A 39-year-old Korean man with general malaise was found to have two hepatic cysts by computed tomography. He had the history of close contact with domesticated wild dog in Saudi Arabia in 1976. Two cysts, 15cm and 10cm in diameter which contained clear fluid, were excised from both lobes of the liver. He was pathologically diagnosed as unilocular hydatid disease. This case is regarded as an imported case from Saudi Arabia.

The authors recovered a white thread-like living nematode in left conjunctival sac of a 33 years old male on May 29, 1981. The chief complaints were foreign body sensation and itching sensation of eye. The worm was a female measuring 12.1 mm in length and 0.171 mm in maximum width. It was identified as Thelazia callipaeda Railliet et Henry, 1910. And we recorded the patient as the 10th reported thelaziasis case in Korea.

PURPOSE: Implementing an inferior vena cava (IVC) filter is a relatively safe procedure but potential negative long-term effects. The complications for filter retrieval have been noted. We examined filter characteristics on pre-retrieval computed tomography (CT) that were associated with complicated retrieval (CR) of IVC filters. MATERIALS AND METHODS: A retrospective review of IVC filter retrievals between January 2008 and June 2014 was performed to identify patients who had undergone a pre-retrieval CT for IVC filter retrieval. CR was defined as the use of nonstandard techniques, procedural time over 30 min, filter fractures, filter tip incorporation into the IVC wall, and retrieval failure. Pre-retrieval CT images were evaluated for tilt angle in the mediolateral and anteroposterior directions, tip embedding into the IVC wall, degree of filter strut perforation, and distance of the filter tip from the nearest renal vein. RESULTS: Of seventy-six patients, twenty-four patients (31.6%) with CRs and 56 patients (73.7%) with non-CR were evaluated for pre-retrieval CT. For IVC filter retrieval with a dwelling time of over 45 days, a tilt of over 15 degrees, the appearance of tip embedding and grade 2 perforation were associated with CR on multivariate analysis. However, for IVC filter retrievals with a dwelling time of less than 45 days, there were no factors associated with CR. CONCLUSION: Pre-retrieval CTs may be more effective for IVC filters with a dwelling time of over 45 days. Therefore, a pre-retrieval CT may be helpful in predicting CR of IVC filters with long dwelling times.

Myocardial involvement by a lung neoplasm rarely appears, on an ECG, mimicking acute myocardial infarction. We experienced a case of metastatic lung cancer, to the cardiac apex, showing persistent ST segment elevation in the precordial leads, which simulated an acute anterior myocardial infarction.

Posttraumatic high-flow communications between the intracavernous internal carotid artery (ICA) and the cavernous sinus may give rise to two different pathological entities. A connection from the intracavernous ICA system can theoretically connect with two different structures; the vein of the plexus (CCF) or the perivascular bare spaces between the veins (pseudoaneurysm). A CCF and a pseudoaneurysm can be present in the same patient. A 24-year-old man was admitted to our hospital due to sudden mental deterioration. Carotid angiography revealed a CCF, which had occurred after a trauma 5 years earlier, associated with left visual disturbance and skull base fractures. The treatment of choice was permanent coil occlusion of the intracavernous ICA at the level of the lesion. The collateral circulation was evaluated before the endovascular treatment using a balloon test occlusion (BTO). During the BTO, adequate collateral circulation was defined as symmetric angiographic filling of both hemispheres. A continuous neurological examination was performed during the procedure. The follow-up angiography showed a persistent aneurysm occlusion. We report our experience of the successful endovascular treatment of combined lesions with a review of the relevant literature.

PURPOSE: Totally implantable venous access devices (TIVADs) are commonly used in pediatrics for the administration of chemotherapy, antibiotics, or parenteral nutrition. TIVADs can be implanted using various techniques, including surgical cutdown (SC) and percutaneous puncture (PP). Recently, percutaneous TIVAD became popular in adults, but studies comparing between PP and SC group in pediatric patients are rare. MATERIALS AND METHODS: Data were collected and analyzed retrospectively from 23 patients who underwent TIVAD at a single institution between January 2013 and December 2015. We examined the clinical characteristics, insertion techniques, and clinical outcome. We divided the patients into 2 groups and compared PP with ultrasonography and SC using the insertion technique. We compared success rate, procedural time, and the patency rate between the 2 groups. RESULTS: Eleven TIVADS were inserted using PP, and 12 TIVADs were inserted using SC. No statistically significant difference in characteristics was found between the 2 groups. The procedural time in the PP group was shorter than that in the SC group, but the difference was not statistically significant (P=0.685). During follow-up, 1 patient in the SC group had an occlusion, and 1 patient in the PP group had an infection. CONCLUSION: PP of the internal jugular vein with ultrasonography appears to be the method of choice for TIVAD insertion owing to its similar success rate in terms of implantation and complication rate to that in SC, with shorter procedural times in pediatric patients.

