1.  Prolonged Survival of a Refractory Acute Myeloid Leukemia Patient after a Third Hematopoietic Stem Cell Transplantation with Umbilical Cord Blood following a Second Relapse 
Case Reports in Hematology  2014;2014:918708.
Although hematopoietic stem cell transplantation (HSCT) has been considered to be the only way for potential cure of relapsed acute myeloid leukemia (AML), there has been no report on a third HSCT in patients with multiple relapsed AML. Here, we report a case of 53-year-old female who received a successful third allogeneic HSCT after relapse of AML following a second allogeneic HSCT. She was treated with a toxicity reduced conditioning regimen and received direct intrabone cord blood transplantation (CBT) using a single unit of 5/6 HLA-matched cord blood as a graft source. Graft-versus-host disease prophylaxis was performed with a single agent of tacrolimus to increase graft-versus-leukemia effect. She is in remission for 8 months since the direct intrabone CBT. This report highlights not only the importance of individually adjusted approach but also the need for further investigation on the role of HSCT as a treatment modality in patients with refractory or multiple relapsed AML.

2.  The role of chemotherapy and/or octreotide in patients with metastatic gastroenteropancreatic and hepatobiliary neuroendocrine carcinoma 
Background
Neuroendocrine carcinomas (NECs) of the gastro-entero-pancreatic (GEP) and hepatobiliary (HB) tract are rare and a heterogenous group of malignancies. Octreotide showed the anti-tumor activity in functional and nonfunctional well differentiated metastatic midgut neuroendocrine tumors (NETs). However, the effect of octreotide on survival has not been evaluated.
Patients and methods
We analyzed 17 patients (6 HB- and 11 GEP- tract) with metastatic NEC diagnosed between January 2009 and June 2012. All patients had one or more cytotoxic chemotherapy and nine patients had received octreotide as single agent (n=3) or combination of cytotoxic chemotherapy (n=6).
Results
The median age was 68 years (range, 23-79 years) and median Eastern Cooperative Oncology Group performance status (ECOG PS) was 1. Sixteen of all patients (n=17) received cytotoxic chemotherapy with or without octreotide as the first line therapy and 10 of 16 patients who experienced disease progression to the first line therapy received the second line therapy. Overall response rates (RR) and disease control rates (DCR) to the 1st line therapy were 41.2% and 76.5%, respectively. The median overall survival (OS) was 16 months [95% confidence interval (CI), 12.8-19.2] and the median OS in patients receiving octreotide during treatment was 40.2 months. In univariate analysis, any clinico-pathologic features including sex, the location of primary tumor, the number of metastatic sites, the debulking operation and the liver metastasis did not have prognostic value regarding OS. However, the use of octreotide offered favorable trend for OS (P=0.091).
Conclusions
The use of octreotide may benefit for patients with GEP- and HB- NECs as a single agent or a combination therapy.

3.  Case Report of Pulmonary Sarcoidosis Suspected to be Pulmonary Metastasis in a Patient with Breast Cancer 
Standard endocrine therapy and chemotherapy can induce long-term remission in breast cancer patients; however, breast cancer can recur at any site. Pulmonary nodules with lymphadenopathy in advanced cancer patients are likely to be assumed as metastases. A 44-year-old woman with a history of breast cancer was presented to our institution with abnormal findings on 18-fluorodeoxyglucose positron emission tomography imaging, which suggested lung metastasis. She had previously been diagnosed with breast cancer (T1N2M0, Stage IIIa, intraductal carcinoma, triple negative cancer). Histological analysis of the mediastinal lymph node biopsy demonstrated sarcoidosis, showing a chronic, non-caseating, granulomatous inflammation. Our case highlights the need for non-malignant diagnoses in those with prior malignancies, and the need for histological evaluations in the event of first recurrence following potentially curative therapy.

5.  Successful treatment of disseminated interdigitating dendritic cell sarcoma with adriamycin, bleomycin, vinblastine, and dacarbazine chemotherapy 
The Korean Journal of Hematology  2012;47(2):150-153.
Interdigitating dendritic cell sarcoma (IDCS) is a very rare and aggressive neoplasm that arises from antigen presenting cells. IDCS usually involves lymph nodes; however, extra-nodal involvement has also been reported. Because a consistent standard therapy for IDCS has not been established to date, we report a case of the successful treatment of disseminated IDCS using ABVD chemotherapy (doxorubicin, bleomycin, vinblastine, and dacarbazine). A 64-year-old man was diagnosed with IDCS on the basis of immunohistochemical findings of a biopsy specimen of the inferior nasal concha. Immunohistochemical staining showed a positive reaction for CD68, leukocyte common antigen, and S-100 protein, but a negative reaction for CD34, CD1a, and CD21. Imaging studies showed cervical and axillary lymphadenopathies, subcutaneous nodules, and a soft tissue lesion in the nasal cavity. Treatment with the ABVD regimen resulted in complete remission after 8 cycles of chemotherapy.

