We present a case of multiple trichoepithelioma associated with milia. A 12-year-old girl developed symmetrically distributed, numerous, skin-colored papules on her face, some of which were studded with milia-like whitish materials. Histopathological findings of these lesions revealed the typical findings of trichoepitheliomas with overlying milia in the upper dermis.

Surgical advance on the general surgical department as minimal access procedure was changed into the laparoscopic cholecystectomy from open cholecystectomy for treatment of cholelithiasis. Laparoscopic cholecystectomy is far less invasive, less painful, less expensive, less complicative, high cosmetic and high eonservative procedure, and reduced hospitalization than open surgery.

BACKGROUND: Post-herpetic neuralgia is the most serious one of herpes zoster complications and its incidence becomes higher as the age of the patient increases. Nevertheless, besides considering the age and onset time of treatment, there is no more objective factor estimating the prognosis of post- herpetic neuralgia. OBJECTIVE: The aim of this study is to understand the progression of herpes zoster and estimate the prognosis of post-herpetic neuralgia by practicing electrodiagnostic tests to patients with herpes zoster. METHODS: We evaluated the pain scales in 26 patients with herpes zoster on the first visit and 2 months later. We also performed electrodiagnostic tests, more objective and reproducible methods, including somatosensory evoked potentials and motor nerve conduction studies on both the involved and uninvolved sites of 32 lesions in 26 patients with herpes zoster, and then compared the results with the change of pain scales. RESULTS: 1. The pain category scale and visual analogue scale on the second examination were significantly decreased compared with those on the first examination (P<0.05). 2. Latencies of intercostal somatosensory evoked potentials recorded on scalp and spine were significantly delayed in involved sides compared with those in uninvolved sides (P<0.05). 3. In the latencies and conduction velocities of motor nerve conduction studies, no significant differences were seen between involved sides and uninvolved sides. 4. On the second examinataion, latency differences of somatosensory evoked potentials were significantly improved compared with those on the first examination (P<0.05). 5. Among the various somatosensory evoked potentials parameters, P1 latency difference of cortical somatosensory evoked potentials between involved and uninvolved sides correlated significantly with pain category scale ard visual analogue scale on second examination (r=0.48, P<0.05; r =0.51, P<0.05, respectively). N1 latency difference of spinal somatosensory evoked potentials between involved and uninvolved sides correlated significantly with a visual analoge scale on the first examination and pain category scale on the second examination (r=0.61, P<0.05; r=0.78, P<0.05, respectively). CONCLUSION: Intercostal somatosensory evoked potentials can be a useful and reliable technique to predict the development and severity of post-herpetic neuralgia.

Background: Limited access to medical services causes problems in patients’ health and life. Also, hospital closures cause concentration towards general hospitals, which leads to worsening National Health Insurance finance. Therefore, hospital closure is an important topic to be analyzed. Methods: This paper analyzed the factors that affect hospital closures using survival analysis with the data of 970 hospitals opened between 2010 and 2019 in Korea. The number of medical personnel, hospital rooms, sickbeds, and medical departments were used as explanatory variables. Results: The number of medical personnel and hospital rooms increased the survival probability while the number of sickbeds and medical departments decrease the survival probability. Conclusion The results suggest that hospitals have economies of scale and diseconomies of scope in management.

Hypertrichosis is an overgrowth of hair not localized to the anclro en dependent areas of the skin. It may be congenital or acquired, localized or generalized localized hypertrichosis may occur in some types of pigrnentary nevi, chronic inflammation or irration, topical application of androgen or steroid, & localized myxedema. We report herein three i:ases of unilateral localized hypertrichosis with or without a brownish hyperpigmented patch developing on the face of a male adol scent. There are no known cau:,es of localized hyper trichosis. Histopath logically, it is characterized by increased melaniii pigment in the basal layer of the epidermis & enlarged hair follicles containing coarser liair. Electron microscopic findings show normal size & number of melanosomes in both mela nocytes & keratinocytes. Our cases differ frorn BecLers nevus in both clinical & histopatholcgic characteristics.

Cutis verticis gyrata(CVG) is an unusual conformation of the scap characterized by the presence of folds and furrows due to thickening of the corium and the subutlneous tissue. In sccordance with etiological factor and associated findings, CVG occurs as primarary disease or secondary to a variety of local or systemic diseases. Cerebriform intradermal nevus(CIN) is a cause of CVG that can usually be recognized clinically and for a certainty histologically. We report two cases of CVG due to CIN. Not only did they have CVG due to CIN on the scalp, but also they had associated congenital nevi on the face and whole boispy, respectively.

A 61-year-old woman, who had been treated by acupuncture on the glabellar region due to frontal headache ten days ago, had a rapidly growing tumor on that region. Histopathologically, the tumor was shown to be a central crater filled with eosinophilic keratin & a marginal but-tress formed by invagination of the epidermis. According to clinical & histopatholpgical findings, we can easily diagnose our case as solitary keratoacanthoma. As shown in our case, we think that acupuncture should be counted as one of the causative factors in the development of solitary keratoacanthoma.

Bilateral segmental neurofibromatosis is a rare disease characterized by bilateral neurofibromas, with or without pigmented lesion, or unilateral neurofibromas with contralateral pigmented lesion, limited to a body segment. Partial unilateral lentiginosis is characterized by numerous lentigines localized to a body segment, often corresponding to one or more dermatome. Bilateral segmental neurofibromatosis combined with partial unilateral lentiginosis is very rare, and to our knowledge, only 2 cases have been reported in English literature. We herein report another case of bilateral segmental neurofibromatosis with partial unilateral lentiginosis in a 46-year-old woman.
