Microsurgery in the Sickle Cell Trait Population: Can it Be Safely and Successfully Performed?

Free-tissue transfer reconstruction in patients with sickle cell anemia risks failure due to polymerization of sickle hemoglobin within the flap microcirculation. However, outcomes vary, as the amount of polymerization is dependent on factors such as disease phenotype/diagnosis, degree of hypoxia, and intracellular dehydration. Most of the literature focuses on patients with sickle cell disease, which produces higher concentrations of sickle hemoglobin and, therefore, is a contraindication to microvascular reconstruction. Fewer reports describe microsurgery in patients with sickle cell trait (SCT) who carry the heterozygous phenotype. Here, we present a case in which a patient with SCT underwent microsurgical breast reconstruction with deep inferior epigastric perforator free-tissue transfer. The 52-year-old woman had previously experienced a failed alloplastic-based reconstruction after radiation therapy for breast cancer. In our case, clinical and Doppler examinations demonstrated that arterial and venous anastomoses had remained patent; so the patient was discharged on postoperative day 4. Blistering developed on postoperative day 8, and by day 15 there was partial necrosis of the inferior-lateral aspect of the deep inferior epigastric perforator flap. Debridement and closure resolved the issue, and at 5 months postprocedure, the flap remained well-perfused and well-incorporated. This case, presented here with patient consent, reports a successful outcome of microsurgical reconstruction in a patient with SCT. It expands the limited evidence to support the safety and feasibility of autologous surgical interventions for patients with the heterozygous phenotype of sickle cell anemia.

Abdominal Wall Reconstruction After Extirpation of a 140-Pound Primary Ovarian Mucinous Adenocarcinoma.

Ovarian cancer is a feared diagnosis for women and clinicians alike. Ovarian mucinous adenocarcinoma is a unique subset of ovarian cancer. As a primary tumor, massive ovarian masses, and more specifically mucinous adenocarcinomas, have been infrequently reported in the medical literature. Team approaches to massive tumor extirpations are essential, as patients often require the expertise of various subspecialists including, but not limited to, gynecologic-oncologists, general surgeons, and plastic and reconstructive surgeons. Here we present a case of a 71-year-old woman with a massive, incapacitating pelvic mass, later found to be a primary ovarian mucinous adenocarcinoma. Once medically optimized, a multi-service team approach was utilized for tumor extirpation and abdominal wall reconstruction. Involved surgical services included Gynecologic-Oncology, General Surgery, and Plastic and Reconstructive Surgery. Exploratory laparotomy for tumor extirpation, hysterectomy, bilateral salpingo-oophorectomy, omentectomy, peritoneal stripping, bilateral inguinal lymphadenectomy, and appendectomy was performed. Extensively thin, devascularized, and attenuated abdominal wall fascia that was adherent to the tumor was removed. The abdominal wall defect was reconstructed and reinforced with inlay and overlays of biologic monofilament mesh. Inverted-T of the vertical and horizontal skin components was performed in a tailor-tacking fashion, assuring the maintenance and protection of the abdominal skin flap vascularity through utilizing the Huger Zones of perfusion. Pathology revealed a stage IA grade 2 mucinous adenocarcinoma of the ovary without evidence of metastasis. No adjuvant therapies were required. The tumor's weight was 140 pounds, and its dimensions were 63 x 41 x 40 cm. It is our hope that presenting this experience will raise awareness of this spectrum of diseases and allow for earlier diagnoses and treatments, as well as exemplify the virtues of a team-based approach in the successful extirpation and subsequent reconstruction of the abdominal wall and skin.

Delayed Thoracodorsal Artery Perforator Free Flap for Calcaneal Degloving Injury Reconstruction.

