Acute osteomyelitis is usually shown as a localized area of increased activity (hot uptake) in the infectious focus on bone scintigraphy. In our patient, absence of radioactivity (cold lesion) was noted in the distal metaphyseal and diaphyseal regions of his right femur. Initial x-ray was interpreted as normal except for mild soft tissue swelling in the right thigh. The lesion was confirmed as an acute osteomyelitis with subperiosteal abscess on surgery. Staphylococcus aureus was the etiologic organism. We describe a case of acute osteomyelitis in a one-year-old boy shown as a cold lesion on bone scan.

After surgical operation in patients with arteriovenous malformation (AVM), normal pressure perfusion breakthrough (NPPB) is one of the major complications. Brain perfusion SPECT with acetazolamide stress was known to be useful to evaluate the vascular reserve in several neurological and neurosurgical conditions. The authors performed acetazolamide brain perfusion SPECT in patients with AVM and compared the brain perfusion in the post-operative clinical courses. The acetazolamide brain perfusion SPECT was helpful in defining the prognosis of the patients with AVM. We describe 4 patients with AVM who had acetazolamide brain perfusion SPECT to examine the prognosis.

OBJECTIVE: Heat shock protein family is related to protective mechanism of cells by environmental changes. This study was performed to evaluate the effect of cryopreservation on the heat shock protein 90 (Hsp90) expression in mouse ovarian tissue. METHODS: Cryopreservation of mouse ovarian tissue was carried out by slow freezing method. The mRNA level of Hsp90 expression in both fresh and cryopreserved mouse ovarian tissue was analyzed by RT-PCR. The protein expression of Hsp90 was evaluated by Western blot analysis and immunohistochemistry. RESULTS: The mRNA and protein of Hsp90 were expressed in both fresh and cryopreserved mouse ovarian tissue. The amount of Hsp90 mRNA was increased in cryopreserved ovarian tissue after 60 and 90 minutes after thawing and incubation. The amount of Hsp90 protein was increased in the cryopreserved ovarian tissue after 6 hours of the incubation in Western blot analysis. In immunohistochemical study, Hsp90 protein was localized in cytoplasm of oocytes and granulosa cells. Significant level of immunoreactive Hsp90 protein was detected in theca cells contrast to the weak expression in ovarian epithelial cells. CONCLUSION: This results showed the increase of Hsp90 expression in both mRNA and protein level in the cryopreserved mouse ovarian tissue. It can be suggested that Hsp90 may play a role in the protective or recovery mechanism against the cell damage during cryopreservaion.

It is been known that the deltoid ligament of the ankle joint plays an important role in the stabiliy of the ankle joint. In cases of deltoid ligament rupture, associated with lateral malleolar fractures, cannot be maintained the integrity of the mortise and the stability of the talus. Controversy remains about the treatment of deltoid ligament injuries. Many authors advocate an operative repair for deltoid ligament ruptures for optimal reduction of lateral malleolar fracture. However, according to recent cadaveric studies and many satisfactory results of clinical studies, excellent results have been reported regarding the ankle joint stability by anatomical reduction of the lateral structure, but only without surgical repair of the medial structure. Fourteen patients with lateral malleolar fractures with associated deltoid ligament injuries treated at Sun General Hospital between January 1990 and June 1995. There were examined clinically and radiologically. We concluded that deltoid ligament repairs should be considered unnecessary as long as fibular fracture are stabilized anatomically with normal medial joint space. However, in cases with higher fracture levels of lateral malleolus, associated with syndesmotic injury, we recommend syndesmotic screw fixation or deltoid ligament repair.

The contraceptive implant is an effective and well-established method of contraception. A 43-year-old woman presented with paresthesia and weakness of left hand. Symptoms began 3 weeks ago, immediately after removal of a contraceptive device in the left arm. A nerve conduction study showed proximal median neuropathy, and ultrasonography revealed focal swelling of the median nerve at the level of removal. Although nerve damage is a rare complication, special care should be taken to avoid nerve injury during removal procedure.

