INTRODUCTION: Rotavirus is a leading cause of acute gastroenteritis and mortality among children worldwide but data describing rotavirus disease in Azerbaijan are lacking. This analysis describes the rotavirus disease burden in Baku, the largest city in Azerbaijan. METHODS: We conducted active, prospective, sentinel hospital surveillance with laboratory confirmation for rotavirus among children under 5 years of age hospitalized at a large pediatric hospital in Baku during 2011-2016...

Although it has been recognized that intestinal bacteria play an important role in the pathology of human ulcerative colitis (UC), specific pathogenic bacteria for UC have not been identified. We investigated the influence of Paraclostridium bifermentans PAGU1678 strain on the pathology of a UC mouse model and found it increased UC pathosis scores such as loose and bloody stools, reduced diversity of fecal flora, disappearance of the crypt structure of distal colon tissue, destruction of intestinal epithelial cells, and atrophy of the colon...

A 15-year-old adolescent boy presented with chronic constipation, difficulty in defecation, and episodic bloody stools. A rectal mass lesion was digitally palpated. Colonoscopy showed a large circumferential polypoid lesion of the mid-rectum. Snare polypectomy was performed, and histopathology confirmed a diagnosis of benign inflammatory cap polyposis. At 3-month follow-up, sigmoidoscopy showed multiple recurrences of polyps at the site of the previous rectal polypectomy, which were removed by combined hot snare polypectomy and argon plasma coagulation...

BACKGROUND: The 2016 CHEST consensus guidelines recommend use of either 21- or 22-G needles for endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). We decided to prospectively compare sample adequacy and diagnostic yield of the 19-G with the 22-G EBUS needle, hypothesizing that a larger gauge difference might magnify the differences between 2 needle sizes. METHODS: Twenty-seven patients undergoing EBUS-TBNA at our institution were evaluated...

The care of 40 patients with primary liver cancer with obstructive jaundice treated with liver puncture bile drainage or biliary stent implantation was reported. Treated with the interventional therapy, patients were observed closely to identify symptoms of hepatic encephalopathy and pain; diet care was well performed. Bile drainage tube and skin acre were performed carefully. Liver function, bilirubin and other biochemical indicators were monitored; occurrence of bleeding, acute pancreatitis, biliary tract infection, leakage of ascites around drainage tube and other complication were observed with good discharge instruction...

Shiga toxin-producing Escherichia coli (STEC) cause bloody diarrhea (BD), hemorrhagic colitis (HC), and even hemolytic uremic syndrome (HUS). In Nordic countries, STEC are widely spread and usually associated with gastrointestinal symptoms and HUS. The objective of this study was to investigate the occurrence of STEC in Swedish patients over 10 years of age from 2003 through 2015, and to analyze the correlation of critical STEC virulence factors with clinical symptoms and duration of stx shedding. Diarrheal stool samples were screened for presence of stx by real-time PCR...

Pyoderma gangrenosum is a rare ulcerative condition associated with various systemic diseases. Lesions on the lower extremities and the trunk are common, but lesions on the nose are rare. Here we report a case of pyoderma gangrenosum on the nose. A 33-year-old woman presented with fever, nasal obstruction, and painful swelling on the nasal bridge. Physical examination revealed swellings on the nasal septal mucosa bilaterally. Computed tomography showed a septal abscess and a subcutaneous abscess on the nasal bridge...

New Zealand has a relatively high incidence of human cases of Shiga toxin-producing Escherichia coli (STEC), with 8.9 STEC cases per 100,000 people reported in 2016. Previous research showed living near cattle and contact with cattle feces as significant risk factors for STEC infections in humans in New Zealand, but infection was not linked to food-associated factors. During the 2014 spring calving season, a random stratified cross-sectional study of dairy farms (n=102) in six regions across New Zealand assessed the prevalence of the 'Top 7' STEC (serogroups O157, O26, O45, O103, O111, O121, O145) in young calves (n=1,508) using a culture-independent diagnostic test (PCR/MALDI-TOF)...

Repeated cycles of dextran sulfate sodium (DSS) administration in mice, inducing chronic relapsing colitis, have been used to mimic human ulcerative colitis (UC). However, no systematic characterization of pro-inflammatory cytokines in these DSS mice has been reported. In this study, the development of colitis was examined by assessment of the disease severity and inflammation in the colon of C57BL/6 mice that received DSS. ELISA was used to analyze the levels of pro-inflammatory cytokines in serum, colon, spleen and supernatant of cultured splenocytes...

