Amniography in the prenatal diagnosis of neural tube defects.

Amniography for the visualization and confirmation of suspected neural tube defect was performed in 9 midtrimester gravidas. In all cases, amniotic fluid alpha-feto protein (AFP) was abnormally elevated. Four cases of anencephaly and one of spina bifida were demonstrated by amniography. These pregnancies were terminated and the defects were confirmed by gross pathologic examination. In 4 remaining cases, amniography was normal. Three of these pregnancies proceeded to term, culminating in the birth of a normal child. The fourth patient had spontaneous abortion of a normal fetus at 23 weeks of gestation. The experience reported here suggests that amniography is an important adjunctive diagnostic technique in the prenatal diagnosis of neural tube defect, and if used correctly, may significantly reduce the chance of false-positive diagnosis.

Traumatic spinal epidural hematoma-unusual cause of torticollis in a child.

Traumatic spinal epidural hematoma is rare in children. The presentation could be nonspecific, leading to a delay in diagnosis. We present an infant who sustained an epidural hematoma after a "trivial" injury. The delay in diagnosis led to minor neurological deficit at 6-week follow-up. Irritability and torticollis after a neck trauma in an afebrile child should alert to the possibility of spinal cord compression. Early imaging and early decompression will minimize morbidity.

Effects of AGI-1096, a novel antioxidant compound with anti-inflammatory and antiproliferative properties, on rodent allograft arteriosclerosis.

BACKGROUND: AGI-1096 is a novel phenolic intracellular antioxidant with anti-inflammatory and antiproliferative properties. In vitro, AGI-1096 inhibited the inducible expression of vascular cell adhesion molecule (VCAM)-1, E-selectin, and monocyte chemoattractant protein (MCP)-1 in endothelial cells and tumor necrosis factor (TNF)-alpha and interleukin (IL)-1beta secretion from lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells. It also inhibited serum-stimulated proliferation of aortic smooth-muscle cells. In vivo, AGI-1096 demonstrated anti-inflammatory properties in a murine delayed-type hypersensitivity model. Given these antioxidant, anti-inflammatory and antiproliferative properties, we reasoned that AGI-1096 may be able to prevent chronic allograft arteriosclerosis. This hypothesis was tested in a rodent aortic transplantation model. METHODS: Donor descending aortas from August-Copenhagen-Irish rats were heterotopically transplanted into Lewis rat abdomens in end-to-end fashion. Animals were assigned to six groups as follows: AGI-1096 0 mg/kg per day (vehicle, n = 10), 10 mg/kg per day (n = 10), 20 mg/kg per day (n = 10), 40 mg/kg per day (n = 10), positive control (cyclosporine A 10 mg/kg per day by oral gavage, n = 10), and isograft negative control (Lewis-to-Lewis, n = 5). AGI-1096 was administrated subcutaneously to recipient animals three days before the surgery and for 90 days thereafter. On day 90, the paraffin-embedded allograft sections were stained with Elastin-van Gieson's stain, and the intima/media (I/M) ratio and luminal narrowing (1%LN) was assessed by digital morphometry. RESULTS: AGI-1096 demonstrated dose-dependent lowering of the I/M ratio and %LN when compared with vehicle controls. CONCLUSION: This is the first study to show that treatment of allograft recipients with AGI-1096 decreases the incidence of transplant arteriosclerosis. These data suggest that AGI-1096 may be a promising new therapeutic agent for use in clinical transplantation.

Superoxide dismutase mimetic m40401 reduces ischemia-reperfusion injury and graft coronary artery disease in rodent cardiac allografts.

BACKGROUND: The oxidative stress associated with ischemia-reperfusion (I/R) of cardiac allografts leads to production of injurious cytokines and expression of proinflammatory adhesion molecules. This is one of the most important alloantigen-independent factors associated with graft coronary artery disease (GCAD). M40401 is a newly developed cell permeable superoxide dismutase mimetic, which has been shown to scavenge superoxide anion with highly specific and enhanced catalytic activity. We hypothesized that M40401 would exert a protective effect in I/R injury of cardiac allografts and ameliorate the progression of GCAD. METHODS: Recipient ACI rats were pretreated with M40401 or vehicle control. PVG donor hearts were heterotopically transplanted into the abdomen of ACI recipients. Cardiac allografts were analyzed for adhesion molecule mRNA expression and tumor necrosis factor-alpha expression after 4 hr of reperfusion. Neutrophil infiltration was detected by myeloperoxidase activity. Intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and endothelial leukocyte adhesion molecule-1 mRNA were detected by reverse-transcriptase polymerase chain reaction. Immunohistochemical analysis of adhesion molecule expression was also performed. Additional grafts were procured 90 days after transplantation and assessed for the development of GCAD by computer-assisted image analysis. RESULTS: In the M40401-treated group, adhesion molecule expression was significantly less than in the vehicle control group. Treated grafts also had lower myeloperoxidase activity and tumor necrosis factor-alpha concentration compared with controls. Neointimal proliferation and intima to media ratios in M40401-treated allografts were significantly decreased compared with controls. CONCLUSIONS: Selective removal of superoxide anion by M40401 results in inhibition of I/R injury. Furthermore, M40401 treatment decreases the development of oxidative stress-associated GCAD. This treatment strategy may have broad cardioprotective applications for all cardiac operations in addition to cardiac transplantation.

