Giant cell tumor of bone: a multicenter epidemiological study in brazil / Tumor de células gigantes ósseas: estudo epidemiológico multicêntrico no brasil

ABSTRACT Introduction: Giant cell tumor of bone (GCTB) mainly affects young adults' long bone epiphyses, threatening bone strength and joint function. Surgery is the primary treatment, although post-surgery recurrence is significant. This study analyzes patient profiles, treatments, and outcomes for GCTB in Brazil. Methods: We retrospectively assessed local recurrence, metastasis, and treatment approaches in 643 GCTB patients across 16 Brazilian centers (1989-2021), considering regional differences. Results: 5.1% (n=33) developed pulmonary metastases, 14.3% (n=92) had pathological fractures, and the local recurrence rate was 18.2% (n=114). Higher rates of pulmonary metastases (12.1%) and advanced tumors (Campanacci III, 88.9%) were noted in lower-income North and Northeast regions. The North also had more pathological fractures (33.3%), extensive resections (61.1%), and amputations (27.8%). These regions faced longer surgical delays (36-39 days) than the South and Southeast (27-33 days). Conclusions: Our findings corroborate international data, underscoring regional disparities in Brazil that may lead to worse outcomes in disadvantaged areas. This highlights the need for improved orthopedic oncology care in Brazil's economically and structurally challenged regions. Level of Evidence III; Retrospective Cohort.

RESUMO Introdução: O tumor de células gigantes do osso (TCG) atinge principalmente epífises de ossos longos em adultos jovens, impactando a resistência óssea e a funcionalidade articular. O tratamento principal é cirúrgico, mas há significativa recorrência pós-operatória. Este estudo analisa o perfil de pacientes e tumores de TCG no Brasil, abordagens de tratamento e resultados. Métodos: Avaliamos retrospectivamente taxas de recorrência, metástase e tratamentos em 643 pacientes tratados em 16 centros brasileiros de 1989 a 2021, considerando a distribuição geopolítica. Resultados: 5,1% desenvolveram metástases pulmonares e 14,3% tiveram fraturas patológicas. A recorrência local foi de 18,2%. Regiões economicamente menos favorecidas, como Norte e Nordeste, mostraram maiores incidências de metástases pulmonares (12,1%) e tumores avançados (Campanacci III, 88,9%). O Norte teve alta ocorrência de fraturas patológicas (33,3%), cirurgias extensas (61,1%) e amputações (27,8%). Nessas regiões, o tempo pré-cirúrgico foi mais longo (médias de 36 e 39 dias) comparado ao Sul e Sudeste (27 e 33 dias, respectivamente). Conclusões: Os resultados refletem disparidades regionais no Brasil, sugerindo que condições socioeconômicas influenciam os desfechos clínicos. Estes achados são importantes para melhorar o cuidado oncológico ortopédico em regiões desfavorecidas do país. Nível de Evidência III; Coorte Retrospectiva.

Anaplastic (undifferentiated) carcinoma of pancreas, an uncommon variant: Diagnosed on endoscopic-guided fine needle aspiration

Anaplastic carcinoma of pancreas (ACP) are rare pancreatic neoplasms. They are well known to be associated with more aggressive tumor behavior and less favorable prognosis than usual pancreatic ductal adenocarcinoma. Endoscopic-guided fine needle aspiration (EUS-FNA) is now a widely accepted modality in diagnosis of pancreatic lesions. However, only a few reports are available describing cytological features of anaplastic carcinoma. Here, we report two cases of ACP diagnosed on EUS-FNA.

