This is an autopsy case of a 6 month old girl who suddenly died of respiratory distress during sleep. She had suffered from mild but frequent episodes of common cold and was treated for eczema for several days. At autopsy, the heart was enlarged and weighed 100 gm. A firm and gray-white tumor, measuring 4.5 x 3.8 x 2.8 cm, was located in the interventricular septum and encroached upon the wall of left ventricle. The mass was well demarcated but was not encapsulated. Neither necrosis nor calcification was present. Microscopically the tumor was composed of haphazardly arranged bundles of collagen fibers and fibroblasts. Myocardial cells are intermingled with the fibroblasts at the margin of the tumor. Massive edema of the lung and congestion of the liver and spleen were pronounced.

The mutation of p53 tumor suppressor gene is the most common genetic variation of primary malignant tumors. The occurrence, progression and reaction for medical management of cancers can be different according to the characteristics of p53 gene, even if they are same kinds of malignant tumors. In this study, the property of p53 gene in 4 kinds of squamous cell carcinoma cell lines were investigated by using immunocytochemistry, PCR-SSCP, sequencing and Western blot methods. As a result, p53 mutation detected in 3 kinds of squamous cell carcinoma cell lines. Namely, it is found that T in codon 176 changed to A, and G in codon 281 changed to A in KUMA3 cell lines; CC in codon 241 changed to TT in KUMA4 cell lines; G in codon 266 changed to T in KUMA6 cell lines. In single nucleotide polymorphism of codon 72 of p53 gene, the genetic variations are Arg/Pro heterozygote in KUMA3 and KUMA4 cell lines; Arg/Arg homozygote in KUMA5 cell lines; Pro/Pro homozygote in KUMA6 cell lines. These results will provide useful data for p53 gene researches of various squamous cell carcinomas.

3.Effects of Active Mandibular Exercise for Mouth Opening Limitation Patients after Maxillomandibular Fixation Release: A Non-Randomized Controlled Trial
Journal of Korean Academy of Nursing 2018;48(1):26-37
PURPOSE: The aim of this study was to evaluate the effects of active mandibular exercise (AME) in patients with limited mouth opening after maxillomandibular fixation (MMF) release. METHODS: The study used a quasi-experimental, nonequivalent control group and a pre test-post test design. Sixty-two patients with Maxillomandibular Fixation Release were assigned to the experimental (n=31) or control group (n=31). The AME was performed in the experimental group for 4 weeks. The exercise AME consisted of maximal mouth opening, lateral excursion and protrusive movement. These movements were repeated ten times a day. After the final exercise of the day, the number of tongue blades used for mouth opening was noted. The effect of AME was evaluated after MMF release at different time intervals: a) immediately, b) after 1 week, c) after 2 weeks, d) after 4 weeks, and e) after 12 weeks. The exercise was assessed using the following criteria: a) mandibular movements, b) pain scores associated with maximal mouth opening, c) discomfort scores associated with range of movement, and d) daily life activities that involve opening the mouth. RESULTS: The experimental group showed significant improvement regarding the range of mandibular movements (maximal mouth opening (F=23.60, p < .001), lateral excursion to the right side (F=5.25, p=.002), lateral excursion to the left side (F=5.97, p=.001), protrusive movement (F=5.51, p=.001)), pain score (F=39.59, p < .001), discomfort score (F=9.38, p < .001). Daily life activities that involve opening the mouth were more favorable compared to those in the control group. CONCLUSION: The AME in patients after MMF release is helpful for increasing mandibular movement range, decreasing pain and discomfort, and improving day life activities that involve opening the mouth. Therefore, AME is highly recommended as an effective nursing intervention.

PURPOSE: The purpose of this study was to identify status and characteristics of patients who have been readmitted to ICU, and to analyze risk factors associated with the readmission to ICU within 48hours.METHODS: Data were collected from patient's electronic medical reports from one hospital in B city. Participants were 2,937 patients aged 18 years old or older admitted to the ICU. Data were analyzed using odd ratios (ORs) from multivariate logistic regressions.RESULTS: 2.2% of the 2,937 patients were early readmitted to ICU. Risk factors for early readmission to ICU were existence of respiratory disease, use of mechanical ventilator, and duration of hospitalization (longer).CONCLUSION: The assessment on the respiratory system of the patient who will be discharged from the ICU was identified as an important nursing activity. Therefore, the respiratory system management and education should be actively conducted. In addition, early ICU readmission may be prevented and decreased if a link was built to share the information on patient condition between the ICU and general wards.

