Granular Cell Tumors(GCT) were originally described as myoblastic myomas. Subsequent scientific investigations elucidated the origin of this tumor as Schwann cells . Usually they have a predilection for head and neck, but also can occur in many other organs. This tumor is believed to originate from Schwann cells based on subsequent scientific investigations. Although it usually appears in the head and neck, it can also appear in other organs, as well. Endobronchial granular cell tumors are rather rare and should be differentiated from other common diseases of endobronchial location endobronchial diseases such as bronchogenic carcinoma and endobronchial tuberculosis, especially in Korea . We report a A case of a patient with an extremely rare condition of endobronchial granular cell tumor concurrent with malignant mediastinal tumor in a patient (delete) is reported.

Myotonic dystrophy is a multisystemic disorder inherited as an autosomal dominant trait. The characteristic clinical features include the presence of myotonia, atrophy of the muscles of the face and the sternocleidomastoids and numerous nonmusclar manifestations such as cataracts, frontal baldness, gonadal dysfunctions and cardiac abnormalities. We experienced one case of myotonic dystrophy with prolonged atrial flutter in 30-year-old male who was admitted because of palpitation. We present this case with reviewing literatures.

The author performed this study to investige the relationship between condylar movements recorded with Pantronic and mandibular movements at incisal area recorded with BioEGN. For this study 24 patients with Temporomandibular disorders (TMDs) and 30 dental students without any masticatory symptoms were selected as patients group and control group, respectively. The items recorded with Pantronic(Denar Corp., USA) were immediate side-shift, orbiting path, protrusive path, and PRI. BioEGN(Bioelectric-gnathography, Bioresearch Inc., USA) were sued to measure the amount of mandibular torque movement in frontal and horizontal plane and also the distance of mandibular translation at incisal area. Amount of mandibular rotational torque movement was analyzed by angle and difference between both condyles in frontal and horizontal plane. The collected data were processed with SAS program and conclusion were as follows : 1. Mean value of items recorded with Pantronic were not significantly differed between patients group and control group except the item of pantographic reproducibility index(PRI). The value of PRI was 39.5 in patients group, and 29.5 in control group. 2. The amount of mandibular torque movement was not differed tin early protrusive and early left excursion between patients group and control group, but in early right excursion, patients group showed more value than control group did. 3. The distance on sagittal plane in early eccentric movements were longer in patients group than those in control group, but the distance of maximal eccentric movements were not significantly differed between patients group and control group. 4. Items which showed significant correlation with PRI were progressive side-shift, and horizontal torque movement in early protrusion and right excursion. 5. The angle of protrusive path of affected side was greater than of non-affected side in unilaterally affected patients, but the protrusive angle of preferred chewing side was not differed from that of contralateral side in control group. 6. The amount of torque movement in early protrusion and right excursion were greater in patients with coincidence of affected side and preferred chewing side than in patients without coincidence.

Incidence of adenocarcinoma of the kidney in long-term hemodialysis is higher than in the general group. Although renal cancers occuring in dialysis patients are often small and asymptomatic, some patients present with cutaneous, visceral, or skeletal metastasis. We report a case of adenocarcinoma of the kidney in chronic hemodialysis patient. A 36-year-old male was diagnosed as chronic renal failure 6 years ago and then had been recieving hemodialysis. Renal tumor and multiple renal cysts were incidentally found in right kidney by renal ultrasonography and abdominal CT scanning. Radical nephrectomy was done and pathologic diagnosis was renal cell carcinoma and multiple simple renal cysts.

