RESUMEN
Background: Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine-metabolic disorder in women of reproductive age. Diagnosis is based on the evidence-based international guideline 2018 and the Rotterdam Consensus to classify PCOS phenotypes. This study aims to characterize the biodemographic, clinical, metabolic, and reproductive variables and their relationship with PCOS phenotypes in a population from the Ecuadorian Andes. Methodology: A cross-sectional study was conducted with a non-random consecutive sample of 92 women who attended the outpatient gynecology and endocrinology clinic at the Hospital of the Technical University of Loja (UTPL)-Santa Inés, Loja, Ecuador, between January 2022 and July 2023. Descriptive statistics, mean calculations, standard deviation, parametric and nonparametric tests, odds ratios (OR), confidence intervals (CI), and p-values were employed. Results: The average age was 22 ± 3.4 years, with a predominantly mestizo, urban, single, highly educated, and medium-high socioeconomic level population. It was identified that phenotypes A + B are at a higher risk of developing oligomenorrhea and hypertriglyceridemia compared to phenotypes C + D, with statistically significant differences (p < 0.05). Furthermore, in terms of reproductive variables, phenotypes A + B exhibit a significantly higher frequency of elevated anti-Müllerian hormone (AMH) compared to phenotypes C + D, also with statistical significance (p < 0.05). Conclusions: The classical phenotypes A and B of PCOS are the most common in Ecuadorian Andean women and carry a higher risk of insulin resistance, anovulation, metabolic disorders, and elevated triglyceride levels compared to phenotypes C and D. Ethnic diversity and sociocultural habits influence the prevalence and clinical manifestations of these phenotypes.
RESUMEN
Ovarian steroid cell tumors are rare, representing less than 0.1% of all ovarian neoplasms. Among the myriad causes of hirsutism, ovarian tumors account for 1% of the reported cases. We present the case of a 49-year-old parous postmenopausal woman who sought medical attention for hirsutism for 2 years. This case illustrates the unusual and interesting connection between rare ovarian pathology and the clinical manifestation of hirsutism in a postmenopausal patient. Her ultrasonography and MRI showed a right adnexal mass of solid-cystic consistency with thin septations. Her laboratory workup revealed high levels of total testosterone of 256 ng/ml (8.4-48.1ng/ml) and free testosterone of 7.36 pg/ml (0.2-4.1 pg/ml), while DHEAS - 234 µg/dl (35.4-256 µg/dl) and CA125 - 15.8U/L (0.0-35 U/L) were in the normal range. She underwent exploratory laparotomy with a total abdominal hysterectomy and oophorectomy. Histopathological examination and immunohistochemistry conclusively established the presence of a steroid cell tumor, specifically classified as "Not Otherwise Specified"(NOS), in the right ovary.
RESUMEN
INTRODUCTION: Hirsutism is a prevalent condition among women and represents a primary clinical feature of polycystic ovary syndrome (PCOS). AREAS COVERED: Our study aims to address the principal challenges associated with this hyperandrogenic manifestation in PCOS women. Our narrative review based on the available indexed literature explored the complexities of establishing mFG cutoff values for various ethnic groups, investigated hirsutism during peri- and postmenopausal stages, and examined the role of oxyandrogens. EXPERT OPINION: Hirsutism may have a negative impact on the quality of life and on the mental health, being associated with anxiety and depression. Future perspectives for its diagnosis include the use of artificial intelligence and the consideration of the distress caused by excessive hair growth.

