We conducted a retrospective study of the management and outcome for eclampsia patients in the intensive care unit (ICU) of National hospital, Abuja between November 2001 and April 2005 (42 months). The patients' case files and ICU records were used to extract the necessary data. During the study period, there were a total of 4857 deliveries, with 5051 total births (including multiple births) and 4854 live births. Forty eclamptics were admitted to the ICU, giving an ICU admission rate of 8.2/1000 live births. The records of two patients were incomplete. The average age of the patients was 28.4 years (range 17-4 years). Six patients (15.8%) were booked and 32 (84.2%) were not. The average duration of stay in ICU was 5 days. Twenty patients (52.6%) had antepartum eclampsia, 12 (31.6%) had postpartum eclampsia and six (15.8%) presented with intrapartum eclampsia. Twenty-nine (76.3%) gave birth via caesarean section and nine (23.7%) delivered per vagina augmented by oxytocin infusion. Seventeen (45%) received mechanical ventilation; 20 (53%) received oxygen via nasal prongs, nasal catheters or variable performance facemask. One patient (2%) did not receive oxygen therapy. All the patients were admitted postpartum. There were 11 maternal deaths, giving a case fatality rate of 29%. There were five (45.4%) deaths due to haemolysis, elevated liver enzymes and low platelet count syndrome and two (18.2%) due to disseminated intravascular coagulation. The remaining deaths were due to cerebrovascular accident (9.1%), lobar pneumonia (9.1%), acute renal failure (9.1%) and multiple organ failure (9.1%). All patients were admitted postpartum. This fatality rate is higher than that detailed in the reports reviewed in this study. Early referral of eclamptics or at risk patients to a tertiary care institution may help reduce morbidity and mortality. In addition, early referral to a facility providing basic essential obstetric care or comprehensive essential obstetric care is also important. Another important factor is the correct diagnosis of pre-eclampsia during antenatal and postpartum care by screening, noting blood pressure levels, performing urinalysis for protein and asking about warning signs such as headache, blurred vision, epigastric pain, etc.

The range of diseases in which intravenous immunoglobulin (IVIG) is effective has expanded significantly since its initial use in primary antibody deficiency. This biological medicine must comply with three conditions: therapeutic efficacy, clinical tolerance and viral safety. Factors relevant to the viral safety of IVIG include: effective use of donor exclusion criteria, screening of donations in order to exclude potentially infectious donations, testing of plasma pools for evidence of viral infection, validated steps for removal and/or inactivation of potentially present infectious agents, equipment cleaning, traceability of lots, and post-marketing follow-up of patients. Variables potentially affecting the risk and intensity of adverse events associated with administration of IVIG include: patient age, underlying condition, dose, concentration, IgA content, stabilizing agent and rate of infusion. Mild adverse reactions (headache, flushing, low backache, nausea) are often associated with a fast infusion rate, and respond rapidly on slowing the infusion. Very rare serious and potentially fatal side effects include: anaphylactic reactions, aseptic meningitis, acute renal failure, and thrombotic complications. Many of these serious adverse reactions have occurred in patients who had significant risk factors or underlying disease states. Clinicians should pay close attention to patient selection and consider the potential risk/benefit ratio versus alternate therapies.

Idiopathic intracranial hypertension remains a disease of unknown etiology. Epidemiology, associations, features, and prognosis in children have changed over the years. The main clinical complaint of pediatric idiopathic intracranial hypertension is headache with visual disturbance. We report on a patient with childhood idiopathic intracranial hypertension, who presented without headache after hemodialysis for acute renal failure. Idiopathic intracranial hypertension without headache is believed to have a poor prognosis. However, this child demonstrated a favorable outcome with medical therapy. The child was followed with serial optical coherence tomography of retinal nerve fiber layer thickness around the optic nerve head. In the absence of a reliable procedure to evaluate the therapeutic efficacy in the follow-up of patients with idiopathic intracranial hypertension, the importance of optical coherence tomography, a noninvasive, objective, and reproducible procedure, is highlighted as a useful adjunct in the management of idiopathic intracranial hypertension.

