Perforated viscous

Background and study aims  Submucosal (SM) injection is a critical step in endoscopic submucosal dissection (ESD). In Japan, use of viscous solutions such as sodium hyaluronate are recommended; the commercially product available is MucoUp (Seikagaku Co. and Boston Scientific Japan Co., Japan). Nevertheless, MucoUp is expensive and unavailable in many Western countries. For the past 8 years, we have been using low-cost sterile teardrops solution composed of 0.4 % sodium hyaluronate (Adaptis Fresh, Legrand Laboratory, Brazil)...

PURPOSE: To present the first clinicopathological report of Tintelnotia destructans keratitis, a filamentous fungus and as of yet uncommon virulent ocular pathogen. METHODS: A 70-year-old man presented with an infectious keratitis featuring a stromal infiltrate with feathery borders and a viscous hypopyon. Despite initial improvement under a combined therapy with natamycin and voriconazole, a perforation in the further course required a penetrating keratoplasty...

An analytical model based on the low reduced-frequency method is developed for the damping and spring force coefficients of micro-electro-mechanical systems (MEMS) structures. The model is based on a full-plate approach that includes thermal and viscous losses and hole end effects, as well as inertial and compressibility effects. Explicit analytical formulas are derived for damping and spring forces of perforated circular MEMS with open and closed edge boundary conditions. A thermo-viscous finite-element method (FEM) model is also developed for the numerical solution of the problem...

BACKGROUND: Spontaneous gas-forming pyogenic liver abscess (GFPLA) is a rare complication with a high fatality rate in spite of aggressive management. Clinical spectrum of GFPLA can mimic hollow viscus perforation as it usually accompanied by pneumoperitoneum and peritonitis. Up to now, GFPLA has not been well studied in Vietnam. CASE PRESENTATION: We reported here a case with pneumoperitoneum caused by ruptured liver abscess in a 41-year-old man with a history of treated duodenal ulcer and uncontrolled type II diabetes mellitus...

INTRODUCTION: Our case report describes a patient where multiple laparoscopies five years from initial presentation of symptoms were performed prior to laparotomy for benign multi-cystic peritoneal mesothelioma (BMPM), which has not been documented. PRESENTATION: A 61-year-old woman presented with years of chronic abdominal pain. Computerized tomography (CT) demonstrated a multi-cystic mass near the porta hepatis, and ultrasound was concerning for contained gallbladder perforation...

An additional length model is usually used to describe the reactive part of the impedance end correction of microperforated panels, which is extended to describe the resistive part. The cross-sectional impedance is computed along the axis of one perforation cell with a circular hole. Except for the obvious jumps in the narrow regions at the inlet and outlet of the perforation, the impedance varies linearly along the axis following exactly that of the viscous wave in the circular hole. The additional length for the impedance end correction is obtained by extrapolating the linearly varying impedance inside the hole...

BACKGROUND: Metastatic lesions from head and neck tumours to the small bowel are extremely rare, and metastasis from tongue squamous cell carcinoma in particular has been reported only twice in the English literature. CASE PRESENTATION: A 76 year-old lady diagnosed with a loco-regionally advanced tongue squamous cell carcinoma but deferred surgical resection. Seven months later after her diagnosis, she presented with generalized abdominal pain, due to image-proven viscous perforation, thus taken for emergent exploratory laparotomy, where the perforation was found at the distal ileum, which was resected, and a primary side to side anastomosis was done...

One of the main causes of adults' disability during their working age is multiple trauma. The process of medical care of patients who are injured seriously is still a challenging job. The primary treatment of these patients in the emergency medicine departments is the most required choice after the wilderness first aid and also would be very required before definitive care in the hospital. The main aim of emergency medicine departments is quick recognition and treatment of injuries which pose severe threat to patients' life in appropriate order of priority...

AIM: Precise bonding of attachments in aligner treatment is crucial to achieve the intended tooth movement. Thus, we evaluated five different bonding protocols for attachments used in aligner treatments with the goal of identifying the most precise protocol. METHODS: One ellipsoid and one rectangular attachment were exemplarily chosen and examined. All attachments were bonded using the same template aligner, which was produced by thermoforming. The bonding process was repeated 30 times with each protocol for statistical analysis...

Myxoglobulosis is a particular, rare, form of appendicular mucocele, characterized by the presence of numerous, occasionally calcified, globules that are grouped together like grapes, and look like pearls or fish eggs, in the appendicular lumen. The diagnosis of myxoglobulosis is most often fortuitous, but sometimes, can be made in the face of acute appendicitis or another setting of abdominal pain. Imaging (sonography or computerized tomography (CT)) is highly suggestive when it shows a cystic, encapsulated, oblong, well-delineated mass, containing (heterogeneous, liquid, and viscous) mucus with calcified globules...

