Ludwig's angina in Nigeria: The disease of the poor and health inequality!

AIM: highlight the health inequality and identify opportunities to improve the care delivered to the patients who suffer from Ludwig's angina which could have national and international clinical impact. MATERIALS AND METHODS: Data was collected from three major oral and maxillofacial centers, in Nigeria including Benin, Lagos and Kano. A protocol was developed for data collection which included demographic details, socio-economic status, management of the air way, the associated morbidities and mortalities. RESULTS: Forty-nine were managed in Benin, 57 in Lagos and 66 in Kano. Diabetes was the most prevalent underlying systematic condition, affecting 21% of the Ludwig's angina patients in Lagos. Poverty was a common denominator, 90% of the patients from Kano were unemployed compared to 23% and 8% from Lagos and Benin respectively. For most of the patients, the airway was monitored. Incision and drainage were carried out in most of the cases at Benin and Lagos, but it was only considered in 50% of the cases in Kano. Mortality ranged from 4% in Benin to 12% in Lagos and it was as high as 19% in Kano. CONCLUSION: poor access to oral healthcare, unemployment and low socio-economic status are important predisposing factors of Ludwig's angina.

Odontogenic tumours in Nigeria: A multicentre study of 582 cases and review of the literatura

BACKGROUND: The objective of this study was to classify the various types of odontogenic tumours (OTs) using the newly updated 2017 world health organization (WHO) histological typing and to analyze the prevalence of these tumours among Nigerians as well as to compare the results obtained with reports from world-wide studies. MATERIAL AND METHODS: The records of four major tertiary hospitals in Nigeria were reviewed over a 12-year (2004-2015) period. Lesions diagnosed as odontogenic tumours were classified into four groups according to the 2017 WHO histological typing. Data which consisted of age, sex and site were analyzed using SPSS for Window (version 20.0; SPSS Inc., Chicago, IL) and frequency tables were computed. RESULTS: A total of 582 OTs were recorded and reviewed, benign OTs were 573 (98.5%) cases and malignant OTs were 9 (1.5%) cases. Of the benign OTs, the epithelial OTs were the commonest (500; 86%) while the benign mixed OTs were the least frequent (21; 3.6%). The mean age was 30±14 years (age range of 3-77 years) and the peak age was in the third decade (197; 33.8%) of life. There was slight male gender and strong mandibular site predilection. Ameloblastoma, was the most frequent OT and it accounted for 75.5% of the OTs, followed by adenomatoid odontogenic tumour (8.1%) and odontogenic myxoma (7.2%). Malignant OTs accounted for 1.5% of the OTs. CONCLUSIONS: OTs show a geographic variation with tendency for prevalence of the epithelial OTs in Africa. Ameloblastoma has a high prevalence among Nigerians and is the most common OTs in Africa. Prevalence of odontoma is relatively low in developing African countries like Nigeria when compared to the prevalence in developed countries

Quality of life of patients surgically treated for ameloblastoma.

BACKGROUND: The surgical management of ameloblastoma can have a profound functional and psychological effect on a patient's quality of life (QoL). The aim of this study was to compare the pre- and post-operative QoL outcomes of patients requiring surgical treatment for ameloblastoma. PATIENTS AND METHODS: A total number of 30 patients were identified as fulfilling the criteria for this study. They included 18 males and 12 females, aged between 14 and 47 years with a mean of 27.3 years (standard deviation 10.2). Each patient completed a modified version of the University of Washington QoL questionnaire version 4, a day to surgery and postoperatively on the 7(th) day, 3 months, and 6 months. RESULTS: Following surgical treatment of patients for ameloblastoma, the QoL decreased immediately after surgery. It then gradually improved over time and exceeded the preoperative value at 6 months postoperatively. When analyzed with respect to location, posteriorly placed tumors had the best postoperative QoL outcome. Patients expressed concern more about their appearance preoperatively while postoperative concerns were mostly focused on their ability to chew. CONCLUSION: Significant improvement occurred in QoL scores following surgical management of ameloblastoma. The small sample size utilized in this study limits a definitive conclusion. A larger multicenter study is therefore recommended.

