Cardiac metastases from merkel cell cancer: A case report and review of literature

Published on: 5th July, 2022

OCLC Number/Unique Identifier: 9575034003

A 61 - year-old physically fit and athletic man presented to his dermatologist with a 10 mm raised, dark lesion on the left side of his neck. A complete skin examination did not show any other abnormal areas of skin. Pathology was found consistent with Merkel cell cancer, and the patient was referred to surgery for a wide local excision and sentinel lymph node biopsy. A PET scan did not show any other areas of concern. At surgery, one of two sentinel lymph nodes was found to be involved with Merkel cell cancer and the patient received postoperative radiation.

The forgotten player in the surgical history

Published on: 13th May, 2019

OCLC Number/Unique Identifier: 8164026356

The research concerning a preventive treatment of an osteoporitic femoral neck fracture started in 1990 because the surgical procedure of unstable femoral neck fractures is difficult. After effects are frequent and their number will increase in the next decade. The goal is to reinforce the femur with a biomaterial acting as a bone graft. Natural coral is bioresorbable and biocompatible. It acts as an autofocus bone graft for reconstruction of either cortex or cancellous bone and increases their mechanical resistance. This work shows evidence of new bone formation in an osteoporotic unbroken femoral neck femur. Consequently, the preventive surgical treatment of osteoporosis should be taken in consideration [1]. The purpose of this work is to show the results on the mineralization of the cancellous bone of an upper femoral metaphyses when a natural biomaterial is set in an unbroken osteoporotic femoral neck. Summary: Mrs. L is an 84 years old lady. Her osteoporotic unbroken right hip was grafted preventively with a biomaterial in order to prevent the high risk of break in case of fall. The biomaterial used is beads of natural coral. The reasons of this preventive treatment is discussed, as well as the choice of the biomaterial. The results are shown including a two years follow up. Brief History: Before going further, few words of history. Three centuries BC, an Aristote’s follower, Théophraste thinks that Natural coral is a petrified plant. For Ovide natural coral is a soft alga air-hardening. Al Biruni classes it among animals, because that respond to touch. At the beginning of the XVIIth century, Marsigli thinks that they are flowers which open out there in aquarium. The French Jean-André Peyssonnel, a young naturalist, says as Biruni, that in fact, corals are animals. At last, Buffon claims: These marine plants, were classified first in the rank of minerals, then in those of plants, and finally in that of animals. Natural coral is obviously an animal. After the Second World War, coral samples were analyzed by American scientists. Among 800 corail species, 3 where specially analyzed: Acropora, Porites and Libophylia. Mrs Nane Guillemin did in France her PHD on natural coral and with her team made a complete fundamental analysis (physical, chemical and biological properties) of the material, while the American scientists worked on the chemical bone’s properties. In France, Pr Ohayoun and his team worked on the surgical application in the dental field, Dr. Yves Cirotteau in the orthopedic surgery, specifically for osteoporotic disease and for the traumatologic field

Precision and personalized vaccines needed to face COVID-19 pandemic

Published on: 28th April, 2021

OCLC Number/Unique Identifier: 9028054428

Among the abounding lessons we learned from the SARS-C0V-2 pandemic is the uttermost determinant that people are not equal before the severity of COVID-19. Indeed, the disease course differs with age, gender, ethnicity, underlying clinical conditions and virus variants. Other diseases modifying factors are associated with genetic traits such as those driving the immune response, the blood groups, the coagulation system and the ACE2 receptor variants [1-4].

Association between clinical forms of Leprosy and contacts with the vaccination state with BCG in five endemic municipalities in the Brazilian Amazon

