Eight patients with polycythemia vera were diagnosed from 1965 through 1977 among the patients of Seoul National University Hospital. In our series there were 4 men and 4 women with average age of 54 years at the time of diagnosis. Symptoms of facial plethora, headache, pruritus and dizziness were the most frequent manifestations of disease in order of frequency. At inital examination 8 of 8 patients had facial plethora, 6 of 8 patients splenomegaly and 4 if 8 patients hepatomegaly. The laboratory data revealed mean Red cell volume of 55+10ml/kg which was elevated in all cases. Leukocytosis was observed in 5 of 8 patients and thrombocytosis 2 of 8 patients. Leukocyte alkaline phosphatase was increased in all cases. Bone marrow aspiration disclosed typical panmyelosis in 5 of 8 patients. In one patient there was diffuse myelofibrosis on bone marrow biopsy. The combined diseases included 2 patient with hypertension and 1 patient with thrombosis of aorta and left renal artery. The patients were treated with phlebotomy alone in 2 patients, chemotherapy with busulfan in 1 patient and $^{32}P$ in 5 patients with favorable results. During the mean 29.9 months follow up period, there were development of iron deficiency in 3 patients, hyperuricemia in 2 patients and thrombosis in 1 patient. The occurrence of acute leukemia of myelofibrosis was not observed in the course of disease.

Objective : The purpose of this study was to identify independent predictors of mortality and functional recovery in patients with primary intracerebral hemorrhage (PICH) and to improve functional outcome in these patients. Methods : Data were collected retrospectively on 585 patients with supratentorial PICH admitted to the Stroke Unit at our hospital between 1st January 2004 and the 31st July 2008. Using multivariate logistic regression analysis, the associations between all selected variables and 30-day mortality and 90-day functional recoveries after PICH was evaluated. Results : Ninety-day functional recovery was achieved in 29.1% of the 585 patients and 30-day mortality in 15.9%. Age (OR=7.384, p=0.000), limb weakness (OR=6.927, p=0.000), and hematoma volume (OR=5.293, p=0.000) were found to be powerful predictors of 90-day functional recovery. Furthermore, initial consciousness (OR=3.013, p=0.014) hematoma location (lobar, OR=2.653, p=0.003), ventricular extension of blood (OR=2.077, p=0.013), leukocytosis (OR=2.048, p=0.008), alcohol intake (drinker, OR=1.927, p=0.023), and increased serum aminotransferase (OR=1.892, p=0.035) were found to be independent predictors of 90-day functional recovery after PICH. On the other hand, a pupillary abnormality (OR=4.532, p=0.000) and initial unconsciousness (OR=3.362, p=0.000) were found to be independent predictors of 30-day mortality after PICH. Conclusion : The predictors of mortality and functional recovery after PICH identified during this analysis may assist during clinical decision-making, when advising patients or family members about the prognosis of PICH and when planning intervention trials.

Objectives: Although Campylobacter is the main cause for bacterial acute gastroenteritis (AGE), there has been no notable clinical research into it, especially for Korean children. In this study, we share our experience of clinical, laboratory and image findings with Campylobacter AGE. Methods: Between May 2013 and June 2016, children diagnosed as having Campylobacter AGE were retrospectively enrolled in our study. Campylobacter AGE was considered diagnosed when a patient had symptoms of bacterial AGE and a positive Campylobacter result in stool using multiplex PCR. Results: Among 539 patients with suspected bacterial AGE, 31 (5.8%) patients had a positive result for Campylobacter. The average age of the 31 patients was $10.2{\pm}5.0$ years with a range between 1.1 and 16.9 years. Eighteen (58%) of the total patients were hospitalized between June and August. Diarrhea (93.5%), abdominal pain (83%) and fever (83%) were common symptoms. For 20 patients (65%), diarrhea lasted for less than three days, and fever lasted for 2.1 days on average. Among the 20 patients subjected to imaging studies, 12 patients (60%) showed bowel wall thickening on the right side of colon. In blood tests of 30 patients, 22 (73%) and 29 (97%) patients exhibited leukocytosis and elevated C-reactive protein, respectively. During treatment for Campylobacter AGE, prediagnostic empirical antibiotics were used for 6 (19%) patients. All patients recovered without complications. Conclusions: Among the children with suspected bacterial AGE, 5.8% had a positive result on Campylobacter in stool using multiplex PCR. Therefore, we observe that Campylobacter AGE should be considered in school-age children who have diarrhea, fever, and abdominal pain.

