Clinical care of patients with amyotrophic lateral sclerosis

Although amyotrophic lateral sclerosis and its variants are readily recognised by neurologists, about 10% of patients are misdiagnosed, and delays in diagnosis are common. Prompt diagnosis, sensitive communication of the diagnosis, the involvement of the patient and their family, and a positive care plan are prerequisites for good clinical management. A multidisciplinary, palliative approach can prolong survival and maintain quality of life. Treatment with riluzole improves survival but has a marginal effect on the rate of functional deterioration, whereas non-invasive ventilation prolongs survival and improves or maintains quality of life. In this Review, we discuss the diagnosis, management, and how to cope with impaired function and end of life on the basis of our experience, the opinions of experts, existing guidelines, and clinical trials. We highlight the need for research on the effectiveness of gastrostomy, access to non-invasive ventilation and palliative care, communication between the care team, the patient and his or her family, and recognition of the clinical and social effects of cognitive impairment. We recommend that the plethora of evidence-based guidelines should be compiled into an internationally agreed guideline of best practice.     

Approach to vasculitic neuropathies

Since vasculitic neuropathy is treatable and potentially debilitating, clinicians should develop an approach to neuropathy that increases the likelihood of uncovering existing systemic or nonsystemic vasculitis. The presence of a connective tissue disease, systemic vasculitis, asymmetric or non--length-dependent axonal polyneuropathy, or multiple axonal mononeuropathies should heighten suspicion, but vasculitic neuropathy can also present as a distal symmetric polyneuropathy with or without other organ involvement. Electrodiagnostic testing utilizing extensive nerve conductions may be helpful in identifying features suggestive of vasculitic neuropathy and in selecting an abnormal nerve and muscle for biopsy confirmation. An array of laboratory tests may lead to identification of a systemic disorder that is either characterized by or predisposes to vasculitic neuropathy. The mainstays of treatment are corticosteroids and cyclophosphamide, but other drugs are used in specific conditions. With early diagnosis and careful monitoring of treatment regimens, the prognosis is usually good.     

Parents of children with enduring epilepsy: predictors of parenting stress and parenting

OBJECTIVE: The goals of the work described here were (1) to predict parenting stress and parenting from stressors, resources, and parental coping behaviors in parents of children with epilepsy, and (2) to determine whether parenting stress mediates the effects of these predictors on parenting. METHODS: Participants were 91 parents of children with epilepsy (mean age of children=8 years, 5 months). Parental perceptions of stressors, resources, parental coping behaviors, parenting stress, and parenting were assessed by means of questionnaires. Regression analyses were used to analyze the unique and combined power of the predictors to predict parenting stress and parenting. Sobel tests were used to identify the mediational role of parenting stress. RESULTS: Evidence was found for direct effects of stressors, resources, and coping behaviors on parenting stress and parenting, with relatively large effects for stressors. The mediational role of parenting stress was largest in the domain of parental behavioral control. CONCLUSIONS: In the context of pediatric epilepsy, parenting stress mediates both disruptive and resilient family factors for their effects on parenting. Parents of children with epilepsy may benefit from parent training programs that, to reduce parenting stress, address epilepsy education, the management of difficult child temperament, building social support networks, and the modification of inadequate parental coping behaviors.     

Psychotic symptoms in combat-related post-traumatic stress disorder

The presence of psychotic symptoms in post-traumatic stress disorder (PTSD) has already been recognized. Using the Structured Clinical Interview Diagnostic and Statistical Manual, we searched for and assessed psychotic symptoms in 91 males suffering from combat-related PTSD. Hallucinations and delusions were present in 20% of patients. We divided all patients into three groups: the group with hallucinations and delusions, the group without these symptoms, and the group with "subthreshold" psychotic symptoms. Using the Harvard Trauma Questionnaire, Clinician-Administered PTSD Scale, and Structured Clinical Interview Diagnostic and Statistical Manual, we investigated differences between groups in the intensity of traumatization, severity of PTSD symptoms, and the frequency of depression. There were no significant differences between groups; however, there was one exception: severity of hyperarousal symptoms was positively correlated with occurrence of psychotic symptoms.     

Significance of confirming Epstein-Barr virus nuclear antibody as tumor marker

BACKGROUNND/AIM: Study of the association between Epstein-Barr virus (EBV) and the tumors of the nasopharynx renders an opportunity to introduce causal treatment Already have been proven the anti-EBV (anti-Epstein-Barr nucleus antigene) antibodies in the blood serum of the patients infected with EBV, while over 91% of the patients with nasopharyngeal malignant tumors also have a detectable anti-EBV marker. The aim of this research was to determine if there were anti-EBV antibodies in the serum of the patients with the already verified nasopharyngeal malignant tumors, and, if there were, to determine the quantitative ratio to the values in the serum of the healthy controls. METHODS: The study involved 74 individuals in the period from 1994-2001 divided into four groups: group A counting 11 patients with undifferentiated carcinome of nasopharyngeal type (UCNT); group B counting 25 patients with UCNT X-ray treated at least three years before the onset of the study; group C including 28 healthy subjecets (blood donors), and the group D with 10 patients with planocellular nasopharyngeal carcinoma. Serologic diagnostics of the patients serum was performed using the techniques of Reedman and Klein for the detection of anti-EBV antibodies in the serum. RESULTS: The presence of the statistically significantly higher values of the mean geometric titer (MGT) of the anti-EBNA antibodies was determined in 36 patients with histologically verified UCNT as compared with the control groups including 10 patients with planocellular carcinomas of the nasopharynx and 28 blood donors. Presented were anti-EBNA titers with 95% confidence interval for any participants according to the Hoo clinical classification of nasopharyngeal tumors, as well as according to the fact if they had been radiotreated within the previous three years. CONCLUSION: The results of this study confirm the conclusions of the recent literature on the possible etiopathogenesis of nasopharyngeal tumors and the use of viral anti-EBNA antibodies as viral markers in the diagnostics of UCNT diseases.     

