Abdominal hernias are defects due to loss of continuity of the fasciae and/or muscles with the protrusion of abdominal structures. They are the third most prevalent and incident abdominal pathology worldwide and the second pathology of consultation in general surgery in patients of age limits. There are various factors that contribute to their formation, but within the scientific community there are various types of classifications, which differ according to the professional training school and their decision-making. This bibliographic review aims to expose the most used abdominal hernia classification systems such as the European one that has a morphological vision, the Ventral Hernia Working Group that proposes its aspect on recurrence together with the modified one that exposes comorbidity and the staging system of ventral hernia that provides a comprehensive approach to classification and management. In addition to the most common complications of the same.

Thyroid pathology is the morphofunctional evolution of the thyroid glands that leads to different types of clinical pictures. Within it is subclinical hypothyroidism, which is a biochemical alteration due to the elevation of thyroid-stimulating hormone (TSH) between 4.5 to 10 mUI that can occur with or without symptoms of multifactorial origin. The worldwide prevalence is 4-10% and Latin America 15-25%. 90% of patients with this pathology do not require treatment, but in turn there is an overmedicalization and underdiagnosis of it. This bibliographic review analyzes from its morphofunctional changes towards clinical criteria for a comprehensive approach to subclinical hypothyroidism, where we have an individualization by its comorbidities, age group, diagnostic algorithm, follow-up and differentiated treatment according to recent studies within this pathology. Therefore, an adequate diagnosis, follow-up and treatment provides a better lifestyle for patients.

Introduction: The oral cavity is continuously exposed to inhaled and ingested carcinogens (mainly tobacco and alcohol), and therefore it is the most common site for the origin of neoplasms in the head and neck region. Methods: A descriptive, retrospective, observational study of non-probabilistic sampling of consecutive cases was carried out. Adult patients with a clinical and pathological diagnosis of oral cavity cancer were included. Results: A series of 17 cases of oral squamous cell carcinoma was included, 13 men (76%) and 4 women (24%). The age of the individuals ranged between 32 and 73 years. 65% of the patients were smokers, and 71% reported consumption of alcoholic beverages. The tongue was the most frequent tumor location, 71% were in stage IV, and with a moderate degree of histological differentiation. Conclusion: Most of the patients in this study were males between 50 and 70 years of age. A high percentage of patients reported smoking, and an even higher percentage of alcohol consumption. The most frequently affected subsite is the tongue, in advanced stages and a moderate degree of differentiation.

Coanal polyp is the term used for a solitary, benign soft tissue mass extending into the junction of the nasal cavity and nasopharynx, i.e., the choana. Nasal coanal polyps typically present in three different forms: antrochoanal, sphenocoanal, and ethmoidocoanal polyps. Atypical sites of origin have been reported in the literature; these include the nasal septum and inferior turbinate. Physicians’ awareness of the existence of coanal polyps from unusual sites may help in the diagnosis of coanal polyps considering it crucial to previously rule out other potential diagnoses for these cases of atypical presentation. Here we report the case of an inflammatory polyp of insertion in the roof of the nostril in a 65-year-old patient diagnosed and treated in our department, which is the first case reported in the literature.

The primary function of the circle of Willis is to provide collateral blood flow between the anterior and posterior arterial systems of the brain. Its configuration can vary considering its vascular structures, this being considered an anatomical variant. Our study aims to determine the prevalence of these, discriminated by sex in corpses subjected to medicolegal autopsy at the National Institute of Legal Medicine and Forensic Sciences in 2019, in Cali-Colombia. Retrospective observational descriptive study, of photographic records, inspection records and expert reports, where variables of age, sex, anatomical variants, compromised vascular structures are differentiated. Univariate and bivariate analyzes were performed. The population consisted of 194 cases, with a median age of 33 years (interquartile range between 23-45). 24.4% corresponded to the male sex. A prevalence of 25.3% of cases with non-classic polygon was observed. The most frequent anatomical variant was hypoplasia 14.9%. The vascular structure that presented the most anatomical variants was the posterior communicating artery with 17%.

