Campylobacter diarrhea in children in South Asia: A systematic review

BackgroundCampylobacter spp. are one of the commonest causes of diarrhea in children under five and in resource poor settings also lead to malabsorption and stunting. The purpose of this systematic review was to understand the burden of Campylobacter spp. associated diarrhea among children in the South Asian countries.MethodsThis systematic review followed the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analysis) guidelines. Databases were searched with defined keywords for publications from the years 1998–2018. Data on proportion of positive samples was extracted to compare the rates of Campylobacter infection among children (under the age of 19) from different study populations.ResultsOf the 359 publications screened, 27 eligible articles were included in this systematic review and categorized based on study design. In 8 case-control studies, Campylobacter spp. was detected more frequently among diarrheal cases (range, 3.2–17.4%) than non-diarrheal cases (0–13%). Although there were variations in the study population, overall, children under the age of two years experienced Campylobacter diarrhea more often than older children. Most studies reported stool culture as the method used to detect Campylobacter spp. however retesting using PCR-based methods significantly increased detection rates. Limited data were available on Campylobacter species. In 4 studies that provided species data, C. jejuni (3.2–11.2%) was shown to be the most common species, followed by C. coli.ConclusionIn South Asia, Campylobacter spp. are one of the most common bacterial diarrheal pathogens affecting children but there is a paucity of data on species, risk factors and attributable sources. Although a few studies were available, the epidemiology of campylobacteriosis remains uncertain. To understand the true burden and sources of infection, more detailed studies are needed collecting data from human, animal and environmental sources and using both culture and genomic tools.     

Dorsal suspension for Morton’s neuroma: A comparison with neurectomy

BackgroundThe purpose of this study was to investigate and compare the clinical outcomes of dorsal suspension with those of neurectomy for the treatment of Morton’s neuroma.MethodsWe conducted a retrospective study of dorsal suspension and neurectomy group. The dorsal suspension was performed by dorsal transposition of neuroma over the dorsal transverse ligament after neurolysis. The visual analog scale (VAS), the Foot and Ankle Ability Measure (FAAM), postoperative satisfaction, and complications were evaluated.ResultsBoth groups reported significant pain relief, and there were no significant differences between the groups with respect to postoperative pain. The postoperative FAAM outcomes showed no significant between-group differences. Satisfaction analysis showed ‘excellent’ and ‘good’ results in the dorsal suspension and neurectomy groups (95% and 77.7%, respectively). Complications of numbness and paresthesia reported in the dorsal suspension group (5% and 5%, respectively) were significantly fewer than those of neurectomy group (61.1% and 33.3%, respectively) (both, p < .05).ConclusionsWith its favorable results, dorsal suspension can be another operative option for the treatment of Morton’s neuroma.Level of Evidence: Level III, retrospective comparative case series.     

Risk Factors for Pressure Sores in Hospitalized Acute Ischemic Stroke Patients

BackgroundAcute ischemic stroke patients are a group at high risk for pressure sores. It is important to identify risk factors for pressure sores in acute ischemic stroke patients in order to facilitate early adoption of appropriate preventive and treatment measures.MethodsData were derived from the China National Stroke Registry. Acute ischemic stroke patients aged >18 years who presented at the hospital within 14 days after the onset of symptoms were eligible for this study. Comprehensive baseline data were collected. The definition of pressure sores was based on assessment at discharge of whether the patient had pressure sores at any time during hospitalization.Results12,415 patients with a mean age of 67 years and a mean length of hospitalization of 14 days were included in the study. Among these patients, 97 (0.8%) had pressure sores during hospitalization. In the multivariate analysis of risk factors for pressure sores, age (each increment of 5 years), being unmarried, NIHSS at admission (each increment of 3 points), mRS at admission (3-5 points), diabetes mellitus, hemoglobin at admission (each incremental reduction of 10 units), and history of peripheral vascular disease all were significantly correlated with the occurrence of pressure sores among acute ischemic stroke patients during hospitalization.ConclusionsOld age, severe neurological disability, being unmarried, low hemoglobin, and history of diabetes mellitus and peripheral vascular disease were risk factors for pressure sores in acute ischemic stroke patients.     

Vancouver B2 Peri-Prosthetic Fractures in Cemented Femoral Implants can be Treated With Open Reduction and Internal Fixation Alone Without Revision

BackgroundThe aim of this study is to assess the outcomes of 52 consecutive Vancouver B2 peri-prosthetic fractures around cemented polished double-tapered stems treated by open reduction and internal fixation in 2 trauma centers in 2 countries.MethodsOutcomes included modified Harris Hip Score (mHHS), Harris Pain Score, and return to pre-injury mobility. Fracture healing was assessed; implant subsidence measured and complications including re-operations reported.ResultsNo patient was lost to follow-up. Median patient age at operation was 82 years (range 43-98); Harris pain scores showed minimal pain (median 42, range 10-44) at latest follow-up. Median total subsidence at 1 year was 1.1 mm (range 0-5.4), the majority of which occurred within the cement mantle. No subsequent femoral stem revision was required (median 2.9 years, 0-10); however, there were 3 re-operations: 1 re-operation for pre-existing recurrent dislocation involving head liner exchange and 2 for repeat fixation due to metal fatigue. Two additional fractures occurred below the new plating, requiring further plating whilst still retaining the original stems.ConclusionAnatomical reduction and open reduction and internal fixation of Vancouver B2 peri-prosthetic fractures should be considered as an appropriate treatment solution for frail elderly patients with a peri-prosthetic fracture around cemented polished double-tapered stems.     

Xenotransplantation in Asia

The organ shortage crisis affects most of the world today. In Asia, rates of deceased organ donation are extremely low due to sociocultural factors. In this context, implementing new organ donation policies is not enough; xenotransplantation remains the most promising way to solve the organ crisis. Most of the early research on xenotransplantation was conducted in the US and Europe. Today, however, Asia has caught up on its Western counterparts partly due to the increasing demand for organ transplants. Given the growing influence of countries such as China, South Korea, and Japan in xenotransplantation, this article provides the reader with an essential global understanding of the scientific and ethical issues currently at stake. Furthermore, it sheds light on the beliefs and values that shape the response of the Asian public to both organ donation and xenotransplantation.
