Keloids are pathologic fibroproliferative conditions characterized by excessive collagen deposition during wound healing. The pathogenesis of keloids is not fully understood, and current treatment options show variable results. In this case report, the patient developed a keloid after bilateral total thyroidectomy, and was treated with a combination approach using fractional ablative laser systems along with cryotherapy and triamcinolone injection. After seven monthly sessions of combination treatment, the patient presented marked improvement of the scar texture and symptoms. Furthermore, there was no recurrence for up to 2 years. We propose this combination as a safe and effective treatment option for keloid patients.

Potato virus Y (PVY) and potato leafroll virus (PLRV) are among the most damaging potato viruses and prevalent in most potato growing areas. In this study, cryopreservation was used to eradicate PVY and PLRV using two cryogenic methods. Potato shoot tips proliferated in vitro were cryopreserved through droplet-vitrification and encapsulation-vitrification using plant vitrification solution 2 (PVS2; 30% glycerol + 15% dimethyl sulfoxide + 15.0% ethylene glycol + 13.7% sucrose) and modified PVS2. Both cryogenic procedures produced similar rates of survival and regrowth, which were lower than those from shoot tip culture alone. The health status of plantlets regenerated from shoot tip culture alone and cryopreservation was checked by reverse transcription-polymerase chain reaction. The frequency of virus-free plants regenerated directly from highly proliferating shoot tips reached 42.3% and 48.6% for PVY and PLRV, respectively. In comparison, the frequency of PVY and PLRV eradication after cryopreservation was 91.3~99.7% following shoot-tip culture. The highest cryopreserved shoot tip regeneration rate was observed when shoot tips were 1.0~1.5 mm in length, but virus eradication rates were very similar (96.4~99.7%), regardless of shoot tip size. This efficient cryotherapy protocol developed to eliminate viruses can also be used to prepare potato material for safe long-term preservation and the production of virus-free plants.

This research objected to the diagnosed patients as acute lymphoblastic leukemia, acute myelogenous leukemia, neuroblastoma, non-Hodgkins lymphoma, Hodgkin's disease, kidney tumor, myelodysplastic syndrom and juvenile chronic leukemia after admission in the 'P' hospital in Pusan from Aug. 1. 1999 to Jan. 31. 2000. The results of this study are summarized as follows. 1. On the specific character between the experimental(exp.) group and the control (con.) group : there were 7 of 4-7 years old patients(the most) in the experimental group(53.8％), 5 of 12 years old or older patients in the control group (38.5％). Patients who experienced operation were 7 in the exp. group(53.8％) and 6 in con. group(46.2％). The largest number of the patients' diagnosis was acute lymphoblastic leukemia by 5 in the exp. group(38.5％) and 4 in the con. group (30.8％). The hardest nausea came on the second day by 5 in the exp. group(38.5％), 9 in the con. group(69.2％). 2. P-score of the nausea vomiting on the number of daily anticancer drug administration : first day, the exp. group got 9.6 and the con. group 17.6(P = 0.03). 2nd day, 10.9 and 19.4(P = 0.00), 3rd day, 10.6 and 18.3(P = 0.00), 4th day 10.0 and 18.0, 5th day 10.9 and 16.8(P = 0.05). The score showed statistically significant difference(P < .05). 3. Oral intake didn't show statistically significant difference between two groups. However the average of Oral intake of the exp. group was continually higher than the con. group except to the first day after administration. In conclusion, nursing intervention and nutrition care are much more needed on the 2-3th day after administration to reduce nausea vomiting, and for remission of nausea and enlarging oral intake it is utilizable to apply the easy, economic Oral Cryotherapy to the young patients who undergo chemotherapy.

