Isotretinoin and mental health in adolescents: Australian consensus

Acne is a common condition among adolescents and has the potential to negatively impact on the psychological well‐being of those who suffer from it. In particular, depression and suicidal ideation are more common in adolescents with acne. Successful treatment of acne can improve the quality of life and reduce levels of anxiety and depression in these individuals. The current treatment of choice for severe or refractive acne is isotretinoin, a retinoid. While the possible causal association between isotretinoin and mental illness remains a controversial topic, a recent systematic review has presented evidence to support this relationship. In light of this evidence, a group of dermatologists and psychiatrists have collaborated to develop these recommendations to aid the safe prescribing of isotretinoin in adolescents. These clinical suggestions are aimed at practitioners in both disciplines to increase awareness of the current evidence in support of the association between isotretinoin and adolescent depression.     

Heredity of acne in Korean patients

Acne is a chronic inflammatory disease of the pilocebaceous unit that presents with various spectrum and severity. Genetic backgrounds and environmental factors are also considered to be relevant, but few studies have focused on Korean patients. A cross‐sectional epidemiologic study on family history of Korean acne patients was performed to analyze family history of acne, and to compare the severity and characteristics of acne in association with family history. A total of 221 patients were enrolled, 98 male (44.3%) and 123 female (55.7%). Patients were grouped as patients with (A+) or without (A‐) family history of acne. In a second analysis, patients with any experience of acne treatment were evaluated. Severity of acne was measured with Burton's grading system and Korean Acne Grading System (KAGS). Female patients had a higher tendency to have family history than males (P = 0.002). Group A+ had statistically significant earlier onset of acne (P = 0.002). In inexperienced patients, patients with family history showed a relatively earlier onset (P = 0.084). This study confirmed the role of heredity in acne. Family history of acne is associated with earlier onset of the disease, and more non‐inflammatory lesions.     

What's new in acne? An analysis of systematic reviews published in 2011–2012

This review summarizes important clinical developments in acne vulgaris identified from 17 systematic reviews published between February 2011 and August 2012. Regarding causes, Demodex mites have been shown to be associated with both acne vulgaris and rosacea, although it is unclear if their eradication improves either disease. Some weak evidence has emerged that suggests a possible link between dairy produce and acne, which warrants further research. With reference to the effects of acne, there is good evidence that acne negatively affects quality of life, self‐esteem and mood in adolescents. Acne is also associated with an increased risk of anxiety, depression and suicidal ideation, highlighting the importance of asking patients with acne directly about psychological issues in order to identify those who might benefit from early psychiatric support. Regarding treatment, there seems to be no additional benefit to using higher strengths of benzoyl peroxide, and lower strengths such as 2.5% have fewer side effects. Despite earlier concerns of increased mortality in those using topical tretinoin for skin cancer prevention, a systematic review on this topic has not found any convincing evidence of a link between such non‐cutaneous events and once‐daily application of 0.02–0.05% tretinoin. Combined oral contraceptives are of benefit in both inflammatory and non‐inflammatory acne. Current surveys suggest that implementation of the pregnancy prevention programme for isotretinoin may not be stringent, and a high level of monitoring and audit is recommended. Ablative and non‐ablative laser resurfacing for the treatment of acne scars may be beneficial, but further studies with a longer follow‐up period are required.     

Acne analysis,grading and computational assessment methods: an overview

Introduction: This paper presents a comprehensive review of acne grading and measurement. Acne is a chronic disorder of the pilosebaceous units, with excess sebum production, follicular epidermal hyperproliferation, inflammation and Propionibacterium acnes activity. Most patients are affected with acne vulgaris, which is the prevalent type of acne. Acne vulgaris consists of comedones (whitehead and blackhead), papules, pustules, nodules and cysts. Objectives: To review and identify the issues for acne vulgaris grading and computational assessment methods. To determine the future direction for addressing the identified issues. Methods: There are two main methods of assessment for acne severity grading, namely, lesion counting and comparison of patient with a photographic standard. For the computational assessment method, the emphasis is on computational imaging techniques. Results: Current acne grading methods are very time consuming and tedious. Generally, they rely on approximation for counting lesions and hence the assessment is quite subjective, with both inter and intra‐observer variability. It is important to accurately assess acne grade to evaluate its severity as this influences treatment selection and assessment of response to therapy. This will further help in better disease management and more efficacious treatment. Conclusion: Semi‐automated or automated methods based on computational imaging techniques should be devised for acne grade assessment.     

