Facial Aesthetics in Young Adults after Cleft Lip and Palate Treatment over Five Decades.

Cleft Lip and Palate (CLP) - a common facial malformation in newborns - is typically corrected by surgical intervention to allow for normal speech development, psychosocial adjustment, and facial attractiveness. The long term treatment outcome can be evaluated after a number of years, possibly in adulthood. We investigated the aesthetics of the nasolabial region by subjective ratings. To compare various surgical approaches we recruited 12 raters to evaluate 429 patients. Expert and lay raters judged photographs from patients, who have completed treatment with one of three different surgical strategies performed in our institution over 50 years. Facial photographs were cropped, presented to the raters in a randomized sequence, and judged by the raters on a 5 point Likert scale. The subjective ratings between the raters revealed a fair to substantial inter-rater reliability. The average ratings of the surgical outcome improved continuously over the investigated 5 decades. Despite possible differences between raters and rater groups this overall result was consistently seen in the gender groups (male/female), or expertise related groups (expert/lay). Our analysis revealed that patients with bilateral CLP scored worse than patients with unilateral CLP when treated in the fifties; more recently treated patients of both groups scored similarly.

Dynamic 1.5-T vs 3-T true fast imaging with steady-state precession (trueFISP)-MRI sequences for assessment of velopharyngeal function.

OBJECTIVES: To compare the image quality of MRI scans produced with 1.5- and 3.0-T devices during functional test condition. METHODS: 65 MRI scans obtained with 1.5- (n = 43) or 3.0-T (n = 22) true fast imaging with steady-state precession (trueFISP) sequences from patients with a history of a cleft palate were evaluated. Two experts assessed the MRI scans, independently of each other, and blinded to the MRI technique used. Subjective ratings were entered on a five-point Likert scale. The median planes of three anatomical structures (velum, tongue and pharyngeal wall) were assessed in three functional states (at rest, during phonation of sustained "e" and during articulation of "kkk"). In addition, MRI scans taken during velopharyngeal closure were evaluated. RESULTS: Under blinded conditions, both observers (radiologist and orthodontist) independently rated the quality of 1.5-T scans higher than that of 3.0 T. Statistical analysis of pooled data showed that the differences were highly significant (p < 0.009) in 4 out of 10 test conditions. The greatest differences in favour of 1.5 T were observed for MRI scans of the velum. CONCLUSIONS: 1.5 T used with trueFISP may be preferable over 3.0-T trueFISP for the evaluation of the velopharyngeal structures in the clinical routine.

Neonatal abstinence syndrome in European and North American neonates: differences in clinical characteristics derived from a prospective randomized trial.

BACKGROUND: Due to the steady increase of substance-dependent pregnant women the neonatal abstinence syndrome has become an increasingly important issue in neonatology. The present study investigates site-specific differences of detailed symptoms and treatment of neonatal abstinence syndrome within the context of an international multicenter clinical trial. METHODS: Site specific neonatal data analyses from a prospective randomized, double-blind, double-dummy clinical trial (MOTHER study) was performed. A standardized NAS rating and treatment protocol was applied, while non-pharmacological care of NAS symptoms differed across the sites. RESULTS: Urban US neonates exhibited most neurological symptoms (p<0.001) while in Europe autonomous, respiratory and gastrointestinal symptoms were found significantly more often compared to urban and/or rural US (p<0.05). Methadone produced significantly greater scores than buprenorphine in neurological, behavioural and respiratory symptoms regardless of the sites (ps<0.05). NAS treatment rates in all site clusters were similar for methadone-exposed neonates, while in Europe significantly more buprenorphine-exposed neonates were treated (p=0.001) than in US site clusters. Urban US neonates had significantly higher NAS scores (p<0.01) compared to rural US and European neonates, and needed significantly higher morphine doses (p<0.05) with longer treatment duration. Birth weight, length and head circumference did not differ significantly among the site clusters, but APGAR scores were significantly higher in European (p<0.01) neonates. CONCLUSION: In addition to intrauterine medication exposure other aspects such as different addiction severity of the mothers, different treatment modalities including rooming-in as well as the frequency of NAS ratings may be influencing the course of NAS.

Training of affect recognition (TAR) in schizophrenia--impact on functional outcome.

