단순 흉부 X-선 사진은 흉곽내에 공기를 함유하고 있는 폐실질, 심장과 대혈관을 포함한 연부조직, 그리고 흉곽을 이루는 골격 등의 다양한 조직으로 이루어진 3차원적인 해부학적 구조물을 X-선 film이라는 2차원적 평면에 흑백의 음영으로 표현하는 검사이다. 뿐만아니라 이들 구조물들이 전후, 좌우로 겹쳐져 있어 병변이 쉽게 가려질 수 있고, 폐실질 질환 뿐만 아니라 심장 질환 또한 폐실질의 변화를 유발시킬 수 있으므로, 단순히 각 질환의 X-선 소견에 대한 지식을 습득하는 것보다는 병인과 해부학적인 지식에 대한 이해를 기본으로 X-선 판독에 임하는 것이 중요하다. 또한 환자들의 임상 증상과 부합되지 않는 X-선 소견이 관찰되거나, 치료 도중 임상 경과와 판독소견이 일치되지 않는다면 방사선과 전문의와의 긴밀한 의견교환이 진단과 치료에 중요하리라 생각된다.

Vulvar agenesis in an eight-month-old toy poodle dog is described. Urinary incontinence and dysuria were the main clinical signs. The morphology of the urogenital system was assessed with contrast radiography. The constructers of lower urinary tract and reproductive system except for the vulva were normal features. Through episiostomy, a perineal stoma, resembling a vulva, was created, resulting in complete resolution of the clinical signs.

Central giant cell lesions are rare, benign, osteolytic, pseudocystic, solitary, localized lesions that are common in the skeletal structure, but less so in the maxillofacial region. Furthermore, to perform panoramic radiography and cone-beam computed tomography, it is necessary to prepare patients properly and to position their heads carefully. However, this can be difficult in pediatric patients, who may be anxious. In this report, we describe the case of a central giant cell lesion of the mandible in a 2-year-old girl that was evaluated with multidetector computed tomography.

A 7-year-old girl visited the Samsung Medical Center emergency room for primary tooth aspiration during primary tooth extraction under conscious sedation with N₂O. The patient showed no signs of respiratory complications. Chest radiography and CT revealed a tooth in the right bronchi. Foreign body removal using rigid bronchoscopy was performed on the day of aspiration. With close monitoring of the airway in the pediatric ICU, extubation was performed the next day, and the patient was discharged the same day. The primary objective of this case report was to highlight the potential risk of aspiration associated with the use of N₂O gas for conscious sedation.

Chronic nonbacterial osteomyelitis(CNO) is histologically characterized by nonspecific osteitis. This inflammatory disorder, which lacks an infectious origin, typically presents with chronic pain and swelling at the affected site that can persist for months or even years. However, it is rare for CNO to affect the mandible. A 10-year-old girl presented with a primary complaint of pain in her left mandible. She had no significant medical or dental history. On examination, swelling was visible on the left buccal side, and imaging revealed radiolucent bone deterioration within the left mandible. This case report presents the radiological changes observed over a 12-year follow-up period. Variations in radiopacity, radiolucency, and periosteal reactions were noted periodically. This case highlights the radiological characteristics and findings that are crucial for the diagnosis of CNO, a condition for which no clear diagnostic criteria are currently available.

