Colon rectal cancer (CRC) during pregnancy is a rare neoplasia, with an incidence between 0.07-0.1% in the population. For an early diagnosis, a high suspicion is necessary and with it, timely diagnostic tests are carried out. When there is no suspicion and no diagnosis is sought, the prognosis is usually poor since it is often in an advanced state. We present the cases of two pregnant women aged 27 and 31 diagnosed with moderately differentiated colorectal adenocarcinoma at 29 and 30 weeks of gestation, respectively. Due to the importance of making an opportune diagnosis to improve the survival of the patients, a search of information was carried out in the literature in relation to the diagnosis, management and prognosis of this pathology.

Vitamin D is a hormone known for a long time, for its effects on bone health and the regulation of phosphorus and calcium metabolism. Since the discovery of receptors for this molecule in a large number of cells in the body, the field has been opened for the study of its effects on the immune system. Its relationships with the cells of the immune system, genes, and microbiota cause great interest in relation to immune-mediated diseases. Many data indicates that this vitamin has preventive, modulating and controlling effects of the adverse effects of Inflammatory Bowel Diseases (IBD) on bone health, although it is difficult to definitively demonstrate causality. In this review, we try to summarize the current situation and controversial issues in this interesting field, focusing on inflammatory bowel diseases.

Gastric cancer is a multifactorial disease with important genetic and environmental factors. It is the fifth most common cancer in incidence, and the fourth cause of death secondary to cancer. The incidence of early-onset gastric cancer is increasing worldwide, but clinical information on these patients has not been well established. We analyzed the association between age and clinical, endoscopic, and histopathological characteristics of gastric cancer at the time of diagnosis in a Latin American population. A retrospective and descriptive cross-sectional study was carried out using the database of the Gastroenterology Service of the Clínica Foscal and Clínica Foscal Internacional in Bucaramanga, Colombia. Between January 2016 and December 2019, 259 de novo gastric cancer cases were diagnosed, of which 36 patients (13.9%) were 40 years old or younger. In patients with early-onset gastric, the prevalence of gastric cancer diagnosis was lower in men. A family history of gastric cancer or any other neoplasm was not associated with a higher prevalence of gastric neoplasms. In young patients, vomiting and ascites were more common, the preferred anatomical location was the body of the stomach, and the Borrmann IV classification and the diffuse-type histology were more likely. Our study showed an approximation of the characteristics of early-onset gastric cancer in a Latin American population, where we observed that early-onset gastric cancer has different demographic, anatomical, and histological features than late-onset gastric cancer.

Gastroesophageal reflux disease (GERD) is a clinical condition in which gastric reflux causes symptoms or damage to the esophageal mucosa. It is managed with proton pump inhibitors, however, up to 45% of patients with suspected GERD are refractory to treatment. It is necessary to establish a true GERD diagnosis by means of a digestive endoscopy, which does not show lesions in approximately 70% of patients. In this scenario, it is necessary to perform an esophageal pH-impedance measurement, a procedure that allows to determine whether exposure to gastric acid is pathological. Of this group, patients with pathological acid exposure are diagnosed as true non-erosive reflux disease (NERD). If, in addition to not presenting esophageal lesions, they have a physiological exposure to gastric acid, they suffer from esophageal hypersensitivity or functional heartburn, which are functional disorders. These require a different approach from that of GERD or NERD, as the symptoms are not due to pathological exposure to gastric acid. The aim was to calculate the frequency of esophageal hypersensitivity and functional heartburn in patients with suspected NERD. This was a cross-sectional study. Data was collected by reviewing pH-impedance and manometry reports, 166 patients were selected. The frequency for functional disorders was 86.15%, being 46.9% for functional heartburn and 39.2% for esophageal hypersensitivity. The frequency of functional disorders was higher than that reported in previous studies. In conclusion, age, psychological conditions, dietary, cultural, ethnic or lifestyle factors inherent to our environment might play important roles in the development of functional disorders.
