Imaging in osteomyelitis and Charcot neuroarthropathy: can infrared thermography aid in diagnosis?

Gillian Harkin

Differential diagnosis between active Charcot neuroarthropathy and infection in the presence of neuropathic ulceration presents a significant challenge to the clinician. Both conditions may present as a red, hot, swollen foot with an absence of pain. Although additional tests may aid in developing a clear diagnosis these can be invasive (blood testing), carry exposure to ionising radiation (X-ray) or be difficult to access rapidly (MRI). The following case study demonstrates how infrared thermography may prove useful within the clinical environment as a diagnostic test as well as a useful educational tool to guide treatment planning in collaboration with an individual with diabetes.

Article points

1. It can be difficult to differentiate between Charcot neuroarthropathy and osteomyelitis due to similar clinical presentations.

2. Thermal images can be used to inform discussions as part of realistic medicine

3. Thermal imaging may be helpful in identifying the origin of heat within the foot, aiding diagnosis.

Diabetic gastroparesis

      Gastroparesis is a recognised complication of diabetes (both type 1 and type 2) and, whilst not the most commonly observed complication, it carries with it a significant impact on a person’s health, glycaemic control, social functioning and mental wellbeing. Gastroparesis is often not well recognised because of the disparate group of symptoms it may present with. Symptoms are often misattributed or not recognised, and consequently the diagnosis is either missed or delayed. It should be managed by a multidisciplinary team with knowledge of and expertise in this area. Above all, the team should be understanding and help steer patients to the best supportive care.

Bilateral Charcot neuroarthropathy following successive surgical arterial revascularisation to both legs in a patient with diabetes — an interesting case history

Neil Baker and Isam Osman

An unusually good blood supply and peripheral neuropathy are reportedly accepted prerequisites for the pathogenesis of Charcot neuroarthropathy (CN) in people with diabetes. There is anecdotal evidence that CN does not occur in the presence of peripheral vascular disease. We report the first case of a person with diabetes who had revascularisation surgery performed to both legs independently, which was subsequently followed by CN in the corresponding feet. This case illustrates the importance of a good blood supply in the development of CN. Furthermore, it supports the concept that reduced arterial supply is protective against the development of CN. This case also highlights the need for regular follow-up reviews where postoperative hyperaemia is evident.

Article points

1. A very good blood flow is a prerequisite for active Charcot development

2. Although this is a rare case, it is advised to be vigilant in monitoring a hot, swollen, inflamed foot and leg after vascular intervention in a patient with existing neuropathy

3. Early detection and immobilisation (cast) of active Charcot with regular follow up is imperative to facilitate optimal resolution and reduction in deformity

4. Differential diagnosis is essential in the presentation of a neuropathic red/ discoloured (dark), hot, swollen foot and leg, particularly if ulceration is present.

Diabetes and menopause

Metabolic changes that occur during menopause are associated with increased incidence of type 2 diabetes and its risk factors, while menopausal symptoms have a negative effect on a person’s day-to-day life, and consequently their diabetes self-management. In women who are going through menopause, effective hormone replacement therapy (HRT) can improve a wide array of cardiometabolic risk factors as well as the risk of new-onset type 2 diabetes. This factsheet covers the relationship between menopause and type 2 diabetes and provides recommendations on optimising HRT in women with diabetes.

The impact of venous leg ulcers on a patient’s quality of life: considerations for dressing selection

Patients with venous leg ulcers (VLUs) experience a wide range of physical and psychosocial issues. This paper focuses on the impact of the sequelae of VLUs and the interventions that can be used to minimise that impact on patient wellbeing. VLU-related issues are described, such as high exudation with risk of leakage, soiling of clothing and bed linens, and the embarrassment this can cause. This also leads to the need for more frequent dressing changes, and potential dressing-related trauma associated with pain, stress and anxiety. Finally, dressing characteristics that should be considered in order to address these issues and improve the quality of life of patients with VLUs are discussed.

The decisionmaking process of if, and when, to amputate begins at the first patient visit and should be incorporated into the patient discussion early on for all high-risk patients. While prevention of amputation is most commonly the goal, early identification of risk factors and risk stratification can help design a realistic care plan, compassionately inform patient expectations and steward resource allocation. These 10 top tips will help guide you with the plan of care.
