RESUMO

Background: Aminoglycosides, such as Streptomycin, are cheap, potent antibiotics widely used Sub-Saharan Africa. However, aminoglycosides are the commonest cause of ototoxicity. The limited prospective epidemiological studies on aminoglycoside ototoxicity from Sub-Saharan Africa motivated this study to provide epidemiological information on Streptomycin-induced ototoxicity, identify risk factors and predictors of ototoxicity. Method: A longitudinal study of 153 adults receiving Streptomycin-based anti-tuberculous drugs was done. All participants underwent extended frequency audiometry and had normal hearing thresholds at baseline. Hearing thresholds were assessed weekly for 2 months, then monthly for the subsequent 6 months. Ototoxicity was determined using the ASHA criteria. Descriptive statistics were used to analyze socio-demographic variables. Ototoxicity incidence rate was calculated, and Kaplan-Meier estimate used to determine cumulative probability of ototoxicity. Chi-square test was done to determine parameters associated with ototoxicity and Cox regression models were used to choose the predictors of ototoxicity. Results: Age of participants was 41.43 ± 12.66 years, with a male-to-female ratio of 1:0.6. Ototoxicity was found in 34.6% of the participants, giving an incidence of 17.26 per 1,000-person-week. The mean onset time to ototoxicity was 28.0 ± 0.47 weeks. By 28th week, risk of developing ototoxicity for respondents below 40 years of age was 0.29, and for those above 40 years was 0.77. At the end of the follow-up period, the overall probability of developing ototoxicity in the study population was 0.74. A significant difference in onset of ototoxicity was found between the age groups: the longest onset was seen in <40 years, followed by 40-49 years, and shortest onset in ≥50 years. Hazard of ototoxicity was significantly higher in participants aged ≥50 years compared to participants aged ≤40 years (HR = 3.76, 95% CI = 1.84-7.65). The probability of ototoxicity at 40 g, 60 g and 80 g cumulative dose of Streptomycin was 0.08, 0.43 and 2.34, respectively. Age and cumulative dose were significant predictors of ototoxicity. Conclusion: The mean onset time to Streptomycin-induced ototoxicity was 28 weeks after commencement of therapy. Age and cumulative dose can reliably predict the onset of Streptomycin-induced ototoxicity. Medium to long term monitoring of hearing is advised for patients on aminoglycoside therapy.

RESUMO

Background: This study aimed to analyze multicenter patterns in cleft deformity surgeries and identify factors associated with the timing of primary cleft repair in Nigeria. Methods: A cross-sectional study of children managed for clefts from January 2009 to December 2020 at three Smile Train partner tertiary institutions situated in the east (Enugu), west (Ibadan), and northern (Jos) parts of the country using a prospectively collected database. Outcomes were the types of surgery performed, yearly volume of surgeries, methods of repair, and time of surgery (early versus late). Results: Of 1043 cleft surgeries, nearly half (45.7%) involved infants (<12 months). Primary repairs of the lip or palate were performed in 83.4% of cases, with 58.4% for lip repairs and 25.1% for palate repairs. The most common cleft lip repair method was a variant of Millard rotation advancement flap. Over the study years, there was a shift from von Langenbeck palatoplasty to methods such as Bardach's palatoplasty and intravelar veloplasty. Patients with bilateral cleft lip defects were significantly more likely (P < 0.001) to undergo early repairs compared with those with unilateral defects. Late primary cleft lip repairs were significantly (P < 0.001) more common in Enugu. Conclusions: This study highlights the variability in cleft surgery patterns in Nigeria. Late primary cleft surgeries were associated with less severe cleft lip or cleft palate and were more prevalent in Enugu, Southeastern Nigeria. The findings contribute valuable insights for optimizing surgical approaches and resource allocation in the management of cleft deformities in the region.

