Background and Objectives: Outcomes of deferring percutaneous coronary intervention (PCI) without invasive physiologic assessment for intermediate coronary lesions is uncertain.We sought to compare long-term outcomes between medical treatment and PCI of intermediate lesions without invasive physiologic assessment. Methods: A total of 899 patients with intermediate coronary lesions between 50% and 70% diameter-stenosis were randomized to the conservative group (n=449) or the aggressive group (n=450). For intermediate lesions, PCI was performed in the aggressive group, but was deferred in the conservative group. The primary endpoint was major adverse cardiac events (MACE, a composite of all-cause death, myocardial infarction [MI], or ischemia-driven any revascularization) at 3 years. Results: The number of treated lesions per patient was 0.8±0.9 in the conservative group and 1.7±0.9 in the aggressive group (p=0.001). At 3 years, the conservative group had a significantly higher incidence of MACE than the aggressive group (13.8% vs. 9.3%; hazard ratio [HR], 1.49; 95% confidence interval [CI], 1.00–2.21; p=0.049), mainly driven by revascularization of target intermediate lesion (6.5% vs. 1.1%; HR, 5.69; 95% CI, 2.20–14.73;p<0.001). Between 1 and 3 years after the index procedure, compared to the aggressive group, the conservative group had significantly higher incidence of cardiac death or MI (3.2% vs.0.7%; HR, 4.34; 95% CI, 1.24–15.22; p=0.022) and ischemia-driven any revascularization. Conclusions For intermediate lesions, medical therapy alone, guided only by angiography, was associated with a higher risk of MACE at 3 years compared with performing PCI, mainly due to increased revascularization.

BACKGROUND AND OBJECTIVES: There are no data comparing clinical outcomes of complex percutaneous coronary intervention (PCI) between biodegradable polymer-biolimus-eluting stents (BP-BES) and durable polymer-everolimus-eluting stents (DP-EES). We sought to evaluate the safety and efficacy of BP-BES compared with DP-EES in patients undergoing complex PCI. METHODS: Patients enrolled in the SMART-DESK registry were stratified into 2 categories based on the complexity of PCI. Complex PCI was defined as having at least one of the following features: unprotected left main lesion, ≥2 lesions treated, total stent length >40 mm, minimal stent diameter ≤2.5 mm, or bifurcation as target lesion. The primary outcome was target lesion failure (TLF), defined as a composite of cardiac death, target vessel-related myocardial infarction (TV-MI), or target lesion revascularization (TLR) at 2 years of follow-up. RESULTS: Of 1,999 patients, 1,145 (57.3%) underwent complex PCI: 521 patients were treated with BP-BES and 624 with DP-EES. In propensity-score matching analysis (481 pairs), the risks of TLF (3.8% vs. 5.2%, adjusted hazard ratio [HR], 0.578; 95% confidence interval [CI], 0.246–1.359; p=0.209), cardiac death (2.5% vs. 2.5%, adjusted HR, 0.787; 95% CI, 0.244–2.539; p=0.689), TV-MI (0.5% vs. 0.4%, adjusted HR, 1.128; 95% CI, 0.157–8.093; p=0.905), and TLR (1.1% vs. 2.9%, adjusted HR, 0.390; 95% CI, 0.139–1.095; p=0.074) did not differ between 2 stent groups after complex PCI. CONCLUSIONS: Clinical outcomes of BP-BES were comparable to those of DP-EES at 2 years after complex PCI. Our data suggest that use of BP-BES is acceptable, even for complex PCI.

Biphenotypic acute leukemia (BAL) is a rare type of leukemia, comprises 4% of all acute leukemias. It is more common in adults and the clinical features, as related to marrow dysfunction, are similar to those found in other patients with acute leukemia. BAL commonly shows a dimorphic blast population with, one resembling lymphoblasts and the other resembling myeloblasts. The majority of BAL patients express B-lymphoid and myeloid markers. BAL can be diagnosed by morphologic studies and by a comprehensive panel of immunological markers, as well as cytogenetic/molecular studies, such as fluorescence in situ hybridization (FISH) and reverse transcriptase-polymerase chain reaction (RT-PCR). In addition, its prognosis is relatively poor. We present here a 27 year-old female patient who showed lymphoblasts and myeloblasts on her marrow studies and these cells were positive for myeloid and B-lymphoid markers on the immunophenotypic studies. Chromosome analysis revealed 46,XX,t(6;19)(p23;p13.1),t(9;22)(q34;q11.2). A major (b3a2) type of BCR-ABL1 mRNA transcript was detected by RT-PCR, and a 5'ABL1 deletion was identified by FISH.

