Effectiveness of STK Spray® for semen stain localization on solid surfaces: A specificity and sensitivity study.

Semen identification is a crucial step in sexual assault cases. The aim of this study was to assess STK Spray®, a presumptive test for semen, under controlled conditions including, simulated crime scene stains detection. Easy to use, it can be sprayed directly onto different surfaces and visualized under UV light. Several tests were performed on five different substrates (ceramic tile, drywall, metal, wood, and faux leather). The spray was able to enhance semen fluorescence, especially in diluted samples, with characteristic "globular" spots. Although it showed good specificity, false positives could be obtained with 10% bleach. The fluorescence signals were quantified using ImageJ™ and showed a statistically significant substrate-dependent variability. Mixture analysis indicated that saliva did not interfere with detection of semen, while urine partially suppressed the signal and blood markedly affected its interpretation. Simulation tests with UV lamp comparisons confirmed the importance of choosing the right detection method and the utility of this presumptive test in combination with additional immunochromatographic tests. A preliminary signal retention test showed stable fluorescence for up to two years when stains were stored appropriately. Finally, complete DNA profiles (100% of alleles) were obtained from all samples (n = 24) after exposure to the reagent and UV light. Because of its ability to enhance semen signal, especially on specific surfaces, and its rapidity of use and detection, STK Spray® may represent a useful aid in the preliminary screening phase.

Nail aplasia, microcephaly, severe mental retardation and MRI abnormalities: report of two unrelated cases.

We present the clinical and laboratory features of two unrelated mentally retarded females with sporadic bilateral periventricular nodular heterotopia (BPNH), hypoplastic/absent nails and other malformative features. Clinical examination, MRI scanning, EEG recording, karyotyping and neuropsychological testing were performed. From a molecular genetic point of view, direct sequencing analysis, X-inactivation assay and telomere analysis were carried out in one patient. The two patients showed convincing similarities from clinical and neuroradiological points of view with BPNH, mental retardation, microcephaly and hypoplastic/absent nails of fingers and toes. Our two unrelated mentally retarded females may be affected by complex malformative syndromes sharing some common features such as BPNH, mental retardation and hypoplastic/absent nails. Further genetic studies are needed to better understand the pathogenetic bases of this neurological disease. These two cases widen the spectrum of BPNH-associated syndromes.

Tinea incognito in Italy: a 15-year survey.

Tinea incognito or steroid modified tinea is a dermatophytic infection in which topical or systemic steroids, administered as a result of dermatological misdiagnosis or preexisting pathologies, have modified the clinical appearance of the fungal infection, transforming the typical ringworm and mimicking other skin diseases. This is a retrospective study of the agents, clinical aspects, sources of infection of 200 cases (98 males, 102 females, mean age 42 years) of tinea incognito, observed in Siena and Milan, Italy, in the period 1987-2002. In order of decreasing frequency, Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyton floccosum, Microsporum canis, Microsporum gypseum, Trichophyton violaceum and Trichophyton erinacei were isolated. The clinical appearance of the infection was lupus erythematosus discoid-like, eczema-like, rosacea-like, especially on the face, impetigo-like and eczema-like on trunk and limbs. Less often the dermatophytosis resembled psoriasis, purpura, seborrhoic dermatitis and lichen planus. There was folliculitis in 9% of cases and dermatophytid in 3% of cases. Antimycotic therapy brought about clinical and mycological recovery in all patients except one, who had iatrogenic immunodepression.

Practice parameters for sublingual immunotherapy.

