For the purpose of assessing the utility and cautionary aspects of pulse oximetry of which use is rapidly increased, it was applied to the maladaptive child patients with sedative drugs and evaluated the results. When pulse oximeter was used alone for vital sign monitoring, it was thought impossible to exclude the false alarm or false silence by various causes. To minimize or remove these misunderstanding, operators should have a extensive knowledge not only on the factors affecting the operation of this apparatus but also on the potential of misoperation. To review the present status of increasing risk of hypoxia during the sedation, it was thought unreasonable to solely depend upon this apparatus for vital sign monitoring. By combining with more accurate and auxiliary monitoring devices, pulse oximetry will be of greater value and can meet the clinical needs and conveniences.

Headache is a common complaint in pediatric office practices as well as in children presenting to emergency departments. Children who complain of headache usually are brought to medical attention by their parents, who seek reassurance that the headaches are not a sign of a serious illness. The etiologies of headache range from school problems to brain tumors. A history taking, physical examination, and appropriate diagnostic testing will enable to distinguish primary headaches from those of a secondary etiology. The clinical, neuroimaging, and laboratory evaluation of the child with headache are reviewed here.

Acute pulmonary embolism (PE) is a life-threatening disease that manifests with cardiorespiratory symptoms. Syncope can be a rare, but warning sign of PE. We report a case of a 49-year-old male diagnosed with PE who presented with recurrent syncope prior to typical cardiorespiratory symptoms. His computed tomography pulmonary angiogram revealed bilateral PE. Syncope can be a rare clinical symptom of PE, but considering lethality of the disease, a differential diagnosis of PE should be considered in patients with recurrent syncope.

Background: Tarsal tunnel syndrome (TTS) is an entrapment neuropathy of the tibial nerve within fibrous tunnel on the medial side of the ankle. The most common cause of TTS is idiopathic. This is a retrospective study to define the electrophysiological characteristics of idiopathic TTS. Methods: We reviewed the medical and electrophysiological records of consecutive patients with foot sensory symptoms referred to electromyography laboratory. Inclusion of patients was based on clinical findings suggestive of TTS. Among them, patients with any other possible causes of sensory symptoms on the foot were excluded. Control data were obtained from 19 age-matched people with no sensory symptoms or signs. Routine motor and sensory nerve conduction study (NCS) including medial plantar nerve (MPN) using surface electrodes were performed. Result: Twenty one patients (13 women, 8 men, 9 unilateral, 12 bilateral) were enrolled to have idiopathic TTS (total 31 feet). Tinel's sign was positive in 16 feet (51.6%) of TTS and four feet (10.5%) in control group. The statistically significant electrophysiological parameter was difference of sensory conduction velocity (SCV) between sural nerve and MPN. Amplitude of sensory nerve action potential and SCV of MPN were not different significantly between idiopathic TTS feet and controls. Conclusion: Bilateral development in idiopathic TTS was more common. Tinel's sign and difference of SCV between sural nerve and MPN may be helpful for the diagnosis of idiopathic TTS.

Objective: To evaluate the interobserver agreement, diagnostic value, and associated clinical factors of automated breast ultrasound (ABUS) coronal features in differentiating breast lesions. Materials and Methods: This study enrolled 457 pathologically confirmed lesions in 387 female (age, 46.4 ± 10.3 years), including 377 masses and 80 non-mass lesions (NMLs). The unique coronal features, including retraction phenomenon, hyper- or hypoechoic rim (continuous or discontinuous), skipping sign, and white wall sign, were defined and recorded. The interobserver agreement on image type and coronal features was evaluated. Furthermore, clinical factors, including the lesion size, distance to the nipple or skin, palpability, and the histological grade were analyzed. Results: Among the 457 lesions, 296 were malignant and 161 were benign. The overall interobserver agreement for image type and all coronal features was moderate to good. For masses, the retraction phenomenon was significantly associated with malignancies (p < 0.001) and more frequently presented in small and superficial invasive carcinomas with a low histological grade (p = 0.027, 0.002, and < 0.001, respectively). Furthermore, continuous hyper- or hypoechoic rims were predictive of benign masses (p < 0.001), whereas discontinuous rims were predictive of malignancies (p < 0.001). A hyperechoic rim was more commonly detected in masses more distant from the nipple (p = 0.027), and a hypoechoic rim was more frequently found in large superficial masses (p < 0.001 for both). For NMLs, the skipping sign was a predictor of malignancies (p = 0.040). Conclusion: The coronal plane of ABUS may provide useful diagnostic value for breast lesions.

