Nonsurgical fertility control is increasingly advocated as more cost-effective than surgical sterilization to manage stray animal populations in a different part of the world. An experimental study was conducted from December 2018 to April 2019 at Mekelle University to evaluate the effect of single bilateral intratesticular injection of cetrimide 2% in adult albino mice. A total of 20 clinically healthy albino mice selected based on their age and sex and were divided randomly into five groups and evaluation was conducted for 30 days after intratesticular injection of cetrimide solution 2% at the dose rate of 5, 10, 15 and 20 mg per testis and for control 0.1 mL normal saline per testis per 100 g body weight were given. All albino mice were evaluated for 30 days at a fixed interval. Change in body weight, scrotal width, sexual behavior, and fertility performance was also assessed. On day 30, all albino mice were sacrificed for histopathological study. Means  ±  Standard deviation of the mean, one-way, and a mixed model ANOVA (for repeated measures) was used to summarize the data, determine the effects of group and time on bodyweight and scrotal width. The significant increase in body weight (p - 0.001) and significant reduction of scrotal width (p - 0.001) were noted in all cetrimide treated in comparison to control groups. In addition, there was a significant (p < 0.05) reduction of scrotal width in albino mice after intratesticular injection of cetrimide on day 1, 10, 15, 20, 25, and 30 with respect to their experimental groups. Testicular histology revealed that there were multinucleated giant cells in seminiferous tubules, derangement of tubular architecture along with infiltration of leucocytes and appearance of fibrous tissue were seen on testicular sections at a dose rate of 15 and 20 mg. Similarly, a significant change in the sexual behavior of the treated males and no pregnancy was detected on female albino mice after 21 days post-coital at 10, 15, or 20 mg cetrimide-treated males. In conclusion, a single bilateral intratesticular injection of cetrimide 2% at a dose of 15 and 20 mg might provide an effective way of sterilization and may be considered as an alternative to surgical castration in male animals. Besides, further assessment should be done in the future to identify the mechanism of infertility.

Oral Candida colonization in HIV-infected patients: Species and antifungal susceptibility in Tripoli/Libya

Published on: 3rd August, 2018

OCLC Number/Unique Identifier: 7844539006

Introduction: Candidiasis is more frequent in human immunodeficiency virus (HIV)-infected patients and knowledge about the distribution and antifungal susceptibility of oral Candida species is important for effective management of candidiasis. Material and Methods: An oral rinses sample collected from hundred HIV-infected patients with and without clinical evidence of oral candidiasis in this study at the Infectious Department/Tripoli Medical Center, Libya. Species identified by standard phenotypic and conventional methods and in vitro susceptibility testing of the yeast isolates to antifungals were performed using the Disc diffusion method protocol as recommended by the Clinical Laboratory Scientific Institute. Results: Oral Candida colonization is detected in all patients with and without clinical syndromes, and Candida albicans were accounted for (74%), C. dubliniensis (11%) and C. glabrata (6%). A high proportion of Candida species (42%) showed decreased susceptibility to fluconazole. Among C., albicans more than 30% of isolate were resistant to most new azole antifungal including fluconazole, itraconazole, posoconazole and voriconazole. Conclusions: A significant number of oral Candida species particular Candida albicans exhibiting decreased susceptibility to fluconazole were isolated from colonized HIV-infected individual, given the high incidence and severity of fungal infections in HIV-infected individuals. The results of this study reinforce the importance of antifungal susceptibility testing, which contributes to the therapeutic strategies and highlights the need for continuous surveillance of Candida colonization in this population.