Hernia inguinoescrotal gigante: un caso infrecuente

Introducción: Las hernias de la pared abdominal afectan entre el 10% al 15% de la población mundial, siendo hasta el 60% de estas hernias inguinales. Las hernias inguinales gigantes son poco comunes, pero con una gran carga de enfermedad para el paciente. Caso Clínico: Se presenta el caso de un paciente de 51 años, con antecedente de diabetes mellitus tipo II, proveniente de zona rural aislada, por cuatro días de evolución consistente en quemadura escrotal por metal caliente, relacionada a una hernia inguinoescrotal derecha gigante. Es llevado a intervención quirúrgica por cirugía general y urología. Por adecuada evolución clínica se da de alta al 5° día posoperatorio. Discusión: Las hernias inguinales gigantes son raras y frecuentemente se presentan en pacientes de bajo estrato socioeconómico, procedencia rural y cierto grado de negligencia. El reto del equipo quirúrgico consiste en lidiar con los posibles efectos adversos de la reducción del contenido herniario en un abdomen con diversos grados de pérdida del dominio. Se puede requerir resección o debulking del contenido abdominal o la expansión de la cavidad abdominal mediante frenectomía, neumoperitoneo progresivo perioperatorio o la creación de hernias ventrales mediante maniobras avanzadas. La reparación con malla libre de tensión disminuye el riesgo de recurrencia. Conclusión: La hernia inguinal gigante es una patología rara. El cirujano general está llamado a conocer el abanico de opciones que existen en caso de enfrentarse a estos pacientes, lo cual ayuda a reducir la elevada morbimortalidad y altas tasas de recurrencia.

Introduction: Abdominal wall hernias affect between 10% to 15% of the world population and up to 60% of these are inguinal hernias. Giant inguinal hernias are rare, but have high burden of disease for the patients. Clinical Case: We present the case of a 51-year-old patient, with a history of type II diabetes mellitus, from an isolated rural area, with four days of a scrotal burn by hot metal, related to a giant right inguinoscrotal hernia. He is taken to surgical intervention by general surgery and urology. Due to adequate clinical evolution, he was discharged on the 5th postoperative day. Discussion: Giant inguinal hernias are rare and frequently occur in patients of low socioeconomic status, rural origin and a certain degree of neglect. The challenge for the surgical team consist in dealing with the potential adverse effects of reducing hernia contents in an abdomen with varying degrees of loss of normal capacity. Resection or debulking of the abdominal contents or expansion of the abdominal cavity by frenectomy, perioperative progressive pneumoperitoneum, or the creation of ventral hernias by advanced maneuvers may be required. Tension-free mesh repair decreases the risk of recurrence. Conclusion: Giant inguinal hernia is a rare pathology. The general surgeon is called to know the range of options that exist in the event of facing these patients, which helps to reduce the high morbidity and mortality and high rates of recurrence.

Deadly ECG Sign: An Aspect to Recognize in the Settings of STEMI

Learning Objectives: Learn how to identify and differentiate the shark fin EKG pattern from other EKG patterns and abnormalities. Explore the potential diagnostic and prognostic implications of the shark fin EKG pattern, including its association with increased risk of arrhythmias and sudden cardiac death. Background: The Lambda-wave ECG, also known as the Shark fin or Thombostone pattern, has been linked to ST-elevation myocardial infarction's (STEMI) hazardous implications. It is characterized by merged QRS, ST, and T waves, forming a 'triangular QRS-ST-T waveform' or 'giant R waves.' This treacherous signature poses an alarming risk, with chances of cardiogenic shock and ventricular fibrillation leading to fatality. To tackle this peril, implementing swift thrombolysis or percutaneous intervention for reperfusion is critical for successful treatment. For optimal outcomes, the preferred setting to utilize ventricular assist devices is the ICU. Misdiagnosis can happen and be seen as either wide complex tachycardia or ECG changes induced by hyperkalemia. Imperative to prevent severe complications, early detection and treatment are crucial. We are reporting three cases of this Ekg pattern.

