Telecanthus is a common symptom accompanied by Waardenburg syndrome, a rare genetic disorder. The optimal surgery for telecanthus correction is still debated. A 28-year-old patient with Waardenburg syndrome underwent transnasal wiring canthopexy using a Y-V epicanthoplasty for telecanthus correction. A Mini-Monoka stent was used to prevent damage to the lacrimal apparatus. The intercanthal distance decreased from 50 mm to 43.2 mm. The easily designed Y-V epicanthoplasty incision provides sufficient operative field for oblique transnasal wiring, which is effective in properly positioning the medial canthal tendon. It has minimal scarring resulting in satisfactory cosmetic outcomes.

Verruca plana is a cutaneous infection caused by the human papilloma virus. Although various treatment methods are currently available, most have limitations due to the risk of complications such as hyperpigmentation, edema, and scarring. Moreover, as the infection tends to spread easily, new verrucae can potentially develop, and treatment procedure times tend to be lengthy. Thus, novel treatment methods are required. The 2790-nm wavelength erbium:yttrium-scandium-gallium-garnet (Er:YSGG) laser is a superficial resurfacing laser. Here, we present a case of a 25-year-old woman with multiple verrucae treated using a 2790-nm Er:YSGG laser. Compared to traditional methods, this novel laser is convenient, produces better cosmetic outcomes, and is less time-consuming; it is therefore suitable for the treatment of facial verruca plana.

The picosecond laser has been widely used to remove tattoos, and improve wrinkles, acne scarring, and pigmented scars. This study was performed to investigate the efficacy and safety of a 1,064-nm fractional picosecond laser treatment for depressed traumatic scars. A total of twenty Korean patients with depressed scars were treated with a 1,064-nm fractional picosecond laser at a two-week interval with a spot size of 3 mm, fluence of 3.5 to 5.5 J/cm², and frequency of 2 Hz with a combination of microlens arrays. At 4 weeks after the final treatment, there was a statistically significant improvement in the modified Vancouver Scar Scale (mVSS) and the patient satisfaction score without any significant complication. A 1,064-nm fractional picosecond laser treatment is a safe and effective method to improve traumatic wound scars with depression.

There is growing interest in minimizing postoperative scarring after a thyroidectomy. Among the many treatment types, laser therapy, especially picosecond-domain laser therapy, is accepted as a standard method. In the present case, a patient with a pigmented, contracted scar was treated using the combination of a picosecond laser and ablative fractional (AF) CO₂ laser. After 15 sessions of 1,064-nm picosecond with micro lens array (MLA) and AF CO₂ laser application, the patient showed significant improvement in their pigmented lesions and scar contracture with no noticeable side effects for 16 months. These results suggest that a combination of picosecond laser with MLA and AF CO₂ laser can treat pigmented, contracted scars safely and effectively.

The perioral region, which is one of the most conspicuous parts of the face, plays a significant role in interpersonal communication. However, the perioral region is highly susceptible to scarring and pigmentation and is difficult to treat. The causes of perioral hyperpigmentation are many, including physiologic reasons, systemic diseases, drugs, and infections. In the treatment of perioral hyperpigmentation, the cause of the disease must be diagnosed first. Management includes lifestyle modifications such as reducing the UVA exposure time, use of topical treatments including hydroquinone and retinoids, and physical therapy including laser therapy. We report a case of perioral hyperpigmentation treated with 1,064-nm Q-switched neodymium:yttrium-aluminum-garnet laser toning.

Although modern medicine has made great strides in the management of burn injuries, associated complications such as pain, infection, dyspigmentation, and scarring have yet to be fully dealt with. Although skin grafting and meshing are routinely performed on burn patients, this method poses a risk for adverse effects. Activated autologous platelet-rich plasma (aaPRP), which is increasingly used in the field of plastic surgery, contains growth factors beneficial for wound regeneration. Seven cases of burns with varying severity and conditions that were treated with intralesional subcutaneous injection and intravenous aaPRP are presented and discussed herein. This case series indicates that subcutaneous and intravenous aaPRP is a safe procedure with the potential to be an alternative when skin grafting cannot be done or as an adjunct treatment to skin grafting.

Reconstruction of the upper lateral lip subunit is challenging, and use of several classical local flaps have been previously reported. However, these methods have drawbacks such as visible scarring, anatomic distortion, and functional disability. To obtain satisfactory results, preservation of perioral function is important. We report a case of functional upper lip reconstruction after tumor resection using a reverse facial-submental artery island flap with a reinnervated anterior belly of the digastric muscle (ABDM) without sacrificing the perioral structure. A 73-year-old man presented with basal cell carcinoma on the left upper lip which was widely excised, including the orbicularis oris muscle. The remaining 4 cm × 3.5 cm defect was reconstructed using a reverse facial-submental artery island flap with ipsilateral ABDM. The motor nerve of the ABDM was sutured with the stump of the buccal branch of the ipsilateral facial nerve. The postoperative course was uneventful, and good functional and esthetic recovery were observed at 12-month follow-up. This procedure may be an alternative option for reconstruction of lateral upper lip defects.

Patients with vesicoureteral reflux (VUR), the retrograde flow of urine from the bladder to the kidney, are known to experience renal scarring; this results in the worsening of renal function. Reflux nephropathy is a cause of chronic kidney disease, and VUR has also been observed in dialysis patients. VUR is a major underlying precursor condition of urinary tract infection (UTI) and is sometimes accompanied by hydronephrosis. However, there are no guidelines for the management of UTI due to VUR-associated hydronephrosis in patients with end-stage kidney disease. Herein, we report a case of UTI caused by VUR-associated hydronephrosis in a dialysis patient treated with percutaneous nephrostomy.

The gut microbiome is widely recognized as a dynamic organ with a profound influence on human physiology and pathology. Extensive epidemiological and longitudinal cohort studies have provided compelling evidence that disruptions in the early-life microbiome can have long-lasting health implications. Various factors before, during, and after birth contribute to shaping the composition and function of the neonatal and infant microbiome. While these alterations can be partially restored over time, metabolic phenotypes may persist, necessitating research to identify the critical period for early intervention to achieve phenotypic recovery beyond microbiome composition. In this review, we provide current understanding of changes in the gut microbiota throughout life and the various factors affecting these changes. Specifically, we highlight the profound impact of early-life gut microbiota disruption on the development of diseases later in life and discuss perspectives on efforts to recover from such disruptions.

Burns are one of the most extensive injuries of soft tissues as well as skin, occasionally resulting in extensive, deep wounds and death. Burn wounds can lead to severe physical and psychological distress because of excessive scarring and skin contractures. Treatment of burn wounds has always been a challenging problem and many different methods have been used to treat such injuries. We report here on treating a patient with a burn wound using 830-nm light emitting diode (LED) phototherapy combined with epidermal growth factor (EGF) solution. After five daily sessions of LED with EGF solution treatment, the patient demonstrated nearly complete improvement with no remarkable side effects. We suggest that LED phototherapy combined with EGF solution could be an effective and safe treatment option for treating burn wounds.
