Anaemia, iron status and vitamin A deficiency among adolescent refugees in Kenya and Nepal.

OBJECTIVE: To investigate the prevalence of anaemia (haemoglobin<11.0 to 13.0 g dl(-1) depending on age and sex group), iron deficiency (transferrin receptor concentration>8.3 microg ml(-1)) and vitamin A deficiency (serum retinol <0.7 micromol l(-1)) in adolescent refugees. DESIGN: Cross-sectional surveys. SETTING: Kakuma refugee camp in Kenya and seven refugee camps in Nepal. SUBJECTS: Adolescent refugee residents in these camps. RESULTS: Anaemia was present in 46% (95% confidence interval (CI): 42-51) of adolescents in Kenya and in 24% (95% CI: 20-28) of adolescents in Nepal. The sensitivity of palmar pallor in detecting anaemia was 21%. In addition, 43% (95% CI: 36-50) and 53% (95% CI: 46-61) of adolescents in Kenya and Nepal, respectively, had iron deficiency. In both surveys, anaemia occurred more commonly among adolescents with iron deficiency. Vitamin A deficiency was found in 15% (95% CI: 10-20) of adolescents in Kenya and 30% (95% CI: 24-37) of adolescents in Nepal. Night blindness was not more common in adolescents with vitamin A deficiency than in those without vitamin A deficiency. In Kenya, one of the seven adolescents with Bitot's spots had vitamin A deficiency. CONCLUSIONS: Anaemia, iron deficiency and vitamin A deficiency are common among adolescents in refugee populations. Such adolescents need to increase intakes of these nutrients; however, the lack of routine access makes programmes targeting adolescents difficult. Adolescent refugees should be considered for assessment along with other at-risk groups in displaced populations.

Congenital kala-azar.

An 11-month-old male infant was admitted to hospital with fever, pallor and hepatosplenomegaly, and was diagnosed as having kala-azar. The mother also suffered from kala-azar while carrying this baby. As the baby and the mother did not leave Delhi either during or after delivery, and the vector found in Delhi is not competent to transmit leishmaniasis, the infant could not have been infected by the bite of a sandfly. It therefore seems most likely that he was infected in utero--a rare route.

Familial hemophagocytic lymphohistiocytosis (FHLH).

Clinical course and histopathologic features of a typical case of familial hemophagocytic lymphohistiocytosis (FHLH) are presented. FHLH, initially known as familial hemophagocytic reticulosis (FHR), is rare and without proper treatment is invariably rapidly fatal, usually accompanied by fever, anorexia, vomiting, irritability and pallor. Sporadic examples with prolonged survival have been reported. Other significant findings include hepatosplenomegaly, progressive anemia, leukopenia, thrombocytopenia, hyperlipidemia and hypofibrinogenemia. Varying degrees of hemophagocytosis by widely disseminated histiocytes in different organs and structures is one hallmark of the disease. Hemophagocytosis may also occur in viral and bacterial infections and in certain malignant processes. Very high parental consanguinity in FHLH was mentioned in two relatively recent reports. A probable immunologic defect has been the focus of recent investigations. The genetic defect is believed to be transmitted as an autosomal recessive trait.

Management of arterial emboli. Gleanings from 20 years of experience.

Arterial embolism is usually caused by cardiac disease, and atherosclerotic coronary vascular disease is the primary precursor. Other cardiac states, as well as several uncommon causes, are part of the etiologic spectrum. The earliest signs are pain, paresthesias, pallor, and pulselessness. Severe ischemia is indicated by paralysis, a late feature. Arterial embolism and acute thrombosis can be difficult to distinguish, and deep venous thrombosis may also be suspected in the differential diagnosis. To restore arterial flow, anticoagulation treatment with heparin (Lipo-Hepin, Liquaemin) is given and surgical embolectomy is performed. Heparin infusion is continued until the patient is ambulatory, and then warfarin sodium (Coumadin, Panwarfin) is given over the long term. Fibrinolysis has also been used to treat acute arterial occlusion. Complications of embolism must be carefully guarded against, and additional procedures are sometimes necessary.

Macroamylasaemia, IgA hypergammaglobulinaemia and autoimmunity in a patient with Down syndrome and coeliac disease.

