Polymorphic reticulosis(PMR) is a unique clinicopathological entity of unknown etiology, which commonly present as an aggressive, necrotizing lesion of the upper respiratory tract. It is a separate nosologic entity from Wegener's granulomatosis and idiopathic mildine destructive disease. The origin of the cells composing polymorphic reticulosis has been controversial. We reviewed 15 cases of polymorphic reticulosis with respect to clinical and histologic bases, and immunohistochemical studies were done using UCHLI (CD45RO), as a T cell marker, CD-20 as a B cell marker and alpha- I -antichymotrypsin as a histiocytic marker. Almost all cases showed characteristic histologic and immunohistochemical features similar to those of peripheral T cell lymphoma. Thus, this study indidcated that polymorphic reticulosis is a type of malignant lymphoma of T cell lineage.

OBJECTIVES: To determine if unilateral pedicle screw fixation is comparable to bilateral fixation in one-or two-segment lumbar spinal fusion. METHODS: Eighty-eight patients with spinal stenosis or spondylolisthesis were assigned to either unilateral or bilateral pedicle screw instrumentation groups. Demographic variables, preoperative diagnosis, number of fusion segments, and kinds of instrumentation used were similar between the two treatment groups. RESULTS: There were no significant differences between the two groups in terms of blood loss, clinical results, time at which fusion was complete, fusion rate, and complication rate. There were significant differences between the two groups in terms of duration of operating time, duration of hospital stay, medical expenses. The number of fusion segments or kinds of instrumentation did not affect the fusion rate, time at which fusion was complete, or clinical outcomes. Metal failure rate of unilateral fixation was higher in patients with spondylolytic spondylolisthesis than in patients with spinal stenosis. CONCLUSIONS: Unilateral pedicle screw fixation was as effective as bilateral pedicle screw fixation in lumbar spinal fusion independent of the number of fusion segments (one or two segments) or pedicle screw systems. Unilateral pedicle screw fixation is not recommended for spondylolytic spondylolisthesis patients who were treated with Gill' s decompression.

A survey of the literature on the treatment of ruptures of deltoid ligament associated with fracture of distal part of fibula is controversial. Some authors advocated surgical repair of the ruptured deltoid ligament based on the theoretical consideration, while others advocated non-operative treatment based on the clinical consideration. We studied the results in forty-five patients who were treated for disruption of the deltoid ligament and a distal fibular fracture. The length of follow-up in our series was twelve to twenty-four months, with an average of fifteen months. When the fibular fracture was adequately reduced and medial clear space was returned to its normal width, the 91 percents both of patients of being treated with repair of deltoid ligament and patients of being treated without repair had a good or excellent results.

Ultrasonography (US) is the primary diagnostic tool used to assess the risk of malignancy and to inform decision-making regarding the use of fine-needle aspiration (FNA) and postFNA management in patients with thyroid nodules. However, since US image interpretation is operator-dependent and interobserver variability is moderate to substantial, unnecessary FNA and/or diagnostic surgery are common in practice. Artificial intelligence (AI)-based computeraided diagnosis (CAD) systems have been introduced to help with the accurate and consistent interpretation of US features, ultimately leading to a decrease in unnecessary FNA. This review provides a developmental overview of the AI-based CAD systems currently used for thyroid nodules and describes the future developmental directions of these systems for the personalized and optimized management of thyroid nodules.

PURPOSE: To evaluate the impact of a retrotrigonal layer backup stitch (RTBS) during robot-assisted laparoscopic radical prostatectomy (RALP) on post-prostatectomy incontinence. MATERIALS AND METHODS: We compared the difference in continence recovery between 94 patients (group 1, as historical controls) and 57 patients (group 2). The only technical difference between our two groups was the incorporation of the retrotrigonal layer into the posterior aspect of the vesicourethral anastomosis (group 1: without RTBS; group 2: with RTBS). Postoperative continence recovery was defined as the use of no absorbent pads. RESULTS: In group 1, the continence rate at 3, 6, and 12 months postoperatively was 40.4%, 70.2%, and 90.4%, respectively;in group 2, the continence rate was 42.1%, 70.1%, and 89.7%, respectively. The median (95% confidence interval) time to continence recovery was four months (range, 1 to 12 months) in group 1 and four months (range, 1 to 9 months) in group 2. Kaplan-Meier curves showed no significant difference in the recovery of continence between the two groups (log rank test, p=0.629). CONCLUSIONS: A RTBS does not appear to improve urinary incontinence after RALP. Further anatomical study and prospective randomized studies will be needed to confirm this.

Meckel-Gruber syndrome is a quite rare congenital disorder, characterized by posterior encepalocele, cleft palate and lip, polycystic kidneys, hepatic fibrosis with bile duct proliferation, and postaxial polydactyly and syndactyly. We experienced an autopsy case of M eckel-Gruber syndrome in a second baby of 28 year-old woman. At 26 weeks of gestation, congenital anomaly was detected on ultrasonographic examination and the pregnancy was terminated. Familial history was not noted.

This study was designed to identify doxorubicin as a permanent chemomyectomy agent that overcomes reversible effect of botulinum toxin A. Doxorubicin was assessed for its ability to bring about a permanent chemomyectomy and the effects of pretreatment were observed to assess its ability to prevent any complications brought about by doxorubicin. A total of thirteen rabbits were assigned to the control group(n=3) and two experimental groups(n=5 for each group). To investigate the myopathic changes following the injections of the agent, both orbicularis oculi muscles of the lower eyelids of each rabbit in the control group were directly injected with single dose of 0.2ml normal saline. Group I were injected with 0.5mg/0.2ml of doxorubicin into the right eyelid and 1.0 mg/0.2 ml of doxorubicin into the left. Group II were given an intravenous injection of 35mg/kg of allopurinol as the pretreatment, then 30minutes later injected with 0.5mg/0.2ml of doxorubicin into the right and 1.0mg/ 0.2ml of doxorubicin into the left. The rabbits were examined daily to monitor the onset, duration and size of skin necrosis and histologically examined two and four months after initial injections. The myopathic change after doxorubicin injection was persistent and irreversible. The dose related effects of doxorubicin chemomyectomy were confirmed by the histologic finding. Skin necrosis occurred in all cases of doxorubicin injection(both 0.5mg and 1.0mg), however the allopurinol pretreatment decreased the size of the skin necrosis in case of the high dose(1.0mg) of doxorubicin. The combined use of allopurinol and doxorubicin reduced the myopathic change more effectively than doxorubicin use alone. Further study is needed to determine optimal dose and administration method, which we feel will contribute to safer and permanent chemomyectomy.

Ultrasonography (US)-guided procedures such as ethanol ablation, radiofrequency ablation, laser ablation, selective nerve block, and core needle biopsy have been widely applied in the diagnosis and management of thyroid and neck lesions. For a safe and effective US-guided procedure, knowledge of neck anatomy, particularly that of the nerves, vessels, and other critical structures, is essential. However, most previous reports evaluated neck anatomy based on cadavers, computed tomography, or magnetic resonance imaging rather than US. Therefore, the aim of this article was to elucidate US-based thyroidal and perithyroidal anatomy, as well as its clinical significance in the use of prevention techniques for complications during the US-guided procedures. Knowledge of these areas may be helpful for maximizing the efficacy and minimizing the complications of US-guided procedures for the thyroid and other neck lesions.
