I fear COVID but diabetic foot (DF) is worse: a survey on patients' perception of a telemedicine service for DF during lockdown

AIMS

To evaluate the patients' perceptions of telemedicine visits during COVID-19 lockdown and their level of anxiety about COVID and diabetic foot (DF).

METHODS

In May 2020, we contacted by phone all the patients who underwent in March and April to remote monitoring visits for DF during the lockdown for COVID-19, with a structured interview, focusing on their perceptions about telemedicine service for DF and on the anxiety toward COVID and DF.

RESULTS

We analyzed 257 remote monitoring visits in 211 patients. Two hundred and six patients answered the follow-up interview; 177 patients (85.9%) remembered the monitoring visit, 140 (67.9%) the health care professional and 181 patients (87.9%) the reason of contact; 169 patients were alone during the visit, 37 with a relative. Patients judged useful both the monitoring during pandemic (4.35 ± 0.28 on a maximum of five) and the possibility to continue after the lockdown (4.34 ± 0.23 on a maximum of five). Eventually, we observed that DF patients were more worried by DF than by COVID on a scale from 0 (not fear at all) to 5 (terrified) (4.79 ± 0.05 vs. 3.27 ± 1.03, p < 0.05). This difference was higher in previously ulcerated patients (4.84 ± 0.03 vs. 3.03 ± 1.13, p < 0.05) and even more in amputees (4.93 ± 0.03 vs. 2.73 ± 1.21, p < 0.05).

CONCLUSIONS

DF patients appreciated televisits during lockdown and the continuation of this service after its end. In this context DF prevails on COVID in the worries of patients, especially if they are recurrent ones.

Injury of the brachial artery accompanying simple closed elbow dislocation: a case report

Background:

Elbow dislocation is the second common dislocation in adults, after the shoulder. The anatomical proximity to the joint of the brachial artery could lead to concomitant vascular injuries, even if their occurrence remains very rare.

Method:

It is reported the case of a right-hand-dominant 42-year-old man who sustained a simple closed posterior elbow dislocation of his left elbow, associated to a complete brachial artery rupture. He urgently underwent the reduction of the joint dislocation and an artery-repairing surgical procedure using a graft from ipsilateral saphenous vein.

Results:

The full functional capacity of the elbow was obtained.

Conclusions:

The abundance of the brachial artery collateral network may hide the presence of a vascular injury, potentially associated to a closed elbow dislocation. Therefore, a high index of suspicious should be maintained. The Emergency Team plays a crucial role in its early diagnosis, which is essential to avoid irreversible ischemia related damages. A prompt reduction of the joint dislocation and the vascular injury surgical repair are required. Regarding the treatment of the concomitant collateral ligaments and capsular injuries, the indication to proceed to the simultaneous ligaments reconstruction is still controversial in literature.

A 2-free-end flexor carpi radialis tendon graft for treating a complex index finger extensor tendon injury

Background:

Volar plating has increasingly become the most used technique for the treatment of unstable distal radius fractures due to the low soft-tissue disturbance and its biomechanical reliability, which allows the early mobilization of the wrist. One of the main goals of the volar locking compression plates design is to avoid those soft tissue complications historically associated to the dorsal plating. However, extensor tendon complications can not be completely excluded.

Method:

The authors report the case of a patient with a complete rupture of the index finger extensor tendons after volar plate fixation of the distal radius. Due to the presence of a severe tendons retraction with a 4-centimeter gap and the neighbouring soft tissues damage, it was decided to fill the gap with a 2-free-end autograft harvested from the Flexor Carpi Radialis (FCR) tendon, using the volar surgical approach performed to remove the plate.

Results:

At the 2-month follow-up, the patient showed the complete recovery of the flexion-extension movements.

Conclusions:

Even though the 2-free-end FCR tendon graft is not commonly reported for the reconstruction of extensor tendons defects, we assume it deserves to be considered as an adequate technique whenever the neighbouring tendons are critically compromised. (www.actabiomedica.it)

Ceramic on ceramic total hip arthroplasty and liner fracture. Two case reports and review of literature

BACKGROUND AND AIM OF THE WORK

Ceramic on ceramic bearing surfaces in total hip arthroplasty are rising in number with the purpose of reducing debris osteolysis in young patients. New generation ceramics drastically reduced the well known problem of liner's fracture associated with this material but this still represents a complication.

