Microvascular reconstruction for complex lower-extremity trauma in pregnancy.

Microvascular reconstruction in pregnancy is rare. We report a case of complex distal lower-extremity trauma in early pregnancy reconstructed with a microvascular free muscle flap. A 30-year-old female with 13 weeks gestation had a crush avulsion of the distal left leg with medial malleolar fracture; she had two sessions of debridement, joint stabilising external fixator frame, and a vaccum assisted closure dressing application. Two weeks later, a right latissimus muscle flap was harvested. Flap was transferred to the debrided leg defect. The thoracodorsal vessels were anastomosed end to end to the anterior tibial artery and the concomitant vein. The flap was immediately revascularised. Continuous post-operative heparin infusion was administered. The muscle was covered with split-thickness skin graft 48 hrs later. Healing and post-operative recovery were uneventful. This report suggests that careful surgical and anesthetic techniques, along with a balanced post-operative anticoagulation protocol, can achieve satisfactory microvascular reconstruction in pregnancy.

Surgical resident doctors' perception of their training using Surgical Theatre Educational Environment Measure (STEEM) tool in postgraduate surgical residency training institutions in Nigeria.

Introduction: Postgraduate Medical Education is 'the constellation of learning activities carried out to enable doctors to develop relevant competencies and deeper knowledge in specific subject areas after completion of basic medical education'. The purpose of this study was to examine the perception of surgical resident doctors of their training in accredited institutions in Nigeria, using the Surgical Theatre Educational Environment Measure (STEEM) inventory. Methods: The study was a cross-sectional observational study that employed the STEEM instrument which was administered online via email to surgical resident doctors in all the surgical residency training institutions in Nigeria accredited by the National Postgraduate Medical College of Nigeria. The STEEM is a validated 40 item, self-administered questionnaire. Statistical analysis was performed using SPSS version 23. Cronbach's alpha was calculated for the whole STEEM and the sub-scales for both reliability and internal consistency. Results: One hundred and sixty-six respondents filled the questionnaire out of 464 people contacted, giving a respondent rate of 35.7%. There were 156 (94.0%) males and 10 (6.0%) female respondents. One hundred respondents (60.2%) had global STEEM scores less than the benchmark of 120, three (1.8%) with scores of 120 and 63 (38.0%) had scores >120. Conclusion: The majority of the respondents in our study indicated dissatisfaction with their operational educational environment experience.

Surgical outcomes of diabetic hand infections in Lagos, Nigeria.

Background: Hand infections in diabetics can be a major cause of functional impairment. In patients with Tropical Diabetic hand syndrome prompt surgical intervention may salvage the hand, but return to premorbid function remain a challenge. Objectives: A retrospective study of consecutive diabetic patients with hand infections was done in 2 tertiary institutions in Lagos, Nigeria to identify the epidemiology, modes of presentation, types of surgical intervention and outcomes of treatment. Results: Twenty one patients were studied over a 5 year period. ten males, eleven females. All were type 2 Diabetes. 52.4%(11) were diagnosed less than a year prior to presentation. 61.9%(13) had digit/hand gangrene on presentation. All operated patients (20) had wound debridements. 52.5% (11) digit/hand amputations and this was the commonest surgical procedures done. Other surgeries done include skin grafts and `flap reconstructions. There was a 19% mortality rate. Less than a fifth were able return to their premorbid occupation after 3 months. But all had reduced range of motion in the interphalangeal joints in the adjacent digits. Conclusions: There is a high morbidity rate for hand infections in the diabetic, even though majority of the hands were salvaged, most patients were unable to return to their premorbid occupation at 3 months.

Research experience of resident doctors who attended research methodology courses of the National Postgraduate Medical College of Nigeria.

