Identification of a novel mutation in Cu/Zn superoxide dismutase gene associated with familial amyotrophic lateral sclerosis.

We report a new missense mutation (Ala140Gly) in exon 5 of the Cu/Zn superoxide dismutase (SOD-1) gene in a 73-year-old man with familial amyotrophic lateral sclerosis (FALS). The enzymatic activity of mutated SOD-1 measured in erythrocyte lysate was 70% of control. This heterozygote mutation, which is associated with the late onset of the disease, is located in the active site of the enzyme.

Incidence and predictors of PEG placement in ALS/MND.

In the Project on Death in America ALS cohort, 121 patients were followed to examine the timing of key milestones in the course of the disease, such as tracheostomy and PEG placement. During the 2- to 4-year follow-up period, 26.5% of patients received PEG, yielding a cumulative incidence of 48%. PEG placement occurred, on average, 16 months after patients received confirmation of the diagnosis at our Center. Patients who received PEG were more likely to have tracheostomies than patients not using PEG (p<0.01). In multivariate proportional hazard models that included both sociodemographic and disease indicators, the strongest predictor of PEG use was a patient's baseline preference for PEG: 57.1% of patients "absolutely in favor" went on to have PEG, compared to only 9.3% of those "absolutely against" (p<0.01). PEG users were more likely to have initiated health care proxies. These findings suggest that patients who use PEG may be consistently proactive in the face of the disease.

The ALS Patient Care Database: insights into end-of-life care in ALS.

OBJECTIVE: To study clinical practices and patient outcomes near the end of life in amyotrophic lateral sclerosis (ALS). BACKGROUND: Patients, families, and healthcare providers face several dilemmas in selecting and delivering care near the end of life in ALS. Published data on clinical practices and their benefits during end-of-life care for ALS patients consist of anecdotal reports based on small case series or individual case reports. METHODS: Data were obtained from 1014 American and Canadian patients with ALS who died while participating in a large observational registry (the ALS Patient Care Database) during the past four years. Following death, a caregiver or family member provided data for each patient using a standard questionnaire. Data were principally generated through American and Canadian ALS multidisciplinary centers of excellence. RESULTS: Most patients died peacefully (90.7%) and 62.4% died in a hospice-supported environment. Advance directives were in place for 88.9% of patients and were followed in 96.8%. Among the 67 patients who exhibited distress in the dying process, symptoms included breathing difficulties (82.1%), fear/anxiety (55.2%), pain (23.9%), insomnia (14.9%), and choking (14.93%). Oxygen was given to 52.6% of patients, and pain medications were given to 74%. CONCLUSION: These data suggest that palliative care at the end of life was relatively well managed for most patients with ALS who participated in this study; nevertheless, several opportunities for improvement were identified.

Improving the quality of life for people with ALS: the challenge ahead.

In tandem with recent progress in basic and clinical research in amyotrophic lateral sclerosis (ALS), clinical care and management has improved substantially. Key processes and practices have been established and are specified in current ALS Practice Parameters; the international ALS databases identify the current status of care and management given by physicians. A number of prospective clinical management research studies are now well underway to establish the effective utility of enteral feeding, assistive ventilatory device, and exercise in patients with ALS. One of the main research objectives in the clinical management of ALS is to improve patients' quality of life. For patients with ALS, only comprehensive multidisciplinary care can effectively improve their overall quality of life from diagnosis to death. This paper will briefly review a number of factors that must be considered if we are to improve the quality of life for these patients, including comprehensive medical management, patient education, the importance of hope, the role of the health care professional, and the patients themselves.

Mother with amyotrophic lateral sclerosis and daughter with Creutzfeldt-Jakob disease.

OBJECTIVE: To describe a mother who had autopsy-proved amyotrophic lateral sclerosis and her daughter who had clinically diagnosed Creutzfeldt-Jakob disease. DESIGN: Case reports with molecular genetic analyses. SETTING: A tertiary care center. PATIENTS: The mother had progressive upper and lower motor neuron symptoms and signs starting at the age of 54 years. Electrophysiological testing supported the diagnosis of amyotrophic lateral sclerosis. Autopsy results confirmed the diagnosis. Her daughter had received injections of human growth hormone prepared from pooled human pituitary glands as a child. At the age of 31 years, she experienced the onset of gait ataxia and dysarthria. Cerebrospinal fluid showed the 14-3-3 protein. Cognitive difficulties ensued. She progressed to a nearly akinetic and mute state. She had overt visible fasciculations and muscle atrophy in the legs. MAIN OUTCOME MEASURES AND RESULTS: Neither patient carried a mutation in the prion protein gene. Both were homozygous for methionine at the polymorphic codon 129. Neither patient carried a deletion of the 5 exons of the superoxide dismutase 1 gene. CONCLUSIONS: It is uncertain whether the 2 cases occurred in the same family by chance or whether the patients shared genetic risk factors for the 2 diseases. The possibility that homozygosity at codon 129 is a risk factor for amyotrophic lateral sclerosis is being tested in a case-control study.

Radial forearm fasciocutaneous free flap as a solution in case of Noma.

The authors describe a case of Noma or Cancrum Oris, an oral gangrenous disease, features more frequently found in children from developing countries. The clinical features, its ethiopathogenesis, and its particular link with different geographic and economic areas of the world, its clinical evolution as well as surgical treatment are all discussed. Underlined is the functional and organic aspect of this disease, in particular the distortion of the face, which commonly involves the full thickness of the cheek skin and bone, mandibular ankylosis and craniofacial dismorphisms, and the modern approach in reconstructive microsurgery. The authors report a case of a patient affected by Noma, with a very evident left face dismorphism, where we found a brilliant solution using a left radial forearm fasciocutaneous free flap, appropriately shaped.

Resilience and distress among amyotrophic lateral sclerosis patients and caregivers.

OBJECTIVES: The objectives of this study were to assess the prevalence of depressive disorders and symptoms and their correlates in patients with amyotrophic lateral sclerosis (ALS) and caregiver spouses and to identify dimensions of resilience as well as distress. METHODS: Fifty-six patients with ALS and 31 caregivers were interviewed on one occasion, and 20 patients were subsequently reinterviewed during a scheduled medical visit at an ALS center. Major measures included the Structured Clinical Interview for DSM-IV, the Beck Depression Inventory, the Schedule of Attitudes Toward Hastened Death, quality of life, spirituality, and degree of hopelessness. The ALS Functional Rating Scale, spirometry measures of forced vital capacity, and the Karnofsky Performance Index were used to assess physical status. RESULTS: Neither patients nor caregivers displayed significant psychopathology with respect to either current depressive disorders or scores on symptom scales. Depressive symptoms and psychological distress were not related to time since diagnosis, degree of disability, or illness progression during the period of observation. More interest in hastened death was associated with greater distress, but willingness to consider assisted suicide was not. Among caregivers, perceived caregiver burden was significantly associated with finding positive meaning in caregiving. Concordance between patient and caregiver distress was high, suggesting that attention to the mental health needs of caregivers may alleviate the patient's distress as well. CONCLUSIONS: Clinical depression or significant depressive symptomatology is not an inevitable or common outcome of life-threatening illness, even in the presence of major disability.