The association between macroamylasaemia and coeliac disease in Down syndrome with multiple autoimmune abnormalities has never been reported. A 40-year-old woman with a 15-year history of immunoglobulin A and immunoglobulin M hypergammaglobulinaemia, chronic diarrhoea, persistent mild aspartate aminotransferase (AST) elevation and anaemic syndrome was admitted to hospital because in the previous 3 months she had developed amenorrhoea, dizziness, alopecia, constipation, pallor and asthenia. Biochemical and immunological analyses showed macroamylasaemia. The patient presented clinical and intestinal histopathological features of coeliac disease. Immunological abnormalities included the presence of antigliadin, antiendomysium, antitransglutaminase, antinuclear, antismooth muscle and anti-SSA/Ro antibodies. Macroamylase resulted in a complex of amylase and immunoglobulin A. Later clinical follow-up of a gluten-free diet showed a transitory decrease in seric immunoglobulin A and macroamylase with persistent autoantibodies and AST elevation. An intestinal mucosal immune disorder could lead to coeliac disease and macroamylasaemia in a patient with Down syndrome presenting other immune alterations.

Phosphatic fertiliser poisoning of sheep: experimental studies.

The toxicity of serpentine phosphate and superphosphate for non-pregnant dry ewes, pregnant ewes and lactating ewes was investigated by oral dosing. An attempt was made to reproduce a natural episode of poisoning by exposing pregnant and lactating ewes to topdressed pasture. A total dose in the range of 1200 to 1800 g of serpentine phosphate was required to kill two ewes and it was concluded that natural episodes of poisoning with this material are unlikely. The toxic process was similar to that caused by superphosphate. The LD50 of superphosphate was estimated to be in the range of 5 to 6 g/kg and a dose in the range of 200 to 300 g was sufficient to kill most sheep. The apparently greater susceptibility of pregnant and lactating sheep to poisoning suggested by the study of natural outbreaks was not demonstrated in these experiments, but the numbers of experimental animals may have been too small to detect differing susceptibility. The clinical disease resembled that seen in natural episodes; anorexia, diarrhoea, progressive depression and death in a period of 5 to 8 days after the start of dosing. Sublethal doses produced a transient diarrhoea and, in two sheep, a severe wool-break. The principal biochemical changes were hyperphosphataemia and evidence of renal failure (oliguria, uraemia, azotaemia). Gross lesions were not consistently present but included abomasal ulceration and renal cortical swelling and pallor. The histopathological evidence of renal tubular obstruction by flocculant eosinophilic casts was characteristic.

Ruptured uterus in Kaduna, Nigeria: a six-year review.

A six year review in a Nigerian University Teaching Hospital revealed that the incidence of ruptured uterus is 1 per 137 deliveries. The mean age of patients was 30.5 years. Ruptured uterus occurred in younger women with a scarred uterus compared with the unscarred group. The incidence of ruptured uterus was highest in women who were para 5 and above. Cephalopelvic disproportion was the most important obstetric factor associated with rupture (63.4%). Abdominal tenderness (46.3%), vaginal bleeding (31.7%) and pallor (31.7%) were the commonest clinical features at presentation. Shock (22%) was commonest in the unscarred group. Repair with tubal sterilisation was the commonest method of treatment. Diarrhoea was the commonest postoperative complication (39%). Maternal and perinatal mortality rates were 22% and 88% respectively. Improving the emergency capability of the hospital and more efforts at educating our women and reducing poverty will go a long way towards reducing the incidence and adverse clinical outcome of ruptured uterus.

Persistent splenomegaly in an adult female with homozygous sickle cell anemia.

Sickle cell anemia (SCA) is associated with repeated episodes of erythrostasis in the spleen, which lead to thrombosis and infarction of the spleen resulting in "autosplenectomy" which is usually complete by 8 years of age. We present a case of a 22-year-old female who presented with complaints of fever, bone pain and joint swelling. On examination she had pallor, icterus and moderate splenomegaly. Her hemoglobin was 7.5 g/dl. Peripheral smear showed many sickled red cells. Slide test for sickling was positive with 2% sodium metabisulphite. Hemoglobin electrophoresis revealed a single band in the hemoglobin S, D, and G region. No band was seen in the HbA & HbA(2) region. HbF level was 0%. USG showed an enlarged spleen with few defined hypoechoeic lesion. We present this case because of rarity of association of homozygous SCA with splenomegaly in this age group, the confusion that echogenic lesions in spleen can create and to emphasize the risk of sequestration crises, which remains in such cases.

An epizootic of cutaneous zygomycosis in cultured dwarf African clawed frogs (Hymenochirus curtipes) due to Basidiobolus ranarum.