Results of a controlled trial of the acaricide paragerm on Dermatophagoides spp. in dwelling houses.

The effect of Paragerm spray from either a hand pressurized can or from a general room mist device (MCR device) on mattress mite populations was compared with the effect of a control spray. After 1 month a reduction in mite population due to the cleaning procedures was evident in the control treated mattresses; Paragerm treated mattresses had significantly fewer mites, notably those treated with the aerosol can spray, nine out of fifteen of which were mite free. Dissection of the mattresses showed that some mites survive and they could form the nucleus from which reinfestation could occur.

In vitro comparison of the cytotoxicity of twelve endodontic materials using a new technique.

An in vitro method for the cytotoxicity testing of endodontic materials is described which aims to simulate the clinical situation. Materials can be tested in the presence or absence of a compacted layer of dentine chips mimicking the periapical dentine plug. A total of twelve materials were tested. In the absence of dentine, Kloroperka, Biocalex, Diaket and Endomethasone were slightly cytotoxic; AH26 with and without silver, Sealapex, Tubliseal and Kerr's pulp canal sealer were moderately cytotoxic, while Forfenan, Spad and Kri paste were strongly cytotoxic. In the presence of dentine the cytotoxicity of these materials was considerably reduced, with the exception of Endomethasone, Forfenan, Spad and Kri paste. The method provides a satisfactory alternative to implantation testing and is an inexpensive and reproducible test system in which dentine can be incorporated.

A comparison of endodontic treatment results at two dental schools.

Endodontic treatment results were assessed in a controlled clinical study in Arhus. Undergraduate students used either Kloroperka or AH26 as sealer in a randomized fashion. The findings were compared with the results from a previous study of identical design in Oslo, which involved Kloroperka, AH26 and ProcoSol. While Kloroperka performed slightly, but significantly less well than AH26 or ProcoSol in the Oslo study, no difference was found between Kloroperka and AH26 in the present study. The overall treatment results were poorer in Arhus than in Oslo, but this might be explained by a marked difference in the preoperative diagnoses and in the technical problems associated with the teeth selected for treatment. When results of endodontic treatment carried out at different locations are compared, variations in case selection and preoperative diagnoses must be corrected for in order to obtain an adequate basis for comparison.

Facial nerve function and hearing preservation after retrosigmoid excision of vestibular schwannoma: Christchurch Hospital experience with 97 patients.

BACKGROUND: Between January 1988 and December 2002, 97 patients underwent surgery for excision of vestibular schwannoma via the retrosigmoid approach at Christchurch Hospital. METHODS: A retrospective review was undertaken of the clinical notes with emphasis on facial nerve function and hearing preservation postoperatively. RESULTS: Of patients with small and medium-sized tumours, 81% had good facial nerve function at 1 year (House-Brackmann grade 1 and grade 2), 16% had moderate function (grade 3 and grade 4) and 3% had poor function (grade 5). Of patients with large tumours, 22% had good facial function (grade 1 and grade 2), 37% had moderate function (grade 3 and grade 4) and 41% had poor function (grade 5 and grade 6). Useful postoperative hearing was preserved in 21% of the 47 patients with tumours <3 cm and useful preoperative hearing. In the last 5 years the authors have been operating in conjunction with an ear, nose and throat surgeon (PAB) trained in base-of-skull surgery. Over this period, useful hearing was preserved in 32% of patients with small and medium-sized tumours and useful preoperative hearing. CONCLUSIONS: Tumour size was an important predictor of the postoperative facial and cochlear nerve function. The multidisciplinary approach to these tumours offers better results. These results compare well with other published series.

Health and social service utilization among elderly immigrants from the former Soviet Union.

PURPOSE: To explore factors that affect health and social service use among elderly Russian immigrants from the perspectives of the elders, their adult caregiving children, and the health and social service professionals who serve them. METHODS: A qualitative, case-oriented study design was used and 17 elderly Russian immigrants, 8 adult caregiving children, and 15 health professionals were interviewed in the Boston area in 1998. Perceptions about the patterns of and reasons for Russian elders' health and social service use were summarized through content analysis of the interview data. FINDINGS: Participants across groups perceived extensive service use by elderly Russian immigrants. Life circumstances associated with immigration, cultural norms and beliefs, and structural characteristics of the local Russian immigrant community accounted for service use. CONCLUSIONS: Findings indicate that providing support for depression and loneliness associated with immigration, educating immigrants about the role of primary care providers in the US as well as realistic expectations for American medicine, and managing care to decrease the use of unnecessary services would facilitate appropriate service use among elderly Russian immigrants.
