PURPOSE: We present a new simple technique to remove subconjunctival cyst under the slit lamp microscope. CASE SUMMARY: A cotton swab was used to verify whether or not the cyst was freely movable under the conjunctiva. After topical anesthesia, we incised the conjunctiva near the cyst using a 30-gauge needle and extracted the cyst through the wound using forceps under the slit lamp microscope. Four cases of subconjunctival cyst were successfully removed with our new technique. During the average five month (2-10 month) follow-up period, there was no recurrence or procedure-related complications. CONCLUSIONS: Some subconjunctival cysts such as an epithelial inclusion cyst which is freely movable without attachment to surrounding tissues can be easily removed with a 30-gauge needle and forceps under the slit lamp microscope. This could be considered as the primary procedure instead of simple aspiration.

PURPOSE: To report a case of supratarsal injection of triamcinolone for the management of chronic, steroid-dependent Thygeson's superficial punctate keratitis. CASE SUMMARY: A 37-years-old woman complained of redness, photophobia, and tearing in both eyes, which lasted for 6 years. The slit lamp examination revealed multiple intraepithelial and subepithelial, punctated corneal lesions which were elevated and scattered diffusely upon staining with fluorescein dye in both eyes. The patient was diagnosed with Thygeson's superficial punctate keratitis and treated with 0.1% fluorometholone, 0.05% cyclosporin, and 0.15% ganciclovir in both eyes. After 10 months of follow-up, recurrences were reported twice in the right eye, and 7 times in the left eye. The patient was treated with a supratarsal injection of triamcilonone in both eyes and after injection, the patient was treated only with artificial tears. Four months later, the patient did not complain of any symptoms and her cornea was clear. CONCLUSIONS: A supratarsal injection of triamcinolone may be an effective method to prevent recurrence of chronic, steroid-dependent Thygeson's superficial punctate keratitis.

Orthostatic or postural proteinuria is the most common cause of asymptomatic proteinuria in children. As orthostatic proteinuria (OP) is a benign disease with relatively good prognosis, it has no specific management, and patients only need to be observed. However, if OP shows a persistently high level of proteinuria, in theory, glomerular changes can occur. An 11-year-old girl was referred to the hospital due to asymptomatic proteinuria and was diagnosed as having OP based on the results of clinical and laboratory examinations, urinalysis, and protein/creatinine (TP/Cr) ratio at both supine and erect positions. During follow-up observation, the 24-hour TP/Cr ratio was persistently higher than 1.5 mg/mg for 2 years. We performed renal biopsy, which showed mesangial proliferative glomerular lesions with focal effacement of the podocyte foot processes, but without immune depositions. OP can be accompanied by glomerular lesions if moderate to severe proteinuria persists.

We developed the BaSDAS (Barcode-Seq Data Analysis System), a GUI-based pooled knockout screening data analysis system, to facilitate the analysis of pooled knockout screen data easily and effectively by researchers with limited bioinformatics skills. The BaSDAS supports the analysis of various pooled screening libraries, including yeast, human, and mouse libraries, and provides many useful statistical and visualization functions with a user-friendly web interface for convenience. We expect that BaSDAS will be a useful tool for the analysis of genome-wide screening data and will support the development of novel drugs based on functional genomics information.

PURPOSE: To report the symmetric masses developed in both eyes, which were diagnosed with bilateral osseous choristoma and surgically excised. METHODS: A 6-year-old female was noted by her parents to have a mass under the conjunctiva of her left eye. The mass was white and firmly attached to the globe. The same lesion was present in the right eye. CT scan showed that the masses were high bone-density and did not invade the sclera deeply. Therefore, excisional biopsy of the lesions were performed. RESULTS: Histopathologic examination showed that the masses were episcleral osseous choristoma. There was no complication of recurrence or adhesion after surgery. CONCLUSIONS: In case of a hard mass under the conjunctiva, which is diagnosed with osseous choristoma by CT scanning, it is helpful to determine the accurate location and adhesion of the massfor successful surgery.

PURPOSE: To evaluate the parameters affecting vaulting and correlation between preoperative crystalline lens rise and vaulting after implantable collamer lense (ICL) implantation. METHODS: A total of 53 eyes of 34 patients who underwent ICL implantation were examined retrospectively. White-to-white (WTW) and anterior chamber depth (ACD) were obtained from scanning topography (ORB scan) before surgery. Preoperative crystalline lens rise (CLR) and vaulting at 6 months after ICL implantation were measured using anterior segment optic coherence tomography (AS-OCT). Multiple regression analysis was performed to evaluate the factors affecting central vaulting. RESULTS: The mean preoperative crystalline lens rise was -120 +/- 219 microm, and mean central vaulting 6 months after surgery was 544 +/- 175 microm. Preoperative SE, WTW, ACD, and CLR were significantly correlated with vaulting at 6 months after surgery. With the use of meaningful variables, multiple regression analysis showed that CLR, WTW, ACD and SE, in that order of influence, had significant effects on vaulting and the multiple regression equation was obtained as follows: Vaulting (microm) = (160.913 x ACD (mm)) + (170.134 x WTW (mm)) + (-0.338 x CLR (microm)) + (-23.783 x SE (D)) - 2250.184. CONCLUSIONS: CLR had a stronger influence on vaulting after ICL implantation than the previously proven parameters: WTW, ACD, and SE. In addition to WTW, ACD and SE, CLR should also be considered a new criterion for estimating vaulting after ICL implantation.

BACKGROUND: Waist circumference is one of the key components of metabolic syndrome. Recent studies demonstrated that the reproductive profile was associated with metabolic syndrome in postmenopausal women. This study focused on the association between central obesity and age at first childbirth. It also considered other factors associated with central obesity in postmenopausal women. METHODS: This study was based on the 2013–2015 Korean National Health and Nutrition Examination Survey and involved 3,143 naturally postmenopausal women. These women were divided into three groups according to their age at first childbirth: 19 years or younger (n=252), 20–29 years (n=2,695), and 30 years or older (n=196). Multivariate analysis using logistic regression was performed to evaluate the effects of various reproductive factors, including other confounding factors. RESULTS: During adjustment for confounding factors, in the early age at first childbirth group, odds ratios (95% confidence intervals) for central obesity decreased. In the final model, younger age at first childbirth was not significantly related to central obesity (waist circumference more than 85 cm) in naturally postmenopausal women after adjusting for other confounding factors. CONCLUSION: Younger age at first childbirth was not significantly associated with central obesity after adjustment for confounding factors.

Tetanus is rare in Korea due to the introduction of vaccination programs and the advancement in public health. Its common signs are trismus, voice disturbance, neck stiffness, and difficulty in swallowing, etc. A 56 years old man was injured by grasping a high voltage electric cable. After the accident, he fell down on a steel plate and had a head trauma. When he visited Emergency Department, there was multiple electric burn wound on left arm and left facial area. He was hospitalized on a department of neurosurgery, because intra cranial hemorrhage was presumed. 12 days later, he was referred to department of OMFS with developed painful masseter spasms and trismus. That night he violently bit his tongue with his denture. Because masseter muscle and temporal muscle constriction was involuntary, tongue was lacerated and denture was distorted. At first we supposed that the symptom was related with neurologic disturbance following head trauma or electric shock. But it was revealed that trismus was caused by tetanus on an electrophysiological test. By using mechanical ventilation and administration of tetanus immunoglobulin, muscle-relaxant, and sedatives at ICU, symptoms had subsided (4-weeks). Because tetanus is rare disease, we rarely suppose tetanus infection to be a cause of a trismus. Especially it is more difficult to diagnose in patient who has head trauma, burn and neurologic problem as in this case.
