Validation of the diagnostic criteria for atopic dermatitis.

OBJECTIVE: To validate the accuracy of newly proposed diagnostic criteria for atopic dermatitis (AD). DESIGN: Double-blind, cross-sectional study comparing the achievement of new criteria with the diagnosis of a dermatologist. SETTING: A private, general dermatology, outpatient clinic. PATIENTS: A sample of 416 consecutive patients attending the clinic within 2 months (146 males and 270 females), consisting of 60 patients with AD and 356 control patients with other skin diseases. MAIN OUTCOME MEASURES: Sensitivity, specificity, and positive and negative predictive values of proposed criteria in the diagnosis of AD. RESULTS: Sensitivity, specificity, and positive and negative predictive values of proposed diagnostic criteria for AD were 10.0% (95% confidence interval [CI], 4.1%-21.2%), 98.3% (95% CI, 96.2%-99.3%), 50.0% (95% CI, 22.3%-77.7%), and 86.6% (95% CI, 82.8%-89.7%), respectively. CONCLUSIONS: These diagnostic criteria for AD are highly specific and are suitable for clinical trials. However, they may not achieve enough sensitivity to be useful for large, population-based epidemiological studies or for routine clinical practice, at least in Iran.     

Body Dysmorphic Disorder

Patients with body dysmorphic disorder (BDD) often present to dermatologists and cosmetic surgeons. BDD is a relatively common yet underrecognized disorder that consists of a distressing or impairing preoccupation with an imagined or slight defect in appearance. Although any body area can be the focus of concern, preoccupation with the appearance of the skin, hair, and nose are most common. Typical associated behaviors include skin picking, mirror checking, and camouflaging (e.g., with a hat or makeup). Reassurance seeking is another common behavior that may be enacted with surgeons and dermatologists. BDD is associated with marked impairment in functioning, notably poor quality of life, and a high suicide attempt rate. The disorder appears relatively common in dermatologic and cosmetic surgery settings; in fact, dermatologists may be the type of practitioner most often consulted by patients with BDD. Psychoeducation is an important element in the treatment of BDD. For patients who compulsively pick at their skin, it is generally ineffective to simply advise them to stop picking. Educating them that the picking is a symptom of BDD, and is treatable, can be helpful. For skin pickers, a combination of psychiatric and dermatologic treatment may be best. It is probably best to avoid cosmetic procedures. Although definitive data on the treatment outcome of surgery and dermatologic treatment for BDD are lacking, and although no one can predict how a given patient will respond to such treatment, available data suggest that these treatments are unlikely to be successful and may even make the patient’s condition worse. Rather than referring the patient to another dermatologist or cosmetic surgeon, we recommend attempting to refer the patient to a psychiatrist for cognitive-behavioral therapy or pharmacotherapy. Available data indicate that serotonin (5-hydroxytryptamine; 5-HT) reuptake inhibitors are often effective for BDD. In recent years, BDD has gone from being a neglected psychiatric disorder to one that is becoming better recognized and understood. Nonetheless, research on this disorder is still in its early stages, and much more investigation of BDD is needed, especially in surgical and dermatologic settings. Treatment recommendations will be modified in the future as more research is done. In the meantime, it is important that dermatologists and surgeons screen patients for BDD and accurately diagnose this condition, as available psychiatric treatments are very promising for patients with this distressing and sometimes disabling disorder.     

Five-year follow-up of a randomized, prospective trial of topical methyl aminolevulinate photodynamic therapy vs surgery for nodular basal cell carcinoma

