Infantile osteopetrosis is a rare congenital disorder caused by abnormal bone resorption. Patients with osteopetrosis can have severe anemia, thrombocytopenia, hepatosplenomegaly, rickets, visual impairment, and deafness. Cytomegalovirus also can cause a congenital infection with anemia, thrombocytopenia, hepatosplenomegaly, and calcifications in the brain. We report a 38-day-old infant with severe hepatosplenomegaly, thrombocytopenia, hypocalcemia, and growth failure. Real time polymerase chain reaction detected cytomegalovirus in the plasma. Skeletal radiography revealed generalized bone sclerosis. He was diagnosed with osteopetrosis along with cytomegalovirus infection. Only the test for mutation of the CLCN7 gene, representing the most common and heterogeneous form of osteopetrosis, was available, and the result was negative. With supportive care and antiviral treatment, severe thrombocytopenia due to the cytomegalovirus infection almost normalized despite the possible immunosuppression caused by osteopetrosis. We present the first report of an infant who suffered from osteopetrosis and CMV infection which was successfully treated by long term antiviral agent therapy.

Fibrous dysplasia is a benign pathologic condition in which the normal cancellous bone is replaced by the fibro-osseous tissue. It is found mostly in the femur, tibia, skull, rib, and humerus. Clinically it may develops pain, progressive deformity, and pathologic fracture. Curettage with bone graft has been the most popular treatment method thesedays. A 17-year-old female who had fibrous dysplasia of the humerus combined with multiple cystic lesion was treated by intralesional steroid injection into the lesion total 2 times. The follow-up plain X-ray which was taken 11 months after steroid injection reveals decrease in size and increase in bone density and cortex thickness. The follow-up MRI reveals significant decrease in size and signal intensity. The signal intensity was decreased to that of normal bone marrow in T2 weighted image. She complains no pain and lives symptom free in last follow-up at 2 years and 8 months after steroid injection.

Renal osteodystrophy(RO) is characterized by skeletal changes in patients with renal disease and developed as a result of alterations in the metabolism of calcium, phosphate and secondary hyperparathyroidism. Bony changes in the craniofacial region include decreased bone density, radiolucent lesions(brown tumors), depletion of cortical bone and loss of lamina dura, but such changes rarely occur in the temporomandibular joint(TMJ). We report an uncommon case of bony changes and pain of both TMJs in a patient with RO. A 41-year-old man with RO came to our clinic due to TMJ pain and sounds. Occlusal change was also reported. Radiographs revealed degenerative changes of the both condyles. The patient had medical history of renal cancer therapy and hemodialysis. The patient was diagnosed with TMJ arthritis of RO and referred for systemic management through medication of calcium and vitamin D and parathyroidectomy. At 15-month follow-up, most of TMD symptoms disappeared and second radiographs revealed that bone density and cortical thickness of the mandible increased and the skeletal outline of the both condyles became relatively clear. As bony changes may begin in the early stage of the renal disease, dentists should be alert to detect the sign of the disease. In addition, it is important to differentiate TMJ arthritis of systemic cause because the treatment protocol is quite different.

Cyclic neutropenia is a hematologic disorder characterized by a marked decrease in the number of circulating neutrophils occurring at regular intervals and after this period, the level of neutrophils usually recovers to a normal range. The clinical symptoms of cyclic neutropenia include fever, malaise, headaches and oral findings associated with painful soft tissue ulceration where lips, tongue and gingiva are typically involved. A 4 year 1 month old boy was presented to the hospital. His chief complaint was mobility of his teeth and swollen gums. The patient had suffered from cyclic neutropenia. Clinical examination revealed evident decay on all primary teeth except for the mandibular anterior teeth and localized alveolar bone loss around mandibullar right and left first primary molars which have mobility was notable. The patient was diagnosed with multiple dental caries, gingivitis and localized periodontitis associated with cyclic neutropenia and treated based on it. The dental treatment, including regular tooth care and appropriate treatment of dental caries or gingivitis, is essential for patients suffering cyclic neutropenia. Especially, proper care at an early stage is needed for young patients to minimize the unwanted consequences for permanent teeth development.

Osteopetrosis is characterized by impaired osteoclast function and increased bone density. Infantile osteopetrosis is a severe form of the disease and has characteristics such as diffusely sclerotic skeleton, pancytopenia, cranial nerve entrapment, infection susceptibility, and abnormal craniofacial appearance. Patients with infantile osteopetrosis often experience developmental delay, and may have a short life span. A 14-month-old girl with osteopetrosis presented to the department of pediatric dentistry. Incipient caries on deciduous incisors were observed. The patient revisited 4 years of age. Besides medical problems, oral complications such as growth retardation, narrow upper arch, crowding, dental caries, and abnormal tooth development were observed. After consultation with her pediatrician, dental treatments were performed on the deciduous molars under sedation after a prophylactic antibiotic injection. At a periodic follow-up, multiple deciduous teeth were treated and extracted, and oralrehabilitation with a removable partial denture was initiated. Patient with osteopetrosis are highly susceptible to infection because of their compromised immune system and problems associated with wound healing that lead to osteomyelitis or sepsis development. Active participation in dental care for sugar intake management and proper oral hygiene are obligatory.

