A Case of the Soft Palate Reconstruction Using the Bilateral Palatal Mucomuscular Flap and Pharyngeal Flap after Wide Resection / 대한두경부종양학회지

The soft palate of carcinoma limited to the uvular region is infrequent among oropharyngeal cancers. The oropharynx regulates swallowing and speech through dynamic motions. Failure to reconstruct after surgical resection of the oropharynx structure can lead to permanent velopharyngeal insufficiency. Therefore, suitable reconstruction is important in establishing proper functional outcomes while maintaining oncological safety.We present a case of a 66-year-old male who was diagnosed with oropharynx cancer limited in the uvula accompanied by lymph node metastasis. After surgical resection, reconstruction was performed with the united arrangement of bilateral palatal mucomuscular flap and superiorly based posterior pharyngeal flap. There was no aspiration or reflux after feeding and epithelialization completely occurred after 1 month postoperatively. We report a successful case that the reconstruction with the local flap described above could preserve proper oropharyngeal function after primary surgery in small-sized oropharyngeal cancer.

Usefulness of Centor Score to Diagnosis of Group a Streptococcal Pharyngitis and Decision Making of Antibiotics Use / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: This study aims to verify the usefulness of Centor scores to diagnose the Group A Streptococcal pharyngitis. SUBJECTS AND METHOD: The subjects of this study were 379 patients who had been examined by the rapid antigen detection test (RADT) for Group A Streptococcus. We analyzed their medical records and laboratory test results retrospectively and compared the results of Centor symptom scores with those of RADT. Then we analyzed the association of RADT, the Centor score and the laboratory test results statistically. RESULTS: There were no correlation between the RADT results and fever, cough, tonsillar enlargement, nasal symptoms, myalgia or chilling (p>0.05). In the RADT positive group, there were more patients with tonsillar exudate, neck lymph node enlargement, tenderness and pharyngeal abscess formation significantly (p<0.05). The Centor score and C-reactive protein were significantly higher in the RADT positive group (p<0.05). CONCLUSION: The results of this study suggest that Centor symptom scores can be used to determine which antibiotics to use. The Centor score system can help reduce medical costs and detect the problematic Group A Streptococcal pharyngitis.

Food allergic reactions in the community: a questionnaire survey of caregivers

PURPOSE: Food allergies are adverse immune reactions to food. Despite their importance, there have only been a few studies conducted on situations that may cause food allergies in Korean children. This study aims to obtain basic data that are necessary to provide information on food allergies to both patients and caregivers. METHODS: In this study, a survey was conducted on 97 caregivers of patients below 18 years old. The patients' situation upon occurrence of food allergy was examined by a questionnaire. RESULTS: Approximately 89.7% of the patients were at 6 years of age or younger. The most common allergens were eggs (37%) and milk (28%) in a total of 163 cases, including multiple responses. Skin symptoms were most common (77.8%). At the time of occurrence, 85% of the patients were with their parents. As for the exposure place, house was 65%, followed by restaurant (16%), nursery (7%), and relative's or neighbor's house (4%). Exclusive of unknown cases, the most common reason of exposure was the caregiver giving the food to the patient for reconfirmation (13.6%). CONCLUSION: It is concluded that the understanding of food allergies based on this research will assist in the management of patients with food allergies.

Effects of temperature-fluctuation in a refrigerator on antioxidative index and storage qualities of various foods / 한국영양학회지

PURPOSE: The objective of this study was to examine the association of temperature-fluctuation with freshness quality in various foods. METHODS: We investigated the effects of storage conditions on antioxidant activities of cherries and romaine lettuce during storage at 0.7 ± 0.6℃, 1.2 ± 1.4℃, and 1.6 ± 2.8℃. Cherries and romaine lettuce were stored for a period of 9 days and 7 days, respectively. We also analyzed the effects of storage conditions on fresh quality of beef and salmon during storage at −0.3 ± 0.8℃, −0.6 ± 2.3℃, and −1.5 ± 4.4℃. Both of them were stored for a period of 14 days. RESULTS: The amount of water loss was highest in beef, and the microbial count was also the highest at −1.5 ± 4.4℃. In the case of salmon, there was no difference in water loss according to storage, and TBA value was significantly increased at −1.5 ± 4.4℃. Moisture retention was the highest at 0.7 ± 0.6℃ in both romaine lettuce and cherry samples. The contents of polyphenol and flavonoid were significantly higher in cherries, and content of polyphenols in romaine lettuce was significantly higher at 0.7 ± 0.6℃ (p 1.2 ± 1.4℃> 1.6 ± 2.8 ℃ over 7 days. CONCLUSION: The results indicate that temperature-fluctuation may affect qualities of foods stored in a refrigerator.

