Abstract

Disseminated superficial actinic porokeratosis is the most common form of porokeratosis in adults, which develops in the third or fourth decade of life, but may also occur later or earlier, more frequently in females, particularly in countries with high sun exposure. Lesions are numerous, uniform, superficial with central atrophy, demarcated by a distinct peripheral ridge, and usually found on sun exposed areas or elsewhere. The disease is inherited as an autosomal dominant condition. We present a 57-year-old retired woman. Her initial skin changes, affecting the face, developed in her thirties, and they have not changed their features since. In the following years, changes developed on the extensor surface of her arms and legs, with more prominent erythema, and then also on other parts of the body, including palms and soles, presenting as dark brown pigmented patches. Her mother had similar changes, and her daughter, who lives abroad, also has them. On examination, the patient presented with facial lesions, patches 2-3 mm wide, with peripheral hyperpigmentation and a pale center. There were multiple, 2-3 mm wide, dark brown lesions on the extremities and trunk. The lesions were either flat or with atrophic center with darker filiform corneal rim. Pathohistolgical examination revealed a "cornoid lamella", which is pathognomonic for the diagnosis of porokeratosis. Auxiliary diagnostic methods were also used - dermoscopy and Gentian violet staining. The patient was advised to avoid sun exposure and to apply photoprotective sunscreens. In conclusion, this is a case report of a disseminated superficial actinic porokeratosis that affected three generations of a family. Our patient developed lesions on palms and soles as well. A review of available world literature shows that this is the second case report of disseminated superficial actinic porokeratosis with palmoplantar involvement.

Abstract

Sarcoidosis is an acquired idiopathic granulomatous disease, which is characterized by noncaseating epithelioid granulomas in organs and tissues. Most frequently it affects the lungs, liver, lymph nodes, skin, eyes and other organs. The cutaneous lesions appear in 20 - 30% of patients with systemic manifestations, and in 25% of them they appear without systemic manifestations. Based on the histopathological characteristics, cutaneous lesions are divided into specific, characterized by cutaneous granuloma, and non-specific, which are not granulomatous. Moreover, they can be classified as typical and atypical. We are presenting a female patient with unilateral hilar calcification of the lungs, who exhibited plaque skin lesions typical for sarcoidosis, with a specific granulomatous histology and a favorable response to corticosteroid and antimalarial therapy.

Abstract

Background

There are several potential risk factors in patients with a hip fracture for a higher rate of mortality that include: comorbid disorders, poor general health, age, male gender, poor mobility prior to injury, type of fracture, poor cognitive status, place of residence. The aim of this study was to assess the influence of potential risk factors for six-month mortality in hip fracture patients.

Methods

The study included all patients with a hip fracture older than 65 who had been admitted to the Clinic for orthopaedic surgery during one year. One hundred and ninety-two patients were included in the study.

Results

Six months after admission due to a hip fracture, 48 patients had died (6-month mortality rate was 25%). The deceased were statistically older than the patients who had survived. Univariate regression analysis indicated that six variables had a significant effect on hip fracture patients’ survival: age, mobility prior to the fracture, poor cognitive status, activity of daily living, comorbidities and the place where they had fallen. Multivariate regression modelling showed that the following factors were independently associated with mortality at 6 months post fracture: poor cognitive status, poor mobility prior to the fracture, comorbid disease.

Conclusion

Poor cognitive status appeared to be the strongest mortality predictor. The employment of brief tests for cognitive status evaluation would enable orthopaedists to have good criteria for the choice of treatment for each patient screened.

Abstract

The paper presents clinical diagnostic approaches and therapeutic effects of a specific protocol for the treatment of dogs with cardiovascular dirofilariasis in the Belgrade City (Serbia) territory. The study involved 50 privately owned dogs of different breeds, gender, and age, all showing signs of cardio - respiratory disorders. In addition to a general physical examination, blood tests were done to detect microfilaria and adult forms, and X-ray, ECG, and echocardiography were performed as well. At the first examination, 34 out of 50 examined dogs were positive for microfilaria and adult forms. Because of a lack of drug used as „the golden standard“ in dirofilariasis treatment, it involved a combination of doxycycline (10 mg/kg) and ivermectin (6 μg/kg) supported with Advocate - Bayer spot-on. After six months, the first control was performed while continuing treatment with the aforesaid protocol, and the second control was performed after 12 months. Of the 34 treated dogs, all were negative for microfilaria, as early as after the first six months of the treatment (100%). One dog was positive for adult forms of the parasite after six and 12 months. In echocardiography and X-ray examination after 12 months, six dogs showed evident chronic changes. At controls conducted at sixth month and at one year, the implemented therapy was successful in 97.05% (33/34) of primarily infected dogs.

