The incidence and prevalence of chronic wounds from a major plastic surgery service from a metropolitan city in south western Nigeria: A sixteen-year retrospective review.

INTRODUCTION: Chronic wound presents a burden to the patient due to the effect on their quality of life and cost of care. The exact prevalence is difficult to assess due to insufficient data, different study designs, and deferent study definitions of chronic wounds. There is limited data on the prevalence and the burden of chronic wound in our subregion. This study was therefore carried out to establish the burden of chronic wound in order to document a baseline data for monitoring progress, as well as provide information for advocacy on equitable distribution of resources for wound care. METHOD: This was a retrospective review between January 2007 and December 2022. Data was analysed using SPSS. RESULT: A total of 866 patients with new chronic wounds were seen at an average of 54 cases per year. An average of 330 old and new chronic wounds are seen yearly. Chronic ulcers are developing at a rate of 1.2/1000 population, and the prevalence of chronic ulcer is 3.3/1000 population. Most patients were males (57.2 %), with a mean age of 41.7years ± 20.6. Post traumatic wound is the leading aetiology. Age correlates positively with aetiology, p=<0.001. Sickle cell and venous wounds are predominantly on the legs, p=<0.001. There is a correlation between increasing age and occurrence of chronic wound in the leg, p=<0.001. CONCLUSION: Post traumatic wound is the leading cause of chronic wound in our subregion. There is a need to improve care of acute wounds to reduce the burden of chronic wounds.

Differences in burn wound size estimation between points of referral and the burn unit: experience at a major burn center in southwestern Nigeria.

BACKGROUND: Accurate burn wound size estimation is important for resuscitation and subsequent management. It is also important for the development of referral guidelines in Nigeria. OBJECTIVE: To establish whether a significant discrepancy exists in burn size estimation between referral centers and burn units. METHODS: A retrospective review of burn patients managed at the burn unit of a premier tertiary hospital in Ibadan, southwestern Nigeria, between January 1, 2016, and October 31, 2019 was conducted. Patients' demographic and other characteristics, inclusive of TBSA estimation from point of referral and the burn unit, were retrieved and analyzed. RESULTS: A total of 96 burn injury records were found for the study period, with a male-to-female ratio of 1.3:1. Thirty-five records (36.5%) included no burn size estimation by the referring physician. There was a statistically significant difference in TBSA estimation between referring physicians and burn unit physicians (P = .015). Burn wounds were more likely to be overestimated than underestimated (P = .016). Overestimation is more likely with minor burns and in pediatric patients. Underestimation was more likely in adults. CONCLUSION: There is a significant difference in burn size estimation between burn unit physicians and referring physicians. This finding underscores the need for continuous education on burn estimation to aid proper referral and management.

Current Trend in the Epidemiology of Thermal Burn Injury at a Tertiary Hospital in South Western Nigeria.

Worldwide, thermal burn is the leading etiological type of burn injury accounting for 86% of burn injuries requiring admissions. Flame, Scald, and contact burn are the leading causes of thermal burn. Changes in the sociodemographic characteristics of societies have led to alterations in the epidemiology of burn. An understanding of such changes in the epidemiology of burn is essential in formulating and executing adequate burn prevention programs. We sought to establish the current trend in the etiology, gender distribution, age, occurrence of inhalation injury, burn surface area, burn depth, and mortality rate of thermal burns at Ibadan. This was a retrospective study carried out between January 2013 and December 2022. Thermal burns constitute 92% of burn injuries. The male-to-female ratio was 1.4:1. There were 265 (45%) patients in the pediatric age group and 323 adults (55% of the patients). The proportion of flame, scald, and contact burns were 378 (58%), 203 (32%), and 14 (2%), respectively. Flame burns resulting from liquified petroleum gas (LPG) explosion show a rising trend, with a decline in flame burns from kerosene (P < .001). One hundred and ninety (32%) patients had inhalation injury. The overall mortality was 19% (N = 114). Kerosene flame, 38% (17 of 45 patients), and LPG, 32% (41 of 130 patients), were the most lethal causes of flame injuries (P < .043). The study shows the increasing contribution of LPG to the etiology of thermal burn injuries. Burn prevention programs should target safe use of LPG stoves and cylinders.

Changing Epidemiology and Outcome of Pediatric Thermal Burn Injury in South Western Nigeria.

The pediatric age group has been noted to be particularly vulnerable to burn injuries. Burn is the fifth most common cause of childhood injuries. Nigeria has a very young population with a median age of 18.1 years. Scald is the most common form of burn injuries in this age group globally; however, previous reports from our institution found flame to be the most common form of burn in pediatric age. The most recent report from 13 years ago still maintained flame as the most common cause of pediatric burn injury. This study was carried out to determine the changes in epidemiology and outcome of pediatric thermal burn injury. This was a retrospective study carried out between January 2013 and December 2022. Data were analyzed using the statistical package for social sciences software version 23. The significance was set at a P-value of .05. Two hundred and sixty-five children presented with thermal burn with a male-to-female ratio of 1.3:1. 63.4% occurred in children 0-5 years. Scald (59.6%) was the most common cause of injury. Most flame injuries in females were due to liquified petroleum gas cookstove explosion, while petrol explosion was the most common cause in males (P ≤ .001). There is a yearly increase in burn depth (P = .009). Most inhalation injuries occurred in those aged 11-16 years (P = .006). Mortality rate was 10.2%, with total body surface area burned (P ≤ .001), burn depth (P ≤ .001), and inhalation injury (P ≤ .001) associated with increasing mortality. Scald is now the most common cause of thermal burn in our institution, with a remarkable reduction in mortality rate.

