Familial lichen planus is an uncommon disease, and there are 104 cases reported in the English literature. Several theories regarding the etiopathogenesis of lichen planus have been proposed. However, immunological mechanisms and genetic susceptibility have been emphasized the most. Several reports showed HLA analysis in lichen planus patients, and recently 2 cases have revealed an increased frequency of DR1 antigen in patients with lichen planus compared to a control group. We observed two brothers with typical skin lesions of lichen planus of almost simultaneous onset. We confirmed lichen planus by skin biopsies in both brothers and analyzed HLA typing. We also observed the occurrence of DR1 antigen in both of them.

In Albright's hereditary osteodystrophy (AHO) including the syndromes of pseudohypoparathyroidism (PHP) and pseudopseudohypoparathyroidism (PPHP), multiple areas of intracutaneous ossification are often encountered. The characteristic features are short stature, round face, short neck, obesity, cutaneous ossifications, and various skeletal anomalies including short metacarpal and metatarsal bones, curve of radius, and brachydactyly. The patient was a 10-month-old male infant. He presented slightly depressed erythematous hard plaques on the left upper chest and left thigh. We had taken biopsies from both skin lesions, confirming cutaneous ossification or bone formation. He also had the characteristic features of AHO. He had a history of admission due to patent ductus arteriosus and atrial septal defect. The laboratory results showed slightly decreased calcium, increased phosphorus and PTH levels. The patient received no specific corrective measures because his calcium and phosphorus levels were not far from normal values until newly developed similar skin lesions appeared.

Currently several modalities are available for performing intracorporeal lithotripsy including ultrasound, electrohydraulic and laser procedures. We report our initial clinical experience with a new and unique technology for performing intracorporeal lithotripsy, namely the Swiss Lithoclast. 35 patients were performed for removal of ureteral stone. This device successfully fragmented 31 of 35 ureteral calculi (89%). Complications of stone removal were gross hematuria (3 cases), high fever (2 cases). All complications were treated successfully with conservative management. In conclusion, we have found the ability of the Swiss Lithoclast to fragment stones safely and without significant complications.

Purpose: To evaluate the effects and limitations of lacrimal endoscopy without silicone tube intubation in patients with epiphora. Methods: We conducted a retrospective chart review of 64 eyes in 49 patients who underwent lacrimal endoscopy between May 2021 and May 2022. The clinical characteristics, irrigation test results, lacrimal endoscopic findings, and type of surgery were analyzed. Results: The mean duration of symptoms was 31.2 months, and was significantly longer in the failure group than in the success group (p = 0.043). Irrigation tests showed passage, partial obstruction, and complete obstruction in 20 (31.3%), 16 (25.0%), and 28 (43.7%) eyes, respectively. Lacrimal endoscopy showed narrowing, mucus, fibrosis, granulation, and stones in 41 (64.0%), 12 (18.8%), 6 (9.3%), 3 (4.7%), and 2 (3.1%) eyes, respectively. Following lacrimal endoscopy, 32 (50.0%) eyes each were included in the success and failure groups. Preoperative irrigation test results did not affect the success rate (p = 0.203). Silicone tube intubation and dacryocystorhinostomy were performed in 5 (7.8%) and 8 (12.5%) eyes, respectively, because the symptoms did not improve after lacrimal endoscopy. Conclusions Lacrimal endoscopy, performed without silicone tube intubation, was effective in improving symptoms and may guide the choice of surgical technique, if required.

PURPOSE:To report a case of a granular cell tumor in the form of cilliary body tumor. CASE SUMMARY: A 42-year-old women visited our clinic with blurred vision of the right eye, which began was 1 month earlier ago. Her medical history was unremarkable. Slit-lamp examination revealed a ciliary body tumor and complicated cataract due to a mass lesion. For treatment, an excisional biopsy of the ciliary body tumor and phacoemulsification were performed. The pathologic finding confirmed the diagnosis of a granular cell tumor. There was no evidence of a recurrent lesion of the tumor at the 6-month postoperative follow-up. CONCLUSIONS: We confirmed a granular cell tumor in the form of a cilliary body tumor based on pathologic findings.

PURPOSE: We performed experiments to investigate the change in cellular signaling that occurs during the transformation of a normal cell to a cell capable of cancerous growth, and we did so by using the NIH 3T3 cells that were transformed by transfection with the v-Ha-ras oncogene. MATERIALS AND METHODS: Parental and v-Ha-ras transfected NIH 3T3 cells were chosen as test systems. The siRNA transfections were performed using Lipofectamine 2000. The cell proliferation reagent WST-1 was used for the quantitative determination of cellular proliferation. Immunoblot analysis was performed using the ECL-Plus chemiluminescent system and a KODAK Image Station 4000R. RESULTS: The v-Ha-ras-transformed cells were found to be significantly more resistant to PP2 treatment, which is a potent inhibitor of the Src family tyrosine kinases, than were the parental cells at earlier times after treatment. However, PP2 induced growth arrest and the senescence-like phenotypes in both cell lines after longer treatment. Furthermore, the Raf-1 kinase of the v-Ha-ras-transformed cells was not affected by the expressed level of Sprouty proteins, which are negative regulators of the MAPK pathway, as evidenced by the failure of siRNA-mediated knockdown of Spry4 to activate Raf-1 kinase. Dephostatin (a tyrosine phosphatase inhibitor) effectively inhibited the proliferation of the v-Ha-ras transformed cells, whereas dephostatin had only a small effect on the parental cells' proliferation. This implied an inhibitory role for tyrosine phosphatase that is specific to the signaling pathway in the v-Ha-ras transformed cells. CONCLUSION: Taken together, our results show that the sustained activation of the oncogenic pathways through their resistance to negative feedback regulation might contribute to the transformation of NIH 3T3 cells.