OBJECTIVE: To compare 5-year lesion recurrence rates in primary nodular basal cell carcinoma treated with topical methyl aminolevulinate photodynamic therapy (PDT) or simple excision surgery. DESIGN: Prospective, randomized, multicenter study. SETTING: University hospital dermatology departments. PATIENTS: A total of 97 patients, 50 with 53 lesions treated with methyl aminolevulinate PDT and 47 with 52 lesions treated by excision surgery, were included in the per protocol analysis. Of the lesions treated with methyl aminolevulinate PDT and surgery, 49 and 52, respectively, showed complete clinical response at 3 months after treatment and were observed for long-term outcome evaluation. INTERVENTIONS: Topical methyl aminolevulinate cream, 160 mg/g, applied for 3 hours before illumination (75 J/cm(2) of red light at 570 to 670 nm) on 2 or 4 occasions (12 [23%] of 53 lesions); or excision surgery. MAIN OUTCOME MEASURES: Histologically confirmed lesion recurrence, sustained lesion complete response rate (time-to-event analysis), and investigator assessment of cosmetic outcome, 5 years after the last treatment. RESULTS: At 5 years, recurrence was documented in 7 (14%) of 49 lesions (95% confidence interval [CI], 6%-27%) treated with methyl aminolevulinate PDT vs 2 (4%) of 52 lesions (95% CI, 1%-13%) treated with excision surgery (P = .09). Estimated sustained lesion complete response rates were 76% (95% CI, 59%-87%) and 96% (95% CI, 84%-99%), respectively (P = .01). More patients treated with methyl aminolevulinate PDT than surgery had an excellent or good cosmetic outcome: 27 (87%) of 31 patients (95% CI, 70%-96%) vs 19 (54%) of 35 patients (95% CI, 37%-71%) (P = .007). CONCLUSIONS: Long-term follow-up indicates superior efficacy of surgery to methyl aminolevulinate PDT in nodular basal cell carcinoma. However, methyl aminolevulinate PDT is also an effective treatment for this indication and exhibits a more favorable cosmetic outcome.     

Oral corticosteroid use is effective for cutaneous hemangiomas: an evidence-based evaluation

OBJECTIVES: To determine the efficacy of systemic corticosteroid therapy in treating enlarging, problematic cutaneous hemangiomas and to assess the relationship of dose to response and adverse effects. DESIGN: A quantitative systematic literature review was performed and inclusion and exclusion criteria were applied. SETTING: Patients were treated in primary care, referral centers, and institutional practices. Most patients were ambulatory, although some required hospitalization. PATIENTS: Inclusion criteria were original case series with a minimum of 5 patients with enlarging, problematic cutaneous hemangiomas treated with systemic corticosteroids. Exclusion criteria were being older than 2 years, receiving simultaneous other treatments, being lost to follow-up, or having insufficient information. Twenty-four original case series met inclusion criteria; 10 case series remained (184 patients) after exclusion criteria were applied. INTERVENTION: Patients were given a mean prednisone equivalent daily dose of 2.9 mg/kg (95% confidence interval [CI], 2.7-3.1 mg/kg) for a mean of 1.8 months (95% CI, 1.5-2.2 months). MAIN OUTCOME MEASURES: Response and rebound rates and dose-response and adverse effects-response relationships in responders vs nonresponders. RESULTS: Response was 84% (95% CI, 78%-89%; range, 60%-100%) and rebound was 36% (95% CI, 29%-44%; range, 0%-65%). A significant difference was found between the mean dose administered to responders vs nonresponders (P<.001). No significant difference was observed as to the occurrence of adverse effects (P =.3). CONCLUSION: Systemic corticosteroid treatment seems to be effective for problematic cutaneous hemangiomas of infancy.     

Prevalence and predictors of skin disease in the Women's Interagency HIV Study (WIHS)

OBJECTIVE: We attempted to determine the prevalence and predictors of skin disease in a cohort of women with and at risk for HIV infection. METHODS: We analyzed baseline data from a multicenter longitudinal study of HIV infection in women. RESULTS: A total of 2018 HIV-infected women and 557 HIV-uninfected women were included in this analysis. Skin abnormalities were reported more frequently among HIV-infected than uninfected women (63% vs 44%, respectively; odds ratio [OR] 2.10; 95% confidence interval [95% CI], 1.74-2.54). Infected women were also more likely to have more than 2 skin diagnoses (OR, 3.27; 95% CI, 1.31-8.16). Folliculitis, seborrheic dermatitis, herpes zoster, and onychomycosis were more common among HIV-infected women (P < .05). Independent predictors of abnormal findings on skin examination in the infected women were African American race (OR, 1.38; 95% CI, 1.07-1.77), injection drug use (OR, 2.74; 95% CI, 2.11-3.57), CD4(+) count less than 50 (OR, 1.68; 95% CI, 1.17-2.42), and high viral loads (100,000-499,999 = OR, 1.77; 95% CI, 1.32-2.37; > 499,999 = OR, 2.15; 95% CI, 1.42-3.27). CONCLUSION: HIV infection was associated with a greater number of skin abnormalities and with specific dermatologic diagnoses. Skin abnormalities were also more common among women with CD4(+) cell depletion or higher viral load.     

