The etiology of spontaneous hemarthrosis of the knee joint in elderly pattents is still unknown. This report discusses seven spontaneous hernarthroses, three that were managed witla conservative measures such as aspiration, rest and knee immobilization because of poor general condition and four in which arthroscopic evaluation and treatment were performed. These patients were elderly indi.viduals without an obvious history of trauma. The roentgenograms of each involved knee demonstrated degenerative osteoarthritic changes of knee joint. Arthroscopic examination revealed denuded articular cartilage and subchondral bone exposure in four operative cases and degenerative meniscal tear in one case of four. These patients underwent mthroscopic debridement and did not experience recurrenees of the hemarthrosis. We think that the origin of the bleeding was most likely from the subchondral cancellous bone which was exposed due to degenerative change of the knee joint and the senile changes of the vessels around the knee joint with aging process may contribute the spontaneous bleeding into the knee joints.

Congenital absence of nails usually occur as a rare isolated anomaly or combined with other ectodermal defects. This anomaly is regarded as an inherited disorder either dominantly or recessively but quite a few cases were reported as sporadically developed. The patient was a 2-month-old girl who had no nails on both her 2nd, 3rd toes but had rudimentary nails on her left big toe and both 4th toes at birth. We could not find any other congenital deformity, any family history of inherited diseases related to anonychia. Radiological findings revealed no visualization of both 4th distal phalanges, only. We report this case as congenital anonychia of a sporadic type which may have developed independently from an underlying bone abnormality. We also review other reported cases in the literature.

Lichen planopilaris is believed to be a variant of lichen planus which is occasionally accompanied by classical lichen planus. A 68-year old male had asymptomatic skin colored or light violet colored papules and nodules on the occipital area followed by hair loss for 2 months. He had also violaceous pea to bean sized whitish scaly papules on the right lower extremity. Histopathological examination revealed the dilated follicles to be filled with horny material. There were also intense infiltrations of monocytes which were most prominent at the lower pole of the hair follicles on the scalp lesion. There was also hyperkeratosis, focal hypergranulosis and band-like infiltrations of lymphocytes at the dermo-epidermal junction on the lesion of the lower extremity. Direct immunofluorescence examination showed linear deposition of fibrin at the dermo-epidermal junction in the hair follicles. We had an opportunity to observe a man with lichen planopilaris who had loss of scalp hair which was accompanied by classical lichen planus on the lower extremity.

Parathyroid hormone (PTH) has not been studied as extensively as therapeutic agents of osteoporosis, but the anabolic effect of parathyroid hormone on the skeleton has been demonstrated in several studies. The current study was undertaken to assess the effect of parathyroid hormone on bone mass and its biomechanical competence using ovariectomized rat model. Fifty female Sprague Dawley rats of 3 months old were randomized into five groups, 10 in number for each groups. Group I: sham-operation, Group II: ovariectomy (OVX) plus saline injection, Group III: OVX plus PTH 20ug/kg, Group IV: OVX plus PTH 40ug/kg, Group V: OVX plus PTH 80ug/kg. Treatment regimens were initiated 8 weeks after ovariectomy and continued for 4 weeks thereafter. Bone mineral density was measured in proximal one-third level of tibia by dual energy X-ray absorptiometry (QDR-2000, Hologic, U.S.A). Biomechanical competence was assessed in lumbar vertebral body by universal testing machine (Instron-4467, U.S.A). The average of bone mineral density in sham operated group was 0.088+/-0.0084g/cm (2), and in control group (OVX +/- saline)was 0.065+/-0.0095g/cm (2). Bone mineral density decreased in control group significantly. The average of bone mineral densities in Group III, IV, V (OVX + PTH) were 0.071+/- 0.0089, 0.081+/-0.0086 and 0.084+/-0.0093g/cm (2), respectively. This showed that parathyroid hormone injected groups had significantly higher bone mass than control group (p<0.0#5), and the increment was in proportion to the amount of parathyroid hormone in the range (p<0.05). The average of biomechanical competence of lumbar vertebral body in sham operated group was 30.036.24 MPa and was 25.11+/-5.69 MPa in control group. In Group III, IV,V they were 25.74+/-6.77, 27.96+/-5.17 and 29.83+/-5.79 MPa, respectively. Above results seem supportive of the phenomenon that parathyroid hormone exert anabolic effect on osteoporotic bones in certain experimental condition.

Recently MRI has been shown to be a sensitive and specific study for the noninvasive detection of meniscal tears and several MRI findings of bucket-handle meniscal tears have been reported. Therefore, the MRI findings of the menisci proven to be the bucket-handle tear with arthroscopy were evaluated and the typical MRI findings seen to be the bucket-handle meniscal tear of the knee were analysed. 76 patients with proven bucket-handle meniscal tears arthroscopically were reviewed retrospectively, in which MRI was performed in 24 patients. The 3 typical findings of bucket-handle meniscal tears were assessed: double PCL (posterior cruciate ligament) sign, flipped meniscus sign, and fragment in the intercondylar notch. In 245 cases of meniscus tears, bucket-handle meniscal tears were 76 cases (31.0%) with 52 cases at medial meniscus and 24 cases at lateral meniscus. As to clinical and physical findings of the bucket-handle meniscal tears, McMurray test, locking, joint line tenderness and giving way sense were presented in orders. The sites of bucket-handle meniscal tear were medial meniscus in 17 cases and lateral in 7 cases. The double PCL sign was seen in 10 cases (58.8%) of in medial bucket-handle meniscal tears and in 3 cases (42.9%) of 7 lateral bucket-handle meniscal tears. The flipped meniscus sign were seen in 3 cases (17.6%) of medial bucket-handle meniscal tears and in 3 cases (42.9 %) of lateral bucket-handle meniscal tears. Fragments were identified in the intercondylar notch in 8 cases (47.1%) of medial bucket-handle meniscal tears and in 3 cases (42.9%) of lateral bucket-handle meniscal tears. There were 19 cases (79.2%) in which at least one or more typical findings were presented on MR images. The MRI is a sensitive study for detection of bucket-handle meniscal tears but precise interpretation of MRI is needed for diagnosis of bucket-handle tears. In this respect, the above three typical findings are helpful and reproducible for diagnosis of bucket-handle meniscal tears with MR images; double PCL sign, fragment in the intercondylar notch and flipped meniscus sign.
