Abstract
BACKGROUND High-voltage pulses can cause hemolysis. OBJECTIVES The authors evaluated the occurrence of hemoglobinuria after pulsed-field ablation (PFA) and its impact on renal function in patients with atrial fibrillation (AF). METHODS A consecutive series of patients with AF undergoing PFA were included in this analysis. The initial patients who did not receive postablation hydration immediately after the procedure were classified as group 1 (n = 28), and the rest of the study patients who received planned fluid infusion (0.9% sodium chloride ≥2 L) after the procedure were categorized as group 2 (n = 75). RESULTS Of the 28 patients in group 1, 21 (75%) experienced hemoglobinuria during the 24 hours after catheter ablation. The mean postablation serum creatinine (S-Cr) was significantly higher than the baseline value in those 21 patients (1.46 ± 0.28 mg/dL vs 0.86 ± 0.24 mg/dL, P < 0.001). Of those 21 patients, 4 (19%) had S-Cr. >2.5 mg/dL (mean: 2.95 ± 0.21 mg/dL). The mean number of PF applications was significantly higher in those 4 patients than in the other 17 patients experiencing hemoglobinuria (94.63 ± 3.20 vs 46.75 ± 9.10, P < 0.001). In group 2 patients, no significant changes in S-Cr were noted. The group 2 patients received significantly higher amounts of fluid infusion after catheter ablation than did those in group 1 (2,082.50 ± 258.08 mL vs 494.01 ± 71.65 mL, P < 0.001). In multivariable analysis, both hydration (R2 = 0.63, P < 0.01) and number of PFA applications (R2 = 0.33, P < 0.01) were independent predictors of postprocedure acute kidney injury. CONCLUSIONS On the basis of our findings, both the number of PFA applications and postablation hydration were independent predictors of renal insult that could be prevented using planned fluid infusion immediately after the procedure.

Abstract
A man in his early 50s presented with jaundice, mild shortness of breath on exertion and dark urine. He had had coryzal symptoms 2 weeks prior to admission. Medical history included obstructive sleep apnoea and hypertension. His initial blood tests showed a mild hyperbilirubinaemia and acute kidney injury stage 1. Chest X-ray and CT pulmonary angiogram were negative for features suggestive of COVID-19. He later developed a drop in haemoglobin and repeat bloods showed markedly raised lactate dehydrogenase and positive direct antiglobulin test. These results were felt to be consistent with a haemolytic anaemia. A nasopharyngeal swab came back positive for COVID-19. We suspect the cause of his symptoms was an autoimmune haemolytic anaemia secondary to COVID-19 which has recently been described in European cohorts.

Abstract
The effect of hypothermic cardiopulmonary bypass techniques on the sickling process was evaluated in patients with sickle cell hemoglobin. It was presumed that intraoperative hemolysis, as identified by hemoglobinuria, reflected increased sickling. Data of 43 patients with sickle cell traits and 2 with sickle cell disease, who were operated on under cardiopulmonary bypass and cold cardioplegic arrest in a tertiary center from the beginning of 1995 to the end of 2004, were retrospectively analyzed. A mean nasal temperature of 30.8°C ± 2.1°C was achieved. Three patients with sickle cell trait developed intraoperative hemoglobinuria, albeit with normal surrogate values for hemolysis. However, they had significantly lower mean hemoglobin levels during cardiopulmonary bypass compared to those sickle cell patients who did not exhibit hemoglobinuria (hemoglobin, 6.0 ± 0.2 vs. 7.4 ± 0.9 g·dL−1, p < 0.01). Total drainage and blood transfusion requirements in patients with normal and sickle cell hemoglobin were similar. It was concluded that hypothermic cardiopulmonary bypass with cold cardioplegia is safe in sickle cell patients. Maintenance of adequate hemoglobin levels during cardiopulmonary bypass may be important to avoid triggering a sickling process.

Abstract
Paroxysmal nocturnal hemoglobinuria (PNH) is a non-malignant, acquired clonal hematopoietic stem cell disease that can present with bone marrow failure, hemolytic anemia, smooth muscle dystonias, and thrombosis. We present a case of a 32 year-old-female, G2P2A0 with no past medical history of any systemic illnesses who refers approximately 2 months of progressively worsening constant heartburn with associated abdominal discomfort. CBC showed leukopenia (WBC 2.9 x 103 /µL) with neutropenia (segmented neutrophils 48%), macrocytic anemia (Hgb 6.1 g/dL, hematocrit 20%, MCV,113 fL) and thrombocytopenia (platelet count 59 x 109/L). Abdomino-pelvic CT scan revealed a superior mesenterc vein thrombosis, which was treated initially with low-molecular-weight heparih for full anticoagulation. Peripheral blood flow cytometry assays revealed diminished expression of CD55 and CD59 on the erythrocytes, granulocytes and monocytes.' Paroxysmal nocturnal hemoglobinuria is a rare, clonal, hematopoietic stem-cell disorder whose manifestations are almost entirely explained by complement-mediated intravascular hemolysis. The natural history of PNH is highly variable, ranging from indolent to life-threatening. The median survival is 10 to 15 years, but with a wide range. Thrombosis is the leading cause of death, but others may die of complications of bone marrow failure, renal failure, myelodysplastic syndrome, and leukemia. Anticoagulation is only partially effective in preventing thrombosis in PNH; thus, thrombosis is an absolute indication for initiating treatment with Eculizumab. Nevertheless, bone marrow transplantation (BMT) is still the only curative therapy for PNH but is associated with significant morbidity and mortality.

