Peripheral nerve stimulating devices were implanted for pain control in 33 patients with a variety of disabling chronic pain conditions, which had persisted despite usual medical and surgical therapy. The implants were placed on major nerves innervating the area of the patient's pain. Records were obtained of each patient's stated relief from pain produced by nerve stimulation, along with assessments of narcotic withdrawal, ability to return to work, sleep pattern, and relief from depression. Based on these five criteria 17 patients were judged to be treatment failures, while eight patients had excellent results, and seven had intermediate results. Twelve of the failures were in patients with either low back pain with sciatica, or pain from metastatic disease. The most dramatic successes occurred in patients with peripheral nerve trauma. The incidence of complications has been low, and two patients have used the stimulator for 5 years without adverse effects. Techniques of peripheral stimulator implantation, possible mechanisms of action, and conclusions regarding peripheral nerve stimulation in the treatment of chronic pain are discussed.

We describe a patient with sacral insufficiency fractures presenting as acute onset low back pain without antecedent trauma. Sacral insufficiency fractures are an often unsuspected cause of low back pain. The clinical presentation and plain radiograph findings can mimic metastatic disease, leading to unnecessary investigations and treatment. However, the location, linearity, and appearance of these fractures on computed tomography is very characteristic and obviates the need for further evaluation.

Metastatic disease of the lumbar spine is a relatively common, but catastrophic cause of low back pain. Because of an increasing role as primary care providers for back pain patients, it is essential that chiropractors keep this possibility in mind. Careful consideration of the patient's history, physical and laboratory findings, and the use of imaging procedures are helpful in establishing a correct diagnosis in those cases where metastasis is suspected.

Insufficiency fractures of the sacrum are a commonly recognized form of stress fracture typically occurring in elderly patients. As such patients usually present with low back pain, MR imaging is often performed initially as a means of evaluation. We present 5 patients with sacral insufficiency fractures imaged with MR. Metastatic disease was a leading clinical suspicion as all patients were elderly and three had known primary neoplasms. T1-weighted sequences demonstrated bands of decreased signal intensity, usually paralleling the sacral aspect of the sacroiliac joints and occasionally occurring as a horizontal band across the sacral body. Four of five patients underwent further evaluation with computed tomography (CT) or nuclear bone scanning, which confirmed the diagnosis of sacral insufficiency fracture. We conclude that MRI is sensitive but not specific in detecting sacral insufficiency fractures. As MR imaging is rapidly becoming the method of choice for evaluating back pain, it is important to consider this diagnosis in elderly persons.

The first case of carcinosarcoma originating from the renal pelvis in Japan is reported. A fifty-five year old woman was admitted to the hospital on July 13, 1987, complaining of a one-year history of lumbago. On physical examination, a mass of child's head size was palpable in the right loin. There were other palpable masses in the posterior head (8 x 8 cm), left anterior chest (3 x 3 cm) and sacral region (3 x 3 cm). A chest X-ray showed multiple pulmonary metastases and an excretory urogram revealed a non-visualizing right kidney. Computed tomogram and renal angiogram suggested right renal tumor. Right renal arterial embolization with ethanol sclerosing was performed. She had previously undergone biopsy of the sacral lesion at another hospital, histological examinations of which pointed to suspected carcinosarcoma. She was treated by a combination chemotherapy with vincristine, adriamycin and cyclophosphamide. Despite one course of chemotherapy, her general condition deteriorated with progression of metastatic lesions in the regions other than the lungs. She died of the disease on december 9, 1987. Autopsy was performed. Sections of the right kidney showed a transitional cell carcinoma in-situ with squamous and glandular differentiation in addition to the chondrosarcoma. The metastases were found in the liver, lung and bone, all of which consisted of chondrosarcoma. On the other hand skin metastases consisted of both carcinomatous and sarcomatous elements. The pathological specimens were reviewed at the Armed Forces Institute of Pathology, Washington, D.C.

An autopsy case report of leiomyosarcoma of the thoracic aorta is presented. The patient was a 75-year-old Japanese woman who complained of hypertension, melena and lumbago. The autopsy revealed severe occlusion of the thoracic aorta due to the tumor. Histologically the tumor consisted of fascicular proliferation of atypical fusiform cells. Metastases were seen in the bilateral adrenal glands, pancreatic tail and bones (vertebrae and femur). At the distal portion of the aortic tumor, there was a secondary dissecting aneurysm.

