[The diagnostic value of selective lumbar nerve root block].

In patients with a neurogenic claudication syndrome root tension signs and neurological deficits are usually not observed. Lumbar myelography and CT scanning show also in a number of asymptomatic elderly people signs of nerve-root involvement. When stenosis of the vertebral canal is excluded the correlation in patients between symptoms and radiological signs is not clear. To improve the diagnostic ability selective lumbar root sheath infiltration was introduced by MacNab. The diagnostic value of this test was assessed prospectively. In 24 patients with a classic disk protrusion syndrome the sensitivity was 100%. The predictive value in patients with nerve-root-entrapment due to degenerative narrowing of the nerve-root was 70-80%.

[The value of nuclear magnetic resonance tomography in diseases of the knee joint].

In a prospective study we examined 107 patients suffering from an acute trauma or a chronic disease of the knee joint by MRI. The MRI results were compared to the results of arthroscopy. Normal anatomical structures can be differentiated and there is a high diagnostic reliability for lesions of the medial (accuracy: 91%, predictive value: 84%) and lateral (accuracy: 93%, predictive value: 79%) meniscus, complete tears of the anterior cruciate ligament (accuracy: 93%, predictive value: 75%), chondropathia of the patella, and osteochondritis dissecans. Partial ruptures of the ACL as well as small cartilage defects could usually not be demonstrated.

Stress fracture of the patella.

Stress fractures are rarely an indication for surgical treatment. In our case we decided to operate on the patient because of distraction of the fragments. Solid bony healing took longer than in traumatic fractures, but the good functional result confirmed our regimen.

A survey of oral biopsies in Brazilian pediatric patients.

This paper presents a review of 1018 oral biopsies in pediatric patients from the Oral Pathology Service, Minas Gerais Federal University, Brazil. The lesions were divided into ten main categories. The most common oral lesions in this study were follicular cyst in the maxillary anterior region, followed by inflammatory fibrous hyperplasia in the same region, and mucocele in the lower lip. Cysts of the jaws and oral soft tissues comprised 26.1 percent of total oral biopsies. The importance of these findings in oral diagnosis is discussed.
