Oketsu-night sweat was first mentioned in the “Yi lin gai cuo” by Wang Qing ren and the “Xue zheng lun” by? Tang Rong chuan, but there are few explanations of its disease condition. Thus we made pathological studies in Oriental medicine based on three cases (women), where Oketsu-sho was alleviated with Keppu-chikuo-to modification, and Teitou-gan and Tokaku-joki-to (Tao he cheng qi tang) modification. Common disease conditions were Netsu-sho or heat syndrome (summer incidences, redness, flushing during night sweat), and lower Oketsu symptoms (lower abdominal distention, distention and cramping of the lower abdomen, and increased urinary frequency). The theory of these disease conditions is as follows: During sleep, Wei-energy enters the blood. Because of this, Wei-energy of the body surface becomes asthenia making it easier to break out in sweat. The Wei-energy in the blood is depressed by Oketsu, and heat of Oketsu becomes stronger during the night. This fever heats and evaporates bodily fluids, and as a result fluids are pushed outward and cause night sweat. Therefore heat syndrome appears to be a pre-condition of Oketsu-night sweat. If the lower aspect of the body is taken to mean the liver, one would hypothesize that Oketsu-night sweat is more likely to emerge because blood accumulates in the lower area because it returns to the liver at night. Thus, it is thought to be necessary to consider Oketsu as one of the causes of night sweat.

This paper reports the results of clinical research on spring pollen disease based upon the Oriental medical diagnoses. Sixty-nine patients (twenty-four males and forty-five females) who were afflicted with the spring pollen disease were categorized into groups according to the types of Oriental herbal medicine that they responded to. Then, the authors compared the respective periods when the disease first developed in the patients of each group. A comparison was also made based on the differences between their objective signs and subjective symptoms.
As a result of the research, the types of spring pollen disease observed have been classified into the following three groups, with one exceptional type (see Example 4). The first is a group for which “a treatment for superficies-syndrome” (Kai-hyo) was effective using “the drugs of acrid taste and warm nature” (Shin-on) (see Example 23). The patients of this type first manifested their symptoms in the period between the end of January and mid-February. It was found that most of them exhibited a predisposition to a “hypofunctioning condition” (Kyo-sho), and were diagnosed as having pollen disease with the “wind-cold symptom” (Fu-kan-sho). The second is a group for which “a treatment for superficies-syndrome” was effective using “acrid and coldnatured drugs” (Sin-ryo) (see Example 22). Most of the patients of this type first manifested their symptoms after mid-February. It was found that they exhibited the symptom of “cold in the superficies” (Gai-kan) and “the pathogenic factor blending wind-evil and heat-evil” (Fu-netsu), and that most of them manifested “a hyper-functioning condition” (Jitsu-sho). They were diagnosed as having pollen disease with the “wind-warm symptom” (Fu-on-sho) of a “warm disease” (On-byo) with a strong “wind-evil” (Fu-ja) and weak “warm-evil” (On-ja). The third is a group with the mixture of “the treatment for superficies-syndrome” with “the drugs of acrid taste and warm nature” and those of “acrid and cold nature” (see Example 20). It was found that the patients of this group carried little predisposition to “a hypofunctioning condition, ” and that they exhibited a mixed condition of coldness and heat, carrying both characteristics of the first and second groups. They were diagnosed as having the pollen disease with “auxiliary symptoms” (Ken-sho), “the wind-warm symptom” of “a warm disease” combined with “cold-evil” (Kan ja).

BACKGROUND/AIMS: Poor suction ability through a narrow working channel prolongs esophagogastroduodenoscopy (EGD). The aim of this study was to evaluate suction with a new ultrathin endoscope (EG-580NW2; Fujifilm Corp.) having a 2.4-mm working channel in clinical practice. METHODS: To evaluate in vitro suction, 200 mL water was suctioned and the suction time was measured. The clinical data of 117 patients who underwent EGD were retrospectively reviewed on the basis of recorded video, and the suction time was measured by using a stopwatch. RESULTS: In vitro, the suction time with the EG-580NW2 endoscope was significantly shorter than that with the use of an ultrathin endoscope with a 2.0-mm working channel (EG-580NW; mean +/- standard deviation, 22.7+/-1.1 seconds vs. 34.7+/-2.2 seconds; p<0.001). We analyzed the total time and the suction time for routine EGD in 117 patients (50 in the EG-580NW2 group and 67 in the EG-580NW group). In the EG-580NW2 group, the total time for EGD was significantly shorter than that in the EG-580NW group (275.3+/-42.0 seconds vs. 300.6+/-46.5 seconds, p=0.003). In the EG-580NW2 group, the suction time was significantly shorter than that in the EG-580NW group (19.2+/-7.6 seconds vs. 38.0+/-15.9 seconds, p<0.001). CONCLUSIONS: An ultrathin endoscope with a 2.4-mm working channel considerably shortens the routine EGD time by shortening the suction time, in comparison with an endoscope with a 2.0-mm working channel.

