Anticoagulants and cataract surgery.

To evaluate complications resulting from increased bleeding, 2,178 cataract surgery patients, 28 of whom were on anticoagulants, were studied prospectively. The anticoagulated patients showed no increase in sight-threatening complications when compared to the nonanticoagulated cataract patients.

[Management and prevention of abuse in Quebec: a program of sociolegal pediatrics at the Sainte-Justine Hospital in Montreal].

In Quebec, the Child's Protection law protects the child from birth until 18 years of age when child abuse or neglect is suspected. Since 1990, the program of the Child Protection Clinic of Sainte-Justine Hospital (Montreal) offers a special unit for evaluation and prevention of child abuse and neglect, constituted by a multidisciplinary team including five pediatricians. About 500 children are referred each year in external consultations or from hospital units. In addition, the pediatricians participate in the "programme Santé-Enfance-Jeunesse", a prevention program in the Montreal area. They also act as expert witnesses in court. Thus Quebec's pediatricians fully participate in a child's protection with their activities in different levels of diagnosis, management and prevention of child abuse and neglect.

The role of wild ruminants in the epidemiology of bovine petechial fever.

After experimental inoculation of Cytoecetes ondiri, the agent of bovine petechial fever (BPF), multiplication occurred in impala, bushbuck, Thomson's gazelles and wildebeest, as shown by infectivity studies and clinical findings. Similar attempts to infect one eland failed. As a sequel to this, blood and spleen samples were collected from four species of wild ruminants in an area where BPTF was endemic. Isolations of C. ondiri were made from three of five bushbuck, but not from any other species.

Major complications of sinus surgery: a review of 1192 procedures.

Based on this review of 1192 intranasal sinus procedures under endoscopic control with video assistance, the risk of major complications was estimated to be about 1.3 per cent. Ethmoidectomy was the most hazardous procedure. Operation by a right-handed surgeon standing on the right side of the patient was an added risk factor. We stress ways of achieving prevention, peroperative recognition of cerebrospinal fluid leaks and proper management of complications.

Autoerythrocyte sensitization (Gardner-Diamond) syndrome.

We describe the clinical presentation and course of a patient with autoerythrocyte sensitization (Gardner-Diamond) syndrome, and review the literature for similar cases. A 37-yr-old female presented with recurrent episodes of painful ecchymotic bruising over the anterior aspect of both thighs. These episodes were precipitated by emotional stress. The diagnosis was confirmed by induction of similar lesions by intradermal injection of the patient's own washed red blood cells and hemoglobin. The lesions did not recur for 6 months after the cause of her emotional stress was relieved. Autoerythrocyte sensitization (Gardner-Diamond) syndrome should be considered in the differential diagnosis of purpura, especially in patients with psychiatric problems.

Effects of ketorolac tromethamine on hemostasis in volunteers.

Ketorolac tromethamine, an analgesic agent with prostaglandin synthetase--inhibiting activity, is more active than aspirin in vitro in inhibiting collagen- or arachidonic acid-induced platelet aggregation. In this randomized, double-blind study, 26 volunteers received ketorolac, 30 mg intramuscularly four times a day for 5 days, and placebo, two capsules orally four times a day for at the last 2 study days. The effects of this treatment were compared with those of intramuscular placebo and oral aspirin, two 325 mg capsules, given on the same schedule to eight volunteers. Aspirin at a mean serum concentration of 84 micrograms/ml did not affect prothrombin time, partial thromboplastin time, platelet count, or bleeding time. Ketorolac produced a modest prolongation of the bleeding time, from 4.9 +/- 1.1 minutes (mean +/- SD) to 7.8 +/- 4.0 minutes (p less than 0.005). Ketorolac did not affect the prothrombin time or partial thromboplastin time but was associated with clinically insignificant change in the platelet count from 303 +/- 57 X 10(3)/m3 to 277 +/- 56 X 10(3)/mm3.

Low response to high-dose intravenous immunoglobulin in the treatment of acquired factor VIII inhibitor.

Prednisone is the classic first-line therapy to suppress an acquired factor VIII inhibitor and may achieve complete remission in about 30% of patients. More recently, promising results have been reported with high-dose intravenous immunoglobulin (IVIg). However, after an extensive review of the literature, we found only three complete remissions (12%) among the 26 assessable patients treated by IVIg. These data are in agreement with the low response to IVIg that we experienced in our series of patients. This study suggests that steroids should still be preferred to IVIg, an expansive therapy, to suppress an acquired factor VIII inhibitor.

Association between hyperflexibility of the thumb and an unexplained bleeding tendency: is it a rule of thumb?

A bleeding tendency manifested by petechiae and ecchymoses is one of the most common causes for referral of patients to haematology clinics. Vessel wall pathology is not usually considered to be a cause for deranged haemostasis, although coexistence of increased capillary fragility and joint hypermobility have been reported. We determined the frequency of thumb hyperextensibility and scored the findings in a series of 44 patients referred because of ecchymoses and petechiae, as well as 261 control children and their mothers. All 44 patients had normal coagulation studies. Thumb flexibility score was +4 in 30 patients, +3 in eight patients, +2 in five patients and +1 in one of the index patients. In the control group, only one of 261 had a +4, and three had a +3 score, and two of 260 mothers had a +4 score. Ecchymoses were not observed in any of these subjects, nor in the +1 patients. Based on clinical presentation and normal coagulation studies, we suggest that our patients had an underlying subtype of Ehlers-Danlos syndrome. In view of the dramatically high occurrence of thumb hyperextensibility in patients with unexplained mild bleeding tendency, costly haemostatic and coagulation studies on such patients may not be necessary.

