Acne is a multifactorial and common disorder among young people and a frequent reason for dermatology consultation. When moderate-to-severe acne is not responsive to conventional treatments, oral isotretinoin is a very effective solution. However, there are cases in which this treatment fails to produce the expected results. In this case, an 18-year-old male patient with acne, unresponsive to traditional acne therapies, experienced only a partial benefit from oral isotretinoin. Endocrinology consultation and hormonal work-up revealed androgen metabolism anomalies suggestive of a non-classical form of congenital adrenal hyperplasia due to 21-hydroxylase deficiency. In this case report, the authors discuss when to suspect, how to diagnose, and how to manage similar cases.

BACKGROUND
gene mutations are responsible for more than 95% of Congenital Adrenal Hyperplasia (CAH) disorders with autosomal recessive inheritance. Most of these pathogenic mutations originate from the , a neighboring pseudogene with 98% homology, due to unequal crossing over or gene conversion events. Mutation identification of the gene could be beneficial for accurate diagnosis and outcome prediction.
METHODS
Twelve unrelated patients with CAH diagnosis were recruited for genetic counseling. To ensure distinct amplification of the gene rather than its pseudogene, the complete sequence of the gene was amplified through two overlapping fragments by specific primers. The entire sequences were screened by direct Sanger sequencing using new sequencing primers.
RESULTS
Only two pathogenic point mutations were identified. The c.293-13C>G, also known as In2G, and the c.955C>T mutations were found in 37.5 and 33.3% of alleles, respectively. One patient showed homozygous gene deletion. We also reviewed recent reports on gene mutations in Iran.
CONCLUSION
Evaluating the ethnicity-specific gene mutation data is significant for populations with diverse ethnic groups including the Iranian population. Although several common mutations have been reported as causative mutations among CAH patients, identifying only two common point mutations in Fars province would help prioritize exon sequencing and reduce the cost and time of genotyping.

BACKGROUND
Feline pulmonary Langerhans cells histiocytosis (PLCH) is a rare disorder that results in progressive respiratory failure secondary to pulmonary parenchymal infiltration with Langerhans cells (LCs). A diagnosis of PLCH is proposed based on the clinical features and pathological findings and confirmed based on the infiltrating histiocytic cells. There are few documented cases of feline PLCH, and this case report of PLCH in an African Lion could present new information and aspects of this feline histiocytic disease.
CASE PRESENTATION
An African lion at Hohhot Zoo showing severe hyporexia and dyspnea with subsequent mental depression and emaciation died of exhaustion after a 35-day course of illness. Empirical treatment did not have a significant effect. An autopsy revealed that the lungs were enlarged and hardened due to infiltrative lesions, with many yellowish-white foci in all the lobes and sections. Furthermore, the kidneys were atrophied and had scattered grayish-white lesions on the surface. At the same time, congestion was widely distributed in various locations, including the liver, subcutaneous loose connective tissues, serosal surface and other tissues and organs. Histologically, proliferative histiocytic cells (PHCs) were scattered in the alveolar cavities, bronchioles and submucosa of bronchioles, with evident cellular and nuclear pleomorphism, and thus the alveolar septa were obliterated. The histopathological changes in other organs included chronic sclerosing glomerulonephritis, proliferated Kupffer cells in the liver, adrenal edema and interstitial connective tissue hyperplasia, as well as atrophy of the small intestines and spleen. Furthermore, immunohistochemical analysis results were strongly positive for CD1a, vimentin, S100 and E-cadherin in the membrane or cytoplasm of PHCs, supporting an LC phenotype.
CONCLUSIONS
Here, we present a rare pulmonary Langerhans cell histiocytosis case in an African lion.

