The effective dose due to the X-Ray radiography in the patient positioning for the heavy ion radiotherapy was measured on three regions, chest, upper-abdomen and pelvis. All the radiographic systems and the conditions used in the measurements were same as the clinical trial being performed in National Institute of Radiological Sciences, Japan. The organ or tissue for measurements was selected by following ICRP60$^1$ and the effective dose was calculated from measured organ doses and the surface dose.

Hypersensitivity Pneumonitis (HP) one of the most common interstitial lung diseases (ILDs) is characterized by exposure to an inhaled inciting antigen that leads to a host immunologic reaction determining interstitial inflammation and architectural distortion. The underlying pathogenetic mechanisms are unclear. The absence of international shared diagnostic guidelines and the lack of a "gold-standard" test for HP combined with the presence of several clinical and radiologic overlapping features makes it particularly challenging to differentiate HP from other ILDs, also in expert contests. Radiology is playing a more crucial role in this process; recently the headcheese sign was recognized as a more specific for chronic-HP than the extensive mosaic attenuation. Several classification proposals and diagnostic models have been advanced by different groups, with no prospective validation. Therapeutic options for HP have been limited to antigen avoidance and immunosuppressant drugs over the last decades. Several questions about this condition remain unanswered and there is a need for more studies.

Sweet's syndrome, or acute febrile neutrophilic dermatosis, occurs in association with autoimmune diseases such as Hashimoto's thyroiditis but is rare in Graves' disease, in which all cases are induced by propylthiouracil (PTU). We report a case of Sweet's syndrome in a patient with Graves' disease treated with methimazole (MMI) during three weeks. A 34-year-old man presented with the acute onset of high fever, skin rashes on the whole body, arthralgia, and acroparesthesia. Laboratory results showed leukocytosis and elevated C-reactive protein. MMI first stopped and antibiotics and antihistamine therapy started, but his symptoms dramatically improved after oral prednisolone. Graves' disease has again been treated by MMI because of his aggravated ophthalmopathy. After one year of retreatment with MMI, there has been no recurrence of Sweet's syndrome, supporting that Sweet's syndrome in this case was not related to MMI exposure. To our knowledge, this is the first report of Sweet's syndrome associated with Graves' disease per se but not PTU or MMI use.

This case report is a unique case of solar retinopathy following antidepressant-induced mydriasis and highlights the need for comprehensive ophthalmic evaluation in patients treated with medications having mydriatic effects. A 49-year-old female patient who had received long-term antidepressant therapy presented with bilateral visual impairment after prolonged sun exposure. Fundoscopy confirmed solar retinopathy, which was attributed to drug-induced mydriasis. Medication adjustments and sun protection strategies led to full visual recovery, underscoring the importance of interdisciplinary awareness. This case emphasizes the challenges associated with the simultaneous management of psychiatric and ophthalmic conditions and highlights the need for routine ophthalmic evaluation of patients prescribed antidepressants with reported ocular side effects.

Hepatitis B virus (HBV) reactivation associated with various therapeutic interventions is a significant cause of morbidity and mortality among patients with current or resolved HBV infection. Since no curative treatment for HBV infection is currently available, a large number of individuals in the general population are at risk for HBV reactivation. Populations vulnerable to HBV reactivation include those currently infected with HBV or those who have had past exposure to the virus. The potential consequences of HBV reactivation are particularly concerning when these populations undergo anti-cancer chemotherapy, immunosuppressive or immunomodulatory therapies for managing various malignancies, rheumatologic diseases, inflammatory bowel disease, or undergo solid-organ or hematologic stem cell transplantation. This article aims to increase awareness of HBV reactivation and to elucidate the mechanisms and risks associated with HBV reactivation in various clinical settings.

Objective: The aim of this systematic literature review is to analyze the psychosocial interventions for children and adolescents after disasters. Methods: We conducted a review of the extant research literature from 1991 to 2015 via a comprehensive search of the MEDLINE, EMBASE, Cochrane CENTRAL, PubMed and PsyclNFO databases. The keywords employed in this research included: 'child', 'adolescent', 'youth', 'disaster', 'posttraumatic', 'psychosocial', 'therapy' and 'intervention'. The researchers followed the PRISMA guidelines. A total of 850 articles were screened for their eligibility and fifty-nine were found to meet the study criteria. The final data analysis was performed based on the disaster type, study design, type of intervention, sample size, age, school grade, number of sessions, setting of intervention delivery, providers, approach and parent involvement. Results: Countries worldwide have experienced various kinds of disasters, including earthquakes, hurricanes, vessel accidents, tornados, tsunamis, volcanic eruptions, war, fire, terrorism, and traffic accidents. The types of psychosocial intervention that were conducted after these disasters included: psychological first aid, psychological debriefing, psychoeducation, trauma focused cognitive behavior therapy, eye movement desensitization reprocessing, prolonged exposure therapy, group play therapy and arts therapy, project interventions, school-based interventions and web-based interventions. Conclusion: The findings of the systematic literature review suggest that an appropriate psychosocial intervention could be utilized as evidence-based mental health treatment for children and adolescents after disasters.

