ABSTRACT
Optic neuritis is a rare extraintestinal manifestation of inflammatory bowel disease. Antitumor necrosis factor alpha (anti-TNF-α) agents are essential treatment options in inflammatory bowel diseases. However, anti-TNF-α agents can implicate optic neuritis and other demyelinating diseases as complications of these agents. We report a patient of infliximab-induced optic neuritis in a patient with ulcerative colitis who was treated with high-dose steroids after discontinuation of infliximab.
ABSTRACT
Duodenal neuroendocrine tumors (NETs) are subepithelial tumors that are difficult to remove endoscopically, particularly when located just beyond the pylorus. This paper reports a case of a successful endoscopic submucosal dissection (ESD) using open gastric peroral endoscopic myotomy (POEM) for a remnant duodenal NET detected after endoscopic mucosal resection (EMR). A 67-year-old male presented with a 5 mm remnant duodenal NET close to the pylorus after EMR for a duodenal polypoid lesion performed four months earlier. Duodenal ESD was performed under conscious sedation using I-type and IT II knives. The tumor adhered to the fibrotic tissue, and the submucosal cushion was insufficient. Open gastric POEM was performed concurrently during ESD, resulting in the complete resection of the NET. This case suggests that while challenging, open gastric POEM can serve as a valuable technique for endoscopic resection in cases of early gastric cancer or duodenal masses located around the pylorus.
ABSTRACT
BACKGROUND@#This prospective study aimed to determine whether the bispectral index (BIS) is a valid objective tool for differentiating adequate from inadequate deep sedation in spontaneously breathing children with cerebral palsy (CP).@*METHODS@#Propofol was titrated to increase the level of sedation with a continuous infusion of remifentanil at a rate of 0.05 μg/kg/min while maintaining spontaneous ventilation in 22 children with spastic CP, aged 3–18 years. The depth of sedation was assessed using the University of Michigan Sedation Scale (UMSS) and the Modified Observer’s Assessment of Alertness and Sedation (MOAAS) scale. Receiver operating characteristic curve analysis was performed to determine the cutoff BIS values for deep sedation, defined as a UMSS score of 3–4 and a MOAAS score of 0–1.@*RESULTS@#The BIS values significantly changed with the increase in the level of sedation across both the UMSS and MOAAS scores (P < 0.001). The BIS values correlated with the UMSS (r = −0.795, P < 0.001) and MOAAS (r = 0.815, P < 0.001) scores. The cutoff BIS value to detect adequate deep sedation in children with CP was 61.5 (UMSS score: sensitivity 0.860, specificity 0.814; MOAAS score: sensitivity 0.794, specificity 0.811).@*CONCLUSIONS@#The BIS value strongly correlates with the clinical sedation scales, such as the UMSS and MOAAS, during deep sedation in children with CP. Therefore, BIS monitoring can be used as a valid tool for assessing the level of propofol sedation in spontaneously breathing children with CP undergoing a botulinum toxin injection.

Vascularized composite allotransplantation for the forearm is a complex surgical procedure, requiring multidisciplinary collaboration. It is important to provide optimal blood flow to the grafts, effective immunosuppression, and early rehabilitation for graft survival and good functional outcomes. As ischemia-reperfusion injury and substantial but unquantifiable blood loss are inevitable in this type of surgery, anesthetic management should focus on providing adequate hemodynamic management with proper monitoring, and anesthetic and analgesic strategies to prevent vasoconstriction in the graft. In this paper, we describe the anesthetic management of the first forearm transplantation performed in Korea.
ABSTRACT
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare clonal hematopoietic stem cell disorder. Surgery, anesthesia, infection, trauma, and pregnancy can exacerbate hemolysis and thrombotic risk by increasing complement activity. However, perioperative treatment of eculizumab can reduce risk of hemolytic event by surgical stress. Here, we present the perioperative clinical course and adequate anesthetic management of PNH complicated by spine surgery under general anesthesia. We also describe a possible role of eculizumab for PNH patients with anticipated high risks.

