RESUMEN

BACKGROUND: Sublingual immunotherapy (SLIT) with house dust mites (HDM) preparation has recently been proven to be beneficial for treating allergic rhinitis and asthma. However, there has been no report regarding the efficacy and safety of SLIT in Korean patients with atopic dermatitis (AD). OBJECTIVE: We intended to investigate the efficacy and safety of SLIT in Korean patients with AD. METHODS: A total of 34 patients with AD and immunoglobulin E (IgE)-proven HDM sensitization (Class ≥3) were recruited. Eczema area and severity index (EASI) score, total serum IgE level, specific IgE assays to Dermatophagoides pteronyssinus, D. farinae, and adverse effects were recorded during follow-up. "Responder" was defined as a patient with ≥30% improvement in EASI score after SLIT. RESULTS: Twenty-three patients continued SLIT for 12 months or more, whereas 3 patients (8.8%) dropped out because of exacerbation of dermatitis, and 8 patients (23.5%) were lost to follow-up. The average duration of SLIT treatment was 22.4 months (range, 12~32 months). EASI scores reduced significantly after 6 months of treatment (p<0.05) compared with those at baseline. A total of 18 patients were determined to be responders to SLIT after 6 months. Total and specific IgE serum levels did not significantly reduce after SLIT. No patients experienced serious adverse events, with the exception of two patients who developed transient lip and tongue swelling. CONCLUSION: Our study demonstrated that SLIT with HDM extracts is effective and tolerable in Korean patients with AD. Further controlled long-term trials are required to reinforce the current results.

RESUMEN

Falls and fall-related injuries are common in older populations and have negative effects on quality of life and independence. Falling is also associated with increased morbidity, mortality, nursing home admission, and medical costs. Korea has experienced an extreme demographic shift with its population aging at the fastest pace among developed countries, so it is important to assess fall risks and develop interventions for high-risk populations. Guidelines for the prevention of falls were first developed by the Korean Association of Internal Medicine and the Korean Geriatrics Society. These guidelines were developed through an adaptation process as an evidence-based method; four guidelines were retrieved via systematic review and the Appraisal of Guidelines for Research and Evaluation II process, and seven recommendations were developed based on the Grades of Recommendation, Assessment, Development, and Evaluation framework. Because falls are the result of various factors, the guidelines include a multidimensional assessment and multimodal strategy. The guidelines were developed for primary physicians as well as patients and the general population. They provide detailed recommendations and concrete measures to assess risk and prevent falls among older people.

RESUMEN

OBJECTIVES: Previous studies examining the association between osteoporosis (OP) and hearing loss (HL) have shown conflicting results. The objective of the present study was to examine the association between hearing impairment and OP in postmenopausal women, using appropriate statistical analyses. METHODS: Total 1,009 participants were included in the current study. The propensity score matched (PSM) cohort was defined as the cohort including participants diagnosed with OP and participants without OP. Three statistical models were developed where model 1 was unadjusted, model 2 included age, and model 3 included age, body mass index, alcohol intake, smoking habit, diabetes mellitus, hypertension, high density lipoprotein cholesterol, triglyceride level, vitamin D, and alkaline phosphatase. RESULTS: There were 776 and 233 participants in the groups diagnosed without and with OP, respectively. For propensity score matching, 233 pairs were selected from the 776 participants without OP. In the total cohort, using statistical models 2 and 3, no significant difference in the four hearing thresholds was identified between the 2 groups. Logistic regression indicated that, in model 3, participants with OP had a 1.128 (P=0.323) increased risk HL. A significant HL risk was not observed in participants with OP. Using statistical model 3, there were no significant associations among lumbar spine or femoral neck T-scores and changes in the hearing thresholds. In the PSM cohort, statistical models also showed similar results. CONCLUSION: The current study did not demonstrate and association between bone mineral density and hearing impairment in the study population of postmenopausal Korean women.

RESUMEN

BACKGROUND: Despite efforts to treat trachyonychia, there is no promising treatment modality. OBJECTIVE: This study evaluated the efficacy and safety of calcipotriol plus betamethasone dipropionate ointment on trachyonychia. METHODS: A total of 39 patients with 432 nails affected by trachyonychia were enrolled. All patients applied calcipotriol/betamethasone ointment once daily without occlusion for 6 months. Outcome measures were assessed by physician's global assessment (degree of roughness: 0, clear; 1, mild; 2, moderate; 3, marked; 4, severe) at all time points. RESULTS: After 6 months of therapy, 98.6% (426/432) of nails showed significant clinical improvement; 4.2% were completely free from nail lesions. The mean physician global assessment score decreased significantly from 3.5 to 1.7 points (p< 0.05). No serious side effects were reported, except mild pruritus and erythema in 2 patients. CONCLUSION: This is the first study to prospectively evaluate the efficacy and safety of calcipotriol/betamethasone ointment for the treatment of trachyonychia. The results indicate topical calcipotriol/betamethasone is an effective and safe treatment for symptom improvement of trachyonychia.

