Tonsillar actinomycosis: a clinicopathological study.

Actinomycosis has been known to involve virtually every anatomic site in the body. Although actinomycosis has been identified in resected tonsils, its possible role in adeno-tonsillar disease has received little attention. A clinicopathological study of 302 patients who had adeno-tonsillar surgery is presented. Tonsillar actinomycosis was present in 86 (28.5%) patients. The statistical analysis revealed a significant association (P<0.0001) of actinomycosis and tonsillar hypertrophy (56.8%) compared to only 10.3% in the recurrent tonsillitis group. A statistically significant association (P<0.0001) of tonsillar actinomycosis and sickle cell anaemia, beta thalassaemia, bronchial asthma and beta haemolytic streptococcal infections was also seen. This data supports a predisposition of the above conditions to tonsillar actinomycosis and adeno-tonsillar hypertrophy and a possible etiopathologic role of this organism in adeno-tonsillar hypertrophy and disease. Although the clinical association of actinomycosis and tonsillar hypertrophy and beta haemolytic streptococcal infection has been described before the association of actinomycosis with sickle cell anaemia, beta thalassaemia and bronchial asthma is being observed for the first time in literature.

Anisakiasis of the tonsils.

A six-year-old Indian girl presenting with clinical features of chronic recurrent tonsillitis, had a tonsillectomy. Histopathology revealed a cross-section of an Anisakis worm in the tonsil. This report documents a new location in the human host for this rare parasite.

Pattern of hypertrophy of left ventricle--a histometric analysis of eighteen cases.

The pattern of myocardial hypertrophy in different sites of the left ventricular wall was morphometrically analysed in aortic stenosis (6 cases), hypertensive hypertrophy (5 cases), mitral incompetence (4 cases), and dilated cardiomyopathy (3 cases). The diameter of individual circumferentially oriented mid wall (or middle) fibre was significantly greater than those of subepicardial and subendocardial zones. Thus, hypertrophy does not affect the entire left ventricular myocardium uniformly. It seems to vary according to the spatial configuration of the fibrosis in relation to the cavity.

Autopsy findings and clinical diagnoses: a review of 1,000 cases.

The protocols of 1,000 consecutive adult patients autopsied during the period June 1983 to December 1988 were retrospectively analyzed and the findings were compared with clinical diagnoses. The autopsy rates during this period ranged between 23% and 27% of hospital deaths. Eighty-seven percent of the autopsied patients were between 15 and 59 years of age. Major discrepancies between the autopsy reports and the clinical diagnoses were present in 31.7% of all autopsy reports reviewed. Infectious diseases were the most common cause of death (46.8%), followed by cardiovascular diseases (17.1%) and neoplastic diseases (14.3%). Infections were clinically recognized in 66.7% of cases and were missed or found to be incorrect in 33.3% of cases. Tuberculosis comprised 33.8% of the major bacterial infections and was clinically diagnosed in 82% of cases. Eighty-nine percent of the major fungal infections were not suspected clinically. Rheumatic heart disease (43.8%) was the most common cardiovascular disorder and was clinically diagnosed in 93.3% of cases. Pulmonary vascular episodes were the least common cause of death and were not suspected clinically in 62.9% of cases. Malignancies were incorrectly diagnosed in 25.8% of cases. We conclude from this study that routine autopsies revealed major unexpected findings that are of clinical importance, and that a continued emphasis on autopsy evaluation is necessary for the improvement of the quality of patient care.

Intracardiac autonomic ganglion cells in leprosy and dilated cardiomyopathy.

Disturbances in cardiac autonomic functions are known to occur in patients of lepromatous leprosy and dilated cardiomyopathy. We have analyzed the number of cardiac autonomic ganglion cells in patients of lepromatous leprosy (2 cases), dilated cardiomyopathy (2 cases) and compared with those of control subjects (2 cases). The average number of ganglion cells in cases of dilated cardiomyopathy (1164) and leprosy (1138) did not show any significant deviation from the average neuronal number of control subjects (1352).

Adenoid cystic carcinoma in a bronchial washing. A case report.

A case of adenoid cystic carcinoma of the trachea and bronchi diagnosed on a bronchial washing is reported. This tumor has characteristic cytomorphology best elucidated by May-Grünwald-Giemsa stain.

Transbronchial lung biopsy in diffuse lung disease--a study of 28 cases.

Twenty-eight patients with diffuse lung disease underwent transbronchial lung biopsy during fibreoptic bronchoscopy. In 26 patients (93%) adequate tissue was obtained. Of these 26 biopsies specific diagnosis was possible in 20 (76%); a further 2 had non-specific inflammatory changes and a third, who was clinically normal, had normal lung. The inclusion of these cases raises the yield to 88%. The conditions most frequently seen were interstitial fibrosis (35%) and granulomatous diseases (31%). Three patients (11%) had procedure related pneumothorax; only one required a chest tube. This is a high yield, safe procedure and should be used more widely in India.

Anatomically isolated aortic valve disease. Morphologic study of 100 cases at autopsy.

Anatomically isolated aortic valve disease accounted for 1.1% of all and 5.2% of cardiac autopsies over a 20 year period. Among a total of 100 symptomatic cases, 52% had congenitally bicuspid, 43% had tricuspid and 5% had congenitally unicuspid valves. Nineteen percent had undergone fibrous sclerosis, including 1% unicuspid, 3% tricuspid and 15% bicuspid valves. Thirty nine percent had been affected by infective endocarditis, including 20 bicuspid and 19 tricuspid valves. The remaining 42 showed fibrocalcification, including 4 unicuspid, 17 bicuspid and 21 tricuspid valves. The nature of the valvular disease showed a correlation with the age of the patient. Infective endocarditis, fibrosis and calcific disease occurred in an ascending age pattern, at average ages of around 30 years, mid to late thirties and mid to late forties, respectively. The lesions occurred much earlier on the bicuspid than on the tricuspid valves, except for infective endocarditis. The bicuspid deformity was not found to make the aortic valve more prone to infection, nor did infection occur earlier on it than on the tricuspid valve. Four of the 100 cases, all tricuspid, were considered to be of rheumatic origin, the reasons for which are discussed. Certain well established associated cardiac lesions were identified.

Autopsy incidence of pulmonary vascular episodes. A study of 218 cases.

Pulmonary thromboembolism is a rarity in India. This common clinical impression has so far not been tested. Among 7000 autopsies between 1964 and 1980, a total of 218 cases (126 males and 92 females) were recorded to have thrombosis and/or embolism and/or infarction in the lungs. This incidence of 3.1% is far lower than that reported in the West and similar to the low incidence in Africa. Of the 218 cases, 42.6% had a cardiac disease, 18.3% had systemic septicemia, 13% had a malignancy, 12.8% had pulmonary disease, and the remaining suffered from diseases of liver, kidney, CNS, etc. Of the 218 cases, 141 (64.6%) showed only infarcts, 40 (18.3%) had only thromboemboli, and 37 (16.9%) showed both events. In view of the overlap among these three conditions and their essential pathophysiologic identity (thrombus/embolism/infarction), it is suggested that these be grouped under the name "pulmonary vascular episode."
