Case report: Uncommon gastric metastasis as a presentation of recurrent clear cell renal cell carcinoma.

Renal cell carcinoma (RCC) is a kidney neoplasm that accounts for 85% of cases and has complex genetic pathways that affect its development and progression. RCC metastasis can occur in 20%-50% of patients and usually affects distant organs. Gastric metastases (GM) from RCC are rare and present as polyp-like growths in the submucosal layer, accounting for 0.2%-0.7% of cases. This case report describes an 84-year-old female with Furhman grade II ccRCC who presented with an atherothrombotic ischemic stroke and gastrointestinal bleeding nine years post-radical nephrectomy. Gastroscopy revealed a 12mm pseudopedicled gastric lesion with ulceration and bleeding, diagnosed as metastatic ccRCC. The discussion focuses on the rarity, diagnostic challenges, and prognostic elements of gastric metastasis from RCC. The median survival after detecting digestive metastasis varies widely, and the mechanisms include direct invasion and dissemination through lymphatic, transcelomic, or hematogenous routes. Prognostic markers encompass patient history, symptoms, time since RCC diagnosis, overall health, and genetic factors. Surgical removal of gastric lesions and targeted therapy are treatment options that can improve survival. This case report highlights the need for further research to enhance diagnostic and treatment strategies for this rare aspect of RCC pathophysiology.

Paraneoplastic dermatomyositis associated with urothelial cancer: report of a case and systematic review of the literature.

Background: The idiopathic inflammatory myopathies (IIM) are a collection of autoimmune diseases that have a substantial impact on the entire body and include conditions such as dermatomyositis (DM), polymyositis (PM), sporadic inclusion body myositis, and immune-mediated necrotizing myopathy. These disorders are characterized by symptoms such as muscular weakness, pain, and dermal rash. This systematic review is intended to explore the potential link between bladder cancer and DM/PM. Methods: We performed a comprehensive systematic search on PubMed and Scopus until August 2022 to identify relevant research studies. The studies that met our inclusion criteria focused on patients with urinary bladder cancer and dermatomyositis, and/or polymyositis. Results: The patients' median age was 65.5 years (47-79), with the majority being male (15, 39.47%). Bladder cancer manifested before PM/DM in 5 (13.15%) patients, while in the majority of cases occurred after the cancer diagnosis. The stage of cancer at the time of the initial PM/DM diagnosis were mostly locally (11/20, 50%).During the first presentation, the patients had a median creatine kinase level of 2227 U/L, ranging between 44 and 10471. In one case, anti-TIF-1γ antibodies were found to be present. Among the cases with reported medical history (20/38), treatment immediately improved DM symptoms in 16 patients(53.8%) and in 3 patients(15%), symptoms of DM resurfaced during the period after the operation. Death was reported in 14 (36.8%) patients. Conclusion: In conclusion, our study provides knowledge and understanding for identifying specific risk factors in patients with the coexistence of bladder cancer and DM/PM and their management. During the initial and follow-up screening, age, gender, and the clinicopathological subgroup of myositis should be considered to ensure proper management of the condition.

Case Report: A Presentation of Early-Onset Immune-Mediated Bullous Pemphigoid in a Patient with Urothelial Cancer.

Cutaneous immune-related adverse events (cirAEs) are the most common side effects of immune checkpoint inhibitor (ICI) therapy (30-50% for all grades). The vast majority of them are low or mild and can be treated without ICI interruption. Autoimmune blistering disorders, such as immune-mediated bullous pemphigoid (IBP), are rare (<1%) but potentially serious conditions that must be early detected. The onset generally occurs within the first months of the treatment, and it appears to be more common with antiprogrammed death-1 or antiprogrammed ligand 1 (anti-PD1/PDL1) than with anticytotoxic T-lymphocyte-associated protein 4 (anti-CTLA4). We present a case of a three-day severe IBP onset after receiving the first cycle of atezolizumab. This exceptional early presentation could suggest the presence of some predisposing condition and demonstrates the need to better understand predictive toxicity-related biomarkers in candidate patients for immunotherapy.

Flecainide intoxication in pediatric patients with supraventricular tachycardia.

