AGROCHEMICAL CHARACTERIZATION OF SOILS FROM OLT COUNTY

In order to characterize from the agrochemical point of view the soils from Olt County, there were considered agrochemical studies conducted in the county by OSPA Olt in the period 2008-2012, on the entire surface of the county at all land use categories. In the period subject to the agrochemical study, soil samples were collected from agrochemicals plots with different surfaces according to usage and were analyzed: the pH, humus content, nitrogen, phosphorus and potassium. After analysis it was found that:- Soil humus content is low and very low to cca.48% of agricultural land, requiring large expenses with additional fertilization;-The presence of large areas of acidic soils (about 45% of agricultural land) limits yields per unit of area;- Low and very low-supply in mobile phosphorus (cca.57% of agricultural land) limiting production in all cultures and affects crop quality

Antioxidant teas from M. charantia and C. metuliferus plants waste

Abstract.Cucumis metuliferus and Momordica charantia represent two species with therapeutically properties of the Curcubitaceea family. This plants were adapted for cultivation in Romania, in Buzău county, and have been the subject of the present research. M. charantia and C. metuliferus have been widely used for various traditional Asian medicinal purposes and commonly consumed as vegetables. Moreover, various antioxidant, antiviral, antidiabetic and immunomodulatory properties have been demonstrated in various studies[1,2]. More and more farmers are interested in growing and marketing these fruits on the local market not only in the countries of origin but also in other countries. These species are productive and very little sensitive to diseases and climatic conditions. Next, we paid special attention to the fact that the leaves of the plants after the fruit harvest are usually discarded. In the future, by conducting in-depth studies, these leaves from agricultural waste will be able to become useful products for human nutrition and health from a new perspective in the form of tea. In this study we aim to highlight the chemical composition and antioxidant properties of M. charantia and C. metuliferus tea leaves, therefore obtaining a phytotherapeutic product from waste material. Material and methods: A preliminary phytochemical study was performed on tea leaves of Cucumis metuliferus and Momordica charantia. We performed the identification and quantification of different classes of compounds, by UV-Vis or HPTLC methods, as well as the determination of antioxidant activities, by DPPH and TAC methods. Results: The teas were prepared by infusing the leaves with water at 100ºC. C. metuliferus infused tea leaves contains a high amount of flavonoids, while M. charantia infused tea leaves contains a higher amount of polyphenols. Both teas presented impressive antioxidant activities. Conclusions This study demonstrated the variety of the chemical composition in flavonoids and polyphenols in the teas obtained from both species as well as a good antioxidant capacity. By the HPTLC method, chlorogenic acid was detected in considerable amounts in both varieties of tea. In conclusion, vegetable waste can be used in the future and used in products such as commercial teas, both for widespread use and for therapeutic purposes

An unusual clue in the diagnosis of primary Sjogren’s syndrome

Sjogren’s syndrome (SSj) is a chronic autoimmune disease mainly targeting the exocrine glands, but sometimes associating extra-glandular manifestations. Xerosis, purpura, Raynaud’s phenomenon, cutaneous vasculitis, annular erythema are the main forms of skin involvement. A 26-year-old female patient was admitted for diffuse erythematous rash and angioedema, xerophthalmia and symmetrical arthralgia of hand joints. Anti-nuclear antibodies, anti-SSA and anti-Ro52 antibodies were identified, Schirmer’s test was positive, thus the diagnoses of primary SSj and associated urticarial vasculitis were established. Treatment with oral methylprednisolone, azathioprine and hydroxychloroquine was initiated, with favourable response over the next week. Patients with primary SSj that develop cutaneous vasculitis, lymphadenopathies or lymphopenia may be at risk for additional extra-glandular manifestations, including non-Hodgkin lymphoma

Our Experience with Cyst Excision and Hepaticoenterostomy for Choledocal Cyst: A Single Center Case Review of 16 Patients

Background and Objectives: Choledocal cyst is a rare congenital disease of the biliary tree defined by dilatation of the extrahepatic and/or intrahepatic biliary ducts. Untreated, it leads to complications such as cholangitis, stone formation and malignant degeneration. The standard treatment for choledocal cyst is complete excision and subsequent biliary reconstruction via hepaticojejunostomy or hepatiocoduodenostomy. Materials and Methods: We report our experience with 16 pediatric cases of choledocal cyst over a 10-year period. Results: The predominant symptoms were nausea and jaundice, both at 62.5% (n = 10), followed by abdominal pain at 56.3% (n = 9). Ultrasonography was the diagnostic method used in all patients. Computed tomography was used in 75% (n = 12) and magnetic resonance imaging in 25% (n = 4) of cases. Age at the time of intervention ranged from 2 months to 17 years with a mean of 4 years and 5 months. The open approach was used in nine patients and the laparoscopic approach was used in seven patients, with one conversion to open surgery. Complete excision of the choledocal cyst was performed in 15 cases (93.7%), and partial excision with mucosectomy was performed in one case (6.2%). Eight patients (50%) underwent hepaticoduodenostomy and eight (50%) underwent hepaticojejunostomy, out of which one was attempted laparoscopically but was converted. We had a postoperative complication rate of 12.5% (n = 2) represented by anastomotic leak and pancreatitis. Conclusions: From our experience with these cases, we concluded that a wide hepaticoduodenostomy constitutes a favorable choice over the traditional hepaticojejunostomy, being more physiological and less time consuming.</jats:p

Association of Image-Defined Risk Factors with Clinical, Biological Features and Outcome in Neuroblastoma