Background: In recent years, pediatric chronic sinusitis patients who don't respond with antibiotics are increasing, but there are a few reports on the herbal medicine therapy treating pediatric chronic sinusitis, so this report was studied. Objective: To demonstrate the effect of herbal medicine therapy in the chronic sinusitis before and after treatment using computed tomograpy (CT) and plain radiograpy. Materials and methods: Ninty patients (45 mail and 45 femail) treated in our hospital between February 1998 and August 1999 were studied. Ages ranged from 3 to 13 years (mean age :6.5 years). Sixty two patients had a underlyiing family history (allergy or sinusitis of parents or brothers), In the past history, 68 patients had asthma, allergy of milk, atopic dermatitis, bronchiollitis and irritable bowel syndrom. Illness period was from 10 days to 96 months (mean period:12.4 month). Duration of treatment were from 25 days to 200days (mean:96 days). To ascertain the efficacy of treatment, CT in the 42 and plain radiopgrapy in the 48 patients were checked out. In the CT, three images were obtained 2cm interval on the coronal and axial plan. CT findings of the chronic sinusitis were analyzed for mucoperiostal thickening before and after treatment using 4 grades;(normal, mild, moderate, severe). Normal was defined as below 3mm thickening of mucoperiosteum; mild was 3-5mm thickening; moderate was 5mm-1cm thickening; severe was above 1cm thickening. Plain radiograpy using Water's view provided maxillary sinus, anterior ethmoid sinus, frontal sinus. Normal was defined as simillar to density between sinus and oronasal cavity; mild was defined as generally increased density with no significant mucoperiosteal thickning; moderate was partial mucosal thickening without bony hypertropy; severe was total haziness with mucoperiosteal thickening. Gamihyunggyeyungyo-tang was administered mainly. Gamigwaghyangjeungki-san, Gamizwakwi-eum and Gamihyangso-san were administered for through oral route additional symptoms Results: Of the 90 patients, 84 patients showed complete recovery (93%), 4 patients showed no significant interval change(4%) and 2 patients were aggrevated (2%). Sixty patients were severe(67%) and 26 patients were moderate (29%), 4 patients were mild(4%) The duration of treatment was varied with patient conditions (91 days in average); severe were 101.7 days, moderate were 70 days and mild were 63 days. Fifty three patients with maxillary and ethmoid sinusitis were 114 days, 35 patients with maxillary sinusitis only were 71.5 days. Fifty eight patients with both maxillary sinusitis were 94.6 days, 26 patients with either maxillary sinusitis were 65 days. The symtoms of chronic sinusitis were nasal obstruction(75%), cough(69%), purulunt or mucosal discharge(62%), lymphoid follicle(54%), postnasal dripping(49%), headache(23%) and nose bleeding(22%). Conclusion: We know that herbal medicine therapy is the effective treatment of pediatric chronic sinusitis using plain radiograpy and CT. The duration of treatment may be significant assosiation with the location and degree of chronic sinusitis.

본 연구의 목적은 유치의 치아우식증 검사를 위한 정량형광분석(quantitative light-induced fluorescence, QLF) 기술의 유효성을 평가하고, 우식병소의 부피와 QLF 분석결과 사이의 상관관계를 확인하는 것이다. 치아우식증 검사를 위해 53개의 교합면 및 72개의 인접면을 포함한 총 125개의 유구치 치면을 휴대용 QLF 장비를 이용해 조사하여 유구치의 치아우식증을 확인하였다. 또한 치아우식증을 분류하고 우식병소의 부피를 계산하기 위해 micro-CT 방사선 검사를 시행하였다. 상대적으로 낮은 수치를 보였던 인접면 우식에 대한 𝚫R average 결과를 제외하면, QLF 분석결과는 유치의 치아우식증 진단에 대해 충분한 수준의 정확성과 신뢰도를 보였다(민감도 0.75 - 0.94, 특이도 0.82 - 0.95, AUROC 0.88 - 0.98). Spearman 상관분석 결과에서는 𝚫F average 및 QS-Index와 우식병소 부피 사이에 통계적으로 유의한 높은 상관성을 확인할 수 있었다(r = 0.805 - 0.832, p < 0.001). QLF 기술을 이용한 치아우식증 검사는 어린이의 치아우식증 진단에 있어 방사선 노출에 대한 걱정 없이 안전하게 사용 가능하고, 신뢰할 만한 방법이 될 수 있을 것이다.

Purpose: Chest radiography is often performed on patients hospitalized with typical clinical manifestations of bronchiolitis. We aimed to determine the proportion of subjects with pathologic chest radiographic findings and the clinical predictors associated with pathologic chest radiographic findings in young children admitted with the typical presentation of bronchiolitis. Methods: We obtained the following data at admission: sex, age, neonatal history, past history of hospitalization for respiratory illnesses, heart rate, respiratory rate, the presence of fever, total duration of fever, oxygen saturation, laboratory parameters (i.e., complete blood cell count, high-sensitivity C-reactive protein [hs-CRP], etc.), and chest radiography. Results: The study comprised 279 young children. Of these, 26 had a chest radiograph revealing opacity (n=24) or atelectasis (n=2). Multivariate logistic regression analysis showed that after adjustment for confounding factors, the clinical predictors associated with pathologic chest radiographic findings in young children admitted with bronchiolitis were elevated hs-CRP level (>0.3 mg/dL) and past history of hospitalization for respiratory illnesses (all P<0.05). Conclusion: The current study suggests that chest radiographs in young children with typical clinical manifestations of bronchiolitis have limited value. Nonetheless, young children with clinical factors such as high hs-CRP levels at admission or past history of hospitalization for respiratory illnesses may be more likely to have pathologic chest radiographic findings.
