Transmesenteric hernia after laparoscopic-assisted sigmoid colectomy. (1/407)

BACKGROUND AND OBJECTIVES: Laparoscopic-assisted surgery has been applied for a variety of colonic surgery. The objective of this paper is to demonstrate a possible and avoidable complication of laparoscopic colonic surgery. CASE PRESENTATION: A 47-year-old woman underwent gasless laparoscopic-assisted sigmoid colectomy. On the 20th postoperative day, she developed bowel obstruction. Decompression with a long tube failed to resolve the bowel obstruction. Open laparotomy was performed. Abdominal exploration revealed a loop of the small bowel incarcerated in the mesenteric defect caused by the previous operation. Adhesiolysis was performed, and the postoperative course was uneventful. DISCUSSION: Despite technical difficulty, complete closure of the mesentery after bowel resection is strongly recommended for prevention of transmesenteric incarcerated hernia after laparoscopic surgery.  (+info)

Ring-down artifacts posterior to the right hemidiaphragm on abdominal sonography: sign of pulmonary parenchymal abnormalities. (2/407)

The aim of our study was to verify whether ring-down artifacts posterior to the right hemidiaphragm on abdominal sonography reflected pulmonary parenchymal abnormalities. Forty patients (group 1) with abdominal diseases and 32 patients (group 2) with proved various pulmonary abnormalities involving the right lung base underwent abdominal sonography with 2-4 MHz transducers. In these two groups, the presence and number of ring-down artifacts were assessed and correlated with peridiaphragmatic lung findings on chest radiographs or computed tomographic scans. In 21 patients (group 3) with multiple (more than five) or numerous (10 or more) ring-down artifacts, chest radiographs were reviewed to see if any peridiaphragmatic pulmonary abnormalities were present. In group 1, one or several (less than five) ring-down artifacts were shown in 27 of 40 (68%) patients. In these patients, computed tomography showed insignificant focal intra- and interlobular septal thickening in the peridiaphragmatic right lung. In group 2, 31 of 32 (97%) patients showed multiple or numerous ring-down artifacts. In group 3, chest radiographs showed various pulmonary abnormalities in 20 of 21 (95%) patients, including emphysema, idiopathic interstitial pneumonia, bronchopneumonia, and interstitial edema. Although nonspecific, ring-down artifacts posterior to the right diaphragm on abdominal sonography may be used to predict pulmonary abnormalities when encountered on abdominal sonography in patients without specific pulmonary symptoms.  (+info)

Altered abdominal fat distribution and its association with the serum lipid profile in non-diabetic haemodialysis patients. (3/407)

BACKGROUND: Disturbances of lipid and carbohydrate metabolism may be associated with the distribution of abdominal adiposity. However, little is known about the alteration of abdominal adiposity and its association with the serum lipid profile in haemodialysis patients. METHODS: We evaluated the distribution of abdominal adiposity by using computed tomography and examined its relationship with the serum lipid profile in 92 non-diabetic haemodialysis patients and 80 control subjects with normal renal function. Since the mean body mass index (BMI) and total body fat mass were significantly lower in the haemodialysis patients than in the control subjects, the subcutaneous abdominal fat area and the visceral fat area were standardized by body mass index and compared between the haemodialysis patients and the control subjects. RESULTS: Mean subcutaneous fat area/body mass index (SFA/BMI) was significantly lower, and mean visceral fat area/body mass index (VFA/BMI) was significantly higher in the haemodialysis patients (SFA/BMI, 2.40+/-0.12; VFA/BMI, 2.28+/-0.15) than in the control subjects (SFA/BMI, 3.75+/-0.21, P<0.01; VFA/BMI, 1.65+/-0.15, P<0.01). Consequently, visceral fat area/ subcutaneous fat area ratio was significantly higher in the haemodialysis patients (1.05+/-0.07) than in the control subjects (0.46+/-0.04, P<0.01). A scattered plot of visceral fat area relative to BMI revealed that visceral fat area was higher in the haemodialysis patients than in the control subjects at any BMI level. A simple regression analysis showed that BMI, total body fat mass, subcutaneous fat area and visceral fat area were all associated with serum triglycerides and the atherogenic index, (total cholesterol-HDL cholesterol)/HDL cholesterol. Furthermore, a multiple regression analysis indicated that the visceral fat area was the best predictor for either the atherogenic index or triglycerides among these fat components. CONCLUSIONS: These data indicate that haemodialysis patients exhibited a visceral fat accumulation irrespective of BMI, and this shift of abdominal adiposity might be associated with disturbance of the serum lipid profile in non-diabetic haemodialysis patients.  (+info)