Morbidity and mortality approaching 100% occurred in dwarf African clawed frogs (Hymenochirus curtipes) from a culture facility in central California. Moribund frogs exhibited preference for a terrestrial environment rather than their normal aquatic environment. Affected animals had a slight pallor of the integument but were otherwise grossly unremarkable. Microscopic examination revealed a fungal infection of the integument primarily characterized by the presence of surface and intra-epidermal conidia. Skin cultures of the infected animals yielded an organism identified as Basidiobolus ranarum, based on the formation of conidia in culture with internal cleavage to form sporangiospores. The organism was transmitted to healthy frogs by co-habitation with infected frogs but not by short-term immersion exposure of healthy frogs to homogenized broth cultures of the fungus. Benzalkonium chloride at 2.0 mg l-1 was efficacious in controlling the infection. Although Basidiobolus species are normally found in the intestinal tract of amphibians, the severity of this epizootic indicates that B. ranarum may be an important pathogen of amphibians reared in culture facilities.

Problems in the clinical diagnosis of typhoid fever in children in the tropics.

Between January 1976 and December 1978, the Microbiology Department of University College Hospital (UCH) Ibadan, isolated Salmonella typhi from the blood cultures of 93 children aged 0-14 years, who were admitted to the paediatric wards. Clinical case notes were retrieved and reviewed in 64 (68.8%) of them. Fifteen (23%) of the 64 children were less than one year of age while 22 (34%) were under the age of five years. The commonest presenting symptoms were fever, anorexia, diarrhoea and vomiting. A febrile convulsion was the presenting symptom in 13 (20%) of the patients, all of whom were under the age of five years. Hepatomegaly was almost twice as frequently observed as splenomegaly. Intestinal perforation was present in five of the patients. There was a high proportion of SS children who presented with fever, pallor, jaundice, generalized aches and pains and other clinical features of sickle cell disease and it is possible that such children are specially susceptible to typhoid fever. A clinical diagnosis of typhoid fever on admission was made in only 14 of the 64 children. Reasons are given for the low index of suspicion and it is suggested that any child with unremitting fever after adequate anti-malarial chemotherapy should be treated for enteric fever.

Clinical profile of malaria in children--a prospective study from Aligarh (N. India).

In a prospective, hospital-based study in North India, malaria accounted for 1.5% of paediatric outpatient attendances during 1 year. A marked increase in the prevalence of malaria was noted during the post-monsoon months. Plasmodium falciparum was the causative species in 44.4% of cases, contrary to previous reports of low prevalence of this parasite in the area. Pyrexia with or without chills or rigor, vomiting, pallor and hepatosplenomegaly were the common presenting clinical features. Splenic and hepatic enlargement were seen more frequently with P. vivax than P. falciparum infections (P less than 0.001 and P less than 0.01, respectively). Convulsions were present in 20% of cases.

Acute illness in Nigerian children with sickle cell anaemia.

The pattern of illness in 60 consecutive children with homozygous sickle cell disease who attended the Paediatric Emergency Room of a busy Lagos hospital with acute illness was studied prospectively. Their ages ranged from 3 months to 13 years with a peak in the 2nd year. There were twice as many boys as girls. The commonest symptoms were fever, limb or abdominal pain and cough, and the commonest signs were pallor and hepatomegaly. Painful crises occurred in 27, anaemic crises in 11, and a combination of these in 12 children. Infection was detected in 76% of subjects in crises. Infection was found in 82% of all the children and was mainly bacterial. The commonest infections were pneumonia (35%), bacteraemia (32%), tonsillitis/pharyngitis (17%) and osteomyelitis (8%). The predominant bacteria isolated were Klebsiella spp (38%), E. coli (23%), Staph. aureus (23%), Staph. albus (23%) and Pseudomonas spp (23%). Some children had multiple isolates. Bacterial infection was a major cause of morbidity in very young children and merits appropriate control and preventive measures in this age group. The spectrum of bacteria isolated makes it unlikely that the specific anti-pneumococcal measures widely advocated in Europe and America for young children with SCA would be appropriate in Nigeria.

Congenital hypoplastic anaemia in Arab children (Diamond-Blackfan syndrome).

Three Arab children with congenital hypoplastic anaemia are reported. The three children presented with pallor in the first 3 months of life. All were given corticosteroids at different times. The first child is on high doses of prednisone and also needs blood transfusion every 6 weeks. The second child is on 5 mg prednisone every other day and is in remission. The third has been in complete remission for the last 5 years and is on no treatment. None of these children has associated congenital or chromosomal abnormalities.

Visceral leishmaniasis in Libya--review of 21 cases.

