Duodenal diaphragm is a rare congenital anomaly among the congenital duodenal obstructions. Its symptom and sign usually appear since birth if obstruction is complete. The clinical manifestations of incompletely obstructive duodenal diaphragm are intermittent vomiting, abdominal pain and poor weight gain. Diagnosis may be delayed in this case. Authors experienced a case of incomplete duodenal diaphragm with a central hole. A 29 months old girl presented failure to thrive, intermittent episodes of bloating, abdominal discomfort and occasional vomiting. The patient vomited every 10-14 days, then the abdominal pain and distention were relieved. She overate for about 10 days until the next projectile vomiting. The vomitus frequently contained food ingested several days previously. Plain x-ray films of abdomen showed marked gastric distention. Upper gastrointestinal series revealed marked distention of the duodenum with windsock configuration and radiolucent line at the third portion of the duodenum. On gastroscopic examination, gastric bezoar impacting the pyloric canal and antrum was noted. At operation, we found mucosal membrane in the third portion of the duodenum and bezoar(Chinese cabbage) above the membrane. Side-to-side duodeno-jejunostomy was performed and bezoar was removed. She was discharged on the 13th postoperative day without any complication.

Primary breast lymphoma is a rare malignant breast tumor, accounting for <1% of all breast cancers. Among them, diffuse large B-cell lymphoma is the most common histologic subtype.However, primary mucosa-associated lymphoid tissue (MALT) lymphoma is less common and more indolent than diffuse large B-cell lymphoma, and primary MALT lymphoma of the breast is extremely rare. We report a case of bilateral breast cancer in a 62-year-old woman with primary MALT lymphoma in right braest and contralateral invasive breast cancer in left breast. The patient presented with a palpable right breast lump, which appeared as a noncalcified mass on mammography and an indistinct irregular hypoechoic mass with internal vascularity on breast ultrasonography. The mass was pathologically confirmed by excisional biopsy as primary MALT lymphoma. The patient underwent dynamic contrast-enhanced breast MRI, which additionally detected a small suspicious mass in the left breast. This was a clinically and mammographically occult breast cancer diagnosed as invasive ductal carcinoma.

BACKGROUND: Studies in animals suggest that pipecuronium dose not induce hemodynamic chan-ges related to histamine release or to an effect on the autonomic nervous system. Therefore the effects of bolus administration of large doses of pipecuronium, up to 0.20 mg/kg, on the intubation condition, onset and duration of neuromuscular blockade, heart rate and blood pressure were studied during fentanyl- nitrous oxide anesthesia. METHOD: Forty adults were randomly assigned to receive a bolus injection of either 0.05, 0.10, 0.15, 0.20 mg/kg of pipecuronium. Neuromuscular blockade was measured using mechanomyographic activity of the adductor pollicis muscle after supramaximal stimulation of the ulnar nerve. Four subgroups of 10 patients received pipecuronium doses of 0.05, 0.10, 0.15 and 0.20 mg/kg, respectively, as an intubating dose. RESULTS: The times of onset and clinical duration (mean sem) after each dose were as follows: 0.05 mg/kg, 2.98 0.42 and 41.5 2.42 min; 0.10 mg/kg, 1.54 0.06 and 82.9 7.48 min; 0.15 mg/kg, 1.41 0.14 and 124.8 13.1 min; 0.20 mg/kg, 1.12 0.05 and 187.1 12.8 min. The intubation condition, time of onset and duration after doses of 0.05 mg/kg were significantly different from values after the higer doses. The duration was increased with dose-increments. No dose-related changes in heart rate or blood pressure were observed. CONCLUSION: The authors conclude that dose of 0.10 mg/kg and over has good intubation condition clinically and large bolus dose of pipecuronium can be safely used with a significantly prolonged duration of action without hemodynamic change.