Screening admission CT scans in patients with AIDS--a randomized trial. (4/407)

OBJECTIVE: To determine if the length of hospital stay could be reduced for patients with AIDS by performing screening head and abdominal-pelvic computed tomography (CT) scans within 24 hours of admission, regardless of presenting signs and symptoms. DESIGN: Randomized, prospective trial. SETTING: Tertiary, academic medical center. PATIENTS: On presentation to the emergency department, 42 patients with AIDS were identified as being eligible to participate in our study. Twenty-two patients consented to participate and were assigned to screening CT or control group. INTERVENTION: Patients assigned to the screening CT group had head and abdominal-pelvic CT scans within 24 hours of admission, regardless of presenting signs or symptoms. The findings of the screening CT scans were immediately communicated to the patient's referring physician. Patients assigned to the control group had CT studies done solely at the discretion of their physician. MAIN OUTCOME MEASURE: Length of stay for patients in the screening CT and control groups. RESULTS: The average length of stay for patients in the screening CT group was 1.3 days longer than the average length of stay for patients in the control group (95% CI, 1.4 days shorter to 4 days longer). The study was terminated after 22 patients were enrolled. CONCLUSION: Screening CT scans of the head and abdomen and pelvis at the time of hospital admission do not reduce the length of stay for patients with AIDS.  (+info)

The role of positron emission tomography (PET) in the management of lymphoma patients. (5/407)

BACKGROUND: Treatment of both Hodgkin's disease (HD) and aggressive non-Hodgkin's lymphoma (NHL) with abdominal presentation at the time of diagnosis is often followed by detection of residual masses by computed tomography (CT). However, CT is usually unable to discriminate between residual tumor and fibrosis/necrosis. We investigated the ability of fluorine-18 fluorodeoxyglucose positron emission tomography (PET) to differentiate between residual active tumor tissue and fibrosis. PATIENTS AND METHODS: Forty-four patients with HD or aggressive NHL presenting abdominal involvement (41% with bulky mass) were studied with CT and PET at the end of chemotherapy +/- radiation therapy. RESULTS: After treatment, seven patients had negative PET and CT, and none of them relapsed. The remaining 37 patients all had positive CT (abnormalities < or = 10%). All of the 13 who also had positive PET relapsed (100%). By contrast, there was only 1 (4%) relapse among the 24 patients who were positive at CT but negative at PET. The two-year actuarial relapse-free survival rate was 95% for those with negative PET compared with 0% for positive PET patients (P < 0.000000). CONCLUSIONS: In lymphoma patients with abdominal masses who present CT positivity at restaging, PET should be considered the noninvasive imaging modality of choice for differentiating early recurrences or residual disease from fibrosis.  (+info)

Renal artery lesions in patients with moyamoya disease: angiographic findings. (6/407)

BACKGROUND AND PURPOSE: Renal artery lesions in moyamoya disease have been described sporadically in several case reports. The purpose of this study is to evaluate the angiographic findings of renal artery lesions in moyamoya disease and to determine the prevalence of renal artery lesions in patients with moyamoya disease. METHODS: Eighty-six consecutive patients with idiopathic moyamoya disease were prospectively examined with both cerebral angiography and abdominal aortography. The findings of abdominal aortography were reviewed for the presence and appearance of renal artery lesions and compared with the clinical data and cerebral angiographic findings. RESULTS: Of 86 patients with idiopathic moyamoya disease, 7 patients (8%) were found to have renal artery lesions. Six patients (7%) had stenosis in the renal artery, and 1 patient (1%) had a small saccular aneurysm in the renal artery. Two patients (2%) with a marked renal artery stenosis presented with renovascular hypertension, which resulted in an intraventricular hemorrhage in 1 patient. Furthermore, the renal artery stenosis in the 2 patients with renovascular hypertension was successfully treated with percutaneous transluminal angioplasty. There was no significant correlation between the presence of renal artery lesions and cerebral angiographic findings. CONCLUSIONS: Seven (8%) of 86 patients with moyamoya disease showed renal artery lesions, including 6 stenoses (7%) and 1 aneurysm (1%). Renal artery lesions are a clinically relevant systemic manifestation in patients with moyamoya disease.  (+info)

Primary epitheliotropic T-cell lymphoma of the urinary bladder in a dog. (7/407)