A 7-day-old 600 grams baby with a post-conceptual age of 29 weeks presented with features suggestive of hollow viscous perforation, and was posted for an emergency laparotomy. In addition, she had a fractured indwelling umbilical arterial catheter which was planned for extraction in the same sitting. Radiological imaging showed that the catheter extended into the stump of the umbilical cord. She underwent exploratory laparotomy and ileal resection anastomosis, following which the stump was explored. However, the catheter could not be identified, and we suspected that it had embolised into the aorta...

BACKGROUND: Gastric duplication is a relatively rare congenital malformation, accounting for approximately 2.9-3.8% of gastrointestinal duplications. Gastric duplication cyst is a congenital anomaly that is rarely observed in adults. Accurate diagnosis of these cysts before resection is difficult. In this report, we describe a patient with gastric duplication cysts that were treated by laparoscopic resection. CASE PRESENTATION: A 46-year-old Japanese woman was referred to our institution because a cystic lesion in the pancreatic tail was detected by ultrasonography during a health examination...

Micro-perforated panels (MPPs) are widely used for broadband sound absorptions. For a MPP exposed to a grazing flow, existing acoustic impedance formulas based on different flow parameters give inconsistent results, thus calling for a systematic investigation of the issue to find more intrinsic flow parameters allowing for a reliable acoustic impedance prediction. In this study, three-dimensional CFD simulations are conducted on a MPP hole with a backing space in a flow duct. Numerical results allow identifying the flow velocity gradient in the viscous sublayer as the intrinsic flow parameter and show its linear relationship with a flow-related term in the acoustic resistance formula...

PURPOSE: To describe a novel surgical technique to remove retained subfoveal perfluorocarbon liquid (PFCL). METHODS: After setting up for 23-G pars plana vitrectomy, a 38-G flexible-tip macular hydrodissection cannula connected to the automated viscous fluid infusion kit was used to create a small retinotomy approximately 700 μm to 800 μm inferior to the fovea and induce macular detachment involving the retained PFCL bubble. The flexible cannula was bent at its junction with the shaft and was carefully advanced through the same retinotomy into the subretinal space to access and directly aspirate the retained subfoveal PFCL bubble...

Background: Natural orifice transluminal endoscopic surgery (NOTES) is a minimal invasive treatment. However, tissue dissection under endoscopy is still challenging due to the flexibility of endoscopy body and there is still no effective method for establishing a tunnel towards the targeted area. We previously showed that a new kind of thermogel could be submucosallly injected and served as a cushion for endoscopic dissection. Thus, in this study we investigated the feasibility and safety of tunnel creation using poly (lactic acid-co-glycolic acid)-poly (ethylene glycol)-poly (lactic acid-co-glycolic acid) (PLGA-PEG-PLGA) thermogel for NOTES in a porcine model...

High ascitic amylase concentration has been reported to be a characteristic of pancreatic ascites. However, values greater than 2000 U/l can also be seen in intestinal perforation. Fungal peritonitis is a serious entity that could also be caused by hollow viscous perforation. Herein we report a 22-year-old woman with epigastric pain, imitating an acute pancreatitis, and abdominal distention. Laboratory and radiological investigations revealed a high ascitic Amylase level with secondary fungal peritonitis due to gastric ulcer perforation...

Connective tissue diseases can be associated with rare gastrointestinal complications such as pneumatosis intestinalis and pneumoperitoneum. In this article, we report a unique case of recurrent pneumatosis intestinalis and spontaneous pneumoperitoneum without evidence of peritonitis in a patient with long-standing mixed connective tissue disease. Computed tomography scan of the abdomen and pelvis revealed pneumatosis of the jejunum and intra-abdominal free air, without evidence of perforation. The patient was managed non-operatively...

Metalmark butterfly (Riodinidae) diversity is heavily concentrated in the Neotropical lowland forests but despite their prevalence basic information on immature stages is still scarce. Here we describe the life cycle of seven taxa in the Rubiaceae-feeding section of the Mesosemiina, including three Mesosemia Hübner, [1819], three Leucochimona Stichel, 1909, and the first information for Semomesia Westwood, 1851. Immature stage morphology of Mesosemia cippus Hewitson, 1859 is described in detail through scanning electron microscopy...

Carcinosarcoma of the gallbladder (CSGB) is a rare clinical condition. To date, only 107 cases of CSGB have been reported worldwide. We present our experience of a late presentation of disseminated CSGB. To this we add a discussion of prognostic factors and treatment options for this rare gallbladder malignancy drawn from CSGB cases reported in the literature. Case report : A 73-year-old female presented to our facility with a poorly differentiated CSGB with widespread liver and peritoneal metastases. Fifteen days from the time of hospital admission, the patient suffered an acute episode of massive haematemesis with clinical signs of perforated viscous...

Spontaneous pneumomediastinum (SPM) is a rare and benign condition predominantly seen in young males. Patients present with non-specific pleuritic chest pain, cough, and dyspnea. Hence, it is difficult to diagnose in the acute setting until other serious differential diagnoses involving the integrity of the aerodigestive tract have been excluded. This results in over investigation and overtreatment until a diagnosis has been confirmed. We report a case of a 21-year-old Omani female who presented with a complaint of cough...
