[Guidelines for the diagnosis and treatment of hereditary angioedema].

Hereditary angioedema (HAE) is a rare but potentially fatal genetic disorder with nonpitting, nonerythematous, and not pruritic swelling which can affect the hands, feet, face, genitals and visceral mucosa. The type, frequency, and severity of the attacks vary between patients, and over the lifetime of an individual patient. Efforts in Croatian counties have identified approximately 100 patients (but there must be more undiagnosed patients).

Tibial stress fracture simulate osteomyelitic foci in the course of chronic recurrent multifocal osteomyelitis.

Chronic recurrent multifocal osteomyelitis (CRMO) is an extremely rare and most severe form of chronic nonbacterial osteomyelitis of unknown etiology. Here we present the first case of a six-year-old girl in which was observed that the stress fracture mimic osteomyelitic foci in the course of CRMO.

Childhood-onset systemic lupus erythematosus in Croatia: demographic, clinical and laboratory features, and factors influencing time to diagnosis.

Objectives: Childhood-onset systemic lupus erythematosus (cSLE) presents with diverse clinical features and often with non-classical symptoms that may delay diagnosis and increase risk of morbidity and mortality. This paper aims to analyse incidence, and clinical and laboratory features of cSLE in Croatia between 1991 and 2010, and to identify factors influencing time to diagnosis.

Results: Medical records at three university-based tertiary care centres were analysed retrospectively for 81 children with cSLE (68 girls).

Rising trends in the prevalence of asthma and allergic diseases among school children in the north-west coastal part of Croatia.

Objective: To estimate time trends in prevalence of symptoms and reported diagnosis related to asthma, allergic rhinitis/conjunctivitis and eczema among school children in the north-west coastal part of Croatia.

Methods: Results of two identical cross-sectional surveys conducted on the same area 8 years apart (school years 2001/02 versus 2009/10) in complete adherence to the protocol of the International Study of Asthma and Allergies in Childhood were compared. Surveyed population comprised two age groups: 6-7 years (n = 1634 versus n = 1052) and 13-14 years (n = 2194 versus 1181).

Role of magnetic resonance imaging and scintigraphy in the diagnosis and follow-up of osteomyelitis in cat-scratch disease.

Cat-scratch disease (CSD) is a self-limiting infectious disease characterised with lymphadenopathy in a patient with a history of cat contact. Cases of bone involvement in patients with CSD are rare. We reported a case of 11-year-old boy with prolonged intermittent fever, inguinal lymphadenopathy and osteomyelitis.

Prevalence of asthma and allergic diseases in Croatian children is increasing: survey study.

Aim: To estimate the prevalence of asthma, allergic rhinitis, and atopic dermatitis among school children in the region of Primorsko-goranska County in Croatia, and compare the results with data from other countries.

Methods: The study was conducted during the 2001-2002 school year, in complete adherence to the Phase One protocol of the International Study of Asthma and Allergies in Childhood (ISAAC). The target population comprised two age groups (6-7 and 13-14 years) in the region of Primorsko-Goranska County in Croatia.

Gastroesophageal reflux and sequelae of chronic tubotympanal disorders in children.

Objective: To compare sequelae of chronic tubotympanal disorders in children with and without gastroesophageal reflux (GER).

Material And Methods: In 32 patients with chronic tubotympanal disorders GER was studied by means of 24-h continuous esophageal pH monitoring. After a period of 2-6 years (mean 4 years) sequelae of the tubotympanal disorders were examined, together with the clinical status of the ears and hearing status.

[Congenital diaphragmatic hernia in older children].

The incidence of congenital diaphragmatic hernia (CDH) is about 4.8/10,000 live births. Its typical clinical presentation is respiratory distress occurring immediately after birth or in the first few hours or days of a child's life.

Manifold significance of serum eosinophil cationic protein in asthmatic children.

Asthma is the result of complex interaction between different cells, mediators and nervous system that leads to an inflammatory response accompanied by increased bronchial hyperactivity. Its clinical manifestations include recurrent cough, wheezing and difficult breathing. The purpose of this study was to establish the possibility of diagnosing inflammation in asthmatic patients based on the assessment of serum eosinophil cationic protein (ECP), and of following the efficacy of asthmatic treatment by the levels of inflammation mediators.

Drug-induced acute tubulointerstitial nephritis: a case with elevated urinary cadmium.

Acute tubulointerstitial nephritis (ATIN) has many different causes, but is most frequently caused by drugs. We report a 13-year-old vegetarian girl with drug-induced ATIN, confirmed by renal biopsy, and simultaneous occurrence of elevated urinary cadmium. Four weeks prior to admission she had been treated with antibiotics and acetaminophen for respiratory infection, and remaining febrile, was treated with different "home-made" herbal mixtures.

Prolonged esophageal pH monitoring in the evaluation of gastroesophageal reflux in children with chronic tubotympanal disorders.

Background: Children with ear, nose and throat disorders are believed to have a high incidence of pathologic gastroesophageal reflux (GER). This study was designed to establish the frequency and ratio of pathologic GER in the development of chronic tubotympanal disorders.

Methods: Twenty-seven children with chronic tubotympanal disorders (mean age, 2 to 13 years; average age, 6.
