Purple urine bag syndrome (PUBS) was first reported in 1978, and is a rare phenomenon in which purple staining of the bags occurs, with a violet discoloration of the plastic of the catheter bag due to fine blue crystals of indigo in the urine. PUBS occurs predominantly in chronically catheterized constipated women, and is associated with urinary tract infections due to bacteria that produce sulphatase/phosphatase. A 70-year old male patient, who as used a suprapubic cystocatheter for almost 12 months, due to acute urinary retention, visited to our department with a purple colored urine bag. PUBS has previously been reported to be observed mostly in female patients. Herein, we report a rare case of PUBS in male patient.

A primary sclerosing lipogranuloma of the scrotum is a rare disease, the cause and pathogenesis of which are still unknown. We experienced a 38-year-old man with a painless intrascrotal mass. The mass was firm, and rapidly increased in size in 3 weeks. The patient denied a history of injection of exogenous materials, or of trauma to the scrotum or penis. During the surgical operation, the mass was found to be partly fixed to the scrotal skin, but not to the corpus cavernosum, corpus spongiosum or bilateral spermatic cords. The mass extended deeply into the perineal region. The pathological findings were epithelioid granulomas, with multinucleated giant cells, lymphocytes and eosinophils. Herein, we report a case of a primary sclerosing lipogranuloma in the scrotum.

PURPOSE: One of the most serious complications of benign prostatic hyperplasia (BPH) is acute urinary retention (AUR). Up to now, many papers have evaluated the short term treatment of patients with AUR that is due to BPH. Therefore, we evaluated the long term follow-up of BPH patients with AUR. MATERIALS AND METHODS: 154 BPH patients with AUR were divided into two groups. One group was considered to be the failure cases of urethral catheter removal, and this group (55 patients) had undergone immediately transurethral resection of prostate (TURP). The other group was considered to be the successful cases of urethral catheter removal. The latter group was divided into 3 groups: the alpha-blocker group, the alpha-blocker with 5alpha- reductase inhibitor group and the suprapubic cystostomy with medical treatment group. We evaluated the long term follow-up of these groups and the changes of treatment for 1 month, 3 months, 6 months and 12 months. RESULTS: The mean volume of the prostate was 54.2ml. When the patients were admitted to the hospital due to AUR, 53% of the patients had previously experienced AUR, and the mean number of previous AUR episodes were 1.4 times. The initial management of AUR due to BPH was urethral catheter indwelling with medical treatment. If the catheter removal failed, TURP was perfomed (35%) and when successful, medical treatment was then done. CONCLUSIONS: The primary management of AUR due to BPH is urethral catheter indwelling with medical treatment (alpha-blocker). However, if the patients have a large size prostate, we should first consider hormone treatment (5alpha-reductase inhibitor) rather than surgical treatment. The management methods of some patients were changed during the follow-up. Therefore, when following up these cases, we should be careful to prevent the recurrence of AUR and to allow self-voiding.

An 88-year-old man presented with a left temporal pulsatile mass that developed after blunt trauma. Based on suspicion of hematoma, needle aspiration was performed with the removal of approximately 15 mL of blood. No evident improvement was noted, and active arterial bleeding was observed at the needle puncture site. Doppler ultrasonography revealed a “yin-yang” sign, and the mass was diagnosed as a pseudoaneurysm of the left superficial temporal artery. Under general anesthesia, the superficial temporal artery was ligated and the pseudoaneurysm was removed. Superficial temporal artery pseudoaneurysm is a rare facial tumor that generally occurs after blunt trauma. Due to its rarity, pseudoaneurysms are often misdiagnosed as hematoma. The treatment of choice is excision, although endovascular intervention is a potential treatment option. However, when a pseudoaneurysm is small, conservative treatment can be used.

Hidradenitis suppurativa (HS) is a chronic inflammatory condition that is difficult to diagnose, with a period of 10.0± 9.6 years from symptom onset to diagnosis. A 32-year-old Asian man presented with bilateral postauricular abscesses that first appeared 5 years previously. Despite several incisions and drainage, the symptoms only temporarily improved and continued to recur. On physical examination, chronic scars and sinus tracts were observed around the lesion. Postauricular HS was diagnosed, and surgical treatment was performed. We performed a wide excision and reconstructed the defect using a posterior auricular artery perforator-based keystone flap. Histological examination confirmed the diagnosis of HS. The reconstruction was successful, and there was no recurrence for 2 years after surgery. HS is difficult to diagnose without specific attention. Although the postauricular region is not a typical site of HS, it can occur in this area. Therefore, if a patient presents with recurrent abscesses in the postauricular region, HS should be considered. Additionally, if HS is diagnosed in the postauricular region, wide excision with reconstruction using a posterior auricular artery perforator-based keystone flap can lead to a favorable outcome.

Although DNA damage responses (DDRs) are reported to be involved in nitric oxide (NO) production in response to genotoxic stresses, the precise mechanism of DDR-mediated NO production has not been fully understood. Using a genotoxic agent aphidicolin, we investigated how DDRs regulate NO production in bovine aortic endothelial cells. Prolonged (over 24 h) treatment with aphidicolin increased NO production and endothelial NO synthase (eNOS) protein expression, which was accompanied by increased eNOS dimer/monomer ratio, tetrahydrobiopterin levels, and eNOS mRNA expression. A promoter assay using 5’-serially deleted eNOS promoters revealed that Tax-responsive element site, located at −962 to −873 of the eNOS promoter, was respon-sible for aphidicolin-stimulated eNOS gene expression. Aphidicolin increased CREB activity and ectopic expression of dominantnegative inhibitor of CREB, A-CREB, repressed the stimulatory effects of aphidicolin on eNOS gene expression and its promoter activity. Co-treatment with LY294002 decreased the aphidicolin-stimulated increase in p-CREB-Ser133 level, eNOS expression, and NO production. Furthermore, ectopic expression of dominant-negative Akt construct attenuated aphidicolin-stimulated NO production. Aphidicolin increased p-ATM-Ser1981 and the knockdown of ATM using siRNA attenuated all stimulatory effects of aphidicolin on p-Akt-Ser473 , p-CREB-Ser133 , eNOS expression, and NO production. Additionally, these stimulatory effects of aphidicolin were similarly observed in human umbilical vein endothelial cells. Lastly, aphidicolin increased acetylcholine-induced vessel relaxation in rat aortas, which was accompanied by increased p-ATM-Ser1981 , p-Akt-Ser473 , p-CREB-Ser 133 , and eNOS expression. In conclusion, our results demonstrate that in response to aphidicolin, activation of ATM/Akt/CREB/eNOS signaling cascade mediates increase of NO production and vessel relaxation in endothelial cells and rat aortas.

Symptoms of tuberous scelrosis (TS) are mainly related with brain and kidneys. Seizure, mental retardation, other behavioral problems are dominant. A spectrum of renal tumors from benign angiomyolipoma (AML) to polycystic kidney disease, and rarely malignant renal cell carcinoma have been observed. Cystic AML is a rare phenotype of AML. No case of TS with renal cystic AML has been reported in Korea yet. And chronic kidney disease (CKD) in TS has been seldom reported. We experienced a TS case accompanied by renal cystic AML and CKD diagnosed in a 48-year-old female patient who was hospitalized for left side weakness and seizure under the diagnosis of acute cerebral infarction.