A review of cleft lip and palate management: Experience of a Nigerian Teaching Hospital.

BACKGROUND: Cleft lip (CL) and palate (CLP) management is multidisciplinary. A cleft team was formed in a Nigerian Tertiary Hospital to address the health needs of cleft patients in the centre. AIM: This paper aims at documenting the Aminu Kano Teaching Hospital (AKTH) management protocol for orofacial clefts and also to review our experience with CLP surgeries performed at AKTH since our partnering with Smile Train. MATERIALS AND METHODS: A retrospective review of all the cleft patients surgically treated from January 2006 to December 2014 under Smile Train sponsorship was undertaken. A descriptive narrative of the cleft team protocol was also given. RESULTS: One hundred and fifty-five patients (80 males, 75 females) had surgical repairs of either the lip or palate. CL patients were 83 (53.55%), while CLP patients were 45 (29.03%) and isolated cleft palate patients were 27 (17.42%). CONCLUSION: The inclusion of various specialities in the cleft team is highly desirable. Poverty level amongst our patients frequently limits our management to surgical treatment sponsored by the Smile Train, despite the presence of other residual problems.

Quality of life following surgical treatment of oral cancers.

INTRODUCTION: Quality of life (QoL) studies provide information about the impact of disease, the treatment of symptoms, and outcomes following treatment. The present study aims to evaluate the postoperative QoL of patients treated for oral cancer in a Nigerian government tertiary hospital. MATERIALS AND METHODS: A prospective study on consenting patients with oral cancer was undertaken at Aminu Kano Teaching Hospital, Kano, Nigeria. The subjects completed the University of Washington QoL (UW-QoL) questionnaire one day prior to surgery and postoperatively after 7 days, 1 month, 3 months, and 6 months. RESULTS: Sixty-eight patients with oral cancer were recruited. Of these, 38 were males, and 30 were females (male : female, 1.3 : 1). Twenty-four patients (12 males and 12 females) underwent surgery and completed postoperative QoL assessment using the UW-QoL questionnaire. Preoperative QoL mean score was 2.21, while postoperative mean scores after 1 week, 1 month, 3 months, and 6 months were 3.67, 3.46, 2.82, and 2.61, respectively. CONCLUSION: An improvement in QoL following surgical treatment for patients with oral cancer was observed. 'Appearance,' 'recreation,' and 'chewing' were identified as the most important determinants of postoperative QoL in patients with oral cancer in our study.

A two-year audit of non-vascularized iliac crest bone graft for mandibular reconstruction: technique, experience and challenges.

OBJECTIVES: Non-vascularized iliac crest bone graft (NVIBG) is a known treatment option in mandibular reconstruction following jaw resection, but no documented review of patients treated with NVIBG exists for northern Nigeria. The experience and technique from a Nigerian tertiary hospital may serve as baseline data for comparison and improvement of practice for other institutions. MATERIALS AND METHODS: A retrospective review of medical records and patient case files from January 2012 to December 2013 was undertaken. All case files and other medical records of patients who had reconstruction with NVIBG for benign or malignant lesions with immediate or delayed reconstruction were selected for review. RESULTS: Twenty patients had mandibular reconstruction with NVIBG during the study period. Two patients were excluded because of incomplete medical records. Eighteen patients' (male=14, female=4) records were reviewed. Their ages ranged from 13 to 62 years (mean 26.0±10.6 years). Indications for NVIBG included jaw tumors (n=16; 88.3%), jaw cyst (n=1; 5.6%) and gunshot injury (n=1; 5.6%). Jaw tumors seen were ameloblastoma (n=15; 83.3%) and osteosarcoma (n=1; 5.6%). Treatments done were mandibular resection with condylar resection (n=7; 38.9%), mandibular segmental resection (n=10; 55.6%) and subtotal mandibulectomy (n=1; 5.6%). Patients' postoperative reviews and radiographs revealed good facial profile and continued bone stability up to 1 year following NVIBG. CONCLUSION: NVIBGs provide an acceptable alternative to vascularized bone grafts, genetically engineered bone, and distraction osteogenesis for mandibular reconstruction in resource-limited centers.
