Background and Objectives: Characterization of patients with endocarditis regarding demographic, clinical, biological and imagistic data, blood culture results and possible correlation between different etiologic factors and host status characteristics. Material and methods: This is a retrospective observational descriptive study conducted on patients older than 18 years admitted in the past 10 years, in the Cardiology Clinic of the Clinical County Emergency Hospital Oradea Romania, with clinical suspicion of bacterial endocarditis. Demographic data, clinical, paraclinical investigations and outcome were registered and analyzed. Results: 92 patients with definite infective endocarditis (IE) according to modified Duke criteria were included. The mean age of patients was 63.80 ± 13.45 years. A percent of 32.6% had health care associated invasive procedure performed in the 6 months before diagnosis of endocarditis. Charlson’s comorbidity index number was 3.53 ± 2.029. Most common clinical symptoms and signs were: shortness of breath, cardiac murmur, fever. Sixty-six patients had native valve endocarditis, 26 patients had prosthetic valve endocarditis and one patient was with congenital heart disease. Blood cultures were positive in 61 patients. Among positive culture patient’s staphylococcus group was the most frequently involved: Staphylococcus aureus (19.6%) and coagulase negative Staphylococcus (18.5%). Most frequent complications were heart failure, acute renal failure and embolic events. Conclusions: Staphylococcus aureus IE was associated with the presence of large vegetations, prosthetic valve endocarditis and intracardiac abscess. Coagulase negative Staphylococcus (CoNS) infection was associated with prosthetic valve dysfunction. Streptococcus gallolyticus etiology correlated with ischemic embolic stroke and the presence of large vegetations. Cardiovascular surgery was recommended in 67.4% of patients but was performed only on half of them. In hospital death occurred in 33.7% of patients and independent predictors of mortality were congestive heart failure and septic shock.

Tuberous sclerosis complex (TSC) is a rare autosomal dominant neurocutaneous syndrome. It is manifested mainly in cutaneous lesions, epilepsy and the emergence of hamartomas in several tissues and organs. The disease sets in due to mutations in two tumor suppressor genes: TSC1 and TSC2. The authors present the case of a 33-year-old female patient registered with the Bihor County Regional Center of Medical Genetics (RCMG) since 2021 with a TSC diagnosis. She was diagnosed with epilepsy at eight months old. At 18 years old she was diagnosed with tuberous sclerosis and was referred to the neurology department. Since 2013 she has been registered with the department for diabetes and nutritional diseases with a type 2 diabetes mellitus (T2DM) diagnosis. The clinical examination revealed: growth delay, obesity, facial angiofibromas, sebaceous adenomas, depigmented macules, papillomatous tumorlets in the thorax (bilateral) and neck, periungual fibroma in both lower limbs, frequent convulsive seizures; on a biological level, high glycemia and glycated hemoglobin levels. Brain MRI displayed a distinctive TS aspect with five bilateral hamartomatous subependymal nodules associating cortical/subcortical tubers with the frontal, temporal and occipital distribution. Molecular diagnosis showed a pathogenic variant in the TSC1 gene, exon 13, c.1270A>T (p. Arg424*). Current treatment targets diabetes (Metformin, Gliclazide and the GLP-1 analog semaglutide) and epilepsy (Carbamazepine and Clonazepam). This case report presents a rare association between type 2 diabetes mellitus and Tuberous Sclerosis Complex. We suggest that the diabetes medication Metformin may have positive effects on both the progression of the tumor associated with TSC and the seizures specific to TSC and we assume that the association of TSC and T2DM in the presented cases is accidental, as there are no similar cases reported in the literature.

Cardiofaciocutaneous (CFC) syndrome [Online Mendelian Inheritance in Man (OMIM) #115150] is characterized by craniofacial dysmorphism, heart malformation, ectodermal abnormalities, neuromotor delay and intellectual disability. It is not a frequent disease, about 300 cases have been reported in the medical literature. We describe the case of a 34-year-old patient presenting with CFC syndrome phenotype, monitored since the age of 1 1/2 years. Clinical findings included craniofacial dysmorphism, development delay, heart malformation and severe intellectual disability. The evolution was with progressive intellectual disability, hypogonadism, hypertrophic cardiomyopathy, wrinkled palms and soles. Molecular analysis showed a heterozygous variant in the B-Raf proto-oncogene, serine/threonine kinase (BRAF) gene (7q34): NM_001354609.2:c.1502A>G, with pathogenic significance. We report this case, observed along a period of 33 years, for illustration of clinical evolutive particularities, and for difficulties in establishing the positive diagnosis.

Phenylketonuria (PKU) is caused by mutations in the phenylalanine hydroxylase (PAH) gene and is characterized by altered amino acid metabolism. More than 1500 known PAH variants intricately determine a spectrum of metabolic phenotypes. We aim to report on clinical presentation and PAH variants identified in 23 hyperphenylalaninemia (HPA)/PKU Romanian patients. Our cohort exhibited classic PKU (73.9%, 17/23), mild PKU (17.4%, 4/23), and mild HPA (8.7%, 2/23). Severe central nervous system sequelae are frequent in our cohort in late-diagnosis symptomatic patients, which highlights yet again the significance of an early dietary treatment, neonatal screening and diagnosis, and facilitated access to treatment. Next-generation sequencing (NGS) identified a total of 11 PAH pathogenic variants, all previously reported, mostly missense changes (7/11) in important catalytic domains. c.1222C>T p.Arg408Trp was the most frequent variant, with an allele frequency of 56.5%. Twelve distinct genotypes were identified, the most frequent of which was p.Arg408Trp/p.Arg408Trp (34.8%, 8/23). Compound heterozygous genotypes were common (13/23), three of which had not been previously reported to the best of our knowledge; two correlated with cPKU and one showed an mPKU phenotype. Generally, there are genotype–phenotype correlation overlaps with the public data reported in BIOPKUdb; as our study shows, clinical correlates are subject to variation, in part due to uncontrolled or unknown epigenetic or environmental regulatory factors. We highlight the importance of establishing the genotype on top of using blood phenylalanine levels.

Background/Objectives: Tuberous sclerosis complex (TSC) is a rare, autosomal dominant genetic disorder caused by mutations in the TSC1 and TSC2 genes, which disrupt the regulation of the mammalian target of rapamycin (mTOR) pathway, a critical regulator of cellular growth. The disorder presents as a multisystem condition, with benign tumors (hamartomas) developing in organs such as the brain, skin, heart, kidneys, and lungs, leading to significant clinical variability and impact on quality of life. This review aims to summarize recent advances in the understanding of TSC pathogenesis and clinical variability and evaluate the therapeutic breakthroughs in targeted treatments. Methods: A narrative review was conducted using various available databases. We applied objective evaluation metrics, such as the impact factor of the journals and the citation count, to assess the quality of the studies. Results: Targeted therapies, particularly mTOR inhibitors (mTORis), have shown efficacy in reducing hamartoma size, improving neuropsychiatric symptoms, and enhancing patient outcomes. Despite these advances, variability in disease expression poses challenges in diagnosis and individualized management strategies. Conclusions: Challenges such as early diagnosis, optimizing long-term outcomes, and addressing residual unmet needs remain critical. Future research should prioritize precision medicine approaches and patient-centered care models within centers of expertise to improve treatment efficacy and quality of life for individuals with TSC.