Abstract
This study aimed to assess the relevance of laboratory tests in Henoch-Schönlein purpura nephritis (HSPN) classification, and determine accurate classification factors. This prospective study included 694 HSPN patients who underwent ultrasound-guided percutaneous renal biopsy (PRB). Renal specimens were scored according to International Study of Kidney Disease in Children (ISKDC) classification. Meanwhile, blood samples were immediately collected for laboratory examination. The associations between laboratory parameters and HSPN classification were assessed. Significant differences in levels of serum Th1/Th2 cytokines, immunoglobulins, T-lymphocyte subsets, complement, and coagulation markers were obtained between HSPN patients and healthy children. Interestingly, 24h urinary protein (24h-UPRO) levels and urine protein/urine creatinine ratios could determine HPSN grade IIb, IIIa, and IIIb incidences, with areas under ROC curve of 0.767 and 0.731, respectively. At 24h-UPRO >580.35mg/L, prediction sensitivity and specificity were 75.2% and 70.0%, respectively. These values became 53.0% and 82.3%, respectively, with 24h-UPRO exceeding 1006.25mg/L. At urine protein/urine creatinine > 0.97, prediction sensitivity and specificity were 65.5% and 67.2%, respectively, values that became 57.4% and 80.0%, respectively, at ratios exceeding 1.2. Cell and humoral immunity, coagulation and fibrinolytic systems are all involved in the pathogenesis of HSPN, and type I hypersensitivity may be the disease trigger of HSPN. 24h-UPRO levels and urine protein/creatinine ratios could probably forecast the pathological classification of HSPN.

Abstract
A 25-year-old man developed macroscopic haemoglobinuria after a persistent dry cough. Although chest radiograph findings were normal, since the serum antibody for Mycoplasma pneumoniae was significantly elevated, a diagnosis infection with this organism was made. Despite the absence of apparent anaemia, a marked increase in serum haemolytic markers and positive result for urine haemoglobin indicated the haemolysis of red blood cells, which was likely to have occurred secondarily to M. pneumoniae infection. Shortly after the initiation of a macrolide antibiotic, clarithromycin, the patient's haemoglobinuria completely disappeared together with a complete resolution of his respiratory symptoms. In this case, due to the lymphocyte-stimulatory nature of M. pneumoniae, an enhanced immune response, such as the production of cold agglutinins, was likely to be involved in the pathogenesis of erythrocyte haemolysis. The immunomodulatory property of clarithromycin was thought to repress the increased immunological reaction and thus enable the resolution of the urine abnormality.

Abstract
Acute haemolysis associated with mild upper respiratory tract infection was observed in a Thai boy who presented with a rapid decline in haemoglobin (Hb) levels, haemoglobinuria and evidence of intravascular haemolysis. Several possible causes giving rise to such a condition were excluded including G6PD deficiency, which is extremely common in Thailand. Subsequent haematological and molecular analyses demonstrated that the patient was homozygous for Hb Constant Spring (Hb CS/CS), an a globin haemoglobinopathy. It has been shown previously that patients with homozygous Hb CS had mild haemolytic anaemia secondary to an accumulation of alpha(CS) chains, which are toxic to red blood cell membrane cytoskeletons. Increased body temperature might induce more precipitation of this a globin variant. This report highlights the importance of Hb CS/CS as a potential predisposing cause of acute haemolysis in children that might be aggravated by acute bacterial or viral infections. This is particularly relevant for patients of Southeast Asian descent where this abnormal haemoglobin is highly prevalent.

Abstract
Intravascular hemolysis is a rare but potentially life threatening cause of red urine characterized by brisk hemolysis and release of large amounts of hemoglobin into the urine. We present an unusual case of red urine in a 20-year-old male who was subsequently diagnosed with intravascular hemolysis due to an aorto-atrial fistula. Fistula formation was likely secondary to a recently implanted atrial septal occluder, which is a reported but exceedingly rare complication of the device. We discuss the diagnostic approach to hemolytic anemia and conclude with a literature review of other cases of device associated fistula formation and hemolysis.