PURPOSE: A charcoal filter attached within the anesthetic circuit has been shown to efficiently adsorb halothane or isoflurane, thus hastening anesthetic recovery in low or minimal flow system. This study was intended to demonstrate whether the charcoal filter enhances the recovery time from sevoflurane anesthesia using a semi-closed circuit system. MATERIALS AND METHODS: Thirty healthy patients scheduled for elective surgery under sevoflurane anesthesia were randomly assigned to the charcoal filter or control group. Upon completion of surgery, the end-tidal concentration of sevoflurane was maintained at 2.0 vol%. A charcoal filter was attached to the expiratory limb of the breathing circuit of charcoal filter group subjects. After sevoflurane was discontinued, ventilation was controlled with the same minute volume as the intra-operative period at a fresh gas flow rate of 5 L.min(-1) with 100% O2. The elimination kinetics of sevoflurane from end-tidal concentration, Bispectral index and times of eye opening and extubation were obtained. RESULTS: The exponential time constant (tau) of alveolar sevoflurane concentration in the charcoal filter group was significantly shorter than that in the control group (1.7+/-0.5 vs. 2.5+/-1.1 min, p=0.008). The charcoal filter hastened rapid eye opening (11.1+/-3.8 vs. 14.8+/-3.0 min, p=0.007) and extubation (11.9+/-3.9 vs. 15.3+/-3.2 min, p=0.014), compared to the control group. CONCLUSION: A charcoal filter enhances the recovery from sevoflurane anesthesia with a semi-closed rebreathing circuit.

BACKGROUND: Long-term phenytoin therapy induces resistance to the neuromuscular blocking effects of metocurine, atracurium, doxacurium, and pipecuronium. This study examine neuromuscu-lar blocking effect and recovery of mivacurium in isolated rat phrenic-hemidiaphragm with two-weeks phenytoin pretreatment. METHOD: After the administration of 14 days of phenytoin 40 mg/kg, administered intraperitoneally twice daily (n=10), ED90, antagonism of neostigmine and 4-aminopyridine on the electrically evoked twitch response and train-of-four (TOF) stimulation were compared to control groups in isolated rat phrenic-hemidiaphragm preparation. RESULTS: ED90 was significantly greater in the phenytoin group than in the control group (319 +/- 39.5 g vs. 209.5 +/- 52.2 g, respectively). After the administration of neostigmine 0.75 M, the recovery of the single twitch and TOF ratio were significantly lesser in the phenytoin group than in the control group (single twitch; 19.6 +/- 6.6% vs. 69.2 +/- 9.4%, TOF ratio; 0.258 +/- 0.149 vs. 0.543 +/- 0.1, respectively). After the administration of 4-aminopyridine 40uM, the recovery of the single twitch and TOF ratio were no significant differrence between the phenytoin group and the control group (twitch; 118.1 +/- 25.3% vs. 122.6 +/- 24.8%, TOF ratio; 0.937 +/- 0.051 vs. 0.949 +/- 0.067, respectively). CONCLUSION: Long-term phenytoin therapy induces resistance to the neuromuscular blocking effects of mivacurium.

Epstein-Barr virus (EBV)-encoded small non-coding RNAs (EBERs) are abundantly expressed in various EBV-associated malignancies, and play critical roles in cell proliferation, tumorigenesis, and apoptosis resistance. However, the mechanism how EBERs regulate cell function awaits further clarification. In this study, we investigated the effect of EBERs on the expression of cellular microRNA (miRNA) and mRNA expression. To test the effect of EBERs while unaffected by other EBV genes, we used EBERs-deleted recombinant EBV infected Burkitt's lymphoma cell line (Akata(+)EBERs(-)) as well as EBV-infected (Akata(+)) and EBV uninfected (Akata(-)) cell lines. They all have the same genetic backgrounds. First, 15 different cellular miRNAs which have reverse complementary sequences to EBERs and have reported targets were selected by bioinformatics analysis. When RT-PCR was carried out for the 16 miRNAs using RNAs from Akata(+), Akata(-), and Akata(+)EBERs(-) cells, hsa-miR-7-5p was the only one showing down-regulated expression in Akata(+) than in Akata(-) and Akata(+)EBERs(-) cells. Bioinformatics and mRNA microarray analyses for Akata(+), Akata(-), and Akata(+)EBERs(-) cell lines were then carried out to predict putative targets of hsa-miR-7-5p. Among the 6 predicted targets of hsa-miR-7-5p, only low density lipoprotein receptor-related protein 6 (LRP6) was up-regulated in EBERs-expressing cells when tested by RT-PCR and Western blot. However, luciferase reporter assay showed that the 3'-UTR of LRP6 was not directly targeted by hsa-miR-7-5p. Our data suggest that both hsa-miR-7-5p and LRP6 are regulated by EBERs in Akata cells, and these genes may partly mediate the tumorigenic function of EBERs in Burkitt's lymphoma.

