Primary pulmonary hypertension is a rar, incurable, and progressive clinical entity. When associated with pregnancy, the prognosis of primary pulmonary hypertension is worsened with maternal mortality rates of at least 50%. The patient was a 29-year-old mother in her 2nd pregnancy, with previous uncomplicated gestation, 5 years ago. She had been well until the 28th week of present gestation when she was admitted because of increasing dyspnea on exertion. She was a housewife with no remarkable family and past histories. We have experienced a patient with primary pulmonary hypertension in pregnancy. She was treated with an oral calcium-channel blocker and low-molecular-weight heparin and was delivered vaginally with good maternal and fetal outcome. So we report a case of primary pulmonary hypertension associated with pregnancy and review literature.

Functional paraganglioma of the mediastinum is an uncommon tumor of the paraganglion system that causes symptoms and signs of episodic catecholamine release. It has not been reported in Korea. We experienced a case of a 17 years old man with a history of diaphoresis and paroxysmal hypertension refractory to therapy since 14 years old. Urinary execretion of catecholamine and its metabolites were elevated. Computed tomography(CT) scan revealed high density mass located on the posterior mediastinum in the area of the right fifth intercostal space. At thoracotomy, a 3X3X4cm sized lesion was resected and confirmed as a paraganglioma.

Purpose: A laparoscopic radical nephrectomy is known to cause less morbidity than a traditional open radical nephrectomy. In our institution, the laparoscopic approach, with intact specimen removal, has become the standard technique for radical nephrectomies. Herein, we report the results and oncological outcome of the experience of a single center. Materials and Methods: We reviewed 68 transperitoneal laparoscopic radical nephrectomies, performed for suspected renal cell carcinoma between December 1999 and June 2006. All data were collected from the patient's medical records. Results: The mean tumor size, surgical time and estimated blood loss were 4.82cm (1.7-14), 228.5 min (120-480) and 409.1cc (32-1,312), respectively. Conversion to open surgery was required in one case due to Endo-GIA malfunction, and conversion to hand-assisted surgery was performed in one case. The histological findings were pT1, pT2 and pT3 in 40 (59.7%), 9 (13.4%) and 18 patients (26.9%), respectively. In one case, the histology confirmed a non-malignant disease. The follow-up period was from 3 to 80 months (median 18). Distant metastasis was observed in 2 cases, but there was no local recurrence or port metastasis. Conclusions: A laparoscopic radical nephrectomy is a safe and feasible treatment for localized renal cell carcinomas. Longer follow-up and large scale studies are necessary to evaluate the long-term survival and disease- free rates, and confirm the effectiveness of performing a radical laparoscopic nephrectomy.

A nine-year old boy was found unconscious by his father in his apartment house. He was transferred to the emergency unit immediately but resuscitation was failed. Drain cleansing was performed just before the deceased came home. The father stated that there was foul odor in the house when he opened the door. The autopsy finding showed only nonspecific findings including severe pulmonary edema. Significant amount of sulfide ion was detected from blood and brain tissue. The cause of death was concluded as hydrogen sulfide poisoning.

A teenaged female was found dead in front of a three story building. Blunt force injuries were found mainly in the right upper-posterior part of the body. Autopsy findings revealed basal skull fracture, multiple rib fractures of the right thoracic cage, both scapular fractures and right iliac bone fracture. Additionally, typical so-called 'tramline'bruises were bilaterally noted at buttocks. The hymen was intact, but showed mucosal hemorrhage. After the personal identity was revealed, the police could find a witness who heard the detailed description of the criminal acts from one of the suspects. According to the witness, the deceased was pushed by two other teenaged girls from the concrete fence of the roof floor after the suspects molested the genitalia of the deceased and beat on the buttocks with a wooden stick. Mathematical estimation of the height of fall based on the severity of injuries correlates with that of the three story building. Authors suggest that a careful examination of injury patterns is required to differentiate homicidal falls from suicidal or accidental ones. Furthermore, application of mathematical model might be helpful to estimate the height of falls or correlate the assumed height of fall with severity of injuries.

