Cost-Effectiveness of Endovascular Thrombectomy in Childhood Stroke: An Analysis of the Save ChildS Study / 대한뇌졸중학회지

Background@#and Purpose The Save ChildS Study demonstrated that endovascular thrombectomy (EVT) is a safe treatment option for pediatric stroke patients with large vessel occlusions (LVOs) with high recanalization rates. Our aim was to determine the long-term cost, health consequences and cost-effectiveness of EVT in this patient population. @*Methods@#In this retrospective study, a decision-analytic Markov model estimated lifetime costs and quality-adjusted life years (QALYs). Early outcome parameters were based on the entire Save ChildS Study to model the EVT group. As no randomized data exist, the Save ChildS patient subgroup with unsuccessful recanalization was used to model the standard of care group. For modeling of lifetime estimates, pediatric and adult input parameters were obtained from the current literature. The analysis was conducted in a United States setting applying healthcare and societal perspectives. Probabilistic sensitivity analyses were performed. The willingness-to-pay threshold was set to $100,000 per QALY. @*Results@#The model results yielded EVT as the dominant (cost-effective as well as cost-saving) strategy for pediatric stroke patients. The incremental effectiveness for the average age of 11.3 years at first stroke in the Save ChildS Study was determined as an additional 4.02 lifetime QALYs, with lifetime cost-savings that amounted to $169,982 from a healthcare perspective and $254,110 when applying a societal perspective. Acceptability rates for EVT were 96.60% and 96.66% for the healthcare and societal perspectives. @*Conclusions@#EVT for pediatric stroke patients with LVOs resulted in added QALY and reduced lifetime costs. Based on the available data in the Save ChildS Study, EVT is very likely to be a cost-effective treatment strategy for childhood stroke.

Gelatinous Transformation of Bone Marrow Mimicking Malignant Marrow-Replacing Lesion on Magnetic Resonance Imaging in a Patient without Underlying Devastating Disease

Gelatinous transformation of bone marrow is characterized by hypoplasia of fat cells with focal loss of hematopoietic cells and deposition of extracellular gelatinous substances. It is known to be associated with devastating underlying diseases that starve bone marrow. Here, we present a case of a patient whose magnetic resonance (MR) imaging findings of vertebral column were interpreted as metastasis or hematologic malignancy, however, the final diagnosis revealed a gelatinous transformation of bone marrow. This is the first report of gelatinous transformation of bone marrow without evidence of underlying devastating disease.

Validation of interphase fluorescence in situ hybridization (iFISH) for multiple myeloma using CD138 positive cells

BACKGROUND: Multiple myeloma is a plasma cell neoplasm with acquired genetic abnormalities of clinical and prognostic importance. Multiple myeloma differs from other hematologic malignancies due to a high fraction of low proliferating malignant plasma cells and the paucity of plasma cells in bone marrow aspiration samples, making cytogenetic analysis a challenge. An abnormal karyotype is found in only one-third of patients with multiple myeloma and interphase fluorescence in situ hybridization is the most useful test for studying the chromosomal abnormalities present in almost 90% of cases. However, it is necessary to study the genetic abnormalities in plasma cells after their identification or selection by morphology, immunophenotyping or sorting. Other challenges are the selection of the most informative FISH panel and determining cut-off levels for FISH probes. This study reports the validation of interphase fluorescence in situ hybridization using CD138 positive cells, according to proposed guidelines published by the European Myeloma Network (EMN) in 2012. METHOD: Bone marrow samples from patients with multiple myeloma were used to standardize a panel of five probes [1q amplification, 13q14 deletion, 17p deletion, t(4;14), and t(14;16)] in CD138+ cells purified by magnetic cell sorting. RESULTS: This test was validated with a low turnaround time and good reproducibility. Five of six samples showed genetic abnormalities. Monosomy/deletion 13 plus t(4;14) were found in two cases. CONCLUSION: This technique together with magnetic cell sorting is effective and can be used in the routine laboratory practice. In addition, magnetic cell sorting provides a pure plasma cell population that allows other molecular and genomic studies.

