Mohs micrographic surgery for basal cell carcinomas: appropriateness of ‘Rotterdam’ criteria and predictive factors for three or more stages

Background In the Netherlands basal cell carcinomas (BCC) are eligible for Mohs microscopic surgery (MMS) if certain criteria are fulfilled. Objective To study the MMS indication criteria practised at the department of dermatology of the Erasmus University Medical Center, Rotterdam and to identify predictive factors for extensive subclinical tumour spread among BCCs eligible for MMS. Methods Pre‐operative patient and tumour characteristics were derived retrospectively between January 2nd 2006 and December 28th 2009 from 1174 patient records, accounting for 1464 BCCs. Multivariate logistic regression models were used to calculate crude and adjusted odds ratios (OR) with 95% confidence intervals (CI) for one vs. two or more stages and for narrow (≤2 stages) vs. extensive subclinical spread (≥3 stages). Results H‐zone location [adjusted OR 1.51 (95% CI 1.16–1.96)], recurrent tumour [adjusted OR 1.50 (95% CI 1.11–2.02)], aggressive subtype [adjusted OR 1.25 (95% CI 1.01–1.56)] and tumour size ≥11 mm [adjusted OR 1.53 (95% CI 1.20–1.96)] were significantly associated with two or more stages. Predictive factors for extensive subclinical spread were recurrent tumour [adjusted OR 2.26 (95% CI 1.61–3.17)], tumour size ≥21 mm [adjusted OR 1.69 (95% CI 1.13–2.51)] and location in the H‐zone [adjusted OR 1.68 (95% CI 1.15–2.46)]. Conclusion ‘Rotterdam’ indication criteria used for MMS are appropriate. Predictors for extensive subclinical spread are important for patients’ and surgeons’ expectations prior to the operation about time span, defect size, reconstruction and possible associated morbidity.     

Occupational nonsolar risk factors of squamous cell carcinoma of the skin: a population-based case-controlled study

The purpose of this study was to investigate associations between occupation, nonsolar environmental exposures, and risk of squamous cell carcinoma (SCC) of the skin. Data from the Southeastern Arizona Health Study-2 were used. This was a population-based case-controlled study [n = 795) conducted during 1992-1996 in southeastern Arizona to primarily assess the risk of skin SCC in relation to sun exposure. Multivariate logistic regression was used to calculate odd ratios as the estimate of effect. High-risk occupations were identified through literature review. There was evidence of a slightly elevated risk of skin SCC for subjects reporting a history of construction work (OR = 1.38, 95 % CI = 0.61-3.14), and automobile and machine work (OR = 1.21, 95 % CI = 0.48-3.06) Furthermore, there were no statistically significant associations between risk of skin SCC and history of exposure to specific chemical and other nonsolar environmental agents. A slight indication of increased risk for skin SCC was noted for exposure to nonsolar light (OR = 1.33, 95 % CI = 0.92-2.26), construction/machinery materials (OR = 1.12, 95 % CI = 0.76-1.84), fluorescent light (OR = 1.56, 95 % CI = 0.92-2.61), gypsum (OR = 1.84, 95 % CI = 0.68-5.0), coal tar and dandruff shampoos (OR = 1.28, 95 % CI = 0.85-1.9), and cement dust (OR = 1.81, 95 % CI = 0.90-3.62). A large although statistically insignificant risk was seen for exposure to arsenic (OR = 4.21, 95 % CI = 0.40-43.9) and ethylene glycol (OR = 8.46, 95 % CI = 0.77-92.9). Several of the results of this analysis are consistent with literature and conclusions from previous epidemiological studies. However, lack of power and small sample size deem these results as inconclusive until more research and larger studies are conducted.     

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.     

