Study of C-reactive protein and C3 complement as acute phase reactants in unstable angina

Prevalence rates of coronary artery disease are reported to be very high in Asian Indians. Traditional risk factors alone fail to explain the high rates of coronary artery disease in Indians. Acute phase reactants C-reactive protein and C3 in Indian subjects with unstable angina were evaluated and compared them with suitable controls to test the hypothesis that a relationship exists between acute phase reactants and unstable angina. Forty cases of unstable angina and forty suitable controls were enrolled for the study. Cases of unstable angina had significantly increased level of CRP as compared to control group (p = 0.01098). Statistically significant difference was found between case and control groups in TLC (p = 0.0037) and ESR (p = 0.0368), TLC and ESR being more in case group as compared to control group. C-reactive protein was significantly correlated with TLC, ESR and C3 in case group and TLC and ESR in control group. C3 was significantly correlated with all the other three inflammatory markers. C-reactive protein, TLC and ESR in case group while no correlation was observed with any variable in control group. The present study concludes that a relationship exists between acute phase reactants studied and unstable angina.

Imaging spectrum in disseminated histoplasmosis: Case report and brief review

The clinical manifestations of chronic disseminated histoplasmosis are non-specific and resemble those of other chronic infections and malignancies. We report the radiographic, sonographic and contrast-enhanced CT appearances of histoplasmosis in an adult male with non-insulin dependent diabetes mellitus, who was HIV negative and presented with weight loss and pyrexia. Imaging studies simulated tuberculosis with mediastinal lymphadenopathy, bilateral fibrotic lung lesions, hepatomegaly and bilateral hypoattenuating adrenal enlargement, without clinical or laboratory evidence of hypoadrenalism. Computed tomography-guided fine-needle aspiration biopsy of adrenal glands revealed Histoplasma capsulatum. We report our experience to increase awareness of the imaging spectrum of disseminated histoplasmosis and its similarity to tuberculosis as, with increasing incidence of AIDS, the chances of these infections are likely to increase. Moreover, awareness of this entity is important because it is known that untreated disseminated histoplasmosis is fatal.

The effect of iron therapy on the growth of iron-replete and iron-deplete children

This prospective, double-blind, placebo-controlled trial was designed to study the effect of iron therapy on the growth of iron-replete and iron-deficient children, and to study the change in iron status in iron-deficient children with iron therapy. One hundred and fifty children (aged 6-24 months) were included in the study. After an informed written consent, 100 healthy children, who were iron replete (group I) according to preset criteria, were randomly allocated to receive iron supplements 2 ng/kg/day (group IA) or placebo (group IB). Fifty iron-deficient children (group II) were administered iron syrup 6 mg/kg/day. Growth parameters (weight, length and head-circumference) and hematological parameters were studied for 4 months. Iron therapy, as compared with placebo, produced a significant improvement of mean monthly weight gain (p < 0.001) and linear growth (p < 0.001) in the iron-deficient children. However, it significantly decreased the weight gain (p < 0.001) and linear growth (p < 0.001) of iron-replete children. Caution should therefore be exercised while supplementing iron to children with apparently normal growth and when the iron status of the child is not known.

Multiple myeloma presenting as primary non-secretory plasma cell leukemia

Primary plasma cell leukemia is a rare manifestation of multiple myeloma, whose neoplastic hierarchy in the classification of malignant hematological disorders is not yet very clearly defined. Morphological and immunological criteria indicate that the cells are at end stage of B cell maturation pathway. This unusual disorder is diagnosed by the presence of more than 2 x 10(9) plasma cells per liter of peripheral blood or more than 20% of the leucocytes being plasma cells on differential count. This occurs either denovo or as a terminal event in patients with long standing multiple myeloma. A case report of a young male patient with primary plasma cell leukemia is presented.

Pancytopenia--a clinico haematological study of 200 cases

The present study was designed to ascertain the percentage of occurrence and causes of pancytopenia. All the cases of pancytopenia from July 2001 to June 2002 (one year) were examined in the Department of haematology, Safdarjung Hospital, New Delhi. Bone marrow aspirations/biopsy were performed in most of the cases (200 out of 250 cases). The commonest cause of pancytopenia, in our hospital was Megaloblastic anaemia (72%), followed by Aplastic anaemia (14%) and others.

Primary malignant giant cell tumour of sacrum--a case report

A rare case of primary malignant GCT of sacrum in a 35-year-old female is reported.

