Holoprosencephaly*

We reviewed 14 children with unilateral fractures of femoral shaft who had an angular deformity after union of 10° to 25°. At an average follow-up of 32 months(15 to 65), we measured remodelling of the proximal physis, the distal physis and the femoral shaft. The average correction was 83% of the initial deformity and there was no relation between the remodelling rate and degrees of malunion. Of the correction of angulation, only 27% had occurred at the fracture site and 73% at physis. The ability of physis to remodel better than that of fracture site. In children under 13 years of age, malunion as much as 25° in flexion deformity will remodel enough to get normal alignment of the joint surfaces.

BACKGREOUND: Cerebral damage caused by hemorrhagic shock presents an important challenge for critical care medicine. The type of fluid to resuscitate hemorrhagic shock is important for the outcome of such patients. Pentastarch is low-molecular-weight hydroxyethyl starch, which increases cerebral blood flow (CBF) by plasma volume expansion and compensatory vasodilation, and improves the microcirculation in the ischemic brain area by reducing the blood viscosity. METHODS: The authors continuously determined CBF and CMRO2 in 10 mongrel dogs weighing 20.1 +/- 0.8 kg with posterior sagittal sinus outflow method. Dogs were subjected to the 20 minute-period of hemorrhagic shock to a mean arterial pressure of 40 mmHg. The shock phase was followed by resuscitation with the same volume of 10% pentastarch as blood loss. The authors assessed the changes of CBF, CMRO2, and CBF/CMRO2 ratio immediately and 30, 60, 90, 120 minutes after pentastarch infusion. Brain water content was assessed by the wet-dry weight method. RESULTS: CBF was increased above the control level, immediately and 30 minutes after 10% pentastarch infusion (p<0.05), and approximated to the control level for the remaining time. CMRO2 was increased, immediately and 30, 60, 90 minutes after 10% pentastarch infusion (p<0.05), and approximated to the control level at 120 minutes. CBF/CMRO2 ratio was recovered to the control level after 10% pentastarch infusion. Brain water content was not significantly different from the normal value of dogs. CONCLUSION: 10% pentastarch may be used with safety to resuscitate hemorrhagic shock because it recovers the balance between the cerebral oxygen supply and demand, and does not cause cerebral edema.

BACKGROUND: Direct laryngoscope may be less useful under conditions of limited visualization. Light wand is a lighted stylet to transilluminate neck tissues allowing intubation without visualization. Thus, difficult intubation due to anatomy can be overcome. For comparison of light wand and direct laryngoscope, we checked time to intubation (TTI), success rate, relation of TTI and thyromental distance (TMD), and change of blood pressure and heart rate after intubation. METHODS: We selected and randomly allocated sixty adults to direct layngoscope group (D) and light wand group (L). Without premedication, propofol and vecuronium were injected for intubation. Time to intubation was measured from the time of grasping direct laryngoscope or light wand until the time of inserting endotracheal tube into trachea. We checked the change of blood pressure and heart rate after intubation, and studied the correlation of TTI and TMD. RESULTS: TTI was 16.5 sec (6.53~115.3 sec) for group D and 11.8 sec (4.31~36.0 sec) for group L. There was no significant difference between the groups. The rise of blood pressure and heart rate was less with light wand. There was a correlation of [TTI]=1248- 388[TMD]-30[TMD]2 in group L patients whose TMD is less than 7 cm. CONCLUSION: Compared with direct laryngoscope, light wand is as easy to use and can be more effective especially for patients whose anatomy may make intubation difficult or whose cardiovascular system is unstable.

Anisakiasis is a parasitic infectious disease caused by eating raw, infected fish. It causes severe abdominal pain-like acute abdomen, but not fatal. Anisakiasis was firstly reported by van Thiel et al. in 1960 in Netherlands and it has subsequently been reported in the Netherlands, Japan, the United states, Korea as well as other nations. Because Koreans like eating raw fish, the anisakiasis of the stomach was occasionally reported, but the case of severe gastric bleeding was very rare. So we report one case of gastric ulcer bleeding due to gastric anisakis larva proven by endoscopy and gastric resection.

An intraosseous epidermal cyst is a rare benign cystic lesion. It is thought to result from congenital factors or trauma and can lead to bone destruction because the cyst develops at the soft tissue around the bone. Radiological findings of intraosseous epidermal cysts are a well-defined radiolucent lesion, with cortical expansion. It is important to differentiate an intraosseous epidermal cyst with other disease developed at distal phalanx because its clinical and radiological findings are similar. We report two rare cases of intraosseous epidermal cysts that developed at the distal phalanx.

PURPOSE: There is no established formula for estimating renal depths in Korean. As a result, we undertook this study to develop a new formula, and to apply this formula in the calculation of glomerular filtration rate (GFR). MATERIALS AND METHODS: We measured the renal depth (RD) on the abdominal CT obtained in 300 adults (M:F=167:133, mean age 50.9 years) without known renal diseases. The RDs measured by CT were compared with the estimated RDs based on the Tonnesen and Taylor equations. New formulas were derived from the measured RDs in 200 out of 300 patients based on several variables such as sex, age, weight, and height by multiple regression analysis. The RDs estimated from the new formulas were compared with the measured RDs in the remaining 100 patients as a control. In 48 patients who underwent Tc-99m DTPA renal scintigraphy, GFR was measured with three equations (new formula, Tonnesen and Taylor equations), respectively, and compared with each other. RESULTS: The mean values of the RDs measured from CT were 6.9 cm for right kidney of the men (MRK), 6.7 cm for left kidney of the men (MLK), 6.7 cm for right kidney of the women (WRK), and 6.6 cm for left kidney of the women (WLK). The RDs estimated from Tonnesen equation were shorter than the ones measured from CT significantly. The newly derived formulas were 12.813 (weight/height)+0.002 (age)+ 2.264 for MRK, 15.344 (weight/height)+0.011 (age)+0.557 for MLK, 12.936 (weight/height)+ 0.014 (age)+1.462 for WRK and 13.488 (weight/height)+0.019 (age)+0.762 for WLK. The correlation coefficients of the RD measured from CT and estimated from the new formula were 0.529 in MRK, 0.729 in MLK, 0.601 in WRK, and 0.724 in WLK, respectively. The GFRs from the new formula were significantly higher than those from the Tonnesen equation significantly, which was the most similar to normal GFR values. CONCLUSION: We generated new formulas for estimating RD in Korean from the data by CT. By adopting these formulas, we expect that GFR can be measured by the Gates method accurately in Korean.