Dermatologist detection and skin self-examination are associated with thinner melanomas: results from a survey of the Italian Multidisciplinary Group on Melanoma

OBJECTIVE: To investigate patterns of detection and variables associated with early diagnosis of melanoma in a population at intermediate melanoma risk. DESIGN: Survey. SETTING: Hospital and university centers belonging to the Italian Multidisciplinary Group on Melanoma. PATIENTS: Eight hundred sixteen patients who were consecutively diagnosed as having melanoma and treated at 11 participating centers. MAIN OUTCOME MEASURE: Relationship between patterns of detection and patient's and physician's delay with melanoma thickness, assessed by multivariate analysis. RESULTS: A statistically significant association with early diagnosis was found for female sex (odds ratio [OR] for a lesion >1 mm in thickness, 0.70; 95% confidence interval [CI], 0.50-0.97), higher educational level (OR, 0.44; 95% CI, 0.24-0.79), residence in northern and central Italy (compared with southern Italy) (OR, 0.44; 95% CI, 0.30-0.65 and OR, 0.24; 95% CI, 0.15-0.37, respectively), and the habit of performing a skin self-examination (OR, 0.65; 95% CI, 0.45-0.93). When adjusted for all the previously mentioned variables, only melanoma detection made by a dermatologist, maybe incidentally, was associated with a statistically significant additional effect on early diagnosis (OR, 0.45; 95% CI, 0.28-0.73). No significant effect of anatomical site (trunk compared with other sites: OR, 0.83; 95% CI, 0.59-1.17), presence of atypical nevi (OR, 0.78; 95% CI, 0.52-1.17), and patient's delay (>3 months compared with < or =3 months: OR, 1.12; 95% CI, 0.78-1.60) was found. CONCLUSION: Future melanoma early diagnosis strategies should adequately stress the role of skin self-examination among the adult population, and should recommend that dermatologists perform a total skin examination to identify suspect lesions (such an examination should also be performed during consultations for other reasons).     

Factors affecting the recurrence rate of basal cell carcinoma

The aim of this retrospective survey was to determine recurrence rates after treatment of basal cell carcinomas in a single academic dermatology department. A total of 1016 patients with 1593 histologically verified basal cell carcinomas (n=1212 primary and n=381 relapsing) were included. Tumour localization, T-stage and the method of treatment were significant predictors of the risk of recurrence (forward Cox regression, p <0.001). The relapse rate for primary basal cell carcinomas on the scalp was highest (odds ratio (OR)=2.8, 95% confidence interval (CI) 1.5-5.3). T2 and T3 tumours showed a 2- and 3-fold increased relapse rate, respectively, compared with T1 basal cell carcinomas. Radiotherapy and surgical excision had the lowest relapse rates, whereas curettage and photodynamic therapy resulted in 5-year relapse rates of up to 70%. Patients with chronic skin diseases had a 50% lower risk of relapse than healthy patients (OR=0.5, CI=0.3-0.8). Recurrent basal cell carcinomas had a higher relapse rate than primary lesions (OR=1.8, CI=1.4-2.2). Patients treated in a specialized skin cancer unit had a 6.4-fold (CI=2.4-17.4) higher cure rate compared with those treated by less experienced physicians. Thus, in an uncontrolled, real-life situation curettage or photodynamic therapy are associated with significantly higher relapse risk than excision and radiotherapy and therefore should not be used for high risk primary tumours or recurrent tumours. Treatment in the setting of a specialized skin cancer unit yields a much lower relapse rate.     

