BACKGROUND: A systematic literature review of interspinous dynamic stabilization, including DIAM, Wallis, Coflex, and X-STOP, was conducted to assess its safety and efficacy. METHODS: The search was done in Korean and English, by using eight domestic databases which included KoreaMed and international databases, such as Ovid Medline, Embase, and the Cochrane Library. A total of 306 articles were identified, but the animal studies, preclinical studies, and studies that reported the same results were excluded. As a result, a total of 286 articles were excluded and the remaining 20 were included in the final assessment. Two assessors independently extracted data from these articles using predetermined selection criteria. Qualities of the articles included were assessed using Scottish Intercollegiate Guidelines Network (SIGN). RESULTS: The complication rate of interspinous dynamic stabilization has been reported to be 0% to 32.3% in 3- to 41-month follow-up studies. The complication rate of combined interspinous dynamic stabilization and decompression treatment (32.3%) was greater than that of decompression alone (6.5%), but no complication that significantly affected treatment results was found. Interspinous dynamic stabilization produced slightly better clinical outcomes than conservative treatments for spinal stenosis. Good outcomes were also obtained in single-group studies. No significant difference in treatment outcomes was found, and the studies compared interspinous dynamic stabilization with decompression or fusion alone. CONCLUSIONS: No particular problem was found regarding the safety of the technique. Its clinical outcomes were similar to those of conventional techniques, and no additional clinical advantage could be attributed to interspinous dynamic stabilization. However, few studies have been conducted on the long-term efficacy of interspinous dynamic stabilization. Thus, the authors suggest further clinical studies be conducted to validate the theoretical advantages and clinical efficacy of this technique.

An anomalous left coronary artery from the pulmonary artery(Bland-White-Garland syndrome) is a rare congenital malformation and sometimes fatal. It is caused by an abberant endothelial budding from or an anomalous division of the truncus arteriosus. Echocardiography (transthoracic and transesophageal) and angiographical imaging are essential for the diagnosis of this anomaly. Corrective Surgery is recommended due to its fatal natural course. A case was diagnosed in a 45-year-old man who presented with intermittent palpitation. This patient was successfully treated with closure of anomalous left coronary artery orifice combined with right saphenous vein graft anastomosis.

A patient, 59 years old male, with paroxysmal AV reentrant tachycardia utilizing a concealed left lateral accessory pathway with long VA conduction time is presented. During tachycardia P waves were negative in leads I, aVL, and V6 and positive in leads aVR and V1. The R-P/P-R ratio was 1.6. Radiofrequency catheter ablation was successful to interrupt the VA conduction through the accessory pathway.

The implatnation of malignant cells along the needle tract is an extremely rare complication after a percutaneous fine-needle aspiration biopsy(FNAB). However, it is very serious and may result in a change in the prognosis of lung cancer, especially in the curable early stage(T1-2,N0,M0). Recently, we experienced two cases of such complications. A 43 years old female underwent a fine needle aspiration biopsy and a right middle lobectomy with adjuvant chemotherapy due to an adenocarcinoma(T2N0M0). Two years later, a new tumor developed at the site of the needle aspiration biopsy. It had the same pathological findings as the previous lung cancer. Therefore, it was concluded to be an implantation metastasis, and she was treated successfully by a right pneumonectomy and a resection of the chest wall mall with adjuvant radiotherapy. In another case, a 62 years old man was diagnosed with squamous cell lung cancer by a fine needle aspiration biopsy and underwent a right upper lobectomy(T2N0M0) with adjuvant chemotherapy. eight months later, a protruding chest wall mass developed at the aspiration site. It showed the same pathological findings as the previous lung cancer. Consequently, a total excision of the mass with adjuvant radiotherapy was done. Two years after the second operation, although the right lung was intace a metachronous squamous cell lung cancer was found at the left lower lobe. The two patients were still alive 15 and 37 months after thenresection of the chest wall mass, respectively.