Deficits in facial affect recognition as one aspect of social cognitive deficits are treatment targets to improve functional outcome in schizophrenia. According to preliminary results antipsychotics alone show little effects on affect recognition. A few randomized intervention studies have evaluated special psychosocial treatment programs on social cognition. In this study, the effects of a computer-based training of affect recognition were investigated as well as its impact on facial affect recognition and functional outcome, particularly on patients' quality of life. Forty clinically stabilized schizophrenic patients were randomized to a six-week training on affect recognition (TAR) or treatment as usual including occupational therapy (TAU) and completed pre- and post-treatment assessments of emotion recognition, cognition, quality of life and clinical symptoms. Between pre- and post treatment, the TAR group achieved significant improvements in facial affect recognition, in particular in recognizing sad faces and, in addition, in the quality of life domain social relationship. These changes were not found in the TAU group. Furthermore, the TAR training contributes to enhancing some aspects of cognitive functioning and negative symptoms. These improvements in facial affect recognition and quality of life were independent of changes in clinical symptoms and general cognitive functions. The findings support the efficacy of an affect recognition training for patients with schizophrenia and the generalization to social relationship. Further development is needed in the impact of a psychosocial intervention in other aspects of social cognition and functional outcome.

Peripartum pain management in opioid dependent women.

Increased pain sensitivity and the development of opioid tolerance complicate the treatment of pain experiencedby opioid maintained pregnantwomenduring delivery and the perinatal period. Theaim of the present study was to investigate differences in pain management of opioid maintained compared to nondependent pregnant women during delivery and the postpartum period. 40 deliveries of 37 opioid dependent women enrolled in a double-blind, double-dummy randomized controlled trial (RCT) examining the safety and efficacy of methadone (mean dose at the time of delivery = 63.89 mg) and buprenorphine (mean dose at the time of delivery = 14.05 mg) during pregnancy were analyzed and participants were matched to a non-dependent comparison group of 80 pregnant women. Differences in pain management (opioid and non-opioid analgesic medication) during delivery and perinatal period were analyzed. Following cesarean delivery opioid maintained women received significantly less opioid analgesics (day of delivery p = 0.038; day 1: p = 0.02), NSAIDs were administered more frequently to opioid dependent patients than to the comparison group during cesarean section and on the third day postpartum. Significantly higher nicotine consumption in the group of opioid dependentwomenhad a strong influence onthe retrieved results, and might be considered as an independent factor of altered pain experience. Differences in pain treatment became evident when comparing opioid maintained women to healthy controls. These differences might be based on psychosocial consequences of opioid addiction along with the lack of an interdisciplinary consensus on pain treatment protocols for opioid dependent patients.

Facial aesthetics and the assignment of personality traits before and after orthognathic surgery.

Processing and interpreting the face is generally very important because one is often required to make rapid decisions in life on the basis of meagre information. Ninety-two volunteers used a computer-assisted test battery to assess 40 profiles of patients (8 skeletal Class II and 8 skeletal Class III patients, each pre- and postoperatively, with 8 skeletal Class I photographs serving as controls). On a 7-point Likert scale the raters were asked to evaluate aesthetics and a few relevant personality traits (e.g. unintelligent, inhibited, aggressive, brutal). The photographs of the two patient groups were rated significantly less attractive and intelligent prior to surgery than the photographs of the control group. In respect of personality traits, the photographs of the skeletal Class III group differed more strongly from normal ones. In respect of aesthetics and intelligence, both patient groups benefited markedly from surgery. For some personality traits, significant interactions were found between the two groups on pre-post comparison. The method underlying the study is useful for evaluating the outcome of orthognathic surgery, but also indicates the strongly generalized and unconscious processes involved in the estimation of people's personality traits, especially when these concern deviations from the socially normal condition.

Validation of the German version of the brief assessment of cognition in Schizophrenia (BACS) - preliminary results.

The German version of the BACS showed high test-retest reliability. Sensitivity and specificity scores demonstrated good ability to differentiate between patients and controls. The study suggests that the German Version of the BACS is a useful scale to evaluate cognitive functioning.

[Quality of life five years after total or partial knee arthroplasty]. / Lebensqualität von Patienten fünf Jahre nach Knie-Arthroplastik.

AIM: Multiple aspects of health-related quality of life were assessed in elderly patients after total or partial knee arthroplasty. METHOD: 187 subjects who had undergone knee arthroplasty 5 years ago were asked to fill out 3 questionnaires, the Nottingham Health Profile, the SF-36 Health Survey and the Funktionsfragebogen Hannover. Results were compared to standard data. The impact of gender and age was analyzed, and 3 different types of prostheses were compared. RESULTS: Response rate was 74 % (n = 138). Regarding the main symptoms pain and subjective function, as well as almost all other aspects, quality of life proved to be significantly reduced compared to the age-matched general population. Correlations between age and quality of life scales were low. Different types of implants led to similar results in all scales but one. CONCLUSION: 5 years after knee arthroplasty the quality of life is markedly reduced compared to the general population. The impact of age, gender, and type of implant is low. In our sample, the SF-36 showed methodological advantages compared to the NHP for the measurement of subjective pain and function.