Descriptive epidemiology of acne vulgaris in the community

Acne is a common skin condition. No universally accepted standardized classification system for acne vulgaris exists, although there is a strong need for it Thus, the clinical definition of acne has been unclear in many studies. The reported prevalence of acne varies from 35 to over 90% of adolescents at some stage. In some studies the prevalence of comedones approaches 100% in both sexes during adolescence. The prevalence of acne varies between sexes and age groups, appearing earlier in females than in males, possibly reflecting the earlier onset of puberty. There is a greater severity of acne in males than in females in the late teens, which is compatible with androgens being a potent stimulus to sebum secretion. The prevalence of acne at a given age has been shown to be highly dependent on the degree of sexual maturity. Acne commonly shows a premenstrual increase in women. Some studies have detected seasonal variability in acne vulgaris, with the colder months associated with exacerbation and the warmer months showing improvement. Other studies have not confirmed these findings. Several studies that have investigated the psychosocial impact of acne have had conflicting results. The prevalence of severe acne has decreased over the past 20 years due to improved treatment. The general prevalence figure for acne may be confounded by treatment and this factor needs to be accounted for when collecting data.     

Current treatments of acne: Medications,lights, lasers,and a novel 650‐μs 1064‐nm Nd: YAG laser

The treatment of acne, especially severe acne, remains a challenge to dermatologists. Therapies include retinoids, antibiotics, hormones, lights, lasers, and various combinations of these modalities. Acne is currently considered a chronic rather than an adolescent condition. The appropriate treatment depends on the patient and the severity of disease. The purpose of this study was to review current therapies for acne of all severities and to introduce the 650‐μs 1064‐nm laser for the treatment of acne.     

Anxiety, depression, and nature of acne vulgaris in adolescents

BACKGROUND: The reported prevalence of acne in adolescence is variable; improved treatment may have modified its prevalence and severity; acne has been related to psychiatric morbidity for many years. METHODS: Two thousand six hundred and fifty-seven high school students were examined, and adolescents with acne were interviewed about the subject of acne vulgaris. The severity of acne was graded using the Global Acne Grading System (GAGS). The Hospital Anxiety and Depression (HAD) scale was evaluated for one of every two subjects with acne (n = 308) and for the same number of sex-matched control subjects (n = 308) to determine the prevalence of depression and anxiety. RESULTS: Six hundred and fifteen of the subjects (23. 1%) were determined to have acne. Acne prevalence in girls and boys was 16.1% and 29.2%, respectively (P < 0.001). Two hundred and twenty-five (15.8%) of 1424 boys and only 109 (8.8%) of 1233 girls had moderate or severe/very severe acne (P < 0.001), but the GAGS scores in the groups of boys and girls with acne were not significantly different. The acne and control groups showed no significant differences in the HAD anxiety and depression subscale scores. The HAD anxiety subscale scores of girls were significantly higher than those of boys in the acne group. The severity of acne was not correlated with the HAD anxiety or depression subscale scores. CONCLUSIONS: Acne results in higher anxiety in adolescent girls. Although acne and moderate/severe acne are more common in adolescent boys, the severity of acne was found to be similar in boys and girls with acne. Adolescent girls are more vulnerable than boys to the negative psychological effects of acne.

Prevalence of acne vulgaris in Chinese adolescents and adults: a community-based study of 17,345 subjects in six cities

Acne vulgaris is a common skin condition in adolescents. The prevalence of acne is thought to vary between ethnic groups and countries. A large-scale community-based study was performed in six cities in China to determine the prevalence and possible risk factors for acne in the Chinese population. A total of 17,345 inhabitants were included in this study. Of these, 1,399 were found to have acne. No acne was found in subjects under 10 years of age, and only 1.6% in the 10-year-old group had acne. Prevalence then increased rapidly with age, up to 46.8% in the 19-year-old group. After that, it declined gradually with age. Acne was rare in people over 50 years of age. In subjects in their late teens and 20s, acne was more prevalent in males, while in those over 30 years of age it was more prevalent in females. In subjects with acne, 68.4% had mild; 26.0% had moderate and 5.6% had severe acne. In adult acne, persistent acne was much more common (83.3%) than late-onset acne (16.7%). Smoking and drinking were found to be associated with adolescent acne, while no association was found between diet and acne. These results suggest that the prevalence of acne in the Chinese population is lower than that in Caucasian populations, and that adult acne is not uncommon in Chinese subjects.

