Selective Fasciectomy in Dupuytren’s Contracture: An Experience of A Specialized Tertiary Hospital in Bangladesh

Background: Dupuytren’s disease is a benign yet disabling, irreversible, progressive fibroproliferative condition affecting the palm and fingers, leading to flection contracture of metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints.Objective: To evaluate results of selective fasciectomy to correct the deformity of MCP and PIP joints and observe the complications.Methods: This crosssectional study was done on 30 patients of Dupuytren’s contracture treated by selective fasciectomy, between January 2015 and December 2018, in Department of Orthopaedic Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Selective fasciectomy was done under brachial plexus block, tourniquet control and loupe magnification. Brunner zigzag incision was used. Indications for surgery was MCP flection contracture more than 30⁰ and any degree of PIP flection contracture. Postoperatively hand was immobilised in extension of MCP and PIP joints for 2 weeks and then active and passive movements were encouraged and intermittent splinting for 10 weeks (only at night in last 6 weeks).Results: Among 30 patients, 24 (80%) patients were male, 6 (20%) were female; mean age was 62 years (56-74 years). 12 (40%) cases were bilateral, ring and little fingers involvement were seen in most cases (92%). Mean MCP correction was 53⁰ and mean PIP correction was 34⁰ (p<0.001). There were 3 digital nerve injuries peroperatively which were repaired/reconstructed and protective sensation regained in repaired nerve area at 1 year and 3 (10%) marginal skin loss postoperatively which healed secondarily. Superficial wound infection developed in 3 (10%) patients which healed on dressing and antibiotics. Complex regional pain syndrome developed in 2 (6.66%) patients which were mild and resolved on conservative management. 3 (10%) patients developed scar sequilae which were mild and resolved on conservative treatment. Radial digital artery injury was observed in 1 (3.33%); however, no ischaemic insult was observed postoperatively. 2 (6.66%) patients developed recurrence of the disease who were more than 70 years old; however, they declined further intervention.Conclusion: Selective fasciectomy is an easy and effective procedure with less complication to correct the deformities and improve the gripstrength significantly in Dupuytren’s contracture patients.International Journal of Human and Health Sciences Vol. 06 No. 01 January’22 Page: 41-46

Is a Left-to-Right >2.2°C Difference a Valid Measurement to Predict Diabetic Foot Ulceration in People with Diabetes and a History of Diabetic Foot Ulceration?

Monitoring foot skin temperatures at home have been shown to be effective at preventing the occurrence of diabetic foot ulcers. In this study, the construct validity of using >2.2°C difference between contralateral areas on the foot as a warning sign of imminent ulceration is explored. Thirty participants with diabetes at high risk of ulceration (loss of protective sensation and previous ulceration and/or amputation) monitored their foot temperatures at six sites, four times a day for six days using a handheld infrared thermometer. Walking activity, time of day, and environmental temperature were also monitored and correlated with foot temperatures. We found that contralateral mean skin temperature difference was 0.78°C at baseline. At single sites, left-to-right temperature differences exceeding the threshold were found in 9.6% of measurements ( n = 365), which reduced to 0.4% when individually corrected and confirmed the next day. No correlation was found between contralateral temperature differences and activity, time of day, and environmental temperature. We conclude that using a >2.2°C difference is invalid as a single measurement in people at high risk of ulceration, but the construct validity is appropriate if both individual corrections and next day confirmation are applied.

Preferred Offloading Modalities for Management of Diabetic Foot Ulcers in Private Clinical Settings: A Survey of Australian Podiatrists

Background Diabetic peripheral neuropathy is a common complication of diabetes mellitus. Neuropathy predisposes patients to diabetic foot ulcers (DFU) due to the loss of protective sensation and associated deformities. Management of foot ulcers are multifactorial, but pressure offloading can be considered as one of the most important aspects of management. According to IWGDF Guidelines, non-removable knee-high offloading devices are recommended as the 1st line of treatment for these ulcers. However, this is a very underutilised treatment modality. This study aimed to evaluate the practitioner preferred offloading modalities and reasons for their preference. Methods This project was approved by the university’s human research ethics committee. An online survey was distributed amongst Australian podiatrist via an industry related social media group. The survey collected simple demographical information, management strategies, preferred offloading modalities for the management of diabetic foot ulcers and reasons for their preferred method. Results Sixty-three podiatrists completed the survey with the majority practicing in private clinics. All practitioners treat diabetic foot ulcers regularly with most participants treating up to ten ulcer cases per week and 14% of participants treating more than 20 ulcers per week. Contrary to the IWGDF guidelines, standard therapeutic footwear was the most preferred method of management for the treatment of diabetic foot ulcers, with ease of use reported as the main reason for practitioners using this modality. Non-compliance to the use of non-removable knee-high offloading devices include perceived patient non-compliance and poor tolerance. Conclusion This study shows that practitioners’ offloading strategies do not adhere to the IWGDF guidelines. The reasons for not adhering to the guidelines seems to be a clinical practicality rather than evidence-based practice. Reasons for choosing a management strategy is multi-factorial (not just reducing plantar pressures). Further studies may be required to evaluate the effectiveness of therapeutic footwear in ulcer healing, taking into consideration other factors such as practitioner and patient preference, clinical practicality, and access to support. Based on the findings, this study provides suggestions on how to overcome the barriers that prevent podiatrist from adhering to the recommendations of the IWGDF when selecting offloading devices in general clinical practice.