Giant Eyelid Eccrine Hidrocystoma: A Case Report

Aims: To report a case of a rare giant eyelid eccrine hidrocystoma confirmed on histopathological examination and successful surgical excision with no recurrence.Presentation of Case: A young male presented with a mass over his eyelid which was gradually increasing in size, leading to drooping of the upper eyelid with no other associated symptoms. The mass 20x15x10 mm was present over the upper lid, non-mobile, non-tender, and firm. On the CT scan, a well-defined round to oval hypodense cystic mass was seen to be originating from the left upper eyelid. The cyst was excised and sent for histopathological analysis. The histological appearance of cystic spaces lined by cuboidal epithelium and containing mucinous fluid was suggestive of eccrine hidrocystoma. There was no recurrence till 2 months of follow-up.Conclusion: Eccrine hidrocystomas are 1-6 mm in size, generally 4 mm, and cysts larger than 10 mm are rare. Larger cysts have been described as “giant eccrine hidrocystoma.” Giant eyelid eccrine hidrocystoma is an unusual condition of the eyelid that must be considered in the differential diagnosis of eyelid tumours. They can be managed by complete surgical excision although recurrences are found to be common.

Argon Beam Coagulation as an Adjuvant for Extended Curettage for Giant Cell Tumors of the Bone: A Study of 50 Cases / Coagulação por plasma de argônio como adjuvante à curetagem estendida em tumores de células gigantes do osso: Um estudo de 50 casos

Abstract Objective Extended curettage with adjuvants of giant cell tumors of bone is associated with a lower rate of recurrence of the tumor while preserving the adjacent joint. The present study was conducted to estimate the recurrence rate and functional outcome after using argon beam as an adjuvant for extended curettage. Methods We selected 50 patients with giant cell tumors, meeting all the inclusion criteria, who underwent extended curettage using high speed burr and argon beam photocoagulation between July 2016 to January 2019. On their follow-up visit, they were assessed for any complaints of pain and signs like tenderness, locally raised temperature, and decreased range of motion of the adjacent joint. Radiologically, the patients were assessed for any increased lucency around the cement mantle and uptake of the subarticular graft. Musculoskeletal Tumor Society Score (MSTS) was administered to the patients, and range of motion of the adjacent joint was compared with the contralateral joint. Results Recurrence was found in 4 patients, that is, an 8% recurrence rate. Twenty-six out of 28 patients with a tumor in the lower limb had a grade-5 weight bearing status 6 months from the surgery, and their range of motion was comparable to contralateral healthy joint with an average MSTS score of 27 (18-30). Conclusion Extended curettage of giant cell tumors using argon beam coagulation is associated with low recurrence rates of the tumor and is an effective modality in the treatment of these tumors besides having a functional outcome comparable to the healthy limb.

Resumo Objetivo A curetagem estendida com adjuvantes de tumores de células gigantes do osso está associada a uma menor taxa de recidiva da neoplasia e à preservação da articulação adjacente. Este estudo foi feito para estimar a taxa de recidiva e o resultado funcional após o uso de plasma de argônio como adjuvante à curetagem estendida. Métodos Cinquenta pacientes com tumores de células gigantes que atendiam a todos os critérios de inclusão foram selecionados para o estudo e submetidos à curetagem estendida com broca de alta velocidade e fotocoagulação com plasma de argônio entre julho de 2016 e janeiro de 2019. À consulta de acompanhamento, os pacientes foram avaliados quanto a quaisquer queixas de dor e sinais como sensibilidade, aumento local da temperatura e diminuição da amplitude de movimento da articulação adjacente. Radiologicamente, os pacientes foram avaliados quanto à presença de qualquer aumento de radiotransparência ao redor do manto de cimento e incorporação do enxerto subarticular. O questionário Musculoskeletal Tumor Society Score (MSTS) foi administrado aos pacientes e a amplitude de movimentação da articulação adjacente foi comparada à articulação contralateral. Resultados Quatro pacientes apresentaram recidiva, o que corresponde a uma taxa de 8%. Seis meses após a cirurgia, 26 de 28 pacientes com tumor no membro inferior tinham capacidade de sustentação de peso de grau 5 e amplitude de movimento comparável à articulação saudável contralateral, com pontuação MSTS média de 27 (intervalo de 18 a 30). Conclusão A curetagem estendida de tumores de células gigantes com coagulação por plasma de argônio está associada a baixas taxas de recidiva da neoplasia; é uma modalidade eficaz no tratamento desses tumores e o resultado funcional é comparável ao do membro saudável.

