Examination of the contaminants and performance of animals fed and bedded using de-inking paper sludge.

In the noncereal-producing areas, there is not enough straw to supply the amount required for animal bedding. However, pulp and paper mills produce tons of wood fiber wastes, including de-inking paper sludge (DPS), in which most toxic compounds are at their detection limit. Among the detected compounds in DPS, aluminum, copper, and polycyclic aromatic hydrocarbons (PAHs) are present and were selected as model molecules. In this context, broilers were submitted to a diet containing 0, 5, and 10% of their ration as DPS. In addition, broilers and pigs were grown on de-inking paper sludge and wood shavings beddings. The presence of aluminum and copper were evaluated in blood and bones, whereas the presence of PAHs was evaluated in fat, liver, meat, and urine or blood of broilers and pigs. Animal performances were also investigated. DPS bedding did not increase aluminum or copper contents of blood or bones or PAHs in animal tissues. Animal performances and health were similar on DPS and wood shaving beddings. Using DPS as bedding material provides an integrated source of disposal of DPS and animal manure.

Ectopic Cushing's syndrome and pulmonary carcinoid tumour identified by [111In-DTPA-D-Phe1]octreotide.

The differential diagnosis and management of Cushing's syndrome remain difficult, particularly for ectopic adrenocorticotropin (ACTH) syndromes resulting from small bronchial carcinoids. We report the case of a 41-year-old man with ectopic ACTH-dependent Cushing's syndrome. Two computed tomography scans of the thorax were normal and magnetic resonance imaging of the chest showed a 6-mm hyperintense T1-weighted area close to the left pulmonary hilus, interpreted as probably vascular by the radiologists. An [111In-DTPA-D-Phe1]octreotide scintigraphy scan demonstrated a positive image for somatostatin receptors in exactly the same location and surgery confirmed the presence of a small ACTH-secreting carcinoid tumour in the upper left lung lobe which was resected. Surgery cured the hypercorticism of the patient. The differential diagnosis of Cushing's syndrome and the procedure for localisation of an ACTH source are discussed.

Characteristics of pharmaceutical opinions written in a Quebec community pharmacy.

OBJECTIVE: To describe the characteristics of pharmaceutical opinions written in a community pharmacy and to estimate the possible effects of these opinions on patient drug profiles. DESIGN: Retrospective survey. SETTING: The community pharmacy where these opinions were written is located in a rural area of the province of Quebec. Only health-related items are sold and no merchandise is displayed in this pharmacy. PARTICIPANTS: Ten pharmacists worked at this pharmacy during the period of the study. INTERVENTION: Pharmacists were paid when they sent advice to a patient or a physician about the patient's drug profile or about the therapeutic value of a prescribed treatment. This survey included recommendations made from 1978 to 1983. A sample of 600 opinions was drawn at random from a total of 1992 opinions that had been written at the site of the study. MAIN OUTCOME MEASURE: The impact of each opinion was assessed by analyzing patient drug profiles for three months after the opinion was written to determine if the recipient had followed the pharmacist's recommendation. RESULTS: Pharmacists, on their own initiative, sent 97.9 percent of the opinions. Only 1.7 percent of the opinions were requested by patients and 0.4 percent by physicians. Most opinions were addressed to patients (86.7 percent) rather than to physicians (13.3 percent). Almost four of five recommendations sent to patients were about compliance (45.1 percent) or were suggestions for improving the therapeutic effect of a medication or replacing a drug with nondrug treatment (33.4 percent). The three most common recommendations sent to prescribers were to replace one drug with another (25 percent), to change the dose or dosing schedule of a drug (16.3 percent), and to discontinue drug treatment (16.3 percent). Chemical stability, underuse or overuse of a medication, and adverse effects were the most frequent causes of recommendations sent to patients. Adverse effects, interactions, and the underuse of a medication were the most frequent reasons for recommendations sent to physicians. The proportion of recommendations that were implemented was 77.7 percent for patients and 58.1 percent for physicians. CONCLUSIONS: The pharmaceutical opinion seemed to be a good means of communicating with patients and prescribers on a wide variety of problems encountered in a community pharmacy. It allowed pharmacists to be paid for their expertise even if a drug was not dispensed. Also, the pharmaceutical opinion could compensate for the loss of income when the pharmacist recommended replacing a prescribed medicine with nondrug treatment.

Hepatitis B surface antigen: regional variation in sub-type ratio in the Canadian Red Cross donor population.

A total of 344 sera positive for hepatitis B surface antigen from volunteer blood donors at several Canadian Red Cross centres were subtyped for ad and ay specificity by counterelectrophoresis. Of the 50 sera from Toronto 21 (42%) were ad and 29 (58%) were ay; of the 95 from Montreal 82 (86%) were ad and 13 (14%) were ay; of the 199 from Quebec 179 (90%) were ad and only 20 (10%) were ay. The w and r specificities were also determined in 125 of the samples: 123 were w; the 2 samples of r specificity were from Toronto. On the other hand, among 45 sera from patients with acute hepatitis type B in Quebec 13 (29%) were ad and 33 (71%) ay.
