Pharmacologic treatment of tic disorders.

The approach to treating children and adolescents with tic disorders has evolved in recent years such that complete elimination of tics is no longer the primary goal of treatment. Indeed, given the high frequency of psychiatric comorbidity in TS, treatment planning begins with identification of target symptoms. Although traditional neuroleptics still represent standard treatment for tics, many families and clinicians are reluctant to use these agents because of concern about the potential for short- and long-term side effects. Thus, there is great interest in the newer atypical neuroleptics. Interest in the atypical neuroleptics is understandable, but much more study is needed before these agents can become first-line treatments for tics. A small group of non-neuroleptic medications have been used in the treatment of tics. Of these, clonidine, guanfacine, tetrabenazine, pergolide, and botulinum toxin injections have shown some promise for suppressing tics. To date, however, only clonidine has been evaluated in randomized, controlled trials, and the results are not consistent across studies. Although comorbid ADHD is common in children with TS, treatment with stimulant medications was not recommended in children with tics. Recent data suggest that stimulants may be used in some children with TS without adverse effects. Until more is known about which children with ADHD and tic disorders can be safely treated with stimulants, however, the use of stimulants in this population should be undertaken with caution. A handful of nonstimulant medications have been used in the treatment of ADHD with some success, but more study is needed for most of these agents. Evaluation of the stimulants and nonstimulants for the treatment of ADHD in children and adolescents with tic disorders is an area worthy of large controlled trials.

New TMJ clinical data and the implication on diagnosis and treatment.

A review of the literature and the presentation of 220 patients with acute temporomandibular disorders and a control group are presented. Condylar position in the fossae is related to clinical symptoms. Ten important clinical factors were recorded and the data compared without reference to specific condylar position in the fossae and then in relation to condylar displacement groups. The significantly high incidence of posterior condylar displacement and joint pain in the patients described in this report indicates that elimination of the term joint in our definition of this disorder may be premature.

Evaluation of a computer-mediated eating disorder intervention program.

OBJECTIVE: This study evaluated an eating disorder intervention multimedia program modeled after self-help eating disorder treatment programs. It was hypothesized that women who completed the program would increase their body satisfaction and decrease their preoccupation with weight and frequency of disordered eating behaviors. METHOD: Participants were 57 undergraduate females randomly assigned to either the intervention or control group. Psychological functioning was assessed at baseline, at 3 months postintervention, and at 3 months follow-up. RESULTS: Intervention group subjects significantly improved their scores on all psychological measures over time. When compared to the control group, however, only the intervention group's improvements on the Body Shape Questionnaire were statistically significant. DISCUSSION: This study has demonstrated that minimally effective eating disorder intervention programs can be delivered. A revised program that eliminates interface problems and increases the structure of the intervention is likely to be even better received and more effective.

Repetitive strain injury. 2. Diagnostic and treatment tips on six common problems. The Goff Group.

Repetitive strain injury is caused by recurrent overuse, resulting in microtrauma to tissues. Local pain and tenderness, weakness, inflammation, and limited function are common findings. Some of the strain injuries seen most often are carpal tunnel syndrome, trigger finger, shoulder impingement syndrome, tennis elbow, thoracic outlet syndrome, and myofascial pain disorders. Often, treatment can be started at the initial visit, after systemic disorders have been ruled out. A vital step is elimination of aggravating factors, such as improper posture, inadequate attention to ergonomic factors at work, and contributory habits (e.g., jaw or hand clenching). Use of simple joint-protection measures can alleviate much of the discomfort. Appropriate self-help strategies used at home may restore flexibility and strength with a minimum of medical intervention, but pain relief must be achieved before patients can be expected to follow through with rehabilitation efforts. Use of ice packs, massage, NSAIDs, or topical pain-relief agents is often helpful. Prompt, temporary pain relief can also be achieved with injection of a local anesthetic-corticosteroid mixture. Persistent disability should prompt consideration of psychosocial factors. In addition, fraudulent claims of disability do occur. Although physicians should make every effort to support legitimate claims of work-related injury, they should also be aware of the possibility that activities outside of work (e.g., sports participation, accidental injuries) may be contributing factors.

[Particular features of the treatment of ulcer recurrence in patients with myocardial infarction].

