RESUMO

BACKGROUND: Surgical Site Infection (SSI) is the third most frequent nosocomial infection, and accounts for 14-16% of all infections. While the treatment of SSI can be very costly, previous results indicated that triclosan may reduce SSI rate. Therefore, we carried out a prospective randomised trial to further evaluate the effect of triclosan after elective colorectal surgery. METHODS: Seven surgical units in Hungary were involved in a prospective, randomised, multicentric clinical trial to compare triclosan coated (PDS plus®) and uncoated (PDS II®) sutures for abdominal wall closure in elective colorectal surgery. Pre- and perioperative variables were recorded in an online database. The primary aims of the study were to determine the incidence of SSI and the pathogens associated with it, as well as evaluation of additional cost of treatment. RESULTS: 485 patients were randomised. SSI occurred in 47 cases (12.5%), of those 23 (12.23%) from the triclosan group (n = 188) and 24 (12.18%) from the uncoated group (n = 197, p = 0.982). In 13 (27.66%) cases late appearance of SSI was detected, of those 4 patients with triclosan coated suture (8.51%) and 9 patients with uncoated suture (19.15%, p = 0.041). There was no difference between the type of incisions or elective colon and rectal resections in terms of incidence of SSI. CONCLUSION: Beneficial effect of triclosan against Gram positive bacteria could not be confirmed in our study due to the relatively low number of patients with SSI. Furthermore, triclosan did not influence the incidence of SSI due to Gram negative bacteria. SSI rate decreased by 50% compared to our previous study, however, it was regardless of the use of coated or uncoated PDS loop. Finally, operative factors were more important than patient's risk factors in terms of incidence of SSI. In case SSI developed, delayed discharge from hospital as well as special wound care significantly increased overall cost of treatment.

RESUMO

Dentigerous cyst is a developmental odontogenic cyst, which apparently develops by accumulation of fluid between the reduced enamel epithelium and the tooth crown of an unerupted tooth. Management of dentigerous cyst in primary dentition needs special consideration regarding the preservation of the developing permanent tooth buds. A case of dentigerous cyst is reported in primary dentition of a 7-year-old female patient and its management. By extracting the infected primary teeth, opening the cyst and ensuring continuous drainage, it is possible to achieve spontaneous eruption of the involved permanent teeth into the dental arch even if they are badly dislocated. Simultaneous with the eruption of the permanent teeth, ossification of the bony defect can take place. The reparatory process is completed in one to two years, during this time the patient has been given a space-maintainer.

RESUMO

In this study, we present an optimised colourimetric and a lateral flow LAMP assay for the detection of Haemonchus contortus in small ruminant faecal samples. Using a previously published LAMP primer set, we made use of commercially available colourimetric LAMP and lateral flow kits and combined this into an optimised diagnostic assay which was then tested on field faecal samples from Eastern and South-Eastern Hungary as well as a pure H. contortus egg faecal sample from Kosice, Slovakia. Both assays showed no conflicts in visual detection of the results. Additionally, we modified and tested several centrifuge-free DNA extraction methods and one bead-beating egg lysis DNA extraction method to develop a true point of care protocol, as the source of the starting DNA is the main rate-limiting step in farm-level molecular diagnosis. Out of the various methods trialed, promising results were obtained with the magnetic bead extraction method. Sample solutions from the Fill-FLOTAC® technique were also utilised, which demonstrated that it could be efficiently adapted for field-level egg concentration to extract DNA. This proof of concept study showed that isothermal amplification technologies with a colourimetric detection or when combined with a lateral flow assay could be an important step for a true point of care molecular diagnostic assay for H. contortus.


TITLE: Dosage LAMP colorimétrique et à flux latéral pour la détection au point d'intervention d'Haemonchus contortus dans les échantillons de selles de ruminants. ABSTRACT: Dans cette étude, nous présentons un test colorimétrique optimisé et un test LAMP à flux latéral pour la détection d'Haemonchus contortus dans des échantillons de selles de petits ruminants. À l'aide d'un ensemble d'amorces LAMP publié précédemment, nous avons utilisé des kits colorimétriques LAMP à flux latéral disponibles dans le commerce et les avons combinés dans un test de diagnostic optimisé qui a ensuite été testé sur des échantillons de matières fécales de terrain provenant de l'est et du sud-est de la Hongrie ainsi que d'un échantillon d'œufs de H. contortus provenant de selles de Kosice, Slovaquie. Les deux tests n'ont montré aucun conflit dans la détection visuelle des résultats. De plus, nous avons modifié et testé plusieurs méthodes d'extraction d'ADN sans centrifugation et une méthode d'extraction de l'ADN des œufs par lyse par billes pour développer un véritable protocole de point d'intervention, car la source d'ADN de départ est la principale étape limitante du diagnostic moléculaire au niveau de la ferme. Parmi les différentes méthodes testées, des résultats prometteurs ont été obtenus avec la méthode d'extraction par billes magnétiques. Des solutions d'échantillons de la technique Fill-FLOTAC® ont également été utilisées, ce qui a démontré qu'elle pouvait être efficacement adaptée à la concentration d'œufs sur le terrain pour extraire l'ADN. Cette étude de preuve de concept a montré que les technologies d'amplification isotherme avec une détection colorimétrique ou lorsqu'elles sont combinées avec un test de flux latéral pourraient être une étape importante pour un véritable test de diagnostic moléculaire au point d'intervention pour H. contortus.

RESUMO

Helminth infections, mainly by gastrointestinal nematodes (GIN), are one of the main concerns for animal health, welfare and productivity in grazing ruminant livestock worldwide. The use of a sensitive, precise, accurate, low-cost, and easy-to-perform copromicroscopic technique is of pivotal importance to perform reliable fecal egg count (FEC) and fecal egg count reduction test (FECRT), in order to determine the need of anthelmintic treatment, but also anthelmintic efficacy or resistance. This approach is fundamental to a correct and efficient control of GIN. Unfortunately, in worldwide ruminant farm practice, repeated anthelmintic treatments are carried out, without prior diagnosis of infection, contributing to the spread of Anthelmintic Resistance (AR). Tackling this phenomenon, improving mainly the GIN diagnosis and AR status in farm animals, is a priority of the European COST Action "COMBAR-COMBatting Anthelmintic Resistance in Ruminants" and of the STAR-IDAZ International Research Consortium on Animal Health. One of the specific objectives of the COMBAR Working Group 1 (WG1) is to conduct an European market analysis of new diagnostics and develop a business plan for commercial test introduction, leveraging technical know-how of participants. Since the Mini-FLOTAC in combination with the Fill-FLOTAC may be considered a good candidate for a standardized FEC and FECRT in the laboratory, as well as directly in the field, the aim of this study was to conduct SWOT (Strength-Weaknesses-Opportunities-Threats) and PESTEL (Political, Economic, Social, Technological, Environmental, and Legal) analyses of these tools in 20 European countries involved in the COMBAR WG1, in order to identify the opportunities, barriers, and challenges that might affect the Mini-FLOTAC and Fill-FLOTAC commercialization in Europe.
