Conclusiones: La correcta evaluación de las variables demográficas y clínicas es necesaria para establecer un correcto diagnóstico y plan de tratamiento.

ABSTRACT Introduction: Fournier's gangrene is defined as a specific form of Type I necrotizing fasciitis, which constitutes a rare urological emergency with high mortality. Objective: To characterize Fournier's gangrene in patients treated in the Urology service of the Hospital General Docente "Dr. Agostinho Neto" in the period from January 2008 to December 2018. Method: A descriptive study of demographic and clinical variables (age, gender, mortality, comorbidity, triggering causes, primary site of infection, site of extension of the infection, hospital stay) was carried out in 20 patients. The medical history was the primary source of information. The data were processed using the statistical program SPSS, version 20.0, and descriptive statistics were used to determine the absolute and relative frequencies (percentages) and mean. Results: 100% corresponded to men with an average age of 64.0 years (27-92); mortality made a 40%. Diabetes mellitus was the most frequent comorbidity, in 10 of the patients (50.0%); 12 patients (60.0%) had more than one comorbid process. Skin lesions were the primary cause in 11 (55.0%), and the scrotum was the main site of origin of infection in 55.0%. The mean hospital stay was 37.7 days (7-75 days). Conclusions: The correct evaluation of the demographic and clinical variables is necessary to establish a correct diagnosis and treatment plan.

MRI of the Morel-Lavallée lesion - a case series.

INTRODUCTION: The aim of the study was to review the appearances of Morel-Lavallée (ML) lesions on magnetic resonance imaging (MRI). PATIENTS AND METHODS: 14 patients diagnosed with the ML lesion on MRI were analysed retrospectively (mean age = 35 years). Mechanism of injury, time frame from injury to MRI, location, shape, T1 and proton-density fat-suppression (PDFS) signal intensity (SI), presence of a (pseudo)capsule, septations or nodules within the collection, mass effect and fluid-fluid levels were analyzed. The Mellado and Bencardino classification was utilized to classify the lesions. RESULTS: In most cases, mechanism of injury was distortion. Mean time frame between the injury and MRI was 17 days. Lesions were located around the knee in 9 patients and in the peritrochanteric region in 5 patients. Collections were fusiform in 12 patients and oval in 2 patients. 9 collections were T1 hypointense and PDFS hyperintense. 4 collections had intermediate T1 and high PDFS SI. 1 collection had intermediate T1 and PDFS SI. (Pseudo)capsule was noted in 3 cases. Septations or nodules were found in 4 cases. According to the Mellado and Bencardino, collections were classified as seroma (type 1) in 9, subacute hematoma (type 2) in 1 and chronic organizing hematoma (type 3) in 4 cases. CONCLUSIONS: Characteristic features of ML lesion include a fusiform fluid collection between the subcutaneous fat and the underlying fascia after shearing injury. Six types can be differentiated on MRI, with the seroma, the subacute hematoma and the chronic organizing hematoma being the commonest.

Traumatic Avulsion of Upper Eyelid Skin Following Surgery in a Patient With Multiple Myeloma and Amyloid Light-chain Amyloidosis.

Multiple myeloma (MM) is a common hematologic malignancy. Primary systemic amyloidosis or amyloid light-chain (AL) amyloidosis is a rare disease. PURPOSE: This article presents the case of a patient with MM and AL amyloidosis who experienced a severe case of medical adhesive-related skin injury. CASE STUDY: A 64-year-old man with MM, AL amyloidosis, and diabetes presented with a necrotic wound on his left heel that required surgical debridement. The patient experienced a traumatic avulsion of the right upper eyelid skin during the removal of the corneal abrasion preventive tape as well as traumatic avulsion of the left upper eyelid skin while the patient's face was being cleansed. The avulsed right upper eyelid skin above the tarsus was repaired with a full-thickness skin graft. The partly avulsed left upper eyelid skin was repositioned, and an excisional biopsy was taken. Both upper eyelids healed uneventfully. The biopsy specimen revealed increased amyloid deposition in the dermis, subcutaneous tissue, and areas surrounding the veins and sweat glands. CONCLUSION: This case illustrates the increased risk of medical adhesive-related skin injury and other skin damage in patients with MM and AL amyloidosis. In these patients, the use of tape should be avoided to prevent intraoperative corneal abrasion.

Degloving injury to groin, scrotum and penis due to low-velocity handlebar injury.

