Objective: To investigate the presence, prevalence and phylogenetic classification of bovine torovirus (BToV). Methods: Stool samples from 72 calves, which were negative for primary gastroenteritis agents, were examined with the nested PCR method by using BToV M gene-specific primers. Results: BToV was detected in 12 (16.7%) out of 72 samples. Phylogenetic analysis was performed using nucleotide and amino acid sequences. In the phylogenetic tree, European, American, Far East and Turkish strains were found to be divided into different branches. Interestingly, it was observed that Turkish strains were divided into two subgroups. Considering the amino acid sequences of these strains having differences at nucleotide level, the change at the 3rd amino acid of the partial M gene in Turkish strains has made Turkish strains different from all other strains. Similarly, the differences were observed in the 18th, 20th, 63rd and 93rd amino acids of the partial M gene only in Turkish field strains. Conclusions: This study revealed that Turkish strains of BToV constitute a separate phylogenetic group and can be divided into two subgroups. In addition, BToV was found to be a common pathogen causing diarrhea in calves in Turkey, and it is a necessity to consider BToV in cases of diarrhea with unknown cause.

A Collagenous Fibroma (Desmoplastic Fibroblastoma) is a rare, benign, slowly growing, fibroblastic, soft tissue lesion. Here, the case of a 28-year-old woman, who presented with a 1-year history of a slowly growing painless mass in the right anterior aspect of her neck, is described. This type of tumor was first described by Evans in 1995, and named as a Desmoplastic fibroblastoma but was renamed, by Nielsen in 1996 as a Collagenous Fibroma. This type of tumor is frequently reported in men with a mean age at occurance of 50 years. Clinically, a Collagenous fibroma presents as a firm, well-circumscribed subcutaneous, or intramuscular, painless mass of long duration. They are mostly located in the neck and extremities. The tumors range in size from 1 to 20 cm and predominantly occurs within the subcutaneous tissue, but fascial and skeletal muscle involvement is common. The treatment of a Collagenous Fibroma is a total surgical excision. No tumor recurrence has been reported the literature during the follow-up period and no tumor recurrence was observed in our case at the 1-year follow-up.

PURPOSE: Pelvic organ prolapse is a multifactorial disorder in which extracellular matrix defects are implicated. Fibrillin-1 level is reduced in stress urinary incontinence. In Marfan syndrome, which is associated with mutations in Fibrillin-1, pelvic floor disorders are commonly observed. We hypothesize that Fibrillin-1 gene expression is altered in pelvic organ prolapse. METHODS: Thirty women undergoing colporrhaphy or hysterectomy because of cystocele, rectocele, cystorectocele, or uterine prolapse were assigned to a pelvic prolapse study group, and thirty women undergone hysterectomy for nonpelvic prolapse conditions were assigned to a control group. Real-time polymerase chain reaction was conducted on vaginal tissue samples to measure the expression of Fibrillin-1. Expression levels were compared between study and control groups by Mann-Whitney U test with Bonferroni revision. RESULTS: Fibrillin-1 gene expression was not significantly lower in the study group than in the control group. Similarly, no significant correlation between Fibrillin-1 levels and grade of pelvic prolapse was found. Age over 40 years (P=0.018) and menopause (P=0.027) were both associated with reduced Fibrillin-1 levels in the pelvic prolapse group, whereas the delivery of babies weighing over 3,500 g at birth was associated with increased Fibrillin-1 expression (P=0.006). CONCLUSIONS: The results did not indicate a significant reduction in Fibrillin-1 gene expression in pelvic prolapse disorders; however, reduced Fibrillin-1 may contribute to increased pelvic organ prolapse risk with age and menopause. Increased Fibrillin-1 gene expression may be a compensatory mechanism in cases of delivery of babies with high birth weight. Further studies are needed for a better understanding of these observations.