PURPOSE:This study was undertaken to investigate the prevalence and the risk factors of thrombocytopenia in children taking valproate for convulsive disorders. METHODS:From Jan. 2000 to Dec. 2005, we reviewed the medical recordes of 54 children with convulsive disorders taking valproate over a period of 12 months. Then, we estimated the prevalence of thrombocytopenia, and analyzed the relationship between changes in platelet counts and other factors such as age, sex, serum valproate levels and the duration of valproate therapy. RESULTS:Six(11.1%) children taking valproate had at least one episode of thrombocytopenia. The platelet counts were significantly lowered at 3 months after valproate therapy and recovered after 6 months(P<0.05). The relationship between the platelet counts and other factors such as blood valproate levels, sex and age was not observed in our study. CONCLUSION:Thrombocytopenia can appear after a few months of therapy and regular monitorings of platelet counts in children taking valproate may be needed to prevent potential bleeding diathesis.

The restoration of the fingernail is not simple in case of amputated distal fingertip which involved the pulp and nail. The nail should maintain a length of at least 2mm from the eponychium for an adequate grip and decent appearance. Various methods to reconstruct the fingernail bed are available. The nail bed graft from amputated finger or great toe, and free onychocutaneous flap are commonly used. The nail bed of the injured tip tends to be atrophied, deformed and failed as a graft. And the great toe is often turned down as a donor. We have restored satisfactorily the nail beds of three injured finger tips with eponychial cutaneous flaps. The pulps were reconstructed with either a reverse dorsal digital island flap or free pulp graft. Repeated again. A mean follow- up was six months. The nail grew up to the average of 3.7mm. All patients were satisfied with the length of the nail and met with good cosmetic results. An eponychial cutaneous flap is useful to restore the nail of the distal fingertip amputation. The procedure is relatively simple and morbidity is minimum.

The management of the third molar tooth in mandibular angle fracture is still controversial. Retrospective analysis of 197 cases of mandibular angle fractures associated with third molar tooth was undertaken. Selective prophylactic extraction of the third molar teeth were undertaken in 66 cases. The third molar teeth were retained in 131 fractures. The indication of extraction of the third molar teeth in mandibular angle fracture were as follows: 1) interfering with reduction of the fracture; 2) excessive mobility; 3) exposure of tooth root due to distraction of the fracture; 4) fractured teeth; 5) severely carious tooth 6) infected supporting structure. There were no significant differences between the complication rate in the "tooth removed" group and "tooth retained" group. Complications were minimal. Therefore proper management of the third molar tooth in mandibular angle fracture will minimize complication.

Authors report a case of cystic tuberculosis of left olecranon in a 44 year-old woman, which mimicked the bone tumor at initial presentation. She complained mild discomfort in the left elbow over a month. On examination there were no local redness, swelling, tenderness and deformity. There was no limitation of left elbow motion. After open curettage of the lesion, bone tuberculosis was confirmed by histological study. Postoperative triple chemotherapy of 12 months (Rifamcpicin, ethambutal, INH) could cure the disease.

PURPOSE: Varicella-zoster virus (VZV) infection is a common childhood disease. However, old and immune compromised patients are also at risk. Necrotizing fasciitis is a life threatening infection of the subcutaneous tissues, rapidly extending along the fascial planes. It is associated with a significant mortality rate, reported between 20% and 50%, and is therefore regarded as a surgical emergency. The authors treated a patient, who developed skin necrosis of her nose and left hemifacial area, following VZV infection. There are few literatures concerning this case; therefore, we present a rare case with review of literature. METHODS: A 39-year-old woman had shown a localized, painful, multiple bullae and eschar formation in her nose and left hemifacial area for several days. Her skin lesion had rapidly worsened in size and morphology. RESULTS: We diagnosed her as a necrotizing fasciitis, following herpes zoster, and then we performed a debridement of necrotic tissue and took a full thickness skin graft on her nose and left hemifacial area. Now, she was followed up with acceptable aesthetic result after 6 months. CONCLUSION: Secondary bacterial skin infection following VZV, can cause a result in a higher risk of complications. Among the complication, a necrotizing fasciitis of the head and neck is uncommon, and involvement of the nose is even more rare. Through this uncommon case report, we intend to emphasize the fact that early diagnosis of necrotizing fasciitis is very important, since it frequently necessitates surgical treatment which improves morbidity and leads to good recovery.
