Résumé
BACKGROUND/AIMS: Surgical resection or ablation is recommended for the treatment of early hepatocellular carcinoma (HCC), whereas transarterial chemoembolization (TACE) is frequently used in early HCC ineligible for curative resection. We evaluated the clinical effects and safety of radiofrequency ablation (RFA) shortly after TACE in patients with Barcelona clinic liver cancer (BCLC) stage A HCC. METHODS: Sixty-seven BCLC stage A HCC patients who failed to achieve complete response to TACE as either a first line treatment and who subsequently received RFA at the Konkuk University Medical Center from January 2005 to December 2017 were included. Evaluation indices included treatment response, overall survival rate, recurrence-free survival, prognostic factors, and procedure-related complications. RESULTS: Median follow-up was 46.9 months. Fifty-four (80.6%) patients were of Child-Pugh class A, and 13 (19.4%) were of class B. Modified UICC stages were I in 10 (14.9%), II in 46 (68.7%), and III in 11 (16.4%) patients. In the 67 study subjects, cumulative recurrence-free survival rates were 86.8%, 55.9% and 29.7% at 1, 3, and 5 years, respectively, and overall survival rates were 100%, 93.4%, and 83.5% at 1, 3, and 5 years, respectively. Tumor size significantly predicted recurrence. No treatment-related death occurred. CONCLUSIONS: Combination of RFA was an efficient and safe treatment for BCLC stage A HCC patients that failed to achieve complete response to initial TACE. We suggest TACE plus RFA be considered as a curative option for early HCC patients ineligible for curative resection of RFA.

PURPOSE: The purpose of this study is to analyze the effects of demineralized bone matrix on posterolateral lumbar fusion. MATERIALS AND METHODS: From 2009 to 2012, 30 patients who had undergone posterolateral fusions using demineralized bone matrix (group I) and 30 who had received autogenous posterior iliac bone grafts (group II) were investigated. Bone union was determined by evaluating serial simple lumbar radiographs taken during the 24 months after surgery. Bone status was classified according to Lenke's scale and the bone fusion was finally determined by flexion/extension lateral radiographs. We also examined halo signs around the pedicular screws evident on the radiographs, scored back pain using a visual analogue scale (VAS), and Oswestry disability index (ODI) score 2 years after surgery to evaluate clinical status of patients. RESULTS: In group I, 19 patients showed union and 11 patients did not; the values for group II were 22 and 8. These proportions did not differ significantly (p=0.57). Time to union was somewhat shorter in group II (25.3±7.9 weeks), but did not differ significantly from that of group I (p=0.097). No statistical significance in the periscrew Halo count, VAS for back pain, and ODI score was observed between the two groups. CONCLUSION: The union rate after using demineralized bone matrix for lumbar posterolateral fusion is similar to that attained when autogenous bone grafts are employed, and lacks the morbidity associated with such grafts. Thus, demineralized bone matrix is an effective bone graft substitute when posterolateral fusion surgery of the lumbar spine is required.

STUDY DESIGN: Retrospective clinical study. PURPOSE: To assess the diagnostic value of suction drain tip culture in patients undergoing primary posterior spine surgery. OVERVIEW OF LITERATURE: To date, the diagnostic value of suction drain tip culture for predicting surgical site infection (SSI) has not been firmly established in orthopedic or spinal surgery. METHODS: In total, 133 patients who underwent primary posterior spine surgery from January 2013 to April 2015 were included in this retrospective study. Patients diagnosed with infective disease or condition was excluded. The suction drain tip was cut off approximately 5 cm from its far end. The sample was sent to the microbiological laboratory of the hospital for culture analysis. Any signs of infection, such as wound discharge or dehiscence, fever, chills, or chronic pain, were recorded. The culture outcome, identification of bacteria, and postoperative transition of the serum C-reactive protein level were also recorded in all patients. The wounds were followed up for a minimum of 3 months. RESULTS: A positive drain tip culture was found in 48 patients (36.1%), of whom, 6 developed SSI. The sensitivity of drain tip culture for SSI after primary posterior spine surgery was 60.0%, and the specificity was 65.9%. The association between the incidence of positive suction tip culture and SSI was not statistically significant. Among the 48 positive drain tip cultures, there was no significant association between the occurrence of SSI and virulence of isolated bacteria. There was no significant association between drain tip culture positivity and the duration of drainage, or between the rate of SSI and duration of drainage. CONCLUSIONS: Suction drain tip culture analysis is a poor predictor of SSI after primary posterior spine surgery. Routine use of a drain tip culture is not supported by the results of this study.

