Surgical Science 2012年第2期3卷 93-95页

Aim: Chylothorax is a recognized complication after surgery for congenital diaphragmatic hernia (CDH) in a neonate. Management strategies for chylothorax include cessation of enteral feedings, repeated aspiration, chest drainage, and total parenteral nutrition. It is important to determine which is the better plan for treatment of chylothorax after repair of CDH. The authors report successful management by use of the MCT diet for a neonate with chylothorax after repair of CDH. Case: A male infant weighing 3.0 kg was delivered by cesarean section at 38 weeks of gestation and intubated immediately after birth. Prenatal ultrasonography had disclosed left-sided posterolateral diaphragmatic hernia. After stabilization, surgery was performed via a left-sided transverse supra-abdominal incision. The unfixed colon, small bowel, stomach, and spleen were reduced from the chest with little difficulty. A hernia sac was not present and the left-sided posterolateral diaphragm showed a defect 3.5 cm × 2.0 cm in width. The child was fed via a nasogastric tube starting on postoperative day 4 and dyspnea disappeared. Plain chest X-ray on postoperative day 7 showed left pleural radioopacity. A specimen of the chest drainage examined on postoperative day 10 was typical of lymph, with a triglyceride level of 328 mg/dl. The chest drainage was dark yellowish, and a medium-chain triglyceride formula was used until postoperative day 30, by which time the effusion has disappeared. Discussion: Chylothorax after repair of CDH may be a transient disorder that will resolve after a period of diminished flow through the thoracic lymphatics.

Appendical Perforation by Infection with Extended-Spectrum Beta-Lactamase (ESBL)-Producing <i>Escherichia coli</i>: Case Report

引用

Surgical Science 2012年第1期3卷 53-55页

We report the very rare case of a huge appendical abscess with extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (E. coli) as the pathogen. There have been several reports of appendical infections such as appendicitis and appendical abscess caused by ESBL-producing bacteria in adults. The treatment of ESBL-producing E. coli infection is specific, and ESBL-producing bacteria have recently been reported as pathogens associated appendicitis in children. To the best of our knowledge, this is the second report of perforated appendicitis with abscess due to ESBL-producing E. coli. We discuss the diagnostic modalities and treatments for appendical abscess with ESBL-producing E. coli. and propose that the patients with perforated appendicitis and abscess formation due to ESBL-producing E. coli should be administered the antibiotic MEPM within 2 weeks to treat the abscess more effec-tively without producing other multidrug-resistant bacteria.

Can pH Monitoring Predict Gastric Emptying Measured by <sup>13</sup>C-Acetate Breath Test in Gastroesophageal Reflux with Neurological Impairment?

引用

Surgical Science 2014年第1期5卷 20-24页

作者： Tadao Okada Shohei Honda Hisayuki Miyagi masashi minato Akinobu Taketomi Department of Gastroenterological Surgery I Hokkaido University Graduate School of Medicine Sapporo Japan

Introduction: Delayed gastric emptying (DGE) often occurs in patients with gastroesophageal reflux (GER) due to neurological impairment (NI). 13C has been used as an alternative tool for measuring the gastric emptying rates. The aim of this study was to predict gastric emptying in children with GER using 13C-acetate breath test (ABT) by 24-hour pH monitoring. Methods: Nineteen patients were divided into 2 groups: a DGE group with NI (14 patients), and normal-emptying group without NI (5 patients). The liquid test meal consisted of RacolTM (5 ml/kg) mixed with 13C-acetate (50 mg for infants, 100 mg for children, and 150 mg for adolescents). 13CO2 was measured using a gas chromatograph-isotope ratio mass spectrometer. The results are expressed as the % of 13C expired per hour and cumulative 13C excretion over a 3-hour periods including the parameters of half excretion and lag time. Results: The mean half excretion time was 1.762 hour in the DGE group and 1.095 hour in the normal-emptying group (P = 0.0196). The mean lag time was 0.971 hour in the DGE group and 0.666 hour in the normal-emptying group (P = 0.0196). Therefore, DGE was significantly more prevalent in the DGE compared to the normal-emptying group. The percentage of the time when the pH was less than 4 on 24-hour esophageal pH monitoring was 21.6% ± 9.2% in the DGE group and 28.5% ± 11.6% in the normal-emptying group (P = 0.4634). Conclusion: The percentage of time when the pH is less than 4 on 24-hour pH monitoring cannot predict DGE measured by the 13C-ABT in GER.

