RESUMO
Subacute cutaneous lupus erythematosus (SCLE) is a variant of cutaneous lupus erythematosus (CLE) characterized by distinct skin lesions. Clinical manifestations typically include annular or psoriasiform skin lesions, often localized in sun-exposed areas such as the chest and back. The pathogenesis of SCLE is largely unknown, and contributing factors include genetics, environmental exposures, and immunological dysregulation. SCLE may be idiopathic or drug-induced, with common triggers being calcium channel blockers, thiazide diuretics, and terbinafine. Intravenous immunoglobulin (IVIG) treatment, frequently used in various autoimmune conditions, has a rare association with SCLE. We report a case in which this condition arose during IVIG treatment for chronic inflammatory demyelinating polyneuropathy (CIDP). Knowledge of this rare effect is beneficial to all providers who prescribe IVIG, including neurology, rheumatology, and dermatology.
RESUMO
Cutaneous reactive lymphoid proliferation (CRLP) is a condition that resembles cutaneous lymphoma, and differentiating the two is necessary for proper diagnosis and treatment. It can be idiopathic or caused by viruses, drugs, or skin trauma, resulting in reactive lymphoid hyperplasia. Several clinical and histopathological features are helpful for differentiating CRLP from lymphoma, and they must be considered as a whole to reach the correct diagnosis. The number, location, and progression of CRLP lesions are important clinical clues, while the type, size, arrangement, surface markers, and clonality of the cellular infiltrate are key histopathological clues. We present a case in which CRLP arose in the setting of concomitant antidepressant and antihypertensive use, which are both potential causes of CRLP. In this case, excision served as both diagnosis and treatment. The benign presentation and lack of clonality led to the diagnosis of CRLP. While the cause is unknown, drug exposure was a possible inciting factor, and the patient will be monitored for recurrence.
RESUMO
OBJECTIVE: Catalina Island's Casino Point is a popular scuba diving site and is located 11.6 nautical miles from the University of Southern California Catalina Hyperbaric Chamber. We sought to determine the best method of providing high-performance CPR during a dive emergency, comparing manual cardiopulmonary resuscitation (CPR) with 2 mechanical compression devices during a simulated boat transport. METHODS: This study was performed on a Los Angeles County Lifeguard rescue boat using 3 manikins and comparing 3 arms: 1) manual compressions with 2 rescuers, 2) mechanical CPR with the Autopulse (ZOLL, Chelmsford, MA), and 3) mechanical CPR with the LUCAS III (Stryker, Kalamazoo, WI). CPR data were collected using ZOLL Stat Padz with an accelerometer connected to ZOLL X Series monitor/defibrillators. The manikins were filmed using mounted cameras. Data were reviewed using ZOLL Case Review. RESULTS: In video footage, all 3 arms appeared to provide high-performance CPR during the 30-minute transport. The compression fractions for manual CPR, the Autopulse, and the LUCAS were 99.57%, 95.51%, and 98.4%, respectively. Engine noise (94.6-101.3 dB) prevented the manual arm from hearing their audio prompts, and motion caused significant artifact on the accelerometers. CONCLUSION: High-performance CPR can successfully be performed on a rescue boat by either manual or mechanical methods. Mechanical CPR offered many logistical advantages.

High-pressure water injection injuries of the hand are uncommon, and there is limited literature to guide their treatment. The ideal management of these injuries, whether nonoperative with close observation or early surgical debridement, remains unknown. The authors retrospectively identified a cohort of patients with high-pressure water injection injuries to the hand during a 16-year period. Data collected included demographics, location of injection, hand dominance, type of treatment, need for additional surgery, and complications. The authors attempted to reach all patients by phone and email to assess long-term motion loss, sensation loss, and chronic pain. Nineteen patients met the inclusion criteria. The nondominant hand was involved in 84% and the index finger in nearly half. Two of 10 patients in the early surgery group required additional procedures, including a trigger finger release and serial debridements for Pseudomonas infection. Three of 9 patients without early debridement eventually required surgery, including debridement of a septic flexor tenosynovitis, fingertip amputation, and metacarpophalangeal disarticulation. Sixteen percent of patients developed infection, and 1 patient developed compartment syndrome. This is the largest reported cohort of both operatively and nonoperatively treated high-pressure water injection injuries to the hand. This is the first report of amputation as a complication. Infection and delayed presentation portend a poor outcome. Complications may arise even after early surgical debridement, and long-term sequelae are common. These injuries are not inherently benign and warrant immediate medical attention, early antibiotics, and a low threshold for close observation or surgical debridement.

