脊柱侧凸诊疗问答(九)

先天性脊柱侧凸有哪些治疗措施? 影响先天性脊柱侧凸治疗的因素很多,如病人年龄、性别、畸形部位、侧凸程度、节段长短、畸形类型、可屈性及进展性等.医生应根据不同情况,选择不同治疗手段. (1)非手术治疗:经广泛经验证明,不同于特发性脊柱侧凸,先天性脊柱侧凸病人采用体操疗法、物理疗法、运动疗法、电刺激疗法等无效.Risser石膏矫形治疗:由于石膏沉重,常合并有压疮、胸廓变形、肺功能低下等问题,目前已大多放弃或少用此种疗法.目前在先天性脊柱侧凸非手术治疗中主要是用支具疗法.尽管支具疗法是先天性侧凸非手术治疗主要的或惟一的治疗手段,但不是所有的先天性侧凸都适用于支具治疗.其适应证是有一定限度的,对尚未发育成熟、畸形逐渐加重、侧凸节段长且柔软的病人适应于支具治疗.     

特发性脊柱侧凸的支具治疗

支具治疗是脊柱侧凸非手术治疗的最重要方法之一,其目的主要是阻止骨骼未发育成熟小儿脊柱畸形的进一步发展。尽管支具治疗在临床上已被广泛应用,对其在脊柱侧凸治疗中的作用仍然存在着相当多的争论。本文重点对近年来有关特发性脊柱侧凸支具治疗的研究进展作一简要综述...     

念珠菌与曲霉菌脊柱感染预后影响因素的荟萃分析

1932年,Keating等[1]首次报道脊柱真菌感染,脊柱真菌感染属于系统性感染,复发率和死亡率高于一般细菌感染[2]。近年来,随着免疫缺陷人群的增加,脊柱真菌感染的发生率呈上升趋势,美国的院内感染监测系统显示,真菌感染发生率在过去10年增加了1倍,平均每年发生率约为0.272‰,平均每年增加0.0024‰,年增长率为0.9%[3]。脊柱真菌感染与脊柱结核和布鲁杆菌性脊柱炎同属于肉芽肿性炎,很难在早期鉴别,诊断和检测方法的灵敏度、特异度不高,容易导致诊断延误,影响预后[4]。

A rare post-coronavirus disease 2019 complication of maxillary mucormycotic osteomyelitis in a Southeast Asian patient

Mucormycosis, a rapidly invasive form of fungal infection caused by Mucorales fungi, has high morbidity and mortality rates. Rhino-orbital-cerebral mucormycosis is the most common form of mucormycosis. With the coronavirus disease 2019 (COVID-19) outbreak, a causal correlation between mucormycosis and COVID-19 has been suspected, contributing to the abrupt increase in opportunistic fungal infection cases. We present a case of a Southeast Asian woman in her 60s with complaints of pus discharge in the palatal region with maxillary teeth mobility for 3 months. Physical examination revealed multiple nonvital upper teeth with severe mobility. Incisional biopsy of the maxilla and multidetector computed tomography of the head and neck confirmed the diagnosis of osteomyelitis of the maxilla secondary to mucormycosis. Surgical treatment was performed, and amphotericin B and posaconazole were administered. No operative complications or further bone destruction were observed at 8 months postoperatively.     

Diagnostic pitfalls in osteomyelitis of the odontoid process: case report

BACKGROUND

Pyogenic osteomyelitis of the odontoid process is a very rare disease associated with a variety of clinical symptoms, and previous reports have stressed the difficulties inherent in making the diagnosis. The authors present a case of osteomyelitis of the odontoid process with epidural abscess in which magnetic resonance imaging (MRI) was used in the diagnosis, assessment of the extent of concomitant epidural abscess, treatment effect, and long-term follow-up.

CASE DESCRIPTION

A 68-year-old male was admitted to our hospital with cervical pain, neck stiffness, and fever. Although the diagnosis was missed at the beginning, the patient was diagnosed with osteomyelitis of the odontoid process with a paravertebral epidural abscess by MRI. The patient became asymptomatic after 3 months of antibiotic therapy.

CONCLUSION

Pyogenic osteomyelitis of the odontoid process is a rare condition requiring a high index of suspicion for diagnosis. MRI examination should be considered in the diagnosis in patients with neck pain combined with fever. Serial MRI during and after antibiotic therapy provided an objective assessment of the healing rate of the lesions.     

Salmonella osteomyelitis. An important differential diagnosis of granulomatous osteomyelitis

A case of septicemia owing to Salmonella choleraesuis with localization in the lumbar spine and left knee is described. The spinal lesion is dominated by tuberculoid granulomas with or without central necrosis. The necrotic foci within some granulomas show heavy polymorph infiltration, whereas in others they simulate caseous necrosis and are indistinguishable histologically from tuberculosis, brucellosis, and fungal infections. As Salmonella osteomyelitis has a strong tendency to chronicity if antimicrobial treatment is delayed, inappropriate, or inadequate, this diagnosis should be considered in all cases of granulomatous osteomyelitis, especially when the patient is immunosuppressed or has hemoglobinopathy.     