In this study, we investigated the preventive and therapeutic effects of antler-extract for osteoporosis. Rats were ovariectomized bilaterally and were fed up with Ca- and P-free diet in order to induce osteoporosis. Body weight, organ weight, the weight of femur and bone ash quantity were examined for 5 weeks. We also performed histological and electronical microscopic examinations. 1. After adminstration of female and male antler extract to osteoporosis-induced rats at the doses of 625 and 1250 mg/kg, respectively, the body weights were significantly increased compared with those of normal control group's which was 230.2:t2.3-281.0:t2.5g (p＜0.05). 2. The weights of both right and left femur of osteoporosis-induced rats, administered with female or male antler-extract, little decreased compared with those of normal control group. 3. The bone ash quanties of femur of osteoporosis-induced rats, administered with female or male antler-extract, little decreased compared with those of normal control group. 4. The weights of liver, spleen, and kidney of osteoporosis-induced rats, administered with female or male antler-extract, decreased compared with those of normal control group. 5. Histological and electronic microscopical findings were (1) that in normal control rats the connectional of lacunae appeared well and were without loss of bone mineral, (2) that in ovariectomized rats the connections of lacunae were mostly broken and were with loss of bone mineral compared with those of normal control rats, (3) that in osteoporosis-induced rats, administrated with female or male antler-extract, the shape of lacunae and the connections of them were similar to those of normal control rats. These findings suggest a possible protective and therapeutic effects of female or male antler extract against bone loss in ovariectomized rats.

황해쑥(Artemisia argyi H.Lev. & Vaniot)은 우수한 항염증 활성을 지닌 것으로 다양하게 보고 되었다. 그러나, 대표적인 염증 질환 중 하나인 골관절염에 미치는 영향은 현재까지 알려져 있지 않다. 따라서, 본 연구에서는 염증 유발 연골 세포 및 골관절염 유발 동물 모델에 미치는 황해쑥 효과에 대해 조사하였다. 첫째, interleukin 1 beta를 투여한 관절 연골 세포에 황해쑥 물 추출물을 투여한 후 metalloporeinase (MMP) -3 및 MMP-13의 발현을 mRNA 및 단백질 수준에서 분석 하였다. 또한, 내측 반월상 연골의 불안정화에 의해 유도 된 골관절염 마우스 모델을 사용하여 황해쑥 물 추출물의 골관절염 억제 효과를 분석 하였다. 세포 실험에서, 본 황해쑥은 MMP-3와 MMP-13의 mRNA 및 단백질 발현을 유의하게 억제하였다. 또한. 황해쑥 물 추출물을 투여한 실험 동물의 관절 조직을 Safranin O 염색을 실시하여 분석한 결과 연골 하 골판 두께의 감소 및 활막 염증 개선 효과가 관찰 되었다. HPLC를 이용한 성분 분석 결과, 황해쑥 물 추출물은 항염증 및 항관절염 활성을 가진 jaceosidin과 eupatilin을 함유하는 것으로 나타났다. 본 연구결과로부터 황해쑥은 골관절염의 치료 또는 예방에 유망한 소재로 개발될 수 있음을 시사한다.

A 5-year-old castrated male Chihuahua weighing 1.54 kg was examined because of a several month history of progressive right hind limb lameness. Physical examination of the stifle joints revealed pain and a grade IV medial patellar luxation on the right stifle joint. The right and left stifle joints were associated with a lameness of grade 2 and grade 0, respectively. Radiography revealed osteophytes or subchondral cystic lesions on the right and left stifle joints. Osteoarthrosis (OA) scores for the right and left stifle joints were 20 and 12 respectively. Combination of surgery and implantation of autologous adipose tissue derived mesenchymal stem cells (aAT-MSCs) was determined with informed consent. $1{\times}10^6$ aAT-MSCs suspended in PBS and 0.6 mL of hyaluronic acid were injected in the right stifle joint postoperatively. Osteoarthrosis scores and the lameness grade for the right and left stifle joints were 19 and 13, and 0 and 0 19 months after treatment, respectively, and 14 and 15, and 0 and 0 five years after treatment, respectively. This case report shows radiographical evidence of a decrease in osteophytes and subchondral cystic lesions on the stifle joint with OA after aAT-MSCs injection.
