    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

    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

    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, “Grigore Alexandrescu” 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’s diameter when bigger than 8 cm and a positive IDRF status, with p < 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 < 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

    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

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

    No full text
    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

    Abdominal tumor masses are a very rare disease in the fetus. The authors present the first reported case of neonatal multicystic adenomatoid hamartoma of the pancreas associated with well-differentiated fetal epithelial subtype hepatoblastoma and reveal clinical, histologic, and imagistic aspects. Case presentation: A 36-week-old female newborn in whom a 25-week ultrasound showed a relatively homogeneous pancreatic echogenic mass (34 × 30 × 55 mm) with compression of the inferior vena cava and retrograde dilation. Postnatal CT showed a giant pancreatic tumor mass (113 × 70 × 60 mm), with areas enhancing contrast and cystic/necrotic areas and a hypodense, hypocaptive nodule of 8 × 6 mm located at segment IV of the liver; thrombosis of the subhepatic segment of the inferior vena cava and both renal veins. Histopathological and immunohistochemical studies confirmed the diagnosis of multicystic pancreatic adenomatoid hamartoma and well-differentiated fetal epithelial subtype hepatoblastoma. Conclusions: Pancreatic hamartoma can be difficult to diagnose (especially prenatal), with or without nonspecific symptoms. The synchronous presence of hepatoblastoma complicated the therapeutic conduct and prognosis of this case, with the diagnosis being confirmed histopathologically and immunohistochemically after liver biopsy

    A RARE ASSOCIATION: ANKYLOSING SPONDYLITIS AND A GENETIC DISEASE

    Ankylosing spondylitis (AS) is a chronic systemic inflammatory disease that affects the axial skeleton and sometimes the peripheral joints, leading to the development of bone bridges and ankyloses with impaired joint mobility and quality of life. The HLA B27 antigen, which occurs in approximately 97% of patients, is an important risk factor and also a diagnostic element to consider. The typical onset of the disease is in the 3rd-4th decade of life; juvenile onset of AS under 16 years is associated with the predominant involvement of peripheral joints and multiple complications (coxitis, acute anterior uveitis) which influence the evolution of the disease under treatment being related with a negative prognosis. Noonan syndrome is a genetic disease with dominant autosomal transmission characterized by a small stature and other phenotypic features associated with congenital heart defects, especially pulmonary stenosis and atrial septal defect. Multiple genes within the RAS subfamily involved in various cellular signaling pathways such as signal transmission via mitogen-activated protein kinases are responsible for the occurrence of the disorder. Different hematological diseases such as myeloproliferative syndrome and neoplastic disease, particularly affecting the lung, may be correlated with Noonan syndrome. We present the case of a young patient with juvenile onset AS and Crohn’s disease who has Noonan syndrome with operated pulmonary stenosis and septal atrial defect, the association of these diseases bringing together cumulative complications that required multiple therapies and surgical interventions with strict monitoring

    Background. Pulmonary arterial hypertension (PAH) is an important cause of morbidity and mortality in patients with systemic sclerosis (SSc). This condition is diagnosed by cardiac Doppler ultrasonography, right-heart catheterization, or by serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP). The aim of this study was to assess the association between serum NT-proBNP and nailfold capillaroscopic patterns in SSc patients. We also analyzed the association between pulmonary function parameters, NT-proBNP, and nailfold capillary findings in patients diagnosed with SSc and PAH. Material and methods. We retrospectively analyzed SSc patients and healthy controls from our institution between July 2016 - December 2018. We assessed by chart review: pulmonary artery systolic pressure (PASP), forced vital capacity (FVC), forced expiratory volume in 1 sec/forced vital capacity ratio (FEV1/FVC ratio), the number of nailfold capillaries/mm and NT-proBNP. Statistical analyses were performed using the Student’s t-test, ANOVA test and the Pearson’s correlation. Results. Seventeen patients with SSc and 17 healthy controls matched for age and gender were included. Among SSc patients, 13 had diffuse cutaneous SSc (dcSSc) and 4 patients had limited cutaneous SSc (lcSSc). PAH was identified in 10 SSc patients. In SSc patients, significant correlations have been identified between PASP and NT-proBNP (r=0.9, p<0.0001), nailfold capillaries density and PASP (r=-0.95, p<0.0001), and nailfold capillaries density and NT-proBNP (r=-0.84, p<0.0001). Conclusion. We suggest that in patients with SSc, NT-proBNP is significantly correlated with PASP and nailfold capillaroscopic findings

    Comparative Study of Natural Antioxidants from Glycine max, Anethum graveolensand&nbsp;Pimpinella anisum Seed and Sprout Extracts Obtained by Ultrasound-Assisted Extraction

    The study aimed to evaluate the antioxidant potential of sprout and seed extracts from three species of plants, namely Glycine max (GMsp-sprouts, GMsd-seeds), Anethum graveolens (AGsp-sprouts, AGsd-seeds) and Pimpinella anisum (PAsp-sprouts, PAsd-seeds), which are widely accepted by consumers and have various applications in food flavoring, and also in natural medical treatments in the pharmaceutical industries. These plants are rich in valuable compounds that show a remarkable antioxidant power and are associated with many health benefits. Ethanol extracts were obtained by ultrasound-assisted extraction and they were comparatively evaluated for their in vitro antioxidant properties. The extracts were characterized by HPTLC, HPLC-DAD, total phenol content (TPC), total flavonoid content (TFC) analysis and antioxidant activities with different assays, such as total antioxidant capacity (TAC), 2,2&prime;-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical cation decolorization assay (ABTS), 1,1-diphenyl 1-2-picryl-hydrazyl (DPPH) and iron binding ability of chelators. Our results showed that the sprout and seed extracts of the studied plants exhibited a high content of phytochemicals and promising antioxidant properties. The highest polyphenols content was detected for AGsd (53.02 &plusmn; 0.57 mg/g DW), PAsd (48.75 &plusmn; 0.34 mg/g DW) and the highest flavonoids content for PAsp (26.84 &plusmn; 0.57 mg/g DW). Moreover, the presence of valuable compounds was demonstrated by using HPTLC, FT-IR and HPLC-DAD techniques. In order to have a better understanding of the relationship between the biological properties and the electronic structure, a molecular modelling study of genistein was also conducted. Our approach to the comparative assessment of these three plant species was based on a priori knowledge from literature data; however, this study demonstrated that these plant extracts of seeds and also sprouts are excellent sources of natural antioxidants. Significant additional differences that were found in the phytochemical composition could be exploited in future research for pharmaceutical purposes