Review
Adrenocortical insufficiency, also known as adrenal insufficiency (AI), is an endocrine disorder characterized by inadequate production of adrenal hormones, including glucocorticoids and mineralocorticoids (MCs). The condition can be categorized as primary, secondary, or tertiary AI, depending on the location of the defect. Classical symptoms of AI include weakness, fatigue, abdominal pain, tachycardia, hypotension, electrolyte imbalances, and hyperpigmentation. In children, the most common cause of AI is classical congenital adrenal hyperplasia, which results from a deficiency in the 21-hydroxylase enzyme. The 21-hydroxylase enzyme produces all steroids, such as cortisol and aldosterone. AI management primarily involves hormone replacement therapy, typically with oral hydrocortisone and MC supplementation. However, the administration of hydrocortisone to pediatric patients presents challenges related to the lack of available dose-appropriate formulations. Historically, crushed or split adult tablets were used for the pediatric treatment of AI, although this poses an increased risk of under- or overtreatment. Inadequate dosing in the pediatric population can adversely affect growth, development, and metabolic health. Alkindi Sprinkle is a pediatric-specific hydrocortisone oral granule preparation that manages cortisol levels to help facilitate accurate therapeutic dosing. Alkindi offers several advantages, including accurate dosing, taste masking, and ease of administration. The present investigation describes AI, the management of AI, and the treatment of pediatric AI using Alkindi Sprinkle, including clinical efficacy.

17α-hydroxylase deficiency is a type of congenital adrenocortical hyperplasia that is typically diagnosed in childhood or adolescence. It manifests as hypertension with gonadal dysfunction as the primary symptom. We herein report 17α-hydroxylase/17,20-lyase deficiency (17OHD) diagnosed at the age of 45 years. The patient presented with hypertension, irregular menstruation, and hyperaldosteronism. The clinical manifestations of 17OHD vary based on the specific variant pattern of CYP17A1. In this case, the variant was c.157_159 TCC del p. Phe53del, which has been frequently reported in Japan. The enzymatic deficiency due to this variant is partial, leading to a delay in making a correct diagnosis.

Giant Bilateral Adrenal Myelolipomas in a Non-Compliant Patient with Congenital Adrenal Hyperplasia.The American Journal of Case Reports Apr 2024BACKGROUND 21-hydroxylase deficiency, an essential enzyme for glucocorticoid and mineralocorticoid synthesis, is the cause of congenital adrenal hyperplasia (CAH) in...
BACKGROUND 21-hydroxylase deficiency, an essential enzyme for glucocorticoid and mineralocorticoid synthesis, is the cause of congenital adrenal hyperplasia (CAH) in more than 95% of cases. It is an autosomal recessive disorder encoded by the CYP21A2 gene, categorized into classical forms, which encompass the salt-wasting (SW) and simple virilizing (SV) forms, as well as the nonclassical form (NC). The aim of medical treatment is to replace missing glucocorticoids and, if necessary, mineralocorticoids, while also reducing elevated adrenal androgens. CASE REPORT We present the case of a 42-year-old woman with CAH who discontinued therapy during adolescence and was admitted to hospital with fatigue, nausea, and severe abdominal pain. A CT scan showed an extreme enlargement of the adrenal glands. Laboratory tests revealed elevated levels of 17-hydroxyprogesterone and other adrenal androgens, along with normal plasma metanephrine levels. Decreased morning cortisol levels suggested partial adrenal insufficiency requiring glucocorticoid replacement therapy. Due to the development of several serious complications and clinical deterioration, the multidisciplinary team recommended bilateral removal of masses measuring 300×250×200 mm on the right side and 250×200×200 mm on the left side. Histological and immunochemical examination confirmed the presence of giant myelolipomas with adrenal cortex hyperplasia. CONCLUSIONS Adrenal tumors, particularly myelolipomas, have a higher prevalence in patients with CAH. Our case report provides further evidence of the suspected link between non-compliant CAH therapy and the development of myelolipomas, along with promotion of their pronounced growth.

Despite the availability of life-saving corticosteroids for 70 years, treatment for adrenal insufficiency is not able to recapitulate physiological diurnal cortisol secretion and results in numerous complications. Gene therapy is an attractive possibility for monogenic adrenocortical disorders such as congenital adrenal hyperplasia; however, requires further development of gene transfer/editing technologies and knowledge of the target progenitor cell populations. Vectors based on adeno-associated virus are the leading system for direct gene delivery but have limitations in targeting replicating cell populations such as in the adrenal cortex. One strategy to overcome this technological limitation is to deliver the relevant adrenocortical gene to a currently targetable organ outside of the adrenal cortex. To explore this possibility, we developed a vector encoding human 21-hydroxylase and directed expression to the liver in a mouse model of congenital adrenal hyperplasia. This extra-adrenal expression resulted in reconstitution of the steroidogenic pathway. Aldosterone and renin levels normalized, and corticosterone levels improved sufficiently to reduce adrenal hyperplasia. This strategy could provide an alternative treatment option for monogenic adrenal disorders, particularly for mineralocorticoid defects. These findings also demonstrate, when targeting the adrenal gland, that inadvertent liver transduction should be precluded as it may confound data interpretation.