The efficacy and safety of sublingual immunotherapy (SLIT) are currently supported by clinical trials, meta-analysis and post-marketing surveys. Practice parameters for clinical use of SLIT are proposed here by a panel of Italian specialists, with reference to evidence based criteria. Indications to SLIT include allergic rhinoconjunctivitis, asthma, and isolated conjunctivitis (strength of recommendation: grade A). As to severity of the disease, SLIT is indicated in moderate/severe intermittent rhinitis, persistent rhinitis and mild to moderate asthma (grade D). SLIT may be safely prescribed also in children aged three to five years (grade B), and its use in subjects aged more than 60 years is not prevented when the indications and contraindication are ascertained (grade D). The choice of the allergen to be employed for SLIT should be made in accordance with the combination of clinical history and results of skin prick tests (grade D). Polysensitisation, i.e. the occurrence of multiple positive response does not exclude SLIT, which may be done with the clinically most important allergens (grade D). As to practical administration, co-seasonal, pre co-seasonal, and continuous schedules are available, being the latter recommended for perennial allergens or for pollens with particularly prolonged pollination, such as Parietaria (grade D). For pollens with relatively short pollination, such as grasses and trees (cypress, birch, alder, hazelnut, olive) the pre co-seasonal and perennial schedules are preferred (grade C). The build-up phases suggested by manufacturers can be safely used (grade A), but they can be modified according to the patient's tolerance (grade C). A duration of SLIT of 3-5 years is recommended to ensure a long-lasting clinical effect after the treatment has been terminated (grade C).

Usefulness of omega-3 fatty acid supplementation in addition to mesalazine in maintaining remission in pediatric Crohn's disease: a double-blind, randomized, placebo-controlled study.

AIM: To assess the value of long-chain omega-3 fatty acids (FAs) supplementation in addition to amino-salicylic-acid (5-ASA) in pediatric patients with Crohn's disease (CD). METHODS: Thirty-eight patients (20 males and 18 females, mean age 10.13 years, range 5-16 years) with CD in remission were randomized into two groups and treated for 12 mo. Group I (18 patients) received 5-ASA (50 mg/kg/d)+ omega-3 FAs as triglycerides in gastro-resistant capsules, 3 g/d (eicosapentanoic acid, EPA, 400 mg/g, docosahexaenoic acid, DHA, 200 mg/g). Group II (20 patients) received 5-ASA (50 mg/kg/d)+olive oil placebo capsules. Patients were evaluated for fatty acid incorporation in red blood cell membranes by gas chromatography at baseline 6 and 12 mo after the treatment. RESULTS: The number of patients who relapsed at 1 year was significantly lower in group I than in group II (P<0.001). Patients in group I had a significant increase in the incorporation of EPA and DHA (P<0.001) and a decrease in the presence of arachidonic acids. CONCLUSION: Enteric-coated omega-3 FAs in addition to treatment with 5-ASA are effective in maintaining remission of pediatric CD.

Eighty-four consecutive cases of tinea faciei in Siena, a retrospective study (1989-2003).

Consecutive cases of tinea faciei diagnosed in Siena between 1989 and 2003 were studied retrospectively for differences in clinical form, demographic data and species of dermatophyte isolated. The series consisted of 84 cases (59 females, 25 males) with a mean age of 27 years. Mean age of females (32.4 years) was significantly greater than that of males (14.2 years). The dermatophytes most frequently isolated were Microsporum canis (38 cases) and Trichophyton rubrum (31 cases). Clinical form was typical of tinea in 54 subjects (64.3%) and was tinea incognito because of inappropriate therapy in the other 30 (35.7%) subjects. The mean age of patients with the typical form (19.2 years) was significantly lower than that of those with tinea incognito (41.1 years). All cases in the age range 6-15 years had typical tinea, whereas the maximum frequency of cases with tinea incognito was 46-50 years. In the group with tinea incognito there was a majority of women and the dermatophytes isolated differed with gender. No such difference was observed in the group with typical tinea.

Onychomycosis in children: a survey of 46 cases.

This is a retrospective study of the agents, clinical aspects, sources of infection and therapy of onychomycosis in children. In the period 1989-2000, we observed 46 consecutive children, until 16 years of age with onychomycosis (29 boys, 17 girls, mean age 10.8 years). Dermatophytes were isolated in 30 cases (Trichophyton rubrum in 22 cases, Trichophyton mentagrophytes in five, Epidermophyton floccosum in two and Trichophyton violaceum in one) and Candida spp. in 16, associated with Trichophyton rubrum in two. Moulds were isolated in three children (Fusarium oxysporum in one, Scopulariopsis brevicaulis in another and Aspergillus fumigatus associated with Trichophyton rubrum in a third). The commonest features were distal and distolateral subungual hyperkeratosis in dermatophyte infections (93%) and onychodystrophy and paronychia in Candida infections (56% and 50% respectively). Forty patients achieved clinical and mycological recovery. It is appropriate to suspect onychomycosis in children, perform microbiological diagnosis and undertake early treatment. An approach of this kind may help to prevent nail dystrophy and the spread of infection.