Imaging Findings of Renal Cell Carcinoma Associated with Xp11.2 Translocation/TFE3 Gene Fusion in a 4-Year-Old Male: Case Report and Review of Literature

We represent a pathologically proven case of a four-year-old male patient with renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusion, which is rare but more frequent in children or young adults. Computed tomography showed about 2.5 cm size ill-defined mass in the right kidney. The mass was hyperechoic on ultrasound. Magnetic resonance imaging demonstrated a mass with capsular enhancement and diffusion restriction. We present a case of Xp11.2 renal cell carcinoma and provide review of the literature.

Papillary Carcinoma Arising from the Pyramidal Lobe of the Thyroid

The authors present a rare case of papillary carcinoma arising from the pyramidal lobe of the thyroid in a 54-year-old woman, who presented with a right submental palpable mass. An ultrasound evaluation depicted a 3 cm mixed echoic mass from the thyroid cartilage level without a focal lesion in the thyroid gland. Surgical specimens obtained during bilateral thyroidectomy confirmed papillary carcinoma of the pyramidal lobe. To the authors' knowledge, this is the first case report to describe papillary carcinoma arising from the pyramidal lobe of the thyroid gland.

Lymphocytic Thyroiditis Presenting as a Focal Uptake on 18F-Fluorodeoxyglucose Positron Emission Tomography: A Case Report

Diffuse increased uptake on (18)F-Fluorodeoxyglucose Positron Emission Tomography ((18F)FDG PET) is a well-known finding of the lymphocytic thyroiditis. Nevertheless, a pathologic confirmation is needed in cases of a focal (18F)FDG uptake in the thyroid gland. This article reports a rare case of a focal (18F)FDG uptake lesion by PET, which was revealed pathologically to be lymphocytic thyroiditis.

Parkinsonism Associated with Glucocerebrosidase Mutation

BACKGROUND: Gaucher's disease is an autosomal recessive, lysosomal storage disease caused by mutations of the beta-glucocerebrosidase gene (GBA). There is increasing evidence that GBA mutations are a genetic risk factor for the development of Parkinson's disease (PD). We report herein a family of Koreans exhibiting parkinsonism-associated GBA mutations. CASE REPORT: A 44-year-old woman suffering from slowness and paresthesia of the left arm for the previous 1.5years, visited our hospital to manage known invasive ductal carcinoma. During a preoperative evaluation, she was diagnosed with Gaucher's disease and double mutations of S271G and R359X in GBA. Parkinsonian features including low amplitude postural tremors, rigidity, bradykinesia and shuffling gait were observed. Genetic analysis also revealed that her older sister, who had also been diagnosed with PD and had been taking dopaminergic drugs for 8-years, also possessed a heterozygote R359X mutation in GBA. 18F-fluoropropylcarbomethoxyiodophenylnortropane positron-emission tomography in these patients revealed decreased uptake of dopamine transporter in the posterior portion of the bilateral putamen. CONCLUSIONS: This case study demonstrates Korean familial cases of PD with heterozygote mutation of GBA, further supporting the association between PD and GBA mutation.

Efficacy of Imatinib Mesylate Neoadjuvant Treatment for a Locally Advanced Rectal Gastrointestinal Stromal Tumor

Surgery is the standard treatment for a primary gastrointestinal stromal tumor (GIST); however, surgical resection is often not curative, particularly for large GISTs. In the past decade, with imatinib mesylate (IM), management strategies for GISTs have evolved significantly, and now IM is the standard care for patients with locally advanced, recurrent or metastatic GISTs. Adjuvant therapy with imatinib was recently approved for use, and preoperative imatinib is an emerging treatment option for patients who require cytoreductive therapy. IM neoadjuvant therapy for primary GISTs has been reported, but there is no consensus on the dose of the drug, the duration of treatment and the optimal time of surgery. These are critical because drug resistance or tumor progression can develop with a prolonged treatment. This report describes two cases of large rectal malignant GISTs, for which a abdominoperineal resection was initially anticipated. The two patients received IM preoperative treatment; we followed-up with CT or magnetic resonance imaging to access the response. After 9 months of treatment, a multi-disciplinary consensus that maximal benefit from imatinib had been achieved was reached. We determined the best time for surgical intervention and successfully performed sphincter-preserving surgery before resistance to imatinib or tumor progression occurred. We believe that a multidisciplinary team approach, considerating the optimal duration of therapy and the timing of surgery, is required to optimize treatment outcome.

