Serum eosinophil cationic protein in children with atopic dermatitis.

BACKGROUND: Eosinophil cationic protein (ECP) is a cytotoxic agent secreted by activated eosinophils during allergic and inflammatory processes. The aim of the study was to determine the ECP level, absolute and relative eosinophil count and IgE antibodies in children with atopic dermatitis (AD) compared with those of nonatopic children, and to assess the correlation of these laboratory parameters with the clinical severity of AD. METHODS: This prospective study comprised 70 children. There were 49 children with AD aged 3-36 months, and the control group comprised 21 children with a negative personal and family history for atopic diseases. Detailed history, serum ECP levels (UniCAP FEIA), relative and absolute eosinophil counts and total serum IgE antibodies were determined in both groups. In the children with AD, skin involvement was measured by the SCORAD index. RESULTS: The calculated SCORAD index was between 16 and 83. IgE antibodies, relative and absolute eosinophil counts showed a significantly wider range of values and a statistically higher median (P < 0.001) in the patients with AD compared with the control group. These laboratory parameters did not correlate with the severity of AD. The serum ECP median level, in the children with AD, was 16.2 microg/L (range 3.01-65.30) compared with 5.92 microg/L (range 2.76-21.90) in the control group. Correlation of the total SCORAD index and the serum ECP levels was negative, weak (r = -0.065) and statistically not significant (P > 0.05). The same was found for the correlation of serum ECP and intensity of skin changes (r = -0.095) and serum ECP and subjective symptoms (r = -0.045). The correlation was positive, but weak and statistically not significant for the serum ECP and extent of the skin lesions (r = 0.079, P > 0.05). CONCLUSION: Elevated levels of ECP, relative and absolute eosinophil counts, as well as IgE antibodies were determined in the patients with AD. As these laboratory findings did not correlate with the severity of AD, they can be considered only as additional methods in the evaluation of patients with AD.

Coexistence of pemphigus herpetiformis and systemic lupus erythematosus.

A female patient with coexistence of pemphigus herpetiformis and systemic lupus erythematosus is described. She presented to our Department with pruritic vesicles on her trunk and extremities, which were later accompanied with butterfly like erythema on her face and with central nervous system (CNS) manifestations. The diagnosis of pemphigus herpetiformis was based on the clinical picture and immunofluorescence finding, because the histopathologic finding is not always typical for the diagnosis. The diagnosis of systemic lupus erythematosus was based on positive ANA and anti-dsDNA, presence of butterfly-like erythema on her face, and CNS manifestations. The patient was treated by corticosteroids in combination with immunosuppressants, which should ensure good control of both diseases. The coexistence of pemphigus herpetiformis and systemic lupus erythematosus has not been reported in recent literature.

Tinea incognito caused by trichophyton mentagrophytes -- a case report.

A case of widespread tinea due to Trichophyton mentagrophytes is described. A healthy 75-year-old woman presented with 134 typical tinea corporis and faciei lesions previously treated with topical steroids. The diagnosis was based on direct mycologic examination and culture. The treatment with oral administration of terbinafine for four weeks and topical application of clotrimazole resulted in complete clinical resolution of the lesions

Detection and genotyping of Borrelia burgdorferi sensu lato by polymerase chain reaction.

