Objective: To evaluate the safety and feasibility of prostatic artery embolization (PAE) via transradial access (TRA) compared with transfemoral access (TFA). Materials and Methods: This retrospective study included 53 consecutive men with lower urinary tract symptoms (LUTS) who underwent PAE between September 2018 and September 2021. Thirty-one patients (mean age ± standard deviation:70.6 ± 8.4 years) were treated with TFA, including 14 patients treated before adopting TRA. Since December 2019, TRA has also been attempted with the procedure’s selection criteria of patent carpal circulation and a height ≤ 172 cm, with 22 patients treated via TRA (69.1 ± 9.6 years). Parameters of technical success (defined as successful bilateral embolization), clinical success (defined as LUTS improvement), procedural time, radiation dose, and adverse events were compared between the two groups using the Fisher’s exact test, independent sample t test, Wilcoxon signed-rank test, or Mann-Whitney test. Results: All patients received at least one-side PAE. Technical success of PAE was achieved in most patients (TRA, 21/22; TFA, 30/31; p > 0.999). No technical problem-related conversion from TRA to TFA occurred. The clinical success rate was 85% (11/13) in patients with TRA, and 89% (16/18) in patients with TFA for follow-up > 2 weeks post-PAE (median, 3 months) (p > 0.999). The median procedure time was similar in both groups (TRA, 81 minutes vs. TFA, 94 minutes; p = 0.570). No significant dose differences were found between the TRA and TFA groups in the dose-area product (median Gycm2 , 95 [range, 44–255] for TRA and 84 [34–255] for TFA; p = 0.678) or cumulative air kerma (median mGy, 609 [236–1584] for TRA and 634 [217–1594] for TFA; p = 0.551). No major adverse events occurred in either of the groups. Conclusion PAE via TRA is a safe and feasible method comparable to conventional TFA. It can be safely implemented by selecting patients with patent carpal circulation and adequate height.

PURPOSE: To investigate the correlation of the strain elasticity of breast cancer with histologic features, immunohistochemical markers and molecular subtypes that are known to be factors related to prognosis. MATERIALS AND METHODS: B-mode ultrasound and strain elastography were performed in 123 patients (mean age, 53.4; range, 28–82) with invasive ductal carcinoma (IDC) (mean size, 1.54 cm; range, 0.4–7.0 cm). Histologic grade, lymph node (LN) status, lymphovascular invasion, immunohistochemical biomarkers [estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2 (HER2), CK5/6, epidermal growth factor receptor, and Ki-67] and molecular subtypes were determined from surgical pathology reports. The relationships between these factors and elasticity scores were evaluated. RESULTS: LN involvement was associated with a higher elasticity score which was statistically significant (p = 0.042). The tumor size, lymphovascular invasion, histologic grades, immunohistochemical markers and molecular subtypes had no significant correlation with the elasticity score (p > 0.05 for all). However, the IDCs with larger size and a positive lymphovascular invasion tended to have higher elasticity scores. Furthermore, higher histologic grade cancers and the HER2 overexpression-type tended to have lower elasticity scores. CONCLUSION The elasticity score of IDC had a significant correlation with LN involvement but no statistically significant correlation with the histologic features, immunohistochemical markers or molecular subtypes.

PURPOSE: The purpose of this study is to evaluate the usefulness of a two-stage approach to primary knee arthroplasty with recurrent septic arthritis. MATERIALS AND METHODS: We studied 22 patients with recurrent septic arthritis, and we observed them for more than one year of follow-up survey from January 2005 to April 2012 at Yeungnam University Medical Center. The clinical assessment was performed following Knee Society knee score, Knee Society function score, and International Knee Documentation Committee Score (IKDC) subjective assessment. In addition, we analyzed the causative organisms, significant medical comorbidities (diabetes mellitus), period up to primary knee arthroplasty, and radiologic assessment with reference to disease prognosis. RESULTS: The average range of postoperative knee motion showed a good result, with an average of 115degrees. Knee Society knee score improved from 23.5 to 81.0, and Knee Society function score also increased from 22.5 to 73.2. Subjective assessment by IKDC was divided into 15 normal patients and 7 nearly normal patients. No significant difference was observed between patients with causative organisms and those with diabetes mellitus. In the final follow-up survey, recurrence of infection was not reported. CONCLUSION: A two-stage approach to primary knee arthroplasty with recurrent septic arthritis is a useful method, because it showed good clinical and radiologic results and favorable subjective assessment.

Typhoid fever often manifests hepatic involvement but pleural involvement has rarely been reported to occur as a complication of typhoid fever. One case of typhoid pleurisy, in which Salmonella was isolated from the blood, is presented with the brief review of the literature. A 44 year old female was admitted to the hospital because of high fever, abdominal pain. Typhoid fever was diagnosed by blood culture, Widal test, and liver function test. Chest X-ray and pleural effusion examination demonstrated pleurisy. With the administration of ceftriaxone and pleural aspiration, she became afebrile with subsidence of pleural effusion.

