Changes in patients with gender-identity problems after parental death.

The authors studied the incidence of parental loss among 163 gender-disordered patients and an equal number of psychiatric control patients. An unusually high number of gender-disordered patients had lost their fathers, particularly during adolescence and early adulthood. Many of these patients showed shifts in gender identity in the year after loss, and during that period many requested surgical sex reassignment for the first time. Changes in the patient's relationship with the remaining parent and experiences related to loss of the father are discussed.

A meta-analysis of the efficacy of non-operative treatments for idiopathic scoliosis.

With use of data culled from twenty studies, members of the Prevalence and Natural History Committee of the Scoliosis Research Society conducted a meta-analysis of 1910 patients who had been managed with bracing (1459 patients), lateral electrical surface stimulation (322 patients), or observation (129 patients) because of idiopathic scoliosis. Three variables - the type of treatment, the level of maturity, and the criterion for failure - were analyzed to determine which had the greatest impact on the outcome. We also examined the effect of the type of brace that was used and the duration of bracing on the success of treatment. The number of failures of treatment in each study was determined by calculating the total number of patients who had unacceptable progression of the curve (as defined in the study), who could not comply with or tolerate treatment, or who had an operation. The percentage of patients who completed a given course of treatment without failure, adjusted for the sample sizes of the studies in which that treatment was used, yielded the weighted mean proportion of success for that treatment. The weighted mean proportion of success was 0.39 for lateral electrical surface stimulation, 0.49 for observation only, 0.60 for bracing for eight hours per day, 0.62 for bracing for sixteen hours per day, and 0.93 for bracing for twenty-three hours per day. The twenty-three-hour regimens were significantly more successful than any other treatment (p < 0.0001). The difference between the eight and sixteen-hour regimens was not significant, with the numbers available. Although lateral electrical surface stimulation was associated with a lower weighted mean proportion of success than observation only, the difference was not significant, with the numbers available. This meta-analysis demonstrates the effectiveness of bracing for the treatment of idiopathic scoliosis. The weighted mean proportion of success for the six types of braces included in this review was 0.92, with the highest proportion (0.99) achieved with the Milwaukee brace. We found that use of the Milwaukee brace or another thoracolumbosacral orthosis for twenty-three hours per day effectively halted progression of the curve. Bracing for eight or sixteen hours per day was found to be significantly less effective than bracing for twenty-three hours per day (p < 0.0001).

Adding a choice-based program for tobacco smoking to an abstinence-based addiction treatment program.

A smoking program that provides awareness education about smoking to all chemical dependency (CD) clients and staff, while allowing treatment for smoking to be optional, was developed at an abstinence-based addiction treatment center. This study measured the effects of introducing this mixed model for treatment of smoking and other substances on clients and staff. Attitude and program utilization data were collected, and CD clients were followed-up. The value of offering a smoking program during CD treatment and of framing it within a choice-based philosophy was strongly endorsed by staff and CD clients. Smoking program CD clients did not report major problems with other clients continuing to smoke. Most (55.6%) of the staff who smoked (n = 18) entered the smoking program during the first year of implementation; 38.0% of CD clients who smoked (n = 424) actively joined the smoking program; and of CD clients who chose cessation, 17.5% were abstinent at follow-up.

Factorial validity and reliability of the Devereux Elementary School Behavior Rating Scale.

The factorial validity and internal consistency reliability of the Devereux Elementary School Behavior Rating Scale was examined using a random sample of elementary-school children in grades 1 through 6. Teacher ratings of subjects' classroom behaviors on the Devereux approximated ratings obtained by the standardization sample. Internal consistency (coefficient alpha) reliability coefficients of the 11 Devereux subscales were found to be quite adequate, ranging form .80 to .93. Intercorrelations among Devereux subscales were moderate to high. A principal factor analysis of the 11 subscales produced two factors with eigenvalues greater than 1.0. which cumulatively accounted for 70.2% of the total variance. When rotated via an orthogonal (Varimax) solution, the two resultant factors appeared to measure "emotional adjustment" and "academic related" dimensions of classroom behavior. Given the problem of multicollinearity that was shown to exist among subscales, the authors suggest caution in the interpretation of Devereux subscales as discrete factors.

Female-to-male transsexuals and their partners.

This paper reviews briefly the literature on gender disorders, that is transsexualism in females. Forty-one female-to-male transsexuals and twenty-one female partners of these patients were evaluated in the Gender Identity Clinic at the Clarke Institute of Psychiatry. The authors report on the type of behaviour patterns with particular reference to the kind of relationship the patients form with their partners. These seem to be stable, long-term relationships, though both the transsexual and his partner have had considerable sexual experience prior to forming this relationship. Contrary to what other workers report, these transsexuals wish to parent children and indeed frequently chose partners who already had children. The authors speculate on the reasons why a normal biological female would choose a "penis-less man" as a partner and form a long-term enduring relationship with him.