Postoperative knee stiffness can influence outcomes following operative treatment of multiligament knee injuries (MLKIs). The purpose of this study was to evaluate patient and surgical factors that may potentially contribute to stiffness following surgery for MLKIs. All surgically managed MLKIs involving two or more ligaments over a 10-year period at a single level one trauma center were included in this study. A retrospective review was performed to gather objective data related to the development of knee stiffness after surgery. Patients were classified as "stiff" postoperatively if they (1) had a flexion contracture greater than 10 degrees, (2) failed to reach 120 degrees of flexion at final follow-up, or (3) underwent a manipulation under anesthesia with or without arthroscopic lysis of adhesions to improve range of motion. Patient and surgical factors were evaluated systematically to determine factors associated with stiffness. The mean age of the cohort was 27.6 years at the time of surgery and mean follow-up was 50 weeks. Overall, 26/121 (21.5%) knees were diagnosed with postoperative stiffness. In the acute postoperative phase, 17 patients underwent manipulation under anesthesia. There were no significant differences in age, body mass index, associated injuries, mechanism, external fixation use or surgical timing (acute vs. chronic) between stiff and normal knees. Factors associated with the development of postoperative stiffness included knee dislocation (p = 0.04) and surgical intervention on three or more ligaments (p = 0.04). Careful attention to postoperative rehabilitation regimens should be given to patients with knee dislocations and/or those undergoing reconstruction or repair of three or more injured ligaments. Surgeons may utilize spanning external fixation if necessary without increasing the rate of long-term stiffness. Further, acute surgery does not appear to influence rates of postoperative stiffness or the need for manipulation.

We conducted a study to identify and contrast patterns in the treatment of common injuries that occur in National Football League (NFL) players and National Collegiate Athletic Association (NCAA) Division I football players. Orthopedic team physicians for all 32 NFL and 119 NCAA Division I football teams were asked to complete a survey regarding demographics and preferred treatment of a variety of injuries encountered in football players. Responses were received from 31 (97%) of the 32 NFL and 111 (93%) of the 119 NCAA team physicians. Although patellar tendon autograft was the preferred graft choice for both groups of team physicians, the percentage of NCAA physicians who allowed return to football 6 months or less after anterior cruciate ligament reconstruction was significantly (P = .03) higher than that of NFL physicians. Prophylactic knee bracing, which may prevent medial collateral ligament injuries, was used at a significantly (P < .0001) higher rate by NCAA teams (89%) than by NFL teams (28%). Ketorolac injections were given by a significantly (P < .01) higher percentage of NFL teams (93%) than of NCAA teams (62%). Understanding the current trends in the management of these injuries is beneficial in designing studies that may help improve the treatment and prevention of injuries in football players.

Power and tip pinch are an integral part of intrinsic hand function that can be significantly compromised with dysfunction of the ulnar nerve. Loss of power pinch is one component that can significantly affect an individual's ability to perform simple daily tasks. Tip pinch is less affected, as this task has significant contributions from the median nerve. To restore power pinch, the primary focus must be on restoring the action of the adductor pollicis primarily, and if indicated the first dorsal interosseous muscle and flexor pollicis brevis.