INTRODUCTION: For over three decades, the National Postgraduate Medical College of Nigeria (NPMCN) has been vested with the responsibility of overseeing postgraduate medical training. The main objective of this study was to assess the residents' perception of research as well as challenges faced in pursing seamless research during their training. MATERIALS AND METHODS: This study was a cross-sectional descriptive survey in 2013. Self-administered questionnaires were distributed to the participants of the annual research methodology workshop in all the 15 faculties of the NPMCN. The questionnaires assessed the residents' previous exposure to research, their publication history and their trainers' input to their own research. Statistical analysis was performed using the Statistical Package for the Social Sciences version 20 software. RESULTS: Four hundred and one resident doctors, out of a total of 415 who attended the course, completed the questionnaires during the study period (96.6% response rate). There were 269 (67.0%) males and 132 (33.0%) females, giving a male-to-female ratio of 2:1. About three-quarters of them admitted that their exposure to research during training was grossly inadequate. Twenty-five percent of them were involved in a previous research before residency training, and a further 70% of respondents were involved in their trainers' research work. Ninety-four percent in our study identified a lack of dedicated time to be spared for research as a major obstacle to research. CONCLUSION: Contribution and exposure to research among postgraduate trainees in Nigeria are low. Lack of dedicated time for research was viewed as the major obstacle to research by most residents.

Is the plastibell of any haemostatic value after 24 h?

BACKGROUND: The Plastibell is the most popular circumcision method among mothers in our city. Haemorrhage is its major problem. At our centre, we have recorded many circumcision problems resulting from prolonged retention of the Plastibell ring and this study, therefore, sought to explore the ways of reducing complications resulting from prolonged retention of the ring. PATIENTS AND METHODS: This was a prospective study, in which a total of sixty consecutive male neonates were recruited with all undergoing circumcision using the Plastibell device. Thirty patients were assigned to the subject group, in whom the Plastibell ring was removed by the investigator at 24 h while the other thirty constituted the control group whose Plastibell rings were allowed to fall off on their own. The patients selected were aged between 7 and 28 days. RESULTS: Overall, 4 (6.6%) of the sixty neonatal circumcisions in this study were complicated by haemorrhage. There was minor bleeding in 3 (10%) of the thirty subjects and 1 (3.3%) of the thirty controls. There was no statistically significant difference between the groups (P = 0.3006). One patient each from the subject and control groups bled following slipped ligature a few hours after Plastibell circumcision. The other two patients in the subject group bled following the removal of the Plastibell ring at 24 h. All the bleeding episodes were effectively controlled within 5 min by firm digital pressure only administered through a piece of dry, sterile gauze. CONCLUSION: Post-circumcision haemorrhage was not significantly different between circumcised babies whose Plastibell rings were removed at 24 h and those in whom it was left to fall off on its own.

Early experiences with microvascular free tissue transfer in lagos, Nigeria.

OBJECTIVES: Microvascular free tissue transfer within our subregion is fraught with considerable challenges. We aim to highlight our experiences gained with our first fifteen cases of microvascular free tissue transfer at the Lagos University Teaching Hospital. We believe our report will be useful to colleagues embarking on such reconstructions in similar settings. MATERIALS AND METHODS: The clinical records of the first 15 cases of free flaps done at our center were reviewed. The indications for surgery, choice of flap, recipient vessels, duration of surgery and complications were noted. RESULTS: Fifteen cases were done, 10 flaps survived, ten defects occurred following trauma while remaining five followed cancer resections. Anterolateral thigh and radial forearm flaps were the most common flap used. The mean duration of surgeries was 7.1 hours SD ± 1.10 hours. Our take back rate was 13.3%, with a salvage rate of 50%. Three flaps failed on account venous congestion while remaining two failed due to arterial occlusion. CONCLUSION: 66.67% free flap success rate recorded reflect our early experiences in our institution. We believe meticulous planning, careful vessel selection, close flap monitoring as well as improved infrastructural support can lead to much better success rates in microvascular reconstruction in our country.

Prevalence and bacteriology of bacteremia associated with cleft lip and palate surgery.