BACKGROUND: The type and regimen of anesthesia may affect perioperative hyperglycemia following major surgical stress. This study compared the effects of sevoflurane and propofol on the incidence of hyperglycemia and clinical outcomes in diabetic patients undergoing lung surgery.METHODS: This retrospective study included 176 patients with type 2 diabetes mellitus who had undergone lung surgery. Blood glucose levels and clinical outcomes from the preoperative period to the first 2 postoperative days (PODs) were retrospectively examined in patients who received sevoflurane (group S, n= 87) and propofol (group P, n=89) for maintenance of general anesthesia. The primary endpoint was the incidence of persistent hyperglycemia (2 consecutive blood glucose levels > 180 mg/dL [10.0 mmol/L]) during the perioperative period. The secondary composite endpoint was the incidence of major postoperative complications and 30-day mortality rate after surgery.RESULTS: Blood glucose levels similarly increased from the preoperative period to the second POD in both groups (p=0.857). Although blood glucose levels at 2 hours after surgery were significantly lower in group P than in group S (p=0.022; 95% confidence interval for mean difference, −27.154 to −2.090), there was no difference in the incidence of persistent hyperglycemia during the perioperative period (group S, 70%; group P, 69%; p=0.816). The composite of major postoperative complications and all-cause in-hospital and 30-day mortality rates were also comparable between the two groups.CONCLUSION: Sevoflurane and propofol were associated with a comparable incidence of perioperative hyperglycemia and clinical outcomes in diabetic patients undergoing lung surgery.

Management of airway in a child with Cornelia de Lange Syndrome (CdLS) should be given due consideration because most of them have the problems related to difficult airway. The GlideScope video laryngoscope can be attempted during routine intubation, however it is mostly used in case of difficulty. With adequate preoperative airway assessment, we used the pediatric video laryngoscope as useful alternative airway device in a child with CdLS and orotracheal intubation proceeded uneventfully.

BACKGROUND: Industrial pollution may affect the heavy metal body burden of people living near industrial complexes. We determined the average concentrations of atmospheric heavy metals in areas close to and distant from industrial complexes in Korea, and the body concentrations of these heavy metals in residents living near and distant from these facilities. METHODS: The atmospheric data of heavy metals (lead and cadmium) were from the Regional Air Monitoring Network in Ulsan. We recruited 1,148 participants, 872 who lived near an industrial complex (“exposed” group) and 276 who lived distant from industrial complexes (“non-exposed” group), and measured their concentrations of blood lead, urinary cadmium, and urinary total mercury. RESULTS: The results showed that atmospheric and human concentrations of heavy metals were higher in areas near industrial complexes. In addition, residents living near industrial complexes had higher individual and combined concentrations (cadmium + lead + mercury) of heavy metals. CONCLUSION: We conclude that residents living near industrial complexes are exposed to high concentrations of heavy metals, and should be carefully monitored.

Adequate maintenance of body temperature during general anesthesia is necessary for safety. Generally, esophageal temperature probe is commonly used in practice for measuring core temperature because of its reliability and feasibility. Proper placement of esophageal temperature probe is important to avoid complications. In this case report, we describe our experience with a patient undergoing lobectomy of the lung in whom the esophageal temperature probe that was misplaced into the right intermediate bronchus was accidentally cut. This case highlights the need to carefully assess correct position of the temperature probe, especially in patients undergoing one-lung ventilation.

BACKGROUND: Epidural analgesia (EPA) has been used for postoperative pain control in total knee replacement (TKR). However, many patients have suffered various side effects after epidural blockade. Peripheral nerve block (PNB) has been shown to provide effective pain relief after TKR. We compared the benefits of continuous femoral nerve block (FNB) combined with single-injection sciatic nerve block (SNB) with those of EPA for postoperative pain management after TKR. METHODS: Eighty participants undergoing unilateral TKR were randomized to receive either EPA (EPA group) or continuous FNB combined with SNB (PNB group). All patients received general anesthesia for TKR. Ropivacaine 2 mg/ml plus fentanyl 2 µg/ml was administered for EPA. Ropivacaine 2 mg/ml was administered through the femoral nerve catheter. The pain score, side effects (dizziness, sedation, nausea, vomiting, pruritus, hypotension and urinary retention), motor blockade, knee range of motion, and rehabilitation were measured postoperatively. The primary outcome measure was the number of patients experiencing side effects. RESULTS: The incidence of patients with side effects was 86.8% in the EPA group but only 35.1% in the PNB group (P < 0.001). There were no significant differences between the two groups in terms of pain score, motor blockade of the operative limb, knee range of motion, or rehabilitation. CONCLUSIONS: Continuous FNB combined with SNB can be an effective alternative to EPA for postoperative pain management in TKR.

