The unborn child is at risk from several maternal diseases and behaviors, such as smoking (tobacco and cannabis) and alcohol consumption. Other threats come from maternal infections (AIDS, hepatitis, rubella, toxoplasmosis, etc.), certain medicines, obesity, diabetes, etc. Many young women of child-bearing potential are unaware of these risks, and need to be informed well before they conceive. Healthcare professionals must be trained to provide this information, notably during preconceptional consultations. The first examination should take place during the first month of pregnancy (rather than before the third month at present), given the risks of early embryonic and fetal damage. This is not just a question of public health but also a social issue, as the lack of information is most flagrant among the poor. Everything must be done to ensure that all children have the best possible chance of growing up in good health.

Idiosyncratic generalized skin disorders resembling serious drug hypersensitivities have reportedly occurred after occupational exposure to trichloroethylene. However, factors associated with the disorders remain unknown except for trichloroethylene exposure. This study aimed at clarifying whether infectious diseases contributed to the development of rash or hepatitis in patients with trichloroethylene-related generalized skin disorders. Fifty-nine patients consecutively hospitalized between March 2002 and December 2003 and 59 healthy exposed workers selected on an age-matched basis in the patients' factories were enrolled in the study. Information on possible risk factors for rash and hepatitis was collected with structured checklists. Antibody titers were measured for hepatitis A, B and C viruses, Mycoplasma pneumoniae, herpes simplex viruses 1 and 2, Epstein-Barr virus, cytomegalovirus, human herpesvirus 6, measles and rubella virus. Thirty-six cases (59%) showed exfoliative dermatitis, 17 (28%) erythema multiforme, 4 (7%) Stevens-Johnson syndrome, and 4 (7%) toxic epidermal necrolysis. Before the onset of rash, 16 (27%) cases had received medication prescribed for the preceding fever, a main first symptom of the disorders. Marked increases in anti-human herpesvirus 6 IgG titer (> or =256), which indicated viral reactivation, were noted in 14 (25%) patients, while no abnormal increase was detected in the controls (p<0.001). Anti-measles IgM titer was positive in 2 (7%) cases but not in the controls (p=0.49). The involvement of other known risk factors of rash or hepatitis was ruled out. These results suggest that part of trichloroethylene-related generalized cutaneous disorders occurring in China and drug-induced hypersensitivity syndrome overlap in terms of human herpesvirus 6 reactivation.

With the overall increase in international travel, there is likely to be an increase in travel during pregnancy as well. In developing countries, pregnant women face exposures that can add significant risk for neonatal morbidity and mortality. Infections that can occur in utero or in the early neonatal period include malaria, yellow fever, tuberculosis, hepatitis, human immunodeficiency virus, leishmaniasis, toxoplasmosis, filariasis, Japanese encephalitis, rubella, typhoid fever, leptospirosis, dengue fever, Helicobacter pylori, and trypanosomiasis. When travel and potential exposure cannot be avoided, preventive measures are usually effective. Pretravel consultation should include careful discussion of length of travel, antimalarial prophylaxis, insect avoidance, food and water hygiene, vaccination, and body fluid precautions.

The parvovirus B 19 is part of the family of the parvoviridae and shows a distinctive tropism for erythropoid precursor cells. The virus causes in children the erythema infectiosum (German measles). Meanwhile, parvovirus B 19 infections can be associated with a wide spectrum of hematological and non-hematological complications (e.g. liver failure, hepatitis, aplastic crises primarily in association with chronic hemolytic anaemias, chronic arthritis, arthralgia/arthritis, transient/persistent anaemias, vasculitis, glomerulonephritis). Intrauterine infections can lead to specific or permanent organ defects (e.g. heart anomalies, eye diseases, micrognathy, chronic anaemia, myocarditis, hepatitis, mekonium peritonitis and central nervous system anomalies). Parvovirus B 19 infections are also associated with hydrops fetalis and intrauterine death during pregnancy. A definite relation between fetal malformations and B 19 infection has not been accomplished yet. Pregnancies complicated by parvovirus B 19 infection should be followed for further exclusion of any teratogenic effect. Although congenital malformations after a parvovirus infection are possible, this phenomenon seems to be rare. An intrauterine therapy with packed red cells could be performed for hydrops fetalis and low haemoglobin concentration. Investigation for the development and clinical testing of an efficient vaccine against parvovirus B 19 is currently in progress.

