RESUMO
Pregnant women with end-stage kidney disease who undergo peritoneal dialysis have lower pregnancy rates and higher obstetric risk than their peers undergoing hemodialysis. Although there has been some improvement in pregnancy rates and outcomes due to the intensification of dialysis prescriptions, there is currently a lack of guidelines for optimizing peritoneal dialysis regimens for pregnant women with end-stage kidney disease. Besides, there is limited data available regarding pregnancy outcomes in women with end-stage kidney disease undergoing peritoneal dialysis. We report the case of a 23-year-old Hispanic woman with end-stage kidney disease caused by focal and segmental glomerulosclerosis. She became pregnant while undergoing successful treatment with an intensified automated peritoneal dialysis regimen. The patient gave birth to a live female preterm infant weighing 938 g during the 28th week of her pregnancy. The baby required neonatal intensive care due to prematurity, extremely low birth weight, and respiratory distress syndrome.
RESUMO
The genomic characteristics of Peruvian patients with gastric adenocarcinoma from diverse socioeconomic backgrounds were examined in consideration of the possibility that patients from different socioeconomic backgrounds may be exposed to different risk factors. We conducted a prospective pilot study in two Peruvian cities (Lima and Ica). This study enrolled 15 patients from low socioeconomic status (LSES) and 15 patients from medium/high socioeconomic status (MHSES). The genomic profiling of gastric adenocarcinoma samples was done through the FoundationOne CDx platform. We compared the genomic characteristics and the need for targeted therapy and immunotherapy between LSES and MHSES. The genes with higher rates of alterations were TP53 (73.3% vs. 50.0%, P = 0.2635); CDH1 (26.7% vs. 28.6%, P = 1); CDKN2A (20.0% vs. 28.6%, P = 1); KRAS (33.3% vs. 7.1%, P = 0.1686); ARID1A (20.0% vs. 14.3%, P = 1); MLL2 (13.3% vs. 21.4%, P = 1) and SOX9 (33.3% vs. 0.0%, P = 0.0421) in LSES versus HMSES, respectively. There was no significant difference in tumor mutational burden (P = 0.377) or microsatellite status (P = 1). The LSES group had a higher need for targeted therapy or immunotherapy according to gene involvement and alterations. A significant genomic difference exists among patients with gastric adenocarcinoma of different socioeconomic status, which may result in a different need for targeted therapy and immunotherapy.

Gastric cancer (GC) ranks fifth on the list of the most common malignancies worldwide. In Peru, gastric neoplasms are considered the second leading cause of mortality among males. Among the molecular subgroups of GC, microsatellite instability presents a favorable prognosis due to its hypermutated phenotype, which activates immunosurveillance. The present study describes the case of a 75-year-old patient, who was admitted in the hospital with a history of upper gastrointestinal bleeding and recurrent hospital admission, due to severe anemia. The patient presented with pale skin, normal vital functions, slight swelling of the lower extremities, and abdominal distention and bloating upon a physical examination. An endoscopic examination revealed an infiltrating circular ulcerated lesion. The histopathological analysis identified a moderately differentiated intestinal-type adenocarcinoma with pathological stage T3N0M0. Tumor genomic profiling demonstrated alterations in 15 different genes with a tumor mutational burden of 28 mutations/Mb. Finally, the patient underwent a partial gastrectomy without pre-operative chemotherapy. After 4 days, the patient presented with post-operative complications for which he was re-operated on. The patient did not survive. To the best of our knowledge, in the present case, pernicious anemia was an early sign of GC and a gastroscopy had to be performed. Furthermore, MutS homolog 3 alterations probably conditioned the presence of multiple frame-shift mutations.
RESUMO
Totally implanted central venous port systems are widely used to access central veins for patients needing long-term therapy. These devices have low rates of complications and are commonly used to administer medications like chemotherapeutic agents. Spontaneous rupture of a catheter segment is a rare mechanical complication, usually belatedly diagnosed and presenting with complications. We present a case of a spontaneously ruptured chemotherapy catheter diagnosed using a novel approach via oblique projections on chest X-rays and successfully removed using an endovascular approach.
RESUMO
Gastric cancer is one of the most important malignancies in the world due to the high burden of disease and lethality. In this work, we compared the main characteristics of gastric cancer between different regions of the world. We reviewed public repositories to retrieve epidemiological, molecular, clinicopathological, and risk factor data. Eastern Asia presents the highest incidence of gastric cancer, followed by eastern and central Europe. Intestinal histology was more frequent in Caucasians, while gastric tumors located in the cardias were less frequent in Africa and Latin America. TP53, LRP1B, and ARID1A are consistently the most frequently altered genes in all population groups. Gastric cancer is most frequent in men. African patients tend to be younger and have a higher proportion of women patients. Different patterns can be observed in the presentation of gastric cancer between different regions of the world. More research is needed in Latin America and Africa since these populations are underrepresented.

A pneumothorax is the abnormal gas accumulation within the pleural space. We present a case of a patient with an occult iatrogenic pneumothorax who presented with symptomatic anemia that substantially improved after a transfusion, diverting the clinical suspicion. As a result, she developed acute respiratory distress, initially considered secondary to a possible pulmonary embolism vs. fat embolism. After computed tomography confirmed the diagnosis, a chest tube was inserted. This case emphasizes the importance of suspecting pneumothorax secondary to cosmetic procedures and using computed tomography as the first diagnostic tool in complex cases since chest x-rays can miss pneumothorax.
RESUMO
Sepsis due to nosocomial pathogens markedly increases morbidity and mortality in the critically ill patient. The SARS-CoV-2 (COVID-19) pandemic has increased the number of patients requiring intensive care unit (ICU) in-patient management. Chryseobacterium indologenes (C. indologenes) is a group of multiresistant gram-negative bacteria associated with in-hospital environment and catheter-associated infections of increasing importance in the ICU. SARS-CoV-2 severe infection in the critically ill patient increases the risk of abdominal compartment syndrome (ACS) and acute kidney injury (AKI). We hereby report a case of a patient with SARS-CoV-2 severe infection, C. indologenes sepsis, abdominal compartment syndrome, and secondary renal failure.