Pyogenic vertebral osteomyelitis: report of a series of 23 patients

Vertebral osteomyelitis, an infectious disease with vague manifestations, can be difficult to diagnose. Although vertebral osteomyelitis represents only 2-4% of bone infections, the consequences are often grave and disabling, even fatal, when untreated. A series of 23 cases is reported in which patient records were reviewed to determine the etiology and appropriateness of diagnosis and management. Information on treatment and follow-up after discharge was obtained from outpatient progress notes, records from subsequent hospital admissions, and telephone interviews of patients. Pyogenic vertebral osteomyelitis was diagnosed by positive needle or open biopsy tissue cultures, positive blood cultures in the appropriate clinical setting, or diagnostic histopathology. Staphylococcus aureus was grown from 75% (15/20) of patient cultures, Escherichia coli from 15%, and Staphylococcus epidermidis from 10%. Overall, 87% (20/23) of these patients were disease-free at follow-up. The experience with this series of patients demonstrates that early diagnosis aided by MRI ensures a high cure rate and low complication rate.

目的 分析非典型骨髓炎的影像学表现探讨诊疗方法.方法观察24例非典型骨髓炎患者影像学表现,并与手术病理结果进行对照.结果 24例患者术后病理均证实为骨髓炎.显示软组织肿胀:X线平片10例,CT 18例,MRI 21例;显示骨膜反应:X线平片15例,CT 18例,MRI未见;显示骨髓腔密度增高:X线平片11例,CT 16例,MRI 24例;显示骨皮质增厚:X线平片10例,CT 14例,MRI 18例.结论 MRI对非典型骨髓炎的早期诊断、鉴别诊断帮助较大,X 线平片仍是基础.X线平片、CT结合MR检查是非典型骨髓炎的早期诊断和鉴别诊断的重要手段.非典型慢性骨髓炎影像学表现不典型,误诊、漏诊率较高,认识其临床及影像学表现可以提高诊疗水平.     

Critically evaluating the role of diagnostic imaging in osteomyelitis

Early diagnosis, essential for timely appropriate treatment and reduction of complications, can be difficult. This article aims to give an overview of the role that different imaging modalities have to play in the diagnosis of osteomyelitis. Osteomyelitis is a heterogeneous disease in its pathophysiology, clinical presentation, and management. It infers inflammation of bone and marrow, whereas osteitis is inflammation of the bone only. Thus, a soft-tissue infection that reaches the bone surface but has not infected the marrow is osteitis and not osteomyelitis. Chronic osteomyelitis is divided into active and inactive forms. Newly appearing periosteal reaction or bone destruction within the chronic involucrum are indicators of activation. Imaging modalities represent different underlying pathophysiological processes that may be represented in differing types and differing phases of osteomyelitis. Sequential selection of appropriate imaging modalities requires a thorough understanding of the disease processes and the process by which each modality visualizes this dynamic disease process.

Diagnostic errors in hematogenic osteomyelitis of the pelvic bones

The authors have analysed the caused of frequent diagnostic errors in the primary diagnosis which reach 51.2% in 41 patients with hematogenic osteomyelitis of the pelvis. A high percentage of diagnostic errors is caused by more frequent occurrence of hematogenic osteomyelitis of the pelvis in the adults aged 20 to 60 and older who are "not expected" to have hematogenic osteomyelitis which is considered to be a disease characteristic of children and adolescents, by an inadequacy between the provoking etiologic factor and the subsequent development of the disease and by disguise of hematogenic osteomyelitis of the pelvis with symptoms of other frequently occurring diseases. The character of the diagnostic errors is clearly linked with the localization of the process in the bones of the pelvis.     

Fungal postoperative spondylodiscitis due to Scedosporium prolificans

Background contextPostoperative fungal spondylodiscitis is a rare infectious disease.PurposeWe report the first case of postoperative spondylodiscitis because of Scedosporium prolificans and review postoperative vertebral infection caused by fungi.Study design/settingMedline search.MethodsCase report and literature review.ResultsOn reviewing the cases of postoperative fungal spondylodiscitis reported so far in the literature, we found eight were caused by mold, and five by yeast. Clinically, the disease presents similar to postoperative vertebral osteomyelitis caused by bacteria, and a high clinical index of suspicion may be required to perform appropriate cultures to establish a diagnosis. Our review revealed a significant number of cases that were cured after surgical debridement and/or antifungal therapy.ConclusionsOn the basis of this limited assessment, it appears that the clinical course and prognosis of postoperative fungal spondylodiscitis is similar to that reported for postoperative pyogenic spondylodiscitis.     

Cutaneous botryomycosis of the cervicofacial region

BACKGROUND: Botryomycosis is a rare, chronic, bacterial infection of insidious onset involving the integument or viscera that often mimics actinomycosis or a deep fungal infection. The pathogenesis is thought to be a symbiotic relationship between the host and the infecting organism. METHODS: Case report of a patient with a chronic infection involving the cervicofacial region diagnosed as cutaneous botryomycosis arising from a chronic osteomyelitis of the mandible. The diagnosis was based on the chronicity of the infection along with the identification of botryomycotic (bacteria-containing) granules on histopathologic examination. Special stains excluded fungi and mycobacterium. Cultures identified the offending bacteria, and antibiotic therapy was initiated on the basis of the sensitivities, resulting in resolution of this chronic infectious process. A review of the English language literature revealed that this is the first case of cutaneous botryomycosis arising from a chronic osteomyelitis of the mandible. RESULTS: Medical therapy proved curative at 14 months follow-up. Surgery was performed for diagnostic purposes only. CONCLUSIONS: Botryomycosis is exceedingly rare in the head and neck, and consideration of this entity in the differential diagnosis is critical to the diagnosis. The mainstay of therapy is medical with surgery reserved for biopsy and/or excision of persistent disease. Published 2001 John Wiley & Sons, Inc.
