Incidence of type 1 diabetes mellitus in 0 to 14-yr-old children in Croatia--2004 to 2012 study.

BACKGROUND: The incidence of type 1 diabetes mellitus (T1DM) among children and adolescents increased during the last 50 yr. The T1DM incidence in Croatia was 8.87/100.000/yr over 1995-2003, with an annual increase of 9%, which placed Croatia among countries with moderate risk for T1DM. AIM: To investigate incidence rates and trends of T1DM from 2004 to 2012 in 0 to 14-yr-old Croatian children, and to compare the results with previous studies in Croatia and other European countries. METHODS: T1DM crude incidence rates are estimated for the entire group and three subgroups: 0-4, 5-9, and 10-14 yr. Standardized incidence is calculated using the method of direct standardization according to World Health Organization (WHO) standard world population. The incidence rates by gender, age groups, seasonality, and calendar year, and their interactions were analyzed using Poisson regression model. RESULTS: A total of 1066 cases were ascertained over 2004-2012. The standardized incidence was 17.23/100.000/yr (95% CI: 16.19-18.26), with no significant differences in incidence rates or trends between boys and girls. Statistically significant annual increase of 5.87% (p < 0.001) was found for the whole group, and for the subgroups 5-9 yr (6.82%; p < 0.001) and 10-14 yr (7.47%; p < 0.001). In the youngest subgroup (0-4 yr), annual increase was lower (2.43%; p = 0338) and not statistically significant. CONCLUSION: The incidence of childhood T1DM is increasing in Croatia, thus placing Croatia among countries with high risk for T1DM. The annual increment of 5.87% is considerably lower than 9.0% reported earlier, but still higher than the European average (3.9%). The increase in incidence ceased in youngest children.

Regional differences in incidence and clinical presentation of type 1 diabetes in children aged under 15 years in Croatia.

AIM: To determine regional differences in the incidence, incidence trends, and clinical presentation of type 1 diabetes in children under the age of 15 years in Croatia in a 9-year period (1995-2003). METHODS: We included the patients who had been diagnosed with the disease and had started the insulin treatment before they were 15 years old. Regional differences between eastern, central, and southern Croatia were observed. The gross incidence was expressed by the number of newly diagnosed type 1 diabetes patients in 100000 children of the same age and sex per year, ie, for the 0-14 age group, and for the 0-4, 5-9, and 10-14 subgroups. RESULTS: The highest incidence was observed in southern Croatia (10.91 per 100000/y) and the lowest in central Croatia (8.64 per 100000/y), and in eastern Croatia the incidence was 8.93 per 100000/y. All three regions showed a growing incidence trend, which was significant only in eastern and southern Croatia. There was 35.9% of patients with diabetic ketoacidosis in eastern Croatia, 41.7% in central Croatia, and 31.28% in southern Croatia. CONCLUSION: Croatian regions show differences in the incidence, incidence trends, and disease presentation of type 1 diabetes. A further follow-up is needed to establish whether the regional differences are a consequence of the population dynamics in the observed period or they will continue to exist, pointing to differences in environmental risk factors.

Clinical characteristics at presentation of type 1 diabetes mellitus in children younger than 15 years in Croatia.

The aim of the study was to determine the clinical and biochemical characteristics of type 1 diabetes mellitus (DM) at presentation in children younger than 15 years in Croatia during a 9-year period, with special attention to diabetic ketoacidosis (DKA) incidence. The registered data set comprised blood glucose, pH, serum bicarbonate levels, and clinical symptoms at disease manifestation. During the study period, 692 children were diagnosed with type 1 DM. Polydipsia (96.7%), polyuria (96.05%), and weight loss (82.7%) were the most frequent symptoms anticipating disease detection. Enuresis was recorded in 11.55%. A total of 36.41% patients had DKA (pH < 7.3) at disease onset. During the 9-year period, the percentage of children presenting with DKA at time of diagnosis decreased from 41.67% to 33.33% (z = 1.68, p = 0.046). A positive family history of DM, the only factor with an impact on the DKA incidence rate in our population, lowers the probability of the development of ketoacidosis. This study confirms the importance of the detection of the classic symptoms of polyuria, polydipsia, and weight loss in patients with new-onset type 1 DM. The percentage of patients with DKA at diabetes onset decreased during the observed period but is still high and includes one-third of all patients. This is why in every acutely ill child, especially at a younger age, one should evaluate the possibility of type 1 DM to avoid the development of ketoacidosis.

