Lactante con nódulos en talones / Infant with nodules on heels

El hamartoma fibrolipomatoso precalcáneo congénito (HFPC) es una entidad benigna e infrecuente caracterizada por la aparición, al nacimiento o meses después, de nódulos de tejido adiposo, simétricos y asintomáticos en las plantas de los pies. Cursa con una evolución favorable, con un crecimiento acorde a la edad del niño. El diagnóstico es clínico, aunque la ecografía podría ser de utilidad. Rara vez precisa pruebas complementarias agresivas o tratamiento alguno. Se presenta un caso clínico de un lactante que recibió dicho diagnóstico. (AU)

Precalcaneal congenital fibrolipomatous hamartoma is a benign and uncommon entity characterized by the appearance at birth or months later of nodules of adipose tissue, symmetrical and asymptomatic in the soles of the feet. It follows a favourable evolution, with a growth according to the age of the child. The diagnosis is clinical, although ultrasound may be helpful. Aggressive follow-up tests or treatment are rarely needed. We present a clinical case of an infant who received such a diagnosis. (AU)

Fractures around Trochanteric Nails: The "Vergilius Classification System".

INTRODUCTION: The fractures that occurred around trochanteric nails (perinail fractures, PNFs) are becoming a huge challenge for the orthopaedic surgeon. Although presenting some specific critical issues (i.e., patients' outcomes and treatment strategies), these fractures are commonly described within peri-implant ones and their treatment was based on periprosthetic fracture recommendations. The knowledge gap about PNFs leads us to convene a research group with the aim to propose a specific classification system to guide the orthopaedic surgeon in the management of these fractures. MATERIALS AND METHODS: A steering committee, identified by two Italian associations of orthopaedic surgeons, conducted a comprehensive literature review on PNFs to identify the unmet needs about this topic. Subsequently, a panel of experts was involved in a consensus meeting proposing a specific classification system and formulated treatment statements for PNFs. Results and Discussion. The research group considered four PNF main characteristics for the classification proposal: (1) fracture localization, (2) fracture morphology, (3) fracture fragmentation, and (3) healing status of the previous fracture. An alphanumeric code was included to identify each characteristic, allowing to describe up to 54 categories of PNFs, using a 3- to 4-digit code. The proposal of the consensus-based classification reporting the most relevant aspects for PNF treatment might be a useful tool to guide the orthopaedic surgeon in the appropriate management of these fractures.

Atypical periprosthetic femoral fractures of the hip: characterisation of three cases.

INTRODUCTION: Long-term use of bisphosphonates (BPs) has been associated with a specific type of tensile side femoral stress fracture known as Atypical Femoral Fracture (AFF). Theoretically periprosthetic femoral fractures (PFF) should be excluded from the diagnosis of AFF. However, emerging evidence correlates prolonged BPs use with the occurrence of a type of PFF with an atypical pattern (atypical PFF, APFF). The aim of the present study is to report 3 cases of APFF treated at a single centre. METHODS: Clinical and radiographic records of PFF that occurred between January 2016 and August 2018 were retrospectively reviewed. All patients meeting the American Society for Bone and Mineral Research (ASBMR) criteria for definition of PFF were included. Management strategies for APFF and patient outcomes, including fracture healing and hip function (assessed by the Oxford Hip Score [OHS]) were collected. RESULTS: 3 patients in the study period were identified as APFF (1 incomplete, 2 complete). All patients were females with a mean age of 83.3 years. All patients were treated with lateral plating. The application of a contralateral strut allograft resulted in fracture healing in cases of complete fractures. Mean OHS at final follow-up was 34.3. CONCLUSIONS: Despite occurring around a hip stem like PFF, APFF had peculiar clinical and radiographic features, making them more similar to AFF. Therefore, the orthopaedic surgeon should also consider the natural history and healing problems associated with AFF prior in order to choose the most appropriate management for APFF.

