Clinical studies on thirteen patients with Behcet's syndrome who had visited during the period from Jan. 1970 to Sep. 1973, to the Department of Dermatology & Ophthahnology, Busan National University Hospital, were made and the following results obtained. 1) The ratio of male vs. female was l. 0: l. 6 with no definite sexual differences. The ages ranged from 17 to 56 years with the peak incidence in third decade of life. 2) The "complete" form consisting of oculo- oro-genital and cutaneous lesions appeared in . 4 patients (30. 8%) and the "incomplet" in 9 patients (69. 2%). 3) Aphthous stomatitis was most predominant, being observed in 12 out of all 13 cases (92.3%), the next was cutaneous manifestations such as erythema nodosum, pyodermas, acneiform & pustular lesions and erythema multiforme in 10 cases (76. 1%) and genital ulcers in 9 cascs (69.2%). Ocular lesions and articular involvements came fourth, each being found in 8 cases (61. 5%). 4) The commonest feature of ocular involvement was relapsing iridocyclitis, being observed in 57. 7% and the disease led to a bilateral loss of vision in 38. 4% 5) Single or combined therapy including corticosteroids and antimicrobials gave transient conservative effects and was of no value to prevent recurrent attacks.

Alveolar soft part asrcoma is a primary malignant neoplasm that very rarely occurs in the orbit and it's histogenesis is uncertain. Authors reported a case of alveolar soft part sarcoma occurred primarily in the orbit. The patient, 58 years old Korean male, was admitted to Busan National University Hospital on June 9, 1972 with the chief complaints of the protrusion of the orbital content and pain in the left eye which were gradually developed after receiving enucleation for treatment of the orbital tumor, lasted for 3 months, on Feb. 21, 1972 at local clinic. The patient family history was not contributory. His medical history revealed prior episodes of typhoid fever, liver disease, and a chronic ethanol intake. Physical examination revealed chronic ill appearence in general condition, absent breathing sound at the right lower quadrant of the chest and 3 finger palpable liver. On eye examination, the right eye had good vision and no structual abnormalities, whereas the left side showed anophthalmos, protrusion of the intraorbital content on which surface was rather soft and smooth. We found tortous and dilated superficial skin vessels on the zygomaticotemporal area at which a soft mass was palpated in small fist size. On X-ray studies, there were bony destructive lesion on superior and lateral orbital margin in the skull, atlectatic pattern on the right lower lobe and notching pattern on the right diaphragm in the chest, and other long bone series showed no specific abnormal findings. On liver scanning, mottled areas on the right lower lobe were noted. There were no abnormal findings in C.B.C., urinalysis, C.S.F., stool and blood chemistry. The further studies for the abnormal findings containing liver lesion and atlectatic lung pattern could not perform because of patient's incooperation. We tried the exenteration of left orbit under the general anesthesia on July 8, 1972 but biopsy only performed because the tumor seemed to be extended to pterygoid fossa through the destructed zygomatic bone and to adjacent orbital bone. Histopathological findings showed striking features of alveolar soft part sarcoma; The tumor cells were arrlinged in alveolated or organoid patterns with delicate fibrous band or endothelium lined spaces. The cells were characterized by large, round, oval, and polyhedral cells with rather abundant cytoplasm, which were acidophilic and occasionally contained fine granules and vacuoles in H-E stain. The nuclei were almost located in eccentric, and binucleated, hyperchromatic, anaplastic and occasional mitotic figures were evident.

The survival rate and motility recovered after cryopreservation of testicular spermatozoa in testicular sperm extraction (TESE)-ICSl program is low. The purpose of this study was to assess the availability and efficiency of mouse empty zona pellucida in cryopreserving human TESE spermatozoa. Mouse empty zonae pellucidae were obtained by extraction of cytoplasm with or without cytochalasin B treatment. Motile sperm from proven-fertile donor and two azoospermic patients after TESE were individually inserted into empty zona pellucida and cryopreserved. Two to five days after cyropreservation, the frozen sperm were thawed and the rates of recovery and motility were observed. The ooplasmic extraction rates of control (N=80) and cytochalasin B treated oocytes (N=80) were 94.0% and 96.2%, respectively (p>0.05). The post-thaw recovery rates of spermatozoa and rates of motility recovery of ejaculate (N=70) and testicular (N=70) sperm were 97.1%, 97.1% and 95.7%, 94.3%, respectively (p>0.05). The results of this study showed that the mouse zone pellucida is useful for cryostorage of single testicular spermatozoa.