Published on: 19th July, 2022

OCLC Number/Unique Identifier: 9575035083

Introduction: The World Health Organization (WHO) strategy for leprosy control from 2021 to 2030 focuses on interrupting transmission, reducing autochthonous cases to zero, and using a safe and effective vaccine and chemoprophylaxis. In 2020, 127,396 new cases were registered in the world, 19,195 new cases in the Americas, and, of these, 17,979 cases in Brazil, about 93.66% of the total in the Americas. Brazil is classified as a country with a high burden of the disease, occupying the 2nd place in the world, behind only India (WHO, 2020). Análise do período de 2010-2015 em publicação recente9, apresenta as seguintes cidades no estado do Pará nas quais se observou maiores taxas de incidência (detecção): Marituba, Belém, Marabá, Parauapebas e Altamira [9]. Material and method: This is an analytical retrospective study carried out in a database - Epi-Info resulting from records of Surveillance and Seroprevalence actions in five endemic municipalities for leprosy located in the Southeast and West of Pará. The following variables were analyzed: age, sex, Clinical Classification, vaccination status with BCG, and the result of the search for IgM antibodies against PGL-1 of Mycobacterium leprae by the “In house” ELISA technique. Results: We evaluated 1551 records examined in the laboratory from 2014 to 2016, which were classified into 123 Multibacillary -MB patients (123/1551 = 7.93%); 71 Paucibacillary-PB patients (71/1551 = 4.57%); 451 Intradomicilliary Consanguineous Contacts - CCOSI (451/1551 = 29.07%) and 906 Non Consanguineous Contacts - CNCOS (906/1551 = 58.41%). 57 MB patients (13.47%), 13 PB patients (3.07%), 133 CCOSI (31.44%) and 220 CNCOS (52.00%) were positive for PGL-1. The correlation of the Classification with the vaccination status showed 57 MB patients without any BCG (57/125 = 45.6%) and only 3 patients with two doses of BCG (3/125 = 2.4%); 17 PB patients without any dose of BCG (17/69 = 24.63%); 80 CCOSI without any BCG (80/455 = 17.58%) and 171 CNCOS (171/906 = 18.87%). The odds ratio (OR) in the analysis between unvaccinated MB patients compared to CCOSI was statistically significant (OR = 14.25; p ˂ 0.0001). The study shows the importance of using the BCG vaccine in healthy contacts of patients with leprosy, as it shows the probability of unvaccinated individuals being 14.25 times more likely to become ill with Multibacillary forms compared to CCOSI. In addition, the BCG vaccine has been in use for 80 years and is the only vaccine that we can use in leprosy control programs. Conclusion: Although the leprosy epidemiological data analyzed recently (2010 - 2015) show a downward trend in the main indicators in Pará, such as the detection of new cases and prevalence, the endemic municipalities are still classified as hyperendemic for the population under 15 years of age and This proves that Surveillance is essential, as well as BCG vaccination according to the Ministry of Health Standards.

Atherogenic risk assessment of naive HIV-infected patients attending Infectious Diseases Service of Kinshasa University Teaching Hospital, Democratic Republic of the Congo (DRC)

Published on: 13th October, 2020

OCLC Number/Unique Identifier: 8689021635

Background and aim: Metabolic abnormalities are common in HIV/AIDS. Increasingly, lipid ratios are used as screening tools for dyslipidaemia in these medical conditions. The aim of this study was to assess the ability of 4 lipid ratios to predict cardiovascular risks. Methods: This is a cross-sectional and analytical study included 105 HIV+ patients followed in Kinshasa University Teaching Hospital (KUTH). Four indices [Atherogenic Index of Plasma (AIP), Castelli Risk Index (CRI) I and II, Atherogenic coefficient (AC)] were compared. Statistical analyzis consisted of measuring frequencies and means, Student’s t-tests, ANOVA and Ficher’s exact test, and the calculation of the Kappa value. Results: Lipid ratios predicted respectively the risk in 62% (AIP), 28.6% (CRI-I) and 23.8% (CRI-II). CRI-I and II were elevated, especially in women. The AIP appeared to be a better predictor than CRI-I and II to assess dyslipidaemia in general and the high-risk frequency. The cholesterol detected risk in 66.7% (Low HDL-C), 50% (High LDL-C), 38.9% (High TC and/or TG). The atherogenic risk was higher with age, advanced WHO stage, HIV-TB, HBV-HCV co-infections, smoking and alcohol intake. Haemoglobin (Hb) and CD4 counts were low when the risk was high. Age ≥ 50 years, stage 4 (WHO), CD4s+ ≤ 200 cells/µL were independent factors associated with atherogenic risk. Conclusion: Lipid ratios can be used as reliable tools for assessing cardiovascular risk of naïve HIV-infected patients who received HAART.

New insights of liquid biopsy in ovarian cancer

Published on: 29th September, 2022

Through the development of new analysis technologies, many issues regarding the approach to tumoral diseases have been elucidated. With analytical assays developed in the last years, various omics technologies have evolved in such a manner that the characteristics of tumor cells and products can be evaluated (assessed) in the bloodstream of cancer patients at different times. Ovarian Cancer (OC) is one of the most difficult to diagnose umors, with low survival rates due to the high heterogeneity of these diseases that are distinct in terms of etiology and molecular characteristics, but which simply share an anatomical appearance. Recent findings have indicated that several types of ovarian cancer classified into different histotypes are in fact derived from non-ovarian issues and share few molecular similarities. Within this context, ovarian cancer screening and diagnosis can be made through the evaluation of circulating tumor cells in peripheral blood using liquid biopsy technologies. Advances in the study of various molecules analyzed by liquid biopsy have shown that elucidation of intratumoural and intertumoural heterogeneity and spatial and temporal tumor evolution could be traced by serial blood tests rather than by histopathological analyses of tissue samples from a primary tumor. Therefore, evaluation of some molecules such as circulating tumor cells (CTC), circulating tumor DNA (ctDNA), circulating cell-free RNA (non-coding and mRNA, extracellular vesicles), tumor-educated platelets or different miRNAs using liquid biopsy could lead to improvement of patient management.

