Introduction: Polycystic ovary syndrome (PCOS) is a common endocrine disorder, affecting up to 18% of women of reproductive age and up to 70% remains undiagnosed, depending on the population and the diagnostic criteria used. PCOS is characterized by oligo/anovulation, hyperandrogenism, and polycystic ovaries. Objective: To provide an overview of current information on PCOS and cardiometabolic risk factors. Methodology:  A literature review was conducted based on the search for scientific publications related to the subject. Results: women with PCOS are at increased risk of cardiometabolic disorders such as overweight, obesity, high body mass index, insulin resistance, glucose intolerance, diabetes mellitus 2, dyslipidemia, hypertension, cardiovascular disease, and metabolic syndrome. Conclusions: The presence of cardiometabolic risk factors in women with PCOS increases the baseline risk of suffering from cardiometabolic disease, one of the main causes of death in women, therefore, prevention, diagnosis and timely and adequate treatment is essential starting from the first level of health.

Introduction: The use of a personal mask by health personnel and the general population is necessary during the COVID-19 pandemic, however, it has resulted in a significant increase in the prevalence of allergic contact dermatitis, irritant contact dermatitis, dermatitis seborrheic, contact urticaria and exacerbation of acne and skin infections. Methodology: non-systematic review on allergic contact dermatitis associated with the use of masks and N95 respirators during the COVID 19 pandemic, the terms, and descriptors "dermatitis and mask" and "dermatitis and Covid-19" were used in the databases. ScienDirect, PubMed, SciELO and Redalyc; Works published in Spanish and/or English, valid for no more than 5 years, were considered. Results: The use of the mask for a period of more than 6 hours has been shown to increase the incidence of allergic dermatitis, presenting lesions on the cheeks, dorsum of the nose, forehead and retroauricular area. Conclusions: This is a pathological entity of high incidence and underdiagnosis. It constitutes a form of type IV hypersensitivity, which if not treated in time can lead to complications associated with superinfection; Health personnel and the community in general must be educated in measures to prevent this type of injury and guide them to seek timely medical attention if necessary.

Introduction: Diabetes mellitus has a variety of complications, including diabetic gastroparesis as the most common of them, affecting morbidity, mortality, and quality of life of patients. Objective: To conduct a narrative review that describes the pathophysiology, clinical manifestations, diagnosis, and treatment of diabetic gastroparesis. Method: A non-systematic bibliographic search was conducted in the Scielo and Pubmed databases, selecting sources in Spanish or English that are relevant to the objective of this study. Conclusion: Diabetic gastroparesis is a frequent complication of diabetes mellitus, with a multifactorial origin, and a diagnosis based on gastric emptying scintigraphy. Its treatment is based on diet, maintaining euglycemia and symptomatic management.

Introduction: Keratoconus has a prevalence of 54.5 per 100,000 people, this figure varies by geographic location. Keratoconus is a corneal alteration that produces significant distortions in vision. There are no data on the presence of this disease at a local level, nor are there studies that indicate the population characteristics of the people who suffer from it. Objectives: To determine the characteristics of patients with keratoconus at the Dr. Emigdio Navia Ophthalmologic Center in the Portoviejo´s city. Methodology: Descriptive-retrospective study, using as an instrument the collection of data in corneal topographies and clinical histories of patients treated at the center. Results: A population of 4527 patients was analyzed during 2018 and 2019. In 2018, only 5 patients with a keratoconus´ diagnosis were identified, 4 were male and 1 female, between 10-75 years old; in 2019, 7 patients showed a keratoconus´ diagnosis, 5 male and 2 female, between 5-39 years old. Patients with a diagnosis of keratoconus, showed one of the most common pathologies´s symptoms referred, blurred vision. In 2018, the keratometric K values are very close to each other (CV<10) for all patients, indicating that mostly these patients have approximately the same disease progression. While, in 2019, these values show a CV>10%, which allows suggesting that keratoconus come from different sources and possess different stages. Conclusions: According to the literature, the degree of keratoconus in patients diagnosed in 2018 correspond to stages 1, 2 and 3, while, in 2019, according to keratometric data, patients with keratoconus up to stage 4 are observed.