RESUMEN

Erythrodermic psoriasis (EP) is a very severe variant of psoriasis whose management poses a challenge to physicians, as currently available therapies often provide unsatisfactory results. Many biologics have been used to treat chronic plaque psoriasis, the most common form of psoriasis; however, their effectiveness for EP is poorly understood. A recently developed biologic, golimumab, has been extensively studied for the treatment of moderate-to-severe active rheumatoid arthritis, psoriatic arthritis, active ankylosing spondylitis, and chronic plaque psoriasis. However, no clinical trials have been performed for EP. Here, we report the case of a 32-year-old man who presented with severe psoriasis that previously failed to respond satisfactorily to methotrexate, cyclosporine, retinoid, narrow-band ultraviolet B phototherapy, and topical agents (i.e., steroids and calcipotriol). Skin lesions worsened progressively and developed into erythroderma. Psoriatic arthritis was also detected. Conventional therapies lacked efficacy. Therefore, we administered golimumab 50 mg. The skin lesions improved significantly according to the Psoriasis Area and Severity Index score after the first administration; lesions improved further throughout the treatment course. Although additional studies are required to fully evaluate the efficacy and safety of golimumab, this agent may be an alternative treatment strategy for some patients with recalcitrant EP.

RESUMEN

BACKGROUND: Psoriatic arthritis (PsA) is chronic seronegative inflammatory arthritis that causes irreversible joint damage. Early recognition of PsA in patients with psoriasis is important for preventing physical disability and deformity. However, diagnosing PsA in a busy dermatology outpatient clinic can be difficult. OBJECTIVE: This study aimed to validate the Psoriatic Arthritis Screening and Evaluation (PASE) questionnaire for the detection of PsA in Korean patients with psoriasis. METHODS: The PASE questionnaire was prospectively given to 148 patients diagnosed with psoriasis but without a previous diagnosis of PsA. All patients underwent radiologic and laboratory examinations, and a subsequent clinical evaluation by a rheumatologist. RESULTS: Eighteen psoriasis patients (12.2%) were diagnosed with PsA according to the Classification Criteria for Psoriatic Arthritis. The PASE questionnaire scores of differed significantly between PsA and non-PsA patients. Receiver operator characteristic analysis showed an area under the curve of 0.82 (95% confidence interval: 0.72, 0.92) for PASE score. A PASE score cut-off of 37 points had a sensitivity of 77.8% and specificity of 82.3% for the diagnosis of PsA. CONCLUSION: The PASE questionnaire is a simple and convenient screening tool for detecting PsA in Korean dermatology clinics. A PASE questionnaire score of 37 points appears to be an appropriate cut-off for screening Korean psoriasis patients.

RESUMEN

The clinical course of generalized pustular psoriasis (GPP) is variable and unpredictable. Sufficient data on the clinical course of the disease has not been reported due to its rarity. To investigate the clinical features and course of GPP according to its subtypes, medical records of patients diagnosed with GPP from 2002 to 2012 at two tertiary hospitals were reviewed. The data included patient demographics, associated symptoms, aggravating factors, patterns of relapse and prognosis. Thirty-three patients with GPP were included in our study, with a mean age of 45.6 years and a male : female ratio of 1:1.2. Patients were categorized based on the following subtypes: acute GPP, 21 (63.6%); GPP of pregnancy, two (6.1%); juvenile GPP, three (9.1%); and annular GPP, seven (21.2%). In the acute GPP population, skin lesions cleared within 2 months in 11 (73.3%) patients, and six (40.0%) of these had no relapse. Severe complications, abortion or death, were observed in two patients (100.0%) with GPP of pregnancy. Nineteen (76.0%) of the GPP patients experienced persistence or relapse of skin lesions. The patterns of skin lesions upon relapse included plaques in six patients (31.6%), pustules in eight patients (42.1%), and plaques and pustules in five patients (26.3%). Among acute GPP patients, 16.7% of patients with no relapse had a history of plaque psoriasis. However, 77.8% of patients with persistence and relapse in their clinical course had a history of plaque psoriasis. In conclusion, our study presents the detailed clinical course of GPP by subtype in Korean patients.

RESUMEN

Psoriatic arthritis is a chronic inflammatory arthropathy associated with skin psoriasis. It is considered a unique arthropathy with distinct clinical and radiologic features. Up to 40% of patients with psoriasis may develop psoriatic arthritis. Psoriasis usually precedes psoriatic arthritis, so dermatologists are in a critical position for screening patients of psoriatic arthritis early in the disease course. Psoriatic arthritis may be challenging to diagnose, especially for dermatologists, because it has an insidious disease course, non-specific symptoms, and no specific biomarkers. Psoriatic arthritis is a polygenic autoimmune disorder of unknown etiology, but immunologic roles have recently been validated. In recent years, treatment modalities have rapidly advanced in the fields of psoriasis and psoriatic arthritis. Biologic agents, including TNF-α inhibitors and anti-IL12/23 agents, have shown dramatic improvement.