Abstract The aim of our study was to describe the epidemiological features of pediatric patients with diarrhea caused by Aeromonas spp. and to study the antibiotic susceptibility of this agent during a seven-year period. Aeromonas caviae was identified in 93 stool samples from 52.2% males and 85.6% patients younger than 36 months. The season with the lowest number of isolates was winter (14.4%). Coinfection with other diarrheagenic microorganisms was observed in 31.1% of the cases. The largest number of isolates was obtained from Emergency Department samples (45.6%); 43.3% of the patients presented with fever, 87.8% with diarrhea (43% of these cases were associated with pathological products) and 67.8% with vomiting, while 73.3% of the patients did not require hospital admission. Susceptibility higher than 87% was observed to trimethoprim-sulfamethoxazole, ciprofloxacin, cefotaxime and cefepime. All the patients overcame the infectious process and 63.3% of them did not receive any antibiotic treat-ment during the process. A. caviae was the isolated species associated with intestinal infection. Antibiotic treatment would be specifically indicated in cases selected for their clinical severity. © 2019 Asociación Argentina de Microbiología. Published by Elsevier España, S.L.U.

Stentoplasty of calcaneal fractures: Surgical technique and early outcomes.

Calcaneus is the most common site of hindfoot fracture, frequently caused by fall from height or high energy trauma. The therapeutic strategy ranged from non-operative to ORIF (Open Reduction Internal Fixation). Indications for percutaneous fixation include soft tissue damage or relative contraindications to open surgery. Minimally invasive percutaneous calcaneoplasty should be an alternative to ORIF aiming to reach a stable reduction, early functional recovery and short hospital stay. The aim of our study was to evaluate the clinical and radiographic outcomes of calcaneus fractures treated with balloon calcaneoplasty (BCP) by using a new generation vertebral augmentation system, VBS™-Vertebral Body Stent-DePuy Synthes. A total of 10 patients treated with VBS™ system were recruited for the study. Nine fractures were caused by a fall from height and one case by traffic accident. The mean follow-up was 8.9 months (range 2.6-23.1). The fractures were categorized according to Sanders and Essex-Lopresti classifications (5: type II, 3: type III and 2: type IV; 9: "joint depression" type and 1 case "tongue" type). Radiographic measurement (Böhler's and Gissane's angles) were evaluated at both pre-operative and immediate postoperative time. The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score as well as a subjective evaluation (Visual Analog Scale, VAS) were used for the clinical assessment at the last follow-up. Mean preoperative Böhler's angle was 12.3 ± 8.41° (95% CI 6.3-18.3°), whereas mean preoperative Gissane's angle was 123.66 ± 20.47° (95% CI 109.0-138.3°). At postoperative follow-up mean Böhler's angle increased to 21.51 ± 4.17° (95% CI 18.5-24.5°; p < 0.01), and mean postoperative Gissane's angle was 121.74°±6.82° (95% CI 116.8°-126.6°). Mean AOFAS at the last follow-up was 70.4 ± 17.44 (95% CI 57.9-82.8). Our study demonstrates that percutaneous calcaneoplasty using VBS™ is an effective treatment for calcaneus fracture and capable to implement correction manoeuvre with clinical and radiographic outcomes comparable with other percutaneous stentoplasty.

ABO system is not associated with proximal femoral fracture pattern in Southern Italy.

