Duodenal carcinoid tumour – a case report

Duodenal carcinoids are rare tumours of the small intestine with heterogenous clinical and pathological characteristics. The long-term prognosis is very good if discovered in the early stages. We present the case of a patient with a non-functional duodenal carcinoid tumour discovered incidentally during an upper gastrointestinal endoscopy. The diagnosis was confirmed through immunohistochemistry. Treatment consisted of the endoscopic resection of the tumour and the surveillance of the patient for the following 2 years, with no signs of recurrence. We have conducted a literature review regarding the clinical manifestations, diagnosis, treatment, and follow-up of patients with this type of tumours

Nanoparticles in the treatment of chronic lung diseases

Nanoparticles, although considered a topic of modern medicine, actually have an interesting history. Currently, advances in nanomedicine hold great promise as drug carrier systems for sustained release and targeted delivery of diverse therapeutic agents. Nanoparticles can be defined as complex drug carrier systems which incorporate and protect a certain drug or particle. Nanoparticles can be administered via different routes, such as intravenous injection, oral administration, or pulmonary inhalation. Even though the use of nano-carriers via pulmonary inhalation is heavily debated, this system represents an attractive alternative to the intravenous or oral routes, due to the unique anatomical and physiological features of the lungs and the minimal interactions between the targeted site and other organs. Some of the widely used nano-carriers for the treatment of chronic pulmonary diseases, via pulmonary route, are as follows: polymeric nanoparticles, liposomal nano-carriers, solid lipid nanoparticles, and submicron emulsions. Nano-carrier systems provide the advantage of sustained-drug release in the lung tissue resulting in reduced dosing frequency and improved patient compliance. Further studies focusing on understanding the mechanisms of action of nanoparticles and improving their chemical structure are required in order to better understand the potential long-term risk of excipient toxicity and nanoscale carriers

Imatinib-induced interstitial pneumonitis – a literature review and case report

Imatinib is generally well tolerated, with mild common side effects such as nausea and vomiting, diarrhea, muscle cramps, fatigue, skin rash and edema; however, pulmonary complications are uncommon. A 73-year-old woman undergoing one month treatment with Imatinib for chronic myeloid neoplasm associated with eosinophilia was admitted for sudden alteration of her performance status, dyspnea at rest and productive cough. On clinical examination, the patient was hypoxic (oxygen saturation on room air was 87%), and auscultation of her lungs revealed diffuse bilateral fine crackles. Computed tomography showed bilateral pulmonary interstitial syndrome. Imatinib was discontinued and the patient received systemic corticosteroid therapy and oxygen therapy. After one month, the symptoms and radiological findings were resolved. When Imatinib therapy was resumed, respiratory symptoms reappeared, which is why treatment with Imatinib was interrupted. Imatinib-induced pneumonitis should take into consideration when patients develop respiratory symptoms or abnormal pulmonary radiological features

The molecular mechanisms linking metabolic syndrome to endometrial and breast cancers

The metabolic syndrome represents a plethora of cardio-metabolic risk factors including obesity, arterial hypertension, atherogenic dyslipidemia, hyperglycemia, accompanied by pro-inflammatory and pro-thrombotic state. The metabolic syndrome is one of the key risk factors for certain types of cancer. Among these malignancies, breast cancer and endometrial neoplasms require special attention. Incriminated major causes for the development of breast and endometrial cancer in metabolic syndrome patients are: the pro-inflammatory status and related cytokines, adipokine imbalances, hyperestrogenism, growth factors, disturbances in cancer microenvironment, insulin resistance and hyperinsulinemia. The metabolic syndrome consists of molecular dysregulations that create a pro-oncogenic status. Our review aims at providing a better understanding of the mechanisms underlying the link between the metabolic syndrome and endometrial and breast cancer

Renal damage induced by non-steroidal anti-inflammatory drug treatment

Non-steroidal anti-inflammatory drugs (NSAIDs) are extensively used worldwide due to their analgesic, antipyretic and antiinflammatory effects. NSAIDs (both non-selective NSAIDs and selective cyclooxygenase-2 inhibitors) have nephrotoxic potential, particularly when used chronically.The principal mechanism of action of NSAIDs is cyclooxygenase inhibition, which prevents the conversion of arachidonic acid to prostaglandins, prostacyclins and thromboxanes. In the kidney, prostaglandins induce vasodilation and counter the action of the renin-angiotensin-aldosterone system and the sympathetic nervous system, ensuring optimal renal perfusion. Inhibition of this mechanism by NSAIDs can result in renal damage: acute kidney injury through hemodynamic mechanism, acute interstitial nephritis, glomerular disease, papillary necrosis, water and electrolyte imbalances, HTN. Chronic NSAID use may lead to chronic kidney disease.The nephrotoxic effect is reduced in young patients without renal disease or other comorbidities, but increases significantly in elderly patients with pre-existing kidney disease, nephrotic syndrome, diabetes mellitus, severe congestive heart failure, volume depletion, cirrhosis with ascites, HTN, atherosclerosis, or in patients under treatment with diuretics, angiotensin-converting enzyme inhibitors, angiotensin receptor inhibitors

