Salmonella infection predominantly causes four clinical syndromes: enteric fever, gastroenteritis, bacteremia, and asymptomatic carrier state. Salmonella osteomyelitis is an extremely rare manifestation of salmonella infection except in children with hemoglobinopathies. Salmonella osteomyelitis has been reported to mostly affect the diaphysis of long bones and lumbar spine. Here, we describe a case of salmonella osteomyelitis of the right 6th rib in a 74-year-old woman who presented with breast pain, swelling, high fever and local heat. Her medical history showed myocardial infarction; namely, at the age of 71, the patient had undergone the drug-eluting stent placement in the left anterior descending artery. A computed tomography (CT) scan at the first visit to another hospital showed a mass in the chest that invaded the ribs. 18F-fluorodeoxyglucose-positron emission tomography-computed tomography imaging showed a lesion suspected to be a mammary malignant tumor. A needle biopsy revealed mesenchymal cells and suspected mammary sarcoma. However, the osteomyelitis of the rib was diagnosed when pyogenic tissue was observed during an open biopsy. The bacterial culture examination identified Salmonella enterica. Surgical drainage and antibiotic treatment were performed. Importantly, there was no evidence for any underlying disease that could lead to an immunocompromised status of the patient. To our knowledge, this is the first report of salmonella osteomyelitis of the rib presenting in an older female that required differentiation from a mammary tumor. Clinicians should consider rib osteomyelitis when they find swelling and local heat in the female's breast tissue and detect no cancerous tissue.

Human breast milk (HBM) is an irreplaceable source of nutrition for early infant growth and development. Breast-fed children are known to have a low prevalence and reduced risk of various diseases, such as necrotizing enterocolitis, gastroenteritis, acute lymphocytic leukemia, and acute myeloid leukemia. In recent years, HBM has been found to contain a microbiome, extracellular vesicles or exosomes, and microRNAs, as well as nutritional components and non-nutritional proteins, including immunoregulatory proteins, hormones, and growth factors. Especially, the milk-derived exosomes exert various physiological and therapeutic function in cell proliferation, inflammation, immunomodulation, and cancer, which are mainly attributed to their cargo molecules such as proteins and microRNAs. The exosomal miRNAs are protected from enzymatic digestion and acidic conditions, and play a critical role in immune regulation and cancer. In addition, the milk-derived exosomes are developed as drug carriers for delivering small molecules and siRNA to tumor sites. In this review, we examined the various components of HBM and their therapeutic potential, in particular of exosomes and microRNAs, towards cancer.

BACKGROUND After initial infection with HIV, loss of CD4+ T cells progresses along a predictable timeline. The clinical latency stage lasts an average of 10 years, until the CD4+ T cell count falls below 200 cells/uL or the patient develops an AIDS-defining opportunistic infection/cancer. This report describes an unusual opportunistic infection in a young patient with no prior clinical evidence of HIV infection. CASE REPORT An 18-year-old man presented with fever, abdominal pain, and dyspnea for the previous 2 weeks and was symptomatically treated for gastroenteritis. He presented 2 weeks later with extreme fatigue, and a CT scan revealed diffuse lymphadenopathy. He was transferred to a regional hospital, but upon arrival and prior to detailed investigative work-up, he developed cardiac arrest. Despite maximal resuscitative efforts, he died approximately 8 h after admission. At autopsy, diffuse lymphadenopathy, splenomegaly, and pulmonary congestion were noted. Disseminated cryptococcal infection involving almost every organ system was identified at autopsy. A postmortem HIV-1 antibody test was positive. The cause of death was severe immunodeficiency as a result of advanced HIV infection resulting in disseminated cryptococcal infection, with cerebral edema, herniation, and respiratory failure. CONCLUSIONS This patient's non-specific symptoms in conjunction with his rapid decline made arriving at a correct diagnosis challenging. Only during autopsy was the disseminated fungal infection discovered, leading to suspicion of HIV infection. HIV autopsies are not uncommon, but the clinical history is usually known beforehand. This case report highlights the importance of considering HIV-related conditions in patients presenting with this array of symptoms, as well as to alert healthcare providers and staff to the need for increased biosafety precautions.

Dysbiosis, an imbalance of intestinal flora, can cause serious conditions such as obesity, cancer, and psychoneurological disorders. One cause of dysbiosis is inflammation. Ulcerative enteritis is a side effect of non-steroidal anti-inflammatory drugs (NSAIDs). To counteract this side effect, we proposed the concurrent use of histamine H2 receptor antagonists (H2RA), and we examined the effect on the intestinal flora. We generated a murine model of NSAID-induced intestinal mucosal injury, and we administered oral H2RA to the mice. We collected stool samples, compared the composition of intestinal flora using terminal restriction fragment length polymorphism, and performed organic acid analysis using high-performance liquid chromatography. The intestinal flora analysis revealed that NSAID [indomethacin (IDM)] administration increased Erysipelotrichaceae and decreased Clostridiales but that both had improved with the concurrent administration of H2RA. Fecal levels of acetic, propionic, and n-butyric acids increased with IDM administration and decreased with the concurrent administration of H2RA. Although in NSAID-induced gastroenteritis the proportion of intestinal microorganisms changes, leading to the deterioration of the intestinal environment, concurrent administration of H2RA can normalize the intestinal flora.
