Pharyngoesophageal diverticulum is a well-known disease entity but is seldomly reported in Korean literature. Recently the authors experienced two cases of pharyngoesophageal diverticulum. A 46 year old female and a 51 year old female patients were admitted due to foreign body sensation in esophagus and dysphagia. Preoperative esophagography and esophagoscopy confirmed the diagnosis of pharyngoesophageal diverticulum in each patient. The authors performed one-stage pharyngoesophageal diverticulectomy and myotomy. Postoperative esophagography revealed no diverticulum or stenosis and symptoms were markedly relieved.

Purpose: This study was to evaluate usefulness of $^{99m}Tc$-MIBI scintimammography for dense breast by comparing concordance in test results between Tc-99m MIBI scintimammography and mammography whose effect was proved the most as an imaging tool depending on breast density and at the same time by examining limitation on evaluation depending on density of breast tissue. [Materials and Methods] In the period from December 2010 to July 2011, this study targeted 150 patients who took both of $^{99m}Tc$-MIBI scintimammography and mammography conducted by using breast gamma camera in this hospital. Breast density was classified to the four levels of pattern 1~4 based on the results of mammography. $^{99m}Tc$-MIBI scintimammography was conducted with the LCC, the RCC, the LMLO, and the RML one minute after intravenous injection of 99mTc-MIBI 7400 MBq (20 mCi) while analysis was made for concordance in test results of $^{99m}Tc$-MIBI scintimammography and mammography. [Results] Among the 150 patients, pattern 1 was found in 3 patients, pattern 2 in 44 patients, pattern 3 in 61 patients, and pattern 4 in 37 patients. There were 5 patients who showed the case where it was impossible to determine density of breast tissue due to foreign body inserted to breast. The concordance ratio of the results between $^{99m}Tc$-MIBI scintimammography and mammography was 95.5% for pattern 2, 95.1% for pattern 3 and 94.6% for pattern 4. This demonstrated that the concordance rate decreased according to the increase in breast density. [Conclusion] When there was limitation on evaluation of breast specific gamma imaging test results due to increased intake in breast tissue or surgical site, the concordance rate was 6.8% for pattern 2, 16.3% for pattern 3 and 18.9% for pattern 4. This demonstrated that the degree of limitation on evaluation of breast specific gamma imaging test results increased according to the increase in breast density.

Lumbar discs are one of the first parts of the musculoskeletal system to age in the human body. Lumbar disc for females start to age at twenty years of age and completely age between fifty and sixty. The number of lumbar herniated intervertebral disc patients are increasing rapidly; however, studies on protective inner wear are insufficient. This study was conducted to develop protective inner wear equipment that retains an aesthetic appreciation of the body. The methods and procedures of this study are as follows. First, foreign and domestic lumbar pads were researched and analyzed by visiting medical shops and internet shopping malls that sell lumbar pads. Second, the survey was conducted on forty patients with disc disease in hospitals located in Seoul and surrounding suburbs. The following are the study results and observations. First, the lumbar pads selling on the market had a variety of designs, textiles, and fabrics. The result of the research was to develop additional inner protective equipment for lumbar herniated intervertebral disc patients. Second, the survey results of the forty patients with disc disease were that housewives were the most vulnerable. All patients had experience purchasing lumbar pads. The prevention of pain and stress were the most selected responses for the motivation to buy lumbar pads. Most individuals said that they used lumbar pads for less than 1 year. Dissatisfaction came from fabric, activity and design. 'Being uncomfortable to wear' was the most common complaint. 'Protection and how easy the clothes were to wear' were the most selected for the necessity of developments. The Inner wear shape was the most selected in shape. Except for six respondents, all favored the lumbar protective inner wear design.