The thoracodorsal artery perforator (TDAP) flap has a long vascular pedicle that is ideal for lower extremity reconstruction, but it generally relies on the presence of a dominant septocutaneous perforator vessel. Surgical delay optimizes flap survival by creating relative ischemia to augment perforator vessels. In this report, we describe the use of a delayed free TDAP flap in the setting of an absent dominant perforator vessel for the reconstruction of a calcaneal degloving injury. A 22-year-old actively smoking patient with a body mass index of 33.5 presented with a nonhealing left heel wound with overlying necrotic changes after traumatic degloving injury. The entire weight-bearing portion of the calcaneal fat pad and the flanking regions were debrided. The TDAP flap was elevated, revealing three small thoracodorsal artery perforators. Given that a dominant perforator was absent, the flap was surgically delayed. Free-tissue transfer occurred 8 days later. This operation was conducted entirely in left lateral decubitus with simultaneous wound preparation and flap harvest. The flap was elevated on two perforators to elongate the pedicle's length and inset to cover exposed calcaneus and pad the heel. Six months postoperatively, the patient is doing well without flap compromise or ulceration. The TDAP flap is a versatile microsurgical tool, and surgical delay extends the utility of this flap when a dominant septocutaneous perforator is unavailable. Recipient site debridement may occur simultaneously with the TDAP delay procedure. Importantly, only one position is required for flap elevation, microsurgical anastomosis, and insetting, thus obviating intraoperative repositioning.

Primary Cutaneous Secretory Carcinoma: A Case Report and Literature Review.

Cutaneous secretory carcinomas (CSCs) are primary neoplasms of the skin that have been just recently described in the literature through case reports and series. In this case, a cutaneous lesion was found on the left temporal region of an 83-year-old male. He was referred to plastic surgery for complete excision, with negative margins confirmed by pathology. Histology, immunostaining, and genetic testing showed characteristics confirming the diagnosis of CSC and were supported by the information present in the current literature. Our patient showed no evidence of nodal disease or recurrence during regular follow-ups. Given the rarity of CSCs, we aim to present our experience regarding the diagnosis, pathological analysis, and management of our patient as well as summarize the present literature to further open avenues of research.

Technique for Reconstruction of Midcarpal Instability Associated with Lunotriquetral Coalition.

Carpal coalition is a rare congenital presentation of 2 or more fused carpal bones due to a failure of apoptotic segmentation during development. The most common subtype is lunotriquetral coalition (LTC). Most cases are asymptomatic and found incidentally on imaging; however, a few symptomatic cases requiring treatment have been reported. Surgical intervention of arthrodesis and proximal row carpectomy in adults have been reported where conservative management of splinting, physiotherapy, anti-inflammatory medication, or steroid injections have failed. We report a unique case of Minnaar type 2 LTC in a 20-year-old man with a 6-year history of daily right wrist pain and symptomatic wrist instability whose previous conservative therapies failed. Midcarpal instability and volar intercalated segment instability-volar flexion of the lunate-were present. A novel technique using the palmaris longus tendon to reconstruct the triquetrohamate, triquetrocapitate, and dorsal radiolunate ligaments was performed. The graft was secured dorsally to the hamate, triquetrum, and capitate. An additional graft from the lunate to distal radius acted as a biomechanical checkrein. There were no complications. Temporary Kirschner wires were removed 2 months postoperatively, followed by occupational hand therapy. At 1-year follow-up, the patient no longer reported pain or lunotriquetral tenderness. Midcarpal instability and volar intercalated segment instability resolved. Postoperative right wrist flexion and extension were 40 and 75 degrees, respectively. We discuss the successful outcome of this novel technique as an alternative to arthrodesis in the surgical management of LTC.

Lower Extremity Soft Tissue Reconstruction Review Article.

Reconstruction plays a valuable role in the management of lower extremity wounds for limb salvage. The goals of reconstruction are to improve function and quality of life, return to work, and pain reduction while providing a long-lasting durable reconstruction. The plastics and reconstructive surgical approach in conjunction with the orthopedic or trauma team, referred often as the "orthoplastic" approach, can yield the best outcomes for patients. The following sections discuss reconstruction principles and techniques that can be applied broadly for lower extremity wounds secondary to trauma, infection, and tumor resection.