Familial renal hypouricemia is a hereditary disease characterized by extraordinary high renal uric acid clearance and is associated with acute renal failure (ARF). An 18-year-old sumo wrestler developed ARF after anaerobic exercise. Several hours after the exercise, he had a pain in the loins with oliguria, headache, and nausea. On admission, his serum uric acid was decreased despite the elevation of serum creatinine (9.5 mg/dL). The level of creatine kinase was normal and there was no myoglobinuria or urolithiasis. Magnetic resonance imaging showed no significant abnormality. Renal function improved completely within 2 weeks of hydration treatment. After remission, hypouricemia became obvious (1.0 mg/dL) from the initial level of uric acid (6.1 mg/dL) and fractional excretion of uric acid was 49%. Polymerase chain reaction of a urate anion exchanger known to regulate blood urate level (SLC22A12 gene: URAT1) demonstrated that homozygous mutations in exon 4 (W258X). Both parents showed heterozygous mutation of the URAT1 gene, but both siblings showed no mutation. Thus, we describe a Japanese sumo wrestler of familial renal hypouricemia complicated with anaerobic exercise-induced ARF, with definite demonstration of genetic abnormality in the responsible gene, URAT1.

Hypertension is the most common cardiovascular condition in the United States. It can lead to end organ damage and increased mortality risk if it is not properly controlled. In most situations where blood pressure has to be brought down quickly, an intravenous agent with a quick onset of action is often used. Clevidipine is the first third-generation IV dihydropyridine calcium channel blocker that has a high degree of vascular selectivity and an ultra-fast onset and offset of blood pressure lowering effect. In various clinical trials, clevidipine has shown to be safe and effective in controlling acute blood pressure elevations in patients with hypertensive emergencies, preoperative hypertension, and postoperative hypertension. The most common adverse events noted are atrial fibrillation, nausea, headache, and acute renal failure. Overall, clevidipine is a useful addition to available intravenous agents in reducing blood pressure during acute situations. The acceptance of this agent to hospital formularies may ultimately depend on its perceived ease of administration, clinically relevant benefits over other available agents, and acquisition costs.

Scleroderma renal crisis (SRC) occurs in 5-10% of SSc patients, who may present with an abrupt onset of hypertension, acute renal failure, headaches, fevers, malaise, hypertensive retinopathy, encephalopathy and pulmonary oedema. Patients at greatest risk of developing SRC are those with diffuse cutaneous or rapidly progressive forms of SSc, and treatment with a recently commenced high dose of corticosteroid. Laboratory tests may demonstrate hypercreatinaemia, microangiopathic haemolytic anaemia (MAHA), thrombocytopaenia and hyperreninaemia. Renal crisis is also linked to a positive ANA speckled pattern, antibodies to RNA polymerase I and II, and an absence of anti-centromere antibodies. Early, aggressive treatment with angiotensin-converting enzyme inhibitors has improved prognosis in SRC, although 40% of the patients may require dialysis, and mortality at 5 yrs is 30-40%. Median time to recovery is 1 yr, and typically occurs within 3 yrs. Prognosis is worse for males, but may not be related to corticosteroid use, presence of MAHA or severity of renal pathology. Modification of endothelin over-activity, which is implicated in the pathogenesis of SRC, may offer a future therapeutic approach.

