PURPOSE: We present the results of visual evoked potential (VEP), electroretinography (ERG), and electrooculography (EOG) in normal subjects using the Mon-pack 3 system (Metrovision). METHODS: VEP, ERG, and EOG were obtained in 92 normal eyes. The measurements followed the International Society for Clinical Electrophysiology of Vision (ISCEV) standardization protocol. In VEP, the standard electrode was placed on the forehead and the active electrode was attached on the occiput. In ERG, a 20-minute dark adaptation was performed after mydriasis, and an ERG-jet electrode was used. EOG was measured by attaching an electrode to each medial canthal skin. Each latent period and electric potential was measured with average, standard deviation, median, and 95% confidencenterval (95% CI). RESULTS: The mean P100 latency in pattern VEP was 104.36 ms, and P100 latency in flash VEP was 116.71 ms. For the maximal ERG response, the implicit times of a and b waves were 22.65 ms and 44.58 ms, respectively and the amplitude of a and b waves were 274.09 microv and 489.52 microv, respectively. For the ERG cone response, the implicit time of a and b waves were 18.21 ms and 33.40 ms, respectively, and the amplitude of a and b waves were 35.87 microv and 104.42 microv, respectively. The mean ERG oscillitatory potential was 285.53 microv. The average EOG Arden ratio was 2.54. CONCLUSIONS: VEP, ERG, and EOG results from normal subjects using the Mon-pack 3 system can be applied to the diagnosis of retina and optic nerve disease and basic research.

Purpose : To evaluate the short term result of the tension-free vaginal tape (TVT) procedure in conjunction with vaginal hysterectomy in patients with concurrent stress incontinence and gynecological diseases. Materials and Methods: All patients (32 women) underwent the TVT procedure in conjunction with vaginal hysterectomy between June 2001 and April 2003. Preoperative histories, subjective questionnaires of the degree of incontinence, physical examinations, one hour pad tests and full urodynamic testing were evaluated. The postoperative clinical outcomes, patient satisfaction and complications were checked after 3-months. Results: Thirty-two women who met the study criteria were identified. The mean follow-up time, parity, age, operating time and length of hospital stay were 9.2 months, ranging from 3 to 18 months, 2.6, ranging from 1 to 5, 52.5 years, ranging from 40 to 68, 73 minutes, ranging from 55 to 122 minutes and 4.3 days, ranging from 3 to 9 days, respectively. From the questionnaires, 22 patients were found to be mildly incontinent, 7 moderately incontinent and 3 severely incontinent. All patients were cured of gynecological disease. All cases of mild, 5 of moderate and 2 of severe incontinence were cured. The three remaining patients improved. Twenty-eight patients were satisfied after the operation and 1 had intraoperative bladder perforation. Conclusions: The TVT procedure in conjunction with a vaginal hysterectomy for stress incontinence with other gynecologic disease is considered safe and efficacious, although a longer follow-up will be necessary to determine the long term effect.

PURPOSE: This study was done to compare clinical nurses' knowledge and visual differentiation diagnostic ability for the pressure ulcer classification system (PUCS) and incontinence-associated dermatitis (IAD). METHODS: A convenience sample of 602 nurses took the pressure ulcer classification system and incontinence-associated dermatitis knowledge test (PUCS & IAD KT) and completed the visual differentiation tool (VDT), consisting of 21 photographs with clinical information. RESULTS: The overall mean score for correct answers was 14.5 (+/-3.2) in PUCS & IAD KT and 11.15 (+/-4.9) in PUCS & IAD VDT. Incorrect responses were most common for statements related to stage III, IAD for PUCS & IAD KT, and suspected deep tissue injury (SDTI), unstageable, and stage III for PUCS & IAD VDT. Significant correlations were found between PUCS & IAD KT and VDT (r=.48, p<.001). Factors affecting scores for PUCS & IAD VDT were PUCS & IAD KT, frequency of pressure ulcer, IAD management and participation in wound care education programs. CONCLUSION: Results indicate that nurses have an overall understanding of PUCS & IAD, but low visual differentiation ability regarding stage III, SDTI, and unstageable ulcers. Continuing education is needed to further improve knowledge and visual differentiation ability for PUCS & IAD.

Traumatic optic neuropathy (TON) is an important cause of severe visual loss after blunt or penetrating head and facial trauma. High-dose steroids and surgical interventions have been applied in the indirect TON. However, there is no convincing evidence that results of the treatment have any strong benefits in terms of improvement of visual acuity. Nevertheless, surgical decompression should be considered in the case of a direct bony compression to the optic nerve and a progressive visual loss in indirect TON. Neurosurgeon should be aware the surgical indication, optimal timing and relevant technique for the optic canal (OC) decompression. In this review article, we will focus on the surgical approaches to the OC and how to decompress it.

Intramural pregnancy implanting in the previous cesarean section scar is one of the rarest form of an ectopic pregnancy and probably the most dangerous form because of its risk of rupture and hemorrhage. For its sonographic diagnosis, the gestational sac should be in the anterior wall of uterine isthmic portion, there should be no myometrium between bladder and gestational sac, and it should be verified that uterine cavity and cervix should be isolated from gestational sac. For young patients who wish to maintain their fertility, an earlier diagnosis and more conservative treatment are desirable. We have recently experienced a case of intramural pregnancy implanting in the scar of cesarean section, treated with systemic methotrexate injection. So, we report this case with a brief review of the literature.

Retroperitoneal Schwannoma is relatively rare and benign tumor originating from Schwann cell. Schwannomas arising in the retroperitoneum are infrequently reported. The majority of Schwannoma is found incidentally and misdiagnosed for other benign conditions both clinically and radiologically. We report a case of a benign retroperitoneal pelvic Schwannoma which was preoperatively misdiagnosed as an ovarian tumor with brief review of literatures.

Purpose: This study aimed to evaluate the performance of transfer learning in a deep convolutional neural network for classifying implant fixtures. Materials and Methods: Periapical radiographs of implant fixtures obtained using the Superline (Dentium Co. Ltd., Seoul, Korea), TS III (Osstem Implant Co. Ltd., Seoul, Korea), and Bone Level Implant (Institut Straumann AG, Basel, Switzerland) systems were selected from patients who underwent dental implant treatment. All 355 implant fixtures comprised the total dataset and were annotated with the name of the system. The total dataset was split into a training dataset and a test dataset at a ratio of 8 to 2, respectively. YOLOv3 (You Only Look Once version 3, available at https://pjreddie.com/darknet/yolo/), a deep convolutional neural network that has been pretrained with a large image dataset of objects, was used to train the model to classify fixtures in periapical images, in a process called transfer learning. This network was trained with the training dataset for 100, 200, and 300 epochs. Using the test dataset, the performance of the network was evaluated in terms of sensitivity, specificity, and accuracy. Results: When YOLOv3 was trained for 200 epochs, the sensitivity, specificity, accuracy, and confidence score were the highest for all systems, with overall results of 94.4%, 97.9%, 96.7%, and 0.75, respectively. The network showed the best performance in classifying Bone Level Implant fixtures, with 100.0% sensitivity, specificity, and accuracy. Conclusion Through transfer learning, high performance could be achieved with YOLOv3, even using a small amount of data.

Meningioma although quite common in adults, are extremely rare in infant. Only 25cases of meningioma in patients younger than 1 year old have been reported in the world literature. The authors report a case of meningioma associated wth multiple cysts in a 6-month-old infant.
