Outbreak of Arcanobacterium haemolyticum in chronic wounds in The Netherlands.

INTRODUCTION: Aging and comorbidities such as diabetes and vascular problems contribute to the increasing occurrence of chronic wounds. From the beginning of 2016, a marked increase in Arcanobacterium haemolyticum (ARH) in chronic wound cultures was noted among patients visiting a wound expertise centre in The Netherlands. AIM: To report the outbreak investigation of ARH cultured from chronic wounds and describe the implemented infection prevention measures. METHODS: In total, 50 ARH isolates were sent to a reference laboratory for molecular typing. Samples for bacterial culture and ARH polymerase chain reaction were taken from care workers, the environment and items used for wound care. Infection prevention measures were implemented in a bundled approach, involving education, better aseptic wound care conditions and hygienic precautions. Before and after the implementation of infection prevention measures, two screening rounds of ARH testing were performed among all patients receiving home care. RESULTS: ARH isolates from wound care patients were found to be identical by core genome multi-locus sequence typing. No definite outbreak source could be determined by culture. However, three pairs of forceps, used by two nurses on multiple patients, were found to be ARH positive by polymerase chain reaction. In the two screening rounds before and after the implementation of infection prevention measures, the proportion of ARH-positive patients decreased significantly from 20% (20/99) to 3% (3/104). Subsequently, no new cases occurred. CONCLUSION: This first ARH outbreak was likely caused by re-using contaminated instruments. Through the implementation of improved infection prevention measures and re-education of all employees involved, the outbreak was controlled. With the current trend of care transition, infection control must be a major concern.

Use of autologous platelet-rich fibrin on hard-to-heal wounds.

This retrospective study found that use of autologous platelet-rich fibrin on a range of hard-to-heal wounds achieved full healing or a significant reduction in wound diameter with no adverse effects. Prospective studies are now needed

Extracellular matrix prevents split-skin grafting in selected cases.

Surgeons at a Dutch wound clinic close open wounds with split-skin grafts. Concerns about the risk of postoperative complications in some patients led them to find an alternative option. Use of an extracellular matrix dressing was effective.

Determining pain levels in patients treated with maggot debridement therapy.

OBJECTIVE: Pain as a complication of maggot debridement therapy (MDT) has been a topic of some controversy. This study set out to determine pain levels in patients treated with MDT. METHOD: A retrospective analysis using a visual analogue scale (VAS) was performed: 41 patients were treated with MDT for non-healing wounds (22 men and 19 women; average age: 67 years). Average wound duration was 14 months (range: two weeks to 132 months). Maggots were applied using the contained or the free-range techniques. Paracetamol (1 g three times daily) and Durogesic plaster (25 microg every three days and 50 microg the day before the maggot change) were given for pain relief in the outpatient clinic. RESULTS: Diabetic patients experienced the same amount of pain before and during MDT. Eight out of 20 non-diabetic patients experienced more pain during MDT than before; the remaining non-diabetic patients had the same amount of pain before and during the therapy. The difference between diabetic and non-diabetic patients was statistically significant (p<0.05) for all applications combined. CONCLUSION: In 78% of patients (29/37) pain can be adequately treated with analgesic therapy. However, if pain is unmanageable in the outpatient department, we believe that options include hospital admission, using the contained method of application or, in the worst case scenario, cessation of treatment. A standardised but individually tailored pain management protocol is mandatory.

Use of larval therapy to combat infection after breast-conserving surgery.

Wound infection after breast surgery is not uncommon and is not always simple to treat. This paper presents the case of a patient in whom the wound was successfully treated with larval debridement therapy after other methods failed.

External fixation for unstable intra-articular distal radial fractures in women older than 55 years. Acceptable functional end results in the majority of the patients despite significant secondary displacement.

