Purpose: The purpose of this study was to understand the meaning of gambling addiction from the perspective of problematic gamblers through their life stories. Methods: A narrative approach was utilized for this study. The data were collected from June 1 to September 30, 2019, from a purposive sample of three participants by using in-depth interviews, observations, and note-taking. Results: The participants told their life stories from childhood, stressing the experiences of being abused physically and emotionally by their own families. Their life stories commonly revealed that they became involved in gambling to escape the influence of the violence they had suffered. Due to their childhood abuse experiences, they had various problems, including distorted values toward money, low self-esteem, ambivalent feelings, and a lack of interpersonal coping skills, which often contributed to their addiction problems. Conclusion This study is meaningful in that it tried to understand the current addiction problem by focusing on the individual life experiences from the past to the present. Addiction recovery involves not only stopping the problematic behavior but also forming a new life meaning to lead a confident and independent future.

Purpose: The purpose of this study was to develop a theory on the gambling addiction process in adults who experienced domestic violence in childhood. Methods: Data were collected from 20 adults from May 1st to August 30th, 2020. Data were analyzed using grounded theory methodology as suggested by Strauss and Corbin. Results: The core category of this study was revealed to be ‘becoming addicted to gambling to avoid the physical and emotional pain caused by childhood domestic violence and be rewarded’. The core phenomenon was ‘struggle from pain’, which was derived from casual and contextual conditions: ‘ruthless physical violence’, ‘intolerable psychological pain’, and ‘bystand of violence’, ‘family addiction problem’. ‘parental immoral attitude’, The action and interaction strategies were ‘making money by any means’, and ‘gambling to forget the pain’. The intervening conditions affecting them were ‘a distorted view of money’, ‘resignation to helpless’, and ‘avoiding emotional distress’. The phases abbreviated through the produced process were the trauma phase, the avoidance phase, and the addiction phase. Conclusion Adults became addicted to gambling as a manifestation of distorted compensation mentality in an attempt to avoid the physical and emotional trauma of domestic violence in childhood.

Recent advancement in the radiotherapy technology has allowed conformal delivery of high doses of ionizing radiation precisely to the tumors while sparing large volume of the normal tissues, which have led to better clinical responses. Despite this technological advancement many advanced tumors often recur and they do so within the previously irradiated regions. How could tumors recur after receiving such high ablative doses of radiation? In this review, we outlined how radiation can elicit anti-tumor responses by introducing some of the cytokines that can be induced by ionizing radiation. We then discuss how tumor hypoxia, a major limiting factor responsible for failure of radiotherapy, may also negatively impact the anti-tumor responses. In addition, we highlight how there may be other populations of immune cells including regulatory T cells (Tregs), myeloid-derived suppressor cells (MDSCs), and tumor-associated macrophages (TAMs) that can be recruited to tumors interfering with the anti-tumor immunity. Finally, the impact of irradiation on tumor hypoxia and the immune responses according to different radiotherapy regimen is also delineated. It is indeed an exciting time to see that radiotherapy is being combined with immunotherapy in the clinic and we hope that this review can add an excitement to the field.

Diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) mapping are functional magnetic resonance imaging techniques for detecting water diffusion. DWI and the ADC map were performed for intracranial lesions in two dogs. In necrotizing leukoencephalitis, cavitated lesions contained a hypointense center with a hyperintense periphery on DWI, and hyperintense signals on the ADC maps. In metastatic sarcoma, masses including a necrotic region were hypointense with DWI, and hyperintense on the ADC map with hyperintense perilesional edema on DWI and ADC map. Since DWI and ADC data reflect the altered water diffusion, they can provide additional information at the molecular level.

A Yorkshire terrier (case 1) and a Miniature Schnauzer (case 2) were diagnosed with pylorogastric intussusceptions (PGIs). Both cases showed acute vomiting and had previous histories of laparotomy. In case 1, the invaginated pyloric wall was thickened unevenly containing multiple hypoechoic areas and had indistinct wall layering on ultrasonography. PGI with diffuse gastric edema and necrosis was confirmed on laparotomy. The dog recovered completely after gastrectomy and a Y-U plasty. Case 2 had uniformly thickened walls of invaginated gastric pylorus with the distinct wall layering. PGI was reduced spontaneously the next day.

Objective: To compare postoperative positional changes in the mandibular proximal segment between the conventional orthognathic surgery (CS) and the surgery-first approach (SF) using intraoral vertical ramus osteotomy (IVRO) in patients with Class III malocclusion. Methods: Thirty-eight patients with skeletal Class III malocclusion who underwent bimaxillary surgery were divided into two groups according to the use of preoperative orthodontic treatment: CS group (n = 18) and SF group (n = 20). Skeletal changes in both groups were measured using computed tomography before (T0), 2 days after (T1), and 1 year after (T2) the surgery. Three-dimensional (3D) angular changes in the mandibular proximal segment, condylar position, and maxillomandibular landmarks were assessed. Results The mean amounts of mandibular setback and maxillary posterior impaction were similar in both groups. At T2, the posterior portion of the mandible moved upward in both groups. In the SF group, the anterior portion of the mandible moved upward by a mean distance of 0.9 ± 1.0 mm, which was statistically significant (p < 0.001). There were significant between-group differences in occlusal changes (p < 0.001) as well as in overjet and overbite.However, there were no significant between-group differences in proximal segment variables. Conclusions: Despite postoperative occlusal changes, positional changes in the mandibular proximal segment and the position of the condyles were similar between CS and SF, which suggested that SF using IVRO achieved satisfactory postoperative stability. If active physiotherapy is conducted, the proximal segment can be adapted in the physiological position regardless of the occlusal changes.

Background: and Purpose Episodic ataxia type 2 (EA2) is characterized by recurrent vertigo and ataxia due to mutations in CACNA1A that encodes the α 1A-subunit of the P/Q-type voltage-gated calcium channel. This study aimed to determine intellectual function in EA2. Methods: During 2019–2023, 13 patients (6 males, age range=10–52 years, median age=29 years) with a genetically confirmed diagnosis of EA2 had their intellectual function evaluated using the Korean versions of the Wechsler Intelligence Scales (version IV) for adults or children in 3 referral-based university hospitals in South Korea. Results: The full-scale intelligence quotients (FSIQs) among the 13 patients were below the average (90–109) in 11, low average (80–89) in 5 (38.5%), borderline (70–79) in 1 (7.7%), and indicated intellectual disability (≤69) in 5 (38.5%). These patterns of cognitive impairments were observed in all four of the following subtests: verbal comprehension, perceptual reasoning, working memory, and processing speed. The FSIQ was not correlated with the ages at onset for vertigo and ataxia (Pearson correlation: p=0.40). Conclusions Patients with EA2 may have hidden intellectual disabilities even without a history of epilepsy or administration of antiepileptic drugs, and should be considered for genetic counseling and therapeutic interventions. Given the availability of medication to control episodic vertigo and ataxia, early diagnosis and management are important in preventing irreversible brain dysfunction in EA2.
