Augumentation rhinoplasty using autogenous cranial bone graft (outer table) can be used more successfully than other methods. In patients with congenital or posttraumatic severe saddle nose deformity and lateral deviation, cranial bone graft is an excellent method of augumentation. The advantages of cranial bone graft compared with traditional method of bone graft are summarized as follows; 1. Easy to reach donor site 2. Abundance of material 3. Little pain and functional disability 4. Shorter hospitalization period 5. Inconspicuous donor scar 6. No secondary deformity of donor site 7.Appropriate curvature can be obtained by proper selection of donor site. With the above advantages, we conclude that augumentation rhinoplasty using split cranial bone graft is a good method in correction of congenital or posttraumatic deformity of nose.

An axial-pattern flap can be transferred as the free-flap and has many merits over a random-pattern local flap. However, this has limitations of available vascular architecture and donor site. To overcome these problems, many types of prefabricated flaps have been designed using vascular bundles. It is possible to convert a random-pattern flap to a neovascularized axial-pattern flap by transferring a vascular pedicle. In an attempt to study the effects of prefabrication using vascular bundles, the survival rate between random-pattern flap and prefabricated axial-pattern flap was compared in this study. The rabbits were divided into two groups. The control group was consisted of the random-pattern flap and the prefabricated group was consisted of the prefabricated axial-pattern flap using femoral vascular pericles of rabbits. Femoral vascular pedicles were transferred under the 5x5cm lower abdominal flaps without any perivascular tissue. Three weeks later, random-pattern flaps were elevated without any axial vascular pedicle and prefabricated flaps were elevated based on the transferred femoral vascular pericles. The survival rate of the flaps in the control group and experimental group was 67.37% and 98.87% respectively. Based on the result of t-test there was significant difference between two groups. According to these results, it is concluded that prefabricated flap using transferred vascular pedicle was more effective than random-pattern flap. We think that this technique is versatile for wound repair and for use in other aspects of plastic and reconstructive surgery.

BACKGROUND: Direct observation of healthcare workers is commonly used in hospitals to investigate hand hygiene compliance. However, the hand hygiene compliance rate may increase due to the Hawthorne effect, which is the modification of behavior simply because subjects become aware that they are being observed. The objective of this study was to investigate the occurrence of the Hawthorne effect when directly observing hand hygiene compliance in intensive care unit (ICU) healthcare personnel. METHODS: A total of 87 staff members from the coronary care unit and cardiac surgery ICU of a general hospital in Seoul were included in this study: 24 residents and interns, 55 nurses, and 8 nursing assistants. Both covert and overt observations, where subjects were either unaware or aware of any direct observation, were performed on separate occasions. RESULTS: A total of 1,052 covert and 1,336 overt observations were documented over 30 and 34 occasions, respectively. Overall hand hygiene compliance was significantly higher with overt observation than with covert observation (1,041/1,336, 77.9% vs. 659/1,052, 62.6%, P<0.001). The Hawthorne effect was present in all professions and behaviors, with the exception of nursing assistants, and prior to touching a patient. CONCLUSION: Direct observation of hand hygiene compliance was associated with the Hawthorne effect when observations were made overtly and this was likely to contribute to an overestimation of compliance rate.

In this study the authors observed the status of water contamination by crayfish, Cambaroides similis, either alive or dead infected with Paragonimus westermani. The crayfish used as materials were infected heavily with metacercariae of Paragonimus westermani. The live crayfish were kept in water for a long time, and then the sediments of the water were examined to find out whether or not the liberation of the metacercariae from the body of the crayfish had caused contamination of the water with metacercariae. Killed crayfish were also preserved in water for some time. Physical stimuli in terms of mederate degree of shaking were added to the preserved water once a day and half amount of the water was replaced with tapped water of same temperature everyday. Status of the decay of the crayfish, liberation of the metacercariae from the body of the crayfish or contamination of the preserved water by the metacercariae, and numbers of metacercariae harboured in the body of the crayfish were examined everyday. The fate of the metacercariae liberated from the crayfish into water was also observed. Status of the decay of the crayfish, liberation of the metacercariae from the body of the crayfish or contamination of the preserved water by the metacercariae, and numbers of metacercariae harboured in the body of the crayfish were examined everyday. The fate of the metacercariae liberated from the crayfish into water was also observed. The results of this study can be outlined as follows: No metacercaria was detected in the water which contained live crayfish infected with Paragonimus westermani. The preserved water with dead or killed crayfish was found to be contaminated by the metacercariae of Paragonimus westemani, which had been caused by the decay and dispersion of the flesh of the crayfish The liberated metacercariae survived for 10 days in the water at 21-27 C. The liberated metacercariae were found to be sinking into water of s.g. 1.000 with average velocity of 35.8 cm per minute.

OBJECTIVE: To evaluate whether the rate of early mouse embryonal development could be enhanced by cumulus cell coculture in vitro. METHODS: Ham's F-10 culture media supplemented with 0.4% bovine serum albumin were used. Two-cell F1 mouse embryos were cultured in media with or without cumulus cells of female ICR mouse embryo for 96 hours, and the rates of embryonal development were observed and compared. RESULTS: The percentage of hatched blastocyst in the coculture group was significantly higher than that in the control group by 87.3% vs 64.8% respectively (p< 0.05). CONCLUSION: This study provides confirmative information that cumulus cell coculture will be useful in enhancing early mouse embryonal development.

The role of the long head of biceps brachii tendon in the stahilization of the head of the humerus is a highly interesting issue in recent studies. But, it is not well understood. Congenital absence of biceps long head tendon ot the hilateral shoulder joint is very rare and on review of literatures, we could not find any case reported. We experienced one case which was confirmed by magnetic resonance imaging and arthroscopic examination of the shoulder, and report it with review of literatures.