The aim of the study was to determine the prevalence and bacteriology of bacteremia associated with cleft lip and palate (CLP) surgery. Three venous blood samples were obtained from 90 eligible subjects who presented for CLP surgery: before surgical incision, 1 minute after placement of the last suture, and 15 minutes thereafter. The samples were injected into an Oxoid Signal blood culture and transported to the laboratory for gram-positive/negative and aerobic/anaerobic bacteria analysis. Prevalence of bacteremia associated with cleft surgery was 38.1%. Prevalence rates of bacteremia in cleft lip surgery, cleft palate surgery, and alveoloplasty were 40.9%, 33.3%, and 50%, respectively. There was no significant difference in prevalence rate of positive blood culture in cleft lip surgery, cleft palate surgery, and alveoloplasty (P = 0.69). Positive blood culture was detected most frequently (47%) 1 minute after placement of the last suture. Of the 23 subjects who had positive blood culture at 1 minute, bacteremia persisted in 8 (35%) of them after 15 minutes. The most common bacteria isolated were coagulase-negative staphylococcus, Acinetobacter lwoffii, and coagulase-positive Staphylococcus aureus. Sex and age of the subjects, duration of surgery, blood loss, and type of cleft surgery were not significantly associated with positive blood culture. Bacteremia associated with CLP surgery is polymicrobial and persisted for at least 15 minutes after surgery in 35% of cases. This may reinforce the need for prophylactic antibiotics to protect at-risk patients from developing focal infection of the heart by oral flora.

Differential diagnosis and management of giant fibroadenoma: comparing excision with reduction mammoplasty incision and excision with inframammary incision.

Giant fibroadenoma (GFA) may present with breast asymmetry and can be excised with an inframammary incision (IFI) or reduction mammoplasty incision (RMI). This study investigated the clinical presentation and compared excision with the IFI and RMI. All patients with benign breast tumours greater than 5 cm underwent core needle biopsy and a histopathological diagnosis. All confirmed GFA had their clinical details documented and randomised into two groups for excision with an IFI or RMI. Twenty-two patients were studied. The age range was 12-46 years, mean 21.18 ± 2.22 years. The patients were divided into two groups: a juvenile group (n = 16) (73%) aged 12-18 years, mean age 14.06 ± 0.42 years, and a perimenopausal group (n = 5) aged 28-46 years. The juvenile group showed cyclic increases in breast size monthly with menstruation while the perimenopausal showed an initial slow growth of 6-24 months followed by a rapid growth. Fifteen patients (68%) had excision biopsy with IMI and seven patients with RMI. Seven of the patients treated with IFI had minimal preoperative asymmetry and satisfactory aesthetic outcome. Among the patients with severe preoperative asymmetry treated with IFI (n = 8) and RMI (n = 7), those treated with IFI had persistent postoperative skin redundancy and asymmetry, which was not found in those treated with RMI. In conclusion, for patients with significant asymmetry, excision with the IFI was associated with persistent asymmetry while excision with RMI was associated with restoration of symmetry.

The epidemiology and management of gynatresia in Lagos, southwest Nigeria.

OBJECTIVE: To document data from patients presenting with gynatresia at 2 tertiary health centers in Lagos, southwest Nigeria. METHODS: In a prospective, descriptive study, clinical history and physical examination data were collected for women who presented with gynatresia between January 2004 and January 2011. Ultrasonography results and abnormality at surgery were also documented. Where possible, the severity of stenosis and surgical outcome were assessed by published scales. RESULTS: Forty-seven patients were included in the study. Eight patients (17.0%) presented with congenital gynatresia, the commonest cause of which was Mayer-Rokitansky-Küster-Hauser syndrome (4 patients, 50%). Thirty-nine patients (83.0%) presented with acquired gynatresia, the main cause of which was herbal pessaries (30 patients, 76.9%). Herbal pessaries were used to treat fibroids (23 patients, 76.7%), uterovaginal prolapse (3, 10.0%), and infertility (2, 6.7%); and to procure abortion (2, 6.7%). The ages of the patients who used herbal pessary ranged from 18 to 50 years (mean 36.10 ± 1.24 years). Other causes of acquired gynatresia were birth injuries (6 patients, 15.4%), and female genital mutilation (2, 5.1%). CONCLUSION: Acquired gynatresia was more common in Lagos than congenital gynatresia. The causes of acquired gynatresia are preventable and could be eliminated by health education.

Anatomic variations in the palmar cutaneous branch of the median nerve among adults in Lagos, Nigeria.

