The relationships of certain etiological factors (sex, age, family history of febrile convulsions or epilepsy, term, birth weight, prenatal or perinatal anomalies, temperature, cause of fever) to the duration and localization of the first febrile convulsion (FC) were studied in 402 patients. In patients with prolonged seizures (over 30 min), the mean age was younger, the proportion of girls, common infectious diseases of childhood, and immunization was higher and that of respiratory infections lower than in patients with brief convulsions. In patients with unilateral seizures, the proportion of positive family histories and respiratory infections was lower and that of common infectious diseases of childhood and of immunization was higher than in patients with bilateral convulsions. The association of each of these etiological factors with the duration or lateralization of the first FC was independent of the others.

Two hundred thirty-one cases of neurocysticercosis are reviewed. Diagnosis was established by cerebral computed tomography during a seven-year period (1983-1989). One hundred and fourty-four (62%) presented with symptom-related disease (symptomatic neurocysticercosis and in 87 the diagnosis was incidental (asymptomatic neurocysticercosis). In symptomatic neurocysticercosis the parasitosis was considered inactive in 115 cases and active in 29. Seizures occurred in 135 patients (96% of the symptomatic neurocysticercosis). In the active form we also found: meningitis (n = 15), intracranial hypertension (n = 12), hydrocephalus (n = 10) and arteritis (n = 2). Treatment included praziquantel (n = 21), albendazole (n = 4), dexamethasone (n = 18) and surgery (n = 10).

Convulsive conditions account for 69.8% out of the total number of patients admitted to the department of intensive care of the children's neurological hospital. In 25.3% (348 children) they first developed in the presence of somatic pathology of the infectious inflammatory genesis in children with perinatal brain injury. Acute somatic pathology (acute respiratory diseases, pneumonia, intestinal infections) dominated (n = 318). In all the children, convulsive seizures occurred in hyperthermia largely in early childhood. Apparently, in the majority of cases, perinatal injury alone was insufficient to precipitate seizures. However, the combined perinatal brain injury and an infectious disease form favourable conditions for the appearance of convulsive conditions in children. Therefore, to prevent them, of importance is the prophylaxis of both perinatal pathology and infectious diseases. The patients with convulsive conditions should be given combined treatment including anticonvulsants, antiinflammatory, antibacterial, detoxication and other drugs.

Aircrew are subject to flight and duty restrictions for various health-related problems. The major classifications of aeromedical limitations in the US Coast Guard are: Fit For Limited Duty (FFLD), fit for Duty Not Involving Flying (DNIF), and Sick In Quarters (SIQ). I studied the etiology and distribution of these restrictions among aircrew at a busy Coast Guard Air Station. Data were collected over a 6-month period from personnel Health Records and various medical reporting systems. A total of 391 health care episodes among 179 (56.6%) flight crew resulted in 1,961 days of flight/duty restriction. There were 1,349 (68.8%) days of DNIF, 439 (22.4%) days of FFLD, and 173 (8.8%) days of SIQ. The annual crude rate of restrictions per flight crew is 12.4 d. The most common causes for flight or duty restriction were infectious diseases of the respiratory and gastrointestinal tract and musculoskeletal problems. In conclusion, aeromedical flight/duty restrictions are substantial and have impact on flight crew availability.

A prospective study of the neurological manifestations in all patients with systemic lupus erythematous (SLE) was conducted between February 1985 to January 1989. Excluding herpes zoster infection of peripheral or cranial nerves, post-herpetic neuralgia and migraine, 36 neurological episodes occurred in 33 patients. The presenting symptoms were mental confusion (10), psychosis (five), seizures (six), focal neurological deficit (three), coma (two), headache (five), blurring of vision (three), neuropathy (one) and myelopathy (one). Of these manifestations, only eight episodes were due to primary involvement by SLE: psychosis (two), seizure (two), multiple cerebral infarcts (one), papillitis (one), neuropathy (one) and myelopathy (one). Infection was the most common secondary cause of neurological episodes: all 10 episodes of mental confusion (fungal seven, pyogenic two, tuberculous one, nocardial one); two of six seizures (tuberculous one, pyogenic one); all five headaches (tuberculous meningitis three, cryptococcal meningitis two). The other secondary causes included steroid psychosis (two), hypertensive encephalopathy with seizure (one) and hypertensive retinopathy (one). Three of five cases of focal neurological deficit were due to macrovascular disease rather than to vasculitic infarction. We concluded that cerebral psychosis was a relatively rare presentation in our patients with SLE. In patients who presented with a neurological problem, especially mental confusion, efforts should be made to ascertain the underlying cause, especially if this may be an infection.