Metallo-${\beta}$-lactamase (MBL) can hydrolyze all ${\beta}$-lactams except monobactams and frequently coexists with various antibiotic resistance genes such as aminoglycoside resistance, sulfonamide resistance gene, etc. Therefore, the effective antibiotics against infections by these bacteria are markedly limited or can't even be found. We tried to search in-vitro antimicrobial combinations with synergistic effects for a VIM-2 type MBL producing Pseudomonas aeruginosa, isolated from clinical specimen. On the selection of antibiotic combinations with synergistic effects, we performed a one disk synergy test, modified Pestel's method, in agar without aztreonam (AZT). The bacteriostatic synergistic effects of this tests were scored as $S_1$ (by susceptibility pattern in agar without antibiotics), $S_2$ (by the change of susceptibility in agar with or without antibiotics) and $S_3$ ($S_1$ + $S_2$) and was classified into weak (1 point), moderate (2 points) and strong (3 points) by $S_3$ score. Subsequently, we carried out the time-killing curve for the antibiotic combinations with the strong synergistic bacteriostatic effect. One VIM-2 type MBL producing P. aeruginosa confirmed by the PCR showed all resistance against all ${\beta}$-lactams except AZT, aminoglycoside and ciprofloxacin. In the one disk synergy test, this isolate showed a strong bacteriostatic synergistic effect for the antibiotic combination of AZT and piperacillin-tazobactam (PIP-TZP) or AZT and amikacin (AN). On the time-killing curve after six hours of incubation, the colony forming units (CFUs/mL) of this bacteria in the medium broth with both combination antibiotics were decreased to 1/18.7, 1/17.1 of the least CFUs of each single antibiotics. The triple antibiotic combination therapy including AZT, PIP-TZP and AN was shown to be significantly synergistic after 8 hrs of exposure. In a VIM-2 MBL producing P. aeruginosa with susceptibility for AZT, the triple antibiotic combination therapy including AZT, PIP-TZP and AN may be considered as an alternative antibiotics modality against the infection by some MBL type. But the antimicrobial combination therapy for many more MBL producing isolates is essential to know as soon as possible for the selection of effective treatment against the infection by this bacteria.

국내 대학병원에서 분리되어 imipenem 에 대한 최소억제농도가 $8{\mu}g/ml$ 이상인 51개의 포도당비발효 그람음성 간균들 중 metallo-${\beta}$-lactamase (MBL)을 생성하는 균주들을 분리하고, 그들 중에서 내성이 강한 Pseudomonas aeruginosa에 대한 항균제 병합요법의 효과를 알아보기 위하여 상승효과를 보이는 항균제 조합을 찾아보았다. 9개의 균주(Pseudomonas aeruginosa 2주 및 Achromobacter xylosoxidans subsp. xylosoxidans 7주)가 MBL 양성을 나타냈으며, PCR 결과 9주 모두에서 $bla_{VIM-2}$ 유전자가 관찰되었다. 이들 중에서 P. aeruginosa DK569는 aztreonam (MIC; $8{\mu}g/ml$)을 제외하고 실험한 모든 ${\beta}$-lactam 항균제, aminoglycoside, ciprofloxacin에 내성을 보여 aztreonam 함유 배지를 이용하여 상승효과률 보이는 항균제를 찾고자 하였다. One disk synergy test 에서 선별된 항균제 조합을 이용하여 생존률 검사 실험을 한 결과, aztreonam (AZT)와 piperacillin-tazobactam (TZP)의 병합은 항균제 노출 6시간 후에 AZT 또는 TZP의 단독 항균제 노출시 보다 균수가 1/18.7로 감소하였다. 그리고 AZT와 amikacin (AN)의 병합에서도 항균제 노출 6 시간 후에 AZT 또는 AN의 단독항균제의 투여보다 균수가 1/17.1 로 감소하였다. 결국 위 두 조합은 의미있는 상승효과를 보이지 못하여 위 세 항균제를 조합하여 실험하였다. 위의 세 항균제를 병합하였을 때 항균제 노출 8시간 후에 AZT, TZP 및 AN의 단독 투여에 비하여 병합요법에 의해 균수가 1/183.3 로 감소하여 의미있는 상승효과를 보였다. 이 결과는 치료가 쉽지 앓은 MBL 생성균에 의한 감염에 대한 치료에 AZT, TZP 및 AN의 세 가지 항균제 병합요법이 유용할 것이라는 것을 의미한다.
