Influence of the uterine inflammatory response after insemination with frozen-thawed semen on serum concentrations of acute phase proteins in mares.

The aim of this study was to investigate the clinical relevance of measuring blood concentrations of serum amyloid A (SAA), haptoglobin (Hp) and fibrinogen (Fib) in horse reproductive management, and changes in response to artificial insemination (AI) with frozen-thawed semen. Standardbred mares (n=18) with different reproductive status (eight healthy mares in first postpartum oestrus, five healthy barren mares and five mares with endometritis) were inseminated with frozen-thawed semen. Endometritis was evaluated during oestrus by bacteriological culture, cytology and presence of ultrasonically visible intrauterine fluid during oestrus. Concentrations of SAA, Hp and Fib were analysed in the blood in every 48h during oestrus and until 5, 6 or 7 days after AI. The day of sampling and number of blood samples varied between mares because of length of the oestrus and time of AI. Changes in concentrations of SAA, Hp and Fib were evaluated based on the day of sampling regard to AI and classification of the mares. There were no differences in SAA, Hp and Fib concentrations over time before or after AI or between the groups of mares. The insemination of mares with frozen-thawed semen did not increase the plasma concentrations of SAA, Hp and Fib above clinical threshold concentration and there were no differences between susceptible or healthy mares.

Alopecia areata in Turkey: demographic and clinical features.

BACKGROUND: Alopecia areata is a complex genetic disease with still many unknown aspects, and many studies have been tried to find some clues about it. OBJECTIVE: We aimed to investigate the demographic and clinical characteristics of alopecia areata in Turkish patients. METHODS: Demographic data, localization, attack number in addition to some parameters such as disease duration, severity, age of onset, family history and ophiasis pattern were evaluated in 539 alopecia areata patients. RESULTS: The male to female ratio was 1.6:1. Occipital and beard-moustache areas were mostly affected. Positive family history was noticed in 24.1% of the patients. The age of onset was earlier in women than in men (P = 0.04). Severe forms showed more persistent (> or = 1 year) disease duration (P = 0.00). Ophiasis was more common in severe, long duration (> or = 1 year) and early onset (< or = 18 years) disease (P = 0.00 for all parameters). Childhood alopecia areata (< or = 18 years) was also associated with long duration of the disease (P = 0.016) and positive family history (P = 0.008) when compared with adult onset (> 18 years) alopecia areata.

Prevalence of oral lesions in 13- to 16-year-old students in Duzce, Turkey.

OBJECTIVE: The aim of this study was to determine the prevalence of oral lesions in 13- to 16-year-old students. METHODS: A cross-sectional survey was carried out on students in Duzce, a province in the western Black Sea region of Turkey. A total of 993 children aged between 13 and 16 from eight secondary schools were examined. Oral lesions with recurrent behavior, if observed, were recorded at the time of examination. Venous blood samples were obtained for detecting hemoglobin levels. RESULTS: Two hundred sixty adolescents (26.2%) were diagnosed with at least one oral mucosal lesion at the time of the examination. Thirteen different mucosal alterations were diagnosed, and the most common lesions were angular cheilitis (9%), linea alba (5.3%), and aphthous ulceration (3.6%). The correlation between occurrence of mucosal lesions and sex was not statistically significant (P > 0.05). Statistical evaluation of the data revealed a significant relationship only between the presence of angular cheilitis and anemia (P < 0.05). CONCLUSION: This study is the first epidemiologic study of oral mucosal lesions in adolescents in Turkey. Angular cheilitis was the only oral mucosal lesion that had a significant correlation with anemia.

Can sarcoidosis cause autoamputation of a finger phalanx?

Sarcoidosis is a multisystemic granulomatous disease. In the case presented, autoamputation of the distal phalanx of a little finger of the left hand was observed. The possibility of autodigital amputation as a result of sarcoidosis is discussed.

Persistent serpentine supravenous hyperpigmented eruption associated with docetaxel.

Various mucocutaneous reactions have been reported with the use of systemic docetaxel. We describe a 47-year-old man who developed a persistent serpentine supravenous hyperpigmented eruption (PSSHE), beginning at the site of docetaxel injection and spreading along the superficial venous network in the anterior aspect of the right forearm and distal arm. The eruption occurred after the first infusion of docetaxel following insufficient venous washing. A second infusion was administered through a vein in the other forearm, but this time, abundant venous washing was performed and a similar eruption did not occur. To our knowledge, this is the second report of docetaxel-induced supravenous discoloration and we discussed the terminology and mechanism of this unique reaction.