Risk factors for incomplete excision of basal cell carcinomas

Incomplete excision of basal cell carcinomas (BCCs) may be followed by recurrence of the tumor. In order to detect risk factors for incomplete excision of BCCs we performed a cross-sectional study of 1278 patients who underwent a primary excision of BCCs, during a four-year period, within an ambulatory and hospital plastic surgery department setting. Incomplete excision occurred in 159 of 1478 primary excisions of BCCs (10.8%) and was significantly associated with location of the tumors in the eyelids (OR 3.64, 95% CI 1.96-6.71), ears (OR 2.51, 95% CI 1.25-4.94), naso-labial folds (OR 2.26, 95% CI 0.99-5.04) and nose (OR 1.88, 95% CI 1.30-2.71). There was an inverse association with location of the tumors in the upper limbs (OR 0.44, 95% CI 0.21-0.90), back (OR 0.12, 95% CI 0.02-0.48) or chest (OR 0.09, 95% CI 0.00-0.57). Baso-squamous differentiation was associated with incomplete excision of BCCs (p = 0.03). No association was observed between incomplete excision of BCCs and gender, age, setting of the operation (ambulatory vs. hospital), clinical appearance of the lesion (suspected BCCs vs. other diagnoses) or diameter of the lesions. In conclusion, incomplete excision of BCCs was associated with location of the tumors in the eyelids, ears, naso-labial folds and nose. We recommend that in patients with BCCs located in these sites, surgeons should commence particular surgical measures to avoid inadequate excisions of the tumors.     

Psoriasis is independently associated with psychiatric morbidity and adverse cardiovascular risk factors,but not with cardiovascular events in a population‐based sample

Background Psoriasis may significantly reduce quality of life. Previous studies reported an association of psoriasis and cardiovascular risk factors and cardiovascular events. The extent to which psoriasis is associated with psychiatric morbidity and the role of psychiatric comorbidity as a potential confounder of the association between psoriasis and cardiovascular morbidity require further investigation. Objectives To study the association between psoriasis, psychiatric morbidity and cardiovascular morbidity. Methods Case–control study utilizing an interdisciplinary administrative outpatient database from Germany. Patients with confirmed diagnosis of prevalent psoriasis within the study period (2003–2004) (n = 3147, mean age 57 years) were individually matched for age and gender with 3147 controls without psoriasis. The relationship of psoriasis with psychiatric morbidities (depression, stress‐related disorders, behaviour disorders and schizophrenic disorders), cardiovascular risk factors (diabetes, hypertension, obesity and dyslipidaemia) and cardiovascular events [myocardial infarction (MI), stroke] was investigated using logistic and linear regression models. Results Crude analyses suggested an association of psoriasis with depression, stress‐related disorders, behaviour disorders and cardiovascular risk factors, but not with MI [odds ratio (OR) 1.14; 95% confidence interval (95% CI) 0.81–1.62] or stroke (OR 0.97; 95% CI 0.61–1.54). Multivariate models controlling for age, gender and consulting behaviour indicated that psoriasis is independently associated with depression (OR 1.49; 95% CI 1.20–1.86), stress‐related disorders (OR 1.41; 95% CI 1.22–1.62), behaviour disorders (OR 1.58; 95% CI 1.05–2.39), diabetes (OR 1.21 95% CI 1.04–1.40), hypertension (OR 1.34; 95% CI 1.18–1.51), dyslipidaemia (OR 1.29; 95% CI 1.07–1.55), and obesity (OR 1.63; 95% CI 1.39–1.90). For each psychiatric condition, the likelihood of being affected significantly increased with each physician visit due to psoriasis, suggesting that the risk of psychiatric comorbidity increases with the severity of psoriasis. Conclusion Psoriasis appears to be independently associated with major psychiatric disorders and with cardiovascular risk factors, but not with cardiovascular events.     

