The diagnosis of Dubowitz syndrome in the neonatal period--a case report.

We present an infant with Dubowitz syndrome diagnosed at birth and followed for 2 years. Presence of the syndrome was suspected at birth on the basis of the anthropometric data and peculiar facial appearance. However, during the follow-up period some changes in the appearance have taken place. It is suggested that the neonatal anthropometric measurements are important diagnostic criteria for Dubowitz syndrome.

Spastic paraparesis, mental retardation, and cutaneous pigmentation disorder. A new syndrome.

Four siblings in a family with a highly consanguineous background presented with an unusual combination of spastic paraparesis, muscle wasting, microcephaly, mental retardation, skeletal deformities, and cutaneous manifestations, ie, hypopigmented and hyperpigmented lesions and graying of the hair. An extensive workup including electromyography, muscle biopsy, and chromosomal analysis was unrewarding. An autosomal recessive inheritance is probable. A similar entity was recently reported from israel. The possibility that this previously unrecognized condition represents a new syndrome is suggested.

Licensed lay midwifery and the medical model of childbirth.

Previous research has tended to equate lay midwifery with demedicalized care. This paper analyzes how licensed lay midwives in Arizona have been pressured towards a more medical model of childbirth. Licensing has affected midwives' beliefs and practices through increasing their exposure to medical definitions of childbirth and making them legally accountable to the medically dominated State Department of Health Services. The midwives' cumulative experience with handling obstetrical problems has also affected their definitions of childbirth. The midwives have maintained a commitment to holistic care, but have moved towards a more hierarchical style of practice due to changes in their clientele, the need for efficient bureaucratic arrangements, and the desire to earn a living at midwifery.

Carbamazepine-induced hair loss.

An 8 1/2-year-old girl was treated with carbamazepine because of headaches and electroencephalogram findings compatible with multifocal epilepsy. Within a week of drug initiation, hair shedding started. This continued until the drug was stopped, when new hair growth resumed. The hair loss was associated with carbamazepine serum concentrations lower than the therapeutic range.

Neuroendocrine study of a male infant with septo-optic dysplasia.

Septo-optic dysplasia includes abnormalities of the optic nerves and tracts with absence of the septum pellucidum. Most of the recently reported patients were deficient in growth hormone. We describe a male infant with septo-optic dysplasia in whom extensive endocrine evaluation revealed central diabetes insipidus, hypothalamic hypothyroidism and combined (hypothalamic-pituitary) hypoadrenalism, along with normal pituitary growth hormone reserve. This is the first reported case of a patient with septo-optic dysplasia who underwent corticotropin-releasing factor and growth hormone-releasing hormone stimulation.

Obstacles to the practice of licensed lay midwifery.

Intensive interviews with licensed lay midwives in one of ten states that have recently reactivated and revised legislation legalizing such alternative practitioners for low risk clientele revealed a number of obstacles to their practice. The obstacles stem from the same rules and regulations developed by medical practitioners that made their homebirth service legal. Even after surmounting the difficulties of obtaining a license, the midwives find widespread unwillingness among private physicians to provide the required prenatal screening examination and medical back-up. The opposition of physicians to the licensed midwifery program is voiced in terms of concern about the safety of homebirths, particularly those attended by nonphysicians. Yet, the outcomes from the first 4 years of the program give no support for such concerns. Physician reluctance to cooperate with the legal program, combined with restrictions prohibiting the licensed midwives from suturing minor tears and administering a single dose of an antihemorrhagic drug in an emergency transfer, do compromise the overall quality of midwifery care. While accepting their subordinate position to medical practitioners, the midwives are struggling to establish the continuum of care for homebirth women implied in their licensure law.

Myocarditis and acute infantile hemiparesis. Case report.

A 13-month-old infant developed acute hemiparesis in the course of myocarditis. Cranial CT suggested occlusion of the right middle cerebral artery, and it is believed that an embolus arising from a mural thrombus is the most likely cause of the cerebral vascular accident. Anticoagulant therapy should be considered in myocarditis when myocardial ischemic damage or an intracavitary thrombus are suspected.

Convulsions in shigellosis. Evaluation of possible risk factors.

We studied 158 children with culture-proven shigellosis, 37 (23.4%) of whom had convulsions. Historical, clinical, and laboratory data were compared between patients with and without convulsions to define risk factors for the development of seizures. Age was the most important predisposing factor. The highest incidence of shigellosis associated with convulsions was found in children between 6 months and 4 years of age. Peak body temperature and a family history of convulsions also independently affected the development of seizures. Sex and Shigella strain showed differences between the groups but failed to reach statistical significance.

Segmental pigmentation disorder.

Pigmentary changes with a dermatomal distribution are described in 30 children. The disorder, up to now unrecognized as an entity, is apparently caused by an embryological determination. It is more obvious in children with darker skin, and seems to fade very slowly over the years. In our experience the incidence is 0.35%. No relation to other anomalies could be established.