Ultrasonography using simple diagnostic criteria vs palpation for the detection of regional lymph node metastases of melanoma

OBJECTIVES: Our aims were (1) to compare the respective ability of ultrasonography and palpation to detect nodal metastasis during initial staging and follow-up in patients having melanomas and (2) to assess, we believe for the first time, which ultrasound criteria should be used to define metastasis in cases of cutaneous or mucosal melanoma. DESIGN: Prospective single-center study. Nodal metastasis was confirmed by histopathologic evaluation. SETTING: Dermatology and radiology departments of a university hospital. PATIENTS: A total of 160 new consecutive patients with stage I to stage III melanoma. INTERVENTION: Experienced operators independently performed 391 paired palpation and ultrasonographic examinations. MAIN OUTCOME MEASURES: Firm enlarged nodes found on palpation were considered metastatic. On ultrasonographic examination, circular or oval hypoechoic lymph nodes lacking hyperechoic hila were considered metastatic (stringent criteria). Nodes with 2 or fewer of these patterns and other published signs of metastasis (ie, intranodal nodular hypoechoic focus and irregularity of the node margin) were considered suspicious. RESULTS: Over the 6-year study period 33 patients developed nodal metastasis. For palpation and ultrasonography using the stringent criteria, respectively, sensitivity was 41.5% (95% confidence interval [95% CI], 29.6-53.5) and 76.9% (95% CI, 66.7%-87.2%) (P<.001) and specificity was 95.7% (95% CI, 93.5%-97.9%) and 98.4% (95% CI, 97.1%-99.8%) (P<.05). Including ultrasonographically suspicious lymph nodes significantly lowered specificity (86.2% [95% CI, 82.5-89.9]) (P<.05) without improving sensitivity. Previous lymphadenectomy had little impact on ultrasonographic findings. CONCLUSION: Ultrasonography using stringent criteria of nodal metastasis, which are easy to identify and reliable, is superior to palpation for early detection of regional lymph node metastases of melanoma.     

High seroprevalence to Bartonella quintana in homeless patients with cutaneous parasitic infestations in downtown Paris

Bartonella quintana infections have recently been reported in homeless patients. We prospectively studied the prevalence of and the factors associated with a positive serology to B quintana in the homeless population of downtown Paris. The following data were recorded: ongoing cutaneous parasitic infestation, years of homelessness, living status, previous episodes of body pediculosis and scabies, alcoholism, intravenous drug use, known immunodepression (including undernutrition and known HIV infection), and contacts with animals. B quintana serology was performed in 57 patients and in 53 age- and sex-frequency-matched downtown Paris volunteer blood donors. Thirty-one patients (54%; 95% confidence interval [CI], 41%-68%) had a positive B quintana serology as compared with 2% in the control group (P <.0001); 8 of 57 patients (14%; 95% CI: 6%-26%) had a serologic profile of an evolving infection. Age and years of homelessness were independently associated with a positive B quintana serology with adjusted relative risks (RRs) of 2.9 (95% CI, 1.4-5.9) for age 40 years and older and 1.7 (95% CI, 1.1-2.7) for years of homelessness 3 or more. Our results suggest a high prevalence of past and recent infections with B quintana in the downtown Paris homeless population with cutaneous parasitic infestations.     

Influence of sexual activity on cytomegalovirus seroprevalence in the United States, 1988-1994

BACKGROUND: Sexual and nonsexual transmission of cytomegalovirus (CMV) occurs, but the frequency of sexual transmission in the general population of the United States is unknown. METHODS: Using data from 15- to 44-year-old (n = 7883) participants of the Third National Health and Nutrition Examination Survey (1988-1994), we examined the association between CMV seroprevalence and sexual activity markers. Using logistic regression, we calculated standardized prevalence differences (PDs)-the weighted average CMV prevalence among higher sexual risk groups minus CMV prevalence among the lowest sexual risk group-for each of several sexual activity markers (ever had sex, number of sex partners [lifetime and past year], age at first intercourse, potential years of sexual activity, ever use oral contraceptives, herpes simplex virus type 2 antibody, and a calculated composite marker). RESULTS: Even after controlling for covariates, we found associations between CMV seroprevalence and sexual activity among non-Hispanic black [all PDs for sexual activity markers were positive and composite PD = 8.5%, 95% confidence interval (CI) = 4.0%-13.1%] and non-Hispanic white women (15 of 18 PDs for sexual activity markers were positive and composite PD = 10.8%, 95% CI = 3.1%-18.5%). We found a borderline significant association among Mexican American women (13 of 18 PDs for sexual activity markers were positive and composite PD = 3.5%, 95% CI = -0.7% to 7.6%). We found little or no association within each racial/ethnic group of men. CONCLUSIONS: Sexual activity measurably influences CMV seroprevalence among women of childbearing age, indicating that congenital CMV prevention messages should include strategies to reduce sexual transmission of CMV among pregnant women.     

