Background: Temporomandibular joint (TMJ) disorders affect roughly 5% of the population. Chronic closed lock is one of the more common temporomandibular disorders and is characterized by limited mouth opening and various degrees of joint pain and dysfunction. 

Objectives: To evaluate the efficacy and safety of arthroscopic lysis and lavage of the TMJ to treat limited mouth opening in patients suffering from chronic closed lock. 

Methods: This is a retrospective analysis of the medical records of 47 patients with chronic closed lock treated with arthroscopic lysis and lavage. Patients were diagnosed preoperatively with closed lock of the TMJ and were unresponsive to previous conservative therapy. Three outcome variables were used to assess the efficacy of treatment: maximal mouth opening, subjective evaluation of overall improvement by the patient (on a 3 grade scale: “excellent,” “fair,” and “poor”), and length of hospital stay. In addition, complications were reported. 

Results: The maximal mouth opening values increased from a mean of 27 ± 4.7 mm preoperatively to a mean of 38 mm ± 5.4 mm postoperatively. The subjective evaluation of overall improvement was “excellent” in 15 patients (32%), “fair” in 21 (45%), and “poor” in 11 (23%). Success was defined as a maximal mouth opening of 35 mm or more after arthroscopy, and not reporting a “poor” result in the subjective evaluation. This was achieved in 36 patients, yielding a success rate of 77%. The mean length of hospital stay was less than one day (0.78 days). The complication rate was low (8%) and all complications resolved within 2 weeks. 

Conclusion: Arthroscopic lysis and lavage is a simple, safe, and efficient minimally invasive intervention for the treatment of chronic closed lock of the TMJ.

Background: Despite the ongoing decrease in the incidence of gastric cancer, this disease is still a major cause of death. It is still debatable whether D2 lymphadenectomy improves survival and whether this procedure should be performed routinely or selectively.


Objectives: To compare the pathological and short-term results following radical D2-type gastric resection and lymphadenectomy versus the more limited D1 type resection and lymphadenectomy.


Methods: We conducted a retrospective study on 4 years experience treating 164 patients suffering from gastric cancer. We compared the results between the group of patients who underwent a radical D2 type gastric resection and lymphadenectomy (n=100) and those of a relatively small group of patients who intentionally underwent the more limited D1 type (n=34). 


Results: The overall number of harvested lymph nodes was 9 ± 4 in the D1 group compared to 30 ± 12 (range 16–69) in the D2 group (P = 0.001). Of the 100 patients undergoing a D2 lymphadenectomy, 57% had positive nodes compared to 38% of the 34 patients in the D1 group (P = 0.045).


Conclusions: We showed statistically significant differences between D1 and D2 procedures in the overall number of harvested lymph nodes and the proportion of positive nodes to the overall number. Our results support the fact that D2 resection should be recommended as the standard approach of treatment for gastric cancer patients, ensuring a larger number of retrieved lymph nodes and a comparable rate of complications and mortality.

Background: Oral lichen planus is a cell-mediated immune condition of unknown etiology. A possible association of OLP[1] with hepatitis C virus infection has been documented in specific populations. However, no such possible association has been studied in Israel.

Objectives: To assess the prevalence of HCV[2] antibodies among patients with OLP in Israel.

Methods: The prevalence of HCV seropositivity was studied in OLP patients (n=62) and compared with that of a control group (n=65) and with the prevalence among healthy volunteer blood donors (n=225,452) as representatives of the general population.

Results: The prevalence of HCV, as detected by the presence of anti-HCV antibodies screened by enzyme-linked immunosorbent assay, and confirmed by recombinant immunoblot assay, was 4.8%, 1.5% and 0.1%, respectively. HCV seropositivity in the OLP patients was significantly higher than in the healthy blood donors (P < 0.001).

Conclusions: A possible association between OLP and HCV is suggested. Therefore, screening OLP patients for antibodies to HCV is recommended.
