A rare case of medullary carcinoma thyroid metastasizing to bilateral breast parenchyma

Medullary carcinoma of the thyroid (MTC) commonly spreads through the lymphatics to distant sites such as lung, liver and bone. Spread to the breast is rare. We report a case of metastatic MTC which progressed to develop nodal metastases to cer­vical and mediastinal regions, visceral metastases to the liver, lung and ultimately to bilateral breasts. Clinically it is important to distinguish metastatic breast lesions from primary breast cancer as each is managed differently. Both cytological and radio­logical investigations were done followed by excision biopsy. Histopathological examination of post excision breast specimen revealed metastatic medullary carcinoma, with positive immunohistochemical staining for calcitonin. A brief review of literature and differential diagnosis is also presented

An audit of clinical laboratory data of 25OHD at Aga Khan University as reflecting Vitamin D deficiency in Pakistan

Objectives: To estimate the burden of Vitamin D deficiency in people from different geographical areas of Pakistan. Methods: The retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised specimens of subjects tested for 25-hydroxy D at the clinical laboratory between September 2010 and September 2011. Serum samples received from the phlebotomy centres all over Pakistan and the main laboratory in Karachi were included. SPSS 19 was used for statistical analysis. Results: Of the 60937 specimens in the study, 18721(30.7%) related to men. The overall mean age was 40.5±19.7 years, and median 25-hydroxy D level was 13.5ng/ml (interquartile range: 25.1-7.4 ng/ml).Overall, mean log 25-hydroxy D was 1.14±0.39ng/ml (median: 13.5ng/ml; interquartile range: 25.1-7.4 ng/ml). Out of the total, 40279(66.1%) subjects were vitamin D-deficient

Focused Ion Beam Tomography

To study the fundamental effect of shape and morphology of any material on its properties, it is very essential to know and study its morphology. Focused ion beam (FIB) tomography is a 3D chemical and structural relationship studying technique. The instrumentation of FIB looks like that of the scanning electron microscopy (SEM), but there is a major difference in the beam used for scanning. For SEM, a beam of electrons is used with scanning medium whereas in FIB, a much focused beam of ions is used for scanning. FIB can be used for lithography and ablation purposes, but due to advancements and high-energy focused beam, it is nowadays being used as a tomographic technique. Tomography is defined as imaging by sectoring or cross-sectioning any desired area. The hyphenation of FIB with energy-dispersive spectrometry or secondary ion mass spectrometry can give us elemental analysis with very high-resolution 3D images for a sample. This technique contributes to acquaintance of qualitative and quantitative analyses, 3D volume creations, and image processing. In this chapter, we will discuss the advancements in FIB instrumentation and its use as 3D imaging tool for different samples ranging from nanometer (nm)-sized materials to micrometer (μm)-sized biological samples

Quality of Life in Children with Epilepsy in Wah Cantt, Pakistan: A Cross-sectional Study

Objective: To assess the Quality Of Life (QOL) in children with epilepsy using modified QOLCE-55 questionnaire. Material and Methods: We consecutively enrolled children aged 4 to 16 years who were under treatment for childhood epilepsy. Basic demographic and clinical details including type of epilepsy, developmental history, family history of epilepsy and any co-morbidity were recorded in a predesigned Performa. QOL was evaluated by using modified QOLCE-55 (39 items) from parents. Results: A total of 54 children were enrolled in the study, 42 (78%) were males and 12(22%) were female children with epilepsy.  Eight children got good QOLCE score, while 24 children had average and 22 children got a poor score. The good score was mostly seen in 4-8 years (40%) of age while the poor score was seen in 12-16 years (70%) age group. Age of the patients (p=<0.001), gender (p=<0.001), associated co-morbidities (p=0.003) and family history of epilepsy (p=0.011) showed a significant effect on the QOLCE score. Type of epilepsy (p= 0.825) and development of a child (p=0.109) did not affect the QOLCE score significantly. Conclusion: The study showed that Children with co-morbidities, family history of epilepsy and female children of older age group (12-16 years) had poor QOL. Types of seizures and development of the child did not significantly alter the QOLCE score

