Absceso de psoas iliaco: un desafío diagnóstico / Psoas-Iliac Abscess a dignotic challengen

El absceso de músculo psoas iliaco se considera una rare-za. Su detección ha mejorado con la utilización de imágenes como la tomografía computada o la resonancia magnética. Presentamos una revisión de casos de absceso de psoas-iliaco internados entre julio de 2015 y febrero de 2018 en un hospital de CABA, Argentina.En este periodo se diagnosticaron un paciente conside-rado de origen primario y ocho de origen secundario. Se observó predominio de colecciones asociadas a es-pondilodiscitis. El síntoma más frecuente fue la fiebre. Staphylococcus aureus fue el germen más rescatado en muestras microbiológicas. Se debe tener alto índice de sospecha de esta patología ante la presencia de fiebre, dolor lumbar y en ocasiones alteración de la marcha. El empleo de antibióticos de amplio espectro sumado a la evacuación de colecciones constituyen la estrategia más efectiva

Psoas-iliac muscle abscess is considered a rarity, the use of images such as computed tomography or magnetic reso-nance imaging has improved its detection.This study reviews cases of psoas-iliac abscess in hospi-talized patients between July 2015 and February 2018 in a hospital in CABA, Argentina.In one of the patients the origin was considered primary ,while in the other eight it was secondary. There was a pre-dominance of collections associated with spondylodiscitis. The most frequent symptom was fever. Staphylococcus au-reus was the most frequent organism obtained in microbio-logical samples. A high level of suspicion must be held in the presence of fever, lumbar pain and sometimes alteration of the gait. The use of broad spectrum antibiotics in addition to evacuation of collections is the most effective strategy.

Utilización de ketamina en paciente pediátrico con crisis de dolor en artritis idiopática juvenil. Informe de caso / Using ketamine in a pediatric patient with a pain crisis in juvenile idiopathic arthritis. A case report

Abstract Introduction: Ketamine has been used as a pain management strategy, particularly in adults. There are some clinical data about the use of Ketamine in children but there are no reports referring to its efficacy, specifically in juvenile idiopathic arthritis. Ketamine could therefore become an alternate option in the management of refractory cases. Clinical findings: This report discusses the case of a 7-year-old male patient with a history of juvenile idiopathic arthritis who was admitted to the hospital as a result of an inflammatory pain crisis associated with stiff hands and feet, pain, edema, and enthesitis, in addition to signs of bilateral sacroiliitis, stiffness impairing gait, passive and active movements, poor response to multimodal analgesia with nonsteroidal antiinflammatory drugs, steroids and weak opioids. Adequate pain control and significant improvement of the child's function was achieved after initiating ketamine infusion at analgesic doses. Conclusions: This case provides valuable information about the usefulness of ketamine as a modulator of central sensitization and inflammation that could be extrapolated to a similar population of rheumatology patients.

Resumen Introducción: La ketamina se ha empleado como estrategia analgésica sobre todo en adultos. En los niños existen algunos datos clínicos sobre su uso, sin embargo, no hay reportes que hagan referencia de su efectividad en el caso específico de dolor por artritis idiopática juvenil, dejando esta como una posible alternativa de manejo en casos refractarios. Hallazgos clínicos: El presente reporte describe, el caso de un paciente masculino de 7 años con antecedente de artritis idiopática juvenil, hospitalizado por una crisis dolorosa de tipo inflamatorio asociado a rigidez en pies y manos, con dolor, edema y entesitis y signos de sacroileítis bilateral, dificultad para la marcha y rigidez que lo limitaba para movimientos activos y pasivos, poca respuesta a la analgesia multimodal con AINES, esteroides y opioides débiles, en quien se obtuvo un adecuado control del dolor y mejoría significativa de su capacidad funcional luego de iniciar infusión de ketamina en dosis analgésicas. Conclusión: Este caso nos brinda información valiosa sobre la utilidad de la ketamina como modulador de la sensibilización central e inflamación que podría ser extrapolada a una población similar de pacientes reumatológicos.

PCA affects expression of TF in HUVECs through NF-κB and AP-1 sig-naling pathways / 中国病理生理杂志

AIM:To explore the role of nuclear factor-κB(NF-κB)and activator protein-1(AP-1)signaling pathway in the inhibitory effects of Agkistrodon acutivirus protein C activator(PCA)on lipopolysaccharide(LPS)-induced tissue factor(TF)expression in human umbilical vein endothelial cells(HUVECs).METHODS: The viability of the HUVECs was measured by MTT assay.The protein distribution of tumor necrosis factor-associated factor 6(TRAF6)in the cells was detected by immunohistochemical staining.The protein expression of NF-κB p65,TF,c-Fos and c-Jun was deter-mined by Western blot.The mRNA expression of TF in the HUVECs was detected by qPCR.The content of TF in the me-dium of each group was measured by ELISA.RESULTS:Compared with the control group,the viability of the HUVECs in LPS group decreased significantly(P<0.01), obvious yellow dye particles appeared in the cytoplasm, cytoplasmic stai-ning deepened,and the average absorbance of TRAF6 was increased(P<0.01).The protein expression of NF-κB p65, c-Jun and c-Fos were significantly increased(P<0.01).The expression of TF at mRNA and protein levels were signifi-cantly increased(P<0.01).Compared with the LPS group,the cell viability in PCA +LPS group was slightly increased (P<0.05),the cell morphology was normal,cytoplasmic yellow dye particles were not obvious, and the average absor-bance of TRAF6 was significantly lower than that in LPS group(P<0.01).The protein expression of NF-κB, c-Jun and c-Fos was significantly decreased(P<0.01),and the expression of TF at mRNA and protein levels were decreased(P<0.01).CONCLUSION:PCA significantly reduces the damage of HUVECs induced by LPS.The mechanism may be a-chieved by reducing the activation of TRAF 6,NF-κB and AP-1 nuclear transcription factors,thereby reducing the release of tissue factor.

