Analysis of mode of delivery in cases with fetal premature atrial contractions

OBJECTIVE: Premature atrial contractions are common in obstetrical practise but there is little information available on recommended management and mode of delivery. DESIGN: The aim of the study was to describe our clinical experience in the management of fetal arrhythmia including the indications for certain time and way of labour. MATERIALS AND METHODS: 128 fetuses with diagnosed supraventricular arrhythmia described as atrial extrasystole were examined. They were divided into 3 main groups: group I (84 fetuses) with single PAC, group II (37 fetuses) with quantitatively significant arrhythmia or accompanied by another kind of arrhythmia and group III (7 fetuses) associated with extracardiac abnormalities. RESULTS: Among 128 fetuses with supraventricular arrhythmia, 44 cases (31%) required systematic monitoring. Quantitatively significant arrhythmia was recognized in 15 cases, blocked bigeminy (2:1) in 2 fetuses, 10 cases were accompanied by another arrhythmias: 4x SVT, 4x sinus bradycardia, 2x premature ventricular contractions (PVC). There were 3 fetuses diagnosed with heart defects and 7 with extracardiac malformations. Fetal echocardiography revealed additional functional circulatory changes in 7 fetuses with premature atrial contractions. Myocarditis was recognized in 2 fetuses. The mode of delivery was analyzed in 128 cases. In the first group 27 patients (32%) underwent caesarean section, in the second group--23 (62%), in the third group 3 patients (43%), respectively. Cardiac indications for caesarean section equalled 22% of all the indications occurring in fetuses suffering from arrhythmia. CONCLUSIONS: Caesarean section is much more commonly performed among fetuses diagnosed with arrhythmia accompanied by another fetal anomalies comparing to the group of fetuses with isolated arrhythmia. Although there are no particular cardiac indications for such way of delivery, total amount of caesarean sections performed in that group is really great. Above all, it may suggest that the obstetrician is under pressure of stress while making decision concerning caesarean section performance, even when there are no other indications and the condition of fetus is stable enough.     

Nursing at ground zero: experiences during and after September 11 World Trade Center attack

The purpose of this study is to discover shared perceptions, feelings, and common experiences of nurses after the September 11th World Trade Center terrorist attack through interpretive analysis of narrative stories of seventeen nurses. Six themes and one constitutive pattern describe the experiences: (a) Loss of a symbol and regaining new meaning, (b) Disaster without patients, (c) Coordinating with and without organizations, (d) Rediscovering the pride in nursing, (e) Traumatic Stress, and (f) Preparing for the future. The constitutive pattern is that nursing enables a humanitarian disaster response.     

Status cataplecticus induced by abrupt withdrawal of clomipramine

Introduction: Cataplexy is one of the main narcoleptic symptoms and is characterized by sudden loss of muscle tone triggered by emotional stimuli while consciousness is mantained. Clomipramine is an effective treatment of cataplexy. Cataplexy that occurs repeatedly for hours or days is referred to as status cataplecticus.Patients: We report three adults with narcolepsy in whom cataplexy was chronically and effectively treated with clomipramine (75-150 mg/day). For diverse reasons, these three patients had an abrupt withdrawal of clomipramine, and after 2-9 days patients showed an invalidant status cataplecticus characterized by a marked increase of the frequency, duration and severity of their cataplectic attacks that were now elicited by mild emotional stimuli. After introduction of anticataplectic agents (clomipramine in two patients and fluoxetine in one patient), status cataplecticus was resolved in less than a week.Conclusion: In patients with narcolepsy, abrupt withdrawal of chronic treatment with clomipramine may be associated with status cataplecticus. This condition may be resolved with the reintroduction of anticataplectic agents.     

Pericardial effusion complicating a percutaneous central venous line in a neonate

A premature infant developed pericardial effusion four days after the insertion of a 25-gauge silastic percutaneous central venous catheter. The effusion contained parenteral nutrition fluid and resolved rapidly after withdrawal of the catheter. Pericardial effusion is a potential complication of percutaneous, as well as surgically placed, central venous catheters.     

Nasal inflammation and chronic ear disease in Australian Aboriginal children

Objective : Chronic middle ear disease is common in Aboriginal children, and may be linked to nasal inflammation and Eustachian tube dysfunction. The pattern of nasal inflammation is unknown. The study reported here was performed to define the role of allergy and infection in causing nasal inflammation in Aboriginal children with chronic middle ear disease.
Methodology : Thirty-one Aboriginal children aged between 3 and 7 years underwent clinical assessment, audiometry and allergy skin tests. Nasal swabs for bacterial culture and cytology were performed during the winter and again in spring to identify any seasonal variation. A randomized trial of nasal beclomethasone for 8 weeks was conducted in children with abnormal tympanometry to identify the effect of therapy upon nasal cytology.
Results : Twenty-six of the 31 children had abnormal tympanograms. Average hearing levels were reduced in nine children. Pathogenic organisms were isolated from most children: Streptococcus pneumoniae (82%), Haemophilus influenzae (79%), Moraxella catarrhalis (39%) and Staphylococcus aureus (29%). Eight of the 31 children (26%) were atopic. Nasal cytology disclosed a marked neutrophil infiltrate (80% of cells) during the winter, which fell significantly in spring to 52% of cells. Only two subjects had nasal eosinophilia of >10%. There was no effect of beclomethasone on nasal cytology.
Conclusions : Chronic ear disease in Aboriginal children is associated with nasal inflammation, neutrophil infiltration and the presence of bacteria. These features suggest respiratory infection as the main cause of chronic nasal inflammation in Aboriginal children with middle ear disease. There is a seasonal variation in the severity of the nasal infiltrate, consistent with increased infections during winter. Despite a high prevalence of atopy, allergic nasal disease was uncommon.     