The double pylorus is a fistulous communication between gastric antrum and duodenal bulb. It appears to be an acquired lesion in the majority of cases. Upon routine endoscopic procedures, it is frequently seem to occur in males who are either alcoholics, diabetics, those with chronic renal failure, chronic lung disease. If it is no developing complications such as septal rupture, double pylorus is well response to medical treatment. A 51-year-old man who had been taking medication over a long period for the chronic bronchitis was admitted to this hospital because of epigastric soreness and indigestion for 1 month. Endosopic findings showed two large openings of the pyloric channel and gastric ulcer in the channel. We thought that this case was an acquired lesion reasult of repeated gastric ulcer. We report a case of double pylrous with the brief review of literatures.

Tuberculous meningitis, which commonly causes thick granulations over the base of the brain, is a frequent cause of post-meningitic hydrocephalus. Raised intracranial tension affects the cause of tuberculous meningitis adversely. The development of hydrocephalus may account for the raised intracranial pressure. Insertion of a V-A(V-P) shunt significally alters the course of the disease. The results in 5 cases have been detailed and discussed. Operation could be performed even in an active stage of the disease without much fear of milliary dissemination.

A direct intracranial operative approach that occludes the neck of the aneurysmal sac by clipping, and excludes it from the circulation without interference with the lumen of the parent vessel, is the ideal treatment of symptomatic intracranial aneurysm. With this procedure, however, there is no assurance of complete obliteration of the aneurysmal sac. Furthermore aneurysms arising from the anterior communicating artery are particularly dangerous because of the effects produced by spasm of the important neighboring perforating vessels. Since Logue published on the treatment of anterior communicating aneurysms by proximal ligation of an anterior cerebral artery in 1956, there has been by the large number of series of cases reported by other surgeons. Tindall classified three pattern of angiographic filling in patients with anterior communicating aneurysms and in type III, each anterior cerebral artery fills from its respective side, while the aneurysm fills from one side only, proximal ligation of anterior cerebral artery was performed with good effect. Five patients with anterior communicating artery aneurysm were treated by proximal occlusion of the dominant anterior cerebral artery with no mortality or morbidity. There was also instance of recurrent hemorrhage during the follow up period for 8 months to 5 years. We thought this operative procedure, therefore, can offer a highly acceptable result if the surgeon applies strict criteria to patient selection. Technically, the procedure was simple, earlier and could be performed more quickly than the direct attack.

A case is presented in which left-sided hemiparesis was caused by a fibromuscular dysplasia of the right internal carotid artery in the neck, and it used as a basis for discussion of the angiographic features. The 24-year-old woman was admitted to our Department of Neurosurgery, Korea University hospital, with the complaints of headache and left-sided hemiparesis which developed abruptly about one month before this admission. The carotid angiography was performed by puncture of the right common carotid artery under the clinical impression of cerebral thrombosis, which showed no gross intracranial abnormalities. But the characteristic findings were observed under and widening of the arterial lumen which are so-called loose stocking appearance or 'string of beads' appearance and are the typical feature of fibromuscular dysplasia. No surgical interventions such as arterial reconstruction and grafting, or arterial dilatation with bougies were applied on the patient, and she was discharged from the hospital three days after the admission. Fibromuscular dysplasia is a rare sclerotic, noninflammatory lesion of unknown etiology involving the wall of large arteries. This disease is found most frequently in early adult life and women are afflicted more often than men, This condition has been described most often in the renal arteries, where it has been found to be a cause of hypertension. Among the involvement of carotid system, the cervical portion of the internal carotid artery is most often affected, and the involvements are often bilateral. When localized to the internal carotid arteries, it can give symptoms of intermittent or permanent cerebral ischemia, but is usually asymptomatic. The typical angiographic appearance is the main parameter for diagnosis of fibromuscular dysplasia.

Since Maisonneuve mentioned osteomyelitis by typhoid fever for the first time in 1835, numerous investigators had reported salmonella osteomyelitis. But these are very rare in its incidence ; only 0.82% of patients with typhoid infections have skeletal involvement. The authors recently experienced a case of salmonella osteomyelitis in lumbar spine respectively caused by salmonella typhi D group. A 48 year-old female was admitted to our Dept. of Neurosurgery with 4 months history of severe lumbago. On hospitalization her emperature raised upto 39 degrees C once and widal test showed salmonella typhosa OH 640x. Lumbar spine X-ray films demonstrated irregular bony destruction of L2 and L3 with mild degree of narrowing of intervertebral space of L2-3. Pus evacuation and currettage of involved vertebrae surgically were performed. Salmonella osteomyelitis involving intervertebral space was confirmed by culture of pus obtained from pathologic lesion and by biochemical test. Satisfactory result is obtained by surgical and antibiotic therapy.
