Posterior nutcracker phenomenon (PNP) was found to be the cause of significant proteinuria in a 10-year-old female. PNP was documented by Doppler ultrasonography and abdominal 3D CT as a cause of her proteinuria. Despite treatment with ACE inhibitor for several months, her persistent and progressive proteinuria lead us to perform a left renal biopsy, which revealed no significant finding except for focal effacement of foot processes. We speculate that nutcracker phenomenon can induce not only orthostatic proteinuria but also significant proteinuria by focal effacement of foot processes.

Patients with moderate to severe degrees of Henoch-Schonlein purpura (HSP) nephritis receive high-dose intravenous methylprednisolone pulse therapy (IMPT). Although the regimen is generally safe and effective, various complications occasionally develop. administration of excessive corticosteroid can induce urinary potassium wasting leading to hypokalemia. Polyuria, one of the complications of hypokalemia, is related to both increased thirst and mild nephrogenic diabetes insipidus. And hypokalemia itself also impairs the maximal renal urinary concentration ability. Although polyuria or nocturia after IMPT is not common, it is correctable immediately by oral potassium supplementation. Therefore, during IMPT, careful history taking of nocturia as well as monitoring urine volume, serum and urine potassium level at regular follow-up are necessary because even mild hypokalemia can provoke urine concentrating ability defect. We experienced a case of 11 year-old boy with HSP nephritis who suffered from hypokalemia-induced polyuria with nocturia right after IMPT.

PURPOSE: The aim of this study was to evaluate the incidence of febrile urinary tract infection (UTI) according to clinical characteristics in patients with congenital hydronephrosis (CH) and hydronephrotic patients first diagnosed with hydronephrosis during treatment of febrile UTII. METHODS: In this study, 200 patients with congenital hydronephrosis were enrolled in group 1 and 252 patients first diagnosed with hydronephrosis during treatment of febrile UTI were enrolled in group 2. We counted the episodes of UTI in the two groups according to clinical characteristics, the presence of VUR, type of feeding, and clinical outcomes since 2000. And we compared those results between the two groups. and compared two groups as well. RESULTS: The incidence of recurrent UTI was 10%, 0.028 per person-year in group 1 and 16.7%, 0.051 per person-year in group 2, respectively (P <0.05). Group 2 had more VUR (3% vs. 27%, P <0.05) and higher incidence of UTI than group 1. The incidence of UTI in patients with CH of Society of Fetal Urology (SFU) grade 4 or grade 4-5 VUR was 80% and 44.4%, respectively. No significant differences were found in incidence of UTI between BMF (breast milk feeding) and artificial milk feeding group in both groups (P 1= 0.274, P 2=0.4). The time of resolution of CH had no correlation with either number of UTI episodes or the presence of VUR. CONCLUSION: The overall incidence of UTI is low in patients with CH as well as patients patients first diagnosed with hydronephrosis during treatment of febrile UTI except patients with SFU grade 4 or grade 4-5 VUR. BMF has no protective effect against UTI.

BACKGROUND AND OBJECTIVES: Burning mouth syndrome (BMS) refers to a collection of symptoms of patients who complain about burning sensation of their mouths without any specific causes. Although this is not a rare disease, the etiology and effective treatment are not well established. We tried to compare the efficacy and side effects of the agents that are reported to be relatively effective to BMS. SUBJECTS AND METHOD: Fifty-one patients who were diagnosed as BMS were chosen as candidates. Trazodone, Paroxetine, Clonazepam, and Gabapentin, which were known to be effective medicines for BMS in previous research were prescribed randomly. We prescribed medication for two weeks and evaluated patients for the effect and side effects at the end of the treatment. The medication was prescribed for 2 more weeks and the patients were evaluated again. RESULTS: Three of 11 (27.3%) patients were prescribed Trazodone, 8 of 12 (66.7%) Paroxetine, 8 of 14 (57.1%) Clonazepam and 12 of 14 (85.7%) Gabapentin. Q showed improvements after 4 weeks of medication. The differential effectiveness among the medications was not significant, except for the inferiority of Trazodone. Five of 11 (45.5%) patients who had been prescribed Trazodone, 2 of 12 (16.7%) who had been prescribed Paroxetine, 2 of 14 (14.3%) who had been prescribed Clonazepam, 2 of 14 (14.3%) who had been prescribed Gabapentin complained of side effects during 4 weeks of medication. CONCLUSION: We can expect high success rates of treatment for burning mouth syndrome with Paroxetine, Clonazepam and Gabapentin. A further study for long term outcomes and side effects in large groups is warranted.

