The debate around the construct validity of complex posttraumatic stress disorder (CPTSD) has begun to examine whether CPTSD diverges from posttraumatic stress disorder (PTSD) when it co‐occurs with the diagnosis of borderline personality disorder (BPD). The present study (a) examined the construct validity of CPTSD through a latent class analysis of a non–treatment‐seeking sample of young trauma‐exposed adults and (b) characterized each class in terms of trauma characteristics, social emotions (e.g., shame, guilt, blame), and interpersonal functioning. A total of 23 dichotomized survey items were chosen to represent the symptoms of PTSD, CPTSD, and BPD and administered to 197 trauma‐exposed participants. Fit statistics compared models with 2–4 latent classes. The four‐class model showed the best fit statistics and clinical interpretability. Classes included a “high PTSD+CPTSD+BPD” class, characterized by high‐level endorsement of all symptoms for the three diagnoses; a “moderate PTSD+CPTSD+BPD” class, characterized by endorsement of some symptoms across all three diagnoses; a “PTSD” class, characterized by endorsement of the ICD‐11 PTSD criteria; and a “healthy” class, characterized by low symptom endorsement overall. Pairwise comparisons showed individuals in the high PTSD+CPTSD+BPD class to have the highest levels of psychological distress, traumatic event history, adverse childhood experiences, and PTSD symptoms. Shame was the only social emotion to significantly differ between the classes, p = .002, η² = .16. The findings diverge from the literature, indicating an overlap of PTSD, CPTSD, and BPD symptoms in a non–treatment‐seeking community sample. Further, shame may be a central emotion that differentiates between presentation severities following trauma exposure.  相似文献

The authors estimated the number of clinically recognized pregnancies that occurred annually from 1981 to 1991 in the United States by type of outcome and by race. Estimates of the numbers of livebirths, induced abortions, ectopic pregnancies, and fetal deaths were obtained by using data from the Centers for Disease Control and Prevention in Atlanta, Georgia. The number of spontaneous abortions was estimated by using previously published, age-specific rates. More than 67 million pregnancies occurred during the study period. Overall, 62.5% of these pregnancies resulted in livebirths, 21.9% in legal induced abortions, 13.8% in spontaneous abortions, 1.3% in ectopic pregnancies, and 0.5% in fetal deaths. These data can be used to provide denominators for the calculation of a variety of pregnancy outcome-specific rates.  相似文献

Post-burn hallux varus is an extremely rare condition. A 22-year-old male, with a history of campfire burns in childhood, presented with secondary hallux varus of the left great toe. Surgical correction included medial soft tissue release, metatarsophalangeal joint arthrodesis, two-pin fixation of bones, metatarsophalangeal joint capsulorrhaphy, and coverage of the skin defect with a "Z" plasty of the skin and split thickness skin grafting. Follow up 20 months later showed satisfactory results.  相似文献

BACKGROUND: As skin cancer education programmes directed to children and adolescents continue to expand, an epidemiological basis for these programmes is necessary to target efforts and plan for further evaluation. AIMS: To summarise the epidemiological evidence on sun exposure during childhood and adolescence and melanoma risk. METHODS: A literature review was conducted using Medline (1966 to December 2004) to identify articles relating to sun exposure and melanoma. The review was restricted to studies that included sun exposure information on subjects 18 years of age or younger. RESULTS: Migrant studies generally indicate an increased melanoma risk in individuals who spent childhood in sunny geographical locations, and decreasing melanoma risk with older age at arrival. Individuals who resided in geographical locations close to the equator or close to the coast during childhood and/or adolescence have an increased melanoma risk compared to those who lived at higher latitudes or never lived near the coast. The intermittent exposure hypothesis remains controversial; some studies indicate that children and adolescents who received intermittent sun exposure during vacation, recreation, or occupation are at increased melanoma risk as adults, but more recent studies suggest intermittent exposure to have a protective effect. The majority of sunburn studies suggest a positive association between early age sunburn and subsequent risk of melanoma. CONCLUSION: Future research efforts should focus on: (1) clarifying the relation between sun exposure and melanoma; (2) conducting prospective studies; (3) assessing sun exposure during different time periods of life using a reliable and quantitative method; (4) obtaining information on protective measures; and (5) examining the interrelations between ability to tan, propensity to burn, skin type, history of sunburns, timing and pattern of sun exposure, number of nevi, and other host factors in the child and adolescent populations.  相似文献

