We report a case of 50-year-old man with hyalinized hemangioma of the liver. This tumor was detected incidentally during surgical operation for gall stone and was preoperatively diagnosed as intrahepatic stone. A 2.5 2 cm sized gray to white hard mass was found in the left lobe of the liver. Histologically, the tumor was composed of dense collagenous tissue with marked hyalinization, calcification, and ossification admixed with scattered sclerotic vessels. Abundunt elastic fibers were noted in the hyalinized tissue. Totally hyalinized hemangioma is very uncommon and could be erroneously diagnosed as a malignant tumor by preoperative radiologic examination.

PURPOSE: To determinate the effect of clinical factors on the duration of hematuria after transurethral resection of the prostate (TURP). PATIENTS AND METHODS: Seventy-three men who underwent TURP were analyzed retrospectively to determine the time of cessation of hematuria. The effect of various clinical factors (weight of tissue resected, operation duration, and resection rate) was assessed. RESULTS: Microscopic hematuria ceased in 37%, 70%, 87%, and 96% of patients at the end of the second, fourth, sixth, and eighth weeks, respectively. The duration of postoperative bleeding was significantly associated with the weight of tissue resected and the operation time (p<0.014 and <0.001, respectively). CONCLUSIONS: Postoperative hematuria usually stopped within 4 weeks of TURP. This period was directly related to the size of the gland resected and the duration of the procedure.

The principles determining the primary localization of lesions in fixed drug eruption (FDE) are still unknown. Studies investigating the predilection areas in FDE have indicated drug-related, trauma-related, or inflammation-related specific site involvement, as well as visceracutaneous reflex-related specific site involvement. The importance of viscerocutaneous reflexes for the location of dermatoses was first recognized in the 1960s. Head's zones are viscerocutaneous reflex projection fields on the skin that extend over certain dermatomes and possess a reflex-associated maximal point. Recently, in a Turkish collective of patients, three women with the primary location of FDE lesions on the maximal points of Head's zones were presented. We also experienced 3 cases with FDE where the lesions were located at specific sites (buttocks), the so-called maximal points of Head's zones, which are known to be the most active dermatomal areas of an underlying visceral pathology. An underlying internal disturbance (ureter stone, pyelonephritis and chronic pelvic inflammatory disease) was found in all 3 patients, corresponding to the organ-related maximal point of Head's zones in each case. In conclusion, the primary location of FDE lesions on the maximal points of Head's zones revealed relevant organ disorders with corresponding projection fields.

BACKGROUND: Studies using a transcranial Doppler (TCD) to establish cerebral vasoreactivity (CVR) have mostly focused on the anterior circulation. The purpose of this study is not only to evaluate the feasibility of the power motion mode Doppler (PMD) with a probes fixating device, but also to simultaneously measure the CVR between the middle cerebral artery (MCA) and the basilar artery (BA) during hypercapnea simulated by the rebreathing technique. METHODS: Twenty eight healthy volunteers were enrolled. Baseline hemodynamic values (heart rate, blood pressure) were measured while volunteers sat in a comfortable position for 5 minutes. The TCD was performed in two steps. First, velocities and spectra of the MCAs were simultaneously monitored. Then, the velocities and spectra of the MCA and BA were simultaneously monitored by a headset that included an anterior-posterior probes fixating device. The equation for CVR was ([maximum mean velocity baseline mean velocity] x 100/baseline mean velocity). RESULTS: Baseline mean velocities were revealed as follows: (64.0+/-13.7, 65.0+/-11.9 cm/s in right and left MCA; p>0.05; 67.3+/-12.2, -45.3+/-7.6 cm/s in dominant MCA and BA). CVR did not differ between the dominant MCA and the BA (46.1+/-12.1, 46.0+/-15.1%; p>0.05), nor between the right and left MCAs (46.9+/-15.2, 46.4+/-14.8%; p>0.05). There was a positive linear correlation between the CVR of the dominant MCA and that of the BA (r=0.856; p<0.001). CONCLUSIONS: PMD with a probes fixating device for accurate insonation is a useful tool for evaluating the relative CVR between the MCA and BA. Our study suggests that CVR values of the BA are similar to those of the MCA.

Glossopharyngeal neuralgia (GPN) is a rare condition characterized by paroxysms of lancinating pain in the regions of the tonsil, ear, larynx and tongue. The pain is typically triggered by activities such as swallowing, speaking or coughing. Fifty-seven years old female patient had suffered paroxysms of severe pain in the unilateral region of the glossopharyngeal innervation for several years, and long term drug therapy result in serious pancytopenia probably due to carbamazepine. The patient with idiopathic glossopharyngeal neuralgia received glossopharyngeal nerve block and her symptoms were relieved completely. Glossopharyngeal nerve block with alcohol was done by extraoral approach and satisfactory results were obtained.

The purpose of this study was to compare the sealing abilities of four endodontic temporary restorative materials using a methylene blue dye penetration test under dynamic loading. Standardized access cavities were prepared in forty-four intact human permanent molar teeth, and the cavities were restored with Caviton, MD-Temp, IRM, or ZOE. After thermocycling, an intermittent load of 98 N at 1 Hz was applied for 1,000 cycles to the long axis of the functional cusp of each of the teeth, which were immersed in a 1% methylene blue solution. The teeth were split in half, and the linear depth of dye penetration was evaluated according to the criteria. The results were analyzed using one-way ANOVA (p = 0.05) and Duncan's multiple range test. The results demonstrated that Caviton and MD-Temp showed significantly lower microleakage than IRM and ZOE. It was concluded that Caviton and MD-Temp exhibited better sealing ability than IRM and ZOE under dynamic loading.

