This study investigated the clinical effectiveness and safety of sealed bleaching compared to conventional in-office bleaching using a randomized clinical trial of split arch design. Ten participants received a chairside bleaching treatment on the upper anterior teeth, and each side was randomly designated as sealed or control side. A mixture of Brite powder (PacDent, Walnut, USA), 3% hydrogen peroxide and carbamide peroxide (KoolWhite, PacDent, Walnut, USA) were used as bleaching agent. The control side was unwrapped and the experimental side was covered with a linear low density polyethylene (LLDPE) wrap for sealed bleaching. The bleaching gel was light activated for 1 hour. The tooth shades were evaluated before treatment, after treatment, and at one week check up by means of a visual shade (VS) assessment using a value oriented shade guide and a computer assisted shade assessment using a spectrophotometer (SP). The data were analyzed by paired t-test. In the control and sealed groups, the visual shade scores after bleaching treatment and at check up showed statistically significant difference from the preoperative shade scores (p < .05). The shade scores of the sealed group were significantly lighter than the control immediately after bleaching and at the check-up appointment (p < 0.05). Compared to prebleaching status, the DeltaE values at post-bleaching condition were 4.35 +/- 1.38 and 5.08 +/- 1.34 for the control and sealed groups, respectively. The DeltaE values at check up were 3.73 +/- 1.95 and 4.38 +/- 2.08 for the control and sealed groups. DeltaE values were greater for the sealed group both after bleaching (p < .05) and at check up (p < .05). In conclusion, both DeltaE and shade score changes were greater for the sealed bleaching group than the conventional bleaching group, effectively demonstrating the improvement of effectiveness through sealing.

BK virus nephropathy has emerged as an important cause of renal allograft dysfunction. Reduction in immunosuppression is the mainstay of BK virus nephropathy treatment. However, decreasing immunosuppressive medications is not sufficient for treatment of BK virus nephropathy. Therefore, there is a need for other treatment strategies such as cidofovir, leflunomide, and intravenous immunoglobulin in combination with immunosuppression reduction. Ciprofloxacin has recently been reported to have antiviral activity and decrease BK viral load in kidney transplant recipients. These findings suggest that the use of ciprofloxacin represents a valuable treatment strategy in patients with BK virus nephropathy. Here, we report on our experience with three patients who developed presumptive BK virus nephropathy after kidney transplantation, who, after 2 months of ciprofloxacin treatment, showed disappearance of BK viremia and improvement in the estimated glomerular filtration rate. Ciprofloxacin may be considered an effective treatment option for BK viremia in kidney transplant recipients.

Cardiac beriberi is caused by thiamine deficiency. Shoshin beriberi is a rare and fulminant form of cardiac beriberi characterized by hypotension, high output heart failure, lactic acidosis and anuria. Without early recognition and immediate treatment, most of these patients will be fatal. Therefore clinical diagnosis of shoshin beriberi is most important in emergency situation. We report a case of shoshin beriberi with clinical features mimicking acute coronary syndrome. Fifty year old male patient with chronic alcoholism was presented with shock, hypoxia, right heart failure and severe acidosis. Electrocardiogram showed abnormal Q in V1-3 and mild ST elevation and level of troponin I was slightly elevated. All manifestations including lactic acidosis were dramatically subsided in 18 hours by thiamine infusion. Even in developed country, shoshin beriberi can be occurred in patients with malnutrition and/or chronic alcoholism and should be differentiated with acute coronary syndrome.

Acute maxillary sinusitis is a common disorder affecting children. Untreated acute sinusitis can develop into chronic sinusitis, and complications, such as orbital cellulitis or abscess, can occur. Maxillary sinusitis of odontogenic origin is not a well-recognized condition and is frequently missed in children. As an odontogenic source of sinusitis, the dentigerous cyst is one of the most prevalent types of odontogenic cysts, and it is associated with the crown of an unerupted or developing tooth. This report concerns a nine-year-old boy who was diagnosed with maxillary sinusitis originating from a dentigerous cyst with supernumerary teeth. The boy visited our pediatric clinic presenting with rhinorrhea and nasal obstruction and was initially diagnosed with maxillary sinusitis only. With antibiotic treatment, his symptoms seemed to improve, but after 2 months, he came to our clinic with left facial swelling with persistent rhinorrhea and nasal obstruction. Radiographic examinations of the sinuses were performed, and he was diagnosed with maxillary sinusitis originating from a dentigerous cyst with supernumerary teeth. After a surgical procedure involving the removal of the dentigerous cyst with supernumerary teeth, the symptoms of sinusitis gradually diminished. There are only very few cases in the pediatric medical literature that remind us that odontogenic origin can cause maxillary sinusitis in children. Our patient can act as a reminder to general pediatricians to include dentigerous cysts in the differential diagnosis of maxillary sinusitis.

Aortic dissection most often presents with the severe chest pain and may have variable symptoms including fever. However, fever of unknown origin as the predominant manifestation of aortic dissection seems to be extremely rare. We report the case of a patient who sustained a prolonged spiking fever with unknown origin for 17 days following acute aortic dissection. The case serves as a reminder that prolonged fever may be the principal residual sequelae after aortic dissection.

