Pediatric hydatid cyst with ventricular aneurysm and surgical treatment with dor procedure, case report.

BACKGROUND: Cardiac involvement of hydatid cyst disease (HCD) is a rare presentation but may lead to life-threatening complications such as cyst rupture and should be treated surgically. METHODS: A 10-year-old male patient with cranial and complicated cardiac HCD lesions that caused lower extremity peripheral arterial occlusion and aneurysmatic dilatation in the left ventricular apex is presented. RESULTS: Although the patient was in the pediatric age group, the Dor procedure was successfully applied to preserve the ventricular geometry. The Dor procedure for a ventricular aneurysm caused by a cardiac hydatid cyst (CHC) was rarely applied in the pediatric age group. CONCLUSION: In conclusion, this case differs from other CHCs previously reported in the literature due to the advanced stage of the disease, atypical clinical presentation, and rare complications despite the young age of the case. The surgical method used in treating the patient makes the subject more interesting.

Mental well-being and social support perceptions of nurses working in a Covid-19 pandemic hospital.

PURPOSE: This study was conducted to determine the mental well-being and social support perceptions of nurses working in a Covid-19 pandemic hospital. DESIGN AND METHODS: This study used a cross sectional design. The sample included 333 volunteer nurses. FINDINGS: Based on the marital and income statuses of the nurses, there was a significant difference between the multidimensional scale of perceived social support family subscale (p < 0.05). There was a positive, weakly significant relationship between the nurses' mental well-being and their perception of social support (r = 0.381; p < 0.05). PRACTICE IMPLICATIONS: In conclusion, protective measures must be increased and social networks must be promoted to increase the mental well-being and social support levels of nurses.

A serological investigation of Bovine enterovirus-1, Bovine herpesvirus-1, Bovine viral diarrhea virus, and Parainfluenza-3 infections in camelsin Western Turkey.

Camels (Camelus dromedarius) are bred in Western Turkey, particularly in the province of Aydin, for touristic, social and cultural purposes. Bovine enterovirus­1 (BEV­1), Bovine herpesvirus type­1 (BHV­1), Bovine viral diarrhea virus (BVDV), and Parainfluenza­3 (PI­3) virus infections are significant causes of health and/or economic concerns in several animal species. These agents have not been investigated in the camel population in Turkey. The objective of this study was to serologically investigate the presence and infection rates of these viruses in camels in Aydin province, Western Turkey. Ninety­two serum samples were taken from clinically healthy camels that were kept in private farms or brought to the local slaughterhouses. Serum neutralization test was performed to assess the presence and the titers of specific antibodies against BEV­1, BHV­1, BVDV, and PI­3 virus in camel sera. Of the 92 camels tested, 30 (32.61%), 2 (2.17%), 54 (58.7%), and 20 (21.74%) were seropositive for BEV­1, BHV­1, BVDV, and PI­3, respectively. These results suggest that, except for BHV­1, these viral infections are common among camels in Western Turkey. To our knowledge, this the first comprehensive, large­scale study investigating these viral infections in camels in Turkey.

A study regarding bovine enterovirus type 1 infection in domestic animals and humans: An evaluation from the zoonotic aspect.

Bovine enteroviruses (BEV) are members of Enterovirus genus of the family Picornaviridae. BEV1 has a broad host spectrum, including humans. The virus usually causes subclinical infection, but fatal/severe cases have also been reported in different animal species. There is quite limited data regarding BEV1 in humans. The purpose of this study is to investigate human infection and to identify possible risk factors for viral exposure. For this purpose, blood serum samples (n=1,526) were collected from a city center and nearby villagers simultaneously from humans and farm animals in Elazig province in Eastern Anatolia. As a result of serum neutralisation test, BEV1 specific antibody presence detected in cattle was 85.3% (163/191), 73.5% in donkeys (64/87), 71.8% in goats (115/160), 46.5% in sheep (93/200), 43.9% in horses (40/91), 41.3% in dogs (19/46) and 33% in humans (248/751). Although a high contamination potential was mentioned for people living in rural areas, it was determined that infection rates in rural areas (31.6%) and urban centers (32.2%) were very close. There was no difference according to sex. Viral exposure is higher in the 40 to 70 age range. In addition, the serological evidence of the infection in donkeys was identified for the first time with this study.

The role of goats as reservoir hosts for bovine herpes virus 1 under field conditions.

Bovine herpesvirus 1 (BoHV1) is the cause of economically significant viral infections in cattle. Respiratory symptoms associated with the infection are known as Infectious Bovine Rhinotracheitis (IBR). Sheep and goats are less sensitive to the infection although their role in inter-species viral transmission under field conditions is subject to controversy. The objective of this study was to investigate seroprevalence of BoHV1 infections in cattle, sheep, and goats raised together for at least a year. Blood serum samples were taken from 226 cattle, 1.053 sheep, and 277 goats from 17 small- to medium-scale farms. BoHV1-specific antibody presence and titers were determined using virus neutralization test. In total, 73 of the 226 cattle (32.3%) were seropositive. The infection was detected in 13 of the 17 farms. Infection rates ranged from 5.8 to 88.8%. Only one of the 1053 sheep (0.09%) was seropositive. However, 58 of the 277 (20.9%) goats were seropositive. Goat samples taken from 8 of the 17 farms were seropositive with infection rates ranging from 17 to 38.9%. Statistical analysis showed a significant correlation in infection rates between cattle and goats but not sheep. These results suggest that goats may be more sensitive to the BHV1 infection than sheep and the role of goats as possible reservoirs for BoHV1 in the control and eradication of BHV1 in cattle should be considered in future studies.