Valuation of Transient Evoked Otoacoustic Emissions and Distortion Product Otoacoustic Emissions in Tinnitus Patients with Normal Hearing / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: This study aims to verify that one of the causes of tinnitus is the malfunction of outer hair cells and, on the basis of this, to investigate the usefulness of otoacoustic emissions by performing transient evoked otoacoustic emissions (TEOAE) and distor-tion product otoacoustic emissions (DPOAE). SUBJECTS AND METHOD: Included in the study were forty-one patients who had normal hearing in the range from 0.5 to 8 kHz, and complained of unilateral tinnitus. In these patients, hearing in bilateral ears, TEOAE, DPOAE, as well as the frequency & amplitude of their tinnitus were measured. RESULTS: No statistically significant difference was found in bilateral hearing in patients who complained of unilateral tinnitus. However, TEOAE and DPOAE showed a statistically significant difference with their p-values at 0.04 and 0.004, respectively. CONCLUSION: The results of this study suggested that TEOAE testing and DPOAE testing provide an important clue for verifying that the loss of outer hair cells contributed to the development of symptoms suffered by tinnitus patients with normal hearing.

Vitamin C and antioxidant capacity stability in cherry and romaine during storage at different temperatures / 한국영양학회지

PURPOSE: The aim of this work was to study the change in antioxidant activity depending on storage temperature and storage period in romaine and cherry. METHODS: The plant material was stored at 0.7 +/- 0.6degrees C, 3.5 +/- 2.8degrees C, and 4.7 +/- 1.4degrees C. Cherry and romaine were stored for a period of 9 days and 7 days, respectively. The cherry was taken from each group of samples at regular intervals of days and the romaine was taken from each group of samples at regular intervals of 2days. Vitamin C, total polyphenol, and total flavonoid stability and antioxidant capacity including DPPH, total antioxidant capacity (TAC) were measured. RESULTS: For cherry, the levels of TAC and flavonoid were higher at the 0.7 +/- 0.6degrees C condition than other conditions (p 4.7 +/- 1.4degrees C > 3.5 +/- 2.8degrees C. CONCLUSION: The results indicated that the narrow differences and fluctuation in temperature were associated with antioxidant capacity and it might enhance the nutritional shelf life of vegetables and fruits.

Risk of cesarean section after induced versus spontaneous labor at term gestation

OBJECTIVE: To investigate whether the cesarean section (CS) rate is increased in women whose labor was induced compared to those who had spontaneous labor at term pregnancy. METHODS: A retrospective study was performed in women whose labor was either induced (induction group, n=497) or spontaneous (spontaneous group, n=878) at 37+0 to 41+6 weeks of gestation from January 2008 to June 2009. Maternal age, parity, body mass index (BMI), Bishop scores, gestational age, hypertension, diabetes, delivery mode, indications for CS, neonatal outcome were compared between the two groups. Multiple logistic regression analysis was used to examine the association between the CS rate and labor induction after adjusting for potential confounding variables. RESULTS: CS (17.3% vs. 5.3%, P<0.001) and vacuum-assisted delivery (10.7% vs. 6.4%, P<0.001) rates were significantly higher in the induction group compared to the spontaneous group. The CS rate in the induction group was higher than the spontaneous group not only in nulliparous women (25.3% vs. 8.6%, P<0.001), but also in multiparous women (3.8% vs. 0.3%, P=0.002). However, after adjusting confounding factors, the higher CS rate was significantly associated with advanced maternal age, higher BMI, lower Bishop scores and nulliparity, with no demonstrable tie to labor induction. Neonatal outcome in the two groups were comparable. CONCLUSION: Although CS rate was higher in women whose labor was induced than those who had spontaneous labor, this higher rate was associated with maternal age, BMI, Bishop scores and parity, but was not impacted by labor induction per se.

