OBJECTIVE
Acne is a chronic inflammatory disease that involves the pilosebaceous follicle. Its pharmacological treatment involves topical and systemic medications, but a heterogeneous group of drugs may exacerbate or induce skin lesions. The aim of this study was to identify the pharmacological management and medications related to the exacerbation of skin lesions in patients diagnosed with acne.
METHODS
This was a cross-sectional study that identified the outpatient medication prescription patterns of patients with acne from a dispensing database of 8.5 million members of the Colombian Health System. Sociodemographic and pharmacological variables and the identification of prescriptions that were potentially inappropriate due to the risk of worsening acne were considered.
RESULTS
A total of 21,604 patients with acne were identified. Median age was 20.8 years (interquartile range: 17.3-27.3 years), and 60.7 percent were female. Treatment mainly involved antibiotics (79.9% of patients), especially doxycycline (66.0%), and retinoids (55.7%). A total of 17.2 percent of patients had potentially inappropriate prescriptions, predominantly progestogens with androgenic properties (8.9%). Female patients (odds ratio [OR]: 3.55; 95% confidence interval [CI]:3.24-3.90) and patients with pathologies such as systemic lupus erythematosus (OR: 18.61; 95% CI: 7.23-47.93) and rheumatoid arthritis (OR: 10.80; 95% CI: 5.02-23.23) were more likely to receive inappropriate prescriptions, and the risk increased with each year of life (OR: 1.02; 95% CI: 1.02-1.03).
LIMITATIONS
Access to medical records was not obtained to verify clinical characteristics of acne.
CONCLUSION
Patients with acne are excessively treated with systemic antibiotics, counter to clinical practice guidelines. Approximately one-fifth of these patients received some potentially inappropriate medication that could exacerbate their skin lesions.

Trenbolone is a synthetic analogue of testosterone, belonging to the nandrolone group. It has both a strong anabolic effect and a limited androgenic effect (i.e. an androgen and anabolic steroid - AAS). It is used illegally by professional or amateur athletes, who want to improve their athletic performance and appearance by increasing their muscle mass. Trenbolone, like other AASs, are harmful, with 90% of users experiencing injurious side effects. It acts systemically on the body, and as such, its side effects can manifest as symptoms from different systems. Nevertheless, its popularity is increasing. This paper reviews the current state of knowledge regarding the adverse effects of trenbolone on the nervous, reproductive, immune systems and breast, muscular and adipose tissues. However, various other adverse consequences of trenbolone utilization are observed, with severe acne and gynaecomastia affecting approximately one-third of all users, as well as excessive body hair, stretch marks, hypertension and cardiac arrhythmia. The drugs are also subject to contamination, with use frequently resulting in local inflammation at the injection site, muscle adhesions and fibrosis, nerve damage or, in extreme cases, necrosis of the injection site. Additionally, due to the lack of available knowledge on the subject, many of the effects of trenbolone use remain unknown. Moreover, the fact that multiple AASs may be used simultaneously presents a significant problem in their study. Therefore, further research is necessary to better understand the effects of AAS on the body, and to expand our currently incomplete knowledge of their functional pathways.

Genetic defects affecting steroid biosynthesis cause cortisol deficiency and differences of sex development; among them recessive mutations in the steroidogenic enzymes CYP11A1 and CYP11B, whose function is supported by reducing equivalents donated by ferredoxin reductase (FDXR) and ferredoxin. So far, mutations in the mitochondrial flavoprotein FDXR have been associated with a progressive neuropathic mitochondriopathy named FDXR-Related Mitochondriopathy (FRM), but cortisol insufficiency has not been documented. However, FRM patients often experience worsening or demise following stress associated with infections. We investigated two female FRM patients carrying the novel homozygous FDXR mutation p.G437R with ambiguous genitalia at birth and sudden death in the first year of life; they presented with cortisol deficiency and androgen excess compatible with 11-hydroxylase deficiency. In addition, steroidogenic FDXR-variant cell lines reprogrammed from three FRM patients' fibroblasts displayed deficient mineralocorticoid and glucocorticoid production. Finally, Fdxr-mutant mice allelic to the severe p.R386W human variant, showed reduced progesterone and corticosterone production. Therefore, our comprehensive studies show that human FDXR variants may cause compensated, but possibly life-threatening adrenocortical insufficiency in stress by affecting adrenal glucocorticoid and mineralocorticoid synthesis through direct enzyme inhibition, most likely in combination with disturbed mitochondrial redox balance.

