RESUMO
Solitary fibrous tumour of the pleura is a rare primary pleural neoplasm. These tumours are usually asymptomatic and are incidentally detected. Majority of these neoplasms are benign and surgical excision provides excellent results. With the widespread use of imaging and better diagnostic criteria, this tumour is likely to be detected more frequently. We encountered a patient with a giant solitary fibrous tumour of the pleura. In this report, we describe the case of a patient with a giant solitary fibrous tumour of the pleura, review the literature and present the details of management of this patient.

BACKGROUND: The technique of Fluorescence In-Situ Hybridization (FISH), a hybrid of cytogenetics and molecular biology has increased the resolution and application of cytogenetics in various neoplastic processes. In various types of leukemias, primary investigation by conventional cytogenetic [CC] technique followed by FISH has increased our understanding of the abnormal clonal formation involving different gene region. AIMS: Present study is aimed to use different kinds of in-house FISH probes in various hematological malignancies and its correlation with conventional cytogenetic finding. MATERIAL AND METHODS: Cytogenetic study was carried out in 360 patients either from peripheral blood or from bone marrow cells suspected for various types of leukemias. Four of 360 cases were further selected for FISH study by using different types of in-house probes, such as BAC [Bacterial Artificial Chromosome], PAC [Phague Artificial Chromosome], alphoid, PCP [Partial Chromosome Paint] and WCP [Whole Chromosome paint]. RESULTS: The results confirmed breakpoints of inversion 16 and del 16 in case 2 and 3 respectively. Whereas, case 1 did not confirm the cytogenetic findings of t(15;17) by PML/RARa fusion signals as multiple cell lines were involved in the patients. PCP and WCP were helpful in the identification of the marker chromosome in case 1. Telomeric and centromeric probes confirmed the cytogenetic findings of t(5;7) in case 4. CONCLUSION: We observe from this study that, in addition to the conventional cytogenetic study, FISH study provide further confirmation of chromosomal rearrangements. This facilitates our understanding of the neoplastic process more precisely for the better prognostication of the patient.

Present study consists of cytogenetic evaluation in 141 cases referred to our centre for various leukemias. This includes 110 cases of CML, 10 of ALL, 16 of AML (M3), 2 of AML(M2), 2 of MDS and 1 of CMML. The conventional cytogenetic study was carried out in all the cases using G Banding technique. Of the 141 patients studied, 17 patients showed secondary chromosomal alterations along with primary chromosomal alterations. In two patients of CML with secondary chromosomal alteration t(4:9:22), molecular cytogenetic technique (FISH) has been carried out which has confirmed the primary observations revealed by the conventional cytogenetic technique. Other secondary alterations were numerous and would have been missed if only FISH or PCR technique would have been used for diagnosis. We observed from our study that advanced molecular techniques like FISH and PCR cannot replace the conventional cytogenetic study but are useful as supportive and confirmative diagnostic tools.

A study was conducted to assess exclusive breast-feeding, continued breast-feeding, bottle-feeding, predominant breast-feeding, timely complementary feeding and other breast-feeding practices in 818 children in the age group of 0-3 years belonging to the Schedule Caste communities of Haryana. The exclusive breast-feeding rate was 0.15 and the predominant breast-feeding rate 0.75 in children < 4 months. Timely complementary feeding rate was 0.42. The continued breast-feeding rate at 1 year and 2 years was 0.84 and 0.58, respectively. The bottle-feeding rate, ever breast-fed rate, timely first-suckling rate and exclusive breast-feeding rate by mother were 0.09, 1.0, 0.0 and 0.15, respectively. The median duration of breast-feeding was 16 months.