Inguinal hernia is the most common disease treated by the pediatric surgeon. There are several controversial aspects of management 1)the optimal timing of surgical repair, especially for preterm babies, 2)contralateral groin exploration during repair of a clinically unilateral hernia, 3)use of laparoscope in contralateral groin exploration, 4)timing of surgical repair of cord hydrocele, 5)perioperative pain control, 6)perioperative management of anemia. In this survey, we attempted to determine the approach of members of KAPS to these aspects of hernia treatment. A questionnaire by e-mail or FAX was sent to all members. The content of the questionnaire were adapted from the "American Academy of Pediatrics (AAP) Section on Surgery hernia survey revisited (J Pediatr Surg 40, 1009-1014, 2005)". For full-term male baby, most surgeons (85.7 %) perform an elective operation as soon as diagnosis was made. For reducible hernia found in ex-preterm infants already discharged from the neonatal intensive care unit (NICU), 76.2 % of surgeons performed an elective repair under general anesthesia (85.8 %). 42.9 % of the surgeons performed the repair just before discharge. For same-day surgery for the ex-premature baby, the opinion was evenly divided. For an inguinal hernia with a contralateral undescended testis in a preterm baby, 61.9 % of surgeons choose to 'wait and see' until 12 month of age. The most important consideration in deciding the timing of surgery of inguinal hernia in preterm baby was the existence of bronchopulmonary dysplasia (82.4 %), episode of apnea/bradycardia on home monitoring (70.6 %). Most surgeons do not explore the contralateral groin during unilateral hernia repair. Laparoscope has not been tried. Most surgeons do not give perioperative analgesics or blood transfusion.

To report cases of metastasectomy for metastatic gynecologic malignancies, we reviewed the medical records of all patients who have undergone metastasectomy for metastatic gynecologic malignancies in Center for Uterine Cancer from June 2001 to October 2002. Six patients were identified with median age of 55 years (range 52-66 years). The metastatic sites and primary sites were as follows: 3 liver metastasis from ovary; 1 abdominal wall metastasis from uterus (endometrial cancer), 1 brain metastasis from ovary, 1 lung metastasis from uterus (sarcoma). The median disease free interval was 48 months (range 10 months-13 years). There was no perioperative mortality. Postoperative morbidity was tolerable with 1 case of bile leakage. In three patients with hepatectomy, one patient was dead of disease after 15 months, one patient is alive with disease at 20 months of follow up, one patient have no evidence of recurrence at 7 months follow up. The patient with brain metastasis was dead due to lung metastsis after 9 months later postoperatively. Remaining two patients with abdominal wall and lung metastasis have no evidence of tumor recurrence at 4, 7 months follow up respectively. Metastasectomy for metastatic gynecologic malignancies can be performed safely and may help prolong survival in carefully selected patients.

BACKGROUND AND OBJECTIVES: The pulsed wave Doppler echocardiography in the mitral inflow is used widely for the assessment of LV diastolic function. The echocardiographic index of LV diastolic function is known to be affected by several factors, such as the loading condition. In the Doppler tissue image (DTI), the mitral annulus velocity is known to be unaffected by the loading condition. The purpose of this study was to investigate the effect of the preload reduction on the mitral annulus velocity. SUBJECTS AND METHODS: We examined the transmitral and pulmonary venous flows, and the mitral annulus velocity in 30 patients with chronic renal failure, but a normal LV systolic function, by echocardiography, both before and after hemodialysis. The study patients were divided into two groups; Group I (preload reduction < or = 2.0 kg, N=10) and Group II (preload reduction>2.0 kg, N=20). RESULTS: In the transmitral flow; the E velocity was changed, both before and after hemodialysis, in Group II. < Group I from 97+/-12 cm/s to 86+/-11 cm/s (NS), Group II from 85+/-5 cm/s to 63+/-5 cm/s (p=0.0001)<. The A velocity was also changed in Group II. In the mitral septal annulus velocity by DTI; The E' velocity was changed in both groups, but the A' velocity was only changed in Group II. In the mitral lateral annulus velocity by DTI; all indices remained unchanged in both groups. CONCLUSION: These results suggested that a vigorous preload reduction might change the echocardiographic indices, and either the transmitral flow pattern or the mitral septal annulus velocity. The mitral lateral annulus velocity indices, which are useful for the evaluation of the LV diastolic function, were unchanged by the preload reduction. The preload condition needs to be accounted for when evaluating the LV diastolic function with a Doppler echocardiography.