RESUMO

Background: Preoperative localisation of perforators aids in easy intraoperative dissection. Infrared thermography is a simple, safe, and effective tool with a short learning curve that is useful in identifying perforators. It has been found to have a high concordance rate when compared with computed tomography angiography and is useful in identifying arterial perforators in the leg. Objectives: To create a thermographic map of arterial perforators in the leg and to determine the correlation between the number of perforators identified and the length of the leg. Materials and Methods: This was a cross-sectional study. The length of the leg was measured and the location of perforators corresponding to the distribution of the anterior tibial, posterior tibial, and peroneal arteries was identified using thermography. The mean number of perforators corresponding to the different surfaces of the leg was noted, this was then correlated with the length of the leg using the Pearson correlation coefficient. Results: Using thermography, perforators were identified along a line drawn from the medial malleolus to the medial tibia plateau and from the lateral malleolus to the head of the fibula and within 2 cm of these lines. More perforators were found in the middle third of the leg and there was no significant correlation between the number of perforators and the length of the leg. Conclusion: A useful surface marking to aid the identification of perforators in the leg using infrared thermography was found. There was no significant correlation between the length of the leg and the number of perforators.

RESUMO

Introduction: Patients with head and neck skin cancer experience adverse functional, psychosocial, and financial impacts as a result of the disease and/or its treatment. This study aimed at evaluating the pattern of presentation, clinical outcomes, and quality of life of patients with head and neck skin cancer. Materials and Methods: A retrospective cross-sectional study of patients with head and neck skin cancer presenting to the Department of Plastic, Reconstructive & Aesthetic Surgery of the University College Hospital, Ibadan, from January 2017 to December 2021. Data obtained from the clinical records included sociodemographic characteristics, clinical and surgical details, as well as clinical outcomes. Quality of life was assessed using EORTC QLQ-C30 questionnaires. Data were summarized using descriptive statistics. Results: Nineteen patients were reviewed with a median age of 38 years (ranging from 18 to 85 years) and a male-to-female ratio of 1:1.4. Eight (42.1%) of the patients were albinos. Squamous cell carcinoma was the predominant histologic type (63.2%), while the scalp was the commonest location (42.1%). Only one patient (5.3%) presented with metastatic disease. A greater percentage of treated patients, eight (61.5%), had surgery as the only treatment modality. After a mean follow-up period of 33 months, a recurrence rate of 10.5% (two patients) and a mortality rate of 15.8% (three patients) were recorded. Quality of life assessment revealed an adverse financial impact of the disease on our patients. Conclusion: Although albinism is a recognized risk factor for skin cancers, head and neck skin cancers can occur in the dark-skinned.

RESUMO

The coronavirus disease and the subsequent pandemic that followed drastically changed human civilization with disruptive effects on health and overall wellbeing of mankind. This disruptive effect has been shown to include changes in epidemiology of burn injuries. This study therefore aimed to determine the impact of covid-19 on acute burn presentation at the University College Hospital (UCH), Ibadan. This was a retrospective study carried out between April 1, 2019 and March 31, 2021. The period was divided into two: April 1, 2019 to March 31, 2020 and April 1, 2020 to March 31, 2021. Data obtained from the burn unit registry were analyzed using the Scientific Package For Social Sciences version 25. The only statistically significant finding from this study was the marked reduction in burn ICU admission during the pandemic (P < 0.001). A total of 144 patients presented to the burn intensive care unit at UCH, Ibadan during the period under review with 92 patients in the prepandemic year, and 52 patients in the pandemic year. Patient group from 0- to 9-year-olds representing 42% in prepandemic, and 30.8% in the pandemic period was the most affected age group. Scald was predominantly among the pediatric age group in both groups. Males were more likely to suffer flame burn in both study periods with a near gender equilibration during the pandemic. Burn injury during the pandemic resulted in more total body surface area burned. The lockdown effect of the pandemic resulted in a significant reduction in acute burn admissions at the UCH, Ibadan.

RESUMO

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.