A 7-year-old, intact female mixed-breed dog was presented for evaluation of hematuria. Physical examination revealed a suprapubic mass. Ultrasonographic examination showed a large lobular mass occupying the urinary bladder. At the owners' request, the dog was euthanatized and a postmortem examination was performed. Necropsy confirmed the presence of a lobular mass of about 5- to 6-cm diameter protruding into the lumen of the bladder. Histologically, the mass was composed of a large number of atypical lymphoid cells in the lamina propria and mucosal epithelium. Immunohistochemically, the neoplastic cells expressed CD3 but not CD79alpha or keratin and vimentin, supporting a diagnosis of T-cell lymphoma.  (+info)

What is heartburn worth? A cost-utility analysis of management strategies. (8/407)

OBJECTIVE: To determine the best treatment strategy for the management of patients presenting with symptoms consistent with uncomplicated heartburn. METHODS: We performed a cost-utility analysis of 4 alternatives: empirical proton pump inhibitor, empirical histamine2-receptor antagonist, and diagnostic strategies consisting of either esophagogastroduodenoscopy (EGD) or an upper gastrointestinal series before treatment. The time horizon of the model was 1 year. The base case analysis assumed a cohort of otherwise healthy 45-year-old individuals in a primary care practice. MAIN RESULTS: Empirical treatment with a proton pump inhibitor was projected to provide the greatest quality-adjusted survival for the cohort. Empirical treatment with a histamine2 receptor antagonist was projected to be the least costly of the alternatives. The marginal cost-effectiveness of using a proton pump inhibitor over a histamine2-receptor antagonist was approximately $10,400 per quality-adjusted life year (QALY) gained in the base case analysis and was less than $50,000 per QALY as long as the utility for heartburn was less than 0.95. Both diagnostic strategies were dominated by proton pump inhibitor alternative. CONCLUSIONS: Empirical treatment seems to be the optimal initial management strategy for patients with heartburn, but the choice between a proton pump inhibitor or histamine2-receptor antagonist depends on the impact of heartburn on quality of life.  (+info)

In an effort to develop referral criteria for the ordering of abdominal radiographs for patients presenting with abdominal symptoms, we prospectively studied the relation between clinical data and radiographic abnormalities. Of 1780 examinations, 179 (10.0%) showed some radiographic abnormality. If abdominal radiographs would have been limited to those patients who had moderate or severe abdominal tenderness, or to patients with a high clinical suspicion of bowel obstruction, renal or ureteral calculi, trauma, ischemia, or gallbladder disease, regardless of the degree of tenderness, 956 (53.7%) examinations would not have been done. All radiographic abnormalities reflecting a serious pathologic process would have been identified. Only 33 (3.5%) abnormalities of limited significance, almost all localized or generalized ileus, would have been undetected. The adoption of these referral criteria would result in minimal loss of clinically useful information, large financial savings, and a reduction ...
The term gossypiboma denotes a mass of cotton that is retained in the body following surgery. Gossypiboma is a medico-legal problem especially for surgeons. To the best of our knowledge, the patient presented herein is the second reported patient in whom the exact site of migration of a retained surgical textile material into the intestinal lumen could be demonstrated by preoperative imaging studies. A 74-year-old woman presented with symptoms of small bowel obstruction due to incomplete intraluminal migration of a laparotomy towel 3 years after open cholecystectomy and umbilical hernia repair. Plain abdominal radiography did not show any sign of a radio-opaque marker in the abdomen. However, contrast enhanced abdominal computerized tomography revealed a round, well-defined soft-tissue mass with a dense, enhanced wall, containing an internal high-density area with air-bubbles in the mid-abdomen. A fistula between the abscess cavity containing the suspicious mass and gastrointestinal tract was

Once identified, 2 endoscopic marking clips were attached to the colonic mucosa, and 400 to 500 ml of radiographic contrast medium was injected to produce an air-contrast enema.. These clips were subsequently localized using plain abdominal radiography, assessed by a single experienced radiologist who was blinded to the colonoscopic findings.. A total of 29 consecutive patients were enrolled in the study. The research team found that the overall accuracy of MEI, when compared to the air-contrast enema was 90%. They identified 3 slight errors of localization: clips localized to the descending rather than the sigmoid-descending colon junction (1), or to either side of the mid-transverse (1) and hepatic flexure (1).. However, these were not considered to be of surgical or clinical importance.. Dr Shahs team concluded, MEI is a reliable and accurate method for determining the anatomical position of the endoscope tip during colonoscopy. When it becomes commercially available, we believe the ...

