ABSTRACT
In India, there is 62% out-of-pocket health expenditure per capita and only 15% are covered by health insurance. The use of generics can save a lot of money which can be used for other health issues. But lack of knowledge about cost effectiveness of generic medicines among various health-care professionals had led to a low rate of generic medicine prescription in India. This review aims to identify the barriers in adoption of generic prescribing in clinical practice in India. A systematic literature review was conducted using various healthcare databases such as PubMed and google scholar. The literature search using various combination of keywords retrieved 2360 articles. After excluding duplicates, articles in languages other than English and based on relevance to subject only 15 articles were selected. The barriers to generic prescribing identified from reported literature can be broadly classified based on stakeholders of healthcare setting such as physicians, patients, pharmacist and government policies. The major barriers to generic prescribing identified were negative perception of various stakeholders, lack of awareness of regulatory standards, maturity of health care system, vulnerability of patients, lack of standard guidelines in brand substitution, incentives and influence of drug advertisements. In Indian set up, studies on impact evaluation of generic prescription, emphasizing the quality and cost saving by their use in clinical practice should be conducted. This evidence will help to build the confidence of various stakeholders towards implementing generic prescribing in clinical practice.
ABSTRACT
The aim of present study was to evaluate the linkage disequilibrium (LD) of p.R72P, PIN3 Ins16bp, p.P47S, p.R213R and r.13494g[a polymorphism of TP53 and their haplotypes association with oesophageal cancer risk in patients from Punjab, northwest India. A total of 466 samples, including 233 oesophageal cancer patients and 233 healthy individuals were analysed. Data analysis revealed the gender specific association. In female group, arginine–proline (RP) genotype (P = 0.08) and P allele (P = 0.07) of p.R72P polymorphism was marginally associated with increased risk of oesophageal cancer. A1A2 genotype (P = 0.06) and A2 allele (P = 0.07) of PIN3 Ins16bp polymorphism was marginally associated with decreased risk of oesophageal cancer in male group. A1A2–GA genotype combination (P = 0.04) of PIN3 and r.13494g[a polymorphisms was significantly associated with decreased risk of oesophageal cancer in male group. In female group, PP–GA genotype combination (P = 0.02) of p.R72P and r.13494g[a polymorphisms and RP–A1A1–GG genotype combination (P = 0.04) of p.R72P, PIN3 and r.13494g[a polymorphisms was significantly associated with increased risk of oesophageal cancer. We observed moderate LD between two intronic polymorphisms PIN3 Ins16bp and r.13494g[a (D0 = 0.90; r 2 = 0.68). Haplotype analysis revealed that none of the haplotype combination was associated with oesophageal cancer risk when both the genders were considered. Stratification on the basis of gender showed that P-A2-P-A-A haplotype of p.R72P, PIN3 Ins16bp, p.P47S, p.R213R and r.13494g[a polymorphisms was marginally associated with reduced oesophageal cancer risk in male group (P = 0.08). Replication of these findings in independent cohorts may be insightful for the role of TP53 in oesophageal cancer pathogenesis.
ABSTRACT
BACKGROUND: Non-urothelial bladder tumors (NUBTs) are uncommon accounting for approximately 10% of the total urinary bladder tumors while 90% are urothelial in origin. There are very limited comprehensive studies on NUBTs. AIMS AND OBJECTIVES: The objectives of the study were to analyze the clinicopathological and immunohistochemical features of NUBTs. MATERIALS AND METHODS: This is a retrospective study of NUBTs diagnosed over a period of 9 years. Patients' files were retrieved from the archives. Gross and microscopic features were recorded. Simple percentage and frequencies were used to interpret the data. RESULTS: A total 16 cases (10.8% of all bladder tumors) of NUBT were found. Patients' ages ranged from 19 to 87 years with a male: female ratio of 4.3:1. The most common presenting symptom was gross hematuria (81.2%), and the most common location was posterolateral bladder wall. Muscle invasion was seen in 81.2% of cases, and large areas of necrosis were observed in 62.5%. There were two cases of squamous cell carcinoma, five cases each of adenocarcinoma (four secondary and one urachal) and mesenchymal tumors (four malignant and one benign), two cases of amyloid, and one case each of plasmacytomas and paraganglioma. Large areas of necrosis and muscle invasion were noted in high-grade and advanced staged tumors. In all, 43.7% had poor survival. CONCLUSION: NUBTs present with similar clinicoradiological findings; however, their histological features along with immunohistochemistry help in the definite diagnosis. One should be aware of these tumors as they frequently present diagnostic and therapeutic challenge. Most of these neoplasms present at an advanced stage. Large or multicentric randomized controlled studies are needed to know the exact behavior and prognosis of these tumors.
ABSTRACT
The present study was carried out to assess food and foraging niches of carnivorous bird species in mixed fruit orchard selecting two transects I and II at Punjab Agricultural University campus from March 2015 to February 2016. There were observed 12 and 11 carnivorous bird species out of total 52 and 38 bird species recorded in transect I and II respectively. Habitat features (hedgerows, un-cemented water channel), irrigation schedules and fruit developmental stages seemed to determine the bird composition, especially carnivorous bird species in mixed fruit orchard
ABSTRACT
BACKGROUND: Hemangiopericytomas (HPCs) and solitary fibrous tumors (SFTs) are unique entities in the central nervous system (CNS) and even rarer in the spine with propensity to recurrence and metastasis. Both these tumors were detected to share the NAB2–STAT6 fusion gene with frequent morphologic overlap that necessitated the need for the combined term SFT/HPC in the CNS by the World Health Organization (WHO) in 2016. AIMS: This study aims to describe the clinical outcome of intracranial and spinal SFT/HPCs based on detailed histomorphologic and immunohistochemical features. MATERIALS AND METHODS: A retrospective analysis of these tumors was conducted over a period of 10 years from January 2006 to January 2017 at our institute. Based on the elaborative assessment of morphology and immunohistochemistry, these tumors were categorized into three grades as per WHO criteria. RESULTS: A total of 13 cases were encountered involving mainly extra-axial and supratentorial regions. Among intracranial HPCs, anaplastic subtypes constituted significantly higher proportion (39%) when compared with peripheral HPCs. Peculiar morphological patterns like micropapillae and pseudoangiomatous arrangement of tumor cells were observed in high-grade tumors. A panel of immunomarkers were used to confirm the diagnosis and rule out other mimickers. Gross total resection was achieved in 54% (7/13) of the cases with local recurrence observed in 31% (4/13). Grade II tumors showed recurrence in 28% cases. No case showed distant metastasis. CONCLUSION: To conclude, not just clinical parameters but morphologic features such as unusual patterns, mitosis, and proliferative index also play a pivotal role in predicting the clinical behaviour of SFT/HPC.
ABSTRACT
Splenic lymphoma with villous lymphocytes (SLVL) is a rare disorder that comprises less than 1% of lymphoid neoplasms. It is the leukemic counterpart of splenic marginal zone lymphoma (SMZL) and is characterized by splenomegaly, often with no lymphadenopathy, moderate lymphocytosis and villous lymphocytes on peripheral blood smear. Here, we report a case of SLVL in a 56-year-old male with very high leukocyte counts, massive splenomegaly and relatively few leukemic cells with subtle villous projections on the surface. This disorder is often confused with other chronic lymphoproliferative disorders, especially chronic lymphocytic leukemia (CLL) and hairy cell leukemia and should be differentiated from them. We are reporting this case to highlight the diagnostic pitfalls associated with this disorder.
