Background: Snoring is the cardinal symptom of obstructive sleep apnea (OSA). Snoring and upper airway obstruction associated with major oxygen desaturation may occur in populations undergoing flexible bronchoscopy. Methods: To evaluate the prevalence of patients at a high risk of having OSA among patients undergoing bronchoscopy with sedation and to investigate whether snoring during the procedure predicts patients who are at risk of OSA, we prospectively enrolled 517 consecutive patients who underwent the procedure with moderate sedation. Patients exhibiting audible snoring for any duration during the procedure were considered snorers. The STOP-Bang (Snoring, Tiredness, Observed apnea, high blood Pressure-Body mass index, Age, Neck circumference and Gender) questionnaire was used to identify patients at high (score ${\geq}3$ out of 8) or low risk (score <3) of OSA. Results: Of the 517 patients, 165 (31.9%) snored during bronchoscopy under sedation. The prevalence of a STOP-Bang score ${\geq}3$ was 61.9% (320/517), whereas 200 of the 352 nonsnorers (56.8%) and 120 of the 165 snorers (72.7%) had a STOP-Bang score ${\geq}3$ (p=0.001). In multivariable analysis, snoring during bronchoscopy was significantly associated with a STOP-Bang score ${\geq}3$ after adjustment for the presence of diabetes mellitus, chronic obstructive pulmonary disease, chronic kidney disease, and stroke (adjusted odds ratio, 1.91; 95% confidence interval, 1.26-2.89; p=0.002). Conclusion: Two-thirds of patients undergoing bronchoscopy with moderate sedation were at risk of OSA based on the screening questionnaire. Snoring during bronchoscopy was highly predictive of patients at high risk of OSA.

Objectives: Pre-pregnancy diet has an important role in preparing for healthy generation. However, evidence on this issue has been scarce. A scoping review synthesising current evidence will support the demand to map 'what has been researched' on pre-pregnancy diet and maternal and child health. Methods: Systematic search was performed using PICOS (Population, Intervention, Comparison, Outcomes, and Study design) framework in electronic databases. Articles were screened for eligibility, summarized, and the quality was assessed using the National Institute of Health assessment tool. The review structure complies with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guide. Results: Forty-two articles were included after full-text screening. Twenty-five studies were in high-income countries (HICs), six in each upper-middle income, five in lower-middle income countries (LMICs), and one in low-income countries (LIC). Based on the regions: North America (n=16), Europe (n=5), South America (n=4), Australia (n=4), Asia (n=5), Middle East (n=2), and sub-Saharan Africa (n=1). The two-most observed diet-related exposures were dietary pattern (n=17) and dietary quality (n=12). The most assessed outcome was gestational diabetes mellitus (n=28) and fetal and newborn anthropometry (n=7). The average quality score±standard deviation was 70±18%. Conclusions: Research related to pre-pregnancy diet is still concentrated in HICs. The context of diet may vary; therefore, future research is encouraged in LMICs and LICs context, and Mediterranean, South-East Asia, Pacific, and African regions. Some maternal and child nutrition-related morbidity, such as anemia and micronutrient deficiencies, have not been discussed. Research on these aspects will benefit to fill in the gaps related to pre-pregnancy diet and maternal and child health.

Background: Total elbow arthroplasty (TEA) is uncommon, but growing in incidence. Traditionally an inpatient operation, a growing number are performed outpatient, consistent with general trends in orthopedic surgery. The aim of this study was to compare TEA outcomes between inpatient and outpatient surgical settings. Secondarily, we sought to identify patient characteristics that predict the operative setting. Methods: Patient data were collected from the American College of Surgeons National Quality Improvement Program. Preoperative variables, including patient demographics and comorbidities, were recorded, and baseline differences were assessed via multivariate regression to predict operative setting. Multivariate regression was also used to compare postoperative complications within 30 days. Results: A total of 468 patients, 303 inpatient and 165 outpatient procedures, were identified for inclusion. Hypoalbuminemia (odds ratio [OR], 2.5; P=0.029), history of chronic obstructive pulmonary disorder or pneumonia (OR, 2.4; P=0.029), and diabetes mellitus (OR, 2.5; P=0.001) were significantly associated with inpatient TEA, as were greater odds of any complication (OR, 4.1; P<0.001) or adverse discharge (OR, 4.5; P<0.001) and decreased odds of reoperation (OR, 0.4; P=0.037). Conclusions: Patients undergoing inpatient TEA are generally more comorbid, and inpatient surgery is associated with greater odds of complications and adverse discharge. However, we found higher rates of reoperation in outpatient TEA. Our findings suggest outpatient TEA is safe, although patients with a higher comorbidity burden may require inpatient surgery. Level of evidence: III.