Deep vein thrombosis (DVT) is a serious illness sometimes causing death due to acute pulmonary thromboembolism (PTE). Blood stasis of the pelvic vein is a major etiologic factor for DVT. Occasionally a huge uterine myoma can cause compression of the pelvic venous system leading to DVT. We experienced a very rare case of pulmonary thromboembolism in a 45-year-old woman with a huge uterine myoma and no other recognized risk factors for PTE and DVT. The patient was successfully treated with thrombolytic and anticoagulation therapy associated with total hysterectomy.

We present a case of an endometrial cancer patient with germline mutation in MutS homolog 6 (MSH6), associated with Lynch syndrome. A 60-year-old Korean woman had a personal history of colon cancer 23 years ago. She also had a family history of endometrial cancer and colon cancer of her sisters and brothers. Immunohistochemistry was negative for MutL homolog 1 (MLH1) and positive for MutS homolog 2 (MSH2). Based on these findings, she underwent genetic counseling and testing that revealed a frameshift germline mutation at MSH6 (c. 3261dupC).

BACKGROUND AND OBJECTIVES: Postnasal drip is a common presentation to the medical practitioner. It is a result of disturbance to the normal drainage or an increase in secretion of the paranasal sinuses. However, sometimes no underlying cause can be found and the patient has to be reassured, and that they may just have to live with it. The aim of this study is to evaluate the clinical manifestations of patients with postnasal drip. MATERIAL AND METHOD: There were 90 patients complaining with postnasal drip. We performed a prospective study about accompanying symptoms and physical and psychiatric evaluation. CONCLUSION: Postnasal drip is more common in females over 30 years and the duration of symptoms is usually long. Anatomical nasal abnormality and sinusitis are common. There is no correlation with postnasal drip and psychiatric problems. But several items are concerned with postnasal drip. So we need detailed history taking and physical examination on patients who complained of postnasal drip.

BACKGROUND: Plasmid-mediated AmpC beta-lactamases (PABLs) have been detected in the strains of Escherichia coli, Klebsiella spp., Proteus mirabilis, and Salmonella spp. PABLs may be difficult to detect and might interfere in the therapeutic and infection-control processes. Although several PABL-detection methods based on phenotypes have been reported, the Clinical and Laboratory Standards Institute currently does not recommend a routine detection method for PABLs. The aim of this study is to compare the performances of 3 phenotypic PABL detection methods. METHODS: Total 276 non-duplicated clinical isolates of E. coli (N=97), K. pneumoniae (N=136), and P. mirabilis (N=43) were collected from 14 hospitals in Korea between April and June 2007 in a non-consecutive and non-random manner. Multiplex PCR was performed to detect the PABL genes. Further, 3 phenotypic detection methods-cephamycin-Hodge test, Tris-EDTA (TE) disk test, and combination-disk test with 3-aminophenylboronic acid (BA)-were performed using cefoxitin and cefotetan disks. RESULTS: PABL genes were detected by multiplex PCR in 122/276 isolates, including 14/97 E. coli, 105/136 K. pneumoniae, and 3/43 P. mirabilis isolates. The combination-disk test with BA showed higher sensitivity (98.4%), specificity (92.2%), and efficiency (96.3%) than the cephamycin-Hodge (76.2%, 96.1%, and 88.6%, respectively) and the TE-disk (80.3%, 91.6%, and 87.9%, respectively) tests. CONCLUSIONS: The combination-disk test with BA is a simple, efficient, and interpretable test that can be applicable in clinical laboratories involved in the detection of PABLs in clinical isolates of E. coli, K. pneumoniae, and P. mirabilis.

Twin-to-twin transfusion syndrome (TTTS) is one of the complications showing high mortality rate in monochorionic twins with vascular communication in the placenta. Clinical manifestations of TTTS are usually characterized by polyhydramnios, circulatory overload, cardiac failure and fetal hydrops in the recipient twin and symmetrical fetal growth restriction, oligohydramnios, hypovolemia and anemia in the donor twin. TTTS occurres in 10-35% of monochorionic twins. We report three cases of TTTS with fetal hydrops in which amnioreduction was serially attempted and maternal digoxin treatment was tried for the therapeutic purpose.

Fungal balls consist of rounded conglomerates of fungal mycelia, which can form within a preexisting cavity. They are mostly found in the paranasal sinuses in the head and neck regions. Cholesterol granuloma is a fibrotic lesion that develops as a tissue response to a foreign body such as cholesterol crystals or hemosiderin and is often associated with chronic otitis media. We present the unusual case of a 62-year-old male who was treated for chronic otitis media, which was histologically confirmed as a fungal ball and cholesterol granuloma in the middle ear cavity following tympanomastoidectomy. This is the first reported case of synchronous fungal ball and cholesterol granuloma in the middle ear cavity.
