Management of complications of congenital hand disorders

Epidermolysis Bullosa: Pediatric Perspectives

Epidermolysis bullosa (EB) is a group of rare congenital genetic conditions that result in painful blistering of the skin and mucous membranes, which occur with minor trauma or friction. There are many types and subtypes of EB that need to be distinguished, as the management and prognosis of each can vary significantly. We aim to perform an up-to-date literature review on congenital EB for healthcare providers in pediatrics. We performed a review of existing literature in the English language on EB via PubMed Clinical Queries, using key words such as "epidermolysis bullosa", "congenital" and "children". We reviewed EB based on the following subheadings: epidemiology, diagnosis, therapy, prognosis, and clinical prediction guidelines. EB is due to mutation in a number of genes, some types are autosomal dominant while others are autosomal recessive. The underlying mechanism is a defect in attachment between or within the epidermis and dermis of the skin. There are four main types: epidermolysis bullosa simplex, dystrophic epidermolysis bullosa, junctional epidermolysis bullosa, and Kindler syndrome. The diagnosis is suspected based on symptoms and confirmed by skin biopsy and definitive genetic testing. The severity of EB can range from mild to fatal. Severe complications may arise in some EB types and subtypes within the eye, ear, nose, upper airway, gastrointestinal and genitourinary tracts. There is no cure for the condition to date. Optimal management must be multidisciplinary, and involves wound care, pain control, controlling infections, nutritional support, and prevention and treatment of complications. EB presents in different forms. Treatment is supportive. The prognosis of milder forms is good. Children severely affected with EB and their families live a misery life with impaired quality of life. Health care workers must be aware of the suffering in these families and proactively support them.

Preoperative MRI Evaluation of Hand Vessels in Children With Congenital Syndactyly Malformation by a Contrast-Enhanced Three-Dimensional Water-Selective Cartilage Scan

BACKGROUND

It is crucial to preoperatively assess the arteries of the hands in congenital syndactyly malformation (CSM) patients because this information can affect the therapeutic outcome and prognosis.

OBJECTIVE

To investigate the value of a contrast-enhanced three-dimensional water-selective cartilage scan for the preoperative evaluation of CSM in children.

MATERIALS AND METHODS

Contrast-enhanced three-dimensional water-selective cartilage scan 3.0 T magnetic resonance imaging (MRI) performed in 16 clinically diagnosed CSM patients with 17 affected hands. The arteries of the hands were displayed with a focus on the bifurcation position of the common palmar digital arteries (CPDAs) and the maturity of the proper palmar digital arteries (PPDAs). The MRI results were interpreted by consensus between two experienced pediatric radiologists with 10 years of MRI experience each. The MRI findings were compared with the operation results.

RESULTS

Of 51 CPDAs in the 17 affected hands, MRI showed that 30 had an abnormal bifurcation position and 20 had a normal position, and of the 102 PPDAs, 14 were shown to have an abnormal maturity and 85 a normal state, which were confirmed by surgery. The accuracy, sensitivity and specificity for determining the bifurcation position of the CPDAs based on MR maximum intensity projection reconstructed images were 98.04% (50/51), 96.77% (30/31) and 100% (20/20), respectively. The maturity of the PPDAs was judged by MR maximum intensity projection reconstructed images with an accuracy, sensitivity and specificity of 97.06% (99/102), 82.35% (14/17) and 100% (85/85), respectively.

CONCLUSION

Contrast-enhanced three-dimensional water-selective cartilage scan has excellent performance in displaying the bifurcation position of the CPDAs and the maturity of the PPDAs and is of high value for the preoperative evaluation of CSM in children.

Caring for Children With Congenital Upper Extremity Differences

The purpose of this article is to provide information about the changing landscapes in research, treatment, civil rights' protection, disability awareness, and accepted terminology in the care of children with congenital upper limb differences. This knowledge can guide clinical and nonclinical conversations between patients and their families.

