Normal pulsed wave Doppler echocardiographic parameters of Turkmen horses of Iran

Turkmen horse is one of the oldest and purest breeds in the world, but there is no information on Doppler echocardiographic parameters in this horse. In the present study, pulsed-wave [PW] Doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing Turkmen horses. No cardiac disease was detected with two-dimensional [2-D] real-time, M-mode, and colour flow mapping. Doppler echocardiographic parameters and indices of tricuspid, mitral, pulmonary and aortic flows were measured in this study. Tricuspid inflow velocities during rapid filling [E] and atrial contractions [A] were significantly higher than mitral inflow [P<0.05]. The Doppler waveforms, obtained from the aortic outflow, showed a significantly longer pre-ejection period [PEP] and shorter ejection time [ET] than the pulmonary artery waveforms [P=0.001 and P=0.028, respectively]. The time taken from the onset of the QRS complex to the onset of the A wave for tricuspid flow, pulmonary PEP, and pulmonary PEP/ET, had a significant positive correlation with age. These values can be used as standard and reference values for evaluation of cardiovascular disorders in Turkmen horse

Seroprevalence of Toxoplasma gondii infection in dogs in Tehran, Iran

Toxoplasma gondii infects a wide range of animals; felines are definitive hosts and other animals including the dogs are intermediate hosts. The aim of this study was to determine the seroprevalence of T. gondii infection in dogs in Tehran, capital of Iran and to investigate possible associated risk factors. Three hundreds ninety six serum samples were collected during 2007-8 from the dogs. Collected samples were tested using an indirect fluorescent antibody test [IFAT] in dilutions of 1:16 and more. All procedures were carried out in Shahrekord University, Iran. All the data were analyzed using SPSS software, qui square test with confidence interval of 0.95. From evaluated samples, 89 [22.47%] were positive in titers of at least 1:16. further evaluations in other dilutions showed positive results in dilutions of maximum 1:16, 1:32, 1:64, 1:128 and 1:256 in 38, 29, 15, 2 and 5 dogs respectively. Investigation of the role of risk factors showed no sex predisposition while infection rate was significantly higher in dogs older than one year old. Living places were of significant importance; infection rate was significantly higher in stray or guard dogs in compare with household dogs [P<0.05]. Relatively high seroprevalence of T. gondii infection in dogs in Tehran shows high environmental contamination. It is recommended that the dogs with suspected clinical signs be tested for T. gondii infection

Normal left ventricular systolic time intervals assessed by pulsed wave Doppler echocardiography in the Turkmen horse of Iran

The Turkmen horse is one of the oldest and purest breeds in the world. There is no information with regards to the normal echocardiographic parameters of this horse regarding to cardiac diseases. Pulsed-wave [PW] Doppler echocardiography was performed on 42 clinically normal 3-to 15-year-old racing Turkmen horses. There were 26 stallions and 16 mares. The left ventricular isovolumetric contraction time, pre-ejection period [PEP], and the left ventricular ejection time [LVET], were measured, and the values of the left ventricular total electromechanical systole [LVTES] and the PEP-to-LVET ratio were calculated. The most suitable window for the measurement of the aforementioned indices in PW Doppler echocardiography was the left parasternal window using the five-chamber apical view. The following values were acquired in PW Doppler echocardiography: PEP = 0.088 +/- 0.018 s; LVET = 0.445 +/- 0.031 s; LVTES - 0.533 +/- 0.032 s; and PEP-to-LVET = 0.199 +/- 0.046. These measurements can be used in the future as standard and reference values for the evaluation of cardiovascular disorders in the Turkmen horse

[Irritant contact dermatitis due to angustifolia]

A case of sever bullous irritant contact dermatitis in uncommon site in a 50 year-old woman secondary to contact with angustifolia fruit is reported. She developed multiple bullous lesions on anterior of her trunk. We found no prior clinical report of contact dermatitis due to Elaeagnus angustifolia. In a broad sense, Irritant contact dermatitis represents the cutaneous response to the physical and toxic effects of a wide range of environmental exposure. Irritant contact dermatitis has a spectrum of clinical features, ranging from a little dryness, redness or chapping through various type of eczematous to an acute caustic burn

[Case report - Orf followed by erythema multiforme]

Orf is a sheep disease due to infection with a parapoxvirus. The infection is mainly transmitted to man by direct contacts and seldomly by contaminated instruments. Infection in human results in a benign and self-limited disease, generally. Although, rare complications have been mentioned, this is a report about a case of orf with erythema multiforme in a 54 year old woman