Nemaline myopathy is a genetically heterogeneous neuromuscular disorder and one of the most common congenital myopathies. The clinical manifestations usually vary depending on the age of onset. Neonatal nemaline myopathy has the worst prognosis, primarily due to respiratory failure. Several genes associated with nemaline myopathy have been identified, including NEB, ACTA1, TPM3, TPM2, TNNT1, CFL2, KBTBD13, KLHL40, KLHL41, LMOD3, and KBTBD13. Here, we report a neonatal Korean female patient with nemaline myopathy carrying compound heterozygous mutations in the gene KLHL40 as revealed using next generation sequencing (NGS). The patient presented with postnatal cyanosis, respiratory failure, dysphagia, and hypotonia just after birth. To identify the genetic cause underlying the neonatal myopathy, NGS-based gene panel sequencing was performed. Compound heterozygous pathogenic variants were detected in KLHL40: c.[1405G>T];[1582G>A] (p. [Gly469cys];[Glu528Lys]). NGS allows quick and accurate diagnosis at a lower cost compared to traditional serial single gene sequencing, which is greatly advantageous in genetically heterogeneous disorders such as myopathies. Rapid diagnosis will facilitate efficient and timely genetic counseling, prediction of disease prognosis, and establishment of treatments.

The incidence of prostate cancer (PCa) is increasing concomitantly with population aging. Accordingly, interest in radiation therapy (RT) and the frequency of RT are also increasing. The types of RT can be broadly divided into external beam RT (EBRT), brachytherapy (BT), and combination therapy (EBRT+BT). Lower urinary tract symptoms (LUTS) after RT for the treatment of PCa are common; however, there are few reviews on the relationship between RT and LUTS. Herein, we review the causes and incidence of LUTS, as well as the evaluation and treatment options. Because of the reported risks of RT, patients undergoing RT should be counseled regarding the challenges of treatment and informed that they may have higher failure rates than nonirradiated patients. Moreover, thorough evaluation and treatment strategies are needed to support treatment recommendations. With a review of the existing literature, this narrative article provides an overview to aid urologists in treating patients presenting with complications associated with RT for the treatment of PCa. Further research is required to provide evidence of the effectiveness and feasibility of the management approach to the care of patients with LUTS after RT for the treatment of PCa.

Periventricular nodular heterotopia (PNH) is a neuronal migration disorder that occurs during early brain development. Patients with PNH may be asymptomatic and have normal intelligence; however, PNH is also known to cause various symptoms such as seizures, dyslexia, and cardiovascular anomalies. PNH is not commonly diagnosed during early infancy because of the lack of clinical manifestations during this period. We present the case of a female infant diagnosed with PNH based on brain magnetic resonance imaging, who had symptomatic patent ductus arteriosus that had to be ligated surgically and had prolonged feeding cyanosis with frequent apneic spells.

PURPOSE: The aim of this study was to evaluate the efficacy of a daily dose of tadalafil 5 mg as well as its safety for the cardiovascular system in men with erectile dysfunction. MATERIALS AND METHODS: This study included a total of 162 men who were administered a daily dose of tadalafil 5 mg between April and December of 2009. A total of 127 men completed the 8-week clinical trial. The International Index of Erectile Function (IIEF)-5, blood pressure, and heart rate were measured before treatment with tadalafil (V1) and 4 (V2) and 8 weeks (V3) after treatment with tadalafil. Adverse effects were assessed at V1, V2, and V3. In cases in which the International Prostate Symptom Score (IPSS) was > or =8 at V1, maximal flow rate (Qmax) and postvoid residual volume (PVR) were measured. RESULTS: The IIEF-5 values were 11.25+/-3.18, 14.56+/-3.79, and 16.91+/-3.56 at V1, V2, and V3, respectively, with significant improvement (V1 vs. V2, p<0.001; V1 vs. V3, p<0.001). The IPSS values were 10.59+/-5.56, 9.07+/-6.06, and 8.15+/-6.10 at V1, V2, and V3, respectively, and the differences were statistically significant (V1 vs. V2, p<0.001; V1 vs. V3, p<0.001). There were no significant differences in blood pressure or heart rate. Adverse effects were observed in 7 men (5.51%) at V2 and in 5 men (3.94%) at V3. CONCLUSIONS: Tadalafil 5 mg administered once-a-day may be effective in improving erectile function. Adverse effects on the cardiovascular system may be minimal. In addition, it is believed that this may also be effective in improving voiding symptoms.