Abstract
The importance of previous dehydration on the production of hemoglobinuric nephrosis is substantiated. Hemoglobinuric nephrosis regularly occurred in rabbits 3 to 16 days following the injections of hemoglobin. Five of 15 animals died of fatal hemoglobinuric nephrosis; the combined kidney weight in these exceeded the weight of the kidneys of control rabbits and of those which survived. Additional observations, not previously made, are focal necrosis of the liver and pulmonary edema in some of the rabbits which died. A relationship was evident between the quantity of available fluid and the severity of the hemoglobinuric nephrosis which developed after injections of hemoglobin.

Abstract
AIMS To determine the factors responsible for poor glycaemic control in diabetes and whether any such factors are associated with likely improvement in glycaemic control. METHODS A prospective cohort study of 130 diabetic patients with poor glycaemic control (HbA(1c )> or = 10.0%) with 1-year follow-up in a teaching hospital Diabetes Clinic. Changes in HbA(1c) were measured after 1 year. RESULTS Poor glycaemic control was attributed to one of 15 possible causes. Those cases due to recent diagnosis of diabetes, inadequate treatment with diet, oral glucose-lowering agents or insulin, exacerbation of co-existent medical problems, recent stressful life-events and missed clinic appointments were all associated with significant improvement in HbA(1c) at 12 months. Patients with low mood or alcohol excess, inadequate blood glucose monitoring, poor exercise/sedentary lifestyle, refusal to take tablets or underdosing and refusal to take insulin at all or to increase the dose were all associated with continuing poor glycaemic control at 12 months. The patients were divided almost equally between the two groups. CONCLUSIONS In patients with poor glycaemic control, it is possible by simple features identified at clinic to predict which individuals are likely to show improvement in control and which will not. These findings have not been reported previously and suggest that about half of individuals with poor control will improve within our current diabetes clinic practice. Additional strategies will be required to address those individuals who are not likely to respond.

Abstract
A 54-year-old woman was scheduled for the total hip replacement. She was anesthetized with continuous epidural blockade combined with general anesthesia using oxygen, sevoflurane, and propofol. When she received her autologous blood transfusion, we noticed the obstruction of the venous line, and pushed 30 ml of blood with 10 ml syringe. However, it was difficult to return her blood through the venous line. At that time, a sudden onset of red urine without any special symptom occurred. We investigated the cause of the red urine, whether this urine is attributable to hemoglobinuria, myoglobinuria, or porphyria. According to the patient's symptoms during and after the operation, and blood as well as urine examination, a microfilter in the venous line might have led to red blood cell destruction. The filter-induced hemolysis can be life-threatening especially in a child. We conclude that the early recognition and management of reactions associated with blood transfusion is essential during the operation.

Abstract
A 57-year-old man with lung tumor was scheduled for right middle lobectomy under general anesthesia. The patient received glycerin enema 2 hours before anesthesia. Anesthesia was induced with propofol, fentanyl, ketamine and vecuronium. After the induction, urine of dark-red color was drained through the urinary catheter. Massive (3+) occult blood and few erythrocytes in the urine sediment were observed. Furthermore, blood analysis showed hemolysis with mild renal dysfunction (Cr 1.3 mg x dl(-1)). Although serum CPK and myoglobin increased, there was no apparent symptom that supported the onset of rhabdomyolysis induced by anesthetics, acute myocardial infarction or malignant hyperthermia. At this time, we noticed that blood sample taken before the induction had been hemolysed. With all the above information in mind, we suspected that the main cause of the hemoglobinuria could be the enema and the surgery was canceled. The patient made a good progress with laboratory data normalized on the 4th postanesthesia day. However, rectal ulcer developed as a possible late complication of the enema. Although it is well-known that glycerin enema could cause hemolysis, renal failure and rectal ulcer, the increase of CPK and myoglobin in serum made the diagnosis difficult from other conditions leading to rhabdomyolysis in this case.

Abstract
The incidence of diabetes type I has increased considerably in young children with an annual increase in Switzerland of 23,8% over the last ten years. The development of rapid acting and long acting analogues allowed a significant progress in treatment. Multiple daily insulin injections together with carbohydrate counting as well as continuous subcutaneous insulin infusion (CSII) improved the quality of life and led to an increased daily flexibility. The incidence of severe hypoglycaemic events has decreased at the same time metabolic control improved. The development of interstitial glucose measurement (online) coupled to the insulin pump represents a step further towards the artificial pancreas. The new therapeutic strategies of immunomodulation will hopefully lead to secondary and tertiary prevention of diabetes.

Abstract
Our way of life has led to a massive increase in the prevalence of obesity in adults and children. Therefore diabetes type 2 has also become a pediatric disease. Therapy consists above all of implementing modifications of life style such as a healthy diet and regular physical activity in order to achieve a decrease in body weight. If these measurements prove to be insufficient, medical treatments are introduced, either using metformine or insulin. The screening and treatment of complications (retinopathy, nephropathy) and comorbidities (arterial hypertension, dyslipidemia) will help to decrease mortality on the long haul.