OBJECTIVE: Spironolactone (SPL) has been used to manage hyperandrogenic manifestations in women with polycystic ovary syndrome (PCOS), but data on the risk of hyperkalemia in this population are scarce. The aim of this study was to evaluate the incidence of hyperkalemia in women with PCOS using SPL in the long term. DESIGN: Single-centre retrospective study. PATIENTS: Inclusion and analysis of 98 treatment periods in 78 women with PCOS (20 of whom were duplicates, returning after treatment interruption for a mean of 38 months) who received SPL for a minimum of 12 months and had at least three measurements of potassium levels over time. MEASUREMENTS: Clinical and hormonal profiles before and during SPL treatment. RESULTS: Mean age was 29.1 (SD: 9.6) years, and body mass index was 32.2 (SD: 8.1) kg/m². Nine patients had diabetes, and 22 had prediabetes. SPL was used in combination with combined oral contraceptive pills in 55 participants and progestin-only pills/long-acting reversible contraception in 28; metformin was added in 35, and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers in 15. Median SPL dose was 100 (range: 50-150) mg. A total of 327 serum potassium measurements were obtained (84 pre-exposure and 243 postexposure). Four potassium measurements were above the reference range before exposure and 19 during exposure. All potassium measurements above the reference range during follow-up were classified as mild hyperkalemia (5.1-5.5 mEq/L). CONCLUSIONS: The present findings suggest that women with PCOS, without kidney or heart disease, using SPL combined with hormonal contraception for managing clinical hyperandrogenism have a low incidence of hyperkalemia and well-tolerated minor adverse effects.

RESUMEN
ABSTRACT Objective The aim of this study was to evaluate the efficacy of a self-assessment questionnaire for hirsutism using the latest cutoff values recommended by the Endocrine Society (ES) for Latin-American women and by the European Society for Human Reproduction and Embryology (ESHRE). Subject and methods Female premenopausal outpatients (n = 188) completed a self-assessment questionnaire, scoring hair presence across the nine areas evaluated by the modified Ferriman-Gallwey (mFG) scale. The results were compared with clinician-assessed scores rated independently by two trained physicians. Scores in the Hirsuta questionnaire, derived from self-assessment of five areas of the mFG scale, were also evaluated. Results The ethnic composition of the sample was as follows: 23.1% white, 25.8% black, 48.9% mixed, and 2.1% other backgrounds (Indigenous, Asian). The participants had age and BMI of (mean ± standard deviation) 33.7 ± 9.9 years and 29.8 ± 7.21 kg/m2, respectively. The most common areas of excessive hair growth were the chin, upper and lower abdomen, and thighs. Relative to clinician-assessed mFG scores, self-assessed mFG scores had an accuracy of 80% using ES criteria for hirsutism diagnosis, with a sensitivity of 95.45%, specificity of 56.25%, positive predictive value of 30.10%, and negative predictive value of 98.40%. Self-assessed mFG had lower accuracy (71%) for diagnosing hirsutism when the ESHRE criteria were applied. Conclusions Self-assessed mFG had low specificity, limiting its application. The results of this study do not support the use of the self-assessed mFG or Hirsuta scores for diagnosing hirsutism in a clinical setting, although both scoring systems may be useful for screening hirsutism in epidemiological studies.
RESUMEN
The clinical syndrome of the pituitary pars intermedia dysfunction (PPID) is the most common endocrinopathy of older horses. This syndrome is characterized by several clinical and pathological changes, which are usually associated with adenomas of the pars intermedia (PI) of the pituitary gland. The aim of this work is to describe five cases of pituitary adenoma of the PI associated with PPID in horses, addressing its clinical and pathological aspects. The horses had a mean of 22 years of age. The main clinical signs were hirsutism and paresis of hind limbs, and at post mortem examination all horses had hirsutism, and a nodule in the pituitary gland, which was histologically characterized as an adenoma of PI (5/5). Furthermore, two horses had gross lesions suggestive of chronic laminitis. Moreover, there was intense parasitism of Sarcocystis neurona (2/5), Strongylus vulgaris (1/5), Parascaris equorum (1/5), Draschia megastoma (1/5), and Klossiella equi (1/5).
A síndrome clínica da disfunção da pars intermedia da hipófise (PPID) é a endocrinopatia mais comum em cavalos idosos. Essa síndrome é caracterizada por várias alterações clínicas e patológicas, geralmente associadas a adenomas da pars intermedia (PI) da hipófise. O objetivo deste trabalho é descrever cinco casos de adenoma hipofisário de PI associado a PPID em equinos, abordando seus aspectos clínicos e patológicos. Os cavalos apresentaram média de 22 anos de idade. Os principais sinais clínicos incluíam hirsutismo e paresia dos membros pélvicos, e no exame post mortem todos os equinos apresentavam hirsutismo e um nódulo na glândula pituitária, que foi histologicamente caracterizada como um adenoma de PI (5/5). Além disso, dois cavalos tinham lesões macroscópicas sugestivas de laminite crônica. Ainda, havia intenso parasitismo de Sarcocystis neurona (2/5), Strongylus vulgaris (1/5), Parascaris equorum (1/5), Draschia megastoma (1/5) e Klossiella equi (1/5).

