Introduction: Breast cancer is the most common cancer of women in the world. Twenty-five percent of people living with the human immunodeficiency virus (HIV) reside in South Africa. The coincidence of breast cancer and HIV infection is therefore common in South Africa. There is a perception that systemic and local surgical complications are more common in HIV-infected patients, and that these patients tolerate chemo- and radiotherapy poorly., Aim: The aim of the study was to determine the effect of HIV infection on the management of breast cancer by comparing HIV-infected to -noninfected patients. The outcomes of surgery and adjuvant/neoadjuvant therapy were examined in these groups., Method: The study was performed at the Steve Biko Academic Hospital, Pretoria, South Africa, during 2009-2014. Patients scheduled for surgery for breast cancer were recruited prospectively and their HIV status was determined. All patients were managed according to standard guidelines for breast cancer. Patients were followed up for 30 days and local and systemic surgical complications documented. Completion or non-completion of courses of chemo- and radiotherapy, and reasons for non-completion were documented. HIV-infected and -noninfected patients respectively were grouped, and compared statistically., Results: One hundred and sixty patients (31 HIV-infected) were included. The frequency of surgical complications did not differ significantly between HIV-noninfected and infected patients (p = 0.08), more occurring in the HIV-noninfected patients. The risk ratio of HIV infection for surgical complications was 0.20 and the odds ratio 0.23. The completion of courses of chemo- and radiotherapy did not differ between the HIV-infected and -noninfected patients. Twenty-five of 27 HIV-infected patients (93%) and 100 of 113 HIV-noninfected patients (94%) completed their courses of chemotherapy (p = 0.68). Twelve of 14 HIV-infected patients (86%) and 40 of 41 HIV-noninfected patients (98%) completed their courses of radiotherapy (p = 0.16)., Conclusion: These results suggest that HIV-infected patients with breast cancer do not experience more treatment-related complications and can be treated according to standard guidelines., (Copyright © 2016 IJS Publishing Group Ltd.

Dental care is an integral part of equine veterinary practice. The objectives of this cross sectional study were to describe the prevalence of dental disorders in an abattoir population of horses, and to compare oral examination of intact and bisected heads. Heads from 40 horses, 19 males and 21 females, were examined and divided into immature, adult or older horses based on dental age. Older horses had a significantly higher prevalence of infundibular caries (91.7%), diastemata (66.7%) and fractures (58.3%), whereas dental wear disorders affected all age groups. Gasterophilus spp. larvae were detected in 20% of the horses. A short oral examination performed on intact heads was adequate for diagnosing major disorders, but the occurrence of many conditions had only fair to poor agreement with the bisected heads. A more detailed oral examination may be needed for reliable diagnosis of many disorders., (Copyright © 2015 Elsevier Ltd. All rights reserved.)

Background: Resectional breast surgery has become less extensive. Dissection on plane of the superficial fascia covering the breast (juxtacapsular) is used during various procedures for retention of the appearance of the breast. The accuracy of this method and its ability to remove all glandular breast tissue has never been tested., Methods: Twenty patients with breast cancer were studied prospectively. Juxtacapsular dissection of the inferior flap was performed during mastectomy. Biopsies were taken on each side of the dissection plane at 3 sites: median, medial and lateral. Several histological slides were prepared from each biopsy and examined for the presence of breast parenchymal or dispersed glandular tissue., Results: Three hundred and forty nine histological slides were examined, 185 from the resected breast side and 164 from the subcutaneous side. Ninety four percent of the slides from the breast side contained glandular tissue. Breast glandular tissue was found outside the dissection plane in 16 of 20 cases and in 33% of slides. This was sparse and dispersed in 69% of slides. A mean of 81% of slides from individual cases revealed glandular tissue inside and the absence of glandular tissue outside the dissection plane ("expected result"), demonstrating predominantly accurate juxtacapsular dissection., Conclusion: This study demonstrated that accurate juxtacapsular inferior flap dissection leaves behind glandular breast tissue in a greater proportion of cases than any previous study. While this tissue is sparsely-distributed, surgeons should be aware of the occurrence of glandular breast tissue outside the juxtacapsular dissection plane in the majority of cases., (Copyright © 2014 Surgical Associates Ltd.
