A umbilical omphalomesenteric duct polyp is the result of incomplete closure of the omphalomesenteric duct, which connects the midgut with the yolk sac of the embryo. It may be associated with underlying embryologic anomalies such as Meckels diverticulum and umbilical enteric fistula, the complications of which may at times be fatal. This rare malformation should be clinically discerned from persistent granulation tissue or pyogenic granuloma. Histologically, it shows a polypoid lesion consisting of ectopic gastrointestinal epithelium with the appearance of gastric, intestinal, or colonic mucosa. We report a case of an umbilical omphalomesenteric duct polyp in an 8-year-old male patient, who had had a bright-red polyp on the umbilicus from the age of 1 month and had not had any other types of underlying abnormalities.

Among several diagnostic tests, a Helicobacter pylori stool antigen (HpSA) test may offer a useful noninvasive method for diagnosing infection without sacrificing animals. In this study, male C57BL/6 mice (n=6) were infected with H. pylori ATCC 49503 (1x10(8) CFU/mouse) by intragastric inoculation three times at 2-day intervals, and H. pylori infected stool specimens were collected 1, 3, 5, 7, 14, 21 days after infection to assess reliability of the HpSA test. Five of six specimens were positive at 5-21 days after infection, and the sensitivity of the HpSA test was 83.33%. The presence of H. pylori infection was confirmed by the rapid urease test and genomic DNA polymerase chain reaction (PCR), and showed the same results as the HpSA. However, the rapid urease test and genomic DNA PCR are invasive tests and require animal sacrifice to detect H. pylori in gastric biopsy samples. We suggest that an HpSA test kit would be useful and effective for monitoring H. pylori in various laboratory animals, as H. pylori can be easily monitored without sacrificing animals.

A 51-year-old Korean woman presented with a non-tender, well-demarcated, reddish, edematous patch on the right anterior chest where a previous mastectomy and radiation therapy had been performed. She had been diagnosed as having infiltrating ductal carcinoma of the right breast about 1 year ago. Histopathological findings of the skin lesions were consistent with inflammatory metastatic carcinoma of the breast. Inflammatory carcinoma or carcinoma erysipeloides is a well-established entity most frequently associated with carcinoma of the breast. It is characterized by dermal lymphatic invasion by malignancy and clinically should be distinguished from erysipelas or cellulitis. We describe a case of inflammatory metastatic carcinoma derived from an infiltrating ductal carcinoma of the breast which can be clinically confused with radiation dermatitis.

Flatfoot deformity, defined as loss of medial longitudinal arch, sometimes involves symptoms such as medial arch pain or Achilles tendon tightening, etc. Whether the etiology of deformity is congenital or acquired, i.e., posterior tibial tendon dysfunction, symptoms are largely resolved with conservative treatment including medication, orthoses, and activity modification. Surgery should be considered in cases of failure of conservative treatment and clinicians can select an appropriate technique among many surgical options including calcaneal osteotomy or flexor digitorum longus tendon transfer. Principles of corrective surgery include the recovery of alignment and the preservation of joint motion.

We report a 77-year-old woman with bilateral pons infarction who presented with severe trismus, which was responsive to botulinum toxin-A injection. She was unable to open her mouth and showed anterior displacement of her temporo-mandibular (TM) joint on MRI findings. She was fed via nasogastric tube because of mouth opening limitation. There was no improvement of her mouth opening after range of motion exercise. She underwent closed reduction of the TM joints under general anesthesia but there was no significant improvement. Electromyography studies revealed continuous muscle activities on masseter and temporalis muscles during mouth opening. Botulinum toxin-A (Botox(R)) was injected into both the masseter and left temporalis muscles under ultrasonographic guidance. There was some improvement in mouth opening at post-injection 5 days. The inter-incisal distance improved gradually, and she could start oral feeding after 18 days. She could maintain an inter-incisal distance of 1.8 cm with favorable response during post-injection 4 months.

Infection with Helicobacter pylori (H. pylori) is strongly associated with duodenal and gastric ulcers. Substantial epidemiological data has revealed that high rates of H. pylori infection might be related to high rates of gastric cancer and gastric adenocarcinoma. In this study, a medicinal herbal plant, Cinnamomum cassia, was examined and screened for anti-H. pylori activity. Seventy percent ethanol was used for herbal extraction. For anti-H. pylori activity screening, inhibitory zone tests as an in vitro assay and in vivo study using a Mongolian gerbil (Meriones unguiculatus) model were performed. Also, the safety of herbal compounds was evaluated by animal study. As a result of inhibitory zone test, Cinnamomum cassia extract demonstrated strong anti-H. pylori activities. Also, as results of in vivo animal studies, Cinnamomum cassia demonstrated strong therapeutic effects against H. pylori infection according to the criteria of histological examination and rapid urease test. As results of the safety study, after 28 days treatment of the Cinnamomum cassia extract, the animals were not detected any grossly and histological changes. These results demonstrate that it can be successfully cured against H. pylori infection and protected from H. pylori-induced pathology with Cinnamomum cassia. It could be a promising native herb treatment for patients with gastric complaints including gastric ulcer caused by H. pylori.