RESUMO

Introduction: There has been a significant improvement in the outcome of treatment of large surface area burns in developed countries. A major contributory factor is an early excision and skin grafting of burn wounds. The initial coverage of large surface area deep burn wounds requires the use of temporary skin substitutes such as allografts due to limited skin autografts. Cadaveric skin allografts are the commonest source of skin allografts in use; however, there may be religious, cultural, cost, or other factors mitigating its availability and routine use in low- and middle-income countries (LMICs). Human skin allografts may be used fresh or stored in tissue banks to ensure its ready availability. The purpose of this review is to promote glycerolised skin allografts as a means of skin preservation in low-resource countries above other modalities cryopreservation due to its cost advantages and relative ease of operation. Materials and Methods: A literature search for articles related to human skin allograft use in burn care, skin banks, and glycerolised skin allografts in LMICs was done using PubMed, EMBASE, and Web of Science databases. The key words used were 'allograft' and 'burn' with a filter in the search for human studies. The relevant references in the articles obtained were also searched for and included in the review. Results: Sixty-three journal articles were reviewed for contents in line with the objectives of this study. Conclusion: Glycerolised skin graft is a viable option for coverage of extensive burns in LMICs.

RESUMO

Gynaecomastia refers to the enlargement of the male breast. It can be psychologically disturbing for children and adolescents as well as adults. While in children watchful waiting is advised as the gynaecomastia could resolve, surgical intervention becomes necessary where there is significant psychosocial disturbance. We present a case of an African child whose quality of life improved after correcting the gynaecomastia. We highlight the concentric mastopexy method in the surgical management of gynaecomastia.

RESUMO

BACKGROUND: Africa, with the largest number of paediatric burns needs to focus more attention on paediatric burn survivors. Burn injury truncates schooling in child and adolescent burn patients. The aim of this study was to determine the time to return to school and factors influencing this in child and adolescent burn patients. METHODOLOGY: A cross-sectional study of child and adolescent patients aged one to nineteen years that had been managed for bun injuries. Demographic variables were obtained from archived computerized data. Phone interviews were conducted to obtain time to return to school variables using a questionnaire. Descriptive statistics, students t test, fishers exact test and Chi square test were uses as appropriate for analysis on data on SPSS version 23. A p value <0.05 was considered statistically significant. RESULTS: Thirty-one patients were recruited for the study. There was a female preponderance, 19 (61.3%). The mean age of the patients was 7.2 (±5.3) years. Scald injuries were the commonest [N = 14 (45.2%)] cause of burn. The mean Total Burn Surface Area (TBSA) was 14.1 (±12.0)%. The mean length of hospital stay was 30 (±59) days. The mean time to return to school after discharge from the hospital was 8.4 (±8.7) weeks. The occurrence of burns on the trunk was significantly (p = 0.048) associated with an earlier time to return to school. CONCLUSION: Time to return to school from burn injury and from discharge in child and adolescent burn survivors in this study are at least three times longer than previous studies. The burn care team needs to consider school re-entry programs for these children.

RESUMO

BACKGROUND/OBJECTIVES: Keloids are reportedly rare at the extremes of life. We sought to describe the epidemiology of pediatric keloids seen at the plastic surgery outpatient department of the University College Hospital, Ibadan. METHODS: We retrospectively reviewed all children younger than 19 years who presented with nonburn keloids between 2008 and 2014. Data were obtained on age; duration, size, and location of the keloid; family history; mode of treatment; and outcome. Outcome variables were recurrence and wound complications. Data were analyzed using the Pearson chi-square test for discreet variables and the independent-sample t test for continuous variables. P < .05 was taken as statistically significant. RESULTS: Within the review period, 304 patients presented with keloids, of whom 40 (13.1%) were younger than 19 years. There was a female preponderance (n = 23, 57.5%). The mean age at onset of the keloid was 9.3 years (range 3 months-18 years). Thirty (75%) patients had keloids in the head and neck region. Keloids were sporadic in 31 (77.5%) patients. Nineteen (47.5%) patients had multimodal treatment for keloid. The recurrence rate was 20%. Recurrence was significantly associated with the size of the lesion (P = .003). CONCLUSION: Keloids during childhood are not rare. More attention should be paid to the management of keloids in this age group.

