PURPOSE: To study theeffect of micro incision (1.8 mm) and small incision (2.2 mm and 2.8 mm) coaxial phacoemulsification on surgically induced astigmatism (SIA) and high-order aberrations (HOA) of anterior and posterior corneal surface. METHODS: The present randomized clinical study included 32 eyes having a 1.8-mm, 38 eyes having a 2.2-mm, and 30 eyes having a 2.8-mm corneal incision. SIAs were measured at 1 and 3 months postoperatively. HOAs included coma, trefoil, and spherical aberration. The coma-root mean square (RMS) and trefoil-RMS were evaluated at 1 month after the cataract operation. RESULTS: Surgically induced astigmatisms were 0.41 +/- 0.30 diopter (D) in the 1.8-mm incision group, 0.47 +/- 0.21 D in 2.2-mm group and 0.71 +/- 0.50 D in the 2.8-mm group. The SIA of the 1.8-mm group was smaller than the other groups (p = 0.002). There was no statistically significant difference in coma, spherical aberration of the corneal anterior surface and trefoil, or spherical aberration of the posterior surface among the 3 groups at 1 month after surgery. CONCLUSIONS: Incision size contributes to postoperative corneal astigmatism. Phacoemulsification cataract surgery with less than 2.8-mm incision does not significantly influence the corneal aberrationsof anterior and posterior corneal surfaces.

BACKGROUND: Various kinds of pathogenic and non-pathogenic fungi have been isolated from the house dust, the closest environment of human beings. OBJECTIVE: Our purpose is to investigate the distribution of yeasts in house dust. METHODS: House dust was sampled from 22 families in Taegu and 56 in a rural town in Kyungpook province for 2 months from May to June, 1992. It was cultivated for years on the media containing cycloheximide (500mg/L) RESULTS: Among 78 families, 56 (71.8%) showed positive culture for yeasts in house dut;1 species in 24 (30.8%), 2 species in 19 (24.3%), 3 species in 12 (15.4%) and 4 species in 1(1.3%). Rhodotorula(Rh). Ruora was the most frequently isolated one from 36(46.2%) out of 78 families, followed by Tricosporn(T.) cutaneum 25(32.1%). Candida (C.) albicans 16 (20.5%), Pityrosporum pachydermatis 4 (5.1%) and Torulopsis candida, Cryptococcus laurentii, C. rugosa and C. guillermondii 1 (1.3%), each. CONCLUSION: Rh. rubra, T. cutaneum and C. albicans were the most important yeast species in the houst dust of both rural and raban areas.

BACKGROUND: Pruritus, which is a frequent accompanying symptom of dermatological diseases, is also common during pregnancy, either localized or generalized. It may be related to specific dermatoses of pregnancy. OBJECTIVE: A clinical study was performed to know the exact nature of pruritus in pregnancy. METHODS: Subjects with systemic diseases, or laboratory abnormalities were excluded. People who have had pruritic dermatologic diseases before pregnancy were also excluded. One hundred and fifty five pregnant women were interviewed with physical examinations and followed up to the date of delivery. Pruritus was graded. RESULTS: Pruritus was present in 31.6%. Most affected subjects had mild or moderate severity. The abdomen was the most common site. There was a tendency for the duration of itching to increase with the duration of pregnancy. CONCLUSION: Conclusion: These findings may provide basic and useful data on pruritus during pregnancy.

A case of lateral neck mass caused by thrombosis of the right external jugular vein is presented. Macroscopic examination of the excised thrombosed vein showed a pin-point opening of the jugular vein connecting to the hemorrhagic mass and microscopic examination revealed the vein to have an organized thrombus with somewhat degenerated vessel walls. Venipuncture would seem the most likely cause of thrombosis of the venous aneurysm in this 6 year old female patient.

BACKGROUND: Nausea, vomiting are among the most common postoperative complaints. We compared the effects of dexamethasone with or without propofol to the effects of conventional regimen consisting of enflurane-N2O in the prevention of postoperative nausea and vomiting. METHODS: Eighty healthy children, aged 3~14 yr, undergoing elective tonsillectomy were alldegrees Cated randomly to receive either 67% nitrous oxide and 1.5~2.0% enflurane or 67% nitrous oxide and propofol infusion 6~10 mg/kg/hr for maintenance of anesthesia. Dexamethasone 150 microgram/kg(maximum dose 8mg) or placebo was administered intrvenously(IV) in a double-blinded fashion before surgery. RESULTS: Dexamethasone reduced the overall incidence of vomiting from 45%(control) to 10%, Propofol also reduced from 45% to 15%. Combination of propofol anesthesia and dexamethasone administration reduced from 45% to 10%. CONCLUSIONS: Dexamethasone and propofol markedly decreased vomiting in healthy children after elective tonsillectomy.

PURPOSE: To report the clinical findings and the results of treatment on hematogenous pyogenic arthritis after major burn injury. MATERIALS AND METHODS: A retrospective analysis was made of 11, 797 major burn injury patients from January 1996 to June 2004. Severity of burn by involved body surface area, time of diagnosis, and laboratory findings were analyzed. Direct spread of infection from injured skin to superficial joint was excluded. RESULTS: Hematogenous infection was complicated in 26 joints of 22 patients (0.19% of overall cases). The mean age was 43.6 years, and mean follow-up was 46 months. The body surface area of burn injury was averaged 34.7%. The common involved area was hip in 10 patients, spine and shoulder in five patients, respectively. From the time of injury, average interval to development of symptom was 4.1 weeks, and to establish the diagnosis was 6.3 weeks. The most common isolated pathogen was Methicillin-resistant Staphylococcus aureus. A total of 22 joints underwent surgical treatment. The clinical results of the patients were poor in 72% due to recurrent infection and persistent pain. CONCLUSION: The results of this study suggest that major burn injury may be an important risk factor of hematogenous pyogenic arthritis. Careful clinical suspicion should be important for early diagnosis and treatment.

It is easy to view the laryngeal aperature with a flexible fiberscope through a laryngeal mask airway (LMA). This is a case report that the LMA could facilitate a fiberscope-aided tracheal intubation easily. Patient was a 59 year old female who had some limitation of mouth opening due to ankylosis of bilateral temporomandibular joints. After thiopental (200 mg) and succinylcholine chloride (50 mg) were given intravenously, a number 3 sized LMA was inserted and the lungs were ventilated via the LMA. The anesthesia cirele system is then disconnected from the LMA and a fiberscope, with the proximal end jacketed with a well-lubricated, cuffless, 6-mm-ID endotracheal tube (ETT); was inserted into the trachea through the lumen of the LMA. The 6-mm-ID ETT was threaded over the fiberscope into the trachea before fiberscope was withdrawn, and a traeheal tube exchanger was inserted through the ETT after enough ventilation for a while, followed withdrawal of the LMA and ETT. Finally, we can make the 7 mm-ID ETT with cuff insert into the trachea over a tracheal tube exchanger very easily without any difficulties.