UNLABELLED: Dysesthesias due to palmar cutaneous branch of median nerve injuries infrequently follow carpal tunnel release surgeries. OBJECTIVE: To determine the course of palmar cutaneous branch of the median nerve in wrist of adult Nigerians, identify the common variations, determine its relations to the palmaris longus (PL) in the region of the distal wrist crease. And on these basis, suggest a safe incision for carpal tunnel surgery in Nigerians. MATERIALS AND METHODS: Detailed anatomic dissection of the palmar cutaneous branch of the median nerve was carried out with the aid of a loupe magnification on 40 Nigerian cadaver wrists. The origin, course in the distal forearm, wrist and proximal palm was traced. Measurements of the distances between the radial and ulnar branches of the nerve and the PL were made. The distance between origin of the nerve and the distal wrist crease was measured as well. The common branching pattern of the nerve was noted. RESULTS: The palmar cutaneous branch of the median nerve was present in all dissected wrists. The mean distance of the radial branch to PL was 0.81 cm (SD ± 0.3 cm), while the ulnar branch was 0.3 cm (SD ± 0.1 cm). from same structure. The mean distance from the origin to the distal wrist crease is 4.5 cm (SD ± 2.1 cm). We noted the terminal distal branching pattern of the nerve to be highly variable. CONCLUSION: The Palmar cutaneous branch of the median nerve is safe with an incision made at least 0.5 cm ulnar to the PL in carpal tunnel surgeries in Nigerians.

Pudendal thigh flap in the treatment of acquired gynatresia from caustic pessaries.

OBJECTIVES: To evaluate the use of vaginoplasty with the pudendal thigh flap in patients with gynatresia caused by herbal pessaries in a multidisciplinary context. METHODS: The study included patients with herbal-pessary-induced vaginitis and gynatresia. Surgical treatment consisted of vaginoplasty with the pudendal thigh flap; patients with associated fibroids had a myomectomy during the same setting. The severity of the stenosis and the outcome after surgery were assessed with rating scales devised for the present study. RESULTS: The study included 21 patients (mean age 36.05 ± 1.69 years, range 18-50 years). The most common reason for herbal pessary use was fibroids with infertility. Prior to presentation, most patients had already undergone a median of 2 procedures involving vaginal adhesiolysis and dilatations without improvement. In total, 17 (80.9%) patients underwent surgery. Of these, 6 (35.3%) presented with both fibroids and gynatresia. Before surgery, all patients had poor sexual function with apareunia. Postoperatively, 11 (64.7%) patients reported painless sexual intercourse. CONCLUSION: Joint management by plastic surgeons and gynecologists using the pudendal thigh flap for vaginoplasty in caustic gynatresia resulted in a functional vagina. Simultaneous myomectomy and vaginoplasty in patients with fibroids and gynatresia was safe.

Blood transfusion requirements in cleft lip surgery.

OBJECTIVE: Cleft lip surgery is a common procedure performed by surgeons worldwide. The aim of the study was to determine blood transfusion requirements and factors influencing blood transfusion in cleft lip surgery. METHODS: Transfusion rate in 100 consecutive patients who had cleft lip surgery was prospectively evaluated at the Lagos University Teaching Hospital, Nigeria. Data collected included age and sex of patients, type of cleft defects, type of surgery done, preoperative haematocrit, duration of surgery, amount of blood loss during surgery, the number of units of blood cross-matched and those used. Cardiovascular parameters at the point of transfusion were also recorded. Each patient was made to donate a unit of homologous blood prior to surgery. RESULTS: Mean estimated blood loss during surgery was 26.5 ± 47.1 ml. Most patients (92%) lost between 2 and 50 ml of blood. Mean estimated blood loss in unilateral cleft lip surgery was not significantly differently from that of bilateral cleft lip surgery (P=0.46). Only five patients (5%) required blood transfusion. The mean blood transfused was 50.0 ± 16.9 ml. All the patients transfused had a preoperative haematocrit of <30% (23-27%). The cross-match-to-transfusion ratio for cleft surgery was 20. The transfusion index was 0.05 and overall blood-ordering quotient was 20. CONCLUSION: Cleft lip surgery is a low volume blood loss surgery. Homologous blood donation prior to cleft lip surgery in patients with preoperative haematocrit of 30% or more is not necessary. For patients with preoperative haematocrit of less than 30%, type and screen of donated blood should be adequate.

Frequency of homologous blood transfusion in patients undergoing cleft lip and palate surgery.

