[Hypertensive crisis in a 3-year-old boy - neurovascular conflict?] / Przelom nadcisnieniowy u 3-letniego chlopca ­ konflikt naczyniowo-nerwowy?

Hypertensive crisis is a sudden rise in blood pressure with accompanying clinical symptoms. The disease is extremely rare in small children and is always a complication of secondary hypertension. CASE REPORT: 3-year-old boy (spontaneous delivery, 37 week of gestation, birth weight 2170g, 10 AS, unremarkable family history) was admitted to a hospital because of weight loss (1.5 kg, i.e. approx. 15% in 6 months), anorexia, abdominal and limb pain and lethargy. On admission, very high blood pressure values (190/150 mm Hg), lean subcutaneous tissue, frequent blinking, height 88 cm (<3c), body weight 9.5 kg (<3c). In additional tests: blood morphology, parameters of renal function, ions, gasometry, catecholamine urinary excretion, steroid profile and daily cortisol profile were within normal limits. Elevated plasma renin activity was found. In imaging studies kidneys, adrenal glands and renal arteries were normal. Normotension was not obtained on two antihypertensive drugs - metoprolol and amlodipine. In angio-CT tortuous right vertebral artery, extending to the left on the anterolateral surface of the medulla oblongata - possible compression of the vessel of the left side of medulla - was found. Diagnosis of neurovascular conflict was made. The patient was consulted by neurosurgeon who declare no possibility of surgical treatment of anomalies. In the treatment, according to the literature, a drug blocking the renin-angiotensin-aldosterone-enalapril system was used, which normalized blood pressure. At the same time, intensive nutritional treatment was used. Resolution of symptoms and weight gain was observed. In further follow-up patients' parents withdrew enalapril lawlessly, which did not lead to recurrent rise in blood pressure. The latter may suggest other, transient cause of hypertensive crisis e.g. intoxication. CONCLUSIONS: Severe hypertension in pediatric patients can give symptoms as weight loss and behavioral disorders. In the diagnostic of hypertensive crisis in children, neuroimaging studies and toxicological tests should be performed.

Interstitial Lung Disease in Children With Selected Primary Immunodeficiency Disorders-A Multicenter Observational Study.

Primary immunodeficiencies (PIDs) are rare disorders of the immune system encompassing inborn errors of immunity. Primary antibody deficiencies constitute the largest group of PID with common variable immunodeficiency (CVID) being the most common symptomatic form. Combined immunodeficiencies (CID) accompanied by antibody deficiency can mimic CVID and these patients need the verification of the final diagnosis. Respiratory involvement, especially interstitial lung disease (ILD), poses a relevant cause of morbidity and mortality among patients with PID and in some cases is the first manifestation of immunodeficiency. In this study we present a retrospective analysis of a group of children with primary immunodeficiency and ILD - the clinical, radiological, histological characteristics, treatment strategies and outcomes. Eleven children with PID-related ILD were described. The majority of them presented CVID, in three patients CID was recognized. All patients underwent detailed pulmonary diagnostics. In eight of them histological analysis of lung biopsy was performed. We noted that in two out of 11 patients acute onset of ILD with respiratory failure was the first manifestation of the disease and preceded PID diagnosis. The most common histopathological diagnosis was GLILD. Among the analyzed patients three did not require any immunosuppressive therapy. All eight treated children received corticosteroids as initial treatment, but in some of them second-line therapy was introduced. The relevant side effects in some patients were observed. The study demonstrated that the response to corticosteroids is usually prompt. However, the resolution of pulmonary changes may be incomplete and second-line treatment may be necessary.

Progressive bronchiectasis and CMC in a patient with STAT1 GOF - a rare case of primary immunodeficiency.

Bronchiestasis is a common complication developing in patients with primary immunodeficiency disorders. AD GOF STAT1 defi-ciency is characterized by CMC, repeated infections, and autoimmunity. It is the most frequently diagnosed entity in a group of PIDs with CMC. Here, we present the first Polish case of a female patient with early-onset bronchiestasis accompanied by CMC and a severe course of infections who was genetically diagnosed with AD GOF1 STAT1 mutation at the age of 15.

Computed Tomography (CT) Angiography in Pre-Embolization Assessment of Location of Gastrointestinal Bleeding in Paediatric Patient with Granulomatosis with Polyangiitis (Wegener's Granulomatosis) - Case Report.

BACKGROUND: Acute gastrointestinal bleeding is an emergency with a high morbidity and mortality. Early diagnosis and appropriate intervention can be lifesaving and can prevent long-term complications. CASE REPORT: In this case report, we discuss and illustrate the role of CT angiography in the evaluation of acute, active gastrointestinal haemorrhage and show its usefulness prior to embolization. We describe a 15-year-old girl with granulomatosis with polyangiitis, formerly known as Wegener's granulomatosis. CONCLUSIONS: An accurate pre-embolization assessment of bleeding with CT angiography shortens the total diagnostic time, which results in prompt and more effective endovascular treatment.We describe the clinical presentation of our patient and present diagnostic and interventional radiologic findings.

Mixed partial anomalous pulmonary venous drainage coexistent with an aortic valve abnormality - analysis of ultrasound diagnostics in a 10-year-old girl with Turner syndrome.

The authors present a case of echocardiographic diagnosis of a rare congenital cardiovascular anomaly in the form of mixed partial anomalous pulmonary veins connection in a 10-year-old girl with Turner syndrome and congenital mild stenosis of insufficient bicuspid aortic valve, made while diagnosing the causes of intestinal tract bleeding. The article presents various diagnostic difficulties leading to the delayed determination of a correct diagnosis, resulting from the absence of symptoms of circulatory failure in the early stage of the disease and the occurrence of severe and dominant auscultatory phenomena typical for congenital aortic valve defect which effectively masked the syndromes of increased pulmonary flow. The authors discuss the role of the impact of phenotypic characteristics of the Turner syndrome, in particular a short webbed neck restricting the suprasternal echocardiographic access and the presence of psychological factors associated with a long-term illness. The importance of indirect echocardiographic symptoms suggesting partial anomalous pulmonary veins connection in the presence of bicuspid aortic valve, e.g. enlargement of the right atrium and right ventricle, and paradoxical interventricular septum motion were emphasized in patients lacking ASD, pulmonary hypertension or tricupid and pulmonary valve abnormalities. The methodology of echocardiographic examination enabling direct visualization of the abnormal vascular structures was presented. Special attention was paid to the significance of highly sensitive echocardiographic projections: high right and left parasternal views in sagittal and transverse planes with patient lying on the side, with the use of two-dimensional imaging and color Doppler. Finally, the limitations of echocardiography resulting from the visualization and tracking of abnormal vascular structures hidden behind ultrasound non-conductive tissues were indicated, as was the role of other diagnostic modalities, such as angio-CT and/or nuclear magnetic resonance.
