The detection of foreign bodies in the upper-aerodigestive tract is a fairly frequent event and can occur in various areas and for various reasons. In rare cases, foreign bodies can simulate a neoplasia. We evaluated similar cases during emergency regimen with an oral cavity mucosal lesion, causing lockjaw, sore throat, dysphagia, and swelling of the submandibular and laterocervical region. Physical examination revealed an extensive mucosal ulceration in the floor of the mouth and the lateral surface of the tongue, comparable to oral cancer. During a second, more accurate assessment, a partially deteriorated iron supplement tablet was found embedded in a mucosal pocket. After removing the tablet, gradual normalization of the tissue was observed without any sequelae. This is one of the many reasons why it is advisable and useful in cases of oral lesions to collect a detailed medical history and to perform an accurate clinical evaluation, including inspection and palpation of the lesion, before proceeding to further diagnostic assessments, especially in elderly patients taking many medications. However unlikely, it is possible that difficulty in swallowing pills or tablets could generate tumorlike lesions.

The present study is to determine the toxicity of the fungi isolated from foodstuffs by observing the ultrastructural changes in the mouse liver cells. The results as follows: 1. The toxin-producing fungi were screened by the methods of toxin-screening test(cyto-toxicity test against to HeLa cells and thin layer chromatography). 2. All of the experimental animals treated with isolated fungi were observed the focal necrosis and inflammatory infiltration of liver parenchymal cells. 3. It showed the cytoplasmic changes, such as dilatation of rough endoplasmic reticulum (RER), swelling of mitochondria (mi). increased number of lipid droplet (li) and glycogen (gl), detachment of ribosomes (ri) by observing the electron microscopy. 4. Nuclear and nucleolar alteration were also noted the segregation of nucleolar element and irregularity of nuclear envelopes. 5. As a mass screening, the cytotoxicity test using HeLa cells and thin layer chromatography are feasible methods to detection of the mycotoxin producing fungi from various sources.

We report the case of a 64-year-old man with superior vena cava (SVC) syndrome due to tumor thrombus from recurrent hepatocellular carcinoma (HCC). He presented with new onset of facial swelling for 10 days. HCC was detected ten years ago. He has undergone repeated transcatheter arterial embolization (TAE) and chemotherapy. Chest computed tomography (CT) demonstrated tumor thrombus in the SVC extending to right atrium. He underwent whole body F-18 fluorodeoxyglucose(FDG) positron emission tomography/computed tomography (PET/CT) scanning for assessing the effect of TAE in HCC. F-18 FDG PET/CT showed increased uptake in the residual liver mass indicating viable tumor. There was another intense F-18 FDG accumulation in SUV extending to right atrium to suggest tumor thrombus. This case illustrates that F-18 FDG PET/CT is useful to identification of distant metastases as well as assessment of response to therapy in long-term survival HCC patients.

Bone pain in a child could be associated with cancer as an initial manifestation of the disease. The childhood malignancies that frequently present bone pain are leukemia, neuroblastoma, and primary bone tumors such as osteosarcoma and Ewing sarcoma. Persistent bone or joint pain associated with swelling, mass, or limitation of motion implies underlying serious causes. Systemic manifestations such as lymphadenopathy, hepatosplenomegaly, fever, fatigue, night sweat, and laboratory abnormalities are also suggestive of malignancy. The index of suspicion tends to be low since less than 1% of children who complain of bone pain are diagnosed as cancer. Nonetheless, pediatricians should be alert to the possibilities of cancer since early detection and prompt treatment might reduce mortality.

The use of intravenous catheters are occasionally complicated by intravascular fragments and swelling of the catheter fragments. We present a patient in whom an intravenous catheter fragments was retrieved from the dorsal metacarpal vein following its incidental CT examination detection. The case of demonstrates the utility of microscopy and multi-detector CT in localizing small of subtle intravenous catheter fragments as a human error. A case of IV catheter fragments in the metacarpal vein, in which reproducible and microscopy data allowed complete localization of a missing fragments and guided surgery with respect to the optimal incision site for fragments removal. These reproducible studies may help to determine the best course of action and treatment for the patient who presents with such a case.

Purpose: To examine the details of lymphedema, upper limb morbidity, and its self management in women after breast cancer treatment. Methods: Using a cross-sectional survey design, 81 women were recruited from a university hospital. Lymphedema was detected by a nurse as a 2-cm difference between arm circumferences at 6 different points on the arm. Degrees of pain, stiffness, and numbness were scored using a drawing of upper limb on a 0~10 point scale. Aggravating conditions and self-management for lymphedema were also recorded. Results: The mean age of the participants was 52.5 years; the average time since breast surgery was 29.7 months. Histories of modified radical mastectomy (55%) and lymph node dissection (81%) were noted. Lymphedema was found in 59% of women, then pain and stiffness were prevalent most at upper arm while numbness was apparentat fingers, and the symptom distress scores ranged 3.9~6.7. Women experienced aggravated arm swelling after routine housework with greatly varied duration. Self-management was conservative with a wide range of times for the relief of symptoms. Conclusion: Lymphedema education for women with breast cancer should be incorporated into the oncologic nursing care system to prevent its occurrence and arm morbidity. Risk reduction guidelines, individually tailored self-care strategies, and self-awareness for early detection need to be refined in clinical nursing practices.

