We studied clinicopathologic features of 44 cases of PM (proper muscle) gastric cancer, correlated the lymph node metastasis and found the result of immunohistochemical staining for tumor angiogenesis using antibodies to Factor VIII-related antigen and nm23-H1, known as meatastasis inhibitory substance. The results were as follows: 1) The average age of these 44 cases of PM gastric cancer was 55.1 years old (range 35-81). The ratio of male to female was 2.2 : 1. The tumor was located at the antrum of stomach in 72.7% of the cases. The average size of the tumor was 4.1 cm (range 0.6-9). The gross features were comprised of Borrmann type I (6.8%), II (29.6%), III (56.8%), IV (6.8%), respectively. The microscopic type was a diffuse type in 70.5% and an intestinal type in 29.5%. There were lymph node metastasis in 25 of the 44 cases (56.8%). 2) The microvessel count was higher in the lymph node positive group (average 69.3) than in the lymph node negative group (average 45.6) (P=0.004). There was a higher microvessel density in diffuse type, over 4 cm of tumor size, proximally located tumor, older than 50 years, Borrmann type II and IV, but there was no statistically significant correlation. 3) The more decreased expression of nm23-H1 was found in the lymph node positive group (56.0%) than in the lymph node negative group (31.6%), but showed no statistical significance (P=0.0142). There was no significant correlation between the expression of nm23-H1 and the other clinicopathologic factors. We suggest that the microvessel count of the tumor angiogenesis may be a prognostic factor for predicting lymph node metastasis and also help to determine the therapeutic modalities of PM gastric cancer.

Nucleolar organizer regions(NORs) are argyrophilic and have a loops of DNA that tran scribes to ribosomal RNA by RNA Polymerase I and are involved in formation of nucleolus. They are used in measuring proliferative activity of cells. Mean AgNORs count is increased or large and NORs are irregular in shape in malignant tumors. To examine the relationship of AgNORs to the survival rate of the patients with invasive colorectal adenocarcinoma, we counted mean AgNORs in 200 tumor cells and mean AgNORs#(mean AgNORs in counting AgNORs of the upper 40 nuclei after sorting AgNORs counts of 200 cell nuclei in descending order) after AgNOR staining using 45 cases of formalin-fixed, paraffin-embedded tissue surgically excised at Kang-Dong Sacred heart hospital. The survival rates were not related to age, sex, locations, differentiation, mAgNORs and mAgNORs# except Dukes'stages. There were only statistical significances in AgNORs# between high and low age group(p=0.0001), and between colon and rectum(p=0.005). But it is known that there could be different results according to staining time, fixation and preservation of tissues, counting methods in measuring AgNORs. There might be clinical usefulness of AgNOR if more cases are examined together with better tissue processing and staining methods.

PURPOSE: We attempted to identify the prostatitis in men with elevated serum prostate specific antigen (PSA) levels, and also determined whether treatment with antibiotics lowers serum PSA, resulting in decreases of the frequency of prostatic biopsies. MATERIALS AND METHODS: Men with lower urinary tract symptoms, and serum PSA greater than 4ng/ml, were evaluated for the presence of prostatitis. Prostatitis was defined as over 20 white blood cells in expressed prostatic secretions. Patients with prostatitis were treated with a 4-week course of antibiotics. Patient without signs of prostatitis underwent transrectal biopsies. PSA blood tests and prostatic massages were repeated 4 weeks later. Patients with PSA levels greater than 25ng/ml were excluded. RESULTS: Of the 49 patients with elevated PSA levels (with a mean PSA level of 9.26ng/ml), 29 (59%) had the laboratory signs of prostatitis. In 18 patients (62%) with prostatitis, the serum PSA level decreased to below 4ng/ml (mean 2.73ng/ml) after treatment. The remaining 11 patients with prostatitis, and the 20 patients without, underwent sextant transrectal ultrasound guided biopsies; which resulted in pathologic confirmation of prostate cancer in 3 out of the 11 patients with prostatitis, and in 4 (20%) out of the 20 patients without. Screening for prostatitis decreased the frequency of a prostatic biopsy by 32.7%. CONCLUSIONS: In over half of the patients with elevated serum PSA levels, the clinical evaluation revealed evidence of prostatitis. The treatment of prostatitis in this study decreased prostate biopsies by 32.7%. We suggest that screening for prostatitis in patients with elevated PSA levels, and it subsequent treatment can decrease the percentage of negative biopsies.

