Management of severe head injury with brain exposure in three loggerhead sea turtles Caretta caretta.

The loggerhead Caretta caretta is the most common sea turtle in the Mediterranean. Currently, sea turtles are considered endangered, mainly due to the impact of human activities. Among traumatic lesions, those involving the skull, if complicated by brain exposure, are often life-threatening. In these cases, death could be the outcome of direct trauma of the cerebral tissue or of secondary meningoencephalitis. This uncontrolled study aims to evaluate the use of a plant-derived dressing (1 Primary Wound Dressing®) in 3 sea turtles with severe lesions of the skull exposing the brain. Following surgical curettage, the treatment protocol involved exclusive use of the plant-derived dressing applied on the wound surface as the primary dressing, daily for the first month and then every other day until the end of treatment. The wound and peri-wound skin were covered with a simple secondary dressing without any active compound (non-woven gauze with petroleum jelly). Data presented herein show an excellent healing process in all 3 cases and no side effects due to contact of the medication with the cerebral tissue.

Anticyclic-citrullinated protein antibodies in the diagnosis of ophthalmic inflammatory disease.

While rheumatoid factor (RF) testing has been previously used in the detection of rheumatoid arthritis (RA), its effectiveness has been limited by poor rates of sensitivity and specificity and its positivity in multiple other disease states. Given its enhanced specificity, quantification of anticyclic-citrullinated protein (anti-CCP) antibodies has emerged as a standard in molecular testing for RA. Despite the importance of this test in clinical rheumatology, we are unaware of any reports of its use in the detection of uveitis or orbital disease. In this report, we characterize the first use of anti-CCP in the diagnosis of orbital disease.

[Chronic-degenerative diseases in health care activities: data from health surveillance of Federico II University General Hospital in Naples]. / Patologie cronico-degenerative nelle attività assistenziali: i dati nell'Azienda Ospedaliera Universitaria Federico II di Napoli.

Recent average life increase, as well as new habits and lifestyles assumption, has determined a change in population health profiles, as a result of progressive increase in chronic-degenerative diseases prevalence. Among these latter; musculoskeletal and cardiovascular diseases are the most frequent ones. Health care workers also suffered from this change in health profiles. This study, performed thanks to the extension of Health Surveillance to all health care workers, aimed at evaluating chronic-degenerative diseases risk among three main welfare activities (medical, nursing and auxiliary). In conclusion, data showed that nurses, mainly the shift workers, are exposed to a higher risk of chronic-degenerative diseases. All other health care workers have not significant work risk factors, because of a greater burden of aging and lifestyles effects.

[Health promotion and computer science in radiation protection]. / Promozione della salute e applicazione informatica nella sorveglianza medica della radioprotezione.

An automatic system of clinical-diagnostic information has been applied to workers exposed to ionising radiation at the University of Naples Federico II with reference to the last 5 years. For every person exposed a computerized case sheet was elaborated recording clinical, biological, dosimetric and other preventive data. In the localized risk, capillaroscopic monitoring was used. This research has highlighted the role of medical surveillance in developing health promotion criteria and the planning of the interventions with the complete control of all data in real time.

[Burden of COPD on health profiles in different work activities]. / La broncopatia cronico-ostruttiva nella popolazione generale e in popolazioni lavorative.

According to WHO, COPD will be the 5th cause of disability and the 3rd cause of mortality by 2020. Even cigarette smoking represents the main cause of COPD recent studies demonstrated positive association with occupational exposure. In Europe costs of COPD were estimated at about 38,8 billion Euros in 2000; its burden is also expected to increase. Aim of the study is to evaluate the burden of COPD on health profiles in a sample of workers of Campania region. Prevalences were calculated in a sample of 908 male workers, employed in industrial (479) and tertiary (429) sectors. Results were compared with population data of ISTAT database. Higher prevalence of COPD was found in industrial workers (23.4%) than general population (3.5%) and tertiary workers (2.1%). Analysing smoking habits, higher prevalence of smokers in the industrial sector (75.9%) than tertiary (66.4%) was found, but this difference cannot explain the big difference of COPD prevalence between the two groups and suggest a positive interaction between smoking and occupational exposure. In conclusion, the results analysis underlines the burden of COPD on workers' health status, particularly in some work activities. Specific health promotion programs are necessary in these activities.

Cutaneous vasculitis: diagnosis and management.