Histopathology and microbiology of isolated rectal bleeding in neonates: the so-called 'ecchymotic colitis'.

Rectal bleeding in neonates is an alarming event which suggests a possible necrotizing enterocolitis (NEC) but is usually the only symptom of an unexplained colitis characterized endoscopically by ecchymotic mucosal lesions, the so-called 'ecchymotic colitis' (EC). We studied histologically and bacteriologically 18 infants (mean age: 18 days) presenting with rectal bleeding by systematic rectosigmoidoscopy and intestinal biopsies. The 18 infants were hospitalized. Prematurity was found in seven cases and an underlying condition in 14 cases (respiratory distress: six cases; infection: six cases; surgery: two cases). Histology showed a mild to moderate inflammation (10/12) of the mucosa with a prevalence of polymorphonuclear cells (8/10), frequent focal haemorrhages (11/12) and foci of pneumatosis (4/12). Numerous bacteria were seen in the mucus layer focally forming large clusters. Cultures of intestinal biopsies yielded exclusively Enterobacteriaceae species: Escherichia coli (seven cases), Klebsiella spp. (seven cases), and Enterobacter cloacae (three cases); four cases were sterile. Our study demonstrates that neonatal bleeding is associated with endoscopic and histological 'ecchymotic colitis' lesions and with a peculiar microbial flora of EBC strains. EC and necrotizing enterocolitis share similar features raising the question of the link between the two syndromes.

Bruising following blood donation, its management and the response and subsequent return rates of affected donors.

A study was undertaken to determine the incidence of bruising among blood donors and to analyse their response to the management of this complication. A total of 52 510 donors were bled at 476 consecutive donor sessions held by the Brentwood Centre during a 4-month period. Of these, 344 donors (0.66%) were found to have developed bruises following venepuncture. The incidence of bruising among males was 0. 35% and that among females was 0.98%. All bruised donors were managed by the Centre nursing and medical staff. One hundred and sixty-one donors informed the Centre that they were fully satisfied with the way their bruising was managed. Of 329 bruised donors who remained in the panel, 249 (75.7%) attended subsequent blood donor sessions in response to routine invitations, showing that the majority of bruised donors continued to donate blood. This response was compared with that of a control group of donors who did not develop any complications and there was no significant difference in the return rates between the two groups.

Alpha1-antitrypsin deficiency and toxic shock: a Japanese autopsy case.

A 74-year-old Japanese female presented with the sudden appearance of hemorrhagic purpuric ecchymoses on her lower extremities and with fever and chills, and died on the fifth day of hospitalization. A diagnosis of alpha1-antitrypsin (AT) deficiency was made postmortem. The liver weighed 1260 g. Histological sections from the liver revealed rather severe fatty changes of the hepatocytic parenchyma and partial loss of the normal hepatic architecture with fibrosis. The hepatocytes contained periodic acid-Schiff (PAS)-positive, diastase-resistant and alpha1-AT-positive intracytoplasmic globules. There was markedly increased inflammatory infiltration with severe edema and congestion, accompanied by fibrous, thickened pulmonary alveolar walls with fibrin deposition in the lungs (right, 410 g; left, 280 g), which suggest findings similar to those seen in multiple organ failure. Mild pulmonary emphysema was also present in the upper lobes of the lungs. Histological sections from the hemorrhagic necrotic ecchymoses of the skin showed marked neutrophil infiltration over the subcutaneous tissue with bleeding and blistering. A finding of thrombophlebitis was also found in the subcutaneous tissue. No bacteria were detected in the ecchymoses, the urine or the blood. Plasma protein analysis revealed a lower level (9.5 micromol/L) of alpha1-AT and a higher level (330 U) of anti-streptolysin O (ASO). These findings suggest that the patient died of toxic shock-like syndrome and that alpha1-AT deficiency might have facilitated the development of the toxic shock. To our knowledge, this is the first case of toxic shock associated with alpha1-AT deficiency.

Systemic symptoms associated with orbital venous vasculitis.

Orbital venous vasculitis has been suggested to cause characteristic periorbital pain in patients with pathologic changes in their orbital phlebograms. The orbital pain is characterized by being unilateral, not shifting side, boring and pressing, but not throbbing, increasing on eye strain, exposure to cold, or weather changes, and resistant to analgesics. It is ameliorated by steroids. Fifty patients with symptoms of orbital venous vasculitis were investigated for other symptoms that could be related to the vasculitis. When the 32 female patients were compared with a randomly selected age- and sex-matched control group, there was a significant increase of symptoms of chronic fatigue, cold feet, gut problems such as constipation and/or diarrhea, arthralgia, memory impairment, rotatory vertigo, spontaneous ecchymoses (all, p less than 0.0001), back pain (p less than 0.012), and thrombophlebitis (p less than 0.022) in the patient group. These symptoms, although commonly occurring, seem in these patients to be related to the vasculitis. Blood tests of the fifty patients showed signs of inflammation which did not disagree with the hypothesis of an immunologic cause of the orbital venous vasculitis.

Coagulation factors in orbital venous vasculitis.

Orbital venous vasculitis has earlier been shown to be associated with spontaneous ecchymoses. With the reservation that platelet function was not investigated and fibrinolysis only partly, this study of the coagulation factors of eight patients with orbital venous vasculitis showed normal findings, suggesting immunologic etiology rather than coagulation deficiency as the cause of the spontaneous ecchymoses.
