RESUMO

OBJECTIVES: To determine the safety of urological admissions and procedures during the height of the COVID-19 pandemic using "hot" and "cold" sites. The secondary objective is to determine risk factors of contracting COVID-19 within our cohort. PATIENTS AND METHODS: A retrospective cohort study of all consecutive patients admitted from March 1 to May 31, 2020 at a high-volume tertiary urology department in London, United Kingdom. Elective surgery was carried out at a "cold" site requiring a negative COVID-19 swab 72-hours prior to admission and patients were required to self-isolate for 14-days preoperatively, while all acute admissions were admitted to the "hot" site.Complications related to COVID-19 were presented as percentages. Risk factors for developing COVID-19 infection were determined using multivariate logistic regression analysis. RESULTS: A total of 611 patients, 451 (73.8%) male and 160 (26.2%) female, with a median age of 57 (interquartile range 44-70) were admitted under the urology team; 101 (16.5%) on the "cold" site and 510 (83.5%) on the "hot" site. Procedures were performed in 495 patients of which eight (1.6%) contracted COVID-19 postoperatively with one (0.2%) postoperative mortality due to COVID-19. Overall, COVID-19 was detected in 20 (3.3%) patients with two (0.3%) deaths. Length of stay was associated with contracting COVID-19 in our cohort (OR 1.25, 95% CI 1.13-1.39). CONCLUSIONS: Continuation of urological procedures using "hot" and "cold" sites throughout the COVID-19 pandemic was safe practice, although the risk of COVID-19 remained and is underlined by a postoperative mortality.

RESUMO

This study investigates the occurrence of erythematous lip lesions in a captive sun bear population in Cambodia, including the progression of cheilitis to squamous cell carcinoma, and the presence of Ursid gammaherpesvirus 1. Visual assessment conducted in 2015 and 2016 recorded the prevalence and severity of lesions. Opportunistic sampling for disease testing was conducted on a subset of 39 sun bears, with histopathological examination of lip and tongue biopsies and PCR testing of oral swabs and tissue biopsies collected during health examinations. Lip lesions were similarly prevalent in 2015 (66.0%) and 2016 (68.3%). Degradation of lip lesion severity was seen between 2015 and 2016, and the odds of having lip lesions, having more severe lip lesions, and having lip lesion degradation over time, all increased with age. Cheilitis was found in all lip lesion biopsies, with histological confirmation of squamous cell carcinoma in 64.5% of cases. Single biopsies frequently showed progression from dysplasia to neoplasia. Eighteen of 31 sun bears (58.1%) had at least one sample positive for Ursid gammaherpesvirus 1. The virus was detected in sun bears with and without lip lesions, however due to case selection being strongly biased towards those showing lip lesions it was not possible to test for association between Ursid gammaherpesvirus 1 and lip squamous cell carcinoma. Given gammaherpesviruses can play a role in cancer development under certain conditions in other species, we believe further investigation into Ursid gammaherpesvirus 1 as one of a number of possible co-factors in the progression of lip lesions to squamous cell carcinoma is warranted. This study highlights the progressively neoplastic nature of this lip lesion syndrome in sun bears which has consequences for captive and re-release management. Similarly, the detection of Ursid gammaherpesvirus 1 should be considered in pre-release risk analyses, at least until data is available on the prevalence of the virus in wild sun bears.

RESUMO

Bats are known reservoirs of a wide variety of viruses that rarely result in overt clinical disease in the bat host. However, anthropogenic influences on the landscape and climate can change species assemblages and interactions, as well as undermine host-resilience. The cumulative result is a disturbance of bat-pathogen dynamics, which facilitate spillover events to sympatric species, and may threaten bat communities already facing synergistic stressors through ecological change. Therefore, characterisation of viral pathogens in bat communities provides important basal information to monitor and predict the emergence of diseases relevant to conservation and public health. This study used targeted molecular techniques, serological assays and next generation sequencing to characterise adenoviruses, coronaviruses and paramyxoviruses from 11 species of insectivorous bats within the South West Botanical Province of Western Australia. Phylogenetic analysis indicated complex ecological interactions including virus-host associations, cross-species infections, and multiple viral strains circulating concurrently within selected bat populations. Additionally, we describe the entire coding sequences for five alphacoronaviruses (representing four putative new species), and one novel adenovirus. Results indicate that viral burden (both prevalence and richness) is not homogeneous among species, with Chalinolobus gouldii identified as a key epidemiological element within the studied communities.

