Ear examination

Adolescent idiopathic scoliosis is the single most common form of spinal deformity seen in orthopedic practice. Our knowledge about the epidemiology, etiology, natural history, and treatment has recently increased dramatically. The incidence of small curves is rather high (2% of the population), whereas severe curves are much less common (<0.1%), but we cannot always predict which curve will progress. Abnormalities of the neuromuscular system and of calcium metabolism, and certain growth, genetic, and mechanical factors may all play roles in the pathogenesis of the disorder. The physiologic secondary effects of severe scoliosis relate to restrictive lung disease, but most patients do not have a deformity great enough to affect their cardiorespiratory function. The psychological and social effects of scoliosis are significant for patients but difficult to quantitate. For most patients with moderate scoliosis—that is, more than 25 to 30 degrees—treatment with an underarm brace or electrical stimulation is adequate to “control” progression of the curve. Surgical fusion allows actual correction of the curve but is indicated in only a small percentage of patients—usually those with more than 50 degrees of deformity.     

Clinical examination of sheep

Clinical examination of sheep involves the interpretation of information about both the individual and the flock within the context of the farm environment. It is an art, which relies on careful observation and the systematic collection of specific data, suggestions of which are presented in tabular format. However, interpretation is subjective with the potential for wide variation between clinicians. To ensure that the information is directly transferable, clinicians have a responsibility to use repeatable measurements and assessments wherever possible. Standard scoring systems and criteria that have been developed primarily for use in the research environment are reviewed and their relevance to the clinician is discussed. In particular, the repeatability of measures is considered.     

Peripheral in-continuity tissue examination

When treating skin cancers, it is essential to remove the entire neoplasm if possible. Immediate reconstruction is most helpful in returning the patient to a useful and satisfactory life. The Mohs histologic technique can be time-consuming and cumbersome. Reconstruction can be delayed. A modification of Mohs technique, peripheral in-continuity tissue examination (PITE), is described in which the surgeon and the pathologist combine their talents to remove the tumor. All margins are evaluated, and the surgical defect is closed primarily. Larger and more complex tumors can be removed and defects immediately reconstructed using this efficient technique, obviating the inconvenience, pain, and expense of multiple, separate procedures.
