Disinfection of Infected Artificial Dental Periapical Lesions with Diode Laser: An In Vitro Study.

BACKGROUND Periapical lesions are primarily caused by infections in the root canals. The objective of this study was to assess the antibacterial effectiveness of diode laser during root canal treatment in artificial models of infected periapical lesions. MATERIAL AND METHODS One hundred twenty-two extracted premolar single-rooted teeth were inserted into methyl methacrylate artificial models of periapical lesions, and bacterial solutions of Enterococcus faecalis (ATCC 29212) and Streptococcus mitis (ATCC 49456) were then applied to the models. The respective diameters of lesions in the artificial models represented 3 different subgroups based on lesion size. The laser protocol used for endodontic disinfection had a power output of 1.5 W and a wavelength of 810 nm. The impact on cell viability was evaluated by flow cytometry. RESULTS Disinfection with laser did not differ between microorganisms (P=0.137), and laser irradiation with a longer duration had better disinfecting action for both microorganisms (P.

Case report of ectopic hepatic tissue, a rare finding during a laparoscopic cholecystectomy.

INTRODUCTION: Ectopic hepatic tissue is due to an uncommon failure of embryological liver development. The incidence of ectopic liver has been reported to be anywhere from 0.24% to 0.47% and a prevalence rate of 0.47% as diagnosed at laparotomy or laparoscopy. We report a case of Ectopic Hepatic tissue attached to the gallbladder wall that was discovered during a laparoscopic cholecystectomy. CASE REPORT: A 47 year-old women presented to the surgery department with abdominal acute pain. The patient was taken for a standard laparoscopic cholecystectomy. The gallbladder was retracted cephalad while Hartmann's pouch was retracted laterally. It was then noted that an ectopic tissue was present on the gallbladder wall. The patient recovered well after surgery, had no complications and was discharged the day after surgery. DISCUSSION: Ectopic hepatic tissue is a rare condition. The real incidence of ectopic hepatic tissue attached to the gallbladder wall is difficult to assess but is reportedly 0.24-0.47% of the population. Ectopic hepatic tissue attached to the gallbladder usually remains asymptomatic and is occasionally discovered during laparoscopy, as was the case with the patient in the present report. In this case presented, the histopathological examination of specimen was confirmed to be ectopic liver tissue without hepatocellular carcinoma. CONCLUSION: It is important to be vigilant of ectopic hepatic tissue, their complications, and the potential surgical, including increased operative time and the need to follow up on such patients to rule out any possible complications.

Case report of cholelithiasis in a patient with type 1 Gaucher disease.

INTRODUCTION: Patients with type 1 Gaucher disease have been reported to be more likely to have cholelithiasis. PRESENTATION OF CASE: A case of cholelithiasis in a patient with type 1 Gaucher disease; which is very intriguing to show this comorbidity. The case was the only known case with this pathology in time of diagnosis in our country (Kosovo). The patient is a 21-year old girl a known case of type 1 Gaucher disease, at the age of 8 years. The patient underwent elective laparoscopic cholecystectomy. Chronic inflammatory changes and adhesions were obvious during surgery. DISCUSSION: Type 1 Gaucher disease patients have several risk factors for gallstone formation: increased biliary excretion of glucosylceramide, advanced liver disease and cirrhosis, splenomegaly, inborn error of metabolism, chronic systemic inflammation, T cell dysfunction, and insulin resistance" to risk factors. CONCLUSION: Gallstones and cholecystitis should be considered when abdominal symptoms and liver dysfunctions are seen in these patients. More studies are needed in especially Kosovo.