Prevalence of scars and “mini‐scars”, and their impact on quality of life in Japanese patients with acne

There have been very few studies on the prevalence and severity of acne scars in Japanese patients. The aim of the present study was to investigate the prevalence of acne scars and their impact on the quality of life (QOL) in Japanese acne patients. Acne scars were classified as mini‐scars (atrophic scars of ≥0.5 and <2 mm in diameter) atrophic scars (≥2 mm in diameter), and hypertrophic scars. The severity of acne and acne scars were evaluated. The background of patients and their QOL in relation to acne were assessed. Of 240 subjects, 218 (90.8%) had scars. All patients with scars had mini‐scars; 61.2% and 14.2% of 240 had atrophic scars and hypertrophic scars, respectively. Severe scarring was found in patients who had experienced severe acne symptoms, although 15.0% of patients with scars had experienced only mild acne symptoms. The total Dermatology Life Quality Index score was significantly higher in patients with scars than in patients without scars (5.9 ± 4.4 vs 4.2 ± 4.1). Almost all the patients had small atrophic scars with a diameter of 0.5 or more and less than 2 mm, which we have termed “mini‐scars”. Acne scars had a negative impact on patient QOL. Early initiation of treatment is recommended to avoid acne scars.

Evaluation of 25‐hydroxy vitamin D levels and disease severity in patients with acne vulgaris

Acne vulgaris is a multifactorial skin disorder. Many etiological factors are speculated to contribute to the pathogenesis of acne, one of these is vitamin D deficiency. Previous studies reported contradictory results about serum 25 hydroxy vitamin D (25‐OH vitamin D) levels, its association with acne, some claimed that acne lesion might improve with vitamin D supplementation. We aimed to assess serum 25‐OH vitamin D levels in acne patients, identify their relation with disease severity in a larger study group. The study included 134 acne patients, 129 controls. Acne disease severity was identified with Global Acne Grading Scale (GAGS) scores. Serum 25‐OH vitamin D levels were measured in all groups. Serum 25‐OH vitamin D levels were significantly lower in acne patients than in controls (P < .001). The prevalence of vitamin D deficiency was significantly higher in acne group than in control group (77.6% vs 63.9%; P = .041). There was a negative‐strong statistically significant correlation detected between serum 25‐OH vitamin D levels and GAGS scores in patient group (P < .001; r = −.910). According to these results, we claim that evaluating serum 25‐OH vitamin D levels in acne patients, vitamin D supplementation as a treatment option may be a consideration for further studies.     

Acne: prevalence, perceptions and effects on psychological health among adolescents in Aydin, Turkey

Background Acne vulgaris is a common disease among adolescents and known to have adverse effects on psychological status. Methods A cross‐sectional study was conducted on 600 participants by means of a questionnaire designed for this study in high school students. In addition, an objective evaluation of acne in participants was undertaken. The questionnaire consisted of questions about acne, General Health Questionnaire (GHQ) and Rosenberg Self‐Esteem Scale (RSES). Results Five hundred and sixty‐three questionnaires out of 600 were answered and 550 adolescents who gave permission for examination were evaluated. The study population consisted of 303 girls and 260 boys between the ages 13 and 19, and the mean age was 15.24 ± 1.05 years. Acne prevalence was 63.6% with 29.2% non‐inflammatory and 34.4% inflammatory acne. It was more prevalent and severe in boys than in girls. Not the objective but the subjective severity of acne and opinion that one could benefit from acne treatment was found to be related to anxiety, depression and self‐esteem. Factors implicated among causes of acne were food, bad skin hygiene and hormones in decreasing frequency. Forty‐eight per cent of adolescents expect a maximum duration of 4 weeks for treatment. Conclusion Despite the high prevalence of acne, there is still much deficiency of knowledge and wrong beliefs about acne. This indicates that there is an urgent need for education about etiopathogenesis, potential complications and importance of effective treatment for acne. Effective treatment may make significant contributions for the mental health of adolescent and as well as adult populations.     