RESUMEN

BACKGROUND: Little information is available on effective treatments for progressive macular hypomelanosis (PMH). To our knowledge, only one case of narrowband ultraviolet B (NB-UVB) therapy as an efficient treatment for patients with PMH has been reported in the recent literature. OBJECTIVE: We aimed to investigate the clinical features of PMH in Koreans and to determine the therapeutic efficacy of NB-UVB therapy in the management of PMH. METHODS: We performed an uncontrolled prospective study designed to evaluate the usefulness of NB-UVB therapy in PMH. A total of 23 patients with PMH were enrolled in the study. Of these, 17 patients underwent treatment with NB-UVB therapy once or twice weekly and were eligible for analysis. The remaining 6 patients were lost to follow-up before completion of the treatment. Repigmentation was evaluated by two dermatologists using photographic documentation. RESULTS: In our trial, NB-UVB therapy was used successfully in 9 of 16 patients (56.2%), who showed more than 90% repigmentation. We found that 13 of 16 patients (81.3%) experienced at least 50% repigmentation. The repigmented sites showed an excellent color match. No signs of recurrence have been detected in 11 of these 16 patients (68.7%) up to the present time (13.2 ± 8.2 months of follow-up). LIMITATIONS: Our study includes a small number of subjects examined, and it was an uncontrolled and non-double-blind study. CONCLUSIONS: The findings of this study suggest that NB-UVB therapy is an effective and safe method for use in the treatment of PMH.

RESUMEN

BACKGROUND: In Korea, many patients diagnosed with basal cell carcinoma (BCC) have a history of laser ablations of undiagnosed lesions. OBJECTIVE: To evaluate the clinical/pathological and surgical features of BCC developing from undiagnosed lesions following laser ablations (not full-face cosmetic ablations) and to compare them with primary BCCs. METHODS: This study enrolled 359 patients with 373 biopsy-proven BCC lesions. All of the patients were treated by Mohs micrographic surgery (MMS) at the Department of Dermatology, Pusan National University Hospital from 1998 to 2008. BCC was classified by previous treatment history of lesion ablative laser: post-laser BCC vs primary BCC. We conducted a retrospective study through clinical photographs, pathology slides, and MMS sheets. RESULTS: Among 373 BCCs, 58 lesions (15.5%) were post-laser BCCs. The post-laser BCC group was younger (59.9 vs 65.4 years, P = .001), but had a longer disease interval until pathologic diagnosis (7.18 vs 3.33 years, P < .0001) than the primary BCC group. The post-laser BCC group had a greater frequency of the micronodular pattern (22.4% vs 10.8%, P = .01), required more stages of excision (2.69 ± 1.63 vs 2.15 ± 1.05, P < .001), and had fewer cases with one Mohs stage excision (10.3% vs 27%, P = .006) than the primary BCC group. LIMITATIONS: We could not identify the type of laser used in all 58 cases; instead, we supposed that most of the patients were likely treated with the carbon dioxide laser. CONCLUSIONS: The results demonstrated that the post-laser BCC group had a longer disease interval to diagnosis, a more aggressive histologic pattern, and required more stages of excision in MMS than the primary BCC group.

RESUMEN

Oral hairy leukoplakia (OHL) is caused by the reactivation of a previous Epstein-Barr virus (EBV) infection in the epithelium of the tongue. Most lesions are characterized by corrugated whitish patches on the lateral border of the tongue. It is frequently associated with AIDS, but cases in patients with other immunosuppressed states have also been reported. In leukemia patients, OHL is rarely encountered, and appears only after chemotherapy. We report a case of OHL which occurred as a presenting sign of acute myeloid leukemia (AML) in a previously healthy 15-year-old child. A 15-year-old boy presented with a whitish patch on the left lateral border of the tongue. The biopsy specimen revealed papillomatosis, hyperkeratosis, acanthosis and ballooning degeneration in the stratum spinosum. The patient was EBV seropositive, and PCR analysis of EBV DNA in the lesional tissue was positive. After the diagnosis of OHL in dermatologic department, the patient was referred to pediatrics due to the abnormal peripheral blood smear, and was diagnosed with AML.

RESUMEN

Pyodermatitis-pyostomatitis vegetans (PPV) is a rare chronic pustular and vegetating mucocutaneous dermatosis. The oral lesions present as multiple, friable and yellowish pustules, which form "snail tracts" and rupture easily. The cutaneous lesions begin as crusted erythematous papulopustules that coalesce to form large vegetating plaques, usually in the axillae, genital area and scalp. Cutaneous lesions usually develop at the same time as the oral lesions or thereafter. PPV is usually considered as a specific marker for inflammatory bowel disease since the concurrence of PPV and inflammatory bowel disease has been reported in approximately 70% of cases. We report two patients who showed typical clinical and histopathological features of PPV, but were not accompanied by inflammatory bowel disease.
