Chronic recurrent multifocal osteomyelitis and psoriasis—A report of a new association and review of related disorders

In summary, we have described two patients with CRMO and psoriasis, and have reviewed the musculoskeletal manifestations associated with pustular eruptions of the palms and soles. In view of the frequent occurrence of PPP in patients with CRMO, we suggest that the occurrence of psoriasis in our two patients is more than coincidence, and that noninfectious, inflammatory lesions of bone may be another musculoskeletal manifestation of psoriasis. This rare association, as well as the association of PPP with disorders associated with new bone formation, may shed new insights on the relatively common finding of periosteal elevation associated with psoriatic arthritis and the occasional severe juxta-articular osteolytic destructive bone lesions seen in psoriatic arthritis.     

Capsaicin cough sensitivity in allergic asthmatic patients increases during the birch pollen season.

BACKGROUND: A change in neural responsiveness may occur as the result of allergic inflammation in the lower airways as well as in the upper airways. In the lower airways, capsaicin cough sensitivity is known to reflect sensory neural reactivity. OBJECTIVE: The aim of this study was to establish whether allergic inflammation changes airway neural sensory reactivity during prolonged allergen exposure. METHODS: Ten nonsmoking patients with birch pollen-allergic asthma performed a capsaicin inhalation challenge twice, once in the off-pollen season and once during the pollen season. The number of coughs and symptoms induced by capsaicin were recorded and compared with those of healthy control subjects. RESULTS: The response to capsaicin, expressed as number of coughs, increased in a dose-dependent manner during both tests. Before the season, the response was similar to that of healthy control subjects, but during the pollen season, the reactivity was significantly increased. Variations in forced expiratory volume in 1 second were not significant before and after each challenge, and values did not change during the pollen season as compared with the winter season. CONCLUSIONS: Sensory reactivity in allergic asthmatic patients may be increased during prolonged allergen exposure as during the pollen season. This finding suggests that allergic inflammation in the lower and/or upper airways may trigger neurogenic mechanisms of significant clinical importance.

Effect of exercise on repetitive nerve stimulation studies: new appraisal of an old technique.

Repetitive nerve stimulation (RNS) is a simple and rapid method for evaluation of neuromuscular transmission defects. Although the effect of exercise in conjunction with RNS is well recognized, it has not been standardized in actual patient and control groups. In a prospective study over a period of 1 year, the authors evaluated the effect of exercise in conjunction with RNS in comparison with conventional 3-Hz RNS at rest in the clinical setting. Fifty-four patients who were referred for possible neuromuscular transmission disorders, in addition to 35 healthy control subjects, were studied. Amplitude and area decremental responses with RNS at rest and after 20 seconds of maximal exercise at 1-minute intervals up to 3 minutes were evaluated. The use of RNS with exercise resulted in additional diagnostic yield of up to 36.4% compared with conventional 3-Hz RNS at rest. The standardized use of exercise with RNS is advocated for increasing its diagnostic yield in the neurophysiologic laboratory.     

肝纤维化组织中MMP1、TIMP1的表达及其临床意义

目的 :检测肝纤维化组织中基质金属蛋白酶 1 (MMP1 )、基质金属蛋白酶组织抑制因子 1 (TIMP1 )的表达 ,为肝纤维化的诊治提供重要的分子生物学指标。 方法 :采用链霉菌抗生物蛋白 -过氧化酶联接法 (S- P法 )检测70例肝纤维化组织中 MMP1 、TIMP1 的表达。结果:(1) TIMP1 蛋白阳性表达随肝纤维化程度的加重而增强 ,并且呈正相关关系 (r=0 .92 74 ,P <0 .0 1)。 (2 ) MMP1 蛋白阳性表达随肝纤维化程度的加重无明显变化 ,无相关关系(r =0 .2 181,P >0 .0 5 )。 结论:TIMP1 与肝纤维化的发生、发展密切相关 ,随纤维化发生、发展阳性表达增强。从分子水平对肝纤维化、肝硬化病变进行评估 ,为早期诊治肝纤维化和判断预后提供依据。     

隐性脊柱裂排尿功能异常的临床特征

目的：研究伴有排尿功能障碍的隐性脊柱裂患者临床特征。方法：总结41例有明显排尿功能障碍的隐性脊柱裂患者临床资料。以18岁为界，将患者分为儿童组和成人组，所有患者均接受X线检查，除4例儿童外，均接受普通尿流动力学检查。结果：儿童组发病高峰年龄在1～2岁，主要临床表现为持续性原发性遗尿，部分伴有尿频、尿急及轻度急迫性尿失禁现象；成人组发病高峰年龄在18～26岁，主要临床表现为尿频、尿急、排尿前踌躇、排尿困难、遗尿等。结论：隐性脊柱裂患者常有排尿功能异常表现，出现症状的高峰时间为出生后及青春发育期后。X线、CT、MRI和尿流动力学等检查在隐性脊柱裂排尿功能障碍的诊断和治疗方案制定中有重要地位。     

正畸固定矫治前后牙齿冷光美白疗效的对比研究

目的:了解经固定矫治的正畸患者在牙齿美白治疗后牙齿表面中部出现较规则斑块的成因。方法:分别对正畸及非正畸治疗患者、正畸治疗前后拔除的离体牙进行牙齿美白治疗,对牙列组进行视觉对比,对离体牙组进行扫描电镜对比。结果:经正畸治疗的牙列在美白治疗后牙面有色斑存在,而正畸治疗后拔除的离体牙的扫描电镜结果则显示有釉质-树脂突嵌合层存在。结论:经正畸治疗后牙齿表层的釉质-树脂突嵌合层是导致牙面出现色斑的原因。
