Castleman disease rarely presents as an isolated retroperitoneal mass. We report two cases of retroperitoneal Castleman disease. Sonography showed hypoechoic mass. in two CT demonstrated homogeneously enhancing mass in two cases and calcifications in one case.

We present a rare case of movable mass which attached to chordae and papillary muscle of anterior leaflet of mitral valve in left ventricle discovered preoperative echocardiography. The mass had risks of mechanical obstruction and hemodynamic instability. The patient underwent excision of mass and mitral valve replacement. The diagnosis of papillary fibroelastoma was confirmed by histologic examination. The surgery was done without any complications by safe and cautious anesthetic management without any complications.

Background/Aims: Integrated relaxation pressure (IRP) is a critical diagnostic criterion to define achalasia. However, there are some cases with typical symptoms and signs of achalasia but with normal IRP. The aim of this study is to evaluate the clinical characteristics of patients with achalasia with normal IRP and outcomes after peroral endoscopic myotomy (POEM). Methods: Patients with achalasia were collected in whom POEM was performed from November 2014 to April 2018 at CHA Bundang Medical Center. Achalasia with normal IRP was defined by findings compatible to achalasia in Eckardt score, endoscopy with endoscopic ultrasound, high-resolution manometry, impedance planimetry (EndoFlip), and timed esophagogram. Results: POEM was performed in 89 patients with achalasia; among them, 24 (27%) patients were diagnosed with achalasia with normal IRP. Patients with achalasia with normal IRP were older, had longer duration of symptom, and had a more tortuous esophagus. In EndoFlip, the distensibility index and cross-sectional area were higher in patients with normal IRP. Therapeutic outcomes showed no statistically significant differences. On correlation analysis, IRP had negative correlations with age, disease duration, and distensibility index. Conclusions Patients with achalasia of normal IRP value were older and had longer disease duration and higher distensibility index and crosssectional area than patients with achalasia with abnormal relaxation of lower esophageal sphincter. Therapeutic outcomes were not different between the 2 groups.

BACKGROUND: Ischemia reperfusion (IR) injury is a complex phenomenon that leads to organ dysfunction and causes primary liver failure following liver transplantation. We investigated whether an intravenous administration of magnesium before reperfusion can prevent or reduce IR injury. METHODS: Fifty-nine living donor liver transplant recipients were randomly assigned to an MG group (n = 31) or an NS group (n = 28). Each group was also divided in two groups based on the preoperative magnesium levels (normal: > or = 0.70 mmol/L, low: < 0.70 mmol/L). The MG groups received 25 mg/kg of MgSO4 mixed in 100 ml normal saline intravenously before reperfusion and the NS groups received an equal volume of normal saline. The levels of lactate, pH, arterial oxygen tension, and base excess were measured to assess reperfusion injury at five specific times, which were 10 min after the beginning of anhepatic phase, and 10, 30, 60 and 120 min after reperfusion. To evaluate postoperative organ function, the serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin and creatinine levels were measured at preoperative day 1, postoperative day 1 and 5. RESULTS: The blood lactate levels were significantly lower at 10, 30, 60 and 120 min after reperfusion in the MG groups compared to the NS groups. In addition, significantly higher blood lactate levels were observed in the NS group with preoperative hypomagnesemia than in MG groups. CONCLUSIONS: Magnesium administration before reperfusion of liver transplantation significantly reduces blood lactate levels. These findings suggest that magnesium treatment may have protective effects on IR injury during living donor liver transplantation.

BACKGROUND: Spinal anesthesia for urologic surgery in elderly patients is preferred. The addition of opioids to local anesthetics reduces the side effects of spinal anesthesia. This study examined the effects of intrathecal fentanyl 10microgram and 20microgram when administered with hyperbaric 0.5% bupivacaine to elderly patients undergoing urologic surgery. METHODS: Forty-five elderly patients undergoing urologic surgery were randomized into the following three groups: group 1, bupivacaine 7.5 mg; group 2, bupivacaine 5 mg + fentanyl 10microgram; and group 3, bupivacanie 5 mg + fentanyl 20microgram. The total volume of intrathecally injected was adjusted to 1.5 ml with sterile normal saline. Spinal anesthesia was administered with a 25 G Quincke needle at the L3-4 or L4-5 interspace in the lateral position. The neural block was assessed using a pinprick test and the Bromage scale. RESULTS: There were no significant differences in the onset time of the T10 sensory block, peak level of the sensory block, and onset time of the peak level. The duration of the sensory block was significantly shorter in group 2 than in group 1 (P = 0.017). The duration of the motor block was longer in group 1 than in groups 2 and 3 (P = 0.016, P = 0.04). Pruritus was observed more often in group 3 (37.5%) and shivering was more common in group 1 (P = 0.005). CONCLUSIONS: The addition of fentanyl 10microgram and 20microgram to bupivacaine 5 mg provides adequate anesthesia for elderly patients undergoing urologic surgery with fewer side effects, and fentanyl 10microgram is recommended as outpatient anesthesia.

BOOP(Bronchiolitis Obliterans Organizing Pneumonia) is an inflammatory reaction that follows damage to the bronchiolar epithelium of the small conducting airways. BOOP is characterized by the pathologic finding of excessive proliferation of granulation tissue within the respiratory bronchioles, alveolar duct and spaces, accompanied by organizing pneumonia. BOOP may result from diverse causes such as toxic fumes, connective tissue disorders, infections, organ transplantation and drugs or appear idiopathically. Drug induced BOOP has been described in association with acebutolol, amiodarone, cephalosporin, bleomycine, tryptophan, gold salts, barbiturates, sulfasalazine, and carbamazepine. Carbamazepine is an iminostilbene derivative that is used as both and anticonvulasnt and pain reliever for pains associated with trigeminal neuralgia. It is structually related to the tricyclic antidepressants. To our knowledge, there have been no previously reported case that has described development of BOOP during carbamazepine treatment in Korea, and only two cases have been reported in the world. We report a case of carbamazepine-induce BOOP with a brief review of literature.