Hidradenitis Suppurativa: A Comparison of Institutional Experience and the Tracking Operations and Outcomes for Plastic Surgeons Registry.

BACKGROUND: Hidradenitis suppurativa is a chronic inflammatory dermatologic condition occurring most commonly in areas with large numbers of apocrine sweat glands. Surgical excision and wound reconstruction are indicated for severe or refractory disease. This study aims to explore institutional reconstructive outcomes following hidradenitis suppurativa excision and compare these to the nationally recognized Tracking Operations and Outcomes for Plastic Surgeons (TOPS) database to determine best-practice guidelines. METHODS: A retrospective chart review of all patients with surgically treated hidradenitis suppurativa from January of 2004 to January of 2016 was performed. Data on patient characteristics, reconstructive methods, and outcomes were collected. Outcomes for each reconstructive method were analyzed and associations between reconstruction and complications were determined. These results were compared to TOPS data. RESULTS: A total of 382 operative sites for 101 individual patients were reviewed. Overall complication rates were 80, 68.3, and 59.6 percent for simple, intermediate, and complex closure, respectively; 68.3 percent for adjacent soft-tissue rearrangement; and 100 percent for split-thickness skin grafts and perforator flaps. Statistical significance was identified between superficial wound dehiscence and adjacent tissue rearrangement compared to intermediate and complex closure (p = 0.0132). TOPS data revealed similar wound breakdown rates for primary closure methods but much lower rates with negative-pressure wound therapy, split-thickness skin grafts, and muscle flaps. CONCLUSIONS: Primary closure techniques for hidradenitis suppurativa wound reconstruction possess high complication rates, whereas improved outcomes are observed with negative-pressure wound therapy, split-thickness skin grafts, and muscle flaps. The correlation in outcomes between our experience and that reported in the TOPS database provides a level of validation to this national database.

Conservative Management of Median Nerve Brachial Plexopathy after Microwave-based MiraDry Treatment for Axillary Hyperhidrosis.

Axillary hyperhidrosis is characterized by excessive sweating of the armpits, which can significantly affect quality of life. A new microwave-based therapy, MiraDry (Miramar labs, Sunnyvale, Calif.), is a promising minimally-invasive treatment option. We report a case of unilateral brachial plexus thermal injury in a thin 19-year-old man treated for axillary hyperhidrosis with the MiraDry system. He initially experienced swelling and pain in the left hand and was prescribed 1 week of methylprednisolone. He then presented 1 week later with induration and swelling of bilateral axillae with swelling of left thumb, left index, and left long fingers, decreased sensation in median nerve distribution of the left hand, and the inability to flex the left index finger DIP joint. EMG showed absent median nerve motor and sensory function, consistent with median nerve plexopathy. He was conservatively managed with close observation and regular occupational hand therapy appointments. At his 12-month follow-up, there was complete return of left pronator teres strength, thumb flexion, and index finger flexion. Decreased sensation remained at the tip of the left index finger. We report the case of median nerve palsy after MiraDry therapy for axillary hyperhidrosis in a thin young man. We recommend using low-energy settings and pre-procedural ultrasound for young, thin patients because of the more superficial course of the brachial plexus within the axilla.

Non-surgical Management of Complex Refractory Pyoderma Gangrenosum With Negative Pressure Wound Therapy With Instillation.

Pyoderma gangrenosum (PG) is a rare skin disorder primarily treated with immunosuppression medication. We report a case of a large, chronic PG wound treated with adjunct negative pressure wound therapy with instillation and dwell time (NPWTi-d) using nonadherent dressing (Mepitel) and reticular open-cell foam with through holes (ROCF-CC) with positive outcomes. The patient was a 62-year-old female with rheumatoid arthritis, Hashimoto's thyroiditis, lymphedema, and morbid obesity who presented with a 19.5 cm x 13.2 cm x 2.1 cm wound of three years duration on the right posterolateral lower extremity that successfully responded to a multimodality approach of immunosuppression and wound vac therapy. We conclude in our case that NPWTi-d with Mepitel and ROCF-CC enhanced the wound healing process, and we discuss NPWTi-d's potential role and benefit as an adjunctive therapy option for chronic and poorly controlled PG on patients taking concurrent immunosuppression.

