A urinary calculus in the urethra is rarely seen and usually encountered in men with a urethral stricture or diverticulum. Herein, we report a rare case of a giant calculus in the urethra of a 42-year-old male patient with paraplegia after spinal cord injury due to car accident 20 years ago. A recent urologic consultation from the emergency room was performed since the patient had multidisciplinary symptoms during the day without any urination and presented with urinary difficulties due to hematuria and pain symptoms occurring with a mass in the bottom of the testicles. Abdomen and pelvic computed tomography (CT) was performed to examine the tumor mass, which was found to be absent. In addition, urethral stones were observed in the CT. Cystostomy was performed after the first urethroplasty, and the stone was removed from the urethra. Two weeks later, the patient was subjected to urethrography to remove the Foley catheter. No specific finding in voiding was detected. Giant urethral stones sometime require differentiation from tumor status. Treatment may vary according to size and location, requiring careful examination.

The mammalian ovary is innervated by sympathetic and sensory neurons which contribute to regulating several aspects of ovarian function, including blood flow, steroidogenesis and follicular development. The existence of a neural connection between central neurons and the ovary has been rarely reported, but the mechanism underlying integration of ovarian activity to broader neuroendocrine responses has not been reported. We have now used a viral transneuronal tracing technique combined with a conventional retrograde labeling procedure of CT-HRP to demonstrate that oxytocin-producing neurons of the hypothalamus are synaptically connected to the ovary. Since ovarian activity is suppressed but the activity of oxytocin neurons is increased during breast feeding. Our finding that the oxytocinergic neural connection is likely to provide a direct transsynaptic mechanism by which the central nervous system maintains the state of infertility that accompanies lactation in mammals.

Leiomyosarcoma is extremely rare in the oral cavity and especially in the mandible. At first. the case of this report was diagnosed as odontogenic fibroma but after approximately 3.5 years. it was diagnosed as leiomyosarcoma. Conventional radiograph of the first time showed an ill-defined radiolucent lesion in the mandible. After local recurrence. CT images showed a large irregular soft tissue mass with some necrotic areas. These findings were not specific for leiomyosarcoma, but they suggested that this lesion was a recurrent soft tissue sarcoma. Histopathological examinations using H & E staining, immunohistochemical staining and Masson's trichrome staining confirmed this case as leiomyosarcoma. Deciding its malignancy or benignancy, defining the tumor extent and its relationship to the surrounding anatomic structures, and evaluating the distant metastasis are more important roles of radiographic examination than finding out the name of disease.

Pulmonary actinomycosis is a rare disease entity to undergo thoracic surgery. We experienced a 49-year-old man with pulmonary actinomycosis who was admitted due to recurrent hemoptysis. Prior to admission, he was diagnosed as pulmonary tuberculosis on the basis of his clinical manifestations and chest radiological findings. The plain chest x-ray and chest computed tomography(CT) showed a cavitary lesion in left upper lobe and was given anti-tuberculous medication, but the x-ray revealed no imprcovement. He underwent left upper lobe lobectomy with segmentectomy of lower lobe and the surgical specimen showed no evidence of mycobacterial infection, but revealed sulfur granules which is a typical pathological finding of actinomycosis. He was discharged uneventfully and is scheduled to receive 6 months of antibiotic treatment.

Recently, some authors reported that discogenic low back pain should be regarded as a referred pain in respect of neural pathway. The afferent pathways of discogenic low back pain is transmitted mainly by sympathetic afferent fibres from the sinuvertebral nerves in the second lumbar nerve root. This pain arises from the lumbar intervertebral discs, and it had been transmitted mainly through the sympathetic afferent fibres contained in the second lumbar spinal nerve root. Second lumbar dermatome corresponds to the low back area. We experienced a case of low back pain which could not be controlled by conventional therapy and progressed wax and wane. The CT finding showed bulging disc between $L_4$ and $L_5$ and spinal stenosis in $L_4$ area. And epiduroscopic feature showed severe adhesion in $L_4$, $L_5$ and $S_1$. After we blocked $L_2$ root, pain score decreased 10 to 2. Therefore, the $L_2$ root block may be a useful diagnostic procedure as well as provide therapeutic value.