According to most experts and health workers, a living creature's body heat is little understood and crucial in the identification of disorders. Doctors in ancient medicine used wet mud or slurry clay to heal patients. When either of these progressed throughout the body, the area that dried up first was called the infected part. Today, thermal cameras that generate images with electromagnetic frequencies can be used to accomplish this. Thermography can detect swelling and clot areas that predict cancer without the need for harmful radiation and irritational touch. It has a significant benefit in medical testing because it can be utilized before any observable symptoms appear. In this work, machine learning (ML) is defined as statistical approaches that enable software systems to learn from data without having to be explicitly coded. By taking note of these heat scans of breasts and pinpointing suspected places where a doctor needs to conduct additional investigation, ML can assist in this endeavor. Thermal imaging is a more cost-effective alternative to other approaches that require specialized equipment, allowing machines to deliver a more convenient and effective approach to doctors.

Nasopalatine duct cysts (NPDCs), the most common non-odontogenic cysts of maxilla, are often incidental findings on diagnostic imaging. When symptomatic, they usually present as a painless swelling with possible fistula. Conventional radiography shows a round-to-ovoid or heart-shaped radiolucency between the roots of central maxillary incisors. While the radiographic features of NPDCs in X-ray-based modalities have been well described, their magnetic resonance imaging (MRI) features have rarely been reported. Developments in dental MRI in recent years and the introduction of various dental MRI protocols now allow a wide range of applications in dental medicine. MRI is becoming an important tool for the detection and diagnosis of incidental or non-incidental dentomaxillofacial cysts. This report presented and discussed the characteristics of 2 NPDC cases visualized on MRI using both conventional and newly implemented specific dental MRI protocols with a novel 15-channel mandibular coil, demonstrating the use of these protocols for radiation-free maxillofacial diagnoses.

Klebsiella pneumoniae is an uncommon cause of septic arthritis in adults. However, late detection can cause serious complications, including joint destruction and immobility. The purpose of this study was to report a case of successfully treated septic arthritis of the hip joint (SAHJ) caused by K. pneumoniae. A 49-year-old female patient presented to our hospital with fever and progressive severe pain in the right hip area. Although there was no abnormality on plain radiographs, ultrasonography revealed diffuse swelling of the right hip joint. Under ultrasonography guidance, the hip joint fluid was aspirated, and Gram staining and culturing were performed. The patient's pain was significantly reduced after the joint aspiration. The Gram staining and culturing revealed gram-negative bacilli, which were subsequently identified as K. pneumoniae. According to the results, systemic intravenous antibiotic (ceftriaxone) was administered without complications, and the patient was discharged on oral antibiotic (ciprofloxacin). Clinical cases of septic arthritis of the knee or sacroiliac joint have been occasionally reported in adults, but cases of SAHJ are rare. Moreover, K. pneumonia-induced SAHJ has not been reported to date. Therefore, we report this very rare case and its successful treatment.

Background: Pulmonary paragonimiasis is a subacute to chronic inflammatory disease of the lung caused by lung flukes that result in prolonged inflammation and mechanical injury to the bronchi. However, there are few reports on the bronchoscopic findings of pulmonary paragonimiasis. This report describes the bronchoscopic findings of pulmonary paragonimiasis. Methods: The bronchosocpic findings of 30 patients (20 males, median age 50 years) with pulmonary paragonimiasis between May 1995 and December 2007 were reviewed retrospectively. Results: The diagnoses were based on a positive serologic test results for Paragonimus-specific antibodies in 13 patients (43%), or the detection of Paragonimus eggs in the sputum, bronchial washing fluid, or lung biopsy specimens in 17 patients (57%). The bronchoscopic examinations revealed endobronchial lesions in 17 patients (57%), which were located within the segmental bronchi in 10 patients (59%), lobar bronchi in 6 patients (35%) and main bronchi in 1 patient (6%). The bronchoscopic characteristics of endobronchial lesions were edematous swelling of the mucosa (16/17, 94%) and mucosal nodularity (4/17, 24%), accompanied by bronchial stenosis in 16 patients (94%). Paragonimus eggs were detected in the bronchial washing fluid of 9 out of the 17 patients with endobronchial lesions. The bronchial mucosal biopsy specimens showed evidence of chronic inflammation with eosinophilic infiltration in 6 out of 11 patients (55%). However, no adult fluke or ova were found in the bronchial tissue. Conclusion: Bronchial stenosis with mucosal changes including edematous swelling and mucosal nodularity is the most common bronchoscopic finding of pulmonary paragonimiasis.