Ascertainment of accurate pharmacokinetic parameters for aminoglycoside dosing remains critical, as the serum drug concentration relates directly to both the therapeutic response and toxic effect. In the initial dosing of aminoglycosides, the volume of distribution is especially important because the dosage is calculated by multiplying the volume of distribution by the desired serum concentration. Aminoglycosides distribute into mainly the extracellular fluid and it has been reported that the volume of distribution is 0.25 L/kg. Penetration of polar aminoglycosides into adipose tissue occurs to some extent, but varies according to the degree of obesity. Therefore, dosages may be overestimated or underestimated according to the type of the dosing weight in overweight or underweight patients. Prior investigations have suggested various dosing weights which are multiplied by the popular volume of distribution to calculate the total volume of distribution. Based on other investigations, we calculated a new dosing weight which was applicable to all patients regardless of obesity in order to use the popular volume of distribution. We estimated IBW+$0.414^{\ast}$(TBW-IBW) as a new dosing weight with the SAS program. A new dosing weight is similar to those of other studies which examined in morbidly obese patients. Consequently we suggests that the dosing weight reported in morbidly obese patients can be extended to a broader patients population. But we found that the volume of distribution per kilogram from our patients was significantly larger than that for foreign patients(0.343L/kg vs 0.25 L/kg)(Kor. J. Clin. Pharm. 1999; 9(1): 15-18)

Purpose: Poisoning is a major health problem for the elderly, and poisoning can cause fatal side effects. However, the characteristics and clinical features of elderly patients with acute poisoning have not been well studied in the previous domestic research. So, we tried to analyze the clinical characteristics and toxic substances of the patients who were 65 years old or older and who were admitted to the regional emergency medical center due to acute poisoning. Methods: We retrospectively reviewed the medical records and poisoning protocols of the patients who were 65 years of age or older and who had with acute poisoning and who visited the ED in our emergency center from January 2005 to December 2009. We collected the demographic information, the gender, the underlying diseases, the causes and toxic substances, the initial presentation, the treatment and the outcomes. Results: A total of 2179 poisoned patients visited the hospital during 5 years, and among them 244 were 65 years of age or older (11.2%). The mean age was $75.6{\pm}6.9$ years and the male:female ratio was 1:1.7. The most common cause of poisoning was suicide (73.4%) and the most common source of poisonous substances was their own drugs. Of the substances used for poisoning, benzodiazepine was the most common drug (25.8%), followed by sedatives other than benzodiazepine (25.4%), insecticide (12.7%), chemical agents (12.3%) and herbicides (8.2%). The most common initial presentation was mental change (64.8%). When comparing the factors between the three elderly groups, there was no difference in gender, the cause, the substances and the underlying disease. The outcomes of treatment included ICU admission (56.1%), a good condition at discharge (12.7%) and admission to a general ward (12.7%). The overall mortality rate was 10.2% for the elderly patients. Conclusion: In this Korean study, unlike the foreign studies, the most common cause of poisoning in elderly patients was intentional poisoning. The admission rate was 68.8% and mortality rate was 10.2%.

Objective: The purpose of this review is to analyze the clinical studies on tongue diagnosis in cancer patients. Methods: Domestic and foreign databases were used, such as Pubmed, google scholar, Wanfang med online, Scopus, and OASIS. Searching keywords were tongue diagnosis, tongue color, tongue fur, tongue inspection, cancer, tumor, neoplasm, carcinoma, etc. Studies on tongue diagnosis in cancer patients were included. The published year was limited from 2000 to June 2022. Results: Thirteen studies were enrolled. All selected studies were cross-sectional studies. Cancer patients tend to have a dark and blue-purple tongue, thick fur, yellow fur, fissure tongue, and red dots on the tongue compared with non-cancer patients. With the aggravation of cancer, the rate of patients having dark or blue, or purple tongues increased, and the patients' sublingual veins became wide and tortuous. Conclusion: This study suggests that cancer patients tend to have distinct features of tongue diagnosis. Further researches are warranted.

Lung cancer is the leading cause of cancer-related mortality worldwide, and more than 80% of cases are of non-small cell lung cancer. Although chemotherapy and molecularly targeted therapy may provide some benefit, there is a need for newer therapies for the treatment of patients with advanced NSCLC. Immunotherapy aims to augment the recognition of cancer as foreign, to stimulate immune responsiveness, and to relieve the inhibition of the immune response that allows tolerance to tumor survival and growth. Two immunotherapeutic approaches showing promise in NSCLC are immune checkpoint inhibition and cancer vaccination. Although currently immunotherapy does not have an established role in the treatment of NSCLC, these patients should be enrolled in formal clinical trials.