Prevalence and distribution of hepatitis C subtypes in patients with opioid dependence.

UNLABELLED: AIM AND SETTING: The drug addiction out-patient clinic at the University Hospital for Psychiatry in Vienna performed a study to identify the prevalence of hepatitis C virus (HCV) infections in a group of opiate-dependent patients, to detect the distribution of HCV subtypes and to calculate the comorbidity of human immunodeficiency virus (HIV) and hepatitis B virus (HBV). DESIGN AND PARTICIPANTS: We consecutively investigated unselected patients (n = 173) during an observation period of 2 months with the diagnosis of opioid dependence (DSM-IV: 304.0) and polysubstance dependence (DSM-IV: 304.9). MEASUREMENTS: Blood was investigated focusing on liver enzymes and on viral status including HIV, hepatitis B and hepatitis C, followed by subtyping of the virus. FINDINGS: In 80.3% hepatitis C antibodies were found, 66.5% were HCV RNA (PCR) positive. 3a was the most frequent subtype (35.6%), followed by 1a (28.8%) and 1b (22.0%). Four patients had both subtypes 1a and 1b (6.8%), 3 were 2b positive (5.1%) and 1 patient had subtypes 2a/2c (1.7%). No significant difference in aspartate (AST) and alanine aminotransferases (ALT) concerning the different subtypes (AST: p = 0.290; ALT: p = 0.260) could be calculated; 11.6% showed co-infection with HIV, 2 patients had a chronic infection with hepatitis B. CONCLUSIONS: The rate of HCV infection in substance-dependent patients at our drug addiction out-patient clinic is extremely high. The distribution of subtypes showed a relatively homogeneous distribution of the types 1a, 1b and 3a. The recommended therapy with alpha-interferon should be initiated in drug-dependent patients under considerations of an enrollment in oral maintenance with synthetic opioids.

Treatment of opioid-dependent pregnant women with buprenorphine.

AIMS: To assess the maternal and fetal acceptability of buprenorphine and neonatal abstinence syndrome (NAS) in children born to buprenorphine-maintained mothers. DESIGN AND SETTING: Open-label, flexible dosing, inpatient induction with outpatient maintenance, conducted at the University of Vienna within the existing pregnancy and drug addiction program. PARTICIPANTS: Fifteen opioid-dependent pregnant women. INTERVENTION: Sublingual buprenorphine tablets (1-10 mg/day). MEASUREMENTS: Mothers: withdrawal symptoms (Wang Scale), nicotine dependence (Fagerström Scale: FTQ) and urinalysis. Neonates: birth outcome and NAS (Finnegan Scale). FINDINGS: All subjects were opioid-, nicotine- and cannabis-dependent. Buprenorphine was well tolerated during induction (Wang Score < or = 4) and illicit opioid use was negligible (91% opioid-negative). All maternal, fetal and neonatal safety laboratory measures were within normal limits or not of clinical significance. Mean birth outcome measures including gestational age at delivery (39.6 +/- 1.5 weeks), Apgar scores (1 min = 8.9; 5 min = 9.9; and 10 min = 10), birth weight (3049 +/- 346 g), length (49.8 +/- 1.9 cm) and head circumference (34.1 +/- 1.8 cm) were within normal limits. The NAS was absent, mild (without treatment) and moderate (with treatment) in eight, four and three neonates, respectively. The mean duration of NAS was 1.1 days. CONCLUSIONS: Buprenorphine appears to be well accepted by mother and fetus, and associated with a low incidence of NAS. Further investigation of buprenorphine as a maintenance agent for opioid-dependent pregnant women is needed.

[Buprenorphine vs. methadone as maintenance treatment for opioid dependence]. / Vergleichsuntersuchung von Buprenorphin und Methadon im Rahmen der Erhaltungs-therapie Opiatkranker.

The efficacy of buprenorphine in opioid dependent patients (n = 20) was compared to methadone maintained subjects (n = 20) in a randomized comparison trial. Sublingual application of buprenorphine as an alternative synthetical opioid is being compared to methadone during a 24 week study period. A trend (p = 0.06) could be found in the retention rate of investigated patients being maintained on a mean dosage of 63 mg oral applicable methadone (racemat of L- and D-methadone) in comparison to the group on a mean dosage of 7.3 mg buprenorphine (sublingual tablets). The dropout-rate of 11 subjects at the end of the study in the buprenorphine group was higher when compared to the dropout-rate of 5 in the methadone group. There was no significant difference between the two groups over the treatment period in respect to additional consumption of opiates, benzodiazepines and cocaine as evaluated through urine toxicology. The result in regard to compliance over the study period demonstrates that methadone appears to be the more successful oral opioid (p = 0.04). Nevertheless, efficacy of buprenorphine in maintenance could be demonstrated in the remaining subjects, and further studies with higher daily doses and a higher number of subjects have to be performed.

