Percutaneous ethanol injection therapy in the treatment of thyroid and parathyroid diseases.

Relevant English language articles published from 1966 to 1995 regarding ethanol therapy in the treatment of thyroid and parathyroid diseases were identified through a MEDLINE search and manual searches of identified articles. The sclerosing properties of ethanol have been recognized for many years and have offered interventional possibilities in the management of various benign as well as malignant lesions. The mechanism of action of ethanol appears to be related to a direct coagulative necrosis and local partial or complete small vessel thrombosis. Ultrasound-guided percutaneous ethanol injection therapy (PEIT) is rapid and performed on an out-patient basis and has now gained wide acceptance due to the accumulating evidence of the efficacy and safety of this therapeutic tool. Yet, there is a lack of prospective, randomized clinical trials comparing PEIT with 131I therapy or surgery with regard to its effects, especially long-term ones and it should therefore still be considered an experimental procedure. In benign endocrine diseases, PEIT has shown promising results in the treatment of autonomous thyroid nodules, benign solitary cold solid as well as cystic thyroid nodules and parathyroid tumours. Its use in pretoxic and toxic thyroid nodules has been evaluated in several uncontrolled studies, all demonstrating a high success rate in spite of the large number of treatments needed. So far efficacy and cost-effectiveness seem inferior to 131I and surgery. Short-term results of PEIT in benign cystic thyroid nodules are convincing with a high cure rate, but no controlled studies with long-term results are available. Preliminary results suggest that PEIT could become an alternative to surgical excision or levothyroxine therapy in the symptomatic solid cold benign thyroid nodule. Ultrasound-guided PEIT of parathyroid tumours has proven to be a useful method in highly selected patients in whom surgery has been found non-attractive and medical treatment ineffective. However, no prospective randomized trials have been published comparing the results of PEIT in parathyroid tumours with conventional surgical and medical treatments. PEIT has never been tested against standard therapy, but seems inferior to 131I and surgery. Side-effects caused by ethanol injection are generally few and transient and are related to the injection into solid nodules rather than cysts. Ethanol injection into solid profund nodules may seriously jeopardize subsequent surgery because of perinodular fibrosis. As an experimental procedure, not yet evaluated sufficiently, it should be reserved for patients who cannot or will not undergo standard therapy. Caution in routine use is advisable.

The efficacy of treatment for aphasic persons: a meta-analysis.

A meta-analysis of research findings is reported on the effectiveness of treatments for persons suffering aphasia. Twenty-one studies provided sufficient information for inclusion in the analysis. The magnitudes of three classes of effect sizes were estimated: untreated recovery, treated recovery, and treated versus untreated recoveries. The outcomes witness the clear superiority in performance of persons receiving treatment by a speech-language pathologist.

Preschool language disorders and subsequent language and academic difficulties.

Sixty-three language-disordered children first evaluated in their preschool years were followed four to five years after initial diagnosis. At follow-up approximately 40% of these children continued to present speech and language problems and approximately 40% presented other learning problems. Preschool levels of language comprehension, formulation, semantics, syntax, phonology, and speech production were found to be moderately correlated to subsequent class placement in the elementary grades. Duration of preschool therapy was not related to either the severity of preschool language disorder or to any subsequent speech, language, or academic abilities. Duration of school therapy was related to severity of phonologic deficit as rated during the preschool years and to all follow-up ratings for speech, language, and academic abilities.

Occupational therapy incorporating animals for children with autism: A pilot investigation.

This investigation compared language use and social interaction in children with autism receiving two forms of occupational therapy: occupational therapy using standard techniques, and occupational therapy incorporating animals. Twenty-two children between the ages of 7 and 13 received both forms of therapy in a school-based occupational therapy program for children with autism. Results suggest that the children demonstrated significantly greater use of language and significantly greater social interaction in sessions incorporating animals when compared to sessions using exclusively standard occupational therapy techniques. Findings are discussed in the context of recent research that has highlighted the importance of enhancing the motivation of children with autism to engage actively in therapeutic and learning processes.

Receptive and expressive language function of children with symptomatic HIV infection and relationship with disease parameters: a longitudinal 24-month follow-up study.

OBJECTIVES: To longitudinally assess the receptive and expressive language functioning of children with symptomatic HIV disease and to explore the relationship between immune status, computed tomography (CT) brain scan abnormalities, and language dysfunction over time. METHODS: Children with symptomatic HIV infection were administered an age-appropriate standardized comprehensive language test and general cognitive measure prior to starting antiretroviral therapy (n = 44) and again after 6 months (n = 29) and 24 months (n = 17). CD4 percentage and CT brain scans were also obtained at each evaluation. RESULTS: Expressive language was significantly more impaired than receptive language at the baseline, 6- and 24-month evaluations. No significant changes over time were found in receptive or expressive language from baseline to after 6 months of antiretroviral therapy, but despite treatment, language scores declined significantly between 6 and 24 months. Overall cognitive function, however, remained stable from baseline to 24 months. Age-adjusted CD4 percentage increased significantly over the initial 6 months, then remained stable. Overall CT brain scan severity ratings did not change significantly over 24 months. CONCLUSION: Expressive language was consistently more impaired than receptive language over 24 months, further supporting an earlier finding that expressive language was differentially affected by HIV in children with symptomatic disease. Both receptive and expressive language declined significantly after 24 months despite antiretroviral therapy, although overall cognitive function remained stable. Thus, functioning in some domains may be more vulnerable to the effects of HIV and global measures of cognitive ability may mask such differential changes in specific brain functions.

