Nipple Aspirate Cytology And Pathologic Parameters Predict Residual Cancer And Nodal Involvement After Excisional Breast Biopsy., E R Sauter, H Ehya, A Mammen, G Klein

We previously demonstrated that abnormal nipple aspirate fluid (NAF) cytology predicted residual breast cancer (RC) and tumour size after excisional biopsy (EB), although normal NAF cytology did not exclude RC. Tumour size correlates with the risk of lymph node (LN) metastases. LN metastases provide prognostic information allowing medical and radiation oncologists to determine the need for adjuvant therapy. We hypothesized that pathologic factors known after EB, combined with NAF cytology, would predict with a high degree of accuracy the presence of RC and LN spread. NAF cytology and pathologic parameters: tumour distance from biopsy margins, multifocal and multicentric disease, sub-type …

Background
Pelvic floor disorders affect almost 50% of aging women. An important role in the pelvic floor support belongs to the levator ani muscle. The p27/kip1 (p27) protein, multifunctional cyclin-dependent kinase inhibitor, shows changing expression in differentiating skeletal muscle cells during development, and relatively high levels of p27 RNA were detected in the normal human skeletal muscles.
Methods
Biopsy samples of levator ani muscle were obtained from 22 symptomatic patients with stress urinary incontinence, pelvic organ prolapse, and overlaps (age range 38–74), and nine asymptomatic women (age 31–49). Cryostat sections were investigated for p27 protein expression and type I (slow …

Objective: To delineate the spectrum of salivary gland tumors in our setup.
Setting: The Aga Khan University Medical Centre, Karachi.
Method: Tumors were analysed considering histological type, age and sex of the patients and anatomic location. The diagnosis of individual tumours was based on the 1991 World Health Organisation Classification.
Results: During the span of eight years (1991-1998), 379 cases of salivary gland tumours were diagnosed. Of these, 205 (65.7%) were male and 174 (34.3%) were female. The median age at the time of diagnosis was 35 years. The median age for patients with malignant lesions (44 years) was 12 …

Interactions Among Murine Cytomegalovirus Us22 Family Gene Products That Influence Viral Pathogenesis, Zaruhi Karabekian
Interactions Among Murine Cytomegalovirus Us22 Family Gene Products That Influence Viral Pathogenesis, Zaruhi Karabekian
Theses and Dissertations in Biomedical Sciences
Cytomegalovirus (CMV) is a complex, ubiquitous herpesvirus that is characterized by acute, chronic, and latent infections. Monocytes-macrophages are the key target cell type involved in pathogenesis, which is most effectively studied using the murine model of CMV infection. Previously three murine CMV (MCMV) genes (M139, M140, and M141) were identified to regulate viral expression in cultured macrophages and in mice. These genes are members of the US22 gene family with respect to HCMV homology. There is no function assigned to the proteins encoded by these genes. However, deletion of M139, M140, and M141 significantly curtails growth of MCMV in macrophages …

Objective: To complete the data on the demographic features of patients diagnosed to have aplastic anemia at a single institution over a 7.5 years period. Methods: Demographic information was retrieved from the patients medical records retrospectively as well as prospectively of those patients who presented with features of aplastic anaemia. Their diagnosis was confirmed by performing a complete blood count and bone marrow trephine.
Results: One hundred and forty four patients were diagnosed to have aplastic anemia; there were 106 males and 38 females. Their ages ranged from 2 to 75 years, with a median of 17 years, …
Acute Haemolysis In Childhood Falciparum Malaria, H. Ekvall, P. Arese, F. Turrini, K. Ayi, F. Mannu, Zul Premji, A. Bjorkman
Acute Haemolysis In Childhood Falciparum Malaria, H. Ekvall, P. Arese, F. Turrini, K. Ayi, F. Mannu, Zul Premji, A. Bjorkman
Pathology, East Africa
Acute haemolysis associated with clinical episodes of high-level Plasmodium falciparum parasitaemia was studied in 20 children from an holoendemic area (coastal Tanzania). The change in blood haemoglobin (Hb) concentration ranged from -46 to +5 g/L during the 72-h observation period and was linearly related to maximum parasitaemia. Balance studies between loss of blood Hb, increase in plasma Hb and appearance of Hb in the urine indicated that extravascular clearance of red cells was the predominant mode of erythrocyte clearance. Most subjects, however, showed minor signs of intravascular haemolysis. The plasma Hb was ≪1% of blood Hb and haemoglobinuria was detected …