AIM: To isolate and genotype Borrelia burgdorferi genospecies in serum samples of Croatian patients with erythema migrans. METHODS: DNA isolates from sera of patients with erythema migrans were analyzed by nested polymerase chain reaction (PCR), amplifying a segment of flagellin gene with primers encompassing the conserved region of the gene. To screen PCR products for heterogeneity, we performed single-stranded conformation polymorphism (SSCP) analysis. The samples showing differences in SSCP patterns were sequenced, and the sequence compared in the GeneBank for sequence homology with known Borrelia burgdorferi genospecies. We also constructed phylogenetic tree of all known borrelial sequences. RESULTS: The nested PCR method using specially designed flagellin gene primers, achieved the sensitivity of 10 genome copies (0.01 pg of purified Borrelia burgdorferi DNA from culture) by dilution analysis. The assay specificity was confirmed by amplification of a part of the flagellin gene from different bacterial species. The primer pairs successfully amplified only Borrelia burgdorferi flagellin gene. The genome of Borrelia burgdorferi sensu lato was detected in the sera of all 10 tested patients with erythema migrans. Sequence data and phylogenetic analysis confirmed that all amplified samples belonged to Borrelia afzelii genospecies. CONCLUSION: Phylogenetic tree analysis placed the borrelial isolates together with Borrelia afzelii sequences into a single group. This finding was additionally supported by sequence homology analysis, which produced a homology score of 99%. In patients with erythema migrans who come from the northwest Croatia, an endemic area for Lyme borreliosis, Borrelia afzelii was the cause of skin manifestations of Lyme borreliosis.

Congenital pulmonary arteriovenous fistula: a rare cause of cyanosis in childhood.

Two children (both females) aged 15 months and 4 years are described as very rare cases of central cyanosis in childhood being caused by a congenital pulmonary arteriovenous fistula. The initial diagnosis was made based on cyanosis and chest radiographs, with normal physical, ECG, and radiological findings of the heart. They had no family history of the Rendu-Weber-Osler syndrome. The patients underwent cardiac catheterization and pulmonary angiography, where the diagnosis was confirmed. After the surgery, both were symptom-free, and had no evidence of the disease.

Percutaneous transluminal renal angioplasty (PTRA) as a method of therapy for renovascular hypertension in children.

The results of PTRA in treatment of renovascular hypertension in four children aged 5, 7, 13 and 15 are presented. All patients suffered from severe hypertension. Tests showed all of them to have fibromuscular dysplasia stenosis of the main renal artery and significant lateralization of renin levels. One suffered from associated polycystosis of kidneys and in another the renal artery stenosis was bilateral. In all patients successful patency was achieved. In one patient, the arterial pressure after PTRA was normalized, while in the others it was considerably improved. Two patients, tested 8 and 12 months after PTRA, were lost to further follow-up. In one of the remaining two, stenosis and hypertension reappeared 5 years after PTRA. After autotransplantation the patient was normotensive. In the other, also 5 years later, recurrent hypertension appeared related to the associated polycystosis.

[Primary adrenocortical micronodular dysplasia].

Two girls (11 and 13 years old) with Cushing's syndrome due to primary adrenocortical micronodular dysplasia (PAMD) are presented. High plasma cortisol concentrations, elevated urinary free cortisol and 17-ketogenic steroids excretion, in addition to low or normal plasma adrenocorticotropic hormone (ACTH) levels pointed towards independent adrenal cortisol hypersecretion. In both girls bilateral adrenalectomy was performed, followed by replacement therapy with glucocorticoids and mineralocorticoids. Pathohistological findings of otherwise enlarged adrenal glands, showed characteristic small nodules measuring 1-2 mm, composed of cells resembling those of zona fasciculata, with abundant, clear cytoplasm. Our younger patient fulfilled the criteria of "Carney complex", because beside PAMD she has had the lentigines.

[Direct communication of the pulmonary artery with the left atrium].

A rare communication between the right pulmonary artery and the left atrium in a 3.5-year-old girl is described. Cyanosis of a central type and a continuous murmur over the heart were presenting symptoms. Echocardiography revealed only excessive pulsations of the pulmonary artery, while catheterization pointed to an abnormal aneurysmal communication between the right pulmonary artery and the left atrium. At this point the O2 saturation was at the level of the left atrium. The communication was clinically classified as a type IV according to Nelson. After an unsuccessful attempt through a right thoracotomy, the ligature of this fistula has been performed in the second attempt through a median sternotomy and under complete extracorporeal circulation. Clinical course and review of literature of this rare anomaly of the heart are being presented.