Abstract
The purpose of this study was to evaluate the safety of cryopreserved and thawed peripheral blood stem cell (PBSC) fractionated return infusions in children. 35 children patients with malignant tumors (13 acute leukaemias, 15 neuroblastomas and 7 malignant lymphomas) received fractionated return infusions of cryopreserved stem cells after undergoing high-dose chemotherapy without or with total body irradiation. The toxicities of 70 return infusions were evaluated. All patients were mobilized by chemotherapy plus recombination human granulocyte colony-stimulating factor (rhG-CSF), and then PBSCs were collected by a separator CS-3000 plus or COBE spectra-4. The grafts were cryopreserved in 10% dimethyl sulfoxide (DMSD) and stored in liquid nitrogen. There were totally 70 PBSC transfusions. The total volume of PBSCs transfused: 190 - 420 ml (265 +/- 73 ml or 13.7 +/- 4.2 ml/kg) with a mean of (4.43 +/- 1.91) x 10(8)/kg of PBSCs, and 0.94 +/- 0.18 g/kg of DMSO. The single dose: 90 - 300 ml (132 +/- 37 ml or 6.6 +/- 5.2 ml/kg) with a mean of 0.68 +/- 0.12 g/kg of DMSO. Symptoms occurring during the infusions were recorded. All patients were monitored for 24 hours after infusion. Pulse, blood pressure, body temperature, and respiratory rate were recorded every 15 minutes. At four hours before and 8 hours after infusion, urinalysis was performed. Serum potassium, sodium, creatinine, total bilirubin, aspartate amino transferase (AST), and alanine amino transferase (ALT) levels were examined within 24 hours before and after the first infusion. The results showed that the toxicities observed included hemoglobinuria in 54 return infusions (77.1%), headache in 28 (40.0%), nausea in 24 (34.3%), vomiting in 17 (24.3%), and abdominal pain in 8 (11.4%). Patients who received a graft > 200 ml tended to have a higher frequency of hemoglobinuria, headache, nausea, vomiting, or abdominal pain (P<0.01), and they disappeared quickly, too. Total bilirubin increased after the first return infusion (P<0.01), and there was a significant correlation between the volume of infusion and the degree of total bilirubin increase (r=0.8977, P<0.01). No renal failure or shock occurred. It is concluded that transient hemoglobinuria, headache, nausea, vomiting, and abdominal pain are common toxicities associated with PBSC autograft, and these toxicities are related with a single volume of PBSCs transfused. Total bilirubin increase is correlated with the volume of infusion. In a word, the toxicity is less frequent and lower severe in children with fractionated infusions of cryopreserved peripheral blood stem cell.

Abstract
A 56-year-old man underwent replacement of the ascending aorta with a sutureless intraluminal graft, for a Stanford type A aortic dissection. Eight years after the operation, he developed gross hemoglobinuria, associated with an intravascular hemolytic anemia. Due to numerous schistocytes in the peripheral blood, the hemolysis was attributed to mechanical injury of the red blood cells at the site of the vascular graft. The patient's course was complicated by an infection of the aortic graft, which led to an urgent graft replacement. The hemolytic anemia resolved completely shortly after the reoperation. Physicians should consider this etiology in the differential diagnosis of fragmentation hemolytic anemia.

Abstract
The aim of this study was to analyse the clinical and evolutive aspects of severe malaria in hospitalised children in 2000, 2001, and 2002 in Togo. The study included 361 children in the pediatrics department of Lomé-Tokoin University hospital. All them received a 10% dextrose infusion, then an infusion of quinine or intramuscular artemether. Malaria accounted for 4.37% of all hospitalizations. Children aged 1 to 5 years were more affected (69.53%). The most frequent clinical forms were anaemia (55.7%) followed by cerebral manifestations. The frequency of hemoglobinuria increased (17.2%) as well as renal failure (3%) compared to previous years. Thirty-five children died (9.7%). Most of them presented with anaemia, neurological manifestations, or respiratory distress. Neurological sequels were present in 2.2% of patients.

Abstract
An 11-year-old male presented with fever, rash, and a necrotic lesion on the lobule of the left ear. The lesion became tender and formed an eschar over 4 days. The patient developed leukocytosis, hemolytic anemia, and proteinuria, and was diagnosed with systemic loxoscelism from a brown recluse spider bite. He was managed with supportive therapy and improved in 4 days. Loxoscelism is a clinical diagnosis which should be suspected in an otherwise healthy patient with a necrotic wound, particulary in the endemic Southern and Midwestern United States. Physicians should be aware of this disease entity and its complications.

