Unusual presentations of actinomycosis: a case series and literature review.

Introduction: To review unusual actinomycosis cases that appeared as a diagnostic and therapeutic challenge at our institution and to present a literature review on the usual clinical presentations.

Methodology: This retrospective review included all patients hospitalized for actinomycosis in a 10-year period at the University Hospital for Infectious Diseases "Dr. Fran Mihaljević", Zagreb, Croatia.

Clinical characteristics of hospitalized adults and adolescents with herpes zoster in Croatia: more than 20 years of a single-center experience.

Aim: To evaluate the clinical characteristics of adult and adolescent Croatian patients hospitalized for herpes zoster over a period of 21 years in the largest national center for infectious diseases (catchment area approximately 25% of the Croatian population).

Methods: This retrospective chart review included all patients older than 15 years hospitalized for herpes zoster at the University Hospital for Infectious Diseases "Dr. Fran Mihaljević" between January 1, 1996 and December 31, 2016.

Combined Albenazole-Praziquantel Treatment in Recurrent Brain Echinococcosis: Case Report.

We present a 40-year-old woman with a history of relapsing echinococcosis who had undergone a number of surgical procedures for cyst removal (right pulmectomy, cardiac surgery and 6 subsequent brain surgeries and two gamma knife procedures) and was admitted to University Hospital for Infectious Diseases "Fran Mihaljeviæ", Zagreb, Croatia in 2014 for pre-operative medical treatment of brain hydatidosis in the right parietal region. We aimed to attain a high cyst albendazole sulphoxide (ASO) concentration in order to achieve a more pronounced protoscolex inactivation and a high serum ASO concentration (reflecting the tissue concentrations) to reduce the risk of disease recurrence. The patient was treated with a higher dose of albendazole (15 mg/kg/day for 4 wk) that we had found effective in patients with liver hydatidosis, and combined with praziquantel over the last 14 d at a dose that is typically used to treat neurocysticercosis with an intention to improve ASO bioavailability.

A case report of severe recurrent varicella in an ankylosing spondylitis patient treated with adalimumab - a new side effect after 15 years of usage.

Background: Tumor necrosis factor-α (TNF-α) antagonists, most of which are monoclonal antibodies, became a widespread treatment for autoimmune diseases such as rheumatoid arthritis, ankylosing spondylitis, inflammatory bowel diseases, psoriasis, psoriatic arthritis, hidradenitis suppurativa and uveitis. Their use is based on the blockage of TNF-α, which plays an important role in granulomas formation, development of phagosomes, activation and differentiation of macrophages, immune response against viral pathogens. The multiple adverse effects of TNF-α inhibition have been identified, including a two-to four-fold increased risk of active tuberculosis and other granulomatous conditions and an increased occurrence of some other serious bacterial, fungal and certain viral infections.

Albendazolesulphoxide concentrations in plasma and hydatid cyst and prediction of parasitological and clinical outcomes in patients with liver hydatidosis caused by Echinococcus granulosus.

Aim: To investigate the relationship between plasma and cyst concentrations of albendazolesulphoxide (ASO) and their effects on parasitological findings and disease recurrence in patients with liver hydatidosis.

Methods: The study was conducted at the University Hospital for Infectious Diseases Dr. Fran Mihaljević, Zagreb, Croatia, between August 2006 and January 2011.

[Relapsing polychondritis--case report].

Relapsing polychondritis (RP) is a rare systemic inflammatory disease in which recurrent episodes of cartilage inflammation result in destruction of ears, nose and tracheobronchal tract. The joints, eyes, audiovestibular system and cardiovascular system can also be involved. About 30% of patients with RP have coexisting autoimmune disease, or malignant disease like colon, breast, and lung carcinoma, or malignant lymphoma.

Parental administration of antipyretics to children with upper respiratory tract infections without consultation with a physician.

Aim: To evaluate the administration of antipyretics to children with upper respiratory tract infections (URTI) by their parents or guardians without consultation with physicians, and compare epidemiological and clinical characteristics of patients who received antipyretics and of untreated patients.

Methods: A prospective observational study was performed in three pediatric clinics in Zagreb, Croatia, from March to June 2002. A total of 171 children aged from 2 to 14 years with symptoms and signs of URTI lasting more than 2 days and fever above 38 °C lasting more than 2 days were included in the study.

Single oral dose of azithromycin versus 5 days of oral erythromycin or no antibiotic in treatment of campylobacter enterocolitis in children: a prospective randomized assessor-blind study.

Objective: To evaluate efficacy of a single oral azithromycin dose versus standard oral erythromycin regimen or no antibiotic for Campylobacter enterocolitis in children younger than or equal to 12 years of age.

Patients And Methods: Randomized parallel group assessor-blind trial testing for inequality in efficacy between treatments was done. Patients (N = 120) were enrolled at less than or equal to 48 hours since disease onset to receive erythromycin 50 mg kg day for 5 days, single-dose azithromycin 20 mg/kg or 30 mg/kg, or no antibiotic (no treatment control) (1: 1: 1: 1).

[ISKRA guidelines on sore throat: diagnostic and therapeutic approach--Croatian national guidelines].

Sore throat is most commonly caused by viruses, but when caused by bacteria, the most important is group A streptococcus (GAS). The aim of these guidelines is to determine optimal treatment for streptococcal sore throat and reasonable indications for tonsillectomy, as well as recommend how to differentiate streptococcal infection for which antibiotics are justified, from numerous other sore throats where antibiotics wont have a significant effect on disease course, but might contribute to bacterial resistance to antibiotics. The development of the guidelines was initiated by the Interdisciplinary Section for Antibiotic Resistance Control (ISKRA) of the Croatian Ministry of Health and Social Welfare in accordance with the principles of AGREE (Appraisal of Guidelines for Research and Evaluation) methodology which means that the guidelines are the result of consensus between all interested professional societies and institutions.

An unusual outcome in a child with hepatosplenic cat-scratch disease.

Typical cat-scratch disease (Bartonella henselae infection) in an immunocompetent child is usually associated with a history of scratch, bite or intimate contact with a cat. Most patients develop a non-tender papule in the scratch line after three to ten days. This may persist for only a few days or as long as two to three weeks.
