A case of diffuse osseous tuberculosis with changes on skeletal Tc-99m methylene diphosphonate (MDP) and indium-111 chloride scintigraphy is presented. Only two other cases of bone scan findings in osseous tuberculosis (TB) were reported in the literature and both show patterns similar to diffuse metastatic disease. In addition, the demonstration of corresponding areas of decreased tracer activity on indium-111 bone marrow scintigraphy is a finding that has not been previously reported for skeletal tuberculosis.

Ionizing radiations have been shown to be carcinogenic to man as well as experimental animals. Malignancies following therapeutic radiation occur rarely. Over the past 10 years the authors recorded 10 cases of tumours in irradiated tissues. 3 occurred in patients irradiated for nasopharyngeal carcinoma, 3 were irradiated for tuberculosis adenitis, 2 for carcinoma of the cervix, 1 for carcinoma of the breast and 1 for basal cell carcinoma. The latent period for tumour induction following the irradiation varied from 5 years to 31 years. All these cases showed no evidence of recurrence or metastases of the original primary lesion; and the histology of the second primary differed from the first. Evidence of radiation damage was seen in all cases except for 2 patients who were treated for tuberculosis adenitis. The doses received varied from 900r to about, 9000r. Among the tumours produced, there were 3 cases of squamous cell carcinoma of the oral & postcricoid region, 2 cases of papillary carcinoma of the thyroid, 2 cases of adenocarcinoma of the rectum, 1 case of adenocarcinoma of the ethmoid, 1 case of osteosarcoma of the mandible and 1 case of extraskeletal osteosarcoma. The clinical features of these cases are discussed and other cases reported in the literature are reviewed.

Intracranial tuberculomas have become uncommon in industrial nations, while they still have a high incidence in underdeveloped countries. Four cases of intracerebral supratentorial tuberculomas are reported in this paper. Clinical findings suggestive of tuberculosis were present in only one case. The other cases were thought to be gliomas or metastases and the diagnosis was made only after surgery. The CT scan provided a good image of the lesions whose characteristics, however, were diagnostically confusing. When a tuberculoma is suspected, medical therapy alone should be administered initially. Surgery should be resorted to in cases of markedly increased intracranial pressure.

A 62-year-old man, who complained of gross hematuria, was admitted because of a space occupying lesion of the right kidney and left non-visualizing kidney on IVP. The right pyelogram was compressed laterally, and the left pyelogram showed a moth-eaten appearance of the middle and lower calyces which was consistent with tuberculosis. Abdominal aortography revealed a hyperneovascularization over the middle and upper portions of the right kidney. CT-scan revealed a low density area of the right kidney and left atrophic kidney. No distant metastases were disclosed by bone scanning, liver scanning, lymphangiographic and chest X-ray studies. Bilateral nephrectomy was performed because the right renal tumor occupied the main renal artery. Hemodialysis was started on the next day. Postoperative course was uneventful. Histological examinations of the surgical specimen revealed a right renal adenocarcinoma and left renal tuberculosis. We discuss the pathogenesis and treatment of the combination of renal tuberculosis and malignant tumor.

Arthroses of the acromioclavicular joint mainly occur after trauma and may be the cause of pain in the shoulder region which is difficult to treat. Other possible causes are metastases, hyperparathyroidism, tuberculosis and osteolysis whose pathogenetic mechanism is still unknown. If all conservative treatment methods have been tried without success, lateral resection of the clavicula, first described in 1941 by Gurd and Mumford, is the method of choice. Some of the results obtained by the present authors with 15 patients (of whom 11 were followed up) are presented and compared with those obtained by other authors. Since the results are altogether very good, this operation, which is technically simple to perform, is recommended for arthroses of the acromioclavicular joint of any etiology. In cases with Tossy III ruptures of the joint the procedure described by Weaver and Dunn can be performed in addition.

Apical caps, either unilateral or bilateral, are a common feature of advancing age and are usually the result of subpleural scarring unassociated with other diseases. Pancoast (superior sulcus) tumors are a well recognized cause of unilateral asymmetric apical density. Other lesions arising in the lung, pleura, or extrapleural space may produce unilateral or bilateral apical caps. These include: (1) inflammatory: tuberculosis and extrapleural abscesses extending from the neck; (2) post radiation fibrosis after mantle therapy for Hodgkin disease or supraclavicular radiation in the treatment of breast carcinoma; (3) neoplasm: lymphoma extending from the neck or mediastinum, superior sulcus bronchogenic carcinoma, and metastases; (4) traumatic: extrapleural dissection of blood from a ruptured aorta, fractures of the ribs or spine, or hemorrhage due to subclavian line placement; (5) vascular: coarctation of the aorta with dilated collaterals over the apex, fistula between the subclavian artery and vein; and (6) miscellaneous: mediastinal lipomatosis with subcostal fat extending over the apices.