Use of Botulinum Toxin A to Treat Chemotherapy-Induced Raynaud's Phenomenon.

Raynaud's phenomenon (RP) is a vasospastic disorder of the digital blood vessels leading to pain, paresthesias, and pallor in response to cold or stress. RP can develop secondary to a number of pathologies or factors, including the use of chemotherapy agents. Typical first-line therapies for secondary RP may be contraindicated in patients with certain comorbidities. Here, we discuss a case in which botulinum toxin A (BTX-A) was used to treat chemotherapy-induced RP in a patient with non-small cell lung cancer (NSCLC). We provide a review of the existing literature on the clinical course and treatment modalities, including the use of BTX-A, for patients with secondary RP. A 56-year-old female with NSCLC received treatment with bevacizumab and pemetrexed. Her initial symptoms included progressive discoloration and pain in her fingertips, which hastily progressed to ischemia and subsequent dry gangrene. She was diagnosed with chemotherapy-induced RP, but traditional management options were complicated by acute congestive heart failure. BTX-A injections were administered at key locations on the wrist and hand, significantly improving her symptoms and slowing the progression of the gangrenous changes. RP can develop as sequelae of chemotherapy regimens. Clinical management may be complicated by underlying pathology and/or patient symptoms. BTX-A injections are an excellent non-operative therapeutic option for patients with secondary RP in cases where mainstay therapies may be contraindicated, thus decreasing pain, improving patient quality of life, and slowing the progression of gangrenous changes.

Isolated Scaphoid Dislocation From Low-Energy Wrist Trauma.

Isolated scaphoid dislocation is an extremely rare injury typically caused by high-energy trauma. We present the first observed case of isolated scaphoid dislocation resulting from a non-traumatic injury of the wrist in power-grip tension in a patient with a questionable history of Marfan Syndrome. A 20-year-old right-hand dominant man presented to the emergency department with right wrist pain and deformation after carrying a table. The patient reported a possible history of Marfan Syndrome, but it had never been definitively diagnosed. Imaging revealed radial dislocation of the scaphoid. Bedside closed reduction was performed followed by outpatient ligament reconstruction with return to normal activities at 6 months. Early diagnosis and management lead to an improved prognosis for isolated scaphoid dislocation. Regardless of patient history or mechanism of injury, treatment options include closed reduction, percutaneous fixation, and/or open reduction with internal fixation and ligamentous reconstruction.

Pyoderma Gangrenosum after Fat Grafting in Alloplastic Breast Reconstruction: An Unusual Outcome.

Pyoderma gangrenosum (PG) is a rare and painful inflammatory skin disorder that has been recently associated with breast surgery. It is commonly mistaken for postoperative ischemia or wound infection and does not show response to antibiotics or debridement. We describe the first case of post-surgical PG (PSPG) after alloplastic breast reconstruction involving fat grafting. A 47-year-old woman underwent bilateral mastectomy and 2-stage alloplastic breast reconstruction, with fat grafting from the abdomen. Two days post-surgery, she developed bilateral erythema with tender grouped pustules that progressed rapidly into necrotic ulcerations. She did not respond to antibiotics and serial debridement. Subsequent biopsy confirmed a diagnosis of PG. She was started on steroid therapy and responded well. She was discharged on a steroid regimen, local wound care, and eventually a T-cell inhibitor. Over the next 12 months, her wounds healed without surgical intervention. PSPG has been observed in a variety of reconstructive breast surgeries, but never reported in the setting of fat grafting. As PG involves subcutaneous fat, fat grafting may accelerate and exacerbate the course of disease. Treatment for PSPG includes systemic steroid therapy or other immunomodulatory agents (or both). Surgical management remains controversial, as serial debridement and reconstruction have shown to exacerbate and stimulate disease progression. A long-term follow-up is recommended to monitor for wound healing. Delayed diagnosis of PG in breast reconstruction patients can lead to severe morbidity and disfigurement. This is first case of PSPG following fat grafting in the literature.