연구배경 : 폐 국균종은 우리나라에서 비교적 흔히 볼 수 있는 만성적인 진균감염으로서 방사선학적으로는 air-crescent를 특징으로 하는 질환이다. 객혈이 주요 증상이고, 주된 선행질환으로 폐결핵이 알려져 있다. 진단은 방사선학적으로 공동내 고형 및 원형의 종괴가 공동의 벽과 분리되어 존재하는 것이며 혈청학적 검사가 진단에 도움이 된다. 치료에서는 항진균제를 포함한 보존적 치료와 수술이 있는데, 최근에는 환자의 전신상태가 양호한 경우 수술이 선호되는 경향을 보인다. 저자들은 국균종이 의심되는 환자 중 수술로서 확진이 되거나 국균항체 양성으로 판정된 환자의 임상 양상에 대하여 알아보고자 하였다. 대상 및 방법 : 1995년 1월부터 2000년 12월까지 문진과 진찰소견, 단순 흉부 방사선 검사와 전산화단층촬영에서 국균종이 의심되는 58례 중 수술을 하여 확진된 경우 9례, 기관지 내시경 및 경피적 침 생검과 국균종에 대한 항제 양성을 보이는 13례를 대상으로 후향적 분석을 하였다. 결 과 : 1) 기저질환으로는 폐결핵이 16례 (72.7%)였으며, 이중 현재 결핵균 동정에서 비결핵항산균이 3례가 있었다. 완치판정을 받은 결핵환자에서 국균종을 진단할 때까지 기간은 $5.91{\pm}5.72$년이었다. 기타로 폐농양 2례 (9.1%), 기관지확장증 1례 (4.5%), 폐기종 1례 (4.5%), 폐내 기저질환이 없는 경우 2례 (9.1%)였다. 호흡기계이외의 질환으로는 빈번한 음주력(22.7 %)과 당뇨(13.6%)였다. 2) 주소로는 객혈이 16례(72.7%)로 가장 많았으며, 진찰소견은 호흡음에서 이상을 발견할 수 없는 경우가 가장 많았다. 검사실 소견에서는 적혈구 침강속도의 증가 외에 특이사항을 발견할 수 없었다. 방사선 소견은 전산화단층촬영이 도움이 되었으며 주된 소견으로는 "fungal ball"과 "air-meniscus sign"이었다. 호발부위는 폐 상엽, 특히 후분절이 가장 많은 빈도를 보였다. 3) 기관지 동맥 색전술의 효과를 확인 할 수 없었으며, 수술방법은 엽절제술 (lobectomy)이 가장 많았고 수술 및 수술의 경과 중 특기할 만한 합병증이나 사망은 없었다. 추적접사에서 사망률은 13.6%였으나 국균종에 의한 것은 아니였다. 결 론 : 국균종은 결핵 및 기타 공동을 형성하는 질환에서 호발하는 질환이며 다량의 객혈이나 빈번한 객혈이 문제가 될 수 있다. 전신상태가 양호한 환자에서 수술이 추후에 발생하는 객혈을 비롯한 합병증 예방에 최선의 치료이지만, 전신상태가 불량하고 폐기능의 장애가 있는 환자에 대한 합병증 예방 및 근치적 치료에 여러 방법이 대두되는 바 좀더 적극적인 접근이 요구된다 하겠다.

목적: 이번 연구는 상·하악 제1대구치 부위에 식립 된 단일 임플란트를 통해 임플란트-지대주 연결 유형이 임플란트의 변연골 소실 (MBL)에 영향을 주는지, 그리고 MBL에 영향을 끼치는 요인들을 알아보기 위해 분석하였다. 연구 재료 및 방법: 5년 이상의 추적 기간 동안, 상·하악 제1대구치 부위에 단일 임플란트를 식립하여 수복한 68명의 환자(남: 38명, 여: 30명)의 87 임플란트(external connection type (EC) 임플란트: 57개, internal connection type (IC) 임플란트: 30개)를 대상으로 추적 조사하였다. 최대 5년 후의 구내 방사선 영상에서 MBL과 보철물의 출현 각도(EA)를 측정하였다. 60 - 79세에 해당하는 환자의 비율이 52.9%로 가장 높았고 상악 구치부에 임플란트가 가장 많이 식립되었다. 결과: GBR을 하지 않은 경우 EC (-0.065 ± 0.859 mm)와 IC (-0.627 ± 0.639 mm)에서 유의한 차이가 있었고, 또한 당뇨병이 없는 환자들 사이에서 EC (-0.131 ± 1.002 mm)와 IC (-0.792 ± 0.762 mm)에서 유의한 차이가 존재하였다. 임플란트 매식체의 직경, 길이, 보철물 연결 방법, 임플란트 제조업체, 보철물의 emergence angle (EA)로 구분하였을 때 각군 간에 유의미한 차이가 없었다. 다중회귀분석을 이용하여 MBL에 영향을 주는 요인분석 결과 회귀계수의 유의성 검증에서 임플란트-지대주 체결 방식(β = -0.303), 당뇨병의 유무(β = -0.113), EA의 차이(β = -0.234), 나이(β = -0.776)에서 MBL에 통계학적으로 유의한 음의 상관관계를 보였다. 결론: IC가 EC보다 GBR을 하지 않은 경우와 당뇨병이 없는 환자들 사이에서 MBL이 작다는 것을 알 수 있었다. 또한 보철물의 EA가 30°보다 큰 보철물의 형태를 가진 임플란트가 30°보다 작은 보철물의 형태를 가진 임플란트 보다 MBL이 컸으며 나이가 많을수록 MBL이 크다는 것을 알 수 있었다. 임플란트의 MBL을 최소화하고 임플란트 안정성을 확보하기 위해서 임플란트 보철물의 EA와 임플란트-지대주 연결 유형을 세심하게 고려해야 할 것이다.