Evaluation of Intratumoral HER-2 Heterogeneity by Fluorescence In Situ Hybridization in Invasive Breast Cancer: A Single Institution Study

This study aimed to determine the incidence and characteristics of HER-2 gene heterogeneity in invasive breast cancer in a single institution. Included were 971 cases of primary invasive breast cancer diagnosed between 2008 and 2010. Fluorescence in situ hybridization (FISH) image files were retrospectively reviewed and HER-2 gene heterogeneity was defined as more than 5% but less than 50% of analyzed invasive tumor cells with a HER-2/Chr17 ratio higher than 2.2, according to the College of American Pathologists guidelines. HER-2 gene heterogeneity was identified in 24 (2.5%) cases. The mean proportion of invasive tumor cells with a HER-2/chromosome 17 ratio higher than 2.2 was 11.6% (range: 5%-25%). Of 24 cases, HER-2 gene status was not amplified in 8, showed borderline amplification in 2, and amplification in 14. All HER-2 amplification cases were low-grade. In conclusion, HER-2 gene heterogeneity of invasive breast cancer is identified in routine FISH examination. This may affect the results of HER-2 gene amplification status in FISH studies.

ANCA-associated Vasculitis after Scrub Typhus / 감염과화학요법

Anti-neutrophilic cytoplasmic antibody (ANCA)-associated vasculitis is a primary systemic vasculitis that affects the small vessels, and ANCA is involved as the common pathogenesis. Environmental factors such as infectious agents have been considered to play a role in triggering the autoimmunity. We report here on a case of ANCA-associated vasculitis that developed after scrub typhus. A 64-year-old male was admitted because of fever, chills, pain, weakness and hypoesthesia of his calves. He was diagnosed as having scrub typhus based on the findings of an eschar and the positive serum anti-orientia antibody. The fever continued despite the antibiotic treatment. Neurologic symptoms such as numbness, hypoesthesia and weakness began to develop in the hands, feet and calves with a persisting fever. The nerve conduction velocity study revealed mononeuritis multiplex of the superficial peroneal nerve and the median nerve. Microscopic hematuria then additionally developed, and the serology showed a positive myeloperoxidase (MPO) test. A nerve biopsy was conducted on the left superficial peroneal nerve and the result showed non-infectious systemic vasculitis of the medium-small arteries. He was diagnosed as having microscopic polyangiitis along with ANCA associated vasculitis. The fever resolved and the neurologic symptoms began to improve after steroid pulse treatment (methylprednisolone 1 g/day). The neuropathy gradually improved after discharge. We presume that the ANCA-associated vasculitis was triggered by scrub typhus.

Primary Intradural Extramedullary Malignant Melanoma in the Thoracic Spine: Case Report and Literature Review

We present a case of primary malignant melanoma of the thoracic spine mimicking intradural extramedullary meningioma or schwannoma. In 2010, a 55-year-old man presented with hypesthesia below the T4 dermatome level and bilateral leg weakness. Magnetic resonance imaging (MRI) of the thoracic spine revealed an approximately 1.5 cm well marginated mass lesion in the intradural extramedullary area at the level of T4-5. Preoperative MRI findings suggested benign spinal cord tumor such as meningioma or calcified schwannoma. Surgery revealed a well marginated black-colored tumor. After removal of the tumor, we observed pigmented seeding along the leptomeninges. According to the pathology report, the final diagnosis was malignant melanoma. No evidence of primary malignant tumor, abnormal lymphadenopathy or distant metastatic lesion was found on the PET-CT scan. As a result, the lesion was compatible with primary spinal malignant melanoma. Even if spinal melanoma was suspected in the thoracic spine, it is easy to simply diagnosis the finding as schwannoma or meningioma based on the preoperative radiological findings. Therefore, preoperative diagnosis should be decided carefully, especially for masses in the thoracic spinal tumor.