6.  Urinary bladder rupture during voiding cystourethrography 
Korean Journal of Pediatrics  2012;55(5):181-184.
Voiding cystourethrography (VCUG) is a commonly performed diagnostic procedure for the evaluation of vesicoureteral reflux with urinary tract infection or congenital renal diseases in children. The procedure is relatively simple and cost-effective, and complications are very rare. The iatrogenic complication of VCUG range from discomfort, urinary tract infection to bacteremia, as well as bladder rupture. Bladder rupture is a rare complication of VCUG, and only a few cases were reported. Bladder rupture among healthy children during VCUG is an especially uncommon event. Bladder rupture associated with VCUG is usually more common in chronically unused bladders like chronic renal failure. Presented is a case of bladder rupture that occurred during a VCUG in a healthy 9-month-old infant, due to instilled action of dye by high pressure. This injury completely healed after 7 days of operation, and it was confirmed with a postoperative cystography. The patient's bladder volume, underlying disease, velocity of the contrast media instilled, catheter size, and styles of instillation are important factors to prevent bladder rupture during VCUG. Management of bladder rupture should be individualized, but the majority of infants are treated with the operation. In conclusion, bladder rupture is a rare complication, however, delicate attention is needed in order to prevent more dire situations.

7.  A survey of user acceptance of electronic patient anesthesia records 
Korean Journal of Anesthesiology  2012;62(4):350-357.
Background
An anesthesia information management system (AIMS), although not widely used in Korea, will eventually replace handwritten records. This hospital began using AIMS in April 2010. The purpose of this study was to evaluate users' attitudes concerning AIMS and to compare them with manual documentation in the operating room (OR).
Methods
A structured questionnaire focused on satisfaction with electronic anesthetic records and comparison with handwritten anesthesia records was administered to anesthesiologists, trainees, and nurses during February 2011 and the responses were collected anonymously during March 2011.
Results
A total of 28 anesthesiologists, 27 trainees, and 47 nurses responded to this survey. Most participants involved in this survey were satisfied with AIMS (96.3%, 82.2%, and 89.3% of trainees, anesthesiologists, and nurses, respectively) and preferred AIMS over handwritten anesthesia records in 96.3%, 71.4%, and 97.9% of trainees, anesthesiologists, and nurses, respectively. However, there were also criticisms of AIMS related to user-discomfort during short, simple or emergency surgeries, doubtful legal status, and inconvenient placement of the system.
Conclusions
Overall, most of the anesthetic practitioners in this hospital quickly accepted and prefer AIMS over the handwritten anesthetic records in the OR.

8.  Novel Use of Hydromorphone as a Pretreatment Agent: A Double-blind, Randomized, Controlled Study in Adult Korean Surgical Patients 
Background
Hydromorphone is a potent μ-opioid selective agonist that has an onset time within 5 minutes and reaches peak effect between 10 and 20 minutes. However, it may show immediate analgesic effect to rocuronium-induced pain because of its peripheral analgesic property and also may attenuate noxious stimuli from tracheal intubation during induction. The opioid receptors are known to be present in peripheral sensory nerve terminals as well as in the dorsal root ganglion and the central terminal of primary afferent nerves. Therefore, we hypothesized that hydromorphone may be considered a potent pretreatment or adjuvant drug during the induction of anesthesia with its peripherally and centrally mediated analgesia.
Objective
The aim of this study was to compare the effects of pretreatment with hydromorphone in reducing rocuronium-induced withdrawal movements and hemodynamic changes during tracheal intubation with the effects of fentanyl and normal saline.
Methods
In this double-blind, randomized, controlled study, consecutive adult patients aged 20 to 70 years who were scheduled to undergo general anesthesia for elective gastric or colorectal surgery at the Samsung Seoul Hospital (Seoul, Republic of Korea) were randomly assigned to receive 5 mL hydromorphone 0.03 mg/kg or fentanyl 2 μg/kg or normal saline. Thirty seconds after administering the study drug, anesthesia was induced with 2.5% thiopental sodium 5 mg/kg. After loss of consciousness, rocuronium 0.6 mg/kg was injected and immediate withdrawal movements were recorded. Two minutes after rocuronium injection, tracheal intubation was performed and hemodynamic changes were observed.
Results
A total of 194 patients were enrolled, with 65 in the hydromorphone group, 67 in the fentanyl group, and 62 in the saline group. The overall incidence of withdrawal movements was significantly lower in the hydromorphone group (2 patients; 3.1%) and the fentanyl group (5 patients; 7.5%) (both, P < 0.001) than in the saline group (36 patients; 58.1%). The mean arterial pressure (MAP) and heart rate (HR) after intubation (median [interquartile range]) in the fentanyl group (101.5 [84−115] mm Hg; 93.5 [82−102] beats per minute [bpm]) and the hydromorphone group (93.0 [83−106] mm Hg; 90.0 [86.3−93.6] bpm) were significantly lower than these measures in the saline group (111.5 [105−123] mm Hg; 103.5 [96−113] bpm) (fentanyl group MAP and HR, P < 0.001; hydromorphone group MAP and HR, P < 0.001).
Conclusions
Pretreatment with hydromorphone and fentanyl may have similar effectiveness in reducing withdrawal movements in response to rocuronium injection pain and inducing immediate general anesthesia.