Immunoglobulin A (IgA) nephropathy associated with cirrhosis is the most common form of secondary IgA nephropathy (IgAN). Cirrhosis-related IgAN is usually clinically silent with a rare occurrence of gross hematuria, unlike in cases of idiopathic IgAN. Especially, acute tubular necrosis (ATN) associated with gross hematuria is very rare in cirrhosis-related IgAN, although acute renal failure is a frequently reported complication in advanced cirrhosis. Herein, we report an unusual case of ATN requiring renal replacement therapy, associated with gross hematuria in a patient with nonalcoholic, hepatitis B virus-associated cirrhosis. Results of a histopathological analysis revealed obstruction of the lumen of renal tubules by red blood cell casts, a marked tubular necrosis, and IgA deposition in the mesangium. The patient's renal function and gross hematuria were clearly improved after lamivudine treatment.

Dermatomyositis (DM) is rare systemic inflammatory disease with typical skin manifestations and muscular involvement. Various skin lesions can accompany this disease, such as Gottron's sign, Heliotrope rash, mechanic's hands, V sign and shawl sign. Scleredema is a very rare skin manifestation in DM. We report a case of DM in a 63-year-old woman, who had scleredema on her thighs. A diagnosis of DM was established by clinical manifestation, elevated muscle enzyme levels, electromyogram measures, and muscle biopsy findings. She was successfully treated with the immunosuppressants methotrexate, cyclosporine, and steroids (low dose).

BACKGROUND: Pneumonia is commonly seen in outpatient clinics. it is widely known as the most common cause of death from infectious disease. Pneumonia has been diagnosed by its typical symptoms, chest X-ray and blood tests. However, both chest X-rays and blood tests have limitations in diagnosis. Thus primary care clinicians usually have been constrained due to a lack of adequate diagnostic tools. Vibration response imaging (VRI) is a newly emerging diagnostic modality, and its procedure is non-invasive, radiation-free, and easy to handle. This study was designed to evaluate the diagnostic usefulness of the VRI test among pneumonia patients and to consider its correlation with other conventional tests such as Chest X-ray, laboratory tests and clinical symptoms. METHODS: VRI was performed in 46 patients diagnosed with pneumonia in Konkuk University Medical Center. VRI was assessed in a private and quiet room twice: before and after the treatment. Sensors for VRI were placed on a patient's back at regular intervals; they detected pulmonary vibration energy produced when respiration occurred and presented as specific images. Any modifications either in chest X-ray, C-reactive protein (CRP), white blood cell count (WBC) or body temperature were compared with changes in VRI image during a given time course. RESULTS: VRI, chest X-ray and CRP scores were significantly improved after treatment. Correlation between VRI and other tests was not clearly indicated among all patients. But relatively severe pneumonia patients showed correlations between VRI and chest X-ray, as well as between VRI and CRP. CONCLUSION: This study demonstrates that VRI can be safely applied to patients with pneumonia.

Cefepime-induced nonconvulsive status epilepticus (NCSE) in end-stage renal disease (ESRD) patients receiving hemodialysis has only rarely been reported. Here we report a case of cefepime-induced NCSE presenting as coma in a patient with ESRD on hemodialysis. A 73-year-old man, who had been receiving maintenance hemodialysis, developed aphasia and coma during cefepime therapy for epidural abscess. Emergent eletroencephalography (EEG) revealed evidence of NCSE. The abnormal EEG findings were resolved and comatose mentality was completely recovered after cessation of cefepime and administration of anticonvulsive drugs. Cefepime-induced NCSE should be considered if neurological symptoms including comatose mentality develops during cefepime therapy in a patient with renal failure.