HISTORY. A fourteen-year-old intact male Irish setter weighing 31 kg, was presented to the Murcia University Veterinary Teaching Hospital with an inguinal swelling of twelve months of duration, although in the last four months the swelling had grown. On clinical examination the dog appeared bright, alert and a large, non-painful caudal abdominal mass was palpated. The mass was causing right-sided deviation of the penis and prepuce. In addition, the presence of the mass in the left caudal flank and inguinal region required circumduction of the left pelvic limb during locomotion. Haematology and serum biochemistry values were within normal ranges. Abdominal radiography revealed a large fat-dense mass in the mid to caudal abdomen, displacing the intestines cranially and dorsally. Thoracic radiographs were unremarkable. Abdominal ultrasound confirmed the presence of a fat-echogenic mass. Cytological analysis of fine needle aspirate of the mass revealed adipose tissue. Surgical excision was performed ...
Digestive foreign bodies (DFBs) are medical and surgical emergency because of clinical manifestations and the risk of perforation [1-3]. Foreign bodies (FBs) ingestion occurs at both extremes group age of life. The frequency and nature of FBs ingested vary from one study to another but mainly according to the patients age group and his actual health status [3-5]. In Kalemie, the management of FBs ingestion is medical or surgical. We report the case of ingestion of the set key and key holder in a 3-year-old boy. The management was medical based on an exceptional diet, followed by spontaneous elimination. To our knowledge, we describe the first case of FBs ingestion management by food in an asymptomatic patient.. A 3-year-old boy was admitted for ingestion of FBs in Camp Marin Hospital of Kalemie. He was asymptomatic and had no medical or surgical history. Physical examination was normal. The chest and abdominal radiography requested could not be done as the x-ray machine was faulty. No ...
The patient was re-evaluated and the possibility of a primary melanoma at any other site, mainly skin, eye, and gastrointestinal tract was ruled out; so primary ovarian melanoma was confirmed. After being reviewed by a medical oncologist specialising in melanoma care, the patient was advised that adjuvant therapy would not be necessary. A follow-up was arranged at our outpatient clinic. We observed a normalization of CA19.9 within 3 weeks. Seventeen days after the first surgery the patient was hospitalized with abdominal pain. The clinical evaluation, abdominal radiography and abdominal ultrasound did not show any evidence of disease. The clinical follow-up, performed 3 months after surgery, did not show any signs of illness. The markers were fully normalized. Additional 4 months after, the patient came to our emergency service presenting abdominal pain. Clinical examination showed the presence of a solid pelvic mass of 4.3×3.3 cm. CA125 was 26 U/mL and CA19.9 was 3 U/mL. The tomography scan ...
It has been reported that the causes of horizontal duodenal perforation are trauma or iatrogenic injury due to ERCP mainly. Duodenal injury is present, on average, in 3.7-5% of abdominal injuries and may be due to either blunt trauma of the abdomen or penetrating injuries [6]. Though incidence of iatrogenic injuries during upper gastrointestinal endoscopy alone is extremely rare, it is significantly higher in ERCP, estimated to be between 0.4 and 1% [5, 7].. Chest and erect abdominal radiography and ultrasonography are not of diagnostic value, and the modality of choice is CT scan with both oral and intravenous contrast media [2, 3]. Factors like anatomical location of the injury, type and extent of injury, associated injuries to other structures and organs, and time of surgery determine the type of surgical options and their outcome [8]. The American Association for the Surgery of Trauma has suggested the Organ Injury Scale [9], but the grading may not always dictate the management [1]. ...
An elderly woman in Bogota was checked into a hospital after reporting a strong headache and diarrhea, leading doctors to discover a 32-week developed fetus from a pregnancy that took place 40 years ago.. An 82-year-old patient who arrived at emergency services on December 8 with diarrhea and in the medical exam the medic who was looking over (the patient) noted something abnormal in her abdomen and ordered an exam thinking that perhaps it was gallstones. An ultrasound was done and it wasnt positive. Then, an abdominal radiography was ordered which located a tumour in the abdominal cavity which concluded that it was a fetus in the womans abdomen, said Dr. Kemer Ramirez to local media.. The situation was caused by a rare condition known as lipedion that affects one out of five million pregnancies.. Litopedion is a form of ectopic pregnancy where the fetus doesnt develop in the uterus but rather in the abdominal. The condition doesnt show symptoms leaving the mother unaware of the presence ...

