We report a case of hepatocellular carcinoma presented with severe hypoglycemia. Computerized tomography and ultrasonography revealed a massive bilateral tumor with portal vein thrombosis. The levels of IGF-I (113 ng/mL) and IGFBP- (815 ng/mL) measured in the plasma, were lower than normal range. There was strong immunoreactivity of IGF- and IGF-I in immunohistochemical stain of tumor cells.

Cyclooxygenase-2 (COX-2) is an enzyme induced by various proinflammatory and mitogenic stimuli. Celecoxib is a selective inhibitor of COX-2 that have been shown to affect cell growth and apoptosis. Lung cancer cells expressing COX-2 is able to be a target of celecoxib, this study focuses on investigating that celecoxib induces apoptosis via endoplasmic reticulum (ER) stress on lung cancer cells. We investigated whether celecoxib induced apoptosis on non-small cell lung cancer cell line, A549 and H460. The 50 µM of celecoxib increased apoptotic cells and 100 µM of celecoxib significantly induced apoptosis. To check involvement of caspase cascade, pretreatment of z-VAD-fmk blocked celecoxib-induced apoptosis. However, caspase-3, -8, and -9 were not activated, but cleavage of non-classical caspase-4 was detected using western blot. As checking ER stress associated molecules, celecoxib did not increase expressions of growth arrest and DNA damage inducible protein 34, activating transcription factor 4, and spliced X-box binding protiens-1, but increase of both glucose-regulated protein 78 (GRP78) and C/EBP homologous transcription factor were detected. Salubrinal, inhibitor of eIF2 and siRNA for IRE1 did not alter celecoxib-induced apoptosis. Instead, celecoxib-induced apoptosis might be deeply associated with ER stress depending on GRP78 because siRNA for GRP78 enhanced apoptosis. Taken together, celecoxib triggered ER stress on lung cancer cells and celecoxib-induced apoptosis might be involved in both non-classical caspase-4 and GRP78.

Tumorlet is a rare lesion of disputed origin that was first described by whitwell in 1955, and about one-third of the reported cases have been associated with underlying lung disease. Patient was a 60-year-old female who was admitted with a histroy of chest discomfort and dyspnea. Right lower lobe was partially resected under the clinical diagnosis of the bronchogenic cyst. Grossly, lung tissue around round cystic lesion appeared brown firm and somewhat fibrotic, and showed several scattered ill-defined whitish gray nodules. Microscopically, lung tissue around bronchogenic cyst was partially obliterated by dense fibrous scar tissue. Within this areas of fibrosis, and in the wall of alveolar ducts and respiratory bronchioles, innumerable microscopic tumorlets were found and argyrophilic granules were also demonstrated in scattered tumorlets with Grimelius stain.

Purpose:
To report the availability of optical coherence tomography angiography (OCTA) when diagnosing type 1 and type 2 choroidal neovascularization (CNV) associated with age-related macular degeneration.
Methods:
We conducted a retrospective chart review of 63 eyes of 59 patients who visited the outpatient clinic from April 2018 to January 2020 with treatment-naïve type 1/2 CNV associated with age-related macular degeneration. The CNV was diagnosed through fluorescein angiography and indocyanine green angiography on the appearance of hyperfluorescence and leakage at the late phase. The CNV type was classified by location using OCT. These results were compared with those of automatic and manual segmentations via OCTA.
Results:
Of the 63 eyes, 45 eyes showed type 1 CNV and 18 eyes indicated type 2 CNV. Using the automatic segmented display of OCTA, type 1 CNV was identified in 29 of 45 eyes and type 2 CNV was confirmed in 17 of 18 eyes. In addition, when manual segmentation was performed, type 1 CNV was found in 41 of 45 eyes and type 2 CNV in 18 of 18 eyes. The sensitivity of diagnosis of type 1 CNV using only automatic segmentation in OCTA was 64.44%; the sensitivity increased to 91.11% when additional manual segmentation was performed (p < 0.001). For type 2 CNV, the sensitivity was 94.44% using automatic segmentation in OCTA and 100% with additional manual segmentation (p = 1.000).
Conclusions
Automatic segmentation of OCTA and OCT analyses enabled diagnosis of type 1 and type 2 CNV associated with age-related macular degeneration. The diagnosis accuracy or type 1 CNV improved significantly when manual segmentation was added.

PURPOSE: This study was to confirm the effect of acupressure on the emesis control and the weight change among pediatric cancer patients receiving anti-cancer chemotherapy. METHOD: Forty pediatric cancer patients, receiving the induction stage of chemotherapy with MTX and vincristine, were divided into control(n=20) and the intervention group(n=20). Both groups received regular anti-emesis medication, but the intervention group was added acupressure maneuver for 5 minutes on P6 point for 3 times a day for 5days: before chemotherapy, lunch and dinner by investigator during the hospitalization and by mother at home. The instruments for this study were Rhode's(1986) Index of nausea, vomiting and retching(INVR), Cas electric scale and pamphlet developed by researcher. RESULT: Significant differences in the degree of nausea and vomiting were observed between the control and the intervention group as measured by INVR(t=4.73; p=.01). Repeated measures ANOVA also shows that the group effect was significant(F=22.39, P=.01) as was the time effect(F=380.35, P=.01). The group by time interaction was also significant(F=5.27, P=.01). Acupressure maneuver was apparently effective in reducing the degree of chemotherapy-induced nausea and vomiting. There were also statistically significant weight loss noted in the control group than the intervention group(t=5.42, p=.01). CONCLUSION: Acupressure on P6 point shows an effective adjunct maneuver in reducing the degree of nausea and vomiting and conserving the weight in pediatric cancer patients. Therefore, it is proposed that acupressure should be applied as supportive nursing intervention strategies to relieve chemotherapy induced nausea and vomiting and to prevent weight loss in pediatric cancer patients.