Acute renal failure is a significant complication of falciparum malaria and is associated with increased morbidity and mortality. It occurs rarely in children and is seen frequently among the adults. Malaria associated renal failure may occur as a sole complication or as a component of multiple complications. Some of the patients may have normal urination (non-oliguric) and usually have better prognosis even without renal replacement therapy. Only a few research studies are available from Indian subcontinent on malarial acute renal failure. The present study is a hospital based study from eastern India. Rourkela is situated in the western part of Orissa which contributes a large number of falciparum malaria cases. The study was conducted at the internal medicine department of Ispat General Hospital. The clinical presentation of malaria patients in 2001 were analysed with special emphasis on malarial acute renal failure. The difference between patients with or without renal failure was compared. Seven hundred eighteen patients admitted to Ispat General Hospital in 2001 above the age of 14 years were analysed. Of these, 84 (11.8%) had serum creatinine >3 mg/dl. Seventy-five patients were referred from different hospitals outside the township. The presenting complaints were fever (95%), oliguria (55%); loose motions (25%), and vomiting (51%). Headache was present in only 20% patients. Similarly, hypotension was encountered in about a third. Associated complications were significantly more common among patients having renal failure viz, Jaundice (77 versus 19%; p < 0.001), Cerebral malaria (59 versus 11%; p < 0.001), and hypoglycaemia (p < 0.05). The mortality in presence of acute renal failure was high (p < 0.001). Though malaria renal failure is a burning issue, still scant data is available in the literature, including India. The present study is an attempt to study the patients admitted to a referral hospital. The reason for high mortality is due to presence of multiple complications. The present study indicates that the presence of acute renal failure and jaundice together adversely influences the mortality. Hence, studies may be carried out to find out the reason of this changing trend as well as the methods to ameliorate/manage the situation.

For many years, non-steroidal anti-inflammatory agents, steroids and immunosuppressive drugs have been the mainstay of treatment for rheumatological disorders. Over the last few years, the emergence of biologic treatments has dramatically changed the management of numerous rheumatological diseases. However, immunoglobulin treatment has been used for decades and its use has still not been superseded in certain rheumatological diseases. In fact, despite the introduction of newer immunomodulatory drugs, there has been an ever-increasing number of clinical indications for which intravenous immunoglobulin (IVIG) has been tried. Immunoglobulins are plasma proteins secreted by plasma cells, forming a major component of the adaptive immune system. IVIG is a blood product prepared from plasma, each batch prepared from a pool of 10,000-20,000 donations. Multiple purification steps during the manufacturing process aim to eliminate all known transmissible pathogens, but cannot completely exclude the risk from unknown pathogens. It should be noted that there has been the transmission of hepatitis C in one batch of immunoglobulin, reported in 1994, resulting in more than 200 patients in the USA and Europe being affected. Nevertheless, IVIG remains relatively safe compared with other immunosuppressive drugs. Headaches and fatigue are common side effects but fortunately the more severe problems such as aseptic meningitis, venous thromboembolism and acute renal failure remain rare. High-dose immunoglobulin when administered i.v. has immunomodulatory properties. The precise mechanism of action of IVIG is complex and not yet fully understood.

From 2000 to 2007, 19 Austrian children (aged 6-18 years) had serologically verified nephropathia epidemica. Common clinical features were abdominal/flank/back pain, fever, nausea, vomiting, headache, and transient visual disturbances. Acute renal failure was present in 18 (95%) patients. All patients recovered completely. Childhood nephropathia epidemica in Austria takes a similar course to those reported for Northern European Puumala virus strains.

Hashimoto's thyroiditis is the commonest form of autoimmune thyroiditis in the world. It occurs most frequently in women (female/male ratio, 6:1) in the age group between 30 and 60 years. Here we report the case of a 38-year-old Caucasian man who presented with a few days' history of upper limb paresthesias, widespread joint and muscle pain, and headaches. Laboratory findings showed increased CPK, myoglobin and plasma creatinine levels with acute renal failure. Low free T3 and T4 values associated with a high TSH value, the presence of antithyroid globulin and peroxidase autoantibodies pointed to a diagnosis of hypothyroidism with Hashimoto's thyroiditis. Treatment with levothyroxine was initiated and within 2 months normalization of renal function, myoglobin, CPK and thyroid hormone levels was observed.