Effect of Calotropis procera (Aiton) Dryand.based zinc oxide nanoparticles on the cotton pest Spodoptera litura Fab

Major loss in agricultural crops is caused by insect pests. In India, various synthetic insecticides are used against pests. These are much expensive and cause environmental hazards. The nanoparticles, as an alternative approach is gaining considerable interest in this field. In the present study, we explored the biological synthesis of zinc oxide nanoparticles using Giant milkweed, Calotropis procera (Aiton) Dryand. and its effects on the tobacco cutworm, Spodoptera litura. The reduction of zinc ions (Zn2+) to zinc nanoparticles (ZnO NPs) was prepared by mixing 50 g of C. procera leaves with 100 mL of single distilled water in a 250 mL glass beaker. To synthesize nanoparticles, 50 mL of C. procera leaf extract was taken using a stirrer-heater and 5 g of zinc oxide was added at 60ºC, boiled, then kept in a hot air oven at 70ºC for 24 h. Finally, the obtained light yellow coloured powder was carefully collected and characterized using X-ray diffraction (XRD) analysis. The results revealed that the biologically synthesized zinc oxide nanoparticles pesticide was highly effective against the pest. The weight of the pest decreased from low concentration to high concentration. It is concluded that the Calotropis Procera based zinc oxide nanoparticles could be used for the control of Spodoptera litura.

Outcomes of Extended Curettage with and without Bone Allograft for Grade II Giant Cell Tumors around the Knee. A Retrospective Comparative Study / Resultados da curetagem estendida com e sem aloenxerto ósseo para tumores de células gigantes de grau II no joelho. Um estudo comparativo retrospectivo

Abstract Objective This is the first study to establish the utility of extended curettage with or without bone allograft for Grade II giant cell tumors GCTs around the knee joint with the aim of exploring postoperative functional outcomes. Methods We retrospectively reviewed 25 cases of Campanacci grade II GCTs undergoing extended curettage between January 2014 and December 2019. The participants were divided into two groups: one group of 12 patients underwent extended curettage with bone allograft and bone cement, while the other group of 13 patients underwent extended curettage with bone cement only. Quality of life was assessed by the Revised Musculoskeletal Tumor Society Score and by the Knee score of the Knee Society; recurrence and complications were assessed for each cohort at the last follow-up. The Fisher test and two-sample t-tests were used to compare the categorical and continuous outcomes, respectively. Results The mean age was 28.09 (7.44) years old, with 10 (40%) males and 15 females (60%). The distal femur and the proximal tibia were involved in 13 (52%) and in 12 (48%) patients, respectively. There was no significant difference in the musculoskeletal tumor society score (25.75 versus 27.41; p= 0.178), in the knee society score (78.67 versus 81.46; p= 0.33), recurrence (0 versus 0%; p= 1), and complications (25 versus 7.69%; p= 0.21). Conclusions Extended curettage with or without bone allograft have similar functional outcomes for the knee without any major difference in the incidence of recurrence and of complications for Grade II GCTs. However, surgical convenience and cost-effectiveness might favor the bone cement only, while long-term osteoarthritis prevention needs to be investigated to favor bone allograft.

