ABSTRACT
BACKGROUND: Difference of the clinical characteristics and outcome of acute appendicitis (AA) between young old (age 60 to 79 years) and octogenarian patients (age 80) is unknown. We hypothesized that octogenarian patients would have more atypical presentation and worse outcomes. METHODS: Our study was a 10-year retrospective analysis of a hospital based database. All patients with histopathologically confirmed AA from 1995 to 2005 registered in this database were selected for study. Demographic data, preexisting conditions, clinical manifestations, Alvarado score, delay in surgery, complications, and mortality were compared between the octogenarians and young old. Independent effect of age on outcomes was examined by logistic regression model controlling for sex, comorbidities, and time delayed for surgery. RESULTS: Octogenarian patients constituted 93 (14.8%) of 628 geriatric patients with AA. On clinical manifestations, migrating pain and localized iliac fossa tenderness were less common in the octogenarians. Low sensitivity of Alvarado score in diagnosing AA was noted in both young old (50.7%) and octogenarian (44.1%) patients. Compared with young old patients, octogenarians had a longer delay in surgery and worse outcomes. Octogenarians had a significantly higher perforation rate (65.6% vs 49.5%, P < 0.001), postoperative morbidity rate (18.3% vs 10.1%, P < 0.001), and mortality rate (6.5 % vs 1.5 %, P < 0.001). Octogenarian age was independently associated with appendiceal perforation (OR, 95% CI; 1.94, 1.23 approximately 3.08), postoperative morbidity (2.0, 1.10 approximately 3.62), and mortality (4.5, 1.54 approximately 13.41). CONCLUSIONS: The clinical presentation of AA in octogenarian patients is atypical and the outcomes are worse than young old patients.

BACKGROUND: The aim of this study was to identify factors associated with rupture in elderly patients with acute appendicitis. METHODS: The medical records of 601 consecutive patients >60 years of age with acute appendicitis between 1995 and 2005 were retrospectively reviewed. Historical, clinical and laboratory factors in patients with both intact and ruptured appendices were examined with univariate and multivariate analyses by logistic regressions. RESULTS: Nine factors predicted appendiceal rupture age (odds ratio (OR) 1.05, confidence interval (CI) 1.02-1.07), male sex (OR 1.96, CI 1.35-2.06), preadmission duration of pain (OR 1.23, CI 1.11-1.36), interval of time from admission to surgery (OR 1.02, CI 1.01-1.04), fever >38 degrees C (OR 2.59, CI 1.78-3.77), left shift in leucocyte count >76% (OR 2.34, CI 1.27-4.32), anorexia (OR 2.03, CI 1.38-2.99) and a retrocaecally positioned appendix (OR 1.93, CI 1.15-3.24). CONCLUSION: The incidence of appendiceal rupture, or complications secondary to appendiceal rupture, in elderly patients may be decreased if surgery is expedited when the temperature is >38 degrees C or there is a left shift in leucocyte count >76%, especially in men with anorexia.

Metaldehyde, a cyclic tetramer of acetaldehyde, is a widely used molluscicide. Although cases with acute metaldehyde poisoning have been reported, the occurrence of severe poisoning is uncommon. To provide more information on human metaldehyde poisoning, we reviewed 15 cases of metaldehyde exposure reported to the Taiwan National Poison Control Center at the Taipei Veterans General Hospital between 1991 and 2002. While 7 patients were asymptomatic, the other 8 patients, including 4 who coingested alcohol or other poisons, exhibited toxic manifestations of abdominal pain, dizziness, nausea, irritation of oral mucosa, and seizures after oral exposure. One patient died after ingesting 12 g (or 258.6 mg/kg) of metaldehyde. Although the toxicity from metaldehyde is largely mild, the clinical course of metaldehyde poisoning may be rapidly deteriorating and fatal on rare occasions. Physicians should therefore be cautious in managing patients with metaldehyde poisoning, and vigorous supportive measures should be promptly instituted in patients who manifest severe toxicity.