Background Numerous clinical signs and symptoms are thought to be associated with insulin resistance. The purpose of this study was to examine the prevalence of insulin resistance among male medical students attending a private Saudi Arabian institution, based on clinical indications. Methods A convenient non-probability sample consisting of 241 male medical students was used to conduct cross-sectional research. Each participant had an in-person interview as well as anthropometric measurements. The interview consisted of a questionnaire that was used to assess demographic data and clinical manifestations related to insulin resistance. Results The study demonstrated the connection between a few dermatological symptoms and waist circumference as an indicator of insulin resistance. In both the high and normal waist circumference groups, acne was the most common symptom. There was no correlation found between waist circumference and psoriasis, hidradenitis suppurativa, androgenic alopecia, alopecia areata, or vitiligo. Nevertheless, as an indicator of insulin resistance, waist circumference was statistically significantly correlated with both skin tags and acanthosis nigricans. Most students had excessive day sleep, foggy brains, struggled with planning and solving problems, and had a memory that became worse in the past few years. In addition, many students feel hungry even after eating some sweets and usually have extreme thirst. Conclusion Among medical students, skin tags, acanthosis nigricans, and acne were the most prevalent dermatological manifestations. Clinicians need to be aware that skin conditions, sleep difficulties throughout the day, changes in cognition, and food cravings might all be indicators of internal changes and/or illnesses such as diabetes and prediabetes.

Polycystic ovary syndrome (PCOS) is characterized by excess androgens, ovulatory dysfunction, and polycystic ovaries. The mechanisms underlying ovulatory and metabolic disorders in PCOS remain elusive, hampering therapeutic development. Enhanced metabolic health correlates with increased microbiota gene content and microbial diversity. We aimed to explore the impact of gut microbiota and serum steroids on PCOS regulation associated with androgen excess. The fecal samples of patients with hyperandrogenic PCOS ( = 14) and control group with PCOS ( = 14) were analyzed by 16S rRNA gene sequencing. The peripheral venous blood of all subjects was collected to detect serum hormones. The association between gut microbiota and serum hormones was analyzed with the R language. Our findings reveal that the hyperandrogenic PCOS group exhibits lower richness and diversity of gut microbiota compared to the control group. Characteristic genera in PCOS patients with hyperandrogenism include , and . Five hormones, including 5β-androsterone, deoxycorticosterone, corticosterone, 11-dehydrocorticosterone, and cortexolone, emerge as potential serum biomarkers for identifying patients with hyperandrogenic-PCOS (HA-PCOS). Furthermore, a lower vitamin D3 level may act as a susceptibility factor, suggesting that vitamin D3 supplementation could serve as a potential intervention for PCOS with hyperandrogenism. Specific fecal microbiota and serum steroids may be used as characteristic markers for clinical diagnosis of hyperandrogenic-PCOS. This research enhances our understanding of the intricate interplay among hormones, gut microbiota, and hyperandrogenemia in patients with PCOS.

The role of mitochondria in steroidogenesis is well established. However, the specific effects of mitochondrial dysfunction on androgen synthesis are not fully understood. In this study, we investigate the effects of various mitochondrial and metabolic inhibitors in H295R adrenal cells and perform a comprehensive analysis of steroid and metabolite profiling. We report that mitochondrial complex I inhibition by rotenone shifts cells toward anaerobic metabolism with a concomitant hyperandrogenic phenotype characterized by rapid stimulation of dehydroepiandrosterone (DHEA, 2 h) and slower accumulation of androstenedione and testosterone (24 h). Screening of metabolic inhibitors confirmed DHEA stimulation, which included mitochondrial complex III and mitochondrial pyruvate carrier inhibition. Metabolomic studies revealed truncated tricarboxylic acid cycle with an inverse correlation between citric acid and DHEA production as a common metabolic marker of hyperandrogenic inhibitors. The current study sheds light on a direct interplay between energy metabolism and androgen biosynthesis that could be further explored to identify novel molecular targets for efficient treatment of androgen excess disorders.

