On the Limitations of Therapy Manuals

While the benefits of training manuals can hardly be questioned, they are exceedingly limited in reducing variability attributed to the "therapist factor." We propose that manuals provide a useful outline of the general principles of a therapeutic approach, but can only reduce therapist variability at the expense of other essential therapeutic phenomena. Manuals cannot adequately convey, for example, how the effective therapist functions as a model of adult living and as a person who provides guidance. We suggest that such an experience cannot readily be packaged in manualized form, though manuals may serve as a useful beginning. Recommendations for therapist manualized training include greater attention to the subtleties of human relationships and adequately conveying that any technique is effective only when catalysed by a living, relational process.

Skeletal abnormalities in the Apert syndrome

This paper reports on skeletal abnormalities in 38 patients with Apert syndrome. Analysis includes alterations in the shoulders, humeri, elbows, hips, knees, rib cage, and spine (except the cervical spine). Some patients had subacromial dimples and elbow dimples during infancy. Mobility at the glenohumeral joint was limited. Progressive limitation in abduction, forward flexion, and external rotation with growth was virtually a constant finding. The acromioclavicular joint was prominent and sometimes had an angular, pointed appearance clinically. This was often associated with atrophic musculature and winging of the scapulae. Limited elbow mobility was common and usually mild in degree. Decreased elbow extension was most often found with decreased flexion, pronation, and supination occurring less frequently. Limited elbow mobility did not change significantly with growth in contrast to the increasing severity observed in the shoulder joint. Short humeri were a constant finding beyond infancy and genua valga of mild degree were present in many cases. Radiographic examination strongly suggests that the Apert syndrome is characterized by a multiple epiphyseal dysplasia. We found delay in appearance of postnatal ossification centers, particularly in the humeral head, greater tuberosity, capitulum, and radial head. Subsequently, these bones became abnormal in shape. Glenoid dysplasia was observed consistently. The neck of the scapula was very short or absent and the inferior margin of the glenoid cavity was poorly demarcated from the infraglenoid tubercle. The humeral head became oblong in shape with relative prominence of the greater tuberosity which compromised abduction. In the elbow, the capitulum was often small and the radial head was flat in many instances. Subluxation or dislocation of the radial head or angulation of the radial neck was observed in some cases. In the hip joint of some adults, the femoral necks were short and broad with prominence of the greater trochanters. Less common radiographic findings are also discussed. © 1993 Wiley-Liss, Inc.     

Total lymphocyte count of 1200 is not a sensitive predictor of CD4 lymphocyte count among patients with HIV disease in Kampala, Uganda

Introduction

Total Lymphocyte Count (TLC) has been found to be an inexpensive and useful marker for staging disease, predicting progression to AIDS and death and monitoring response to ART. However, the correlation between TLC and CD4 has not been consistent. Access to HAART is expanding in Kampala, Uganda, yet there are no published data evaluating the utility of TLC as inexpensive surrogate marker of CD4 cell count to help guide therapeutic decisions.

Objective

To evaluate clinical illnesses and total lymphocyte count (TLC) as surrogate markers of the CD4 cell count in HIV infected persons being considered for ART.

Methods

A total of 131 patients were enrolled and evaluated by clinical assessment, TLC and CD4 count. Clinical illnesses and TLC dichotomized at various cut-point values were used to determine the sensitivity, specificity, and positive and negative predictive values (PPV and NPV) for the diagnosis of CD4 count <200 cells/mm³ among 100 participants fulfilling criteria for WHO clinical stage 2 and 3.

Results

A strong correlation was observed between TLC and CD4 (r = 0.73, p<0.0001). For all clinical syndromes, except pulmonary tuberculosis, the positive predictive values (PPV) for a CD4 count <200 cells/mm³ were high (>80%) but the negative predictive values (NPV) were low. Using the WHO recommended TLC cut-off of 1200 cells/mm³ to diagnose a CD4 less than 200 cells/mm³, the PPV was 100%, and the NPV was 32%.

Conclusion

Our data showed a good correlation between TLC and CD4 cell count. However, the WHO recommended TLC cutoff of 1200 did not identify the majority of WHO stage 2 and 3 patients with CD4 counts less than 200 cells/mm³. A more rational use of TLC counts is to treat all patients with WHO stage 2 and 3 who have a TLC <1200 and to limit CD4 counts to patients who are symptomatic but have TLC of >1200.

Blepharoptosis in association with ipsilateral adduction and elevation palsy A form of fascicular oculomotor palsy

A 16-year-old girl hospitalized with a sudden onset of blepharoptosis and diplopia revealed a combined paresis of the elevator palpebrae, the superior rectus, and the medial rectus muscles of the left eye as quantitatively demonstrated by the Hess chart and levator action test. A small midbrain lesion confined to the left cerebral peduncle and tegmentum, presumably by an ischemic or demyelinative process, was identified on magnetic resonance imaging. Despite uncertainty in its pathology, the incomplete oculomotor palsy of this case is certainly a consequence of oculomotor fascicular involvement in the intra-axial nerve root which initially fans out and then converges into the peripheral compact bundle. We speculate on the revised version of the oculomotor fascicular arrangements by which the neurophthalmologic features of the current case are better explained.     

Serum cortisol level and disc displacement disorders of the temporomandibular joint

Temporomandibular disorders (TMD) are a significant public health problem, affecting approximately 5–12% of the population. Objectives: This retrospective cross‐sectional study investigated the relationship between 8 AM serum cortisol levels (8ASC) and disc displacement disorders (DDD) of TMD. One hundred and forty patients with DDD were recruited. Among them, 60 patients comprised the case group of disc displacement without reduction with limited opening (DDWORWLO, age 37·7 ± 17·22), and 80 were ‘other DDD’ for the control group (age 36·4 ± 13·08). The independent variables included domains of demography, history, malocclusion, comorbid symptoms, comorbid TMD and 8ASC. Data were analysed with the chi‐square test, logistic regression and receiver operating characteristic (ROC) curve. Results of multiple logistic regression showed that 8ASC was the only factor significantly related to DDWORWLO (P = 0·006). Receiver operating characteristic analysis of DDWORWLO and 8ASC indicated an area under the curve of 0·669, standard error of 0·049 and P value of 0·001. The adequate cut‐off point of 8ASC was 12·45 (μg dL^?1), with sensitivity of 0·636, and specificity of 0·729. 8 AM serum cortisol level can be used as a clinical clue to differentiate DDWORWLO from other DDD.     

Limited Wegener’s Granulomatosis Presenting with an Isolated Abduction Deficit

Wegener’s granulomatosis often affects the orbit, typically presenting with painful proptosis. The authors describe a 14 year-old girl, with limited Wegener’s granulomatosis, who initially presented with an isolated painless abduction deficit that spontaneously resolved over several weeks. She subsequently developed painful proptosis and diplopia, followed by facial and oral nodules. This case demonstrates that limited Wegener’s granulomatosis can rarely present with an isolated painless abduction deficit.