107 patients with myocardial infarction and ulcer recurrence were examined. It was revealed that the ulcerous process proceeded with focal trombohemorragic disorders of local microcirculation in the gastroduodenal mucous coat in severe cases of myocardial infarction and with tromboischemic disorders of terminal blood flow in extremely severe cases. It was accompanied by the activation of acid and pepsin production, depression of mucopolysaccharides production and hypermotor gastric dyskinesis in patients with severe coronary pathology, in patients with the extremely severe pathology--by the depression of all functions of the stomach, except for normal acid production. The administration of an antiulcerous therapy helped to reduce the period of elimination of ulcer recurrence symptoms, liquidated microcirculatory and gastric functional disorders, and promoted the healing of ulcers. The therapy included omeprazole, sucralfate, long-term form of nifedipine for patients with severe myocardial infarction, and ranitidine, sucralfate and doxazosin in common doses for 20-25 days for patients with extremely severe cases.

[The cytogenetic indices of participants in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station and their correction].

An analysis was performed of cytogenetic homeostasis in liquidators of the Chernobyl accident after-effects, which led to the belief that if the above contingent of subjects continue living in large industrial regions characterized by high levels of environmental contamination with industrial waste, such as that formed in the chemical, by-product coke, and metallurgical industries, they will not dispel disorders of the cytogenetic homeostasis (chromosomal and chromatic aberrations), which fact is believed to be due to the inhibition of the processes of elimination of somatic cells with a faulty genotype. Proposed for the correction of cytogenetic disorders are such options as a complex of antioxidants and intravascular laser irradiation of blood, that will, we believe, help in restoring the cytogenetic homeostasis.

Idiopathic neonatal giant cell hepatitis presenting with acute hepatic failure on postnatal day one.

We report a term male infant presenting on postnatal day 1 with fulminant hepatic failure. Described congenital infection, metabolic disorders, and cardiovascular etiologies of acute neonatal liver failure were assessed and eliminated. A liver biopsy on postnatal day 10 showed neonatal giant cell hepatitis (NGCH) with an unusual degree of fibrosis for this early postnatal age. NGCH is a clinical diagnosis of cholestatic disorders of unknown etiology in the newborn, and, to our knowledge, has not been previously associated with immediate neonatal hepatic failure. The giant cell transformation is a common response to a variety of insults and only rarely occurs beyond the neonatal period. Most cases present with cholestatic jaundice and varying degrees of coagulopathy, and, many, as in this case, show progressive resolution.

The ethical and moral implications of sexual classification: a commentary.

This paper reviews the relationship between psychiatric diagnosis and morality, suggesting that moral reasoning has been the primary determinant in the diagnosis of sexual disorders. It suggests two hypotheses to explain why homosexuality was eliminated from DSM. One, that homosexuality is now viable as a lifestyle and therefore has become socially regulated; and two, that the normal is the intractible. It further suggests that there is no scientific reason to keep the paraphilias in DSM.

Chronic rejection: risk factors, regulation, and possible sites of therapeutic intervention.

Clinical chronic rejection corresponds histologically to proliferative allograft vasculopathy. This disorder reflects the cumulative trauma to the allograft regardless of its origin. As a consequence of trauma, inflammation is generated, leading to endothelial and smooth muscle cell activation, smooth muscle replication and migration, and graft arterial intimal thickening. According to the current paradigm, chronic rejection can be avoided by more intensive and selective immunosuppression and by avoiding the known predisposing factors. Retransplantation experiments in experimental animals to donor or F1-strain suggest, however, that elimination of histoincompatibility does not prevent the progression of the disorder once it has been initiated. To design additional sites of intervention after the "point-of-no-return," attention has been focused on the regulation of the synthesis of growth factors, binding of the growth factors to the receptors, and to signalling downstream of the receptor. Also, inhibition of proteolytic enzymes, necessary for the locomotion of the smooth muscle cells, is a possible target. On most occasions, however, the inhibitory effect is at the most 30 to 50% of the maximal, and only the future will show whether several of these approaches must be applied concomitantly or whether genes regulating several of these processes simultaneously can be identified and exploited.

Stress and consumption: inescapable shock, neophobia, and quinine finickiness in rats.

Exposure to inescapable shock has been shown to result in reduced consumption of quinine in water (the finickiness effect) in rats. In the present experiment, (a) a clear difference in finickiness occurred between male adult rats exposed to inescapable shock and those exposed to escapable shock (the first such demonstration), (b) finickiness was reinstated 20 days later, and (c) finickiness was eliminated by quinine exposure prior to treatment. The first 2 results support the role of uncontrollability and/or unpredictability in finickiness and extend its potential impact to long-term consequences. This allows greater potential for the modeling of long-term effects, such as eating disorders and depression in humans. The finding that preexposure to quinine eliminated finickiness is contrary to current accounts of the effect. Accounts of finickiness are proposed in terms of classically conditioned aversions, bitterness, and neuropeptide control of ingestion.

Fluoxetine once every third day in the treatment of major depressive disorder.