Hirsutism is defined as the presence of terminal hair with male pattern distribution in women. While in the general population, hirsutism affects around 4-11% of women, it is the main manifestation of hyperandrogenism in women with polycystic ovary syndrome (PCOS), with a prevalence estimated at 65-75%. Hirsutism in PCOS is associated with both androgen excess and individual response of the pilosebaceous unit to androgens. The modified Ferriman-Gallwey (mFG) scoring system has been widely used in clinical practice to visually score excessive terminal hair, thus standardizing hirsutism evaluation and facilitating data comparison. Although a universal mFG score cutoff would be useful for comparisons, ethnic variations, as well as skin type and other factors, should be considered when evaluating hirsutism in distinct populations. In turn, androgen levels, measured by conventional techniques, have been shown to correlate poorly with the severity of hirsutism. Indeed, while most women with PCOS and hirsutism also have higher than reference values for serum androgen levels, some of them may not present with biochemical hyperandrogenism, representing a challenge to the diagnosis of PCOS. In this article, we critically review this not uncommon condition in women with PCOS presenting with hirsutism but normal androgen levels.
RESUMEN
Spironolactone is a drug, similar in structure to aldosterone and acts as an aldosterone receptor antagonist with an anti-androgenic effect. This drug has proven to be useful in several dermatological entities, however its use has not been well explored. Its use in diseases such as acne has opened the door to the possibility of new therapies depending on the clinical manifestations of the patients, as well as its possible to use it as a first line treatment. Other diseases associated with the use of spironolactone where its effects have been shown to be useful are hidradenitis suppurativa, hirsutism, and female pattern androgenetic alopecia. In this review, we discuss the use of spironolactone in different skin diseases that are common in our environment, dosage according to different studies, treatment recommendations and adverse effects; all of the above mentioned in order to use this drug in a daily clinical practice.

SUMMARY: Cushing's syndrome is an endocrine disorder that causes anovulatory infertility secondary to hypercortisolism; therefore, pregnancy rarely occurs during its course. We present the case of a 24-year-old, 16-week pregnant female with a 10-month history of unintentional weight gain, dorsal gibbus, nonpruritic comedones, hirsutism and hair loss. Initial biochemical, hormonal and ultrasound investigations revealed hypokalemia, increased nocturnal cortisolemia and a right adrenal mass. The patient had persistent high blood pressure, hyperglycemia and hypercortisolemia. She was initially treated with antihypertensive medications and insulin therapy. Endogenous Cushing's syndrome was confirmed by an abdominal MRI that demonstrated a right adrenal adenoma. The patient underwent right laparoscopic adrenalectomy and anatomopathological examination revealed an adrenal adenoma with areas of oncocytic changes. Finally, antihypertensive medication was progressively reduced and glycemic control and hypokalemia reversal were achieved. Long-term therapy consisted of low-dose daily prednisone. During follow-up, despite favorable outcomes regarding the patient's Cushing's syndrome, stillbirth was confirmed at 28 weeks of pregnancy. We discuss the importance of early diagnosis and treatment of Cushing's syndrome to prevent severe maternal and fetal complications. LEARNING POINTS: Pregnancy can occur, though rarely, during the course of Cushing's syndrome. Pregnancy is a transient physiological state of hypercortisolism and it must be differentiated from Cushing's syndrome based on clinical manifestations and laboratory tests. The diagnosis of Cushing's syndrome during pregnancy may be challenging, particularly in the second and third trimesters because of the changes in the maternal hypothalamic-pituitary-adrenal axis. Pregnancy during the course of Cushing's syndrome is associated with severe maternal and fetal complications; therefore, its early diagnosis and treatment is critical.