The report of aspiration cytologic findings of epithelial-myoepithelial carcinoma(EMC) in the salivary gland is extremely rare. We present a case of fine needle aspiration cytology(FNAC) from EMC in the right submandibular gland of a 46 years old male patient. Neck CT scan revealed a confined lesion in the submandibular gland without enlargement of the regional lymph node. FNAC from the tumor showed several three-dimensional cellular clusters with admixed normal acinar cells. They frequently formed branching tubular structures composed of two type of cells; darker cells having eosinophilic scanty cytoplasm with round dense nuclei and clear cells having abudant pale cytoplasm with vesicular nuclei at the periphery of clusters. The tumor cells of both types did not show pleomorphism or mitoses. The resected submandibular gland showed an ill-defined whitish firm tumor, measuring 2 X1.5X2cm. The histology revealed an infiltrative tumor showing characteristic two cell types in a duct-like arrangement surrounded by thin basement menbrane. An inner layer of darker cells and outer layer of clear cells were postive for cytokeratin in the former and S-100 protein in the latter on the immunohistochemical stain.

An ex vivo assay determining the flavin-containing monooxygenase (FMO) activity in perfused rat liver has been developed by assessing the rate of thiobenzamide S-oxide (TBSO) formation from the infused thiobenzamide (TB). The hepatotoxicity by TB or TBSO was not a critical factor for maintaining the FMO activity for up to 50 min. The FMO activity expressed in nmoles TBSO produced/g liver/min was the same for the recycling and non-recycling perfusion. This implies that reduction of the oxidized TBSO back to the parent compound (TB) is negligible. Hydrolysis of the collected perfusates with either beta-glucuronidase or arylsulfatase did not increase the TBSO level and thus, TBSO does not appear to undergo conjugation either to glucuronide or sulfate esters. Thus, measuring the rate of TB S-oxidation in the isolated perfused liver with 1 mM TB for 50 min provides a useful tool for evaluation of the hepatic FMO activity in the absence of hepatic necrosis and without the interferences caused by further conjugation or back reduction of the TBSO to the parent TB.

A double eyelid plasty is performed by an incision technique or a nonincision technique, the latter comprising a stitch method and a buried suture method. With this surgery, an appropriate design and operative technique must be selected into careful consideration of patient's desire and eyelid condition. Patients were classified into four groups according to age and upper eyelid condition and got double eyelid plasty, modified techniques based on the Shirakabe's bead stitch method by each group. From above mentioned techniques, authors obtained a relatively successful result, so authors would like to report the outcome of the modified surgery methods. In this study, bead stitch method was performed in 405 patients(402 females, 3 males, average 31.2 years) from January to December of 2001. The follow up period ranged from one month to four years. Preoperatively, considering the patient's age, skin laxity of the upper eyelid and quantity of periorbital fat, patients was divided into four groups. For the bead stitch method, the eyelid is everted by raising the eyelash, and No. 2 braided white silk suture 16 cm in length is thrust from the two third of upper tarsal rim on the conjunctival side to the anticipated point on the skin side by using No. 5 round needle. The other end of the suture is guided out at a 4 to 5 mm distance from that point in a similar manner, such a procedure is usually carried out six to seven times for each eye. Simultaneously, if necessary, defattimg, skin undermining and upper blepharoplasty was also performed. Most of our patients were satisfied except thirteen cases with minor complications(mild asymmetry: 7 cases, sunken eye: 3 cases and high fold: 3 cases). But, the post operative palpabral swelling is comparatively strong. In conclusion, Some of the positive aspects were the followings: Lowering the chance getting an infection from stitches, the prevention of loosening by the scars forming double eyelids, and the development of natural double eyelids coming from the even pressure on the upper eyelids by the glass beads. Moreover, the new method improves, by combining the bead stitch method with the blepharoplasty, the prior incision method, which was difficult to apply to eyelids with excessive skin, therefore being able to expect more successful results from all age groups.

