Results of emergency surgery in patients with Moschowitz's disease refractory to hematological treatment: is splenectomy always advisable?

BACKGROUND: Patients with thrombotic thrombocytopenic purpura (TTP), Moschowitz's disease, run a high risk of perioperative bleeding and need intensive hematologic support. In some patients, TTP is associated with cancer but the surgical role in these patients is still unclear. To illustrate the surgical problems and outcome we present the case histories of three patients with TTP observed in our emergency department. MATERIALS AND METHODS: Two patients had TTP secondary to cancer and one patient with primary TTP (no evidence of neoplasia) had emergency operation for gastric hemorrhage, occlusion and TTP unresponsive to plasmapheresis. RESULTS: The first two patients who had not radical resection of cancer and no splenectomy, died for TTP complications. The third patient who underwent emergency splenectomy, had an uneventful postoperative course and TTP completely regressed. CONCLUSIONS: These case reports suggest that patients with TTP should be screened to rule out cancer. In patients with acute cancer-related complications emergency surgery should aim to resect the cancer. An associated splenectomy may increase the effectiveness of postoperative hematologic therapy.

[Prevalence of group B beta-hemolytic Streptococcus colonization in a sample of 23,312 pregnant women and newborn infants].

We report the prevalence of colonization of Group B Streptococci in a given population referred to a limited area in the north-west of Italy. 23.312 pregnant women were tested. Group B Streptococci have been isolated from genital cultures in 0.18-13.2% (mean 8.18). The prevalence of Group B streptococcal colonization from ear, throat and ocular cultures of newborn infants from colonized mothers was 11.55%. Incidence of infection in neonates has varied from 0 to 2.33% (1.5 per 1000 live births).

[Pseudolithiasis caused by ceftriaxone in children: a case report].

Recently, there are in literature some reports concerning the sonographic observation of transient gallbladder precipitates in children and adults during ceftriaxone treatment. The condition is defined as ceftriaxone-reversible "pseudolithiasis" and the gallbladder precipitates resolve spontaneously after cessation of therapy. We present a case of a 1 year old children treated with ceftriaxone who presented asymptomatic pseudolithiasis that resolved partially two weeks after cessation of treatment. The sonographic observation performed four months after cessation of therapy show a normally gallbladder, without precipitates or sludge.

[Diagnostic problems in a 7-month-old boy with tubercular lobitis].

A 7-month child with pulmonary tuberculosis infection involving the whole right upper lobe is described. He was referred to us after diagnosis of recurrent asthmatic bronchitis. In spite of the severity of bronchopulmonary involvement, the outcome was good after 5 months of antitubercular chemotherapy.

[Beta-2 agonists, exposure to allergens and bronchial hyperreactivity in children with allergic asthma].

The contribution of beta 2-agonist treatment per se and the effect of beta 2-agonists plus allergen exposure was evaluated in two groups of thirteen asthmatic children being treated respectively at sea level during the period of maximal allergen exposure and at high altitude in an environment free of the offending allergens. Bronchial hyperreactivity was evaluated by standardised exercise tests before and after treatment with salbutamol controlled release tablets (4 mg). Challenges were performed at the beginning and after 2 and 4 weeks of treatment. A fourth test was performed 2 days after stopping the treatment. Children treated with salbutamol at sea level (exposure to allergen) showed baseline delta PEF of 16.9 +/- 3.4 and 13.7 +/- 4.2, 20.7 +/- 4.3, 26.0 +/- 5.1 respectively for the second, third and fourth test. Children treated at high altitude showed respectively delta PEF of 34.9 +/- 5.1, 31.1 +/- 4.9, 26.5 +/- 5.4, 27.9 +/- 5.0. These data suggest that oral salbutamol per se is not responsible for an increase in bronchial responsiveness, but eventually suggest that treatment with beta 2-agonists at the same time as continued allergen exposure may be responsible for an increase in bronchial hyperresponsiveness.

Pulmonary sclerosing hemangioma in a woman with multiple uterine fibromas, cysts to thyroid and kidney.

Pulmonary sclerosing hemangioma (PSH) is a relatively rare, homogeneous solitary tumor. Its complex histology may suggest a number of malignancies. We report one case diagnosed in a 62-years-old woman with a tendency to benign tumors (uterine fibromas) and cystes (thyroide, kidney). Bronchoscopy was normal. Pulmonary scintiscan was not done. Chest X-ray showed a 2 x 2 cm solitary, dense, homogeneous, delimited nodule of the LLL. The intraoperatory diagnosis of adenocarcinoma led to lobectomy. The final diagnosis of PSH was done on fixed and stained samples. She is in good condition after 13 months of follow-up.

Pulmonary angiodysplasia: a case report.

A case of lung angiodysplasia is reported here in. The diagnosis of this disease before surgery is difficult. The intraoperatory diagnosis of vascular disease was possible since the pulsating mass disappeared after the inflow and outflow blood vessels were selectively clamped. The abnormal placement of a venous vessel made the resection problematical. A careful anatomic and clinical study of the lesion, and the correct instrumental diagnostic approach may lead to a suitable therapeutic stategy, which respects both functional integrity and surgical radicality. The usefulness of a systematical selective clamping of the inflow and outflow blood vessels for an exact delimitation of the lesion emphasised.

[Criteria for the evaluation of neonatal pain].

The common opinion about the painful sensation in newborn and in premature baby, is that the experience of pain begins since birth. One of the difficulties in taking care of pain in neonatology is the valuation of the symptom: actually there aren't enough sensitive and standard methods to define and quantify the pain of newborns and prematures babies. The authors illustrate two scales of pain valuation, that have been tested and then adopted by different french groups. These scales allow to examine respectively, the healthy newborn and the newborn after surgical care and permit also an objective measure of newborn malaise sensation. These scores need the valuation of clinical signs and physiological parameters that are sometimes neglected during the execution of invasive techniques; therefore these tables would awaken the sanitary staff to newborn expressions of pain or discomfort, allowing a best comprehension of baby's feelings and facilitating in this nursing and pharmacological interventions to relieve pain.