RESUMEN
Spironolactone is an economical potassium-sparing diuretic with an anti-androgenic effect and a good safety profile. Our experience suggests that this diuretic is underexploited in dermatology even though there is evidence supporting its use in several skin conditions. When prescribed for acne in female patients (level 1-2 evidence; strength of recommendation, B), for example, it can reduce the need for antibiotics and possibly isotretinoin. Other diseases in which spironolactone is potentially useful are hidradenitis suppurativa and female androgenetic alopecia. We discuss the indications for spironolactone, dosing in dermatology, precautions to consider, and adverse effects. We also review new evidence that stresses the safety of long-term therapy and supports the use of this drug without the need for complementary testing in young women. We think that spironolactone merits a place among the medications commonly used in routine clinical practice.

Se estudió una paciente de 47 años de edad con antecedentes de buena salud, sin antecedentes atópicos personales ni familiares, que acude a la consulta de endocrinología por presentar aumento del vello corporal con dos años de evolución. Al examen físico se le constató rubicundez facial, escudo pubiano masculino, predominio de la cintura escapular sobre la cintura abdominal e hipertrofia de 3,5 cm del clítoris. Referente a los exámenes complementarios presentó un marcado aumento de la testosterona en sangre así que se le practicó una histerectomía con doble anisectomía y los resultados de la biopsia fueron: un tumor benigno de células de Leydig. Se concluyó que se trataba de un Síndrome de Cooke-Apert-Gallais por un tumor productor de testosterona en el ovario(AU)
A study was conducted of a female 47-year-old patient with a history of good health and no personal or family atopic antecedents, who attends endocrinology consultation due to increased growth of body hair of two years' evolution. Physical examination revealed facial reddishness, a male pubic shield, predominance of the scapular waist over the abdominal waist, and 3.5 cm hypertrophy of the clitoris. Complementary tests found a marked increase in blood testosterone, which led to the performance of hysterectomy with double adnexectomy. The result of the biopsy was benign Leydig cell tumor. The final diagnosis was Cooke-Apert-Gallais syndrome due to a testosterone-producing tumor in the ovary(AU)

Background Inherited severe insulin resistance syndromes (SIRS) are rare and can be caused by mutations in the insulin receptor gene (INSR). Case presentation A 12-year-old Jamaican girl with a BMI of 24.4 kg/m2 presented with polyuria and polydipsia. A diagnosis of T1DM was made in view of hyperglycaemia (18 mmol/l), and elevated Hba1C (9.9%), and insulin therapy was initiated. Over the next 2 years, she developed hirsutism and acanthosis nigricans, and had minimal insulin requirements with frequent post-prandial hypoglycaemia. In view of this, and her strong family history suggestive of a dominantly inherited type of diabetes, the diagnosis was revisited. Targeted next-generation sequencing (NGS) of the patient's monogenic diabetes genes was performed. What is new? NGS revealed a novel heterozygous missense INSR variant, NM_000208.3:c.3471T>G, p.(His1157Gln), confirming a diagnosis of Type A SIRS. Conclusions Type A SIRS can be difficult to differentially diagnose due to the variable phenotype. Features of insulin resistance may be absent at initial presentation and may develop later during pubertal progress. Awareness of the clinical features and comprehensive genetic testing are essential to identify the condition.