RESUMO

During a study on health and disease in Red-crowned Parakeets (Cyanoramphus novaezelandiae) on Tiritiri Matangi Island and Little Barrier Island (Hauturu-o-Toi) in New Zealand between 2011 and 2013, an outbreak of feather loss prompted the collection of skin biopsies (n = 135) under anesthesia from the head of captured birds. A subset of samples (n = 7) was frozen to obtain whole specimens for identification of ectoparasites. Mites (range 1-11) were observed in 79/135 (58.5%) skin biopsies, whereas feather loss was only found in 47/142 (33.1%) birds captured during the sampling period. Compact orthokeratotic hyperkeratosis and acanthosis were found in association with mites. Procnemidocoptes janssensi (Acari: Epidermoptidae, Knemidokoptinae) was identified from whole mites obtained from skin biopsies. We describe the presence, pathology, and stages of infestation for knemidokoptinid mange in a wild parrot population in New Zealand. Given the clinical and pathologic changes observed and poor knowledge of the parasite's New Zealand host and geographic distribution, further work is recommended for this and sympatric parrots, to understand relationships between the host, parasite, environment, and expression of disease. Results from this study reinforce the value of including biopsy samples for the investigation of skin disease in wild birds, particularly to link etiologic agents with pathologic changes.

RESUMO

Granular cell tumors are uncommon, usually benign tumors of neural origin. They are most often diagnosed in the third to sixth decades of life and are infrequently seen in the pediatric population. Although they can be found in a wide distribution throughout the body, more than half occur in the oral cavity and other head and neck sites such as the larynx. We report a granular cell tumor on the distal toe of a 5-year-old child, removed with Mohs surgery. Review of the English language literature revealed four previously reported granular cell tumors treated with Mohs micrographic surgery, none of which was in a child.

RESUMO

OBJECTIVE: To review the presentation of endometriosis, steps to diagnosis, and medical and surgical management options. SOURCES OF INFORMATION: MEDLINE was searched from January 1996 to November 2004, EMBASE from January 1996 to January 2005, and the Cochrane Database of Systematic Reviews for the 4th quarter of 2004. MAIN MESSAGE: Endometriosis is a common, progressive disease with an estimated prevalence of 10%. It can cause dyspareunia, dysmenorrhea, low back pain, and infertility. It can be diagnosed on clinical grounds and treated without laparoscopy provided pregnancy is not desired. First- and second-line medical treatments are nonsteroidal anti-inflammatory drugs, combined oral contraceptive pills, progestins, gonadotropin-releasing hormone agonists, and androgens. Surgical options should be considered when these medications are ineffective or if pregnancy is desired. CONCLUSION: Family physicians have an important role in diagnosing and treating women with endometriosis.

RESUMO

OBJECTIVE: To present a practical approach to the symptom complex called chronic pelvic pain (CPP). Chronic pelvic pain is defined as nonmenstrual pain lasting 6 months or more that is severe enough to cause functional disability or require medical or surgical treatment. SOURCES OF INFORMATION: MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews were searched from January 1996 to December 2004. MAIN MESSAGE: While the source of pain in CPP can be gynecologic, urologic, gastrointestinal, musculoskeletal, or psychoneurologic, 4 conditions account for most CPP: endometriosis, adhesions, interstitial cystitis, and irritable bowel syndrome. More than one source of pain can be found in the same patient. Management involves treating the underlying condition, the pain itself, or both. Nonnarcotic analgesics are first-line therapy for pain relief; hormonal therapies are beneficial if the pain has a cyclical component. A multidisciplinary approach addressing environmental factors and incorporating medical management with physiotherapy, psychotherapy, and dietary modifications works best. CONCLUSION: Although caring for patients with CPP can be challenging and frustrating, family physicians are in an ideal position to manage and coordinate their care.
