Alopecia Associated With Birth Injury

Localized hair loss in infancy: a review

PURPOSE OF REVIEW

The current review will address the different causes of localized hair loss in infancy. The data presented here will provide clinicians with the latest understanding of different disorders leading to localized hair loss and will provide recommendations for further management of infants who present with alopecia.

RECENT FINDINGS

Localized hair loss in infancy is common, but its underlying causes vary greatly. Alopecia in infants can be categorized into congenital, genetic, inflammatory, mechanical, and physiologic causes. Decisions regarding further management are complex, as they often involve not only cosmetic concerns, but also work-up of possible systemic medical issues related to hair loss.

SUMMARY

Clinicians must be able to distinguish between the different causes of infantile hair loss so that appropriate work-up and further management can be pursued. Factors such as physical appearance, timing of presentation, dermoscopic exam, histopathology, and associated systemic features can help lead clinicians to the correct diagnosis in the case of an infant with localized alopecia.

Neonatal Alopecia Due to Birth Trauma: Case Report and Trichoscopic Findings

A 4-day-old boy was referred for evaluation of an oval patch of occipital alopecia associated with caput succedaneum and ipsilateral eyelid ecchymoses. Based on the history of a prolonged, difficult labor with vacuum-assisted delivery, the diagnosis of neonatal alopecia associated with birth trauma was made. Trichoscopy showed purple dots corresponding to blood extravasation and follicular ostia. We also review the trichoscopic differential diagnosis of focal neonatal alopecia.

Tissue expansion and latissimus dorsi transfer for arm-thorax synechia reconstruction

Inadequate treatment of severe burn injury often results in scar contractures with subsequent functional impairment and cosmetic deformities depending on the body area involved. Arm-thorax synechia is a rare but devastating complication of burns. The authors report a case of a 17-year-old boy with subtotal arm-thorax synechia, secondary to burn contracture. Reconstruction was accomplished, in two stages, with the use of tissue expanders and a latissimus dorsi muscle flap. The postoperative course was uneventful in both stages, with complete survival of both the expanded skin and the muscle flap. Early initiation of intensive rehabilitation resulted in excellent functional outcome, while significant aesthetic improvement was also ensured. In conclusion, the combined use of tissue expansion and latissimus dorsi transfer may prove to be a very good option in the treatment of complex postburn axillary contractures. The main advantages of the suggested method are the best quality of skin provided by tissue expansion and the safe coverage of any vital structures exposed with the use of the muscle flap.

Iatrogenic skin injury in the neonatal intensive care unit

Although neonatal care has become more and more meticulous with significant changes in technology in the neonatal intensive care unit (NICU) in the past 50 years, iatrogenic cutaneous injuries continue to occur. Although the incidence of severe injuries is decreasing because the more difficult procedures are being replaced by improved techniques, skin injuries have not yet been completely eliminated. However, the nature and causes of cutaneous injuries have changed, and the injuries are frequent but generally minor. The major risk factors are low birth weight, gestational age, length of stay, a central venous line, mechanical ventilation, and support with continuous positive airway pressure. The rate of iatrogenic events is about 57% at gestational ages of 24-27 weeks, compared with 3% at term. There are no current comprehensive reviews of iatrogenic cutaneous injury. The purpose of this review is to describe the iatrogenic cutaneous injuries that may occur in the newborns as a consequence of perinatal and postnatal medical procedures. With increased survival of extremely-low-birth-weight (ELBW) infants and changing modes of management in the NICU, neonatologists must make every effort to recognize injuries and prevent their occurrence in the NICU.

Head trauma after instrumental births

Instrumental vaginal delivery involves the use of the vacuum extractor or obstetric forceps to facilitate delivery of the fetus. It is associated with substantial risk of head injury, including hemorrhage, fractures, and, rarely, brain damage or fetal death. This review article describes the different types, etiology, pathophysiology, risk factors, and clinical features of head trauma after instrumental birth, along with their management and prevention strategies.