Prevalence of skin disease among nursing home patients in southern Taiwan

BACKGROUND: Continuing advances in medical care and nutrition have prolonged the lifespan and expanded the elderly demographic world-wide. Despite increasing elderly populations within Taiwanese nursing homes, there has been a lack of dermatologic surveys, and the prevalence of skin conditions within this group is unknown. METHODS: To establish the prevalence of skin disease within nursing homes in southern Taiwan, we undertook a dermatologic and epidemiologic investigation of 398 patients in Tainan City, southern Taiwan, between November 1999 and February 2000. RESULTS: This study revealed that more than half of all nursing home patients suffered from fungus (61.6%) and xerosis (58.3%), while other pruritic skin diseases, such as dermatitis and scabies, were less prevalent at 7.3% and 3.3%, respectively. Risk factors for fungal infection included bedridden status (risk ratio (RR), 1.2; 95% confidence interval (CI), 1.1-1.4) and male gender (RR, 1.2; 95% CI, 1.0-1.3). Xerosis was statistically correlated with an age range of 80-90 years (RR, 1.2; 95% CI, 1.0-1.4) when compared to other age ranges. Current scabies diagnosis was strongly associated with a previous history of scabies (RR, 8.9; 95% CI, 1.7-21.1). CONCLUSIONS: Our study provides clinically relevant data regarding the prevalence of skin diseases in institutionalized Taiwanese patients for the first time. The results suggest that scabies persists within some nursing homes despite treatment, and that some patients remain undiagnosed. The dermatologic needs of these Taiwanese patients are not currently being satisfied.     

Prevalence and incidence of hepatitis B virus infection in STD clinic attendees in Pune,India

OBJECTIVES: To estimate the prevalence and incidence of hepatitis B virus (HBV) infection among patients attending three STD clinics in Pune, India, and to identify associated risk factors. METHODS: Of the 2098 patients screened at STD clinics in Pune during 1996, 497, who returned for at least one follow up visit, were screened for various markers of HBV infection (HBsAg, anti-HBs, anti-HBc), HIV antibody, and VDRL. RESULTS: Of the 497 participants 3.6%, 26.5%, and 43.2% were positive for HBsAg, anti-HBs, and anti-HBc respectively. Tattooing (AOR 1.64, 95% CI 1.03 to 2.64) was found to be independently associated with presence of core antibody. Additionally, history of being in commercial sex work and history of a genital ulcer were independently associated with a positive anti-HBc antibody test (AOR 12.45, 95% CI 5.58 to 27.82 and AOR 1.70, 95% CI 1.09 to 2.66, respectively). 72 out of 497 (14.5%) participants were HIV positive at baseline. HIV-1 antibody positive patients were more likely to have a positive anti-HBc test (69.4% v 39.0%, p<0.001). 30 out of 282 participants, negative for anti-HBc antibody at enrolment, seroconverted subsequently, resulting in an incidence of 10.86 per 100 person years (95% CI 7.2%, 14.5%) (mean and accumulated follow up of 11.7 months and 276.17 person years, respectively). CONCLUSIONS: A high prevalence and incidence of HBV infection, seen in STD clinic attendees underscore the need to provide HBV vaccine to commercial sex workers and their clients in India.     