Abstract

Keratitis, ichthyosis and deafness (KID) syndrome is a rare congenital ectodermal dysplasia characterized by ichthyosiform hyperkeratosis of the skin, neurosensory hearing loss and vascularizing keratitis. It is inherited as an autosomal dominant trait, now known to be due to mutations in the connexin gene.

This paper presents a case of a 20-year-old male patient with erythrokeratodermia and mild scaling since birth. He presented mild hearing impairment at the age of two and often suffered from eye inflammations. On admission, his clinical picture was typical of KID syndrome with erythrokeratodermia, neurosensory deafness, vascularizing keratitis, alopecia, palmoplantar keratosis, and nail dystrophy. The patient also had a history of recurrent infections, especially bacterial and candidal infections of the skin, auditory canals and eyes. Despite extensive skin, ocular, ear and hair manifestations, his physical and psychomotor growth and development were normal.

Adjuvant balneotherapy in Prolom Spa, along with emollient creams, significantly reduced cutaneous manifestations in our patient.

Abstract

The influence of using formic, oxalic, citric, tartaric, hydrochloric, nitric, sulphuric and phosphoric acid for dyebath pH adjustment was investigated upon the dyeing of polyester fabric with CI Disperse Yellow 60. The positions of colour in CIELab coordinates of the samples dyed with the addition of tested acids were assessed and compared to those dyed with the addition of acetic acid. It was found that the differences in dyeabilities obtained with the addition of citric, oxalic, hydrochloric, nitric and sulphuric acid are entirely acceptable according to both M&S 83A and CMC (2:1) standards in comparison to the dyeability obtained with the addition of acetic acid.

Abstract

Introduction: The aim of the study was to determine the prevalence of respiratory capillariosis in red foxes (Vulpes vulpes) in some regions of Serbia.

Material and Methods: The study was conducted on 102 foxes in six epizootiological regions of Serbia, during the hunting season between 2008 and 2012.

Results: The presence of respiratory capillariosis in all tested epizootiological regions was confirmed. The E. aerophilus nematode was detected with overall prevalence of 49.02%. The diagnosis of E. aerophilus infection was confirmed by the determination of morphological characteristics of adult parasites found at necropsy and the trichurid egg types collected from the bronchial lavage and the content of the intestine.

Conclusion: The presented results contribute to better understanding of the epidemiology of this nematodosis in Serbia. However, the high prevalence of capillaries in tested foxes, demonstrated in all explored areas, might suggest that foxes from other regions in Serbia may also be infected. The fact that domestic carnivores and humans can also be infected enhances the importance of the overall epidemiological status. To establish the relevant prevalence of respiratory capillariosis, further investigations and continous monitoring of parasitic fauna of carnivores are needed in the whole country.

Summary

Background: Oxidized low density lipoprotein (ox-LDL) and high-sensitive C-reactive protein (hs-CRP) are elevated in diabetes mellitus (DM) and associated with accelerated atherosclerosis. Little is known about their dynamics in the acute phase of ST segment elevation myocardial infarction (STEMI), especially in relation to the presence of DM and pre-diabetes (pre-DM). This study aimed to analyze timedependent changes in ox-LDL and hs-CRP regarding the presence of pre-DM and DM in STEMI patients treated by primary percutaneous coronary intervention (pPCI).

Methods: In 103 consecutive patients with the first anterior STEMI ox-LDL and hs-CRP were measured before pPCI, on day 2 and day 7 after pPCI.

Results: Patients were classified into: non-diabetics, pre-diabetics and diabetics. In each group the maximal ox-LDL concentration was found on admission, decreased on day 2 and reached the lowest values on day 7 (p<0.001). Diabetics had the highest ox-LDL concentrations compared to pre-diabetics and non-diabetics (on admission: p=0.028, on day 2: p=0.056, on day 7: p=0.004). hs-CRP concentration rose from admission, reached its peak on day 2 and decreased on day 7, in each group (p<0.001). Significant differences in hs-CRP concentrations were found between non-diabetics and pre-diabetics on admission (p=0.018) and day 2 (p=0.026). In a multivariate analysis DM was an independent determinant of high ox-LDL concentrations. Both ox-LDL and hs-CRP significantly correlated with Killip class, left ventricular ejection fraction, NT-proBNP and peak troponin I.

Conclusions: In patients with the first STEMI treated by pPCI there were significant differences in ox-LDL and hs-CRP concentrations between non-diabetics, pre-diabetics and diabetics. Ox-LDL and hs-CRP concentrations were related to heart failure parameters.