METHODS

We present the only two cases of acetabular liner fracture we had in our department, on a total of 252 patients, since we use CoC bearing surfaces in THR (2005-2019) analyzing symptoms and causes of this complication. Review of recent literature focused on symptoms and causes of liners fracture, well matched our cases.

RESULTS

In line with the analysis of literature, the major cause of liner fracture is neck-cup impingement resulting in the "edge-loading" effect, followed by other factors like prosthesis design, traumas and patient weight. From data also emerge the role of acoustic phenomena (e.g. squeaking) and CT scan in the diagnostic process.

CONCLUSIONS

Last generation ceramics should be used in CoC THR, implant malposition and prosthesis design have a dominant role in liner fracture, squeaking should always be investigated. CT scan have an important role in diagnosis. Implant revision with substitution of the bearing surfaces is mandatory in case of fracture or impending fracture signs.

Safety and effectiveness of therapeutic magnetic resonance in diabetic foot ulcers: a prospective randomised controlled trial

OBJECTIVE

To test the efficacy and safety of therapeutic magnetic resonance (TMR) in the management of diabetic foot ulcers (DFU), the authors designed a prospective randomised controlled trial in three highly specialised diabetic foot clinics.

METHOD

All the patients consecutively visited in a period of 18 months were screened according to the inclusion (presence of an ulcer >1 cm² in the foot lasting at least 6 weeks; ABPI>0.6; consent to participate in the study) and exclusion (Charcot's foot; local or systemic infections; chronic renal failure; any wearable electrically-driven life-supporting device) criteria. Patients, who were treated according to international guideline protocols, were randomised into two groups: group A received for four weeks the sham application of TMR, while group B received the active TMR for the same period. People were followed-up to 10 weeks and healing rate (HR), healing time (HT), rate of granulation tissue on wound bed (% GT), reduction of the area of the lesion (∆AL) and a score (0-3) evaluating erythema, oedema, pain and tenderness, respectively, were measured. Adverse events (AE) were registered and monitored throughout the study.

RESULTS

No differences were observed in HR, HT and ∆AL between the two groups during follow-up, while % GT and the scores for erythema, oedema and pain at 10 weeks showed significant (p<0.05) improvements in group B compared with group A and versus baseline. When restricted to non-ischaemic patients (ABPI>0.8), ∆AL was significantly (p<0.05) more pronounced in group B than in group A. No difference in AE occurrence was observed between the two groups.

CONCLUSION

Our study, despite not being able to demonstrate the effectiveness of TMR on healing rate at 10 weeks, with 4 weeks of active treatment in neuro-ischaemic DFUs, shows positive effects on clinical aspects of the DFU and is associated with a significant increase of GT in the wound bed.

DECLARATION OF INTEREST

The study has been fully sponsored by Thereson S.p.A., manufacturer of TMR devices.

Iloprost in the management of peripheral arterial disease in patients with diabetes mellitus

Diabetic complications in the lower extremities, especially those secondary to diabetic macroangiopathy, have increasingly become a clinical emergency, given the high prevalence and progression of the disease. Until recently, the only approach to treating advanced stage disease was medical therapy and major amputation; however, the advent of revascularization procedures has radically improved the prognosis of patients with critical lower limb ischemia. In this setting, iloprost holds a dual position: as first-choice therapy in patients ineligible for revascularization and as complementary therapy in candidates for surgical or endovascular revascularization.

A Randomized Controlled Trial to Examine the Efficacy and Safety of a New Super-Oxidized Solution for the Management of Wide Postsurgical Lesions of the Diabetic Foot

This randomized trial was done to test the effectiveness and safety of using a novel antiseptic solution (Dermacyn® Wound Care [DWC], Oculus Innovative Sciences, Petaluma, CA) in the management of the postoperative lesions on the infected diabetic foot. 40 patients with postsurgical lesions wider than 5 cm2 left open to heal by secondary intention were randomized into 2 groups. Group A was locally treated with DWC, whereas group B received povidone iodine as local medication, both in adjunct to systemic antibiotic therapy and surgical debridement if needed. Ischemia, renal failure, bilateral lesions, or immunodepression were considered as exclusion criteria. Patients were followed up weekly for 6 months. The primary endpoint was healing rate at 6 months, while secondary endpoints were healing time, time to achieve negative cultures, duration of antibiotic therapy, number of reinterventions, and adverse events. Healing rates at 6 months were significantly shorter in group A (90%) than in group B (55%; P < .01). The time taken for cultures to become negative and duration of antibiotic therapy were also significantly (P < .05) shorter in group A than in group B, whereas the number of reinterventions was significantly higher in group B (P < .05). No difference was noted in the adverse events except that for reinfections, which were more frequent in group B than in group A (P < .01). DWC is as safe as and more effective than standard local antiseptics in the management of wide postsurgical lesions in the infected diabetic foot.

