Doxycycline is a broad-spectrum antibiotic belonging to the tetracycline group which acts by inhibiting bacterial protein synthesis. It is considered to be a relatively safe drug. We report a case of doxycycline-induced acute pancreatitis (DIAP) in an adult female patient who was started on the usual therapeutic dose 1 week before for acne vulgaris. The WHO causality assessment was possible, and the Naranjo scale confirmed it as "definite" adverse drug reaction. A brief literature review on case reports previously reporting DIAP has also been summarized...

Growing evidence suggests that microbes can influence the efficacy of cancer therapies. By studying colon cancer models, we found that bacteria can metabolize the chemotherapeutic drug gemcitabine (2',2'-difluorodeoxycytidine) into its inactive form, 2',2'-difluorodeoxyuridine. Metabolism was dependent on the expression of a long isoform of the bacterial enzyme cytidine deaminase (CDDL), seen primarily in Gammaproteobacteria. In a colon cancer mouse model, gemcitabine resistance was induced by intratumor Gammaproteobacteria, dependent on bacterial CDDL expression, and abrogated by cotreatment with the antibiotic ciprofloxacin...

BACKGROUND: CFTR2 provides clinical and functional information of the most common CFTR-mutations. Rare mutations (RMs) occur in only a few patients with limited reported clinical data. Their role in CF-disease liability is hardly documented. METHODS: Belgian CF-Registry 2013 data were analyzed to identify CF with at least 1 RM (CF+RM). Clinical data and sweat chloride of CF+RM were compared to CF-controls, carrying 2 class 1 to 3 mutations (CFclassic). Disease severity was compared between both groups...

We report a case of a 56-year-old woman who presented with worsening abdominal pain located in the left upper quadrant together with abdominal distention, nausea and anorexia. One month prior to this admission, she had presented and had been diagnosed with concurrent acute pancreatitis and rapidly expanding abdominal aortic aneurysm. The aneurysm was prioritised over the pancreatitis and she underwent uncomplicated endovascular repair. Cross-sectional imaging was consistent with infected pancreatic necrosis and also revealed a large collection located in the anterior pararenal space with extensive gas formation...

Cystic fibrosis (CF) is a disease caused by a mutation in the cystic fibrosis transmembrane conductance regulator protein in the epithelial membrane, and affects at least 30,000 people in the USA. There are between 900 and 1000 new cases diagnosed every year. Traditionally, CF has been treated symptomatically with pancreatic enzymes, bronchodilators, hypertonic saline, and pulmozyme. In July 2015, the US Food and Drug Administration approved Orkambi (lumacaftor/ivacaftor), a combination drug that works on reversing the effects of the defective cystic fibrosis transmembrane conductance regulator protein...

Thad Wilkins, Jacqueline Sequoia
Probiotics contain microorganisms, most of which are bacteria similar to the beneficial bacteria that occur naturally in the human gut. Probiotics have been widely studied in a variety of gastrointestinal diseases. The most-studied species include Lactobacillus, Bifidobacterium, and Saccharomyces. However, a lack of clear guidelines on when to use probiotics and the most effective probiotic for different gastrointestinal conditions may be confusing for family physicians and their patients. Probiotics have an important role in the maintenance of immunologic equilibrium in the gastrointestinal tract through the direct interaction with immune cells...

INTRODUCTION: There are new concepts and developments in the diagnosis and management of acute pancreatitis. Current evidence suggests that there is no role of prophylactic antibiotics use in acute pancreatitis. However, it is still a common practice to administer prophylactic antibiotics in a country like Nepal. So, we have conducted a study in mild and moderately severe acute pancreatitis to study the efficacy of prophylactic antibiotics. METHODS: A case control study was conducted among 76 patients comparing efficacy of prophylactic antibiotics versus no antibiotics in patients with mild and moderately severe acute pancreatitis...

RATIONALE: Drug-induced pancreatitis (DIP) is a rare type of pancreatitis that is not usually observed in the clinical practice. It is generally difficult to distinguish from acute pancreatitis (AP) induced by other causes. PATIENT CONCERNS: Here, we report a 62-year-old Chinese female patient with "small cell lung cancer" as the initial presentation. Because the patient could not bear the surgical treatment, the chemotherapy composed of lobaplatin and etoposide was performed...
