PURPOSE: To evaluate the effect of acupuncture on regional cerebral blood flow (rCBF) at acupoints suggested by oriental medicine to be related to the treatment of cerebrovascular diseases. MATERIALS AND METHODS: Rest/acupuncture-stimulation Tc-99m ECD brain SPECT using a same-dose subtraction method was performed on 54 normal volunteers (34 males, 20 females, age range from 18 to 62 years) using six paradigms: acupuncture at acupoints GV. 20, GV. 26, LI. 4, ST. 36 and SP. 6. In the control study, needle location was chosen on a non-meridian focus 1 cm posterior to the right fibular head. All images were spatially normalized, and the differences between rest and acupuncture stimulation were statistically analyzed using SPM for Windows . RESULTS: Acupuncture applied at acupoint GV. 20 increased rCBF in both the anterior frontal lobes, the right frontotemporal lobes, and the left anterior temporal lobe and the left cerebellar hemisphere. Acupuncture at GV. 26 increased rCBF in the left prefrontal cortex. Acupuncture at LI. 4 increased rCBF in the left prefrontal and both the inferior frontal lobes, and the left anterior temporal lobe and the left cerebellar hemisphere. Acupuncture at ST. 36 increased rCBF in the left anterior temporal lobe, the right inferior frontal lobes, and the left cerebellum. Acupuncture at SP. 6 increased rCBF in the left inferior frontal and anterior temporal lobes. In the control stimulation, no significant rCBF increase was observed. CONCLUSION: The results demonstrated a correlation between stimulation at each acupoint with increase in rCBF to the corresponding brain areas.

A 17-year-old-boy with a bilateral incomplete cervical rib, upon abduction of his left arm at 45 degrees, had immediately begun to show symptoms of severe tingling, claudication, pallor, and weakness of his left upper extremity. These symptoms were aggravated at 90 degrees, leaving him debilitated from his work in the printing office. Transfemoral positional subclavian arteriography revealed total occlusion of the subclavian artery immediately distal to a cervical rib during 90 degrees abduction. Resection of the anterior scalene and medial aspect of the middle scalene muscles, cervical and first ribs, and arteriolysis were performed via a combined supraclavicular and infraclavi cular approach. He has returned to work as a printer with marked relief of symptoms and has remained asymptomatic over follow-up periods of 10 months.

BACKGROUND: Epidural opioids and local anesthetics provide excellent postoperative analgesia. In addition, soft tissue and intra-articular injection of bupivacaine and morphine may have a beneficial analgesic effects after total knee arthroplasty (TKA). This study was designed to assess the additional analgesic effect of combined soft tissue, and intra-articular injection of morphine and bupivacaine in patients undergoing TKA under spinal anesthesia with continuous epidural morphine and bupivacaine injection. METHODS: Forty patients aged 55 to 75 years for a TKA under spinal anesthesia were randomly divided into 2 groups. The both group of patients received a continuous epidural infusion using a two-day infusor containing morphine 5 mg in 100 ml of 0.125% bupivacaine. The experimental group of patients (n = 20) received soft tissue, and intra-articular injection containing 10 mg morphine in 100 ml bupivacaine 0.125%. The control group of patients (n = 20) received soft tissue, and intra-articular injection of 100 ml normal saline. Postoperative pain was assessed using the visual analog scale (VAS) at 1, 2, 4, 8, 12, 24, and 48 h postoperatively and side effects, such as hypotension, nausea, vomiting, pruritus, and respiratory distress were recorded. Whenever patients demanded supplemental analgesia, diclofenac sodium 75 mg was injected intramuscularly and the need for additional analgesic requirement was recorded. RESULTS: The experimental group of patients had significantly lower pain score and analgesic requirements than the control group for 2 days. There was no difference in the incidence of side effects between groups. CONCLUSIONS: Combined soft tissue, and intra-articular injection of morphine and bupivacaine with continuous epidural morphine and bupivacaine infusion reduces postoperative pain and supplementary analgesic requirements than continuous epidural morphine and bupivacaine infusion only in patients undergoing TKA.

PURPOSE: To evaluate the clinical presentation, surgical outcome of rhegmatogenous retinal detachment(RRD) after laser refractive surgery and the relationship between RRD and laser refractive surgery. METHODS: We examined age distribution, refractive error, time interval of RRD onset after refractive surgery, shape and location of retinal break, extent of RD, refractive change and postoperative complications in fifteen patients who experienced RRD after LASIK(9 eyes), or PRK(6 eyes) from March 1993 to August 2001. RESULTS: 66% of patents were in twenties, 47% of patients developed RD within 1 year after refractive surgery, 80% of patients had horse shoe type retinal tear and refractive changes after RD surgery were within 2 diopters. Patients who had undergone LASIK had shorter time interval in developing RRD, more refractive change, and more complications than those with PRK. CONCLUSIONS: These results suggest that laser refractive surgery can be one of the cause of RD. LASIK had more association with RD than PRK. Thorough retinal exam will be needed in patients undergoing LASIK.

