Lower-space, single-contrast arthrography and dual-space, double-contrast arthrotomography were sequentially applied to 58 fresh temporomandibular joint (TMJ) autopsy specimens, and the findings were compared with observations in corresponding cryosections. Both modalities had high accuracy rates (greater than or equal to 84%) and no statistically significant differences between the two techniques were found. A side-by-side comparison of the two types of arthrograms, however, revealed that video tape recording of lower-space, single-contrast arthrography was superior in demonstrating joint dynamics and that dual-space, double-contrast arthrotomography was superior in demonstrating the soft-tissue anatomic features of the joint. It appears that lower-space, single-contrast arthrography can be recommended for examination of patients with clicking, catching, and intermittent locking, and that dual-space, double-contrast arthrotomography is preferable when information about morphologic alterations is clinically more important than information about joint dynamics. 相似文献

A Haitian man with acquired immunodeficiency syndrome (AIDS), fever, malaise, and diarrhea is described. A computed tomographic (CT) scan showed a retrogastric mass with an associated ulcer. An upper gastrointestinal tract study showed an ulcer with both benign and malignant features. Endoscopy revealed a malignant-appearing ulcer, but cultures and histologic examinations of surgical biopsy specimens indicated gastric tuberculosis. The relationship between tuberculosis and AIDS is discussed. 相似文献

Few investigations of the respiratory effects of occupational exposure to tobacco dust have been carried out and the threshold limit value has not well been established. A cross sectional survey on a sample of 223 male and female workers at a cigar and cigarette factory in Lucca (Tuscany) showed a significantly higher prevalence of wheezing, attacks of shortness of breath with wheezing, dyspnoea, and rhinitis than in a reference population. A trend towards a decrease in forced end expiratory flows according to smoking habit and work duration was evident. Positive skin prick tests were observed in 26% of men and 23% of women and were positively associated with duration of work and negatively with cigarette smoking. Thin interstitial space involvement was observed on chest x ray examination in almost half the female workers with more than 35 years exposure. These findings suggest that prolonged exposure to tobacco dust may have negative health effects and that it is advisable to establish a threshold limit value for tobacco dust different from that of inert dust. 相似文献

目前宫颈上皮内瘤样病变(CTV)的治疗主要是根据疾病的性质和范围行局部切除或切除。阴道镜检查出现以前,传统上所有病灶在全麻下都用刀行锥切活检或电凝法行点根治术,而现在更趋向于各种可用于门诊病人的更保守的局部切除和切除治疗。 相似文献

Cinnamon‐flavoured products (toothpaste, chewing gum, food, candy and mouthwash) can cause oral adverse reactions; among these, the most common is contact stomatitis (cinnamon contact stomatitis, CCS). Signs and symptoms of contact allergic reactions affecting the oral mucosa can mimic other common oral disorders, making diagnosis difficult. As CCS may be more prevalent than believed and its clinical features can frequently determine misdiagnosis, we reviewed case reports and case series of oral adverse reactions due to cinnamon‐containing chewing gums, emphasizing clinical aspects, diagnostic and management procedures. We also proposed an algorithm to perform a diagnosis of CCS as in the previous published literature the diagnostic approach was not based on a harmonized and shared evidence‐based procedure. Moreover, as patients can refer to different specialists as dentists, dermatologists and allergists, a multidisciplinary approach is suggested. 相似文献
