Renocolic fistula is rare. Renal cyst infection is a serious complication in patients with autosomal dominant polycystic kidney disease (ADPKD). We present a case of refractory renal cyst infection due to renocolic fistula in a patient with ADPKD. A 65-year-old man with ADPKD on hemodialysis visited our hospital with complaints of fever and left abdominal pain. We diagnosed renal cyst infection with abdominal computed tomography scans. After hospitalization, gas shadow was observed in the left renal cyst. Percutaneous puncture of the cyst was performed...

We experienced a case of 1 patient who died from rhabdomyolysis-related complications after colonoscopy. A 60-year-old man had undergone an 'uncomplicated' colonoscopic polypectomy. Approximately 10 hours following this procedure, the patient complained of increasing left abdominal pain. His computed tomography image showed free gas, but his operative findings revealed no macroscopic perforation or abscess formation. Eight hours after the operation, the patient presented with myoglobulinuria, and we diagnosed the condition to be rhabdomyolysis...

Elucidating water-to-ice freezing, especially in "No Man's Land" (150 K < T < 235 K), is fundamentally important (e.g., predicting upper-troposphere cirrus-cloud formation) - and elusive. An oft-neglected aspect of tropospheric ice-crystallite formation lies in inevitably-present electric fields' role. Exploring nucleation in No Man's Land is technically demanding, owing to rapid nucleation rates, to mention nothing of difficulties of applying relevant electric fields thereto. Here, we tackle these intriguing open questions, via non-equilibrium molecular-dynamics simulations of sub-microsecond formation of rhombus-shaped ice Ic nano-crystallites from aggressively-quenched supercooled water nano-droplets in the gas phase, in external static electric fields...

A- 69-year-old man was admitted to a hospital with complaints of abdominal pain. Computed tomography showed hepatic portal venous gas and pneumatosis cystoides intestinalis. Conservative treatment was effective; however, after discharge, he developed complaints of vomiting. Fluoroscopic enteroclysis revealed a stricture in the jejunum necessitating admission to our hospital. Transoral balloon-assisted enteroscopy showed a circumferential ulcer with a stricture. The stricture was surgically resected, and a histopathological examination was consistent with ischemic enteritis...

Methane in exhaust gas from biogas upgrading process, which is a greenhouse gas, could cause global warming. The biofilter with immobilized methane-oxidizing bacteria (MOB) is a promising approach for methane removal, and the selections of inoculated MOB culture and support material are vital for the biofilter. In this work, five MOB consortia were enriched at different methane concentrations. The MOB-20 consortium enriched at the methane concentration of 20.0% (v/v) was then immobilized on sponge and two particle sizes of volcanic rock in biofilters to remove methane in exhaust gas from biogas upgrading process...

A 47-year-old man underwent hematopoietic stem cell transplantation for malignant lymphoma. He developed acute skin graft versus host disease(GVHD)and pneumomycosis which were treated with steroids. One hundred and fifteen days later, the patient had a diagnosis of free gas images in the abdominal cavity and streakly air collections in the bowel wall from the ascending colon to the sigmoid colon in the CT scan. He was asymptomatic and his physical examination was unrevealing. We diagnosed his condition as pneumatosis cystoides intestinalis(PCI)...

We here describe a case of an acute peritonitis due to perforation of a small intestine tumor metastasized from a lung cancer. A 66-year-old man who had undergone a bladder cancer procedure 2 years ago and was hospitalized for the second operation, complained sudden abdominal pain. An enhanced abdominal CTrevealed a small amount of free gas and ascites in the abdominal cavity. On the same day, emergency exploratory surgery was performed with the diagnosis of perforative peritonitis. A laparotomy revealed a jejunal tumor with perforation 40 cm distal from the Treitz ligament...

Understanding water solidification, especially in "No Man's Land" (NML) (150 K < T < 235 K) is crucially important (e.g., upper-troposphere cloud processes) and challenging. A rather neglected aspect of tropospheric ice-crystallite formation is inevitably present electromagnetic fields' role. Here, we employ non-equilibrium molecular dynamics of aggressively quenched supercooled water nano-droplets in the gas phase under NML conditions, in externally applied electromagnetic (e/m) fields, elucidating significant differences between effects of static and oscillating fields: although static fields induce "electro-freezing," e/m fields exhibit the contrary - solidification inhibition...

RATIONALE: Pneumatosis cystoids intestinalis (PCI) is a rare disease in which gas develops in the mucosa or submucosa of the digestive tract. The etiology and pathogenesis of this disease, at present, remain unclear, and gastrointestinal malignant neoplasms may be a potentially important cause. Herein, we report a case of mantle cell lymphoma presenting as PCI as well as present a literature review of cases of suspect PCI that was definitively diagnosed as gastrointestinal neoplasms. In doing so, we highlighted cases of neoplastic pathogenesis that present as PCI...

A 78-year-old man with acute right lower abdominal pain and nausea was referred to our hospital. Computed tomography (CT) demonstrated hepatic portal venous gas and a thickened wall of the terminal ileum, and colonoscopy demonstrated ulcers and erosions of the ileocecal region. Histological examination of biopsy samples revealed basophilic crystals consistent with the component of calcium polystyrene sulfonate (CPS). This patient started taking CPS 2 months prior for chronic hyperkalemia. The symptoms resolved soon after ceasing CPS, and subsequent imaging studies confirmed the disappearance of the portal venous gas and ileocolitis...

Recently, growing earthquake activity in the northeastern Netherlands has aroused considerable concern among the 600,000 provincial inhabitants. There, at 3 km deep, the rich Groningen gas field extends over 900 km2 and still contains about 600 of the original 2,800 billion cubic meters (bcm). Particularly after 2001, earthquakes have increased in number, magnitude (M, on the logarithmic Richter scale), and damage to numerous buildings. The man-made nature of extraction-induced earthquakes challenges static notions of risk, complicates formal risk assessment, and questions familiar conceptions of acceptable risk...

Fire safety is a concern in space travel, particularly with the current plans of increasing the length of the manned space missions, and of using spacecraft atmospheres different than in Earth, such as microgravity, low-velocity gas flow, low pressure and elevated oxygen concentration. In this work, the spread of flame over a thermoplastic polymer, polymethyl methacrylate (PMMA), was conducted in the International Space Station and on Earth. The tests consisted of determining the opposed flame spread rate over PMMA cylinders under low-flow velocities ranging from 0...

A 25-year-old man suffered from consciousness change was sent to our emergency department by friends who reported that they were not sure what had happened to him. Physical examination revealed bilateral pupils dilatation, lethargy, slurred speech, and ataxia. Computer-aided tomographic scan of the brain revealed no definite evidence of intracranial lesions. Routine laboratory tests revealed total physiological turmoil. Despite immediate commencement of aggressive treatment, the patient's condition deteriorated long before the traditional drug screen provided an answer for the identities of the multiple drugs overdose...

Nasal nitric oxide (nNO) measurement is a diagnostic test for primary ciliary dyskinesia (PCD). Here, we have shown the development of unilateral PCD-like symptoms associated with low nNO. A 60-year-old man had been previously healthy but developed unilateral, severe pansinusitis. He required surgical drainage of all left sinuses, and biopsies showed loss of the ciliated epithelium. At 4 weeks, he had unilateral (left-sided), profuse, clear rhinorrhea characteristic of PCD, and his surgical ostia were all patent endoscopically...
