Molecular detection of crimean-congo hemorrhagic fever virus (CCHFV)in tick samples but not in blood and milk samples of domestic ruminant species (cattle, sheep and goat) in northern Turkey

Crimean Congo Hemorrhagic Fever (CCHF) is an important disease. The objective of this study was to investigate the presence / prevalence of CCHFV in tick and milk and blood samples of domestic ruminant (cattle, sheep and goat) in Resadiye town of Tokat province, where the disease is endemic. Although no virus RNA was found from whole blood and milk samples, it was detected in 10 of 78 (12.8%) tick pools. Viral loads ranged from 4.8x104 copies/ml to 2.66x109 copies/ml. Out of 171 serum samples examined, 113 (66.1%) were found to be positive for CCHFV. In conclusion, it was revealed that the prevalence of CCHFV was more common in small ruminants than in cattle. It is an important result in terms of public health that virus cannot be detected. The detection of virus RNA in tick samples shows that CCHFV is still endemic in domestic animals.

An investigation of the seroprevalence of CrimeanCongo Hemorrhagic Fever and Lumpy Skin Disease in domesticated water buffaloes in northern Turkey

This study was conducted in Samsun Province of Turkey to investigate the serological status of domesticated water buffaloes for both Crimean-Congo Hemorrhagic Fever (CCHF) and Lumpy Skin Disease (LSD). Serum was collected from a total of 272 water buffaloes from different age groups and both genders; of the total, 48.1% had been vaccinated against LSD with heterologous sheep-goat pox vaccine. The serum samples were individually assessed by using a commercial ID screen enzyme-linked immune-sorbent assay (ELISA) to detect neutralizing antibodies against both CCHF virus and LSD virus. All 272 buffaloes were negative for antibodies against the CCHF virus. All the unvaccinated buffaloes (141) were seronegative for LSD virus but of the 131 vaccinated buffaloes, 10 (7.6%) were seropositive for the LSD virus. In addition, 8.6% of vaccinated animals age >1 year old were seropositive for LSD, whereas the seropositivity was 5.1% for the animals age <= 1 year old. There was no significant difference for seropositivity between male and female animals in the >1 year old or <= 1 year old age groups. When seroprevalances for LSD in the tested water buffaloes are evaluated by gender, there was a significant difference between females (8.6%) and males (0%) in the <1 year old water buffaloes (X²=20.24; P<0.001). Separately, the results of this study indicate that Bafra district water buffaloes are not infected by CCHFV and LSDV and some of the buffaloes that vaccinated with LSDV did not develop sufficient antibodies to protect them after they were vaccinated for the LSD virus. Furthermore, the authors of this study conclude that both the commercially produced vaccine that is currently administered and the vaccination strategy have to be urgently evaluated by the veterinary authorities in Turkey. This is essential in order to combat the spread of LSD virus infection with an effective vaccine and a comprehensive management strategy across Turkey.

The first serological report for genotype C bovine parainfluenza 3 virus in ruminant species of mid-northen Turkey: Traces from the past

Bovine parainfluenza 3 virus (BPI3V)is one of the most important respiratory pathogens and a leading cause of serious respiratory illnesses in cattle, both independent of and in connection with other pathogens involved in the bovine respiratory disease complex (BRDC). In this study, we aimed to identify the historical circulation of genotype C bovine BPI3V (BPI3Vc) in Turkey using the archival serum samples of domestic ruminants that had been collected from six provinces of northern Anatolia in Turkey between 2009-2010. A total of 896 sera from cattle (n=442), sheep (n=330), and goats (n=124) were randomly selected and screened with a virus neutralization test in order to detect antibodies for BPI3Vc. The overall seropositivity rate was 21.09%, with seropositivity rates for cattle, sheep, and goats of 21.04%, 20.00%, and 24.19%, respectively. Neutralizing antibody titers for selected samples ranged between 1/4 to 1/512. This study represents the first serological study conducted using the first BPI3V isolate of Turkey.

Efficacy of polishing kits on the surface roughness and color stability of different composite resins

OBJECTIVE

Different polishing kits may have different effects on the composite resin surfaces. The aim of this study was to evaluate the surface roughness and color stability of four different composites which was applied different polishing technique.

MATERIALS AND METHODS

Thirty specimens were made for each composite resin group (nanohybrid, GrandioSo-GS; nanohybrid, Clearfil Majesty Esthetic-CME; hybrid, Valux Plus-VP; micro-hybrid, Ruby Comp-RC; [15 mm in diameter and 2 mm height]), with the different monomer composition and particle size from a total of 120 specimens. Each composite group was divided into three subgroups (n = 10). The first subgroup of the each composite subgroups served as control (C) and had no surface treatment. The second subgroup of the each composite resin groups was polished with finishing discs (Bisco Finishing Discs; Bisco Inc., Schaumburg, IL, USA). The third subgroup of the each composite resin was polished with polishing wheel (Enhance and PoGo, Dentsply, Konstanz, Germany). The surface roughness and the color differences measurement of the specimens were made and recorded. The data were compared using Kruskal-Wallis test, and regression analysis was used in order to examine the correlation between surface roughness and color differences of the specimens (α = 0.05).

