Olive pulp and its effluents suitability for soil amendment.

Olive pulp (OP) and its effluents produced after digestion processes were characterised and their suitability as soil amendment materials were investigated. Results showed that OP and its effluent for hydrogen (EH2) and methane production (ECH4) contain high amount of organic matter, remarkable concentration of nutrients and negligible content of heavy metals. Decreasing concentrations of low molecular weight phenols (monomeric phenols) and increasing amount of humic-like materials were found passing from OP to EH2 and ECH4. The effects on both wheat seed germination and seedlings growth were also investigated. Addition of OP at the highest doses delayed both seed germination and seedling growth. These effects decreased when the OP and its effluents were incorporated into the soil. On the contrary an enhancement of seedlings growth was detected by addition of EH2 and ECH4. Enhancement effects also were found out by addition of lower OP concentrations. The phytotoxic effects decreased when the products were incorporated into the soil.

Nasopharyngeal carcinoma: clinical assessment and review of 176 cases.

OBJECTIVE: The objective of this study was to delineate salient disease characteristics and to determine factors associated with survival in a series of patients with nasopharyngeal carcinoma (NPC). STUDY DESIGN: To address our research objective, we used a retrospective cohort study design and a sample of patients who presented for evaluation and management of NPC. Demographic data, medical history, radiographic findings, staging, and histology were recorded. Treatment and follow-up information were ascertained. Survival data and descriptive statistics were calculated. Multivariate analyses identified risk factors associated with survival rates for all World Health Organization (WHO) types. RESULTS: The sample comprised 123 men and 53 women (n = 176) of which 70% were white and 23% were Asian. A neck mass was the initial symptom in 49% of patients. In 99% of cases, radiation therapy was the primary treatment mode. WHO types 1 and 3 were most common. Overall 5-year disease-free survival rate was 45.5%. Age, use of tobacco or ethanol, and number of presenting symptoms were statistically associated with decreased survival rate in WHO 1 (squamous cell) tumors. Male gender and total number of presenting symptoms were associated with decreased survival rate for WHO 2 and 3 (nonkeratinizing or undifferentiated) tumors. CONCLUSIONS: Being attuned to the presenting signs of NPC may lead to a more expedient diagnosis. The differing risk factors associated with WHO 1 tumors become clear in this predominantly white population.

Epidemiology of acute diarrhea in children living in Sicily.

A longitudinal survey (February 1984 - January 1985) on the incidence of acute diarrhea episodes in a sample of 8,164 children (aged 0-12 years) living in southeastern Sicily was carried out by means of weekly telephone interviews with doctors practising in the territory. The incidence rate was 0.479 (0.472-0.485 95% C.I.) per child per year and the frequency of episodes was significantly higher (p less than 0.001) in children aged 0-4 years (0.86). Diarrhea was more frequent in industrial areas than in rural ones, and almost half (45.1%) of the total episodes had a mild course. No death from diarrhea occurred and admission to hospital was reported for 8.4% of all cases.