Systemic inflammatory reactions and extracutaneous manifestations of acne vulgaris

166 patients suffering from acne of different severity were examined with regard to associated systemic manifestations. 74 of the patients showed acne conglobata, 12 acne tetrade, 11 acne fulminans, and 69 acne papulopustulosa. Subjective symptoms like weakness, fever, and arthralgia, as well as unspecific serological inflammatory parameters and internal symptoms were taken into consideration. Acne papulopustulosa was not associated with any internal symptoms. Such extracutaneous reactions were observed, however, in severe forms of acne as in acne tetrade or acne conglobata (41% vs 17%). Acne fulminans revealed musculoskeletal manifestations and severe inflammatory signs in the blood. The high rate of kidney involvement with severe inflammatory types of acne was alarming. Three patients developed on acute glomerulonephritis, which evolved into a chronic form in two patients.     

Self‐Reported Acne Severity,Treatment, and Belief Patterns across Multiple Racial and Ethnic Groups in Adolescent Students

Abstract: Acne vulgaris is a common condition among adolescents regardless of age, gender, and race. We compare the frequency, severity, help‐seeking behavior, treatment, and beliefs about acne among students based on race, ethnicity, gender, and age. Anonymous surveys were administered to 1,214 students aged 10–19 years of varied gender, race, and ethnicity in public middle and high schools in New Jersey. Results showed the frequency and severity of acne were high (76% and 65%, respectively) and more prevalent in white compared to non‐white respondents (RR = 1.13, 95% CI = 1.04–1.24 and RR = 1.22, 95% CI = 1.09–1.37, respectively), and also in older compared to younger ages (RR = 1.24, 95% CI = 1.17–1.32 and RR = 1.43, 95% CI = 1.32–1.55, respectively). The majority of respondents (83%) reported never having seen a physician for their acne; however, those reporting acne of some severity were more likely to have seen a physician compared with those who did not report acne (21% vs. 8%, p < 0.001). Blacks who reported mild or moderate severity of acne were more likely to have seen a health professional compared to white respondents with same the acne severity (RR = 3.63, 95% CI = 2.06–6.37 and RR = 3.06, 95% CI = 2.02–4.65, respectively). Conversely, Hispanic respondents with mild or moderate acne were less likely to have seen a health professional compared to whites with the same acne severity (RR = 0.56, 95% CI = 0.35–0.89 and RR = 0.47, 95% CI = 0.26–0.86, respectively). Beliefs about external factors affecting acne also varied by race and ethnicity. In conclusion, the severity, frequency, and beliefs about acne all play a role in help‐seeking behaviors, which vary to a significant extent by race and ethnicity.     

Heredity: a prognostic factor for acne

BACKGROUND: The role of heredity in acne severity and therapeutic response remains unclear. OBJECTIVE: A prospective epidemiologic study was performed to compare clinical and evolutive features of acne and response to treatment in 151 patients with acne with (A+) or without (A-) family history of acne. METHODS: A+ and A- patients were compared on clinical and therapeutic criteria. A+ patients were then distributed into subgroups (M+, F+, M+F+) following the origin of family history (father: F, mother: M). RESULTS: The clinical profile was similar in the A+ and A- populations. Acne occurred earlier and more often before puberty in the A+ population, in which oral treatments and relapse after isotretinoin were more frequent. Retentional lesions (number and extent) were more important in the M+ and M+F+ populations. CONCLUSION: This study confirms the importance of heredity as a prognostic factor for acne. Family history of acne is associated with earlier occurrence of acne, increased number of retentional lesions and therapeutic difficulties.     

