A Case of Lemierre's Syndrome in Young Patient with Acute Peritonsillar Abscess

Lemierre's syndrome is very rare and is characterized by previous oropharyngeal infections, such as pharyngitis or peritonsillar abscess, leading to high fever, internal jugular venous thrombosis, and metastatic infections to multiple internal organs. Prompt and accurate diagnosis followed by early treatment with antibiotics is very important because its mortality is high if treatment is delayed. We report on the case of a 23-year-old female who was transferred to our hospital with a left peritonsillar abscess combined with left jugular venous thrombosis, complaining of a sore throat and left submandibular swelling, and diagnosed as Lemierre's syndrome. Finally, she was treated successfully without anticoagulants.

Predictors of side branch occlusions just after coronary stenting / 대한내과학회지

BACKGROUND: Coronary stenting is one of effective and well-accepted treatments for coronary artery disease. On the other hand, side branch occlusion (SBO) is a known complication of percutaneous transluminal coronary angioplasty (PTCA) and coronary stenting. Accordingly, this study was designed to determine the incidence, predictors and acute clinical outcomes of SBO. METHODS: Coronary angiographic findings of 45 patients who had total 98 side branches originating from the stented segments were analized before and just after coronary stenting. Bifurcation lesions were divided into 3 types : type 1, type 2, type 3 and each type was subdivided into type A with significant ostial narrowing (diameter stenosis >or=50%) and type B without significant ostial narrowing of side branches. Side branch occlusion was defined as development of total occlusion or morphologic changes from type B to type A or reduction of TIMI flow more than grade 1 compared with pre-stenting flow of side branches. RESULTS: After coronary stenting, SBO occurred in 20 of 98 side branches (20.4%). SBO was significantly related with history of previous myocardial infarction (p=0.02), threatened side branch morphology (p=0.016) and poor pre-stenting flow of side branches (p=0.014). There were no serious clinical events such as myocardial infaction and death associated with acute SBO. CONCLUSION: Acute SBO can be developed in a few stented patients. Signifiant clinical and angiographic predictors of SBO just after coronary stenting were the history of previous myocardial infarction, threatened side branch morphology and poor pre-stenting flow of side branches.

A case of carbamazepine induced acute interstitial nephritis / 대한내과학회지

Acute interstitial nephritis often caused by drugs and infection. Interstitial nephritis by drugs is a kind of idiosyncratic reaction and is caused independently of dosage. This disease developed within several days or weeks after taking medicine but improved if discontinue medication. Adrenocortical hormone may shorten the period of disease if renal dysfunction continued. Acute interstitial nephritis by carbamazepine that is used for epilepsy cure is rarely reported. A 49-year-old male was admitted to our hospital because of skin rash and decreased urine volume which developed 10 days ago. Patient was diagnosed intracranial hemorrhage 6 months ago and was taking carbamazepine because of tingling sensation to lower extremity before 2 months. At admission, blood pressure 120/80 mmHg, hemoglobin 12.6 g/dL, WBC 232,000/mm3, eosinophil count 2,790/mm3, platelet 166,000/mm3. Urine findings indicated protein 1+, blood 2+ and eosinophil was observed in microscopic examination. Abdominal sonography showed increase of both kidney size, shade of renal cortex and Resistance index (RI). Renal biopsy showed inflammatory cell consisted of lymphocyte, eosinophil in parenchyme was seen with tubular necrosis partially. Renal function was improved after carbamazepine withdrawal and adrenocortical hormone medication.

Familial Isolated Noncompaction of the Ventricular Myocardium in Asymptomatic Phase

Isolated noncompaction of the ventricular myocardium (INVM) is a rare cardiomyopathy resulting from a failure of normal endomyocardial embryogenesis and it has been categorized as a form of unclassified cardiomyopathy. The disorder is characterized by an excessively prominent trabecular meshwork with deep intertrabecular recesses. Although the disorder is sporadic, familial incidence may occur. Clinical symptoms and prognosis of INVM may differ markedly, and range from an asymptomatic course to a severe cardiac disability. The diagnostic method of choice for IVNM is echocardiography, which reveals multiple prominent trabeculations with deep intertrabecular spaces communicating with the left ventricular cavity in the middle and apical segments of the left ventricle. The authors report a case of INVM in a family in which three adult members (a brother and two sisters) were found to be affected by this disorder. They were all asymptomatic. The diagnosis of the disorder was made first in the 36-year-old brother by transthoracic echocardiography (TTE) and multidetector CT (MD CT), during the process of preoperative evaluation for surgical treatment of low back intervertebral herniated disc. TTE and MD CT showed similar and peculiar findings of INVM. Echocardiographic screening in all first-degree relatives of this patient, in order to identify asymptomatic patients, demonstrated INVM in two elder sisters.

Echocardiograpic Findings of Coronary Sinus in Heart Failure

BACKGROUND AND OBJECTIVES: The coronary sinus (CS) is a small tubular structure just below the tricuspid valve. The dilatation of the coronary sinus as well as the inferior vena cava and the hepatic vein may provide echocardiographic signs of systemic congestion. The aim of this study was to evaluate the correlation of size of coronary sinus that had abnormal echocardiographic findings with or without congestive heart failure. SUBJECTS AND METHODS: Echocardiographic examinations of coronary sinus were performed on 58 patients (M : F=20 : 38) who had abnormal echocardiographic findings with current or previous symptoms or signs of congestive heart failure (group 1), and on 63 patients (M:F=27:36) who had abnormal echocardiographic findings but that had never had symptoms or signs of heart failure(group 2) and 94 healthy volunteers (control group, M:F=52:42). The CS was mesured using a two-dimensional echocardiogram in the right ventricular inflow view (5-10 mm below the Thebesian valve at end-systolic phase). RESULTS: In the normal control group, the median size of the CS was 6.2+/-1.2 mm, and showed no difference between gender and age. The sizes of the CS in groups 1 and 2 were 9.0+/-2.3 and 6.4+/-1.3 mm, respectively. There were differences between groups 1 and the normal control group (p<0.001), and between groups 1 and 2 (p<0.001), but a slight change between group 2 and the normal control group. In group 1, the size of the coronary sinus was related with the duration of heart failure (r=0.32, p=0.016), but no correlations to body surface area, left ventricle dimension and TR peak velocity were shown. In the presence of heart failure, as diagnosed according to the size of the CS, the predictive value was high when the size of the CS exceeded 8.0 mm, with an accuracy of 84%. In heart failure, the median size of the IVC was 16.6+/-5.4 mm, the variation rate of the IVC during the respiratory cycle was 0.40+/-0.13, and the variation rate of the CS during cardiac cycle was 0.31+/-0.20. The size of the CS was not related with the size of the IVC, but there was an inverse correlation between the size of the IVC and its variation rate (r=-0.434, p=0.037). The size of the IVC was inversely correlated with the variation rate of the CS (r=-0.490, p=0.024). There was a correlation between the variation rate of the CS and that of the IVC (r=0.411, p=0.021). Comparing the groups with and without systolic flow reversal into the CS in congestive heart failure patients with tricuspid regurgitation, in the former there wrer distensions of the CS, IVC and LA dimensions and reductions in the variation rates of the CS. CONCLUSION: The measurement of the size of the CS and the variation rate of CS may provide valuable information concerning the presence and duration of congestive heart failure.