Workplace in fluency management: factoring the workplace into fluency management.

This article addresses competency-based standards and guidelines for the involvement of speech-language pathologists in the workplace of clients who stutter. It advocates broadening customary practices in stuttering treatment and suggests that speech-language pathologists should extend their scope of service delivery to the workplace. It presents a sequence for the collaborative involvement of the employer and other workplace members and proposes strategies for evaluating workplace based fluency programs. Issues of fluency management, transfer, maintenance, and efficacy are discussed in the workplace context. Also addressed is workplace communication as well as such factors as stereotypes, discrimination, and resistance to change which may impinge on workplace intervention. It is argued that structured intervention, transfer, and generalization within a collaborative workplace framework facilitates best practice for the fluency clinician and more appropriate outcomes for the diversity of clients who stutter.

47,XXX: what is the prognosis?

Eleven unselected 47,XXX girls, now 15 to 22 years of age, have been observed from birth in a prospective study of children with sex chromosome anomalies. A description of their growth and development is presented. The 47,XXX infants were not generally distinguishable from chromosomally normal children in the first year of life, even though there was a slight delay in neuromotor development. By 2 years of age, developmental delays in speech and language often became evident, and speech therapy was often necessitated in the preschool years. Early school problems included speech and language deficiencies, lack of coordination, poor academic performance, and immature behavior; these persisted throughout the school years. By high school age, a 47,XXX girl was generally tall and often subject to somatic complaints. Sexual development was generally normal. Seven of the 11 propositae had a diagnosed psychiatric disorder or disturbance at some time during adolescence. Variability within this syndrome is great; one proposita is in college and another is mentally retarded. The frequency of the diagnosis of the 47,XXX karyotype by genetic amniocentesis is estimated to be 1/1000, the same incidence as in the newborn population. Expectant parents must be counseled as to the significance of this karyotype and prognostic information must be given. Suggested guidelines are included.

Setting up a decision support system with decision tables.

The aim of our study was to develop a decision support system using a conventional method which can be used as a shell for different applications. So it was necessary to find a method which allows separation of decision principles and decision algorithms. In addition, documentation of the patient records should be simplified. This could be attained by using the decision table technique and the programming language MUMPS. The general system developed was applied to the therapy decision for patients with liver metastases. The application system was clinically evaluated in a randomized group of patients. In 84% of the study group the therapy proposal of the system concurred with the therapy actually applied. Representation of knowledge in the form of tables is easily understandable by physicians. Since decision tables can be seen as a medium of communication between physician and system manager, knowledge acquisition is simplified.

Thyroxine suppressive therapy in patients with nodular thyroid disease.

PURPOSE: To review evidence about thyroxine suppressive therapy in patients with thyroid nodules, including the clinical importance and natural history of nodules and the effects and potential side effects of thyroxine therapy. DATA SOURCES: English-language articles published from 1986 to December 1996 were identified through searches of the MEDLINE database, selected bibliographies, and personal files. DATA EXTRACTION: Randomized, controlled trials and nonrandomized trials of thyroxine suppressive therapy for solitary and predominantly solid thyroid nodules were reviewed. In most studies, nodule cytology was evaluated by fine-needle aspiration biopsy. Therapy was considered suppressive if suppression was documented by thyroid-stimulating hormone-releasing hormone tests or sensitive thyroid-stimulating hormone assays. Response was defined as a decrease of 50% or more in nodule size or volume; most recent studies measured nodule size by ultrasonography. DATA SYNTHESIS: The evidence suggests that thyroxine suppressive therapy fails to shrink most nodules: Only 10% to 20% of nodules responded to this treatment. Fine-needle aspiration biopsy is more reliable in distinguishing benign from malignant nodules. Recent studies suggest that spontaneous decrease in size with complete disappearance of thyroid nodules is not uncommon. No data show that thyroxine therapy arrests further growth in most existing nodules or prevents the emergence of new nodules. Postoperative thyroxine therapy does not seem to prevent recurrence of thyroid nodules except in patients with a history of radiation therapy. Potential adverse effects of long-term suppressive therapy include osteoporosis and heart disease. CONCLUSIONS: Patients with cytologically benign nodules are best followed without thyroxine treatment. Most benign nodules remain stable in size and remain benign when monitored for a long time. For nodules that increase in size, biopsy should be done again or surgery should be performed.

The acquisition of language skills by autistic children: can parents do the job?

The mothers and fathers of 11 preschool autistic children were taught operant procedures used in teaching speech to nonverbal children. The children's speech skills were assessed twice before and once after their parents were trained. At posttreatment, the children showed significant gains in prespeech and speech skills as measured by a 21-step hierarchy of speech behaviors. Those children who had acquired at least verbal imitative skill after training made greater progress than those who had not. Although children maintained their gains in a 1-year follow-up assessment, there was no evidence of significant improvement beyond that achieved at the end of training. The importance of support for parents in continuing to do formal "teaching" after the training program ends was stressed.
