Abnormal synovium in the frozen shoulder: A preliminary report with dynamic magnetic resonance imaging

We studied 16 patients (18 shoulders) with frozen shoulders, 8 patients with subacromial impingement syndrome, and 3 healthy volunteers with dynamic magnetic resonance imaging enhanced with gadolinium diethylenetriaminepentaacetic acid. After intravenous contrast was administered, gradient-recalled echo images were obtained in the oblique coronal plane every 11 to 13 seconds for a total period of 4 to 5 minutes. The signal intensity was measured at the periphery of the glenohumeral joint and in the subacromial bursa. The coefficient of enhancement (percent signal increase per second) in the frozen shoulders was 1.33±0.43 (mean ± SD) for the glenohumeral joint and 0.89±0.47 for the subacromial bursa. These values were far greater than those in subacromial impingement syndrome or in the control group, indicating increased blood flow to the synovium in the frozen shoulders. No previous reports have shown a clinical measure related to the pathophysiology of this disease.     

Diabetes in sex offenders

Thirteen diabetic male sex offenders were compared to 13 nondiabetic sex offenders matched on age, education and offense type. A standard battery of tests administered in the assessment of sex offenders was used to compare the two groups. The tests examine sexual history and preference, substance abuse, violence, personality, and neuropsychological impairment. Results showed that diabetics more often than controls complained of impotence and were nonresponders during phallometric testing. Diabetics, as adults, tended to have less sexual experience with adults and more with pubescent females. The two groups did not differ in number of sexual or nonsexual offenses. The diabetics reported more problems controlling their emotions and more often than controls presented in assessment with inappropriate and/or aggressive behavior and poor cooperation. MMPI results showed diabetics to have more overall clinical disturbance than controls including anxiety, health concerns, family problems, authority problems, criminality, confused thinking and ruminating. Diabetics and controls did not differ in reported frequency of violent behavior but the diabetics responded more extremely, given the circumstances. Diabetics tended to show more violence to their own children. The role of diabetes in the relapse cycle model of offending is discussed.     

Outcome Following Bariatric Surgery in Super versus Morbidly Obese Patients: Does Weight Matter?

Background: Numerous investigators have attempted to identify prognostic indicators for successful outcome following bariatric surgery. The purpose of this study was to determine whether degree of obesity affects outcome in super obese [>225% ideal body weight (IBW)] versus morbidly obese patients (160-225% IBW) undergoing gastric restrictive/bypass procedures. Methods: Since 1984, 157 patients underwent either gastric bypass or vertical banded gastroplasty. Super obese (78) and morbidly obese (79) patients were followed prospectively, documenting outcome and complications. Results: Super obese patients reached maximum weight loss 3 years following bariatric surgery, exhibiting a decrease in body mass index (BMI) from 61 to 39 kg/m² and an average loss of 42% excess body weight (EBW). Morbidly obese patients had a decrease in BMI from 44 to 31 kg/m² and carried 39% EBW at 1 year. After their respective nadirs, each group began to regain the lost weight with the super obese exhibiting a current BMI of 45 kg/m² (61% EBW) versus 34 kg/m² (52% EBW) in the morbidly obese at 72 months cumulative follow-up. Currently, loss of 50% or more of EBW occurred in 53% of super obese patients versus 72% of morbidly obese (P < 0.01). Twenty-six percent of super obese patients returned to within 50% of ideal body weight (IBW) while 71% of morbidly obese were able to reach this goal (P < 0.01). Co-morbidities and complications related to surgery were similar in each group. Conclusions: Super obese patients have a greater absolute weight loss after bariatric surgery than do morbidly obese patients. Using commonly utilized measures of success based on weight, morbidly obese patients tend to have better outcomes following bariatric surgery.     

Social-Emotional Predictors of Preschoolers'' Responses to Adult Negative Emotion

The study examined predictors of children's prosocial responses to adult negative emotions. An adult displayed anger, sadness and pain during play sessions with 39 preschoolers (mean age = 43 months). Older children responded more prosocially to all three emotions, whereas children with greater emotion knowledge responded more prosocially to the adult's sadness. Children who behaved prosocially in response to peers' negative emotions also were prosocial after the adult's negative emotions, even with effects of age and emotion knowledge held constant. Assertive children responded more prosocially to the adult's anger, even with effects of other variables held constant. Both theoretical and practical implications are discussed.     

Computers in the Kindergarten

The computer use of two classrooms of kindergarten aged children in private school in Chicago were compared for variance in terms of the age and sex of the children, for variance by classroom, and for variance in the software selected. The major statistical method used was analysis of variance. There were two dependent variables: total frequency of computer use and the difference between the frequency in the first half and that in the second half (in order to examine the changing pattern of computer use in the two classrooms). There was no significant difference in computer use by sex or age, but there was a significant difference in the frequency of computer by classroom in the second half of the project compared to the first half. There was no significant difference in the software selected.     

MOBILITY AIDS FOR CHILDREN WITH HIGH-LEVEL MYELOMENINGOCELE: PARAPODIUM VERSUS WHEELCHAIR

The optimal method for providing mobility for children with myelomeningocele remains controversial. 39 children using a parapodium were compared with 29 children in wheelchairs. There were no significant differences between the two groups for medical complications, use of health-care services or activities of daily living, although there were differences in the patterns of complications. Children using the parapodium were more likely to develop lesions of the lower extremities, to have dislocated hips, to be more obese and to watch more television; children using wheelchairs were more likely to develop lesions of the gluteal region, to have knee-flexion contractures and to have fewer fecal accidents. The parapodium was judged by families to be less effective as a mobility aid; however, the upright posture it allows was considered extremely advantageous. A combined approach allowing upright posture and wheeled mobility would appear to be optimal.