UNLABELLED: Unstable intra-articular distal radial fractures in women older than 55 years were treated by closed reduction and external fixation to achieve the best functional outcome. Sixteen women had radiographic and functional assessment. Despite initial good alignment secondary displacement occurred in 11 patients, probably due to the comminution of the fracture and possibly influenced by osteoporosis. Malunion of the distal radius was seen in two patients and intra-articular incongruity with an intra-articular step exceeding 1 mm was observed in two other patients. The functional outcome was excellent or good in 10 and fair in two patients. Four patients had a poor functional outcome. Two of these patients had a significant loss of reduction, one resulting in a malunion. The other two had an intra-articular incongruity of more than 1 mm. Three of the four patients with a poor functional outcome had clinical signs of reflex sympathetic dystrophy. CONCLUSION: Closed reduction and external fixation of "bad case" severely comminuted unstable distal radial fractures in the elderly may result in an acceptable functional outcome in the majority of the cases, although significant secondary displacement occurred in eleven of the sixteen patients.

A 34-year-old man sought medical advice for a dog bite on his left lower leg. The wound progressed after split skin transplantation. It was proved to be pyoderma gangrenosum associated with colitis ulcerosa and responded well to oral prednisone therapy.

The distal radial fracture in elderly women and the bone mineral density of the lumbar spine and hip.

The incidence of distal radial fractures in elderly women is high and is associated with osteoporosis and hip fracture. Osteoporosis can be detected by measuring the bone mineral density (BMD) of the lumbar spine or hip with dual energy X-ray absorptiometry. Low BMD of the lumbar spine or hip is a strong predictor for future vertebral deformities and hip fractures. At present, elderly women with a distal radial fracture are not investigated for osteoporosis on a routine basis. The BMD of the lumbar spine and hip were assessed in 94 women (mean age, 69 years) with a distal radial fracture. A low BMD was found in 85% of the patients, and osteoporosis was diagnosed in 51%. The mean BMD decreased by 0.04 SD per year and there was a significant relationship between post-menopausal status and decreased BMD of the hip. The BMD in patients treated with bisphosphonate medication increased significantly in 1 year. As more than half of the elderly women with a distal radial fracture have osteoporotic BMD values for the lumbar spine or hip, it is our opinion that such patients should be screened for osteoporosis.

Combining topical negative pressure and a Bogota bag for managing a difficult laparostomy.

A patient with a severe intra-abdominal infection required a laparostomy. A Bogota bag was combined with topical negative pressure therapy, saving nursing time and enabling successful management of wound fluid.

Giant colonic diverticula. Review of diagnostic and therapeutic options.

BACKGROUND: A rare complication of diverticulosis of the colon is giant colonic diverticula (GCD). The condition was first described in English literature in 1953. METHODS: A Medline search was undertaken for English, French and German language articles on 'giant colonic diverticula'. RESULTS: A total of 135 patients were identified, presenting with a total of 155 GCD. With a complication rate of 28% and an operative mortality of 5%, GCD seems to have a high clinical significance. Radiological examination of choice seems to be plain abdominal X-ray and CT examination, barium enema carries the risk of perforation of the diverticulum, and should not be performed. CONCLUSIONS: There are different therapeutic options, in our opinion diverticulectomy alone is not the treatment of choice. Because of the possibility of recurrence and oncological reasons, colectomy seems to be the best treatment. The creation of a protecting colostomy depends on other operative findings.

Arthroscopically assisted osteosynthesis of tibial plateau fractures in patients older than 55 years.

PURPOSE: To evaluate the end results of arthroscopically assisted osteosynthesis of tibial plateau fractures in patients older than 55 years of age. TYPE OF STUDY: Case series. METHODS: Over a 5-year period, 201 consecutive patients presented with tibial plateau fracture; 131 of these patients were treated with arthroscopically assisted osteosynthesis of the tibial plateau. Inclusion in the retrospective analysis was limited to those patients older than 55 years at the time of injury and those who were available for follow-up at the time of the study. Thirty patients met these criteria. RESULTS: Secondary displacement occurred in 9 patients (30%) within 12 weeks after surgery. After a median follow-up of 3 years, 24 of 30 patients (80%) had an excellent or good clinical result according to the modified Rasmussen criteria. There was no difference in clinical outcome between the patients with or without secondary displacement of the fracture. CONCLUSIONS: Given the good clinical results, arthroscopically assisted osteosynthesis has been shown to be highly efficient in the treatment of tibial plateau fractures in the elderly.