Mitral ring motion and indices of left ventricular diastolic filling were measured by M-mode and Doppler echocardiography in apical 4 chamber view in 11 dilated cardiomyopathy patients and 9 normal subjects without clinical evidence of heart disease. The mean age of patients was 52 years and average heart rate was 76 beats/min. The parameters of mitral annulus motion include earley relaxation amplitude(ER), late atrial contraction amplitude(AC) and A2-peak excursion(A2-PE). Transmitral flow velocity parameters include peak flow velocity of early diastolic flow velocity(PFVE), peak flow velocity of late atrial contraction(PFVA), the ratio between early and late peak flow velocity(PFVE/PFVA), Acceleration rate of early diastolic peak flow(AR), deceleration rate of early diastolic peak flow(DR), time velocity integral of early diastolic flow velocity(TVIE), time velocity integral of late atrial contraction flow velocity(TVIA) and ratio between early diastolic and late atrial flow velocity integral(TVIE/TVIA). In patients with dilated cardiomyopathy, ER(4.5+/-2.3mm) and AC(2.3+/-1.6mm) were significantly decreased than normal(10.7+/-2.6mm, 6.6+/-1.6mm, p<0.01, p<0.01, respectively), whereas ER/AC(1.7+/-0.7) was not significantly different than normal subjects(1.6+/-0.5). A2-PE(100+/-80 msec) was significantly delayed in dilated cardiomyopathy patients than normal subjects(35+/-25 msec, p<0.01). In analysis of transmitral flow velocities, PFVE, PFVA and PFVE/PFVA, etc were not significantly different compared to normal subjects in patients with dilated cardiomyopathy. Mitral ring motion amplitude was decreased and A2-peak excursion time interval(A2-PE) was delayed in patients with dilated cardiomyopathy, but transmitral flow velocities were not significantly different from normal subjects in patients with dilated cardiomyopathy. These results reflect the facts that early diastolic relaxation amplitude is decreased by the change of compliance of LV and late atrial contractin amplitude is decreased by decrease of atrial contractility and increased stiffness of LA and LV. Despite of decreased mitral ring motion, transmitral flow velocity is not significantly different compared to normal subjects in patients with dilated cardiomyopathy. From these evidences, not only transmitral flow velocity affected by multiple factors but also mitral ring motion affected by LA and LV function are considered in assessment of LV diastolic dysfuction.

PURPOSE: Return of spontaneous circulation (ROSC) is closely related to a favorable treatment outcome in out-of-hospital cardiac arrest and is also a reliable treatment target in clinical trials. The aim of this study is the identification of major factors affecting field ROSC by analyzing the updated data encompassing the pre-hospital treatment processes. METHODS: This is a retrospective review of cardiopulmonary resuscitation (CPR) cases performed by 119 rescuers before hospital arrival from January 2012 to December 2014 in one province. Cases with traumatic cardiac arrest, unnecessary CPR, arrest occurred during transport, under age 14 years, and incomplete medical records were excluded. RESULTS: Of 1,832 patients enrolled in the study, ROSC was achieved in 99 cases (5.4%). Among them, 50 (50.5%) had ROSC at the event field and others achieved ROSC during the transport process, respectively. Total cases were divided into two groups based on ROSC before arrival at the hospital. Age, underlying cardiovascular illnesses, the event place, presence of a witness, bystander CPR, application of an automated external defibrillator (AED), the initial shockable rhythm, defibrillation, advanced airway, hydration, the arrival time of rescuer CPR, application time of AED, and defibrillation showed significant statistical differences.

In multivariate analysis, age, defibrillation, hydration, bystander CPR, and the call-to-rescuer CPR interval appeared to be correlated with field ROSC. CONCLUSION: To improve the survival rate through field ROSC, a public campaign to improve bystander CPR, prompt recognition of cardiac arrest, and rapid application of pre-hospital treatment and political support of the public institution are mandatory.

PURPOSE: To report three various cases of retinal hemorrhages caused by Plasmodium vivax malaria. CASE SUMMARY: Two 55-year-old male patients and a 52-year-old male patient with cyclic high fever were admitted to the department of internal medicine. Three of the patients were diagnosed with malaria caused by P. vivax based on a peripheral blood smear. The patients were treated with hydroxychloroquine and premaquine but complained of decreased visual acuity. The patients were examined with funduscopy, fluorescein angiography, and optical coherence tomography. The first case showed 2 areas of retinal hemorrhages on the macular in the right eye and 1 area of retinal hemorrhage in the left eye. The second case showed many cotton-wool spots along with a number of small retinal hemorrhages and tortuous blood vessels in both eyes. The third case showed 1 area of retinal hemorrhage in the right eye and many cotton-wool spots in both eyes. CONCLUSIONS: P. vivax malaria rarely causes retinal hemorrhage. Manifestations of retinal hemorrhage and degree of visual acuity loss may vary among patients. P. vivax malaria should be considered when patients with unexplained high fever present with retinal hemorrhage, even without a history of overseas travel.

