Background. Lymphoma of the vocal fold is extremely rare due to low lymphoid content in the larynx. To date, fewer than 100 cases of laryngeal lymphoma have been reported; however, none of these literatures are concerned about exclusive laryngeal involvement of recurred lymphoma which initially appeared in other body sites. Specific consensus about management for these patients yet to exist, due to its rare occurrence; however, the main modality of treatment is chemotherapy alone or in combination with radiation therapy. Case. Herein, we report a case of a 51-year-old female patient who had recurrent T-cell lymphoma developing in bilateral vocal folds. The patient was originally diagnosed of T-cell lymphoma in right colic flexure 10 years ago, and was cured by chemotherapy. Immunohistochemical stain revealed the histologic type of recurred tumor in the vocal folds that are identical to the previously cured lymphoma. Conclusion. To the best of our knowledge, this was the first case that recurrent lymphoma occurred solely in the vocal folds. Despite its rarity, lymphoma should be put in the index of suspicion among those patients with decreased vocal fold mucosal wave without definite vocal fold mass who had a history of cured lymphoma.

The renewed interest in the use of hyperthermia in cancer therapy is bases on radiobiological and clinical evidence indicated that there may be a significant therapeutic advantage with the use of heat alone or combined with radiation or chemotherapy, There are many methods for generating heat for localized tumor as like radiofrequency, microwave, electromagnetic induction and ultrasound. But it is very difficult to be even thermal dose distribution and stable output of power and then the detection of temperature in tumor is difficult to be precise with thermocouples and semiconductor sensors. We designed the microwave heating generator, dipole antenna applicators and autometic temperature controlled thermocouples for localized hyperthermia on skin and in cavities. 1. The microwave generator with 120 W, 2,450MHz magnetron could be heating up to $40^{\circ}C\~50^{\circ}C\;for\;1\~2$ hours in living tissues. 2. The thermal dose distribution in tissue with microwave was described $42^{\circ}C\~44^{\circ}C$ with in 3 cm depth and $2\~6cm$ diameter area. 3. Skin surface heating applicator with spiral 3 times wave length antenna radiated high Power of microwave. 4, Intracavitary heating applicator with dipole antenna with autometic control temperature sensor kept up continuously constant temperature in tissue. 5. For constant thermal distribution, applied two steps power with 10W microwave after $17\~20W$ during first 10 minutes. 6.

This study examined the mediating effect of intimate partner violence (IPV) between alcohol use and relational satisfaction by the Actor Partner Interdependence Model (APIM). For this study, data were drawn from the 13^th-wave Korea Welfare Panel data and a total of 2,263 married couples were included in the analysis. SPSS 25.0 and AMOS 24 were used to analyze data and the Actor Partner Interdependence Mediation Model (APIMeM) examined the mediating effect. The results of this study are summarized as follows. First, the actor effect and the partner effect on the relationship of alcohol use and partner violence were all verified to be positive effects. Second, the actor effect and the partner effect on the relationship of partner violence and relational satisfaction were all verified to be negative effects. Third, comparison of the actor effect and partner effect between the husband and wife showed that the partner effect in which alcohol use to partner violence was greater in the husband than in the wife. In addition, both the actor and partner effect of violent reducing their relational satisfaction were greater in wives than in husbands. The findings of this study suggest that IPV has a mediating role between couples' alcohol use and the relational satisfaction and husband's violent behavior has more negative effect on the quality of the relationship than the wife's violent behavior.

Purpose: Crohn's disease (CD) is a chronic, idiopathic bowel disorder that can progress to partial or complete bowel obstruction. At present, there are no reliable diagnostic tests that can readily distinguish between acute inflammatory, purely fibrotic and mixed inflammatory and fibrotic. Our aim is to study the utility of contrast enhanced ultrasound (CEUS) in combination with shear wave elastography (SWE) to differentiate fibrotic from inflammatory strictures in children with obstructive CD of the terminal ileum. Methods: Twenty-five (19 male) children between 2016-2021 with CD of the terminal ileum were recruited into the study. Among these patients, 22 had CEUS kinetic measurements of tissue perfusion, including wash-in slope (dB/sec), peak intensity (dB), time to peak intensity (sec), area under the curve (AUC) (dB sec), and SWE. In total, 11 patients required surgery due to bowel obstruction. Histopathologic analysis was performed by a pathologist who was blinded to the CEUS and SWE test results. Results: Patients that underwent surgical resection had significantly higher mean area under the curve on CEUS compared to patients responsive to medical therapy (p=0.03). The AUC also correlated with the degree of hypertrophy and the percent fibrosis of the muscularis propria, as determined by histopathologic grading (p<0.01). There was no difference in the mean elastography measurements between these two patient groups. Conclusion: CEUS is a useful radiological technique that can help identify pediatric patients with medically refractory obstructive fibrotic strictures of the terminal ileum that should be considered for early surgical resection.