Neurilemmoma of the head and neck is not rare in parapharynx, but rare in the larynx. The treatment of choice in neurilemmoma of the larynx is a complete surgical resection. A small size lesion can be removed via an endoscopic approach. For a large size lesion, an external approach, such as the median or lateral thyrotomy, or pharyngotomy, can be more useful. These surgical methods often require preliminary tracheostomy to secure the airway. Through a case of neurilemmoma of the larynx, we present this disease and the treatment course of a patient, who has been successfully treated by surgical excision via trans-cricothyroid membrane approach without tracheostomy. Furthermore, we discuss its symptoms, physical examinations, microscopic features and other options of treatment for laryngeal schwannoma through literature reviews.

The genus Mitrula (Mitrulaceae, Helotiales), as also known as swamp beacons, inhabits submerged, decaying vegetation in standing or decaying needles, twigs, leaves, and shallow water. They play an important role in carbon cycling in some freshwater ecosystems. In the herbarium of the Korea National Arboretum (KH), seven Mitrula specimens were collected during mushroom forays in the period from 2019 to 2021. The Korean collections were found to be macromorphologically closely related to M. paludosa and M. elegans, but micromorphologically they could be distinguished by characteristics of slightly narrower asci and aseptate ascospores. Our molecular phylogenetic analyses of the internal transcribed spacer (ITS) and 28S rDNA regions also revealed that our specimens were related to M. paludosa and M. elegans, but formed a distinct clade. Based on these results, we reported our specimens as new to science and discussed the phylogeny and diversity ofMitrula species.

Purpose: To report a case of type III Usher syndrome that has not been previously reported in the Republic of Korea.Case summary: A 39-year-old female visited the local eye clinic for ophthalmic evaluation and then visited our ophthalmologydepartment due to a need for further evaluation and proper management. She complained of night blindness after she becamean adult. She underwent a funduscopic examination, which revealed decolorization and atrophy of the retinal pigment epithelium,bony spicule pigmentation in the retina, and thinning of the retinal arteriole. Results of an electroretinogram and electrooculogramrevealed that responses were weak. She was diagnosed with the fourth grade of hearing impairment according to hermedical history. There was no mental retardation. According to her family history, her mother had hypermetropia, and her brotherhad astigmatism. There was no other medical history, including ophthalmic history. She was diagnosed with type III Usher syndromebased on ataxia and the dynamic visual acuity test. Conclusions It may be necessary to consider a genetic disease by assessing other systemic symptoms when a patient with retinitispigmentosa is diagnosed.

Purpose: To compare the surgical outcomes of peritoneal irrigation versus suction alone during laparoscopic appendectomy and to identify the risk factors of surgical site infection in patients with uncomplicated acute appendicitis. Methods: Data from patients with uncomplicated acute appendicitis between January 2014 and March 2016 were reviewed. We compared the irrigation and suction alone groups with regard to the following parameters: postoperative complication incidence rate, length of hospital stay, operation time, time to flatus, time to diet commencement, and duration of postoperative antibiotic. Results: A total of 578 patients underwent laparoscopic appendectomy for uncomplicated acute appendicitis. Twenty-five patients were excluded from the analysis because of need for drain insertion, loss to follow-up, simultaneous surgery for another indication, presence of an appendix tumor, or pregnancy. A total of 207 patients (37.4%) had undergone irrigation, and 346 patients (62.6%) received suction alone during laparoscopic appendectomy. The preoperative fever rate was significantly higher in the irrigation group than in the suction alone group. Operative time was also significantly longer in the irrigation group than in the suction alone group (53.8 ± 18.5 minutes vs. 57.8 ± 21.4 minutes, P = 0.027). The postoperative complication rate was higher in the irrigation group than in the suction alone group (4.5% vs. 12.6%, P = 0.001). Multiple logistic regression analysis showed that irrigation and preoperative fever were risk factors for surgical site infection after laparoscopic appendectomy for uncomplicated acute appendicitis. Conclusion There is no advantage to irrigating the peritoneal cavity over suction alone during laparoscopic appendectomy for uncomplicated acute appendicitis. Irrigation may actually prolong the operative time and therefore be detrimental.
