In order for women to benefit from adequate community-based care during pregnancy, delivery, and the postpartum, health authorities must provide adequate local services with a sufficient number of trained agents to supervise all deliveries, and the communities themselves must strive to prevent maternal deaths. The community should monitor the health of women, assure access to family planning and prenatal care for all women, and make its members aware of warning signs during pregnancy and delivery. Communities need the assistance of a maternity center or hospital for high-risk pregnancies and difficult deliveries if morbidity and mortality are to be avoided. Each delivery should be attended by a trained person who knows when the delivery is excessively protracted and hospitalization is necessary, what to do in case of hemorrhage or poor presentation of the infant, what rules of hygiene to follow, and how to handle other situations that arise during delivery. Women who are healthy and well-nourished before pregnancy have fewer problems during pregnancy and delivery, and family planning allows high-risk pregnancies to be avoided. Regular prenatal care allows high-risk pregnancies to be identified so that the women can be sent to a hospital for delivery. The expectant mother can be given iron supplements, the 2 injections that will protect mother and infant against tetanus, and antimalarial drugs if necessary. Hypertensive women can be identified, and women can be given advice on child care and family planning. Warning signs before pregnancy include pregnancy within the past 2 years, being under 18 or over 35 years old, family size of 4 or more children, birth of a previous infant weighing under 2500 gm at birth, history of difficult delivery or cesarean, previous premature delivery or stillbirth, maternal weight under 38 kg or height under 145 cm, or chronic illness. Warning signs during pregnancy include failure to gain weight, pallor in the interior of the eyelids, and swelling of the legs, arms, or face. 6 signs requiring immediate attention are vaginal bleeding during pregnancy, intense headaches which may signal high blood pressure, significant vomiting, fever, convulsions, and labor of more than 24 hours. The community should try to ensure that each pregnant woman has a delivery kit in her home ready for use so that the delivery can be safely attended at home if necessary. Women and families should know where to seek further assistance if complications or warning signs occur. Communities can organize 2-way communications by telephone or radio with the referral hospital and can ensure that transportation is always available. Communities can also organize their own forms of insurance so that women can pay for emergency medical care.

The differential diagnosis of acute loss of vision in children includes acute loss of vision due to retinal or optic nerve disease, and cortical blindness. The retinal disorders which may be mis diagnosed as optic neuritis include Leber neuroretinitis, Leber hereditary optic neuropathy, and Stargardt macular dystrophy. Retinal changes which evolve in neuroretinitis, and the pseudopapilledema in Leber heredity optic neuropathy are helpful in differentiating these disorders from optic neuritis. Stargardt macular dystrophy, a disorder associated with a variety of mutations, may be mis diagnosed as psychogenic visual loss due to the early normal appearance of the retina, and the loss of vision over a period of weeks. The differentiation of optic neuritis from anterior ischemic optic neuropathy (AION), depends upon the initial appearance of the optic disc (in AION either hyperemia due to reperfusion, or swelling and pallor if total infarction has occurred). The authors have described children with abrupt loss of vision during renal dialysis, whose risk factors for AION included systemic hypotension and intra ocular hypertension. Children with vigorous treatment of accelerated hypertension, and children with migraine and pro thrombotic disorders have also incurred AION. Thus, AION should be suspected when acute loss of vision occurs in association with certain ocular and systemic risk factors. In children capable of cooperating for visual field examination, the typical change in AION is an altitudinal defect, while optic neuritis it is a central scotoma. The association of optic neuritis with multiple sclerosis, DeVic disease, and with acute demyelinating1 encephalomyelitis require special consideration in regard to treatment and prognosis. Acute loss of vision due to cerebral cortical insults involves a large differential diagnosis which includes vascular, metabolic and infective disease; as well as disorders causing transitory blindness such as seizures and migraine

Episodic spontaneous hypothermia is an infrequent disorder, with unknown pathogenic mechanisms. A systemic cause or underlying brain lesion has not been found for the disease. We report four new patients, 3-9 years old, with episodic hypothermia lower than 35 degrees C, marked facial pallor, and absent shivering. The episodes could last a few hours or four days, and recurred once a week or every 2-3 months. Two patients also demonstrated bradycardia, mild hypertension, and somnolence during the events; in one of them, profuse sweating was also a feature, and all four presented with either headache, a periodic childhood syndrome, or both (recurrent abdominal pain, cyclic vomiting, or vertigo). Three patients reported a family history of migraine. Neurologic examination, endocrine function, and imaging studies were normal. Migraine prophylactic therapy was of moderate efficacy. Spontaneous resolution was observed in one patient. The clinical characteristics of the syndrome allow for its inclusion as a childhood periodic syndrome related to migraine.

Tranylcypromine, a useful antidepressant agent, has been linked with a clinical syndrome of undetermined incidence characterized by exceedingly severe and prolonged headache. Associated phenomena may include paroxysmal hypertension, pallor, chest pain and collapse. This violent reaction does not seem to be related to age, sex, duration of treatment, or pre-existing cardiovascular disease; nor is it possible to predict in whom it will occur. The clinical picture may sometimes be quite similar to that produced by subarachnoid hemorrhage or by pheochromocytoma. The mechanism of action is not known, although it is possible that the syndrome may be due to an amphetamine-like effect; i.e., that tranylcypromine influences the adrenergic component of the reticular activating system. The occurrence of severe headache in the course of tranylcypromine therapy is an indication for immediate withdrawal of the drug. Tranylcypromine cephalgia should be considered as part of the differential diagnosis of sudden, violent and prostrating headache.

