Poorly cohesive carcinoma (PCC) is an uncommon neoplasm characterized by tumorous cells exhibiting a lack of adhesion. PCC has been reported rarely in the small intestine other than at the ampulla of Vater. We present a 40-year-old man with recurrent abdominal pain and small bowel obstruction.

This study was cross-sectional and included 158 clinical isolates; each isolate corresponded to a different Peruvian patient, genotyped by polymerase chain reaction to detect gene and EPIYA motifs, the gene (alleles , , , , , , , and subtypes , and ), the gene (alleles and ), and the gene (allele ). We observed that 38.

- Candida empyema is a rare but severe condition primarily affecting immunocompromised individuals, showing high mortality if not correctly managed.
- A case study reveals a patient with gastric cancer undergoing chemotherapy who developed this condition after gallbladder surgery, yet was successfully treated with fluconazole and drainage.
- The case emphasizes the importance of considering Candida in patients with cancer presenting with pleural effusion, highlighting that early detection and treatment are crucial for better outcomes.
Acute intermittent porphyria (AIP) is a rare autosomal dominant inherited disease, predominantly seen in female patients, caused by mutations in the hydroxymethylbilane synthase gene. When impaired, elevated heme biosynthesis precursor levels accumulate in the liver, resulting in neurological symptoms, psychiatric disturbances, darkened urine color, abdominal pain, nausea, vomiting, and ileus. We present a 22-year-old Hispanic female with diffuse abdominal pain and no bowel movements for 8 days.

- The study investigated how the concentration of plumericin, a bioactive metabolite from the plant Himatanthus tarapotensis, varied under different soil conditions and rainfall patterns, and its use in defending against insect herbivores.
- Results showed that plumericin levels were significantly higher in plants on clay soil compared to white-sand soil, but were not influenced by precipitation, and interactions with herbivores like Isognathus leachii were complex.
- Furthermore, the research indicated a significant connection between plumericin concentration and the abundance of Hymenoptera (ants), which was affected by soil nutrient parameters like carbon, clay, and phosphorus content.
Topical analgesics and topical rubefacients are widely used to control acute as well as chronic pain every day. Due to their availability without a prescription, consumers often overlook any potentially harmful effects and consider them largely benign. Here, we present a rare case of chemical burn triggered by a typical over-the-counter (OTC) analgesic containing menthol and methyl salicylate resulting in chemical burn, complicated by necrotizing infection treated by below the knee amputation.

- The study aimed to analyze the resistance of Helicobacter pylori to 5 reference antibiotics in 500 dyspeptic patients from two healthcare facilities in Lima, Peru.
- Researchers collected gastric biopsies from patients, isolating 273 H. pylori strains and assessing their susceptibility using a broth microdilution method.
- Results showed a significant increase in antimicrobial resistance, especially to Levofloxacin, Metronidazole, and Amoxicillin, suggesting a need for better surveillance methods in hospitals to monitor H. pylori resistance trends.

Article Synopsis
- * Results showed a 46.3% infection rate and high resistance to antibiotics: 52.3% for clarithromycin, 29.6% for metronidazole, 45.5% for levofloxacin, and 4.6% for amoxicillin.
- * A significant 43.5% of strains exhibited mutations linked to clarithromycin resistance, indicating a troubling level of antimicrobial resistance in the area.
The venom peptide bicarinalin, previously isolated from the ant , is an antimicrobial agent with a broad spectrum of activity. In this study, we investigate the potential of bicarinalin as a novel agent against , which causes several gastric diseases. First, the effects of synthetic bicarinalin have been tested against : one ATCC strain, and forty-four isolated from stomach ulcer biopsies of Peruvian patients.
