Proteus syndrome is a rare, sporadic, hamartomatous disorder manifesting with multifocal overgrowth of tissue. The features seem to develop most often during childhood. Vertebral overgrowth with severe spinal canal stenosis is unusual, although scoliosis with abnormal vertebral bodies is one of the typical features of Proteus syndrome. We report a case of Proteus syndrome with severe spinal canal stenosis, scoliosis, cervical kyphosis, and thoracic deformity with airway obstruction because of asymmetrical overgrowth of vertebrae and ribs associated with a tethered cord, lipomas, strawberry hemangioma, flat nasal bridge, and bilateral hypoplasty of the first metatarsal bones with hyperplasty of soft tissue. 相似文献

This study aimed to analyze and classify the clinical features of headache in neurological outpatients. A cross-sectional
study was conducted consecutively from March to May 2010 for headache among general neurological outpatients attending the
First Affiliated Hospital of Chongqing Medical University. Personal interviews were carried out and a questionnaire was used
to collect medical records. Diagnosis of headache was according to the International classification of headache disorders,
2nd edition (ICHD-II). Headache patients accounted for 19.5% of the general neurology clinic outpatients. A total of 843 (50.1%)
patients were defined as having primary headache, 454 (27%) secondary headache, and 386 (23%) headache not otherwise specified
(headache NOS). For primary headache, 401 (23.8%) had migraine, 399 (23.7%) tension-type headache (TTH), 8 (0.5%) cluster
headache and 35 (2.1%) other headache types. Overall, migraine patients suffered (1) more severe headache intensity, (2) longer
than 6 years of headache history and (3) more common analgesic medications use than TTH ones (p < 0.001).TTH patients had more frequent episodes of headaches than migraine patients, and typically headache frequency exceeded
15 days/month (p < 0.001); 22.8% of primary headache patients were defined as chronic daily headache. Almost 20% of outpatient visits to the
general neurology department were of headache patients, predominantly primary headache of migraine and TTH. In outpatient
headaches, more attention should be given to headache intensity and duration of headache history for migraine patients, while
more attention to headache frequency should be given for the TTH ones. 相似文献

Castleman disease (CD) is a rare lymphoproliferative disorder. Two clinical entities are described: a unicentric form with disease confined to a single lymph node region and a multicentric form characterized by generalized lymphadenopathy and systemic symptoms. Although surgery is regarded as standard therapy for the unicentric form, no consensus has been reached concerning the standard treatment for multicentric CD. We report here a case of cervical multicentric CD treated with intensity-modulated radiation therapy (IMRT), using helical tomotherapy to minimize xerostomia in comparison with conventional radiotherapy. A 29-year-old woman complained of neck swelling. Computed tomography showed lymphadenopathy in both sides of the neck. The patient was diagnosed with the plasma cell subtype of CD on biopsy. After initial treatment with prednisone, IMRT was planned to avoid normal structures, for example the parotid gland. The cervical lymphadenopathy shrank gradually during IMRT with 44 Gy in 22 fractions. Four years and 3 months after IMRT, regrowth of cervical lymph nodes has not been detected. The parotid function improved dramatically on quantitative salivary scintigraphy between 3 and 12 months after IMRT. Radiotherapy could be an option for multicentric CD, and IMRT is an effective means of minimizing xerostomia in head and neck lesions. 相似文献

This case report involves a 60-year-old diabetic man who developed septic arthritis as a result of the pathogen Morganella morganii. The patient had complaints of elevated body temperature, malaise, rigors and pain in the left knee, despite no history of
trauma. On examination of the knee, erythema, warmth, tenderness and swelling was observed. Arthrocentesis performed on his
left knee indicated the presence of straw-coloured, cloudy fluid without crystals. Bacterial identification based on biochemical
and automated methods indicated the growth of M morganii. M morganii was also isolated sedimentafrom the exudate of a diabetic ulcer in the left foot, with antibiotic susceptibilities identical
to those from the knee effusion. This case indicates that M morganii may be considered as a possible cause of septic arthritis in diabetic patients, especially those with diabetic foot infections. 相似文献

Positron emission tomography (PET) using l-[methyl-11C]-methionine (MET) is the most popular amino acid imaging modality in oncology, although its use is restricted to PET centers
with an in-house cyclotron facility. This review focuses on the role of MET–PET in imaging of cerebral gliomas. The biological
background of tumor imaging with methionine is discussed with particular emphasis on cellular amino acid transport, amino
acid utilization in brain, normal metabolism of methionine, and its alterations in cancer. The role of MET–PET in clinical
management of cerebral gliomas in initial diagnosis, differentiation of tumor recurrence from radiation injury, grading, prognostication,
tumor-extent delineation, biopsy planning, surgical resection and radiotherapy planning, and assessment of response to therapy
is also reviewed in detail. 相似文献

Purpose
The aim of this study was to elucidate the distribution of estimated glomerular filtration rate (eGFR) values in patients who underwent gadolinium-based contrast agent (GBCA)-enhanced magnetic resonance imaging (MRI) at different types of hospitals.Materials and methods
We retrospectively studied 2,550 patients who underwent MRI at five institutions. We recorded the date and value of each patient??s eGFR test. The distribution of eGFR values was compared with that in the general Japanese population.Results
A total of 84.3% of patients had their eGFRs evaluated before GBCA-enhanced MRI. Of these, 84.7% were evaluated within 3?months before the GBCA-enhanced MRI, and 1.3% were evaluated on the day of the GBCA-enhanced MRI. A total of 87.2% of patients tested had an eGFR of ??60?ml/min/1.73?m2; 12.8% had an eGFR of <60 and ??30?ml/min/1.73?m2, and no patients had an eGFR of <30?ml/min/1.73?m2.Conclusion
The rate of renal function evaluation differed among hospitals. The prevalence of low eGFR values was greater in Juntendo Tokyo Koto Geriatric Medical Center than in the other hospitals, and the prevalence of low eGFR values was greater in patients who underwent GBCA-enhanced MRI than in the general Japanese population. 相似文献1000.

Patients with coronary artery calcium (CAC) scores of zero are generally considered not to have atherosclerosis. Recent studies
involving computed tomography coronary angiography (CTCA) challenge this assumption. This goal of the present study is to
assess the frequency, morphology, location, and the prognosis of patients with plaque detected on CTCA and zero CAC. 1,119
patients (51 ± 12 years, 52% male) with a zero CAC score during CTCA study were retrospectively identified. The CTCA studies
were assessed for the presence, morphology, location and severity of all coronary plaques. All-cause mortality was assessed.
The prevalence of coronary plaque was 13% (147 patients). Among the 212 plaques identified 154 (73%) were non-calcified, 28
(13%) were calcified, and 30 (14%) were of mixed morphology. Notably, ≥70% stenosis was noted among only 0.4% of all patients.
ROC analysis revealed that coronary artery disease risk factors did not add to the prediction of plaque among our patients.
Over a mean follow-up of 2.5 ± 0.6 years there were 4 deaths (0.4%), all in patients without coronary plaque on CTCA. The
presence of coronary plaque is not uncommon among patients with zero CAC scores. These plaques were rarely associated with
hemodynamically significant stenoses and were associated with an excellent prognosis. Clinical factors do not appear to be
useful in predicting which patients with zero CAC scores have undetected coronary plaque. 相似文献
