[EX Q]: Abstract: Recognizing that not all patients with low back pain have lumbar disc disease, the authors began to inject facet joints in June 1982 and have experience now with 21 patients, each injected under fluoroscopic control with a mixture of local anesthetic and steroid. One technical problem occurred when large osteophytes blocked access to the facet joints. Otherwise, there were no complications and minimal morbidity. Most patients (15 of 20; 75%) had an initial response, but a much smaller number (six of 18 followed more than three months; 33%) had a lasting response. Repeat injections, when done, always led to temporary improvement but rarely to lasting relief (one of five; 20%). Three factors characterized the patients: a negative screening examination for other causes of back pain or sciatica; back pain with tenderness localized over one or more facet joints; and radiologic changes of degenerative joint disease within the facet joints. Facet joint disease may be a significant cause of low back pain. The above three criteria are useful in clinical identification of patients with this problem. Facet joint injections play an important role in the diagnosis and treatment of low back pain.

[EX Q]: Abstract: The amount and sources of T3 associated with high affinity, low capacity cellular nuclear receptors in brown adipose tissue (BAT) have been estimated by in vivo pulse-labeling techniques. Maximal binding capacity was measured by in vivo saturation analysis. Nuclear receptor occupancy at endogenous levels of T3 and T4 in euthyroid rats was estimated from the equilibrium nuclear to serum ratio of tracer T3, and the locally generated nuclear T3 to serum T4 ratio after injecting tracer T3 and T4. These ratios were multiplied, respectively, by the endogenous concentrations of T3 and T4 as measured by RIA. The maximal binding capacity was 0.65 ng T3/mg DNA, and saturation was 71%. Fifty-five percent of the nuclear T3 was generated locally, and 45% was derived from circulating T3. BAT is, hence, comparable to the liver in number of receptors (approximately 5000/cell) and to the pituitary with regard to saturation and relative contributions of locally generated T3 and plasma T3 to nuclear T3. These results suggest that BAT may be an important target for thyroid hormones and, along with other data, that alterations in the activity of the type II 5'-deiodinase of this tissue may influence the saturation of nuclear T3 receptors.

[EX Q]: Abstract: Traditional therapy for malignant pleural effusions includes thoracentesis or tube drainage with instillation of irritants to achieve pleurodesis. This can require a lengthy hospitalization, causes pain and discomfort, and has an appreciable failure rate. Because of these drawbacks, the authors used a shunting device to transfer fluid to the peritoneal cavity in 17 patients with malignant pleural effusions. Eleven patients had undergone previous therapeutic thoracenteses and three had chest tube placement with failed sclerosis. The shunt was a subcutaneous valved pump chamber with attached pleural and peritoneal catheters, which used manual compression to transfer fluid against the normal abdominal/pleural pressure gradient. Operative placement under local or general anesthesia was performed without complication. Five patients achieved minimal benefit, either because of moribund status or their inability to compress the pump effectively. In the other 12 patients, there was radiographic evidence of diminished or stabilized pleural effusion; respiratory symptoms were effectively palliated, and no further treatment for their effusion was required. Peritoneal dissemination of malignant cells has not been clinically detected. We feel that pleuroperitoneal shunting is a valid new method for treatment of malignant pleural effusions which can effectively palliate respiratory symptoms with low morbidity. Advantages include the absence of external tubing and the possibility for only a short hospitalization or even outpatient placement. Shunting is applicable for patients who are able to perform the requisite pumping and is particularly suitable for those with trapped lungs or who have failed attempted pleural sclerosis.
