Papillary Cannulation Facilitated by Submucosal Saline Injection into an Intradiverticular Papilla

Endoscopic retrograde cholangiopancreatography (ERCP) of the intradiverticular papilla with its invisible orifice remains challenging. Several techniques have been introduced to evert the papillary opening to facilitate cannulation. A 79-year-old woman with bile duct stones underwent ERCP, which revealed that the papilla was located inside a large diverticulum and tended to rotate inward with a trial of papillary cannulation. Submucosal papillary injection of 3 cc of normal saline was performed at 3 and 9 o’clock. Eversion and fixation of a papilla in the diverticulum with this technique allowed selective cannulation of the biliary tree. Stones were retrieved after endoscopic papillary balloon dilation without complications. She had an uneventful post-procedural course. Our findings suggest that submucosal saline injection technique is safe and effective for selective cannulation and can be recommended when cannulation is very difficult because of an intradiverticular papilla.

Interstitial Nephritis Caused by Anorexia Nervosa in Young Male; A Case Report and Literature Review

Severe eating disorders characterized by repetitive episodes of purging and vomiting can occasionally trigger acute kidney injury. However, interstitial nephritis induced by episodes of repeated vomiting has rarely been reported, and the pathophysiology of this entity remains unknown. A 26-year-old man was admitted to our hospital because of known hypokalemia. His serum electrolyte profile showed: sodium 133 mEq/L, potassium 2.6 mEq/L, chloride 72 mEq/L, total carbon dioxide 50 mEq/L, blood urea nitrogen/creatinine ratio (BUN/Cr) 21.9/1.98 mg/dL, and magnesium 2.0 mg/dL. Arterial blood gas analysis showed: pH 7.557, partial pressure of carbon dioxide 65.8 mmHg, and bicarbonate 58.5 mEq/L. His urinary potassium concentration was 73.2 mEq/L, and Cr was 111 mg/dL. Renal biopsy revealed acute tubular necrosis and tubulointerstitial nephritis with a few shrunken glomeruli. Repeated psychogenic vomiting may precipitate acute kidney injury and interstitial nephritis secondary to volume depletion and hypokalemia. Serum electrolyte levels and renal function should be carefully monitored in patients diagnosed with eating disorders to prevent tubular ischemia and interstitial nephritis.

A Case of Treatment with Steroid and Hydrochloroquine of Thrombocytopenia in Primary Sjögren's Syndrome / 고신대학교의과대학학술지

Sjögren's syndrome is a systemic autoimmune disease characterized by sicca symptoms and extraglandular manifestations. Anemia, leukopenia, thrombocytopenia and lymphoproliferative disorders are well-known extraglandular, hematological complications of Sjögren's syndrome. These hematologic alterations are usually mild and respond well with steroid therapy. We report a case of a 52-year-old female patient who was initially presented with thrombocytopenia. The patient was then diagnosed with primary Sjögren's syndrome and initially treated with steroid. The patient's platelet count was decreased when steroid was tapered. The dose of steroid could be effectively reduced after combined medication with hydroxychloroquine.

A Case of Infectious Arthritis due to Staphylococcus lugdunensis in Seronegative Rheumatoid Arthritis, Diabetes Mellitus Patient, after Intraarticular Hyaluronic Acid Injection

Intra-articular hyaluronic acid injections for symptomatic treatment of osteoarthritis are widely used but can result in complications, such as infectious arthritis. Staphylococcus lugdunensis is a common normal skin flora but can cause severe infectious disease, such as infective endocarditis. We present the first report of infectious arthritis caused by methicillin-sensitive S. lugdunensis after intra-articular hyaluronic acid injection in an immunocompromised patient in Korea.

Bordetella bronchiseptica Respiratory Infection in the Immunosuppressed Patient / 대한내과학회지

Bordetella bronchiseptica is a common cause of respiratory disease in animals but is a rare cause of human infection. Furthermore, most patients with Bordetella bronchiseptica infections are immunocompromised. The Bordetella bronchiseptica organism can cause pneumonia, septicemia, and peritonitis in humans with impaired immune systems. Additionally, it can lead to a life-threatening infection patients who have an underlying debilitation or impaired immunity. The respiratory tract is the most common site of infection. Sixty-two human cases of Bordetella bronchiseptica have been published in the English literature, and 84 % hadof the cases were associated with pneumonia or bronchitis. However, only one case of Bordetella bronchiseptica has been reported in South Korea, and it was associated with peritonitis. In the current study, we report a case of Bordetella bronchiseptica pneumonia diagnosed in an immunocompromised patient.