Background: Although quantitative sensory test (QST) is being used with increasing frequency for measuring sensory thresholds in clinical practice and epidemiologic studies, there has been no age-matched normative data in Korean adults. The objective of this study is to evaluate the value of QST in diabetic polyneuropathy with normal range in Korean adults. Methods: The Computer Aided Sensory Examination IV 4,2 (WR Medical Electronics Co., Stillwater, Minnesota, U.S.A.), with 4,2,1 stepping algorithm was used to determine vibration and cold perception threshold in 70 normal controls and 19 patients with diabetic polyneuropathy aged from 21 to 79 years. The data were used to define age-matched upper and lower normal limits and normal range of side to side difference. We also evaluated the duration of diabetes, serum HbA1C level, and findings of nerve conduction study (NCS) and QST in patients with diabetic polyneuropathy. Results: In normal adults, sensory thresholds slightly increased with age, and a slight side-to-side difference was observed. The diagnostic sensitivity of QST was not higher than NCS in patients with diabetic polyneuropathy (36.8% vs. 42.1%, p=0.716), especially among elderly patients. Conclusions: QST might be used as a complementary test for NCS in the diagnosis of diabetic polyneuropathy. Although the QST is a simple method for the evaluation of peripheral nerve function, there are some limitations. Most of all, because the QST measuring is dependent on the subjective response of patients, the degree of concentration and cooperation of the patients can significantly affect the result. And thus, attention should be paid during the interpretation of QST results in patients with peripheral neuropathy.

Objects:It has been reported that the incidence of tardive dyskinesia(TD), the remarkable abnormal involuntary movement, was higher in the schizophrenics with high blood sugar levels and that TD had been improved by small amount of insulin-injection for 90 days. And also it was generally known that the blood lipids were higher in the schizophrenics with tardive dyskinesia. Thus, we tried to replicate the correlations of abnormal involuntary movements with blood sugar levels and blood lipids in chronic schizophrenics treated with antipsychotics. Methods:Thirty-eight male schizophrenic inpatients who were stable in clinical state with medications, were included. The patients who had been already diagnosed as diabetes mellitus(DM), organic brain disorder, substance- related disorder, physical illness were excluded and also we excluded female patients to remove the hormonal effect on TD. Eleven patients who ranked higher(above five) in the Abnormal Involuntary Movement Scale(AIMS) were assigned into 2 groups, a dibenese group and a placebo group. Diabinese or placebos were administrated for 3 weeks with antipsychotics and AIMS was rechecked. Results:There were no correlations between the total AIMS scores and blood sugar and lipids levels in all subjects. The means of total and subscale scores(objective, face, and extremity) of AIMS did not reveal statistical significances between diabinese and placebo groups. However(total, jaw, face, upper arm, and objective feeling), were statistically higher in the diabinese group than those in the placebo group. And correlations of total cholesterol(TC) with fast blood sugar(FBS), weight with body mass index(BMI) and waist, total glycerol (TG) with BMI were statistically significant. Conclusion:In this study, there were statistical significances in the changes in ratings of AIMS scores between the diabinese group and the placebo group. Application of oral hypoglycemic agent might be a way of improving abnormal involuntary movements in schizophrenics with abnormal involuntary movements or TD. Althogugh it was not certain that there were correlations of abnormal involuntary movement with blood sugar and lipids, correlations of TC/TG with AIMS, of FBS with AIMS cautiously suggest that the regular check of $HbA_1C$, waist, and weight are recommended for schizophrenics.