Bicycles are a common cause of blunt abdominal trauma causing 5%-14% of injuries. However, impalement or shear injuries from low-velocity mechanism of injury are rare. We report a case of a 14-year-old boy presenting with an extensive left groin injury sustained while cycling one-handed along the pavement at walking pace. The laceration ran for 12-14 cm from the left groin across the pubis to the right and 10 cm inferiorly into the perineum. This inverted the left scrotum and partially degloved the penis. The corpus cavernosa and tunica vaginalis were exposed up to the level of the superficial inguinal ring. Literature on handlebar-impalement injuries is sparse and the majority of penile degloving injuries described in the literature result from alternative mechanisms. This unusual case demonstrates the potential forces involved, and potential damage resulting from handlebar injuries even at low velocity.

Degloving Injury of the Lower Extremity: Report of Two Cases.

OBJECTIVE: The aim of our article is to highlight the importance of the immediate treatment of lower extremity degloving injuries, in order to prevent complications. CASES PRESENTATION: Here we present two cases of degloving injury of the lower extremity, both resulting from motorway accidents. The first one concerned a 65-year-old man suffering from multiple limb fractures and a degloving injury of the right thigh, which was immediately treated with extensive debridement and primary full-thickness skin graft re-approximation. The second case involved a 63-year-old woman who presented with cervical vertebrae fractures and a degloving injury of the left posterior leg, which, due to the severity of her condition, was treated with a delayed approach resulting in skin necrosis, which required surgical debridement, alginate dressing and foam cover. CONCLUSIONS: The optimal approach to treatment of degloving injuries is challenging and they warrant immediate surgical attention. An early diagnosis and the evaluation of tissue viability are important in order to prevent limb-threatening situations.

A Morel-Lavallée lesion of the proximal calf in a young trauma patient: A case report.

RATIONALE: The Morel-Lavallée lesion (MLL) is a closed degloving injury developing when shear force acts between the muscle fascia and the subcutaneous layer. MLLs develop principally in the trochanteric area or the pelvis; lesions in the proximal calf are rare. Acute lesions can be treated conservatively, but chronic lesions are best treated surgically because of a high rate of recurrence. To the best of our knowledge, this is a rare case of successful treatment of an MLL in the proximal calf associated with tibio-fibular shaft fracture. PATIENT CONCERNS: A 14-year-old male visited our emergency room after having been hit by a car. He exhibited direct trauma to the right lower leg and a distal tibio-fibular shaft fracture without an open wound. He underwent surgery to treat the fracture, which was immobilized with splint for 2 weeks post-operatively. At the 3-month follow-up, he complained of a painless, mobile, soft tissue mass in the posteromedial aspect of the proximal calf. Blood circulation was normal and we found no neurological abnormality in the distal region of the lower leg. DIAGNOSIS: A plain radiograph of the right lower leg revealed a proximal, round, radiopaque soft tissue lesion. Ultrasonography revealed a homogeneous, hypoechoic fluid collection. Magnetic resonance imaging revealed fluid of homogeneous signal intensity between the subcutaneous layer and the underlying fascia of the gastrocnemius muscle. INTERVENTIONS: Percutaneous drainage and intralesional steroid injection were performed on several occasions, but the lesion recurred every time. After 5 aspirations, we scheduled surgery. We radically excised the mass and sutured the superficial to the deep fascia to prevent shearing at the surgical plane. OUTCOMES: No complication or recurrence was noted at the 1-year follow-up. LESSON: An MLL in the proximal calf is an uncommon post-traumatic lesion and care must be taken to avoid misdiagnosis. If an MLL is suspected after imaging studies and physical examination, it is important to determine whether the lesion is acute or chronic and to plan treatment accordingly. Appropriate treatment should be given to patients to improve outcomes.

Dermatosis autoinfligida: presentación de un caso y revisión / Self-inflicted dermatosis: presentation of a case and review

Las dermatosis autoinfligidas representan un motivo habitual de consulta, así como un desafío diagnóstico y terapéutico. Se caracterizan por la autoprovocación de lesiones cutáneas de manera consciente o inconsciente en el contexto de trastornos psiquiátricos complejos. Comunicamos el caso de una paciente que consultó al Servicio de Dermatología por úlceras irregulares y sobreinfectadas localizadas en rostro, de 2 meses de evolución. El caso representó una dificultad diagnóstica ya que solo a partir del interrogatorio exhaustivo y los exámenes complementarios, que descartaron otras patologías, se arribó al diagnóstico de úlceras autoprovocadas en contexto de patología psiquiátrica que requirió manejo interdisciplinario. (AU)

Self-inflicted dermatoses are a frequent cause for consultation and represent a diagnostic and therapeutic challenge. They are characterized by the conscious or unconscious self-generation of cutaneous lesions in the context of complex psychiatric disorders. We report the case of a patient who consulted at the dermatology department with two months history of irregular and superinfected ulcers located on the face. This case represented a diagnostic difficulty since only from an exhaustive interrogation and complementary examinations, which ruled out other pathologies, we arrived at the diagnosis of self-inflicted ulcers in the context of psychiatric pathology that required interdisciplinary management.