NAD⁺ Biology in Ageing and Chronic Disease: Mechanisms and Evidence across Skin, Fertility, Osteoarthritis, Hearing and Vision Loss, Gut Health, Cardiovascular–Hepatic Metabolism, Neurological Disorders, and Muscle

Published on: 26th January, 2026

Background: Nicotinamide adenine dinucleotide (NAD⁺) is a pivotal coenzyme and signaling substrate that integrates redox balance with mitochondrial energy production, DNA repair, epigenetic control, and cellular stress resilience. Declines in NAD⁺ availability—frequently observed with ageing, chronic inflammation, and metabolic stress—have intensified interest in NAD⁺ restoration as a potential strategy to influence disease biology across multiple organ systems.Objective: This narrative review summarizes contemporary mechanistic and translational evidence on NAD⁺ biosynthesis and turnover, highlighting the de novo kynurenine pathway and vitamin B3–dependent salvage routes (nicotinic acid, nicotinamide, nicotinamide riboside, and nicotinamide mononucleotide). We also examine how major NAD⁺ consumers and sensors, sirtuins, poly(ADP-ribose) polymerases (PARPs), and CD38 link NAD⁺ status to inflammation, oxidative stress, and tissue dysfunction in diverse clinical contexts.Methods: Peer-reviewed literature on NAD⁺ metabolism, NAD⁺-dependent signaling, and preclinical/clinical studies of NAD⁺ precursors was evaluated and organized into: (i) core biochemical functions in cellular energetics, (ii) NAD⁺ consumption in genome maintenance and immune signaling, and (iii) organ-focused evidence relevant to skin disorders, infertility and reproductive health, osteoarthritis, hearing loss, vision decline, gut barrier dysfunction, cardiovascular and renal metabolism, hepatic steatosis, neurological diseases, and skeletal muscle health.Results: NAD⁺ supports glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation, while acting as an essential substrate for PARP-driven DNA repair and sirtuin-mediated deacylation programs that shape mitochondrial fitness, inflammatory tone, and metabolic flexibility. Across experimental models, impaired NAD⁺ homeostasis repeatedly associates with mitochondrial dysfunction, heightened oxidative injury, and dysregulated immune–barrier responses, features shared by intestinal inflammation, neurodegeneration and ischemic injury, cardiometabolic disease, kidney injury, and fatty liver disease. Supplementation with NAD⁺ precursors (notably NR and NMN) reliably elevates NAD⁺ in preclinical systems and increases circulating NAD⁺ metabolites in humans, with early signals of pathway engagement; however, clinical outcomes remain heterogeneous across populations, dosing regimens, and endpoints. Evidence for intravenous NAD⁺ “drip” therapy is comparatively limited and insufficiently standardized, with constraints related to tolerability, dose consistency, and cost, underscoring the need for controlled trials.Conclusion: NAD⁺ occupies a central position at the interface of energy metabolism, genome integrity, and immunometabolic signaling, providing a coherent framework for understanding how cellular stress can propagate multisystem dysfunction. Although NAD⁺-boosting strategies are biologically plausible and mechanistically supported, definitive clinical benefit across skin, fertility, osteoarthritis, sensory decline, gut disorders, cardiovascular and hepatic disease, neurological conditions, and muscle health will require well-designed human studies with standardized biomarkers, safety surveillance, and clinically meaningful endpoints.

Germline BRCA1 Mutation inSquamous Cell Carcinoma of Oesophagus: Driver versus Passenger Mutation

Published on: 2nd July, 2024

We report a rare case of 62-year-old South Asian women who visited the Molecular Pathology and Genomics Department for hereditary germline cancer genetic testing after being diagnosed with oesophageal cancer, reported as invasive keratinizing squamous cell carcinoma metastasized to the lymph nodes. Her personal history revealed that she was diagnosed with triple-negative breast cancer five years before oesophageal cancer. Germline cancer testing showed pathogenic variants in BRCA1 gene c.68_69delAG, which proved it a hereditary breast and ovarian cancer syndrome. She was started on PARP inhibitors but developed some secondary respiratory failure and succumbed to death. Less than 10 cases have been reported in the literature of the association of germline BRCA1 and Squamous cell Carcinoma – the esophagus. The article focuses on the probable pathogenesis of BRCA1 mutation with non-classic malignancies and the response of Poly adenosine diphosphate ribose polymerase inhibitors (PARP) inhibitors in such a scenario. We report an unusual manifestation of the BRCA1 gene with second primary oesophageal squamous cell cancer occurring five years later to triple-negative breast cancer.
