Purpose: The goal of this study was to evaluate the efficacy of suction drains following total hip arthroplasties, by comparing the post-operative results between the group with suction drains and the group without suction drains. Materials and Methods: Eighty-six patients, who underwent primary total hip arthroplasties from June 2001 to June 2004, were divided into two groups: group 1 (48 patients), with suction drains; and group 2 (38 patients), without suction drains. We assessed the perioperative hemoglobin and platelet levels, the amount of total blood loss, the amount of post-operative blood transfusions, post-operative ranges of motion (ROMs, at 6 weeks), wound problems, and general conditions. Results: Although the postoperative hemoglobin level was greater in group 2 than in group 1, there was no statistically significant difference. The amount of total blood loss and blood transfusions in group 1 were statistically greater than in group 2 (p<0.05). There were no statistically significant differences in the post-operative ROMs and wound complications between groups 1 and 2. Conclusion: There were no limitations of hip motion and no wound complications in the patients without suction drains after total hip arthroplasties. However, they required fewer post-operative blood transfusions than did the patients with suction drains, due to less post-operative blood loss; and the absence of a suction drain might prevent retrograde tube infections. In addition, patients without suction drains after total hip arthroplasties seemed to recover better did than those with suction drains. Therefore, suction drains might provide no benefit in total hip arthroplasties.

Gynecomastia is a proliferation of the glandular component of the male breast. Gynecomastia is the most common variant condition of the male breast and results from the effect of an altered estrogen-androgen balance on breast tissue or from the increased sensitivity of breast tissue to a normal estrogen level. We experienced a case of macrogynecomastia in a 16-year-old boy who had a normal male phenotype and was treated by reduction mammoplasty with breast tissue removal, which was effective and produced good cosmetic and psychologic results.

OBJECTIVE: Percutaneous vertebroplasty (PVP) is usually carried out under three-dimensional (2D) fluoroscopic guidance. However, operative complications or bone cement distribution might be difficult to assess on the basis of only 2D radiographic projection images. We evaluated the feasibility of performing an intraoperative and postoperative examination in patients undergoing PVP by using three-dimensional (3D) reconstructive C-arm. METHODS: Standard PVP procedures were performed on 14 consecutive patients by using a Siremobil Iso-C3D and a multidetector computed tomography machine. Post-processing of acquired volumetric datasets included multiplanar reconstruction (MPR) and surface shaded display (SSD). We analyzed intraoperative and immediate postoperative evaluation of the needle trajectory and bone cement distribution. RESULTS: The male : female ratio was 2 : 12; mean age of patients, 70 (range, 77-54) years; and mean T score, -3.4. The mean operation time was 52.14 min, but the time required to perform and post-process the rotational acquisitions was 7.76 min. The detection of bone cement distribution and leakage after PVP by using MPR and SSD was possible in all patients. However, detection of the safe trajectory for needle insertion was not possible. CONCLUSION: 3D rotational image acquisition can enable intra- or post-procedural assessment of vertebroplasty procedures for the detection of bone cement distribution and leakage. However, it is difficult to assess the safe trajectory for needle insertion.

We present the case of a 38-year-old male who complained of repeated dizziness and syncope. Rotational vertebral artery syndrome (RVAS) was diagnosed via videonystagmoraphy (VNG), computed tomography angiography (CTA) and three-position digital subtraction angiography (DSA). In the neutral position, CTA and DSA revealed left vertebral artery (VA) stenosis at the C2 transverse foramen and right VA hypoplasia. When the head was turned to the right, the blood flow stopped at the C2 level. The bony structure around the VA at the C2 transverse foramen was decompressed via an anterior surgical approach, and the symptoms resolved. This case present the precise stenotic point evaluation by three-position DSA is crucial for the planning of surgical treatment.

Isolated ACTH deficiency is a rare cause of secondary adrenocortical insufficiency. The clinical presentation can be similar to that of primary adrenal insufficiency, but most of them may be nonspecific. A female patient of 25 months of age, complainig short stature, showed hypocortisolemia without ACTH & cortisol stimulation by insulin-induced hypoglycemia test. All the other hormone state was normal. Left hand AP view revealed delayed bone age(3 month) compared with chronological age. No radiologic abnormality was found in sella MRI and adrenal CT. Here we report a case of isolated ACTH deficiency presented by short stature.

Type 1 diabetes is a common metabolic disorder accompanied by increased blood glucose levels along with glucocorticoid and cognitive deficits. The disease is also thought to be associated with environmental changes in brain and constantly induces oxidative stress in patients. Therefore, glucocorticoid-mediated negative feedback mechanisms involving the glucocorticoid receptor (GR) binding site are very important to understand the development of this disease. Many researchers have used streptozotocin (STZ)-treated diabetic animals to study changes in GR expression in the brain. However, few scientists have evaluated the hyperglycemic period following STZ exposure. In the present study, we found GR expression in the hippocampus varied based on the period after STZ administration for up to 4 weeks. We performed immunohistochemistry and Western blotting to validate the sequential alterations of GR expression in the hippocampus of STZ-treated type 1 diabetic rats. GR protein expression increased significantly until week 3 but decreased at week 4 following STZ administration. GR expression after 70 mg/kg STZ administration was highest at 3 weeks post-treatment and decreased thereafter. Although STZ-induced increase in GR expression in diabetic animals has been described, our data indicate that researchers should consider the sequential GR expression changes during the hyperglycemic period following STZ exposure.

OBJECTIVE: The intracranial pathologies after head trauma should be usually progressed. It is clearly visualized in the non-invasive brain CT. The invasive monitor such as intracranial pressure (ICP) monitoring may be accompanied with the complications. This study aims whether the patients with severe head injury could be managed with serial CT scans. METHODS: The medical records of 113 patients with severe head injury in the prospectively enrolled trauma bank were retrospectively analyzed. After the emergency care, all the patients were admitted to the intensive care unit for the aggressive medical managements. Repeat brain CT scans were routinely taken at 6 hours and 48 hours after the trauma. ICP monitoring was restrictively applied for the uncertain intracranial pressure based on the CT. The surgical intervention and the mortality rate were analyzed. RESULTS: Immediate surgical intervention after the initial CT scan was done in 47 patients. Among the initially non-surgical patients, 59 patients were managed with the serial CT scans and 7 with the ICP monitoring. Surgical interventions underwent eventually for 10 patients in the initially non-surgical patients; 1 in the ICP monitoring and 9 in the serial CT. The mortality rate was 23.7% in the serial brain CT and 28.6% in the ICP monitoring. There was no statistical difference between two groups in the aspect of mortality (p=0.33). CONCLUSION: Serial CT scans in time could be a good way to monitor the intracranial progression in the severe head injury and reduce the implantation of an invasive ICP probe.