Resource utilization and quality of life associated with congenital ichthyoses

We explored resource utilization (ResUtil) and quality of life (QOL) associated with congenital ichthyoses (CI). Subjects completed an online survey related to clinical severity, demographics, ResUtil, and QOL as measured according to the Dermatology Life Quality Index (DLQI). Validated Likert scales were used to evaluate severity of hyperkeratosis, erythema, and alopecia. ResUtil was determined according to time spent daily treating CI symptoms (TimeTx) and number of ichthyosis-related dermatology visits (DermVisits) per year. We used linear regression to investigate predictors of a transformed DLQI (sqrtDLQI) and logistic regression for ResUtil. Of 235 subjects, 60.2% were female, 83.8% were Caucasian, 42.3% had a family history (FamHx) of CI, and the mean age was 28.7 years (SD 20.3). Predictors for worse QOL were hyperkeratosis severity (β = 0.27, p < 0.01), erythema (β = 0.27, p < 0.01), TimeTx (β = 0.21, p < 0.01), ichthyosis type (β = 0.09, p < 0.01), and age (β = 0.01, p = 0.02). Predictors for DermVisits were hyperkeratosis severity (odds ratio [OR] = 1.38, 95% confidence limit [CL] = 1.01, 1.87), FamHx (OR = 0.28, 95% CL = 0.09, 0.85), age (OR = 0.97, 95% CI = 0.96, 0.99), and alopecia severity (OR = 1.43, 95% CL = 1.12, 1.82). Predictors for treatment duration were erythema (OR = 1.35, 95% CL = 1.02, 1.78), age (OR = 0.98, 95% CL = 0.96, 0.99), and DLQI (OR = 1.09, 95% CL = 1.03, 1.15). Increased hyperkeratosis severity and erythema negatively impact QOL in the CI. Furthermore, increased disease severity predicted greater ResUtil, whereas increased age and FamHx predicted less ResUtil. Our findings suggest that better therapies and increased patient education may improve QOL and decrease ResUtil.     

Riesgo de aparición de segundas neoplasias cutáneas en una cohorte de pacientes diagnosticados de carcinoma queratinocítico (carcinoma basocelular y carcinoma epidermoide) tratados con cirugía de Mohs. Estudio de cohortes prospectivo nacional

ObjectivePatients with nonmelanoma skin cancer (NMSC)—ie, basal cell carcinoma (BCC) or squamous cell carcinoma (SCC)—have an increased risk of developing a second skin cancer. The aim of this study was to describe the frequency, incidence per 1000 person-years, and predictors of a second skin cancer in a cohort of patients with NMSC treated with Mohs micrographic surgery (MMS).Material and methodsProspective study of a national cohort of patients with NMSC who underwent MMS at 22 Spanish hospitals between July 2013 and February 2020; case data were recorded in the REGESMOHS registry. The study variables included demographic characteristics, frequency and incidence per 1000 person-years of second skin cancers diagnosed during the study period, and risk factors identified using mixed-effects logistic regression.ResultsWe analyzed data for 4768 patients who underwent MMS; 4397 (92%) had BCC and 371 (8%) had SCC. Mean follow-up was 2.4 years. Overall, 1201 patients (25%) developed a second skin cancer during follow-up; 1013 of the tumors were BCCs (21%), 154 were SCCs (3%), and 20 were melanomas (0.4%). The incidence was 107 per 1000 person-years (95% CI, 101-113) for any cancer, 90 per 1000 person-years (95% CI, 85-96) for BCC, 14 (95% CI, 12-16) per 1000 person-years for SCC, and 2 (95% CI, 1-3) per 1000 person-years for melanoma. More men than women developed a subsequent skin cancer (738 [61%] vs 463 [39%]). The main risk factors were a history of multiple tumors before diagnosis (relative risk [RR], 4.6; 95% CI, 2.9-7.1), immunosuppression (RR, 2.1; 95% CI, 1.4-3.1), and male sex (RR, 1.6; 95% CI, 1.4-1.9).ConclusionPatients have an increased risk of developing a second tumor after MMS treatment of NMSC. Risk factors are a history of multiple tumors at diagnosis, immunosuppression, and male sex.     