Granulocytic sarcoma of humerus, an unusual association of acute myeloblastic leukemia--a case report

Ganulocytic sarcoma (Chloroma) is a tumour of rare variety usually in assocoiation with granulocytic leukemia. It is related to soft tissue with extramedullay infiltration. We present a case of granulocytic sarcoma of humerus which preceded the initial clinical manifestation of acute myeloid leukemia in a young patient which ultimately proved to be FABM2 variety. Though many tissues are affected by this tumour but the most favoured site is the bone.

Histoplasma capsulatum in adrenal gland aspirate--a case report

We report a case of disseminated histoplasmosis in a 60-year-old non-immunocompromised patient who presented to us with fever and hepatosplenomegaly. Sonographic & CT examination of the abdomen showed bilateral adrenal masses. Cytological examination of the aspirated material from the mass showed yeast forms of H. capsulatum.

FNAC of papillary and solid epithelial neoplasm of pancreas--a case report

A case of solid papillary epithelial neoplasm (PSEN) of pancreas in a young woman is reported in which the nature of tumour was recognised pre-operatively by ultrasound guided Fine needle aspiration. The pre-operative cytologic diagnosis enabled prompt and appropriate surgical treatment. FNAC revealed large cell clumps in the aspirate showing branching papillary appearance in which multiple layers of tumour cells surrounded central vascular stalks. The above was confirmed on histopathological examination of the excised tumour tissue.

Immunological assessment of infertility by estimation of antisperm antibodies in infertile couples

160 clinical samples were collected from 40 infertile couples with unexplained infertility. The samples collected included serum and seminal plasma of the male partners and serum and cervical mucus samples of the female partners. 25 fertile healthy couples were investigated as controls. All the samples collected were then tested for class-specific antisperm antibodies by an Enzyme linked immunosorbent assay (ELISA). Antisperm antibodies were detected in 30% of the infertile couples which included 25% female and 10% male partners. Amongst the cases positive for antisperm antibodies, antibodies were detected most frequently in female sera 58.4% followed by male sera 33% and 25% in cervical mucus. The isotyping of antisperm antibodies in various samples showed IgG to be the most frequent type specific antibody followed by IgM & IgA types of antibodies. ELISA has provided a relatively simple, reliable and highly reproducible method of detection of antisperm antibodies. Thus application of antisperm antibody testing especially in cervical mucus should become an integral part of the investigation of immunologic infertility.

A simple screening test for the detection of heterozygous beta thalassemia

Beta-Thalassemia is prevalent in a high frequency of 5-15% in selected geographical areas and ethnic communities. There is need to screen large populations for the heterozygotes of beta-Thalassemia. We have evaluated NESTROFT (Naked eye single tube red cell osmotic fragility test) with 0.36% buffered saline in this study. Of the population screened, 42 cases were positive with NESTROFT, of which 40 were positive with the confirmatory test for beta-Thalassemia. This implies a positive predictive value and specificity of 100%, negative predictive value of 83.3% and sensitivity of 95.2%.

Study on serum sperm agglutination in cases of unexplained infertility

In our study we investigated 100 couples of unexplained infertility in order to detect the presence of anti-spermatozoal antibodies. Both auto-immunity and Iso-immunity have been found responsible in 12.5% of couples of primary infertility & 10% of couples of secondary infertility. As many as, 21% of cases of unexplained infertility were attributed to presence of antibodies in sera of infertile couples. Here, we highlight the importance of anti-spermatozoal antibodies testing in the first instance itself in cases of unexplained infertility.

Cytohormonal evaluation of vaginal smears by phase contrast microscopy with special reference to progesterone deficiency pattern during early pregnancy as predictor of abortion

Cytohormonal profile of unstained vaginal smears were studied under phase contrast microscope to define various cell morphologies in detail and build up of smear pattern serially in various stages of menstrual cycle and first trimester of pregnancy. The findings were correlated clinically and found comparable to Papanicolaou stained smears. The maturation index was calculated more objectively by phase contract microscopy because of the refractile appearance of the pyknotic nuclei of superficial cells. The prognostication of abortion was done by combining abnormal maturation index and the presence of syncytiotrophoblasts in vaginal smears. Under phase contrast microscope, the sensitivity of abnormal smear was 87.5%, the specificity was 95%, the positive predictive value was 96.55% and the overall accuracy was 90% as compared to positive Papanicolaou smear whose sensitivity though 93%, had low specificity of 50% only. Phase contrast study appears to offer certain distinct advantage over the conventional light microscopy for quick, comprehensive and quantitative assessment of the study material. It allows the physician to detect changes in the material obtained from the patients without detour of laboratory fixation and staining. It is technically easy as errors in interpretation due to unsatisfactory fixation, staining and artefacts are obviated. Thus phase contrast microscopy offers an alternative and easy method of cytohormonal evaluation of wet and unstained smears.