Preliminary structure-activity relationship studies on some novel s-substituted aliphatic analogues of 5-{1-[(4- chlorophenyl) sulfonyl]-3-piperidinyl}-1, 3, 4-oxadiazol-2-yl sulfide

Purpose: To study the structure-activity relationships of synthetic multifunctional sulfides through evaluation of lipoxygenase and anti-bacterial activities.Methods: S-substituted derivatives of the parent compound 5-(1-(4- chlorophenylsulfonyl) piperidin-3- yl)-1, 3, 4-oxadiazole-2-thiol were synthesized through reaction with different saturated and unsaturated alkyl halides in DMF medium, with NaH catalyst. Spectral characterization of each derivative was carried out with respect to IR, 1H - NMR, 13C - NMR and EI - MS. The lipoxygenase inhibitory and antibacterial activities of the derivatives were determined using standard procedures.Results: Compound 5e exhibited higher lipoxygenase inhibitory potential than the standard (Baicalein®), with % inhibition of 94.71 ± 0.45 and IC50 of 20.72 ± 0.34 μmoles/L. Compound 5b showed significant antibacterial potential against all the bacterial strains with % inhibition ranging from 62.04 ± 2.78, 69.49 ± 0.41, 63.38 ± 1.97 and 59.70 ± 3.70 to 78.32 ± 0.41, while MIC ranged from 8.18 ± 2.00, 10.60 ± 1.83, 10.84 ± 3.00, 9.81 ± 1.86 and 11.73 ± 5.00 μmoles/L for S. typhi, E. coli, P. aeruginosa, B. subtilis and S. aureus, respectively. Compounds 5d, 5e and 5g showed good antibacterial activity against S. typhi and B. subtilis bacterial strains.Conclusion: The results suggest that compound 5e bearing n-pentyl group is a potent lipoxygenase inhibitor, while compound 5b with n-propyl substitution is a strong antibacterial agent. In addition, compounds 5d, 5e and 5g bearing n-butyl, n-pentyl and n-octyl groups, respectively, are good antibacterial agents against S. typhi and B. subtilis.Keywords: Sulfides, Antibacterial activity, Lipoxygenase activity, Spectral analysi

Inhibition of full length Hepatitis C Virus particles of 1a genotype through small interference RNA

<p>Abstract</p> <p>Background</p> <p>Hepatitis C virus (HCV), a member of the <it>Flaviviridae </it>family of viruses, is a major cause of chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. Currently, the only treatment available consists of a combination of Pegylated interferon alpha (INF-α) and ribavirin, but only half of the patients treated show a sufficient antiviral response. Thus there is a great need for the development of new treatments for HCV infections. RNA interference (RNAi) represents a new promising approach to develop effective antiviral drugs and has been extremely effective against HCV infection.</p> <p>Results</p> <p>This study was design to assess or explore the silencing effect of small interference RNAs (siRNAs) against full length HCV particles of genotype 1a. In the present study six 21-bp siRNAs were designed against different regions of HCV structural genes (Core, E1 and E2). Selected siRNAs were labeled as Csi 301, Csi 29, E1si 52, E1si 192, E2si 86 and E2si 493. Our results demonstrated that siRNAs directed against HCV core gene showed 70% reduction in viral titer in HCV infected liver cells. Moreover, siRNAs against E1 and E2 envelop genes showed a dramatic reduction in HCV viral RNA, E2si 86 exhibited 93% inhibition, while E1si 192, E2si 493 and E1si 52 showed 87%, 80%, and 66% inhibition respectively. No significant inhibition was detected in cells transfected with the negative control siRNA.</p> <p>Conclusion</p> <p>Our results suggested that siRNAs targeted against HCV structural genes efficiently silence full length HCV particles and provide an effective therapeutic option against HCV infection.</p
