Some reports have indicated that trisomy 3 represents a characteristic chromosomal abnormality found in lymphomas arising in mucosa-associated lymphoid tissues (MALT)/extranodal marginal zone B-cells (MZBC). Traditional cytogenetic analysis of metaphase preparations is cumbersome and not always possible, especially in those situations in which the diagnosis in not suspected before a biopsy. Our aim is to use a relatively simple method to evaluate trisomy 3 in paraffin-embedded, formalin-fixed tissue, using fluorescence in situ hybridization (FISH) on intact tissue sections. Formalin-fixed, paraffin-embedded archival tissues from 30 cases (27 lymphoma and 3 chronic gastritis cases) were hybridized with a chromosome 3 specific alpha-satellite probe (ONCOR, Gaithersburg, MD). Three of four cases of gastric MZBC/MALT lymphoma revealed trisomy 3. Ten cases of lymphoma of possible or probable MZBC origin were examined, and four revealed trisomy 3. Five of 13 non-MZBC lymphomas revealed trisomy 3. None of the chronic gastritis cases nor normal tonsil cases revealed trisomy 3. Our results, using a different methodological approach, confirm the findings of others that trisomy 3 is an abnormality found in a significant proportion of lymphomas of MZBC origin. Our approach also makes possible interphase cytogenetic analysis (by FISH) of routinely processed formalin-fixed, paraffin-embedded tissues, without the need to disaggregate cells. It thus may facilitate genetic analysis on specimens previously deemed unsuitable for such analysis, particularly when tissue quantity is limited. 相似文献

The authors describe a case of Miller-Fisher syndrome in a child who presented to the ophthalmology department with bilateral abducens nerve palsies. Miller-Fisher syndrome is an important differential diagnosis in any case of bilateral sixth nerve palsies but should only be definitively diagnosed once tumors, infections, and other neurological diseases have been conclusively ruled out. 相似文献

Background:
Hip range of motion is an important component in assessing clinical orthopedic conditions of the hip, low back and lower extremities. However it remains unclear as to what constitutes the best tool for clinical measurement. The purpose of this study was to investigate the concurrent validity of passive range of motion (ROM) measurements of hip extension and hip internal and external rotation using a digital inclinometer and goniometer.Design:
Criterion StandardSetting:
Clinical research laboratoryParticipants:
30 healthy subjects without pain, radicular symptoms or history of surgery in the low back or hip regions.Main Outcome Measures:
Passive hip range of motion for extension, hip internal rotation and hip external rotation. A digital inclinometer and universal goniometer were utilized as the tools for comparisons between measurements.Results:
There was a statistically significant difference (p < 0.05) between the goniometer and digital inclinometer in measured hip ROM except for measurements of right hip external rotation (p > 0.05). The mean difference between the goniometer and digital inclinometer in left hip extension, internal rotation and external rotation were 3.5°, 4.5° and 5.0° respectively. The mean difference between the two devices in right hip extension, internal rotation and external rotation were 2.8°, 4.2° and 2.6° respectively. On average, the difference between the goniometer and digital inclinometer in extension was 3.2°, internal rotation was 4.5° and external rotation was 3.8°. The digital inclinometer had greater measurement during EXT and ER. Furthermore, there was no statistically significant difference (p > 0.05) in hip ROM between the left and right side for either goniometric or digital inclinometer measurements.Conclusions:
This results of this study indicate that a significant difference exists between the two devices in all measurements with exception of right hip extension. The differences were noted to be between 3–5 degrees for all planes measured. These findings suggest that caution should be used if these two devices are to be used interchangeably to quantify passive hip range of motion in either clinical practice or when comparing studies that utilize different instruments.Level of Evidence:

Accurate diagnosis of glucose-6-phosphate dehydrogenase (G6PD) deficiency is required to avoid the risk of acute hemolysis associated with 8-aminoquinoline treatment. The performance of the BinaxNOW G6PD test compared with the quantitative spectrophotometric analysis of G6PD activity was assessed in 356 Plasmodium vivax-infected subjects in Brazil, Peru, Thailand, and India. In the quantitative assay, the median G6PD activity was 8.81 U/g hemoglobin (range = 0.05–20.19), with 11 (3%) subjects identified as deficient. Sensitivity of the BinaxNOW G6PD to detect deficient subjects was 54.5% (6 of 11), and specificity was 100% (345 of 345). Room temperatures inadvertently falling outside the range required to perform the rapid test (18–25°C) together with subtlety of color change and insufficient training could partially explain the low sensitivity found. Ensuring safe use of 8-aminoquinolines depends on additional development of simple, highly sensitive G6PD deficiency diagnostic tests suitable for routine use in malaria-endemic areas. 相似文献

Background:
Patellofemoral pain is a common condition without a clear mechanism for its presentation. Recently significant focus has been placed on the hip and its potential role in patellofemoral pain (PFP). The majority of the research has examined hip strength and neuromuscular control. Less attention has been given to hip mobility and its potential role in subjects with PFP.Purpose/Aim:
The purpose of this study was to compare passive hip range of motion (ROM) of hip extension and hip internal and external rotation in subjects with PFP and healthy control subjects. The hypothesis was that subjects with PFP would present with less total hip ROM and greater asymmetry than controls.Design:
Two groups, case controlled.Setting:
Clinical research laboratoryParticipants:
30 healthy subjects without pain, radicular symptoms or history of surgery in the low back or lower extremity joints and 30 subjects with a diagnosis of PFP.Main Outcome Measures:
Passive hip extension, hip internal rotation (IR) and hip external rotation (ER). A digital inclinometer was used for measurements.Results:
There was a statistically significant difference (p<0.001) in hip passive extension between the control group and the PFP group bilaterally. Mean hip extension for the control group was 6.8° bilaterally. For the PFP group, the mean hip extension was −4.0° on the left and −4.3° on the right. This corresponds to a difference of means between groups of 10.8° on the left and 11.1° on the right with a standard error of 2.1°. There was no statistically significant difference (p>0.05) in either hip IR or ER ROM or total rotation between or within groups.Conclusions:
The results of this study indicate that a significant difference in hip extension exists in subjects with PFP compared to controls. These findings suggest that passive hip extension is a variable that should be included within the clinical examination of people with PFP. It may be valuable to consider hip mobility restrictions and their potential impact on assessment of strength and planned intervention in subjects with PFP.Level of Evidence:
