Department of Pathology and Laboratory Medicine

To investigate the potential functional cooperation between p27Kip1 and p130 in vivo, we generated mice deficient for both p27Kip1 and p130. In p27Kip1−/−;p130−/− mice, the cellularity of the spleens but not the thymi is significantly increased compared with that of their p27Kip1−/− counterparts, affecting the lymphoid, erythroid, and myeloid compartments. In vivo cell proliferation is significantly augmented in the B and T cells, monocytes, macrophages, and erythroid progenitors in the spleens of p27Kip1−/−; p130−/− animals. Immunoprecipitation and immunodepletion studies indicate that p130 can compensate for the absence …


Socio-Demographic Correlates Of Betel, Areca And Smokeless Tobacco Use As A High Risk Behavior For Head And Neck Cancers In A Squatter Settlement Of Karachi, Pakistan, Samia Mazahir, Rabia Malik, Maria Maqsood, Kanwal Aliraza Merchant, Farida Malik, Atif Majeed, Zafar Fatmi, Muhammad Rizwanulhaq Khawaja, Shehzad Ghaffar Apr 2006

Community Health Sciences

Background

Head and neck cancers are a major cancer burden in Pakistan. They share a common risk factor profile including regular consumption of products of betel, areca and tobacco. Use of paan, chaalia, gutka, niswar and tumbaku is acceptable in Pakistan and is considered a normal cultural practice. This cross-sectional study was carried out to understand the relation of socio-demographic factors for the consumption of paan, chaalia, gutka, niswar and tumbaku in Pakistani population. Through systematic sampling, 425 subjects from a squatter settlement in Karachi were interviewed using a structured questionnaire. High risk behavior was defined as Daily use of …


Racial Disparity And Socioeconomic Status In Association With Survival In Older Men With Local/Regional Stage Prostate Cancer: Findings From A Large Community-Based Cohort, Xianglin L.

CRVAW Faculty Journal Articles

BACKGROUND

Few studies have examined the outcomes for Hispanic men with prostate carcinoma and incorporated socioeconomic factors in association with race/ethnicity in affecting survival, adjusting for factors on cancer stage, grade, comorbidity, and treatment.

METHODS

We studied a population-based cohort of 61,228 men diagnosed with local or regional stage prostate carcinoma at age 65 years or older between 1992 and 1999 in the 11 SEER (Surveillance, Epidemiology, and End Results) areas, identified from the SEER-Medicare linked data with up to 11 years of followup.

RESULTS

Low socioeconomic status was significantly associated with decreasing survival in all men with prostate carcinoma. …


Follicular Dendritic Cell Sarcoma Of Lymph Node - A Rare Entity, Safoorah Khalid, Nausheen Yaqoob, Shahid Pervez Mar 2006

Follicular Dendritic Cell Sarcoma Of Lymph Node - A Rare Entity, Safoorah Khalid, Nausheen Yaqoob, Shahid Pervez

Department of Pathology and Laboratory Medicine

Follicular dendritic cells (FDC) are non-lymphoid, non-phagocytic accessory cells in the immune system that are essential for antigen presentation and germinal center reaction regulation1. These cells are CD21+, CD35+, CD1a- and S100 protein + and they show desmosomes ultrastructurally.

The most commonly involved sites by FDC tumors are lymph nodes but may arise at a variety of extranodal sites including oral cavity, tonsil, gastrointestinal tract and liver. Most studies represent single case reports or case series.

Our patient presented with tumor in the lymph nodes. Histology revealed tumor cells with abundant eosinophilic cytoplasm, hyperchromatic and pleomorphic nuclei, and prominent nucleoli. …


Uterine Perivascular Epithelioid Cell Tumour Presenting As A Cervical Mass, Najamul Sahar Azad, Shahid Pervez, Naila Kayani, Aliya Begum Aziz Feb 2006

Uterine Perivascular Epithelioid Cell Tumour Presenting As A Cervical Mass, Najamul Sahar Azad, Shahid Pervez, Naila Kayani, Aliya Begum Aziz

Department of Pathology and Laboratory Medicine

Perivascular Epithelioid Cell Tumour (PEComa) also known as myelomelanocytic tumours are uncommon, recently described mesenchymal tumours that include angiomyolipoma, clear cell "sugar" tumour of the lung, lymphangioleiomyoma and tumours composed predominantly of epithelioid cell morphology. A predilection for uterus has been described. However up till now only 14 cases of uterine PEComas have been described. All of these were seen in adult females in the peri and post menopausal age group (from 40-75years), and almost all were located in the region of body of uterus. A single case in the upper cervical region has been reported with uterine PEComatoses. We …


Maternal And Fetal Complications Of Antiphospholipid Syndrome: A Case Report With Long-Term Follow-Up, Tahira Naru, Mohammad Khurshid, Zafar Nazir Feb 2006

Maternal And Fetal Complications Of Antiphospholipid Syndrome: A Case Report With Long-Term Follow-Up, Tahira Naru, Mohammad Khurshid, Zafar Nazir

Department of Obstetrics & Gynaecology

We report a case of a 26- year old woman having antiphospholipid syndrome in pregnancy with long-term follow up. She presented with recurrent miscarriages, venous thrombosis, avascular necrosis of femoral head, mid-cerebral artery infarction and skin ulcers. Antiphospholipid syndrome is a recognized disorder of pregnancy. Diagnosis requires a high index of suspicion when evaluating women with recurrent pregnancy losses and vascular thrombosis. A low dose aspirin combined with heparin can reduce morbidity and improves the pregnancy outcome.

Cervical Cancer Survival By Socioeconomic Status, Race/Ethnicity, And Place Of Residence In Texas, 1995–2001, Katherine S. Eggleston, Ann L. Coker, Melanie Williams, Guillermo Tortolero-Luna, Jeanne B. Martin, Susan R. Tortolero Jan 2006

Cervical Cancer Survival By Socioeconomic Status, Race/Ethnicity, And Place Of Residence In Texas, 1995–2001, Katherine S. Eggleston, Ann L. Coker, Melanie Williams, Guillermo Tortolero-Luna, Jeanne B. Martin, Susan R. Tortolero

CRVAW Faculty Journal Articles

Objective: The current study explored whether socioeconomic status (SES), race/ethnicity, and rural residence may be linked to poorer cervical cancer survival by stage at diagnosis.

Methods: Data from 7,237 cervical cancer cases reported to the Texas Cancer Registry from 1995–2001 were used to address the association by stage at diagnosis and cause of death. Zip code-level census data were used to classify residence and to develop a composite variable for SES. Multilevel Cox proportional hazards modeling was used to estimate hazard ratios

(HR) and 95% confidence intervals (CI).

Results: Late stage at diagnosis was a strong predictor …