Histidinaemia: a benign metabolic disorder

Histidinaemia is a relatively common inherited metabolic disorder with an incidence similar to phenylketonuria. This paper reports the long term outcome of patients diagnosed by newborn screening in the north west of England. Between 1966 and 1990, 108 infants were diagnosed as having histidinaemia by a regional neonatal screening programme (incidence 1:11,083). A further five children were detected following diagnosis in a sibling. Of the 113, nine were lost to follow up. Infants diagnosed before 1981 (n = 47) were placed on a low histidine diet (225 mg/kg/d) for an average period of 21 months (SD 4.5). All patients were reviewed regularly, Griffiths developmental quotients (DQ) were assessed at 2 and 4 years, and WISC-R intelligence quotients (IQ) at 8, 12, and 18 years. IQ data were converted to standard deviation scores (IQ SDS) to account for increasing IQ norms with time. Neither DQ nor IQ correlated with plasma histidine at diagnosis or with the mean plasma histidine throughout life. Growth was normal in all patients. There was no apparent benefit from a low histidine diet in early childhood. In contrast to other studies, there was no excess of clinical symptoms. On the basis of these findings, histidinaemia is a benign metabolic disorder that does not require treatment.     

Evaluation of neurodevelopmental outcome in highrisk infants in Australia

An understanding of the neurodevelopmental outcome of long-term survivors of neonatal intensive care is essential for the informed management of preterm or high risk infants. This annotation looks at the current status of neonatal follow-up services in Australasia and highlights problems in the collection and interpretation of data. It suggests that we should work towards achieving a consensus on standard definitions and test regimes and on national data collection.     

Adult height in patients with childhood onset atopic dermatitis

Cross sectional studies have reported impaired growth in children with atopic dermatitis. If this growth impairment is irreversible, it would be expected to adversely influence final height attainment. The standing heights and other anthropometric parameters were assessed in 35 adults with onset of atopic dermatitis before 5 years of age and a control group of 35 adults with adult onset contact dermatitis or psoriasis. There was no significant difference in the standing height SD score, mid-parental height SD score, sitting height SD score, subischial leg length SD score, nor body mass index between the atopic dermatitis and control groups. The standing height SD score was not significantly different among: (a) patients with atopic dermatitis affecting less than 50% of their body surface area and those with greater than 50% affected; (b) patients using the four different potency topical corticosteroids; and (c) patients with atopic dermatitis without asthma and those with coexisting asthma. It is concluded that short stature is not a feature of our group of adult patients with onset of atopic dermatitis before 5 years of age, continuing into adulthood, and severe enough to require specialist care. This suggests that if growth impairment occurs in childhood, it is likely to be temporary and reversible.     

Bilateral acute confluent disseminated choroiditis in Borrelia burgdorferi infection

Two patients with bilateral extensive confluent choroidal lesions, exudative retinal detachments, positive lyme serology and a typical history are documented: A 32-year-old woman presented 14 days after a "flu-like" illness with bilateral acute extensive choroidal lesions and exudative retinal detachments (OD from 5 to 8:30 o'clock, OS from 5 to 8 o'clock, both including the macula) accompanied by a mild lymphocytic meningitis. The laboratory work-up revealed increased serum and CSF titers of antibodies against Borrelia burgdorferi (Lyme immunofluorescent test (IFT) and Lyme-IgM IFT) which declined after a 14-day treatment with doxycycline (200 mg/d), CSF titers non-detectable (serum IgG: from 1:640 to 1:320, serum IgM: from 1:40 to 1:20). A distinct improvement with visual acuity increasing from OD 0.2/OS 0.3 p to OD/OS 0.8 p was observed after seven days of treatment. A 40-year-old man with a 14-day history of tick-bite developed the same, though more severe ocular findings and a lymphocytic meningitis. The serological work-up revealed increased antibody titers against Borrelia burgdorferi (ELISA); the IgM titer was normal. After a 10-day treatment with penicillin, antibody titers against the spirochete decreased slightly and the patient's neurologic and ophthalmologic status improved dramatically. Five weeks after admission visual acuity was OD/OS 0.5 (compared to OD/OS 0.1) and has remained at 0.8 p (OD/OS) since the ninth week after onset. The clinical course of the disease and the decreasing lyme serology strongly suggest an infection with Borrelia burgdorferi. The authors propose thorough laboratory work-ups including tests for Lyme disease in selected patients with diffuse choroidal lesions.