Abstract
Diabetic neuropathy is a common complication of diabetes mellitus. Effective blood glucose control retards changes in nerve conduction velocity in type 1 diabetes. This study examined the relationship between glycemic control and electrophysiologic changes in diabetic neuropathy in 57 type 2 diabetic patients. Nerve conduction in the peroneal motor nerve, tibial motor nerve, and sural nerve were measured at study entry and at follow-up 24+/-3.12 months later. Changes in individual nerves are expressed as a percentage change (PC) and overall electrophysiologic changes are expressed as the sum of individual PCs. The PCs for peroneal motor nerve velocity, tibial motor nerve velocity, and sural nerve velocity were all lower in patients with a mean HbA1c of 8.5% or less compared with those in patients with a mean HbA1c of more than 8.5%, and SPCV (sum of PC in velocity) was significantly inversely correlated with mean HbA1c. However, there was no significant difference in SPCV in subjects with or without hypertension, hypertriglyceridemia, or low high-density lipoprotein cholesterol concentration. In conclusion, hyperglycemia is the most important etiology for electrophysiologic progression in type 2 diabetic patients. Furthermore, a mean HbA1c of more than 8.5% will result in significant deterioration in electrophysiology.

Abstract
Sclerotherapy with absolute ethanol and/or polidocanol is a well-established therapeutic modality for the treatment of peripheral vascular malformations, although systemic complications such as hemoglobinuria and pulmonary embolism could occur. We report two cases of pulmonary embolism associated with sclerotherapy for peripheral vascular malformations. Two patients, a 17-year-old man and a 17-year-old woman, undergoing absolute ethanol sclerotherapy for vascular malformations of the leg developed pulmonary embolism after injection of ethanol. Pulmonary embolism, suspected by the clinical symptoms such as hypoxia and hypocapnia, was confirmed by the pulmonary scintigraphy showing minimal pulmonary defects. Hemoglobinuria was also observed with injection of ethanol. Patients recovered rapidly with heparin and urokinase therapy. The review of perioperative complications with sclerotherapy for peripheral vascular malformations in our institution for past four years revealed that complications were observed in 18 out of 88 patients (20.5%), and in 32 out of 183 cases (17.5%). Major complications were hemoglobinuria, pulmonary embolism, shivering and delayed emergence from general anesthesia. We conclude that sclerotherapy for vascular malformations under general anesthesia is a risky procedure and this must be carefully managed with keen monitoring of Spo2 and Etco2.

Abstract
OBJECTIVE Alloimmunization in patients with sickle cell disease (SCD) has a reported incidence of 5% to 36%. One complication of alloimmunization is delayed hemolytic transfusion reaction/hyperhemolysis (DHTR/H) syndrome, which has a reported incidence of 11%. In patients with SCD, clinical findings in DHTR/H syndrome occur approximately 1 week after the red blood cell (RBC) transfusion and include the onset of increased hemolysis associated with pain and profound anemia. The hemoglobin (Hb) often drops below pretransfusion levels. In many reported adult cases, the direct antiglobulin test (DAT) remains negative and no new alloantibody is detected as the cause for these transfusion reactions. To date, few pediatric cases have been reported with this phenomenon. The objective of this study was to describe the clinical and laboratory findings of a case series in children who had SCD and experienced a DHTR/H syndrome at our institution. METHODS An 11-year retrospective chart review of patients with discharge diagnosis of SCD and transfusion reaction was performed. DHTR/H syndrome was defined as the abrupt onset of signs and symptoms of accelerated hemolysis evidenced by an unexplained fall in Hb, elevated lactic dehydrogenase, elevated bilirubin above baseline, and hemoglobinuria, all occurring between 4 and 10 days after an RBC transfusion. Patient characteristics, time from transfusion, symptoms, reported DAT, new autoantibody or alloantibody formation, laboratory abnormalities, and complications were recorded. Patients with acute transfusion reactions were excluded. RESULTS We encountered 7 patients who developed 9 episodes of DHTR/H syndrome occurring 6 to 10 days after RBC transfusion. Each presented with fever and hemoglobinuria. All but 1 patient experienced pain initially ascribed to vaso-occlusive crisis. The DAT was positive in only 2 of the 9 episodes. The presenting Hb was lower than pretransfusion levels in 8 of the 9 events. Severe complications were observed after the onset of DHTR/H: acute chest syndrome, n = 3; pancreatitis, n = 1; congestive heart failure, n = 1; and acute renal failure, n = 1. CONCLUSIONS DHTR/H syndrome occurs in pediatric SCD patients, typically 1 week posttransfusion, and presents with back, leg, or abdominal pain; fever; and hemoglobinuria that may mimic pain crisis. Hb is often lower than it was at the time of original transfusion, suggesting the hemolysis of the patient's own RBCs in addition to hemolysis of the transfused RBCs; a negative DAT and reticulocytopenia are often present. Severe complications including acute chest syndrome, congestive heart failure, pancreatitis, and acute renal failure were associated with DHTR/H syndrome in our patients. DHTR/H in the pediatric sickle cell population is a serious and potentially life-threatening complication of RBC transfusion. It is important to avoid additional transfusions in these patients, if possible, because these may exacerbate the hemolysis and worsen the degree of anemia. DHTR/H syndrome must be included in the differential of a patient who has SCD and vaso-occlusive crisis who has recently had a transfusion.

