BACKGROUND: The need for dermatological consultations for hospitalized patients has gradually increased and there are a number of dermatoses caused by underlying psychological conditions. However, the data regarding the analyses of these consultations for psychiatric inpatients are limited. OBJECTIVE: To analyze the demographics and the type of dermatoses among inpatients with primary psychiatric diseases. METHODS: We retrospectively reviewed 581 consultation reports for inpatients referred by the Department of Psychiatry between January 1, 2009 and December 31, 2014. RESULTS: The proportion of the consulted patients from the Department of Psychiatry was 25.9% (331 consulted inpatients/1279 psychiatric inpatients). The most common age group was the 40~49 year-old group (19.3%) and the male to female ratio was 1:1.14. There were no remarkable findings regarding the annual or seasonal distribution. According to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), the most common underlying psychiatric disorders were mood disorders (41.0%), followed by schizophrenia and other psychotic disorders (25.0%), and substance-related disorders (12.1%). The most frequent skin disorders were eczematous dermatoses (34.6%) and infectious dermatoses (32.2%); dermatomycosis (20.8%) was especially common. The most common reasons for consultation were new-onset dermatologic problems (68.5%), followed by persistence or aggravation of pre-existing dermatologic disorders (28.7%). CONCLUSION: This study reports the dermatologic characteristics of psychiatric inpatients. We conclude that dermatologists and psychiatrists need to be concerned about the education and continuous management of various skin diseases in psychiatric patients.

BACKGROUND: Dermoscopy is a real-time, noninvasive technique that increases the diagnostic accuracy of clinical evaluation by the dermatologist. Characterization of facial actinic keratosis via dermoscopy is valuable in guiding the dermatologist in the differential diagnosis of facial skin lesions. To our knowledge, dermoscopic evaluation of actinic keratosis has not yet been reported in Korean literature. OBJECTIVE: The purpose of this study was to investigate the dermoscopic features of facial actinic keratosis in Koreans. METHODS: We examined 60 patients with facial actinic keratosis using dermoscopy. We determined the frequency of specific features revealed by dermoscopy across the Korean patient population and compared our results with those of other published studies. RESULTS: A total of 67 facial actinic keratoses were observed in 60 patients. The common features of non-pigmented actinic keratoses revealed by dermoscopy were a red pseudo-network (66%), white-to-yellow surface scales (48.9%), linear wavy vessels (38.3%), and targetoid hair follicles (42.6%). The common features of pigmented actinic keratoses revealed by dermoscopy were slate-grey dots (55%) and globules (30%), annular-granular pattern (35%), a brown-to-gray pseudo-network (40%), and targetoid hair follicles (30%). The frequency of specific features revealed by dermoscopy across the analyzed patient population was not significantly different from that reported in other studies, except for rhomboidal structures (5%), which was lower in Koreans than in other populations (35.8%, p<0.05). The frequency of dermoscopic features was different according to histopathologic subtypes (hypertrophic, atrophic, bowenoid, acantholytic actinic keratosis). CONCLUSION: Dermoscopy revealed specific features of facial actinic keratosis that can be utilized to evaluate and diagnose facial skin lesions.

Adult-onset Still's disease (AOSD) is an uncommon disorder characterized by fever, polyarthralgia, elevated white blood cell count, and maculopapular rash, the histologic features of which have not been well known. A 54-year-old woman presented with fever, arthritis, and persistent pruritic lichenified rash. These cutaneous lesions showed unique histological features such as dyskeratosis with a peculiar, distinctive distribution in the upper epidermis and cornified layers with hyperkeratosis. In addition, dermal mucin deposition was increased, with inflammation and minimal fibroblast proliferation. The patient was diagnosed with AOSD according to the diagnostic criteria of Yamaguchi. Herein, we present an atypical form of AOSD showing distinctive clinical and pathological manifestations.

Post-menopausal women experience variable biological and psychological changes. The effect of reduced levels of estrogen can effect on post-menopausal depression. Estrogen triggers physiological responses by binding to the estrogen receptor (ER). Two subtypes of ER, ERa and ERb are now known. We investigated the significance of ERa and ERb polymorphisms and post-menopasal depression in this study. Forty three women with post-menopausal depression and 63 post-menopausal women without depression as normal controls were recruited. Polymerase chain reaction-restriction fragment length polymorphism method was used to investigate genotypes of ERa and ERb polymorphisms. Genotypes of PvuII and XbaI polymorphism of ERa receptor were significantly different in patients with post-menopausal depression comparing with controls. Genotypes of ERb did not show association with post-menopausal depression. Our study showed that ERa receptor polymorphism had an association with depression in post-menopausal women. It suggests that investigation of ER genes and their functions might be important for understanding pathophysilogical mechanism of post-menopausal depression.

Poroid hidradenoma is a benign tumor that is classified as a poroid neoplasm, and is so called because of its morphology, which is intermediate between the cytological features of a poroid neoplasm (poroid and cuticular cells) and the architectural features of a hidradenoma (solid and cystic areas, and tumor cells restricted to the dermis). As these tumors are cystic and superficially located, fine needle aspiration cytology has been useful, but the diagnosis relies on the histological examination. A 79-year-old woman presented with a solitary walnut-sized, soft, tender, reddish-to-bluish nodular lesion that had been enlarging steadily over a period of two years. Histopathologic examination of the cutaneous lesion showed a well-demarcated tumor composed of poroid and cuticular cells in the dermis not connected to the overlying epidermis, consistent with poroid hidradenoma. Herein, we present a rare case of poroid hidradenoma arising in an unusual location.

BACKGROUND: There were two occurrences of typhoon and the floods in Korea from early to late September, 2000. The Korean Combat Police and policemen participated in cleaning activities at the flooded area. Leptospirosis broke out among these participants. This study describes the epidemiological and clinical characteristics of leptospirosis patients among policemen. METHODS: Of 16,750 individuals involved, 3,752 subjected to passive hemagglutination antibody (PHA) test at the Regional Health Care Units or the National Police Hospital. With 1 case of dead plus 12 cases which were turned out to be seropositive by PHA test and confirmed by microagglutination (MA) test, epidemiological and clinical characteristics were studied by questionnaire survey, laboratory test, and history of treatment while being hospitalized. RESULTS: The seropositive rate of leptospira antibody was 0.3% (12/3,752). All 12 seropositives were bare-footed while working at the flooded area and of these, 8 patients (67%) were noticed abrasions either on hand or feet. However, no statistically significant correlation was found between the duration of outdoor activity and the seropositive rate (r=-0.46, p=0.36). There were clinical difference among patients who has the same serotype of leptospirosis, physical conditions, circumstance and the same work area. Two abnormal EKG results are present, the one who complained of chest pain is myocardial ischemia and the other who didn't complain of any symptoms is sinus pause. Correlation between the febrile period before and the duration of fever after the use of antibiotics was estimated as; febrile period after antibiotics use = 0.102804 + 0.995327 x febrile period before antibiotics use (p=0.058). CONCLUSION: When leptospirosis is related to group activities, it is possible to educate in advance and to manage systematically afterwards, it may prevent the occurrence of leptospirosis or the related complications.

Trazodone has favorable pharmacological profiles with a few anticholinergic effects and cardiac conduction abnormailties. Thus it is more acceptable in geriatric population than tricyclic antidepressant (TCA) especially in patients with combined medical conditions, although attention should be paid to monitor its well-known side effects, orthostatic hypotension and priapism. Unlike expected favorable profiles, we had experienced a case of increased intraocular pressure (IOP) shortly after lowdose trazodone treatment in a known-glaucoma patient.