Review on impacts of COVID-19 pandemic on life animals and dairy product processing industries of the world

Published on: 22nd May, 2020

OCLC Number/Unique Identifier: 8617040327

This review was conducted for the objective of assessing causes of COVID-19 pandemic impacts on life animals and dairy product processing industry of the world. Since its outbreak in Wuhan town of China, the newly emerged strains of corona virus COVID-19 causes incredible crisis both on life animal and its product especially dairy industry of the globe. During the outbreak of the virus, majority of the world people were stayed home to prevent the spread of the diseases. At that time, the wildlife found in the zoo were exposed to diseases and missed human attention, global wildlife trade was spotlighted and wildlife was running… wild. For the reason of COVID-19 pandemic, many schools and restaurants which received dairy product from dairy producers and cooperatives were shutdown. Due to schools and restaurant shutter, milk supply chain was disrupted. For this moment milk demand and supply was decreased, huge volume of milk was dumped, mode of milk trade was changed, market and farm prices was fluctuated, import- export route was interrupted and Farm workforce absenteeism were some of the challenges cases dairy industry crisis. Trade law modification, provision of financial assistance for dairy industry and farmers, and expansion of export route were the measures taken by concerned bodies to save dairy industry from corona virus crisis. Therefore, COVID-19 pandemic is the disaster diseases which causes social and economic crisis on dairy producers of the world. So, to save wildlife and dairy industry from corona virus crisis, global solidarity prevention is mandatory.

In vitro antimicrobial activity of a black currant oil based shampoo versus a chlorhexidine 4% shampoo on bacteria strains isolated from canine pyoderma: A comparative study

Published on: 14th April, 2020

OCLC Number/Unique Identifier: 8875582641

Over the last few years, antimicrobial shampoo therapy has been increasingly used to treat skin infections in order to reduce systemic use of antibiotics. This study was aimed to compare the In vitro bactericidal effect of a black currant oil based shampoo (S1) to a chlorhexidine 4% shampoo (S2) against methicillin-sensitive Staphylococcus pseudintermedius (MSSP), methicillin-resistant Staphylococcus pseudintermedius (MRSP), Staphylococcus aureus (SA), Escherichia coli (EC) and Pseudomonas aeruginosa (PA) isolates. A collection of 50 bacterial strains from skin swabs of dogs with superficial recurrent pyoderma was selected: 10 MSSP, 10 MRSP, 10 SA, 10 EC and 10 PA. The two shampoos were blindly tested in duplicate with a microdilution plate method, with scalar concentrations from 1:2 to 1: 256. The MBC was performed for each dilution. A linear regression was used to detect a statistically significance between the two shampoos. All isolates were completely killed at 1:2 up to 1:16 dilution of the two antiseptic products. At the 1:32 dilution the first bacterial growths were observed, in particular for 2 and 4 strains of MRSP by S1 and S2 respectively. The first lethal dilution for SA was at 1:64 for S1/S2 and only for S2 against SP. No significant difference was observed between the two shampoos according to the results of linear regression significant for: i) MRSP, PA and EC (p < 0.05); ii) MSSP and SA (p < 0.1). This study showed that both black currant oil based shampoo and chlorhexidine 4% shampoo have a similar In vitro bactericidal activity.

Dairy cattle producers’ perception on Oestrus Synchronization and mass artificial insemination services in Waliso and Ilu Districts of South West Shoa Zone of Oromia, Ethiopia

Published on: 5th March, 2020

OCLC Number/Unique Identifier: 8545201990

The study was conducted in Ilu and Waliso districs of South West Shoa Zone to investigate the perception of dairy cattle producers on oestrus synchronization and mass artificial insemination services. A total of 122 respondents (38 from Ilu and 84 from Waliso districts) owning at least one lactating cow and participated in synchronization program were randomly selected and interviewed individually by using semi- structured questionnaire. Both primary and secondary data were used to generate reliable information on the intended topic. All collected data were analyzed using SPSS statistical package version 20 and the output was presented by descriptive statistics such as percentage and mean values in inform of graphs. Most of the respondents (67.15%) indicated that their satisfaction level towards synchronization and mass artificial insemination was low. Only few of them reported being satisfied as (medium-13.45%, good - 12.35% and very good - 7.05%). This might be because of shortage of feed, silent heat, poor performance of the inseminator and low awareness of farmers on the technology. From the study it was also noted that the overall percentage (26.22%) of calving rate to oestrus synchronization and mass artificial insemination was low. This might be due to heat detection problem (36%); A.I technician efficiency (29.25%), absence of A.I technician (23.9%) and distance of A.I center (10.25%). Therefore, the skill and knowledge based training should be given for both the farmers and implementers to enhance perception and adoption of the technology.

