24-hour ambulatory ECG monitoring has been examined for the evaluation of heart rate and longest pause in 34 patients with chronic atrial fibrillation (20 patients treated with digoxin and 14 patients without treatment). Following results were obtained: 1. In 34 patients, the mean of average heart rates was 75.7±13.8/minute, fastest heart rates 148.0±32.4/minute, slowest heart rates 48.1±8.4/minute, difference between fastest and slowest heart rates in individual patients 99.9±29.0/minute and longest pauses 2.95±1.06seconds. The longest pauses of more than 4.0 seconds occurred in 4 of the 34 patients and made an exception of comparison groups. 2. In 27 of the 34 patients, ventricular premature contractures were developed and in 11 of 27, mainly occurred less than 100/24 hours and aberrant conduction occurred in all patients. 3. In 20 patients treated with digoxin (0.25 mg/day), the mean of average heart rates was 78.4±13.7/minute, fastest heart rates 152.5±33.1/minute, slowest heart rates 48.9±8.5/minute, difference between fastest and slowest heart rates in individual patients 103.6±31.7/minute and longest pauses 2.55±0.50 seconds. 4. In 10 patients without treatment, the mean of average heart rates was 78.0±10.7/minute, fastest heart rates 154.5±26.8/minute, slowest heart rates 50.6±7.1/minute, difference between fastest and slowest heart rates in individual patients 103.9±22.2/minute and longest pauses 2.66±0.39 seconds. 5. The difference of heart rates and longest pauses between patients with treatment and without treatment were statistically not significant (P>0.05). In summary, authors seemed to consider that 24-hour ambulatory ECG was useful and safe method for clinical evaluation of patients with chronic atrial fibrillation.

Unilateral renal agenesis associated with genito-urinary disease was found in 2 siblings of a single family. There are a few reports of familial unilateral renal agenesis. Bilateral renal agenesis is a fetal condition and unilateral renal agenesis or hypoplasia is usually asymptomatic, so investigations for renal anomalies have not been frequently undertaken in healthy members of families in which bilateral agenesis has occurred. The present report suggests that unilateral renal agenesis could occur as a manifestation of a genetic disorder.

BACKGROUND: Complex regional pain syndrome (CRPS) is categorized into sympathetically maintained pain (SMP) and sympathetically independent pain (SIP). Spinal cord stimulation (SCS) is a promising approach in the treatment of severely disabling CRPS. Patients with good responses to sympathetic block before SCS are more likely to have positive responses to SCS than those with negative responses. This study compared the effects of SCS in patients with CRPS, of SMP and SIP categories. METHODS: This was a retrospective study of 16 patients (SMP 8, SIP 8) with CRPS who had undergone trials of SCS. Eleven of the patients had permanent SCS device implants, and the pain relief levels at 1 and 6 months were recorded. RESULTS: Sixteen patients with severe, incapacitating, and therapy-resistant CRPS underwent SCS trials. Five patients (SMP 3, SIP 2) had poor pain relief during the trial despite adequate coverage. The remaining 11 patients (SMP 5, SIP 6) had permanent electrode implantation performed under local anesthesia and experienced good pain relief. The difference in VAS reduction was not significant between the two groups at the 1-month follow-up (P = 0.325) and the 6-month follow-up (P = 0.779). CONCLUSIONS: There were no statistically significant differences in VAS pain scores between the two groups. The favorable outcome in all 11 patients with only minor remaining symptoms or without remaining symptoms or severe recurrences suggests that SCS is an efficient treatment in SMP and SIP.

PURPOSE: The purpose of the study was to compare dietary habits, perception, and consumption frequency of fast foods between part-time working youths at fast food restaurants and those at other food-related services. METHODS: The study subjects were part-time working youths in 13 fast food restaurants (n = 118) and in 25 other places including bakeries, cafes, convenience stores, and other restaurants (n = 115) in Cheongju. Demographic characteristics, dietary habits, perception regarding fast foods, and consumption frequencies of food groups and fast foods were assessed using a self-administered questionnaire. RESULTS: Female youths working at fast food restaurants had unhealthier dietary habits, such as meal skipping and night snacking compared to those working at other places. Consumption frequencies of fruits in males and beans/bean products in females working at fast food restaurants were significantly lower than those working at other places. Perception score on fast foods was significantly lower in males working at fast food restaurants than in males working at other places. However, the consumption frequencies of hamburgers, pizzas, and a total of six fast foods among both males and females working at fast food restaurants were significantly higher than those working at other places after adjusting for confounding variables including age, status, type of residence, allowance, alcohol, smoking, working hours, and hourly pay. CONCLUSION: Part-time working youths at fast food restaurants had worse dietary habits, such as meal skipping and night snacking, and consumed fast foods more frequently than those working at other places. Interventions for part-time working youths at fast food restaurants may be needed in order to reduce fast food consumption and increase the intake of fruits and vegetables.

