We report the case of a 7 month-old girl that presented with acute anemia, generalized muscular hypotonia and failure to thrive. Laboratory evaluation revealed cobalamin deficiency, due to a vegan diet of the mother. The clinical triad of an acquired floppy baby syndrome with megaloblastic anemia and failure to thrive is pathognomic for infantile cobalamin deficiency. Neurological abnormalities are often irreversible and may be associated with delayed myelinization in the MRI. A normal cobalamin level in maternal serum and absence of anemia do not exclude subclinical deficiency. If cobalamin deficiency is suspected, e.g. in pregnant women on vegan diet, urinary methylmalonic acid excretion and plasma homocysteine levels should be determined and cobalamin substitution should be started at an early stage to avoid potentially irreversible damage of the fetus.

A 70-year-old female was admitted to our hospital with high fever about 5 days before this writing, along with anemia and hyperglycemia. Upper gastrointestinal series and endoscopy revealed type 1 gastric cancer in the greater curvature. CT and MRI showed multiple liver metastasis in the right lobe. Distal partial gastrectomy with lymphadenectomy and cannulation of hepatic artery was performed. The pathological findings revealed moderately-differentiated adenocarcinoma, T2, N0, H1, M0, stage IV. The postoperative chemotherapy with S-1 (80 mg/day) was administered for 4 weeks followed by 1 week rest and CDDP (50 mg) administered once every 4 weeks by arterial infusion. Two months after operation the tumor marker values have become normal, and CT can hardly detect the metastatic liver tumors. At 8 months after operation, CT and MRI revealed complete disappearance of these tumors. Then, 12 months after operation, FDG-PET revealed no accumulation. Now, at 18 months, the CR stage has been maintained. Combined use of peroral S-1 and CDDP by arterial infusion is effective for multiple liver metastasis after gastrectomy in gastric cancer.

Burkitt's lymphoma is a rare disease that belongs to the aggressive non-Hodgkin's lymphoma. Herein, we report a case of primary hepatic Burkitt's lymphoma. A 19-year-old man visited the hospital for right upper quadrant pain. He felt fatigue for two months. Physical examination revealed hepatomegaly and no palpable lymph node. He had no fever, weight loss, or night sweating. Laboratory finding showed mild anemia (hemoglobin, 12.4 g/dL), mild elevated transaminase (ALT, 52 IU/L), elevated lactate dehydrogenase (LDH, 437 IU/L), and alkaline phosphatase (ALP, 129 IU/L). The viral marker was positive for HBsAg, HBeAg, anti-HBs, and anti-HBc (IgG), and negative for anti-HBe, anti-HCV, and anti-HIV. CEA, AFP, and CA19-9 levels were within normal ranges. The HBV DNA quantitation was 1.3 x 10(9) copies/ml. Abdominal-Pelvis CT scan and abdominal MRI finding were compatible with malignant lymphoma. Liver biopsy examination confirmed Burkitt's lymphoma. No metastasis was detected in the thoracic cavity, bone marrow, and spinal fluid. The patient was treated with the combination regimen of cyclophosphamide, doxorubicin, vincristine, prednisone and high dose methotrexate. Cytosine arabinoside and methotrexate were added for CNS prophylaxis by intrathecal installation. Chemotherapy was administered every 3 weeks for fifteen cycles. Serial follow-up CT scan showed a marked decrease in the size of hepatic lesions. Follow-up CT scan and PET-CT scan were performed 4 weeks after the final cycle disclosed no definite residual or active lesion confirming the state of complete remission.

Renal parenchymal hypoxia, documented under a variety of clinical conditions, conceivably contributes to the progression chronic kidney disease. In this review, normal physiologic medullary hypoxia and abnormal profiles of renal pO(2) in chronic kidney diseases are presented, and the mechanisms leading to anomalous renal tissue oxygenation are discussed. Direct measurements of pO(2) with oxygen electrodes, immunostaining with pimonidazole (which binds to regions with very low pO(2)), or the detection of hypoxia-inducible factor (HIF)-alpha (which accumulates in hypoxic regions, initiating hypoxia-adaptive responses), all serve to detect the distribution and extent of renal parenchymal hypoxia under experimental settings. The use of BOLD MRI as a noninvasive tool, detecting deoxygenated hemoglobin in hypoxic renal tissues, has evolved from experimental settings to human studies. All these modalities indicate that abnormal renal oxygenation develops under conditions such as chronic glomerular, tubulointerstitial or renovascular disease, in diabetes, hypertension, aging, renal hypertrophy, anemia or obstructive uropathy. Abnormal renal tissue hypoxia modifies the pattern of regional gene expression, evoking a host of adaptive and renoprotective pathways (such as HIF-mediated erythropoietin or heme-oxygenase-1), in parallel with the induction of potentially harmful mediators that participate in the progression of chronic kidney injury. Slowing the progression of chronic kidney disease may be achieved by a better understanding of these parallel processes and the accomplishment of a selective control of such protective and maladaptive responses.