Acne vulgaris in early adolescent boys. Correlations with pubertal maturation and age

To assess the prevalence and severity of acne vulgaris in young adolescent boys, we studied 219 black and 249 white boys in fifth through ninth grades in Cincinnati, Ohio. The mean age was 12.2 +/- 1.4 years, with a range of 9 to 15 years. Pubertal maturation was scored as Tanner pubic hair stages (PH I to V) and pubertal stages (PS I to IV) that included testicular volume assessment. Acne was scored by number of comedonal (open plus closed comedones) and inflammatory (papules plus pustules) lesions. Comedonal and inflammatory lesions were analyzed separately and evaluated both as numerical scores and as grades (1, less than or equal to 10 lesions; 2, 11 to 25 lesions; and 3, greater than or equal to 26 lesions). Grades 2 and 3 were considered clinically significant acne. Acne became progressively more severe with advancing maturity. Mean acne scores correlated better with PS and pubic hair than with age. Black subjects were more mature than white subjects. Black boys in PSI and II had significantly more comedones than white boys; white boys had significantly more inflammatory lesions at PS I and III. Clinically significant comedonal acne was already present in PS I and occurred in 100% of boys in PS IV. In contrast, no boys at PS I and only 50% at PS IV had significant inflammatory acne. Midfacial acne dominated. We concluded that acne prevalence and severity correlate well with advancing pubertal maturation in young adolescent boys. Comedonal acne was more frequent and severe than inflammatory disease. Awareness of the extent and severity of acne in preadolescents and young adolescents may ultimately provide rationale for early intervention and thus prevention of severe acne vulgaris.     

Most common patterns of acne in male adolescents: a population‐based study

Background Acne vulgaris is a common skin disease affecting more than 85% of adolescents and often continuing into adulthood. Population‐based studies to assess the patterns and severity of acne have not been achieved. Objectives The aim of this study was to assess the most common patterns of facial and trunk acne in young (18‐year‐old) men in a representative sample of male adolescents in a city in southern Brazil and to investigate the severity of inflammatory and non‐inflammatory lesions in these individuals. Methods In Brazil, military service is compulsory for all males. Every adolescent male must report to his military service headquarters to submit to a medical screening examination. The study included 2201 adolescents, each of whom underwent a skin examination conducted by a dermatologist to identify and quantify all non‐inflammatory (comedones) and inflammatory (papules, pustules, and nodules) lesions. Results Non‐inflammatory lesions (comedones) were observed on 1487 individuals, and inflammatory lesions (papules and pustules) were noted on 1497 individuals. The most common patterns of facial acne were the full‐face, bilateral malar and frontal mentonian distributions. Conclusions This is the first population‐based study to evaluate patterns of acne. Facial involvement was very prevalent, and the frontal region was found to dominate patterns of distribution of acne vulgaris. Comedonian acne of the face was much more intense and affected the entire face. In inflammatory facial acne, the majority of the study subjects exhibited up to five lesions in the region under study.     

Acne: prevalence and relationship with dietary habits in Eskisehir,Turkey

Background Acne vulgaris is a common disease affecting adolescents. There is not comprehensive data on acne prevalence in the Central Anatolia Region in particular. Etiology of acne is not clarified yet. Acne might be related to environmental factors. There is increasing evidence supporting acne and diet relationship. Objectives The aim of the study was to determine the acne prevalence in adolescents in the city of Eskisehir, located in the Central Anatolia, Turkey in addition to evaluate factors affecting acne and its relationship with dietary habits. Methods A cross‐sectional study was conducted on 2300 participants aged 13–18 years. The participants were asked to complete a questionnaire form consisting information about acne and a questionnaire form consisting information about dietary habits (The Adolescent Food Habits Checklist). In addition an objective evaluation of acne was determined. Results The mean age of students with acne was 15.10 ± 1.53. The current acne prevalence was 60.7%. Although 21% of the participants had severe acne (grade 3–4) and 25% developed sequelaes, only 11.5% of all participants consulted a doctor. The participants without acne had healthier dietary habits than participants with acne (P < 0.05). Frequent fat intake (OR = 1.39, 95% CI: 1.06–1.82), frequent sugar intake (OR = 1.30, 95% CI: 1.05–1.60), frequent eating sausages, burgers (OR = 1.24, 95% CI: 1.03–1.48), frequent eating pastries, cakes (OR = 1.20, 95% CI: 1.01–1.43) were associated with increased risk for acne. Conclusions Acne prevalence is high among adolescents in Eskisehir but the rate of consulting doctor is low. Increasing public awareness is critical for convincing adolescents to seek medical help earlier. Acne was related with dietary habits. Fat, sugar and fast food consumption is found to be positively correlated with acne prevalence.
