El autor en su obra: Pérez Galdós y dos de sus amigos mansos entre persona y personaje

Para describir la compleja sociedad de su tiempo, según su visión del mundo como equilibrio de fuerzas más que de aplicación de dogmas (religiosos o revolucionarios), Galdós no se limita a los recursos del narrador omnisciente o intradiegético, sino que, mediante unos personajes dinamizadores, presenta en debate una visión con matices. Estos personajes no suelen protagonizar la acción y tampoco ser voceros del autor: con un acercamiento ejemplar a El amigo Manso y Electra, se analiza esa postura, que representa la actitud crítica del autor hacia sus tiempos, muy necesitados de espacios de diálogo en los cuales mediar contradicciones y conflictos, ponderando las razones de todos y de cada uno

A Detailed Analysis of Clinical Features and Outcomes of Patients with Pyogenic Spondylodiscitis Presenting without Axial Back Pain

Study design: Retrospective analysis of a single institution prospective, longitudinal database of spinal pyogenic infections. Diagnosis of pyogenic spondylodiscitis (PS) can be challenging. Although presenting symptoms are often non-specific, acute non-remitting axial back pain is the most striking feature. Nevertheless, several authors have reported on the uncommon occurrence of patients with PS without axial back pain. The aim of this study was to characterize presenting symptoms, causative agents, comorbidities, and treatment outcomes of patients presenting with painless pyogenic spondylodiscitis. A total of 214 patients diagnosed with PS were reviewed; patients were divided into two groups: patients presenting with no axial back pain (no pain group, n = 16), and patients presenting with axial back pain (control group, n = 198). Analyzed data comprised general demographics, presenting symptoms, comorbidities, spinal infection location, and amount of spinal involvement. While average age (62.4 vs. 65.0) and sex distribution was similar between the two groups, a significant diagnostic delay was noted in the control group (53 vs. 17 days, p < 0.001). Patients in the no pain group were more likely IV drug abusers or have had liver failure/cirrhosis. Anatomic distribution (i.e., cervical vs thoracolumbar) of the infection did not differ between the two groups, but a higher number of post-surgical infections was noted in the no pain group (37.5 vs. 15.6%, p = 0.026). E. coli and Pseudomonas spp. were more commonly seen in no pain group patients, and mortality was also higher in this group (12.5 vs. 6.0%, p = 0.004)

10-Year Clinical, Functional, and X-ray Follow-Up Evaluation of a Novel Posterior Percutaneous Screw-Rod Instrumentation Technique for Single-Level Pyogenic Spondylodiscitis

Medical treatment with antibiotic therapy remains the mainstay of treatment for pyogenic spondylodiscitis (PS). Nevertheless, orthopaedic treatment is also very important in relieving pain, preventing neurological damage, and avoiding development of spinal deformities (e.g., scoliosis, kyphosis) due to spinal instability. Rigid thoracolumbosacral orthosis (TLSO) bracing is often needed in patients with PS, and average duration of treatment of 3 to 4 months. However, TLSO bracing can be poorly tolerated and limit ability of the patient to go back to a normal life. In 2004 our group developed an alternative surgical treatment to TLSO bracing by percutaneous posterior screw-rod bridge instrumentation of the infected level. This treatment allows early and free mobilization of the patients and is associated with faster recovery, lower pain scores and improved quality of life as previously reported. Herein, we report the clinical outcome of the first 3 patients who have completed the 10 years follow-up mark after the procedure. A case report is also described and details of the procedure are provided

Uncorrect diagnosis of tubercolar spondylodiscitis in aggressive and bone destructive metastasis of melanoma: A case report and literature review

Differential diagnosis of destructive osteolytic spinal lesions can be a diagnostic challenge. In this study, we described a rare case of spinal metastases from primary desmoplastic melanoma which had incorrectly been diagnosed and treated as tuberculous spondylodiscitis. An 82-year-old male patient with ongoing low back pain and a history of lumbar localized Pott's performed a lumbar spine MRI that showed osteolytic lesion with first hypothesis of spondylodiscitis L2-L3. The patient was hospitalized and cause of worsening of the lumbar pain underwent a following series of non-diagnostic CT-guided and open lumbar biopsy at L2-L3 with unsuccessful antibiotic-antitubercular therapy. A new MRI revealed a worsening of previous lesions, extension of the osteolytic lesion at the level of L1-L2 and L3-L4 with neurological impairment. The diagnosis of metastatic melanoma was obtained with surgical decompression and open posterior biopsy procedure. The case described is pathognomonic of the difficulty in detecting the correct diagnosis in front of similar clinical and radiological manifestations. The presence of a previous Pott's disease in the same involved vertebral site was of crucial importance in deflecting the correct diagnostic classification of the pathology, which was possible to ascertain only following an extensive biopsy sampling in the last surgery performed

