Lymphangioma usually occurs in children and usually involves neck and axillary region. Renal or perirenal cystic lymphangioma, hepatic lymphangiomatosis and splenic lymphangiomatosis are very rare disorders. Perirenal cystic lymphangioma combined with multiple hepatic cysts or multiple splenic cysts suspected to be lymphangiomatosis has not been reported in adults in this country until now. The patient was a 43-year-old woman who had been diagnosed with multiple splenic cysts about ten years ago. She presented with a perirenal cystic lesion discovered incidentally and we detected small multiple hepatic cysts additionally with abdominal CT. We removed perirenal cyst surgically and a perirenal lymphangioma was confirmed.

BACKGROUND: Ketamine and dexmedetomidine are commonly used for sedation and analgesia in patients. We tried to compare the effects of intravenous ketamine and dexmedetomidine infusion on spinal block with bupivacaine. METHODS: Ninety American Society of Anesthesiologists physical status class I or II patients, who were scheduled to spinal anesthesia were randomly assigned to one of three groups (n = 30). Normal saline 10 ml, 5 ml/hr (loading dose for 10 minutes, infusion) (Group NS), dexmedetomidine 1 microg/kg, 0.5 microg/kg/hr (Group DEX), or ketamine 0.2 mg/kg, 0.5 mg/kg/hr (Group KET) was infused intravenously before spinal anesthesia. We recorded the time to highest sensory block level, sensory and motor regression, and hemodynamic changes. RESULTS: Patients in Groups KET had a significantly faster onset time of sensory block than patients in Group NS. The highest sensory block levels were not significantly different between groups. Average time of sensory regression and knee flexion, was significantly longer in the Group KET and Group DEX than the Group NS. CONCLUSIONS: Intravenous dexmedetomidine and ketamine were found to have a similar synergistic effect with intrathecal bupivacaine. Hemodynamic stability showed better results in Group KET.

The presence of severe pulmonary arterial hypertension (PAH) in patients with atrial septal defect (ASD) is still thought to preclude shunt closure, although there are several reports of good clinical outcomes after vasodilator therapy. We report the case of a young woman with ASD and severe PAH who was able to successfully undergo percutaneous shunt closure following 1 year use of the oral endothelin receptor antagonist, bosentan.

Erectile dysfunction (ED) is a highly prevalent disorder that affects millions of men worldwide. ED is now considered an early manifestation of atherosclerosis, and consequently, a precursor of systemic vascular disease. This study was designed to investigate the effects of male silkworm pupa powder (SWP) on the levels of nitric oxide synthase (NOS) expression, nitrite, and glutathione (GSH); lipid peroxidation; libido; and erectile response of the corpus cavernosum of the rat penis. We induced ED in the study animals by oral administration of 20% ethanol over 8 weeks. The SWP-treated male rats were divided into 3 groups that were orally administered 200, 400, and 800 mg/kg. The libido of the SWP-administered male rats was higher than that of the ethanol control group. In addition, the erectile response of the corpus cavernosum was restored in males on SWP administration, to a level similar to that of the normal group without ED. The testosterone concentration did not increase significantly. The lipid peroxidation in the corpus cavernosum of the male rats administered SWP decreased significantly. In contrast, compared to the ethanol group, SWP-administered male rats showed increased GSH levels in the corpus cavernosum. The level of nitrite and NOS expression in the corpus cavernosum of SWP-administered male rats increased significantly. These results indicated that SWP effectively restored ethanol-induced ED in male rats.
