A prospective study of 595 patients treated by the Thoracic Surgical Unit (TSU) at the University College Hospital (UCH), Ibadan between July 1975 and December 1977 was carried out to determine the pattern of thoracic surgical diseases in Nigeria and to prove or disprove the rarity of certain cardiopulmonary diseases in tropical Africa. This review shows that pyogenic infections of the lung and pleura constitute the largest percentage (38.5) of the thoracic surgical diseases in Nigeria. Although pulmonary tuberculosis accounts for only 23.4 percent of our total inpatient load, it constitutes about 60 percent of our outpatient clinic practice. Cardiovascular diseases form 12.9 percent, notably congenital and acquired valvular heart diseases. An interesting finding was the occasional association of pyomyositis with pyogenic pericarditis and empyema thoracis. This triad is being investigated. Chest trauma was the most common thoracic surgical emergency accounting for 9.2 percent of the total thoracic surgical pathology. The most common causes of dysphagia are strictures from corrosive esophagitis, achalasia, and carcinoma of the esophagus. Present experience confirms the rarity of hiatus hernia, reflux esophagitis, atherosclerotic cardiovascular disease, and, perhaps, carcinoma of the lung among Nigerians.

An edited summary of an Interdepartmental Conference arranged by the Department of Medicine of the UCLA School of Medicine, Los Angeles. The Director of Conferences is William M. Pardridge, MD, Professor of Medicine. Several specialists have recently recognized that gastrointestinal reflux causes complications resulting in significant disease. It causes discomfort, indigestion, esophagitis, Barrett's esophagus, and carcinoma of the esophagus. Pediatricians attribute many early pulmonary problems, and even some sudden deaths in infants, to the reflux of gastric contents. Otolaryngologists now recognize that many cases of nonbacterial, nonspecific pharyngitis and laryngitis are due to the reflux of gastrc acid secretions. Contact granuloma and cancer of the larynx may, in some instances, be secondary to nocturnal reflux. Thoracic surgeons and pulmonologists believe chronic tracheobronchitis and some cases of pulmonary disease are attributable to recurrent bathing of the respiratory epithelium by aspirated gastric contents. An awareness of the many complications of gastrointestinal reflux should lead to a multidisciplined attack on the factors responsible for these diseases.

Twelve patients with oesophageal smooth muscle tumour were operated on between 1955 and 1984 in the Department of Thoracic and Cardiovascular Surgery of Helsinki University Central Hospital. Eleven tumours were leiomyomata, the twelfth was a leiomyosarcoma. Dysphagia (83%) and chest or epigastric pains (67%) were the most common symptoms presented. All patients underwent transthoracic removal of the tumour. Complications of the surgery included two cases of postoperative oesophageal fistula; in both instances the lumen of the oesophagus had been entered during the extirpation of the tumour. The surgery was effective in eliminating the most prominent symptom, i.e. dysphagia. However, follow-up examinations 11.1 +/- 6.8 (SD) years later revealed reflux symptoms and endoscopically and histologically verified oesophagitis in seven of the nine (78%) surviving patients. Additionally, two of them had developed Barrett's oesophagus, 10 and 19 years, respectively, after the primary surgery. These two patients underwent subsequent transabdominal antireflux procedures (Nissen fundoplication). We conclude that long-term follow-up of patients who have been treated for benign oesophageal tumour is indicated.

The incidence, clinical and investigative features, treatment, and course of severe oesophagitis in 200 patients seen and followed up in the Thoracic Surgical Department for north east Scotland from 1951 to 1967 are reviewed. The male/female ratio was 1/1.9. The incidence of severe oesophagitis (grades III and IV) approximated to 4.5 per 100,000; there was a dramatic increase from the age of 50 years onwards.Reflux, with or without hiatal hernia, precedes oesophagitis and has an incidence in excess of 86 per 100,000. It is difficult to assess the extent to which reflux produces mild oesophagitis, but it is clear that it only infrequently leads to the severe grades. Severe oesophagitis does not always need operative treatment. A conservative regime, supplemented by bouginage as required, enables the poorer-risk older patient to live a near-normal life span, in very reasonable comfort. Fifty-three patients of the whole series were operated upon, half primarily and half after previous conservative treatment. The problems of operative treatment are discussed. Newer procedures designed to prevent reflux now allow operation to be more freely advised.Perhaps, rather surprisingly, severe oesophagitis had very little effect on the expectation of life, whether treatment was conservative or operative.