TY - GEN. T1 - A fixed-point model for pancreas segmentation in abdominal CT scans. AU - Zhou, Yuyin. AU - Xie, Lingxi. AU - Shen, Wei. AU - Wang, Yan. AU - Fishman, Elliot K. AU - Yuille, Alan L.. PY - 2017. Y1 - 2017. N2 - Deep neural networks have been widely adopted for automatic organ segmentation from abdominal CT scans. However, the segmentation accuracy of some small organs (e.g., the pancreas) is sometimes below satisfaction, arguably because deep networks are easily disrupted by the complex and variable background regions which occupies a large fraction of the input volume. In this paper, we formulate this problem into a fixed-point model which uses a predicted segmentation mask to shrink the input region. This is motivated by the fact that a smaller input region often leads to more accurate segmentation. In the training process, we use the ground-truth annotation to generate accurate input regions and optimize network weights. On the testing stage, we fix the network parameters and ...
The diagnosis is essentially clinical but is assisted by the finding of a leucocytosis of up to 20,000-30,000/mm3. The findings on a plain abdominal radiograph are usually non- specific. Arteriography may be used to confirm the diagnosis provided it does not delay the urgent vascular surgery necessary to prevent gangrene. Unfortunately extensive resection of the small intestine is necessary in many patients and the overall mortality is 50 ...

An abdominal X-ray is taken by a radiology technologist. The X-ray pictures are read by a radiologist. Some other doctors, such as emergency room doctors, can also look at abdominal X-rays to check for common problems, such as a blocked intestine.. You may need to take off all or most of your clothes. You will be given a gown to use during the test.. You will lie on your back on a table. A lead apron may be placed over your lower pelvic area to protect it from the X-ray. A womans ovaries cannot be protected during this test because they lie too close to the belly organs that are X-rayed. A mans testicles can sometimes be protected during the test.. After the X-ray machine is positioned over your belly, you will be asked to hold your breath while the X-ray pictures are taken. You need to lie very still so the pictures are clear.. Many times, two pictures are taken: one while you are lying down (supine) and the other one while you are standing (erect view). The erect view can help find a ...

TY - JOUR. T1 - Coupled Polymer-Membrane Equilibration and Cavity Ring-down Spectrometry for the Highly Sensitive Determination of Dissolved Methane in Environmental Waters. AU - Munksgaard, Niels. AU - Nelson, Paul. PY - 2021/2/11. Y1 - 2021/2/11. N2 - High sensitivity field-based analysis of dissolved methane in surface water and groundwater is needed to monitor the environmental impacts of natural gas-field development and understand microbial carbon cycling in water bodies. A new analytical technique using a polymer membrane contactor coupled to a laser-based cavity ring-down spectrometer was developed and tested. By recirculating a water sample for approximately 10 mins, equilibrium was established between dissolved methane in the sample and methane in the measured gas phase according to Henrys Law. The performance of the system was investigated by replicate analyses of several different water samples, spike recovery tests, comparison to analysis by head-space gas chromatography, and ...
You may have heard of other imaging exams and wonder why your doctor chose a CT scan over other options.. Your doctor may choose a CT scan over an MRI (magnetic resonance imaging) because a CT scan is faster than an MRI. Plus, if youre uncomfortable in small spaces, a CT scan would likely be a better choice. MRIs requires you to be inside an enclosed space while loud noises occur all around you. In addition, an MRI is more expensive than a CT scan.. Your doctor may choose a CT scan over an X-ray because it provides more detail than an X-ray does. A CT scanner moves around your body and takes pictures from many different angles. An X-ray take pictures from one angle only. So, a CT scan is able to provide more information than an X-ray can.. ...

Dear Editor,. We present a case of mucinous gastric carcinoma which is a rare histological subtype of gastric cancer. It is characterized by the presence of a mucus-secreting adenocarcinoma with lakes of intercellular mucin (1,2). We would like to emphasize the importance of this lesion in the differential diagnosis when calcifications in the upper left quadrant are observed in the imaging techniques.. Case report. A 73-year old man with no past medical history was admitted for general syndrome. An abdominal CT scan showed a gastric tumor with miliary punctate calcifications (Fig. 1) and a large gastric neoplasm was found at the gastroscopy. Without evidence of vascular invasion or adenopathy neither surgical contraindication, a Billroth-II subtotal gastrectomy was performed. In the tissue removed surgically a whitish formation covering the external surface of the stomach was observed. Inside there was a 9 x 12 cm tumoral mass. The histopathological analysis revealed an adenocarcinoma with lakes ...