Epidemiologic risk factors of basal cell carcinoma development and age at onset in a Southern European population from Greece

Background: Basal cell carcinoma (BCC) is the most common form of skin cancer with increasing incidence rates worldwide. Methods: To assess the association of BCC with epidemiologic risk factors in a Southern European population from Greece, we conducted a hospital‐based case–control study of 199 patients with BCC and 200 controls. Results: In the multivariate analysis, fair skin colour was associated with increased risk of BCC (OR: 4.9, 95% CI: 2.4–10.0). However, darker skin phototypes III/IV (patient’s reported sun sensitivity/tanning ability) showed a higher BCC risk (OR: 3.9, 95% CI: 1.8–8.5). Persons with occupational UV exposure of 5 years or more had a 2.7‐fold increased risk (95% CI:1.4–5.3). There was an increased risk of BCC related to the number of sunburns after the age of 20 years (OR: 3.2, 95% CI: 1.4–7.3) and solar lentigines (OR: 6.8, 95% CI: 3.6–12.8). Subgroup analysis showed that different risk factors are associated with early onset BCC including the presence of dysplastic nevi (OR: 6.4, 95% CI: 1.5–27.2), the number of weeks per year spent at the beach during childhood (OR: 8.9, 95% CI: 3.3–24.1) and the history of sunburns during childhood (OR:5.0, 95% CI: 1.3–19.1). Conclusions: Fair skin colour was significantly associated with BCC risk. The relation of sunburns during adulthood with BCC underlies the importance of sunburn prevention throughout life time. Early onset BCCs seem to have a different pathogenetic background and were associated with dysplastic nevi as well as intermittent sun exposure and sunburns during the early years of life.     

Type-specific seroprevalence of herpes simplex virus type 2 and associated risk factors in middle-aged women from 6 countries: the IARC multicentric study

GOAL: To determine type-specific seroprevalence of herpes simplex viruses (HSV-1 and HSV-2) and HSV-2 risk factors. STUDY DESIGN: Six-hundred fifty eight middle-aged control women (hospital-based in 4 of 6 countries) from a multicenter cervical cancer case-control study participated from 1985 to 1997. Type-specific serum IgG antibodies against HSV-1 and HSV-2 were detected with Western Blot. RESULTS: HSV-1 seroprevalence was 89% to 100% everywhere except Thailand (51%). HSV-2 seroprevalence ranged from 9% (Spain) to 57% (Colombia), and was independently associated with having >or=2 lifetime sexual partners overall [Odds ratio (OR), 2.1; 95% confidence interval (CI) 2.5-3.1], and in Morocco (OR, 2.7; 95% CI, 1.2-6.1) and Thailand (OR, 4.4; 95% CI, 1.3-15.4), and with being unmarried in Colombia, Peru, Spain, but not significantly in Mali.

Type 1 cytokine response and treatment outcome of genital HPV lesions.

OBJECTIVES: To determine the role of type 1 cytokines as predictors of response to treatment of genital HPV lesions with laser ablation with or without adjuvant systemic interferon alpha 2b (IFN-alpha). METHODS: Measurement of serum interleukin 2 (IL-2), IL-2 soluble receptor alpha (sIL-2 alpha), interferon gamma, and human papilloma virus (HPV) DNA in patients undergoing treatment of genital HPV lesions with carbon dioxide laser and systemic IFN-alpha. A randomised, placebo controlled study of 92 cases with 6 months of follow up. RESULTS: High IL-2/sIL-2 alpha was associated with 60% to 70% protection against recurrences both in the IFN-alpha and placebo groups (OR = 0.4, 90%, CI 0.1-2.5; OR = 0.3, 90% CI 0.0-1.8, respectively). Diagnostic phase serum IL-2 predicted favourable outcome (OR = 0.2, 90% CI 0.0-1.0) in women with high load of HPV DNA or HPV 16/18 DNA regardless of the adjuvant therapy. CONCLUSIONS: Serum IL-2 determinations may identify women with good prognosis following laser ablation of genital HPV lesions.     

