1.Experience of Extracorporeal Shock Wave Lithotripsy (ESWL) with EDAP-LT01: A Report of 660 Cases.
Korean Journal of Urology 2001;42(5):483-488
PURPOSE: Since ESWL had been developed, many experiences of the treatments to urinary stones with various type of lithotriptors were reported. We evaluated the efficacy of EDAP-LT01 piezoelectric lithotriptor according to the size, location of the stone, number of the treatment session, adjuvant therapy and cause of failure. MATERIALS AND METHODS: We retrospectively analyzed the data of 660 cases who had been treated with ESWL. Among the patients, the renal stones were 122, the ureteral stones were 452, and combined with renal and ureteral stones were 43 cases. The mean size of stones was 13mm (range: 4-38mm). ESWL was performed to all the patients with urinary stones except complete staghorn calculi. No anesthesia was performed except in one child (5 years old). RESULTS: Overall success rate was 94.7%, and there were close correlations between the success rate and the size. The mean number of sessions was 2.4. There was no significant complication, but 35 cases were failed by ESWL monotherapy, and auxiliary procedures were done in 21 cases. Efficiency quotient was 0.59. CONCLUSIONS: The ESWL with EDAP-LT01 seems to be effective and safe to treat the urinary stones of various location and size, even compared to the lithotriptors of other type. We also propose that ESWL monotherapy with this machine is efficient for the treatment of the partial staghorn calculi and stones larger than 30mm.

Journal of Korean Academy of Community Health Nursing 2018;29(2):244-256
PURPOSE: This study tried to understand discourses of life-sustaining treatments in general daily and healthcare newspapers. METHODS: A text-network analysis was conducted using the NetMiner program. Firstly, 572 articles from 11 daily newspapers and 258 articles from 8 healthcare newspapers were collected, which were published from August 2013 to October 2016. Secondly, keywords (semantic morphemes) were extracted from the articles and rearranged by removing stop-words, refining similar words, excluding non-relevant words, and defining meaningful phrases. Finally, co-occurrence matrices of the keywords with a frequency of 30 times or higher were developed and statistical measures—indices of degree and betweenness centrality, ego-networks, and clustering—were obtained. RESULTS: In the general daily and healthcare newspapers, the top eight core keywords were common: “patients,” “death,” “LST (life-sustaining treatments),” “hospice palliative care,” “hospitals,” “family,” “opinion,” and “withdrawal.” There were also common subtopics shared by the general daily and healthcare newspapers: withdrawal of LST, hospice palliative care, National Bioethics Review Committee, and self-determination and proxy decision of patients and family. Additionally, the general daily newspapers included diverse social interest or events like well-dying, euthanasia, and the death of farmer Baek Nam-ki, whereas the healthcare newspapers discussed problems of the relevant laws, and insufficient infrastructure and low reimbursement for hospice-palliative care. CONCLUSION: The discourse that withdrawal of futile LST should be allowed according to the patient's will was consistent in the newspapers. Given that newspaper articles influence knowledge and attitudes of the public, RNs are recommended to participate actively in public communication on LST.

Vesicoureteral reflux (VUR) is common disease found in up to 70% of children who have urinary tract infection, and the various type of antireflux surgerys were used to correct the problem. Among them, Gil-Vernet antireflux technique is a useful method and it has many advantages such as procedure of simplicity, shorter operative time, and lower complication rate along with maintaining high success rate. We present six cases of vesicoureteral reflux who had been managed with Gil-Vernet antireflux technique, and review the advantages, disadvantages, complications, and usefulness of the procedure.

Intervertebral disc calcification is rare in children, and known as a spine disease of unknown cause. Since the original description by Baron in 1924, about 200 cases have been reported worldwide. This disease is usually self-limited and responds to a conservative management unless there is an evidence of disc herniation into the spinal canal with associated neural symptoms. We experienced a case of intervertebral disc calcification in a 6-year-old girl and report the clinical and radiographic findings in detail.

