Group A

Tonsillitis is a frequently encountered pathology in the outpatient setting, usually caused by viruses [1]. When bacterial, the most common causatory microbe is streptococcus group A [1]. Tonsillar and peritonsillar abscess (PTA) on the other hand are never viral, and are usually caused by streptococcus pyogenes, Streptococcus melleri, fusobacterium necrophorum and staphylococci [1,2]. The overall incidence of PTA is suggested to be 37/100,000 patients, with the highest incidence between ages 14-21 at 124/100,000 [3].

Cortisol Levels

This pilot study aimed at assessing the feasibility of capturing physiological evidence of reduced stress for hospitalized children following expressive arts therapy. Twenty-five patients were offered a novel form of expressive arts therapy, termed Healing Sock Creatures, during their stay in the hospital. Saliva samples were collected at two times in the afternoon for the purpose of measuring salivary cortisol levels. The patients were randomly assigned to two groups, a treatment group or a wait-list control group. A trend of decreased cortisol levels was apparent following therapy in the treatment group and concurrent steroid treatment, which is common in intensive care units, does not appear to interfere with the ability to measure decreased cortisol levels following therapy. Our results support the design of a formal study to assess physiological biomarkers of stress in hospital settings. To our knowledge, this is the first in-patient study assessing a biomarker of stress following expressive arts therapy for children

The respiratory viruses are recognized as the most frequent lower respiratory tract pathogens for infants and young children in developed countries but less is known for developing populations. The authors conducted a prospective study to evaluate the occurrence, clinical patterns, and seasonal trends of viral infections among hospitalized children with lower respiratory tract disease (Group A). The presence of respiratory viruses in children's nasopharyngeal was assessed at admission in a pediatric ward. Cell cultures and immunofluorescence assays were used for viral identification. Complementary tests included blood and pleural cultures conducted for bacterial investigation. Clinical data and radiological exams were recorded at admission and throughout the hospitalization period. To better evaluate the results, a non- respiratory group of patients (Group B) was also constituted for comparison. Starting in February 1995, during a period of 18 months, 414 children were included- 239 in Group A and 175 in Group B. In Group A, 111 children (46.4%) had 114 viruses detected while only 5 children (2.9%) presented viruses in Group B. Respiratory Syncytial Virus was detected in 100 children from Group A (41.8%), Adenovirus in 11 (4.6%), Influenza A virus in 2 (0.8%), and Parainfluenza virus in one child (0.4%). In Group A, aerobic bacteria were found in 14 cases (5.8%). Respiratory Syncytial Virus was associated to other viruses and/or bacteria in six cases. There were two seasonal trends for Respiratory Syncytial Virus cases, which peaked in May and June. All children affected by the virus were younger than 3 years of age, mostly less than one year old. Episodic diffuse bronchial commitment and/or focal alveolar condensation were the clinical patterns more often associated to Respiratory Syncytial Virus cases. All children from Group A survived. In conclusion, it was observed that Respiratory Syncytial Virus was the most frequent pathogen found in hospitalized children admitted for severe respiratory diseases. Affected children were predominantly infants and boys presenting bronchiolitis and focal pneumonias. Similarly to what occurs in other subtropical regions, the virus outbreaks peak in the fall and their occurrence extends to the winter, which parallels an increase in hospital admissions due to respiratory diseases.

AbstractA 72-year-old man presented with an erythematous, painful, swollen, and blistering left hand associated with a systemic fever. The patient was diagnosed with microscopic polyangiitis and was receiving steroid therapy from a year before the incident. Based on a clinical diagnosis of necrotizing fasciitis, emergency surgery was performed within 2 days after the onset. β-Hemolytic Streptococcus group A was isolated from a culture of the blood and wound. Radical debridement and high-dose penicillin and clindamycin therapy successfully saved the patient's life and affected limb except for the second finger on his left hand, which was completely necrotic. However, the function of the left hand was seriously decreased and did not recover. The important point to note in this case was the preexisting vasculitis neuropathy due to microscopic polyangiitis. The severe postoperative dysfunction of the hand was considered to be due to ischemic neuropathy that was aggravated by compartmental syndrome and microvascular thrombosis. In conclusion, necrotizing fasciitis of an extremity with underlying vasculitis neuropathy can lead to a poor functional prognosis of the limb.