RESUMO

Keloids result from abnormal proliferative scar formation with scar tissue expanding beyond the margin of the original wound and are mostly found in individuals of sub-Saharan African descent. The etiology of keloids has not been resolved but previous studies suggest that keloids are a genetically heterogeneous disorder. Although possible candidate genes have been suggested by genome-wide association studies using common variants, by upregulation in keloids or their involvement in syndromes that include keloid formation, rare coding variants that contribute to susceptibility in non-syndromic keloid formation have not been previously identified. Through analysis of whole-genome data we mapped a locus to chromosome 8p23.3-p21.3 with a statistically significant maximum multipoint LOD score of 4.48. This finding was followed up using exome sequencing and led to the identification of a c.1202T>C (p.(Leu401Pro)) variant in the N-acylsphingosine amidohydrolase (ASAH1) gene that co-segregates with the keloid phenotype in a large Yoruba family. ASAH1 is an acid ceramidase known to be involved in tumor formation by controlling the ratio of ceramide and sphingosine. ASAH1 is also involved in cell proliferation and inflammation, and may affect the development of keloids via multiple mechanisms. Functional studies need to clarify the role of the ASAH1 variant in wound healing.

RESUMO

BACKGROUND: Chronic wounds are a drain on resources both for the patient and health institution. Management of chronic wounds based on evidence-based practice requires baseline data for adequate planning. OBJECTIVES: This study was carried out to determine the point prevalence of chronic wounds in a tertiary hospital (University College Hospital, Ibadan, Nigeria) and utilize this information for subsequent wound care planning. METHODS: The study was carried out within a 1-month period and included all patients seen in the hospital with chronic wounds. The data obtained was entered into a designed form and was subsequently analyzed. RESULTS: There were 48 patients with 78 wounds representing approximately 11% of patients seen in the Department of Plastic, Reconstructive, and Aesthetic Surgery each month. Their ages ranged from 3 months to 80 years; the median age was 48 years. The male to female ratio was 1.6 to 1. The duration of the wounds ranged from 6 weeks to 780 weeks; the median duration of the wounds was 10 weeks. The area of the wounds ranged from 1 cm(2) -1,248 cm(2) (median 24 cm(2)). The most common chronic wounds were diabetic wounds, followed by pressure ulcers, postinfection ulcers, posttraumatic ulcers, burn wounds, malignant ulcers, and venous ulcers. CONCLUSION: The point prevalence data serves as a basis for wound care planning. This, in turn, should result in improved wound management grounded in evidence-based practices.

RESUMO

OBJECTIVE: Inhalation injury is an acute respiratory tract insult caused by direct thermal injury, carbon monoxide poisoning, or toxic chemical inhalants, such as fumes, gases, and mist. The aim of this study is to review the authors' experiences in a regional burn unit in a developing country. METHODS: The University College Hospital, Ibadan, Nigeria prospective burn unit database was retrospectively reviewed from January 2001 to December 2013 and analyzed using SPSS software, version 16 (SPSS Inc, Chicago, IL). RESULTS: There were 840 patients in all, 63% (527) had cutaneous burns only, while 37% (313) had associated inhalation injury. There was a male preponderance in both groups. Those with cutaneous burns only and those with associated inhalation injury had a male to female ratio of 1.6:1 and 1.5:1, respectively. The mean ages were 26 years ± 18 years (inhalation injury) and 21 years ± 17 years (cutaneous burn only) (P less than 0.05). The mean total body surface area (TBSA) of the burn injuries was 55% (inhalation injury) and 25% (cutaneous burn only) (P less than 0.05). Burn injury occurred most frequently between 19.00 hours and 24.00 hours, and 56% of burn injuries that occurred during this time were associated with inhalation injury (P less than 0.05). Major causes of burns were flames and scalding (86.2%). Mortality was 71% in patients with inhalation and 26% in patients with cutaneous burns only (P less than 0.05). CONCLUSION: The association of inhalation injury with cutaneous burns portends a grave condition. An upgrade of expertise and infrastructure in the management of these patients is necessary in order to improve outcomes.

