Intra-abdominal infections (IAI) occur due to disruption of the normal anatomic barrier.
In the hollow viscera is where common disruptions occur, which allows intraluminal bacteria to invade and proliferate in the usually sterile area (ie peritoneal cavity or retroperitoneum).
Community-acquired intra-abdominal infection is usually secondary to gastroduodenal perforation, ascending cholangitis, cholecystitis, appendicitis, colon diverticulitis with or without perforation, or pancreatitis.
Uncomplicated IAI infectious process involves only a single organ and does not extend to the peritoneum.
Complicated IAI is when infection extends beyond the hollow viscus of origin into the peritoneal space and may be associated with peritonitis or abscess formation.
Treatment failure in osteoporosis remains a problem, even among patients who are treatment-adherent, according to a presentation at the recent meeting of the Asian Federation of Osteoporosis Societies (AFOS 2017), held in Kuala Lumpur, Malaysia.
Bisphosphonates have proven antifracture efficacy and remain to be the cornerstone of osteoporosis treatment. However, a drug holiday is of particular importance with bisphosphonates due to some signals with long-term use of the drug, including rare incidence of atypical femoral fracture (AFF) and osteonecrosis of the jaw (ONJ), says a leading endocrinologist at AFOS 2017.
Breast cancer patients have notably different microbiomes in the local breast tissue and urinary tract, a recent study reveals. Particularly, species in the Methylobacterium genus are reduced in the local breast tissue while the urinary tract is enriched in gram-positive bacteria.
