Out of 334 children with acute lymphoblastic leukemia who were treated with St Jude Total XI and Total XIII chemotherapy protocols were investigated and 21 (6.3%) were hypertensive. The incidence of tumor lysis syndrome was higher in the hypertensive group than in the nonhypertensive group (28.6% vs. 11.5%) (P = 0.035). There were no differences between… (More)
In a patient with fat embolism to the brain CT showed no abnormality. MRI performed after recovery from coma, when the patient had aphasia and quadriparesis, demonstrated multiple high signal abnormalities in the white matter on both T1- and T2-weighted images. HMPAO-SPECT showed left-sided hypoperfusion which resolved in parallel with clinical improvement… (More)
The aim of this study was to determine the effects of pentoxifylline (Ptx) in reperfusion injury of the small bowel as a leukocyte stabilizer, free radical scavenger, and microcirculatory regulator. Ninety-six male Sprague-Dawley rats were used to determine the biochemical, histopathologic and blood flow changes of the reperfused small intestines after 30… (More)
UNLABELLED Dobutamine is a positive inotropic and chronotropic agent and is being widely used as a pharmacologic stress agent in patients unable to achieve maximal dynamic exercise test. The purpose of the current study was to document the dobutamine induced false-positive septal defect in terms of its frequency and extent on 201Tl myocardial SPECT in… (More)
Radionuclide scanning with tumour-seeking agents such as pentavalent technetium-99m dimercaptosuccinic acid [99mTc(V)-DMSA], thallium-201 and technetium-99m sestamibi (MIBI) has been reported to be useful in the detection of medullary thyroid carcinoma (MTC). We undertook a study in 14 MTC patients to determine the comparative imaging potential of 201Tl,… (More)
Scintigraphy using hexakis (2-methoxyisobutylisonitrile) technetium (I) [Tc-MIBI] was performed in a patient with osteosarcoma of the right tibia. Increased accumulation of Tc-MIBI was observed in the primary site of the tumor as well as in metastatic lesion of the right inguinal lymph nodes, which were later confirmed by biopsy.
Thirty-three patients fulfilling the clinical criteria for brain death were tested by Brainstem Auditory Evoked Potentials (BAEP) and Radionuclide Cerebral Angiography and Brain Perfusion Studies. There was a significant correlation between the BAEP and radionuclide study outcomes. All patients with absence of BAEP showed no cerebral perfusion. These… (More)
Myocutaneous flaps are used widely in the surgical treatment of advanced cancers, which in the past had been thought to be inoperable. Tumor recurrences are expected more frequently in these patients. Recurrent tumors may spread locally and to the regional areas via lymphatics and vessels. However, the lymphatic spread may differ in cases where myocutaneous… (More)
The Asperger syndrome, a less severe variant of autism, has drawn increasing interest among child psychiatrists. Cerebral blood flow studies with autistic subjects have failed to reveal consistent findings. We are reporting a case with the Asperger syndrome, whose single photon emission computed tomography showed left occipital hypoperfusion.
UNLABELLED With decreasing incidence of pneumocystis carinii pneumonia (PCP) in AIDS as a result of prophylactic regimens, there is a higher incidence of tuberculosis (TB), mycobacterium avii complex (MAC), kaposi sarcoma and malignant lymphoma. There is a need for differentiating these various pathological entities. The purpose of this study was for a… (More)