The first serological evidence for Rift Valley fever infection in the camel, goitered gazelle and Anatolian water buffaloes in Turkey.

Rift valley fever (RVF), a vector-borne zoonotic disease, is caused by a phlebovirus (family Bunyaviridae). The virus was initially characterized approximately 80 years ago in Kenya and disseminated to many countries in the continental Africa, Saudi Arabia, and Yemen. The infection has not been reported in Turkey. In this study, blood serum samples collected from camel (Camelus dromedairus), goitered gazelle (Gazella subgutturosa subgutturosa), and buffaloes (Bubalus bubalis linneaus) from 2000 to 2006 were investigated for RVF using C-ELISA. Camel samples (n = 72) were obtained from private small enterprises in Aydin province in theAegean region. Gazella samples (82) were taken from the biggest captive gazelle herd in Sanliurfa province in the southeast Anatolia. Buffalo samples were collected mostly from small private family type farms in Afyon (168), Amasya (80), Samsun (69), Ankara (35), Sivas (21), Tokat (19), Konya (10), and Elazig (8) provinces in the central, north, west, and east Anatolia. All of the gazella samples were negative; whereas, one of the 71 camel samples (1.3%) was positive for RVF-specific antibodies. Buffalos from Sivas, Tokat, Konya, and Elazig provinces were negative. However, 35 of the 410 samples (8.5%) from rural areas in the following four provinces were positive: Amasya (12/80, 15%), Ankara (5/35, 14.2%), Samsun (8/69, 11.5%), and Afyon (10/168, 5.9%). To our knowledge, this is the first report of presence of RVF infection in Turkey.

Aortic valve replacement for papillary fibroelastoma.

Surgery is indicated for symptomatic patients with papillary fibroelastomas (PFE) on the aortic valve. The valve is commonly spared during tumor excision. Rarely, aortic valve replacement (AVR) is needed. We present a case requiring AVR for an aortic valve PFE and review the literature to determine the risk factors for failure of aortic valve-sparing techniques in patients with PFE.

Prevalence of bovine viral diarrhoea, bovine herpesvirus type 1 and 4 infections in repeat breeding cows in Western Turkey / Prevalência de infecções por vírus da diarreia viral bovina e herpesvírus tipos 1 e 4 em fêmeas bovinas repetidoras do cio na região oeste da Turquia

Bovine Viral Diarrhoea Virus, Infectious Bovine Rhinotracheitis and Bovine Herpesvirus Type 4 infections are widelyknown viral infections as the reproductive system pathogen in cattle. The purpose of this study was to investigate thepresence and prevalence of these infections in Repeat Breeding diagnosed cows. A total of 139 blood samples werecollected from nine different dairy herds in Western Turkey. All sampled animals were clinically healthy but not becomepregnant even though they were three to eleven times artificially inseminated. The samples were controlled serologicallyfor BHV1 and BHV4 using ELISA test, 2% and 3.9% proportions were detected, respectively. These values were foundto be very low in comparison to other studies in Turkey. Out of 139, 81 (58.2%) cows were found to be seropositive forBVDV, and the percentage was above the 70% in six herds. BVD antigen was detected in two animals in a herd with71.4% antibody rates. Antigen positive animals were sampled and tested again four weeks later and persistent viremiawere confirmed. In conclusion, BVDV infection may be responsible for repeat breeding in studied herds

Infecções por Vírus da Diarréia Viral Bovina (BVDV), Vírus da Rinotraqueíte Infecciosa Bovina (BHV-1) e HerpesvírusTipo 4 (BHV-4) são amplamente reconhecidas como infecções do trato reprodutivo em bovinos. O objetivo desteestudo foi investigar a presença e a prevalência destas infecções em fêmeas bovinas repetidoras de cio. Um total de 139amostras de sangue foi colhido de nove diferentes propriedades leiteiras na região Oeste da Turquia. Todos os animaisamostrados estavam clinicamente saudáveis, embora não tenham sido enxertados por inseminação artificial após trêsa onze tentativas. As amostras de soro foram testadas por método ELISA para detecção de anticorpos anti-BHV-1 eBHV-4, e 2,0 e 3,9% das amostras, respectivamente, foram consideradas positivas. Estes valores foram consideradosbaixos quando comparados com os de outros estudos na Turquia. De 139 amostras, 81 (58,2%) foram positivas para apresença de anticorpos anti-BVDV e mais de 70% das propriedades foram reveladas positivas. O antígeno de BVDVfoi detectado em dois animais em uma propriedade em que 71,4% dos animais eram soropositivos. Animais positivospara a presença de antígenos foram amostrados e testados novamente quatro semanas depois e viremia persistente foidetectada. Concluindo, infecção por BVDV pode ser responsável pelas perdas reprodutivas nas propriedades estudadas

Seroprevalance of peste des petits ruminants (PPR) in goitered gazelle (Gazella subgutturosa subgutturosa) in Turkey.