PURPOSE: The aim of this study was to assess the usefulness of growth velocity at 3 months after gonadotropinreleasing hormone (GnRH) agonist treatment as a predictive value of 1 year growth velocity after treatment in girls with precocious puberty. METHODS: We studied 30 Korean girls with precocious puberty whose chronologic and bone age were less than 9 years and 11 years old, respectively at diagnosis. They treated with a 4 week interval GnRH agonist subcutaneous injections for at least more than 1 year. The patients who were treated with growth hormone simultaneously excluded for this study. Data were collected from chart review retrospectively. We measured heights and calculated growth velocities of the subjects at 3 months and 1 year after GnRH agonist treatment. RESULTS: The mean chronologic age and bone age of the subjects were 8.3 +/- 0.8 year and 10.4 +/- 0.6 years, respectively. The growth velocity at 3 months, 6 months, 9 months and 1 year after GnRH agonist treatment were 7.1 +/- 2.6, 6.6 +/- 2.1, 5.7 +/- 1.3 and 5.8 +/- 0.9 cm/yr, respectively. The positive correlation between the growth velocity at 3 months and 6 months, 9 months, 1 year after GnRH agonist treatment were shown(P < 0.001, P < 0.001, P = 0.002, respectively). CONCLUSION: In this study, the growth velocity at 1 year after GnRH agonist treatment may be predicted by the growth velocity at 3 months after treatment. The patient whose growth velocity at 3 months after GnRH agnoist treatment was low would be needed to observe the growth pattern carefully and to consider combined growth hormone treatment, if needed. It may be deserve further studies to improve final height in patients with central precocious puberty in various conditions.

Salmonellosis is a major bacterial zoonosis that causes self-limited enteritis in animals and foodborne disease and typhoid fever in humans. Recently, multi-drug-resistant strains of Salmonella spp. have increased and caused more serious problems in public health. The present study investigated the antibacterial effects of egg-white lysozyme (EWL) against Salmonella (S.) Typhimurium and the therapeutic effects of EWL for murine salmonellosis. Evaluation of the antibacterial effects of EWL against S. Typhimurium revealed a minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of EWL of 6.25 and 300 µg/mL, respectively. In the bacterial growth inhibition test, EWL at 300 (p < 0.05) and 600 µg/mL (p < 0.01) significantly inhibited the growth of S. Typhimurium at 4 h postincubation. EWL administration at MIC (LYS-1), MBC (LYS-2) and 2× MBC (LYS-3) for 14 days resulted in mortality of mice infected with S. Typhimurium of 70, 40 and 10%, respectively, while that of control mice (CON) was 90%. Counts of S. Typhimurium in murine spleens were significantly lower in LYS-2 and LYS-3 than CON (p < 0.05). The results of this study indicate that EWL has the potential for treatment of ICR mice infected with S. Typhimurium.

PURPOSE: To evaluate the usefulness and effectiveness of endoscopic management for recurrent hematospermia, we performed transurethral endoscopy of the seminal vesicles in patients with recurrent hematospermia, despite the administration of oral medication. MATERIALS AND METHODS: Sixteen patients were enrolled this study. Initially, all patients were treated with oral antibiotics for 6-8 weeks. Transrectal ultrasound (TRUS) and/or MRI were performed to find the anatomic abnormality and its relation with pelvic organs. The mean patient age and duration of symptoms were 43.9 years (range 24-64 years) and 21.3 months (range 1-108), respectively. We used a 6.5Fr. rigid ureteroscope and/or 14Fr. endoureterotomy instruments for the seminal vesiculoscopic examination. Patients were followed for more than 12 months after the procedures. RESULTS: An endoscopic seminal vesicle examination was able to be successfully performed in all patients. A midline cyst was found at 10 cases, which were fulgurated. Endoscopic incisions or dilation of the ejaculatory duct were performed in all patients. An ejaculatory duct stone was found at 5 cases, and removed endoscopically. All patients reported improvement of hematospermia after the procedure, and 3 with perineal discomfort became symptom free. Postoperative complications, such as epididymitis, orchitis and ejaculatory abnormalities, were not observed in any patient. CONCLUSIONS: Transurethral endoscopic interventions of the seminal vesicles can be performed easily with a conventional 6.5Fr. rigid ureteroscope and/or 14Fr. endoureterotomy instruments. Transurethral endoscopic managements were effective and safe treatment options in recurrent hematospermia patients.

In medicolegal investigations, correct identification of the necrophagous fly species collected around and on the corpse is an essential step for estimating the postmortem interval (PMI). Therefore, forensic pathologists and entomologists investigating deaths due to violent crimes need a rapid, easy-to-use protocol to identify fly species found on corpses. A rapid and robust DNA-based tool that can distinguish between various immature and mature species from the Calliphoridae, Muscidae, and Sarcophagidae families would be ideal for such investigations. To date, the DNA barcode initiative is the best approach for identifying species-specific nucleotide sequences. We have developed 3 sequence-characterized amplified region (SCAR)-based identification systems derived from the Abdominal-B homeobox sequences of 17 fly species belonging to the Muscidae and Sarcophagidae. The flies used in this study were collected in Korea. These assay systems can classify 17 forensically important fly species into the dipteran family group and reliably distinguish them from inter- and intraspecific fly species through a 2-step multiplex PCR. This novel approach may also be used as an alternative to conventional DNA-based identification methods.