Barriers to reproductive tract infection (RTI) care among Vietnamese women: implications for RTI control programs

BACKGROUND: Vietnamese women may be especially vulnerable to reproductive tract infections (RTIs) and their biological and social sequelae. Few data are available on the prevalence of and health-seeking behavior for RTIs among women in Vietnam. GOAL: To assess prevalence of RTI symptoms, describe treatment-seeking behaviors, and identify barriers to care among Vietnamese women. STUDY DESIGN: A population-based survey was conducted among 1163 Vietnamese women aged 18 years to 49 years. RESULTS: Five hundred seven women (43.6%) reported RTI symptoms in the previous 6 months, including abnormal vaginal discharge (78.3%), lower abdominal pain (46.7%), and genital ulcers (3.6%). Sixty-four percent of these women sought care at some type of medical venue: health station (i.e., government clinic; 24.7%), hospital (15.8%), pharmacy (15.2%), or private doctor (8.1%). The remaining women ignored symptoms (24.8%) or were self-treated (11.4%). In multivariate analysis, stigma associated with sexually transmitted infections (odds ratio [OR] = 1.83; 95% confidence interval [CI] = 1.25-2.70); not seeking informal advice (OR = 2.90; 95% CI = 1.82-4.62); mildness of symptoms (OR = 3.01; 95% CI = 1.45-6.23); absence of perceived morbidity (OR = 3.56; 95% CI = 2.20-5.77); and short duration of symptoms (OR = 2.53; 95% CI = 1.04-6.16) were significantly associated with ignoring RTI symptoms. CONCLUSION: A substantial number of women in northern Vietnam who reported RTI symptoms did not seek care. Interventions to raise awareness about RTI symptoms and their consequences, dissipate negative stereotypes, and encourage open discussion about RTIs should facilitate appropriate care-seeking for RTIs.     

Characterization of dermatological diagnoses among hospitalized patients experiencing homelessness

While previous studies have characterized the types of dermatological disease among people experiencing homelessness (PEH) in the outpatient setting, dermatological disease among hospitalized PEH has never been evaluated. Therefore, we performed a cross-sectional analysis of hospitalized patients who received dermatology consultations at two San Francisco hospitals between March 2018 and March 2020 and compared the odds of diagnostic categories between PEH and patients with stable housing. In both unadjusted and adjusted analyses, PEH had significantly higher odds of bacterial skin infections [adjusted odds ratio (aOR) = 2.29, 95% CI 1.46–3.61], ectoparasitic disease (aOR = 9.43, 95% CI 3.79–23.47), psoriasis or seborrhoeic dermatitis (aOR = 2.50, 95% CI 1.43–4.36) and venous stasis or lymphoedema (aOR = 2.54, 95% CI 1.23–5.27) and significantly lower odds of drug reactions (aOR = 0.34, 95% CI 0.18–0.67). Overall, these findings highlight the unique dermatological challenges among hospitalized PEH and suggest potential strategies to facilitate equitable dermatology care delivery.     

Prediction of survival for patients with bullous pemphigoid: a prospective study

OBJECTIVE: To identify the prognostic factors of bullous pemphigoid (BP). DESIGN: Prospective study of patients with BP included in a randomized, controlled trial. SETTING: Twenty dermatology departments in France.Patients One hundred seventy patients with BP initially treated with a 40-g/d dosage of clobetasol propionate cream (testing sample) and 171 patients initially treated with oral corticosteroids at a dosage of 0.5 or of 1.0 mg/kg per day, depending on the extent of BP (validation samples). MAIN OUTCOME MEASURES: The end point was overall survival during the first year after BP diagnosis. From the testing sample, associations of clinical and biological variables with overall survival were assessed using univariate and multivariate analyses. Selected predictors were included in a prognostic model. To verify that these predictors were not dependent on the treatment used, the model was then validated independently on the 2 series of BP patients treated with oral corticosteroids. RESULTS: Median age of the BP patients included in the testing sample was 83 years. The 1-year Kaplan-Meier survival rate was 74%. From univariate analysis, the main deleterious predictors were demographic factors (ie, older age and female sex), associated medical conditions (ie, cardiac insufficiency, history of stroke, and dementia), and low Karnofsky score, which is a measure of the patient's general condition. No factors directly related to BP, in particular extent of cutaneous lesions, were shown to be related to the patients' prognosis. From multivariate analysis, only older age (P = .02) and low Karnofsky score (P<.001) appeared independently predictive of death. From the Cox model including these 2 predictors, the predicted 1-year survival rates were 90% (95% confidence interval [CI], 85%-96%) for patients 83 years or younger with Karnofsky score greater than 40, 79% (95% CI, 69%-90%) for patients older than 83 years with Karnofsky score greater than 40, 65% (95% CI, 50%-86%) for patients 83 years or younger with Karnofsky score of 40 or less, and 38% (95% CI, 26%-57%) for patients older than 83 years with Karnofsky score of 40 or less. Kaplan-Meier survival distributions of patients from the validation samples appeared clearly separated according to these 4 categories and were in close agreement with corresponding predicted 1-year survival rates obtained from the testing sample. CONCLUSIONS: The prognosis of patients with BP is influenced by age and Karnofsky score. These predictors are easy to use and should facilitate the management of BP.     

