Drug and alcohol treatment services effective for methamphetamine abuse.

BACKGROUND: Methamphetamine abuse has become a major public health problem as demonstrated by increases in the number of emergency room visits, substance abuse treatment episodes, and arrests attributable to methamphetamine manufacture and abuse. We examine the effectiveness of conventional substance abuse treatment in the recovery of individuals seeking voluntary treatment for methamphetamine abuse. METHODS: At the request of the Iowa Department of Public Health, the Iowa Consortium for Substance Abuse Research and Evaluation contacted clients who had been admitted to voluntary treatment for methamphetamine abuse. Staff from the Consortium asked subjects to volunteer for follow-up interviews at designated intervals following admission. Agency staff conducted interviews based on the Mini International Neuropsychiatric Interview (MINI) at admission and at designated intervals and reported results to the Consortium for analysis. RESULTS: Subjects were predominantly Caucasian and over one half were female with an average age of 30 years. The criminal justice system was a primary referral source. Reported psychiatric symptoms dropped substantially in the first 60 days following admission and appeared to remain low at 6 and 12 months. Most clients reported abstinence and employment and denied arrests at the 6-month interview. Outcomes were not correlated with psychiatric symptoms. CONCLUSIONS: Psychiatric symptoms improved over time with usual substance abuse treatment. There was no evidence that referral by the court system or symptoms of antisocial personality disorder affected outcome. Conventional treatment resulted in sobriety, employment, and fewer arrests at 6 and 12 months following treatment.     

Benign intracranial hypertension and recombinant growth hormone therapy in Australia and New Zealand

Benign intracranial hypertension (BIH) is reported in three children from Australia and one from New Zealand, who were being treated with recombinant human growth hormone (rhGH). Three males and one female, aged between 10.5 and 14.2 y, developed intracranial hypertension within 2 weeks to 3 months of starting treatment. A national database, OZGROW, has been prospectively collecting data on all 3332 children treated with rhGH in Australia and New Zealand from January 1986 to 1996. The incidence of BIH in children treated with growth hormone (GH) is small, 1.2 per 1000 cases overall, but appears to be greater with biochemical GHD (<10IUml ^-1), i.e. 6.5/1000 (3 in 465 cases), relative risk 18.4, 95% confidence interval 1.9-176.1, than in all other children on the database. The incidence in patients with Turner's syndrome was 2.3/1000 (1 in 428 cases). No cases in patients with partial GHD (10–20 IUml ^-1) or chronic renal failure were identified. Possible causative mechanisms are discussed. The authors'practice is now to start GH replacement at less than the usual recommended dose of 14IUm-² week^-1 in those children considered to be at high risk of developing BIH. Ophthalmological evaluation is recommended for children before and during the first few months following commencement of rhGH therapy and is mandatory in the event of peripheral or facial oedema, persistent headaches, vomiting or visual symptoms. The absence of papilledema does not exclude the diagnosis.     

Iotrol versus metrizamide in lumbar myelography: a double-blind study

In a prospective, randomized, double-blind study, 49 patients underwent lumbar myelography using iotrol (24 patients) or metrizamide (25 patients). The diagnostic imaging adequacy of iotrol was comparable with that of metrizamide. After iotrol myelography, adverse reactions were fewer, less severe, and of shorter duration than were those following metrizamide myelography. Thirteen of 24 patients (54%) receiving iotrol reported some adverse reactions compared with 24 of 25 patients (96%) receiving metrizamide. Five moderate and one severe adverse reaction occurred in the group receiving iotrol. Fourteen moderate and eight severe adverse reactions occurred in the group receiving metrizamide. Thirty-eight patients underwent electroencephalography both before and after myelography (19 iotrol and 19 metrizamide). None of the EEGs obtained after iotrol myelography changed from baseline, while seven of the EEGs obtained after metrizamide myelography showed changes from baseline. Iotrol was judged superior to metrizamide as a contrast medium in this patient population.     

