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.

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.

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.

Microvascular Anastomosis of Vessels Less Than 0.5 mm in Diameter: A Supermicrosurgery Training Model in Lagos, Nigeria.

The development of reconstructive microsurgery has now reached the supermicrosurgery stage. However the anastomosis of vessels under 0.5 mm is still out of the comfort zone of the many microsurgeons. To confirm the technical feasibility and the reliability of this technique We relate our own experience in this regard using the free superficial inferior epigastric flap of the rat as a model for supermicrosurgery training at the Microsurgery Laboratory of the Lagos University teaching hospital. 18 of the 20 free flaps transferred survived at 1 week. Two flaps necrosed and two flaps dehisced. We believe based on our work that the average microsurgeon can become comfortable working with these vessels.

Macrostomia: a study of 15 patients seen in Lagos, Nigeria and proposal for a classification of severity.

We made a descriptive epidemiological study of patients who presented with isolated macrostomia during a mass screening programme and repair of orofacial cleft deformities in Lagos, Nigeria. Detailed histories of environmental, gestational, and hereditary factors that may contribute to the malformation were taken, and physical examinations and specialist consultations to detect associated congenital malformations were made. Three patients had unilateral macrostomia and in 12 it was bilateral and symmetrical. The mean (SD) age was 8 (2) years, range 3 months to 32 years. There were 6 men and 9 women. Two women and one man had unilateral macrostomia; the two women presented with right sided involvement, while the man had left sided involvement. The commonest associated malformation was a low-set ear (n = 7). Other patients had combinations of congenital malformations. The mean (SD) age of the mothers at conception was 24 (1) years, range 18 to 32 years, while those of the fathers during the periods of conception were 35 (1) years, range 26 to 45. No gestational or environmental factors were detected in the history. One mother with unilateral presentation had a child with bilateral deformities.