The CT features of this condition have not been systematically investigated. Objective: Defining benign pneumatosis intestinalis as pneumatosis intestinalis that resolved with medical management alone, we sought to: (1) determine whether the incidence of benign pneumatosis intestinalis had increased at our pediatric cancer hospital; (2) characterize CT features of benign pneumatosis intestinalis; and (3) determine the relationship between imaging features and clinical course of benign pneumatosis intestinalis in ...
Plaster ingestion forming gastric bezoar is a strange way to attempt suicide and this method has not yet been reported. It may lead to a mechanical obstruction of the gut, especially the pyloric region, and could manifest with abdominal pain, epigastric distress, nausea, vomiting, and fullness. Herein we report a case of a 37 year-old woman presenting with plaster ingestion and gastric outlet obstruction, who underwent surgery. At six months follow-up the patient was fully recovered. Plaster has no toxic or erosive effects. Endoscopic or surgical removing of such material is recommended. Moreover, psychiatric intervention and management is imperative to prevent recurrence in such cases.

Pavlidis, K.S. Atmatzidis,.SUMMARY Intestinal intussusception in adults is usually secondary, rather than primary as in infants. It may lead to obstruction and even strangulation with necrosis. To present our experience on this unusual situation and review the relevant bibliography is the aim of this study. A retrospective survey over the past twelve years found seven patients with acute intestinal intussusception (median age of 56 years, range 28 to 75), among 368 cases of operated intestinal obstruction (1.9%). Clinical examination and plain abdominal radiography made the pre-operative diagnosis of obstructive ileus. The intra-operative diagnosis of intussusception included ileo-cecal (n=4), ileo-iliac (n=2) and jejuno-jejunal (n=1) type. Operation was reduction with removal of the causative factor (n=5) and

PURPOSE The aim of this study was to describe the epidemiologic, diagnostic, and therapeutic aspects of surgical abdominal emergencies in a teaching hospital in a developing country (Togo). MATERIAL AND METHOD This retrospective study included the medical files of all patients managed for surgical abdominal emergencies from March 1, 2002, to March 1, 2012. RESULTS The study included 594 patients, with a mean age of 30.3 years (range: 1 month to 80 years) and a 2.1 male:female sex ratio. The emergencies were acute generalized peritonitis (54.5%), intestinal obstruction (26.6%), acute appendicitis (14.5%), and abdominal trauma (4.4%). Plain abdominal radiographs were taken for 414 patients with acute generalized peritonitis (324 cases) and intestinal obstructions without a strangulated hernia (90 cases). Nine patients had abdominal ultrasounds for abdominal trauma (5 cases) and appendicular abscess (4 cases). No abdominal CT scan was performed. All patients underwent surgery, 316 (53.2%) by physician
A 2-year-old boy presented to our childrens hospital with a 5-day history of fever and 2 days prior to admission he progressively developed a maculopapular rash in thorax and genitals, had erythema and edema in palms and soles, bilateral conjunctival injection, swollen red lips, and a strawberry tongue. On the day of admission he developed a distended and painful abdomen, diarrhea, and vomiting. On examination he was febrile (39.8 C), heart rate was 180 beats/minute, met 5 major clinical diagnostic criteria for KD, and also presented a diffusely distended tender but soft abdomen, with no rebound sign. He received 1 dose of IVIG [2 g/Kg] and was started on acetylsalicylic acid (ASA) [100 mg/Kg/day]. Because of persistent abdominal distention and vomiting, a plain abdominal radiograph was performed which showed air fluid levels with diffuse small bowel loops distention, all of these consistent with an intestinal pseudoobstruction. An abdominal ultrasound revealed gallbladder hydrops, fluid-filled ...
To estimate changes in the age- and gender-specific prevalence of Pagets disease in Britain, we performed a radiographic survey of the disorder in 10 British centers, using sampling and radiographic methods identical to a study performed in 1974. In each center, a sample of abdominal radiographs of people aged 55 years and over was taken from stored films within the radiology department of the principal general hospital. The radiographs were identified by screening radiographic records over the period 1993-1995. Any abdominal radiograph in a subject aged 55 years and over which included the entire pelvis, sacrum, femoral heads, and all lumbar vertebrae was studied. The radiographs were evaluated by a trained observer and the consultant radiologist who participated in the original 1974 survey. Nine thousand eight hundred and twenty-eight radiographs (4625 men, 5203 women) were assessed in the 10 towns. The overall age/gender standardized prevalence rate was 2%, with a male/female ratio of 1.6.