Vasculitis is histologically defined as inflammatory cell infiltration and destruction of blood vessels. Vasculitis is classified as primary (idiopathic, eg, cutaneous leukocytoclastic angiitis, Wegener's granulomatosis) or secondary, a manifestation of connective tissue diseases, infections, adverse drug eruptions, or a paraneoplastic phenomenon. Cutaneous vasculitis, manifested as urticaria, purpura, hemorrhagic vesicles, ulcers, nodules, livedo, infarcts, or digital gangrene, is a frequent and often significant component of many systemic vasculitic syndromes such as lupus or rheumatoid vasculitis and antineutrophil cytoplasmic antibody-associated primary vasculitic syndromes such as Churg-Strauss syndrome. In most instances, cutaneous vasculitis represents a self-limited, single-episode phenomenon, the treatment of which consists of general measures such as leg elevation, warming, avoidance of standing, cold temperatures and tight fitting clothing, and therapy with antihistamines, aspirin, or nonsteroidal anti-inflammatory drugs. More extensive therapy is indicated for symptomatic, recurrent, extensive, and persistent skin disease or coexistence of systemic disease. For mild recurrent or persistent disease, colchicine and dapsone are first-choice agents. Severe cutaneous and systemic disease requires more potent immunosuppression (prednisone plus azathioprine, methotrexate, cyclophosphamide, cyclosporine, or mycophenolate mofetil). In cases of refractory vasculitis, plasmapheresis and intravenous immunoglobulin are viable considerations. The new biologic therapies that work via cytokine blockade or lymphocyte depletion such as tumor alpha inhibitor infliximab and the anti-B-cell antibody rituximab, respectively, are showing benefit in certain settings such as Wegener's granulomatosis, antineutrophil cytoplasmic antibody-associated vasculitis, Behçet's disease, and cryoglobulinemic vasculitis.

Prospective clinical evaluation of patients from Missouri and New York with erythema migrans-like skin lesions.

BACKGROUND: The most common and most recognizable feature of Borrelia burgdorferi infection (Lyme disease) is the skin lesion erythema migrans (EM). An illness associated with an EM-like skin lesion, but which is not caused by B. burgdorferi, occurs in many southern states in the United States (southern tick-associated rash illness [STARI], also known as Masters disease). METHODS: Clinical features of 21 cases of EM-like skin lesions in 21 patients from Missouri were compared in a prospective study with those of 101 cases in 97 patients with EM-like skin lesions from New York. RESULTS: Among Missouri cases, the peak incidence of EM-like skin lesions occurred earlier in the year than it did among New York cases (P<.001). Case patients from Missouri were more likely to recall a tick bite than were case patients from New York (85.7% and 19.8%, respectively; P<.001), and the time period from tick bite to onset of the skin lesion was shorter among Missouri case patients (6.1+/-4.2 days and 10.4+/-6.1 days, respectively; P=.011). Missouri case patients were less likely to be symptomatic than were New York case patients (19.0% and 76.2%, respectively; P<.001), and Missouri case patients were less likely to have multiple skin lesions (4.8% and 26.7%, respectively; P=.042). EM-like lesions in Missouri cases were smaller in size than those in New York cases (8.3+/-2.2 cm and 16.4+/-11.5 cm, respectively; P<.001), more circular in shape (P=.004), and more likely to have central clearing (76.2% and 21.6%, respectively; P<.001). After antibiotic treatment, Missouri case patients recovered more rapidly than did New York case patients (P=.037). CONCLUSION: Cases of EM-like skin lesion in patients from Missouri and New York have distinct clinical presentations.

Brief communication: hematogenous dissemination in early Lyme disease.

BACKGROUND: Bloodstream invasion in Lyme disease has been difficult to study because until recently blood culture methods were too insensitive to detect spirochetemia. OBJECTIVE: To evaluate the clinical and laboratory features of spirochetemic patients. DESIGN: Cross-sectional study. SETTING: Lyme Disease Diagnostic Center in Valhalla, New York, 1997 to 2002. PATIENTS: 213 untreated adults with erythema migrans. INTERVENTION: Blood culture for Borrelia burgdorferi. MEASUREMENTS: Symptom scores and selected laboratory measures. RESULTS: Spirochetemia was found in 93 (43.7%) patients. Spirochetemic patients were more often symptomatic (89.2% vs. 74.2%; P = 0.006) and more often had multiple erythema migrans lesions (41.9% vs. 15.0%; P < 0.001) than patients without spirochetemia. However, 8 (22.9%) of the 35 asymptomatic patients with a single skin lesion nevertheless had a positive blood culture. Risk for spirochetemia was present the day the patient noticed the lesion and continued for more than 2 weeks. LIMITATIONS: Long-term outcome data were not available. CONCLUSIONS: The high rate, early onset, and prolonged duration of risk for spirochetemia explain why untreated patients with erythema migrans are at risk for dissemination of B. burgdorferi to anatomic sites beyond the lesion site. Differences in the strain of the infecting spirochete, as well as host factors, may be important determinants of hematogenous dissemination.