In past decades, most individuals with Down syndrome were usually not afforded adequate medical care. Many children with Down syndrome were institutionalized and they were often deprived of all but the most elementary medical services. Fortunately, there have been major improvements in the health care provision during the past 20 years. Professionals who are providing services to persons with Down syndrome need to be aware of those clinical conditions that are more often observed in this population. Certain congenital anomalies (congenital cataracts, anomalies of the gastrointestinal tract, and congenital heart disease) often require immediate attention, as some of them may be life threatening. During the subsequent childhood years a number of clinical conditions and disorders such as infectious diseases, increased nutritional intake, periodontitis, seizure disorders, sleep apnea, visual impairment, audiologic deficits, thyroid dysfunction, and skeletal problems usually occur at a higher prevalence. During adolescence specific aspects of maturation and certain health issues (skin infections, thyroid disorders, increased weight gain, and others) as well as mental health concerns need to be taken into consideration. Similar concerns may also be observed during adulthood which in addition is often marked by accelerated aging and the threat of Alzheimer disease in some persons with Down syndrome. Special attention needs to be paid to these disorders and conditions during the lifetime of a person with Down syndrome. Appropriate medical care should be provided to and no form of treatment should be withheld from a person with Down syndrome that would be given unhesitatingly to an individual without this chromosome disorder.

From the medical records of 238 intensive care unit (ICU) patients who had infections with gram-negative pathogens commonly associated with serious illness, we developed a predictive score of clinical risk factors for seizures. To evaluate the predictive ability of this score, we applied it to a separate population of 645 seriously ill hospitalized patients with similar gram-negative infections who were in antibiotic clinical trials. The patients at highest risk were classified into one of the following three categories: (a) patients with major central nervous system (CNS) insults (CNS surgery, hemorrhage, infection, or other lesion within 1 month before hospital admission or any history of CNS neoplasia), (b) patients with a predisposing factor (renal impairment or a history of seizures) plus a precipitating factor (anoxic encephalopathy/coma or an acute hypotensive episode), and (c) patients with both renal impairment and a history of seizures. Receiver operating characteristic (ROC) curves were calculated in each of the two populations. The area under the ROC curve (AUC) represents the probability that the score would rank a randomly chosen patient who subsequently had a seizure as having had a greater prior level of seizure risk than a randomly chosen patient who did not experience a seizure. The AUC was 0.87 (SE = 0.05) for the original population used to develop the score and 0.81 (SE = 0.04) for the population used for the validation study. The clinical risk score, based on readily available information, provides a useful means to identify among seriously ill infectious disease service patients, those who are at highest risk for seizures. It also serves as a baseline for evaluating the non-drug-related risk factors for seizures in patients treated with antibiotics.

We conducted a prospective, double-blind, placebo-controlled study in adult patients to determine whether prophylactic penicillin prevents infection in intraoral lacerations secondary to minor trauma or seizures. Uninfected full-thickness, mucosal-only, or through-and-through wounds presenting within 24 hours of injury were considered. Management consisted of cleansing, irrigation, debridement, and closure as indicated: no topical antibiotics were applied. Patients were randomly assigned to receive penicillin VK 500 mg or identically appearing placebo four times daily for five days. Home wound care was standardized and patients were followed for a minimum of four or five days. Infection was assessed clinically. Seventy-six patients were enrolled and 62 completed the study. Penicillin (30) and placebo (32) groups were similar in all parameters except wound etiology; assault was more common in the placebo group (P = .02). Two infections occurred in patients receiving penicillin, and six infections were seen among placebo-treated patients (P = .05, beta = 0.17). When patients poorly compliant with therapy were eliminated from analysis, none of the penicillin-treated patients and five of the placebo-treated patients developed infections (P = .027). Our data suggest that patients with intraoral wounds may benefit from prophylactic penicillin if compliant with their therapy. More studies are needed to further delineate the usefulness of prophylactic antibiotics for these wounds.