Effectiveness and Safety of a Novel Gel Dressing in the Management of Neuropathic Leg Ulcers in Diabetic Patients: A Prospective Double-Blind Randomized Trial

Neuropathic leg ulcers (NLUs) affect more than 10% of diabetic patients with peripheral neuropathy and represent the most common cause of ulceration of the leg in these patients. Though their pathogenesis is well known, related to the chronic neuropathic edema, the management of NLUs, mainly based on elastocompression, is still controversial, with lower healing rates than nondiabetic venous leg ulcers. The authors tested if a novel gel formulation, containing amino acids and hyaluronic acid (Vulnamin® gel; Errekappa, Milan, Italy), will improve the outcomes of NLUs when used together with elastocompression. Thirty patients affected by NLU were randomized into 2 groups, both treated with 4-layer elastocompressive bandaging: patients in group A were topically treated with the application of Vulnamin® gel, whereas patients in group B received only the inert gel vehicle. The healing rate at 3 months was evaluated as the primary endpoint, whereas the secondary endpoints were healing time, reduction in ulcer area and ulceration score in 4 weeks, number of infective complications, and overall satisfaction of patients. Healing rate was significantly ( P < .05) higher in patients in group A when compared with those in group B; healing time, patients’ satisfaction, and reduction in ulcer area and ulceration score in 4 weeks were also higher in patients in group A. However, no significant differences were found in the prevalence of infections and other adverse events. The use of Vulnamin ® gel with elastocompression is safe and effective in the management of NLUs of diabetic patients.

The Epibloc system for the treatment of wrist fractures

The current prospective study was conducted to verify the results obtained in a heterogeneous group of 50 displaced fractures of the wrist treated with the Epibloc system. This method is simple and rapid to use and it does not require plaster. The results obtained are very satisfactory (good and excellent 91.6%) in AO type A2 and A3 fractures and in type C1 fractures (92.8%) and in C2 fractures (88.3%); in fractures with multiple fragments and compromise of the joint surface (C3) the results were not very significant because of the small number of lesions treated (4 cases), but they do not seem to differ very much from what was obtained by other authors when more complicated methods were used. The results were very unsatisfactory in type B fractures (Goyrand); it is our belief that this method is not indicated for lesions such as these, because of the intrinsic difficulty in monitoring dislocation of the volar metaepiphyseal fragment.

Medial fractures of the femoral neck in the elderly treated by SEM bipolar prosthesis

The authors present 335 cases of medical fracture of the femoral neck in the elderly patient (mean age 80.5 years) treated by SEM type bipolar prosthesis. A total of 93 patients (28.3%) were followed-up for a total of 98 hips submitted to surgery (5 bilateral) after a mean period of 42 months, minimum 12 months, maximum 96. Clinical follow-up included these parameters: pain, movement, walking, according to Merle D'Aubigné. Radiographic follow-up consisted in standard views and maximum adduction and abduction. Pain was present in 49% of cases, although it did not significantly invalidate movement (quotients 6 and 5 in 96% of cases); in 60% of the cases there were problems with walking mostly due to the general conditions of the patient. Wear phenomena in the acetabulum were present in 32 hips (32.6%) with no correlation with clinical data. Dynamic x-rays showed that only 31% of the implants maintained intraprosthetic movement. What emerges from the study is the importance of adequate measurement of the prosthetic cupola to improve acetabular fit.

Arthroscopic lateral meniscectomy in adults with stable knees. A medium term evaluation of the results and a comparison with similar lesions of the medial meniscus

The results obtained in 37 cases of arthroscopic meniscectomy in isolated lesions of the lateral meniscus in adult patients are analysed. Isolated lesions were chosen as it is our belief that the results may be considerably influenced by the presence of ligamentous lesions. After an average follow-up of 33 months the results were: excellent, 32; good, 2; fair, 2; poor, 1. The lowest percentage of improvement was observed in subtotal meniscectomies. The presence of changes in the joint cartilage is not always responsible for mediocre results.
