BACKGROUND: Kidney transplantation is an effective renal replacement therapy for patients with end-stage renal disease (ESRD). In this study, we assessed the impact of the baseline characteristics and comorbidities of ESRD patients on the probability of deceased donor kidney transplantation (DDKT) and evaluated the morbidity and mortality during the time spent waiting. METHODS: The study population consisted of 544 ESRD patients on the waiting list for DDKT at Chungnam National University Hospital in South Korea between February 2000 and October 2015. The patients were observed from the date of transplantation list registration to the date of transplantation. Baseline characteristics and comorbidities were investigated together with new-onset comorbidities that occurred during the waiting time. RESULTS: Diabetes mellitus (39.0%), hypertension (25.2%), and glomerulonephritis (21.3%) were the three most common causes of ESRD in this study, and coronary artery disease (9.4%) was the most common comorbidity. The 115 patients (19.3%) who underwent DDKT had a mean waiting time of 1,711 days (768–2,654 days or 4.68 years [2.10–7.27]). Blood groups other than type O, peritoneal dialysis, and nondiabetic ESRD were significantly associated with a higher likelihood of DDKT. Infection was the leading cause of death and the most common comorbidity that arose during the waiting time. Patients who experienced cardiovascular events during the waiting time showed a lower transplant rate compared with those who did not. CONCLUSION: The prevalence of comorbidities was high in renal transplantation candidates. During the often-long waiting time, new comorbidities may occur, with long-term sequelae limiting access to kidney transplantation or resulting in death.

BACKGROUND: Laryngopharyngeal reflux (LPR) disease has many symptoms such as globus pharyngeus, excessive throat clearing and hoarseness. The aim of this study was to investigate the effect of stellate ganglion block (SGB) in addition to proton pump inhibitors (PPI) on LPR. METHODS: Fifty patients complaining of more than 3 typical LPR symptoms for over 3 months were enrolled in the study. The P group took PPI for 8 weeks. The SP group took PPI and interwent a series of 8 SGB procedure once a week during the period of treatment. The blocks were performed one at a time unilaterally on the right and left stellate ganglions by injecting 1% mepivacaine 6 ml. We evaluated the reflux symptom index (RSI) before treatment and following 4 weeks and 8 weeks of treatment in both groups. RESULTS: After 4 weeks of treatment, the RSI of the P group decreased, but not significantly, to 16.6 +/- 6.8 compared with the baseline value of 19.2 +/- 2.7 (P = 0.093), whereas the RSI of the SP group decreased significantly to 9.8 +/- 3.3 compared with the baseline value of 19.0 +/- 4.7 (P = 0.000). After 8 weeks of treatment, the RSI of the P group decreased significantly to 13.7 +/- 6.7 (P = 0.001) and the RSI of the SP group also decreased significantly to 7.7 +/- 3.4 (P = 0.000). There were significant differences in the RSI between the two groups after 4 weeks (P = 0.000) and 8 weeks (P = 0.001) of treatment. CONCLUSIONS: The symptoms of LPR improved earlier when PPI therapy was combined with SGB compared with PPI therapy alone.

BACKGROUND: Many pieces of previous research on measuring blood pressure (BP) using different methods focused on the disparity in the results. However, none of them dealt with the disparity caused by the difference in age and inhalation anesthetics. We attempted to find the variance in accordance with age, body part, and measuring methods (invasive vs noninvasive) and also studied how sevoflurane influences BP as the operation progresses. METHODS: In sixty patients, we measured the arterial BP in the upper and lower limbs by noninvasive methods before inducing anesthesia. After induction, we used sevoflurane to maintain anesthesia, and injected catheters into the radial artery and dorsalis pedis artery to measure arterial pressure at every ten minute by both invasive and noninvasive methods. RESULTS: The patients who were 40 or older showed significantly higher values in the systolic BP than the patients younger than 40. The values of systolic and diastolic BP measured by a noninvasive oscillometric method were meaningfully higher than those measured by an invasive method. As the operations progressed, the lower limbs showed higher systolic pressure than the upper limbs regardless of measuring methods, whereas the opposite is true for diastolic pressure. CONCLUSIONS: The values in the arterial BP were measured high by noninvasive method. Systolic BP were estimated significantly high in the older patients and in the lower leg. Due to the effect of sevoflurane, the diastolic BP in the lower limbs becomes lower than that of upper limbs regardless of measuring methods, as the operation progresses.

