This paper reports late effects and health status of 198 children who had cancer or leukemia diagnosed under 2 years of age and their therapies electively withdrawn. This series (92 neuroblastoma [NBL], 57 Wilms' tumor [WT], 46 acute lymphoblastic leukemia [ALL], and 3 non-Hodgkin's lymphoma) was followed for 1-12 years after discontinuation of therapy. Thirty-three children were diagnosed before 1973, 92 between 1973 and 1977, and 73 after 1977 in 16 Italian Pediatric Oncology Centers. As of December 1983, 176 children were reported to be alive and without evidence of primary cancer by physicians responsible for their care. One child died from a second primary tumor, two from late recurrences of the primary cancer, and three from other causes; eight were alive with evidence of primary cancer; and eight were lost to follow-up. Kyphoscoliosis was found in 22 children and other musculoskeletal anomalies in 8. Neurological sequelae were observed in 8 out 35 children with ALL treated with radiotherapy (RT) and intrathecal methotrexate. All but one were in continuous complete remission when they developed seizures (three cases), leukoencephalopathy (three cases), or intracerebral calcifications (two cases). One child had cardiomyopathy and subsequently died from cardiac failure: he had received doxorubicin (400 mg/m2) and mediastinal RT (13 Gy) for NBL. Growth impairments were observed in children with NBL and WT.

Computed tomography and magnetic resonance imaging in the elderly have demonstrated the common occurrence of deep white-matter lesions in the aging brain. These radiologic lesions (leukoaraiosis) may represent an early marker of dementia. At autopsy, an ischemic periventricular leukoencephalopathy (Binswanger's disease) has been found in most cases. The clinical spectrum of Binswanger's disease appears to range from asymptomatic radiologic lesions to dementia with focal deficits, frontal signs, pseudobulbar palsy, gait difficulties, and urinary incontinence. The name senile dementia of the Binswanger type (SDBT) is proposed for this poorly recognized, vascular form of subcortical dementia. The SDBT probably results from cortical disconnection most likely caused by hypoperfusion. In contrast, multi-infarct dementia is correlated with multiple large and small strokes that cause a loss of over 50 to 100 mL of brain volume. The periventricular white matter is a watershed area irrigated by long, penetrating medullary arteries. Risk factors for SDBT are small-artery diseases, such as hypertension and amyloid angiopathy, impaired autoregulation of cerebral blood flow in the elderly, and periventricular hypoperfusion due to cardiac failure, arrhythmias, and hypotension. The SDBT may be a potentially preventable and treatable form of dementia.

Here we report the clinical and pathological findings in a 30-year-old drug addict in whom an intravenous injection of heroin led to reversible coma with respiratory depression and heart failure. On regaining consciousness, the patient was found to have rhabdomyolysis with renal failure requiring dialysis and peripheral neuropathy. Three weeks later his neurological condition suddenly deteriorated and delayed encephalopathy developed, leading to death 20 days later. The neuropathological study of the brain disclosed pale, spongy myelin with diffuse reactive astrogliosis and microglial proliferation, without hypoxic necrotic lesions. The cerebral and cerebellar cortices were unchanged. The absence of typical hypoxic lesions and the presence of spongiosis with massive astrocytosis distinguished this case from the previously reported cases of delayed leukoencephalopathy following severe hypoxia. An immunocytochemical study designed to exclude an underlying alteration of the metabolic oxidative pathway detected normal expression of the respiratory chain complexes IV, III and V. Despite the absence of an oxidative chain alteration in our patient, we cannot exclude the possibility that an individual predisposition played a pathogenetic role in this delayed leukoencephalopathy.

The emergence of heart transplantation as the ultimate treatment for end-stage heart failure has been accompanied by new diagnostic challenges. Computed tomography (CT) has emerged as an important diagnostic tool in the evaluation of heart transplant recipients because many infectious, ischemic-hemorrhagic, and neoplastic complications are amenable to early detection with this modality. In the early postoperative period, CT is mostly indicated in the evaluation of infectious complications or cerebral symptoms. Later, CT is mostly performed for staging of infectious or neoplastic disease. Infectious complications include mediastinitis, soft-tissue inflammation, abscess formation, cerebral infarction, and aspergillosis. Complications related to ischemia or hemorrhage include allograft rejection and coronary allograft vasculopathy, the latter being the leading long-term cause of death in heart transplant recipients. CT is also indicated in malignant disease (eg, lymphoma, visceral carcinoma, skin tumors), which is the second most important long-term cause of death. Moreover, CT is helpful in identifying disease caused by immunosuppressive therapy (eg, leukoencephalopathy, osteoporosis, thoracic lipomatosis). CT has proved superior to both ultrasound and magnetic resonance imaging in the evaluation of heart transplant recipients. It has become the diagnostic modality of choice for many transplant-related complications and may help improve postoperative treatment of affected patients.