Sex partner concurrency: measurement, prevalence, and correlates among urban 18-39-year-olds

BACKGROUND: Sex partner concurrency probably accelerates the spread of sexually transmitted disease (STD) and HIV, yet few data exist on population prevalence or correlates. GOAL: The goal of the study was to compare definitions and estimate the frequency of concurrent partnerships and to identify individual and partnership correlates of con-currency. STUDY DESIGN: A random-digit-dialing survey (n = 637) was performed to collect demographic information, sexual history and history of STD, and partnership characteristics. RESULTS: Men reported concurrency more frequently than women. For men, lifetime partners (odds ratio [OR], 1.15 per partner; 95% CI, 1.07-1.23), a night in jail (OR, 1.99; 95% CI, 1.03-3.82), and same sex partners (OR, 1.88; 95% CI, 0.92-3.84) were associated with concurrency. Important factors for women were first coitus before age 16 (OR, 2.90; 95% CI, 1.38-6.10), lifetime partners (OR, 1.09 per partner; 95% CI, 1.01-1.16), and STD diagnoses during relationship (OR, 3.53; 95% CI, 1.55-8.05). Partnership characteristics associated with concurrency included lifetime partners (OR, 1.09; 95% CI, 1.05-1.14), race discordance (OR, 1.72; 95% CI, 1.14-2.59), married/living together (OR, 0.60; 95% CI, 0.36-0.98), night in jail (OR, 2.04; 95% CI, 1.32-3.17), partnership duration of >6 months (OR, 2.43; 95% CI, 1.41-4.19), and STD diagnoses during relationship (OR, 2.68; 95% CI, 1.42-5.07). CONCLUSIONS: Concurrency was independently associated with individual STD risk. Sex differences may reflect true behavioral differences or differential reporting.     

Predictors of chronic pelvic pain in an urban population of women with symptoms and signs of pelvic inflammatory disease

OBJECTIVE: The objective of this study was to assess the risk profile for chronic pelvic pain (CPP) after pelvic inflammatory disease (PID). STUDY: Multivariate logistic regression was used to assess risk factors for CPP in a longitudinal study of 780 predominately black, urban women with clinically suspected PID: complaints of acute pain (<30 days); a clinical finding of pelvic tenderness; and leukorrhea, mucopurulent cervicitis, or untreated gonococcal or chlamydial cervicitis. CPP was defined as pain reported at >or=2 consecutive interviews conducted every 3 to 4 months for 2 to 5 years. RESULTS: Nonblack race (odds ratio [OR], 2.17; 95% confidence interval [CI], 1.31-3.58), being married (OR, 2.06; 95% CI, 1.02-4.18), a low SF-36 mental health composite score (OR, 2.71; 95% CI, 1.69-4.34), >or=2 prior PID episodes (OR, 2.84; 95% CI, 1.07-7.54), and smoking (OR, 1.65; 95% CI, 1.01-2.71) independently predicted CPP. Histologic endometritis or evidence of endometrial Neisseria gonorrhoeae or Chlamydia trachomatis infection was negatively associated with CPP (OR, 0.69; 95% CI, 0.44-1.10). CONCLUSIONS: A range of demographic, clinical, historical, and behavioral factors predict CPP after PID.     

