An autopsy case of Ph1--positive acute lymphoblastic leukemia with disseminated infection of Fusarium solani

A 56-year-old woman with Ph1--Positive acute Lymphoblastic Leukemia was admitted to our hospital for induction chemotherapy in June 1999. The patient was presented with a central scotoma of left eye during treatment course and was given diagnosis of endophthalmitis. Thereafter she also developed skin induration and suffered from serious pneumonia. Amphotericin B administration was started because of high titer of beta-D-glucan, but soon discontinued due to its adverse effect. Blood cultures yielded colonies of fungus and it was identified Fusarium solani. Her general condition deteriorated with progression of pneumonia, and she died of respiratory insufficiency. Autopsy was performed, and its specimen revealed the disseminated infection of Fusarium solani (lung, eye, heart, kidney and skin). We should pay special attention to the fusariosis in Japan also.     

Effects of Ethyl Alcohol Administration to THA Rat Dams During Their Gestation Period on Learning Behavior and on Levels of Monoamines and Metabolites in the Brain of Pups after Birth

Children born from chronic alcoholic mothers have shown behavioral teratogenic effects more frequently than morphological malformations. To investigate the possible mechanisms and evaluate maternal alcohol dosage levels to induce behavioral dysfunctions, we gave pregnant Tokai High Avoider (THA) rats 0, 5,10, and 20% ethanol (EtOH) as drinking water during the gestation period. We evaluated the brain function of pups born of alcohol-administered dams. Sidman avoidance behavior test and the levels of monoamines (nor-adrenalin, dopamine, and serotonin) and metabolites (3,4-dihydroxy-phenyl acetic acid, homovanillic acid, and 5-hydroxyindole acetic acid) in whole brain were examined for neurobehavioral and neurochemical effects. EtOH-exposed THA offsprings showed high pre-and postnatal mortality, growth deficits, and brain weight reductions. Compared with the results of the same conditioning experiment using Wistar rats, the THA rat may have higher susceptibility to the effects of in utero EtOH exposure than Wistar rats. EtOH-exposed THA pups exhibited deficits in avoidance operant learning that were not shown in Wistar rats. We also observed the increased levels of all monoamines that were assumed to be related with the deficit of learning, the decreased levels of 3,4-dihydroxyphenyl acetic acid and homovanillic acid, and the unchanged levels of 5-hydroxyindole acetic acid in pups from dams administered 10 and 20% EtOH. However, contrary alteration of monoamines and their metabolites were shown in pups from 5% EtOH-administered dams.

Determinant factors of the difference between self-reported weight and measured weight among Japanese

Objectives

To assess the difference between self-reported and measured weight values in Japanese men and women and to determine the underlying determinants of the differences between self-reported and measured values.

Methods

The data were collected from 363 general Japanese individuals aged 16–88 years living in Kumamoto prefecture. Participants completed a self-administered questionnaire designed for this study with self-reported weight and height values. Measured weight and height were measured immediately after questionnaire completion. Paired t-tests identified differences between self-reported and measured values by sex. Multiple-stepwise regression analysis examined the independent variables’ effects on the differences between self-reported and measured weights.

Results

Significant differences were found between self-reported and measured values for both sexes (p < 0.001). There was a significant negative relationship between the difference in an individual’s self-reported and measured weight in each sex, with higher measured weight individuals more likely to underestimate their weight. Multiple-stepwise regression analysis models explained 12.1 % (p < 0.01), 11.3 % (p < 0.01), and 5.6 % (p < 0.01) of the variance in all participants, men, and women, respectively. Significant effects were found for age, weight measurement frequency, and measured weight in total participants, weight measurement frequency, and measured weight for men, and age for women.

Conclusions

In this study, the mean absolute value of the weight and height variances proved the unreliability of self-reported weight and height values. This study’s findings suggest self-reported weight inaccuracy especially for obese populations. This should be adjusted when using it in epidemiological studies and healthcare planning.

     

Current status of hybrid intravascular ultrasound and optical coherence tomography catheter for coronary imaging and percutaneous coronary intervention

Both intravascular ultrasound (IVUS) and optical coherence tomography (OCT) play a crucial role in elucidating the pathophysiology of coronary artery disease (CAD) with the goal to improve patient outcomes of medical and/or interventional CAD management. However, no single intravascular imaging technique has been proven to provide complete and detailed evaluation of all CAD lesions due to some limitations. Although sequential use of multiple modalities may sometimes be performed, there may be issues related to risk, time, and cost. To overcome these problems, several hybrids involving dual-probe combined IVUS-OCT catheters have been developed.The aim of this review article is to demonstrate some limitations of stand-alone imaging devices for evaluation of CAD, summarize the advances in hybrid IVUS-OCT imaging devices, discuss the technical challenges, and present the potential value in the clinical setting, especially in patients receiving medical or interventional CAD management.     

Streptococcus oralis Meningitis with Gingival Bleeding in a Patient: A Case Report and Review of the Literature

An 81-year-old man with a history of gingival bleeding presented with a fever, headache, and drowsiness. His mouth and full dentures were unsanitary. Laboratory tests revealed Streptococcus oralis meningitis caused by odontogenic bacteremia. We reviewed eight reported cases, including the present case, because S. oralis meningitis is rare. Our review indicated that S. oralis meningitis needs to be considered when encountering cases of a fever, disturbance of consciousness, and headache with episodes of possible odontogenic bacteremia.     

Acute Myeloid Leukemia Developing with Acute Pancreatitis Mimicking Autoimmune Pancreatitis

A 33-year-old man was admitted to our hospital for fever and abdominal pain. A blood analysis revealed pancytopenia and increased serum pancreatic enzymes with disseminated intravascular coagulation. A detailed examination revealed acute pancreatitis, with diffuse swelling of the pancreas and diffuse beaded dilatation of the main pancreatic duct, which mimicked autoimmune pancreatitis complicated by acute myeloid leukemia. Systemic cytotoxic chemotherapy led to the remission of leukemia and pancreatitis. We hypothesized that the etiology of acute pancreatitis was invasion of leukemia cells. Acute pancreatitis is rare as a symptom of leukemia; however, we should consider the possibility of leukemia during the differential diagnosis of acute pancreatitis.
