Acceptance and perception of Nigerian patients to medical photography.

The aim of the study was to determine the acceptance and perception of Nigerian patients to medical photography. A self-administered questionnaire was distributed among Nigerian patients attending oral and maxillofacial surgery and plastic surgery clinics of 3 tertiary health institutions. Information requested included patients' opinion about consent process, capturing equipment, distribution and accessibility of medical photographs. The use of non-identifiable medical photographs was more acceptable than identifiable to respondents for all purposes (P = 0.003). Most respondents were favourably disposed to photographs being taken for inclusion in the case note, but opposed to identifiable photographs being used for other purposes most especially in medical websites and medical journals. Female respondents preferred non-identifiable medical photographs to identifiable ones (P = 0.001). Most respondents (78%) indicated that their consent be sought for each of the outline needs for medical photography. Half of the respondents indicated that identifiable photographs may have a negative effect on their persons; and the most commonly mentioned effects were social stigmatization, bad publicity and emotional/psychological effects. Most of the respondents preferred the use of hospital-owned camera to personal camera/personal camera-phone for their medical photographs. Most respondents (67.8%) indicated that they would like to be informed about the use of their photographs on every occasion, and 74% indicated that they would like to be informed of the specific journal in which their medical photographs are to be published. In conclusion, non-identifiable rather than identifiable medical photography is acceptable to most patients in the studied Nigerian environment. The use of personal camera/personal camera-phone should be discouraged as its acceptance by respondents is very low. Judicious use of medical photography is therefore advocated to avoid breach of principle of privacy and confidentiality in medical practice.

Nigerian dentists' knowledge of the current guidelines for preventing infective endocarditis.

OBJECTIVE: This study assessed Nigerian dentists' knowledge of current guidelines for the prevention of infective endocarditis. MATERIAL AND METHODS: A self-administered questionnaire surveyed a cross-section of Nigerian dentists gathering information on respondent demographics, awareness of the American Heart Association current guidelines on preventing infective endocarditis and sources of knowledge regarding that guidance. Respondents indicated: a) whether or not they would prescribe antibiotics before dental treatment in 10 cardiac conditions, b) if antibiotic prophylaxis was reasonable before 10 dental procedures in an endocarditis high-risk patient, and c) a prescription for oral antibiotics for an endocarditis high-risk non-allergic adult about to undergo a dental procedure. RESULTS: Respondents numbered 173 and 41% were aware of the guidelines. Most commonly the sources of this knowledge were undergraduate/postgraduate education. Overall, the correct responses for the 10 cardiac conditions was very low (33%), ranging from 94% for prosthetic heart valves (94.2%) down to 4% for previous coronary artery bypass (3.5%). For clearly invasive procedures, 80% to 96% of respondents indicated that a prophylactic antibiotic was reasonable. For clearly non-invasive procedures, 89% to 92% indicated that antibiotics were not reasonable. Correct antimicrobial agent, dose and timing of administration were prescribed by 89%, 9%, and 57% respectively. CONCLUSIONS: A low level of knowledge of the current guidelines was found among Nigerian dentists. Although, most prescribed the correct antimicrobial agent, the numbers prescribing correct dose and time of administration were quite low. Therefore, attempts should be made to teach the current guidelines in Nigerian undergraduate/postgraduate dental education.

A survey of facial nerve dissection techniques in benign parotid surgery among maxillofacial and ear, nose, and throat surgeons in Nigeria.

OBJECTIVE: The aim of the present study is to identify the facial nerve dissection technique routinely used during parotidectomy for benign parotid tumors by Nigerian Oral and Maxillofacial (OMF) and Ear, Nose, and Throat (ENT) Surgeons. MATERIALS AND METHODS: A questionnaire-based study was conducted among Oral and Maxillofacial and Ear, Nose, and Throat Surgeons in Nigeria, on their experience with antegrade and retrograde facial nerve dissection techniques in parotid surgery. The respondents were asked to indicate their choice of dissection techniques in revision parotidectomy, limited superficial parotidectomy, and in obese patients with large tumors. They were also asked to indicate if they routinely used perioperative facial nerve monitoring devices in parotid surgery for benign tumors. RESULT: About half (47.5%) of them routinely used the antegrade technique, while only a few (12.5%) used the retrograde technique. A large number of them (40%), however, used a combination of antegrade and retrograde routinely. Technical ease was the main reason for the choice of technique. The antegrade technique was the technique of choice by most respondents for revision parotidectomy (60%) and limited superficial parotidectomy (62%). However, the retrograde approach was the technique of choice by most of them (47%) in case of parotidectomy in obese patients with large tumors. The routine use of perioperative facial nerve monitoring devices is an uncommon practice among OMF and ENT surgeons in Nigeria. CONCLUSIONS: The antegrade approach for facial nerve dissection is the most common technique used in parotid surgery by Nigerian OMF and ENT surgeons. Nigerian surgeons need to consider the retrograde approach in selected cases of parotid surgery especially for localized tumors that are amenable to limited superficial parotidectomy. Inclusion of perioperative facial nerve monitoring devices is also advocated.

Oral cancer education in dental schools: knowledge and experience of Nigerian undergraduate students.

The objective of this study was to determine the knowledge and experiences of clinical dental students of the College of Medicine, University of Lagos, Nigeria related to the management and prevention of oral malignancy and premalignancy. A self-administered questionnaire was distributed to all clinical dental students. Most of the students (87.7 percent; n=57) had witnessed at least a patient with oral malignancy, while 61.5 percent (n=40) had witnessed or examined a patient with oral premalignancy. While 61.5 percent of the students had observed biopsies of malignant and premalignant lesions, only 13.8 percent (n=9) had ever performed one under supervision. All the respondents believed that oral malignancy is always or sometimes associated with pain, and most of the students were more familiar with the late signs of oral malignancy than the early signs. Almost two-thirds (64.6 percent) of the respondents believed that oral screening programs were effective for early diagnosis and management of oral malignancies. This study revealed a need for a more structured teaching program with increased emphasis on the early signs and symptoms of oral malignancies and involvement of the students in the examination and biopsies of malignant and premalignant lesions.