Primary care physicians occupy a vital position to impact many devastating conditions, especially those dependent upon early diagnosis, such as skin cancer. Skin cancer is the most common cancer in the United States and despite improvements in skin cancer therapy, patients with a delay in diagnosis and advanced disease continue to have a grave prognosis. Due to a variety of barriers, advanced stages of skin cancer are more prominent in rural populations. In order to improve early diagnosis four things are paramount: increased patient participation in prevention methods, establishment of screening guidelines, increased diagnostic accuracy of malignant lesions, and easier access to dermatologists. Recent expansion in smartphone mobile application technology offers simple ways for rural practitioners to address these problems. More than 100,000 health related applications are currently available, with over 200 covering dermatology. This review will evaluate the newest and most useful of those applications offered to enhance the prevention and early diagnosis of skin cancer, particularly in the rural population.

BACKGROUND: Recent literature has shown that posterolateral corner injuries of the knee have poor results when treated with repair, when compared to reconstruction. Our study sought to compare outcomes of posterolateral knee injuries treated with repair versus reconstruction and report results from our institution, with the hypothesis that acute repairs have comparable results to reconstructions. METHODS: We identified patients with posterolateral knee reconstruction or repair from January 1, 2000 to March 1, 2012. Patients returned for outcome measures, clinical exam and varus stress radiographs. Further, each patient underwent a chart review. Varus stress radiographs were obtained in 20 control knees, with no history of knee trauma, to our two cohort groups. RESULTS: 26 knees in 25 patients (17 reconstructions and 9 repairs) were evaluated in clinic at mean of 42 months postoperatively for repairs and 38 months postoperatively for reconstructions. Average IKDC scores for reconstruction and repair were 68 and 71, respectively. Average Lysholm scores for these groups were 83 for reconstructions and 83 for repairs. No statistically significant differences existed. Average varus gapping at zero degrees was 8.21 and 8.84 millimeters (mm) for reconstructions and repairs, respectively. Average varus gapping at 20 degrees knee flexion was 11.25 mm for reconstructions and 10.34 mm for repairs. No statistically significant differences were observed in varus gapping between the two groups. Each patient chart was reviewed for complications. There were 2 failures in the 44 patient reconstruction group (4.7%) and 2 failures in the 18 patient repair group (11.1%). We noted a high rate (10/19 patients) of primarily distally-based injuries in our repair group. All failures were treated with revision reconstructions. CONCLUSION: We found low failure rates in both groups. All knees in the repair group were operated within three weeks of injury. Our repair knees had a high rate of distally based avulsion and, were felt to have acceptable tissue that could be successfully repaired. We recommend posterolateral knee repair in cases with distally based avulsions that can be operatively treated within 3 weeks of injury, and have good tissue quality at the time of surgery. LEVEL OF EVIDENCE: IV.

