Anaphylactoid nephritis is a disease complicated by anaphylactoid purpura manifested by a non-thrombocytopenic purpura, abdominal pain. And joint pain The manifestation of nephritis may vary from microscopic hematuria to acute rapidly progressive nephritic and nephrotic syndrome. This paper reports on anaphylactoid nephritis in children. These cases were collected fromthe Department of Pediatrics, Yonsei university Medical College from January 1,1974 to may 31, 1979. The results are as follows; 1. Among 75 cases of anaphylactoid purpura, 25 cases developed nephritis(33%), 16 cases were male and 9female. The age distribution was from 3years 5months to 15years. The peak incidence occured between 5 and 7years ofage with 11 cases. 2. The evidence of renal invovement in 18 cases among 25 were detected within 4 weeks after onset of skin manifestation. 3. The clinical manifestations were skin rashes, abdominal pain, joint pain, pitting edema, gross hematuria, and melena in orders. 4. The clinical classification of renal involvement were transient hematuria 4 cases, acute nephritis, 7 cases recurrent hematuria 1 case, nephrotic syndrome 5 cases, and undetermined 8 cases. 5. In additionto the usual signs of renal involvement, serum levels of IgA were checked. The elevation of IgA was 4 cases among the tested 6 cases. 6. According to the pathologic findings and immunofluorescent technique, 8 cases out of 9 cases by kidney biopsy were focal proliferative glomerulonephritis and 1 case diffuse proliferative flomerulonephritis. The deposit of glomeruli by immunofluorescent technique was IgA, IgG, IgM, and fibrin 7. All the cases were treated with prednisone and only 4 cases were combined with immunosuppressant, azathioprine without benfit.

Periodic alternating nystagmus(PAN) is a form of spontaneous nystagmus with a specific pattern. It may be of congenital origin in many cases, and may be related to vestibulo-cerebellar system disease. It usually causes not only many ophthalmic problems such as decreased vision but also neurologic symptoms such as ataxic gait. So, ophthalmologist must perform both ophthalmic and neurologic examinations. Nystagmus can be treated with muscle relaxant. We report our experience about 30-year-old woman who complained of involuntary ocular movement and ataxic gait, and were diagnosed as PAN associated with Chiari-1 malformation and syringomyelia through electronystagmography and brain MRF.

PURPOSE: To evaluate the change of accommodation-convergence parameters after implantation of Artisan phakic intraocular lens (PIOL). METHODS: Prospective study for the patients with the Artisan PIOL implantation was performed. A total of 37 patients (3 males and 34 females) enrolled the study. Preoperatively, convergence amplitude, the stimulus accommodative convergence per unit of accommodation (AC/A) ratio and the near point of convergence (NPC) were evaluated. After the Artisan PIOL implantation, the identical evaluations were repeated at 1 week, 1, 3, and 6 months after the surgery. RESULTS: Mean age was 24.3 +/- 4.8 years old, and preoperative refractive error was -8.92 +/- 4.13 diopters (D). After the implantation, mean refractive errors significantly decreased to within +/-1.00 D, and noticeable complications were not found. The convergence amplitude and the stimulus AC/A ratio increased 1 month after the surgery, but progressively stabilized afterward to near preoperative values. NPC didn't show any significant change over follow-up period up to 6 months. CONCLUSIONS: These results regarding implantation of the Artisan PIOL revealed the increase of accommodation-convergence relationship within first 1 month after the surgery, but progressive stabilization was noted during follow-up periods.

BACKGROUND: It is reported that many types of psychiatric disorders, including anxiety disorder, are related with abnormal brain wave activity, and neurofeedback is associated with clinical improvement in generalized anxiety, OCD, phobic disorder, and PTSD. But in panic disorder, previous studies with neurofeedback are very lacking. Therefore, in this study, the author applied neurofeedback to patients with panic disorder, refractory to cognitive-behavioral therapy and medication. METHODS: From March 2 to May 15 in 2005, six patients with a panic disorder had received 20 sessions of neurofeedback training. The author evaluated the treatment effect by using the alteration of K-APPQ score, the frequency of panic attack, medication and individual handicap. RESULTS: All 6 patients completed 20 sessions of neurofeedback training. At the end, the score of total APPQ, agoraphobia, and interoceptive fear was decreased (P= 0.028) and the frequency of panic attack, medication, and individual handicap was also decreased. CONCLUSION: Neurofeedback training was successful in reducing panic symptom severity, frequency and individual handicap. A controlled study on a larger population is strongly recommended.

Objectives: This study analyzed a large outbreak of coronavirus disease 2019 (COVID-19) that occurred during a high school field trip in the Jeonbuk region and aimed to identify risk factors for COVID-19 infection, with the goal of preventing such outbreaks in the future. Methods: A retrospective cohort study of 737 participants, including 668 students and 69 staff at High School A, was designed to describe the epidemiological characteristics of this large COVID-19 outbreak. Logistic regression analysis was performed to calculate relative risks (odds ratios [ORs]) and 95% confidence intervals (CIs). Results: There were 190 confirmed cases (174 students, 16 staff), with an attack rate of 25.8%. Small outbreaks were decreasing before the field trip, but this trend reversed after the trip, leading to larger outbreaks. Logistic regression showed an OR of 2.39 (95% CI, 1.66–3.43; p<0.05) for COVID-19 infection among field trip participants. Among them, 11th graders had an OR of 2.32 (95% CI, 1.53–3.52; p<0.05) compared to 10th graders, while no significant risk difference was found within same-grade teams. Conclusion There was a high risk for COVID-19 transmission during extracurricular activities with a large number of participants, such as field trips, even after the nationwide Omicron variant epidemic subsided. Even when students are separated into teams and follow different routes, it is challenging to design routes that entirely prevent contact between teams. Thus, programs should be designed carefully, and students with symptoms should be identified before and during the program to isolate them promptly.