BACKGROUND: A motor blockade of lower limbs interferes with early ambulation and limits the usefulness of patient-controlled epidural analgesia (PCEA). The concentration of local anesthetic solution is a major determinant for motor block with PCEA. We compared the effects of epidural infusion of 0.075% ropivacaine with 0.15% epidural ropivacaine on postoperative analgesia, motor block of lower limbs, and other side effects. METHODS: A total of 70 patients undergoing laparoscopic gynecologic surgery received epidural infusions (group R1, 0.15% ropivacaine with fentanyl; group R2, 0.075% ropivacaine with fentanyl). Pain score, motor block, and side effects (hypotension, nausea, vomiting, pruritus, urinary retention, dizziness, and numbness) were measured. RESULTS: There were no significant differences in the demographic profiles between the groups. Pain scores of the group R1 and the group R2 were not significantly different. Motor block was more frequent in the group R1 (0.15% ropivacaine with fentanyl) than in the group R2 (0.075% ropivacaine with fentanyl). CONCLUSION: Lower concentration of ropivacaine (0.075%), when compared with higher concentration of ropivacaine (0.15%), seemed to provide similar analgesia with less motor blockade of the lower limbs for the purpose of PCEA.

BACKGROUND: Recently, noise coming from the neighborhood via floor wall has become a great social problem. The noise between the floors can be a cause of physical and psychological problems, and the different types of floor impact sound (FIS) may have the different effects on the human's body and mind. The purpose of this study is to assess the responses of subjective feeling, task performance ability, cortisol and HRV for the various types of floor impact. METHODS: Ten men and 5 women were enrolled in our study, and the English listening test was performed under the twelve different types of FIS, which were made by the combinations of bang machine (B), tapping machine (T), impact ball (I) and sound-proof mattress (M). The 15 subjects were exposed to each FIS for about 3 min, and the subjective annoyance, performance ability (English listening test), cortisol level of urine/saliva and heart rate variability (HRV) were examined. The sound pressure level (SPL) and frequency of FIS were analyzed. Repeated-measures ANOVA, paired t-test, Wilcoxon signed rank test were performed for data analysis. RESULTS: The SPL of tapping machine (T) was reduced with the soundproof mattress (M) by 3.9–7.3 dBA. Impact ball (I) was higher than other FIS in low frequency (31.5–125 Hz) by 10 dBA, and tapping machine (T) was higher than other FIS in high frequency (2–4 k Hz) by 10 dBA. The subjective annoyance is highest in the combination of bang machine and tapping machine (BT), and next in the tapping machine (T). The English listening score was also lowest in the BT, and next in T. The difference of salivary cortisol levels between various types of FIS was significant (p = 0.003). The change of HRV parameters by the change of FIS types was significant in some parameters, which were total power (TP) (p = 0.004), low frequency (LF) (p = 0.002) and high frequency (HF) (p = 0.011). CONCLUSIONS: These results suggest that the human's subjective and objective responses were different according to FIS types and those combinations.

BACKGROUND: The need of efficient resource management and full-time accessibility to resources has increased with the development of industry, resulting in the increase of shift workers. Previous researches of past decades show that there are various health effects on shift workers. However, the definition and the form of shift work have varied from each research and occupational harmful factors except for shift work have not been excluded completely in previous researches. Therefore, in this research, we tried to find out the effect of shift work focusing on the hypertension. To complement previously mentioned weakness of other researches, we performed our research on participants to whom we could minimize other risk factors excluding shift work. METHODS: This research examined 1,953 petrochemical plant male workers (shift work 1,075, day worker 878) who did medical checkup from 1st Jan. 2014 to 31th Dec. 2014 in a general hospital located in Ulsan, based on their medical records and questionnaires. With the questionnaire, we found out their basic information including age, social status, occupational history, and we took their physical measurements. RESULTS: Compared to day workers, shift workers' odds ratio of developing hypertension was 1.31 (95% CI 0.98–1.75). After adjusting confounding variables, adjusted odds ratio for entire subjects was 1.51 (95% CI 1.11–2.06). Also, for subjects who were in continuous service for over 20 years, odds ratio was 1.51 (95% CI 1.08–2.11). CONCLUSIONS: Shift workers had a higher chance of hypertension than day workers do. Particularly, the longer the workers work continuously, the risk of hypertension getting higher.

Concurrent injury of medial malleolus and deltoid ligament is difficult to occur considering the injury mechanism. When the concurrent injury comes about, the deltoid ligament injury could be missed and it may lead to medial ankle instability. There are few reported cases of the concurrent injury and domestic case of concurrent failure of both structures over the medial side has been reported just once; however, the injury mechanism is different from this case. The authors report a case of medial malleolus fracture with deltoid ligament rupture following pronation injury with a review of necessity of repairing deltoid ligament for ankle stability.