Hidden degloving rotator cuff tears secondary to glenohumeral dislocation.

BACKGROUND: A rare form of rotator cuff tear (RCT) is observed secondary to glenohumeral dislocation, followed by immediate repositioning, as well as formation of scar tissue between tendons and tuberosities. Radiographic diagnosis of such "degloving" tears is problematic because they are obscured by scar tissue. We aimed to describe characteristics of degloving tears and report outcomes following their arthroscopic repair. METHODS: Among 67 patients who underwent arthroscopic repair of RCTs secondary to shoulder dislocation, we identified 8 patients (12%) (7 anterior dislocations and 1 posterior dislocation), aged 54.5 years (range, 38-61 years), with typical characteristics of degloving tears. Preoperative imaging revealed massive 2- or 3-tendon tears in all patients (6 with a ruptured or dislocated long head of the biceps), evaluated preoperatively and at greater than 2 years, using the absolute and age- and gender-adjusted Constant scores, Subjective Shoulder Value, and Simple Shoulder Test score. RESULTS: The absolute Constant score improved from 27 (range, 17-54) to 89 (range, 62-95). The age- and gender-adjusted Constant score improved from 31 (range, 24-57) to 97 (range, 83-100). The Simple Shoulder Test score improved from 2 (range, 0-4) to 12 (range, 9-12), while the Subjective Shoulder Value improved from 18 (range, 10-30) to 90 (range, 60-100). All patients were very satisfied (63%) or satisfied (37%). CONCLUSION: We have described a particular form of RCT secondary to glenohumeral dislocation, resulting in degloving of the rotator cuff, followed by repositioning of tendons. The formation of scar tissue can obscure tendon tears on ultrasound, in which case further imaging is recommended to ascertain the diagnosis and avoid therapeutic delays.

Degloving injuries with versus without underlying fracture in a sub-Saharan African tertiary hospital: a prospective observational study.

BACKGROUND: Degloving injuries are surgical conditions in which an extensive portion of skin and subcutaneous tissue is detached from the underlying fasciae, muscles, or bone surface. Frequently, there is an association of fracture underlying the degloved area. We aimed to compare the short-term outcomes of degloving injuries with and without underlying fracture. METHODS: A prospective cohort study was conducted. We recruited patients with degloving injuries, and followed them up for 30 days to assess the outcomes. We collected data on socio-demography, cause and mechanism of injury, presence of underlying fracture, presence of shock at admission, injury severity score, location and size of degloving injuries, their management, and short-term outcomes. There were two comparison groups of degloving injuries based on the presence or absence of underlying fracture. We analyzed the differences between the two groups by using Fisher exact test for categorical variables and Student's t test for continuous variables; p values < 0.05 were considered to be significant. Risk ratio was calculated for the short-term outcomes. RESULTS: There were 1.56% (n = 51) of degloving injuries among 3279 admitted trauma patients during the study period of 5 months; 1% (n = 33) with and 0.56% (n = 18) without underlying fracture. For the overall degloving injuries, male-female ratio was 2 and mean age was 28.8 years; they were caused by road traffic crashes in 84%, and resulted in shock at admission in 29%. In the group with underlying fracture, lower limbs were frequently affected in 45% (p = 0.0018); serial debridement and excision of the avulsed flap were the most performed surgical procedures in 22% (p = 0.0373) and 14% (p = 0.0425), respectively; this same group had 3.9 times increased risk of developing poor outcomes (mainly infections) after 30 days and longer hospital stay (26.52 ± 31.31 days, p = 0.0472). CONCLUSION: Degloving injuries with underlying fracture are frequent in the lower limbs, and have increased risk of poor short-term outcomes and longer hospital stay. We recommend an early plastic surgery review at admission of patients with degloving injuries with underlying fracture to improve the flap viability and reduce the infection risk.