Flecainide is a class IC antiarrhythmic indicated for ventricular and supraventricular arrhythmias in pediatric patients without structural heart disease. Flecainide has a narrow therapeutic window and proarrhythmic effect even in therapeutic doses and could lead to a life-threatening intoxication. Dosage errors, accidental intakes, and drug or food interactions, especially with dairy products, can be the cause of the intoxication. We report three consecutive cases of flecainide intoxication in children with supraventricular tachycardia (SVT) in our hospital from 2017 to 2019. Two cases had complete and spontaneous normalization of electrocardiogram (ECG) after flecainide removal. However, admission to the intensive care was required due to a sustained ventricular tachycardia in one case. Flecainide intoxication can be a life-threatening complication in patients with SVT. We believe all children should have close monitoring with serial ECG and plasma levels of flecainide during the 48-72 h after initiation of treatment, and consider hospitalization for patients <1 year of age.

Cost-effectiveness of a Barcelona home care program for individuals with multimorbidity.

To improve the efficiency and effectiveness of care and optimize healthcare resources, a home healthcare program was created for individuals with multiple chronic conditions. Demographic and clinical characteristics of the 261 individuals (mean age 84) included in the program from its inception in 2011 through 2013 (mean stay in the program 203±192 days) were prospectively analyzed. The number of hospital admissions, length of stay, and costs for individuals admitted to the program were compared for two time periods: the 6 months before admission to the program and their stay in the program. After admission to the program, the number of hospital admissions and the hospital length of stay per person per month decreased from 0.36±0.21 to 0.19±0.52 (P<.001) and from 3.5 to 1 day (P<.001), respectively. Surveys of randomly selected patients and caregivers showed high satisfaction with the program. Costs per person per day decreased from €54.65 (US$73.12) to €17.91 (US$23.96), a reduction of 67.1%. Fewer admissions and shorter hospital stays enabled the hospital to eliminate one acute bed for every 50 individuals admitted to the program. In conclusion, home care for individuals with chronic illness with multimorbidity reduced the number of hospital admissions and length of stay, resulting in good patient satisfaction and lower costs.

Chlorhexidine-methanol burns in two extreme preterm newborns.

Safe and effective antiseptic use in neonatal intensive care units is mandatory. High efficacy and a low number of side-effects from chlorhexidine have permitted avoidance of the use of mercurials and iodine derivatives, but methanol use can be unsafe in extreme preterm newborns. We report two cases of chemical burn after skin cleansing, due to alcoholic chlorhexidine (0.5%) use in extremely premature infants used for umbilical catheter insertion. Although this formulation is less concerning for use in full-term newborns, nonalcoholic preparations are preferable for use in preterm newborns.

Energy intake, metabolic balance and growth in preterm infants fed formulas with different nonprotein energy supplements.

OBJECTIVE: To study metabolic and energy balances, growth and composition of increased body mass in healthy preterm infants fed control formula or control formula with three different nonprotein energy supplements. PATIENTS AND METHODS: Growing preterm infants (birth weight < 1,500 g and gestational age < 31 weeks) were fed standard preterm formula (control group) or the same formula enriched with three different nonprotein energy supplements. An energy supplement of 23 kcal/kg/day was achieved by adding medium-chain triglyceride and dextrinomaltose in three different caloric ratios: 33:66 in group A, 66:33 in group B, and 85:15 in group C. Energy balance was determined by open-circuit continuous (5-6 hours) measurements of energy expenditure, with simultaneous measurement of 24-hour urinary nitrogen excretion. Metabolic balance was determined by measurements of energy intake, energy oxidation, and energy output in urine and stool. The composition of body mass accretion was determined as the accretion of fat and protein in the total weight gain. RESULTS: The fat accretion (4.9, 5.9, 6.2, and 3.8 g/kg/day in groups A, B, C and D, respectively) correlated directly with fat intake. Infants receiving standard energy intake had a fat percentage of weight gain significantly lower (28%) than that of the high-energy intake groups (31%, 40%, and 38% in groups A, B, and C, respectively). This difference corresponded to the results obtained from skinfold thickness measurements. CONCLUSIONS: Excess nonprotein energy is stored as fat regardless of its source (fat or carbohydrate). High caloric and medium-chain triglyceride intake in otherwise healthy growing preterm infants does not promote nitrogen retention.