One-Stage Extension Shortening Osteotomy for Syndromic Camptodactyly

Syndromic camptodactyly often affects multiple fingers, and severe deformities are common compared to idiopathic camptodactyly. This study aimed to evaluate the use of a one-stage extension shortening osteotomy of the proximal phalanx for patients with syndromic camptodactyly without tendon surgery. Forty-nine cases of syndromic camptodactyly were included. Forty fingers (81.6%) were associated with arthrogryposis multiplex congenita, and nine (18.4%) with other syndromes. Six fingers presented with a moderate form (30° to 60°) of camptodactyly, whereas 43 fingers manifested the severe form (>60°). The mean age at the time of surgery was 8.5 years, and the patients were followed for a mean of 3.9 years. The mean length of the shortening of the proximal phalanx was 4.9 mm, which averaged 17.8% of the proximal phalanx’s original preoperative length. The mean operative time was 25.8 min, and the PIP joint was fixed using Kirschner wires with an average flexion position of 7.6°. The mean flexion contracture improved from 76° preoperatively to 41° postoperatively. The mean preoperative active arc of motion was 23°, which improved to 49° postoperatively. A one-stage extension shortening osteotomy is a straightforward and effective technique for the improvement of finger function through the indirect lengthening of volar structures without the flexor tendon lengthening. The osteotomy could simultaneously correct bony abnormalities. This simple procedure is especially suitable for surgery on multiple fingers in patients with syndromic camptodactyly.

Surgery and Conservative Management of Camptodactyly in Pediatric Patients: A Systematic Review

Camptodactyly is a pediatric hand condition, the treatment of which remains controversial. The authors' aim was to improve patient care through clarifying the definition of camptodactyly and indications for surgical and/or conservative management, summarizing outcomes, and defining risks. A systematic review was conducted of articles in all languages on outcomes following surgical and/or conservative management of idiopathic camptodactyly in children using MEDLINE (Medical Literature Analysis and Retrieval System Online), PubMed, EMBASE (Excerpta Medica database), AMED (Allied and Complementary Medicine), and CINAHL (Cumulative Index of Nursing and Allied Health Literature) (until January 2017). The primary outcome was posttreatment flexion contracture, and the secondary outcomes were indications for surgery, complications, and patient satisfaction. Database searching generated 16 final articles, with 7 case series and 9 retrospective cohort studies. There was a lack of consistency on the definition of camptodactyly and in outcome reporting. All 16 studies received a "Weak" global rating and demonstrated low-quality evidence, suggesting that treatment of camptodactyly with operative or nonoperative measures reduces the degree of flexion contracture in most patients (from pretreatment averages of 20°-85° to posttreatment averages of 5°-37°). There was general agreement that surgery should be reserved for contracture >30° or failure to respond to conservative management. Surgery generally led to more complications compared with conservative management. Only one study reported on functional limitations, and another reported on patient-reported outcomes. Current evidence of the effectiveness of camptodactyly treatment in addressing both joint-specific deformity and patient-perceived function and appearance is insufficient to guide patient care. Future research may consider the development of decision aids to guide patients and families through selecting management strategies and to promote shared decision making.