Comparative data on fetal and neonatal deaths following maternal mumps, rubella, hepatitis, chicken pox and measles were obtained in a prospective study in New York City from 1957 to 1964, inclusive. The evidence pointed to an increase in early fetal death rate after rubella and mumps and an increase in perinatal mortality after rubella and hepatitis. A significant increase in these rates was not demonstrable for chicken pox and measles in the selected population studied and under the conditions of the present study. The lethal effects of maternal virus diseases were demonstrable in cases of mumps and rubella occurring in the early weeks of gestation and in cases of hepatitis occurring in the late weeks of pregnancy. Fetal death was attributable to severity of maternal disease in hepatitis and to early infection of the fetus in rubella. Other factors related to gonadal infection and to placental and hormonal changes early in pregnancy may be influential in the lethal effect of mumps. Maternal and fetal death occurred in single cases of chicken-pox pneumonia and hepatitis.

A 23-year-old woman presented to our polyclinic complaining of itching, generalized dermatitis, and jaundice. She was in her 31st gestational week and had developed pruritus and the dermatitis since the first month of pregnancy; her jaundice started about a month before presentation. Her history included similar complaints in a previous pregnancy, which resulted in premature birth of a baby with a permanent brain defect. One of her sisters had had jaundice and itching in her 27th gestational week and delivered a healthy baby; a second sister had experienced itching and dermatitis in her second trimester and delivered a healthy baby. Physical examination of the patient showed that her eyes were jaundiced (Figure 1); skin examination revealed generalized erythematous excoriated papules, symmetrically distributed all over her body (Figure 2 Figure 3). Laboratory analyses revealed the following results: leukocyte count, 14.30/mm(3) (3.8-10.3/mm(3)); erythrocyte sedimentation rate, 25 mm/h (<20 mm/h); aspartate aminotransferase, 44 U/L (5-40 U/L); alanine aminotransferase, 63 U/L (5-40 U/L); lactate dehydrogenase, 1158 U/L (220-450 U/L); total bilirubin, 6.88 mg/dL (<1.10 mg/dL); and direct bilirubin, 3.27 mg/dL (<0.35 mg/dL). Urinalysis results were positive for bilirubin and urobilinogen. Positive serologic findings included rubella immunoglobulin G, 93 AU/mL (<15) and cytomegalovirus, 188 AU/mL (<10); negative findings included herpes simplex virus type 2 and hepatitis. Histopathologic examination of material collected from the left breast via punch biopsy showed parakeratosis, acanthosis, and perivascular lymphocyte infiltration in dermal vessels. Treatment with 2 g/d cholestyramine and a topical corticosteroid was effective in the patient, who was diagnosed with intrahepatic cholestasis of pregnancy and prurigo of pregnancy based on the clinical, histopathologic, and laboratory findings. To the authors' knowledge, this is the first such reported case in the literature.

Viral infection of the liver can lead to severe tissue damage when high levels of viral replication and spread in the organ are coupled with strong induction of inflammatory responses. Here we report an unexpected correlation between the expression of a functional X domain encoded by the hepatotropic mouse hepatitis virus strain A59 (MHV-A59), the high-level production of inflammatory cytokines, and the induction of acute viral hepatitis in mice. X-domain (also called macro domain) proteins possess poly-ADP-ribose binding and/or ADP-ribose-1''-phosphatase (ADRP) activity. They are conserved in coronaviruses and in members of the "alpha-like supergroup" of phylogenetically related positive-strand RNA viruses that includes viruses of medical importance, such as rubella virus and hepatitis E virus. By using reverse genetics, we constructed a recombinant murine coronavirus MHV-A59 mutant encoding a single-amino-acid substitution of a strictly conserved residue that is essential for coronaviral ADRP activity. We found that the mutant virus replicated to slightly reduced titers in livers but, strikingly, did not induce liver disease. In vitro, the mutant virus induced only low levels of the inflammatory cytokines tumor necrosis factor alpha and interleukin-6 (IL-6). In vivo, we found that IL-6 production, in particular, was reduced in the spleens and livers of mutant virus-infected mice. Collectively, our data demonstrate that the MHV X domain exacerbates MHV-induced liver pathology, most likely through the induction of excessive inflammatory cytokine expression.

