Childhood lichen sclerosus (LS) is a rare and often misdiagnosed inflammatory dermatitis with an unpredictable course. The complications of LS are architectural changes of the vulva; malignant transformation is possible. The objective of our study was to define the background and the long‐term course of childhood LS. A registery study identified 44 children with LS treated at Tampere University Hospital, Tampere, Finland, from 1982 to 2010. A questionnaire was sent to the identified patients and 15 responded. The clinical depiction of LS varied significantly. LS was diagnosed in only 16% of the patients at the referring unit. Autoimmune disorders were observed in 6 of the 44 patients. High prevalences of Turner's syndrome (2/44) and kidney disease (2/44) were noted. The majority of the patients were treated with topical corticosteroids. Eight developed architectural changes of the vulva. The questionnaire revealed that three of six patients who were asymptomatic at the end of the registery study follow‐up experienced a recurrence of symptoms. None of them were undergoing follow‐up. Nine of the 15 patients reported reduced quality of life. Childhood LS is a heterogeneous disease with a remarkable effect on quality of life. The misdiagnosis of childhood LS is common. The association between LS and autoimmune diseases should be noted. The high prevalence of Turner's syndrome raises questions regarding the influence of low estrogen levels on the development of LS. The prognosis cannot be predicted, so long‐term follow‐up is recommended. New tools for diagnosis and surveillance are needed. 相似文献

Epidemiologic studies suggest that exposure to sunlight is the primary etiologic agent for basal cell carcinoma. Formation of UV-induced DNA damage is believed to be a crucial event in the process leading to skin cancer. In this study, repair of photoproducts in DNA was followed in the skin of patients with basal cell carcinoma and control subjects. The subjects were exposed to 800 J/m(2) Commission Internationale de 1'Eclairag of solar-simulating radiation on buttock skin. Biopsies were taken at 0 hour, 24 hours, and 3 weeks after the exposure. Two cyclobutane pyrimidine dimers, TT=C and TT=T, were measured using a sensitive (32)P-postlabeling assay. Initial levels of both TT=C and TT=T differed between individuals in both groups. The levels of TT=T in patients with basal cell carcinoma and controls were similar (9.9 +/- 4.0 and 9.2 +/- 2.9 products per 10(6) normal nucleotides), whereas the level of TT=C was significantly lower in controls than in patients with basal cell carcinoma (6.2 +/- 3.1 versus 10.9 +/- 4.5 products per 10(6) normal nucleotides). The fractions of TT=T remaining after 24 hours and 3 weeks were significantly higher in patients with basal cell carcinoma (72% and 11%) compared with controls (48% and 5%). A slower removal in patients with basal cell carcinoma than in controls was indicated also for TT=C (52% versus 42% remaining at 24 hours); however, the difference between groups was not significant. When including data from our previously reported small-scale study, the fraction of dimers remaining at 24 hours was significantly higher in patients with basal cell carcinoma for both TT=C and TT=T. The data suggest that patients with basal cell carcinoma have a reduced capacity to repair UV-induced DNA lesions. 相似文献

The relationship between pediatrics and child psychiatry has been discussed at length. Opportunities seem to exist for cooperation between the two specialties, and yet difficulties exist. This study compared attitudes toward childhood held by pediatricians and child psychiatrists, as well as by residents at the beginning and end of training in pediatrics, psychiatry, and child psychiatry. The attitudinal assessment tool was a 30-item questionnaire consisting of literary quotations with which respondents were asked to agree or disagree. The results suggest that pediatricians view childhood more positively than do child psychiatrists. These attitudinal differences exist at the beginning of residency training. Recommendations are made regarding how to facilitate better collaboration between pediatricians and child psychiatrists. 相似文献

