Squamous Cell Carcinoma in Exstrophy of the Bladder
Pramod Kumar Sharma,Praveen Kumar Pandey,Mukesh Kumar Vijay,Malay Kumar Bera,Jitendra Pratap Singh,Kaushik Saha 대한비뇨의학회 2013 Investigative and Clinical Urology Vol.54 No.8
Exstrophy of the bladder is a rare congenital anomaly with an incidence of about 1 per 50,000 newborns. The malignant potential of the exstrophied bladder mucosa is well known; 95% are adenocarcinomas, and 3% to 5% are squamous cell carcinomas. Most of the malignant tumors (60%) associated with an exstrophy of the bladder occur during the fourth and fifth decades of life. Of the remaining, about 20% each occur after 60 years and before 40 years. Here we present a case in which squamous cell carcinoma developed in an unrepaired exstrophy of the bladder. We present the management of the case and a brief review of the literature.

Praveen Sharma,Pramod Kumar Pal 대한파킨슨병및이상운동질환학회 2023 Journal Of Movement Disorders Vol.16 No.1
GTP cyclohydrolase-1 (GCH1)-deficient dystonia (DYT-GCH1/DYT5) is an autosomal-dominant dopa-responsive dystonia (DRD) of childhood onset typically presenting with foot dystonia progressing to generalized dystonia and parkinsonism with diurnal fluctuation and a dramatic and persistent response to levodopa (LD)

Impact of lymph node staging systems in predicting outcome in patients with ampullary cancer
Sundeep Singh Saluja,Pramod Kumar Mishra,Shashi Kiran,Harsh J. Shah,Sandip Chandrasekar,Mohammed Nayeem,Aditya Sharma,Vaibhav Kumar Varshney 한국간담췌외과학회 2020 Annals of hepato-biliary-pancreatic surgery Vol.24 No.4
Backgrounds/Aims: Lymph node (LN) metastasis though, is a poor prognostic factor for ampullary carcinoma (APC), the impact of Lymph node ratio (LNR) and Logarithm odds of positive lymph node (LODDS) in the long-term survival remains controversial. We evaluated the factors affecting the long-term outcome in APC patients with emphasis on LNR and LODDS. Methods: The prospectively collected data of 198 patients who underwent pancreatoduodenectomy for APC was analyzed after excluding 12 patients for various reasons. Factors affecting Disease specific survival (DSS) and Recurrence free survival (RFS) were analyzed with special reference to LN positivity, LNR and LODDS. Results: Out of 186, 117 (62.9%) patients were alive at a median follow-up of 39.5 months and 72 (38.7%) developed recurrence. The overall 5-year DSS was 59.3% & RFS 54.9%. Univariate analysis showed T-stage, tumor differentiation, perineural invasion, LN positivity, LNR and LODDS was significantly affected DSS and RFS. On multivariate analysis, perineural invasion, LN positivity, LNR and LODDS lost its significance for DSS and RFS. AUC for prediction of DSS and RFS for LNR was 0.654 (p<0.001) & 0.629 (p=0.003) respectively and for LODDS, it was 0.697 (p<0.001) & 0.677 (p=0.001) respectively. Sensitivity and specificity of LNR (0.1) for DSS were 37.7% & 83.8% and for RFS were 36.1% & 83.3%; for LODDS (−1.00), sensitivity and specificity for DSS was 62.3% and 67.5% and for RFS it was 59.7% and 66.7% respectively. Conclusions: LNR and LODDS although independently seem to affect the RFS and DSS, albeit have a low sensitivity and specificity in predicting DSS and RFS.

Graphene-based nanomaterial system: a boon in the era of smart nanocarriers
Jha Roopali,Singh Amit,Sharma Pramod Kumar,Porwal Omji,Fuloria Neeraj Kumar 한국약제학회 2021 Journal of Pharmaceutical Investigation Vol.51 No.3
Background Owing to its exceptional electronic, mechanical, thermal, as well as optoelectronic characteristics, graphene—a planar sheet with one-atom thickness and made of carbon atoms closely packed in quite a honeycomb crystal lattice—has already earned special consideration. The investigated characteristics or even applications of such a two-dimensional configuration of the structure of carbon have already created novel innovative opportunities in place of all of the future devices as well as nanosystems. Area covered These graphene systems have also been recognized as a potential drug-delivery carrier intended for target specific or even controlled drug delivery, which could be designed by utilizing various internal or external stimuli. Expert opinion This review predominantly focuses on graphene’s synthesis and derivative, design of stimuli-responsive nanosystems, and applications in various fields. It is highlighted that with remarkable progress in graphene-related research, graphene’s overall execution has a long road ahead to go.

Background: The effect of the interplay among inflammation, angiogenesis, extracellular matrix (ECM) degradation, and oxidative stress (OS) on the pathogenesis of endometriosis remains unclear. Previously, we demonstrated the role of OS in endometriosis. Here, we performed a comprehensive investigation of several molecules involved in inflammation, angiogenesis, and ECM degradation in women with endometriosis to study their interplay with OS. Methods: Blood samples were collected from women with endometriosis (N=80), as well as from women with tubal factor infertility as controls (N=80). Interleukin (IL)-1β, tumor necrosis factor-alpha, interferon-gamma, transforming growth factor-beta, IL-4, -10, -2, -6, -8, vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP)-2, -9, tissue inhibitor of metalloproteinases (TIMP)-1, -2, and cyclooxygenase (COX)-2 levels in serum samples were measured using an ELISA. Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) in peripheral blood mononuclear cells was measured using flow cytometry. Results: Cytokines, VEGF, MMPs, and COX-2 were significantly higher and TIMPs were significantly lower in patients with endometriosis. Multivariate statistical analysis indicated that IL-10 was the most significant variable capable of discriminating endometriosis samples from controls. Conclusions: Deregulation of NF-κB activation by OS affects the expression of various cytokines in endometriosis. Elevated cytokine levels further up-regulate IL-10, which subsequently activates the MMPs, leading to excessive ECM degradation and angiogenesis. Moreover, IL-10 emerged as the most important molecule involved in the pathogenesis of endometriosis. Measurement of these molecules may help in better management of the patients with endometriosis.

Burden of cancer is progressively increasing in developing countries like India which has also led to a steep rise in toxicity due to anti-cancer therapy. A cross-sectional analysis was here conducted for patients with different malignancies (except leukaemia) who while undergoing radical anti-cancer therapy were admitted to our oncology ward from January-July 2013. In a total of 280 patients, the total number of toxicity events was 473. Nine patients expired over this time period. Among the events, grade 2 anaemia the most common (n=189) while the most common grades of neutropenia and thrombocytopenia were grade 4 (n=114) and grade 2 (n=48), respectively. Among the tracable microbial etiologies, gram negative bacteria were the most commonly found pathogens. Treatment interruptions took place in 240 patients (median duration=8.8 days). Prolonged hospital admission, intensive care and artificial ventilation support was needed to be given in 48, 7 and 13 patients respectively. Advanced NSCLC, KPS <70, pancytopenia and artificial ventilation requirement were found to have a significant impact on death. Such studies show the prevailing practice from institutes of our country and may guide us formulating a guideline for managing such toxicities for this part of the world.