The Performance and Interrater Agreement of Vibration Perception for the Diagnosis of Loss of Protective Sensation in People With Diabetes Mellitus

This study examined the performance of VibraTip for the diagnosis of loss of protective sensation (LOPS) and the interrater agreement of different neurological modalities performed by 3 health care professionals, a consultant diabetologist, a diabetes specialist nurse, and a podiatrist. Diagnosis of LOPS was based on 10-g Semmes Weinstein monofilament testing performed by a consultant diabetologist (reference method), while examination with a 128-Hz tuning form was also performed. The performance of VibraTip for the diagnosis of LOPS was examined using the receiver operating characteristic curves analysis. Interrater agreement was determined by weighted kappa (κ) statistics. Diagnosis of LOPS (%) was 37.5%. Receiver operating characteristic curve analysis showed that VibraTip examination versus 10-g monofilament, both performed by a consultant, could diagnose LOPS ( P < .001). Sensitivity, specificity, positive predictive value, and negative predictive value of VibraTip versus 10-g monofilament, both performed by a consultant (value, 95% confidence interval), was 0.705 (0.591-0.803), 0.836 (0.758-0.897), 0.733 (0.642-0.808), and 0.816 (0.757-0.863), respectively. The interrater agreement among the health care professionals for 10-g monofilament, VibraTip, and 128-Hz tuning fork in neurological assessment was good with κ > 0.61. VibraTip can be used as a screening tool for the detection of LOPS. There was good overall agreement in the results of neurological examination using 10-g monofilament, 128-Hz tuning fork, and VibraTip among health care professionals.

Pudendal flap—a good option for creating neo-scrotum after Fournier’s gangrene: a case series

Scrotal skin loss following Fournier’s gangrene is very distressing to the patients. The management is complex and challenging shown by the multiplicity of flaps and techniques described in the literature. We included a total of 14 patients with the diagnosis of Fournier’s gangrene over a period of 1 year in our department. We used a modified pudendal thigh flap to reconstruct neo-scrotum in patients with scrotal defects resulting from excision and debridement of Fournier’s gangrene. The average age group of the patients in our study was 41.8 years. The average body mass index in our study was 22.36 kg/m2. The average defect size in our study was 7.05 × 13.07 cm2. There was a single case of flap necrosis. Modified pudendal thigh flap produces a neo-scrotum that looks natural in appearance, provides good quality skin cover and cushion to the testes as well as protective sensation.

Reappraising Diabetic Foot Ulcers: A Focus on Mechanisms of Ulceration and Clinical Evaluation

Diabetic foot ulcers (DFU) are one of the most devastating complications of diabetes as they have significant effects on patient morbidity and mortality. Since their first description in the 19th century, our understanding of DFU has evolved as we uncover the mechanisms that mediate ulceration. In this review, we aim to summarize the various pathways that lead to the development of DFU in order to reappraise physicians’ understanding of these complex wounds. Relevant pathways include the following: (1) neuropathy (motor neuropathy, loss of protective sensation, and autonomic sympathetic dysfunction), (2) vascular disease (arterial ischemia, venous insufficiency, and microvascular changes), and (3) metabolism (signaling and immunological effects of hyperglycemia). We also discuss the clinical presentation of DFU and an evidence-based evaluation to assist clinicians in early identification and classification of these wounds to inform management of DFU. Finally, we summarize complications of DFU caused by the various pathways mediating ulceration and briefly overview DFU management in order to educate physicians about the potential risks if left untreated. A better understanding of the synergistic pathways leading to DFU is essential for clinicians to improve DFU diagnosis, tailor intervention, and mitigate significant patient morbidity and mortality.

Diabetic Peripheral Neuropathy: Diagnosis and Treatment.

Background: Diabetic peripheral neuropathy (DPN) is traditionally divided into large- and small fibre neuropathy (SFN). Damage to the large fibres can be detected using nerve conduction studies (NCS) and often results in a significant reduction in sensitivity and loss of protective sensation, while damage to the small fibres is hard to reliably detect and can be either asymptomatic, associated with insensitivity to noxious stimuli, or often manifests itself as intractable neuropathic pain. Objective: To describe the recent advances in both detection, grading, and treatment of DPN as well as the accompanying neuropathic pain. Methods: A review of relevant, peer-reviewed, English literature from MEDLINE, EMBASE and Cochrane Library between January 1 st 1967 and January 1st 2020. Results: We identified more than three hundred studies on methods for detecting and grading DPN, and more than eighty randomised-controlled trials for treating painful diabetic neuropathy. Conclusion: NCS remain the method of choice for detecting LFN in people with diabetes, while a gold standard for the detection of SFN is yet to be internationally accepted. In the recent years, several methods with huge potential for detecting and grading this condition has become available including skin biopsies and corneal confocal microscopy, which in the future could represent reliable endpoints for clinical studies. While several newer methods for detecting SFN have been developed, no new drugs have been accepted for treating neuropathic pain in people with diabetes. Tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors and anticonvulsants remain first line treatment, while newer agents targeting the proposed pathophysiology of DPN are being developed.