Patients with inflammatory bowel disease (IBD) have been reported to have an increased risk of thromboembolism. Cerebral venous thrombosis (CVT) is a rare but serious extraintestinal manifestation of IBD. Due to its highly variable manifestation and low incidence, CVT is not usually readily recognized by physicians. Herein, we report a case of a 35-year-old male presenting with CVT associated with ulcerative colitis (UC). The patient was admitted with chief complaints of bloody diarrhea that had started 3 days prior...

INTRODUCTION: Fecal microbiota transplantation (FMT) is currently being explored as a potential therapy for ulcerative colitis (UC). Here, we report the first case of a UC patient with allergy to 5-aminosalicylic acid (5-ASA) who underwent FMT and achieved clinical remission. CASE PRESENTATION: This patient had a 9-year history of UC and was allergic to 5-ASA. He suffered from gradually aggravated abdominal pain and frequent bloody diarrhea. There was a continuous distribution of superficial erosion and ulceration by colonoscopy...

We report the case of an 81-year-old man taking dabigatran etexilate (dabigatran) for chronic atrial fibrillation, who presented with acute-onset hemoptysis and hypoxia. Chest high-resolution computed tomography showed bilateral ground grass opacities. After admission, his respiratory failure progressed rapidly and bronchoalveolar lavage was performed immediately, which showed copious amounts of bloody fluid and hemosiderin-laden macrophages with Prussian blue staining. He was diagnosed as having diffuse alveolar hemorrhage (DAH)...

The development of fingerprints in blood on a dark-coloured surface can be difficult. Contrast between the bloodmark and the surface can be difficult to achieve using photography and chemical reagents. The use of haem-reagent ortho-Phenylenediamine (OPD) and Zar-Pro™ strips in the enhancement of bloody impressions were investigated. Depletions of bloodmarks were deposited on black ceramic tiles and aged up to 90 days. OPD, Acid Yellow 7, and Hungarian Red were applied to these tiles and the developed fingermarks were compared using a numerical score system...

Inflammatory bowel diseases broadly categorized into Crohn's disease (CD) and ulcerative colitis (UC), are chronic inflammatory disorders of the gastrointestinal tract with increasing prevalence worldwide. The etiology of the disease is complex and involves a combination of genetic, environmental, immunological and gut microbial factors. Recurring and bloody diarrhea is the most prevalent and debilitating symptom in IBD. The pathogenesis of IBD-associated diarrhea is multifactorial and is essentially an outcome of mucosal damage caused by persistent inflammation resulting in dysregulated intestinal ion transport, impaired epithelial barrier function and increased accessibility of the pathogens to the intestinal mucosa...

There is an unmet need for methods to help in the early detection of cervical precancer. Optical spectroscopy-based techniques, such as Raman spectroscopy, have shown great potential for diagnosis of different cancers, including cervical cancer. However, relatively few studies have been carried out on liquid-based cytology (LBC) pap test specimens and confounding factors, such as blood contamination, have been identified. Previous work reported a method to remove blood contamination before Raman spectroscopy by pretreatment of the slides with hydrogen peroxide...

Acute acalculous cholecystitis (AAC) is most commonly seen after surgery in critically ill patients. Early diagnosis and treatment is the key in the management of AAC. Ultrasound is the commonly used first modality for right upper quadrant (RUQ) pain with sensitivity equal to or greater than 80% for AAC. Computed tomography (CT) scan is reported to have a sensitivity close to 90% and if both the ultrasound and CT scan are combined, it further increases the sensitivity for the diagnosis of AAC. It is unlikely for AAC to be present in the setting of both negative ultrasound and CT scan of the abdomen...

Nowadays, Klebsiella oxytoca is described as a causative organism for antibiotic-associated hemorrhagic colitis (AAHC). Here we report two cases of pediatric AAHC, from which K. oxytoca was cultured after starting amoxicillin-clavulanate or amoxicillin treatment. The patients developed severe abdominal pain and a large amount of bloody diarrhea. K. oxytoca was obtained in intestinal fluid culture of a boy through the colonoscopy. On the other hand, colonic tissue culture and intestinal fluid culture were negative of the other patient...

BACKGROUND: Differential diagnosis of inflammatory bowel disease is often very challenging. Paracoccidioidomycosis is a fungal disease that can mimic manifestations of Crohn's disease. CASE PRESENTATION: We report a case of a 13-year-old Caucasian boy with abdominal pain for 1.5 years associated with nausea, diarrhea, and weight loss of 10 kg. He presented increased C-reactive protein and an increased erythrocyte sedimentation rate. A colonoscopy showed deep serpiginous ulcers throughout his entire colon and rectum, which suggested Crohn's disease...