46,XX Differences of Sex Development outside congenital adrenal hyperplasia: pathogenesis, clinical aspects, puberty, sex hormone replacement therapy and fertility outcomes.
The term 'differences of sex development' (DSD) refers to a group of congenital conditions that are associated with atypical development of chromosomal, gonadal, and/or anatomical sex. DSD in individuals with a 46,XX karyotype can occur due to fetal or postnatal exposure to elevated amount of androgens or maldevelopment of internal genitalia. Clinical phenotype could be quite variable and for this reason these conditions could be diagnosed at birth, in newborns with atypical genitalia, but also even later in life, due to progressive virilization during adolescence, or pubertal delay. Understand the physiological development and the molecular bases of gonadal and adrenal structures is crucial to determine the diagnosis and best management and treatment for these patients. The most common cause of DSD in 46,XX newborns is congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, determining primary adrenal insufficiency and androgen excess. In this review we will focus on the other rare causes of 46,XX DSD, outside CAH, summarizing the most relevant data on genetic, clinical aspects, puberty and fertility outcomes of these rare diseases.

Review
Prenatal-onset androgen excess leads to abnormal sexual development in 46,XX individuals. This androgen excess can be caused endogenously by the adrenals or gonads or by exposure to exogenous androgens. The most common cause of 46,XX disorders/differences in sex development (DSD) is congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, comprising >90% of 46,XX DSD cases. Deficiencies of 11β-hydroxylase, 3β-hydroxysteroid dehydrogenase, and P450-oxidoreductase (POR) are rare types of CAH, resulting in 46,XX DSD. In all CAH forms, patients have normal ovarian development. The molecular genetic causes of 46,XX DSD, besides CAH, are uncommon. These etiologies include primary glucocorticoid resistance (PGCR) and aromatase deficiency with normal ovarian development. Additionally, 46,XX gonads can differentiate into testes, causing 46,XX testicular (T) DSD or a coexistence of ovarian and testicular tissue, defined as 46,XX ovotesticular (OT)-DSD. PGCR is caused by inactivating variants in , resulting in glucocorticoid insensitivity and the signs of mineralocorticoid and androgen excess. Pathogenic variants in the gene lead to aromatase deficiency, causing androgen excess. Many genes are involved in the mechanisms of gonadal development, and genes associated with 46,XX T/OT-DSD include translocations of the ; copy number variants in , , , , , and , and sequence variants in , , , , , , and . Progress in cytogenetic and molecular genetic techniques has significantly improved our understanding of the etiology of non-CAH 46,XX DSD. Nonetheless, uncertainties about gonadal function and gender outcomes may make the management of these conditions challenging. This review explores the intricate landscape of diagnosing and managing these conditions, shedding light on the unique aspects that distinguish them from other types of DSD.

BACKGROUND/AIM
Atopic dermatitis (AD) is an inflammatory, pruritic, noncontagious, chronic relapsing skin disease. Skin barrier abnormalities, excessive T helper 2 activity, and immune dysregulation are held responsible. Androgens have a negative effect on the integrity of the epidermal skin barrier, while estrogen has a positive effect. We aimed to investigate whether hormones make a difference between healthy children and children with AD during minipuberty.
MATERIALS AND METHODS
A total of 96 infants (postnatal 4-13 weeks), 48 diagnosed with AD and 48 controls, were included. Each group consisted of 23 girls (47.9%) and 25 boys (52.1%). Anthropometric examinations and hormone measurements were compared.
RESULTS
The two groups, having similar age, sex, body mass index, and weight-for-length standard deviation scores, were compared. Serum free thyroxine (FT4) levels were found to be lower and insulin-like growth factor binding protein-3 (IGFBP3) levels were found to be higher in children with AD (p < 0.001 and p = 0.038, respectively). In girls with AD, estradiol, FT4, and insulin-like growth factor-1 (IGF-1) levels were found to be lower, but thyroid-stimulating hormone (TSH) levels were found to be higher (p = 0.023, p < 0.001, p = 0.038, and p = 0.034, respectively). In boys with AD, the FT4 level was found to be lower (p = 0.023). Serum FT4 and TSH levels were within normal reference ranges in all comparisons.
CONCLUSION
Especially in girls with AD, decreased estradiol and IGF-1 levels were observed compared to the controls during minipuberty. In the logistic regression model, decreased levels of serum estradiol, dehydroepiandrosterone sulfate, FT4, and IGF-1, and increased levels of IGFBP3 were associated with an increased likelihood of exhibiting atopic dermatitis.
