Synchronous MALT lymphoma of the colon and stomach and regression after eradication of and .

Mucosa-associated lymphoid tissue (MALT) is vital for host immunological surveillance against pathogens. MALT lymphoma, also known as extranodal marginal zone B cell lymphoma, is a non-Hodgkin's lymphoma subtype that predominantly arises in the gastrointestinal tract. Chronic infection is a common cause of gastric MALT lymphoma, although other infections are reported in association with extragastric MALT lymphomas.

A Case-Control Study of the Association between Vitamin D Levels and Gastric Incomplete Intestinal Metaplasia.

: Low circulating vitamin D levels are associated with gastric adenocarcinoma, but whether vitamin D levels are associated with premalignant gastric mucosal changes is unknown. Here, we determined associations between vitamin D levels and gastric incomplete intestinal metaplasia, a known gastric adenocarcinoma risk factor. : This was a retrospective, unmatched, case-control study comparing serum 25-hydroxyvitamin D levels among subjects with gastric incomplete intestinal metaplasia (cases; = 103) and those without gastric incomplete intestinal metaplasia (controls; = 216).

CD3-positive plasmablastic B-cell neoplasms: a diagnostic pitfall.

Rare B-cell neoplasms with plasmablastic differentiation may aberrantly express CD3 by immunohistochemical staining, which places a great challenge for diagnosis. We here studied 17 cases of CD3+ plasmablastic B-cell neoplasms, including 12 plasmablastic lymphomas and 5 plasmablastic plasma cell myelomas. All 17 cases occurred in the extranodal sites with a male predominance (13/17).

Clinical and epidemiological characteristics of patients with acute drug intoxication admitted to ICU.

: Drug overdose continues to be the most common cause of acute poisoning worldwide. There has been a substantial increase in drug overdose incidence and prevalence over the past decade, probably as a result of the emergence of new synthetic designer drugs. The purpose of this study is to describe the clinical and epidemiological characteristics of patients with acute drug intoxication admitted to the Intensive Care Unit (ICU).

A rare case of thrombotic microangiopathy triggered by acute pancreatitis.

Thrombotic microangiopathy (TMA) occurring after acute pancreatitis is rarely described. Without prompt intervention, TMA can be, and often is, lethal, so prompt recognition is important. Here, we present a case of a 61-year-old woman with a history of alcohol misuse who presented with epigastric pain, nausea and vomiting after binge drinking.

Effects of time and day of admission on the outcome of critically ill patients admitted to ICU.

Background: Studies have shown that patients admitted to hospitals on weekends and after-hours experience worse outcome than those admitted on weekdays and daytime hours. Although admissions of patients to intensive care units (ICUs) occur 24 hours a day, not all critical care units maintain the same level of staffing during nighttime, weekends, and holidays. This raises concerns in view of evidence showing that the organizational structure of an ICU influences the outcome of critically ill patients.

Prolonged cardiac arrest complicating a massive ST-segment elevation myocardial infarction associated with marijuana consumption.

Recreational substance use and misuse constitute a major public health issue. The annual rate of recreational drug overdose-related deaths is increasing exponentially, making unintentional overdose as the leading cause of injury-related deaths in the United States. Marijuana is the most widely used recreational illicit drug, with approximately 200 million users worldwide.

Disseminated Cryptococcal Infection Resulting in Acute Respiratory Distress Syndrome (ARDS) as the Initial Clinical Presentation of AIDS.

Cryptococcosis is a cosmopolitan but rare opportunistic mycosis which is usually caused by Cryptococcus neoformans. Although the most common and worrisome disease manifestation is meningoencephalitis, pulmonary cryptococcosis has the potential to be lethal. The diagnosis of cryptococcal pneumonia is challenging, given its non-specific clinical and radiographic features.

Can urinary nitrites or other urinalysis findings be a predictor of bacterial resistance of uncomplicated urinary tract infections?

Background And Objectives: To evaluate whether initial urinalysis (UA) and urinary nitrite results can be used as a proxy for choosing empiric antibiotic therapy.

Materials And Methods: A retrospective study was conducted in an urban inner city community hospital in New York City (NYU Woodhull Medical Center). We reviewed the charts of patients seen in the Emergency Department and Pediatric Clinic who had a diagnosis of urinary tract infection (UTI) during a 3 year time period (January 2010-December 2012).

The Wide and Unpredictable Scope of Synthetic Cannabinoids Toxicity.

