General characteristics of hospitalized patients after deliberate self-poisoning and risk factors for intensive care admission.

BACKGROUND: Deliberate self-poisoning (DSP) is recognized as a major health problem worldwide with significant morbidity. After DSP, a substantial number of patients require intensive care unit (ICU) care, but little is known about how these patients differ from patients admitted to a general medical ward. METHODS: From January 2001 to December 2002, all adult patients admitted to Soroka University Hospital after DSP were identified by ICD-9 coded diagnoses. Demographic data, previous psychiatric illness, laboratory tests, medication used in the DSP, presenting syndromes, treatment, and time elapsed after ingestion until emergency department presentation were obtained retrospectively from the patients' charts. RESULTS: Out of a total of 217 patients, 34 (15.7%) were admitted to the ICU. Their mean age was 35.9 years and 65.4% of the patients were female. In multivariate analysis, the risk factors for ICU admission were suicide attempt with an antihypertensive medication (OR=12.2, 95% CI 2.3-65.8), coma on presentation (OR=15.8, 95% CI 4.9-50.7), and arrival at the emergency department less than 2 h after ingestion as compared to arrival after 2 h (OR=8.4, 95% CI 2.6-26.7). Previous psychiatric disease had no impact on ICU admission, and a recurrent attempt was protective of ICU admission. CONCLUSIONS: We have shown that ingestion of antihypertensive medication, coma upon presentation, and emergency department admission less than 2 h after ingestion are predictive of ICU admission after a deliberate overdose with medication. These variables may help emergency department physicians to identify high-risk patients more quickly and, thereby, to improve patient care.

Colitis cystica profunda and solitary rectal ulcer syndrome-polypoid variant: Two confusing clinical conditions.

Colitis cystica profunda and solitary rectal ulcer syndrome-polyoid variant are related chronic benign disorders with characteristic histological features. However, the clinical and endoscopic settings are confusing and misleading, suggesting other rectal conditions. We report a case of colitis cystica profunda and solitary rectal ulcer syndrome-polypoid variant that was misdiagnosed initially as an ulcerative proctitis. Since an occult malignancy could not be ruled out by superficial biopsies, the mass was removed by full-thickness transanal excision.

Nasopharyngeal versus oropharyngeal sampling for isolation of potential respiratory pathogens in adults.

The optimal methodology for the identification of colonization by potential respiratory pathogens (PRP) in adults is not well established. The objectives of the present study were to compare the sensitivities of sampling the nasopharynx and the oropharynx for identification of PRP colonization and to compare the sensitivities of samples from the nasopharynx by swab and by washing for the same purpose. The study included 500 participants with a mean age of 65.1 +/- 17.8 years. Of these, 300 patients were hospitalized for acute febrile lower respiratory tract infection and 200 were controls. Each participant was sampled by oropharyngeal swab (OPS), nasopharyngeal swab (NPS), and nasopharyngeal washing (NPW). The samples were tested by conventional bacteriological methods to identify Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. OPS detected colonization by S. pneumoniae in 30% of the subjects compared with 89% by NPS and NPW (P < 0.000001). The corresponding rates for H. influenzae were 49% and 64%, respectively (no significant difference [NS]), and for M. catarrhalis were 72% and 46%, respectively (P < 0.0004). NPS identified 61% of the cases of colonization with S. pneumoniae, compared with 76% by NPW (NS). The corresponding rates for H. influenzae were 31% and 56%, respectively (P < 0.04), and for M. catarrhalis were 39% and 33%, respectively (NS). We conclude that the sensitivities of nasopharyngeal and oropharyngeal sampling for identification of PRP colonization in adults are different for each of the three bacteria in this category. The combined results of sampling from both sites are necessary to obtain a true picture of the rate of colonization. NPW is superior to NPS.

Primary aortoduodenal fistula: Pitfalls and success in the endoscopic diagnosis.

Primary aortoenteric fistula is a rare but catastrophic cause of gastrointestinal bleeding. The diagnosis of primary aortoenteric fistula is difficult to make and is usually accompanied by a very high level of clinical suspicion. It should be considered in any elderly patient presenting with upper gastrointestinal bleeding in the context of a known abdominal aortic aneurysm. Prompt surgical intervention is necessary. We present the case of a 78-year-old man with a history of atherosclerotic abdominal aortic aneurysm which is presented with massive upper gastrointestinal bleeding due to a primary aortoduodenal fistula. Initial misdiagnosis led to a delay in treatment and the patient succumbed to the illness.

