Jehovah's Witnesses refuse a transfusion of blood or blood products because of religious beliefs; this refusal at times presents a dilemma for the treating physician. We report a case of a 25-year-old Jehovah's Witness patient who underwent a reoperation for a previous proximal humerus shaft fracture and experienced unexpected massive hemorrhage intraoperatively and postoperatively. The postoperative lowest hemoglobin level was 2.9 g/dl. The patient recovered from the severe anemia without any clinical sequala. We review the legal, ethical and religious issues and suggest the best possible medical care that Jehovah's Witness patient would permit.

OBJECTIVES: Endoscopic Ultrasonography (EUS) is widely used to diagnose upper gastrointestinal tract disease. In recent, it is reported that EUS is also goood diagnostic method to assess depth of invasion through rectal wall and lymph node involvement of rectal cancer. We performed EUS in preoperative rectal cancer patients and compared to post operative histologic findings to evaluate EUS diagnostic accuracy for rectal cancer staging system METHODS: 51 patients with rectal cancer were performed with EUS. They were diagnosed by endoscopic biopsy from August 1994 to June 1996 at Kangbuk Samsung Hospital. Their ages were 28 to 78 (mean: 55 years) and the male to female ratio was 2 : 1 (34/17). Olympus GF-UM3, EU-M3 EUS and 7.5/12 MHz transducer were utilized. EUS was performed by the deaerated water filling method. We have analyzed between preoperative EUS findings and postoperative biopsy findings in order to evaluate the accuracy of EUS. The accuracy of EUS was signified by percentage. RESULTS: 1) Endoscopic ultrasonographic accuracy for assessment of wall invasion of rectal cancer was as follows ; The accuracy of mucosal cancer was 50% (patient numbers of EUS diagnosis/patient numbers of histologic diagnosis: 2/4). Submucosal cancer was 100% (1/1). Muscularis propria cancer was 44% (4/9). The accuracy with penetration to subserosa (or perirectal fat tissue) was 97% (33/34). The accuracy with invasion to adjacent organ was 33% (1/3). The overall accuracy rate was 80% (41/51). 2) EUS accuracy of lymph node metastasis in rectal cancer was ; The sensitivity was 90% (patient numbers of EUS diagnosis/patient numbers of histologic diagnosis: 28/31). The specificity was 60% (12/20). 3) EUS diagnosis of modified Duke classification was ; The accuracy of A stage was 80% (patient numbers of EUS diagnosis/patient numbers of histologic dagnosis: 4/5). B1 stage was 60% (4/8). B2 stage was 33% (1/3). C1 stage was 0% (0/3). C2 stage was 86%(25/28). D stage was 33% (1/3). The overall accuracy rate was 69% (35/51). CONCLUSION: EUS is useful method to assess rectal cancer invasion through rectal wall and lymph node involvement. However, further refinements in instruments and the techniques is required for more improving diagnostic accuracy.

Necrotizing fasciitis is a relatively uncommon infectious disorder where a bacterial organism penetrates the subcutaneous tissues and superficial fascia, ultimately causing necrosis of vast areas of soft tissue. Although invasive Streptococcus spp., most commonly group-A streptococci, is the most frequent cause of this disorder, in a single organism-infection, necrotizing fasciits caused by Klebseilla pneumoniae is becoming more frequently reported, perhaps due to the recent increase in the frequency of diabetes and liver diseases. Necrotizing fasciitis caused by K. pneumoniae is usually secondary to hematogenous dissemination, most commonly caused by trauma or liver abscess and usually results in multiple organ failure. The progression of the disease is so rapid that the mortality rate is high despite aggressive surgical intervention and extensive use of antibiotics at an early disease stage. Here we report a case of necrotizing fasciitis caused by hematogenously spread K. pneumoniae from incompletely treated chronic otitis media in a patient with alcoholic liver cirrhosis and diabetes.

Mulitiple intracranial aneurysms occur in range of 15% to 30% of all patients with intracranial aneurysms. The treatment of such patients offers a particular challenge for the neurosurgeon. Early reports dealing with multiple aneurysms recommended treatment of only the ruptured aneurysm, but recently, authors have advised treatment of all significant aneurysms. We performed a retrospective review for 63 patients with multiple intracranial aneurysms, admitted to Department of Neurosurgery, Kyung-Hee University Hospital between Jun. 1982 and Dec. 1989. The present study includes the incidence of multiple aneurysms, its age and sex distribution, aneurysm locations, probability of rupture, relationship of aneurysmal size and rupture, and operative results. The results were as follows ; 1) Multiple intracranial aneurysms occurred in about 12.2% of all patient with aneurysms. 2) The female to male ratio was about 2.3:1 for patients with two aneurysms and 5:1 for patients with three or more aneurysms. 3) Common location for multiple aneurysms were the PCoA, ICA, ACoA, and MCA. 4) On the distribution of multiple aneurysms according to location, unilateral and midline located mutliple aneurysms were 61.9%. 5) Probability of aneurysmal rupture according to site was(in decreasing order) ACoA, PCoA, AChoA, MCA, and ICA bifurcation. 6) Irregularity of shape was more inportant than size in identifying the site of rupture. 7) Most unruptured aneurysms were 5mm or smaller in size ; however, most ruptured aneurysms were 6mm or larger. 8) About 70% of surgical management showed good and fair result.