Abstract
Radiofrequency ablation is a safe and effective treatment for small primary or secondary liver tumors. Development of new probes has allowed the use of radiofrequency ablation for ablation of tumors > 5 cm in the liver. We present a case of acute intravascular hemolysis and hemoglobinuria during radiofrequency ablation of a large 8-cm hepatocellular carcinoma via laparotomy. The hemolysis was recognized during the operation by change of urine color, and prompt management was initiated to prevent acute renal failure. Literature search revealed that radiofrequency ablation can induce hemolysis in experimental setting, but this is the first clinical report of acute hemolysis during radiofrequency ablation for liver tumors.

Abstract
Autoimmune haemolytic anaemia (AHA) is one of the commonest autoimmune disorders of man. It is characterised by the binding of anti-erythrocyte autoantibodies to red blood cells and destruction of the coated cells in the reticulo-endothelial system. Autoimnmune disorders are said to be rare in indigenous African population, probably due to the widespread infectious diseases, which impair host's T-cell immunity. This study is therefore aimed at investigating the pattern of presentation and management outcome of patients with AHA seen over a period of 10 years (June 1988 to May 1998) at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife. We retrospectively analysed the records of patients with respect to the clinical, haematological, biochemical and serological features of AHA seen within the study period. Diagnosis was based on laboratory features of haemolytic anaemia and/or a positive direct anti-human globulin (Coombs') test after excluding other causes of haemolytic anaemia. Treatment protocol and outcome were noted in all cases. We identified 13 patients with AHA (7 females, 6 males) aged 6-70 (median, 42) years. Six (42%) had secondary AHA and the remaining 8 presented with primary (idiopathic) AHA. Laboratory evidence of haemolysis (bone marrow erythroid hyperplasia and hyperbilirubinaemia) was found in all cases, while the direct Coomb's test was positive in 10 (76.9%) cases. All the patients had moderate-severe anaemia within the course of the disease, requiring blood transfusion. Remission was induced with prednisolone in all except three cases with secondary AHA who died of the primary disease before AHA could be controlled. Follow-up period post-remission ranged between 1 and 78 months. However, 2 (20%) are still being followed-up till the time of this report. This study agrees with the view that autoimmune disorders are not common in Nigerians, as documented for other Africans. It also shows that steroid therapy (prednisolone) is quite effective, especially, in idiopathic AHA, and that red cell transfusion could be useful in life-threatening anaemia.

Abstract
Two adult cases of relatively large patent ductus arteriosus (PDA) were treated by coil embolization, but were complicated by hemolysis that was successfully managed by medical treatment. Case 1 was a 67-year-old woman and Case 2 was a 71-year-old woman with a PDA of minimal diameter of 5.3 mm and 5.5 mm, respectively. The approach was via the pulmonary artery and 2 coils were delivered simultaneously into the ductus, known as the 'kissing coil technique'. Although immediately after the procedure only a small residual shunt was revealed by aortogram, hemolysis occurred for several hours after the procedure in both cases. A hemolytic complication usually needs additional coil embolization or surgical treatment, but in these 2 cases it was successfully treated by haptoglobin infusion to prevent nephropathy and by antiplasmin infusion to promote thrombus formation. Hemolytic complications of coil embolization of PDA can managed by medication when the residual shunt is minimal and the degree of hemolysis is mild.

Abstract
OBJECTIVES To retrospectively evaluate the safety and efficacy of percutaneous sclerotherapy with polidocanol in 9 patients with venous malformations of the glans penis. Vascular malformations of the external genitalia can be aesthetically and functionally disabling. These lesions are rare and their treatment is still controversial. METHODS Seven patients were asymptomatic, seeking advice for cosmetic reasons, and 2 patients had experienced several bleeding episodes during sexual intercourse. In all patients, Doppler ultrasound scanning was performed before treatment. All patients underwent direct intralesional injection of polidocanol. The concentration of the sclerosant varied from 1% to 3%, and the volume of the solution varied from 2 to 4 mL per injection. Four patients required multiple sclerotherapeutic sessions. RESULTS All patients experienced marked swelling after the injection and three developed cutaneous blistering. Neither cutaneous necrosis nor early or late major complications occurred. At a mean follow-up of 35.1 months, 7 patients were cured and 2 had marked improvement. No patients presented with signs of recurrence, and the outcome was overall cosmetically successful. CONCLUSIONS Sclerotherapy with polidocanol is a well-tolerated, safe, and effective treatment for venous malformations of the penis. In our opinion, it can be considered the treatment of choice.

