newborns born at 37 weeks of gestational age display significantly lower cardiac output (p < 0.001), cardiac index (p = 0.045) and stroke volume (p < 0.001) compared to newborns born at 38 and ≥ 39 weeks. Finally, birth-weight (whether adequate, small or large for gestational age) significantly affects blood pressure (p = 0.0349), stroke volume (p < 0.0001), cardiac output (p < 0.0001) and cardiac index (p = 0.0004). In particular, LGA infants display a transient increase in cardiac index, cardiac output and stroke volume up to 24 h of life; showing a different behavior from AGA and SGA infants. CONCLUSIONS: Compared to previous studies, we expanded measurements to longer time-points and we analyzed the impact of commonly used clinical variables on hemodynamics during transition phase thus making our data clinically applicable in daily routine. We calculate reference values for each population, which can be of clinical relevance for quick bedside evaluation in neonatal intensive care unit.