Resumo Objetivo Este é o primeiro estudo a estabelecer a utilidade da curetagem estendida com ou sem enxerto ósseo em tumores de células gigantes (TCGs) de grau II na articulação do joelho com o objetivo de explorar os resultados funcionais pós-operatórios. Métodos Revisamos retrospectivamente 25 casos de TCGs de grau II de Campanacci submetidos a curetagem estendida entre janeiro de 2014 e dezembro de 2019. Os participantes foram divididos em 2 grupos: um grupo de 12 pacientes foi submetido a curetagem estendida com aloenxerto ósseo e cimento ósseo, enquanto o outro grupo, com 13 pacientes, foi submetido a curetagem estendida apenas com cimento ósseo. A qualidade de vida foi avaliada pela Pontuação Revista da Musculoskeletal Tumor Society (MTS, na sigla em inglês) e pela Pontuação da Knee Society (KS, na sigla em inglês), enquanto as taxas de recidiva e complicações foram avaliadas em cada coorte na última consulta de acompanhamento. O teste de Fisher e os testes t de duas amostras foram usados para comparação de resultados categóricos e contínuos, respectivamente Resultados A média de idade dos pacientes foi de 28,09 (7,44) anos; 10 (40%) pacientes eram do sexo masculino e 15 (60%) pacientes eram do sexo feminino. O fêmur distal e a tíbia proximal foram acometidos em 13 (52%) e 12 (48%) dos pacientes, respectivamente. Não houve diferença significativa na pontuação revista da MTS (25,75 versus 27,41; p= 0,178), na pontuação da KS (78,67 versus 81,46; p= 0,33) e nas taxas de recidiva (0 versus 0%; p= 1) e complicações (25 versus 7,69%; p= 0,21). Conclusões A curetagem estendida com ou sem aloenxerto ósseo tem resultados funcionais semelhantes em pacientes com TCGs de grau II no joelho, sem qualquer diferença importante na incidência de recidivas e complicações. No entanto, a conveniência cirúrgica e o custo-benefício podem favorecer a utilização apenas de cimento ósseo, enquanto a prevenção da osteoartrite em longo prazo precisa ser investigada para favorecer o enxerto ósseo.

Giant bladder calculus in a patient with recurrent urinary tract infections / Cálculo vesical gigante em um paciente com infecções urinárias de repetição

A giant bladder stone is rare and is usually defined as "giant" if its weight is over 100g. We describe a 43-year-old man who presented with urinary sepsis, hypotension, abdominal pain, and a vesicocutaneous urinary fistula. Laboratory tests showed hemoglobin 6.6 g/dL, leukocytes 22,700/mm³, creatinine 7.29mg/dL (eGFR 8.8mL/min/1.73m2), urea 181 mg/dL, serum pH 6.99 and bicarbonate 6 meq/L. Abdominal tomography showed bilaterally reduced cortical thickness of the kidneys and a bladder stone of 6x6x11 cm. He was treated with antibiotic therapy, dialysis, and open cystolithotomy.

Giant axonal neuropathy / 中华神经科杂志

Giant axonal neuropathy is a rare neurodegenerative disease in children, which is autosomal recessive inheritance. Giant axonal neuropathy is caused by homozygous or compound heterozygous mutation in the gigaxonin gene on chromosome 16q23.2. Giant axonal neuropathy is a chronic polyneuropathy that affects both the peripheral and central nervous systems. Axonal loss and the presence of giant axonal swellings filled with neurofilaments on nerve biopsy are the pathologic hallmark of this neurodegenerative disorder. The article describes the pathogenesis, clinical manifestation, diagnosis and differential diagnosis of giant axonal neuropathy, to provide reference for clinical diagnosis and treatment of this disease.

