Eventration of the diaphragm is an abnormal elevation of the dome of diaphragm. It is a condition in which all or part of the diaphragm is largely composed of fibrous tissue with only a few or no interspersed muscle fibers. It can be complete or partial. Complete eventration of the right diaphragm, as seen in this adult patient, is relatively rare.
We describe an adult patient with a primary left atrial leiomyosarcoma in whom live/real time three-dimensional transthoracic echocardiography showed echolucent areas within the mass consistent with necrosis or hemorrhage surrounded by dense band-like echo densities indicative of fibrosis or collagen giving a "doughnut" like appearance. These findings were consistent with histopathology, which showed areas of necrosis and dilated vascular channels within the fibrotic tumor. Our case further illustrates the usefulness of three-dimensional transthoracic echocardiography in characterizing the morphologic features of an intracardiac mass.
Background
Regional variation in Helicobacter pylori resistance patterns is a significant contributing factor for the ineffectiveness of traditional treatments. To improve treatment outcomes, we sought to create an individualized, susceptibility‐driven therapeutic approach among our patient population, which is one of the poorest in the nation. It is medically underserved, minority‐predominant and has high incidence of H pylori infection.
Methods
We compiled various factors involved in the antibiotic resistance of H pylori from literature. We then created a predictive model to customize therapies based on analyzed data from 2,014 H pylori patients with respect to several of these factors. The predictions of the model were further tested with analysis of patient stool samples.
Results
A clear pattern of H pylori prevalence and antibiotic resistance was observed in our patients. We observed that majority of H pylori patients were women (62%) and over the age of 40 years (80%). 30% and 36% of the H pylori patients were African American and Hispanic, respectively. A median household income of less than $54,000, past H pylori infection, previous use of certain antibiotics for any infection decreased the chance of eradication. Results of the stool testing were consistent with model predictions (90% accuracy).
Conclusion
This model demonstrates the predictive accuracy of H pylori infection and antibiotic resistance based on patient attributes and previous treatment history. It will be useful to formulate customized treatments with predicted outcomes to minimize failures. Our community attributes may contribute toward broad applicability of model for other similar communities.
We investigated the effects of i.v. adenosine on coronary blood flow in 10 normal subjects undergoing investigation for chest pain. Coronary flow transiently doubled after > 3.5 mg adenosine without increase in perfusion pressure, systolic load or inotropic state at a constant, paced heart rate. The data provide direct evidence that adenosine dilates coronary arteries in man. The transience of the effect suggests a possible role for adenosine in repeated estimations of coronary flow reserve.
To compare the fluoride release from Conventional Glass Ionomer Cement (GIC), Resin Modified GIC (RMGIC), and Cention N Alkasite Material. Material and Methods: Forty-five disc-shaped specimens of three different restorative materials (Conventional GIC, RMGIC, and Alkasite material) were made and divided into 3 groups (n=15). Fluoride release was evaluated at the end of Day 1, 7, 14, and Day 28 using fluoride ion-selective electrode. Intergroup and Intra-group analysis was done using One-way ANOVA with a Post-hoc test. A p-value of <0.05 was considered statistically significant. Results: Cention showed more fluoride release (in parts per million) than GIC and RMGIC at increased time duration. However, at the end of day 1, there was lesser fluoride release with Cention, as compared with the other groups. Conclusion: The new Alkasite restorative material showed promising results in terms of fluoride release and is better than GIC and RMGIC at increased time duration.
Although fibromatosis of the mesentery is a very rare locally aggressive benign condition, the uncertain treatment modalities, the natural history of the disease, and the other common differential diagnosis of the condition along with inexperience of the general clinicians with this disease pose a challenge to the professionals. The prolonged periods of stability and even regression in size of the tumor offer a hope for treatment. Accounting for 0.03 % of all neoplasms, it is also known as deep fibromatosis and desmoid tumor. Here, we discuss one case of primary mesenteric fibromatosis in a young male patient who presented to us with chronic abdominal pain after he was treated for acid peptic disease for the same at a local hospital. This case shows how management of this disease can be delayed due to unfamiliarity among clinicians of this condition. In our patient, a palliative surgical management plan was undertaken due to symptomatic mass in the abdomen, owing to unresectability.
Diabetic ketoacidosis is one of the most serious complications of diabetes mellitus. Role of bicarbonate therapy in severe diabetic ketoacidosis is controversial. There are only few case reports of management of refractory diabetic ketoacidosis with renal replacement therapy. Here, we present a case of young male with severe diabetic ketoacidosis, which was refractory to fluid resuscitation, insulin and was managed successfully managed with peritoneal dialysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
