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.

In growing children it is frequently found that dental maturation is strongly influenced by the growth rate of maxilla or mandible. If there is evidence to prove this, it might be utilized as a criterion in the early diagnosis of skeletal malocclusion, even before the object's real skeletal features are yet revealed. The purpose of this study was to find out if the difference of dental maturation in over-grown mandible in children with skeletal Class III has any relationship with some skeletal features of mandible. 50 patients in Hellman dental age IIIA with normal occlusion and Class III malocclusion of mandibular over-growth type respectively were selected as study objects. The age estimation was performed on maxillary and mandibular teeth, eruption rate of the 2nd molars of each group have been measured on panoramic radiography, and the differences in dental age of the upper and lower jaw were analyzed under Demirijian's method. The results were as follows: The difference of dental age of maxillary and mandibular teeth between the two groups was 0.66 and 1.20 years respectively, with a higher difference in the experimental group (p < 0.05). The difference of eruption rate of the maxillary and mandibular second molar was not found between two group (p >0.05).

The aim of this study was to evaluate QLF (quantitative light-induced fluorescence) technology for the caries detection in primary teeth and validate the relationships between the cavity volume of carious lesions and QLF analysis results. Total 125 tooth surfaces include 53 occlusal surfaces, and 72 proximal surfaces were investigated with the portable QLF device for detection of dental caries in primary molars. Micro-CT radiograph was also performed to classify carious lesions and calculate the cavity volume. QLF showed good accuracy and reliability (sensitivity 0.75 - 0.94, specificity 0.82 - 0.95, and AUROC 0.88 - 0.98) for the caries detection in primary teeth except 𝚫R average results of proximal caries which showed relatively low values. Statistically significant relationships were found between 𝚫F average, QS-Index and the cavity volume according to Spearman rank-order correlation coefficients (r = 0.805 - 0.832, p < 0.001). QLF detection method would be a harmless and reliable way for children to diagnose dental caries without the concern about radiation exposure.

A lung hernia, defined as the protrusion of pulmonary tissue and pleural membranes through a defect in the thoracic wall, is a rare event. It can be congenital or acquired, and cervical, thoracic, or diaphragmatic in location. We report the rare occurrence of a congenital atraumatic lung herniation through the azygoesophageal recess. An 8-month-old male infant, who was born at 35 weeks gestation, had a chronic cough. Chest radiography showed haziness at the right lower lobe of the lung (RLL). Chest computed tomography (CT) revealed herniation of the RLL through the azygoesophageal recess. If persistent unilateral haziness is observed on chest radiography, the possibility of lung herniation should be considered.

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.
