Although the spontaneous disappearance or decrease in size of a herniated disc is well known, that of a large extruded disc has rarely been reported. This paper reports a case of a spontaneous regression of a large lumbar disc extrusion. The disc regressed spontaneously with clinical improvement and was documented on a follow up MRI study 6 months later. The literature is reviewed and the possible mechanisms of spontaneous disc regression are discussed.

Majority of the eyes with subfoveal neovascular membrane lose the central vision. We observed two patients who regained significant central vision as the result of the involution of subfoveal neovascularization. On follow-up fundus examination, the subretinal lesions revealed grayish neovascular membranes stained with fluorescein, but did not show the fluid leakage. And subretinal hemorrhage and subretinal fluid were gradually resolved. We assumed that functioning retinal pigment epithelium within the macula and young age were the important factors of the spontaneous improvement of visual outcome.

There is still debate over which method of the surgery is the most appropriate for the treatment of scaphocephalic infants. In addition, change in psychomotor development following these procedures is a very complex issue that has not yet been resolved. In this paper, the authors describe a surgical technique for immediate spontaneous shape correction of infantile scaphocephaly. There were significant differences between pre- and postoperative cephalic index. We also describe an improvement in the developmental quotient following surgery. Therefore, this expantile zigzag craniectomy should be recommended to correct for isolated sagittal craniosynostosis in infants.

Purpose: The majority of patients with radiculopathy caused by a herniated nucleus pulposus (HNP) heal spontaneously without surgery. The aim of this report is to describe the spontaneous regression of lumbar disc herniation and the results of clinical follow-up. Methods: Three patients with radiating low back pain presented with an extruded intervertebral disc on magnetic resonance imaging (MRI). We performed follow-up with conservative treatment (epidural injection, medication, physical therapy, exercise) and clinical assessments on the 6th, 10th and 22nd months. Results: The extruded intervertebral disc almost complete regressed, and correlated with clinical improvement and follow-up MRI. Conclusion: Conservative treatment can be an effective approach for a herniated lumbar discs if no neurological deficits are present.

Objectives: This paper is to report a spontaneous pregnancy with low AMH level and thin endometrium infertility after Korean medical treatments.Methods: A 38-year old patient who had low AMH level, thin endometrium, sleep disturbance and anxiety happened after anorectal cancer surgery was treated by korean medicine such as herb medications per day for 6 months. And we observed the effects of treatments by improvement of symptoms checking endometrium ultrasonography.Results: After treatments, Symptoms of anxiety and sleep disturbance were improved. The number of ovarian follicle and endometrium thickness were upgraded during artificial pregnancy trials. Finally the patient was a spontaneous pregnancy after failures of one intrauterine insemination and one in vitro fertilization trial.Conclusions: This case shows that the korean medicine has effective option for a patient with low AMH level and thin endometrium infertility. Further ultrasonography would be valid measurements to check the effectiveness of oriental treatments as well as symptoms.

Background : The purpose for this study is to develop a critical pathway of bullectomy for spontaneous pneumothorax patients. Methods : For this study a conceptual framework of critical pathway was developed through a review of the literature including five critical pathways which are currently being used in USA, and opinions of the critical pathway development team members at Y university hospital. In order to identify the service contents required by these patients and to draw up a preliminary critical pathway, 33 cases of medical records of patients who had received bullectomy for spontaneous pneumothorax between September, 2000 to August, 2001 at the Respiratory Center of Y university hospital in Seoul was analyzed. Results : In order to test the clinical validity of the preliminary critical pathway, it was applied to ten patients who had received bullectomy for spontaneous pneumothorax from October, 2001 to December, 2001. The average discharge day was 4.89th post operation day, six patients discharged on the fourth post operation day which was the expected day, one patients discharged one day earlier than the expected day, one patient discharged three days later than the expected day, and one patient discharged six days later than the expected day. There were variances between the critical pathway and the actual practice. The variances came from tests, medications, and treatments. One item that showed variance in clinical applications was complemented, and three items were decided not to be corrected for the final determination of the critical pathway. Conclusion : This critical pathway is applicable to the care of patients with bullectomy for spontaneous pneumothorax, but it needs more clinical applications to grasp varied variances.

Spontaneous intracranial hypotension (SIH) is believed to be a benign disease. However, numerous studies have reported serious complications related to SIH, including subdural hematoma. In this case report, a 54-year-old male patient visited the emergency room with orthostatic headache. A brain magnetic resonance imaging (MRI) study showed diffuse mild thickening and enhancement of pachymeninges, with a suspicious minimal amount of subdural fluid collected in the left posterior parietal area. His orthostatic headache showed no improvement with conservative treatment; but his pain was almost completely relieved after two trials of cervical epidural blood patch. On the 74th day after the onset of his pain, the patient showed a drowsy mental status and slurred speech when he visited the pain clinic. Brain computerized tomography indicated a left subdural hemorrhage, and he underwent emergency operation to drain the SDH. In conclusion, pain clinicians should pay attention to abrupt changes in mental status as well as continuous headache, for the early diagnosis of SDH in SIH patients.

The purpose of this study was to determine the effects of associative drawing task in a Korean bilingual aphasic. The subject is a 41-year old male and lived and was educated in the United States for over 25 years(from the age of 14 through 39). His former occupation was a psychiatrist. He has had a massive lesion in the occipital lobe. This study focused on improving his spontaneous language performances by associative drawing task. The associative drawing task along with spontaneous speech is to help the subject's cognition. The ten target words in this treatment were familiar words and could be drawn easily. The results were that the associative drawing task was effective on improving the patient's drawing ability-writing ability in English only-and naming performance both in English and Korean. However, the patient's writing ability in Korean did not show any improvement.

Recent advances in deep learning for speech and visual recognition have accelerated the development of multimodal speech recognition, yielding many innovative results. We introduce a Korean audiovisual speech recognition corpus. This dataset comprises approximately 150 h of manually transcribed and annotated audiovisual data supplemented with additional 2000 h of untranscribed videos collected from YouTube under the Creative Commons License. The dataset is intended to be freely accessible for unrestricted research purposes. Along with the corpus, we propose an open-source framework for automatic speech recognition (ASR) and audiovisual speech recognition (AVSR). We validate the effectiveness of the corpus with evaluations using state-of-the-art ASR and AVSR techniques, capitalizing on both pretrained models and fine-tuning processes. After fine-tuning, ASR and AVSR achieve character error rates of 11.1% and 18.9%, respectively. This error difference highlights the need for improvement in AVSR techniques. We expect that our corpus will be an instrumental resource to support improvements in AVSR.