BACKGROUND AND OBJECTIVE
Hirsutism is a common endocrine disorder and its etiology varies from benign and idiopathic disorders to serious malignant diseases. Hirsutism creates negative impact on quality of life and considerable effects on fertility. Our objective was to determine the various causes of hirsutism in women presenting at two endocrine clinics.
METHOD
This cross-sectional study was conducted at Baqai Institute of Diabetology and Endocrinology, Karachi and at Jinnah hospital, Lahore from August 2020 to December 2021 women between 12-45 years of age with complains of hirsutism were included in the study. Severity of Hirsutism was evaluated using modified Ferriman-Gallwey score (FG). Patients with modified FG score of 8 or more were considered having hirsutism.
RESULTS
The study had 113 patients with a mean age of 15.50+7.29 years with 89% having moderate hirsutism (FG score 16-25). Polycystic ovaries was the most common cause of hirsutism. Common sites for hirsutism included back (83%), arms (74%), buttocks (70%), and upper abdomen (47%). High BMI (p-value <0.01) and high Dehydroepiandrosterone levels were positively associated with the severity of hirsutism (p-value of 0.006.).
CONCLUSION
The various causes of hirsutism identified were polycystic ovaries, followed by idiopathic, thyroid dysfunction, congenital adrenal hyperplasia, and hyperprolactinemia; therefore, all women presenting with hirsutism should be evaluated for potential serious and curable etiologies, before embarking on a treatment plan.

PURPOSE
To investigate the incidence of nephrolithiasis in a cohort of children with congenital adrenal hyperplasia (CAH), and to study if there is an association with the metabolic control of the disease.
METHODS
This study was designed as a multicenter 1 year-prospective study involving 52 subjects (35 males) with confirmed molecular diagnosis of CAH due to 21-hydroxylase deficiency (21-OHD). Each patient was evaluated at three different time-points: T0, T1 (+6 months of follow-up), T2 (+12 months of follow up). At each follow up visit, auxological data were collected, and adrenocorticotrophic hormone (ACTH), 17-hydroxyprogesterone (17-OHP), Δ4-androstenedione, dehydroepiandrosterone sulfate (DHEAS) serum levels, and urinary excretion of creatinine, calcium, oxalate and citrate were assayed. Moreover, a renal ultrasound was performed.
RESULTS
The incidence of nephrolithiasis, assessed by ultrasound was 17.3% at T0, 13.5% at T1 and 11.5% at T2. At T0, one subject showed nephrocalcinosis. In the study population, a statistically significant difference was found for 17-OHP [T0: 11.1 (3.0-25.1) ng/mL; T1: 7.1 (1.8-19.9) ng/mL; T2: 5.9 (2.0-20.0) ng/mL, p < 0.005], and Δ4-androstenedione [T0: 0.9 (0.3-2.5) ng/mL; T1: 0.3 (0.3-1.1) ng/mL; T2: 0.5 (0.3-1.5) ng/mL, p < 0.005] which both decreased over the follow up time. No statistically significant difference among metabolic markers was found in the group of the subjects with nephrolithiasis, even if 17-OHP, DHEAS and Δ4-androstenedione levels showed a tendency towards a reduction from T0 to T2. Principal component analysis (PCA) was performed to study possible hidden patterns of associations/correlations between variables, and to assess the trend of them during the time. PCA revealed a decrease in the amount of the variables 17-OHP, Δ4-androstenedione, and ACTH that occurred during follow-up, which was also observed in subjects showing nephrolithiasis.
CONCLUSIONS
our data demonstrated that children affected with 21-OHD can be at risk of developing nephrolithiasis. Additional studies are needed to clarify the pathogenesis and other possible risk factors for this condition, and to establish if regular screening of kidney ultrasound in these patients can be indicated.
