CASTLEMAN DISEASE: A GREAT MIMICKER OF METASTASES IN RADIOIODINE REFRACTORY THYROID CANCER
A 27-year-old male underwent total thyroidectomy for thyroid swelling. Histopathology showed papillary thyroid carcinoma [T3 - 6.0 cm] with extra-thyroidal extension. The patient was treated with 150 mCi radioactive iodine(RAI) as adjuvant ablative therapy. Radioiodine refractory disease was identified 1-year post-RAI therapy with elevated thyroglobulin levels and negative I-131 whole body scan. F-18 FDG positron emission tomography/computedtomography scan showed activity in the right thyroid bed and multilevel right cervical nodes. Right-sided modified neck dissection was done, which showed Castleman disease (hyaline vascular type) in right cervical nodes. The most probable cause of elevated tumour markers was found out to be 0.6 cm right thyroid bed nodule on follow-up ultrasonography. Our patient also had coexistent conditions as; osteopoikilosis and Hepatitis C along with thyroid carcinoma.Key words: Castleman disease, lymph node, radioiodine, thyroid cance
Glyphosate: cancerous or not? Perspectives from both ends of the debate
Glyphosate is non-selective herbicide. Studies published in the last decade, point towards glyphosate toxicity. Shikimic acid pathway for the biosynthesis of folates and aromatic amino acids is inhibited by glyphosate. Glyphosate carcinogenicity is still considered to be a controversial issue. The World Health Organizations’ International Agency recently concluded that glyphosate is “probably carcinogenic to humans.” Some researchers believed that glyphosate is not linked with carcinogenicity
What can motivate Lady Health Workers in Pakistan to engage more actively in tuberculosis case-finding?
BACKGROUND: Many interventions to motivate community health workers to perform better rely on financial incentives, even though it is not clear that monetary gain is the main motivational driver. In Pakistan, Lady Health Workers (LHW) are responsible for delivering community level primary healthcare, focusing on rural and urban slum populations. There is interest in introducing large-scale interventions to motivate LHW to be more actively involved in improving tuberculosis case-finding, which is low in Pakistan. METHODS: Our study investigated how to most effectively motivate LHW to engage more actively in tuberculosis case-finding. The study was embedded within a pilot intervention that provided financial and other incentives to LHW who refer the highest number of tuberculosis cases in three districts in Sindh province. We conducted semi-structured interviews with 20 LHW and 12 health programme managers and analysed these using a framework categorising internal and external sources of motivation. RESULTS: Internal drivers of motivation, such as religious rewards and social recognition, were salient in our study setting. While monetary gain was identified as a motivator by all interviewees, programme managers expressed concerns about financial sustainability, and LHW indicated that financial incentives were less important than other sources of motivation. LHW emphasised that they typically used financial incentives provided to cover patient transport costs to health facilities, and therefore financial incentives were usually not perceived as rewards for their performance. CONCLUSIONS: This study indicated that interventions in addition to, or instead of, financial incentives could be used to increase LHW engagement in tuberculosis case-finding. Our finding about the strong role of internal motivation (intrinsic, religious) in Pakistan suggests that developing context-specific strategies that tap into internal motivation could allow infectious disease control programmes to improve engagement of community health workers without being dependent on funding for financial incentives
Loss-to-follow-up and delay to treatment initiation in Pakistan's national tuberculosis control programme
BACKGROUND: Researchers and policy-makers have identified loss to follow-up as a major programmatic problem. Therefore, the objective of this study is to quantify TB related pre-treatment loss to follow up and treatment delay in private sector health care facilities in Pakistan.
METHODS: This was a retrospective, descriptive cohort study using routinely collected programmatic data from TB referral, diagnosis and treatment registers. Data from 48 private healthcare facilities were collected using an online questionnaire prepared in ODK Collect, for the period October 2015 to March 2016. Data were analysed using SPSS. We calculated the: (1) number and proportion of patients who were lost to follow-up during the diagnostic period, (2) number and proportion of patients with pre-treatment loss to follow-up, and (3) the number of days between diagnosis and initiation of treatment.
RESULTS: One thousand five hundred ninety-six persons with presumptive TB were referred to the laboratory. Of these, 96% (n = 1538) submitted an on-the-spot sputum sample. Of the 1538 people, 1462 (95%) people subsequently visited the laboratory to submit the early morning (i.e. the second) sample. Hence, loss to follow-up during the diagnostic process was 8% overall (n = 134). Of the 1462 people who submitted both sputum samples, 243 (17%) were diagnosed with sputum smear-positive pulmonary TB and 231 were registered for anti-TB treatment, hence, loss in the pre-treatment phase was 4.9% (n = 12). 152 persons with TB (66%) initiated TB treatment either on the day of TB diagnosis or the next day. A further 79 persons with TB (34%) commenced TB treatment within a mean time of 7 days (range 2 to 64 days).
CONCLUSION: Concentrated efforts should be made by the National TB Control Programme to retain TB patients and innovative methods such as text reminders and behavior change communication may need to be used and tested

Community Knowledge about Tuberculosis and Perception about Tuberculosis-Associated Stigma in Pakistan
Tuberculosis- (TB) associated stigma is a well-documented phenomenon with various factors, both individual and societal, manifesting its role in shaping health-seeking behavior and contributing to suboptimal TB care in Pakistan. The objective of this study was to assess TB-related knowledge and perceived stigma among community members. This was a cross-sectional survey using a convenience sample of 183 individuals recruited between October and December 2017. A validated stigma measurement tool developed by Van Rie et al. was adapted. Data was analyzed using SPSS version 20.0. A clear majority was aware that TB is curable disease and that it is transmitted by coughing. However, respondents also thought that TB spread through contaminated food, sharing meals, sharing utensils, and by having sexual intercourse with a TB patient. In addition, females, unemployed, and persons having less than six years of education were also more likely to associate stigma with TB. We found an association between the lack of knowledge about TB and perceived stigma. This study highlights the need for improved TB-related education among communities
Efficient Adsorption of Lead Ions from Synthetic Wastewater Using Agrowaste-Based Mixed Biomass (Potato Peels and Banana Peels)
The aquatic environment is continuously being polluted by heavy metals released from industrial, domestic, agricultural, and medical applications. It is difficult to remove heavy metals, as they are nonbiodegradable. Heavy metals cause genotoxicity and serious carcinogenic disorders. Various conventional methods have been used for the removal of heavy metals, but these are time-consuming and not economical, so green methods, being economical, are preferred over conventional methods. Adsorption, being effective, environmentally friendly, and cheap, is often preferred. The present investigation investigated the adsorption efficiency of agrowaste-based biosorbents for removal of Pb(II) ion from the synthetic wastewater. Mixed biomass of banana peel and potato peels was used to create biosorbents. The biosorbents were characterized in terms of structural and surface morphology by SEM, while functional groups were analyzed by FT-IR and XRD analysis. The adsorption of Pb(II) was studied by a batch method, and various experimental parameters were studied. Optimum conditions for the removal of lead were pH = 5, concentration = 10 ppm, adsorbent dosage = 1.0 g, and contact time = 2 h. Kinetic modelling studies showed that the adsorption of Pb(II) ions followed a pseudo-second-order mechanism, and the Langmuir isotherm model was found to fit well for this study. Highlights: Synthesis of biosorbents (mixed biomass of potato peel and banana peel, biochar, TiO2 nanocomposites). Characterization of prepared biosorbents (SEM, XRD, FT-IR). Optimized parameters (pH, initial concentration, adsorbent dosage, and contact time) for removal of pollutant