Recommendations of diagnosis and treatment of giant cell arteritis and polymyalgia rheumatic in China / 中华内科杂志

Polymyalgia rheumatica (PMR) is a syndrome characterized by pain and morning stiffness in the neck and shoulder and pelvic girdles, as well as raised acute-phase reactants, with or without systemic symptoms, such as fever. Giant cell arteritis (GCA) is a systemic vasculitis of unclear etiology that involves systemic arteries, principally affecting medium- and large-sized arteries with skipped, segmental alterations and granulomatous vasculitis seen on histopathology. In China, epidemiological data describing GCA are still limited; thus, the prevalence might be underestimated. The involvement of vessels in GCA can cause irreversible visual impairment or loss and stroke, which are serious complications. PMR is three times more prevalent than GCA, and other specific diseases should be excluded before the diagnosis is established. PMR symptoms can be present in 40%-60% of patients with GCA. Conversely, GCA can develop in 15% of patients with PMR. Chinese Rheumatology Association, based on the clinical diagnosis and treatment guidelines in 2005, utilizing the experience and guidelines of diagnosis and treatment at home and abroad, formulated this specification to standardize the diagnosis and treatment of GCA and PMR and improve the patient′s prognosis.

Mid-term efficacy of surface knee prosthesis combined with bionic block in joint reconstruction after resection of giant cell tumor in proximal tibia / 中华骨科杂志

A total of 6 patients were treated with surface knee joint prosthesis combined with 3D-printed customized bionic tibial block for reconstruction of bone defect after giant cell tumor (GCT) in proximal tibia (1 male and 5 females, aged 50, 40, 68, 53, 35, 42, respectively). 3 patients with primary and 3 patients with recurrence of GCT. After resection of the tumor, the bone defect was filled with 3D-printed block combined with surface knee prosthesis, the surrounding ligaments were reconstructed with microporous structure and artificial mesh. All cases were followed up for 60, 90, 60, 60, 75, and 50 months, respectively. During the follow-up, there was no local recurrence, no radiolucent lines around prosthesis, and no signs of loosening. The clinical scores of the American Knee Society Score (KSS) were 87, 92, 85, 90, 95 and 78. The functional scores were 70, 100, 70, 100, 100 and 80 respectively. Musculoskeletal Tumor Society Score (MSTS) were 27, 28, 26, 26, 26, 27, respectively. Surface knee prosthesis combined with bionic block can effectively fill the bone defect after resection of GCT in proximal tibia, achieve anatomical and functional reconstruction of knee joint.

Multiple Giant Coronary Artery Aneurysms with Coronary-Pulmonary Artery Fistula / 日本心臓血管外科学会雑誌

Giant coronary artery aneurysms are relatively rare and are usually associated with Kawasaki disease, atherosclerosis, congenital disease, or trauma. Although a coronary-pulmonary artery fistula is a known complication, clear guidelines for treatment of this condition remain unavailable. We report a case of multiple giant coronary artery aneurysms associated with a coronary-pulmonary artery fistula in a patient who underwent fistulotomy, aneurysmectomy, and coronary artery bypass graft surgery. A 66-year-old woman was initially evaluated by her primary care physician following right breast cancer surgery. She denied any specific symptoms; however, she was referred to our hospital for evaluation of an abnormal shadow detected on chest radiography. Contrast-enhanced computed tomography (CT) performed at our hospital revealed multiple giant coronary artery aneurysms(approximately 45 mm in size), as well as right and left coronary-pulmonary artery fistulas. We performed simultaneous aneurysmectomy, fistula resection, and coronary artery bypass grafting for management of the giant coronary artery aneurysms concomitant with coronary-pulmonary artery fistulas. Threedimensional CT was useful for accurate imaging of the location of the coronary artery aneurysms, fistula vessels, and the left anterior descending, and left circumflex arteries. It is essential to accurately delineate the boundary between the aneurysms and healthy coronary arteries and fistula vessels, and coronary artery bypass graft surgery should be performed if necessary. We report a rare case of the aforementioned clinical condition, together with a literature review.