OBJECTIVE: Follow-up studies of girls with premature adrenarche have reported the development of polycystic ovary syndrome, insulin resistance, and dyslipidemia and a propensity to cardiovascular disease. The aim of this study was to analyze the presence of these conditions in patients previously treated at the Universidade Federal do Triângulo Mineiro. METHODS: A total of 130 medical records reported premature adrenarche. One hundred and twenty-two patients were invited to participate, of whom 54 accepted; 34 patients were selected, as they had reached their final height. Anthropometric, blood glucose, insulin, and lipid and hormonal profile (LH, FSH, estradiol, 17α-OH-progesterone, androstenedione, dehydroepiandrosterone sulfate, testosterone) data were obtained, the HOMA-IR index was calculated, and pelvic ultrasonography was performed. To characterize polycystic ovary syndrome and metabolic syndrome, the Rotterdam and International Diabetes Federation criteria, respectively, were used. Data were analyzed according to measures of dispersion, frequency and correlations of interest. RESULTS: The age of the participants ranged from 15.2 to 28.2 years/months; 23.5% of the patients were overweight, 11.8% were obese, 29.4% had a large waist circumference, and 8.8% were hypertensive. None of the patients had altered glucose levels, and insulin levels and HOMA-IR were elevated in 29.4% and 38.2% of the participants, respectively; 14.7% of the patients exhibited acanthosis nigricans. The lipid profiles of the participants were variable, and one patient (2.9%) had metabolic syndrome. Polycystic ovary syndrome was found in 41.2% of patients. CONCLUSION: The percentage of patients with polycystic ovary syndrome who also had overweight, obesity and insulin resistance corroborates the literature data about the need for follow-up aiming at interventions, especially for conditions associated with cardiometabolic risk.

Clinical case: a girl of 7 ½ years who consulted for early pubarche without thelark, with a percentile size of 75 for a genetic target size in the 10th percentile, overweight with a 90th percentile BMI, and normal blood pressure. The biochemical study showed high levels of androgens: testosterone: 7.2 ng/dL, androstenedione of 5.1 ng / ml, 17OHP: 15 ng / dL with low normal DHEAS (0.26 ug/ml), Plasma Renin Activity normal low: 0.22 ng/mL/h. Initial imaging study showed a bone age of 10 years 6 months and normal abdominal and pelvic ultrasound. Molecular study showed no pathogenic variants in the CYP21A2 gene (21 Hydroxylase). With a probable diagnosis of non-classical congenital adrenal hyperplasia (HSRNC) and no known mutation, he started treatment with hydrocortisone (12 mg/m2). At 8.7 years, pubertal development begins and braking begins with LHRH analogues, which are administered for 18 months. Despite the treatment, signs of virilization and elevation of androgens (testosterone up to 130 ng/ml) are progressively accentuated, which do not diminish when trying different corticosteroid schemes. MRI of the abdomen and pelvis shows the normal adrenal glands and a solid nodular image of 2.1 x 1.6 cm in the right ovary (Figure 2), later demonstrated with pelvic ultrasound (Figure 2). Right laparoscopic oophorectomy was performed, whose biopsy demonstrated a Leydig cell tumor. One month after surgery, all androgenic levels were normalized, so the gradual suspension of corticosteroids began. Conclusion: Although HSRNC is the most frequent pathological cause of early pubarche, when it is associated with progressive clinical and biochemical hyperandrogenism despite adequate treatment and without pathogenic variants in the CYP21A2 gene, even with high levels of 17OHP, other causes should be considered, specifically, androgen producing tumors.
Caso clínico: niña de 7½ años que consulta por pubarquia precoz sin telarquia, con talla en percentil 75 para una talla objetivo genético en percentil 10, sobrepeso con IMC percentil 90 y presión arterial normal. El estudio bioquímico mostró niveles elevados de andrógenos: testosterona: 7,2 ng/dL, androstenediona de 5,1 ng/ml, 17OHP: 15 ng/dL con DHEAS normal baja (0,26 ug/ml), Actividad de Renina Plasmática normal baja: 0.22 ng/ mL/h. Estudio de imágenes inicial mostró una edad ósea de 10 años 6 meses y ecografía abdominal y pelviana normales. Estudio molecular no mostró variantes patogénicas en el gen CYP21A2 (21 Hidroxilasa). Con diagnosticó probable de hiperplasia suprarrenal congénita no clásica (HSRNC) y sin mutación conocida,inició el tratamiento con hidrocortisona (12 mg/m2). A los 8.7 años comienza desarrollo puberal y se inicia frenación con análogos de LHRH, los cuales se administran por 18 meses. A pesar del tratamiento se acentúan progresivamente los signos de virilización y hayelevación de los andrógenos (testosterona hasta 130 ng/ml), que no disminuyen intentando diferentes esquemas de corticoides. Se realiza RM de abdomen y pelvis que muestra las glándulas suprarrenales normales y una imagen nodular sólida de 2.1 x 1.6 cm en el ovario derecho (Figura 2), demostrada posteriormente con Ecografía pelviana (Figura 2). Se realiza ooforectomía derecha por vía laparoscópica, cuya biopsia demostró un tumor de células de Leydig. Un mes después de la cirugía, se normalizan todos los niveles androgénicos por lo que se inició la suspensión gradual de los corticoides. Conclusión: Aunque la HSRNC es la causa patológica más frecuente de la pubarquia precoz, cuando se asocia con un hiperandrogenismo clínico y bioquímico progresivo a pesar de un tratamiento adecuado y sin variantes patógenicas en el gen CYP21A2, incluso con niveles elevados de 17OHP, otras causas deben ser consideradas, específicamente tumores productores de andrógenos.