Long-Term Survival after T-cell Lymphoblastic Lymphoma Treated with One Cycle of Hyper-CVAD Regimen / Journal of the Korean Cancer Association, 대한암학회지

T-lymphoblastic lymphoma (T-LBL) is a rare form of aggressive non-Hodgkin's lymphoma. The standard approach for management of T-LBL involves intensive multiagent chemotherapy regimens for induction and consolidation phases with central nervous system prophylaxis and a maintenance phase lasting 12-18 months. We report on a case of long-term survival after one cycle of hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (hyper-CVAD) and high-dose methotrexate. A 30-year-old woman diagnosed with T-LBL with a large mediastinal mass underwent one cycle of hyper-CVAD. Four days after the start of treatment, the mediastinal mass was markedly reduced. Treatment continued with one cycle of consolidation chemotherapy, comprising high-dose methotrexate and high-dose cytarabine. The patient then refused all further chemotherapeutic treatment. Seven years have passed without relapse.

Positional symmetry of porion and external auditory meatus in facial asymmetry / 대한악안면성형재건외과학회지

BACKGROUND: The porion (Po) is used to construct the Frankfort horizontal (FH) plane for cephalometrics, and the external auditory meatus (EAM) is to transfer and mount the dental model with facebow. The classical assumption is that EAM represents Po by the parallel positioning. However, we are sometimes questioning about the possible positional disparity between Po and EAM, when the occlusal cant or facial midline is different from our clinical understandings. The purpose of this study was to evaluate the positional parallelism of Po and EAM in facial asymmetries, and also to investigate their relationship with the maxillary occlusal cant. METHODS: The 67 subjects were classified into three groups. Group I had normal subjects with facial symmetry (1.05 +/- 0.52 mm of average chin deviation) with minimal occlusal cant (<1.5 mm). Asymmetry group II-A had no maxillary occlusal cant (average 0.60 +/- 0.36), while asymmetry group II-B had occlusal cant (average 3.72 +/- 1.47). The distances of bilateral Po, EAM, and mesiobuccal cusp tips of the maxillary first molars (Mx) from the horizontal orbital plane (Orb) and the coronal plane were measured on the three-dimensional computed tomographic images. Their right and left side distance discrepancies were calculated and statistically compared. RESULTS: EAM was located 10.3 mm below and 2.3 mm anterior to Po in group I. The vertical distances from Po to EAM of both sides were significantly different in group II-B (p = 0.001), while other groups were not. Interside discrepancy of the vertical distances from EAM to Mx in group II-B also showed the significant differences, as compared with those from Po to Mx and from Orb to Mx. CONCLUSIONS: The subjects with facial asymmetry and prominent maxillary occlusal cant tend to have the symmetric position of Po but asymmetric EAM. Some caution or other measures will be helpful for them to be used during the clinical procedures.

Three-dimensional functional unit analysis of hemifacial microsomia mandible-a preliminary report / 대한악안면성형재건외과학회지

BACKGROUND: The aim of this study was to present three-dimensional (3D) structural characteristics of the mandible in the hemifacial microsomia. The mandible has six distinct functional units, and its architecture is the sum of balanced growth of each functional unit and surrounding matrix. METHODS: In order to characterize the mandibular 3D architecture of hemifacial microsomia, we analyzed the mandibular functional units of four hemifacial microsomia patients using the 3D reconstructed computed tomography (CT) images. And we compared the functional unit size between affected and non-affected side. RESULTS: The length of condyle and angle showed significant differences between affected and non-affected sides. However, the length of mandibular body showed insignificant differences. The size differences between affected and non-affected side were observed at the condyle, angle, and body in descending order. CONCLUSIONS: This preliminary study suggests that the main etiopathogenic units are condyle and angle in the hemifacial microsomia mandible. Further investigation with the increased number of subjects will be helpful to establish treatment modality by etiopathogenic targeting of hemifacial microsomia.