Delayed post-anoxic encephalopathy has rarely been reported, and has most commonly been associated with carbon monoxide poisoning. The underlying pathophysiological mechanism is unknown. We describe a patient with a delayed neurologic decline after a good initial recovery from a hypoxic-ischemic event precipitated by acute blood loss. MRI revealed early globus pallidus necrosis followed by delayed substantia nigra damage and leukoencephalopathy. We suggest that anemia might play a role in this pattern of hypoxic-ischemic brain injury.

This retrospective study assessed the long-term effect of transfusional exchange therapy on MRA/MRI abnormalities in 24 homozygous sickle-cell anemia (HbSS) children presenting with abnormal brain MRA. The median time elapsed from baseline to last available MRA was 29 months. Follow-up MRAs showed improvement, stabilization or worsening of cerebrovascular lesions in 11, 6 and 7 patients respectively. Complete normalization of MRA was observed in 6 patients within a mean time of 1.4 years, but stenosis recurred at the same location in the 4 patients in whom transfusion therapy was discontinued. Baseline severe stenosis/occlusion of large cerebral arteries and occurrence of moyamoya syndrome were significantly associated with an absence of improvement of the cerebral vasculopathy. These data emphasize the heterogeneity of the course of cerebrovasculopathy in SS children receiving chronic transfusion. Further studies are needed to determine whether different therapeutic approaches have to be considered according to these different evolutive patterns in SS children.

We present a case of a 55-year-old male with progressive neurological deficits that appeared dramatically. MRI detected a spinal epidural hematoma at the cervicothoracic junction and blood tests showed leukocytosis, mild anemia, and thrombocytosis. Spontaneous spinal epidural hematoma (SSEH) as the initial presentation of leukemia was diagnosed. Urgent posterior decompression was performed after 28 h from acute onset of backache, and the patient experienced remarkable improvement in neurological findings.

Silent infarcts have been reported most commonly in school-aged children with homozygous sickle cell disease (SCD-SS) and are associated with neurocognitive deficits. However, the prevalence of silent infarcts in younger children with SCD-SS is not well defined. In this retrospective study, brain magnetic resonance imaging and angiography (MRI/A) studies performed before 6 years of age in a cohort of children with SCD-SS were analysed and the prevalence of abnormalities was calculated. Clinical and laboratory parameters were compared between the groups with and without silent infarcts. Sixty-eight of 96 children in the cohort had brain MRI/A performed prior to age 6 years. Of the 65 who were neurologically asymptomatic, 18 (27.7%, 95% CI 17.3-40.2%) had silent infarcts (mean age 3.7 +/- 1.1 years, range 1.3-5.9 years). Factors associated with silent infarcts included cerebral vessel stensosis by magnetic resonance angiography, lower rates of vaso-occlusive pain and acute chest syndrome and lower haemoglobin levels. The prevalence of silent infarcts in young children with SCD-SS is similar to that of older children and anaemia and severe vasculopathy may be risk factors.

The treatment of advanced cervix is concomitant radiochemotherapy. Local prognosis and global survival depend on tumoral volume, locoregional extension and radio sensitivity of the lesion. This one is function of tumoral hypoxia, tumoral interstitial pressure and existence of an anaemia. DCE-MRI allows to quantify pilot vascular parameters of the first two factors. Combined analysis: tumoral volume, anaemia and vascular parameters before and in the course of treatment allows a strong correlation with the risk of local recurrence and global survival.

A 66-year-old woman, complaining of anal bleeding with anemia, was examined and diagnosed as advanced rectal cancer. Hemoglobin level at admission was 8.8 g/dL. Abdominal CT and MRI revealed a solid tumor of 43x45 mm in diameter. Colostomy was preceded for the purpose of bleeding control under the blood-augmented treatment on the 7th day of hospitalization. Preoperative chemoradiation was performed (a total of 40 Gy radiation+FOLFOX4 for 1 cycle) and obtained a significant size reduction of the tumor (reduction rate 75%). Abdomino-perineal resection of rectum was performed with 550 mL of hemodilutional autotransfusion 3 months after the initiation of treatment. Pathological findings showed moderately differentiated adenocarcinoma with Stage III a. Vaginal fistula as an irradiation associated with complication was healed by duly performed debridement. The patient has survived for 31 months with no recurrence, which indicates that preceded colostomy and preoperative chemoradiation enabled a curative resection safely for the Jehovah's Witness patient with bleeding advanced rectal cancer.