A 2-year-old intact female Maltese dog was presented with generalized involuntary tremors and nystagmus without regular direction. The dog was conscious the whole time while it was trembling. Its involuntary tremors were alleviated at rest or during sleep. Magnetic resonance imaging (MRI) revealed asymmetric hydrocephalus and caudal occipital malformation. In cerebrospinal fluid (CSF) analysis, a trace of protein was found and total nucleated cell count (TNCC) was slightly increased. However, infectious pathogens were not found. In complete blood count, there was a mild leukocytosis. After the patient received anticonvulsants (midazolam, phenobarbital, KBr), diuretics (furosemide) with an anti-inflammatory drug (prednisolone, 0.5 mg/kg PO bid), and a proton-pump inhibitor (omeprazole), it showed no improvement. The patient was tentatively diagnosed with corticosteroid responsive tremor syndrome. So the anticonvulsants and diuretics were discontinued and the dose of prednisolone was increased to an immunosuppressive dose (1 mg/kg PO bid). After administering the immunosuppressive dose of prednisolone, the patient did not show nystagmus. Its tremors were much alleviated. However, they did not disappear. Five weeks later, the patient showed gradual improvement but still was trembling when moving around. Nine weeks later, its tremors were similar to before. So diazepam (0.3 mg/kg PO sid) was added to the treatment. After that, its tremors were alleviated more. Prednisolone and diazepam were maintained for about five months, with tapering of the dose of prednisolone (until 0.5 mg/kg PO sid). About 7 months later after the treatment was started, the dog was trembling rarely except when it was excited. Therefore, diazepam was discontinued. This case describes a refractory white dog shaker syndrome successfully managed with long-term administration of a steroid and diazepam.

Purpose: Despite previous studies reporting the development of rhabdomyolysis (RM), this affliction tends to be neglected as an envenomation sign in South Korea. The current retrospective study investigates the prevalence and prognosis of RM after a snakebite. We further searched for predictors of snakebite-induced RM, which can be observed at presentation. Methods: This study included 231 patients who presented to the ED within 24 hours after a snakebite. The patients were classified according to the severity of RM, and the data, comprising baseline characteristics and clinical course including the level of creatine kinase (CK), were collected and compared according to the severity of RM. Results: The prevalence of RM and severe RM were determined to be 39% and 18.5%, respectively. Compared to the group without RM or with mild RM, the group with severe RM had a higher grade of local swelling, a higher frequency of acute kidney injury and neurotoxicity, and a greater need for renal replacement therapy and vasopressor administration. However, the incidence of acute renal injury in the RM group was 7.7%, with two patients needing renal replacement therapy. No mortalities were reported at discharge. Results of the multinomial logistic regression model revealed that the WBC levels are significantly associated with the risk of severe RM. Conclusion: RM should be considered the primary clinical sign of snake envenomation in South Korea, although it does not seem to worsen the clinical course. In particular, physicians should pay attention to patients who present with leukocytosis after a snakebite, which indicates the risk of developing RM, regardless of the CK level at presentation.

A 3-year-old, 20.6 kg, neutered male German Shepherd dog was referred to Kyungpook National University Veterinary Medicine Teaching Hospital. Clinical examination revealed chronic diarrhea for 6 weeks and a non-tender, distended abdomen without lethargy, anorexia, and vomiting. Diarrhea was watery and had a waxing and waning course despite symptomatic treatment. A complete blood count identified mild leukocytosis and mild anemia. Serum biochemistry analysis showed elevated alanine aminotransferase and aspartate aminotransferase levels, and mild hypoalbuminemia. Abdominal ultrasound examination revealed mixed echogenicity with absent blood flow at the caudate process of the caudate liver lobe and a small amount of ascites. Computed tomography revealed torsion of the caudate process of the caudate liver lobe and spleen and gas dilatation of the intestine. After establishing a diagnosis of organ torsion on imaging, we deemed the condition an emergency and immediately performed surgery. Given that laparotomy confirmed organ torsion, liver lobectomy, total splenectomy, and prophylactic gastropexy were conducted. The patient was discharged 11 days after surgery without complications. In general, liver lobe torsion and splenic torsion are uncommon in dogs and present with nonspecific clinical signs, such as abdominal pain, lethargy, anorexia, and vomiting. In the current case, torsion of the caudate liver lobe and spleen occurred without other clinical signs except for a distended abdomen. Moreover, no reports in dogs have demonstrated the simultaneous occurrence of both diseases.