Along with red cells, radiation sickness can reduce the risk of infection-fighting white cells in the body. As a result, the risk of bacterial, viral, and fungal infections is heightened.. The average radiation dose from an abdominal X-ray is 1.4 mGy, that from an abdominal CT scan is 8.0 mGy, that from a pelvic CT scan is 25 mGy, and that from a selective CT scan of the abdomen and the pelvis is 30 mGy.. It is again interesting to note that an abdominal and pelvic CT scan can cause symptoms similar to the category of cerebrovascular syndrome, even though this radiation exposure is supposed to be therapeutic.. The three categories are as follows:. 1. The cerebrovascular (brain) syndrome - This is when the total dose of radiation is extremely high, exceeding 20-30 Gy. A person with cerebrovascular (brain) syndrome rapidly develops confusion, nausea, vomiting, bloody diarrhea, and shock. Within hours their blood pressure falls due to heart and circulatory damage, accompanied by the inability to ...

Synposis - This was a planned subanalysis of a prospective, multicenter observational study of children ≤ 18 years of age with blunt torso trauma conducted in 20 EDs in the PECARN. They had clinicians document their suspicion for the presence of intra-abdominal injuries needing acute intervention (defined as death due to abdominal injury, surgical intervention, angiographic embolization, blood transfusion secondary to intra-abdominal hemorrhage, or IV fluids x2 nights in patients with pancreatic or GI injury) as , 1% (low-risk), 1-5%, 6-10%, 11-50%, or ,50% prior to knowledge of abdominal CT scanning. Their total population was 11,919 patients. IAI undergoing acute intervention was diagnosed in 203 (2%) of patients. Abdominal CT scans were obtained in 2,302/2,667 (86% 95% CI 85-88%) with clinician suspicion ≥ 1% and in 3,016/9252 (33% 95% CI 32-34%) with clinician suspicion ,1%. Sensitivity and specificity of the clinical decision rule for IAI requiring acute intervention was 97% (95% CI ...
The impaction of dental prostheses in either the airway or esophagus is an under-recognized problem which may result in severe morbidity or even mortality. The radio-opacity and the size of fixed and removable dental prostheses in an animal carcass was investigated. Prostheses were placed one at a time in the oro-laryngopharynx or in tho trachea and the esophagus. Lateral radiographs were taken for each prosthesis in site. The radio-opacity and size of the prostheses on the radiograph was graded. Most of the prostheses investigated were radio-opaque though the removable prostheses were more likely to be radiolucent and differ in size. In a symptomatic patient with a missing dental prosthesis, a negative chest or abdominal radiograph does not exclude impaction, inhalation or ingestion. Further evaluation with endoscopy or even computed tomography may be essential to reduce the possibility of severe morbidity or even mortality.. ...
The small intestine comprises the duodenum, jejunum and ileum. On a lateral abdominal radiograph, the small intestine occupies most of the mid-ventral abdomen, lying caudal to the stomach and cranial to the bladder. It appears as smoothly curving tubes in long axis views and as circular or ring-shaped opacities in cross section. Peristaltic waves cause transient segmental narrowing, which may be recognized on plain radiographs. The duodenum runs cranially and laterally from the pylorus and then turns caudally, forming the cranial duodenal flexure. The flexure is held against the caudal surface of the right liver lobes by the hepatoduodenal ligament. The descending duodenum runs dorsally and caudally along the right abdominal wall, before turning medially at the caudal duodenal flexure. The ascending duodenum runs cranially and to the left of midline, where it becomes the jejunum at the duodenojejunal junction. The duodenum may occasionally be recognized on a plain radiograph from its characteristic

Hemangiosarcoma (HSA) is an aggressive, malignant cancer of blood vessels that often grows as a mass in the spleen, liver, or heart, but can also be found growing in other places in the body. Animals usually present to their veterinarian for sudden collapse due to internal bleeding from the mass. In most cases, by the time the animal is showing clinical signs, the cancer has spread to other areas of the body, such as the lungs. Diagnosis of HSA is suggested by chest and abdominal radiographs (x-rays), abdominal ultrasound and aspiration of abdominal fluid, and biopsy of the mass via exploratory surgery.. ...