RESUMO

BACKGROUND: The anecdotal fear of using cautery for surgical incisions is still common in surgical practice despite recent evidences. The aim of this study is to compare the results of electrocautery and the scalpel in skin incisions. MATERIALS AND METHODS: This is a prospective randomized double blind study conducted in the Department of Surgery, of a teaching hospital in Ibadan. Patients were randomized to have either scalpel or electrocautery incisions. The duration used in making the skin incision; the incisional blood loss and the ensuing length and depth of the wound were noted. Postoperative pain; duration of wound healing and the occurrence of surgical site infection were also noted. RESULTS: There were 197 patients consisting of the scalpel group (n = 98) and the electrocautery group (n = 99). The ages ranged from 16 to 73 years. The demography, case distribution and body mass index were similar in both groups. The mode of presentation was predominantly elective. The incision time was shorter in the electrocautery group (P < 0.001). The blood loss was less with the diathermy compared to the scalpel (6.53 ± 3.84 ml vs. 18.16 ± 7.36 ml, P < 0.001). The cumulative numerical rating scale score for pain was 12.65 (standard deviation [SD] 8.06) and 17.12 (SD 9.49) in the diathermy and scalpel groups respectively (P < 0.001). There was no statistically significant difference in wound infection and wound closure (epithelialization time) (P = 0.206). CONCLUSION: The use of electrocautery in making skin incision is associated with reduced incision time, incisional blood loss, and postoperative pain.

RESUMO

BACKGROUND: More involvement of sub-Saharan African countries in biomedical studies, specifically in genetic research, is needed to advance individualized medicine that will benefit non-European populations. Missing infrastructure, cultural and religious beliefs as well as lack of understanding of research benefits can pose a challenge to recruitment. Here we describe recruitment efforts for a large genetic study requiring three-generation pedigrees within the Yoruba homelands of Nigeria. The aim of the study was to identify genes responsible for keloids, a wound healing disorder. We also discuss ethical and logistical considerations that we encountered in preparation for this research endeavor. METHODS: Protocols for this bi-national intercultural study were approved by the Institutional Review Board (IRB) in the US and the ethics committees of the Nigerian institutions for consideration of cultural differences. Principles of community based participatory research were employed throughout the recruitment process. Keloid patients (patient advisors), community leaders, kings/chiefs and medical directors were engaged to assist the research teams with recruitment strategies. Community meetings, church forums, and media outlets (study flyers, radio and TV announcements) were utilized to promote the study in Nigeria. Recruitment of research participants was conducted by trained staff from the local communities. Pedigree structures were re-analyzed on a regular basis as new family members were recruited and recruitment challenges were documented. RESULTS: Total recruitment surpassed 4200 study participants over a 7-year period including 79 families with complete three-generation pedigrees. In 9 families more than 20 family members participated, however, in 5 of these families, we encountered issues with pedigree structure as members from different branches presented inconsistent family histories. These issues were due to the traditional open family structure amongst the Yoruba and by beliefs in voodoo or in juju. In addition, family members living in other parts of the country or abroad complicated timely and complete family recruitment. CONCLUSIONS: Organizational, logistics and ethics challenges can be overcome by additional administrative efforts, good communication, community involvement and education of staff members. However, recruitment challenges due to infrastructural shortcomings or cultural and religious beliefs can lead to significant delays, which may negatively affect study time lines and expectations of funding agencies.