Esta revisión fue realizada con el fin de evaluar nuestros resultados de laboratorio así como aquellos de la literatura que constituyen, a nuestro entender, aportes significativos en el síndrome de ovarios poliquísticos (SOP). Nuestro especial énfasis será presentar las limitaciones de las metodologías empleadas por nuestro grupo, comparativamente a las reportadas por otros investigadores. La determinación de andrógenos, en particular de Testosterona (TT), es quizá la de mayor complejidad dado que los resultados con los diferentes inmunoensayos empleados en nuestro medio producen resultados muy variables por los diferentes métodos y aún entre laboratorios que usan la misma metodología. La técnica de referencia es la cromatografía líquida en tándem con espectrometría de masa (LC-MSMS), de difícil aplicación en laboratorios de análisis clínicos debido a su alto costo y la imposibilidad de resolver numerosas muestras. En estudios previos demostramos que de los métodos habitualmente usados para evaluar la TT circulante, solo en 2 inmunoensayos los resultados obtenidos fueron satisfactoriamente validados indirectamente según el criterio del Consenso de los Centros para el Control y Prevención de Enfermedades (CDC, USA) contra LC-MSMS, los cuales fueron comparables a dicha metodología con niveles superiores a 0,5 ng/ml. El SOP puede presentar factores de riesgo aumentados para la enfermedad cardiovascular y la diabetes II. Estos factores no están debidamente categorizados en función de los distintos fenotipos del SOP. Se evaluarán los principales analitos empleados con este objetivo y los nuevos que aporten elementos de mayor especificidad en este sentido
This review was performed in order to evaluate our laboratory results as well as those of the literature that constitute, in our opinion, significant contributions in these pathophysiologies. Our special emphasis will be on presenting the limitations of the methodologies used by our group, compared to those reported by other researchers. The determination of androgens, in particular Testosterone (TT), is perhaps the most complex since the results with the different immunoassays used in our environment produce very variable results by the different methods and even between laboratories that use the same methodology. The reference technique is LC-MSMS, difficult to apply in clinical analysis laboratories because of its high cost and the inability to solve numerous samples. In previous studies, we demonstrated that, in comparison to LC-MSMS with the usual methods for evaluating circulating TT, the results obtained in only 2 immunoassays were satisfactorily validated indirectly according to the criteria of CDC against LC-MSMS, which were comparable to that methodology with levels higher than 0.5 ng/ml. PCOS may have increased risk factors for cardiovascular disease and diabetes II. These factors are not properly categorized according to the different phenotypes of PCOS. The main analytes used for this purpose will be evaluated and new ones that contribute elements of greater specificity in this sense

Hirsutism is a common condition, being present in about 5-15% of women. It is characterized by the growth of terminal hair in a pattern typical for men, like as hair growth in upper lip, chin, cheek and lower and upper abdomen. Not infrequently, hirsutism is followed by other signs of hyerandrogenism such as alopecia, acne, and seborrhea. The current study evaluated the association between a self-reported history of hirsutism and oligo-amenorrhea during reproductive age and the presence of several comorbidities in women after menopause. A total of 1057 women were investigated in a cross-sectional study, and information on the age at menarche, menstrual history, complaints about excessive hair growth, and disease development was obtained. Participants from the study were postmenopausal women aged >55 y who attended ac primary care service at least once during the 24-month period. Exclusion criteria included the presence of cognitive impairment and/or communication difficulties. Main outcomes were the presence of comorbidities after menopause. The prevalence of comorbidities was significantly higher in women with a history of hirsutism and/or oligo-amenorrhea [OR = 1.6 (95% CI 1.1-2.4), p = 0.002] or isolated hirsutism [OR 2.0 (95% CI 1.3-3.2), p = 0.004]. The prevalence of stroke, angina or myocardial infarction, cardiac failure, chronic obstructive pulmonary disease, and osteoarthritis were significantly higher in postmenopausal women who had experienced hirsutism and/or oligomenorrhea (p < 0.03). Limitations of the study came from the absence of a clear differentiation between hirsutism and hypertrichosis. According our results, the presence of hirsutism and oligo-amenorrhea during the female reproductive period may indicate susceptibility to important diseases at old age.
