Tuberculosis involving the soft tissue from adjacent bone or joint is well recognized. However, primary tuberculous pyomyositis, tuberculous bursitis, and tuberculous tenosynovitis are rare entities constituting 1% of skeletal tuberculosis. Tuberculous tenosynovitis involves most commonly the tendon sheaths of the hand and wrist, and tuberculous bursitis occurs most commonly around the hip. The greater trochanteric bursa and the greater trochanter are the most frequent sites of tuberculous bursitis. Cases of primary tuberculous pyomyositis and tenosynovitis of the tendons of the ankle and foot are seldom reported in the radiology literature. All imaging modalities-plain radiography, bone scan, computed tomography, and magnetic resonance imaging (MRI)--provide information that is helpful in determining therapy. MRI in particular, with its multiplanar capabilities and superb contrast of soft tissue, can demonstrate the extent of the soft tissue mass and access the adjacent bones and joints. However, MRI has no diagnostic specificity in regard to tuberculosis, and in nonendemic areas, biopsy is strongly recommended. All patients in this review were permanent residents of North America or Western Europe and were immunocompetent. Examples of atypical presentations of the above entities are demonstrated. 相似文献

Altered cortisol levels in relation to Ramadan 总被引:1,自引:0,他引:1
During the month of Muslim fasting (Ramadan) many people alter their sleeping habits and stay awake most of the night. We investigated the effect of this alteration on morning and midnight cortisol levels in 10 healthy adults in their homes. Four of the subjects showed alteration of the cortisol rhythm during the last 2 weeks of fasting with reversal of the morning/midnight ratio in some values. One lady was admitted for 24-h cortisol profile on Day 15 of Ramadan when the acrophase and nadir showed a forward shift by about 5-6 h, consistent with the shift of the subject's sleep. The morning cortisol returned to normal in all subjects 4 weeks after Ramadan. However, the midnight value was above 250 nmol/l in three of the subjects who exhibited the alteration during Ramadan. These findings suggest that single-point cortisol values can be misleading in many Muslin countries during or shortly after Ramadan. 相似文献

The clinical entity of Tietze's syndrome is well known. It is benign in nature, self-limiting, and of unknown etiology. Computed tomography has proved most helpful in the initial evaluation of this disorder, especially as roentgenographic plain films have been essentially noncontributory in the past. A case of this disorder was followed up over the course of 2 months, and the clinical and computed tomography findings were correlated. The authors believe that computed tomography is the most exact and reliable modality for the follow-up evaluation of patients with Tietze's syndrome. 相似文献

Chlamydial etiology of acute lower respiratory tract infections in children in the Sudan 总被引:2,自引:0,他引:2

The role of Chlamydia pneumoniae in 110 Sudanese children with signs of acute lower respiratory tract infections (ALRI) was investigated. Four (3.6%) had evidence of C. pneumoniae infection, of whom 3 were culture-positive, while 1 had an antibody response suggesting a recent infection. IgG antibodies at a titer of ≥1:32 to C. pneumoniae, Chlamydia psittaci and Chlamydia trachomatis were detected in 27 (24.5%), 27 (24.5%) and 7 (6.4%) of the 110 ALRI cases, respectively. C. pneumoniae, C. trachomatis or C. psittaci were not detected in nasopharyngeal secretions from any of 110 patients when fluorescence-labeled specific monoclonal antibodies were used. In a seroepidemiological survey, 318 healthy Sudanese persons aged between 1 month and 67 years were studied for C. pneumoniae antibodies. 相似文献

High-frequency ultrasound (US) is an efficient, rapid and inexpensive altenative to magnetic resonance imaging (MRI) for investigation
of diseases in the soft tissues of the wrist and hand. US allows detection of foreign bodies and the reliable identification
of a variety of traumatic lesions affecting tendons, annular pulleys, ligaments, vessels and nerves. Inflammatory diseases
of tendons, including acute and chronic tenosynovitis and some degenerative conditions in the wrist and hand, can also be
diagnosed. In entrapment neuropathies, US is able to identify nerve shape changes and possible extrinsic space-occupying lesions
that may cause nerve compression within the tunnels. In patients with localized swelling of the hand or wrist, US is able
to assess the presence of an expansile lesion and to characterize its nature in most cases. The objective of this article
is to review the main findings and the primary indications of US in the investigation of disorders of the hand and wrist.