Mycotic Abdominal Aortic Aneurysm Caused by Bacteroides Thetaiotaomicron and Acinetobacter Lwoffii: The First Case in Korea / 감염과화학요법

Mycotic aneurysms are uncommon, but are fatal without appropriate management. Previous reports have shown that anaerobes and gram-negative organisms are less common but more dangerous than other causative agents of mycotic aneurysm. We report the case of a 60-year-old man with poorly controlled diabetes mellitus and atherosclerosis in the aorta, and a 10-day of history of lower abdominal pain and fever. This man was diagnosed with an uncommon abdominal aorta mycotic aneurysm caused by Bacteroides thetaiotaomicron and Acinetobacter lwoffii. The aneurysm was successfully treated with antibiotics therapy and aorto-bi-external iliac artery bypass with debridement of the infected aortic wall. We present this case together with a review of the relevant literature.

A Case on Streptococcal Pneumonia Associated with Leptomeningitis, Osteomyelitis and Epidural Abscess in a Patient with AIDS / 결핵및호흡기질환

Patients with acquired immunodeficiency syndrome (AIDS) are at higher risks of bacterial pneumonia than the general population, and the pathogen is the most commonly involved Streptococcus pneumoniae. We hereby report a case of pneumococcal pneumonia associated with leptomeningitis, osteomyelitis and epidural abscess in a patient with AIDS. He is being successfully treated with ampicillin/sulbactam and clindamycin. And because the pneumococcal infection is usually associated with morbidity and mortality rates in the setting of AIDS, we should consider for pneumococcal vaccinations among the AIDS populations.

A Case of Different Organ Responses to Immunosuppressive Therapy In a Microscopic Polyangiitis Patient with Interstitial Lung Disease / 대한내과학회지

Microscopic polyangiitis (MPA) is an idiopathic autoimmune disease characterized by systemic vasculitis associated with antineutrophil cytoplasmic autoantibodies. Interstitial lung disease is a less recognized manifestation of MPA and has a poor prognosis. A 61-year-old man presented with persistent cough, sputum and dyspnea. Laboratory examination revealed microscopic hematuria and renal insufficiency. Perinuclear anti-neutrophil cytoplasmic autoantibodies were positive according to serological testing. Computed tomography scans showed bibasilar reticulation and honeycombing in a peripheral distribution. Therefore, renal biopsy was performed, and MPA was diagnosed. After treating with corticosteroids and immunosuppressive agents, the patient had a complete renal response but progressive interstitial lung disease. We report a case of MPA presenting with interstitial lung disease in which the patient experienced different responses in each organ.

Pathological differences between forceps biopsy specimens and endoscopic resection specimens in early gastric cancer patients / 고신대학교의과대학학술지

OBJECTIVE: Endoscopic resection(ER) is effective therapy on EGC and which is treated according to the histological diagnosis of forcep biopsy. But sometimes the histological diagnosis of forcep biopsy and post-ER does not match with each other and it might lead to wrong treatment. The aim of this study is to find the frequency of histologic differences between forcep biopsy and post-ER, and to confirm the characteristics of lesions which make errors. METHODS: We selected the confirmed cancer cases of 141 patients of 1359 gastric tumor lesions which were treated under the ER in Eulji university hospital from May 2005 to March 2013. They were sorted by the age and sex of patient, location of lesion, present of ulcer and depression to identify the discordance between forcep biopsy and ER. The discordant group was compared with non-cancer-diagnosed controlled group, retrospectively. RESULTS: 70 cases(5.5%) of 1283 cases of "cancer negative" in forceps biopsy were found to be diagnosed cancer on final diagnosis of cancer by post-ER result. In this discordant group showed characteristics of bigger size that are with more frequently in tumor size >==15mm(17.9% vs. 31.4%, p=0.03), have depressed lesion(14.3% vs. 41.4%, p==15mm, presented with depressed lesion and ulceration, we should consider combined cancer, even the result of forcep biopsy was negative. Therefore, more careful and accurate resection should be taken with characters listed above.

