Between April 1986 and April 1989, each of 108 patients received an ileum neobladder, 94 patients for total bladder substitution after radical cysto-prostatectomy and 14 for augmentation of a fibrotic and contracted bladder following tuberculosis, interstitial cystitis or radiotherapy of the pelvis. The operative technique is standardized, relatively simple and safe, and it prevents upper urinary tract deterioration and reflux. Continence is preserved in more than 80% of all patients by the function of the external urethral sphincter and by the high capacity and the low internal pressure of the intestinal reservoir. Follow-up of more than 3 months postoperatively was possible in 96 patients, the evaluation including micturition behavior at home and a urodynamic investigation. Stress incontinence requiring correction by an artificial sphincter was found in 3 and nocturnal incontinence necessitating some external device in 6 patients. There was no perioperative mortality. Local tumor recurrence and/or metastases occurred in 14 patients; 7 patients died postoperatively, 5 owing to tumor progression, 1 of pneumonia and serve metabolic acidosis, and 1 owing to septicemia of unknown cause. Re-operation was necessary in 13 patients, in 6 because of mechanical ileus or intra-abdominal abscess, in 3 because of stenosis of the uretero-ileal anastomosis, in 1 because of tumor progression, in 1 because of vesico-vaginal fistula, in 1 patient because of incisional hernia, and in 1 because of wound dehiscence. Urethrotomy or dilatation of urethral strictures was necessary in 8 patients. All other early and late complications were rare and could be managed by conservative means.(ABSTRACT TRUNCATED AT 250 WORDS)

An analysis of 294 enlarged peripheral lymph node biopsies in Ife, Nigeria, revealed that the underlying disease in 51.7% was chronic inflammation while malignant diseases accounted for 48.3%. The order of frequency of the lesions was reactive hyperplasia (29.3%), metastatic cancer (24.5%), malignant lymphoma (23.8%), tuberculosis (15.6%) and toxoplasmosis (3.7%). One-third of the metastases were of undetermined origin. The neck which accounted for 53% of the biopsies, was the most frequent site for tuberculous adenitis, toxoplasmic lymphadenitis, and malignancies. The axilla was involved in 15% of the cases and was the most common site for metastatic breast carcinoma. The inguinal lymph nodes were also involved in 24% of the cases and had the highest occurrence of melanoma, reactive hyperplasia and parasitic granuloma. The habit of bare-foot walking leading to repeated trauma and infection is implicated in the high incidence of inguinal node reactive hyperplasia. This study demonstrates that lymph node malignancies and chronic granulomatous infections present a problem of increasing diagnostic and therapeutic importance and furthermore, it emphasizes that physicians in Nigeria should consider toxoplasmosis in the differential diagnosis of peripheral lymphadenopathy.

Recent findings suggested a possible role for pinhole collimator scintigraphy to differentiate between metastases, infection and fractures of the vertebrae. The aim of this study was to verify these findings and to ascertain whether we could identify any other specific scintigraphic patterns. The study group consisted of 58 patients. A metastatic pattern was obtained in 18 patients, while 16 showed the compression fracture pattern, 3 the tuberculosis pattern and 1 the pyogenic infection pattern. The study was considered normal in 4 patients and showed a nonspecific pattern in 4. Sensitivity was 85% for the metastatic pattern and 83% for the compression fracture pattern. Specificity was 94% for both patterns. Unique new patterns were identified in Paget's disease and in degenerative disease of the vertebrae (12 patients). Pinhole scintigraphy of the vertebrae is a valuable aid for detecting specific diseases of the vertebrae. Our findings suggest a valuable new role for skeletal scintigraphy, improving the specificity and obviating, in most cases of vertebral disease, the need for additional investigations.

Mean values for serum angiotensin-I-converting enzyme (SACE), determined spectrophotometrically in 648 subjects, using the synthetic substrate hippuryl-L-histidyl-L-leucine, and expressed in units per milliliter, were: controls, 11.11 +/- 3.97 (n = 89); lung cancer, 6.50 +/- 3.26 (n = 87); tuberculosis of the lung, 8.93 +/- 4.60 (n = 68); pulmonary sarcoidosis, 21.18 +/- 14.93 (n = 48); pneumonia, 9.81 +/- 6.83 (n = 52); fibrosis, 11.18 +/- 8.26 (n = 34); diabetes mellitus, 10.90 +/- 7.51 (n = 29); ischemic heart disease, 8.98 +/- 6.19 (n = 42); pulmonary embolism, 13.20 +/- 3.91 (n = 5); and lymphomas, 11.66 +/- 5.44 (n = 36). The lowest values for SACE (5.92 +/- 1.95) were observed in 7 patients with pulmonary metastases. No relationship could be found between SACE and other laboratory parameters, nor between the enzyme activity in men and women. Evidence suggests that low SACE activity is often associated with extrapulmonary cancers of various organs. Levels were significantly decreased in cancer of the lung and pulmonary metastases and significantly (p less than 0.001) increased in sarcoidosis compared with other diseases, suggesting that SACE activity may be of value in the diagnosis and prognosis of cancer of the lung.