Surgical procedures necessitating the prolonged use of the lithotomy position can be associated with neuromuscular dysfunction. Compartment syndrome of the lower leg is a grave complication which, if unrecognized, can lead to either permanent neuromuscular dysfunction or limb loss. We report a case of compartment syndrome of lower leg that occurred in male patient aged 20 years after 380 minutes arthroscopic surgery in the lithotomy position.

PURPOSE: To evaluate the incidence and clinical features of age-related macular degeneration (AMD) in Korea. METHODS: Web-based (www.armd-nova.or.kr) registration was conducted for AMD patients aged 50 or more who were newly diagnosed by retinal specialists in Korea from August 20, 2005 to August 20, 2006. Patient data including ophthalmologic examination, fundus photography, fluorescein angiogram and/or indocyanin green angiogram (ICG), past medical history, behavioral habit, combined systemic diseases were up-loaded. RESULTS: Among finally enrolled 1,141 newly diagnosed AMD patients, 690 patients (60.5%) were male and 451 patients (39.5%) were female. The average age of AMD patients was 69.7+/-8.0. Early AMD was observed in 190 patients and 951 patients had late AMD. Classic choroidal neovascular membrane (CNVM) was observed in 18.6% of exudative AMD patients and 63.4 % had occult CNVM. Subfoveal CNVM was observed in 80.4% of the patients with CNVM. Among the 580 exudative AMD eyes that performed indocyanin green angiography (ICG), 184 eyes (31.7%) had polypoidal choroidal vasculopathy (PCV) and 36 eyes (6.2%) showed retinal angiomatous proliferation (RAP). Age, male gender, smoking, diabetes and hypertension significantly increased the risk of the AMD among Koreans. CONCLUSIONS: Because of the low rate of participation by retinal specialists, definite incidence of AMD was not obtainable. However, the estimated 1-year AMD incidence in the Pusan area of Korea is at least 0.4%. In contrast to Western people, 31.7% of exudative AMD cases were revealed to be PCV and 6.2% were revealed to be RAP. This discrepancy between ethnic groups should be considered in the diagnosis and treatment modality selection of Korean AMD patients.

H type of congenital tracheoesophageal fistula (TEF) is rare, occurring approximately once in 100,000 births. The presentation of this anomaly in adults is indeed uncommon. We report a case of a 47-year-old male with congenital TEF dectected during epidural hematoma removal under general anesthesia. Intermittent disappearance of normal capnography, bubbling sound at substernal area, and air leakage at oral cavity observed during manually assisted ventilation, especially during inspiration. We observed a H-type of TEF and tracheal intubation via esophagus in chest CT after operation.

BACKGROUND: Breast reconstruction following mastectomy has become increasingly popular in recent years. The purpose of this study was to compare the efficacy of cervical epidural patient-controlled analgesia (CEA) and intravenous patient-controlled analgesia (IV-PCA) for controlling the postoperative pain and the side effects after mastectomy with immediate Latissimus dorsi (LD) flap breast reconstruction. METHODS: Sixty patients who were to undergo mastectomy with immediate LD flap breast reconstruction were randomly assigned to receive CEA [Group CEA, (n = 30), 0.15% ropivacaine + fentanyl 4 microg/ml] or IV-PCA [Group IV-PCA (n = 30) fentanyl 20 microg/kg + ketorolac 3 mg/kg] for postoperative pain control via a PCA pump (basal rate: 2 ml/h, bolus: 2 ml, lock out interval: 15 min) after their operation. Before general anesthesia, an epidural catheter was inserted at the cervical (C)7-thoracic (T)1 level in the patients of the CEA group. The resting visual analogue scale (VAS) for pain, the systolic blood pressure, the heart rate and the side effects were recorded for 48 hours after operation. RESULTS: The VAS at rest was significantly lower in the CEA group than that in the IV-PCA group at 16 hours after surgery. The CEA group required less additional analgesics as compared with the group IV- PCA. There were no significant differences in the systolic blood pressure, the heart rate and the incidence of side effects between the two groups. CONCLUSIONS: We conclude that cervical epidural analgesia, as compared with intravenous patient-controlled analgesia, provides effective pain control and it shows a similar incidence of side effects after mastectomy with immediate LD flap breast reconstruction.

