Thromboembolic tendency (TE) in IBD (Inflammatory bowel disease) patients.

BACKGROUND: The incidence of TE events in IBD patients is higher then in population control. The main reason of it, is the hypercoaugulable state. Our aim was to detect serum markers related to TE, that can assume preventing and prognostic meanings. MATERIALS AND METHODS: We performed a 3 years study on 71 patients with IBD, evaluating hypercoaugulability, and then we compared the results with a 71 patients non IBD group control. We also investigated patients of both groups concerning TE events occurred already. RESULTS: In IBD group we found out that 16 patients (22.5%) had history of TE versus >1% of group control. Nineteen of them, already had knowledge of their previous hypercoaugulating condition. 48 (67%) had increased markers value versus less then 6% detected in group control. In IBD group 43% ,20% and 4.2% had respectively 1, 1-3 or > 3 markers higher levels then normal range. Among the markers investigated, we detected increased levels of plated in 33%, homocysteine in 26.7%, d-dimero 25.3%, c3 in 15.4%, apcr in 5.6%. CONCLUSIONS: From our study we detected highest incidence of TE events, and hypercoaugulating status in IBD group. In our previous investigations, plated, homocysteine, d-dimero, c3, and apcr, seems to be the TE markers with higher sensibility. It seems reasonable, according our experience, to propose a new TE risk score index for IBD patients: low, mild and high risk respectively for patients with 1, 1-3 and >3 markers with higher serum levels then normal range. KEYWORDS: Inflammatory bowel disease, Thromboembolism risk score.

New method for bacterial load measurement during hydro-debridement of cutaneous ulcer.

AIM OF THE STUDY: Based on their experience using Versajet for debridement of chronic wounds, the Authors set up a study protocol to verify whether the hydro-surgical cleansing could offer the possibility of taking tissue specimens suitable for diagnostic microbiological evaluation. The aims of the study were the following: MAIN PURPOSE: To evaluate the efficacy of hydro-surgery in detecting the presence of microorganisms and measuring their load, as an alternative to conventional tissue sampling methods; SECONDARY PURPOSE: To set up an easier and less invasive diagnostic modality than surgical biopsy, even though likewise significant. RESULTS: The results of this study show that tissue specimen collection by hydro-aspiration using Versajet is comparable to biopsy sampling (and in some cases it can be even more reliable); moreover, it is not more time-consuming and is certainly less invasive. Compared to surgical biopsy, with such a method a greater amount of tissue may be collected; moreover, tissue specimens can be taken from a broader surface or, depending on the needs, from a more focused area on the margin or at the bottom of the wound.

Verification of the effectiveness of silver dressings to prevent reinfection of skin ulcers after debridement.

OBJECTIVE: To test the usefulness of silver dressings in patients with skin ulcers in the healing phase after debridement. MATERIALS AND METHODS: After randomly selected a group of 30 patients and divided them into three groups (A, B and C) according to the type and severity of the ulcer, we used respectively for each group antiseptics-free dressings, hydrofiber dressings with a low or a high content of silver. Then we performed samples by aspiration from the bottom of the wound three times (zero time, after two weeks, after a month) to prepare bacterial cultures. RESULTS: In group A, 5 ulcers showed signs of critical colonization after two weeks and 2 of these showed evidence of infection without progression to healing after a month. In groups B and C, no ulcer showed signs of infection with negative cultures. In these two groups, wounds evolved towards healing. CONCLUSIONS: Silver dressings seem to be the best option for the prevention of reinfection of skin ulcers; silver concentration should vary according to the degree of ulcer contamination. Dressings with hydrofibers avoid the accumulation of secretions for bacterial growth which would compromise tissue repair.

Abdominal hypertension and venous insufficiency of lower limbs: is there a relationship?

OBJECTIVE: The purpose of our study is to understand the compression, by subcutaneous fat in obese patients, who present a chronic increase in abdominal pressure, and on the sapheno-femoral cross. Such increase would result in a chronic venous insufficiency (CVI) of lower limbs and, if possible, it will be quantified also according to the posture. MATERIAL AND METHODS: We studied two different groups of patients with CVI: obese and non-obese. The severity of CVI was classified with the CEAP classification or by the standards of recent classifications. Abdominal pressure, by means of Kron's method, and anterior-sagittal diameter were measured in some of the non-obese patients (4 males and 4 females) and in all the obese patients. The diameter of the femoral vein of both groups of patients in supine, sitting and standing positions was also measured. RESULTS: We found a higher incidence of CEAP 5-6 classes in the obese group than in the non-obese one; we also saw a higher incidence of classes 1-2 in the non-obese group than in the obese one. Moreover, Kron's method showed a significant difference in abdominal pressure in relation to the BMI and the increase in the femoral vein diameter appears to be related to the weight and to the position. DISCUSSION: It was clear that the clinical manifestations of CVI are more severe in obese than in non-obese patients. Obesity in our study clearly acts with a continuous compressive action on the veins of the abdomen and thereby on the femoral vein, further contributing to a retrograde flow. So we tried to quantify an entity that until now could only be assumed.