Four Cases of Acquired Aplastic Anemia Affecting an Entire Family after Ingesting Ganoderma lucidum / 대한내과학회지

We report four cases of Ganoderma lucidum-induced aplastic anemia involving members of the same family. A 33-year-old man and three family members were admitted to the hospital due to fever and pancytopenia. The illness arose after ingesting herbal wine containing G. lucidum 2 weeks earlier. A bone-marrow biopsy showed hypocellularity in three of the four family members (the exception was the one who died). They were treated with supportive management, including transfusions, granulocyte colony stimulating factor, and empirical antibiotics for neutropenic fever. The pancytopenia improved 4-5 weeks after the symptoms first appeared.

The efficacy of low-dose transdermal fentanyl in opioid-naive cancer patients with moderate-to-severe pain

BACKGROUND/AIMS: Little is known about the efficacy of low-dose transdermal fentanyl (TDF) patches in opioid-naive patients with moderate-to-severe cancer pain. METHODS: This study had an open-label, prospective design, and was conducted between April 2007 and February 2009 in seven tertiary cancer hospitals; 98 patients were enrolled. TDF was started using a low-dose formulation (12.5 microg/hr), and the dose was adjusted according to the clinical situation of individual patients. Pain intensity, the TDF doses used, and adverse events (AEs) were monitored over 4 weeks. Data were analyzed using the intent-to-treat and per-protocol principles. RESULTS: Of the 98 patients enrolled, 64 (65%) completed the study. The median pain intensity decreased from 6.0 to 3.0 (p < 0.001) at the follow-up visit. The efficacy of low-dose TDF on pain relief was consistent across groups separated according to gender (p < 0.001), age (p < 0.001), metastasis (p < 0.001), previous treatment (p < 0.001), and baseline pain intensity (p < 0.001). The decrease in pain intensity was significantly greater in the severe group compared with the moderate group (mean +/- SD, 5.10 +/- 2.48 vs. 2.48 +/- 1.56; p < 0.001). TDF dose (27.8 microg/hr vs. 24.8 microg/hr, p = 0.423) and the mean treatment time (7.5 days vs. 7.9 days, p = 0.740) required for pain control were not different between the two pain-intensity groups. Patients had AEs of only mild or moderate intensity; among these, nausea (38%) was the most common, followed by vomiting (22%) and somnolence (22%). CONCLUSIONS: Low-dose TDF was an effective treatment for patients with cancer pain of moderate-to-severe intensity. Further randomized trials assessing the efficacy of TDF for severe pain and/or optimal starting doses are warranted.

A Case of Metastatic Low-Grade Endometrial Stromal Sarcoma Treated with Letrozole after Ovarian Ablation by Radiotherapy / Journal of the Korean Cancer Association, 대한암학회지

A 50-year-old woman was admitted to our hospital due to multiple lung nodules detected incidentally on a chest X-ray. A video-assisted thoracoscopic lung biopsy revealed low-grade endometrial stromal sarcoma (LG-ESS). She had undergone a simple hysterectomy 1 year earlier owing to a diagnosis of adenomyosis. A review of her previous hysterectomy specimen showed not endometriosis but LG-ESS. According to the patient's levels of serum follicle stimulating hormone and estradiol, she was in the premenopausal state with retained and normally functioning ovaries. She then underwent ovarian ablation by radiotherapy, after which she was administered 2.5 mg of letrozole once per day. Three months later, the size of the metastatic nodules in both lungs had decreased. The patient was followed up for 24 months while continuing on letrozole, and maintained a partial remission. We report herein on a case of metastatic LG-ESS treated with letrozole after ovarian ablation by radiotherapy.

Intramedullary Spinal Cord Metastasis From Rectal Cancer

Intramedullary spinal cord metastasis (ISCM) is an uncommon condition of the central nervous system (CNS) cause by systemic malignant tumors. Most ISCM cases are known to occur in patients with lung cancer and breast cancer; however, ISCM also very rarely occurs in patients with colorectal cancer. For the first time in Korea, we experienced a case of ISCM arising from rectal cancer, where a 75-year-old man presented with an abruptly-developed left-foot drop and numbness in both legs. The patient had lung metastases from rectal cancer that had been treated with chemotherapy. Magnetic resonance imaging revealed an intramedullary nodular lesion at the T12 level. ISCM was diagnosed and treated with steroids and radiotherapy. The patient's neurological symptoms were relieved for a while after treatment, but his condition deteriorated progressively. He died 4 months after ISCM had been diagnosed.