Premaxillary osteotomy in children with bilateral cleft lip and palate: Skeletal and dental changes

Published on: 16th July, 2020

OCLC Number/Unique Identifier: 8639114756

Purpose: To evaluate changes in children with bilateral cleft lip and palate (BCLP) who premaxillary osteotomy and secondary alveolar bone grafting as compared to children with BCLP who are not indicated for surgery, and to determine variables that differentiate patients who do or do not require osteotomy. Material and methods: Twenty-four children with BCLP were included in the study: 12 who underwent osteotomy (intervention group) and 12 who had no surgery (control group). Radiographic and model values of the intervention group were compared before (T1) and after (T2) premaxillary osteotomy, and measurements were compared with those from the control group at T1. Results: Convexity, ANB (point A-nasion-point B), and maxillary depth was more diminished at T2 in children in the intervention group. Point A, anterior nasal spine, and pogonion were retroposed after surgery, and the anterior spine was higher. At T2, the upper incisors were proinclinated and intruded, and overbite was improved. Models revealed increased intermolar intercanine width as well as intrusion of upper incisor after surgery. Premaxilla and upper molars were more extruded, had a higher total maxillary height and increased extrusion of upper incisor in children who underwent osteotomy. Conclusion: After surgery, children who undergo surgery have a premaxilla that is more normalized and more level with the occlusal plane, as well as improved dental inclination. Variables that differentiate children who require osteotomy from those who do not include more extrusion and protrusion of the premaxilla, and a greater extrusion of the upper incisors.

Twin-stage technique for occlusal rehabilitation of a mutilated dentition – A case report

Published on: 28th May, 2020

OCLC Number/Unique Identifier: 8627834705

Functional and aesthetic rehabilitation of an extremely worn dentition is one of the most challenging aspects of Prosthodontics. A thorough examination and diagnosis & selection of appropriate occlusal scheme are key factors to achieve optimal clinical outcome. Among the variety of techniques suggested in the literature, the twin-stage technique given by Hobo & Takayama has emerged as a popular choice for clinicians in recent times. Instead of the condylar path, it utilizes standard cuspal angle as the main determinant of articulation to produce predictable disocclusion in eccentric movements. It is relatively simple, does not require special armamentarium and can be incorporated easily with commonly used clinical techniques such as face bow transfer. The present case report describes the full mouth rehabilitation of a severely mutilated dentition using Hobo’s twin-stage technique to achieve a functionally and aesthetically favourable outcome.

Management of temporomandibudar joint ankylosis with costo-chondral graft application: Case report and review of literature

Published on: 27th February, 2020

OCLC Number/Unique Identifier: 8560390804

Introduction: Temporomandibular joint (TMJ) ankylosis is one of the most disruptive anomaly that affects the masticatory system and is referred as permanent movement disfunction of the mandible caused by bilateral or unilateral fibrous or bony adhesions and create problems. The etiology is congenital or idiopathic and include trauma, arthritis, infection, previous TMJ surgery etc. Management requires extensive resection of the ankylotic mass and reconstruction of the ramus-condyle unit with autogenous or alloplastic grafts. Most of the time, combination of surgical treatment with physiotherapy is needed in order to achieve maximum rehabilitation and functionality of the mandible. Purpose: The aim of this study is to present the surgical management of an unusual case of unilateral TMJ ankylosis and recent of literature review. Case report: A thirty-seven-year old patient reported unable moving his lower jaw. Clinical examination revealed unilateral TMJ ankylosis of congenital cause and the lateral movement of the mandible was impossible. The patient surgical treatment included resection of the newly formed bone mass, replacement of the condyle with costo-chondral graft and replaced of articular disc with the temporal fascia. Since and for ten years after surgery the patient shows no signs of relapse. Conclusion: The development of TMJ ankylosis may be congenital or acquired etiology. In order to manage it required a comprehensive clinical and radiographic examination. Surgical resection of the bone and coronoid process on the entire side is necessary and a graft that mimics the articular disc is placed, while it is necessary the immediate postoperative kinesiotherapy.
