Publisher: 2013Dissertation note: Prolene (Polypropylene) is a gold standard for repairing ventral or incisional hernias but exhibits increased inflammatory responses as a non-absorbable foreign material and causing post-operative complications. Prolene composite mesh has a reduced polypropylene concentration in addition to an equal proportion of absorbable material. Hence they provide more tissue in-growth and less inflammatory response and minimal adhesion formation.
The present project was designed to compare the two mesh implants viz., the simple non-absorbable poly-propylene (prolene) mesh and the prolene-vicryl composite mesh which is comprised of an outer latticework of the non-absorbable polypropylene, in addition to absorbable polyglactin 910 (vicryl) on the inner side. Both mesh implants are readily available in Pakistan; the non-absorbable polypropylene mesh is available in Pakistan with the Trade name of Prolene® (Ethicon, Johnson & Johnson, USA), while the prolene-vicryl composite mesh is available with the Trade name of Vypro® (Ethicon, Johnson & Johnson, USA). Both meshes were compared on the basis of post-surgical complications (Pain evaluation, wound healing, hematoma, seroma and abscess formation), inflammatory responses mesh shrinkage and adhesion formation after application of hernioplasty implant.
The experimental study was conducted on 12 (twelve) healthy mongrel dogs to compare prolene and prolene-vicryl composite mesh for ventral or incisional hernia repair in dogs. The dogs were randomly selected as either male or female, aged between one to two years (mean age 1.5 years). The body weight of the experimental animals was in the range between 16-20 kg (mean weight 18 kg). The dogs were housed in kennels at Pet Centre of University of Veterinary and Animal Sciences, Lahore for a period of 3 months (including adaptation and post-operative period). The dogs were divided into three groups (A, B & C) comprising of 4 dogs in each group; and they were numbered from # 1-4 in Group A, #5-8 dogs in Group B, and #9-12 dogs in Group C, for proper identification and for ease of research. The respective meshes were used for ventral or incisional hernia repair in group A and group B dogs, while group C dogs served as control group.
The groups were surgically treated as follows:
Group A (Prolene mesh)
Group B (Prolene-vicryl composite mesh)
Group C (Control group)
During experimental trials, it was seen that polypropylene mesh resulted in a persistent inflammatory response, prominent foreign body reaction, rare vascularization, more fibroblast more granulating tissue, increased thickness of connective tissue, and extensive collagen fiber. In comparison, the polypropylene-vicryl composite mesh resulted in better vascularization, rare inflammatory response, moderate collagen fiber formation, smooth incorporation of collagen fibers into the mesh, low foreign body reaction, less fibroblast proliferation and lesser granulating tissue.
Based upon all the findings it was concluded that the Prolene-Vicryl composite mesh is safer and more effective in terms of post-operative complications and outcomes.

Publisher: 2015Dissertation note: Diagnostic ultrasound was introduced as diagnostic modality in equines in 1982 by Rantanen. Horses are widely used across Pakistan for polo, race and draught purpose. Tendinopathies along with associated arthropathies and / or soft tissue trauma are common aliments among feet problems. However, no work has been done so far in Pakistan regarding the precise sonographic diagnosis of these problems and the seat of lameness, which results in the early culling of these horses. Advancements in diagnostic imaging have greatly improved the efficiency of the veterinarians in diagnosing soft tissues abnormalities. The present project was aimed to addressed these issues regarding precise lameness diagnosis in equines, with respect to sonographic presentation of the tendons, soft tissues and associated joints, and hence, to initiate precise diagnosis for effective treatment in future.
The study was designed to precisely diagnose and characterize the soft tissue injuries occurring concurrently with joint involvement, in the three predominant categories of horses in and around Lahore, viz., Race, Polo and draught-purpose.
For this purpose, twenty-four horses were divided into three groups i.e. A, B and C, each group comprising eight horses. Furthermore, each group were subdivided into two subgroups with four clinically sound horses and four unsound horses presented with soft tissues abnormalities occurring concurrently with or without joint involvement. The changes between sound and unsound structures were compared through intra-group and inter-group comparison.
The study was aimed towards practical needs in addressing to the precise sonographic diagnosis for the seat of lameness and characterization of the lesion. Conclusively, percentage

occurrence and degree of prognosis were assessed. Besides, it will futuristically augment in proper treatment of our precious animals.
Different soft tissue structures of various joints (elbow, carpus, MCP/MCT, stifle, and hock) were sonographically imaged both in sound and unsound horses for the percentage occurences of injuries in all the three group, along with degree of lameness, degree of pain, degree of range of motion in each joint and degree of prognosis. The parameters shown significant correlation with minor differences.
The study proved that occurrence of tendinopathies and associated joint trauma are more common in race horses than in polo and draught-purpose horses. The data regarding sonography of the joints was analyzed by using chi square test with the help of SPSS version 17.
The study can be used as a proven tool for the early diagnosis, prognosis of soft tissue abnormalities and facilitate both veterinarians and owners in long run and can also be used for treatment purposes.Diagnostic ultrasound was introduced as diagnostic modality in equines in 1982 by Rantanen.