Significance of Helicobacter pylori infection and nonsteroidal anti-inflammatory drugs in patients with bleeding from upper part of the gastrointestinal tract

BACKGROUND/AIM: Helicobacter pylori (H. pylori) infection and nonsteroidal anti-inflammatory drugs (NSAIDs) use are considered to be the most important risk factors having influence on the onset of bleeding gastroduodenal lesions. Whether there is an interaction between H. pylori infection and the use of NSAIDs in the development of peptic ulcer disease is still controversial. The aim of the present study was to evaluate the prevalence of NSAIDs use and H. pylori infection in patients presented with bleeding gastroduodenal lesions. METHODS: During the period from January 2003 December 2003 we prospectively obtained data of all the patients (n=106) presented with signs of upper gastrointestinal bleeding. All the patients were admitted to the intensive care unit, with the endoscopy performed within 12 hours after admission. Histologic analysis was used for the detection of H. pylori infection. The NSAIDs and aspirin use data were obtained by anamnesis. RESULTS: The results of our study revealed that the most common sources of upper gastrointestinal bleeding were duodenal (57 patients, 53.77%) and ventricular (36 patients, 33.96%) ulcers. The majority of the examined cases were associated with both H. pylori infection and NSAIDs use. A statistically significant difference among the studied groups of patients was proven. CONCLUSION: The majority of bleeding gastroduodenal lesions were associated with the coexistance of H. pylori infection and NSAIDs use, while their independent influences were statistically less important. Eradication of H. pylori infection in patients using NSAIDs might prevent upper gastrointestinal hemorrhage and reduce peptic ulcer bleeding risk.     

Botulinum toxin type A for the treatment of spasticity in children with cerebral palsy

BACKGROUND/AIM: Cerebral palsy (CP) is the most common physical disability in childhood. Children have problems with motor functions as a result of limbs spasticity, which leads to severe contractures and limbs deformity. There is a growing interest in the therapeutic role of botulinum toxin type A (BTA) in CP. The aim of this study was to examine the effects of BTA on spasticity, active range of motion and functional motor outcomes in children with CP. METHODS: This study included 42 children of both sexes, aged 2-6 years, with spastic CP, divided into two groups: group I (21 child) treated with BTA and physical therapy, and group II (21 child) treated with physical therapy only. The following parameters were analyzed: spasticity; active range of motion of the hip, knee and ankle, and functional motor outcome. These parameters measurements were carried out four times in both groups: before the treatment, three, eight and 16 weeks after the beginning of the treatment. The obtained results were statistically processed and compared. RESULTS: There was no evidence of any significant difference between the groups before the treatment. After eight weeks there was a remarkable difference concerning spasticity reducing on behalf of the group I (group I -- 0.76 +/- 0.51 vs. II group -- 2.17 +/- 0.64; p < 0.0001). There was statistically significant difference concerning active range of motion increasing on behalf of the group I (hip abduction: group I --44.37 +/- 1.13(0) vs. group II -- 32.61 +/- 8.07(0),p < 0,01; knee extension: group I -- 0.77 +/- 1.82(0) vs. II group -- 14.99 +/- 7.61(0), p < 0.01; dorsiflexion of the foot: group I -- 11.50 +/- 6.08(0) vs. group II -- 8.98 +/- 7.85(0), p < 0.01). A statistically significant difference was found after 16 weeks in functional motor outcome as well, on behalf of the group I: functional motor abilities level in the group I was 1.86 vs. 2.71 in the group II, p < 0.05. CONCLUSION: Botulinum toxin type A application leads to an important spasticity decreasing, active range of motion increasing, as well as to functional abilities in children with CP.     

Optimal nutritional status assessment parameters in gastroenterological patients on hospital admission

BACKGROUND/AIM: There are no recommendations for the optimal nutritional status assessment parameters (NSAPs) in the current literature. The aim of this study was to define the optimal NSAPs for nutritional status assessing in gastroenterological patients on hospital admission. METHODS: Nutritional status of 612 gastroenterological patients was evaluated at the admission using 6 NSAPs: unintentional weight loss (WL), body mass index (BMI), triceps skinfold thickness (TSF), mid-upper arm muscle circumference (MAMC), serum albumin concentration (ALB), and lymphocyte counts (LYM). According to their nutritive status, the patients were classified as well nourished (normally nourished and obese), moderately undernourished and severely undernourished. Based on the similarities and differences in the assessment results, obtained according to each of 6 parameters, the optimal nutritional assessment parameters were defined, separately for the well-nourished/undernourished patients and for moderately/severely undernourished patients. RESULTS: The incidence of malnutrition was in the range 5.9-29.7%. The results based on MAMC, ALB, and LYM were similar (25.2-29.7%; p > 0.05), while the results based on WL, BMI, and TSF differed significantly (5.9-19.9%; p = 0.001-0.015). The assessment based on BMI was the most severe criterion, while the assessment according to MAMC was the mildest criterion in selection of malnourished patients. The assessment according to MAMC was the mildest criterion for the selection of severe malnourished patients (severely malnouorished patients accounted for 70.1%), while BMI and LYM were the most severe criteria (severely malnouorished patients accounted for 22.2% and 27.3%, respectively). The results based on BMI and LYM were similar (Wilcoxon test; p > 0.05). CONCLUSION: Combining BMI with MAMC is sufficient for the assessment of the nutritional status of gastroenterological patients on admission, as well as for differentiation between severely malnourished and moderately malnourished patients.
