Comparison of Doxycycline, Minocycline, Doxycycline plus Albendazole and Albendazole Alone in Their Efficacy against Onchocerciasis in a Randomized, Open-Label, Pilot Trial
2017
The search for new macrofilaricidal drugs against onchocerciasis that can be administered in shorter regimens than required for doxycycline (DOX, 200mg/d given for 4-6 weeks), identified minocycline (MIN) with superior efficacy to DOX. Further reduction in the treatment regimen may be achieved with co-administration with standard anti-filarial drugs. Therefore a randomized, open-label, pilot trial was carried out in an area in Ghana endemic for onchocerciasis, comprising 5 different regimens: the standard regimen DOX 200mg/d for 4 weeks (DOX 4w, N = 33), the experimental regimens MIN 200mg/d for 3 weeks (MIN 3w; N = 30), DOX 200mg/d for 3 weeks plus albendazole (ALB) 800mg/d for 3 days (DOX 3w + ALB 3d, N = 32), DOX 200mg/d for 3 weeks (DOX 3w, N = 31) and ALB 800mg for 3 days (ALB 3d, N = 30). Out of 158 randomized participants, 116 (74.4%) were present for the follow-up at 6 months of whom 99 participants (63.5%) followed the treatment per protocol and underwent surgery. Histological analysis of the adult worms in the extirpated nodules revealed absence of Wolbachia in 98.8% (DOX 4w), 81.4% (DOX 3w + ALB 3d), 72.7% (MIN 3w), 64.1% (DOX 3w) and 35.2% (ALB 3d) of the female worms. All 4 treatment regimens showed superiority to ALB 3d (p < 0.001, p < 0.001, p = 0.002, p = 0.008, respectively), which was confirmed by real-time PCR. Additionally, DOX 4w showed superiority to all other treatment arms. Furthermore DOX 4w and DOX 3w + ALB 3d showed a higher amount of female worms with degenerated embryogenesis compared to ALB 3d (p = 0.028, p = 0.042, respectively). These results confirm earlier studies that DOX 4w is sufficient for Wolbachia depletion and the desired parasitological effects. The data further suggest that there is an additive effect of ALB (3 days) on top of that of DOX alone, and that MIN shows a trend for stronger potency than DOX. These latter two results are preliminary and need confirmation in a fully randomized controlled phase 2 trial.

Anti-Bacterial Agents - therapeutic use
2008
In a randomized, placebo-controlled trial in Ghana, 67 onchocerciasis patients received 200-mg/day doxycycline for 4–6 weeks, followed by ivermectin (IVM) after 6 months. After 6–27 months, efficacy was evaluated by onchocercoma histology, PCR and microfilariae determination. Administration of doxycycline resulted in endobacteria depletion and female worm sterilization. The 6-week treatment was macrofilaricidal, with >60% of the female worms found dead, despite the presence of new,
Wolbachia
-containing worms acquired after the administration of doxycycline. Doxycycline may be developed as second-line drug for onchocerciasis, to be administered in areas without transmission, in foci with IVM resistance and in areas with
Loa
co-infections.

Background
Musculoskeletal disease is a growing burden in low- and middle-income countries (LMICs), yet little research exists to describe the problem. The purposes of this study were to characterize orthopedic surgery in an LMIC and compare the findings to those from a developed country.
Methods
The study location was the Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana. Orthopedic surgeon, resident, and postgraduate training program numbers were compared to analogous data from a developed nation, the United States. Annual surgical volumes were compared to those at a level I trauma center in the United States, the San Francisco General Hospital (SFGH).
Results
There were 24 surgeons in Ghana compared to 23,956 in the United States. There were 7 orthopedic residents and 1 residency program in Ghana versus 3,371 residents and 155 residencies in the United States. Annual case volume was 2,161 at KATH and 2,132 at SFGH. Trauma accounted for 95 % of operations at KATH compared to 65 % at SFGH. The proportion of surgeries devoted to severe fractures was 29 % at KATH compared to 12 % at SFGH. Infections comprised 15 % of procedures at KATH and 5 % at SFGH.
Conclusions
Annual case volume at a referral hospital in an LMIC is equivalent to that of a level I trauma center in an industrialized country. Total case volume is similar, but the LMIC institution manages a disproportionately large number of trauma cases, severe fractures, and infections. There is a large burden of orthopedic disease in the developing nation, and there are too few providers and training programs to address these conditions.

Cleft hands and monodactylous feet: A rare variant of ectrodactyly
2016
A 2-year-old male child presented with bilateral asymmetric cleft hands, a right monodactylous foot (diastatic type), posteriorly dislocated at the ankle joint, and a left monodactylous foot (Type VI, Blauth and Borisch) posteriorly dislocated at the ankle joint. Surgical management has enabled weight bearing and walking. Psychological problems, especially with the hands, are anticipated. Further multidisciplinary management by surgeons, physical therapists, clinical psychologists, child psychologists, and occupational therapists is advocated.

Background
In high- and middle-income countries, elastic stable intramedullary nailing (ESIN) is the commonest treatment of femur fractures in children 5–11 years of age. At Komfo Anokye Teaching hospital (KATH) in Kumasi, Ghana, prior to this study all pediatric femur fractures were treated with skin traction to union. This study was designed to report the early results and costs of the adoption of ESIN at KATH to provide data to other low- and middle-income sites considering adoption of this surgical technique.
Methods
An observational cohort study that included 84 pediatric patients ages 3–14 years presenting with closed femur fractures and treated with either skin traction or ESIN. Multivariate logistic regression was used to compare the rate of treatment success between treatment groups.
Results
Treatment success (coronal and sagittal angulation less than 10 ° and shortening less than 15 mm at osseous union) was achieved in 92 % of the ESIN group versus 67 % of the skin traction group (odds ratio for ESIN group 9.28 (1.6–54.7);
p
= 0.0138). Average length of stay was significantly lower in the ESIN group (
p
= 0.001), but charges to patients were higher in the ESIN group (
p
< 0.001) because of the high cost of implants.
Conclusions
The initial experience of operative treatment of femoral shaft fractures in children using ESIN was positive, with improved rates of treatment success and no surgical complications. Because of the high cost of implants, direct costs of treatment remained higher with ESIN despite reductions in length of hospital stay.

Objective
To determine the rate of preventable trauma deaths in an African hospital, identify the potential effect of improvements in trauma care over the past decade and identify deficiencies in care that still need to be addressed.
Methods
A multidisciplinary panel assessed pre-hospital, hospital, and postmortem data on 89 consecutive in-hospital trauma deaths over 5 months in 2017 at the Komfo Anokye Teaching Hospital. The panel judged the preventability of each death. For definitely and potentially preventable deaths, the panel identified deficiencies in care.
Results
Thirteen percent (13%) of trauma deaths were definitely preventable, 47% potentially preventable, and 39% non-preventable. In comparison with a panel review in 2007, there was no change in total preventable deaths, but there had been a modest decrease in definitely preventable deaths (25% in 2007 to 13% in 2017,
p
= 0.07) There was a notable change in the pattern of deficiency (
p
= 0.001) with decreases in pre-hospital delay (19% of all trauma deaths in 2007 to 3% in 2017) and inadequate resuscitation (17 to 8%), but an increase in delay in treatment at the hospital (23 to 40%).
Conclusions
Over the past decade, there have been improvements in pre-hospital transport and in-hospital resuscitation. However, the preventable death rate remains unacceptably high and there are still deficiencies to address. This study also demonstrates that preventable death panel reviews are a feasible method of trauma quality improvement in the low- and middle-income country setting.