Deliberate self-poisoning with acetaminophen: a comparison with other medications.

BACKGROUND: Acetaminophen is the most common drug employed in deliberate self-poisoning (DSP) in many countries and can lead to acute liver failure. The purpose of the present study was to compare DSP with acetaminophen with DSP with other medications. METHODS: From January 2001 to December 2002, all patients admitted after DSP to Soroka University Hospital in Beer-Sheva, Israel, were identified. Demographic data and medical history were obtained retrospectively. RESULTS: There were 282 incidences of DSP in the study period. The mean age of 94 patients with an acetaminophen overdose was lower than that of patients who had attempted DSP with other medications (24.8 vs. 34.6 years, p<0.001). There was no gender or ethnic difference between the groups. Patients with DSP with acetaminophen were less likely to make recurrent attempts (23.4% vs. 39.9% p=0.006), less likely to have psychiatric disorders (32% vs. 59% p<0.001), and had a shorter hospital stay (1.7 vs. 2.1 days, p=0.05). The acetaminophen group had less of an impairment in level of consciousness (84% vs. 52.1% p<0.001) and had less need for ICU care (6.4% vs. 14.9%, p=0.04). Serum levels were checked in 68 (72.3%) of the patients in the acetaminophen group and they were found to be high in 6 (8.8%) of them (95% CI 2.1-15.5%). CONCLUSION: Taking an overdose of acetaminophen is a common method of DSP, with patients tending to have a more benign presentation and shorter hospital stay than those who attempt DSP with other medications. Further research on the optimal care of these patients and multi-disciplinary approaches to DSP prevention are needed.

[Endovascular stent-graft repair of aorto-esophageal fistula causing upper gastrointestinal bleeding].

An 83 year old woman with massive upper GIT bleeding was diagnosed as having an aorto-esophageal fistula in the mid descending thoracic aorta which was mildly aneurysmatic and showed atheromatous changes. Past medical history reported Giant Cell Arteritis. Following endoscopy and evaluation using CT angiography, the patient underwent an endovascular stent graft repair of the thoracic aorta using a Talent stent graft. Recovery was uneventful and the patient recuperated. This case study discusses a possible common baseline pathology of the thoracic aortic aneurysm, the aorto-esophageal fistula and the Giant Cell Arteritis.

The epidemiology of primary biliary cirrhosis in southern Israel.

BACKGROUND: The epidemiology of primary biliary cirrhosis has changed significantly over the last decade, with a trend towards increasing prevalence in many places around the world. OBJECTIVES: To determine the overall prevalence of PBC in southern Israel and the specific rates for different immigrant groups between January 1993 and October 2004. METHODS: Multiple case-finding methods were used to identify all cases of PBC in the study region. Age-adjusted prevalence rates were compared among the different immigrant groups. RESULTS: A total of 47 cases of PBC were identified with an overall prevalence of 55 cases per million. All patients were women, and all except for a Bedouin Arab were Jewish. Foreign-born patients comprised 70% of our PBC cohort even though they represent only 45.4% of the regional population. This predominance of immigrants did not change when the rates were adjusted for age (P < 0.001). The prevalence rates were 40, 177, and 58 cases per million for those born in Israel, North Africa or Asia, and Eastern Europe, respectively. The age-specific prevalence rate for women older than 40 years varied from 135 cases per million among those born in Israel to 450 among immigrants from Eastern Europe and the former USSR to 700 cases per million among immigrants from North Africa and Asia. CONCLUSIONS: The prevalence of PBC in southern Israel is similar to that reported from some European countries. The rate is much higher among Jews than Arabs and among immigrants to Israel compared to native Israelis.

Diffuse large B-cell lymphoma with anaplastic features and focal low-grade mucosa-associated lymphoid tissue lymphoma component of the stomach.

We describe an 83-year-old man diagnosed as having diffuse, large B-cell lymphoma with anaplastic features and CD30 expression of the stomach. Focally, the tumor showed typical low-grade mucosa-associated lymphoid tissue lymphoma. We are not aware of a previous report on the transformation of low-grade gastric lymphoma of mucosa-associated lymphoid tissue type into an "anaplastic," large B-cell tumor.

Microscopic colitis.

Microscopic colitis is an idiopathic chronic inflammatory bowel disease presenting with watery diarrhea. While colonoscopy and radiology findings are normal, the colon shows striking pathologic findings, including lymphocytic colitis and collagenous colitis. The clinical course is usually benign with sustained remission. Recent medical evidence shows that bismuth and budesonide are effective treatments.