OBJECTIVE: Fluoxetine and its active metabolite norfluoxetine have long half-lives. We postulate that, owing to the long elimination half-life and the time to reach steady-state level in plasma is nearly four weeks, patients diagnosed with major depressive disorder might be treated with fluoxetine taken once every third day, after being treated initially during 4 weeks with daily doses of fluoxetine. METHODS: In this open label, 12-weeks, randomized, prospective study, patients diagnosed with DSM-IV major depressive disorder were randomly assigned into 1 of 3 treatment groups. Thirty-four patients took 20 mg and 32 patients took 40 mg of fluoxetine daily throughout the study. Twenty-nine patients had been taking 20 mg of fluoxetine daily for 4 weeks of the study initially, and then were switched to 20 mg fluoxetine once every third day regime. The severity of depression was assessed by Hamilton Depression Rating Scale (HDRS) and Clinical Global Impressions- Severity Scale (CGI-S). Response was defined as a 50% or greater reduction of the baseline HDRS total score. After defining a strict criterion of relapse, time to relapse was estimated using survival analyses (Kaplan-Meier method). RESULTS: The repeated measures analysis of variance (ANOVA) of HDRS found a significant time effect (F = 464.04, df = 1.00, p < 0.001), but no significant group effects (F = 0.84, df = 2.00,p = 0.433) from baseline through week 12. The proportion of responders was not significantly different between the treatment groups at the endpoint. Survival analyses showed, however, a significant delayed mean time to relapse in patients treated with 40 mg of fluoxetine daily compared to either patients treated with 20 mg of fluoxetine daily or 20 mg fluoxetine once every third day. The mean times to relapse were 79.8, 70.8, and 70.5 days, respectively. Fluoxetine was associated with some adverse events in 46.3% of patients. The most frequently occurring adverse event was insomnia. CONCLUSION: It is proposed that either every third day or daily dosing with the same dose of fluoxetine could treat the patients with major depressive disorder during the acute and continuation period of treatment. Nevertheless, higher daily dose of fluoxetine has a reduced relapse rate compared to that of the lower daily dose.

Thyroid issues in reproduction.

Observations in people and animals demonstrate relationships between thyroid and reproductive functions. Thyroid issues of importance to small animal reproduction are twofold. First, some thyroid disorders, such as lymphocytic thyroiditis and some forms of congenital hypothyroidism, appear to be heritable. Those traits might be considered undesirable. If so, to eliminate the trait affected animals would not be selected as breeding stock. Second, thyroid disorders may adversely affect fertility, pregnancy, or neonatal health. If a causal relationship existed between thyroid and reproductive disorders, correction of one would be expected to result in resolution of the other. This is often not the case. Although animals and people with thyroid disorders may also have reproductive disorders, usually disorders other than thyroid disease are the cause of reproductive abnormalities. It appears that euthyroidism supports optimal reproductive performance, but clinically significant reproductive dysfunction is manifested only under certain uncommon conditions of thyroid disease in dogs and cats.

Rituximab therapy for multisystem autoimmune diseases in pediatric patients.

OBJECTIVE: To evaluate the effects of rituximab (anti-CD20 monoclonal antibody) on the disease course in pediatric patients with multisystem autoimmune diseases. METHODS: Four patients with multisystem autoimmune diseases refractory to conventional immunosuppressive medications, each with central nervous system (CNS) involvement, were treated with four weekly infusions of rituximab. Their clinical and laboratory responses were evaluated. RESULTS: Each of the patients had improvement in clinical symptoms and laboratory parameters. One patient with autoimmune cytopenias and autoimmune CNS and peripheral nervous system disease had resolution of the cytopenias and marked improvement in neurologic symptoms; he currently receives no immunosuppressive medications. Two half-siblings with lymphoplasmacytic colitis, pulmonary nodules, and CNS disease had improvement of their symptoms. A fourth patient with chorea and seizures secondary to primary antiphospholipid antibody syndrome had improvement in fine and gross motor function and reduced seizure frequency. There were no serious adverse events. CONCLUSIONS: The biologic response modifier rituximab, designed to eliminate B lymphocytes, was safe and effective in four pediatric patients with multisystem autoimmune disorders. It appears to be beneficial in autoimmune conditions presumably mediated by a variety of B-cell-related mechanisms, and may decrease or eliminate the need for other immunosuppressive medications.

Mitochondrial DNA analysis: polymorphisms and pathogenicity.

The investigation of mtDNA disease can be relatively straightforward if a person has a recognisable phenotype and if it is possible to identify a known pathogenic mtDNA mutation. The difficulties arise when no known mtDNA defect can be found, or when the clinical abnormalities are complex and not easily matched to those of the more common mitochondrial disorders. We will describe here the difficulties that can be encountered during the identification of pathogenic mtDNA mutations and the approaches that can be used to confirm, or eliminate, a likely pathogenic role, in either single gene diseases or in multifactorial disorders.