BACKGROUND: Ultraviolet (UV) irradiation has a broad spectrum of biological effects and a capacity to initiate skin carcinogenesis through DNA damage. The effect of different wave bands of UV light on the production of DNA damage in human skin in situ was studied with a broadband UV-B lamp TL-12 and a narrowband UV-B lamp TL-01. METHODS: Eight psoriasis patients participated in the study. Their minimal erythema dose was assessed separately for the two UV-B wave band ranges. Test areas of buttock skin were irradiated with the two spectrally differing lamps using erythemally equivalent UV doses of 40 and 80 mJ/cm2 CIE (Commission International de I'Eclairage). Punch biopsies were taken from the irradiated areas, and UV-induced DNA lesions (cyclobutane pyrimidine dimers, CPDs) in the skin were analyzed with a 32P high-performance liquid chromatography postlabelling method. RESULTS: No UV source-dependent differences in the induced levels of CPDs were detected in this study. CONCLUSION: CPD production with broadband TL-12 and narrowband TL-01 UV-B lamps in situ did not differ when erythemally equivalent UV doses were used. The preliminary result needs to be confirmed in a larger study. 相似文献

Local anesthesia for neonatal circumcision. Effects on distress and cortisol response 总被引:1,自引:0,他引:1
A controlled, double-blind investigation was conducted to determine whether the dorsal penile nerve block using lidocaine hydrochloride without epinephrine would effectively reduce behavioral distress and adrenocortical responses to routine neonatal circumcision. The subjects were healthy male newborns whose parents had requested circumcision. Equal numbers (n = 20) were randomly assigned to circumcision with lidocaine, saline, or no injection. Dorsal penile nerve block was found to be a safe and easy technique that was effective in reducing behavioral distress and modifying the adrenocortical stress response. The injection itself did not increase stress reactions and did not offset the beneficial effects of anesthesia. If circumcisions are to be performed, they should be done as humanely as possible. 相似文献

AIM: To study the incidence, prevalence and clinical characteristics of childhood thyrotoxicosis in a population-based area comprising five counties in central Sweden. METHODS: Retrospective analysis of the medical records of all children below 16 y of age with thyrotoxicosis during a 10-y study period. RESULTS: Forty-six children were identified with thyrotoxicosis. The median age at onset was 11.7 y and 85% were females. At the end of the study period on 31 December 1999, the prevalence was 0.08 per 1000. The mean annual incidence was four times higher in the second 5-y period than in the first (2.7 and 0.7 per 100000, respectively; p < 0.001). A first-degree relative with thyrotoxicosis was found in 21% of the children and 11/46 children (24%) showed autoimmune-related co-morbidity. Increased heart rate was observed in 95%, goitre in 67% and exophthalmos in 33% of the children. TSH was completely suppressed and free T4 was clearly above the upper reference limit in all children. TSH receptor-stimulating antibodies and peroxidase antibodies were observed in 80% and 71% of the children, respectively. CONCLUSION: This study indicates an increase in the incidence of childhood thyrotoxicosis in a population-based area of central Sweden. A prospective study aimed at identifying specific aetiological risk factors for development of thyrotoxicosis has been initiated. 相似文献

Two hundred and ninety-five licensed floorball players from Finnish premier to fifth division were observed prospectively for one season to study the incidence, nature, causes and severity of floorball injuries. During the study period, 100 out of the 295 (34 %) players sustained 120 injuries. Thirty-seven percent (73/199) of the male players and 28 % (27/96) of the females suffered from an injury. The injury rate was 1.0 per 1000 practice hours for both sexes. The injury rates per 1000 game hours were 23.7 for men and 15.9 for women. One hundred injuries (83 %) were acute and the remaining 20 (17 %) were overuse injuries. Sprain was the most common type of injury in men while overuse injuries were the most frequent injury type in women. The lower extremity was involved in 62 %, spine or trunk in 19 % and upper extremity in 10 % of the injuries. The most commonly injured sites were the knee and ankle (22 % and 20 % of all injuries), followed by head and neck (8 %). In both sexes the majority of injuries were minor, level II, injuries. Ten of the knee injuries (38 %) were serious, level IV injuries, of which seven were ACL ruptures. In conclusion, the individual risk of injury in floorball is relatively low in game practice while rather high during the game itself. Before initiation of clinical trials on prevention of floorball injuries, an exact knowledge of the risk factors and mechanisms of floorball injuries are needed. 相似文献