Health care access and follow-up of chlamydial and gonococcal infections identified in an emergency department

BACKGROUND: We examined 2 potentially important factors influencing successful treatment of Chlamydia trachomatis (Ct) and Neisseria gonorrhoeae (GC) infections identified in an emergency department (ED), health care coverage and reporting the ED as a primary source for health care. METHODS: Adult patients aged 18 to 35 years attending an urban ED were screened for Ct and GC. Patients testing positive were contacted by Disease Intervention Specialists and notified of their infection status. Analyses focus on infected patients for whom we have treatment and follow-up information. We used generalized linear models with log link and binomial error distribution to estimate risk ratios (RRs) and 95% confidence intervals (CI). RESULTS: Of 5537 patients screened in the ED, 348 (6.3%) tested positive for Ct, 143 (2.6%) tested positive for GC, and 43 (0.8%) tested positive for both. Overall, 20% of infected patients did not receive treatment. Among infected patients with no health care coverage 25% (n = 56) were untreated compared with 15% (n = 47) of patients reporting health care coverage (RR: 1.7, 95% CI: 1.2-2.3). Among patients reporting the ED as a primary source for health care 26% (n = 27) were untreated compared with the 18% (n = 77) reporting receiving health care from non-ED sources (RR: 1.4, 95% CI: 1.0-2.1). CONCLUSIONS: EDs often serve as primary care sites for difficult-to-reach populations. We were able to successfully locate and treat the greater part of ED-identified infections. However, one-fifth of infected patients did not receive treatment. ED-based screening programs can benefit from integration with local public health infrastructure to improve notification and treatment services.     

Enhanced survival in patients with multiple primary melanoma

OBJECTIVE: To calculate survival probabilities of patients with 3 or more multiple primary melanomas. DESIGN: Retrospective cohort study of patients with primary melanoma. SETTING: Patients treated at a tertiary center (Sydney Melanoma Unit, Sydney, Australia) for stage I or II melanoma between 1983 and 1999.Patients From 5250 patients with primary melanoma, 264 (5.0%) had double and 34 (0.6%) had 3 or more primary melanoma lesions. RESULTS: The estimated 10-year risk for developing a second primary melanoma in these patients was 12.7% (95% confidence interval [CI], 10.5%-14.9%). For those patients who had 2 primary melanomas, the estimated 10-year risk of developing a third lesion was 27.7% (95% CI, 14.7%-36.7%). When controlling for known prognostic factors in a proportional hazards regression model, the number of primary melanomas was a significant favorable survival predictor when the thickest or the first tumor was modeled. In patients with 3 or more primary melanomas, 31 survived when 25 (95% CI, 22-27) were expected to survive. Patients who survive longer may have the opportunity to develop multiple primary melanomas. Patients who encountered all their primary lesions within 2 years may not be subject to this bias. Within the 3 or more melanoma set, 11 patients had all primary melanomas within 2 years. All survived, whereas 9 (95% CI, 8-10) were expected to survive. CONCLUSIONS: Patients with 3 or more primary melanoma lesions survive longer than anticipated. Such enhanced survival in patients with 3 or more primary melanomas may be consistent with observations of an "immunization effect" in animals inoculated with multiple tumors.     