The infrequency of "pure culture" diagnoses among the anxiety disorders.

BACKGROUND: Anxiety disorders are known to commonly coexist in individuals, both with other anxiety disorders and with mental disorders from other groupings, such as affective disorders. We questioned how frequently anxiety disorders actually occur in isolation, as "pure cultures." METHOD: We examined diagnostic patterns among the 711 subjects entered into a large, multicenter study of anxiety disorders, the Harvard/ Brown Anxiety Disorders Research Program (HARP), which focused on panic, agoraphobia, generalized anxiety disorder, and social phobias as "index disorders" required for intake. RESULTS: We used various definitions for "pure culture." By all definitions, subjects with "pure culture" represented a minority, especially in cases of generalized anxiety disorder and social phobia, where comorbidity was virtually ubiquitous. "Pure culture" status was associated with later onset of illness and less chronicity. CONCLUSION: Future studies of anxiety disorder should aim to document the extensive comorbidity, rather than eliminate it by restrictive diagnostic exclusion criteria, lest they yield atypical or even misrepresented groups of patients. Clinicians should not stop at identifying only the "main" diagnosis but look for other, comorbid diagnoses that are often present.

Aup1, a novel gene on mouse chromosome 6 and human chromosome 2p13.

We have cloned a novel mouse cDNA, Aup1, encoding a predicted protein of 410 amino acid residues. The 1.5-kb Aup1 transcript is ubiquitously expressed in mouse tissues. An evolutionary relationship to the Caenorhabditis elegans predicted protein F44b9.5 is indicated by the 35% identity and 53% conservation of the amino acid sequences. Nineteen related human ESTs spanning 80% of the protein have also been identified, with a predicted amino acid sequence identity of 86% between the human and the mouse proteins. The gene has been mapped to a conserved linkage group on human chromosome 2p13 and mouse Chromosome 6. Aup1 was eliminated as a candidate gene for two closely linked disorders, human LGMD2B and mouse mnd2.

Assessment of drug metabolism in hepatic disease: comparison of plasma kinetics of oral cyclobarbital and the intravenous aminopyrine breath test.

The exhalation of 14CO2 derived from an i.v. tracer dose of [dimethylamine-14-C]aminopyrine has been investigated in normal controls and patients. They subsequently ingested 200 mg cyclobarbital calcium in the evening and the decline in the plasma drug level over the following 2 days was measured by thin-layer chromatography. The peak specific activity of exhaled 14CO2 occurred 0.5-2 h after 14C-aminopyrine injection in the absence of liver disease and in non-cirrhotic liver disorders. It was delayed in certain patients with cirrhosis. Compared to 8 medically healthy subjects, 10 patients with acute viral hepatitis, 8 with cirrhosis and 10 with fatty liver exhibited a significantly increased half-life of 14CO2 exhalation. Normal mean values were found in 12 patients with non-cirrhotic alcoholic liver disease and in 14 patients with non-hepatic diseases. The cyclobarbital (CB) half-life was prolonged and the clearance reduced in patients with viral hepatitis, cirrhosis or alcoholic liver damage as compared to data from 17 control subjects. Due to a larger apparent volume of distribution, patients with fatty liver disease had an increased CB half-life, although its clearance was normal. A close negative correlation was detected between the clearance and the logarithm of the CB level measured 36 h after drug ingestion. The oral CB test evaluated from a single blood sample taken about 36 h after drug administration appears to be a useful indicator of human drug metabolising capacity. Discrimination between patients with and without disordered liver function was similar in the two drug elimination tests.

Patient-reported erectile dysfunction: a cross-validation study.

Previous work highlighting a significant correspondence between patient-reported sex history information and physiological indices of erectile functioning was cross-validated. The matched sample comprised of 46 older male veterans presenting with erectile dysfunction, with many experiencing chronic physical illnesses. All subjects underwent a comprehensive medical and psychological evaluation, followed by 2 consecutive nights of in-hospital Rigiscan diagnostic monitoring, to evaluate penile rigidity, tumescence, and duration of erectile episodes. Stringent criteria were employed to control for confounding of Rigiscan results, with elimination from the study for affective, thought, or sleep disorders. Results from the multiple regression analyses showed that patient reports of AM erections and erectile quality accounted for significant proportions of the variance in the Rigiscan criterion measures, with 3 of the 4 R2 values falling within the Herzberg criterion for cross-validation. Results confirm the diagnostic significance of patient self-report for the population of older, chronically ill men who present with impaired erectile functioning.