Hemoglobin Concentration In Children In A Malaria Holoendemic Area Is Determined By Cumulated Plasmodium Falciparum Parasite Densities, H. Ekvall, Zul Premji, S. Bennett, A. Bjorkman
Pathology, East Africa
In malaria holoendemic areas children are anemic, but the exact influence of falciparum malaria on hemoglobin (Hb) concentration remains largely unsettled. Prospective data were therefore collected in children < 24 months of age during five months in a Tanzanian village. Children with mean asymptomatic parasitemia ≥ 400/μl had lower median Hb levels during the study than those with mean density < 400/μl. The difference was 9.7 g/L (95% confidence interval [CI] 2.8-17). In children with one or more clinical malaria episodes, the median Hb was 8.3 g/L (95% CI 0.9-16) lower than those without episode. If early treatment failure was recorded, the immediate effect on Hb was particularly important with a mean drop of 17 g/L. Interestingly, at study-end the Hb concentration represented a function of the area under the parasitemia curve (AUPC) during the previous five months, adjusting for age. In conclusion, stepwise deterioration in median Hb levels was found by asymptomatic parasitemia, clinical malaria episode, and most significantly, treatment failure.

An Analysis Of Anemia And Child Mortality, B.J. Brabin, Zul Premji, F. Verhoeff
Pathology, East Africa
The relationship of anemia as a risk factor for child mortality was analyzed by using cross-sectional, longitudinal and case-control studies, and randomized trials. Five methods of estimation were adopted: 1) the proportion of child deaths attributable to anemia; 2) the proportion of anemic children who die in hospital studies; 3) the population-attributable risk of child mortality due to anemia; 4) survival analyses of mortality in anemic children; and 5) cause-specific anemia-related child mortality. Most of the data available were hospital based. For children aged 0-5 y the percentage of deaths due to anemia was comparable for reports from highly malarious …
Impaired Splenic Function In Systemic Amyloidosis: Diagnostic Importance Of Peripheral Blood Film, F. Bilwani, Salman Adil, G. N. Kakepoto, Mohammad Khurshid, A. Ahmed
Impaired Splenic Function In Systemic Amyloidosis: Diagnostic Importance Of Peripheral Blood Film, F. Bilwani, Salman Adil, G. N. Kakepoto, Mohammad Khurshid, A. Ahmed
Department of Pathology and Laboratory Medicine
We describe case of a 40 year old male, who went on to developed systemic amyloidosis 3 years after the diagnosis of chronic renal failure. The diagnosis of systemic amyloidosis was suspected upon a routine examination of periheral blood film showing features of hyposlenism. We would like to highlight the importance of examination of pheripheral blood film in patients with renal failure for the diagnosis of extensive systemic amyloidosis which occasionally leads to functional hyposplenism, recognized by the presence of abnormal red cell morphology and reduced splenic uptake on isotope scan1.

BACKGROUND: Synaptopodin is a proline-rich protein intimately associated with actin microfilaments present in the podocytes' foot processes. We investigated for synaptopodin expression in children with idiopathic nephrotic syndrome (INS), including minimal change disease (MCD), diffuse mesangial hypercellularity (DMH), and focal segmental glomerulosclerosis (FSGS); in children with congenital nephrotic syndrome of the Finnish type (CNF); and in normal kidney tissue. In particular, we examined whether an association exists between synaptopodin expression in podocyte cells and the response to steroids in INS, and whether synaptopodin expression can predict FSGS upon the initial kidney biopsy in children who progress from MCD or DMH …
