Background: Langerhans cell histiocytosis (LCH) is a rare disease with an incidence of less than 10 per million, and characterized by the clonal proliferation of pathogenic Langerhans cells. The clinical courses are diverse, ranging from spontaneously remitting single organ disease to life-threatening multisystem involvement. One of the serious complications of LCH is diabetes insipidus (DI), and patients with CNS-risk lesions had higher cumulative incidence of DI. On the othe...

Background: WDR11 has recently been reported as one of the causative genes of hypogonadotropic hypogonadism (HH). To date, five missense mutations in WDR11 have been identified in six patients with normosmic isolated HH (nIHH) or Kallmann syndrome (KS).Methods: We performed mutation screening of WDR11 for 46 cases with various types of HH. RT-PCR was carried out for a patient with a mutation. The protein structure of the mutant...

Background: The intelligence prognosis of congenital hypothyroidism (CH) is remarkably improved by early detection and optimal levothyroxine (LT4) treatment. Some groups have reported that initial LT4 overtreatment results in a subsequent decrease of cognitive function. In universal guidelines, an initial dose of 10–15 μg/kg per day of LT4 is recommended. However, there are cases of LT4 overdosing.Obj...

Background: In initial treatment of DKA, volume expansion should begin with 0.9% saline to restore the peripheral circulation. The use of large amounts of chloride-rich/bicarbonate-free fluids may cause the rapid development of hyperchloremic metabolic acidosis, which is described in ISPAD Clinical Practice Consensus Guidelines 2018.The severity of DKA, defined by pH, HCO3- Base Excess (BE), is one of the factor...

Introduction: Thyroid nodules occur in 1.8% children which is not so often in comparison to adults (19–68%), but in children they appear to be at higher risk of malignancy (22–26% vs.5–10% respectively). It has been shown that the probability of thyroid nodules malignancy correlates with the presence of characteristic ultrasonographic features. Elastography - the noninvasive ultrasound imaging technique based on estimation of the tissue flexi...

Introduction: Elastography is a noninvasive imaging technique based on estimation of the tissue flexibility. There are two methods of elastography: Static Elastography and Shear Wave Elastography. Scale of deformation under pressure is presented as a colourful map – elastogram, where red colour signify soft tissues, green colour signify middle tough tissues and blue colour signify tough tissues. Analysis of elastograms enable us to present results as ROI1/ROI2 index. In a...

Background: Elastography is non-invasive ultrasound method of imaging based on estimation of mechanical properties (elasticity) of the tissue. Recent data has shown its ability to differentiate benign from malignant tumours. Decreased flexibility in comparison to around tissue is characteristic for malignant tissues, like most thyroid carcinoma (except follicular thyroid carcinoma). Analysis of the image gives the result presented as a ROI1/ROI2 index.Ob...
