The Effect of Prolonged Pre-Operative Halo Gravity Traction for Severe Spinal Deformities on the Cervical Spine Radiographs.

STUDY DESIGN: Retrospective review of consecutive series. OBJECTIVE: The study sought to assess the effect of prolonged pre-operative halo gravity traction (HGT) on the c-spine radiographs. METHODS: Data of 37 pediatric and adult patients who underwent ≥ 12wks pre-op HGT prior to definitive spine surgery from 2013-2015 at a single site in West Africa was reviewed. Radiographic assessment of the c-spine including ADI, SVA and C2-C7 Lordosis were done at pre HGT and at 4 weekly intervals. Paired T-Test was performed to evaluate changes in these parameters during HGT. RESULTS: 37pts, 18/19 (F/M). Average age 18.2yrs. Diagnoses: 22 idiopathic, 6 congenital, 3 Post TB, 2 NM and 4 NF. Average duration of HGT: 125 days. Baseline coronal Cobb:130 deg, corrected 30% in HGT; baseline sagittal Cobb:146 deg, corrected 32% post HGT. Baseline ADI (3.17 ± 0.63 mm) did not change at 4wks (P > 0.05) but reduced at 8wks (2.80 ± 0.56 mm) and 12wks (2.67 ± 0.51 mm) post HGT (P < 0.05). Baseline HGT SVA (20.7 ± 14.98 mm) significantly improved at 4wks (11.55 ± 10.26 mm), 8wks (7.54 ± 6.78 mm) and 12wks (8.88 ± 4.5 mm) (P < 0.05). Baseline C2-C7 lordosis (43 ± 20.1 deg) reduced at 4wks (26 ± 16.37 deg), 8wks (17.8 ± 14.77 deg) and 12wks (16.7 ± 11.33 deg) post HGT (P < 0.05). There was no incidence of atlanto-axial instability on flexion extension radiographs at any interval. CONCLUSION: Prolonged HGT, while providing partial correction of severe spine deformities, also appeared to have no adverse effect on atlanto-axial stability or cervical alignment. Therefore, HGT can be safely applied for several weeks in the preoperative management of severe spine deformities in pediatric/adult patients.

Surgical management of complex post-tuberculous kyphosis among African patients: clinical and radiographic outcomes for a consecutive series treated at a single institution in West Africa.

STUDY DESIGN: Retrospective review of consecutive series. OBJECTIVE: To assess the clinical and radiographic outcomes after surgical management of post-tuberculous kyphosis. Post-tuberculous (TB) kyphosis can lead to progressive pulmonary and neurological deterioration. Surgery is indicated to decompress neural elements and correct the spine deformity. Although posterior vertebral column resection (PVCR) has been established as the treatment of choice for severe TB kyphosis, there is paucity of studies on the clinical outcomes among patients treated in West Africa. METHODS: Clinical and radiographic data of 57 patients (pts) who underwent surgical correction of post-TB kyphosis at a single site in West Africa between 2013 and 2018 (≥ 2-year follow-up in 36 pts, ≥ 1-year FU in 21 pts). Pre- and post-op SRS scores and radiographic outcomes were compared using Paired t test. RESULTS: 57 patients, 36M:21F. Mean age 19 (11-57 years). 22/57 pts (39.3%) underwent pre-op halo gravity traction (HGT) for an average duration of 86 days (8-144 days). HGT pts had a higher baseline regional kyphosis (125.1 ± 20.9) compared to non-HGT pts (64.6 ± 31.8, p < 0.001). Post-HGT regional kyphosis corrected to 101.2 ± 23 (24° correction). 53 pts (92.9%) underwent posterior-only surgery and 4 (7.0%) combined anterior-posterior surgery. 39 (68.4%) had PVCR, 11 (19.3%) PSO, and 16 (28.1%) thoracoplasty. Intraoperative neuromonitoring (IOM) signal changes occurred in 23/57 pts (≈ 40%), dural tear in 5 pts (8.8%), pleural tear in 3 pts (5.3%), ureteric injury in 1 pt (1.7%), and vascular injury in 1 pt (1.7%). Post-op complications included four (7.0%) infection, three (5.3%) implant related, two (3.5%) radiographic (one PJK and one DJK), one (1.7%) neurologic, one (1.7%) wound problem, and two (3.5%) sacral ulcers. IOM changes were similar in the VCR (48.7%) and non-VCR (23.5%) pts, p > 0.05. Complication rates were similar among HGT and non-HGT groups. Significant improvements from baseline were seen in the average SRS Total and domains scores and radiographic measurements for patients who attained 2-year follow-up. CONCLUSION: PVCR ± HGT can provide safe and optimal correction in cases of severe post-TB kyphosis with good clinical and radiographic outcomes in underserved regions.

Postoperative Pulmonary Complications in Complex Pediatric and Adult Spine Deformity: A Retrospective Review of Consecutive Patients Treated at a Single Site in West Africa.