Comparison of Distress and Body Image according to the Stages of Cancer Survivorship in Gynecological Cancer Patients

PURPOSE: This study was to compare distress and body image according to the stages of cancer survivorship in patients with gynecological cancer. METHODS: The subjects were 231 patients who visited for treatment or follow-up care at a university medical center in a city, Korea. These participants were divided into three groups based on the stages of cancer survivorship. The data were collected from November, 18, 2010 to January, 28, 2011 with the use of a structured questionnaire which measured the distress thermometer (DT) and problem list (PL), and body image. RESULTS: Distress scores were not significantly different among three stages of cancer survivorship, but the patients of acute cancer survival experienced the distress of 4.50 point of moderate level (DT>4). The problem list of distress score was significantly higher in the acute cancer survival than long-term cancer survival (F=3.04, p=.048). The score of body image was significantly lower in the acute cancer survival stage than long-term cancer survival (F=3.69, p=.026). CONCLUSION: Gynecological cancer patients in the acute cancer survival among the three stages will to need to provide a nursing intervention to decrease distress and improve body image.

Thrombolytic Therapy Using Urokinase for Management of Central Venous Catheter Thrombosis

PURPOSE: The management of central venous catheters (CVCs) and catheter thrombosis vary among centers, and the efficacy of the methods of management of catheter thrombosis in CVCs is rarely reported. We investigated the efficacy of bedside thrombolysis with urokinase for the management of catheter thrombosis. MATERIALS AND METHODS: We retrospectively reviewed data from patients who had undergone CVC insertion by a single surgeon in a single center between April 2012 and June 2014. We used a protocol for the management of CVCs and when catheter thrombosis was confirmed, 5,000 U urokinase was infused into the catheter. RESULTS: A total of 137 CVCs were inserted in 126 patients. The most common catheter-related complication was thrombosis (12, 8.8%) followed by infection (8, 5.8%). Nine of the 12 patients (75%) with catheter thrombosis were recanalized successfully with urokinase. The rate of CVC recanalization was higher in the peripherally inserted central catheter (PICC) group (87.5%) than the chemoport group (50%). Reintervention for catheter-related thrombosis was needed in only 2.2% of patients when thrombolytic therapy using urokinase was applied. Age <60 years (P=0.035), PICC group (P=0.037) and location of the catheter tip above the superior vena cava (P=0.044) were confirmed as independent risk factors for catheter thrombosis. CONCLUSION: Thrombolysis therapy using urokinase could successfully manage CVC thrombosis. Reintervention was rarely needed when a protocol using urokinase was applied for the management of CVC thromboses.

Two Cases of Treatment with Intrathecal Rituximab for Primary Central Nervous System Lymphoma / 대한내과학회지

Primary central nervous system lymphoma (PCNSL) is an aggressive non-Hodgkin's lymphoma (NHL), usually composed of diffuse large B-cells. Although rituximab is known for its curative effect on B-cell NHL, data on the use of intrathecal rituximab for PCNSL are limited. In this report, we present two patients showing relapsed PCNSL with lymphomatous meningitis. Both patients were refractory to conventional methotrexate-based intrathecal chemotherapy. However, after intrathecal rituximab with or without conventional intrathecal chemotherapy, both patients showed stable disease on magnetic resonance brain imaging and cerebrospinal fluid analysis. There were no serious adverse events during each of 3 and 6 cycles with intrathecal rituximab immunotherapy.

Developed diplopia and ptosis due to a nonfunctioning pituitary macroadenoma during pregnancy

Physiologic pituitary enlargement is common during normal pregnancy. However, symptoms such as diplopia, blurred vision and headache resulting from physiologic pituitary enlargement are very rare during pregnancy. A 39-year-old woman complained of sudden diplopia and left eye ptosis at 33th weeks of gestation. An magnetic resonance imaging (MRI) demonstrated the pituitary enlargement compressing the optic chiasm. Notwithstanding the medication of bromocriptine, her symptoms did not regress during pregnancy. At 5 months after delivery, her symptoms dramatically resolved without any surgery, and her visual acuity was normalized. Her MRI scan also revealed more decreased size of pituitary gland compared to antenatal MRI. We report a case of visual loss due to the physiologic pituitary enlargement of nonfunctioning adenoma during pregnancy, which regressed spontaneously after delivery without any surgery.