Tumor mass negatively influences the outcome of surgery and radiotherapy by its influence on invasiveness and the propensity to metastasize before local treatment is applied. Tumor mass negatively affects the outcome of cancer chemotherapy in a manner quite different from the way in which it does surgery or radiotherapy. Cancer chemotherapy fails because cells develop resistance to anticancer drugs. Conceptually, there are two types of resistance both of which are mass related: temporary resistance (due to pharmacologic sanctuaries or altered cell kinetics) or permanent resistance (mutant lines developing specific and permanent resistance to one or more cancer drugs). Based on somatic mutation theory, it now appears that resistant mutants arise spontaneously early in the natural history of cancers, and the likelihood of a resistant line developing appears closely related to cell number, such that one or more resistant lines are likely present before most human malignancies become clinically evident. The development of permanent resistance more precisely accounts for the invariable inverse relationship between cell number and curability by drugs and the greater effectiveness of combination chemotherapy over single agents. New information on common pathways of drug resistance appear exploitable using tools available today or on the horizon. Treatment of bacterial infections, particularly tuberculosis, now truly appears to be a paradigm for cancer chemotherapy.

Eighteen patients with cardiac tamponade were treated by subxiphoid pericardiotomy performed with the patients under local anesthesia. This group included 9 cases of uremic pericarditis (50%), 5 cases of metastatic cancer (28%), 2 cases of trauma (11%), 1 case of tuberculosis (5.5%), and 1 case of unknown cause. Immediate relief from acute cardiac tamponade was obtained in all 18 cases with only minor and self-limiting postoperative complications, including transient supraventricular arrhythmias (five cases) and fever (five cases). There were no deaths related to either the operative procedure or reaccumulation of the pericardial effusion. The drainage period averaged 9.6 days (range, three to 28 days). Pericardial biopsy was performed in 15 of 18 cases. We conclude that subxiphoid pericardiotomy is a safe and effective method for the management of pericardial effusion of diverse causes. The ability to perform this technique safely using local anesthesia and the capacity to obtain a biopsy specimen under direct visualization make this technique superior to both needle pericardiocentesis and pericardiectomy in the acutely ill patient.

During the 37 year period between 1943 and 1980, 68 pediatric patients underwent 86 major pulmonary resections during 73 separate operations. The surgical procedures included lobectomy (55), segmentectomy (25), pneumonectomy (three), and cyst excision (three). The 73 operations were performed for nontuberculous infection, congenital malformation, tuberculosis, tumor, obstructive lung disease, cardiac-related problems, immunologic disease, and trauma in decreasing order of frequency. The operative mortality was 4.4%; the disease-relate late mortality was 6.2%, due to either chronic respiratory failure or metastatic disease. Complications occurred in 21.9% of the operations. Only one death occurred during the last two decades, but the morbidity rate remained constant through all decades. Analysis by decade showed a striking change in the spectrum of pediatric pulmonary operations over the 37 year study period. Three major trends were identified: (1) Bronchiectasis and tuberculosis, once the major indications for pulmonary resection, have, from a surgical standpoint, virtually disappeared. (2) Congenital pulmonary anomalies now account for the majority of major pediatric pulmonary resections. As a consequence, the patient age at operation has steadily decreased, and pulmonary resections in infants (under 1 year of age) make up almost half of the surgical resections currently being done. (3) Despite the marked decline in the number of operations performed for infectious pulmonary disease, the total number of pulmonary operations in the pediatric age group has not decreased.

Extrapulmonary tuberculosis generally develops from the lymphonodular part of the pulmonary primary complex by early or late haematogenous dissemination. Its manifestation depends especially on the time of latency of metastases. At present tuberculosis of the peripheral lymphnodes, the genitourinary system, the skin as well as the bones and joints are most frequently found in our area. They mainly develop from reactivation or late haematogenous dissemination in older patients.