Giant multilocular prostatic cystadenoma:a case report and literature review / 现代泌尿外科杂志

【Objective】 To investigate the clinical characteristics and treatment strategy of giant multilocular prostatic cystadenoma(GMPC). 【Methods】 The clinical data of a GMPC patient treated in our hospital in July 2021 were retrospectively analyzed. The patient was 73 years old. The clinical manifestations were urgent urination and frequent urination. The prostate specific antigen (PSA) increased slightly. MRI showed giant cystic solid space occupying lesion of the prostate. Domestic and foreign cases of prostate cystadenoma from 2000 to 2021 were retrieved for literature review. 【Results】 Transabdominal laparoscopic radical prostatectomy was performed successfully. The postoperative pathological diagnosis was GMPC. Two weeks after operation, the urinary catheter was removed, and there was no discomfort such as urinary frequency or urinary incontinence. After follow-up for more than 8 months, there was no tumor recurrence or metastasis. 【Conclusion】 There are still some disputes about the oncological characteristics and diagnosis and treatment of GMPC, and there is a lack of long-term follow-up results. Laparoscopic prostatectomy is safe and feasible. Most patients have a good prognosis after surgical treatment. It is necessary to formulate an individualized standard treatment plan based on surgery combined with different patients’ conditions to actively improve the prognosis.

The Efficacy of Bisphosphonate in the Treatment of Giant Cell Tumour of the Bone: A Systematic Review and MetaAnalysis

@#Introduction: Anti-osteoclastic mechanism of Bisphosphonate (BP) is crucial to treat Giant Cell Tumour of the Bone (GCTB), however no established guidelines of its use have been published. This systematic review and metaanalysis is the first to summarise recent clinical studies on the subject. Materials and methods: A systematic search was performed based on PRISMA guidelines for clinical trials of BP administration in GCTB. Baseline data including BP regimen, dose and timing was summarised. The primary outcomes assessed were recurrence rate, metastases, survival rate, functional outcome, clinical outcome, radiological outcome, and adverse effect. Results: We identified 8 articles from 2008-2020. Most studies administer 4mg of Zoledronic acid post-operatively, with five studies mentioning pre-operative administration and six studies describing post-operative administration. There was a total of 181 GCTB cases analysed in this study. The BP group presented lower recurrence rate than control group (three studies; Odds Ratio [OR] 0.15; 95% Confidence Interval [CI], 0.05 – 0.43; p<0.05; heterogeneity, I2=0%). As for survival rate, BP group is comparable to control group (two studies; OR 1.67; 95% CI, 0.06 – 48.46; p=0.77; heterogeneity, I2=65%). Conclusion: Bisphosphonate therapy offers satisfactory recurrence rate, functional outcome, clinical outcome, radiological outcome, survival rate and metastases rate in patients with GCTB, with minimal adverse effects. Pre- and post-operative administration of bisphosphonates in combination might be the most beneficial in minimalising the recurrence rate.

A Case Report of Annular Elastolytic Giant Cell Granuloma / 罕见病研究

Annular elastolytic giant cell granuloma(AEGCG) is a rare granulomatous skin condition. We present a case of a 67-year-old man with annular plaques on the face, neck, shoulder, back and upper limbs, and mildly pruritis exceeding one year. Histopathological examination demonstrated granulomatous inflammatory infiltration of lymphocytes, histiocytes and multinuclear giant cells in the middle and the upper dermis, with more local eosinophils. Elastic fiber staining showed that elastic fibers were absent in granuloma area and were engulfed by multinucleated giant cells. Based on the clinical and histopathological findings, a diagnosis of AEGCG was made. The etiology and pathogenesis of this condition are unclear, and atypical manifestations of non-exposed areas can also occur.It is usually related to systemic diseases lacks specific treatment at present.

This is a case report of giant aneurysm in a 10-year old patient presenting with symptoms of headache and vomiting. Cerebral catheter angiogram revealed a large aneurysm in the left middle cerebral artery, M1 segment. The patient underwent left pterional craniotomy, clip reconstruction of the patent artery, and aneurysmectomy. Post operatively the patient had an unremarkable course and was discharged improved after 1 week. Cerebral catheter angiogram was performed after 2 months and revealed no residual aneurysm.