Komplikationen der Nagelosteosynthese am proximalen Humerus

In a prospective outcome study, 76 of 116 patients were examined 1 year after reduction and internal fixation of a dislocated humeral head fracture with an antegrade straight intramedullary nailing system using angular and sliding stable interlocking screws. Of these patients, 77% had three- or four-segment fractures according to the Neer classification. The mean absolute Constant-Murley score 1 year after trauma was 70.0±19.7 points. During the observation period, 51 complications occurred in 44 of 76 patients; of these 44 patients, only 27 required therapeutic interventions. The highest frequency of complications was apparent in those with Neer IV fractures (73.7%), while those with Neer III and Neer IV/III fractures had complication rates of 50% and 52.5%, respectively. Patients without complications showed good or excellent functional results, ranging from 78% to 96% (relative Constant-Murley score of the contralateral noninjured side). In patients with complications, the relative Constant-Murley score ranged from 51% to 65%. Despite the high complication rate, the antegrade angular and sliding stable interlocking nail can be considered effective for treating dislocated humeral head fractures. Modifications of the surgical technique for stabilizing the tubercles (additional suture cerclage fixation of fragmented tubercles) and a polyetheretherketone (PEEK) insert in the proximal segment of the nail to prevent the fixation screws from backing out can substantially decrease some of the most frequent complications.     

Microbiologic findings in protracted and chronic enterocolitis]

Novel diagnostic methods (immunoblotting, immunofluorescence test) have been proved to be very sensitive and specific for detecting enteropathogenic bacilli. 28 patients with chronic enterocolitis were investigated. In 50% (14/28) of these patients Yersinia enterocolitica could be visualized in biopsies by immunofluorescence. The serum of 8 patients also contained IgA-antibodies against plasmid encoded released proteins of Y. enterocolitica. This paper reports evidence for persistence of Yersinia bacilli in a group of patients with chronic enterocolitis. Further studies must show, if these results may have therapeutic implications.     

In vitro and clinical feasibility study with an over-the-wire delivery system for pulsed dye laser angioplasty.

The suitability of a pulsed dye laser (504 nm) in experimental and clinical angioplasty was investigated. In an experimental study, the ablation thresholds were 3 J/cm2 +/- 8 (mean +/- standard deviation) for fibrofatty plaque and 25 J/cm2 for calcified tissues under saline. At a radiant exposure of 10 J/cm2 the etch rates were 1.7 microns per pulse +/- 0.3 for media, 2.8 microns/pulse +/- 0.4 for normal intima, and 3.9 microns/pulse +/- 1.1 for fibrofatty plaque (P less than .05). Pressure wave effects with a separation of tissue layers were predominantly localized at the internal elastic lamina. Thermal injury with vacuolations extended 15 microns +/- 6 into adjacent tissue. For clinical study, laser-assisted balloon angioplasty was performed in 10 patients (64 years +/- 14) with occlusions of peripheral arteries using a 9-F multifiber ring catheter. Lesion length ranged from 2 to 12 cm (mean, 7 cm). Laser angioplasty with an 80 mJ/pulse decreased the mean stenosis from 100% to 58% +/- 12% (P less than .005). The ankle-brachial index rose from a median of 0.48 to 0.88 (P less than .001). In 33% of patients, there were subintimal dissections after laser angioplasty. After a mean follow-up of 10.2 months, the overall clinical success was 70% with a primary patency of 78%. The over-the-wire approach with a pulsed dye laser may constitute a safe and feasible tool in laser angioplasty.     

Beauty and the eye of the beholder: social consequences and personal adjustments for facial patients

Patients' pre- and postoperative self-reports were compared with reports of non-medical observers to investigate whether improved self-esteem is a direct result of increased social acceptance in maxillo- and craniofacial patients. Twenty-two children and adolescents undergoing reconstructive surgery for a variety of facial deformities were asked to rate their physical appearance on the Hay's Scale and fill out the Piers-Harris Self-Concept Scale. Their ratings were compared with scores given by a panel of lay volunteers on random presentation of pre- and postoperative photographs of the same patients. Patients rated their appearance as noticeably improved after surgery, their self-esteem rose significantly and they reported more social adeptness and acceptance at home and school. Raters observed only relatively subtle changes. Apparently, quality of life improved for the postsurgical facial patient because of increased self-esteem and confidence, which free him to overcome social barriers.