Delivering bad news to a patient: a survey of residents and fellows on attitude and awareness / 한국의학교육

PURPOSE: Delivering bad news (DBN) to a patient or patient's family is one of the most difficult tasks for physicians. As a complicated task, DBN requires better than average communication skills. This study investigated trainee's attitude and awareness of DBN based on a self-assessment of their experiences and performance in practice. Survey subjects were also asked to assess their perception and the need for education in conducting DBN. METHODS: A survey was carried out on their experiences with DBN, how they currently deal such situations, how they perceive such situations and the need for education and training programs. A SPIKES protocol was used to assess how they currently deal with DBN. RESULTS: One hundred one residents and fellows being trained in a teaching hospital participated in the survey. Around 30% had bad experiences due to improperly delivered bad news to a patient. In terms of self-assessment of how to do DBN, over 80% of trainees assessed that they were doing DBN properly to patients, using a SPIKE protocol. As for how they perceived DBN, 90% of trainees felt more than the average level of stress when they do DBN. About 80% of trainees believed that education and training is much needed during their residency program for adequate skill development regarding DBN. CONCLUSION: We suggest that education and training on DBN may be needed for trainees during the residency program, so that they could avoid unnecessary conflict with patients and reduce stress from DBN.

Extramedullary Solitary Plasmacytoma of the Lymph Nodes / 대한내과학회지

Extramedullary plasmacytomas are uncommon malignant neoplasms that can occur in any organ. They arise most frequently from the upper aerodigestive tract. Lymph nodes are exceedingly rare sites of extramedullary plasmacytomas. Most extramedullary plasmacytomas of the lymph node arise in the cervical lymph nodes. Here, we report a case of an extramedullary plasmacytoma of the lymph node arising from a cervical lymph node. A 43-year-old male patient was admitted to our hospital and presented with a non-tender mass on the left side of his neck, which had been growing slowly for 1 month. The mass was excised. The pathology showed diffuse infiltration of immature plasma cells that were encapsulated by a layer of lymphoid cells, indicating an extramedullary plasmacytoma. He was treated with local radiation of the left cervical area. As of March 2009, he is doing well and shows no further evidence of the disease.

Pericardial Amyloidosis Associated with Light-chain Myeloma / 대한내과학회지

Amyloidosis is characterized by the deposition of amyloid fibrils, which cause both functional and structural damage to organs. Cardiac involvement with amyloids is a common cause of secondary cardiomyopathy and leads to congestive heart failure. Pericardial amyloidosis usually occurs at the late or terminal stage of the disease after myocardial involvement, but it is extremely rare for pericardial amyloidosis to proceed with myocardial involvement. Here, we report a rare case of a 66-year-old patient with light-chain myeloma, who presented with pericardial effusion but no evidence of cardiomyopathy.

Management of Non-pain Symptoms in Terminally Ill Cancer Patients: Based on National Comprehensive Cancer Network Guidelines / 한국호스피스완화의료학회지

Most terminally ill cancer patients experience various physical and psychological symptoms during their illness. In addition to pain, they commonly suffer from fatigue, anorexia-cachexia syndrome, nausea, vomiting and dyspnea. In this paper, I reviewed some of the common non-pain symptoms in terminally ill cancer patients, based on the National Comprehensive Cancer Network (NCCN) guidelines to better understand and treat cancer patients. Cancer-related fatigue (CRF) is a common symptom in terminally ill cancer patients. There are reversible causes of fatigue, which include anemia, sleep disturbance, malnutrition, pain, depression and anxiety, medical comorbidities, hyperthyroidism and hypogonadism. Energy conservation and education are recommended as central management for CRF. Corticosteroid and psychostimulants can be used as well. The anorexia and cachexia syndrome has reversible causes and should be managed. It includes stomatitis, constipation and uncontrolled severe symptoms such as pain or dyspnea, delirium, nausea/vomiting, depression and gastroparesis. To manage the syndrome, it is important to provide emotional support and inform the patient and family of the natural history of the disease. Megesteol acetate, dronabinol and corticosteroid can be helpful. Nausea and vomiting will occur by potentially reversible causes including drug consumption, uremia, infection, anxiety, constipation, gastric irritation and proximal gastrointestinal obstruction. Metoclopramide, haloperidol, olanzapine and ondansetron can be used to manage nausea and vomiting. Dyspnea is common even in terminally ill cancer patients without lung disease. Opioids are effective for symptomatic management of dyspnea. To improve the quality of life for terminally ill cancer patients, we should try to ameliorate these symptoms by paying more attention to patients and understanding of management principles.