A 63-year-old Korean man presented with generalized, asymptomatic, discrete papules and coalescent annular plaques for one year. Interestingly, the patient complained of conjunctival congestion, concurrently with aggravation of the skin lesion. Histopathologic findings of the skin lesion and conjunctiva revealed giant cells engulfing fragmented elastic fibers, and a diagnosis of actinic granuloma with ocular involvement was made. Ten months later, the patient revisited with a two-week history of bilateral temporal headache, neck pain, intermittent jaw claudication, and blurred vision. Biopsy of the temporal artery confirmed the clinical diagnosis of temporal arteritis. Both actinic granuloma and temporal arteritis show similar pathologic process, and this case supports the hypothesis that actinically degenerated elastic tissue is likely to be the antigenic basis of actinic granuloma of the skin and temporal arteritis.

The macrocystic form of serous cystadenoma of the pancreas is an uncommon benign neoplasm composed of few, relatively large cysts that are lined by uniform, glycogen-rich, cuboidal epithelial cells. We report here on two cases of pathologically proven macrocystic serous cystadenoma of the pancreas in a 45-year-old female patient and a 53-year-old female patient. Both these cysts were lined by low cuboidal epithelia without any evidence of mucin production. There was also no evidence of pancreatitis. These tumors were radiologically suspected as being mucinous cystic neoplasm or pseudocysts. Although the microscopic and immunohistochemical studies of the macrocystic variant are not different from the conventional serous microcystic cystadenoma, their unusual macroscopic features can lead to confusion for the clinicians and radiologists.

PURPOSE: Pathologic aerophagia (PA) may lead to bowel perforation or volvulus in mentally retarded patients. The authors investigated the effects of clonazepam on the management of PA in children with severe to profound mental retardation (MR). METHODS: This study was undertaken as a retrospective case analysis of 21 PA patients with MR who were followed for over 12 months and diagnosed as having PA. Patients were assigned to two management groups, that is, to a clonazepam randomized open-labeled, treatment group or a reassurance group. The following were recorded and analyzed; age, response, remission rate to clonazepam treatment, and the side effect of clonazepam. It was defined positive response (response+) as being symptom-free for a whole week within 1 month of commencing treatment and remission(+) as being symptom-free for a whole month within 6 months of treatment. RESULTS: The average age of the 21 PA children with MR was 10 years and 13 patients were female. Symptom duration before diagnosis of PA was 7 months. Clinical features of the clonazepam-trial group (n=11) and the reassurance group (n=10) were non-significantly different. Response(+) was achieved by 2 patients (18.2%) in the clonazepam-trial group and by no patient in the reassurance group. Remission(+) was achieved by 6 patients (54.5%) in the clonazepam-trial group and by one patient (10%) in the reassurance group (p=0.040). CONCLUSION: When PA children with MR with severe bowel distention are considered for surgical treatment to prevent acute abdomen, a trial of clonazepam could be recommended.

A newly developed third generation enzyme immunoassay(Lucky HCD 3.0 EIA) for hepatitis C virus(HCV) antibodies was added with the envelope(E1E2)/NS4 fusion proteins and expanded NS5 proteins as well as the core/NS3 fusion proteins. Authors evaluated the HCD 3.0 EIA with the previously available second generation EIA(HCD 2.0) in 10,435 Red Cross blood donors. Among 10,435 donors who were screened for the presence of HCV antibodies by HCD 2.0 assay, 22(0.21%) sera were repeatedly reactive. All of these sera were tested for further testing. Only 13 of all tested sera were reactive by HCD 3.0 EIA, and nine sera were not reactive. Nine of 13 HCD 3.0 positive sera were reactive by recombinant immunoblot assay(Lucky-Confirm). Also seven of these 13 sera had detectable HCV genomic RNA by reverse transcriptase-polymerase chain reaction(RT-PCR). None of nine HCD 3.0 negative samples had detectable immunoblot assay and HCV genomic RNA. It is concluded that the new HCV EIA can decrease a significant false positivity of second generation EIA in a blood donor population. This new assay correlates well with detection of HCV-RNA by RT-PCR and identifies donors who are truly infected.