Minor trauma to the uterine cervix is supposed to induce local immunity to prevent cervical lesions caused by human papillomavirus (HPV) infection. This study aimed to investigate the local cervical immunity in women with low grade squamous intraepithelial lesion (LSIL) and effects of abrasion after cryosurgery or Pap smear. One hundred women with LSIL and known results of HPV detection were recruited. HPV positive women were randomly divided according to abrasion into cryotherapy and Pap smear observation groups. Cervical tissues and cervico-vaginal lavage (CVL) were collected at 6 and 12 months after allocation. The levels of cytokines at first recruitment were compared with cytokine levels at 6 months after abrasions. The mRNA of IFN-${\gamma}$, TNF-${\alpha}$ and IL-10 in cervical tissues and these cytokines secreted in CVL were determined using real time PCR and ELISA, respectively. Anti-HPV16 IgG and IgA antibodies in CVL were assessed by western blotting. At first recruitment of women with LSIL (100 cases), IL-10 mRNA and cytokine in HPV positive group (60 cases) was significantly higher than negative group (40 cases). IFN-${\gamma}$ and TNF-${\alpha}$ mRNA level in both groups were comparable but their secretions in CVL were significantly increased in HPV negative group. After abrasion for 6 months in HPV-positive women, all mRNA and secreted cytokines were changed, but no significant difference was observed between cryotherapy and observation groups. When individuals were compared between first recruitment and after abrasion for 6 months, IFN-${\gamma}$ mRNA and anti-HPV16 L1 IgA antibodies were significantly increased in the cryotherapy group. The results suggest that modulation of local cervical immunities by abrasion might promote different effects in clearance of HPV-related cytological abnormalities.

Bronchial carcinoid tumors are relatively uncommon neoplasms that are considered to be malignant tumors of low to intermediate grade. They are classified by pathologic features as typical or atypical carcinoids and have distinctly different prognoses and therapeutic options. Surgery is the treatment of choice in typical and atypical carcinoid tumors but the approach has been changing. Recently, several studies have described experiences using other technologies as adjuncts to bronchoscopic resection, technologies such as laser and cryotherapy with curative intent in endoluminal typical carcinoids. Here we present a case of atypical bronchial carcinoid that was treated with bronchoscopic cryotherapy.

Although endobronchial hamartoma is a rare benign tumor, most patients with endobronchial hamartoma have respiratory symptoms such as obstructive pneumonia, hemoptysis, cough, or dyspnea due to bronchial obstruction. It can cause irreversible post-obstructive pulmonary destruction, thus early diagnosis and treatment is very important. Recently, there have been cases of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser and electrocautery procedures for bronchoscopic treatment of malignant or benign central airway obstruction with comparable therapeutic efficacy and few complications. Bronchoscopic cryotherapy is a newly developed technique for management of central airway obstruction. Moreover, it provides diagnostic methods with improving diagnostic yield and safety. We report two cases of endobronchial hamartoma, each diagnosed and definitively treated with bronchoscopic techniques. Endobronchial biopsy and removal was successfully performed by cryotherapy via flexible bronchoscopy without notable complications. Follow-up bronchoscopic examinations excluded residual or recurrent disease.

Although warts are a common skin condition/disease that recurs in childhood, treatment completion is difficult owing to the pain associated with conventional therapies. In this case, Korean herbal medicine, Guijakjihwang-Tang, and indirect moxibustion was used to treat a recalcitrant cutaneous wart without pain and recurrence. A 7-year-old boy presented with recurrent cutaneous warts on his right hand and received cryotherapy 3 times in the previous year. The wart recurred during the course of cryotherapy treatment, and the patient did not want to suffer any more pain from the previous treatment. Therefore, parents sought an efficient and painless therapy. The patient was treated for 2 months using Guijakjihwang-Tang combined with indirect moxibustion. The prominent lesion separated in the 2^nd month of treatment and completely recovered without adverse events in the 3^rd month. There was no recurrence over 12 months of follow-up. This report provides meaningful insights into the use of Korean medicine as a safe, painless and efficient treatment for warts in pediatric patients.

The purpose of this study was to identify the effectiveness of oral care protocol including individual oral care education, cryotherapy and benzydamine gargling on oral cavity status and self-care performance in solid cancer patients receiving chemotherapy. Thirty-one patients were enrolled by convenience sampling in this study and allocated to control (n=18) and experimental group (n=13). In the intervention group, individual oral care education, oral cryotherapy and benzydamine gargling were applied, while the control group received pre-existed oral care. Oral cavity status and self-oral care behavior were measured in five periods. The data were analyzed using the Mann-Whitney test, Friedman test, and Chi-square test. There was no significant difference in oral cavity status between the groups. But the two groups showed the poorest oral cavity status on $14^{th}$ day. Self-care behavior was significantly higher in the intervention group than the control group. This effect had maintained for 4months after completion of study. The results showed that individual oral care education by oncology nurse is effective to encourage patients to do self-care behavior and a further study is needed to explore the effect of cryotherapy and benzydamine gargling on oral cavity status of patient with solid tumor.
