Rothmund-Thomson syndrome (RTS) with osteosarcoma due to mutation.

Rothmund-Thomson syndrome (RTS) is a rare autosomal recessive disorder with clinical features consisting of poikiloderma, skeletal abnormalities, sparse hair, absent or scanty eyelashes and eyebrows and short stature. Patients with RTS due to genetic mutations of genes carry a high risk of developing osteosarcoma during childhood. Because of this, early genetic diagnosis is important.

Adherence to hydroxyurea medication by children with sickle cell disease (SCD) using an electronic device: a feasibility study.

Adherence to hydroxyurea (HU) is a significant modifying factor in sickle cell vaso-occlusive pain. We conducted a study using an electronic medication container-monitor-reminder device (GlowCap™) to track adherence and determine whether use of this device affected rates of HU adherence. Subjects were regular attendees to our clinic.

Pain management trend of vaso-occulsive crisis (VOC) at a community hospital emergency department (ED) for patients with sickle cell disease.

Pain management at the emergency department (ED) for vaso-occulsive crisis (VOC) for patients with sickle cell disease has not been optimum, with a long delay in giving the initial analgesic. We conducted a retrospective survey over a 7-year period to determine our ED's timing in giving pain medication to patients with VOC as a quality improvement project. We compared different periods, children vs adults, and the influence of gender in the analgesic administration timing.

Forme Fruste of HLH (haemophagocytic lymphohistiocytosis): diagnostic and therapeutic challenges.

Infants and young children often present with a persistent febrile episode, sick appearance and negative infectious disease work-up. These patients present serious diagnostic and therapeutic problems to those who provide medical care, particularly since these children are clinically sick. We present a 13 month old child who presented with this clinical challenge.

Postinduction Supportive Care of Pediatric Acute Myelocytic Leukemia: Should Patients be Kept in the Hospital?

Children with AML become profoundly neutropenic while they undergo remission induction chemotherapy. It is unknown whether these children should be kept in the hospital while they are severely neutropenic to prevent life-threatening complications associated with neutropenia and reduce fatality. We at our institution routinely discharge patients after completing remission induction chemotherapy in the presence of profound neutropenia, unless it is clinically contraindicated.

Acute haemolytic anaemia and myolysis due to G6PD deficiency.

A 2-year-old African-American male patient with sickle cell trait developed cough, red coloured urine, pallor and fatigue. The patient was hospitalised. Diagnostic workup showed that he was glucose 6 phosphate dehydrogenase (G6PD) deficient in erythrocytes.

A rapid increase in the normal white cell counts without blasts as the initial presentation of T-cell acute lymphoblastic leukaemia.

A 5-year-old girl with multiple enlarged cervical lymph nodes consistent with Epstein-Barr virus infection showed a rapid increase in the white blood cell counts (myeloid cells and lymphocytes) without blasts over a week period. Bone marrow evaluation performed after a week's observation unexpectedly showed replacement of the marrow with T lymphoblasts. A presentation of T-cell acute lymphoblastic leukaemia (T-ALL) in this fashion is very unusual.

Clear cell sarcoma of the jaw: a case report and review of the literature.

Clear cell sarcoma (CSS) is a unique malignant soft tissue tumor that mainly occurs from the aponeurotic tissue and tendons of extremities. It is rare in the pediatric population. The tumor does not respond well to chemotherapy or irradiation.

Symptomatic erythrocytosis associated with a compound heterozygosity for Hb Lepore-Boston-Washington (δ87-β116) and Hb Johnstown [β109(G11)Val→Leu, GTG>TTG].

Hb Johnstown [β109(G11)Val→Leu, GTG>TTG] has previously been described as a high oxygen affinity variant in a heterozygous state and in combination with β(0)-thalassemia (β(0)-thal). Because the variant does not separate from Hb A by routine methods it may be easily missed unless clinical suspicion is high. Hb Lepore-Boston-Washington (Hb LBW; δ87-β116) is a δβ hybrid variant that clinically manifests similarly to a β(+)-thal.

Multiple fractures due to osteogenesis imperfecta mistaken as child abuse.

Unlabelled: A 15-month-old African-American boy receiving chemotherapy for Wilms tumour was diagnosed to have a fracture of left femur at the emergency department (ED) of our hospital. A month earlier, the patient had been seen at the same ED for a fracture of right femur. The skeletal survey this time also showed an old posterior rib fracture.

Optimal conditions for visualizing water-conducting pathways in a living tree by the dye injection method.

To elucidate the water-conducting pathways in living trees by the dye injection method, suitable sample preparation procedures are needed. We evaluated quantitatively the properties and concentrations of three dyes (acid fuchsin, basic fuchsin and safranin) widely used for this purpose, and determined the optimal conditions required to avoid artifacts after dye injection into the sap stream of Pieris japonica D. Don.

[Epidemiological survey of sexually transmitted male urethritis in Kyoto Prefecture].

The data of sexually transmitted urethritis in males have been collected at 24 institutes in Kyoto Prefecture since October, 2002. The data collected from January to December in 2004 are summarized herein. A total of 1,275 patients were diagnosed with urethritis during this period.

Evaluation of the compression characteristics and physical properties of the newly invented one-step dry-coated tablets.

This study was conducted in order to clarify the compression characteristics, and to confirm the superiority of the physical properties, of the newly invented One-Step DRy-Coated tablets (OSDRC). We compared both the compression characteristics and the physical properties of OSDRC with those of physical-mixture tablets (PM) that were prepared with the same ingredients, quantity, and compression pressures. We selected potassium chloride (KCl) and acetaminophen (AAP) as the model drugs, since the former is known for its appropriate compression characteristics and the latter for its brittleness.

Comparison of the compression characteristics between new one-step dry-coated tablets (OSDRC) and dry-coated tablets (DC).

One-step dry-coated tablets (OSDRC) were prepared using materials which are generally used in pharmaceutical tablets. The radial tensile strength of OSDRC was measured for various compression pressures and core porosities before the final compression to compare with that of conventional dry-coated tablets (DC). Furthermore, stress relaxation in the compression process was investigated.