Incidental adrenal masses seen on abdominal CT scans of low-risk patients are almost always benign and do not need any imaging follow-up, according to a large study of patients. This finding is significant because incidental adrenal lesions are seen in about 5 percent of CT examinations, study authors say.
Background: Von-Hippel Lindau (VHL) syndrome is a rare genetic disorder that predisposes individuals to benign and malignant tumors, including pancreatic neuroendocrine tumors and renal cell carcinoma. Guidelines recommend abdominal Computed Tomography (CT) scans to be performed every one or two years starting in adolescence or young adulthood for screening or surveillance for these tumors.. Objective: To assess radiation exposures resulting from alternative strategies of screening and surveillance by abdominal CT scans, and projecting potential cancer risks subsequent to these exposures.. Methods: Organ radiation doses were estimated using a dedicated computational solution for CT dosimetry, on the basis of protocols routinely used at one U.S. cancer research center in 2012-2015. Subsequent Lifetime Attributable Risks (LARs) of cancer incidence were projected for lifelong nonsmokers, using a dedicated radiation risk assessment tool and accounting for the reduced life expectancy of individuals ...
Background/Aims: Minimal hepatic encephalopathy (MHE) is common in patients with extrahepatic portal vein obstruction (EHPVO). There is no study on the treatment of MHE using lactulose in patients with EHPVO. Patients and Methods: Consecutive EHPVO patients were assessed by psychometric (number connection test (NCT-A and B), digit symbol test (DST), serial dot test (SDT), line tracing test (LTT)), and critical flicker frequency (CFF) at inclusion. Patients diagnosed as MHE were treated with lactulose and psychometric tests, CFF, and were reassessed after 3 months. Results: Of the 70 patients screened, the prevalence of abnormal psychometric test was as follows: NCT-A (41%), NCT-B (53%), DST (38%), SDT (40%), and LTT (44%). Thirty patients (43%) had two or more than two abnormal (,2 SD) psychometry tests. Lactulose improved MHE in 16/30 (53%) of patients after 3 months of treatment. Arterial ammonia decreased after lactulose treatment compared to baseline (83.7±19.1 vs. 65.1±19.3 μmol/l, ...
I get a large volume of hits from people looking up testicular cancer issues. You can read My Cancer Story, and I hope it can be of help to people. In keeping with the spirit of that post, I would like to add on some current activity.. Since my cancer in 1999, I have gone for chest x-rays and blood work once a year(and I get my PSA every year or so, too), along with a checkup from a local Hematologist/Oncologist. I also go for an abdominal CT Scan every three years. This approach will go on indefinitely. As some research suggests that the radiation treatment I received in 1999 could have some correlation to colon cancer down the road, I have also had two colonoscopies in the last several years. As the last one did not show any polyps, my gastrointestinal doctor advised on another one in ten years. My Hematologist/Oncologist has not weighed in on this yet. Needless to say, I feel very strongly that people should have regular colonoscopies, and I will go again whenever required to do so.. All of ...

The virus that causes COVID-19 is about 0.1 micrometer in diameter. (A micrometer (µm) is one one-thousandth of a millimeter.) The holes in woven cloth are visible to the naked eye and may be five to 200 micrometers in diameter. It is counter-intuitive that cloth can be useful in this setting - its been compared to putting up a chain-link fence to stop mosquitoes. However, that analogy is wrong in many ways.. According to aerosol science, whenever liquid hangs in air it is technically an aerosol, but other disciplines use the word droplet to mean a coarse particle five micrometers or larger, and reserve aerosol for fine particles smaller than five micrometers in effective diameter.. When we breathe, talk, eat, cough, sneeze or sing, we emit particles across a range of sizes, both coarse and fine, and the virus is in those particles. Even though there are gaps between the threads in cloth, the threads are usually wider than the gaps.. Also, at this microscopic level, the thread has ...
A method of fabricating a micro-electrical-mechanical system (MEMS) transducer comprises the steps of forming a membrane on a substrate, and forming a back-volume in the substrate. The step of forming a back-volume in the substrate comprises the steps of forming a first back-volume portion and a second back-volume portion, the first back-volume portion being separated from the second back-volume portion by a step in a sidewall of the back-volume. The cross-sectional area of the second back-volume portion can be made greater than the cross-sectional area of the membrane, thereby enabling the back-volume to be increased without being constrained by the cross-sectional area of the membrane. The back-volume may comprise a third back-volume portion. The third back-volume portion enables the effective diameter of the membrane to be formed more accurately.

There are many problems of both fundamental and of practical importance that require measurement of extremely low concentrations of certain impurities. Molecular Spectroscopy provides one approach that excels in the high specificity provided by the detailed structure in the spectrum, particularly for molecules in the gas phase. Lehmanns group has been working on the development of new trace sensors, largely based upon the method of cavity ring-down spectroscopy (CRDS). In CRDS, one forms a stable optical cavity using mirrors with reflectivity , 99.99% and observes absorption of a sample contained inside the cavity by an increase in the rate of decay of light that is trapped between the mirrors. Sample absorption as low as 1 part in 109 per pass of the cell can be measured in this way. The Lehmann group pioneered the use of low cost and rugged diode lasers developed for the telecom industry in CRDS and has demonstrated detection of a number of small molecules, such as H2O, NH3, and CH4 at levels ...