STUDY DESIGN: Retrospective review of consecutive series. OBJECTIVES: This study sought to assess the incidence, risk factors, and outcomes of pulmonary complication following complex spine deformity surgery in a low-resourced setting in West Africa. METHODS: Data of 276 complex spine deformity patients aged 3 to 25 years who were treated consecutively was retrospectively reviewed. Patients were categorized into 2 groups during data analysis based on pulmonary complication status: group 1: yes versus group 2: no. Comparative descriptive and inferential analysis were performed to compare the 2 groups. RESULTS: The incidence of pulmonary complication was 17/276 (6.1%) in group 1. A total of 259 patients had no events (group 2). There were 8 males and 9 females in group 1 versus 100 males and 159 females in group 2. Body mass index was similar in both groups (17.2 vs 18.4 kg/m2, P = .15). Average values (group 1 vs group 2, respectively) were as follows: preoperative sagittal Cobb angle (90.6° vs 88.7°, P = .87.), coronal Cobb angle (95° vs 88.5°, P = .43), preoperative forced vital capacity (45.3% vs 62.0%, P = .02), preoperative FEV1 (forced expiratory volume in 1 second) (41.9% vs 63.1%, P < .001). Estimated blood loss, operating room time, and surgery levels were similar in both groups. Thoracoplasty and spinal osteotomies were performed at similar rates in both groups, except for Smith-Peterson osteotomy. Multivariate logistic regression showed that every unit increase in preoperative FEV1 (%) decreases the odds of pulmonary complication by 9% (OR = 0.91, 95% CI 0.84-0.98, P = .013). CONCLUSION: The observed 6.1% incidence of pulmonary complications is comparable to reported series. Preoperative FEV1 was an independent predictor of pulmonary complications. The observed case fatality rate following pulmonary complications (17%) highlights the complexity of cases in underserved regions and the need for thorough preoperative evaluation to identify high-risk patients.

A cross-sectional self-assessment of burnout amongst a sample of doctors in Ghana.

BACKGROUND: The occurrence of burnout amongst African health professionals has been widely anticipated, but there is a dearth of published data, especially amongst doctors. Burnout has been reported to be as high as 53% amongst doctors in the United States. If not detected, it can result in prescription errors, work-related accidents, substance abuse and depression. AIM: The aim of this study was to determine the prevalence of burnout and its associated factors amongst a sample of physicians in Ghana. SETTING: This study was conducted in Kumasi amongst physicians attending a conference organised by the West African College of Physicians, Ghana Chapter. METHOD: A cross-sectional study. Of the 90 physicians who registered for the conference, 60 responded to a self-administered Maslach Burnout Inventory questionnaire. Data were analysed descriptively and inferentially using STATA® version 14. RESULTS: Approximately 52% of respondents had been in medical practice for 10-19 years (mean 15.4 years). All the major medical specialties were represented. Internal Medicine had the highest number of participants (48.3%). With respect to the components of burnout, 5.5% of respondents experienced depersonalisation, 7.8% had a lack of personal achievement and 10.8% experienced emotional exhaustion. The association between burnout and age, sex, years of practice and clinical specialty was not found to be statistically significant. CONCLUSION: This pilot study has shown burnout to be common amongst physicians in Ghana. It is recommended that further studies are conducted, involving a larger cross-section of doctors in various parts of Africa.

Malaria chemoprophylaxis: cross-sectional study of use among air travellers departing from Accra, Ghana.

Background: Malaria is the most common life-threatening infectious disease among travellers and chemoprophylaxis is recommended. The overall effectiveness, medication types and cost of malaria chemoprophylaxis in Accra are not well documented. This study investigated the use of chemoprophylaxis for malaria prevention in air travellers departing from Kotoka International Airport (KIA) in Accra, Ghana. Materials and methods: A cross-sectional study was conducted in the departure lounge of the KIA between February and May 2012. A total of 424 respondents voluntarily completed a semi-structured questionnaire, which included socio-demographic characteristics, duration of stay, nationality, country of permanent residence, chemoprophylaxis used, number of doses missed, cost and side effects experienced, and cost of treatment. Results: The mean age of respondents was 37 ± 0.84 years with a male:female ratio of 1.2:1.The mean duration of stay in Ghana was 47.9 days [SD 56.8] and 73.5% had made one trip to the country in the preceding year. Of the respondents, 50.7% were from Europe, 24.1% from North America and 17.5% from Africa. The most popular malaria prevention method used was prophylactics (37%) with atovaquone/proguanil used most frequently (34.9%), followed by mefloquine (11.6%) and doxycycline (7.8%). Compliance was high: 73.8% of respondents did not miss a single dose. The most commonly reported side effects were dreams, abdominal discomfort and headaches. Malaria incidence was 7.1% with 80% of them receiving treatment in a hospital or clinic; incurring a cost of up to $30 to treat a person. Conclusions: Most air travellers from Accr a take atovaquone/pr oguanil. Malaria incidence was low and most travellers were compliant with their chemoprophylaxis with very few side effects. The cost of chemoprophylaxis is low and is thus recommended for all travellers to Accra, Ghana.