Anaplastic meningioma represents less than 5% of all meningiomas. It is a neoplasm with a poor prognosis due to aggressiveness and a high rate of recurrence. Patients could remain asymptomatic but clinical characteristics of mass effect are the most common presentation. Although diagnosis is made with histological study, this method is difficult to define, with inter-observer variability. When possible, surgical resection is the primary management. We discuss a case of an adult female patient with tonic-clonic seizures and weakness attributed to an anaplastic meningioma in the occipital lobe. The patient was treated with a parietal craniotomy with complete resection.  One month later the patient suffered a recurrence of the tumor with the need for further intervention with incomplete resection. Due to extent of the damage the patient deceased two weeks later.

Depression is considered the most frequent mental illness; it is a cause of disability and constitutes a modifiable risk factor for the future development of dementia. The objective of tis study was to determine the frequency of major depression in elderly aged 85 and over and its possible association with dementia and with sociodemographic and clinical aspects. A descriptive cross-sectional study was carried out in 202 elderly who were treated in the protocolized consultation ¨The care of cognitive disorders in the elderly ¨, of the Hermanos Ameijeiras hospital, during the period between February 2016 and May 2016. 2020. 55.9% of the elderly were women and 64.9% were between 85 and 89 years old. A significant association was found between major depression and having comorbidity (p = 0.001), being a smoker (p = 0.003) and being a drinker (p <0.001). Major depression and dementia were diagnosed in 12.9% of the elderly, with no significant relationship (p = 0.731). The frequency of major depression in elderly aged 85 and over who were treated in a care consultation for cognitive disorders in the elderly is considered high. An association was identified between factors that deteriorated health and the presence of major depression, but not between it and dementia.

Congenital Interatrial Septal Defects (TEA) are among the most common Congenital Heart Diseases in the population, where Atrial Septal Defect stands out, which is produced by a left-right short circuit that provides greater survival and less morbidity and mortality. The objective was to determine the results of Percutaneous Closure with a Device in Congenital Heart Disease of the Atrial Communication type at the Carlos Andrade Marín Specialty Hospital (Quito) in the Hemodynamics service from January 2009 to July 2019. It is a retrospective descriptive cross-sectional study . With a population of 122 cases from the AS400 registry. Thus, it was determined: there is a female predominance in a ratio of 2:1, the ranges for defect intervention were 5.5 mm to 35 mm, post-procedure pulmonary artery pressures (systolic 18-25 mmHg and diastolic 6-10 mmHg) in 95% of patients, ventricular overload in 76% in pre-procedure patients. Concluding that 96% of our population has a significant post-procedure improvement

The pituitary adenomas comprise the largest part of pituitary neoplasms, representing between 9 and 12% of primary brain tumors. Currently, the treatment of election is the surgical, the trans-sphenoidal endonasal path has provided a broader panoramic view, being feasible more delicate and safe procedures. The objective of this study was to describe the management of pituitary adenomas by endoscopic surgery trans-sphenoidal endonasal path. This is a study in a series of cases, with a sample of 17 patients who met the selection criteria and were attended at the José Carrasco Hospital Arteaga, Cuenca - Ecuador, period 2018 - 2019. All patients presented informed consent for the performance of the surgery and the subsequent dissemination of the results. The 53% of the population belonged to the male gender, 47% were patients between 40 and 60 years old, 65% were detected with macroadenomas, and 29% presented complications such as nasal obstruction, sphenoiditis and headache, the residual tumor stage was due 24%.Endoscopic surgery trans-sphenoidal endonasal path is a safe, minimally invasive tool, a surgical alternative with a high rate of tumor excision, better control and fewer complications, which reduces the morbidity of patients.

Spinal Paragangliomas are rare tumors, most frequently involving the cauda equina and the filum terminale. We report the case of a 62-year old woman presenting with a one month’s lower back pain, left sciatica and leg weakness. Spinal magnetic resonance imaging showed a extramedullary lesion at L3-L4 level, measuring 37 x 52 x 21   mm with contrast enhancement. It presented an unenhancing intradural cystic lesion in the upper pole. The patient underwent lumbar laminectomy, and with neurofisiologic monitorization the tumor was completely resected. Microscopic examination of the tumor revealed a paraganglioma. In a review of the literature, we found only five previous reported cases in which the tumor is accompanied by a cyst.