BACKGROUND: Ruptured aneurysms of sinus of Valsalva are rare cardiac anomaly. Here, we analyze retrospectively patients operated on at our hospital during the last 10 years. METHODS: Seventeen cases of ruptured congenital aneurysm of sinus of Valsalva (female:male=10:7, mean age 33.2+/-15.2 year) were operated during the period of January 1989 through August 1998. A ruptured aneurysm of the sinus of Valsalva was diagnosed by transthoracic 2D echocardiography and multiplane esophageal echocardiography. The diagnoses were confirmed at operation. The majority (94.1%) arose from the right coronary sinus. The right ventricle was the most common chamber of rupture (76.5%). Ventricular septal defect was associated in 13 patients (76.5%), of which 8 (61.5%) were subarterial. Ventricular septal defect was more common in aneurysms arising from the right coronary sinus (81.2%). Aortic regurgitation was found in 5 patients (29.4%). One patient underwent aortic valve repair and one an arotic valve replacement. RESULTS: There was no early operative death and no recurrence after the initial repair. Postoperative morbidities were few. There was one late sudden cardiac death 3 months post-surgery. In the majority, the long-term follow-up was uneventful. CONCLUSION: Surgery for ruptured aneurysm of sinus of Valsalva yields gratifying results, and it should be undertaken as soon as the condition is diagnosed. With recent developments, echocardiography may prove a substitute for cardiac catheterization and angiocardiography in future, and surgery could be undertaken with the help of echocardiography alone.

Antihypertensive effect of angiotensin converting enzyme(ACE) inhibitor Captopril was studied in 34 cases of essential hypertension. A single oral dose of 50mg Captopril was administered daily and blood pressure was followed every 2 weeks. Diuretics were added to patients who responded inadequately after 2 weeks of Captopril single treatment. Alpha-blocker, beta-blocker or calcium channel-blocker was added to patients who responded inadequately after another 2 weeks of Captopril and diuretics combined treatment. In 5 cases, Captopril was raised to 100mg and further antihypertensives were added to unresponded 3 cases. The resuts were as follows; 1) In 15 patients, blood pressure dropped from 170.3+/-10.5mmHg/108.7+/-6.1mmHg to 148.3+/-4.4mmHg/93.3+/-3.7mmHg after 8 weeks of Captopril 50mg single therapy. 2) Hydrochlorothiazide 25mg was added to non-responders, and blood pressure dropped from 180+/-6.7mmHg/111.1+/-6.2mmHg to 155.0+/-15.0mmHg/106.2+/-8.7mmHg in 9 of 19 patients after 8 weeks of combined treatment. 3) Alpha-blocker, Beta-blocker or calcium channel blocker was added to 10 non-responders to Captopril-hyprochlorothiazide combination therapy, and blood pressure dropped from 189.0+/-27mmHg/116+/-10mmHg to 137.8+/-15.5mmHg/88.5+/-10.2mmHg after 8 weeks. 4) Increase of captopril from 50mg to 100mg in 5 random nonresponder cases of Captopril single treatment lowered blood pressure from 168.0+/-13.6mmHg/107.1+/-6.4mmHg to 161+/-15.2mmHg/99+/-8.8mmHg after 2 weeks. 5) Heart rate, and serum creatinine, electrolytes and lipid levels showed no significant interval change. 6) Six patients complained of dry cough and one patient complained of poor appetite but no other clinically significant complications were noted during Captopril treatment.