Fresh autologous stromal tissue fraction for the treatment of knee osteoarthritis related pain and disability

Knee osteoarthritis (KOA) is a very common condition with multifactorial etiology leading to severe pain and disability in the adult population. Although KOA is considered a non-inflammatory arthritis, upregulation of inflammatory and catabolic pathways with increased production of pro-inflammatory cytokines leading to cartilage degradation and extracellular matrix degeneration has been reported. Intra-articular injection of fresh fat derived stromal vascular fraction (SVF) fraction has been proposed as a valid and alternative treatment for symptomatic KOA that guarantees mechanical support through viscosupplementation, anti-inflammatory, and anabolic action. We retrospectively reviewed a case series of 84 consecutive adult patients with KOA who underwent intra-articular injection of fresh fat derived SVF. Significant improvement in pain levels (NRS score decrease 3.5 +/- 1.1, p<0.001), WOMAC pain (-7.02 +/- 3.45 score change, p<0.001), WOMAC stiffness (-1.97 +/- 1.02, p<0.001), and ROM improvement (+17.13 +/- 5.22 degrees, p<0.001). The only complication noted was knee joint swelling lasting for less than 7 days after the injection in 7% of the patients

Revision Surgery Using Retrograde Nail versus Replating in Nonunion Distal Femur Fracture Treated with Plate

Articular distal femur fractures represent 4% to 6% of femur fractures. Locking compression plates (LCPs) are the main treatment option. Nevertheless, a reoperation rate of 12.9% has been reported; nonunion is reported at 4.8%, delayed union at 1.6%, and malunion at 0.6%. Treatment of nonunions can be challenging as no unanimous consensus regarding the best surgical technique has been reached. The aim of this study was to evaluate and compare two types of revision surgery as treatment of LCP-treated articular distal femoral fracture nonunion: retrograde nail or replating. A retrospective cohort study of patients admitted from January 2015 to February 2017 for nonunion of AO/OTA 33C2 fractures previously treated with a lateral LCP was conducted. Patients were treated either with intramedullary nailing (Group A) or with replating (Group B). One independent observer performed clinically and radiographically followed up at 1, 3, 6, 9, 12, 24, and 36 months after surgery. The nonunion scoring system (NUSS) was used. Nine patients were included in our study. The mean follow-up was 2 years. Five patients were treated with intramedullary nailing and four with replating. The NUSS score was 24.2 +/- 6.8 in the nailing group and 37.3 +/- 3 in the replating group (P=0.03). In the nailing group, radiographic consolidation was obtained in all cases. In the replating group, nonunion was found in 3 patients and failure of osteosynthesis in one patient. Therefore, four patients (Group B) underwent implant removal and retrograde femoral nailing, obtaining radiological healing. The union time was 7.6 months in the nailing group. Retrograde intramedullary nailing can be used as an effective treatment of aseptic AO-33C distal femoral nonunion following primary locking plating

A rare case of tertiary syphilis spondylodiscitis of the upper cervical spine: Diagnostic and therapeutic complexity, review of literature

Syphilis is a sexually transmitted disease caused by the spirochetes Treponema pallidum. Syphilitic spinal lesions present as erosive bone lesions often simulating spondylodiscitis or cancer. In this article we describe a rare case of cervical osteolytic lesion from tertiary syphilis. A 45-year-old male with axial neck pain, without fever presented with an isolated osteolytic lesion at C3. Tuberculous spondylitis was initially suspected. A new CT and contrast enhanced MRI of the cervical spine and of the neck showed an extention of the bone lesion at C3 with bilateral lymphadenomegaly. To confirm the diagnosis of tertiary syphilis, US-guided biopsy of the lymph nodes was performed. The patient was treated with i.m. benzylpenicillin 2.4 MIU and the follow-up showed clinical and radiological resolution of the condition. The aim of this case report is to raise awareness of tertiary syphilis in the differential diagnosis of lytic lesions of the spine among the spinal community
