PURPOSE: The authors studied the change according to altitude in the intraocular pressure (IOP) of rabbit models after intravitreal gas injection. METHODS: We injected C3F8 gas (pure gas, 0.4 cc) into the vitreous cavity in six pairs of rabbits. The six rabbits were divided into the Fast group and the Slow group. After 3 days, we measured the rabbits' IOPs at five different check points along the Young-Dong Expressway while traveling in a car. RESULTS: The IOPs of the Fast and the Slow groups at each check point, respectively, were 11.83+/-2.14, 13.00+/-3.69 (p=0.518) in Won-ju (130 m), 20.00+/-2.28, 21.17+/-2.14 (p=0.382) in Hoeng-seong (560 m), 28.00+/-2.60, 24.83+/-1.94 (p=0.038) in Pyeong-chang (580 m), 30.83+/-3.60, 26.67+/-1.63 (p=0.027) in Dae-gwall-yeong (805 m) and 9.83+/-1.17, 10.83+/-2.14 (p=0.338) in Kang-neung (70 m). We found that IOP increased with increased altitude in both groups. The IOP of the Fast group was significantly higher than that of the Slow group at the Pyeong-chang and Dae-gwall-yeong check points. CONCLUSIONS: We observed that IOP increased during car travel as altitude increased. In addition, we found that the rate of ascent was a risk factor for increased IOP. Therefore, it is important to inform patients with intraocular gas to avoid fast ascents during car travel and to ascend slowly after IOP has stabilized.

Nutcracker syndrome(renal vein entrapment syndrome) is probably more common than previously suspected. The nutcracker phenomenon refers to compression of left renal vein between aorta and superior mesenteric artery that results in elevation of pressure in left renal vein and develoment of collateral veins. This syndrome occurs in relatively young and previously healthy patients and is characterized by intermittent gross hematuria due to left renal vein hypertension, at times associated with flank pain, abdominal pain or varicocele. We report a 17 years-old male patient with this syndrome presented with flank pain, abdominal pain, and intermittent gross hematuria for 3 months. Urinalysis revealed protein(-), blood(+++), many RBC with only 1% of dysmorphic RBC. IVP and cystoscopy showed no remarkable finding but doppler ultrasonography and abdominal spiral CT revealed compression of left renal vein between aorta and superior mesenteric artery. Renal venography showed compression of left renal vein and collateral circulation to left gonadal vein and the pressure gradient between left renal vein and inferior vena cava was 11mmHg. The nutcracker syndrome should be considered as one of the causes of nonglomerular hematuria. All patients with unexplained severe left flank or abdominal pain, or unilateral hematuria from the left on cystoscopy, should be studied by selective renal venography and pressure measurement in inferior vena cava and renal veins. The patient with this typical syndrome could be treated surgically, by transposition of left renal vein and resection of collateral veins as the procedure of choice to correct the underlying pathologic process and eliminate these troublesome symptoms.

PURPOSE: The standard treatment of locally advanced nasopharyngeal cancer is a concurrent chemoradiotherapy (CCRT), and cisplatin has been used as the most popular chemotherapeutic agent. But many different doses and schedules for cisplatin administration such as daily, weekly and 3 week cycles have been proposed. We compared and analyzed the tumor response, the overall survival, the toxicity and the chemotherapy dose intensity in the patients with locally advanced nasopharyngeal cancer who were treated with CCRT. MATERIALS AND METHODS: We performed a retrospective study on 55 patients with locally advanced nasopharyngeal cancer, and they were treated with CCRT as a front-line treatment from Jan 1996 to Jun 2007 at Kangnam Saint Mary's Hospital. RESULTS: The patients had a median age of 53 years (range: 19~75 years). Of the total 55 patients, a 3-week cycle of 100mg cisplatin was administered in 31 patients and 30 mg weekly cisplatin was administered in 24 patients combined with radiotherapy. Twenty one patients had a complete response and four patients had a partial response for a response rate of 71.4% (95% CI: 59.5~83.3) after CCRT and followed by adjuvant chemo-therapy. The complete response rates for the 30 mg and 100 mg cisplatin groups were 72.7% (95% CI: 54.9~90.5) and 54.2% (95% CI: 36.7~71.7), respectively (p= 0.23). The duration of CCRT in the 100mg cisplatin group was significantly longer than that of the 30mg cisplatin group (11.1+/-2.9 weeks vs. 9.0+/-1.2 weeks, p= 0.003). The major deviation group, which was defined as prolongation of the radiotherapy duration for more than 2 weeks, had a significantly lower objective response rate than did the non-deviation group (56.3% vs 84.2%, respectively, p= 0.002). The major severe toxicities were leucopenia (49.1%), pharyngoesophagitis (49.1%), anorexia (43.6%), nausea (41.8%) and vomiting (40%). CONCLUSIONS: Weekly 30mg cisplatin-based CCRT is a practical, feasible cisplatin schedule for the patients with locally advanced nasopharyngeal cancer in regard to decreasing the interruption of radiation treatment and decreasing the treatment-related acute toxicities.
