Apocrine Fibroadenoma of the Perianal Region Associated with Perianal Fistula

A case of a 45 year-old woman who presented with a perianal fistula was reported. Histologically, the excised lesion showed features of apocrine fibroadenoma. In addition, the lesion had both glandular and stromal growth patterns and active chronic inflammation in the background. Malignant or benign counterparts of these types of lesions are widely described in literature. However fistula does not usually accompany and is very rare. Therefore, it is crucial for the pathologists and clinicians to be aware of such lesions. The relationship between apocrine fibroadenoma and perianal region was also discussed

Effect of premedication on hemodynamics and bispectral index in pediatric dental rehabilitation

Objectives: The aim of this study was to evaluate the effects of rectal midazolam premedicationon hemodynamic parameters and Bispectral Index Scale (BIS) values in children undergoinggeneral anesthesia (GA) for dental rehabilitation.Materials and Methods: Records of 30 children aged 2 to 7 years were retrieved and dividedinto 2 groups. Group 1 received midazolam 0.3mg/kg body weight rectally and group 2involved children who did not receive any presedative (control). Mean arterial blood pressure(MAP), heart rate (HR), oxygen saturation (SpO2), and BIS were evaluated for six times; beforelaryngoscopy(1); 1 min(2); 5 min(3); 10 min after nasotracheal intubation(4); at the time ofextubation (5) and at the time of recovery(6). Paired t-test was performed to analyze all data.p<0.05 was defined as statistically significant.Results: MAP and HR did not differ significantly between both groups before laryngoscopy(p>0.05) but increased significantly in control group 1 min after intubation (p<0.04). SpO2was in the normal range in both groups, which was statistically insignificant (p>0.05). The BISrecords of the midazolam group were slightly lower than the control group in general but thisdifference was insignificant (p>0.05).Conclusions: Midazolam premedication prior to GA induction resulted with lower MAP and HRthan the control group 1 minute after intubation whereas it did not alter BIS values remarkablyat all time intervals. Therefore, the midazolam sedation did not produce a significant change inreducing GA awareness in children undergoing GA for dental rehabilitation

Effect of Er:YAG laser enamel conditioning and moisture on the microleakage of a hydrophilic sealant

For a given sealant, successful pit and fissure sealing is principally governed by the enamel conditioning technique and the presence of moisture contamination. A new generation of hydrophilic resin sealants is reported to tolerate moisture. This study investigates the impact of Er:YAG laser pre-conditioning and moisture contamination on the microleakage of a recent hydrophilic sealant. Occlusal surfaces of extracted human molars were either acid etched (n = 30), or successively lased and acid etched (n = 30). Ten teeth from each group were either air-dried, water-contaminated, or saliva-contaminated prior to sealing with UltraSeal XT® hydro™. Samples were inspected for penetration of fuchsin dye following 3000 thermocycles between 5 and 50 °C, and the enamel–sealant interfaces were observed by scanning electron microscopy (SEM). Significant differences in microleakage were evaluated using the Mann–Whitney U test with Bonferroni adjustment (p = 0.05). Laser pre-conditioning significantly reduced dye penetration irrespective of whether the enamel surface was moist or dry. Microleakageof water-contaminated acid etched teeth was significantly greater than that of their air-dried or saliva-contaminated counterparts. SEM analysis demonstrated good adaptation in all groups with the exception of water-contaminated acid etched teeth which exhibited relatively wide gaps. In conclusion, this hydrophilic sealant tolerates the presence of saliva, although water was found to impair its sealing ability. Laser pre-conditioning significantly decreases microleakage in all cases

The effect of neostigmine on postoperative ileus and the healing of colon anastomoses

Ruptured mesenteric cyst: a rare presentation after trauma

Mesenteric cysts are rare intraabdominal benign cystic lesions. These lesions are most commonly located in the ileal mesentery, without any sex predilection. Mesenteric cysts may be totally asymptomatic and discovered incidentally during routine radiologic examinations. Chronic abdominal pain or acute abdomen may be accompanying to these lesions. Ultrasonography, computed tomography and magnetic resonance imaging are valuable in the diagnosis. Rarely, these lesions may be presented with rupture after trauma. We present a patient with a ruptured ileal mesenteric cyst due to a blunt abdominal trauma and diagnosed by emergency laparotomy

Transdiaphragmatic blockage of the lymphatic may reduce bacterial translocation

PURPOSE: Bacterial translocation is a spread of living and non-living bacteria and bacterial end-products, passing over the mucosal barrier distending mesenteric lymph nodes, blood and viscera. DuraSeal(polyglycolic acid glue) has adhesive power and it usually used in brain or spinal surgery. We aimed to show the barrier system effect using experiments, in which intraabdominal infection induced and translocation from diaphragm to thorax is researched

The effects of laparoscopic mesh fixation device on bone, costo-chondral junction and tendon site

Osteitis pubis is one of the important complications of inguinal hernia repair surgery occurring with the placement of sutures through the periosteum. The aim of this study is to evaluate scintigraphic and histopathological alterations associated with the use of mesh fixation device on pelvic bone, cartilage and tendons in an experimental animal model. Twenty New-Zealand young male rabbits were used. A mesh fixation device was inserted at each animal's costa-chondral junction, superior anterior iliac crest, and achiles tendon. One week prior to the surgery and 16 weeks after the operation, scintigraphic evaluation was performed. Histopathological evaluation was performed at the end of study. No nuclear activity or pathological change was found at bone site (p > 0.05). Foreign body reaction was evident at the tendon and costa-chondral site (p=0.001)

Efficacy of Biodentine as an Apical Plug in Nonvital Permanent Teeth with Open Apices: An In Vitro Study

The aim of this study was to evaluate the apical microleakage of Biodentine and MTA orthograde apical plugs and to compare the effect of thickness of these biomaterials on their sealing ability. A total of eighty maxillary anterior teeth were used. The apices were removed by cutting with a diamond disc (Jota, Germany) 2 mm from the apical root end in an attempt to standardize the working length of all specimens to 15 +/- 1 mm. Both materials were placed in 1-4 mm thickness as apical plugs root canal. Root canal leakage was evaluated by the fluid filtration technique. One-way ANOVA was used in order to determine normality of dispersal distribution of parameters; thereafter, results were analyzed by Kolmogorov-Smirnov test. Overall, between microleakage values of MTA and Biodentine regardless of apical plug thickness, no difference was observed. In terms of plug thickness, a statistically significant difference was observed between the subgroups of MTA and Biodentine (P < 0.05). The apical sealing ability of Biodentine was comparable to MTA at any apical plug thickness