BACKGROUND: Neuroplasty using a Racz catheter or epiduroscope and percutaneous endoscopic laser discectomy are performed as treatment for chronic refractory low back and/or lower extremity pain, but they are limited in that they cannot completely remove the causing pathology. Lately, epiduroscopic laser neural decompression (ELND) has been receiving attention as an alternative treatment, but there are insufficient reports of results. Hence we aimed to investigate and report the data in our hospital. METHODS: Seventy-seven patients were selected who had received ELND via the anterior and posterior epidural approach through the pain clinic in our hospital from March 2011 to July 2012. Their medical records including age, diagnosis, epiduroscopic findings and degree of symptom relief were investigated. The degree of symptom relief following the procedure was categorized into 5 stages of very good (5), good (4), no change (3), bad (2), and very bad (1) at 2 weeks and 1 month after the procedure. RESULTS: The subjects were 30 males and 47 females. Mean age was 54.6 for males and 59.6 for females, so the overall mean age was 58.1 years old, with the youngest being 23 and the oldest 88 years old. In epiduroscopic images of all patients, more than one situation of herniated disc, fibrous tissue and adhesion, or inflammation was observed. Sixty-seven patients (87.0%) showed symptom relief 2 weeks after the procedure and 63 patients (81.8%) showed relief after 1 month. CONCLUSIONS: ELND is considered to be an effective treatment alternative for chronic refractory low back and/or lower extremity pain, including lumbar disc herniation, lumbar spinal stenosis, and failed back surgery syndrome which cannot be alleviated with existing non-invasive conservative treatment.

Epiduroscopy is very useful in the treatment of not only low back pain caused by failed back surgery syndrome, epidural scar or herniated disc but also by chronic refractory low back pain which does not respond to interventional conservative treatment including fluoroscopically-directed epidural steroid injections and percutaneous adhesiolysis. Because cauterization using a laser fiber has become recently available, a wider opening is required to enter into the sacral canal in the case of epiduroscopic laser neural decompression (ELND). However, in a few patients, it is difficult to insert a device into the epidural space due to stenosis around the opening, and there is no alternative method. Herein, we report a case where a hiatus rasp specially designed for such patients was used to perform the operation.

Background: To report the long-term clinical and radiologic results of impaction bone grafting and standard cemented polished stem for femoral revision arthroplasty in patients with extensive bone deficiency. Methods: We retrospectively reviewed 47 hips that underwent femoral revision hip arthroplasty using an impaction-morselized allograft with a standard cemented polished stem. The average age at the time of revision hip arthroplasty was 55 years (range, 39–75 years). The modified Harris hip score (HHS) was used for clinical evaluation. The radiologic evaluation focused on stem subsidence, stem position, progressive radiolucent lines, bone remodeling, and the incorporation of allografts. Results: The modified HHS improved from an average of 55.04 (range, 25–79.5) preoperatively to 90.1 (range, 81–93.2) at the last follow-up. The mean follow-up duration was 13.5 years (10.9–17.8 years). The radiographic analysis revealed stable stems.Femoral stems showed an average subsidence of 3.2 mm (range, 2–8 mm) in the cement mantle. However, there was no mechanical failure or subsidence of the cement mantle in the femurs. The stem position was neutral or varus less than 5°. No progressive radiolucent line or osteolysis was observed. Evidence of cortical and trabecular remodeling was observed in all cases. There were four cases of intraoperative cracks and four cases of distal femur splitting. Conclusions Initial stem stability using impaction bone grafting and a standard cemented polished stem in femoral revision arthroplasty resulted in good outcome. Delicate impaction grafting techniques and intraoperative crack and splitting fixation are the points that need attention for successful long-term results.