Visceral leishmaniasis is an important public health problem in Libya, but its exact prevalence is not known. Prompted by the paucity of information in the literature relevant to Libyan children, we reviewed the records of 21 children treated at El-Fatah Children's Hospital, Benghazi between March 1982 and May 1990. Visceral leishmaniasis was diagnosed on the basis of the history, physical findings and confirmatory laboratory tests including examination of bone marrow. The duration of illness before seeking medical advice ranged from 3 months to 1.5 years. The commonest presenting features were fever, abdominal distension, anorexia with weight loss, hepatosplenomegaly and pallor. The consistent laboratory findings were anaemia with reticulocytosis and normal serum iron, neutropenia, thrombocytopenia, high ESR and hyperglobulinaemia. The bone marrow was positive for L. donovani in 86% of cases and the indirect haemagglutination test was positive in all patients. Bronchopneumonia was the most common complication and responded rapidly to antibiotics. All patients were treated with sodium stibogluconate 10 mg/kg/day. There were no major side-effects or complications of drug therapy. The relative paucity of cases and their late presentation may reflect a lack of awareness of the occurrence of visceral leishmaniasis by doctors in the community.

Diethylene glycol poisoning in Nigerian children.

Between June and September 1990, 47 children died at Jos University Teaching Hospital, Nigeria from ingestion of paracetamol syrup adulterated with diethylene glycol. Most of the children presented with anuria, fever, vomiting, diarrhoea and convulsions. Signs on admission were tachycardia, acidotic breathing, pallor, oedema and hepatomegaly. Laboratory findings included hyperkalaemia, acidosis, elevated creatinine level and hypoglycaemia. Management consisted of correction of dehydration and acidosis plus administration of antibiotics when indicated. None of the children had dialysis. All died within 2 weeks of admission. Proper government supervision of pharmaceutical companies and their agencies is urgently needed in order to prevent any future occurrence of such tragic deaths.

Acute intravascular haemolysis in glucose-6-phosphate dehydrogenase deficiency.

Thirty-five children with G6PD deficiency, who presented with acute intravascular haemolysis, were evaluated to define its aetiology, clinical features and ultimate outcome. All were boys with ages ranging from 6 months to 12 years. Pallor of abrupt onset and passage of cola-coloured urine were universal presenting symptoms. Incriminating factors responsible for haemolysis include hepatitis (7), malaria (4), bacterial sepsis (3) and drug intake (24), with more than one predisposing condition existing in some children. Marked elevations in serum bilirubin, coinciding with intravascular haemolysis, was a feature in all the seven children with hepatitis. Azotaemia was noted in 20 patients, of whom 14 did not have oliguria. All four children with malaria presented with protracted renal failure. Therapy focused on maintaining a high urine output in those without oliguria. A total of 15 peritoneal dialyses and five haemodialyses were required in six patients with acute renal failure, all of whom were oliguric. Supportive therapy consisted of blood transfusions and treatment of the predisposing diseases. Thirty-two children recovered completely while three died, the cause of death being severe anaemia and congestive cardiac failure, malaria with oliguric renal failure and hepatic encephalopathy, respectively.

Aetiology of chronic diarrhoea in children: experience at King Khalid University Hospital, Riyadh, Saudi Arabia.

Forty-eight cases of chronic diarrhoea in children seen at King Khalid University Hospital over a 5-year period were analysed. The mean age at presentation was 1.8 years (range 0.08-10 years); 34 were boys and 14 girls. Forty-four patients were Saudi and four were non-Saudi Arabs. Most children presented with failure to thrive and pallor. The aetiological factors identified were: the post-gastro-enteritis syndrome with or without lactose intolerance in 16 (33%); coeliac disease in ten (21%); congenital chloride diarrhoea in five (10%); glucose-galactose malabsorption and acrodermatitis enteropathica, each in three (6%); ulcerative colitis, intestinal lymphangiectasia, cow's milk protein intolerance and ataxia telangiectasia, each in two (4%); and giardiasis, immune deficiency and cystic fibrosis, each in one (2%).

Haemorrhagic disease in newborn and older infants: a study in hospitalized children in Kelantan, Malaysia.

This is a retrospective study of the epidemiology, clinical features, laboratory findings, treatment and outcome of haemorrhagic disease in 42 Kelantanese infants who were admitted to Hospital Universiti Sains Malaysia during a 2-year period (1987-1988). Classical haemorrhagic disease of the newborn was the commonest presentation (48%), followed by early onset (29%) and late onset (24%) disease. Home deliveries accounted for 81% of the affected infants. Most of these babies were not given vitamin K at birth in contrast to those delivered in hospitals. All except one infant were breastfed. The six commonest presenting clinical features were pallor, jaundice, umbilical cord bleeding, tense fontanelle, convulsions and hepatomegaly. All the infants had prolonged prothrombin and partial thromboplastin times which were corrected by administration of vitamin K. Subdural haemorrhage was the commonest form of intracranial haemorrhage, followed by subarachnoid haemorrhage. The overall case fatality rate was 14%. The results of this study once again emphasize the value of vitamin K prophylaxis in the newborn.