Drug use and abuse continue to be a large public health concern worldwide. Over the past decade, novel or atypical drugs have emerged and become increasingly popular. In the recent past, compounds similar to tetrahydrocannabinoid (THC), the active ingredient of marijuana, have been synthetically produced and offered commercially as legal substances.

Assessing the utility of ICU admission for octogenarians.

Background: Advanced age is associated with increased severity of acute critical illnesses and admission to ICU. Despite advances in the support for older critically ill patients, the short- and long-term mortality rates remain substantial. The purpose of this study is to analyze the factors influencing the outcome of a geriatric population admitted to the ICU.

Cepacia Syndrome in a Non-Cystic Fibrosis Patient.

Burkholderia (formerly Pseudomonas) cepacia complex is a known serious threat to patients with cystic fibrosis, in whom it has the potential to cause the fatal combination of necrotizing pneumonia, worsening respiratory failure, and bacteremia, known as Cepacia syndrome. The potential for this pathogen to infect non-cystic fibrosis patients is limited and its epidemiology is poorly understood. Previously reported cases of severe Burkholderia cepacia complex lung infection in immunocompetent hosts include pneumonia, bronchiectasis, pyopneumothorax, and cavitary lesions.

Pulmonary Thromboembolism Complicating Amebic Liver Abscess: First Reported Case in the United States-Case Report and Literature Review.

Even in the absence of Amebic colitis, Amebic liver abscess (ALA) is the most common extraintestinal complication of Entamoeba histolytica infection. In the USA, it is most prevalent in middle aged immigrant males from endemic countries such as Africa, Mexico, and India. One of the complications of ALA is inferior vena cava (IVC) thrombosis, which is believed to result from the mechanical compression of the IVC and the consequent thrombogenic nidus elicited from the resultant inflammatory response.

Positive attitude toward life, emotional expression, self-rated health, and depressive symptoms among centenarians and near-centenarians.

Objectives: Favorable attitudes, emotions, personality characteristics, and self-rated health have been associated with successful aging in late life. However, less is known regarding these constructs and their relationships to mental health outcomes in the oldest old persons. This study examined cross-sectional relationships of these psychological factors to depressive symptoms in centenarians and near-centenarians.

Visceral Kaposi's Sarcoma Presenting as Upper Gastrointestinal Bleeding.

Since the advent of highly active antiretroviral therapy (HAART), the incidence of acquired immunodeficiency syndrome- (AIDS-) related Kaposi's sarcoma (KS) has decreased dramatically. While cutaneous KS is the most common and well-known manifestation, knowledge of alternative sites such as the gastrointestinal (GI) tract is important. GI-KS is particularly dangerous because of its potential for serious complications including perforation, obstruction, or bleeding.

Short implants: are they a viable option in implant dentistry?

Short-length implants (<10 mm) can be used effectively in atrophic maxillae or mandibles even with crown/implant ratios that previously would have been considered excessive. Short implants can support either single or multiple units and can be used for fixed prostheses or overdentures. The use of short-length implants may avoid the need for complicated bone augmentation procedures, thus allowing patients who were either unwilling or unable for financial or medical reasons to undergo these advanced grafting techniques to be adequately treated.

Massive cerebral edema resulting in brain death as a complication of Cryptococcus neoformans meningitis.

Despite the widespread use of highly active antiretroviral therapy, cryptococcal meningoencephalitis has emerged as the second leading cause of infectious morbidity and mortality in HIV-infected patients worldwide. It presents usually as subacute or chronic disease but occasionally may be fulminant. Common clinical presentations included headache, fever, and depressed level of consciousness.

Polymicrobial Bacteremia Involving Comamonas testosteroni.

Comamonas spp. are uncommon isolates in microbiology laboratories and have been rarely observed as an infectious agent in clinical practice. They have widespread environmental distribution and have been isolated from water, soil, and plants as well as from some hospital devices such as intravenous catheters and water contained in humidifier reservoirs used in respiratory treatment.

Prognostic factors associated with adverse outcome among critically ill elderly patients admitted to the intensive care unit.

Introduction: Despite concerns over the appropriateness and quality of care provided in the intensive care unit (ICU) at the end of life, the number of elderly patients who receive critical care is increasing. Despite this, many physicians have doubts as to whether elderly patients are good candidates for ICU care because of the apparently poor outcome during and after critical care in this population. The objective of the present study was to describe the clinical characteristics and outcome of a geriatric population admitted to the ICU.
