Psammoma bodies in fine needle aspiration cytology of the breast: a clinicopathological study of 30 cases.

Psammoma bodies (PBs) in breast lesions are rare and little is known about the role of these structures in breast pathology. This study has looked in to the diagnostic significance of PBs in fine needle aspiration (FNAC) of breast lesions. Over a 5-year period, FNACs of the breast were done in 4,563 subjects, of which 1,678 were diagnosed to be malignant. On review of all breast aspirates including non-neoplastic lesions, 30 cases showed PBs to be associated with breast carcinoma (BC). Cytological features were correlated with clinical, radiological, histological, and immunohistochemical findings. All 30 aspirates and their corresponding histological sections showed varying number of PBs and nonpsammomatous bodies (NPBs). For comparison, 31 cases of age-matched BC without PBs and NPBs in both aspirates and sections were studied. Statistical analysis using Chi-square test was done to compare BC with and without PBs. BC with PBs was characterized by papillary pattern of malignant cells, mucin in the background, infiltration by macrophages, cellular degeneration, overexpression of estrogen receptor (ER), and progesterone receptor (PR) and moderate positivity (2+) for Her2/neu. Calcium deposition has long been implicated in the pathogenesis of many degenerative diseases; hence the formation of PBs may be relevant in breast oncology. The presence of PBs in FNAC of clinically suspected breast lesions which are cytologically negative for malignancy warrants further histological confirmation.

Psammoma bodies in cervical smear in association with keratinizing squamous cell carcinoma of cervix: a case report.

The presence of psammoma bodies (PBs) in cervical smears is a rare finding. These structures have been identified in association with a wide range of benign and malignant conditions within the female genital tract. PBs in cervical smears have usually been associated with malignant serous epithelial ovarian tumors. However, many PBs associated with atypical squamous cells were detected in cervical smears of an 83-year-old woman with complaint of postmenopausal bleeding. Colposcopic examination revealed an ulceroinfiltrative growth in the cervix. Histological examination of the biopsy specimen from the growth revealed keratinizing squamous cell carcinoma with multiple and singly arranged PBs. This report suggests that cytologists should aware of the possibilities, on finding PBs associated with atypical cells in cervical specimens and report the cases accordingly.

Mucinous carcinoma of breast with abundant psammoma bodies in fine-needle aspiration cytology: a case report.

Fine-needle aspiration (FNA) cytology plays an important role in the diagnosis of various pathologic conditions in the breast. Microcalcification can be observed in benign and malignant breast lesions, but psammoma bodies (PBs) are rarely reported in breast lesions and are a feature of papillary neoplasms. However, we have observed PBs in large numbers in a mucinous carcinoma of breast, which is not previously reported in FNA of breast lesions. A 65-yr-old postmenopausal woman underwent FNA of a palpable mass. The aspirate revealed mucinous carcinoma cells associated with plenty of PBs. This case report of mucinous carcinoma of the breast with abundant PBs highlights the cytodiagnostic pattern of the lesion and formation of PBs.

Cancer in women in Kerala--a transition from a less-developed state.

An epidemiologic assessment of the problem of cancer in women in Kerala based on 3 Population Cancer Registry data and a Hospital Based data is presented. Kerala's Socio-economic and demography presents an intermediate development from a less developed to a better-developed state. As yet, the women follow a tradition-based life style. Cancer incidence rate in Kerala was only 80% of urban rates than seen in Urban Metropolis in India. The pattern of site distribution has shown that GI, Breast and Cervix cancers are the predominant cancers. Oral cavity cancers also show a high frequency. Thyroid cancer has a higher incidence rate in Kerala compared to other areas. Lung cancer among women has higher incidence rate in Karunagappally women. A high prevalence of tobacco use is reported among the men in the above area. Breast cancer incidence rate in the rural areas was only 60% of the rate seen in Urban Trivandrum. Unlike in other rural and urban areas of India Cervix cancer has a low incidence rate in Kerala women. This may be due to better education and also due to the changes in marital and other life style practices. Only 15% of cancer patients attend for medical assistance in localized stage of disease. The need for public education is highlighted and focusing on tobacco use control, self-examination and screening.

Epilepsy control with phenobarbital or phenytoin in rural south India: the Yelandur study.