Comparison of methadone and slow-release morphine maintenance in pregnant addicts.

AIMS: To investigate whether the neonatal abstinence syndrome (NAS) is different in children born to women maintained on slow-release morphine, compared with those maintained on methadone, and to compare additional drug consumption in these groups of women. DESIGN, SETTING AND PARTICIPANTS: An open, randomized trial was conducted in an established clinic. Forty-eight pregnant women who presented to the clinic as opiate or polysubstance abusers were enrolled and maintained on either methadone (24 women) or slow-release morphine (24 women) up to and following delivery. The programme included psychosocial therapy and support for their opiate-addicted partners. MEASUREMENTS: Standard urinalysis methods were used to measure consumption of cocaine and benzodiazepines during pregnancy. Injection sites were monitored to indicate additional opiate use. NAS was measured according to Finnegan score and the amount of phenobarbiturates prescribed to alleviate the symptoms. FINDINGS: No difference was found in the number of days that NAS was experienced by neonates born to methadone or morphine maintained mothers (mean = 16 and 21 days, respectively). All children were born healthy and no serious complications arose. Fewer benzodiazepines (p < 0.05) and fewer additional opiates (p < 0.05) were consumed by the morphine-maintained women compared with those who took methadone, but no difference was seen in cocaine consumption. Nicotine consumption was reduced significantly in both groups during pregnancy (p < 0.02). CONCLUSIONS: Both methadone and morphine are suitable maintenance agents for pregnant opiate addicts. Maintenance agents that result in a less prolonged NAS should be studied in further trials.

Buprenorphine versus methadone maintenance for the treatment of opioid dependence.

AIMS: To evaluate the effectiveness of buprenorphine compared with methadone maintenance therapy in opiate addicts over a treatment period of 24 weeks. DESIGN: Subjects were randomized to receive either buprenorphine or methadone in an open, comparative study. SETTING: Subjects were recruited and treated at the drug addiction outpatient clinic at the University of Vienna. PARTICIPANTS: Sixty subjects (19 females and 41 males) who met DSM-IV criteria for opioid dependence and were seeking treatment. INTERVENTION: Subjects received either sublingual buprenorphine (2-mg or 8-mg tablets; maximum daily dose 8 mg) or oral methadone (racemic D -/+ L-methadone; maximum daily dose 80 mg). A stable dose was maintained following the 6-day induction phase. MEASUREMENT: Assessment of treatment retention and illicit substance use (opiates, cocaine and benzodiazepines) was made by urinalysis. FINDINGS: The retention rate was significantly better in the methadone maintained group (p < 0.05) but subjects completing the study in the buprenorphine group had significantly lower rates of illicit opiate consumption (p = 0.04). CONCLUSION: The results support the superiority of methadone with respect to retention rate. However, they also confirm previous reports of buprenorphine use as an alternative in maintenance therapy for opiate addiction, suggesting that a specific subgroup may be benefiting from buprenorphine. This is the first comparative trial to use sublingual buprenorphine tablets: previously published comparison studies refer to 30% solutions of buprenorphine in alcohol.

[Evaluating the quality of life before and after implantation of a total hip endoprosthesis]. / Beurteilung der Lebensqualität vor und nach Implantation einer Hüft-Totalendoprothese.

PURPOSE OF THE STUDY: Quality of Life of patients with Total Hip Arthroplasty is analysed before and one year after surgery. The evaluation included the functional capacity of our patients in every day life comparing the preoperative situation with the result one year after surgery. Age and duration of symptoms were analysed with respect to their influence on the success of the procedure. Finally the question should be answered, if clinical examinations and questionnaires concerning Quality of Life result in comparable data. METHOD: 101 patients with an average age of 64.2 years were included into this study. All patients were evaluated preoperatively and one year after surgery using the Harris Hip Score, questionnaires for Quality of Life of the patients included the Nottingham Health Profile and the Functional Questionnaire Hannover. RESULTS: The pre- and postoperative means of the Nottingham Health Profile showed in five of the six dimensions a significant improvement of Quality of Life (pain, mobility, energy, emotional reaction, sleep). Only the scale "social isolation" remained unchanged between the pre- and postoperative situation. The means of the functional capacity according to the Hannover questionnaire improved from 57.92 to 39.79, a highly significant result. The Harris Hip Score was poor in 97% of the preoperative evaluations. This score improved to 80.2% excellent or good, 7.9% fair and 11.9% poor at one year after surgery. Age and duration of symptoms had no influence in any parameter of Quality of Life. A classification of parameters on Quality of Life according to the Harris-Hip-Score at the 1-year results demonstrates a clear grading concerning the excellent and poor results. Based on the patients evaluations a differentiation between good and poor results is not recorded. CONCLUSIONS: The objective evaluation of results after implantation of a total hip joint-endoprosthesis should not be based only on clinical scores (f.e. Harris-Hip-Score). Subjective informations by the patients using questionnaires on Quality of Life (f.e. NHP, FFbH-R) have to be included into these evaluations. The different judgments of the outcome of surgery underline the necessity, not only to use clinical scores but also to include the patients' feeling into the interpretation of the clinical result.