Abstract Acute myelocytic leukemia (AML) in Down Syndrome (DS) children is characterized by a young age of onset (< 2 years), a low white blood cell count and high frequency of Megakaryocytic leukemia. DS children with AML have higher disease free survival (DFS) rates as compared to non DS AML patients. Previous studies have suggested that intensification chemotherapy may not be necessary for the treatment of DS children with AML. The objective of this study was to clarify the effectiveness and toxicities of using high dose Cytosine Arabinoside (HD AraC) intensification in the treatment of DS AML. Clinical data for children (<14 years) with DS AML, diagnosed between September 2000 to May 2005, were retrieved from the hospital data base. Patients were divided into two groups; Group A patients received chemotherapy containing HD AraC, while Group B patients did not. A total of 15 patients were included, eight in Group A and seven in group B. The median age at diagnosis was 22 months (A=23 months, B=22 months). The two groups were matched regarding their clinical and laboratory parameters. There was no significant difference in DFS between groups A and B, 75% and 85% respectively (P = 0.82) at a mean observation period of 42.9 months for group A and 23.12 months for group B. The median time to relapse was 6 months for group A and 8 months for group B. The overall treatment related toxicity was higher in Group A patients but achieved only borderline significance (P = 0.06). However, when toxicity was assessed separately for induction and post induction phases of chemotherapy there were significantly more infectious events (17 v. 2; p=0.0006) in the post induction phase which includes HD AraC intensification in Group A. Even when only serious infections (bacteremia, fungal infection, sepsis) were included in the evaluation this difference persisted (7 v. 1; p=0.0339), with less toxicity for Group B patients. No such difference was noted between the two groups during induction chemotherapy. In conclusion the use of HD AraC in post-induction intensification phases for DS AML children does not improve DFS and is associated with more treatment related toxicity.

The PEGA resin, a beaded polyethylene glycol dimethylacrylamide copolymer, was evaluated as an affinity support for the purification of carbohydrate-binding macromolecules, namely, the cation-independent mannosyl phosphate receptor (CI-MPR) and a polyclonal antibody directed against a Streptococcus Group A oligosaccharide. Two polyethylene glycol (PEG) derivatives, a di-acryloylated PEG1900derivative or a longer di-acryloylated PEG4000derivative, were used as cross-linkers. The longer cross-linker was synthesized in four steps from polyethylene glycol 4000. The mannosyl 6-phosphate (M6P)-containing immunoaffinity columns were prepared through the inverse suspension radical copolymerization of the corresponding allyl glycoside with acrylamide and the PEG cross-linker. The resin with the shorter cross-linker (PEG1900derivative) had a 6.3% molar cross-linking while that with the longer cross-linker (PEG4000derivative) had a 3.8% molar cross-linking. For the Streptococcus Group A trisaccharide-containing immunoaffinity columns, three PEGA affinity supports bearing free amino groups were prepared and subsequently substituted with a trisaccharide activated as its squarate adduct. While one resin contained the shorter cross-linker PEG1900and had a 3% molar cross-linking, the other two resins contained the longer cross-linker PEG4000 with a molar cross-linking of 5% and 3%, respectively. In affinity chromatographic studies, the M6P-containing columns were ineffective in retaining the cation-independent mannosyl phosphate receptor (CI-MPR, ~ 215kDa), whereas antibody (~ 150kDa) retention was observed with two of the three Streptococcus Group A trisaccharide-containing immunoaffinity columns. Key words: PEGA resins, immunoaffinity supports, carbohydrate ligands, antibody purification.