The microsurgical reconstruction is necessary for elderly patients to treat severe trauma and head and neck tumor. The aim of this study is to analyze the risks of microvascular surgery and whether or not happening of more complication in elderly patients who are older than 60 years old and to suggest the solution of the complication. The retrospective study included 41 elderly patients who underwent treatment of 44 microsurgical reconstructions among total 271 cases of microsurgical reconstruction from July, 1988 to December, 1998. Their ages ranged from 61 years to 79 years. There were 26 males and 15 females. The involved sites were 23 head and necks, 13 upper gastrointestinal tracts, 3 lower extremities, 1 chest and 1 sacral region. The causes of microsurgical reconstruction were 36 head and neck tumors, 2 radionecrosis, 2 traumas and 1 melanoma in lower limb. The used flaps were 14 radial forearm flaps, 13 jejunal flaps, 10 latissimus dorsi muscle flaps, 3 rectus abdominis muscle flaps, 2 lateral arm flaps, 1 scapular flap, and 1 iliac osteocutaneous flap. They had medical problems which were 29 tobacco abuse, 14 hypertensions, 13 alcohol abuse, 10 chronic obstructive pulmonary diseases, 7 diabetes mellituses, 3 ischemic heart diseases. All patients have had successful results without specific complications except 3 cases of free flap failure and 3 perioperative death. The causes of 3 flap failures were 2 flap necrosis due to arterial insufficiency and 1 flap loss due to secondary infection. All of these cases were treated with secondary free flap surgery. However 3 patients died perioperatively due to 2 respiratory arrests and 1 sepsis. It was not related to operate microsurgical reconstruction itself, but was correlated with the complication of postoperative care after head and neck surgery. We conclude that plastic surgeons consider the importance of prevention of expected complication as thorough analysis of operative risk factor and appropriate treatment. We had to select the donor and recipient vessel appropriately to perform successful microsurgery in elderly patients and consider vein graft and end-to-side anastomosis to reduce complication if necessary. In addition, we emphasize the importance of pre, peri and postoperative care in head and neck cancer patients to reduce postoperative complication and morbidity.

In order to investigate experimented effects of Indongdeung Jigolpi-Tang, which is applied to Soyangin, to diabetes, the measurement, comparison and observation made on the contents of volumes of blood glucose, total cholesterol, triglyceride, phospholipid, total protein and electrolyte($K^+$, $Na^+$) in blood serum by giving a high blood glucose, induced by streptozotocin, to hyperglycemic rats, dosing the cooked liquid of I.J.T., and following conclusion was attained. 1. The volume of glucose urine, induced by streptozotocin to hyperglycemic rats, was shown an increase in comparision to a normal flock when $12.50m{\ell}/kg$ of I.J.T. dosed to the rats and checked after two and four weeks and thereby, a sinificant reduction in the volume of blood glucose was made. 2. The volume of total cholesterol of blood serum in the diabetic rats, induced by streptozotocin, was increased in comparision to the normal flock, and in the fouth week of dosing $1.25m{\ell}/kg$ of I.J.T., a significant reduction of total cholesterol volum was shown in the blood serum. 3. The volume of triglyceride in the blood serum of the diabetic rats, induced by the streptozotocin, was increased in comparision to the normal flock, and with dosing $1.25m{\ell}/kg$ and $12.50m{\ell}/kg$ of I.J.T., a significant reduction of triglyceride volium was shwon in the blood serum after second and fourth week. 4. The volume of phospholipid in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparision to the normal flock, and with dosing $1.25m{\ell}/kg$ of I.J.T., a significant reduction of phospholipid volium in the blood serum was shown after first and second week. 5. The volume of total protein in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparison to the normal flock however, with dosing the I.J.T., no significant change on the volium of total protein was made in the blood serum. 6. The volume of potassium in the blood serum of the diabetic rats, induced by the streptozotocin, was increased in comparision to the normal flock however, with dosing the I.J.T., no significant change of potassium content was made in the blood serum. 7. The volume of sodium in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparision to the normal flock, and with dosing $12.50m{\ell}/kg$ of the I.J.T., a significant increase was shown in the blood serum after first week. Soyangin, accompanying with a middle and upper heat, the I.J.T. - that has a merits of cleaning up fever, solving fever, solving poison, solving thirst and restoring exhaustion - can be proved that it has a blood sugar reduction effect and it is considered that it can be meritorious for strengthening vitality, further, many other exhausting diseases, and can actively used for the cases such as thirst causing disease and a disease that causes an abnormal food hunger, thirst causing and frequent going to pass urine, in particular.
