Lymphadenopathy is one of the commonest and significant manifestations of local as well as systemic ailments, especially malignancies. Fine needle aspiration cytology (FNAC) helps in diagnosing the disease itself, in general, but more importantly ruling out malignancy, in particular. Hence it saves much of the cost and use of resources incurred with excision biopsy of such lymph nodes. This prompted us to study the cytologic patterns of lymphadenopathy in our setting and the diagnostic utility of FNAC in the evaluation of lymphadenopathy. In this retrospective observational study, 1,579 patients (953 males and 626 females) with lymphadenopathy who were subjected to FNAC over a period of three years (January 2009 to December 2011) were studied. The cervical region was involved in most of the cases (76%) followed by the axillary region (17.5%). Metastatic malignancy (38.2%) was the commonest cause of lymphadenopathy followed by reactive lymphoid hyperplasia (36.9%), tuberculosis (9.1%) and lymphomas (8.6%). Squamous cell carcinoma (32.2%) followed by adenocarcinoma (21.9%) were the most frequent metastatic tumors. FNAC is a useful diagnostic tool in the management of patients presenting with lymphadenopathy and should be considered before more invasive and costly procedures are performed, particularly in developing countries.

<P>Cyclobenzaprine hydrochloride (CBH) is a well-known muscle relaxant that is widely used to relieve muscle spasms and other pain associated with acute musculoskeletal conditions. In this study, we elucidated the binding characteristics of this muscle relaxant to human serum albumin (HSA). From a pharmaceutical and biochemical viewpoint, insight into the structure, functions, dynamics, and features of HSA-CBH complex holds great importance. The binding of CBH with this major circulatory transport protein was studied using a combination of biophysical approaches such as UV-VIS absorption, fluorescence quenching, and circular dichroism (CD) spectroscopy. Various <I>in silico</I> techniques, molecular docking and molecular dynamics, were also used to gain deeper insight into the binding. A reduction in the fluorescence intensities of HSA-CBH complex with a constant increase in temperature, revealed the static mode of protein fluorescence quenching upon CBH addition, which confirmed the formation of the HSA-CBH ground state complex. The alteration in the UV-VIS and far-UV CD spectrum indicated changes in both secondary and tertiary structures of HSA upon binding of CBH, further proving CBH binding to HSA. The analysis of thermodynamic parameters ∆H° and ∆S° showed that binding of CBH to HSA was dominated by intermolecular hydrophobic forces. The results of the molecular docking and molecular dynamics simulation studies also confirmed the stability of the complex and supported the experimental results.</P>

Qadri, Sumyra Khurshid,Hamdani, Nissar Hussain,Shah, Parveen,Baba, Khalil Mohammad Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.1
Background: Lymphadenopathy is a common presentation in both benign and malignant diseases which need to be diagnosed without delay. Fine needle aspiration cytology (FNAC) helps us diagnose a disease and follow its course, including the response to therapy. Aim: This study aimed to analyze the clinicopathological features of metastatic lymphadenopathy and the diagnostic utility of FNAC in our setting. Materials and Methods: This two-year prospective study included all the patients with metastatic lymphadenopathy, diagnosed with FNAC. Results: A total of 412 cases (male:female ratio, 1.3:1; age range, 3 to 90 years) were studied. Supraclavicular lymph nodes were involved most commonly (50.5%). The commonest metastatic tumor was squamous cell carcinoma in general (30.1%) and in males (37.6%), and infiltrating ductal carcinoma (25.3%) in females. Lung, with 64 (15.5%) cases followed by esophagus, 60 (14.6%) cases; breast, 49 (11.9%) cases; skin, 32 (7.8%) cases; and stomach, 25 (6.1%) cases were the most common primary sites of malignancy. In 69 patients, excision biopsy was performed. Histopathological findings correlated well with that of cytology in all these cases. Conclusions: FNAC is an important tool in the diagnostic work up of metastatic lymphadenopathy, which in the hands of an experienced and skilful cytopathologist can avoid the need for excision biopsy.