BACKGROUND: Information concerning the cardiopulmonary effects of pneumoperitoneum in children is lacking. METHODS: Twenty eight patients were assigned to receive diagnostic laparoscopy (n = 12) or laparoscopic surgery (n = 16). Before insufflation of CO2, tidal volume was set at 10 ml/kg and respiratory rate was adjusted to achieve an end-tidal CO2 (P(ET)CO2) of 30-35 mmHg. Abdominal pressure was maintained at 10-15 mmHg by a CO2 insufflator. We measured the changes of systolic arterial pressure (SAP), heart rate (HR), P(ET)CO2 and peak airway pressure (PAP) at 5 min before (control value) and after CO2 insufflation and 5 min after CO2 deflation. RESULTS: SAP and PAP were increased significantly after pnemoperitoneum compared with the control both in diagnostic laparoscopy and laparoscopic surgery (P < 0.05). P(ET)CO2 was increased significantly after pneumoperitoneum and after CO2 deflation in laparoscopic surgery compared with the control and also with diagnostic laparoscopy (P < 0.05). Driving pressure (the difference between peak airway pressure and abdominal pressure) was increased significantly after pneumoperitoneum in laparoscopic surgery compared with diagnostic laparoscopy (P < 0.05). CONCLUSIONS: SAP, PAP and P(ET)CO2 increases during diagnostic laparoscopy and laparoscopic surgery, but this effect appears to be of smaller magnitude in diagnostic laparoscopy compared to laparoscopic surgery. We found that these changes had no clinically deleterious effects in healthy children.

Corticosteroid preparations have anti-inflammatory and immunosuppressive properties and are used widely for the treatment of allergic disorders and asthma. Steroids themselves, however, can induce hypersensitivity reactions. In this study, we report the case of a 66-year-old man with chronic obstructive pulmonary disease who exhibited an allergic reaction (rash, bronchospasm, bradycardia, severe hypotension and cardiac arrest) immediately after the intravenous injection of methylprednisolone sodium succinate. Despite cardiopulmonary resuscitation, sinus rhythm was not restored. The anesthesiologist should be aware that allergic reactions to corticosteroids can occur.

BACKGROUND: The popularity and the demand for Nuss procedure have increased dramatically. Many pediatric surgeons became familiarized with Nuss procedure and have applied it to a large number of patients. But the intraoperative and the postoperative complications have not been defined yet. METHODS: 630 patients, who underwent the Nuss procedure between August 1999 and December 2006, were studied retrospectively. Risk factors and complications were obtained from chart review and anesthesia records, and analyzed statistically. RESULTS: Complication rates were 127/630 (20.1%) in total patients. Frequent complications were arrhythmia 37 (5.8%), pneumothorax 29 (4.6%), pleural effusion 15 (2.4%), wound infection 14 (2.2%), bar displacement 13 (2%) and pericarditis 9 (1.3%) in order. Resk factors are severity of pectus excavatum and lack of surgeon's experience (P < 0.05). CONCLUSIONS: Nuss procedure has evolved into an effective method of pectus excavatum repair. To reduce the complications, there must be precise preoperative assessment of computed tomography index (CTI) and intensive postoperative management in the operative day.