Gazella subgutturosa subgutturosa (goitered gazelle) is a native species of Anatolia. Because of the risk of extinction, captured gazelles have been taken under protection in a restricted area at the Ceylanpinar state farm, Southeast Anatolia, Turkey. Peste des petits ruminants virus (PPRV) infection had been detected previously in domestic ruminant species in this region, like in many other parts of Turkey. In this study, serum samples from 82 goitered gazelle were tested using competitive enzyme-linked immunosorbent assay (c-ELISA). Based on the test results, PPRV-specific antibodies were detected in 10 gazelles (12%). All c-ELISA-positive sera were confirmed by virus neutralization test.

The possible role of bovine herpesvirus type-4 infection in cow infertility.

Experimental and field studies have proven that the bovine herpesvirus type-4 (BHV-4) infection leads to various reproductive system problems. In this study, the role of BHV-4 infection in repeat breeding was investigated serologically. Eighty-four samples were obtained from repeat-breeding diagnosed cows in two organized dairy herds; an equal number of healthy cows were sampled from the same farms. The rest of the samples (105) were obtained from reproductively normal cows that were breeding in 18 small enterprises as a control group. The seropositivity proportion in repeat-breeding diagnosed cows was found to be significantly higher (69% (58/84)) than other cows (44% (37/84)) on the same farms. The lowest antibody positivity value for BHV-4 was detected as 24.7% (26/105) in the samples from family-type small farms. The odds ratio (OR) value was calculated as 2.834 in repeat-breeding diagnosed and healthy cows on the same farms, while 6.778 was determined in cows with and without reproductive problems on organized farms compared to small farms. As a result, the BHV-4 infection can be considered one of the reasons for repeat breeding besides other reproductive disorders.

A serologic investigation of epizootic hemorrhagic disease virus (EHDV) in cattle and gazella subgutturosa subgutturosa in Turkey.

Epizootic hemorrhagic disease virus (EHDV) is a vector-borne disease of ruminants disseminated in the tropic and subtropic zone of the world. Gazella subgutturosa subgutturosa (goitered gazelle) is native species of Anatolia. Due to risk of extinction, captured gazelles have been taken under protection in a restricted area at Ceylanpinar state farm. In this study, the presence of EHDV was investigated serologically in 82 goitered gazelle and 399 cattle. Seropositivity rates in goitered gazelle and cattle were detected as 2.43% and 3.50%, respectively.

Synthesis, cytotoxicity, and DNA interactions of new cisplatin analogues containing substituted benzimidazole ligands.

Six new platinum(II) complexes with 1-H or methyl-2-chloromethyl or acetoxymethyl or 2'-hydroxyethylbenzimidazole carrier ligands were synthesized and evaluated for their reactivity against model nucleophile I(-), cellular uptake, and in vitro antiproliferative activities against the human MCF-7 breast and HeLa cervix cancer cell lines. The effect of the compounds on pBR322 plasmid DNA was studied by gel electrophoretic mobility measurements. Flow cytometric analysis was also carried out to study the effect of representative compounds 1 and 2, bearing 2-chloromethyl or -acetoxymethylbenzimidazole carrier ligands, on the cell cycle distribution of MCF-7 and HeLa cells, respectively. In general, it was found that Pt(II) complexes were less cytotoxic than cisplatin and were comparable to carboplatin. The results of the plasmid DNA interaction and the restriction studies suggest that changing the chemical structure of the benzimidazole ligands may modulate DNA binding mode and the sequence selectivity. Compounds 1 and 2 had no significant effect on the cell cycle profile of the cells used. However, compound 2 induced a significant increase in the SubG1 cell population at a concentration of 20 microM.

Synthesis, cytotoxic activity on MCF-7 cell line and mutagenic activity of platinum(II) complexes with 2-substituted benzimidazole ligands.

Four Pt(II) complexes with 2-H/or-methyl/or-aminomethylbenzimidazole or 1,2-dimethylbenzimidazole ligands as "non-leaving groups" were synthesized and their antiproliferative properties were tested against the human MCF-7 breast cancer cell line. The mutagenic potentials of the complexes were tested in Salmonella typhimurium strains TA 98 and TA 100 in the absence of S9 rat liver fraction. In general, Pt(II) complexes tested which were found to be less active than cisplatin, exhibited moderate in vitro cytotoxic activity on MCF-7 cell line. Among the complexes tested, Pt(II) complex with 2-aminomethylbenzimidazole ligand was found to be highly mutagenic in S. typhimurium TA 98 and low mutagenic in S. typhimurium TA 100. Pt(II) complex with 1,2-dimethylbenzimidazole was mutagenic only in S. typhimurium TA 98. The other two complexes were found to be non-mutagen in both strains.
