Bevezetés: A limfómák a gasztrointesztinális traktus ritka daganatai közé tartoznak. Az úgynevezett Burkitt-like limfóma a non-Hodgkin-limfómák közé tartozó igen agresszív, gyorsan növekvő, de potenciálisan gyógyítható daganat. A sebész leginkább bélelzáródás, perforáció vagy hasi fájdalmat okozó gyorsan növekvő terime képében találkozhat vele. Tanulmányunk célja, hogy bemutassunk egy olyan esetet, amikor Burkitt-like limfóma bélelzáródás vagy perforáció nélkül okozott akut hasi panaszokat, továbbá hogy áttekintsük és összefoglaljuk a témában fellelhető tényanyagot. Esetünkkel kapcsolatban elmondhatjuk, hogy a diagnózis felállításához és a kezelés mielőbbi megkezdéséhez elengedhetetlen a szövettani mintavétel és a betegség multidiszciplináris megközelítése.

The objective of this study was to determine some metabolic and other factors predicting the risk of postpartum uterine disease (PUD), and the effects of puerperal metritis (PM) on metabolic status, reproduction and milk yield were analysed. A total of 105 Holstein-Friesian cows were included, and sampled on day < −14 prepartum and days 4, 10–14, 28–35 and 56–63 postpartum for metabolic tests. From day 4 the development of PUD, and from days 28–35 the ovarian activity was monitored. When grade ≥ 1 + ketonuria was present on day 4 postpartum, this indicated a higher probability of PUD [odds ratio (OR) 2.64; P < 0.05] including PM occurring on days 10–14 (OR: 2.65; P < 0.05). Plasma nonesterified fatty acid (NEFA) concentrations > 0.200 mmol/l on days < −14 prepartum indicated a higher risk of uterine diseases (OR: 3.44; P < 0.05). The odds of PUD increased, depending on whether a body condition score (BCS) loss of ≥ 1.0 occurred between days < −14 and 28–35 (OR: 2.82; P < 0.05), between days < −14 and 10–14 (OR: 4.79; P < 0.01) or between days 10–14 and 28–35 (OR: 10.81; P < 0.01). PM was more probable (OR: 27.3; P < 0.001) in cows with retained placenta. The risk of uterine diseases was lower in multiparous than in primiparous cows (OR: 0.29; P < 0.01). PM increased the risk of ovarian inactivity between days 28 and 35 (OR: 2.83; P < 0.05). Cows affected with PM (PM+ cows) showed lower milk production on day 4 (kg; P < 0.05) and lower milk production (P < 0.05), milk fat and milk protein production (kg; P < 0.01; P < 0.01) in the first 100 days of lactation than did PM− cows.

Abstract

This study investigates the effect of 2% lactic acid and 2% ascorbic acid mixture on the quality parameters of red deer meat and beef. After treatment samples were stored at 4 ± 1 °C. The following meat quality parameters were evaluated: pH, color, and microbiological count on days 1, 7, 14, and 21. The results showed that at the end of the experiment, the pH of the treated samples was slightly higher than the non-treated samples, indicating that the lactic acid and ascorbic acid mixture had a mild acidifying effect on the meat. The color of the treated and non-treated samples did not show any significant difference. However, the microbiological count in the treated samples was lower than the non-treated samples. These findings suggest that an acid mixture could be used as a natural preservative to enhance the microbial safety of red deer meat and beef.

Abstract

Three electrosurgical tissue-sealing devices (EnSeal ETSDRC-01, LigaSure LS1500 and Thunderbeat TB-0535PC) were compared regarding sealing time (ST), maximum working temperature (WTmax) and the total (MTZtotal) as well as the collateral microscopic thermal injury zone (MTZcollat) using laparoscopic handpieces 5 mm in diameter on four types of tissue (liver, mesentery, cross striated muscle and spleen) in an in vivo porcine model. LigaSure had the lowest mean ST in spleen, mesentery, muscle and liver, followed by Thunderbeat and EnSeal with significant differences between all types of tissues and devices. The significantly lowest mean WTmax was obtained for EnSeal in mesentery, muscle and liver. LigaSure and EnSeal operated at the lowest temperature in spleen without a significant difference between them. Thunderbeat produced significantly higher temperature peaks in all cases. The lowest mean MTZtotal was caused by LigaSure and EnSeal in spleen, mesentery and muscle without significant differences between them, followed by the significantly higher values of Thunderbeat. Nevertheless, Thunderbeat produced the significantly lowest mean MTZtotal in the liver. EnSeal produced the lowest mean MTZcollat in the liver, followed by LigaSure and Thunderbeat showing significant differences. EnSeal and LigaSure produced the lowest mean MTZcollat in the spleen, mesentery and muscle without significant differences between them, followed by the significantly higher values of Thunderbeat. Based on the results of this study, Thunderbeat seems to be more invasive to tissue integrity (even without the activation of the ultrasonic scissor function) than EnSeal or LigaSure, that operate at lower temperatures and were found to cause negligible collateral thermal damage.
