Porphyromonas gingivalis is strongly implicated in the pathogenesis of adult periodontitis, the major cause of tooth loss in adults. Use of an antibacterial agent controlling P. gingivalis as a periodontal therapeutic agent has been rationalized. The present study was performed to observe the antibacterial effect of inorganic polyphosphates (polyP) on P. gingivalis. P. gingivalis 2561 was grown in half-strength brain-heart infusion broth containing hemin and vitamin K with or without polyP. Minimal inhibitory concentration (MIC) of polyP with various chain lengths was determined by measuring the absorbance of the grown cells at 540 nm. MIC of polyP for the bacterium was determined to be 0.05%. The effect of polyP with a chain length of 75 (polyP 75) was further examined. PolyP 75 added to the growing culture of P. gingivalis at its exponential phase was as effective in inhibiting the growth of P. gingivalis as polyP 75 added at the very beginning of the culture. More than 99% of the cells lost their viability determined by viable cell count when polyP 75 was added to the culture of growing P. gingivalis at the concentration of 0.06%, suggesting that polyP 75 has a bactericidal effect on the bacterium. Intracellular nucleotide release from the cells was increased by approx. 20% in the presence of polyP 75 but was not reversed by the addition of divalent cations like Ca++ and Mg++. Under the transmission electron microscope, only a small number of the growing P. gingivalis cells were actually lysed. However, the majority of the cells appeared to be atypical in their shape, demonstrating accumulation of highly electron-dense granules and bodies of condensed nucleic acid-like material in the cytoplasm. In the presence of polyP 75, the protein profile of P. gingivalis was changed as determined by SDS-polyacrylamide gel electrophoresis and immunoblot, and the proteolytic activity of the bacterium demostrated on the zymograms was decreased. The overall results suggest that polyP have a strong bactericidal activity against P. gingivalis in which lysis in relation to chelation may not play the major role but unknown mechanism that possibly affects the viability of the bacterium may be involved. PolyP may be used as an agent for prevention and treatment of periodontitis.

Congenital chloridorrhea is a rare autosomal recessive disease and results from impairment of active transport of chloride in the ileum and colon. Absence of the Cl-/HCO3-, exchange pump causes polyhydramnios, distended bowel loop and absence of meconium before birth. Prenatal ultrasound examination shows a great number of circular anechoic area in the fetal abdomen, as well as polyhydramnios. Massive watery diarrhea is apparent from the first days of life. This fluid loss, with its attendant impairment of electrolyte homeostasis, is life threatening. Exact replacement of water, NaCl and KCl can prevent the growth and psychomotor retardation and the development of progressive renal damage. We experienced one case of congenital chloridorrhea and present it with brief review of literatures.

Abdominal actinomycosis is a rare and chronic progressive disease, especially in children. Clinically, it has non-specific symptoms and diagnostic findings as well as low prevalence, making it very difficult to diagnose prior to intraoperative pathological confirmation. For this reason, abdominal actinomycosis is commonly misdiagnosed as appendicitis. After the histopathological diagnosis of abdominal actinomycosis is made, patients should be administered an appropriate antibiotic such as penicillin. Here we describe a case of appendiceal actinomycosis in an 18-year-old girl who was initially diagnosed with acute appendicitis.

Although congenital syphilis can be prevented with prenatal screening, the disease remains problematic. Currently, there are no cases that describe hematuria and pneumonia related to congenital syphilis. We report a case of congenital syphilis that involved nephrotic syndrome and pneumonia alba in a 22-day-old male infant whose mother did not receive adequate prenatal care. The congenital syphilis diagnosis was confirmed with a serologic test and the patient recovered with penicillin treatment. Clinical findings may be subtle in neonates and delayed recognition occurs frequently, thus complete prenatal screening is critical for congenital syphilis prevention. Immediate serologic testing should be performed to obtain a differential diagnosis if an infant is delivered by a mother that has not received appropriate prenatal examinations.

OBJECTIVE: To assess the anatomical relationship between spinous process of the lumbar vertebrae and iliolumbar ligament from a viewpoint of surface anatomy. METHOD: Fourteen iliolumbar ligaments of seven human cadavers were dissected and measured distance from the lumbar spinous process to the iliolumbar ligament and vertical depth of iliolumbar ligament from the skin surface. RESULTS: All 14 iliolumbar ligaments were originated at the L5 transverse process and inserted in anterior surface of the iliac crest. Direct distance from lumbar spinous process to the origin siteof the iliolumbar ligament was 7.67+/-0.39 cm(distance from the spinous process to presumed skin point of the termination site of the ligament, 6.71+/-0.4 cm). Vertical depth from skin surface was 3.94+/-0.57 cm to the origin site of the iliolumbar ligament, and 3.67+/-0.54 cm to the termination site of the iliolumbar ligament. CONCLUSION: The iliolumbar ligament was deep seated anatomical structure in the lumbosacral region. Superficial landmark of the lumbar spinous process may be useful in approach to iliolumbar ligament.

Umbilical cord blood is an attractive source of hematopoietic stem cells in allogeneic hematopoietic stem cell transplantation. Umbilical cord blood transplantation has merits of rapid availability and low risk of severe acute graft versus host disease. Umbilical cord blood should be an important source of stem cell transplantation for patients who have no suitable human leukocyte antigen-matched bone marrow, or peripheral stem cell donor. Transplantation of umbilical cord blood is limited by insufficient cell doses. This had led to the alternative concept of attempting to increase the number of cell doses using two cord blood units from different donor. We report a case of double-unit cord blood transplantation for 55-year-old male with primary refractory acute myeloid leukemia.

Group A streptococcus (GAS) rarely causes meningoencephalitis in children without risk factors. A previously healthy 8 year-old child presented with lethargy, high fever, and vomiting. The clinical course was unusual including intractable seizures, disseminated intravascular coagulation (DIC), and left hemiparesis in spite of the appropriate and timely administration of antibiotics and corticosteroids. The microbiologic studies revealed that the pathogen was susceptible to penicillin and GAS M18 strains. This case showed the importance of the GAS vaccine in addition to appropriate antibiotics.