Long-term follow-up of patients with culture-confirmed Lyme disease.

PURPOSE: To determine the long-term outcome of patients with culture-confirmed Lyme disease. METHODS: We analyzed data collected prospectively on adult patients from a highly endemic area in New York State who were diagnosed with early Lyme disease between 1991 and 1994. Patients with culture-confirmed erythema migrans were evaluated at baseline, 7 to 10 days, 21 to 28 days, 3 months, 6 months, 1 year, and annually thereafter. All patients were treated with antibiotics at the time of diagnosis. RESULTS: We evaluated 96 cases on 709 separate occasions (median, eight evaluations per case). The erythema migrans rash resolved within 3 weeks in all of the 94 evaluable cases, none of whom developed an objective extracutaneous manifestation of Lyme disease. Of the 81 cases who were followed for >/=1 year, all but 8 (10%) were asymptomatic at their last visit, a mean (+/- SD) of 5.6 +/- 2.6 years into follow-up, and only 3 (4%) were symptomatic at every follow-up visit. Intercurrent tick bites were reported by 45 cases (47%), and 14 (15%) developed a second episode of erythema migrans. Four other cases who were asymptomatic seroconverted between years 2 and 5. CONCLUSION: The long-term outcome of patients with erythema migrans after antibiotic therapy was excellent, but patients from a highly endemic area in New York State remained at high risk of re-exposure to ticks and reinfection. Subjective symptoms during follow-up evaluations tended to be mild to moderate, intermittent, and associated with more symptomatic illness at the time of initial diagnosis.

Laboratory diagnostic techniques for patients with early Lyme disease associated with erythema migrans: a comparison of different techniques.

Recently, a number of refinements in diagnostic modalities for detection of Borrelia burgdorferi infection have been developed. These include large-volume blood cultures, quantitative polymerase chain reaction (PCR) techniques, and 2-stage serologic testing. In the present study, we compared 6 diagnostic modalities in 47 adult patients who had a clinical diagnosis of erythema migrans. Quantitative PCR on skin biopsy-derived material was the most sensitive diagnostic method (80.9%), followed by 2-stage serologic testing of convalescent-phase samples (66.0%), conventional nested PCR (63.8%), skin culture (51.1%), blood culture (44.7%), and serologic testing of acute-phase samples (40.4%). Results of all assays were negative for 3 patients (6.4%). We conclude that the clinical diagnosis of erythema migrans is highly accurate in an area where B. burgdorferi is endemic if it is made by experienced health care personnel, but some patients with this diagnosis may not have B. burgdorferi infection. No single diagnostic modality is suitable for detection of B. burgdorferi in every patient with erythema migrans.

Association of specific subtypes of Borrelia burgdorferi with hematogenous dissemination in early Lyme disease.

To investigate whether genetic diversity of Borrelia burgdorferi sensu stricto may affect the occurrence of hematogenous dissemination, 104 untreated adults with erythema migrans from a Lyme disease diagnostic center in Westchester County, New York, were studied. Cultured skin isolates were classified into 3 groups by a polymerase chain reaction amplification and restriction fragment length polymorphism (RFLP) method. A highly significant association between infecting RFLP type in skin and the presence of spirochetemia was found (P<.001). The same association existed for the presence of multiple erythema migrans lesions (P=.045), providing clinical corroboration that hematogenous dissemination is related to the genetic subtype of B. burgdorferi sensu stricto. There were no significant associations between RFLP type and seropositivity or clinical symptoms and signs except for a history of fever and chills (P=.033). These results suggest that specific genetic subtypes of B. burgdorferi sensu stricto influence disease pathogenesis. Infection with different subtypes of B. burgdorferi sensu stricto may help to explain differences in the clinical presentation of patients with Lyme disease.

Retinal degeneration associated with ectopia lentis.

Two brothers had retinal degeneration, lens subluxation, and myopia since early life. There was no evidence of Marfan syndrome, homocystinuria, or other systemic disease. They had nystagmus, myopia, inferior dislocation of the lens, and posterior subcapsular opacities in both eyes. Fundus examination showed attenuated retinal vessels, macular atrophy with occasional pigment accumulation as clumps, and perivascular sleeves. Electroretinography revealed decreased photopic and scotopic responses. The visual fields were constricted. We believe this to be the first report of retinal degeneration with bilateral lens subluxation in a family. It appears to be inherited in an autosomal recessive fashion.
