With the continuous development of diagnostic techniques of precancerous lesion and an improved patient-transfer system, it is unusual to examine patients who have a life-threating malignant skin lesion. However it is still a problem in some far-advanced inoperable skin tumors which have been neglected and have become aggravated, Another problem in oncologic surgery is previous irradiation around a lesion. The only effective way to treat these lesions is to excise widely and cover with an appropriate free flap. But in such conditions, selection of recipient vessel is not easy. Many surgeons have used vein graft as the conduit from a distant non-radiated vessel to the free flap. This technique requires a long segment of vein for anastomosing both the artery and vein. We used intra-lesional vessels as the recipient vessel of the free flap, which were suspiciously damaged by irradiation and malignant cell infiltration. The guidelines include: 1) malignancy-infiltrated vessels are to be dissected until a clear field is obtained under a frozen section 2) irradiated vessel can be used only if active spurting is present without intraluminal thrombosis. All of our case obtained satisfactory results in all cases except one of irradiated squamous cell carcinoma at inguinal area whose gracilis myocutaneous free flap loss was in 10%. But even this case, the cause of partial loss of the flap may not be due to a vascular problem but an internal failure of the flap. We concluded, that carefully selected intra-lesional vessels, although they may be damaged by irradiation or malignant cell infiltration can be used as the recipient vessels of free flaps.

PURPOSE: To evaluate dysphagia objectively and quantitatively, and ta clarify the effect of neck position and viscosity changes in patients with aspiration and laryngeal penetration. MATERIALS AND METHODS: We studied 35 patients with dysphagia and 21 normal controls using videofluoroscopy and scintigraphy. Videofluoroscopy was performed with barium with three different viscosity, and scintigraphy was done, with water, yogurt, and steamed egg mixed with Tc-99m tin colloid. 1f aspiration was found during videofluoroscopic examination, patients neck position was changed and study repeated. Videofluoroscopy was analyzed qualitatively. We calculated 7 quantitative parameters from scintigraphy. According to the videofluoroscopic findings, we divided patients into 3 subgroups; aspiration, laryngeal penetration, and no-aspiration group. RESULTS: The result of videofluoroscopy revealed that the most cornmon finding was the delay in triggering pharyngeal swallow. Pharyrigeal transit time (PTT) and pharyngeal swallowing efficiency(PSE) in patients with aspiration were significantly different from other groups. After neck position change, aspiration could be reduced in all of 7 patients, and laryngeal penetration reduced hy about 82%. PTT ancl PSE were also improved after position change. Aspiration and laryngeal penetration occurred more frequently in thin liquid swallowing than in thick liquid and solid swallowing. CONCLUSION: PTT and PSE were useful for the evaluation of dysphagia. Aspiration and laryngeal penetration could be reduced when appropriate position assumed, We could decrease the chance of aspiration by changing the patient diet consisIency. Scintigraphy might be useful tool to quantitate and follow up these changes.

The finger-tip is a specially-differentiated end structure of the human body in anatomic aspect. Although it is covered with thick dermis and a heavily-cornified epithelial layer, the finger-tip represents tremendous sensory perception because of dense sensory nerve endings. This highly sensitive skin is attached to the phalangeal bone or fascia and stabilizd during grip or pinch by the fascial septa, which form compartments of fat pads in the pulp tissue. In addition to its functional aspect, the finger tip plays an important cosmetic role because it is an exposed area like the face. So, when reconstructing finger-tips, especially the thumb or radial side of the index finger, one must take into account both the functional and esthetic results. In this study, 8 cases of great toe pulp sensory free flaps for fresh amputations (n=4) and previously reconstructed wounds (n=4) are included. In previously-reconstructedcases cases, all of them complained of incomplete recovery of sensation or cosmetic dissatifaction. The fingers covered with flaps were the index finger (n=5), ring finger (n=2), and thumb (n=1). The mean size of flaps was 3 x 1.9 cm and all of the flaps survived without significant complications, except 1 case of venous insufficiency. Sensory complications, except 1 case of venous insufficiency. Sensory perception was detected within 4 months and improved gradually during the follow-up period to 10.5 mm/8 mm in static/moving two-point discrimination test. Even though, some patients complained of postoperative paresthesia including cold intolerance (37.5%), pain (25%) and hyperesthesia (12.5%), the great toe pulp sensory flap is an aesthetically superior and sensuously more satisfactory alternative to other reconstructive procedures for fingertip defects.

The study presents the application of STR polymorphisms to male identification in the cases of a serial rapist in Korea. Since October 2000 a rapist from Cheongju city (a town located in central district) committed at least 36 rapes. DNA profiles obtained from semen stains, buccal cells and tongue tissue left at the scenes of crime and vaginal swabs of victims gave information that one and the same man had committed all the rapes. The Y-chromosome haplotype (12 loci) obtained was used for the identification process of rapist in mixed genotypes including victim's alleles. The crime scene data were referred from investigating police authorities described the relationship of victim to the offender, victim's age, time and place of sexual assault and rape locations. The behavioural analysis of crime scenes showed more similarities than differences for related crimes. These components were usually assessed in terms of proximity in time and space. Certain crime scene aspects of a serial rapist help identify components of offender spatial behaviour. As a result of this work, future research on the geography of rape and behavioural aspects of rapist will be directed towards those aspects of offences, which have been identified as relevant to the distance between an offender's base, and the site where he approached his victim.