AIM: The study aims to determine the frequency of homologous blood transfusion in patientsundergoing cleft lip and palate surgery at the Lagos University Teaching Hospital, Nigeria. SETTING AND DESIGN: A prospective study of transfusion rate in cleft surgery conducted at the Lagos University Teaching Hospital, Nigeria. MATERIAL AND METHODS: One hundred consecutive patients who required cleft lip and palate surgery were recruited into the study. Data collected included age, sex and weight of patients, type of cleft defects, type of surgery done, preoperative haematocrit, duration of surgery, amount of blood loss during surgery, the number of units of blood cross-matched and those used. Each patient was made to donate a unit of homologous blood prior to surgery. RESULTS: There were 52 females and 48 males with a mean age of 64.4 ± 101.1 months (range, 3-420 months). The most common cleft defect was isolated cleft palate (45%) followed by unilateral cleft lip (28%). Cleft palate repair was the most common procedure (45%) followed by unilateral cleft lip repair (41%). The mean estimated blood loss was 95.8 ± 144.9 ml (range, 2-800ml). Ten (10%) patients (CL=2; CP=5, BCL=1; CLP=2) were transfused but only two of these were deemed appropriate based on percentage blood volume loss. The mean blood transfused was 131.5 ± 135.4ml (range, 35-500ml). Six (60%) of those transfused had a preoperative PCV of < 30%. Only 4.9% of patients who had unilateral cleft lip surgery were transfused as compared with 50% for CLP surgery, 11% for CP surgery, and 10% for bilateral cleft lip surgery. CONCLUSIONS: The frequency of blood transfusion in cleft lip and palate surgery was 10% with a cross-match: transfusion ratio of 10 and transfusion index of 0.1. A "type and screen" policy is advocated for cleft lip and palate surgery.

Cleft deformities in adults and children aged over six years in Nigeria: Reasons for late presentation and management challenges.

In developing countries, untreated cleft lips and palates are found with increasing frequency and patients often present to the surgeon far past the optimal time for closure of the cleft deformities. A prospective study was conducted between March 2007 and September 2009, to identify the reasons and treatment challenges of delayed presentation of cleft lip and palate deformities at the Lagos University Teaching Hospital, Nigeria. Out of a total of 150 patients with cleft defects during the period, 43 (28.7%) were adults and children aged over six years. The mean age of these patients at the time of presentation was 17.3 years. The most common reasons for late presentation were lack of money (56.7%), lack of health care services nearby (18.4%), and lack of awareness of treatment availability (13.3%). Common challenges in these patients included surgical, orthodontic, speech, anesthetic, and psychological. Although adult clefts were significantly enlarged in three dimensions the anatomic landmarks were easier to discern than in an infant. However, extensive soft tissue dissection in adult cleft lip repair resulted in significant postoperative edema. Closure of wide palatal cleft often required the use of adjunct intraoral flaps. Despite late presentation, surgical outcome of these patients was satisfactory and comparable to cleft repair in infants.

Keloid and hypertrophic scars: a review of recent developments in pathogenesis and management.

AIM: The treatment of keloid and hypertrophic scars remains a challenging clinical problem despite numerous proposed therapies reported in the literature. This is due to the fact that the mechanisms that bring about keloid/hypertrophic scars are not completely understood. This article reviews the pertinent literature regarding the pathophysiology and management of keloid and hypertrophic scars. MATERIAL AND METHODS: A computerized literature search using MEDLINE was conducted for published articles on keloid and hypertrophic scars. The medical subject headings "keloid" or "hypertrophic scar" were combined with "treatment" or "management" or "mechanisms" or "pathophysiology" using the Boolean operator "AND" to narrow the searches. A review of selected relevant literature was undertaken. RESULTS: Numerous advances have been made in understanding the process of formation of wound healing and scar formation. This increased knowledge has led to the introduction of new treatments as well as to a better understanding of how older treatments work. These include surgical excision, intralesional steroid injection, cryotherapy, laser therapy, irradiation, mechanical compression dressing, silicone sheet applications, intralesional interferon injection, or combination of techniques. Many of the treatment modalities have a defined biologic basis while others are based on anecdotal reports. CONCLUSIONS: Presently there is still no single, reliable and effective treatment protocol for keloid and hypertrophic scars. However, surgical excision followed by postoperative intralesional steroid injection seems to provide a reasonable treatment outcome with low recurrence rate.