This study was attempted to be used as basic data for efficient clinical practice education operation by identifying differences in program outcomes before and after integrated clinical practice of nursing students. Data collection was conducted before and after 6 weeks of integrated clinical practice for 38 nursing college students from July 19 to September 10, 2021 with a single group pre- and post-design. The collected data were analyzed by frequency, Wilcoxon sign rank, and Pearson correlation using SPSS/Win 23.0. After the integrated clinical practice, 1st program outcomes(Care integration)(Z=-4.63, p<.001), 2nd(Core practice)(Z=-3.99, p<.001), 6th(Critical thinking)(Z=-3.60, p<.001) and 11th(Research practice)(Z=-2.76, p=.005) increased significantly compared to before practice. Since integrated clinical practice was found to be an effective practice to improve program outcomes, it is suggested to actively utilize it as a strategy for improving program outcomes.

Objective: This study aimed to determine the predictive performance of non-contrast CT (NCCT) signs for hemorrhagic growth after intracerebral hemorrhage (ICH) when stratified by onset-to-imaging time (OIT). Materials and Methods: 1488 supratentorial ICH within 6 h of onset were consecutively recruited from six centers between January 2018 and August 2022. NCCT signs were classified according to density (hypodensities, swirl sign, black hole sign, blend sign, fluid level, and heterogeneous density) and shape (island sign, satellite sign, and irregular shape) features. Multivariable logistic regression was used to evaluate the association between NCCT signs and three types of hemorrhagic growth: hematoma expansion (HE), intraventricular hemorrhage growth (IVHG), and revised HE (RHE). The performance of the NCCT signs was evaluated using the positive predictive value (PPV) stratified by OIT. Results: Multivariable analysis showed that hypodensities were an independent predictor of HE (adjusted odds ratio [95% confidence interval] of 7.99 [4.87-13.40]), IVHG (3.64 [2.15-6.24]), and RHE (7.90 [4.93-12.90]). Similarly, OIT (for a 1-h increase) was an independent inverse predictor of HE (0.59 [0.52-0.66]), IVHG (0.72 [0.64-0.81]), and RHE (0.61 [0.54-0.67]). Blend and island signs were independently associated with HE and RHE (10.60 [7.36-15.30] and 10.10 [7.10-14.60], respectively, for the blend sign and 2.75 [1.64-4.67] and 2.62 [1.60-4.30], respectively, for the island sign). Hypodensities demonstrated low PPVs of 0.41 (110/269) or lower for IVHG when stratified by OIT. When OIT was ≤ 2 h, the PPVs of hypodensities, blend sign, and island sign for RHE were 0.80 (215/269), 0.90 (142/157), and 0.83 (103/124), respectively. Conclusion: Hypodensities, blend sign, and island sign were the best NCCT predictors of RHE when OIT was ≤ 2 h. NCCT signs may assist in earlier recognition of the risk of hemorrhagic growth and guide early intervention to prevent neurological deterioration resulting from hemorrhagic growth.

A prevalence of temporomandibular disorders(TMD) based on the clinical sign and symptom in 155 patients were investigated. History taking with interview chart and clinical examination were performed. Age and gender of the patients, duration of TMD, location of pain, joint sound, limitation of mouth opening and more detailed diagnostic name were identified. The results of this study were as follows: 1. TMD was more prevalent in female than in male. TMD was the most prevalent at the age of 20s and decreased with age. 2. Acute TMD was more prevalent than chronic one. 3. About ninety percent of TMD patients had pain. Pain had mainly a unilateral origin. Muscle pain was mainly related with the masseter muscle. 4. Joint sound was identified in about fifty-six percent of the TMD patients and unilateral joint sound was more prevalent than bilateral one. 5. Limitation of mouth opening was observed in about forty percent of the TMD patients. 6. In TMD patients, muscle dysfunction was the most prevalent one. In muscle disorders local muscle soreness was the most prevalent one. In joint disorders, capsulitis was the most prevalent one. In muscle-joint disorders, trigger point pain with retrodiscitis was the most prevalent one.