Simultaneous Bilateral Patellar Tendon Rupture in a Young Adult Male: A Case Report and Review of the Literature.

A bilateral patellar tendon rupture is extremely rare and has only been documented in case reports. Although the etiology remains unknown, predisposing factors include steroid usage, systemic diseases, and tendinopathies. In the present case, a healthy 33-year-old male with a prior history of bilateral patellar tendonitis and a diagnosis of Osgood-Schlatter disease during adolescence experienced simultaneous bilateral patellar tendon rupture after playing volleyball. He underwent bilateral patellar repair without complications. In the absence of trauma, spontaneous bilateral patellar tendon ruptures are associated with several predisposing factors, including systemic diseases, prior corticosteroid or fluoroquinolone usage, and history of tendinopathy. Injuries can be classified based on the location of the rupture. Bilateral patellar tendon ruptures can be misdiagnosed due to the rarity of cases and the lack of a normal comparative knee. Radiographic techniques can aid in the diagnosis, leading to early surgical treatment and improved outcomes. Early diagnosis and prompt surgical repair contribute to good functional outcomes in this potentially debilitating injury pattern.

Cutaneous Carcinosarcoma: A Small Case Series and Review of the Literature of a Rare Skin Tumor.

Carcinosarcomas are composed of epithelial and mesenchymal elements and primarily present within visceral organs. Despite being potentially aggressive, they are a rare diagnosis in the skin, and few manifestations have been reported to date. In this report, we describe two separate cases of carcinosarcoma presenting as nonhealing scalp wounds. Patient A: a 57-year-old male with a nonhealing skin lesion of ten years successfully treated with wide-local excision and local ortichochea flap reconstruction. Patient B: a 75-year-old female that presented with a painless, slow-growing hemorrhagic mass of 7 years invading the skull and dura ultimately requiring craniectomy and free-tissue transfer with anterolateral thigh flap. Cutaneous carcinosarcomas have more favorable outcomes due to low metastatic rates likely due to earlier detection, but delayed presentation can be fatal. Histopathological analysis is critical for determining diagnosis and prognosis. Adequate reconstruction after wide base excision varies and follows the reconstructive ladder/elevator ranging from primary closure up through free-tissue transfer. With cutaneous manifestations of carcinosarcoma seldom reported in the literature, it is our hope that reporting unusual instances such as this will raise awareness and allow for earlier diagnoses, treatments, and reconstructions.

Extrapleural Superficial Solitary Fibrous Tumor on the Posterior Shoulder: A Case Report and Review of the Literature.

Objective: Mesenchymal in origin, solitary fibrous tumors are primarily seen within the pleura of the lung or in serosal-lined body cavities. Constituting 1% to 2% of all soft-tissue tumors, solitary fibrous tumors are rare entities, especially when found in extrapleural and in superficial locations. A review of PubMed MEDLINE literature for superficial solitary fibrous tumors revealed 71 reports in case reports and small case series. Methods: In this report, we describe a 74-year-old man with an extrapleural superficial solitary fibrous tumor, as well as present a review of the current published literature to date. Results: We present the clinical course, surgical procedure, histopathological features, and treatment options, as well as present a compilation of the published data on superficial solitary fibrous tumors. Conclusions: Based on the current literature, solitary fibrous tumors are more common in middle-aged women and in the head and neck region. Diagnosis of solitary fibrous tumors requires tissue sampling and staining for immunohistochemical markers. Management of these tumors is based on wide local excision with histologically negative margins. If negative margins cannot be surgically achieved, adjuvant therapies including radiation have been described. With extrapleural manifestations of solitary fibrous tumors seldom reported in the literature, it is our hope that reporting these unusual instances will raise awareness of such disease manifestations and allow for earlier diagnosis and treatment.