The acquired immune deficiency syndrome is characterized by the development of multiple recurrent opportunistic infections or unusual neoplasms in individuals with no prior history of immune suppression. This report summarizes the thoracic diseases encountered in such patients before after death and the role of diagnostic techniques currently used in the evaluation of thoracic disease in 15 patients with this syndrome. Efficacy of treatment was determined by correlation with postmortem findings in all patients. Pulmonary disease was present in all 15 patients and necessitated 23 transbronchial biopsies in 11 patients. Pneumocystis carinii pneumonia and cytomegalovirus pneumonia were the most common findings. Nine open lung biopsies in eight patients disclosed either Pneumocystis carinii pneumonia or Kaposi's sarcoma. Esophageal disease was present in four patients, and endoscopic evaluation demonstrated Candida esophagitis (two), esophageal Kaposi's sarcoma (one), and cytomegalovirus esophagitis and Kaposi's sarcoma (one). Mean time to death from diagnosis of acquired immune deficiency syndrome was 7.7 months, with respiratory insufficiency being the most common cause of death (9/15, 60%). Pneumocystis carinii pneumonia was successfully eradicated in 70% of the patients. Candida esophagitis was ameliorated in both patients with the disease. Unsuspected pulmonary Kaposi's sarcoma, cytomegalovirus pneumonitis, and other infectious pathogens were documented at autopsy. These data reveal that Pneumocystis carinii pneumonia and Candida esophagitis can be managed successfully in patients with acquired immune deficiency syndrome if appropriately diagnosed. The major cause of death in this series was pulmonary insufficiency, often the result of severe cytomegalovirus infection. Thoracic surgeons must continue to play an aggressive and important role in the early diagnosis and management of potentially treatable pulmonary and esophageal disease in these patients.

Nine patients with stage IIIB non-small cell lung cancer were entered into a phase II trial designed to determine the feasibility of giving a combination of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) plus cisplatin concurrent with thoracic radiation. Paclitaxel was given as a 24-hour infusion (135 mg/m2) followed by cisplatin (75 mg/m2) every 4 weeks, for a total of four cycles. Thoracic radiation was given concurrently with the first two cycles of chemotherapy, for a total dose of 64.8 Gy over 6 weeks. Neutropenia and esophagitis were the most common toxicities, with 66% of patients experiencing grade 3 or 4 neutropenia and 55% experiencing grade 3 or 4 esophagitis. Grade 3 pulmonary toxicity developed in 33% of patients. All patients were able to receive the full dose of radiation, although half of the patients required some modification of the chemotherapy regimen. There was one complete response and four partial responses, yielding a 56% overall response rate. This study demonstrates that it is feasible to treat patients with stage IIIB non-small cell lung cancer with paclitaxel/cisplatin plus concurrent thoracic radiation, with a degree of toxicity comparable with that associated with a degree of toxicity comparable with that associated with other concurrent combined-modality regimens for this disease.

Ambulatory simultaneous recording of oesophageal pressures and pH is a recently developed technique for evaluation of oesophageal function. The paper describes the experience gained with this technique at the Oesophagus Laboratory, department of Thoracic and Cardiovascular Surgery T, Odense University Hospital. A combined pH and pressure probe is positioned in the oesophagus and connected to a portable recorder. Data are digitised on-line and stored for later transfer to a computer. Analysis of pH-variations and contractile activity is performed automatically. Sections with normal and abnormal acid clearing are shown. A normal pressure response to reflux consists of frequent contractions of normal amplitude and propagation resulting in a stepwise clearing of acid from the oesophagus. Repetitive simultaneous contractions and periods of failed peristalsis are illustrated in sections from a patient with oesophagitis. Contractions of high amplitude and prolonged duration, as well as frequent non-propagating contractions in the distal oesophagus, are elements of a normal peristaltic pattern. The conventional manometric investigation performed under laboratory conditions still has first priority when esophageal dysmotility is suspected. In several instances, however, ambulatory recording of motility and pH may add valuable additional information.