Surgical Case of Coronary-Pulmonary Arterial Fistula with Giant Coronary Artery Aneurysm / 日本心臓血管外科学会雑誌

A 73-year-old woman was diagnosed with coronary artery aneurysms associated with coronary-pulmonary arterial fistula in a preoperative examination for transverse colon cancer. One of the aneurysms (28 mm) originated from a branch of the right coronary artery and the other two (16 and 12 mm) originated from a branch of the left coronary artery. We performed surgery to prevent their rupture because the right coronary artery aneurysm showed a tendency to enlarge. Surgery was performed through a median sternotomy under cardiopulmonary bypass. Suture closure of the inflow and outflow of the aneurysm was performed. The coronary-pulmonary arterial fistula was ligated. In addition, suture closure of the outflow of the coronary-pulmonary artery fistula into the pulmonary artery was performed, under direct view after incision of the pulmonary trunk. No residual shunt blood flow in the coronary-pulmonary arterial fistula was observed on postoperative echocardiography. Furthermore, no coronary aneurysm and coronary-pulmonary arterial fistula was recognized on postoperative coronary computed tomography. The patient made an uneventful recovery and was discharged from the hospital on postoperative day 12.

ABSTRACT Objective Present the preliminary results of a case series using the surgical ankle arthrodesis technique with an intramedullary retrograde nail for bone tumors. Methods We present the preliminary data of 4 patients, 3 males and 1 female, with a mean age of 46,2 (range 32 to 58) years, with histology proven Giant Cell Tumour of bone in 3 and osteosarcoma in 1. The mean resection length of distal tibia was 11,75 (range 9 to 16) cm, and all the patients underwent reconstruction with a tibiotalocalcaneal arthrodesis with an intercalary allograft fixed by a retrograde intramedullary nail. Results Oncological follow-up evolved without evidence of local recurrence or disease progression in all patients. After a mean time of 69.5 (range 32 to 98 months), patients had a mean MSTS12 functional score of 82.5% (range 75 to 90). All tibial arthrodesis and diaphyseal osteotomy sites were fused within 6 months with a return to activities without complications related to coverage skin or infection. Conclusion No complications were recorded; all arthrodesis and diaphysial tibial osteotomy sites fused by 6 months, and the mean follow-up of those patients was 69,5 (range 32 to 988) months, with a mean functional MSTS score of 82,5% (range 75-90). Level of Evidence: IV; Retrospective Case Series.

RESUMO Objetivo Apresentar os resultados preliminares de uma série de casos utilizando a técnica cirúrgica de artrodese do tornozelo com haste intramedular retrógada para tumores ósseos. Métodos Apresentamos os dados preliminares de quatro pacientes, três homens e uma mulher, com idade média de 46,2 (variação de 32 a 58) anos, com histologia comprovada de tumor de células gigantes em três e osteossarcoma em um. O comprimento médio de ressecção da tíbia distal foi de 11,75 (variação de 9 a 16) cm, e todos os pacientes foram submetidos à reconstrução com uma artrodese tibiotalocalcaneana com um aloenxerto intercalar fixado por uma haste intramedular retrógrada. Resultados O acompanhamento oncológico evoluiu sem evidências de recidiva local ou progressão da doença, em todos os pacientes. Após um tempo médio de 69,5 (variação de 32 a 98 meses), os pacientes tiveram uma pontuação média funcional MSTS12 de 82,5% (variação de 75 a 90). Todos os locais de artrodese e osteotomia diafisária tibiais foram fundidos em 6 meses com retorno às atividades de vida diária sem complicações relacionadas à cobertura ou infecção. Conclusão Não foram registradas complicações; todos os locais de artrodese e osteotomia diafisária da tíbia fundiram-se em 6 meses, e o acompanhamento médio desses pacientes foi de 69,5 (variação de 32 a 988) meses, com uma pontuação média funcional MSTS de 82,5% (variação de 75-90). Nível de Evidência IV; Série de Casos Retrospectivos.