Recent improvements in the results of orthotopic liver transplantation (OLT) have made this a well-accepted treatment for patients with severe hepatic failure. Current problems encountered following OLT are discussed. Immediate complications comprise surgical bleeding, primary graft non-function, and graft failure due to hepatic artery occlusion. Secondary complications are frequent. Surgical ones include biliary and vascular (hepatic artery thrombosis most often) problems, as well as intra-abdominal abscesses associated with gastrointestinal perforation, biliary leak, graft ischaemia or an infected haematoma. 40% of patients having undergone OLT will be reoperated on, 2/3 of them within 3 months. Non-surgical complications are mostly pulmonary. The risk of pneumonitis is increased by prolonged mechanical ventilation; it is always potentially disastrous in the immunosuppressed, transplanted patient. Hypertension is also often seen in the early postoperative period; it requires prompt treatment. Early renal impairment after OLT is common, and of better prognosis than late onset renal failure, which is generally associated with shock, graft failure, sepsis or use of nephrotoxic agents. Seizures, usually only one, occur in about 10% of patients; recovery is complete. Encephalopathy with intracranial oedema related to fulminant hepatitis has a worse prognosis, but survival figures are quite encouraging. Three type of rejection are described after OLT: 1) severe accelerated rejection (very rare), 2) acute rejection encountered in about 70% of patients over the first 3 months, and 3) late rejection, which can lead to the vanishing bile duct syndrome (VBDS). Diagnosis of rejection is made by liver biopsy. Prophylactic immunosuppression includes cyclosporin, methylprednisolone and azathioprine. Cyclosporin toxicity and drug interactions are reviewed. Treatment of acute rejection episodes comprises an initial bolus of high doses of corticoid drugs; if there is no response, antilymphocyte globulin or monoclonal antibodies may have to be used. Infection is the main cause of death following OLT. Early infections, mostly intra-abdominal and pulmonary, are bacterial or fungal. Vital (especially CMV) and other opportunistic infections occur generally after the second week. Retransplantation, carried out in 10 to 25% of patients, may be urgent in case of primary graft failure, or hepatic artery thrombosis associated with graft failure, or hepatic artery thrombosis associated with graft failure. Other indications are early graft rejection with severe hepatic dysfunction, chronic rejection with severe VBDS, and recurrence of the initial disease.

Imprecise diagnosis of birth asphyxia coupled with uncertainties about causal factors for neurologic abnormalities in the newborn have greatly fueled the current litigation crisis in obstetrics. Our goal was to more precisely define birth asphyxia based on fetal condition as measured by umbilical artery blood pH, Apgar scores, and neurologic condition of newborns. We selected for study 2738 patients with singleton pregnancies with cephalic presentations who were delivered of infants at term to avoid complications such as prematurity, which may affect infant outcome independent of birth condition. The basis for study of these particular patients were defined criteria for high risk and an indicated arterial cord pH value. A total of five infants demonstrated cerebral dysfunction as evidenced by seizures during the neonatal period. Infection was linked to seizures in three of these infants; one infant had neonatal asphyxia and only one infant's clinical course could be attributed solely to birth events (uterine rupture). Stratification of umbilical artery blood pH values, Apgar scores, and combinations of these dependent variables in relation to newborn clinical outcomes revealed that infants must be severely depressed at delivery before birth asphyxia can be reliably diagnosed. Such depression includes Apgar scores less than or equal to 3 at 1 and 5 minutes plus umbilical artery pH values less than 7.00.
