Congenital absence of the major salivary glands, especially of the parotid gland, is a rare disorder whose etiopathogenesis is poorly understood. Aplasia of the parotid glands may be unilateral or bilateral and may occur alone or in association with the absence of other salivary glands or with other developmental anomalies of the first branchial arch, such as hypoplasia or aplasia of the lacrimal glands, hemifacial microsomia, mandibulofacial dysostoses, and multiple congenital anomalies. Various degree of xerostomia and dental caries with early loss of teeth may occur due to decreased salivary production. The authors experienced a case of unilateral parotid aplasia in a 22-year old female who had painless swelling in the right parotid region. We present this case with review of literature.

Gastrocelic fistula of malignant origin is a rare complication, usually due to gastric or colon cancer. Possible other etiologic factors resulting in gastrocolic fistula are peptic ulcer, trauma, carcinoid tumor, intestinal tuberculosis, Crohn's disease, lymphoma, intraabdominal abscess, diverticulitis and etc. At the present, earlier diagnosis and treatment of gastric and colon cancer may explain the low frequency of malignant gastrocolic fistula than the past but the review of Korean literatures revealed only two reports of gastrocolic fistula secondary to gastric cancer and another from benign gastric ulcer. Yet, there has been no report of fistula due to colon cancer. We experienced a case of colon cancer with postural dizziness, fecal eructation who was diagnosed as gastrocolic fistula by endoscopy, barium enema, UGI series and finally underwent operation. Therefore, we report this case with the review of literatures.

BACKGROUND: Infectious vaginitis is a common gynecologic disease that is primarily caused by three pathogens (Trichomonas vaginalis, Gardnerella vaginalis, and Candida species). The aim of this study was to confirm the effects of other infectious vaginitis-related test results on the interpretation of Gram stain and Papanicolaou (Pap) smear test results for disease diagnosis. METHODS: A total of 300 vaginal samples were collected from women presenting symptoms of vaginitis. The presence of the three previously mentioned pathogens was evaluated using both a Gram stain and Pap smear test, and interpreted twice by 4 different observers. The first interpretation was performed without any information, and a second interpretation was performed with knowledge of results of an Affirm VPIII test that was used to diagnose infectious vaginitis. The results from the two interpretations were compared and the sensitivity and specificity of both tests were evaluated. RESULTS: For the Gram stain samples, the detection rates of G. vaginalis were increased in the second interpretation by 6.2%, while the detection rates of Candida spp. were decreased by 0.3%. For the Pap smear test samples, the detection rates of G. vaginalis were increased in the second interpretation by 7.0%, and the detection rates of Candida spp. were increased by 2.0%. The sensitivity of both tests was increased in the second interpretation by 5.5% to 66.7%. There was no difference in the specificity between the two interpretations. CONCLUSIONS: We demonstrated that there is significant inter-observer variation when using Gram stain and Pap smear test results to diagnose infectious vaginitis. The detection rates and sensitivity of both tests changed when the results from an additional test were incorporated into the interpretation. Additional studies are needed to develop objective criteria and a standardized interpretation system for the evaluation of results from these diagnostic tests.

We studied the incidence and results of treatment of secondary hypertension in Yeungnam University Hospital. Nineteen hundred fifty patients with hypertension were included from march 1990 to march 1994. We analysed the prevalence of secondary hypertension and results of treatment. The incidence of secondary hypertension in Yeungnam University Hospital was six percent. The most common underlying causes of secondary hypertension was renal parenchymal disease. Patients with three forms of potentially reversible secondary hypertension, namely, renovascular hypertension, endocrine disease, exogenous hormone, were assed to determine whether surgery or withdrawal of the exogenous hormane had led to an improvement in blood pressure control. The incidence of secondary hypertension in Yeungnam University Hospital was low(6%), but some of these are curable. Thus it is very inportant that evaluate the secondary hypertension.

Gastrocolic fistula is a rare lesion which is caused most commonly by carcinoma of colon or stomach. The less common causes of gastrocolic fistula are follows: trauma, faulty gastrocolic anastomosis during gastrectomy, benign gastric ulcer, syphilis, carcinoid tumor, tuberculosis, intraperitoneal abscess, lymphoma, perforated diverticulum of colon, and ulcerative colitis. The locations of fistulae are mostly between greater curvature of stomach and distal half of the transverse colon. In the case of penetrating benign gastric ulcer and gastrcolic fistula, it is usually associated either with asipirin or with prolonged steroid administration. A 36-year-old male who had an unusual gastrocolic fistula secondary to non-surgically treated benign gastric ulcer is presented. The exitence of a gastrocolic fistula was dernonstrated by radiological examination of the colon and the stomach. In this patient, the colonoscope passde through the fistula and the stomach could be examined. Careful preparation was carried out preoperatively with intravenous fluids and blood transfusions. Resection of the distal stomch, fistulous tract, and segment of the transverse colon was then accamplished.