BACKGROUND: In an attempt to improve the accuracy and reproducibility of tunnel positioning, radiographs are being analyzed in an attempt to recreate the native anatomy of the ACL. Understanding the native ACL radiographic anatomy is an essential prerequisite to understand the relevance of postoperative tunnel position. QUESTIONS/PURPOSES: We performed a systematic review of the literature to delineate the radiographic location of the native ACL femoral and tibial footprints. METHODS: A search was performed in March 2014 in PubMed, the Cochrane Collaboration Library, and EMBASE to identify all studies that evaluated the native anterior cruciate ligament (ACL) anatomy on radiographs. Various measurement methods were used in each study, and averages were obtained of the data from studies with the same measurement methods. RESULTS: Fifteen papers were identified (which included data on 177 femora and 207 tibiae in total). Evaluation of the femoral footprint using the quadrant method on lateral knee radiographs showed that the average percent distance location of the anteromedial (AM) bundle and posterolateral (PL) bundle was 22.8% (95% confidence interval (CI) 16.59-28.90) and 32.5% (95% CI 27.71-37.26) from the posterior condyle, respectively, and 23.2% (95% CI 19.52-26.94) and 50.0% (95% CI 46.16-53.76) from Blumensaat's line, respectively. Using the Amis and Jacob method, the tibial footprint on the lateral knee radiograph average percent distances was 35.1% (95% CI 34.46-35.72) for the center of the AM bundle and 47.3% (95% CI 41.69-52.95) for the center of the PL bundle of the ACL. The femoral and tibial ACL footprints on the anteroposterior (AP) views of the knee were not well delineated by these studies. CONCLUSION: The information presented in this systematic review offers surgeons another important tool for accurate ACL footprint identification.
RESUMO
PURPOSE: To analyse one institution's experience with multiligament knee injuries. METHODS: Over 10 years, 133 multiligament knee injuries including 130 patients were included in the study. Inclusion criteria included: (1) injury to two or more knee ligaments (2) multiligament knee repair/reconstructive surgery. RESULTS: The average age at time of injury was 26 years old, and 76 % were male. Fifty-one (38 %) multiligament knee injuries had >2 ligaments injured. Peroneal injuries occurred in 26 patients (20 %), and four (3 %) had associated vascular injuries. A high energy mechanism of injury was noted in 39 %. Twenty-five per cent of patients had an additional orthopaedic injury and, 11.5 % suffered additional non-orthopaedic injuries. Definitive surgical intervention was performed acutely (<3 weeks) in 47 %. Ninety-one per cent of multiligament knee injuries underwent reconstruction with or without repair. Forty-three complications occurred in 37 patients. Patients who suffered >2 ligament injury or had surgery acutely were at an increased risk of knee stiffness requiring manipulation under anaesthesia (MUA) (p = 0.016 and p = 0.047, respectively). Knees with >2 ligaments injured were associated with higher post-operative complications (p = 0.007). Knee dislocation IV knees were at increased risk to undergo revision surgery (p = 0.041). Obese patients were more likely to have a post-operative infection (p = 0.038). Repair, reconstruction or type of graft used had no impact on need for revision surgery. CONCLUSIONS: Multiligament knee injured patients undergoing surgical intervention are a highly complex patient population. This study outlines the patient population, treatment, and complications of one academic institution over 10 years. Overall complications were higher in patients with >2 ligaments injured. Knee stiffness requiring MUA was more common in patients who had >2 ligaments ruptured and those treated acutely. Knees with all four ligaments injured were more likely to undergo revision surgery. LEVEL OF EVIDENCE: Retrospective case series, Level IV.

PURPOSE: Our goal was to evaluate the impact of body mass index (BMI) on complications and associated injuries in patients undergoing surgical treatment for multiligamentous knee injuries (MLKIs). METHODS: Over a period of 10 years, 126 MLKIs (123 patients) were included in the study. The inclusion criteria were (1) injury to 2 or more knee ligaments, (2) multiligament repair and/or reconstruction performed by 1 of 3 sports medicine orthopaedic surgeons at our institution, and (3) minimum of 1 year of follow-up. A chart review was performed to collect demographic data, mechanism of injury, ligaments involved, complications, and associated neurovascular injuries. Lastly, patients were divided by BMI into non-obese (<30 kg/m(2)) and obese (≥30 kg/m(2)) groups. RESULTS: Of the 126 MLKIs, 87 occurred in non-obese patients and 39 occurred in obese patients. Surgical complication rates for non-obese and obese patients were 8.05% and 15.4%, respectively (P = .21). Revisions were needed in 8.05% and 5.1% of patients in these groups, respectively (P = .72). Three wound complications were found in the obese group only. Vascular injuries were found in 2.3% and 7.7% of patients in the non-obese and obese groups, respectively (P = .17). The rates of nerve injuries were 11.49% and 20.51%, respectively (P = .18). Patients in the obese group were most likely to have an MLKI from low-energy mechanisms, disregarding sports-related injuries (51.28%, P = .02). Using a logistic model and BMI as a continuous variable, we found that a 1-unit increase in BMI increased the odds ratio of complications by 9.2%, with statistical significance (P = .0174). In addition, post hoc power analysis using previous literature showed that this study could produce satisfactory power. CONCLUSIONS: Our results indicate that (1) obese individuals are significantly more likely to have an MLKI caused by low-energy mechanisms and (2) complication rates increase by 9.2% for every 1-unit increase in BMI. LEVEL OF EVIDENCE: Level III, retrospective comparative study.