INTRODUCTION:: The mechanism that leads to a given fracture pattern is not understood. Heredity could act in this field through the ABO system. We investigated the relationship between ABO blood system and hip fracture pattern in a population from Southern Italy. METHODS:: Hip fractures were identified through a registry evaluation of the activity of a level I Hospital, and subsequently classified in 'intracapsular' or 'extracapsular' according to their anatomical location. Information on these patients' ABO blood type was collected and compared with general population data from the report on blood donors of the Salerno division of Italian Blood Volunteers Association (AVIS). RESULTS:: 590 hip fractures were included (414 extracapsular, 176 intracapsular) and compared with 709 blood donors. Fractured patients presented a blood group A more often and blood group O less often than the AVIS population ( p A vs. non-A = 0.0033; p O vs. non-O = 0.0024). None of the ABO blood groups were associated with fracture pattern ( p O vs. non-O = 0.5858, p A vs. non-A = 0.409; p B vs. non-B = 0.253; p AB vs. non-AB = 0.212). The rhesus factor was not associated the fracture pattern ( p = 0.34). CONCLUSIONS:: The ABO blood type could play a role as a risk factor for proximal femoral fractures, but in our population its relevance in influencing the fracture pattern is unclear.

Surgical treatment of neglected hip fracture in children with cerebral palsy: case report and review of the literature.

CASE: A clinical case of a 15-year-old cerebral palsy child with a Sandhu type 2 neglected femoral neck fracture is presented. The patient was treated using cannulated screws and cancellous bone graft augmented with mesenchymal stem cells. At 6 months after the surgery complete fracture healing was observed. CONCLUSION: To early diagnose this fractures, it is mandatory to perform a comprehensive clinical and radiological evaluation including also a second level imaging. The use of cannulated screws with cancellous bone graft and MSCs is a viable treatment option in these patients.

Locking plate fixation of distal femoral fractures is a challenging technique: a retrospective review.

Distal femoral fractures have typically a bimodal occurrence: in young people due to a high-energy trauma and in older people related to a low-energy trauma. These fractures are associated to a very high morbidity and mortality in elderly. Distal femoral fractures might be treated with plates, intramedullary nails, external fixations, and prosthesis. However, difficulties in fracture healing and the rate of complications are important clinical issues. The purpose of this retrospective review was to present our experience in treatment of distal femoral fracture in a sample of older people in order to evaluate the technical pitfalls and strategies used to face up the fractures unsuccessfully treated with locking plates. We included people aged more than 65 years, with a diagnosis of distal femoral fracture, treated with locking plates. We considered 'unsuccessfully treated' the cases with healing problems or hardware failures. Of the 12 patients (9 females and 3 males; mean aged 68.75 ± 3.31 years) included, we observed 3 'unsuccessfully cases', 2 due to nonunions and 1 due to an early hardware failure, all treated using a condylar blade plate with a bone graft. One patient obtained a complete fracture healing after 1 year and in the other cases there was a nonunion. We observed as most common technical pitfalls: inadequate plate lengthening, fracture bridging, and number of locking screws. The use of locking plates is an emerging technique to treat these fractures but it seems more challenging than expected. In literature there is a lack of evidences about the surgical management of distal femoral fractures that is still an important challenge for the orthopaedic surgeon that has to be able to use all the fixation devices available.

Tuberculosis among homeless population from Medellín, Colombia: associated mental disorders and socio-demographic characteristics.

Homeless people are highly susceptible to tuberculosis. It has been suggested that this population have high rates of mental disorders associated with tuberculosis. We assessed tuberculosis incidence, its transmission patterns and association with socio-demographic factors and mental disorders in Colombian homeless people. Prospective study which socio-demographic characteristics and mental disorders were assessed through interviews. Sputa from patients with respiratory symptoms were processed and clinical isolates analyzed by IS6110-RFLP. Multivariate analysis performed by logistic regression model. From 426 homeless studied, tuberculosis incidence found was 7.9 %. 44 % of isolates were clustering. It was found high risk of having tuberculosis associated with income from drugs trade (OR: 3.40 [95 % CI: 1.28-9.05]), dysthymia (OR: 2.54 [95 % CI: 1.10-5.86]) and receiving food from other homeless (OR: 2.47 [95 % CI: 1.16-5.25]). Tuberculosis incidence and degree of transmission are high in homeless studied. Implementing programs to better control tuberculosis among homeless population must consider socio-demographic factors and mental disorders associated with the disease.