Abstract
A 39-year-old woman arrived to the emergency department complaining of a constant, progressive, left flank pain, with no beneficial effect from spasmolytic and nonsteroidal antiinflammatory drugs. Two years before, she suffered another episode of right flank pain and stranguria, but instrumental examinations (ultrasonography, urography) remained negative. Besides a mild tenderness in the left flank, physical examination was normal. Blood chemistry panel showed leukocytosis (17.2 x 10(3) mL, neutrophils 82.8%) and a slight increase of serum lactate dehydrogenase (LDH) (543 U/L versus 230 to 460 U/L). Urinanalysis showed a slight hemoglobinuria (0.5 mg/dL), and sediment contained some red cells and leukocytes. Diagnostic examinations (ultrasonography, computed tomography) showed a left renal nonhomogeneous space-occupying lesion, orientative for renal malignancy. She was transferred to the urology department and operated. Both intraoperatory and histological diagnosis was ischemic infarction and, after exclusion of all possible underlying causes, final diagnosis was idiopathic renal infarction. Diagnostic procedures and literature reports are discussed.

Abstract
We entered the 20th century with only meager understanding of the erythrocyte. We leave this century with a relatively detailed understanding of the metabolism of the erythrocyte, the structure of its membrane, and the basis of genetic disorders that lead to its early demise in hemolytic anemia. Among the immune hemolytic disorders, the conquest of Rh hemolytic disease is one of the important clinical achievements of this century. Hereditary disorders of the membrane generally cause shape changes, such as spherocytosis or ovalocytosis. Paroxysmal nocturnal hemoglobinuria is the result of an acquired (somatic) mutation of PIG-A, an X-linked component of the glycosylphosphatidylinositol (GPI) anchor. Red cell enzyme deficiencies cause hereditary nonspherocytic hemolytic anemia. The mutations that cause the more common of these deficiencies are now well understood at the DNA level. Although much progress has been made, much is still to be learned. In particular, management of both acquired and hereditary hemolytic anemias is still very unsatisfactory. Often the only decision that can be made is whether to perform a splenectomy. In the future it is to be hoped that the knowledge that has been gained about these disorders in this century will make available better therapy to our patients in the next.

Abstract
OBJECTIVES To describe the incidence and management of haemolysis after transcatheter coil occlusion of the arterial duct. DESIGN Prospective clinical and echocardiographic follow up of patients who have undergone implantation of the Cook detachable duct occlusion coil. SETTING Tertiary paediatric cardiac centre. PATIENTS Five cases of haemolysis (two girls aged 6 and 11 months; three boys aged 6, 17, and 14 months) from a series of 137 duct coil implantations. MAIN OUTCOME MEASURES The occurrence of clinically significant haemolysis after implantation of duct occlusion coils and resolution of haematuria after completion of duct occlusion. RESULTS Haemolysis was detected in five of 137 procedures following implantation of Cook detachable duct coils. Four patients became symptomatic 12 hours after the procedure but in one haemolysis was detected three months later. Resolution of ongoing haemolysis was achieved within 48 hours of detection with further coil implantations, but haematuria persisted for up to 10 days. In one patient the extensive destruction of erythrocytes resulted in acute renal failure requiring peritoneal dialysis. CONCLUSIONS Haemolysis is an important complication after duct coil implantation. It occurred in 3.6% of 137 procedures in this series and is most likely to occur in young patients with relatively large ducts. Further coil implantation to occlude the duct completely is not only successful but technically relatively straightforward and should be undertaken early if major complications such as severe anaemia and renal failure are to be avoided.

Abstract
OBJECTIVE To compare results of laboratory tests in dogs with vena caval syndrome before and after surgical removal of heartworms. DESIGN Longitudinal uncontrolled clinical trial. ANIMALS 51 dogs with vena caval syndrome. PROCEDURE Heartworms were removed from the area of the tricuspid valve and pulmonary arteries via venotomy and by use of flexible alligator forceps. Blood samples were obtained before and 10 days after removal of heartworms. Red and white blood cell counts were determined, using an automated cell counter. Biochemical tests were performed, using a dry chemical method. RESULTS 45 dogs survived the procedure, and 6 died or were euthanatized after surgical treatment. After surgery, RBC count and total protein, albumin, calcium, and sodium concentrations increased, and total bilirubin, ammonia, BUN, creatinine, uric acid, and potassium concentrations decreased in dogs that survived. Creatine kinase, L-lactate dehydrogenase, and amylase activities decreased, whereas alkaline phosphatase and gamma-glutamyltransferase activities and total cholesterol concentration increased. Alanine transaminase activity decreased in 27 dogs but increased in 3 dogs. Changes in test results in dogs that did not survive. Significant differences were found in RBC count, gamma-glutamyltransferase activity, and total protein, total cholesterol, BUN, and total bilirubin concentrations before and after removal of heartworms. CLINICAL IMPLICATIONS Hepatic and renal functions improve rapidly after surgical removal of heartworms, presumably because general and pulmonary circulation is normalized. However, cholestasis may develop, and dogs that survive may need additional treatment to preserve hepatic function.