Comparison of buprenorphine and methadone maintenance in opiate addicts.

As a maintenance agent for opioid dependency, buprenorphine offers advantages such as a lower level of dependence and minimal withdrawal symptoms, due to its partial agonist properties at the micro-opioid receptor. Previous studies have shown 8 mg sublingual buprenorphine to be equivalent to 60 mg oral methadone in terms of retention rate and opioid-negative urine levels. In a 24-week, ongoing European study, 34 opioid-dependent subjects were assessed; 16 receiving buprenorphine and 18 methadone. A free dosing schedule was used with no upper limit for methadone dosing but with a maximum buprenorphine dose of 8 mg. Screening prior to the study excluded subjects with polysubstance dependence, somatic disease and/or HIV infection. Primary outcome measures were abstinence from other drugs, for which subjects provided weekly urine samples for analysis of opioids, cocaine and benzodiazepines, and retention in treatment. Patients in the buprenorphine group provided a greater proportion of negative urine samples, in particular cocaine-negative samples, compared with the methadone group, although this was not statistically significant. Retention in the buprenorphine group was significantly lower than in the methadone group, suggesting that the 8 mg buprenorphine limit may have biased the results in favour of methadone, and that this dose may have been too low for those subjects with high levels of dependence. However, buprenorphine is clearly effective in the more motivated subjects and further investigation in this subgroup is recommended.

Buprenorphine maintenance in pregnant opiate addicts.

Opioid maintenance agents such as methadone and slow-release morphine have provided beneficial effects in pregnant opioid-dependent women in both themselves and their child. However, one of the major drawbacks involved with these agents is that they cause an increase in the severity of neonatal abstinence syndrome (NAS) when compared to mothers using heroin. Consequently, a trial was performed to investigate the effects of buprenorphine use during pregnancy. A total of nine pregnant opioid-dependent women were transferred from either a mean daily dose of 39.7 mg methadone or 400 mg slow-release morphine to a mean daily dose of 8.1 mg buprenorphine. The buprenorphine-maintained patients were integrated into an already established outpatient maintenance treatment programme covering all aspects of prenatal and perinatal care. Results demonstrated that buprenorphine administration in opioid-dependent pregnant patients is efficacious and well tolerated. Babies born to buprenorphine-maintained patients had birthweight and Apgar scores within the normal range (2,500-4,500 g and 9-10, respectively) and no evidence of opioid-related NAS was observed. The results from this preliminary study indicate the potential for buprenorphine maintenance therapy in pregnant addicts, although further research is required to confirm this hypothesis.

Psychophysiological reactions in methadone maintenance patients do not correlate with methadone plasma levels.

In methadone maintenance therapy methadone plasma concentrations of 400 ng/ml are necessary to suppress any further opiate action and to provide stabilized maintenance. In a controlled study we have searched for a differentiation in autonomous activation between patients having low and high methadone plasma levels, using static and dynamic pupillometry and habituation of skin conductance response. Results show that there is no difference in psychophysiological response between patients with high (greater than 400 ng/ml) or low (less than 400 ng/ml) plasma levels of methadone. This indicates that there is no reduction in behavioral arousal in patients with high plasma methadone levels. On the basis of these findings, there is no rationale to maintain patients on plasma levels below 400 ng/ml.

Habituation of skin conductance response in a methadone population.

By measurement of the habituation to the skin conductance response (SCR) no reduction of activation could be observed between stable patients in methadone maintenance therapy and healthy normal subjects, but significant differences were obtained between the well-performing group and poly-drug users treated with methadone. The findings are discussed within the context of previous research on outcome of methadone maintenance. Measurement of habituation to SCR is a useful instrument for detecting polydrug addicts in methadone maintenance programmes.
