Buprenorphine responders: a diagnostic subgroup of heroin addicts?

1. A 26-32 month follow-up of 16 heroin-dependent subjects who entered a pilot trial of treatment with buprenorphine (a mixed agonist/antagonist) suggests that positive response to treatment may identify a subgroup of untreated addicts whose levels of psychosocial functioning are intermediate between those for whom methadone (a pure agonist) or naltrexone (a pure antagonist) would be indicated. 2. Buprenorphine's pharmacologic profile provides a missing link in available modalities for opiate dependence treatment, making it acceptable for many addicts who will not accept methadone maintenance treatment, join a residential therapeutic community, or be successful on naltrexone treatment. 3. Eight of the 16 ss were abstinent from heroin while receiving 0.6-3.9 mg/day buprenorphine and counseling. Responders (mean age 34 yrs) had been heroin dependent for a mean of 9.5 years (range 6-17 yrs), all were self-supporting, 4 lived with a non-addicted spouse, 5 had no prior treatment for addiction and 3 had prior naltrexone treatment, but had discontinued it and relapsed. Non-responders (mean age 30 yrs) had been heroin dependent for a mean of 7.4 yrs (range 2-19 yrs), 7 had no regular employment, all were single and 7 had no prior treatment for addiction. 4. Levels of psychosocial functioning (work, home, leisure) and global assessments of functioning were significantly higher for buprenorphine responders than non-responders (p less than .001 and p less than .01 respectively). 5. A new formulation of buprenorphine needs to be developed for addiction treatment, ideally consisting of 0.5 mg and 2.0 mg sublingual tablets.     

Three-dimensional computed tomographic analysis of the normal temporomandibular joint

Ten temporomandibular joints, obtained from three asymptomatic patients and two cadavers, were examined by three-dimensional computed tomography. The osseous components of the condylar process of the mandible and the glenoid fossa of the temporal bone were well visualized. The meniscus was visualized in both the closed- and the open-mouthed positions. Advantages and disadvantages of the technique are discussed.     

Diagnoses of the relatives of schizotypal outpatients

Relatives of 22 schizotypal probands were evaluated for lifetime psychiatric diagnoses. Forty-four (N = 44) of the 97 available relatives were interviewed directly using the Diagnostic Interview Schedule. The rates of psychiatric diagnoses were compared with those of sixty-six (N = 66) of 140 relatives of 30 depressed patients. Family history of mental illness was ascertained by the informant method on the remainder of relatives of both proband groups. The rate of depression found in the relatives of schizotypal patients was 52% in those directly interviewed and 25.7% when informants' reports on unavailable relatives are pooled with direct interview data. These rates were not significantly higher than those found for the relatives of depressed probands (34.8% by direct interview and 21% including reports from informants). The high rates of depression in the relatives of schizotypal probands may indicate that schizotypal personality is associated with affective disorder and not only with schizophrenia. However, the high rates may be due to the presence of depressive character traits in relatives, which inflate the rates of dysthymic disorder and other chronic depressive disorders in the relatives of borderline patients.     

Tropical spastic paraparesis-like illness occurring in a patient dually infected with HIV-1 and HTLV-II

We describe a 34-year-old man from southern Florida with a history of intravenous drug use, dually infected with human immunodeficiency virus type 1 (HIV-1) and human T-lymphotropic virus type II (HTLV-II), who developed a myelopathy clinically indistinguishable from HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). This myelopathy was characterized by spastic lower extremity weakness, distal paresthesias, sensory loss with a discrete thoracic level to pinprick, back pain, impotence, and sphincter disturbances. Nerve conduction studies revealed an associated mixed axonal and demyelinative neuropathy. Despite a lack of response to 10 months of zidovudine therapy, the myeloneuropathy improved dramatically 2 years after its onset in the absence of any therapeutic intervention.     

Polyostotic fibrous dysplasia of the cervical spine: case report and review of the literature.

BACKGROUND CONTEXT: Multiple lytic lesions of the spine usually represent metastatic or infectious disease processes. PURPOSE: To describe an extremely rare presentation of an uncommon disease process. STUDY DESIGN/SETTING: Case report/university hospital. METHODS: We describe the management of a patient who presented with a pathological fracture of C3 and multiple lytic lesions of the cervical spine. RESULTS: After reconstructive surgery, the final pathological diagnosis was fibrous dysplasia. CONCLUSION: Fibrous dysplasia is rarely seen in the cervical spine and may mimic other pathological processes. The surgical and medical management of spinal fibrous dysplasia is described.     

Treatment of myofascial trigger points in common shoulder disorders by physical therapy: A randomized controlled trial [ISRCTN75722066]

Background  

Shoulder disorders are a common health problem in western societies. Several treatment protocols have been developed for the clinical management of persons with shoulder pain. However available evidence does not support any protocol as being superior over others. Systematic reviews provide some evidence that certain physical therapy interventions (i.e. supervised exercises and mobilisation) are effective in particular shoulder disorders (i.e. rotator cuff disorders, mixed shoulder disorders and adhesive capsulitis), but there is an ongoing need for high quality trials of physical therapy interventions. Usually, physical therapy consists of active exercises intended to strengthen the shoulder muscles as stabilizers of the glenohumeral joint or perform mobilisations to improve restricted mobility of the glenohumeral or adjacent joints (shoulder girdle). It is generally accepted that a-traumatic shoulder problems are the result of impingement of the subacromial structures, such as the bursa or rotator cuff tendons. Myofascial trigger points (MTrPs) in shoulder muscles may also lead to a complex of symptoms that are often seen in patients diagnosed with subacromial impingement or rotator cuff tendinopathy. Little is known about the treatment of MTrPs in patients with shoulder disorders.