Pathological mechanics and treatment of plantar fasciitis:future prospects of platelet-rich plasma therapy / 中国组织工程研究

BACKGROUND:The treatments of plantar fasci tis as an important cause of calcaneodynia are different in medical institutions, as wel as the therapeutic results. OBJECTIVE:To summarize various treatments of plantar fascia, and based on the pathogenesis and pathological mechanics of plantar fasci tis, to investigate the effect of various treatment methods and indications. METHODS:A computer-based online search of PubMed database and Wanfang database was performed for articled related to plantar fasci tis published between January 1993 and January 2014. The keywords were “plantar fasci tis, mechanism, treatment”in English and Chinese, respectively, by screening the titles and abstracts. Final y, 34 articles were included in result analysis. RESULTS AND CONCLUSION:The treatment of plantar fasci tis needs to fol ow the principle from noninvasive to invasive treatment. Stretching the plantar fascia and heel cord, using prefab-ricated orthotics, and wearing night splints are crucial for the treatment of plantar fasci tis. Local hormone injection can be used as first-line therapy for patients with acute plantar fasci tis if they can tolerate the adverse reactions due to hormone therapy. Platelet-rich plasma therapy has a promising prospect, but there is lack of experimental evidences. Extracorporeal shock wave therapy can be a choice for recurrent chronic intractable plantar fasci tis. Surgical intervention remains the last line of therapy, for which, rigorous screening is important, but it is not always effective at reducing pain.

Severity Scoring of Atopic Dermatitis in Children: Study for Usefulness of Three Item Severity Score / 소아알레르기및호흡기학회지

PURPOSE: Many different scoring systems have been proposed for assessing the severity of atopic dermatitis. The SCORAD (SCORing Atopic Dermatitis) is one of the best validated systems, but is too complicated and time-consuming for routine clinical use. The aim of this study is to evaluate the Three Item Severity (TIS) score in routine clinical practice and to investigate the correlation with SCORAD and quality of life. METHODS: The study was done on 69 cases of atopic dermatitis randomly selected by SCORAD severity in Kangdong Sacred Heart Hospital pediatric allergy clinic from March 2003 to August 2003. Patients were from three months old to 15 years old. A trained pediatrician assessed the TIS score and simultaneous 10 item questionnaire about quality of life (QOL) was checked. RESULTS: According to the SCORAD, there were 21 (30.4%) mild cases, 26 (37.7%) moderate cases and 22 (31.9%) severe cases out of total 69 patients. According to the TIS score, 21 (30.4%) cases were 0-2 point, 16 (23.2%) were 3 point, 11 (16.0%) were 4-5 point and include 21 (30.3%) were 6-9 point. In QOL score, 21-30 points were most common (36.2%). There was significant positive correlation between TIS score and SCORAD (Spearman's rs= 0.86, P< 0.01). There was significant positive correlation between TIS score and QOL (Spearman's rs=0.89, P< 0.01). CONCLUSION: The TIS score is a reliable and simple scoring system for atopic dermatitis. It is particularly suitable in general practice, for routine clinical use.

To assess the value of X-ray mammography and cytopathology test for breast cancer diagnosis of early stage Tis and T1

Background: Breast cancer is not only the most popular in women but is also one of the main causes of death among them in many countries. In Hanoi 1999, the prevalence of breast cancer was 21.8 per 100,000 of the population and was the main cause of death in women. In Ho Chi Minh city that prevalence was 17.1 per 100,000 of the population and was the second highest cause of death in women. Objectives: To assess the value of X-ray mammography and cytopathology test for breast cancer diagnosis of early stage Tis and T1. Subjects and method: A retrospective study was conducted among 103 breast cancer patients with malignant tumor size \uf0a32cm, who were admitted to K Hospital and Thanh Nhan Hospital from 01/2003 to 02/2008. Results:Breast malignant tumor was usually found most frequently at the upper outer quadrant. Around 86.4% of patients who were suspected with malignant lesion by X-ray mammography. Using biopsy test for breast cancer diagnosis, the results shows that 78.6% of patients were positive, 15.6% of cases were suspected and 5.8% had wrong diagnosis. Pathologic classifications were as followed: invasive lobular carcinoma: 78.6%, intraductal carcinoma in situ (Tis): 4.9%. Conclusion: X-ray mammography and cytopathology test are useful tools for the diagnosis of breast cancer.