OBJECTIVES: The purpose of this study was to evaluate the effect of periodontal health promotion and oral hygiene in children using a vibrating toothbrush. METHODS: Forty-seven volunteers aged between 7-15 years participated in this study at local care centers from January to February 2013. A vibratory toothbrush for children was designed with the bristles operating on a self-vibration system that separated the head-neck part of the toothbrush from the handle. The toothbrush was designed with the aim of massaging the gingiva and reducing gingival inflammation. The papillary marginal attachment (PMA) index and O'Leary plaque index were measured by oral examinations before and at 4 weeks after brushing with the vibrating toothbrush. RESULTS: The PMA index and O'Leary plaque index were reduced from 39.20 to 25.42 (P<0.001) and from 5.56 to 2.78 (P<0.001), respectively. CONCLUSIONS: These results suggested that vibrating toothbrushes designed for children can be helpful in promoting gingival health and improving oral hygiene.

PURPOSE: In this study, we examined the incidence of osteoporosis and the related factors in distal radius fractures (DRFs) caused by minor trauma, as well as the necessity of a bone mineral density (BMD) measurement. MATERIALS AND METHODS: One hundred and sixty patients, who had their BMD measured after DRFs caused by minor trauma, were enrolled in this study. The BMD was measured at the lumbar spine and proximal femur by dual energy X-ray absorptiometry. The BMD values were categorized as normal, osteopenia and osteoporosis by the WHO T-score criteria and each incidence was investigated. The BMD values were compared with the change of age and among age-based groups. The relationship between the BMD and factors such as age, gender, body mass index, or AO classifi cation were assessed. The agreement in BMD values between the lumbar spine and proximal femur was evaluated. RESULTS: The incidence of osteoporosis in DFRs by minor trauma was 74%. The minimum BMD in the DRFs had a negative correlation with age. Signifi cant differences in the BMD values were observed between the groups divided by the 10-year-old intervals (p<0.001) but the differences in the groups aged over 60 were signifi cantly lower than those under the age of 60 (p<0.001). There was a close relationship between the BMD values and the patients' age (p<0.001), but not between the BMD values and the AO classifi cation (p=0.670). The simple agreement between the lumbar spine and proximal femur was 0.619, but the Kappa index was 0.305. CONCLUSION: Because the incidence of osteoporosis in the DRFs by minor trauma is relatively high, it is necessary to measure the BMD. The BMD should be measured at more than two body parts to ensure that osteoporosis accompanied by DRFs is not missed.

The term 'ancient' schwannoma was proposed for a group of neural tumors showing degenerative changes and marked nuclear atypia. The findings from abdominal ultrasound and computed tomography, in a patient with a retroperitoneal ancient schwannoma, are presented, and the histological features of this unusual type of tumor are reviewed. The presence of a large, well-delineated complex cystic mass in the deep soft tissues should raise the possibility of an ancient schwannoma. The treatment of choice for an ancient schwannoma is complete excision. It is important to recognize these tumors as benign, with excellent prognosis, so as to avoid unnecessary radical surgery. A recurrence, or persistence, seems to be associated with incomplete resection, which occurred in 10% of the reported cases.

An estrogen producing adrenocortical carcinoma is a rare, highly malignant tumor. Fewer than 100 cases of feminizing adrenocortical carcinomas in men have been reported. These tumors are usually large in size and show high levels of serum total estrogen and estradiol. Recently, two cases of estrogen producing adrenocortical carcinoma were experienced by our selves during in year. A unilateral adrenalectomy, with mass excision, was performed in both patients, with an ipsilateral nephrectomy performed in just one. Mitotane or cisplatin based adjuvant chemotherapy was also performed.

OBJECTIVE: The purpose of the study was to evaluate the safety and efficacy of tension-free vaginal tape (TVT) placement for surgical treatment of stress urinary incontinence (SUI) in women. METHODS: A retrospective study of 38 cases with SUI underwent the TVT procedure underlying local anesthesia at Daedong and Sewoong Hospital from March 2000 to December 2000, followed up more than six months who included in the study. RESULT: Operation times ranged from 20 to 53 minutes with a mean of 37.5 minutes. The mean blood loss was 90 mL. One major complication was encountered -bladder perforation (2.5%) and urinary retention was developed in 4 cases (10.5%). Length of hospital stay ranged from 0.8 to 11.3 days with a mean of 1.8 days. On postoperative follow-up from 6.1 to 17.5 months, thirty-three patients (87%) were cured, four (10.5%) were significantly improved and one was failed (2.5%). CONCLUSION: Althouth the follow-up period was short, the TVT procedure seemed to be a safe and effective method for the treatment of stress urinary incontience.