This phase 1-2 trial investigated the use of a 100% wt/vol emulsion of perfluorooctylbromide (PFOB) in computed tomography (CT) of 30 patients with metastatic cancer. Injection of 3 g/kg (maximum dose administered to these patients) provided an average liver enhancement of +31 HU on CT scans obtained after 48 hours. Maximum splenic opacification occurred immediately after injection; 1 g/kg, which allowed an immediate enhancement of +35 HU, appeared sufficient for the diagnosis of splenic conditions. Vascular opacification was insufficient for diagnostic purposes. In four patients with metastases, more lesions were seen with the use of PFOB with CT than with conventional CT. Adverse effects included five cases of low back pain that were reversible when the infusion rate was reduced. Fever and trembling were also noted 6 hours after injection in five patients. In all patients, symptoms regressed spontaneously within several hours. Clinically inapparent and dose-independent splenomegaly (volume increase of at least 20% on CT examinations) was noted in eight patients.

About 130 Norwegian men (15-45 years old) develop testicular cancer each year. Men with a history of undescended testes, atrophic testes and/or fertility problems probably represent a high risk group. Typical symptoms are tumour, harder consistency and discomfort in the testes, low back pain and gynecomastia. Testicular ultrasonography often helps to establish the correct diagnosis. Seminoma is separated from non-seminoma histologically. Adjuvant radiotherapy to the retroperitoneal lymph nodes is the most frequent treatment in seminoma patients with early disease and is combined with chemotherapy in patients with advanced disease. Chemotherapy and surgery are the main therapeutic modalities in non-seminoma patients. In clinical trials a "wait and see" policy is applicable in selected patients with non-seminoma without metastases, provided that frequent follow-up examinations are feasible. Gastrointestinal side effects, alopecia, peripheral neuropathy and azoospermia are the most frequent acute and reversible side effects of treatment of testicular cancer. Post-treatment paternity can be achieved by at least half of the patients who wish to father a child after treatment. The 5-years' survival rate for young patients with testicular cancer is 95%. Young men should perform testicular self-examination regularly. Medical officers in the Armed Forces and doctors at schools and universities and in occupational health should be aware of testicular cancer in young adults with suspicious clinical findings.

It is generally accepted that the metastases of intracranial glioma to extracranial location are rare. In such a case the minimal criteria proposed originally by Weiss should usually be satisfied if a report is to be considered as an acceptable case of metastasizing central nervous system glioma outside the central nervous system. We report a case of glioblastoma multiforme, fulfilling Weiss' criteria, metastasizing the spinal epidural space. The patient was a 32-year-old male, who underwent craniotomy and subtotal removal of a glioblastoma multiforme in the left parietooccipital area. He was additionally treated with irradiation and chemotherapeutic agents. Twelve months after the craniotomy, he was admitted again to our clinic because of sudden onset of severe lumbago, paraplegia and urinary disturbance. Diagnosis of a spinal epidural tumor was made and laminectomy (Th10-L1) was performed. At operation, an epidural mass was found, however no invasion to the spinal cord or dura was noted. Histological diagnosis of the tumor was glioblastoma multiforme. Although he was treated with radiation, pulmonary metastasis was manifested one month later, and the condition of the patient deteriorated. He died 21 months after the first operation and 8 months after the second operation. Even at the terminal stage, his consciousness was clear without any sign for recurrence of intracranial tumor. The general autopsy was done and multiple metastatic lesions of glioblastoma multiforme in paratracheal and paraaortic lymph node, left pleura, both lungs and spinal cord were observed. The present case suggests that the surgical intervention, irradiation, and chemotherapy may contribute to extracranial metastasis of a glioblastoma.

Renal cell carcinoma during pregnancy is extremely rare. This 30-year-old patient was first seen on Dec. 18, 1983 at the 7th week of her 2nd pregnancy. She had asymptomatic hematuria. Cystoscopy revealed normal findings and sonogram showed well defined echogenic mass in the upper pole of the right kidney. She was admitted to our hospital on account of gross hematuria and severe lumbago on Jan. 19, 1984. The pregnancy was stopped by artificial abortion. Renal angiography revealed a rich-vascularized tumor in the upper pole of the right kidney. Preoperatively, arterial embolization was done and nephrectomy was performed. Histological examination showed a well-differentiated adenocarcinoma. There was no involvement of the renal vein and no lymph-node metastases were found in the operation specimen. The post-operative course was uneventful. This rare case of renal cell carcinoma during pregnancy is herein reported along with some discussion.