BACKGROUND: Memory impairment results from various neurologic disorders. Among them, the memory loss associated with stroke is called amnesic stroke. Involved regions in the amnesic stroke are medial temporal lobe, thalamus, basal forebrain, retrosplenial region, and subcortical regions. Unilateral amnesic stroke is posterior cerebral artery territory including thalamus. Isolated infarction of hippocampal region has been rarely reported because hippocampus has dual blood supply from anterior choroidal cerebral artery and posterior cerebral artery. CASE REPORT: A 61-year old male with a history of diabetes for 6 years and hypertension for 13 years, was admitted with acute memory loss occurring 6 days before admission. He could not remember the exact date, place and recent events but could remember remote events about his personal and familial affairs. Brain MRI revealed an infarction in left hippocampal region and cerebral angiography showed multiple focal stenosis and luminal irregularity on left anterior choroidal, middle cerebral, basilar and both posterior cerebral arteries. COMMENTS: We report unilateral amnesic stroke only confined to left hippocampal region with literature review.

We clinically reviewed four patients who were suffering from aseptic meningitis combined with polio-like paralysis and performed radiological. neurological and virological studies on them. Three patients were admitted to the department of Pediatrics. Asan Medical Center from March to August 1990, and one patient was admitted to the department of Pediatrics. Kangnam General Hospital. The results were as follows; 1) During the period of study, 18 patients (10.1%)out of 178 aseptic meningitis patients also suffered from hand, foot and mouth disease, and three patients (1.69%) out of 178 patients also suffered from polio-like paralysis. 2) The age of the patients who also suffered from polio-like paralysis were eight months, 22 months, 23 months and four years old respectively. Three patients were male and one patient was female. 3) Paralysis developed three to five days after aseptic meningitis infection. 4) In two cases, Magnetic Resonance Imaging (MR) showed two small cavitary lesions that means anterior horn cell necrosis in concordant with residual paralysis. Axial T1-weighted image showed decreased signal intensity and axial T2-weighted image showed increased signal intensity. In another case 20 days after onset of illness MR was performed, the transverse myelitis showed mild swelling of cornus medullaris. Follow up MR in 2 months revealed atropic change in lower thoracic spinal cord. 5) The electromyography and nerve conduction velocity test revealed acute polyradiculoneuropathy. 6) Serologic virus study were carried out in three cases for Coxsackievirus A16 and Enterovirus 71. The Enterovirus 71 antibody titer were 1:128 in two cases and 1:64 in one case. The Coxsackievirus A16 antibody titer were less than 1:4. This study showed that the causative agents for polio-like paralysis during this period seemed to be the Enterovirus 71 infection.

BACKGROUND: Many clinicians have probably used subjective, unscientific methods for dose reduction to avoid overdose in elderly patients. The aim of this study was to compare several dosing schedules of intravenous dexmedetomidine (DEX) to identify the appropriate dosing schedule within the therapeutic dose range for adequate sedation of elderly patients under spinal anesthesia. METHODS: After administration of spinal anesthesia, a loading dose of DEX was injected over 10 min in three groups with the following dosages: group A, 1.0 μg/kg of actual body weight; group B, 1.0 μg/kg of ideal body weight (IBW); and group C, 0.8 μg/kg of IBW. Then, a maintenance infusion (0.5 μg/kg of each BW/h) was administered. The bispectral index score (BIS), the time required to reach BIS 80, airway obstruction score, and the occurrence of bradycardia were recorded. RESULTS: The changes in the BIS among the groups over time were found to have statistically significant differences (P < 0.001). The times required to reach BIS 80 were 6.1 ± 5.3 min, 5.0 ± 3.6 min, and 11.0 ± 8.6 min in groups A, B, and C, respectively (P < 0.001). The airway obstruction score and the frequency of bradycardia did not have statistically significant differences among the groups. CONCLUSIONS: An initial loading dose of DEX that is 0.8 μg/kg of IBW over 10 min, followed by an infusion rate of less than 0.5 μg/kg of IBW/h may be adequate for sedation in elderly patients receiving spinal anesthesia.

Plasma cell Granuloma (PCG) is a form of idiopathic inflammatory pseudotumor (IPT). It is a rare entity character-ized by a nonneoplastic proliferation of inflammatory cells dominated by a polyclonal expansion of the plasma cells. This lesion has been discovered in many parts of the body including the central nervous system. We now report two cases of plasma cell granuloma involving the brain. The first case was a 42-year-old man who presented a right hemi-paresis. He had a lesion in the convexity of the left parietal region. The second case was a 58-year-old woman who was expressed confusion and a frontal-temporal headache. She had a lesion in the convexity of the left temporal region and mastoid bone. The diagnosis of PCG was confirmed by pathological and immunohistochemical studies revealing pre-dominant plasma cells in the affected tissues.