Age-related trends in colorectal cancer diagnosis: focus on evaluation of prehabilitation and rehabilitation programs

The increase in the prevalence of both colon and rectal cancer in recent years poses challenges for the medical system in terms of patient management and indirectly incurs significant finan-cial burdens. Purpose: The aim of this paper is to track the changes in the prevalance of the co-lon and rectal cancer at a tertiary clinic in Romania over time and to identify complementary methods to improve the prognosis and quality of life of cancer patients. Material and methods: We conducted an observational, longitudinal, population-based study, including all patients newly diagnosed with colon or rectal neoplasia within the time frame from 1 January 2013 to 1 January 2024 in a tertiary medical clinic in Romania. For each case included in the study, we gathered demographic data (age at the time of cancer diagnosis, gender, place of origin), loca-tion of the tumor, duration until surgical intervention, alternative treatment methods em-ployed (such as radiation or chemotherapy, and immunotherapy), and the length of survival. We also assess the feasiblity of physical prehabilitation and rehabilitation programs for inpa-tients diagnosed with malignant neoplasms of the colon or rectum. Results: The study found significant differences in patient ages and the execution of prehabilitation and rehabilitation practices between those admitted for colon and rectal cancer during the periods 2013-2018 and 2019-2023, with a notable shift in the prevalence of colon versus rectal cancer over these peri-ods. Conclusions: Prehabilitation and rehabilitation practices for colorectal cancer patients are underdocumented or suboptimal, with recent improvements in documentation, especially for rectal cancer due to colostomy needs, and an observed increase in patient age due to COVID-19 pandemic protocols. Additional research and the development of standardized protocols are needed

Arterial stiffness in aortic stenosis - complex clinical and prognostic implications

Arterial stiffness and degenerative aortic stenosis (AoS) are frequently associated leading to a combined valvular and vascular load imposed on the left ventricle (LV). Vascular load consists of a pulsatile load represented by arterial stiffness and a steady load corresponding to vascular resistance. Increased vascular load in AoS has been associated with LV dysfunction and poor prognosis in pre-intervention state, as well as after aortic valve replacement (AVR), suggesting that the evaluation of arterial load in AoS may have clinical benefits. Nevertheless, studies that investigated arterial stiffness in AoS either before or after AVR used various methods of measurement and their results are conflicting. The aim of the present review was to summarize the main pathophysiological mechanisms which may explain the complex valvulo-arterial interplay in AoS and their consequences on LV structure and function on the patients' outcome. Future larger studies are needed to clarify the complex hemodynamic modifications produced by increased vascular load in AoS and its changes after AVR. Prospective evaluation is needed to confirm the prognostic value of arterial stiffness in patients with AoS. Simple, non-invasive, reliable methods which must be validated in AoS still remain to be established before implementing arterial stiffness measurement in patients with AoS in clinical practice

Adipokines and Arterial Stiffness in Obesity

Adipokines are active molecules with pleiotropic effects produced by adipose tissue and involved in obesity-related metabolic and cardiovascular diseases. Arterial stiffness, which is a consequence of arteriosclerosis, has been shown to be an independent predictor of cardiovascular morbidity and mortality. The pathogenesis of arterial stiffness is complex but incompletely understood. Adipokines dysregulation may induce, by various mechanisms, vascular inflammation, endothelial dysfunction, and vascular remodeling, leading to increased arterial stiffness. This article summarizes literature data regarding adipokine-related pathogenetic mechanisms involved in the development of arterial stiffness, particularly in obesity, as well as the results of clinical and epidemiological studies which investigated the relationship between adipokines and arterial stiffness

Diagnostic difficulties in chronic kidney disease – Is it or is it not Fabry disease?

Introduction. Renal impairment and neurological symptoms are common manifestations of Fabry disease. Although rare, Fabry disease should be taken into consideration when consulting a patient who presents with neurological and renal impairment, acroparesthesia and fatigue. The aim of this paper is to discuss the case of a female patient presenting with mild systemic symptoms and consequent renal impairment. Case report. The female patient, aged 64, presented for a painful ankle swelling, acroparesthesias, nycturia and fatigue. We diagnosed a gout attack, but found that she had biological signs of renal impairment, aggravated by the use of non-steroidian anti-inflammatory drugs. The search for an etiology of her renal failure proved difficult because she refused the kidney biopsy. The positivity of pANCA antibodies added another potential cause of kidney disease. The mild deficiency of alpha-galactosidase could not fully support the diagnosis of Fabry disease. Discussions and conclusions. In women, Fabry disease should be suspected even if the symptomatology is not typical and as severe as in men. It is difficult to diagnose the Fabry disease in a female patient with chronic kidney disease, because of its polymorphic manifestations and association with other comorbidities, in our case, pANCA vasculitis