Background: Neuroblastoma (NB) is the most common pediatric extracranial solid tumor and the most common cancer encountered in children younger than 12 months of age. Localized tumors have a good prognosis, but some cases undergo treatment failure and recurrence. The aim of the study was to analyze the link between the neuroblastoma risk factors and the prognosis for patients diagnosed with NB. Method: All patients admitted to the department of Pediatric Surgery, &ldquo;Grigore Alexandrescu&rdquo; Clinical Emergency Hospital for Children, between 1 January 2010 and 1 July 2022 were included in this analysis when diagnosed with neuroblastoma. Results: Thirty-one patients with NB were admitted to the surgical department, 20 boys and 11 girls. We observed an association between large tumors and positive imaging-defined risk factor (IDRF) status; The Fisher test showed an association between the tumor&rsquo;s diameter when bigger than 8 cm and a positive IDRF status, with p &lt; 0.001. We supposed that positive IDRF status at diagnosis may be linked to other prognostic factors. We discovered that an NSE value over 300 was associated with IDRF status (p &lt; 0.001, phi = 0.692) and death. Conclusions: This study confirms the impact of IDRF status at diagnosis as it can be clearly correlated with other risk factors, such as a high level of NSE, MYCN amplification status, large tumor size, incomplete tumor resection, and an unfavorable outcome

Cholecystectomy in Children: Indications and Timing

Background: Pediatric cholelithiasis has become increasingly diagnosed, partly due to enhanced imaging accessibility and rising obesity rates. Despite laparoscopic cholecystectomy being the standard treatment, the optimal timing for surgery remains debated, especially in complicated cases. The aim of our study is to analyze the demographic, clinical, and surgical characteristics of pediatric patients undergoing cholecystectomy and to identify the most favorable timing for surgery in terms of outcomes and complications. Material and methods: A retrospective study was conducted on 101 pediatric patients who underwent cholecystectomy between 2015 and 2024 at a tertiary children’s hospital. Patients were categorized based on surgical timing: elective, early (day 1–4), intermediate (day 5–14), and delayed (after day 14). Demographic data, clinical presentation, laboratory values, imaging, operative time, intraoperative findings, and postoperative complications were analyzed. Results: The median age was 15 years, with 64.35% female. Obesity was highly prevalent and significantly associated with choledocholithiasis and pancreatitis. Elective and delayed surgeries (after 14 days) had the shortest operative times (median: 2 h) and the lowest complication rates. Early surgeries (within 4 days) showed longer operative times and a higher incidence of intraoperative difficulties and complications. Histopathological findings did not influence clinical management, suggesting potential for selective examination. Conclusions: Elective or delayed cholecystectomy after a “cool-down” period of 5–14 days provides the most favorable outcomes in pediatric patients with complicated cholelithiasis. Conservative management remains appropriate for asymptomatic cases. A standardized approach to surgical timing may reduce complications and hospital cost

Hypertriglyceridemia Induced Acute Pancreatitis Caused by a Novel LIPC Gene Variant in a Pediatric Patient

Hypertriglyceridemia induced acute pancreatitis is a rare cause of pancreatitis in children. Hepatic lipase deficiency is an extremely rare cause of hypertriglyceridemia, reported in only a few families to date. Hepatic lipase is the enzyme involved in the hydrolysis of triglycerides and phospholipids in remnants of triglyceride-rich lipoproteins that have a role in the conversion of very low density lipoprotein remnants to low density lipoproteins. Hepatic lipase deficiency is inherited in an autosomal recessive pattern. Detection of heterozygous carriers of hepatic lipase mutations remains accidental at the population level, as affected persons with a heterozygous state of hepatic lipase mutation do not display specific lipoprotein abnormalities and also patients with complete hepatic lipase deficiency have inconstant phenotype. The proximal promoter of the LIPC gene consists of four polymorphic sites in complete linkage disequilibrium. Five missense mutations in encoding exons have been described and proved to be responsible for hepatic lipase deficiency to date: S267F, T383M, L334F, A174T, and R186H, affecting the activity and secretion of hepatic lipase. We identified a primary disorder of the lipid metabolism as the cause of the acute episode of pancreatitis in a four years old patient, consisting of hepatic lipase deficiency caused by a novel genetic variant of the LIPC gene, a gross deletion of the genomic region encompassing exon 1. This variant was not previously described in the literature in persons with LIPC-related disorders and its significance is currently uncertain, but in the presented clinical and paraclinical context, it has the characteristics of a pathological variant inducing a hepatic lipase deficiency phenotype.</jats:p

NLRP3 Inflammasome in Cardiovascular Disease: David's Stone against Goliath?

Abstract Inflammation is involved in initiation, development and complications of the vast majority of non-communicable diseases. Recent research demonstrated that inflammation is involved in pathogenesis of all major cardiovascular diseases. Different endogenous factors (LDL, nucleic acid strands, uric acid – collectively called „Damage Associated Molecular Patterns – DAMPs”) activate dedicated receptors („Pattern Recognition Receptors – PRR”) on monocytes, macrophages or dendritic cells responsible for the innate immunologic response. They have a major role in natural defense mechanisms against different pathogens and in normal conditions have a protective role. Among PRRs „NOD-like, leucin rich, pyrin containing (NLRP)” receptors are a 14-member family located in the cytoplasm. One of these is the NLRP3 resulting from nuclear transcription under the influence of NF-kB, a second messenger from membrane PRRs to the nucleus. Mostly the same factors responsible for NLRP3 intracellular expression stimulate its oligomerization resulting in a large protein complex, the NLRP3 inflammasome. This activates caspase-1 responsible for IL-1b and IL-18 production and initiates an inflammatory reaction leading to various pathologic processes, such as atherosclerosis, hypertension, diabetes and heart failure. This is the current story as we know it of the NLRP3 inflammasome, a small intracellular component that when inappropriately activated may does more harm than good.</jats:p