BACKGROUND: Epilepsy is a controllable disorder if detected and treated early. For most families in rural areas of less developed countries, however, treatment can be delayed because of the inaccessibility of specialist neurological assessment facilities. We aimed to find a practical solution to rural epilepsy control by doing a non-randomised trial in south India. METHODS: 135 patients with partial or generalised tonic-clonic seizures agreed to long-term treatment with phenobarbital (n=68), phenytoin (n=60), or both (n=7). Drugs were given once daily, and at the lowest effective dose, by trained primary-care physicians and health workers. All management was entirely clinical. The main outcome measure was absence of seizures of any type for at least 2 years (terminal remission). Analysis was by intention to treat. FINDINGS: The proportion with terminal remission at each of 4 successive years of follow-up ranged from 58% to 66% for patients who were drug compliant and who had a lifetime total of 30 or fewer generalised tonic-clonic seizures. The corresponding range for patients who were not compliant and who had ever had more than 30 such seizures was 6-16%. Multivariate logistic regression analysis confirmed that strict drug compliance and early treatment were important predictors of a 2-year terminal remission. Clinical adverse effects were noted in three (4%) patients on phenobarbital and 67 (43%) of those on phenytoin (mainly in the form of gingival hyperplasia). INTERPRETATION: In rural areas of less developed countries, epilepsy control in its early stages can be practical and effective with existing resources. The key to success is a combination of trained primary-care physicians, health workers, inexpensive phenobarbital, drug compliance, health education, and follow-up.

The Yelandur study: a community-based approach to epilepsy in rural South India--epidemiological aspects.

Data on the epidemiology of epilepsy in a rural community in a developing country would be of value in planning a decentralized management of this malady in its early stages commensurate with available local resources. A detailed screening instrument covering various seizure types was used by trained paramedical workers in a door-to-door survey of a population of 64,963 in rural South India. The prevalence period was from 1 April 1990 to 31 March 1991. The crude prevalence rate per 1000 for active epilepsy was 4.38 for males, 3.40 for females and 3.91 for both. The minimum and maximum prevalence rates, the latter computed from a validation sample, were 3.91 and 4.63 for active epilepsy; 0.28 and 0.77 for inactive epilepsy and 4.19 and 5.41 for life-time prevalence. In addition, corresponding figures for hot-water epilepsy, a type of reflex epilepsy peculiar to this area, were 2.49 and 2.99 for active phase; 0.35 and 0.85 for inactive phase and 2.85 and 3.83 for life-time prevalence. The incidence rate for epilepsy was 49.3 per 100,000, the same as in developed countries. These data do not support the concept that the prevalence of epilepsy in developing countries is twice that in the developed world. However, the role of local/regional variations should be borne in mind before extrapolating the figures to an entire country.

Epilepsy: legal discrimination from negative to positive.

Indian law equates epilepsy with temporary insanity and also prohibits a legally valid marriage for a person with epilepsy with inherent risk of divorce. This absurd law, unique to India and possibly Brazil, must be excised in toto. Repeated petitions, by the Indian Epilepsy Association, to the Federal Government, have resulted in only vague assurances and alternate methods are under consideration. There are no legal impediments to education or work. Strict regulations against driving have yielded place to lax rules wherein a person can drive a vehicle, even after a recent fit, provided he gets a certificate from any registered medical practitioner. The nascent medical insurance specifically excludes epilepsy from its ambit. The cost of anti-epileptic drugs includes a 40% tax akin to Value Added Tax in the West. We must consider the impact of these legal impediments on the social fabric of the individual in his/her milieu and vis-a-vis priorities in national development.

Low dose radiation--a curse or a boon?

The increased use of nuclear technology has created fear in the minds of people regarding its possible adverse effects on living systems. This fear is heightened by press reports of nuclear fallouts and of high levels of natural background radiation in geographical areas in a number of countries. The International Commission on Radiological Protection and the United Nations Scientific Committee on the Effects of Atomic Radiation estimate the risk of cancer from high dose exposure to be 4.5% to 7.1% per sievert depending on the projection model used. However, when the exposure is to low dose background radiation, the available data does not show an increased risk. This is possibly due to the effectiveness of the inherent repair capacity of the living cell. These observations have given rise to the 'hormesis' hypothesis. Low dose radiation has in fact been found to be immunostimulatory and this is now being exploited as a possible treatment modality in cancer patients.

Seizure prognosis for partial epilepsies in India.

The long-term prognosis and factors associated with good and poor prognosis were studied in 95 patients with partial seizures. Thirty-nine per cent of the patients became seizure free. Significant prognostic factors were: male sex, most attacks while awake, attacks precipitated by a hot-water bath, presence of autonomic phenomena and complex symptoms, chronicity and severity of the illness, and seizure activity and the presence of symmetric synchronous EEG foci in the initial EEG records. Regularity of medication, duration of illness and autonomic phenomena were 3 predictive factors for long-term prognosis.