Knowledge of common and uncommon thoracic pathologic conditions in children with acquired immunodeficiency syndrome (AIDS) can expedite disease management. Chest radiography, computed tomography (CT), and magnetic resonance (MR) imaging are useful in cases involving possible complications of thoracic AIDS. Lymphocytic interstitial pneumonitis (LIP) is generally seen on plain radiographs and CT scans as a diffuse, symmetric, reticulonodular or nodular pattern, occasionally associated with mediastinal or hilar adenopathy. Chronic consolidations and bronchiectasis may be observed in pediatric AIDS patients with no evidence of previous LIP. Bacterial pneumonia, a frequent initial manifestation of AIDS, appears as lobar or segmental consolidations on radiographs. Radiographic findings of Pneumocystis carinii pneumonia, the most common infection, include rapidly progressive increased air-space opacity with air bronchograms. Lymphoma often appears as a mediastinal or hilar mass, often without involvement of the lung parenchyma. Thoracic smooth muscle tumors have also been observed in children with AIDS. Multilocular thymic cysts have low attenuation on CT scans and increased signal intensity on T2-weighted MR images. Most pediatric AIDS patients with cardiac disease have cardiomegaly, often associated with pulmonary edema, at chest radiography. An esophagogram may show ulceration, plaque formation, mucosal edema, and dysmotility in patients with candidal esophagitis.

We evaluated the feasibility and efficacy of combination paclitaxel (Taxol) (via 1-hour infusion), carboplatin (Paraplatin), and oral etoposide (VePesid) in the first-line treatment of patients with small-cell lung cancer. Between June 1993 and July 1996, 117 patients with small-cell lung cancer. were treated in two sequential phase II studies. The first 38 patients received a lower-dose regimen: paclitaxel 135 mg/m2, via 1-hour infusion; carboplatin dosed to an area under the concentration-time curve (AUC) of 5.0, and oral etoposide 50 mg alternating with 100 mg on days 1 through 10. Based on a very favorable toxicity profile, the paclitaxel and carboplatin doses were increased in the subsequent cohort of 79 patients (paclitaxel 200 mg/m2 by 1-hour infusion; carboplatin target AUC increased to 6.0). Thoracic radiation therapy (1.8 Gy/day; total dose, 45 Gy) was administered concurrently with courses 3 and 4 of chemotherapy in patients with limited-stage small-cell lung cancer. The combination of paclitaxel 200 mg/m2, carboplatin to an AUC of 6.0, and extended-schedule oral etoposide 50 or 100 mg alternating days 1 through 10 is highly active and well tolerated in patients with small-cell lung cancer. The regimen can be administered concurrently with radiation therapy with no unusual side effects, although a minority of patients develop esophagitis. Median survival rates in patients with both extensive- and limited-stage disease compare favorably with other reported regimens.

A study to evaluate the efficacy of cisplatin, doxorubicin, and etoposide chemotherapy with combined radiotherapy was undertaken in 26 patients with limited disease-small-cell lung cancer. Patients were treated with cisplatin (80 mg/m2) intravenously (i.v.) on day 1, doxorubicin (30 mg/m2) i.v. on day 1, and etoposide (80 mg/m2) i.v. on days 1, 3, and 5, every 4 weeks for four cycles. Thoracic irradiation of 40 Gy in 20 fractions was delivered during 4 weeks to the primary site starting on day 8 of the second cycle of chemotherapy. The objective response rate was 100%. A complete response was observed in 10 patients (38%). The median survival time was 23 months, and the 3-year survival rate was 42%. Seven patients (27%) continued to survive at least 8 years and remain free from disease. Grade III/IV leukopenia was observed in 25 patients (96%). Grade III/IV thrombocytopenia developed in 19 patients (73%). Grade III/IV esophagitis was not seen. Interstitial pneumonitis occurred in two patients. This regimen is effective and has acceptable toxicity for use in the treatment of limited disease-small-cell lung cancer.