Risk factors associated with onychomycosis

OBJECTIVE: To examine possible risk factors related to onychomycosis. BACKGROUND: Onychomycosis is a common disease with multifactorial aetiology, but little is known about the risk factors for this disease. PATIENTS AND METHODS: Questions related to signs, symptoms and possible risk factors associated with onychomycosis were sent to 3992 persons aged 16 years and older selected randomly from the Icelandic National Registry. Patients with suspected onychomycosis, based on photographs, were offered mycological examination. Data from the questionnaire and the results of mycological examination were used to calculate the odds ratio (OR) for several factors that might be associated with onychomycosis. RESULTS: Two thousand four hundred and eighty-six subjects responded to the questionnaire. Prevalence for mycologically determined onychomycosis was 11.1% in the Icelandic population. A history of the following factors more than doubled the risk of onychomycosis: cancer (OR 3.44; 95% CI 1.15-10.35), psoriasis (OR 2.44; 95% CI 1.61-3.72), tinea pedis interdigitalis (OR 3.93; 95% CI 3.11-4.95), the moccasin form of tinea pedis (OR 4.26; 94% CI 3.34-5.45), parents with onychomycosis (OR 2.59; 95% CI 1.89-3.53), children with onychomycosis (OR 3.48; 95% CI 2.05-5.88), spouse with onychomycosis (OR 2.53; 95% CI 1.72-3.72), regular swimming activity (OR 2.57; 95% CI 2.00-3.30) and age 50 years or older (OR 2.74; 95% CI 2.19-3.42). CONCLUSIONS: Several risk factors are associated with onychomycosis. Knowledge of these risk factors is important when treating and educating patients with onychomycosis.     

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.     

Imiquimod 5% cream as pretreatment of Mohs micrographic surgery for nodular basal cell carcinoma in the face: a prospective randomized controlled study

Background Imiquimod 5% cream can reduce or clear superficial and small nodular basal cell carcinoma (BCC). It could be used as a pretreatment of Mohs micrographic surgery (MMS) to decrease defect size. Objectives To study if a pretreatment with imiquimod 5% cream decreases defect size after MMS. In addition, to study the effect on the number of Mohs stages and reconstruction time. Methods Seventy patients aged >18 years with a primary nodular BCC in the face were included. The imiquimod group used imiquimod 5% cream for 4 weeks, before MMS. The control group was treated with MMS only. Tumour and defect sizes were measured. We noted the number of Mohs stages, reconstruction time and side‐effects. Results The median percentage increase in area from tumour size at baseline to the post‐MMS defect for the imiquimod group was significantly less compared with the control group, 50% vs. 147% (P < 0·001). A tendency towards fewer Mohs stages in the imiquimod group was observed and the reconstruction time was significantly shorter in this group (P = 0·01). Conclusions Imiquimod 5% cream as pretreatment of MMS significantly reduced the tumour size in primary nodular BCC and reduced the surgical defect size. Further research is necessary to investigate cost‐effectiveness.     

Factors predictive of complex Mohs surgery cases

Abstract Background: Mohs surgery allows excision of skin cancer in a tissue-sparing fashion that minimizes recurrence risk. While the indications for Mohs surgery are well established, factors predictive of complex Mohs cases are less studied. Objective: To determine patient, tumor, and surgeon characteristics associated with complex Mohs cases. Methods: A retrospective review was performed for a 3-year period (7/2006-6/2009) to identify Mohs cases requiring ≥4 stages ("complex"), and a control population requiring ≤3 stages ("non-complex"). Surgical logs for four fellowship-trained Mohs surgeons were reviewed. Results: 77 complex cases (51 academic practice vs. 26 private practice) were compared with 154 control cases (102 academic practice vs. 52 private practice). There were no significant differences in patient age, gender, immunosuppression, academic (2.7% complex) versus private practice (3.5% complex), or surgeons' years of experience. Factors associated with complexity included: recurrent tumors (p < 0.001; odds ratio (OR) 6.88; 95% confidence interval (CI) 2.8-17); basal cell carcinoma (BCC) with infiltrative or morpheaform histology (p = 0.0019; OR 3.0; 95% CI 1.5-6.3); tumors of the nose (p = 0.0168; OR 2.05; 95% CI 1.1-3.7), especially nasal tip (p = 0.0103; OR 3.68; 95% CI 1.3-10.6) and ear (p = 0.0178; OR 3.0; 95% CI 1.2-7.9), especially helix (p = 0.00744; OR 5.9; 95% CI 1.5-22.7); tumors with pre-operative size >1 cm (p = 0.018; OR 2.0; 95% CI 1.1-3.6); and tumors involving >1 cosmetic subunit (p = 0.0072; OR 5.0; 95% CI 1.5-16.7). Complex tumors had greater post-operative area (10.6 ± 1.3 vs. 3.6 ± 0.7 cm(2); p < 0.0001), and more often required flap/graft repair (p < 0.0001; OR 6.9; 95% CI 3.7-13.1). Limitations: A retrospective study representing a single geographic area. Conclusions: Mohs cases are similar in complexity whether in academic or private practice. Recurrent/aggressive histology tumors, tumors >1 cm, and tumors on the nose or ear are more likely to prove surgically complex. Advanced knowledge of these factors may be useful pre-operatively as Mohs surgeons plan their scheduled cases.     