Injury Risk Estimation Expertise: Assessing the ACL Injury Risk Estimation Quiz.

BACKGROUND: Available methods for screening anterior cruciate ligament (ACL) injury risk are effective but limited in application as they generally rely on expensive and time-consuming biomechanical movement analysis. A potentially efficient alternative to biomechanical screening is skilled movement analysis via visual inspection (ie, having experts estimate injury risk factors based on observations of athletes' movements). PURPOSE: To develop a brief, valid psychometric assessment of ACL injury risk factor estimation skill: the ACL Injury Risk Estimation Quiz (ACL-IQ). STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: A total of 660 individuals participated in various stages of the study, including athletes, physicians, physical therapists, athletic trainers, exercise science researchers/students, and members of the general public in the United States. The ACL-IQ was fully computerized and made available online (www.ACL-IQ.org). Item sampling/reduction, reliability analysis, cross-validation, and convergent/discriminant validity analyses were conducted to refine the efficiency and validity of the assessment. RESULTS: Psychometric optimization techniques identified a short (mean time, 2 min 24 s), robust, 5-item assessment with high reliability (test-retest: r = 0.90) and high test sensitivity (average difference of exercise science professionals vs general population: Cohen d = 2). Exercise science professionals and individuals from the general population scored 74% and 53% correct, respectively. Convergent and discriminant validity was demonstrated. Scores on the ACL-IQ were best predicted by ACL knowledge and specific judgment strategies (ie, cue use) and were largely unrelated to domain-general spatial/decision-making ability, personality, or other demographic variables. Overall, 23% of the total sample (40% of exercise science professionals; 6% of general population) performed better than or equal to the ACL nomogram. CONCLUSION: This study presents the results of a systematic approach to assess individual differences in ACL injury risk factor estimation skill; the assessment approach is efficient (ie, it can be completed in <3 min) and psychometrically robust. The results provide evidence that some individuals have the ability to visually estimate ACL injury risk factors more accurately than other instrument-based ACL risk estimation methods (ie, ACL nomogram). The ACL-IQ provides the foundation for assessing the efficacy of observational ACL injury risk factor assessment (ie, does simple skilled visual inspection reduce ACL injuries?). The ACL-IQ can also be used to increase our understanding of the perceptual-cognitive mechanisms underlying injury risk assessment expertise, which can be leveraged to accelerate learning and improve performance.

Implementation of the Connective Tissue Screening Questionnaire in northeast Pennsylvania to identify comorbidities of connective tissue diseases in subjects with systemic lupus erythematosus.

Previous studies have described an increased risk of developing an additional connective tissue disease (CTD) when one such ailment is present. We examine here the likelihood that individuals with systemic lupus erythematosus (SLE) screen positive for one or more of the following five autoimmune CTDs: Sjögren's syndrome, scleroderma, rheumatoid arthritis, dermatomyositis/polymyositis, and mixed connective tissue disorder. Five hundred SLE-diagnosed subjects were asked to complete a CTD screening questionnaire (CSQ). The results were analyzed according to the set of diagnostic criteria given by the American College of Rheumatology to identify probable cases of each CTD. Significant standardized prevalence ratios and comorbidities indicate an increased risk for the other autoimmune CTDs. In all, 96% of the subjects screened positive for at least one additional CTD, and 13% screened positive for at least two additional CTDs. We see that the SLE-diagnosed population may benefit from further attention regarding the presence of additional CTDs, which may further inform treatment strategies. We also see the application of the CSQ as a potentially important tool for clinical practice, and we describe the present study's limitations along with possible ways that these can be addressed.