The roentgenographic appearance of the "corrected clubfoot".

Roentgenographic changes associated with a corrected clubfoot may not be readily apparent. In some individuals with minimal residual deformity, these roentgenographic changes are quite subtle. The roentgenographic abnormalities of the corrected clubfoot are described.

Scleroderma of the foot: orthopaedic treatment.

Four patients with scleroderma involving the feet have been treated at Childrens Hospital of Los Angeles by the authors. All children had severe deformity of the feet secondary to the scleroderma. A review of the literature reveals little past mention of indications or treatments of this deformity in the past with the exception of the use of local steroids. Six feet in four children underwent orthopedic treatment. Treatment was primarily by casting to stretch soft tissues and gain as much correction as possible. Surgical correction of the remaining deformity by releasing the soft tissue contractures was then accomplished. Internal fixation of the foot in the corrected position was carried out in four cases. Three of the four patients showed significant improvement following soft tissue surgery and one patient was unchanged. Surgical treatment of the patient with scleroderma can be carried out safely as long as careful attention is paid to circulatory status and extensive preoperative casting and stretching of "soft" tissues is utilized.

Percutaneous reduction of displaced radial neck fractures in children.

Various techniques have been used for reduction of displaced radial neck fractures in children. Eighteen children with displaced radial neck fractures were treated by percutaneous reduction with a Steinmann pin after failing closed reduction. Reduction was successfully accomplished for 15 patients. The three patients failing percutaneous pin reduction had comminuted radial head and neck fractures (two patients) or a completely rotated and displaced radial head (one patient). Percutaneous pin reduction of angulated and displaced radial neck fractures is a simple, safe alternative to open reduction.

Fournier's gangrene of the penis.

Fournier's gangrene is a rare, fulminant, though generally localizaed disease of the scrotum and penis. Three cases are presented in which the sexual practices of the patients may have played a role in the etiology. Hospitalization, parenteral antibiotics, and appropriate surgical treatment are required.

Results of 21 Wagner limb lengthenings in 20 patients.

Roentgenograms and charts were reviewed on 20 patients (average age: 13.2 years) who had 21 Wagner limb lengthenings since 1975. Lengthenings included 15 femora (six acquired, eight congenital, and one fibrous dysplasia), four tibiae, and two humeri (one acquired and one congenital). Average femoral lengthening was 6.6 cm; tibial, 5.9 cm; and humeral, 9.7 cm. Lengthening of femora with congenital shortening (6.5 cm) was nearly the same as femora with acquired shortening (6.8 cm), and 85% of all lengthenings were greater than 5 cm. Humeri were lengthened more than 50%. Seventy-two percent of patients were in the 50th percentile or less of stature; 61% were in the 15th percentile or less of stature. Seventy-five percent had complications, with 65% having more than one major complication: pin tract and superficial infections in 40%; deep infections in 20%. All infections were in femoral lengthenings. Nonunion occurred in two patients (10%), and fracture after plate removal in two patients (10%). Five patients (25%) had nerve palsies, and four of these resolved without treatment. Malunion rate was 20%. Five patients developed joint contractures. Complications did not correlate with amount of lengthening but congenital deformities had a higher incidence of complication. Eleven patients required 19 additional procedures necessitated by the lengthening procedure. Wagner leg lengthening is generally recommended when amputation is only other surgical alternative and a full, complete informed consent is given to the parents and patient.

Observer variation and relationship of computed tomography to severity of beryllium disease.

Although high resolution computed tomography (HRCT) is commonly used to assess interstitial lung disease (ILD), relatively little is known about interrater reliability and construct validity of HRCT-reported nodules, ground-glass opacity, or other typical findings. We determined the interobserver and intraobserver variability of HRCT findings and correlated HRCT abnormalities with physiologic measures in 57 patients with chronic beryllium disease (CBD). Reliability of HRCT scan measurements were assessed using weighted kappa (K(W)) and intraclass correlation coefficients. We correlated HRCT with spirometry, body plethysmographic lung volumes, diffusing capacity for carbon monoxide (DL(CO)), maximal exercise testing with measurement of arterial blood gases, and bronchoalveolar lavage (BAL). Interobserver agreement for three of the HRCT abnormalities found in CBD was moderate: the K(W) for nodules, septal lines, and ground-glass attenuation were 0.53, 0.44, and 0.53, respectively. Agreement was poor for bronchial wall thickening (K(W) = 0.15). HRCT scores correlated significantly with DL(CO), gas exchange at rest and at maximal exercise, and lung volume. This study demonstrates that HRCT has good interrater reliability and correlates with indices of the severity of granulomatous lung diseases such as CBD.

Reassessment of conservative management for stage T1N0M0 transitional cell carcinoma of the bladder.