BACKGROUND/AIMS: SOX9 is a marker for stem cells in the intestine, and overexpression of SOX9 is found in gastric and colon cancer; however, the expression of SOX9 in nonampullary duodenal adenoma and adenocarcinoma has not yet been evaluated. This study aimed to investigate SOX9 expression in nonampullary duodenal adenoma and adenocarcinoma by immunohistochemistry. METHODS: We evaluated SOX9 expression in 43 clinical samples (nonampullary duodenal adenoma in 22 lesions and nonampullary duodenal adenocarcinoma in 21 lesions) resected under endoscopic mucosal resection or endoscopic submucosal dissection. RESULTS: SOX9 was expressed in part of the base of the normal duodenal mucosa surrounding adenomas and adenocarcinomas. In contrast, SOX9-positive cells were found in more than half of the crypts from the bottom part of the crypt in all of the 43 samples. Moreover, in 15 adenoma samples (68.2%) and 19 carcinoma samples (90.5%), SOX9 was expressed in more than three-quarters of the crypts from the bottom part of the crypt. CONCLUSIONS: SOX9 is overexpressed in nonampullary duodenal adenoma and adenocarcinoma in humans.

Early detection and resection of neoplastic lesions are key objectives to diminish colorectal cancer mortality. Resection of superficial colorectal neoplasms, cold snare polypectomy, endoscopic mucosal resection, and endoscopic submucosal dissection have all been developed and used worldwide. The pocket-creation method facilitates the resection of tumors in difficult and routine locations. Early detection is the most important first step to maximize the benefits of recent advancements in endoscopic techniques. However, the detection of small, flat-shaped, or faded color lesions remains difficult. Linked color imaging, a novel multi-light technology, facilitates the recognition of minor differences in tissue by enhancing the color contrast between early colorectal neoplasms and surrounding normal mucosa in a bright field of view. The most striking feature of linked color imaging is its ability to display the color of early neoplastic lesions as distinct from inflammatory changes, both of which have similar “redness” when viewed using white light imaging. To increase the detection rate of neoplasms, linked color imaging should be used from the outset for endoscopic observation. Early detection of superficial colorectal tumors can result in decreased mortality from colorectal cancer and maintain a good quality of life for patients.

A 62-year-old man with a flat early esophageal cancer was referred for endoscopic treatment. White light imaging revealed a pale red lesion, whereas linked color imaging (LCI) and blue laser imaging (BLI) yielded purple and brown images, respectively. Iodine staining demonstrated a large unstained area with a homogenous but very weak pink-color sign. This area appeared more clearly as purple and green on LCI and BLI, respectively; however, a different colored portion was observed at the 4 o'clock position inside the iodine-unstained area. Histopathology findings of the resected specimen revealed squamous intraepithelial neoplasia at the 4 o'clock position and an esophageal squamous cell carcinoma in the remaining iodine-unstained area. LCI and BLI combined with iodine staining produce characteristic images that overcomes the pink-color sign, reflecting the histological features of a flat esophageal neoplasm. This new method is useful for detailed evaluation of early flat squamous cell neoplasms.

White light imaging (WLI) may not reveal early upper gastrointestinal cancers. Linked color imaging (LCI) produces bright images in the distant view and is performed for the same screening indications as WLI. LCI and blue laser imaging (BLI) provide excellent visibility of gastric cancers in high color contrast with respect to the surrounding tissue. The characteristic purple and green color of metaplasias on LCI and BLI, respectively, serve to increase the contrast while visualizing gastric cancers regardless of a history of Helicobacter pylori eradication. LCI facilitates color-based recognition of early gastric cancers of all morphological types, including flat lesions or those in an H. pylori-negative normal background mucosa as well as the diagnosis of inflamed mucosae including erosions. LCI reveals changes in mucosal color before the appearance of morphological changes in various gastric lesions. BLI is superior to LCI in the detection of early esophageal cancers and abnormal findings of microstructure and microvasculature in close-up views of upper gastrointestinal cancers. Excellent images can also be obtained with transnasal endoscopy. Using a combination of these modalities allows one to obtain images useful for establishing a diagnosis. It is important to observe esophageal cancers (brown) using BLI and gastric cancers (orange) surrounded by intestinal metaplasia (purple) and duodenal cancers (orange) by LCI.

Barrett's adenocarcinoma may occur in multiple sites, and recurrence and metachronous lesions are the major problems with endoscopic resection. Therefore, early detection of such lesions is ideal to achieve complete resection and obtain improved survival rates with minimally invasive treatment. Laser imaging systems allow multiple modalities of endoscopic imaging by using white light laser, flexible spectral imaging color enhancement (FICE), blue laser imaging (BLI), and linked color imaging even at a distant view. However, the usefulness of these modalities has not been sufficiently reported regarding Barrett's adenocarcinoma. Here, we report on a patient with three synchronous lesions followed by one metachronous lesion in a long segment with changes of Barrett's esophagus, all diagnosed with this new laser endoscopic imaging system and enhanced by using FICE and/or BLI with high contrast compared with the surrounding mucosa. Laser endoscopic imaging may facilitate the detection of malignancies in patients with early Barrett's adenocarcinoma.