RESUMEN
Introducción: el síndrome de ovarios poliquísticos es un cuadro clínico caracterizado por la presencia de ovarios con pequeños quistes, amenorrea, hirsutismo y obesidad. Objetivo: proporcionar criterios diagnósticos vigentes y tendencias de tratamiento integral mediante una revisión sistemática de la literatura que permita un direccionamiento de los criterios médicos en atención a las mujeres con síndrome de ovario poliquístico. Métodos: estudio descriptivo retrospectivo, realizado mediante búsquedas en base de datos electrónicos como, Pubmed, Google Scholar, Cochrane Library, Science Direct y Elsevier. Se consultaron 25 artículos publicados desde el año 2011 para realizar esta revisión en torno al síndrome de ovario poliquístico, los cuales presentan evidencias científicas, en relación a la utilidad de la misma con contribuciones en el diagnóstico y manejo terapéutico de esta patología. Resultados: el abordaje diagnóstico implica ciertas dificultades en relación con el momento de presentación de los síntomas y la tendencia actual es considerar como un diagnóstico de exclusión, empleándose los cuatros fenotipos propuestos en Rotterdam. El estudio encontró que los cambios en el estilo de vida, la reducción del peso, dieta, ejercicios, medicina alternativa, tratamientos cosméticos, prevención de factores epigenéticos, la terapia quirúrgica y farmacológica contribuyen a mejorar la calidad de vida y sintomatología en las pacientes afectadas con esta entidad nosológica. Conclusión: el síndrome de ovario poliquístico sigue siendo una enfermedad con diagnóstico de exclusión, pero la tendencia actual es investigar la hormona antimulleriana como predictor de esta enfermedad.

Introduction: the polycystic ovarian syndrome (PCOS) is a clinical condition characterized by the presence of ovaries with small cysts, amenorrhea, hirsutism and obesity. Objective: Provide current diagnostic criteria and comprehensive treatment trends, through a systematic review, which allows addressing the medical criteria in care for women with polycystic ovarian syndrome (PCOS). Methods: A retrospective descriptive study was conducted by searching electronic database as Pubmed, Google Scholar, Cochrane Library, Science Direct and Elsevier. Twenty-five articles published since 2011 are addressed for this review on SOP, which present scientific evidence, in relation to its utility with contributions in the diagnosis and therapeutic management of this pathology. Results: the diagnostic approach implies certain difficulties in relation to the time of presentation of the symptoms. The current tendency is to consider it as a diagnosis of exclusion, using the four phenotypes proposed in Rotterdam. The study found that changes in lifestyle, weight reduction, diet, exercise, alternative medicine, cosmetic treatments, and prevention of epigenetic factors, surgical and pharmacological therapy contribute to improve the quality of life and symptoms in affected patients with this nosological entity. Conclusion: Polycystic ovarian syndrome remains a disease with a diagnosis of exclusion, but the current trend is to investigate the anti-mullerian hormone as a predictor of this disease. The treatment aimed at correcting hyperandrogenism, menstrual disorders, associated metabolic disorders and anovulation(AU)