The demineralized bone matrix (DBM) as the bone graft material to increase the fusion rate was widely used in spinal fusion. The current study aimed to compare the fusion rate of DBM to the fusion rate of autograft in lumbar spine fusion via meta-analysis of published literature. After systematic search, comparative studies were selected according to eligibility criteria. Checklist (risk of bias assessment tool for non-randomized study) was used to evaluate the risk of bias of the included nonrandomized controlled studies. The corresponding 95% confidence interval (95% CI) were calculated. We also used subgroup analysis to analyze the fusion rate of posterolateral lumbar fusion and lumbar interbody fusion. Eight studies were finally included in this meta-analysis. These eight studies included 581 patients. Among them, 337 patients underwent spinal fusion surgery using DBM (DBM group) and 204 patients underwent spinal fusion surgery with mainly autologous bone and without using DBM (control group). There was no significant differences of fusion rate between the two groups in posterolateral fusion analysis (risk ratio [RR], 1.03; 95% CI, 0.90–1.17; p=0.66) and interbody fusion analysis (RR, 1.13; 95% CI, 0.91–1.39; p=0.27). Based on the available evidence, the use of DBM with autograft in posterolateral lumbar spine fusion and lumbar interbody fusion showed a slightly higher fusion rate than that of autograft alone; however, there was no statistically different between two groups.

The guidelines for chronic obstructive pulmonary disease (COPD) treatment are important for the management of the disease. However, studies regarding the treatment adherence to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines have been scarce in Korea. Therefore, to examine the adherence to the GOLD guidelines, we examined the patterns of prescribed medication in COPD patients from 2011 to 2018. Patients were classified as having been appropriately and inappropriately treated (overtreatment or undertreatment) for the GOLD group. Appropriate medical therapy was defined as using the first choice or alternative choice drug recommended in the GOLD guidelines. Inappropriate therapy was classified as overtreatment or undertreatment in accordance with the categorization in the GOLD guidelines. According to treatment of 2011 GOLD guidelines, there was inappropriate treatment in 52.3% in group A, 47.3% in group B, 56.3% in group C, and 17.8% in group D. According to treatment of 2017 GOLD guidelines, there was inappropriate treatment in 66.7% in group A, 45.3% in group B, 14.3% in group C, and 24.0% in group D. The common type of inappropriate COPD treatment is overtreatment, with inhaled corticosteroid (ICS) containing regimens. In conclusions, adherence to the GOLD guideline by the pulmonologist in clinical practice is still low in Korea. Therefore, we need better strategies to both optimize the use of the guidelines and adhere to the guidelines as well.

OBJECTIVE: The aim of our study was to compare the accuracy of CT and 18F-FDG PET for detecting peritoneal metastasis in patients with gastric carcinoma. MATERIALS AND METHODS: One-hundred-twelve patients who underwent a histologic confirmative exam or treatment (laparotomy, n = 107; diagnostic laparoscopy, n = 4; peritoneal washing cytology, n = 1) were retrospectively enrolled. All the patients underwent CT and 18F-FDG PET scanning for their preoperative evaluation. The sensitivities, specificities and accuracies of CT and 18F-FDG PET imaging for the detection of peritoneal metastasis were calculated and then compared using Fisher's exact probability test (p < 0.05), on the basis of the original preoperative reports. In addition, two board-certified radiologists and two board-certified nuclear medicine physicians independently reviewed the CT and PET scans, respectively. A receiver-operating characteristic curve analysis was performed to compare the diagnostic performance of CT and 18F-FDG PET imaging for detecting peritoneal metastasis. RESULTS: Based on the original preoperative reports, CT and 18F-FDG PET showed sensitivities of 76.5% and 35.3% (p = 0.037), specificities of 91.6% and 98.9% (p = 0.035), respectively, and equal accuracies of 89.3% (p = 1.0). The receptor operating characteristics curve analysis showed a significantly higher diagnostic performance for CT (Az = 0.878) than for PET (Az = 0.686) (p = 0.004). The interobserver agreement for detecting peritoneal metastasis was good (κ value = 0.684) for CT and moderate (κ value = 0.460) for PET. CONCLUSION: For the detection of peritoneal metastasis, CT was more sensitive and showed a higher diagnostic performance than PET, although CT had a relatively lower specificity than did PET.

BACKGROUND: Cancer risk and epidemiology in pre-dialysis chronic kidney disease (CKD) warrant further investigation in a large-scale cohort. METHODS: We performed a nationwide population-based study using the national health insurance database of Korea. We screened records from 18,936,885 individuals who received a national health examination ≥ 2 times from 2009 to 2016. Pre-dialysis CKD was identified based on serum creatinine and dipstick albuminuria results. Individuals with preexisting cancer history, renal replacement therapy, or transient CKD were excluded. A control group without evidence of kidney function impairment and matched for age, sex, low-income status, and smoking history was included. Risk of cancers, as identified in the claims database, was investigated using a multivariable Cox regression model including matched variables and other unmatched clinical characteristics as covariates. RESULTS: A total of 471,758 people with pre-dialysis CKD and the same number of matched controls were included. Urinary (adjusted hazard ratio [HR], 1.97; 95% confidence interval [95% CI], 1.82–2.13) and hematopoietic (adjusted HR, 1.53; 95% CI, 1.38–1.68) malignancy risk was increased in pre-dialysis CKD and all CKD stages. However, the risk of digestive cancer was lower in the pre-dialysis CKD group (adjusted HR, 0.89; 95% CI, 0.87–0.92). The risk of digestive, respiratory, thyroid, and prostate malignancy demonstrated a non-linear association with CKD stage, with stage 1 or stage 4/5 CKD without dialysis demonstrating relatively lower risk. CONCLUSION: Cancer risk varied in pre-dialysis CKD compared to controls, and the association between cancer risk and CKD stage varied depending on the cancer type.