Objective: This study aimed to evaluate the clinical benefits and risks of CT-guided percutaneous transthoracic needle lung biopsies (PTNBs) in patients with a suspected pulmonary infection. Materials and Methods: This study included 351 CT-guided PTNBs performed in 342 patients (mean age, 58.9 years [range, 17-91 years]) with suspected pulmonary infection from January 2010 to December 2016. The proportion of biopsies that revealed the causative organism for pulmonary infection and that influenced patient's treatment were measured. Multivariate analyses were performed to identify factors associated with PTNB that revealed the causative organism or affected the treatment. Finally, the complication rate was measured. Results: CT-guided PTNB revealed the causative organism in 32.5% of biopsies (114/351). The presence of necrotic components in the lesion (odds ratio [OR], 1.7; 95% confidence interval [CI], 1.1-2.7; p = 0.028), suspected pulmonary tuberculosis (OR, 2.0; 95% CI, 1.2-3.5; p = 0.010), and fine needle aspiration (OR, 2.5; 95% CI, 1.1-5.8; p = 0.037) were factors associated with biopsies that revealed the causative organism. PTNB influenced patient's treatment in 40.7% (143/351) of biopsies. The absence of leukocytosis (OR, 1.9; 95% CI, 1.0-3.7; p = 0.049), presence of a necrotic component in the lesion (OR, 2.4; 95% CI, 1.5-3.8; p < 0.001), and suspected tuberculosis (OR, 1.7; 95% CI, 1.0-2.8; p = 0.040) were factors associated with biopsies that influenced the treatment. The overall complication rate of PTNB was 19% (65/351). Conclusion: In patients with suspected pulmonary infection, approximately 30-40% of CT-guided PTNBs revealed the causative organism or affected the treatment. The complication rate of PTNB for suspected pulmonary infection was relatively low.

목 적: EBV 감염 질환은 발생 연령별로 임상 소견이 다양하며 혈청검사 소견이 상이하다. EBV 감염을 진단하기 위하여 혈청학적 검사가 주로 이용되어왔는데, 근래에는 EBV 항원을 검사하는 검사법이 활발하게 이용되고 있다. 이에, 임상 소견이 EBV 감염과 관련된 질환을 시사하는 환자의 혈액에서 중합효소 연쇄반응 검사로 EBV 감염을 확인고, 혈청검사 결과와 비교하여 EBV 감염 질환의 임상 특성을 알아보고자 하였다. 방 법: 2004년 1월부터 2006년 12월까지 EBV 감염을 의심할 수 있었던 352명을 대상으로 EBV PCR을 시행하여 115명에서 양성의 결과를 얻었으며 이들 환자에서 EBV-IgM Ab 검사를 시행하였다. 백혈구, 혈소판, 비정형 백혈구, AST, ALT 등을 검사 하고 이들 임상소견과 검사소견을 EBV-IgM Ab 검사 음성인 예와 양성인 예를 비교하였다. 주요 검사 소견은 전예에서 생후 3세 미만, 3-5세, 6-9세, 10-15세의 4연령군으로 나누어 비교 평가 하였다. 결 과: EBV PCR에서 유전자가 검출된 115예에서 8세 이하의 어린이가 대부분 이었고(89%), 남녀 비는 1.3:1이었다. 115전예에서 인두염과 $37.5^{\circ}C$ 이상의 발열이 있었다. 경부 림프절 비대는 39예(34%), 복통을 포함한 복부 이상 20예(17%)의 순으로 관찰되이었다. EBV-IgM Ab는 33예(29%)에서 양성이었다. 말초혈에서 백혈구증가($WBC{\geq}10,000/mm^3$)는 54예(47%)에서 관찰되었고 비정형림프구(${\geq}20%$)는 28예(24%)에서 관찰되었다. 5세 이하에서 6세 이상의 연령군에 비해 ALT가 높았으며 EBV IgM Ab가 양성인 예가 많았다. 결 론: EBV 유전자를 PCR로 검사하여 발견한 연령별 본포의 누적 예는 8세에 이르기까지 급격하게 증가하였으며 EBV-IgM Ab가 양성인 환자에서 감염 단핵구증의 특징적인 소견을 보이는 예가 많았다. EBV 관련 감염질환 환자 가운데 연령이 어릴수록 ALT가 높고 EBV-IgM Ab의 발현이 많았으나 이 외의 임상 및 검사 소견은 차이가 없었다.