RESULTS

The Kruskal-Wallis test indicated significant difference among the composite resins in terms of ΔE (P < 0.05), and there was no statistically significant difference among composite resins in terms of surface roughness (P > 0.05). Result of the regression analysis indicated statistically significant correlation between Ra and ΔE values (P < 0.05, r2 = 0.74).

CONCLUSION

The findings of the present study have clinical relevance in the choice of polishing kits used.

Esthetic outcomes after immediate and late implant loading for a single missing tooth in the anterior maxilla

Objective

This study compared the esthetic outcomes of 1-year follow-up of immediate and late implant loading after implant restoration of a single tooth in the anterior maxilla.

Materials and Methods

A total of 33 patients with missing teeth in the anterior maxilla (Central = 8/lateral = 22/canine = 3) were enrolled in this study (18 immediate loading and 15 late loading). At after cementation, 1, 3, 6, and 12 months photographs were taken of anterior maxilla. The photographs were assessed using pink esthetic score (PES) which consists of seven variables. All PES data were analyzed with independent sample t-tests and repeated measures ANOVAs.

Results

PES values increased significantly in both groups at the 1-year follow-up (P > 0.05). There was no statistically significant difference between the immediate and late loading groups at any time point (P > 0.05).

Conclusions

Within the limitation of this study, immediate loading did not have a negative effect on esthetics.

Prosthetic rehabilitation of a patient with a resected right temporomandibular joint

This case report presents the prosthodontic rehabilitation of a patient with a resected right mandible, caused by an accident. Right condyle, ramus, and the posterior part of ramus were affected by the accident. These structures were resected, and the mandible was positioned toward the surgical area and a facial asymmetry was occurred. The patient was treated with a bar-retained maxillar denture with a guide ramp and an implant-supported fixed mandibular prosthesis.

Pityriasis rosea-like adverse reaction to atenolol

A 56-year-old female patient was presented with diffuse, bright red to violet colour, scaly patches on trunk and extremities after using a hypertension drug, atenolol. The patient was diagnosed as pityriasis rosea-like adverse reaction to atenolol based on her history, dermatological examination and histopathological findings. To the best of our knowledge, this is the first reported case of pityriasis rosea-like adverse reaction to atenolol that is widely used in hypertension treatment.

West Nile Virus Infection in Horses: Detection by Immunohistochemistry, In Situ Hybridization, and ELISA

This study describes the clinicopathologic findings in naturally occurring West Nile virus (WNV) infection in horses. WNV was diagnosed in a foal by immunohistochemical and in situ hybridization methods, and the presence of WNV antibodies was detected in 5 other horses with clinical signs suggestive of WNV infection. At necropsy of the foal, lymph nodes were edematous and enlarged, and the intestines showed diffuse congestion and focal hemorrhages. The most significant histologic lesions in this case were nonsuppurative meningoencephalomyelitis, particularly in the brainstem and spinal cord. Identification of viral RNA by in situ hybridization and viral antigen by immunohistochemistry was concentrated primarily in nerve fibers, glial cells, and their processes in brainstem and spinal cord and, to a lesser extent, within the cerebral hemispheres and cerebellum.

Amitriptyline overdose in emergency department of university hospital: evaluation of 250 patients

OBJECTIVE

The purpose of this study was to evaluate the patients with acute amitriptyline poisoning and investigate predictive factors for the development of life-threatening complications.

METHODS

Demographics, clinical, laboratory, and electrocardiographic (ECG) findings of 250 patients were evaluated retrospectively. Predictive parameters for the development of serious complications were studied.

RESULTS

Median age of patients was 14.6 years, of which, 70% of patients were female and 66% were in pediatric age group. The most common pathological clinical finding and laboratory abnormality were alteration of consciousness and hyponatremia. The rate of convulsive seizure, arrhythmia, and respiratory depression were 17 (6.8%), 16 (6.4%), and 11 (4.4%), respectively. These complications were more seen in pediatric patients than adults (15.8% and 1.2%). The incidence of hyponatremia was more in pediatric patients and severe poisoning groups (38.8 and 53.4%, respectively). The levels of amitriptyline and nortriptyline were significantly higher in the group with complications than the group without complications (p < 0.05). All adult patients were discharged with good prognosis. In pediatric age group, one patient was discharged with severe neurological sequelae and one patient died. QRS duration >100 ms, long corrected QT duration interval, and low Glasgow Coma Score (GCS) at admission were identified as independent risk factors for the development of life-threatening complications (odds ratio: 69.4, 1.9, and 1383, respectively; p < 0.05).