BACKGROUND: Acute adaptive vascular remodeling occurs in active and unstable inflammatory plaques. It has been suggested that the adaptive coronary vascular remodeling, in patients with acute coronary syndrome (ACS), may be systemic and may show similar vascular remodeling in the carotid arteries. We investigated the ultrasonographic features of the common carotid artery (CCA) to determine whether the arterial expansive remodeling found in the coronary artery occurs in the carotid arteries of patients with ACS. METHODS: We measured lumen diameter (LD), interadventitial diameter (IAD) and intima media thickness (IMT) using a B-mode ultrasound in both common carotid arteries in patients with ACS (N=74) and chronic stable angina (CSA) (N=31). Positive remodeling was arbitrarily defined as an IMTmax >1 mm and IAD >8 mm and negative remodeling as an IMTmax >1 mm and IAD <7 mm. Other values were defined as "no remodeling" RESULTS: There were no significant differences in LD IAD and maximal IMT of the right CCA and the left CCA in comparisons between the ACS and the CSA patient groups. There were no differences for number of cases with no remodeling or differences in positive and negative remodeling in the right common carotid artery and left common carotid artery in comparisons between the ACS and CSA patient groups. . Presence of plaque in both common carotid arteries showed similar frequency in the ACS and CSA patient groups. The characteristics of carotid artery plaques were not different in the two groups. The remodeling index (IAD/LD) was correlated with IMTmax (right CCA r=0.797, p<0.001; left CCA r=0.860, p<0.001). CONCLUSIONS: The common carotid arterial structure of ACS patients was not different from that of CSA patients. Therefore, these results suggest that the expansive arterial remodeling, due to coronary inflammatory plaques, appears to take place locally rather than systemically.

BACKGROUND/AIMS: While surgical resection remains the standard of care in the treatment of upper urinary tract malignancies, nephrectomy is a risk factor for the development of chronic kidney disease (CKD). The aim of this study was to determine whether histologic evaluation of non-neoplastic kidney could enable early identification of unrecognized kidney disease and could be of prognostic value in predicting postoperative renal outcomes. METHODS: We retrospectively analyzed 51 patients with upper urinary tract malignancies who received uninephrectomy or uninephroureterectomy. A thorough pathologic evaluation of non-neoplastic kidney including special stains, immunofluorescence, and electron microscopic studies was performed. The degree of parenchymal changes was graded from 0 to 15. RESULTS: Of 51 patients, only 13 showed normal kidney pathology. Fifteen patients showed glomerular abnormalities, 14 showed diabetic nephropathy, and 11 showed vascular nephropathy. There was one case each of reflux nephropathy and chronic pyelonephritis. The median histologic score was 5 points. Only 25.4% of patients had ≤ 3 points. Score more than 5 was observed in 47.1% of patients. Postoperative estimated glomerular filtration rate (eGFR) at 3 to 36 months were obtained from 90.2% of patients, and of those, 34.8% had de novo CKD. Since no one had CKD in partial nephrectomized patients, we determined risk factors for CKD in radical nephrectomized patients. Cox regression analysis revealed that postoperative AKI, preoperative eGFR, and histologic score of non-neoplastic kidney were the independent predictors for CKD. CONCLUSIONS: We conclude that routine pathologic evaluation of non-neoplastic kidney provides valuable diagnostic and prognostic information.

BACKGROUND/AIMS: Direct-acting antiviral (DAA) therapy has been shown to achieve a high rate of sustained virologic response (SVR) and favorable outcomes in chronic hepatitis C (CHC) patients. We investigated the virologic response and its clinical impact in CHC patients. METHODS: CHC patients with compensated liver function treated with DAAs between 2016 and 2017 were included for retrospective analysis. We analyzed baseline characteristics and virologic and biochemical responses at on-treatment 4 weeks, end of treatment, and post-treatment 12 weeks. Fibrosis was measured as liver stiffness measurement by transient elastography (FibroScan). Adverse events were monitored during the treatment period. RESULTS: A total of 135 patients (61.5% with genotype [GT] 1b and 38.5% with GT 2a) were enrolled 47.4% were male, 79.3% were treatment naive, and 30.4% had cirrhosis. SVR 12 was observed in 97.6% (81/83) in the GT 1b and 98.1% (51/52) in the GT 2a; treatment with daclatasvir+asunaprevir was the most commonly used in GT 1b (55/83), and sofosbuvir+ribavirin was the most commonly used in GT 2a (49/52). The median change of liver stiffness measurement at two time points using the signed rank test was -3.2 kPa in patients who underwent transient elastography before treatment and at SVR 12 (n=25). The most common adverse events were anemia, dyspepsia, and insomnia. One GT 2a patient treated with sofosbuvir+ribavirin stopped the treatment at 8 weeks due to symptomatic bradyarrhythmia; however, he recovered spontaneously and achieved SVR 12. CONCLUSIONS: DAA treatment of chronic hepatitis C genotype 1b and 2a resulted in a high rate of sustained virologic response and improvement of liver fibrosis score.

Although the prognosis of papillary thyroid cancer (PTC) is extremely good, locoregional recurrences after initial treatment occur. Thyroglobulin (Tg) is a reliable tumor marker to detect recurrence or persistence of PTC. However, occasionally serum Tg may miss the detection of a recurrence. We report a 54-year-old female presented with hoarseness due to cervical recurrence without concomitant elevation of serum Tg and anti-Tg antibody, in contrast to extremely increased needle-washout Tg, who had undergone a total thyroidectomy and radioiodine ablation as initial therapies for PTC. Several factors causing such discrepancy between needle-washout Tg and serum Tg can be suggested including site of recurrence, volume of tumor, interference by some kind of plasma antibodies other than anti-Tg antibody, and any conformational defect of Tg protein. Among them, the most convincing explanation is that any conformational defect of Tg may lead to impaired secretion of Tg to blood. We suggest that more studies are needed to find the cause for potential mechanisms involved in PTC recurrences without increased serum Tg.
