Koloskopické vyšetření je klíčová metoda pro prevenci, diagnostiku i léčbu onemocnění tlustého střeva. Součástí koloskopického vyšetření je příprava střeva před samotným zákrokem, spočívající ve vyprázdnění střeva pomocí perorálně užívaných lavážujících látek a s tím související přechodná změna diety. Tato příprava může u pacientů s diabetes mellitus vést k rozkolísání glykemie a riziku hypoglykemie. Kazuistika popisuje případ pacienta s diabetes mellitus 1. typu léčeného pomocí hybridního uzavřeného okruhu, který v rámci přípravy na koloskopické vyšetření využíval na základě dat z kontinuální monitorace glykemie sáčky s 5 gramy sacharózy k doplnění energie a stabilizaci glykemie. Glykemie se v průběhu přípravy pohybovaly
Colonoscopy is a key method for preventing, diagnosing, and treating colon diseases. The colonoscopic examination includes preparing the colon before the procedure, which involves emptying the bowel with orally administered lavage agents and the associated temporary change in diet. This preparation can lead to glycemic fluctuations and the risk of hypoglycemia in patients with diabetes mellitus. This case report describes the case of a patient with type 1 diabetes mellitus treated with a hybrid closed-loop system who used 5 grams of sucrose sachets during colonoscopic preparation to replenish energy and stabilize glucose based on continuous glucose monitoring data. Glycemia during preparation kept within recommended values 3.9-10.0 mmol/l.

The use of local therapy with antibiotics in a suitable carrier is essential in the treatment and prevention of infections in orthopedic surgery and traumatology. In our orthopedic surgery department, a synthetic calcium sulfate hemihydrate (CaSO4·1⁄2H2O) is used as an antibiotic carrier, enabling the application of most types of intravenous antibiotics in the form of powder and liquid. This type of carrier with antibiotics is prepared in the theater during the procedure. During a surgical procedure, a small dead space is created (hand and foot area), which must be filled with an antibiotic carrier, and the situations arise where a large amount of the carrier is not used and thrown away. Therefore, we verified the efficacy of vancomycin in the pre-prepared carrier by an orientation microbiological method and by measuring the concentrations of the vancomycin released in active form and its two crystalline degradation products. Based on the agar diffusion test, we did not measure any difference in the effectiveness of the antibiotic in the carrier after its 12-day storage. Although vancomycin concentrations decreased by approximately 32% at the end of 12 days of storage, the concentrations of the released active form of vancomycin are many times higher than the minimum inhibitory concentrations for resistant strains of Staphylococcus aureus. Thus, the calcium sulfate carrier with vancomycin can be prepared several days in advance before its application, certainly up to 12 days.
Vancomycin is often used in orthopedic surgery as a local prophylaxis of bacterial infection. The aim of this work was to compare the release of vancomycin and its biologically inactive crystalline degradation products (CDP-1) during in vitro experiments from different types of local antibiotic delivery systems (bone grafts and bone cements). The concentrations of vancomycin and its crystalline degradation products were determined by high-performance liquid chromatography. Each experiment was performed in a phosphate buffer solution over 21 days. Morselized bone grafts, synthetic bone cements Palacos and Copal, and synthetic bone grafts were tested as local carriers of vancomycin. The highest concentration approximately 670 mg/L of vancomycin was released from synthetic bone grafts Actifuse. Even after 21 days, the concentration of vancomycin was still above the minimum inhibitory concentration (MIC). The maximum concentration of vancomycin released in two experiments with human bone grafts exceeded 600 mg/L during the first day and was still above MIC level 21 days later when the experiment was concluded. By comparing the synthetic bone cements Palacos and Copal, Copal had the average maximum concentration of only 32.4 mg/L and Palacos 35.7 mg/L. The concentration of vancomycin fell below the MIC for vancomycin-resistant Staphylococcus aureus (VRSA) on the seventh day with Palacos and the ninth day with Copal. This study showed the insufficient concentration of released vancomycin from synthetic bone cements at the end of the experiment. For improvement of local prophylaxis, it would be beneficial to increase the amount of vancomycin in bone cements.