PURPOSE: We evaluated the outcome of stage T1 transitional cell carcinoma of the bladder treated with local tumor resection and intravesical therapies. MATERIALS AND METHODS: Of 42 patients with stage T1 bladder cancer seen at our clinic during a 10-year period 38 were treated conservatively with local tumor resection, intravesical therapy and long-term followup. Bacillus Calmette-Guerin (BCG) was used as the primary intravesical agent since 1986. RESULTS: Of the 38 patients 15 had initial grade 2 or 2 to 3 tumors, including 9 (60%) who had at least 1 or more local recurrences but without disease progression. The remaining 23 patients had grade 3 or grades 3 to 4 stage T1 tumors, with local recurrence in 17 (74%) and disease progression in 8 (35%). Furthermore, 5 patients (22%) died of the metastasis despite salvage therapies. CONCLUSIONS: For patients with initial grade 2 or grades 2 to 3, stage T1 disease the risk of disease progression is low. Current management with local tumor resection and intravesical BCG is appropriate and should be continued. Patients with high grade, stage T1 disease are at particularly high risk for disease progression and BCG does not seem to decrease this risk effectively. Therefore, immediate cystectomy is appropriate and should be recommended.

How common are renal angiomyolipomas in patients with pulmonary lymphangiomyomatosis?

Pulmonary lymphangiomyomatosis has been associated with renal angiomyolipoma in case reports, but the prevalence of this association has not been well documented. The objective of this study was to determine the frequency of renal angiomyolipoma in a series of subjects with pulmonary lymphangiomyomatosis. Eighteen consecutive patients with pulmonary lymphangiomyomatosis were seen at a single institution between 1989 and 1994. Of these, one patient was excluded because she did not have an abdominal computed tomographic (CT) scan. We found eight out of 17 (47%) patients with pulmonary lymphangiomyomatosis to have renal angiomyolipomas. These were found either at surgery or on abdominal CT scanning. Thus, renal angiomyolipomas occur commonly in association with pulmonary lymphangiomyomatosis. Consequently, the early detection of renal angiomyolipoma by abdominal CT may be important, because lesions with dimensions larger than 4 cm may present an increased risk for complications related to tumor growth or hemorrhage. Serial follow-up by ultrasonography or CT scanning is important in identifying and monitoring high-risk patients. Prophylactic treatment (partial or total nephrectomy) may be considered for patients with tumors that show significant growth or other complications, such as hemorrhage.

Thoracic aortic injury: how predictive is mechanism and is chest computed tomography a reliable screening tool? A prospective study of 1,561 patients.

BACKGROUND: Thoracic aortic injury (TAI) is a devastating condition in which prompt recognition can obviate morbidity and mortality. It is a long-held belief that TAI is more likely when there is a "major mechanism of injury." The purposes of this prospective study were to determine mechanism characteristics that are predictive of TAI and to evaluate chest computed tomography (CT) as a screening tool for TAI. METHODS: Over a 5 1/2 year period, blunt chest trauma patients at two Level I trauma centers were evaluated for potential TAI. Patients were assigned mechanism and radiograph scores from 1 (low suspicion for TAI) to 5 (very high suspicion for TAI). Immediate aortography was obtained when suspicion for TAI was very high. The remaining patients were evaluated with contrast-enhanced chest CT. Confirmatory aortography was obtained on all positive chest CT scans and on all patients with mechanism scores of 4 or 5 even if the CT was negative. Mechanism and radiographic data were correlated with the results of aortic imaging. RESULTS: Of the 1,561 patients evaluated for TAI, 30 aortic injuries were found. The assessment of mechanism was imperfect with a reliance on often incomplete and subjective data. The subjective mechanism score proved to be the most useful predictor of TAI. Radiographic scores were useful but insensitive for intimal injuries. Computed tomography was found to have 100% and 100% NPV for TAI. CONCLUSION: Considering the inherent difficulties in identifying patients at risk for TAI and the effectiveness of chest CT as a screening tool for aortic injury, we recommend liberal use of chest CT in blunt chest trauma. Guidelines for determining the need for aortic imaging are outlined.

Can chest CT be used to exclude aortic injury?

PURPOSE: To determine whether chest computed tomography (CT) can be used to exclude aortic injury. MATERIALS AND METHODS: Patients in whom there was very high suspicion of traumatic aortic injury were examined with aortography only. Other patients were examined with contrast material-enhanced CT. Follow-up aortography was performed in all patients with moderate to high suspicion of traumatic aortic injury and in all patients with CT scans that were positive for traumatic aortic injury. CT scans were regarded as positive when they showed mediastinal hematoma or direct findings of aortic injury. During a 4 1/2-year period, 1,009 patients (263 female, 746 male; age range, 3-90 years) were evaluated for possible traumatic aortic injury. RESULTS: Of the 207 patients who underwent aortography directly without CT, 10 had traumatic aortic injury. Of the 802 patients who were examined with CT, 382 underwent follow-up aortography. In this group, there were 10 true-positive and no false-negative CT scans. CT had 100% sensitivity and a 100% negative predictive value for the detection of traumatic aortic injury.
