This study suggests that the "spade sign" is a highly specific histopathologic feature of acne keloidalis, although its absence does not rule out the condition.

Dermoscopy can help diagnose tinea capitis in children by looking for comma hairs, black dots, and broken hairs with white bands.

This review discusses the development and history of follicular unit transplantation and reports no new clinical results.

The document concludes that hair transplant methods are often selected for provider convenience over patient benefit, highlighting the need for less invasive techniques and careful physician involvement for better results.

This study introduced a high-viscosity epoxy photoresist to enhance the fabrication of complex microstructures with monolithic integration and mechanical stability, enabling advancements in two-photon 3D printing for creating functional micro-mechanical devices.

This study found no significant difference in SARS-CoV2 IgG seroconversion rates between patients with immune-mediated inflammatory diseases treated with targeted immune-modulating therapies and those on conventional systemic treatments.

This study suggests that clinically apparent fragile hair in children is rarely linked to trichothiodystrophy, and the tiger-tail pattern is not wholly specific to this diagnosis.

In this study, multiple mini punch grafts significantly improved epithelialization, covering more than 90% of a large ulcer in a 6-year-old boy after eight weeks.

Light can be used to stimulate ear hair cells, improving speed and consistency over previous methods.

In this study, clinicians are advised to perform trichography regularly on Pomeranians with HCA, as significant hair abnormalities, especially TN, may affect hair quality; further research is needed to understand the underlying mechanisms and treatment options.

This review discusses pili torti, a rare hair shaft disorder, and reports no new clinical results; it emphasizes the need to investigate underlying conditions in affected individuals.

This report describes three cases of erythromelanosis follicularis faciei et colli showing significant improvement in facial telangiectasia following treatment with a 595-nm pulsed dye laser, with minimal recurrence observed during follow-up.

This study observed that platelet-rich gel for scalp defect reconstruction was more cost-effective and less painful but resulted in poorer hair growth compared to the external tissue expansion technique.

This study found that the new "A-design" punch used in FUE hair restoration surgery resulted in the smallest scar size after one month compared to sharp, blunt, and serrated punches.

This study found that a combined pattern of repigmentation was most commonly observed in vitiligo, with a new 'medium spotted' pattern proposed for areas with few hair follicles.

This case report describes a hybrid cyst in a Sprague-Dawley rat, showing both infundibular and matrical differentiation similar to different parts of normal hair follicles.

This review summarizes 57 case reports and series, noting that ultrasound is a useful, non-invasive tool to visualize subcutaneous nodules in conditions like sarcoidosis, granuloma annulare, and panniculitis, facilitating diagnosis and treatment without ionizing radiation.

This case report details a unique instance of pityriasis rubra pilaris affecting only the scalp, highlighting novel trichoscopic features and emphasizing the importance of recognizing this rare presentation for improved diagnosis and treatment.

In this study, the SAFE System for follicular unit extraction demonstrated a favorable average follicle transection rate of 6.14% and is accessible for physicians with basic technical skills, showing promise for wider adoption.

This article reports that follicular unit extraction is a minimally invasive hair restoration technique that avoids linear scarring and reduces donor-site pain compared to traditional strip harvesting methods.

This study found that torsional measurements can effectively distinguish the effects of hair care products on the cuticle versus the cortex of hair fibers, unlike tensile measurements.

This report describes an 8-year-old male with trichotillomania, confirmed by trichoscopy showing characteristic hair damage and patterns.

This article describes a concentric mini-micrografting method for extensively bald patients that achieves natural-looking hair restoration and maintains a normal appearance at all stages of treatment.

This case report describes a 50-year-old man with folliculotropic mycosis fungoides stage IB, noting trichoscopic findings like dilated follicular openings, black dots, and dystrophic hairs, which are less commonly documented in this condition, suggesting trichoscopy could aid in early diagnosis.

This review discusses the 1998 effort by 21 ISHRS hair restoration surgeons to standardize techniques for follicular unit transplantation and mini-micrografting, without reporting new clinical results.

This study developed a non-destructive X-ray fluorescence technique to quantitatively analyze elemental content in human hair and constructed a database of element concentrations in healthy Swedish, Caucasian individuals.

This study describes a novel FUE device that may perform successfully across various patient scenarios, adapting to differences in skin firmness, thickness, and hair curliness.

This study examined patients with trichostasis spinulosa and identified distinct differences in the distribution and microscopic appearances of lesions compared to keratosis pilaris and eruptive vellus hair cysts.

This case report presents a very rare instance of pilonidal sinus in the preauricular region, marking only the second known case documented in medical literature.

This pilot study employed in-vivo multiphoton microscopy to visualize pigment-producing melanocytes in vitiligo patients, aiming to enhance understanding of treatment impacts and potentially improve transplantation therapies.