Congenital anomalies occur in 2-3% of neonates and have unknown and variable causes. It's occurance rate is higher in twin gestations than in singleton gestations, especially in monozygotic twins. In most cases of twin anomalies, one fetus is normal and the other fetus is not. When an anomaly is found in one fetus, various tests, such as chorionic villus sampling, amniocentesis, and umbilical cord aspiration are strongly recommended in high risk groups of chromosmal anomaly for accurate diagnosis and proper treatments. A case of congenital anomalies in both twins diagnosed in a 35 year old multiparous woman is presented with brief review of literatures.

BACKGROUND: During 2009 pandemic period, many Koreans were infected and admitted with Influenza A/H1N1. The primary aim of this study was to evaluate whether the structures of an intensive care unit (ICU) were associated with the outcomes of critically ill patients. METHODS: This retrospective observational study examined critically ill adult patients with influenza A/H1N1, who were admitted to 24 hospitals in Korea, from September 2009 to February 2010. We collected data of ICU structure, patients and 90 days mortality. Univariate and multivariate logistic regression analysis, with backward elimination, were performed to determine the most significant risk factors. RESULTS: Of the 239 patients, mortality of 90 days was 43%. Acute physiology and chronic health evaluation (APACHE) II score (p < 0.001), sequential organ failure assessment (SOFA) score (p < 0.0001), nurse to beds ratio (p = 0.039) and presence of intensivist (p = 0.024) were significant risk factors of 90 days mortality. Age (p = 0.123), gender (p = 0.304), hospital size (p = 0.260), and ICU type (p = 0.409) were insignificantly associated with mortality. In a multivariate logistic regression analysis, patients with less than 6 SOFA score had significantly lower mortality, compared with those with more than 10 SOFA score (odds ratio 0.156, p < 0.0001). The presence of intensivist had significantly lower mortality, compared with the absence (odds ratio 0.496, p = 0.026). CONCLUSIONS: In critically ill patients with influenza A/H1N1, the severity of the illness and presence of intensivist might be associated with 90 days mortality.

BACKGROUND: Percutaneous dilatational tracheostomy (PDT) performed by an intensivist in critically ill patients is currently popular. Many studies support the safety and feasibility of PDT. However, there is limited data on the safety and feasibility of PDT performed by intensive care trainees. METHODS: To evaluate the safety and feasibility of PDT performed by intensive care trainees and to compare these with those performed by intensivists, we retrospectively analyzed the clinical characteristics and adverse events of all prospectively registered patients who underwent PDT by ICT or intensivists in intensive care units (ICUs) from August 2010 to August 2013. RESULTS: In the study period, 203 patients underwent PDT in ICUs; 139 (68%) by trainees and 64 (32%) by intensivists. There were no statistically significant differences in clinical characteristics including demographics, laboratory findings, and parameters of mechanical ventilation between the two groups. Procedure times and outcomes of the patients were not different between the two groups. The majority of complications observed in 24 hours after PDT were bleeding; however, there was no significant difference between the two groups (trainee 10.8% vs. intensivist 9.4%, p = 0.758). There was no procedure-related death in the two groups. CONCLUSIONS: PDT performed by intensive care trainees was safe and feasible. However, further well-designed studies should be conducted to confirm our results.

Small-bore flexible feeding tubes decrease the risk of ulceration of the nose, pharynx, and stomach compared with large-bore and more rigid tubes. However, small-bore feeding tubes have more respiratory system complications, such as pneumothorax, hydropneumothorax, bronchopleural fistula, and pneumonia, which are associated with significant morbidity and mortality. Thus, it is important to confirm the correct position of feeding tubes. Chest X-ray is the gold standard to detect tracheal malpositioning of the feeding tube. We present three cases in which intubated patients exhibited an altered mental state. An assistant guide wire was used at the insertion of small-bore feeding tubes. These conditions are thought to be potential risk factors for tracheobronchial malpositioning of feeding tubes.

The purpose of this study was to investigate the clinical aspects of patients satisfying the Infectious Disease Society of America/American Thoracic Society (IDSA/ATS) minor severity criteria, focusing on their treatment response to empirical antibiotics. In total, 381 community-acquired pneumonia (CAP) patients who did not require mechanical ventilation or vasopressors at admission were enrolled, and 50 (13.1%) satisfied the minor severity criteria (i.e. , minor severe CAP [minor-SCAP]). The rates of new complication events and clinical treatment failure were significantly higher in the minor-SCAP group than in the control group (30.0% vs 2.1%, P < 0.001, and 42.0% vs 10.6%, P < 0.001, respectively), and the time to reach clinical stability was longer in the minor-SCAP group (8 days vs 3 days, P < 0.001). In a multivariate model, minor severity criteria (> or = 3) were significantly associated with treatment failure (odds ratio, 2.838; 95% confidence interval, 1.216 to 6.626), and for predicting treatment failure the value of the area under the receiver operating characteristic curve for minor criteria was 0.731, similar to other established scoring methods. The IDSA/ATS minor severity criteria can predict delayed treatment response and clinical treatment failure.
