Congenital melanocytic nevus is a hamartoma derived from the neural crest that is present at birth. Regression following surgical excision with an apparent halo phenomenon through suture lines has never been reported. A nine-year-old boy presented with a solitary symmetric, oval-shaped, blackish pigmented patch on his right forearm.He reported increasing size of the lesion with no other subjective symptoms. Histological examination of the first excisional biopsy revealed congenital melanocytic nevus, and serial excisions were planned. Interestingly, at the second visit at 18 months after the first biopsy, the size of the congenital melanocytic nevus was reduced with a peripheral whitish halo. Linear regression through suture lines and a peripheral halo was observed after the second and third serial excisions. The mechanism of the halo phenomenon remains elusive but is suggested theorized to be caused by destruction of melanocytes by immune responses of autoantibodies or cytotoxic T cells.

Background:
Isotretinoin is a gold standard treatment for moderate to severe acne vulgaris but is associated with cheilitis. Though moisturizing agents or petrolatum have been suggested, uncomfortable isotretinoin-induced cheilitis can disrupt treatment of acne patients. Topical tacrolimus has been used in atopic dermatitis with good safety and efficacy; however, there is no study of application of topical tacrolimus in cheilitis induced by isotretinoin.
Objective:
In this study, we aimed to describe the efficacy of topical tacrolimus 0.1% ointment on cheilitis associated with isotretinoin therapy using isotretinoin cheilitis grading scale (ICGS), investigator global assessment (IGA), and patient global assessment (PGA). We also observed the side effects of topical tacrolimus ointment.
Methods:
Fifty acne vulgaris patients with isotretinoin-induced cheilitis were randomly allocated to either topical tacrolimus or petrolatum treatment using permuted-block randomization. Patients were followed-up at 4 and 8 weeks, at which cheilitis lesions were photographed and evaluated with ICGS, IGA, and PGA.
Results:
Compared to petrolatum group, tacrolimus group had greater responses to treatment as measured by mean values of ICGS, IGA, PGA at follow-up visits. Also, the ICGS decrease was larger in the tacrolimus group compared with the petrolatum group even according to isotretinoin dose.
Conclusion
Topical tacrolimus ointment had superior efficacy in treating cheilitis induced by isotretinoin compared to petrolatum. Erythema, fissures, scales, and commissures all showed better response to tacrolimus ointment. Topical tacrolimus ointment can be administered as an effective strategy in treatment of cheilitis as a complication of isotretinoin therapy and can improve compliance of acne patients.

Background:
and Purpose Migraine is one of the most common chronic neurological diseases worldwide. Although diverse treatment regimens have been recommended, there is insufficient evidence for which treatment patterns to apply in routine clinical settings.
Methods:
We used nationwide claims data from South Korea for 2015–2021 to identify incident migraine patients with at least one prescription for migraine. Patients were categorized according to their initial treatment classes and followed up from the date of treatment initiation. Treatment regimens included prophylactic treatments (antidepressants, anticonvulsants, beta blockers, calcium-channel blockers, and renin-angiotensin-aldosterone system [RAAS] inhibitors) and acute treatments (acetaminophen, antiemetics, aspirin, ergotamine, nonsteroidal anti-inflammatory drugs [NSAIDs], opioids, and triptans). The treatment patterns of migraine were evaluated until the end of the study period, including the secular trends, prevalence, persistence, and changes in migraine treatment.
Results:
Among the 761,350 included patients who received migraine treatment, the most frequently prescribed acute treatment was an NSAID (69.9%), followed by acetaminophen (50.0%).The most-prescribed prophylactic treatment was flunarizine (36.9%), followed by propranolol (24.4%). Among the patients, 54.8% received acute treatment, 13.5% received prophylactic treatment, and 31.6% received both treatment types. However, 65.7% of the patients discontinued their treatment within 3 months. The 3-month persistence rate was highest for triptans (25.2%) among the acute treatments and for RAAS inhibitors (62.0%) among the prophylactic treatments.
Conclusions
While the prevalence rates of medication use were found to align with current migraine guidelines, frequent switching and rapid discontinuation of drugs were observed in routine clinical settings.

OBJECTIVE: To investigate phasic changes during filling cystometry that most accurately represent detrusor properties, regardless of other factors affecting detrusor contractility. METHODS: Seventy-eight patients (59 males, 19 females; mean age, 48.2 years) with spinal cord injuries were enrolled. Urodynamic studies were performed using a normal saline filling rate of 24 mL/min. We calculated bladder compliance values of the detrusor muscle in each of three filling phase intervals, which divided the filling cystometrogram into three phases referable to the cystometric capacity or maximum cystometric capacity. The three phases were sequentially delineated by reference to the pressure-volume curve reflecting bladder filling. RESULTS: Bladder compliance during the first and second phases of filling cystometry was significantly correlated with overall bladder compliance in overactive detrusors. The highest coefficient of determination (r2=0.329) was obtained during the first phase of the pressure-volume curve. Bladder compliance during all three phases was significantly correlated with overall bladder compliance of filling cystometry in underactive detrusors. However, the coefficient of determination was greatest (r2=0.529) during the first phase of filling cystometry. CONCLUSION: Phasic bladder compliance during the early filling phase (first filling phase) was the most representative assessment of overall bladder compliance during filling cystometry. Careful determination of early phase filling is important when seeking to acquire reliable urodynamic data on neurogenic bladders.