Assessment of risk for pelvic inflammatory disease in an urban sexual health population

OBJECTIVES: To determine the sexual and demographic risk factors for the acquisition of presumptive pelvic inflammatory disease (PID). METHODS: A retrospective, case-control study in women, who attended the Sydney Sexual Health Centre (SSHC), between April 1991 and December 1997. Logistic regression analysis was used to adjust for confounding variables. RESULTS: 741 women with PID and an equal number of controls were included. Cases were significantly younger than controls (p < 0.001). 42% of cases were born in north or South East Asia, compared with 12% of the controls (p < 0.001). The adjusted odds ratio for being born in north or South East Asia was 2.8 (95% CI 1.70-4.46), for not speaking English at home was 1.6 (95% CI 1.02-2.55), for having had previous PID was 5.9 (95% CI 3.59-9.73), and for being employed in the commercial sex industry and being born in north or South East Asia was 2.8 (95% CI 1.22-6.22). Women aged 15-19 were at considerable risk of developing PID (OR 5.3 (95% CI 2.76-10.11)). Women with previous human papillomavirus infection were significantly less likely to develop PID (OR 0.6 (95% CI 0.42-0.79)). The use of IUCDs (OR 4.5 (95% CI 2.14-9.39)), condoms (OR 1.4 (95% CI 1.03-1.87)), and not using contraception (OR 1.8 (95% CI 1.20-2.76)) was each associated with an increased risk. CONCLUSIONS: Several measures may help to reduce the burden of PID. Women should be encouraged to delay the onset of sexual activity and IUCDs should not be used in young women. Sexual health services for women whose home language is not English, and for commercial sex workers born in north or South East Asia should be improved.     

Risk factors for bullous pemphigoid in the elderly: a prospective case-control study

A rise in the incidence of bullous pemphigoid (BP) was documented recently in Europe, and the main risk factors for BP remain unknown. We conducted a multicenter case-control study to evaluate risk factors for BP. We identified 201 incident BP cases and 345 controls individually matched for age, gender, center, and place of residence (home, nursing home, or extended-care facility). We used univariate and multivariate logistic regression analyses to compare drugs used for over 3 months, comorbidities, and physical and cognitive impairments between cases and controls. Mean age of BP patients was 84.2 (±8.7) years. Factors independently associated with BP by multivariate analysis were major cognitive impairment (odds ratio (OR), 2.19; 95% confidence interval (95% CI), 1.24-3.87), bedridden condition (OR, 2.19; 95% CI, 1.23-3.89), Parkinson's disease (OR, 2.16; 95% CI, 1.09-4.27), unipolar or bipolar disorder (OR, 5.25; 95% CI, 1.21-22.86), and chronic use of spironolactone (OR, 2.30; 95% CI, 1.20-4.46) or phenothiazines with aliphatic side chains (OR, 3.70; 95% CI, 1.21-11.34). Chronic analgesic use was associated with a lower risk of BP (OR, 0.49; 95% CI, 0.30-0.81). Thus, risk factors for BP include neurological disorders, particularly dementia and Parkinson's disease, psychiatric disorders (unipolar and bipolar disorders), bedridden condition, and chronic use of several drugs.