CONCLUSION

Amitriptyline poisoning may be associated with life-threatening complications, especially in pediatric age group and in patients with hyponatremia. Low GCS, presence of hyponatremia, high serum drug levels, and pathological ECG findings on admission may be helpful in predicting the development of complications and poor prognosis.

Sarcomatoid renal cell carcinoma with scant epithelial components in an Angora cat

CASE HISTORY

A 6-year-old, neutered, female Angora cat presented with a history of lethargy and anorexia for 2 months and a clinically palpable and gradually enlarging, solid mass in the abdominal cavity extending from the last costal arch to the pelvic cavity.

CLINICAL FINDINGS

Examination of the cat revealed jaundice, dehydration and hypothermia. Haematological manifestations included lymphopenia and substantial decrease in haematocrit value. Biochemical analysis of the blood revealed hypoglycaemia, three-fold elevated blood urea nitrogen values, increased level of serum aspartate aminotransferase and increased total bilirubin while the creatinine level was normal. Ultrasonographic examination of the abdomen showed a disrupted and large hypoechoic area around the left kidney. The cat was anaesthetised and the left kidney was removed, but the cat died following surgery.

PATHOLOGICAL FINDINGS

On post-mortem examination, the left kidney was markedly enlarged and both the cortical and medullary parenchyma were replaced by confluent, multilobulated, pale tan-white, firm nodular masses protruding above the capsular surface. Metastasis was not observed. Cytological examination revealed a population of spindle-shaped cells of variable size, with abundant coarse chromatin and occasionally prominent nucleoli. Initial sections of the kidney were indicative of undifferentiated sarcoma confirmed by immunohistochemistry revealing vimentin-positive and cytokeratin-negative results in all tumour tissues. Additional sections showed very small amounts of both cytokeratin-positive and vimentin-positive areas.

DIAGNOSIS

Sarcomatoid renal cell carcinoma (SRCC) with scant epithelial components originating from left kidney.

CLINICAL RELEVANCE

Clinical and pathological features were similar to those of human SRCC, even though there was no evidence of metastases. Immunohistochemistry for vimentin and cytokeratin may be useful for definitive diagnosis of renal cell carcinoma with sarcomatoid differentiation, although staining of sections from several different parts of the tumour may be necessary. When a primary renal tumour is presented, SRCC should be considered as this diagnosis may influence treatment protocols and the clinical outcome.

Bullous skin reaction seen after extravasation of calcium gluconate

Intravenous (IV) calcium is usually given to temporarily treat the effects of hyperkalaemia on muscle and heart. When extravasation of a calcium gluconate infusion occurs, there may be rapid and marked swelling and erythema, with signs of soft-tissue necrosis or infection, and ensuing extensive local calcification, called calcinosis cutis. We report a 26-year-old woman who was hospitalized for exacerbation of acute intermittent porphyria. She had a history of hypertension and chronic renal failure. On the second day of her hospitalization, she developed hyperpotassaemia (6.7 mEq/L potassium; normal range 3.5-5 mEq/L). She was given an IV infusion of 10 mL calcium gluconate into the left dorsal pedal vein. Bullous skin reactions occurred in the infusion area nearly 2 h after administration. The patient's leg was elevated and the lesions cleaned with 0.9% saline. By day 9 of hospitalization, the lesions had markedly regressed. Several drugs have been associated with dermoepidermal blistering as an adverse drug reaction, but there is only one existing report in the literature about this side-effect associated with calcium gluconate. Clinicians should be alert to the possibility of bullous skin reactions, which may be a predictor of extravasation and necrosis, when treating patients with IV calcium gluconate.

Occurrence of ovine herpesvirus type-2 infection in sheep and cattle in Samsun Province, Turkey

July 2004, a cow with clinical signs of ovine herpesvirus type-2 infection which is known as sheep associated malignant catarrhal fever (SA-MCF) was reported in Samsun Province in Turkey. Blood samples were collected from the suspected cow, 10 sheep housed with it, and from 150 healthy sheep and 29 healthy cattle randomly selected from different places in Samsun Province. Nested polymerase chain reaction (n-PCR) was used to detect ovine herpesvirus type-2 (OvHV-2) DNA in the suspected cow and competitive- ELISA (c-ELISA) kits were used to detect antibodies against OvHV-2. The suspected cow was found to be n-PCR positive and c-ELISA negative. The serological results were as follows: All 10 (100%) of sheep housed with the suspected cow and 18 of 29 (62%) of the randomly selected cattle were found seropositive. All 150 randomly selected healthy sheep were seronegative. The overall percentage of seropositivity was 14.7% (28/190). OvHV-2 DNA was detected in the peripheral blood leucocyte (PBL) samples of the cow and of the 10 sheep housed with the suspected cow.
