ABSTRACT Objective: To assess the severity caused by button batteries in esophagus. Methods: A total of 32 patients admitted with ingesting button batteries were retrospectively evaluated. Chest X-ray was ordered for diagnosis. Hospital stays, interventions, complications and mortality of the patients were collected. The time between the patients ingested the buton battery and its removal was defined as its duration in esophagus. All the patients underwent rigid esophagoscopy under general anaesthesia. Buton batteries at the first narrowing were removed by magyl clamp. Results: Of 32 patients, 21 were females, with a mean age of 22 months. The mean duration of ingestion was 17 hours. The mean hospital stay was 10 days. Of the patients, 75% were admitted within 24 hours. Complication rate was 19% and mortality rate was 6%. There was a strong correlation among the number of the cases and the coming years (p < 0.001). The regression was between the number of cases per year (outcome variable) and the years of the study (explanatory variable), (p< 0.001, R = 0.644, Figure 3). There was a significant finding that more cases (90%) were admitted in the last 12 years compared with the number in first 12 years (p < 0.001). There were no complications in cases in which the button battery was impacted in esophagus for less than 24 hours; however, eight cases whose duration was more than 24 hours resulted in complications in six patients and fatality in two patients (p < 0.001). Conclusion: Batteries should be removed upon its diagnosis. Otherwise, the injury in the esophageal mucosa may be caused by delay and can cause an increase in morbidity and mortality.

This study was conducted to determine the effects of spraying oregano essential oil (OEO) onto sugar beet pulp silage (SBPS) on silage quality and aerobic stability after opening. A factorial experiment with three replicates of three treatments and four time periods was conducted using laboratory-type plastic silos. The treatments were an untreated control, silage sprayed with 10 ml/75 cm² OEO, and silage sprayed with 20 ml/75 cm² OEO. The silages were sampled at 0, 72, 120, and 168 hours after spraying. Temperature, L*, a*, and b* colour values, pH, water-soluble carbohydrates, crude nutrient contents, Fleig score, metabolizable energy (ME) value, lactic acid bacteria (LAB), total live bacteria (TLB), yeast, and mould formation were assessed. Spraying OEO onto SBPS did not affect L*, a*, and b* values, pH, water-soluble carbohydrates, and Fleig score values, but decreased temperature. Spraying OEO onto the silage increased organic matter, ether extract, acid detergent fibre, neutral detergent fibre and acid detergent lignin contents without affecting crude protein, crude fibre, nitrogen free extract, and ME contents. Irrespective of treatment, crude protein, ether extract, acid detergent fibre, acid detergent lignin, nitrogen free extract, Fleig score, and ME contents of silages increased with time after spraying. The OEO spraying reduced LAB, TLB, and yeast contents in silages. In conclusion, OEO spraying onto opened SBPS reduced LAB, TLB, and yeast formation and stopped mould growth up to 72 hours without affecting their nutritional properties, suggesting that OEO could be used to ensure the stability of SBPS.

ABSTRACT Lead (Pb) is a heavy metal, which adversely affects thyroid gland function and structure. Due to its high molecular weight and abundant functional groups, humic acid substances (HAS) can form chelates with heavy metals. The experiment was conducted to evaluate the prophylactic effect of HAS on thyroid hormone levels and histopathological lesions of laying hens exposed to lead (Pb) poisoning. After a week of adaptation, 192 Lohmann White laying hens (25 weeks of age) were fed one of four diets: a basal diet (BD) or the BD with HAS (0.15%), with Pb (0.3 g/kg), or with both. Experimental groups were replicated in 12 cages, with four hens each. Pb poisoning did not alter triiodothyronine (FT3; 3.22 ± 0.20 ng/dL) or thyroxine (FT4; 0.71 ± 0.08 ng/dL) concentrations, but caused a 167% increase in thyroid stimulating hormone (TSH) concentration. HAS supplementation returned the high TSH levels of hens exposed to Pb poisoning to normal values. Degenerative changes in the epithelial cells of the thyroid gland of the hens exposed to Pb poisoning were evidenced. Connective tissue cells in the interfollicular area and total amount of colloids with partially atrophic follicles were observed. These histopathological findings were less severe when HAS was added to the diet. In conclusion, HAS alleviates the effects of Pb poisoning on thyroid gland function and structure, possibly preventing its internalization by the tissue by forming chelates and exerting anti-inflammatory effects.