OBJECTIVES: To introduce a new injection material for vocal fold diseases, which could be readily translated to clinical practice, we investigated the effectiveness of platelet-rich plasma (PRP) injection on the injured vocal fold in terms of histological recovery. METHODS: Blood samples were drawn from New Zealand White rabbits and PRP was isolated through centrifugation and separation of the samples. Using a CO2 laser, we made a linear wound in the 24 vocal fold sides of 12 rabbits and injected each wound with PRP on one vocal fold side and normal saline (NS) on the other. Morphologic analyses were conducted at 2, 4, and 12 weeks after injection, and inflammatory response, collagen deposit, and changes in growth factors were assessed using H&E and masson trichrome (MT) staining and western blot assay. RESULTS: PRP was prepared in approximately 40 minutes. The mean platelet concentration was 1,315,000 platelets/mm3. In morphological analyses, decreased granulation was observed in the PRP-injected vocal folds (P<0.05). However, the irregular surface and atrophic change were not difference. Histological findings revealed significant inflammation and collagen deposition in NS-injected vocal folds, whereas the PRP-injected vocal folds exhibited less (P<0.05). However, the inflammatory reaction and fibrosis were not difference. In western blot assay, increased amounts of growth factors were observed in PRP-injected vocal folds. CONCLUSION: Injection of injured rabbit vocal folds with PRP led to improved wound healing and fewer signs of scarring as demonstrated by decreased inflammation and collagen deposition. The increased vocal fold regeneration may be due to the growth factors associated with PRP.

Kawasaki diseases occur frequently in children beyond the age of 4 years, but classic Kawasaki disease in newborns are rare and have not been reported in Korea yet. We report a case of classic Kawasaki disease in neonate who is 21 days old girl and has no response to gamma-globulin although early diagnosis and treatment. Her clinical features met typical Kawasaki disease, but unusually she had a non suppurative labia major erythema and severe edema instead of cervical lymphadenitis. She had persistent fever and progressive carditis with coronary dilatation in spite of 3 doses of gamma globulin. Her fever was subsided after 3 doses of intravenous methyl prednisolone. In the subacute stage her other symptoms subsided and appeared typical desquamation of fingers and toe. Finally she had mild mitral regurgitation and diffuse coronary dilatation when she was discharged. Since one year follow up, with continuous aspirin medication, now she is very healthy, and her coronary dilatation was normalized and not any more valvular regurgitation.

PURPOSE: Blood cultures are commonly performed in evaluation of febrile children without an obvious source of infection. Pediatric clinicians treat patients with a positive blood culture before final identification of the organism. This study sought to determine the yield and the clinical usefulness of blood cultures in pediatric patients younger than 3 years with fever at the emergency department. METHODS: We conducted a retrospective review of all children between the ages of 1 and 36 months with a body temperature of at least 38.0degrees C who underwent blood culture in the emergency department (ED) from January 2008 to December 2010. RESULTS: Bacteria growth occurred in 126(10.3%) out of 1,219 blood cultures. True positives (TPs), defined as true pathogens, were observed in 2.5% of cultures, representing 23.8% of positives. False positives (FPs), defined as contaminants, were observed in 7.9% of cultures, representing 76.2% of positives. Patients with TP cultures had lower mean pH (7.36+/-0.17 vs 7.41+/-0.08, p=0.031), higher mean base deficit (4.9+/-6.0 mmol/L vs 2.9+/-2.5 mmol/L, p=0.012), and higher mean C-reactive protein (CRP) level (3.3+/-3.7 mg/dL vs 1.8+/-3.2 mg/dL, p=0.034) than those with FP cultures. CONCLUSION: True positive results were observed relatively infrequently in blood cultures of febrile children younger than 3 years in the ED; therefore, changes in treatment of pediatric patients with fever are uncommon. However, bacteria identified by blood cultures are likely to be the true pathogen in a pediatric patient with a large base deficit or a high CRP level.

Fitz-Hugh-Curtis syndrome means perihepatitis consisting of liver capsule inflammation without parenchymal damage associated with pelvic inflammatory disease (PID). The incidence of this syndrome in PID is reported to be 15-30%. It produces right upper quadrant pain from acute inflammatory reaction between liver capsule and adjacent peritoneum in acute phase, and later forms characteristic violin-string adhesions. Recently, it is suggested that marked hepatic subcapsular enhancement at arterial phase in contrast-enhanced CT has diagnostic value, but diagnostic laparoscopy is used as definitive diagnostic method in Fitz-Hugh-Curtis syndrome. We have experienced one case of Fitz-Hugh-Curtis syndrome in women with right upper quadrant pain, which was diagnosed by CT imaging and was not improved by appropriate antibiotic therapy. In diagnostic laparoscopic examination, we have found direct adhesion between liver capsule and anterior abdominal wall and experienced improvement in symptoms after adhesiolysis. So, we report this case with the brief review of the literatures.