A Case of Systemic Lupus Erythematosus Occurring after H1N1 Influenza Vaccination / 대한내과학회지

The recent worldwide outbreak of H1N1 has led to the universal administration of H1N1 influenza vaccination, including in South Korea. Several complications have been reported with use of H1N1 influenza vaccine, but systemic lupus erythematosus (SLE) has not been reported as a complication until now. Here, we report a case of SLE occurrence after H1N1 influenza vaccination. A 17-year-old girl who had not been diagnosed with SLE was hospitalized with fever, myalgia, and arthralgia after H1N1 influenza vaccination. Laboratory tests revealed increased levels of antinuclear antibody and anti-ds-DNA antibody, and decreased levels of C3 and C4 as well as proteinuria. The pathological findings confirmed a diagnosis of lupus nephritis. The patient was treated with high-dose corticosteroid and hydroxychloroquine. This is the first report of SLE following H1N1 influenza vaccination in South Korea.

Reconsideration of decision making for third molar extraction

INTRODUCTION: Third molar extraction is one of the most common procedures in oral and maxillofacial surgery. The impacted third molar causes many pathological conditions, such as pericoronitis, caries, periodontitis, resorption of adjacent teeth, and cyst or tumors associated with impacted teeth. Extraction is often considered the treatment of choice for impacted lower third molars. On the other hand, imprudent extraction of deeply impacted third molars can cause permanent complications, such as inferior alveolar nerve damage. Therefore, guidelines for the extraction of lower third molars should be set to prevent embarrassing complications. This study examined the indication and current trends of the extracted lower third molars in the dental hospital of a dental college. MATERIALS AND METHODS: 557 extracted third molars were evaluated at the department of oral and maxillofacial surgery of Yonsei University. The chief complaint, diagnosis, age and degree of impaction were analyzed to determine the tendency for the extraction of asymptomatic lower third molars. RESULTS: The percentage of asymptomatic third molars was 40.8%. In cases of full impacted tooth or full erupted tooth, the percentage of asymptomatic teeth was more than 50% (52.4% and 54.3, respectively). Among those partially impacted teeth, 73.1% of them showed symptoms, such as pain, tenderness and swelling. In terms of age, pericoronitis was evident at a younger age, and dental caries/periodontitis was the main cause of removal in those aged over 50. Twenty nine cases (1.6%) had teeth associated with pathological changes. CONCLUSION: The incidence of pathological changes to the lower third molar was relatively low. Surgical extraction is recommended in cases of partially impacted teeth. In Korea, the incidence of asymptomatic third molar extraction was relatively higher than in European countries. More careful attention would be desirable to consider the risks and benefits of lower third molar extraction.

Predicting Factors Associated with Drug Compliance in Psychiatric Outpatients of a University Hospital / 대한정신약물학회지

OBJECTIVE: Drug compliance is closely related to progress and prognosis of psychiatric disease. We investigated drug compliance in psychiatric outpatients and factors that influence their compliance. METHODS: Patients who visited a university hospital were asked about drug information and drug compliance using questionnaires. Medical records of the patients were reviewed. Demographic variables, clinical characteristics and drug compliance related variables were compared between non-compliance group and compliance group. Logistic regression analysis was performed to clarify predictors of poor compliance. RESULTS: One hundred eighty one patients participate in this study. 150 patients (82.9%) were compliance group, 31 patients (17.1%) were included in non-compliance group. Patient-related, illness-related and treatment-related factors, DAI total score and knowledge of side effect did not show any difference in both groups. However, illness severity was relatively higher in non-compliance group (p = 0.070) and patient's satisfaction about explanation of side effect was lower in noncompliance group (p = 0.061). Moreover, patients who negatively answered for question about negative recognition to psychiatric medication in DAI questionnaire were more common in non-compliance group (p = 0.075). In logistic regression, answering negatively to question about negative recognition to psychiatric medication in DAI questionnaire was related to non-compliance, but did not reached statistical significance (p = 0.086). CONCLUSION: This study suggests that improving negative recognition about psychiatric medication through drug education and good doctor patient relationship could enhance drug compliance.