Is the Use of Physician Reminder Sticker on Medical Records Effective for Improving the Rate of Recommending Influenza Vaccination?

BACKGROUND: For people who have high risk diseases or who are aged 65 years or more, routine influenza vaccination is required. However, in Korea, influenza vaccination rate of such people is low. We performed a study to assess the effectiveness of physician reminder in improving the rate of recommending influenza vaccination. METHODS: Among the patients who registered to tertiary care hospital family clinic center, 305 patients with diabetes mellitus or aged 65 years or more were randomly assigned into physician reminder group and control group. After excluding the patients who were vaccinated before the medical consultation or who did not attend the clinic, remaining 253 patients were included as final study subjects. For the physician reminder group, a sticker showing that influenza vaccination was needed was placed on each medical record. Demographic and clinical characteristics, recommendation of vaccination by physician, and the receipt of vaccination were checked through self-administered questionnaires, review of medical chart and order communication system, and telephone interview. RESULTS: The rates of recommending vaccination in the physician reminder group and the control group were 36% and 29.7%, respectively. The difference between the two groups was not significant. Vaccination rate in patients for whom influenza vaccination was recommended by their physician was 87.0%, whereas those for whom vaccination was not recommended was only 41.2%. CONCLUSION: Physician reminder for influenza vaccination was not effective in this study. However, the physician's recommendation was effective in improving the influenza vaccination rate. Effective strategies will be needed to encourage physicians to recommend influenza vaccination.

Effects of estrogen on somatotropes in the rat pituitary culture / 대한해부학회지

Although somatotropes of the pituitary gland which secret growth hormone occupy the highest percentage among pituitary hormone cells, the regulatory mechanism of the somatotropes has not been investigated as much as that of the mammotropes. The present study was performed to investigate the direct effects of estrogen on the somatotropes after estrogen treatment in culture of rat pituiary cells. Quantification of bromodeoxyuridine (BrdU)-labeled cells after double immunocytochemistry for BrdU and growth hormone (GH) or prolactin (PRL) demonstrated that estrogen treatment did not bring about the difference in either BrdU labeling index (BLI), apoptosis or cell number of somatotropes. In comparison, estrogen increased the BLI and relative cell number of mammotropes. It was suggested that the changes in the relative cell number of the somatotropes or mammotropes do not attribute to cell death, but to cell proliferation.

Preferred place of death of elderly women in seoul

BACKGROUND: The present it is getting to be on aged society there is increasing that hospital has higher rate for place of death than home. Because we can expect that many patients who are faced with death come to hospital or hospice in the future, we have studied preferred place of death with an old women in seoul to have essential material of plan to understand asking for medical service of death, to divide medical manpowers and equipments and to supplement and to revise of medical educations. METHODS: Through the internet, 71 schools for the elderly. Of 277 an old woman who attending the schools out of 7 schools. We research into preferred place of death by self answering way through the June to July in 2000. RESULTS: The average age was 72.4 years. Of 277 respondents, 87 respondents(32.46%) reply their homes as a place of death and 166(61.94%) reply hospital, 15(5.6%) reply hospice, missing is 9. Statistical significance has connections with only level of education. The highest reason(47.5%) why respondents choose the hospital or hospice is only to reduce their children's burdens. Unlike respondents that education attending period is below 6 year, the relative risk of choosing the hospital or hospice between respondents who are 6 9year and above 9 year is each of 3.66, 5.58. CONCLUSION: This research shows that an elderly women in seoul prefer hospitals or hospice to homes as their place of death.