Experience with Liposuction for the Treatment of Subcutaneous Lipoma: A Case Series from a Tertiary Health Institution in Nigeria.

Background: Lipomas are the commonest benign tumours in the body. Treatment is often by excision biopsy. Liposuction has traditionally been used for body sculpturing, but recently, it was introduced for the operative management of lipomas. The aim of this study was to present our experience with liposuction lipectomy-assisted lipoma aspiration in terms of its efficacy, complications, risk of recurrence, and patient satisfaction. Materials and Methods: A retrospective review of 16 patients with solitary or multiple lipomas managed with liposuction over a 5-year period was done. All the patients had a prior fine needle aspiration cytology, which was reported as benign. Informed consent was obtained, and the procedures were performed as a day case under tumescent anaesthesia. Lipo-aspiration was done with manual liposuction device. The patients were discharged on oral analgesics and antibiotics. Results: Sixteen patients (10 females and six males) with 21 lesions were managed. The median age was 43 years (23-66 years). All the patients had satisfactory outcomes. The procedure was converted to open-excisional surgery in one patient, and the histology was reported as fibro lipoma. Friction burn at the cannula site occurred in one patient, which subsequently healed with scars. No recurrence was reported in any of the patients. Conclusion: In well-selected patients, liposuction-assisted lipectomy may have an advantage over the classical open technique. All patients should have a minimum investigation of fine needle aspiration cytology because of the risk of atypical lipomas or liposarcoma, which might have similar features as subcutaneous lipoma.

Pattern of congenital hand anomalies at a tertiary plastic surgery service in South-Western Nigeria: A 10-year, cross-sectional retrospective review.

CONTEXT: Although congenital hand anomalies are among the more common musculoskeletal anomalies worldwide, we do not know its prevalence in our practice. AIMS: The aim of the study was to determine the pattern of congenital hand anomalies presenting to our tertiary plastic surgery outpatient service in South-Western Nigeria. MATERIALS AND METHODS: This is a cross-sectional retrospective analysis of outpatient cases of congenital hand anomalies presenting over a 10-year period. Descriptive and inferential statistics were performed using frequencies, Student's t-test and Chi-square as appropriate. The data were analysed using IBM SPSS Statistics 23.0. The statistical significance value was set at P < 0.05. RESULTS: One hundred and twenty-two cases were identified. The highest number of cases was seen in the year 2012, 23 patients (19.3%). There was a male preponderance of 66 patients (55.1%). Thirty-two patients (26.2%) presented as neonates and 36 (29.5%) as infants. Bilateral anomalies were seen in 67 patients (54.9%). The most common anomaly was failure of differentiation, 88 patients (72.1%) followed by duplication, 26 patients (21.3%). Syndactyly with 43 patients (35.2%) was the most common anomaly under failure of differentiation. No significant associations were found between the type of anomaly and gender or laterality. CONCLUSIONS: Syndactyly was the most common congenital hand anomaly in this study. There was a preponderance of bilateral involvement in both syndactyly and polydactyly.

The reverse sural artery flap for the reconstruction of distal third of the leg and foot.

Soft tissue defects around the distal third of the leg and the foot present a major reconstructive challenge. There is limited expertise with free tissue transfers in many developing countries, necessitating consideration of other options for the closure of such defects. The versatility and reliability of sural artery flap have made it an emerging popular option for the reconstruction of such defects. Twenty patients comprising of 13 males and 7 females with soft tissue defects of the lower third of the leg and foot requiring soft tissue cover were treated between January 2006 and December 2010. The age range was 7-58 years with a mean age of 30 years. Nineteen (95%) of the defects were post-traumatic while one (5%) was post-infective. All the defects were covered with reversed sural artery flaps, which were raised on the posterior aspect of the junction of the upper and middle third of the leg. The smallest flap was 4 × 4 cm(2) while the largest measured 20 × 12 cm(2). The donor defect was closed directly in 7 (35%) patients, while split skin graft was applied in the remaining 13 (65%) patients. There was satisfactory flap healing in 17 patients (85%), while 3 patients (15%) had complete flap necrosis. Two of these patients had significant comorbidities of haemoglobinopathy and poorly controlled diabetes mellitus. Sural artery flap remains a viable option for the reconstruction of soft tissue defects of the distal third of the leg and foot. Caution should, however, be exercised in patients with some significant systemic diseases.