Transoral Treatment of Eagle's Syndrome: 2 Case Report

Proposal for Pretreatment of Patients in Antiplatelet Therapy Requiring Minor Oral Surgery

PURPOSE: Many patients in anti-platelet therapy have been consulted for bleeding risks before minor oral surgery. However, there has not been an established pretreatment protocol for treating these patients. The purpose of this study is to make a protocol for the preoperative management for patients in anti-platelet therapy. PATIENTS AND METHODS: The existed consultation pattern of patients was examined in the Department of Oral and Maxillofacial Surgery, Yonsei Dental Hospital. Based on the observation, a protocol including classification of medical status of patients and the type of oral surgery in need was introduced. This protocol had been performed for 6 months. RESULT: Following this protocol, the frequency of consultation for bleeding risk was decreased. The number of minor oral surgeries with concurrent anti-platelet therapy was increased. There was no severe bleeding event observed among minor oral surgeries that were performed while maintaining anti-platelet therapy. CONCLUSION: This protocol can be used as a guideline for clinical practice of patients in anti-platelet therapy requiring minor oral surgery.

Eruption and Autotransplantation of a Permanent Tooth Related to Dentigerous Cyst in Mixed Dentition

PURPOSE: Dentigerous cyst is the most common intra-osseous lesion of the jaw. Dentigerous cysts can cause delays in eruption of the affected permanent tooth in mixed dentition. It has been suggested that the affected permanent tooth could be erupted spontaneously after the dentigerous cyst was enucleated. But in some cases, orthodontic treatment or autotransplantation technique is known to be required. This study reviews previously performed prognoses of affected permanent teeth, which will lead to a more efficient treatment plan. PATIENTS AND METHODS: With 28 patients who have undergone cyst enucleation and 10 patients who have undergone autotransplantation, the prognosis of permanent teeth was observed. RESULTS: After cyst enucleation, spontaneous eruption of a permanent tooth was observed in 56.3% patients, orthodontic treatment was performed in 25% patients. The success rate of autotransplantation was 60.0 %. DISCUSSION: The first choice for treatment of dentigerous cyst in mixed dentition is to guide spontaneous eruption of permanent teeth. For cases without enough eruption space, the orthodontic treatment should be considered. Autotransplantation should be considered when the spontaneous eruption is not expected. It should be considered that the rate of successful autotransplantation is decreased on maxilla anterior area.

Clinical Features and Musculoskeletal Anomalies in VATER Association / 대한정형외과학회잡지

PURPOSE: To analyze congenital anomalies, especially musculoskeletal anomalies, in patients with VATER association. MATERIALS AND METHODS: Fifteen patients who were admitted to our hospital from Jan. 1990 to Dec. 1997, and with more than three of the major criteria of VATER association, were included in this study. Major criteria were vertebral anomalies, imperforated anus, tracheoesophageal anomalies, radial side anomalies, renal anomalies and congenital heart anomalies. RESULTS: Seven boys and 8 girls with VATER association were included. The follow-up period, except for 4 cases who died, was 6 years and 8 months on average (from 2 years and 3 months to 12 years and 7 months). Twelve patients had congenital heart disease, and 11 patients had tracheoesophageal anomalies and imperforated anus, 8 had vertebral anomalies, and radial side anomalies and renal anomalies were detected in 6 patients each. Congenital rib anomalies were the most common. CONCLUSION: Orthopedic surgeons who address vertebral or radial side anomalies in patients with VATER association need to predict other possible anomalies and should have enough knowledge to treat these conditions.

ACL Reconstruction Using Autologous Quadriceps Tendon / 대한정형외과학회잡지

PURPOSE: We report upon our experience of ACL reconstruction using autologous central quadriceps tendon. MATERIALS AND METHODS: Twenty-six patients with ACL reconstruction using autologous central quadriceps tendon, who were followed up at least one year, were included in the present study. The clinical results including, anterior laxity, range of motion, anterior knee pain, and quadriceps power were evaluated using, the Lachman test, anterior drawer test, pivot shift test, Lysholm score, KT-2000 study and Cybex II dynamometer. RESULTS: The results of the Lachman, anterior drawer and pivot shift tests were markedly improved. The side to side difference of maximal manual translation measured by KT-2000 reduced from an average 7.5 mm preoperatively to 2.5 mm postoperatively and the Lysholm score improved significantly from 69.4 preoperatively to 86.2 postoperatively. No patient complained of a newly developed anterior knee pain. CONCLUSION: ACL reconstruction using autologous central quadriceps tendon showed satisfactory clinical results without anterior knee pain or donor site morbidity. Autologous central quadriceps tendon may be a resonable source of graft in ACL reconstruction.