National Patterns in Surgical Management of Syndactyly: A Review of 956 Cases

Purpose: Being one of the most common congenital hand malformations, syndactyly is repaired by orthopedic, plastic, and fellowship-trained general surgeons. Limited multi-institutional outcomes analyses regarding incidence, timing, and type of repair exist. Methods: All syndactyly cases performed over a 5-year period from 2012-2016 were isolated from the National Surgical Quality Improvement Program Pediatric database. Patient demographics, surgical factors, perioperative outcomes, and risk factors were analyzed using χ², Fisher exact, and t-test analysis. Results: A total of 956 patients who underwent syndactyly repair were identified. Most cases were simple syndactyly with nearly even case distribution among plastic and orthopedic surgeons. Most patients were men and Caucasian. Mean age at the time of surgery was 2.6 years. Most cases were performed as outpatient surgery. Patients of plastic surgeons had significantly more airway abnormalities and shorter operative times. Patients with complex syndactyly had significantly more ventilator dependence, tracheostomy, and comorbidities when compared with those with simple syndactyly. Cases with complex syndactyly also had longer operative times and a higher rate of superficial surgical site infections. Conclusions: Syndactyly repair is a safe procedure with few major or minor reconstructive complications regardless of the surgical specialty or syndactyly type. Patients with complex syndactyly have significantly more preoperative comorbidities with comparable outcomes. orthopedic surgeons have significantly longer operative times than plastic surgeons, likely due to caring for increased number of patients with complex syndactyly.

Treatment of congenital syndactyly

Defined as the union of two adjacent digits, syndactyly is one of the most common congenital deformities. The severity of the malformation depends on the fusion level, the tissues involved in the union, and whether it is isolated or syndromic. In order to improve the hand's appearance and function, surgery is recommended in the great majority of cases, ideally during early childhood (i.e., before entering school). Web space reconstruction is done using local flaps. Depending on the flap design, digital resurfacing can be done with or without skin grafts. While graftless techniques have shorter operating times and no morbidity associated with skin harvesting, their cosmetic outcomes seem to be worse than those of traditional grafting techniques, with more postoperative complications; furthermore, such techniques cannot be used in all cases, especially those with osteoarticular fusions. When the fingertip is involved, paronychial reconstruction is carried out with pulp flaps. The prognosis for these deformities directly depends on their severity, with excellent outcomes in cases of cutaneous fusion, and much less predictable ones when osteoarticular and/or tendinous tissues are involved.

Epidemiology of syndactyly in New York State

BACKGROUND

There is paucity of literature focusing on the incidence and surgical management of syndactyly. In this study, we describe the incidence and rates of surgical management of patients with syndactyly in New York State.

AIM

To describe the incidence and surgical management of patients with syndactyly using an America's population-based database.

METHODS

We conducted a retrospective study using the New York State Statewide Planning and Research Cooperative System. All patients with a diagnosis of syndactyly at birth were identified and followed longitudinally to determine yearly incidence as well as demographic and surgical factors. Descriptive statistics and univariate analyses were used.

RESULTS

There were 3306 newborns with a syndactyly diagnosis between 1997 and 2014 in New York State. The overall incidence was 0.074% or 7 cases per 10000 live births. A small number of patients underwent surgical correction in New York State (178 patients, 5.4%). Among the surgical patients, most of the operations were performed before the age of two (79%). Approximately 87% of surgeries were performed at teaching hospitals, and 52% of procedures were performed by plastic surgeons. Skin grafting was performed in 15% of cases. Patients having surgery in New York State were more likely to have Medicaid insurance compared to patients not having surgery (P = 0.02).

CONCLUSION

Syndactyly occurs in approximately 7 per 10000 live births, and the majority of patients undergo surgical correction before age two. There may be several barriers to care including the availability of specialized hand surgeons, access to teaching hospitals, and insurance status.

Psychosocial recommendations for the care of children and adults with epidermolysis bullosa and their family: evidence based guidelines

Epidermolysis Bullosa (EB) is a group of rare genetic disorders resulting in skin fragility and other symptoms. Commissioned by DEBRA International and funded by DEBRA Norway, this evidence-bases guideline provides recommendations to optimise psychosocial wellbeing in EB.

An international multidisciplinary panel of social and health care professionals (HCP) and people living with EB was formed. A systematic international literature review was conducted by the panel following the Scottish Intercollegiate Guidelines Network (SIGN) methodology. The resulting papers underwent systematic selection and critique processes. Included papers were allocated to 6 different outcome groups to allow data synthesis and exploration: quality of life, coping, family, wellbeing, access to HCP and pain. Based on the evidence in those papers, recommendations were made for individuals living with EB, family and caregivers and HCP working in the field.

