Clinical characteristics associated with pain in patients with peripheral vascular malformations.

OBJECTIVE: Vascular malformations (VM) can negatively impact the patient's quality of life (QoL). Pain is a common problem in these patients. The aim of this study was to investigate risk factors associated with pain and to assess how pain affects QoL. METHODS: This prospective cross-sectional study was conducted in a tertiary vascular anomaly expertise center. Between June and December 2020, all patients from our local database (334 adults and 189 children) with peripheral VMs were invited to complete the Outcome Measures for VAscular MAlformations questionnaire to evaluate the presence, frequency, and intensity of pain. Additionally, patients were asked to complete several Patient-Reported Outcome Measurement Information System scales to evaluate their QoL. Risk factors associated with pain were identified in bivariate analysis and multivariable logistic regression. QoL domains were compared between patients who experienced pain and patients who did not. RESULTS: A total of 164 patients completed the questionnaire about pain and 133 patients completed all QoL questionnaires. Approximately one-half of the patients (52%) reported pain in the past four weeks and 57% of these patients reported pain daily or several times a week. Female sex (P = .009), lesions located in the upper extremity (P < .001) or lower extremity (P < .001), and intramuscular/intraosseous lesions (P = .004) were independently associated with the presence of pain. The following QoL domains were diminished in patients who experienced pain in comparison with patients who did not: pain interference (P < .001), physical functioning (P < .001), and social participation (P < .001) in adults, and pain interference (P = .001), mobility (P = .001), and anxiety (P = .024) in children. CONCLUSIONS: Pain is a frequently reported complaint in patients with VMs and is present in approximately one-half of the patients. Patients with lesions located in the upper or lower extremity, intramuscular/intraosseous lesions, and female patients are more likely to experience pain. The presence of pain negatively impacted patients' QoL. Although VM are a benign condition and expectative management is frequently applied, our study shows that pain is a serious concern and needs to be actively assessed. Pain is a sign of various etiologies and should be examined to properly treat the pain.

Usefulness of a template-based anterolateral thigh flap for reconstruction of head and neck defects.

BACKGROUND: One of the challenges in head and neck reconstruction is to have an adequate understanding of the three-dimensionalities of the defects created after resections due to the high variability of clinical scenarios. Consequently, it is essential to design the flap to match the requirements of the defect in order to facilitate the insetting and to achieve a successful outcome. The anterolateral thigh flap (ALT) is a robust and versatile flap commonly used in head and neck reconstruction. In this study the authors use a hand-made template as a tool to customize ALT flaps and its variations to fit more accurately the different shapes, volume, and components of the resulting defects. The aim of this study is to describe in detail this surgical approach and present the clinical experience in 100 consecutive cases using a template-based ALT flaps in head and neck reconstruction. METHODS: A retrospective review was performed on all microvascular head and neck reconstruction cases between January 2013 and December 2017 in our institution where a template-based ALT flap design was performed. We describe in detail the surgical technique used and present the clinical outcomes. In addition, we analyzed the use of different designs of the ALT flaps including different flap components in relation to the location of the defect. RESULTS: One hundred reconstructions for head and neck defects were performed in 97 patients. Seven types of ALT free flaps were performed: fasciocutaneous (46%), suprafascial (8%), adipofascial (9%), vastus lateralis muscle (3%), composite fasciocutaneous/adipofascial (9%), chimeric flaps (21%), and vascularized nerve grafts (4%). Oropharyngeal and periauricular defects were mostly reconstructed with fasciocutanoues design. In more complex three-dimensional defects such as skull base or midface defects, a chimeric flap was selected. In all cases the used of template facilitated the insetting of the free flap. The total flap loss was 2%. CONCLUSIONS: Customization of ALT flaps using intraoperative templates is a useful method for flap design which facilitates fitting of the flap to a variety of defects in head and neck reconstruction.

Pyoderma gangrenosum of the hand.

Pyoderma gangrenosum is a rare, painful, ulcerative neutrophilic dermatosis that is not usually seen on the hands. Pyoderma gangrenosum is a diagnosis of exclusion, as there are no specific laboratory or histopathologic findings to confirm the diagnosis. Heightened awareness and early recognition are needed to decrease morbidity in these patients.

Fistula formation to the bladder and to a corpus alienum as a rare complication of diverticulitis: a case report.

BACKGROUND: Fistula formation is a known complication of diverticulitis. Treatment of a diverticular fistula depends on the comorbidity of the patient and the severity of the disease. CASE REPORT: A 59-year-old man presented to the Emergency Department with chronic lower back pain that was being treated with a neurostimulator. He presented with severe sepsis, and an abscess formation near the neurostimulator. An abdominal and pelvic computed tomography scan revealed diverticulitis complicated by fistula formation to the neurostimulator and bladder. He was successfully treated by a two-stage procedure: first, exploration and drainage of the abscess, with removal of the foreign body, followed by a sigmoid resection 1 week later. CONCLUSION: In rare but severe presentations of diverticular disease, it is very important to limit initial treatment to the most threatening disorder.