Background: Proteases play a regulatory role in a variety of pathologies including cancer, pancreatitis, thromboembolic disorders, viral infections and many others. One of the possible strategies to combat these pathologies seems to be the use of protease inhibitors. LC-pi I, II, III and IV (Lavatera cashmerian-protease inhibitors) have been found in vitro to strongly inhibit trypsin, chymotrypsin and elastase, proteases contributing to tumour invasion and metastasis, indicated possible anticancer effects. The purpose of this study was to check in vitro anticancer activity of these four inhibitors on human lung cancer cell lines. Material and Methods: In order to assess whether these inhibitors induced in vitro cytoxicity, SRB assay was conducted with THP-1 (leukemia), NCIH322 (lung) and Colo205, HCT-116 (colon) lines. Results: LC-pi I significantly inhibited the cell proliferation of all cells tested and also LC-pi II was active in all except HCT-116. Inhibition of cell growth by LC-pi III and IV was negligible. $IC_{50}$ values of LC-pi I and II for NCIH322, were less compared to other cell lines suggesting that lung cancer cells are more inhibited. Conclusion: These investigations might point to future preventive as well as curative solutions using plant protease inhibitors for various cancers, especially in the lung, hence warranting their further investigation.

Shaikh, Muhammad Shariq,Adil, Salman Naseem,Shaikh, Mohammad Usman,Khurshid, Mohammad Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.21
Background: The difference in prognosis of adult and childhood acute lymphoblastic leukemia (ALL) can be attributed largely to variation in cytogenetic abnormalities with age groups. Cytogenetic analysis in acute leukemia is now routinely used to assist patient management, particularly in terms of diagnosis, disease monitoring, prognosis and risk stratification. Knowing about cytogenetic profile at the time of diagnosis is important in order to take critical decisions in management of the patients. Aim and Objectives: To determine the frequency of cytogenetic abnormalities in Pakistani adult patients with ALL in order to have insights regarding behavior of the disease. Materials and Methods: A retrospective analysis of all the cases of ALL (${\geq}15$years old) diagnosed at Aga Khan University from January 2006 to June 2014 was performed. Phenotype (B/T lineage) was confirmed in all cases by flow cytometry. Cytogenetic analysis was made for all cases using the trypsin-Giemsa banding technique. Karyotypes were interpreted using the International System for Human Cytogenetic Nomenclature (ISCN) criteria. Results: A total of 166 patients were diagnosed as ALL during the study period, of which 151 samples successfully yielded metaphase chromosomes. The male to female ratio was 3.4:1. The majority (n=120, 72.3%) had a B-cell phenotype. A normal karyotype was present in 51% (n=77) of the cases whereas 49% (n=74) had an abnormal karyotype. Of the abnormal cases, 10% showed Philadelphia chromosome; t(9;22)(q34;q11.2). Other poor prognostic cytogenetic subgroups were t(4;11)(q21;q23), hypodiploidy (35-45 chromosomes) and complex karyotype. Hyperdiploidy (47-57 chromosomes) occurred in 6.6%; all of whom were younger than 30 years. Conclusions: This study showed a relatively low prevalence of Philadelphia chromosome in Pakistani adults with ALL with an increase in frequency with age (p=0.003). The cumulative prevalence of Philadelphianegative poor cytogenetic aberrations in different age groups was not significant (p=0.6).

Shaikh, Muhammad Shariq,Ali, Syed Sarwer,Khurshid, Mohammad,Fadoo, Zehra Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.9
Background: Cytogenetic abnormalities have important implications in diagnosis and prognosis of acute leukemia and are now considered an important part of the diagnostic workup at presentation. Karyotype, if known at the time of diagnosis, guides physicians to plan appropriate management strategies for their patients. Aim and Objectives: To determine the cytogenetic profile of acute lymphoblastic leukemia (ALL) in Pakistani children in order to have insights regarding behavior of the disease. Materials and Methods: A retrospective analysis of all the cases of ALL (<15years old) diagnosed at Aga Khan University from January 2006 to June 2011 was performed. Cytogenetic analysis was made for all cases using the trypsin-Giemsa banding technique. Karyotypes were interpreted using the International System for Human Cytogenetic Nomenclature (ISCN) criteria. Results: A total of 153 patients were diagnosed as ALL during the study period, of which 127 samples successfully yielded metaphase chromosomes. The male to female ratio was 1.8:1. A normal karyotype was present in 51.2% (n=65) of the cases whereas 48.8% (n=62) had an abnormal karyotype. Most of the abnormal cases showed hyperdiploidy(13.4%) followed by t(9;22)(q34;q11.2) (7.08%). Conclusions: This study revealed a relative lack of good prognostic cytogenetic aberrations in Pakistani children with ALL.