Non-Hodgkin's lymphoma and auricular hypoplasia: associated with juvenile colloid milium or ligneous conjunctivitis?

The exact nature of amyloid-like hyaline material deposits in the skin is not well understood in some disorders. Three of those--ligneous conjunctivitis, ligneous periodontitis and colloid milium--have been rarely reported in a same patient. We report a case of mucosal and skin deposits of an amyloid-like homogeneous material associated with non-Hodgkin's lymphoma and congenital auricular hypoplasia. We discussed and reviewed the literature on these unique associations to determine whether these are the same pathological process. We also noted whether this case represents a new syndrome or a coincidental association.

Habituation of auditory event-related potentials in patients with Behcet's disease.

Behcet's disease is a progressive and/or relapsing-remitting multisystem inflammatory disorder. Involvement of the central nervous system occurs in 10%-29% of cases with Behcet's disease. The aim of the present study was to assess the effect of repetitive auditory stimulations on event-related potentials (ERP) in patients with Behcet's without neurologic manifestations. The study was performed in 14 patients with Behcet's disease and 14 healthy volunteers. ERPs were recorded from Fz, Cz and Pz. The auditory ERPs test was continued until 20 artefact-free rare tones were averaged, which was accepted as one trial block. After six blocks were obtained in a sequential manner, the test was completed. According to the results of the present study, P300 latency changed in different manners over trial blocks in the two groups. P300 latency values showed a progressive increase in the controls; however this was not determined in the Behcet's group. Thus, habituation was not observed in the patient group. Because of the lack of habituation related to P300 latency, it may be thought that there is an insidious pathologic process in Behcet's disease without neurologic manifestation.

Sperm morphology in Estonian and Tori breed stallions.

The standard procedure for assessing the breeding potential of a stallion includes the parameter total number of spermatozoa classified as morphologically normal. This study investigated sperm morphology of fresh semen in randomly chosen Estonian (E, n = 8) and Tori (T, n = 7) breed stallions with proven fertility. Two ejaculates were examined from each stallion. An aliquot from each ejaculate was fixed in 1 mL formol-saline immediately after collection and examined with phase-contrast microscope at a magnification 1000x for all types of morphological abnormalities. Furthermore smears were prepared and stained according to Williams (carbolfuchsin-eosin) for a more detailed examination of the sperm heads with light microscope at a magnification 1000x. Analysis of variance was applied to the data, and results are presented as LSmeans (+/- SE). One T stallion that had a disturbance in the spermatogenesis and one 22-year-old E stallion were not included in the analyses. The T stallions had on average 57.5 +/- 4.1% and the E-stallions 74.4 +/- 3.8% morphologically normal spermatozoa (p = 0.012). In 4 of 7 T stallions and 7 of 8 E stallions both ejaculates had > 50% morphologically normal spermatozoa. There was a significant difference between breeds in mean percentage of proximal droplets (17.3 +/- 2.7% and 2.9 +/- 2.5% for T and E stallions, respectively; p = 0.003).

Bilateral multiple piloleiomyomas on the breast.

Piloleiomyomas are benign smooth muscle tumors arising from the erector pilorum muscles in the skin. They vary in size and number, and are often spontaneously painful or sensitive to touch and cold. In this paper, we present two young female patients who have multiple breast piloleiomyoma and discuss the related findings.

Measurement of epidermal thickness in a patient with psoriasis by computer-supported image analysis

The aim of the present study was to measure full epidermal thickness, stratum corneum thickness, rete length, dermal papilla widening and suprapapillary epidermal thickness in psoriasis patients using a light microscope and computer-supported image analysis. The data obtained were analyzed in terms of patient age, type of psoriasis, total body surface area involvement, scalp and nail involvement, duration of psoriasis, and family history of the disease. The study was conducted on 64 patients and 57 controls whose skin biopsies were examined by light microscopy. The acquired microscopic images were transferred to a computer and measurements were made using image analysis. The skin biopsies, taken from different body areas, were examined for different parameters such as epidermal, corneal and suprapapillary epidermal thickness. The most prominent increase in thickness was detected in the palmar region. Corneal thickness was more pronounced in patients with scalp involvement than in patients without scalp involvement (t = -2.651, P = 0.008). The most prominent increase in rete length was observed in the knees (median: 491 æm, t = 10.117, P = 0.000). The difference in rete length between patients with a positive and a negative family history was significant (t = -3.334, P = 0.03), being 27 percent greater in psoriasis patients without a family history. The differences in dermal papilla distances among patients were very small. We conclude that microscope-supported thickness measurements provide objective results.

