METHOD: A prospective, randomized, double-blinded controlled trial was conducted with 58 patients undergoing breast conserving surgery (BCS) and ALND, stratified into two groups: Group A (ALND + Haemoblock, n = 29) and Group B (ALND + placebo, n = 29). Postoperative drainage charts were monitored, with the primary endpoint being the time to drain removal, Additionally, patients were observed for surgical site infection (SSI).
RESULTS: Group A exhibited a marginally higher mean total drain output (398 +/- 205 vs. 326 +/- 198) compared to Group B, this difference did not attain statistical significance (p = 0.176). Equally, the mean time to drain removal demonstrated no discernible distinction between the two groups (6 +/- 3.0 vs. 6 +/- 3.0, Group A vs. Group B, p = 0.526). During follow up, nine patients in Group A required seroma aspiration (mean aspiration 31 +/- 73) as compared to Group B, 6 patients required aspiration (mean aspiration 12 +/- 36), p = 0.222). No notable disparity in SSI rates between the groups was identified.
CONCLUSION: In conclusion, the administration of Haemoblock did not manifest a discernible effect in mitigating seroma production, hastening drain removal, or influencing SSI rates following ALND. The study underscores the intricate and multifactorial nature of seroma formation, suggesting avenues for future research to explore combined interventions and protracted follow-up periods for a more comprehensive understanding.
METHODS: A prospective analysis of ninety nine H. pylori-positive patients who underwent endoscopy in our Endoscopy suite were included in this study. DNA was isolated from antral biopsy samples and the presence of cagA, iceA, and iceA2 genotypes were determined by polymerase chain reaction and a reverse hybridization technique. Screening for H. pylori infection was performed in all patients using the rapid urease test (CLO-Test).
RESULTS: From a total of 326 patients who underwent endoscopy for upper gastrointestinal symptoms, 99 patients were determined to be H. pylori-positive. Peptic ulceration was seen in 33 patients (33%). The main virulence strain observed in this cohort was the cagA gene isolated in 43 patients. cagA was associated with peptic ulcer pathology in 39.5% (17/43) and in 28% (16/56) of non-ulcer patients. IceA1 was present in 29 patients (29%) and iceA2 in 15 patients (15%). Ulcer pathology was seen in 39% (11/29) of patients with iceA1, while 31% (22/70) had normal findings. The corresponding values for iceA2 were 33% (5/15) and 33% (28/84), respectively.
CONCLUSION: Virulence factors were not common in our cohort. The incidence of factors cagA, iceA1 and iceA2 were very low although variations were noted in different ethnic groups.