Pheochromocytomas are rare tumours of catecholamine-producing chromaffin cells leading to hypertension and symptoms of catecholamine excess. They can be benign or malignant, sporadic or familial tumours. Genetic syndromes associated with pheochromocytoma are MEN II, VHL disease and neurofibromatosis type 1. Usually, pheochromocytomas occur in the adrenal medulla. Clinical manifestations include hypertension (which can be intermittent, stable or in the form of hypertensive peaks) and symptoms related to catecholamine excess such as headache, palpitations and tachycardia, pallor, anxiety and nervousness, nausea, vomiting, weight loss. This clinical syndrome can be mimicked by various hyperkinetic and hyperadrenergic states. When pheochromocytoma is suspected, the first diagnostic step is represented by the measurement of catecholamines and their metabolites (metanephrines) in urine and plasma. Chro-mogranin A measurement can be useful. The clonidine suppression test may be helpful in ruling out other conditions that may elevate catecholamines and metanephrines. Localiza-tion and staging of pheochromocytoma is based on MRI, which is more sensitive than CT scan, and (131)I-MIBG scintiscan. The best therapeutic option for pheochromocytoma is surgery with a laparoscopic approach. An appropriate pre-, intra- and postoperative medical management of the patient is mandatory. In the absence of optimal medical treatment, intraoperative mortality reaches 50%.

OBJECTIVE: To describe an unusual case with clinical features of the antiphospholipid syndrome. DESCRIPTION: White child, two years and six months old, with renal failure, renal arterial thrombosis, and diagnosis of antiphospholipid syndrome was hospitalized with a history of abdominal pain, pallor, lethargy, and anuria for 36 hours. On physical examination, the patient showed malnutrition, high blood pressure, moderate edema, and hypochondrial pain. Laboratory findings included: urea=112mg/dl, serum creatinine= 4.5 mg/dl, blood pH= 7.47, blood bicarbonate= 12.8 mmol/L, K=7.2 mEq/L. Peritoneal dialysis was started and maintained for 11 days. After 7 weeks, the patient still needed anti-hypertensive drugs and the renal function was still abnormal. Renal biopsy was performed and revealed renal infarction. The result of Doppler ultrasonography revealed absent renal blood flow on the right side. Renal arteriography showed total occlusion of the right renal artery. Results for collagen diseases were negative. A right nephrectomy was performed and the blood pressure was controlled. The child was hospitalized again at 5 years and 8 months old with episodes of absence seizures and abdominal and precordial pain. Anticardiolipin antibody test was positive. The child is now 7 years old, asymptomatic, with negative anticardiolipin antibody, and has been under regular follow-up. COMMENTS: Children with arterial thrombosis should be investigated for a possible association with the antiphospholipid antibody syndrome even in the absence of collagen disease.

The splenic rupture is a rare complication of pregnancy and of the postpartum period. On the contrary, hepatic hemorrhage is a relatively common complication of pregnancy and it is usually associated with preeclampsia. In this work we report the case of a 37 year-old patient with a noncontrolled 35 week-pregnancy of simple, with severe preeclampsia. She presented abdominal pain, headache, hypertension and accented cutaneous-mucous paleness at the moment of admission to the hospital. During physical evaluation at admittance, the patient suddenly suffered a severe circulatory collapse and it was decided a surgical intervention. A segmental caesarean section was practiced, and during the abdominal exploration it was observed hemoperitoneous, a splenic rupture degree III and a hematoma in the anterolateral liver's wall. Total splenectomy and evacuation of the hepatic hematoma was performed. The splenic rupture and the hepatic subcapsular hematoma should be considered as a part of the differential diagnoses when a hemodynamic collapse occurs during labor in patients with severe preeclampsia. This work constitutes the first report in the Venezuelan literature of the association of splenic rupture, hepatic subcapsular hematoma and severe preeclampsia. An appropriate prenatal control, the knowledge of this association and an immediate therapeutic intervention are essential to assure the maternal-fetal survival.

Snakebite is not an uncommon cause of acute renal failure (ARF) in developing countries. We report a12-year-old boy who presented with oliguric ARF following snakebite. He had pallor, icterus, generalized edema, hypertension, and was oliguric. Investigations revealed severe azotemia, microangiopathic hemolytic anemia, thrombocytopenia, prolonged coagulation parameters, and raised fibrin degradation products, suggesting disseminated intravascular coagulation as the cause of ARF. The patient improved with antisnake venom, dialysis, and other supportive treatment.

Malignant hypertension may be the first manifestation of systemic hypertension. We report a clinical case of a Caucasian 41-year-old man with no previous history of blood hypertension seen at casualty because of blurred vision. Fundus examination disclosed optic disk swelling, retinal hemorrhages and infarcts. The blood pressure was 220/130 mmHg. After the appropriate management of hypertension, optic disk and retinal edema resolved, leaving minor changes as mild optic disk pallor and hard exudates.

A 34-year-old obese woman developed blurred vision in both eyes soon after large-volume liposuction of the dorsum and gluteus region bilaterally associated with abdominal dermolipectomy. An ophthalmic examination revealed severe bilateral visual loss and pallid optic disc edema. The patient gave a history of transient obscurations of vision in the past. Neuroimaging studies were non-revealing, but a lumbar puncture disclosed a markedly elevated intracranial pressure. The patient was diagnosed as having had bilateral ischemic optic neuropathy superimposed on pre-existing idiopathic intracranial hypertension (IIH). Acetazolamide treatment was used. Some visual improvement occurred, and optic disc edema evolved into severe optic disc pallor. This case shows that visual loss from optic disc infarction may be a devastating complication of high-volume liposuction in patients with underlying IIH. Because liposuction is frequently performed on obese patients, physicians should screen for signs and symptoms of IIH before undertaking this procedure.
