Study of apparently uninvolved skin in leprosy as regards bacillary population at various sites.

Slit smears form 16 LL and 4 BL patients were taken from scalp, axilla, inguinal regions and apparently involved skin patch. The bacilli were found in 100% LL and 75% BL patients at all sites. Scalp showed AFB in all LL and 3 out of 4 BL cases. No lesions were seen on the scalp. Bacterial morphology showed no uniform pattern. Contrary to belief, no immune zones were found on the skin as judged by results of bacteriological examination. Our studies do not support the view that the leprosy bacillus has a predilection for sites with relatively low temperature as far as human leprosy is concerned.

Evaluation of thyroid functions in leprosy. III. Circulating auto-antibodies against thyroid and nuclear components.

Sera from twenty six patients of various types of leprosy were tested for the detection of circulating auto-antibodies and nuclear components against thyroid using various methods. Four patients of lepromatous leprosy had higher levels of thyroid auto-antibodies by latex agglutination. Three patients showed the presence of anti-nuclear antibodies, two belonged to the TT and one to the LL group.

Evaluation of thyroid functions in leprosy. I. Thyroid function tests.

Twenty six patients of different types of leprosy were studied for radio active iodine uptake (I131) and serum levels of triiodothyronine (T3), thyroxine (T4) and thyroid stimulating hormone (TSH). None of the patients had clinical evidence of thyroid involvement. No significant difference was found between the values obtained in patients and normals and in different varieties of leprosy.

Fatal proliferative glomerulonephritis in lepromatous leprosy.

A patient of lepromatous leprosy with recurrent erythema nodosum leprosum developing acute renal failure proving fatal within 8 weeks is reported. The renal lesion demonstrated acute proliferative glomerulonephritis. Its pathogenesis in relation to ENL is discussed.

The role of Ga-67 citrate imaging and diagnostic ultrasound in patients with suspected abdominal abscesses.

Fifty patients with suspected abdominal abscesses were examined by [67Ga[ Gallium citrate imaging and abdominal sonography. Fifteen of the patients had a proven intra-abdominal abscess; Gallium-67 images were positive in 13 (87%), while the sonogram detected the abscess in 11 (73%). Nineteen patients had true-negative radionuclide images and sonography, and one had a false-positive result by both procedures. The remaining 15 patients did not have abdominal abscesses, but did have other abnormalities (e.g., pyelonephritis, extra-abdominal sites of inflammation) which were detected by the nuclide study. Gallium-67 imaging and abdominal ultrasound have similar sensitivity for detection of abdominal abscesses. A significant advantage of Gallium imaging is its ability to detect other inflammatory foci (both within and outside the abdomen).

Isolation, partial characterisation of antithiamine factor present in rice-bran and its effect on TPP-transketolase system and Staphylococcus aureus.

1. A light yellow viscous oily antithiamine compound designated as Compound X was isolated from rice-bran and it was composed of three components--glucose, a yellow viscous oily substance (Fraction A) and a reddish brown amorphous substance (Fraction B). 2. 1 mg of Compound X inactivated 3.5 microgram of thiamine hydrochloride whereas 1 mg of Fraction A inactivated 26.5 microgram of thiamine hydrochloride. Fraction B had no antithiamine activity. 3. Fraction A was partially characterised as benzene nucleus with ortho dihydroxyl groups, one methyl group and a side chain containing hydroxyl and carboxylic acid groups. 4. Compound X as well as Fraction A inhibited the utilisation of ribose-5-phosphate by TPP-TK system of human erythrocyte hemolysate and the growth of Staphylococcus aureus was retarded by these compounds.

Significance of delayed 67Ga localization in the kidneys.

One hundred and seventy-five 67Ga-citrate scans were performed to detect suspected occult inflammatory processes. None of the patients had a known malignancy. Renal activity was noted in 12 patients (6.8%) on the 48-hr image. These patients had either pyelonephritis, acute tubular necrosis, vasculitis, or a renal abscess. Since delayed 67Ga uptake in the kidneys may be the first evidence of renal disease, further investigation, including either arteriography or biopsy, is necessary. In patients with a known malignancy, tumor involvement must be considered.

Prognostic significance of endometrial extension from primary carcinoma of the uterinecervix.

This is a retrospective analysis of 302 patients with histologically confirmed primary carcinoma of the cervix on whom a dilatation and curettage was performed during the initial workup. The prognostic significance of endometrial extension of the tumor was investigated. Four different types of specimen were identified: 1) endometrial extension of cervical carcinoma; 2) cervical carcinoma in the currettings only; 3) a mixture of normal endometrium and and epidermoid carcinoma in the curettings; 4) no cervical carcinoma noted (negative D&C). The patients were staged according to the FIGO classification. Patients with Stage I carcinoma and positive D&Cs showed significantly lower 3-5 year survival rates (50-60 percent), as opposed to those with D&C.
