Comparative Evaluation of N-Butyl Cyanoacrylate and Silk Sutures on Healing of Periodontal Flaps: A Clinico Histological Evaluation.

Background The periodontal flap is one of the most frequently employed procedures. Closure of reflected flap is important step in flap surgery. Black silk sutures are most often used material in routine surgical procedures. These suture materials demand more time and effort and expertise from the surgeon. Tissue adhesives have been developed as alternatives to overcome these problems such as cyanoacrylates. Objective The present study is an attempt to compare effectiveness of the black silk suture with cyanoacrylate adhesives in closing reflected periodontal flap. Method Thirty systemically healthy patients who underwent bilateral flap surgery were given 3-0 black silk sutures on one side and N-butyl cyanoacrylate adhesive on the other side to close a surgical incision. All the participants in the study were recalled on the seventh, 21st, 42nd day. Participants were evaluated for healing and plaque accumulation by assessing the gingival index, plaque index, wound healing index. Biopsy specimens were obtained on seventh and 42nd postoperative day. Result The amount of inflammation was less during the first week of healing when cyanoacrylate was compared with silk. However, over a period of 21 days to 42 days, the sites treated with both the materials showed similar healing patterns without any significant difference in the evaluated parameter. Conclusion The result of the study showed that the use of cyanoacrylate for the closure of periodontal flaps results in better initial post-operative healing as compared to closure with silk suture and that this method of closure can be advocated in a routine surgical periodontal practice.

Novel ambulatory glucose-sensing technology improves hypoglycemia detection and patient monitoring adherence in children and adolescents with type 1 diabetes.

PURPOSE: Glucose monitoring [GM] is a mainstay of diabetes control and management. Improving glycemic control is essential to prevent microvascular complications. However, adherence to GM can be a challenge in children and adolescents. Detecting hypoglycemia is essential for its prevention and treatment. We aim to study the impact of the flash ambulatory glucose monitoring in detecting hypoglycemia and enhancing adherence in children and adolescents with type 1 diabetes. METHODS: The study is prospective involving 3 hospital visits. Children and adolescents with diabetes were enrolled in the study which involved a period on conventional glucose self-monitoring [glucometers] followed by a similar period of monitoring using the flash glucose monitoring device (FreeStyle Libre). Frequency of GM, duration and frequency of hypoglycemia were compared on conventional and the flash monitoring. RESULTS: 75 subjects were studied. Age mean (range) was 11.9 years (2-19). Significant difference was seen in hypoglycemia detection between both testing devices. 68 (94%) and 65 (90%) patients detected nocturnal and diurnal hypoglycemia respectively on Flash monitoring compared to 12 (16.6%) and 30 (41%) on glucometer testing (p < 0.00). Mean (range) duration of hypoglycemia was 95 min (15-330). Statistically-significant difference was found between the frequency of GM on glucometer testing compared with Flash monitoring (2.87 and 11.6/day) (p < 0.001). CONCLUSIONS: Flash monitoring is a useful tool to improve adherence to GM and detecting hypoglycemia [diurnal and nocturnal] in children and adolescents with type 1 diabetes.

Identification of Candida species in vaginal flora using conventional and molecular methods.

Vaginal swab samples were collected both from women with signs of acute vulvovaginal candidiasis (VVC; n=270) and from healthy controls (n=100). The microscopic examination revealed a significant difference in the proportion of positive cultures of Candida between the VVC (33%) and control (21%) groups. To determine the frequency of different species, positive cultures were analyzed using the germ tube test, CHROMagar medium, API 20 AUX System and DNA analysis. CHROMagar and API 20 AUX System tests identified 67% of samples as C. albicans. Out of these, 42% appeared to be C. dubliniensis when the specific primers in the polymerase chain reaction (PCR) were used. We observed the prevalence of Candida species isolated from the vagina in descending order as follows: C. albicans (38-39%), C. glabrata (32-33%), C. dubliniensis (28-29%) and C. tropicalis (0-1%) for both the VVC and the control group.

Doppler ultrasound in the assessment of suspected intra-uterine growth restriction.

Small fetuses constitute a large heterogenous group that includes healthy small fetuses, chromosomally abnormal fetuses and fetuses suffering from utero-placental insufficiency leading to restriction in fetal growth. This review outlines the diagnosis of intra-uterine growth restriction and describes how to differentiate this group from the group of healthy small fetuses. This is very crucial in the management of small fetuses in order to avoid unnecessary intervention in the healthy group, as well as avoid stillbirth and neonatal mortality and morbidity.