BACKGROUND/AIMS: Lamivudine (LAM) plus adefovir (ADV) combination therapy has been accepted as one of the best treatments for LAM-resistant chronic hepatitis B (CHB). The aim of this study was to determine the efficacy of this combination therapy in hepatocellular carcinoma (HCC) patients. METHODS: The medical records of CHB patients who developed LAM resistance and were treated with LAM plus ADV combination therapy for more than 6 months were reviewed. Their virological response (VR; undetectable HBV DNA) and biochemical response (BR; alanine aminotransferase normalization) were evaluated, and the findings of HCC and non-HCC patients were compared. RESULTS: The data from 104 patients (19 with HCC and 85 without HCC) were analyzed. The VR rates did not differ significantly between the HCC and non-HCC groups: 33.3% vs. 55.6% at 12 months (P=0.119), 58.3% vs. 67.2% at 24 months (P=0.742), 50% vs. 69.8% at 36 months (P=0.280), and 66.7% vs. 71.0% at 48 months (P=1.000). The BR rates also did not differ significantly between the groups: 55.6% vs. 84.0% at 12 months (P=0.021), 58.3% vs. 83.8% at 24 months (P=0.057), 70.0% vs. 77.8% at 36 months (P=0.687), and 66.7% vs. 80.6% at 48 months (P=0.591). CONCLUSIONS: The efficacy of LAM plus ADV combination therapy is comparable in HCC and non-HCC patients.

Compared with iron dextran, iron chondroitin sulfate(ICS) is much cheaper and has better bioavailability. To evaluate the efficacy and safety of ICS in maintenance HD patients, i.v. ICS was given to 37 HD patients [20 M, 17 F, median age 51 years, median duration of HD 21 months] whose ferritin(Fer)< 100microgram/L or transferrin saturation(TFS) <20% [Group I , 12 M, 10 F] or Hb<9.0g/dL in spite of increased rHuEPO dose, Fer>or=100microgram/L and TFS>or=20% [Group II, 8 M, 7 F]. The patients had taken oral iron [227+/-73mg/day(mean+/-SD)] before this study. All patients received 120mg i.v. ICS weekly for 1 month. Then, ICS dosage was adjusted to 40-120mg/week depending on Hb, Fer and TFS in the following 3 months. Hb, Fer, TFS, rHuEPO dose and side effects were monitored monthly. The results were as follows : 1) I.v. iron therapy produced a significant rise in Hb(8.3+/-0.9g/dL to 9.7+/-0.9g/dL; P<0.01), a significant reduction in rHuEPO dose(95+/-50U/kg/wk to 69+/-28U/kg/wk; P<0.05), a significant increase in serum ferritin levels(162+/-149microgram/L to 472+/-255microgram/L; P<0.01) and TFS(24+/-13% to 41+/-18%; P<0.05). 2) In group 1, i.v. iron therapy produced a significant rise in Hb(8.5+/-1.1g/dL to 9.9+/-0.9g/dL; P< 0.01), a significant reduction in rHuEPO dose(87+/-45U/kg/wk to 69+/-27U/kg/wk; P<0.05), increased serum ferritin levels(90+/-48microgram/L to 379+/-186microgram/L; P<0.01) and TFS(18+/-9% to 36+/-16%; P<0.05). 3) In group 2, i.v. iron therapy produced a significant rise in Hb(8.1+/-0.6g/dL to 9.3+/-0.9g/dL; P<0.01), a significant reduction in rHuEPO dose(108+/-55U/kg/ wk to 69+/-31U/kg/wk; P<0.05) and increased serum ferritin levels(274+/-185microgram/L to 602+/-287microgram/L; P< 0.01) with a tendency of increase in TFS(35+/-13% to 41+/-18%; P=0.06). 4) No significant side effect was observed. 5) An annual cost reduction of 221 US dollars per patient was expected. In conclusion, ICS is an effective and safe intravenous iron preparation in HD patients.