A 24-year-old man was referred to our clinic in August 2003 with complaints of weakness, dizziness, and bilateral knee pain of 3 years' duration. Bilateral digital clubbing had been found on routine physical examination during his military service 4 years earlier. There were no cardiorespiratory or abdominal symptoms. There was no compromise in the activities of everyday life. The patient was not a chronic smoker. In the family history of the patient, his brother had been diagnosed with pachydermoperiostosis in another center 2 years earlier, but did not return to the hospital for a follow-up investigation of myelofibrosis. On physical examination, the patient showed marked drumstick clubbing of the hands (Fig. 1), and a pale general appearance. The causes of digital clubbing are shown in Table 1 (Fawcett RS, Linford S, Stulberg DL. Nail abnormalities: clues to systemic disease. Am Fam Physician 2004; 69: 1417-1424). Deep nasolabial folds were seen on the face. Skin hypertrophy, cutis verticis gyrata, and seborrhea on the face were also observed. The patient also complained of hyperhidrosis. Examination of the cardiovascular system was normal. There was bilateral swelling of the ankle and knee (Fig. 2). Hepatosplenomegaly was found on abdominal examination. Investigations showed hypochromic microcytic anemia [hemoglobin, 8.58 g/dL (normal, 12.2-18.1 g/dL); hematocrit, 28.1% (normal, 37.7-53.7%); white blood cell count, 3430/mm(3) (normal, 4600-10,200/mm(3)); neutrophils, 2470/mm(3) (normal, 2000-6900/mm(3)); lymphocytes, 820/mm(3) (normal, 600-3400/mm(3)); platelets, 162,000/mm(3) (normal, 142,000-424,000 mm(3)); mean corpuscular volume, 73.7 fL (normal, 80-97 fL)]. Anisocytosis, poikilocytosis, microcytosis, and hypochromia were observed on peripheral blood examination, and the erythrocyte sedimentation rate was 37 mm/h. The serum C-reactive protein level was 50.1 mg/L (normal, 0-5 mg/L). Biochemical parameters, including serum calcium, phosphate, alkaline phosphates and liver function tests, were found to be within the normal range. The causes of secondary hypertrophic osteoarthropathy associated with pulmonary, rheumatologic, endocrine, cardiac, and gastroenterologic disorders were excluded. Growth hormone level and thyroid function tests were normal. Antinuclear antibody, TORCH [Toxoplasma immunoglobulin M (IgM), rubella IgM, cytomegalovirus IgM, herpes simplex IgM] panel, and markers of hepatitis were negative. Serum Igs and rheumatoid factor were found to be within the normal range. There was subperiosteal new bone formation on bilateral knee X-ray (Fig. 3). Radiography of the chest, pulmonary function tests, arterial blood gas, and echocardiography were normal. Abdominal ultrasonography revealed hepatosplenomegaly. Amyloid deposition was not determined in rectal biopsy. Reticulin-type myelofibrosis was found on bone marrow biopsy (Figs 4 and 5). In the cytogenetic study, monosomy 22 was detected in four of 20 metaphase plates.

About 20 species from Callicarpa have reported ethnobotanical and ethnomedical uses, and several members of this genus are well known in the traditional medical systems of China and South Asia. Ethnomedical reports indicate their use in the treatment of hepatitis, rheumatism, fever, headache, indigestion, and other ailments. Several species of Callicarpa have been reported to be used against cancer (e.g., Callicarpa americana root to treat skin cancer and Callicarpa rubella bark to treat tumors of the large intestine). Extracts from about 14 species in this genus have been evaluated for biological activity, including antibacterial, antifungal, anti-insect growth, cytotoxic, and phytotoxic activities. In addition to amino acids, benzenoids, simple carbohydrates, and lipids, numerous diterpenes, flavonoids, phenylpropanoids, phytosterols, sesquiterpenes, and triterpenes have been detected in or isolated from the genus Callicarpa. The essential oils of Callicarpa americana have recently been reported to have antialgal and phytotoxic activities, and several isolates from this species (and C. japonica) were identified as contributing to the mosquito bite-deterrent activity that was first indicated by folkloric usage. Recent bioassay-guided investigations of C. americana extracts have resulted in the isolation of several active compounds, mainly of the clerodane diterpene structural type.

The health background management and outcomes of 5 pregnancies in 4 women affected by Cooley Disease, from Paediatric Institute of Catania University, are described, considering the preconceptual guidances and cares for such patients. These patients were selected among a group of 100 thalassemic women divided into three subgroups, according to their first and successive menstruation characteristics: i) patients with primitive amenorrhoea, ii) patients with secondary amenorrhoea and iii) patients with normal menstruation. Only one woman, affected by primitive amenorrhoea, needed the induction of ovulation. A precise and detailed pre-pregnancy assessment was effected before each conception. This was constituted by a series of essays, including checks for diabetes and hypothyroidism, for B and C hepatitis and for blood group antibodies. Moreover were evaluated: cardiac function, rubella immunity and transaminases. Other pregnancy monitoring, and cares during labour and delivery were effected according to usual obstetrics practice.All the women were in labour when she were 38 week pregnant, and the outcome were five healthy babies born at term, weighting between 2600 and 3200gs. The only complication was the Caesarean section. The improvements of current treatments, especially in the management of iron deposits, the prolongation of survival rate, will result in a continuous increase of pregnancies in thalassemic women. Pregnancy is now a real possibility for women affected by such disease. We are furthermore studying the possibility to collect the fetus' umbilical cord blood, after the delivery, to attempt eterologus transplantation to his mother trying to get a complete marrow reconstitution.
