Pre-operative magnetic resonance imaging of stage 1 endometrial adenocarcinoma.

Twelve women with stage I endometrial adenocarcinoma were examined by magnetic resonance imaging before definitive surgery. Using this technique the depth of myometrical invasion, tumour site and cervical involvement were assessed and the results compared with the operative and pathological findings. Magnetic resonance imaging is a unique non-invasive method of assessing the early stages of endometrial adenocarcinoma before radiotherapy and surgery.

Isolated arteritis of the epididymis.

The clinical, histological, and immunohistochemical features of two cases of apparently isolated arteritis of the epididymis are presented. The aetiology and pathogenesis of the condition are discussed. Immunoglobulin and complement were shown in the acute arterial lesions, but this is not conclusive evidence that isolated arteritis is either an immune complex disease or a forme fruste of polyarteritis nodosa.

Unusual histological appearances of barium sulphate--a case report with scanning electron microscopy and energy dispersive x ray analysis.

Multiple birefringent rhomboidal crystals seen on histological examination of a resected oesophagus were subsequently found to contain elemental barium and sulphur on energy dispersive x ray ( EDX ) analysis. Scanning electron microscopy and EDX analysis of readily available commercial barium sulphate suspensions suggested that the two forms of barium sulphate previously described in tissue sections may be a result of the method of preparation of the commercial suspension used. With increased use of barium sulphate prepared by crushing the natural compound, birefringent rhomboidal crystals should be found with increasing frequency in endoscopic biopsy samples and resected specimens.

Hydatidiform mole in Nottingham: a 12-year retrospective epidemiological and morphological study.

The results of a 12-year retrospective study on the epidemiology of hydatidiform mole (HM) in Nottingham are presented. We have reviewed the histology of our cases of HM, tried to minimize selection bias, and have used the most reliable data available. Using data from two different sources we have calculated the frequency of HM as 1 in 1400 deliveries. The frequency of HM in this study is one quarter of that reported in an excellent study from Japan. We suggest that, with accurate epidemiological studies, the difference in frequency of HM between 'high risk' and 'low risk' areas is less than previously accepted. The present study also shows a lower incidence of persistent trophoblastic disease than previously generally accepted. We confirm that partial HM is a distinct clinicopathological entity and that two forms are distinguishable histologically. The malignant potential of partial HM is uncertain, and we suggest that the clinical management of partial HM should be no different from that of complete HM until further studies dictate otherwise.

Increased promoter diversity reveals a complex phylogeny of human immunodeficiency virus type 1 subtype C in India.

OBJECTIVE: To evaluate human immunodeficiency virus type 1 (HIV-1) long terminal repeat (LTR) sequence diversity among distinct populations within India and to determine the prevalent subtype. STUDY DESIGN/METHODS: Analysis of the 3'LTR was conducted from 28 HIV-1-positive samples: 1992-1993 (Pune, New Delhi) and 1995-1996 (Pune, Mumbai and Vellore). Genomic DNA was extracted from cocultivated peripheral blood mononuclear cells (PBMCs) and used for polymerase chain reaction (PCR) amplification and sequencing using dye terminator chemistry. Sequences were edited, aligned, and analyzed phylogenetically utilizing gap-stripped and bootstrapping parameters. Mobility shift assays were used to confirm binding activity. RESULTS: All nucleotide sequences were HWV-1 subtype C based on phylogenetic analysis. The isolates from Pune/Delhi formed subclusters when analyzed separately, irrespective of time or sample source. However, no significant subclustering was observed with isolates from Mumbai or Vellore or with the entire sample set when analyzed collectively. Subtype-specific enhancer analysis revealed an expected third NF-kappaB site but also revealed six isolates with insertions and deletions not previously described, one of which resembles an AP-1 binding site. CONCLUSIONS: The results confirm the prevalence of HIV-1C and suggest increasingly complex phylogeny of HIV-1C within India, such that the previously observed subclustering may no longer adequately reflect the diversity of isolates currently circulating throughout India.