Elevation of Serum CA-125 in Mucinous Cystadenoma of the Ovary with Torsion: A Rare Occurrence and Review of the Literature

引用

Surgical Science 2011年第10期2卷 499-501页

作者： Tadao Okada Shohei Honda Hisayuki Miyagi masashi minato Kanako C. Kubota Akinobu Taketomi 不详

Aim: Benign neoplasms of the ovary originating from epithelial tissue are common tumors in adult women. They are, however, rarely seen in children or adolescent girls with elevation of serum carbohydrate antigen- 125 (CA-125). The present report describes a rare case of premenarchal women with a giant mucinous cystadenoma (MCA) of the ovary with torsion complicated with elevation of serum CA-125. Case: A 15-year-old, premenarchal, previously healthy girl was referred to our hospital with a 2-week history of left lower abdominal pain. Physical examinations showed a firm and mobile mass with tenderness in the left lower quadrant. Tumor markers showed CA-125 at 124.1 U/ml. An enhanced computed tomography scan showed a multiloculated tumor that was partly solid, compressing the small intestine, uterus, and urinary bladder, but no signs of organ invasion, lymph node swelling, or ascitis. Via a lower transverse incision, the right Fallopian tube was observed to have twisted 1620。 counterclockwise, and a tense cyst measuring 22.0 × 12.0 × 10.5 cm and weighing 1.78 kg was found in the right ovary. Release from torsion and unilateral salpingo-oophorectomy with tumor removal was performed because blood flow to the right Fallopian tube did not improve after torsion release. The histopathological findings showed an MCA of the ovary without cell dysplasia. The patient did not receive adjuvant chemotherapy following surgery. There was no evidence of recurrence at 2 years. Disucussion: We need to consider MCA of the ovary when there is elevation of the serum CA-125 and an ovarian mass.

Variations of Atmospheric ELF/VLF Radio Noise Due to Seismogenic Modifications in Tropospheric Conductivity

引用

Open Journal of Earthquake Research 2024年第2期13卷 113-132页

作者： masashi Hayakawa Alexander P. Nickolaenko Hayakawa Institute of Seismo Electromagnetics Co. Ltd. (Hi-SEM) UEC Alliance Center #521 Tokyo Japan The University of Electro-Communications (UEC) Advanced Wireless & Communications Research Center (AWCC) Chofu-shi Tokyo O.Ya.

We suggest a possible explanation of the influence of pre-seismic activity on the registration rate of natural ELF(extremely low frequency)/VLF(very low frequency) pulses and the changes of their characteristics. The main idea is as follows. The distribution of the electric field around a thundercloud depends on the conductivity profile of the atmosphere. Quasi-static electric fields of a thundercloud decrease in those tropospheric regions where an increase of air conductivity is generated by pre-seismic activities due to emanation of radioactive gas and water into the lower atmosphere. The electric field becomes reduced in the lower troposphere, and the probability decreases of the cloud-to-ground (CG) strokes in such “contaminated” areas. Simultaneously, the electric field grows inside and above the thunderclouds, and hence, we anticipate a growth in the number of horizontal and tilted inter-cloud (or intra-cloud) (both termed as IC discharges) strokes. Spatial orientation of lightning strokes reduces vertical projection of their individual amplitudes, while the rate (median number strokes per a unit time) of discharges grows. We demonstrate that channel tilt of strokes modifies the spectral content of ELF/VLF radio noise and changes the rate of detected pulses during the earthquake preparation phase.