Interrater reliability for the basic categories of the AO/ASIF's system as a frame of reference for classifying distal radial fractures.

This study is about agreement on the assignment into the three basic classes or categories (A, B, C) of the Arbeitsgemeinschaft für Osteosynthesefragen/Association for the Study of Internal Fixation's (AO/ASIF) classification system for distal radial fractures. A random sample of 124 distal radial fractures was classified by two experienced observers. Their agreement was calculated according to Cohen's kappa statistic. To investigate the possible bases for disagreement, all conflicting X-ray assessments were discussed in a consensus meeting. It appeared that the kappa value was .65 (good agreement) before the meeting; kappa rose to .86 (excellent agreement) after the consensus meeting. It appeared that the undisplaced fractures were a major source of disagreement. Further, the presence of articular involvement was an important issue. It was frequently noted that one observer classified the fracture as extraarticular (basic Class A), while the other observer chose classification as an intra-articular fracture (basic Class C) or vice versa. This phenomenon has been called the A/C reversal shift. It is concluded that radiological innovations might enhance agreement on articular involvement, and a separate category for undisplaced fractures should be defined in the Arbeitsgemeinschaft für Osteosynthesefragen (AO) system. However, agreement on relevant distinctive features and discussion of conflicting assessments may also be important in achieving excellent agreement.

Clinicians' recognition of 10 different types of distal radial fractures.

This study concerned baseline performance in recognition of 10 different types of distal radial fractures. Verbal tasks of admitting knowing about fractures and Visual tasks were designed for each fracture type. The Verbal task of admitting knowing consisted of a description with the relevant distinctive features of the fracture. The surgical resident was asked whether he admitted knowing the particular fracture described. The Visual task consisted of X-rays for which the subject had to label the fracture or identify its distinctive features. The test was presented to 30 surgical trainees working in five teaching hospitals. On the Verbal task of admitting knowing, scores were statistically significantly higher (68% "yes") than on the Visual task (33% correct). Responses met our criterion of 80% correct for the following fracture types: Colles's, distal forearm, and Smith's fracture. For seven other fracture types (combination radius and scaphoid, radial styloid process, dorsal Barton's, volar Barton's, pilon, chauffeur's, and lunate load fracture), the 80% criterion was not met. Analysis of the incorrect answers on the Visual task indicated that the surgical residents tended to label unknown fracture types as Colles's or Smith's fractures. Furthermore, the residents tended to overestimate their own diagnostic competence (overconfidence bias) for several fracture types. It was concluded that to improve diagnosis, the relevant distinctive features of distal radial fractures should be taught.

Fracture of the distal forearm: epidemiological developments in the period 1971-1995.

This study describes longterm epidemiological trends of 8361 distal forearm fractures out of 256,431 trauma patients (3 per cent) treated in a Dutch university hospital. The mean incidence rate across the whole lifespan was 42 per 10,000 inhabitants. The general picture was that the incidence rate decreased from 47 in 1971 to 38 per 10,000 in 1995. The highest age-specific incidence rate was found in the age group above 79 years (90 per 10,000), followed by the age group of 0-9 years (80 per 10,000). The pattern of aetiology did not change: the distribution was accidental fall (62 per cent), sports and leisure (19 per cent) and traffic (14 per cent). The rate of hospital admission increased from 6 per cent in 1971 to 14 per cent of patients in 1995. It appeared that the longterm increase of hospital admission can largely be attributed to patients younger than 50 years of age. It has been discussed that the rise in operative treatment may be explained by a growing population and a change in surgical policy leading to more indications to operate on distal forearm fractures.