Few studies have investigated interventions and which factors lead to better outcomes, but general recommendations can be made. EB is a complex disease impacting enormously on every aspect of psychosocial life. People and families living with EB need access to multidisciplinary support, including psychological guidance, in order to improve quality of life and psychosocial wellbeing. Interventions should stimulate social participation to prevent isolation. People with EB and their families should be able to access a supportive network. HCP should be well supported and educated about the complexity of EB. They should work collaboratively with those around the individual with EB (e.g. schools, employers etc.) to provide psychosocial opportunity and care.

Attention should be paid to the psychosocial impact of EB as well as physical needs. Directions for research are indicated.

Incidence of Acute Complications Following Surgery for Syndactyly and Polydactyly: An Analysis of the National Surgical Quality Improvement Program Database from 2012 to 2014

PURPOSE

Congenital hand differences are infrequent phenomena, and their treatment represents a relatively small fraction of cases performed by hand surgeons. Little is known about the incidence of wound complications and acute postoperative problems given the relative rarity of these procedures. This study sought to characterize the incidence of complications within 30 days of surgery for congenital hand differences.

METHODS

The National Surgical Quality Improvement Program (NSQIP) contains prospective data regarding 30-day morbidity from 64 pediatric centers across the United States. Data from all available years (2012-2014) were queried for Current Procedural Terminology (CPT) codes pertinent to the treatment of congenital hand differences. Bivariate statistics, Fisher exact tests and Poisson 95% confidence intervals (95% CI) were used to assess the incidence of complications and examine risk factors for these outcomes.

RESULTS

We identified a total of 1,656 congenital hand cases that represented 4 different CPT codes, including surgery for simple syndactyly, complex syndactyly, and polydactyly. The overall incidence of complications was 2.2% (95% CI, 1.6%-3.1%; n = 37) with the most common complication being superficial surgical site infection (1.7%; 95% CI, 1.1%-2.4%) followed by related readmission (0.3%; 95% CI, 0.1%-0.7%). There was a higher incidence of complications observed in patients undergoing complex syndactyly repair (5.2% for complex syndactyly repair vs 2.3% for all others).

CONCLUSIONS

The rate of acute complications following procedures to correct syndactyly and polydactyly is low, the most common of which is superficial surgical site infection. The incidence of acute complications may be helpful in counseling patients and families. We suggest that further research must prioritize collecting data on long-term functional outcomes.

End-stage kidney disease in patient with epidermolysis bullosa - what are the treatment options? - case report

Background

Epidermolysis bullosa is a group of diseases caused by mutations in genes for proteins responsible for cells’ anchorage at the dermo-epidermal junction. Their common feature are dysfunctional or even absent connections between cells. The typical clinical sign is the formation of blisters, with possible excessive scarring, in response to minimal skin irritation. End stage renal disease may be one of the comorbidities in patients with epidermolysis bullosa. The implementation of renal replacement therapy may be very difficult in this population. This is mainly due to problems in obtaining the proper dialysis access. The choice of appropriate method may be crucial for patient’s survival.

Case presentation

We present a case of 29-year-old woman with Epidermolysis bullosa caused by laminin 5 gene mutation. The patient suffered from additional conditions: blindness, complete bilateral sensorineural deafness and oesophageal stenosis. When end stage renal disease was diagnosed, the problem of renal replacement therapy had to be faced. There have been few reports concerning ESRD in this specific group of patients in the available literature. In most of them the prognosis was very poor. Nevertheless, we were very determined to overcome all the difficulties. Special procedures and cooperation with the patient’s family allowed us to consider kidney transplantation as a treatment option.

Conclusion

There should be no limitations in renal replacement therapy in patients with epidermolysis bullosa. Haemodialysis, peritoneal dialysis and kidney transplantation are all possible treatment options. Nevertheless, either method requires special procedures.
