Foreign body aspiration (especially peanut) is the leading cause of accidental death in children under 1 year of age and most cases of serious aspiration occur between the age of 1 and 3. We report a case of severe pulmonary complication and adult respiratory distress syndrome (ARDS) secondary to peanut aspiration in 15 month old male in spite of all removal (9 pieces) by ventilating bronchoscope. Chest X-ray showed pulmonary interstitial emphysema, marked subcutaneous emphysema, pneumothorax and autopsy findings showed interstitial inflammatory cell infiltration with destruction of acinar septal architecture and formation of hyaline membranes. Chest X-ray and pathologic findings are compatible with the late ARDS. A brief review of related literature was made.

STATEMENT OF PROBLEM: Use of custom tray and tray adhesive is clinically recommended for elastomeric impression material. However there is not clear mention of drying time of tray adhesive in achieving appropriate bonding strength of tray material and impression material. PURPOSE: This study is to investigate an appropriate drying time of tray adhesives by evaluating tensile bonding strength between two types of polyvinylsiloxane impression materials and resin tray, according to various drying time intervals of tray adhesives, and with different manufacturing company combination of impression material and tray adhesive. MATERIAL AND METHODS: Adhesives used in this study were Silfix (Dentsply Caulk, Milford, Del, USA) and VPS Tray Adhesive (3M ESPE, Seefeld, Germany) and impression materials were Aquasil Ultra (monophase regular set, Dentsply Caulk, Milford, Del, USA) and Imprint II Garant (regular body, 3M ESPE, Seefeld, Germany). They were used combinations from the same manufacture and exchanged combinations of the two. The drying time was designed to air dry, 5 minutes, 10 minutes, 15 minutes, 20 minutes, and 25 minutes. Total 240 of test specimens were prepared by auto-polymerizing tray material (Instant Tray Mix, Lang, Wheeling, Il, USA) with 10 specimens in each group. The specimens were placed in the Universal Testing machine (Instron, model 3366, Instron Corp, University avenue, Nowood, MA, USA) to perform the tensile test (cross head speed 5 mm/min). The statistically efficient drying time was evaluated through ANOVA and Scheffe test. All the tests were performed at 95% confidence level. RESULTS: The results revealed that at least 10 minutes is needed for Silfix-Aquasil, and 15 minutes for VPS Tray Adhesive-Imprint II, to attain an appropriate tensile bonding strength. VPS Tray Adhesive-Imprint II had a superior tensile bonding strength when compared to Silfix-Aquasil over 15 minutes. Silfix-Aquasil had a superior bonding strength to VPS Tray Adhesive-Aquasil, and VPS Tray Adhesive-Imprint II had a superior tensile bonding strength to Silfix-Imprint II at all drying periods. CONCLUSION: Significant increase in tensile bonding strength with Silfix-Aquasil and VPS Tray adhesive-Imprint II combination until 10 and 15 minutes respectively. Tray adhesive-impression material combination from the same company presented higher tensile bonding strength at all drying time intervals than when using tray adhesive-impression material of different manufactures.

Hamartoma of the breast is a rare benign lesion presenting as palpable mass. They are, however, sometimes misdiagnosed by pathologist due to their resemblance to other benign or physiologic conditions of the breast. We report two cases of hamartomas of the breast. The clinical diagnosis was fibroadenoma in both cases. One patient was a 49-year-old woman presented with palpable mass for the duration of 5 months. Mammography showed a well demarcated round mass with homogeneous density which is slightly greater than the surrounding glandular tissue. Grossly it was a 3.5 3.0 2.0 cm sized round firm mass covered by thin fibrous tissue. Microscopically it was a well defined mass composed of variable amount of breast lobules, dilated ducts and adipose tissue surrounded by dense hyalinized connective tissue. The adipose tissue accounted for 30% of the entire lesion. Cellular atypism was not found. The other patient was a 18-year-old woman presented with palpable mass of the duration of 3 years, which was increased in size recently. Mammography demonstratesd a well delimited lobulated mass with lucent halo. Ultrasonography showed a well encapsulated low echoic mass admixed with high echoic areas. Grossly, it was a 4.0 4.0 2.0 cm sized well demarcated oval-shaped firm mass with translucent thin fibrous capsule.. Microscopic findings were similar to the former. The amount of adipose tissue was 20%.

PURPOSE: Carnitine plays a key role in the oxidation of fatty acids by facilitating their transport. As very low birth weight(VLBW) infants receiving total parenteral nutrition(TPN) with limited oral intake are likely to be carnitine-deficient state, they require exogenous supplementation of carnitine, however, effects of it remains controversial. To demonstrate effects of parenteral camitine supplementation on fat metabolism, weight gain and clinical outcome. We analyzed plasma levels of biochemical markers, changes of weight, and incidence of complications in 23 VLBW infants receiving TPN. METHOD: We randomly assigned 23 VLBW infants(<32 wks of gestational age) receiving TPN to carnitine-supplemented(100mg/kg per day) group(n=10) and control(n=13). Plasma total (TC), free(FC), and acyl carnitine(AC) levels and serum cholesterol, triglyceride and free fatty acid levels were measured before and 2 weeks after carnitine supplementation. RESULT: Decrements in TC for 2 weeks were significantly lower in carnitine group(41.6umol/l->32.3umol/l) than control group(46.3umol/l->25.2umol/l)(p<0.05). Changes of FC and AC were similar in both groups. Levels of cholesterol and triglyreride were similar in both groups. Days of regaining birth weight were faster in carnitine group than control group(15.3+/-3.4 vs 20. 8+/-11.1 days)(p<0.05). Rate of weight gain for two weeks were significantly faster than carnitine group than control group(p<0.05). No significant differences in clinical outcome were found. CONCLUSIONS: Carnitine supplementation in VLBW infants receiving TPN has an supportive nutritional regimen in that it reduces decrement in carnitine level and facilitate weight gain.