STUDY DESIGN: This is a retrospective study. OBJECTIVES: To analyze the clinical outcomes of simple discectomy in patients with recurrent lumbar disc herniation. SUMMARY OF LITERATURE REVIEW: There are two methods of studying the treatment of recurrent lumbar disc herniation. The first type of study considers fusion for the prevention of complications such as postoperative lumbar segmental instability and persistent back pain. The second type of study assumes that simple discectomy without fusion is sufficient in the surgical management of recurrent lumbar disc herniation. MATERIALS AND METHODS: Sixteen patients who underwent simple discectomy due to recurrent lumbar disc herniation were followed up over 3 years. The mean age was 52.8 years (38-68 years). The mean follow-up period was 75.4 months (36-144 months). VAS scores for back pain and radiating lower leg pain were each compared pre- and post-operatively. The Oswestry Disability Index (ODI) was used to analyze the clinical outcome. A modified MacNab's outcome was used to evaluate patient satisfaction. Subjective survey data in a Delphi checklist was reviewed to verify clinical lumbar instability. RESULTS: The mean back pain VAS score showed 87.5% improvement (p<0.001). The mean lower leg VAS score showed 89% improvement (p<0.001). The mean preoperative ODI score was 29.9, and the mean score checked at the last follow up was 3.5. It thus showed 88.3% improvement (p<0.001). Excellent or good satisfaction was reported by fourteen patients (87.5%), and clinical lumbar instability was identified in one patient (6.3%). CONCLUSIONS: Simple discectomy without fusion is one of treatment option for recurrent disc herniation without instability.

Plasma renin activity (ORA) was determined by radioimmunoassay in 55 normal controls and 121 hypertensive patients in basal state and after double stimulation with furosemide administration and upright posture of 4 hrs. The results were obtained as follows, 1) Mean value of PRA of normal control was 2.2+/-1.41ng/ml/hr in basal state and 2.9+/-1.39ng/ml/hr after double stimulation, respectively. The latter was elevated significantly as compaired to the former. 2) PRA in males was significantly higher than in females, and PRA tend to be decreased as age become old. 3) Normal value of PRA after double stimulation was ranged from 1.0 to 5.0 ng/ml/hr. Of total 121 hypertensive patients(55 males and 66 females), PRA was low in 33 cases(27.3%), normal in 77 cases (63.6%), and high in 11 cases(9.1%). 4) Of 55 male hypertensive patients, PRA was low in 13 cases(23.6%), normal in 35 cases (63.7%), and high in 7 cases(12.7%). Of 66 female hypertensive patients,, PRA was low in 20 cases (30.3%), normal in 42 cases(63.6%), and high in 4 cases(6.1%). High renin group was observed more frequently in male hypertensive patients than in female hypertensive patients, while low renin group more frequently in famale than in male patients. 5) Low renin group was observed more frequently in older age group than in younger age group, while high renin group more frequently in younger age than in older age group.

OBJECTIVE: Miniscrew-assisted rapid palatal expansion (MARPE) is a means for expanding the basal bone without surgical intervention in young adults. Here, we assessed the differences in dental, alveolar, and skeletal measurements taken before (T0), immediately after (T1), and 1 year after (T2) MARPE. METHODS: Twenty-four patients (mean age, 21.6 years) who had undergone MARPE and cone-beam computed tomography at T0, T1, and T2 were included. Changes in the following parameters were compared using paired t-tests: intercusp, interapex, alveolar, nasal floor, and nasal cavity widths; inclination of the first molar (M1) and its alveolus; and thickness and height of the alveolar bone. A linear mixed-effects model was used to determine variables that affected periodontal changes in the M1. RESULTS: MARPE produced significant increases in most measurements during T0–T2, despite relapse of some measurements during T1–T2. The alveolar thickness decreased on the buccal side, but increased on the palatal side. The alveolar crest level at the first premolar moved apically. Changes in the thickness and height of the alveolar bone were affected by the corresponding initial values. CONCLUSIONS: MARPE can be used as an effective tool for correcting maxillomandibular transverse discrepancy, showing stable outcomes 1 year after expansion.

OBJECTIVES: To understand the importance of the serum level of Ca-125 among pelvic mass, we performed a study. METHOD: From January to December 1998, we performed the study. Before hysterectomy, we performed a blood sampling to know the serum level of Ca-125, After hysterectomy, we weighed the uterus and measured the thickness of endometrium and other histologic characteristics. RESULTS: We performed my research to 80 peoples. The relation between uterine weight and the serum level of Ca-125 is little, if ever(R2=0.0007), and the relation between the thickness of endometrium and the serum level of Ca-125 is also little, if ever(R2=0.0353). The relation between leiomyoma, the cycle of endometrium and the serum level of Ca-125 were also little, but there was a close relationship between adenomyosis and the serum level of Ca-125. CONCLUSION: There was little relationship between uterine weight and the serum level of Ca-125.