Introduction:

Over centuries, virginity has been given social, religious and moral importance. It is widely believed as a state of a female who has never engaged in sexual intercourse, and her hymen is intact. Hymenoplasty for torn hymen is carried out not only for the sake of cultural and religious traditions but also for the social status and interpersonal relationships.

Materials and Methods:

2.5 cm long and 1 cm wide four vaginal mucosal flaps were raised from the anterior vaginal wall just behind labia minora. Two flaps were based proximally, and their two opposing flaps were based distally. These flaps were overlapped in a crisscross fashion and were sutured with 5/0 Polyglactin (Vicryl®) sutures leaving no area raw. The donor area was closed primarily. When some remains of a torn hymen were found, one to three vaginal mucosal flaps were added to its remains as per the need for reconstruction.

Results:

We operated upon 11 patients. In nine cases, the hymen was reconstructed with four flaps. In remaining two, it was reconstructed from the remains using vaginal mucosal flaps. All flaps healed without any infection or disruption. Sutures got absorbed in 25-35 days. In all cases, this newly constructed barrier broke with only moderate pressure at the time of penetrative sex serving the purpose of the surgery completely.

Conclusion:

Erasing evidence of the sexual history simply by ‘Surgical Revirgination’ is extremely important to women contemplating marriage in cultures where a high value is placed on virginity.KEY WORDS: Hymen, hymenoplasty, revirgination, vagina, vaginal mucosal flaps, virginity  相似文献

We conducted a study to determine prevalence of HPV types in oropharyngeal cancers in the United States and establish a prevaccine baseline for monitoring the impact of vaccination. HPV DNA was extracted from tumor tissue samples from patients in whom cancer was diagnosed during 1995–2005. The samples were obtained from cancer registries and Residual Tissue Repository Program sites in the United States. HPV was detected and typed by using PCR reverse line blot assays. Among 557 invasive oropharyngeal squamous cell carcinomas, 72% were positive for HPV and 62% for vaccine types HPV16 or 18. Prevalence of HPV-16/18 was lower in women (53%) than in men (66%), and lower in non-Hispanic Black patients (31%) than in other racial/ethnic groups (68%–80%). Results indicate that vaccines could prevent most oropharyngeal cancers in the United States, but their effect may vary by demographic variables.  相似文献