BACKGROUND AND OBJECTIVES: With the currently available diagnostic procedure, hearing impaired children are diagnosed at an early age and hearing aids are fitted soon thereafter. Thus, appropriateness of using available correction methods for adult ears and ear models for determining and predicting hearing aid characteristics for these children need to be examined. The objectives of this study are to create a database of resonance frequency and length of external auditory canal (EAC) in all age groups and to adjust the peak frequency response of hearing aid system to take account of the changing resonance peak frequency as child gets older. MATERIALS AND METHOD: We studied 437 ears with no age limitation. We measured rear ear unaided response (REUR) with Rastronics frequency response analyzer and external ear canal length using silastic tube under microscopic or otoscopic finding. Statistical analyses were performed to determine age differences. RESULTS: Ear canal length increased with age, and an adult value was achieved by the age of 14 years. Resonance frequency decreased with age, and reached to an adult value by the age of 9 years. There was significant relationship between ear canal length and resonance frequency. CONCLUSION: Alteration in resonance frequency with age may have practical implications by affecting the insertion gain of hearing aid system in children. The data may be used as useful adjustment factors to correct the current hearing aid system in children.

Purpose:
This study examined the utility of preliminary magnetic resonance imaging (MRI) measurements in the ultrasound-guided L4 selective nerve root block.
Materials and Methods:
As a retrospective study, 71 patients, who met the criteria for outpatient visits from March 2016 to December 2017, were included. From March 2016 to February 2017, 31 patients who underwent an L4 nerve root block without MRI were classified as group A, and 40 patients who underwent an L4 nerve root block through MRI measurements from March 2017 to December 2017 were classified as group B. Group A was injected under ultrasound-guidance through the pararadicular approach without a pre-interventional MRI evaluation, and group B was injected under ultrasound-guidance according to the preliminary MRI measurements. The results were assessed using the numeric rating scale scores before, three hours, and two, six, and 12 weeks after the procedure.
Results:
At three hours after the procedure, the proportion of patients better than good results were 51.6% in group A and 67.5% in group B. At two weeks after the procedure, the proportion of patients with better than good results were 48.4% and 70.0% in groups A and B, respectively; 58.1% and 62.5% of patient of groups A and B, respectively, showed better than good results after six weeks. In 12 weeks after the procedure, the results of group A and B were 67.7% and 62.5%, respectively. At three hours and two weeks after the procedure, group B showed significant symptom improvement than group A (p<0.05). The procedures were repeated 2.8 and 1.7 times in groups A and B, respectively, between two and six weeks for satisfactory pain relief (p<0.05).
Conclusion
A pre-interventional MRI evaluation might improve pain relief within the initial two weeks after ultrasound-guided L4 selective nerve root block by improving the success rate of the procedure.

During 2011~2013, a total of 729 samples for 19 types of medicinal plant were collected from Seoulyekryungsi in Seoul, Korea, and investigated for the presence of aflatoxins. The samples were analyzed using immunoaffinity column cleanup and high-performance liquid chromatography coupled to a fluorescence detector after post-column derivatization. Aflatoxins were found in 124 out of the 729 analyzed samples: 65 containing aflatoxin B1 (AFB1), 24 with aflatoxin B2 (AFB2), 15 with aflatoxin G1 (AFG1), and 20 samples with aflatoxin G2 (AFG2). The ranges for positive samples were 0.1~404.7 microg/kg for AFB1, 0.1~10.0 microg/kg for AFB2, 0.1~635.3 microg/kg for AFG1, 0.1~182.5 microg/kg for AFG2, and 0.1~1,043.9 microg/kg for total aflatoxins. Most of the medicinal plant samples (721, 98.9%) were below legal limits, but 8 samples exceeded the legal limits of 10 and 15 microg/kg established by the Korean standard for AFB1 and total aflatoxins (the sum of AFB1, AFB2, AFG1 and AFG2), respectively.

Cytomegalovirus(CMV) infections are common in immune compromised situations such as human immunodeficiency virus infection and organ transplantation. However CMV colitis had been rarely found in immunocompetent individuals. We experienced a case of an 83-year-old female patient, initially immune competent, who developed a massive lower gastrointestinal bleeding caused by CMV colitis. Previously, multiple antibiotics were used for nontuberculous Myco- bacterium and other bacterial infections after total knee arthroplasty. Colonoscopy revealed multiple ulcerations and mucosal congestion with hemorrhage. In spite of ganciclovir therapy, our patient did not recover.
