A summary of clinical data is presented on 34 men and 52 women patients with brain syndrome associated with delayed neuropsychiatric sequelae following acute carbon monoxide intoxication. Their ages ranged from 34 to 82 years, with peak incidence in the sixth and seventh decade. Possible etiological factors were age, duration of unconsciousness on acute intoxication, and previous physical illness. The onset was relatively sudden after the apparent clear period which ranged from 2 to 40 days (mean 22.5 days). The most frequent symptoms were apathy, dull facial expressions, dementia, such as amnesia and disorientation, hypokinesia, mutism, irritable distractibility, urinary and/or fecal incontinence, gait disturbance and abnormal neurological signs and reflexes. EEG was abnormal in 33 of the 57 cases (58%). Of 27 patients who were given a computed tomographic brain scan, 15 patients were abnormal. The prognosis was relatively good in the follow-up study of 56 patients. Only age was related to a better prognosis.

The patient, a 65-year-old woman, had liver cirrhosis, and had blood transfusion at the age of 49 and 56. Early in September, 1989, she gradually developed numbness of the legs, staggering gait, and apathy with hallucination. In October, she became incontinent and unable to stand, and was admitted to Konan Hospital. On admission, she was disoriented with poor comprehension. Cranial nerves were intact except for horizontal nystagmus on lateral gaze. She had generalized areflexia without pathological reflex. Muscular forces were fairly preserved. Superficial sensations were diminished in the upper limbs as well as below Th-7 level. Deep sensation was abolished in the distal parts of the extremities with athetotic finger postures on arm rising. She had urinary and fecal incontinence. Results of routine laboratory examinations were non-contributory. Chest CT scan and sputum cytology were normal. CSF contained one cell/microliter, 95 mg/dl of protein with positive oligoclonal IgG bands. Anti-HTLV-I antibody was positive in serum and CSF. Urodynamic studies showed neurogenic bladder of supranuclear type. MNCV was slightly decreased. SNAP and SEP were not evoked. On sural nerve biopsy, the density of myelinated fibers was 720/mm2, and that of unmyelinated fibers, 26,978/mm2. ABR and VEP were abnormal. EEG showed diffuse theta waves with paroxysmal delta and sharp waves. T2-weighted MR images of the brain showed patchy areas of high signal intensity in the cerebral white matter. Soon after administration of methylprednisolone, her consciousness became clear. EEG normalized in 4 months. Twenty months after the onset, she became ambulant with crutch, but still has dysuria and sensory deficits in the hands and lower limbs. The possible relationship between encephalomyeloneuritis and HTLV-I infection was discussed.

Wound healing is a complex, tightly regulated process, consisting of three distinct phases. In each phase of wound healing, energy and macronutrients are required. Moreover, animal studies have established a specific role for certain nutrients such as the amino acid arginine, the vitamins A, B, and C, and the elements selenium, manganese, zinc, and copper. Chronic wounds such as pressure ulcers have extensively been investigated as to the risk of development, prevention, and cure. Here, the combination of old age, malnutrition, and pressure ulcers is highly unfortunate. Energy and nutrients, such as proteins and vitamins B and C, being deficient at old age are needed in pressure ulcer healing. Malnutrition is associated with skin anergy and with immobility because of mental apathy and muscle wasting. Severe malnutrition, impaired oral intake, and the risk of pressure ulcer formation appear to be interrelated. Adequate nutrition may reverse the underfed state unless an underlying wasting disease was present and appeared to reduce the prevalence and incidence in cross-sectional and prospective observational studies. However, attempts to prevent pressure ulcers by nutritional intervention were divergent in outcome, reflecting the difficulties to meet the daily requirements in elderly persons and the lack of knowledge about true nutritional needs in wound healing. The consumption of a diet high in protein and energy may promote pressure ulcer healing. When considering nutritional support, oral supplementation should be weighted against tube feeding, as the associated morbidity of tube feeding, i.e., diarrhea, fecal incontinence, and restricted mobility being in themselves risk factors for pressure ulcers, might obscure the favorable effects of adequate nutrition. Despite the evidence in animal studies, none of the above-mentioned specific nutrients promoted the healing of pressure ulcers in humans. Therefore, the attention should be focused on early recognition of a depleted nutritional status and an adequate and supervised intake of energy (35 kcal/kg) and protein (1.5 g/kg) with provision of the recommended daily allowances of micronutrients and with correction of the nutrient deficiencies of old age.

Up to 39% of children operated for a posterior fossa tumor develop the cerebellar mutism syndrome. Although they are alert and cooperative, with normal language comprehension, they are unable to speak. In addition, patients may demonstrate apathy, bladder and bowel incontinence and long-term language and cognitive disturbances. This devastating syndrome is at the same time intriguing, because it confirms a role for the cerebellum in language and cognitive functions. Recent investigations have led to new insights regarding the cerebellar mutism syndrome. The commonly accepted hypothesis states that the mutism is caused by a hypofunction of cerebral hemispheres, due to damage to the superior cerebellar peduncle and functional disruption of the cerebello-cerebral circuitry. This article focuses on the evidence for and against this hypothesis and its clinical consequences.

We describe the clinical history of a 49-year old woman, who demonstrated progressive personality changes more than twenty years after radiation of a pituitary adenoma (prolactinoma), with apathy, loss of initiative, memory deficits, postural instability, dysarthria and faecal incontinence. Neuropsychological assessment showed impulsivity, loss of overview, desinhibition, fluctuating deficits of attention, and memory disturbances. MRI-scanning of the brain revealed a cystic lesion along the right ventricle. The clinical picture and the findings of the other investigations are typical for dementia due to radiation encephalopathy. Such a long period between radiation and cognitive deterioration is rare, although it has been described before.