We report two cases of malignant hypertension with reversible diffuse leukoencephalopathy demonstrating a nocturnal blood pressure (BP) rising pattern ("riser" pattern). Case 1 was a 54-year-old man diagnosed with malignant hypertension who presented with diffuse leukoencephalopathy and nocturnal BP rise during the acute phase. These abnormal findings diminished after treatment of hypertension. Case 2 was a 50-year-old woman diagnosed with malignant hypertension in association with leukoencephalopathy, heart failure and acute renal failure. She also presented with a "riser" pattern during the acute phase. In contrast to case 1, the leukoencephalopathy and "riser" pattern in case 2 were not improved even after 1 month of treatment. Following intensive antihypertensive treatment, renal failure was improved in case 1, but renal failure was not improved after 1 month in case 2. In conclusion, a possible explanation of this phenomenon is that a causative volume overload due to renal dysfunction produced the temporal leukoencephalopathy-like brain edema and "riser" pattern in these cases.

The pathogenesis of dementia associated with Fabry disease was examined neuropathologically in an autopsy case. The patient was a 47-year-old computer programmer who developed renal failure at the age of 36, necessitating peritoneal dialysis, and thereafter suffered in succession episodic pulmonary congestion, bradyacusia, heart failure, and dementia, before dying of acute myocardial infarction. MRI of the brain demonstrated leuko-araiosis. The CNS parenchyma showed widespread segmental hydropic swelling of axons in the bilateral cerebral and cerebellar deep white matter in addition to neuronal ballooning due to glycolipid storage in a few restricted nuclei and multiple tiny lacunae. Hydropic axonal swelling was also sparsely distributed in the pyramidal tract, pedunculus cerebellaris superior and brachium colliculi inferioris, but wallerian degeneration of these tracts was absent. Additional features included angiopathy of the subarachnoidal arteries due to Fabry disease, such as medial thickening resulting from glycolipid deposition in smooth muscle cells (SMCs) and adventitial fibrosis with lymphocytic infiltration, together with widespread subtotal or total replacement of medial SMCs by fibrosis, associated with prominent intimal fibrous thickening and undulation of the internal elastic membrane of medium-sized (1000-100 microm diameter) arteries. The findings in this case suggest that axonopathic leukoencephalopathy due to multisegmental hydropic swelling of axons in the bilateral cerebral deep white matter is responsible for the dementia associated with Fabry disease, and may be caused by ischemia resulting from widespread narrowing and stiffening of medium-sized subarachnoidal arteries and progressive heart failure.

Non-syndromic, multi-organ mitochondrial disorders (MIDs) are frequently missed if treating physicians are not aware of them. We report a 85 years old Caucasian male, referred for tonic-clonic seizures, presenting with a plethora of abnormalities, including neurodermitis, atopic dermatitis, diabetes, hypertension, renal insufficiency, non-specific colitis, urine bladder lithiasis, bilateral cataracts, atrial fibrillation, diverticulosis, polyneuropathy, vitamin-D-deficiency, renal cysts, left anterior hemi-block, right bundle branch block, pulmonary artery hypertension, and heart failure. Neurological investigations revealed ptosis, quadriparesis, fasciculations, dysarthria, dysdiadochokinesia, tremor, hyperkinesia, ataxia, leukoencephalopathy, and basal ganglia calcification. Based upon this combination of abnormalities a non-syndromic mitochondrial multi-organ disorder syndrome (MIMODS, encephalo-myo-cardiomyopathy) was diagnosed.

Multiple organ dysfunction syndrome (MODS) has rarely been described in patients with heroin intoxication. Here, we report a rare case of MODS involving six organs, due to heroin intoxication. The patient was a 32-year-old Chinese man with severe heroin intoxication complicated by acute pulmonary edema and respiratory insufficiency, shock, myocardial damage and cardiac insufficiency, rhabdomyolysis and acute renal insufficiency, acute liver injury and hepatic insufficiency, toxic leukoencephalopathy, and hypoglycemia. He managed to survive and was discharged after 10 weeks of intensive care. The possible pathogenesis and therapeutic measures of MODS induced by heroin intoxication and some suggestions for preventing and treating severe complications of heroin intoxication, based on clinical evidence and the pertinent literature, are discussed in this report.

Cheyne-Stokes respiration (CSR) is a form of sleep-disordered breathing characterised by recurrent central sleep apnoea alternating with a crescendo-decrescendo pattern of tidal volume, relatively rare observation in sleep labs. It is mainly seen in severe heart failure and stroke. We report the case of a young man with CSR after sudden onset of seizure in the context of hypertensive exacerbation leading to the diagnosis of a leukoencephalopathy, and comment on differential diagnoses, prognostic and therapeutic outcomes. The very uniqueness of this case consists in the extremely young age for developing a vascular encephalopathy in the absence of genetic diseases and without previous diagnosis of hypertension. There is no adequate explanation for the origin of vascular encephalopathy; also there is lack of evidence regarding the benefits and modality of treatment for CSR in neurologic diseases. Thus, we were forced to find the best compromise in a nocturnal oxygen therapy and follow-up.