[Low doses of sulphonyluria as a successful replacement for insulin therapy in a patient with neonatal diabetes due to a mutation of KCNJ11 gene encoding Kir6.2]. / Niske doze sulfonilureje kao uspjesna zamjena za inzulin u lijecenju neonatalnog dijabetesa uzrokovanog aktivirajucom mutacijom Kir6.2.

Neonatal diabetes mellitus is a rare metabolic disorder with an estimated incidence of 1:300.000 to 400.000 newborns, and less than 50% of the neonates have permanent neonatal diabetes mellitus (PNDM). Recently, activating mutation in the KCNJ11 gene encoding Kir6.2 subunit of the adenosin triphosphate-sensitive potassium (K(ATP)) channel has been described as the most frequent cause of PNDM. Under physiological circumstances K(ATP) channel closure plays a central role in glucose-stimulated insulin secretion from pancreatic beta cells. Sulphonylurea drugs stimulate insulin secretion by binding to and closing K(ATP) channels and thus bypassing beta cell metabolism stimulate the same chain of reactions as glucose. We describe a boy diagnosed with PNDM at the age of 3 months when insulin therapy was started, and at the age of 4.5 years KCNJ11 gene was sequenced and found that the boy carried a de novo activating R201H mutation. Insulin therapy was successfully switched to low doses of oral glibenclamide. Accordingly, it is important to emphasize that every person diagnosed with diabetes before six months of life, however old they actually are, should be tested for K(ATP) mutations which is offered via the website www.diabetesgenes.org.

[Marden-Walker syndrome--a case report]. / Marden-Walkerov sindrom--prikaz bolesnice.

Up to now 36 cases of Marden Walker syndrome (MIM # 248700) have been reported. The underlying pathological mechanism has not yet been clearly established, but it is assumed that it is a developmental disorder of the central nervous system which is inherited in an autosomal recessive manner. Three main diagnostic criteria are blepharophimosis, congenital joint contractures and mask-like face, but numerous other anomalies have been described in these patients. We present a girl with clinical characteristics of Marden Walker syndrome, which has not yet been reported in our literature. Together with three major and many other clinical signs which confirm the diagnosis, our girl also has a vesicoureteral reflux and umbilical hernia, which have not yet been described in these patients.

[The characteristics of depression in the elderly]. / Karakteristike depresije u starijih osoba.

UNLABELLED: Depression is a patologic condition found in all age groups, including the elderly. It is not a normal part of aging. Because of the various symptoms and signs and gradual course of depression, it is very often unrecognized. PATIENTS AND METHODS: Study group included 223 patients aged over 65, who visited their family doctor at Postira and Milna clinics, island of Brac, in period from December 1, 2003 till March 1, 2004. Study subjects filled out three questionnaires: personal data, geriatric depression scale, and a short questionnaire about pain, designed by the Croatian Society for Pain Control. RESULTS: According to the score on the geriatric depression scale, 15% of patients had symptoms of severe depression and 34% of mild depression. Both sexes were equally represented. In those with depression, anxiety, irritability and nervousness were markedly expressed as compared with those without depression. In patients with ICV, the symptoms of depression were considerably more pronounced than in healthy population. The experience of pain was much more intense in depressive subjects. Painkillers were much more effective in the group of nondepressed subjects. In the depressed group, insomnia, insecurity and disturbing thoughts about future disease were more intense. Interpersonal relationships were disturbed, and the quality of life impaired due to the pain. CONCLUSION: Primary care physician is mostly the doctor of first contact for the elderly. Therefore, it is very important that general practitioners know how to recognize depressive symptoms.

Do we need the "adolescent crisis" diagnosis?

The aim of the study was to examine patients in adolescent crisis at the beginning of treatment and after a period of 12 months in order to evaluate the relative diagnostic and therapeutic validity. The study included 153 Split University students in adolescent crisis; 90 of them were treated by counseling and 63 served as controls. For diagnosis, Hampstead index and Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) multiaxial evaluation were used, allowing a wider insight into personal functioning. The study sample was split in 7 significantly different diagnostic subgroups. The counseling-treated examinees had better personality functioning after 12 months, but did not differ significantly from the control group. Some of their single functions were more severely disturbed at the very beginning. Counseling is a valuable therapeutic and diagnostic tool for adolescent crisis. The assessment must evaluate the entire person, because looking at only one aspect, due to different development and its place, a wrong conclusion may be reached. The "adolescents crisis" entity is clinically relevant.