Abstract
Haemoglobinuria and periumbilical discoloration (also known as Cullen's sign) are clinical signs uncommonly reported in veterinary patients. This report describes a case of retroperitoneal haemorrhage in a dog, associated with haemoglobinuria and Cullen's sign. To the authors' knowledge, these clinical signs have not previously been reported singularly or in combination with retroperitoneal haemorrhage in dogs. A neutered male Shetland sheepdog, which was presented for haematuria, also had an abdominal mass, abdominal pain and a large area of periumbilical discoloration. Laboratory studies determined that haemoglobinuria was the cause of the red-coloured urine. Abdominal radiographs suggested a splenic mass and a coeliotomy was performed. During the induction and throughout the anaesthetic period the dog was hypertensive and a large haematoma originating from the right retroperitoneal space was identified at surgery. The cause of the haemorrhage was uncertain but a ruptured phaeochromocytoma was thought possible on the basis of the persistent hypertension and the location of the haemorrhage.

Abstract
Parturient haemoglobinuria is a disease of economic importance in buffalo rearing countries in general and in India, Pakistan and Egypt in particular. This study reviews the information on aetiology, epidemiology, clinical aspects and treatment of parturient haemoglobinuria in buffaloes. The body of literature reviewed suggests that phosphorus deficiency in the diet of affected animals plays a major role in causing this disease, although the precise mechanism involved is complex. The possible factors involved and their interplay, plus the clinical picture of affected animals and the results of different preventive and therapeutic regimes are discussed. The study also identifies areas for further research.

Abstract
OBJECTIVE The Edwards Duromedics valve (Baxter Healthcare Corp., Edwards Division, Santa Ana, Calif.) was designed with a self-irrigating hinge mechanism to reduce thromboembolic complications. After good initial clinical results, distribution was suspended in 1988 after reports of valve fracture after 20,000 valves had been implanted. The manufacturer conducted extensive studies to improve the Edwards Duromedics and reintroduced a modified version, which is available as Edwards Tekna. The purpose of the study was the evaluation of long-term results of the original Edwards Duromedics that might be important for the current version, the Edwards Tekna valve. METHODS A prospective clinical 10-year follow-up was performed of 508 patients who underwent valve replacement with the Edwards Duromedics valve in the aortic (n = 268), mitral (n = 183), and aortic and mitral (n = 56) position. RESULTS The perioperative mortality rate was 6.9%; follow-up was 98% complete, comprising 3648 patient-years for a mean follow-up of 86 months (range: 33 to 144 months). The actuarial freedom from complications at the 10-year follow-up and the incidence rate (percent per patient-year) were as follows: late mortality rate, 69.2% +/- 2.4% (3.5% per patient-year); thromboembolism, 90.7% +/- 1.6% (0.96% per patient-year); anticoagulation-related hemorrhage, 87.7% +/- 1.7% (1.34% per patient-year); prosthetic valve endocarditis, 96.7% +/- 0.09% (0.38% per patient-year); valve-related mortality rate, 89.3% +/- 1.6% (1.21% per patient-year); valve failure, 86.2% +/- 1.85% (1.54% per patient-year); and valve-related morbidity and mortality rate, 71.1% +/- 2.3% (3.2% per patient-year). Three leaflet escapes were observed (one lethal, two successful reoperations; 99.1% +/- 0.05% freedom, 0.08% per patient-year). All patients functionally improved (86% in New York Heart Association classes I and II), and incidence of anemia was insignificant. CONCLUSIONS These results confirm that the Edwards Duromedics valve shows excellent performance concerning thromboembolism, hemolysis, and functional improvement and will serve as a reference for the last version, the Edwards Tekna valve, where comparable long-term data are currently not available.

Abstract
A 4-month-old, 6.8-kg, castrated male pygmy goat was examined for recurrent episodic fever and red urine of 7 days' duration. A second, 3-month-old, 7-kg, intact female pygmy goat was presented for similar clinical signs. The red discoloration of the urine in each case was determined to be due to hemolysis with subsequent hemoglobinuria. In both cases, hemolysis and hemoglobinuria were closely associated with the goats consuming large volumes of water from a human infant's nipple bottle. A diagnosis of water intoxication-induced hemolysis and hemoglobinuria was made. Episodes of hemoglobinuria in the first case were consistently associated with dilute (specific gravity < 1.010) urine. Water intoxication has been associated with bottle-feeding in human infants and is also widely reported in human psychiatric patients. The small erythrocytes in goats appear to be the most sensitive of the domestic species to hypotonicity-induced hemolysis.