Subcutaneous alternariosis.

A case of subcutaneous alternariosis caused by Alternaria alternata is reported in a 52-year-old male who underwent kidney transplantation 1 year earlier. The infection manifested as a vegetating mass about 7 cm in diameter on the right forearm. Histological examination with Grocott staining and periodic acid-Schiff diastase revealed fungal spores and hyphae with chronic granulomatous inflammation. Biopsy fragments inoculated on Sabouraud-glucose agar with chloramphenicol produced colonies which were identified as Alternaria alternata on the basis of macroscopic and microscopic characters.

Sex differences in carpal tunnel syndrome: comparison of surgical and non-surgical populations.

Carpal tunnel syndrome (CTS) patients are known to show gender-related differences in severity. The main aim of this cross-sectional study was to determine whether these differences between women and men may be related to age, education or body mass index (BMI) in two populations, one with idiopathic CTS not treated surgically and the other with idiopathic CTS treated by surgical decompression. A secondary aim was to check differences in surgical results between the genders in the surgical population. The non-surgical population consisted of 172 subjects (126 women and 46 men, mean age 55.1 years) whose data were obtained at electrophysiological examination. The surgical population consisted of 219 patients (177 women and 42 men, mean age 55.1 years) whose data were obtained before surgery. Age, education, BMI, duration of symptoms, electrophysiological and clinical severity of CTS (with ordinal scales), and the self-administered Boston Questionnaire (BQ) of symptoms and functional status of hands were considered. There were no differences in age or clinical and electrophysiological severity between women and men in either group, except for distal motor latency of the median nerve that was more delayed and duration of symptoms that was shorter in men than women in non-surgical sample. Men had a higher BMI than women. Women had higher BQ scores in the surgical and non-surgical samples. These differences remained when the results were analysed matching the men with an identical number of women of the same age, education and BMI. In the surgical population, the results of surgical decompression did not modify the gender-related differences in severity. As in many other syndromes and diseases, for a given clinical severity, women with CTS were more sensitive than men in reporting their symptoms. Risk factors of CTS, such as age, education and BMI, were not responsible for these differences. The results of surgical decompression were similar in men and women.

Homocysteine and related genetic polymorphisms in Down's syndrome IQ.

OBJECTIVE: Down's syndrome (DS) is the most frequent genetic cause of Alzheimer-type dementia. Its metabolic phenotype involves an increased trans-sulphuration of homocysteine. The aim of the present study was to investigate the influence of homocysteinaemia (t-Hcys), folate, vitamin B(12), and related polymorphisms on intelligence quotient (IQ) in DS. METHODS: The IQ of 131 patients with trisomy 21 from a specialist centre in Sicily was determined and classified according to DMS-IV. The effects of age, folate, vitamin B(12), t-Hcys, and genetic polymorphisms on IQ were evaluated separately and in combination using regression analyses. RESULTS: IQ was significantly lower in DS patients with t-Hcys >7.5 micromol/l (median) and in those who were carriers of methylenetetrahydrofolate reductase (MTHFR) 677 T allele and of methylenetetrahydrofolate reductase 677 T and transcobalamin 776 G combined alleles (p = 0.0013, p = 0.0165, and p = 0.0074, respectively). The IQ correlated significantly with t-Hcys and folate in single and multiple regression analyses, independently of age. In addition, t-Hcys >9.6 micromol/l (upper quartile) was found to be associated with low IQ (<40, median of study group) with an odds ratio of 2.61 (p = 0.0203). The odds ratio was increased by threefold in carriers of MTHFR 677T allele. The MTHFR 677T allele/transcobalamin 776 G allele combination was associated with the risk of DS patients to have an IQ less that the median with an odds ratio of 2.68 (95% CI 1.26 to 5.70, p = 0.0104). CONCLUSION: This study found evidence of an association between t-Hcys and MTHFR 677 T and transcobalamin 776 G alleles with IQ in patients with DS. The association may be related to a defective remethylation of homocysteine, affecting IQ.