RESUMO

The neurosurgery division in University College Hospital (U.C.H.) admits approximately one traumatic spinal cord injured (SCI) patient per week, most of whom stay a minimum of 42 days on admission. A common complication in these patients is the development of pressure ulcers, which contributes to a longer hospital stay and increased hospital expenses. The purpose of this study was to investigate the pattern of presentation of pressure ulcers in patients on admission and to propose policies or protocols to reduce the incidence. It is a prospective study of traumatic SCI patients managed on the neurosurgery ward from January 2003 to June 2004. The data was analysed using descriptive statistics. Sixty-seven patients were studied. The average hospital stay was 73 days. Thirteen (20%) of the patients were admitted with pressure ulcers, 32 (47·7%) developed it after admission. As much as 87·5% of pressure ulcers seen in the course of this study which occurred on admission in U.C.H. was in the first week of admission, 6·25% in the second week and the remaining 6·25% in the third week. Pressure ulcers were distributed as follows; 69% (42) in the sacral region, 18% (11) trochanteric, 5% (3) scalp, 1·5% (1) ankle, 1·5% (1) ischial tuberosity, the remaining 5% in other sites. Preventive measures for pressure ulcers consisted of basic skin care, pressure dispersion using fenestrated foams and alternating weight-bearing sites by regular turning. Pressure ulcers are commonest in the sacral and gluteal regions and tend to occur within the first week of admission in the neurosurgical wards.

RESUMO

Keloids develop when scar tissue responds to skin trauma with proliferative fibrous growths that extend beyond the boundaries of the original wound and progress for several months or years. Keloids most frequently occur in individuals of indigenous sub-Saharan African origin. The etiology for keloids is still unknown and treatment can be problematic as patients respond differently to various treatment modalities. Keloids have a high rate of recurrence following surgical excision. Some West African patients claim to have had successful outcomes with traditional African remedies-boa constrictor oil (BCO) and shea butter-leading the authors to investigate their effects on cultured fibroblasts. The effects of emulsions of BCO, fish oil, isolated omega-3 fatty acids, and shea butter were tested in comparison to triamcinolone regarding inhibition of cell growth in keloid and control fibroblast cultures. In a series of controlled studies, it was observed that fish oil and BCO were more effective than triamcinolone, and that cis-5, 8, 11, 14, 17-eicosapentaenoic acid was more effective than -linolenic acid. While cell counts in control cultures continuously decreased over a period of 5 days, cell counts in keloid cultures consistently declined between day 1 and day 3, and then increased between day 3 and day 5 for all tested reagents except for fish oil. These results suggest that oils rich in omega-3 fatty acids may be effective in reducing actively proliferating keloid fibroblasts. Additional studies are warranted to investigate whether oils rich in omega-3 fatty acids offer effective and affordable treatment for some keloid patients, especially in the developing world.

BACKGROUND: Primary extra-osseous osteogenic sarcomas have been reported in many tissues of the body but their occurrence in the breast is extremely rare. It can arise as a result of osseous metaplasia in a pre-existing benign or malignant neoplasm of the breast or as non-phylloides sarcoma from the soft tissue of a previously normal breast. CASE PRESENTATION: A 40 year-old Nigerian woman was clinically diagnosed to have carcinoma of the left breast. The histology report of core-needle biopsy of the mass showed a malignant neoplasm comprising islands of chondroblastic and osteoblastic stromal cells. This report changed the diagnosis from carcinoma to osteogenic sarcoma of the breast. She had a left modified radical mastectomy, however there was significant post surgery skin deficit. A latissimus dorsi musculocutaneous flap was used to cover the anterior chest wall defect. Sections from the mastectomy specimen confirmed the diagnosis of osteogenic sarcoma. She died six months after mastectomy. CONCLUSION: A diagnosis of osteogenic sarcoma of the breast was made based on histology report and after excluding an osteogenic sarcoma arising from underlying ribs and sternum. This is the second documented case of primary osteogenic sarcoma of the breast coming from Nigeria.