Objective : The goal of this study is to evaluate the clinical results in six patients who underwent surgical decompression for the acute subdural hematomas[ASDH] of posterior cranial fossa. Methods : Six patients [five males and one female] who had undergone surgery for ASDH of posterior cranial fossa between 2000 and 2005, were evaluated retrospectively with regard to clinicoradiological findings and surgical outcomes. The mean age was 45.8 years [range $9{\sim}67\;years$]. Results : Preoperative computed tomography showed ASDH on cerebellar hemisphere in four patients and on midline in two. All patients had the associated lesions such as subarachnoid hemorrhage, epidural or subdural hematoma, intraventricular hemorrhage, contusion or pneumocephalus in supratentorial area. Fracture of occipital bone was noted in two patients. Of the four patients who had 13 to 15 of Glasgow coma scale score at the time of admission, three were deteriorated within 24 hours after trauma. Of these three patients, delayed subdural hematoma developed 1 hour after initial normal CT finding in one patient and increased in thickness in another one. Postoperative outcome showed good recovery in three patients and moderate disability in one. Two patients were expired. Conclusion : This study supports that early diagnosis based on strict observation and prompt surgery in the patients with ASDH in posterior fossa will lead to the best results.

Purpose: Absorbable implants are frequently used to fix facial bone fractures, because they are radiolucent and compatible with magnetic resonance imaging (MRI). Despite their increasing usage, however, there have been few reports about their long-term side-effects. In this paper, a case in which absorbable implants led to a foreign body reaction 17 months after their insertion is presented. Methods: A previously healthy 19-year-old male fell from a flight of stairs and visited the authors' hospital with right periorbital pain. Zygomaticomaxillary fracture involving right orbital floor was detected via a facial bone computed tomography (CT). Internal fixation with absorbable implants was followed by open reduction. 17 months after the surgery, the patient complained of localized periorbital swelling. Removal of the granulomatous lesion including the absorbable implants along with their biopsy and culture was performed. Results: The granulomatous lesion around the implants was firm and extended into the maxillary sinus. The histologic finding showed a microabscess with a foreign body reaction. Methicillin-sensitive Staphylococcus aureus growth was confirmed in the culture. No definite abnormal symptoms ensued after the complete removal. Conclusion: A microabscess-forming granulomatous lesion around the absorbable implant can cause delayed symptomatic foreign body reaction despite its rare occurrence. Complete removal of the lesion including implants is expected to have a successful outcome if it is encountered.

The purpose of this study is to analyze the medical care utilization behavior of patients to whom treatment (surgery) is recommended after they are diagnosed with abnormal findings on health screening and factors affecting the selection of the medical institute for treatment. The data was collected from 291 patients who need treatment or surgery, according to the abnormal findings on the additional examination such as cardiac CT, brain MRI, Gastroscopy and Colonoscopy since four diseases are suspected among of 2,752 people who receive health screening. The results are as follows. First, the most common disease of patients who have abnormal findings by the diagnosis through the results of first testing is colon disease based on through the additional examination. The most common disease of patients who will get treatment (surgery) based on final diagnosis by a doctor who determines the result of health screening on the basis of diagnosis from the first testing is cardiovascular disease. Second, in terms of diseases, patients with cardiovascular disease select the medical institute where they get the health screenings as a place for treatment. Patients with cerebrovascular disease select another medical institute for treatment. Finally, the affective factors of selectivity treatment facility on health screening satisfaction were human, facility, health screening and revisit factors.

A hidden primary tumor presenting as an isolated lung mass is a diagnostic challenge to physicians because the diagnosis of lung cancer is likely to be made if the histologic findings are not inconsistent with lung cancer. A large lung mass was found incidentally in a 59-year-old man. Although adenocarcinoma was diagnosed by percutaneous needle biopsy, thyroid transcription factor-1 (TTF-1) immunostaining was negative, raising suspicion that there was another primary site. There was no abnormal finding except for the lung mass on a $^{18}FDG$-PET/CT scan and the patient did not complain of any discomfort. Finally, prostatic cancer was confirmed through the study of tumor markers and prostate-specific antigen (PSA) immunostaining. Because of the rare presentation of a single lung mass in malignancies that have another primary site, physicians should carefully review all data before making a final diagnosis of lung cancer.
