Melorheostosis is a rare disease entity of bone with an etiology and pathogenesis. It cause pain and stiffness in an affected limb, and dense bone formation along the side of bone resembles the flow of candle dripping. Two cases of the disease involving left hand and wrist, and right lower leg are reported with the review of literature.

PURPOSE: This study was performed to evaluate clinical manifestations and findings of ultrasonogram of neonatal septic arthritis and osteomyelitis. We tried to determine the value of ultrasonogram as a tool for early diagnosis of septic arthritis and osteomyelitis. METHODS: We reviewed the records of 17 patients, who were diagnosed septic arthritis and/or osteomyelitis in Departments of Pediatrics and Orthopedic Surgery, Han dong University Sunlin Hospital in Pohang between Jan. 1994 and Sep. 1998. Radiologic findings were reviewed retrospectively according to the duration of symptoms at the onset. We compared the sensitivity of ultrasonogram with other radiologic tools done within 7 days of illness. RESULTS: We compared sensitivity of each imaging study done within 7 days of illness. 20%(3/5) had abnormality in plain radiographs, 78.6%(11/14) in ultrasonogram, 28.6%(2/7) in bone scan, and 100,0%(3/3) in MRI. Deep soft-tissue swelling around the bone was the earliest sign of acute osteomyelitis in ultrasonogram. Concurrently early septic arthritis showed deep soft tissue swelling around the joint and increased synovial effusion in ultrasonogram. CONCLUSION: Ultrasonogram is not so expensive, non-invasive, not harmful to patients, and there is no need to sedate patients for examination. Comparing with other imaging studies, the sensitivity of ultrasonogram is relatively high. Ultrasonogram is a useful diagnostic tool of septic arthritis and osteomyelitis in newbom infants.

BACKGROUND AND PURPOSE: Visual assessment of medial temporal-lobe atrophy (MTA) has been quick, reliable, and easy to apply in routine clinical practice. However, one of the limitations in visual assessments of MTA is the lack of widely accepted age-adjusted norms and cutoff scores for MTA for a diagnosis of Alzheimer's disease (AD). This study aimed to determine the optimal cutoff score on a T1-weighted axial MTA Visual Rating Scale (VRS) for differentiating patients with AD from cognitively normal elderly people. METHODS: The 3,430 recruited subjects comprising 1,427 with no cognitive impairment (NC) and 2003 AD patients were divided into age ranges of 50–59, 60–69, 70–79, and 80–89 years. Of these, 446 participants (218 in the NC group and 228 in the AD group) were chosen by random sampling for inclusion in this study. Each decade age group included 57 individuals, with the exception of 47 subjects being included in the 80- to 89-year NC group. The scores on the T1-weighted axial MTA VRS were graded by two neurologists. The cutoff values were evaluated from the area under the receiver operating characteristic curve. RESULTS: The optimal axial MTA VRS cutoff score from discriminating AD from NC increased with age: it was ≥as ≥1, ≥2, and ≥3 in subjects aged 50–59, 60–69, 70–79, and 80–89 years, respectively (all p < 0.001). CONCLUSIONS: These results show that the optimal cutoff score on the axial MTA VRS for diagnosing of AD differed according to the decade age group. This information could be of practical usefulness in the clinical setting.