This paper reports the results of 42 CT-aided fine needle biopsies of adrenal masses in 40 patients (26 were smaller than 3 cm., six smaller than 1 cm.). There were 25 adenomas, seven metastases, one primary carcinoma, one case of tuberculosis, two phaeochromocytomas and four post-inflammatory lesions. Diagnostic material was obtained in 88%. There was one incorrect diagnosis and on five occasions the result was indefinite, leading to an accuracy of 73%. Exclusion or demonstration of malignancy was, however, correct in 85%. There were no complications except for one unimportant pneumothorax.

Three cases of cancer treated with SSM (Special Substance, Maruyama: a polysaccharide extract from Mycobacterium tuberculosis) for a long period were studied pathologically following biopsies and autopsies. The most significant antitumor activity resulting from SSM treatment was found to be collagenation from stromal cells and the cancer cells themselves. Another significant finding was that collagenation was promoted by macrophages which had been stimulated non-specifically. However, it was apparent that SSM-A or B had to be used efficiently and quickly in order to prevent invasion or metastasis of cancer. Collagenation due to SSM treatment was more marked in metastatic cancer lesions in the liver than those in the lung. In a case of breast cancer reported in a previous investigation of SSM treatment, remarkable calcification was found in a metastatic cancer lesion which had become confined through collagenation, thus preventing cancer cell metastasis. The collagenation of cancerous lesions through SSM treatment resembled the healing of caseous tuberculosis lesions through a similar mechanism.

The value of pericardioscopy in pericardial effusion of uncertain origin was evaluated in 20 patients, aged from 18 to 77 years, whose pericardial effusion had been diagnosed by ultrasonography; 2 patients presented with clinical signs of tamponade. The cause of the pericarditis was unknown, but the clinical context suggested a malignant disease in 13 patients, tuberculosis in 5 patients and another cause in 2 patients. The pericardium was explored by means of a direct vision, cold-light endoscope, usually a mediastinoscope, introduced by the retroxiphoidal route under general of local anaesthesia. This method made it possible to study the pericardial fluid, examine the pericardial serous membrane, perform biopsies at a distance from the orifice of entry and cleanse the pericardium thoroughly in cases with blood or pus collection. Apart from 2 cases where the examination could not be completed because of an anterior mediastinal mass and a pericardial symphysis, valuable information could be obtained in purulent pericarditis (n = 1), chronic radiation induced lesions (n = 2), metastases (n = 2), haemopericardium (n = 2), and biopsies could be performed in tumoral or suspicious areas. These guided biopsies revealed a metastasis in 3 cases where the pericardial window was negative. No sign of tuberculosis was found in the 5 cases where the disease was suspected. The final diagnoses were: neoplastic pericarditis in 4 cases, radiation-induced pericarditis in 2 cases, purulent pericarditis in 2 cases, haemopericardium in 3 cases and idiopathic or reactive pericarditis in 9 cases. The post-operative period was uneventful, with no major complication ascribable to the procedure.(ABSTRACT TRUNCATED AT 250 WORDS)

A study was undertaken to determine the nature of non-thyroid neck masses among Nigerians. Under the age of 30 years tuberculosis accounted for 39% of cases; at the age of over 30 years metastases to lymph nodes was responsible for the majority (29%). Tuberculosis is not a major cause of neck masses in Nigerians over the age of 30. Primary lymphomas accounted for 23% of all cases, and were encountered uniformly in all age-groups. Congenital lesions like cystic hygroma, thyroglossal duct cyst, and branchial cysts were uncommon.

Levels of carcinoembryonic antigen(CEA)in the serum and pleural effusion in malignancies (65) and benign (25) of lung were determined. There are 20 cases of adenocarcinoma, 16 undifferentiated carcinoma, 7 squamous cell carcinoma, 4 alveolar carcinoma, 12 unclassified carcinoma, 1 polymorphous adenoma, 1 mesothelioma, 1 thymoma, 1 metastatic cancer from kidney and 2 metastatic breast cancer. In the benign lesions, there are 20 tuberculosis, 2 heart failure, 1 pneumonia, 1 empyema and 1 cirrhosis. The mean of the CEA level in the serum of lung cancer group was 12.63 ng/ml as compared with that of the tuberculosis group, 3.01 ng/ml (P less than 0.01). The level of CEA in pleural fluid in the lung cancer group was 57.30 ng/ml as compared with that of tuberculosis group, 5.55 ng/ml (P less than 0.01). The content of CEA in the serum and pleural fluid in lung cancer group was remarkably different (P less than 0.01). CEA level in the serum of adenocarcinoma is the highest (mean 15.51 ng/ml). If we set 5 ng/ml as the margin of normal CEA level in serum, the positive rate for cancer would be 54.2%. It is suggested that the margin of CEA normal value be set at 10 ng/ml for the pleural fluid. Higher readings may imply cancer.
