ABSTRACT
The olfactory groove schwannoma is a quite rare tumor. We report a case of a 49-year-old woman with an olfactory groove schwannoma attached to the cribriform plate without olfactory dysfunction. She had no specific neurological symptoms other than a headache, and resection of the tumor showed it to be a schwannoma. About 19 months after the operation, a follow-up MRI showed no evidence of tumor recurrence. Surgical resection through subfrontal approach could be one of the curative modality in managing an olfactory groove schwannoma. An olfactory groove schwannoma should be considered in the differential diagnosis of anterior skull base tumors.

PURPOSE: There is no data about the effect of anti-embolism stockings on intrasession hemodynamics in end stage renal disease patients on hemodialysis (HD). We investigated whether it affects the hemodynamic changes during HD or not. METHODS: We performed 2 HD sessions, before (stocking negative, SN) and after (stocking positive, SP) putting on thigh-high anti-embolism stockings in 11 ESRD patients on HD. In each session, cardiac output (CO), stroke volume (SV), central blood volume (CBV), and peripheral resistance (PR) were measured by ultrasound velocity dilution method at 1 and 3 hours of HD. Ultrafiltration (UF) amount was matched during study. Hemodynamic variables were compared between SN and SP. RESULTS: Mean ages were 51+/-14 years, female was 8, diabetes mellitus was 4, and duration of HD was 56.9+/-28.9 months. There were no differences in pre- and post-HD SBP and DBP, UF amount at 1 hr and 3 hr of HD, and total UF amount between SN and SP. At 1 hr of HD, CBV was greater in SP than in SN (0.85+/-0.32 L vs. 0.93+/-0.32 L, p=0.003). CO (5.56+/-1.22 L/min vs. 5.14+/-1.35 L/min, p=0.075) and SV (73.77+/-19.11 mL vs. 68.95+/-22.21 mL, p=0.05) tended to be increased in SP than in SN. However, there were no differences in TPR between 2 groups. At 3 hr of HD, there were no differences in all hemodynamic variables bewteen SP and SN. CONCLUSION: At early phase of HD, anti-embolism stockings seem to increase CBV, but this effect seems to be attenuated at later phase.

Rectus muscle hematoma is uncommon condition, caused by a tear in an epigastric vessel. Most cases were caused by direct trauma or anticoagulation therapy. In addition, it has been frequently associated with other conditions such as coughing, sneezing, vomiting, pregnancy, hypertension, prior paracentesis or laparotomy, excessive retraction in surgery. There are several reports of rectus muscle hematoma in renal failure, but no report has come out with CAPD patients in Korea. We herein present a case of rectus muscle hematoma due to severe cough in end-stage renal disease patient on CAPD.

With the development of the Tenckhoff catheter and subsequent Trochar device for percutaneous placement, a bed-side approach for peritoneal dialysis (PD) catheter insertion has been frequently used by nephrologists. Bleeding complications resulting from PD catheter placement are infrequent and massive bleeding by the rupture of inferior epigastric artery is very rare. We report a case of massive intra-abdominal hematoma caused by traumatic rupture of inferior epigastric artery during percutaneous placement of PD catheter.