Prognostic value of blood eosinophilia in primary cutaneous T-cell lymphomas

OBJECTIVE: To investigate the prognostic value of initial characteristics including blood eosinophilia in patients with primary cutaneous T-cell lymphoma. DESIGN: A retrospective inception cohort, patients included from date of diagnosis (1982-1998). SETTING: Two dermatology departments of a university hospital.Patients A total of 104 patients with cutaneous T-cell lymphoma, including patients with mycosis fungoides (n = 69), Sézary syndrome (n = 13), and nonepidermotropic cutaneous lymphoma (n = 22). The following variables were recorded: age, sex, diagnosis according to the European Organization for Research and Treatment of Cancer (EORTC) classification, type of skin involvement at the time of diagnosis, initial eosinophil absolute count, lactate dehydrogenase value, date of disease progression, and cause and date of death or date of last contact. MAIN OUTCOME MEASURES: Time from diagnosis to disease progression and to disease-specific death. RESULTS: The median follow-up was 43 months (range, 7-197 months). Estimated rates of disease progression and disease-specific death for 3 years were 19.5% (95% confidence interval [CI],11.3%-27.6%) and 9.9% (95% CI, 2.8%-13.6%), respectively. Univariable analysis of initial variables possibly influencing disease progression revealed significant prognostic value for diagnosis according to EORTC classification (hazard ratio [HR], 2.77; 95% CI, 1.04-7.41; P =.04), type of skin involvement (HR, 2.70; 95% CI, 1.00-7.25; P =.04), raised blood eosinophil absolute count (HR, 7.33; 95% CI, 2.84-18.91; P<.001), and raised serum level of lactate dehydrogenase (HR, 3.72; 95% CI, 1.58-8.78; P =.001).Concerning disease-specific death, significant prognostic indicators were diagnosis according to the EORTC classification (HR, 6.62; 95% CI, 1.68-26.12; P =.007) and a raised blood eosinophil absolute count (HR, 10.57; 95% CI, 2.28-49.0; P<.001). In multivariable analysis, only blood eosinophilia was associated with disease progression and disease-specific death. CONCLUSION: These results strongly suggest that blood eosinophilia at baseline is a prognostic factor in patients with primary cutaneous T-cell lymphoma.     

The frequency of common skin conditions in preschool-aged children in Australia: seborrheic dermatitis and pityriasis capitis (cradle cap)

OBJECTIVE: To determine the prevalence and severity of seborrheic dermatitis and pityriasis capitis in Australian preschool-aged children. DESIGN: A stratified cross-sectional skin survey using cluster sampling of centers throughout Victoria, Australia. SETTING: The study population included children attending child care centers, preschools, and Maternal and Child Health Centers, with the reference population being Australian children 5 years and younger. PARTICIPANTS: Of the 1,634 children in the original sample, 1.116 children aged 11 days to 5 years 11 months were included in the study. INTERVENTION: Parents completed a questionnaire recording demographic information and personal and family history of skin problems and related diseases. A dermatologist performed a total skin examination, including the diaper area for children younger than 12 months. MAIN OUTCOME MEASURE: The age- and sex-specific prevalence rates and site and severity of seborrheic dermatitis and pityriasis capitis were measured. RESULTS: The overall age- and sex-adjusted prevalence of seborrheic dermatitis was 10.0% (95% confidence interval [CI], 8.2%-11.7%): 10.4% (95% CI, 7.8%-12.9%) in boys and 9.5% (95% CI, 7.0%-12.0%) in girls. This was highest in the first 3 months of life, decreasing rapidly by the age of 1 year, after which it slowly decreased over the next 4 years. Most (71.9%) had disease classified as minimal to mild. Pityriasis capitis occurred in 41.7% (95% CI, 38.8%-44.6%) of the 1,116 children examined, with 85.8% categorized as minimal to mild only. CONCLUSIONS: Seborrheic dermatitis and pityriasis capitis are common in early childhood. Most children have minimal to mild disease that would require little if any treatment. Education programs directed at those caring for preschool-aged children are needed to provide information on simple preventative measures and treatment, if necessary, that could easily reduce the morbidity associated with these very common conditions.     

Chlamydia trachomatis among young Norwegian men: sexual behavior and genitourinary symptoms

OBJECTIVE: The study objective was to assess Chlamydia trachomatis (CT) prevalence, risk factors, and genitourinary symptoms among young men. METHODS: Sexually active men 18 to 30 years old were recruited during April through October 2005 at the student health services and through field work at university campuses in 2 Norwegian cities. A total of 1,032 participants completed a questionnaire on sexual behavior and provided first-void urine for CT testing. RESULTS: The overall CT prevalence was 7.8% (81 of 1,032). In multivariable analysis, >or=5 lifetime sexual partners (adjusted odds ratio [aOR]: 2.7, 95% confidence interval [CI]: 1.4-5.2), a burning sensation on urination (aOR: 5.7, 95% CI: 3.1-10.5), and penile discharge (aOR: 2.6, 95% CI: 1.1-6.3) were significant risk factors for a positive CT test, whereas condom use (last intercourse) was preventive (aOR: 0.4, 95% CI: 0.2-0.8). CONCLUSIONS: A CT prevalence of 7.8% was found among male students. Promotion of increased testing among men is important to prevent CT transmission.