Testicular measurements and daily sperm output of Tori and Estonian breed stallions.

Evaluation of testicular measurements and daily sperm output (DSO) yields valuable information for predicting the reproductive capacity of stallions. The present study evaluated testicular measurements (height, length, width and circumference) and DSO of eight Tori and eight Estonian breed stallions. One ejaculate of semen was collected daily for 10 subsequent days from each stallion. The gel-free volume of semen was measured with a graduated glass cylinder and the sperm concentration was assessed with a Chorjajev chamber. The volume of gel-free fraction was multiplied by the sperm concentration to give the total number of spermatozoa (TSN). The DSO was calculated as mean TSN of collection on days 8-10 in Tori breed stallions and on days 4-10 in Estonian breed stallions. The DSO of Tori breed stallions was 12.9 x 109 spermatozoa and of Estonian breed stallions 4.5 x 109 spermatozoa (p < 0.001). Testicular measurements (in cm) 1 day after the last semen collection were as follows: left testis- height 7.3, length 10.4 and width 7.3 in Tori breed stallions, and 5.9, 8.1 and 5.9, respectively, in Estonian breed stallions; right testis- height 7.4, length 10.6 and width 7.4 in Tori breed stallions, and 5.5, 7.4 and 5.3, respectively, in Estonian breed stallions. All these testicular measurements were significantly smaller in Estonian than in Tori breed stallions (p < 0.001). Testicular circumference was 45.4 and 35.4 cm in Tori and Estonian breed stallions, respectively (p < 0.001). The testicular circumference was correlated with DSO in both Estonian (p < 0.05) and Tori breed stallions (p = 0.071). The results give us valuable information on the reproductive capacity of Tori and Estonian breed stallions.

Dyskeratosis congenita associated with three malignancies.

Dyskeratosis congenita is a rare inheritable disorder characterized by abnormalities of the skin, nails and oral mucosa. Aplastic anaemia resulting from bone marrow hypoplasia is a frequent cause of death. Squamous cell carcinoma developing from leukoplakia and visceral malignancies are other complications of the disease. We report here a case of dyskeratosis congenita in a man who developed three neoplasias of different systems over a period of many years. Squamous cell carcinoma and gastric adenocarcinoma manifested 17 years after the man was diagnosed with Hodgkin's disease.

Evaluation of cryopreserved stallion semen from Tori and Estonian breeds using CASA and flow cytometry.

Methods to evaluate the quality of frozen-thawed stallion semen are still needed, particularly those considering the sperm function. The present study evaluated sperm motility, membrane and acrosome integrity and the capacitation status of frozen-thawed spermatozoa from seven Tori and six Estonian breed stallions by way of computer assisted sperm analysis (CASA), a triple fluorophore stain combination and Merocyanine 540, respectively, the latter ones using flow cytometry. Two ejaculates from each stallion were cryopreserved using the Hannover method in 0.5 ml plastic straws. Two straws per ejaculate per stallion were thawed at 37 degrees C for 30s. Motility was analysed with CASA immediately after thawing, while for flow cytometry spermatozoa were cleansed by 70:40% Percoll discontinuous density gradient separation before analysed for sperm viability, acrosome integrity (stained with SNARF, PI and FITC-PSA) and capacitation status (stained with Merocyanine 540/Yo-Pro-1). Results (as least square means) were as follows: the motility of frozen-thawed semen was 43.4% for Tori stallions and 42.3% for Estonian stallions (P>0.05). After Percoll separation 79.3% of the spermatozoa from Tori stallions had intact acrosomes and 1.7% of them showed early signs of capacitation. The same parameters for Estonian stallions were 84.5 and 2.3%, respectively. There were no statistically significant differences between breeds or ejaculates within breed for any evaluated parameter. We conclude that triple staining and flow cytometry are valuable techniques to evaluate frozen-thawed stallion spermatozoa, and that no differences in quality of frozen semen were registered between Tori and Estonian breed stallions, allowing implementation of this technology in the Estonian horse population.