Objectives. Recently, several state indoor tanning laws, including age restrictions, were promulgated to reduce indoor tanning among minors. We examined the effects of these laws on adolescent indoor tanning.Methods. We used nationally representative data from the 2009 and 2011 national Youth Risk Behavior Surveys (n = 31 835). Using multivariable logistic regression, we examined the association between state indoor tanning laws and indoor tanning among US high school students.Results. Female students in states with indoor tanning laws were less likely to engage in indoor tanning than those in states without any laws. We observed a stronger association among female students in states with systems access, parental permission, and age restriction laws than among those in states without any laws. We found no significant association among female students in states with only systems access and parental permission laws or among male students.Conclusions. Indoor tanning laws, particularly those including age restrictions, may be effective in reducing indoor tanning among female high school students, for whom rates are the highest. Such reductions have the potential to reduce the health and economic burden of skin cancer.Skin cancer is the most common cancer in the United States. Approximately 3.5 million cases of nonmelanoma skin cancers are treated annually, while more than 60 000 melanomas are diagnosed annually.1,2 In addition, skin cancer poses a substantial economic burden, with annual direct medical costs of treatment estimated at $1.7 billion in 2004.3 During the past decade, while most cancers decreased, melanoma increased, especially among young adult women.4 Indoor tanning is thought to be partially responsible for this increase.4–6 Indoor tanning before age 35 years increases the risk of melanoma by 59%,5,7 and indoor tanning before age 25 years increases the risk of basal cell carcinoma by 40% and squamous cell carcinoma by 102%.8 Despite these known health risks, indoor tanning is common among adolescents—6.2% of male high school students and 20.9% of female high school students engaged in indoor tanning in 2011.9In recent years, several states have enacted laws restricting youth access to indoor tanning and laws aimed at reducing consumers’ risk, including facility and operator responsibilities, safety and equipment standards, enforcement authority, and penalties.10 Previous studies that were primarily focused on youth access laws found poor compliance rates among tanning facilities for parental permission laws.11–13 In addition, such laws were ineffective in reducing indoor tanning among adolescents.14,15 Since these earlier studies were conducted, the number of states implementing youth access laws, particularly age restrictions, has increased substantially.16 Although some evidence has suggested that age restrictions may reduce access to indoor tanning among minors,17 no national or international studies have examined the effects these laws have on adolescent indoor tanning behavior. We examined the association between state indoor tanning laws, including age restrictions, and indoor tanning among high school students.  相似文献

BACKGROUND: Recent studies have shown a negative association between body mass index (BMI) and prostate-specific antigen (PSA), a commonly used serum marker for the detection and diagnosis of prostate cancer. We have examined the association between several anthropometric measures and PSA in a nationally representative sample of men. METHODS: We analyzed data from the 2001-2004 National Health and Nutrition Examination Survey. Participants in this study were men ages >or=40 years without previously diagnosed prostate cancer who had PSA measured. Height, weight, waist circumference, BMI, triceps skinfold, subscapular skinfold, and calculated total body water were examined categorically by quintiles using multiple linear regression models. All tests of significance were two sided. RESULTS: Among white men, we report a trend for decreasing PSA with increasing weight, BMI, waist circumference, triceps skinfold thickness, and calculated total body water. Among Mexican American men, we found a trend for decreasing PSA with increasing BMI, and among black men we found a trend for decreasing PSA with increasing triceps thickness. None of the interaction terms between race/ethnicity and any of the anthropometric measures were statistically significant. Controlling for age and race/ethnicity in the multiple linear regression model, we found moderate declines in PSA with a 1 SD increase in BMI [5.9% decrease (95% confidence interval, -9.0% to -2.8%) in geometric mean PSA per 5.2-unit increase], weight [5.9% decline (-8.8% to -2.8%) per 17.7-kg increase], waist circumference [6.6% decline (-9.4% to -3.6%) per 13.4-cm increase], triceps skinfold [5.4% decline (-8.9% to -1.8%) per 6.4-mm increase], and calculated total body water [5.7% decline (-8.9% to -2.4%) per 6.5-liter increase]. CONCLUSION: Our population-based, nationally representative results expand the validity of previous studies on obesity and PSA. Higher weight, BMI, waist circumference, triceps skinfold, and total body water are associated with moderately lower PSA values. A prospective study is needed to verify whether this association affects the accuracy of the PSA test in obese men.  相似文献

OBJECTIVES: This study sought to determine adherence of physicians to tuberculosis (TB) screening guidelines among foreign-born persons living in the United States who were applying for permanent residency. METHODS: Medical forms of applicants from 5 geographic areas were reviewed, along with information from a national physician database on attending physicians. Applicant and corresponding physician characteristics were compared among those who were and were not correctly screened. RESULTS: Of 5739 applicants eligible for screening via tuberculin skin test, 75% were appropriately screened. Except in San Diego, where 11% of the applicants received no screening, most of the inappropriate screening resulted from the use of chest x-rays as the initial screening tool. CONCLUSIONS: Focused physician education and periodic monitoring of adherence to screening guidelines are warranted.  相似文献