OBJECTIVES: To evaluate the effects of sperm motility stimulants on the hyperactivation (HA), acrosomal reaction (AR) and sperm penetration assay (SPA) in fresh and frozen-thawed spermatozoa from fertile men. METHODS: We treated the semen samples obtained from 20 normospermic men (fresh semens from 10 and cryopreserved ones from 10) with pentoxiphylline (PF) and 2-deoxyadenosine (2-DXA) to evaluate the change of the patterns of motility using the computerized motility analyzer. The semen samples treated with motility stimulants were incubated in the medium with calcium ionophore A23187 for the examination of the proportion of acrosome lost spermatozoa. Finally we performed SPA in both groups for the evaluation of fertilizing capacity after stimulant treatments. RESULTS: In both fresh and cryopreserved semen samples, the addition of PF and 2-DXA significantly altered the patterns of motility (ALH, VCL, HA) known to have association with sperm quality without increasing the number of sperms with progressive motility and velocity. A23187 induced AR was also augmented by the treatment with PF and 2-DZA. Although the treatment with PF did not increase the mean rates of egg penetration significantly, in selected cases in the cryopreserved semen group, the improvement of the motility pattern was impressive. CONCLUSION: PF and 2-DXA can improve the quality of sperm function in both fresh and frozen-thawed semen from normal fertile men and may increase the sperm penetration rate of zona-free hamster eggs in selected samples of the frozen-thawed semen. The results suggest that PF and 2-DXA pretreatment can be used in the clinical practice for intrauterine insemination (IUI) program with frozen-thawed sperms as well as with samples from men with abnormal semen parameters. In addition, it may be a cost- effective therapy to try IUI combined with such a pretreatment for the couples planned to enter into the ART program.

PURPOSE: The hepatolithiasis and associated cholangitis result in liver atropy, biliary stricture, liver abscess and intrahepatic malignancy, and a hepatic resection should be performed in such cases. The technical difficulty and accompanied inflammation with a hepatic resection frequently cause postoperative complications. Therefore, the factors affecting the postoperative complications were evaluated. METHODS: Twenty one patients, with hepatolithiasis that had received a hepatectomy at the Department of Surgery, Eulji University Hospital between March 2001 and January 2003, were reviewed. RESULTS: The postoperative complications were intraabdominal abscess (7 cases), pleural effusion (3 cases), wound complication (3 cases), T-tube site leakage (1 case), cardiac arrest (1 case), acute pancreatitis (1 case), hepatitis A (1 case) and delayed gastric emptying (1 case). The overall complication rate was 57% (12/21 patients) and the most common complication was an intraabdominal abscess (7 cases). The factors that may affect these complications were analyzed. Preoperative percutaneous transhepatic biliary drainage (PTBD) increased the postoperative complications, which was statistically significant (p=0.027). Especially, preoperative PTBD and hepaticojejunostomy increased the rate of an intraabdominal abscess, which was statistically significant (p=0.026, p=0.008). CONCLUSION: With hepatolithiasis requiring hepatic resection there is a need to avoid unnecessary preoperative PTBD and bypass surgery for the reduction of postoperative complications, including an intraabdominal abscess. Conversely, it is considered important to remove every stone and avoid needless bypass surgery under an operation and for a hepatic resection to be performed after removing PTBD, where possible.

Gradual decline in cognitive function and behavioral changes are characteristic in degenerative dementia. Although acute to subacute subcortical lesion can affect behavior and cognition, few reports have described both cognitive and behavioral deficits in patients with right basal ganglia lesion. An 82-year-old man presented with memory impairment, pathological crying, delusion and other psychological symptoms that developed insidiously over the previous 2 months. Initially, the patient had been diagnosed with degenerative dementia, but brain MRI showed the hematoma in the right basal ganglia. Our case shows that cognitive dysfunction, behavioral and psychological symptoms including pathological laughing and delusion can be developed concurrently by the lesion of the right basal ganglia. Our case suggests that cerebrovascular disease should be considered in elderly patients presenting with subacute cognitive and behavioral deterioration, even when there were no other neurological signs.
