Motor Development of Premature Infants Born between 32 and 34 Weeks.

Little is known about motor development in late preterm born infants. Our objective was to determine long-term outcome of motor skills of infants born between 32 and 34 weeks. All infants were assessed at corrected ages of 3 and 9 months, using the Alberta Infant Motor Scale. At corrected ages of 4 years, the Movement Assessment Battery for Children was done. Seventy infants were seen at 4 years of age (median of 3 assessments per infant). Abnormal assessment at 3 or 9 months of age resulted in normal outcome in almost 80% at 4 years. On the other hand, a normal outcome in the first year of life resulted in an abnormal outcome at 4 years in 10% of the infants. Our results suggest that long-term followup of these late preterm born infants is necessary, as the assessments in the first year do not predict the long-term outcome.

A comparative cohort study on transfusion practice and outcome in two Dutch tertiary neonatal centres.

The objective of this study was to investigate how a red blood cell transfusion volume of 15 or 20 mL kg(-1) body weight affects the total number of administered transfusions and neonatal complications in premature infants born before 32 gestational weeks. In this observational study, we analysed clinical data from two cohorts of 218 and 241 premature infants admitted to two neonatal centres which used the same transfusion guideline and product, but different transfusion volumes. Outcome parameters were the number of administered transfusions and the composite outcome of bronchopulmonary dysplasia, retinopathy of prematurity, intraventricular haemorrhage and mortality. The proportion of transfused infants was significantly lower (59 vs. 77%) in the centre using a lower transfusion volume of 15 mL kg(-1). In infants born between a gestational age of 24 0/7 weeks and 27 6/7 weeks. a similar proportion received transfusions in both centres, with an equal number of transfusions per infant. In infants born between a gestational age of 28 0/7 weeks and 31 6/7 weeks, the proportion of transfused infants (49 vs. 74%) was significantly higher in the centre using a larger transfusion volume. In these infants, transfusion with 20 mL kg(-1) resulted, however, in a mean reduction of one transfusion episode per infant. The higher proportion of transfused infants was associated with a higher pre-transfusion haematocrit in less ill infants, suggesting the use of different triggers based on clinical grounds. Composite clinical complications were similar in both cohorts. Clinical neonatal outcome was similar disregard of a higher proportion of transfused patients and a higher total amount of RBC transfused in one of the centres. A larger transfusion volume of 20 mL kg(-1) prolonged the interval until next transfusion and can reduce donor exposure in infants born between a gestational age of 28 0/7 weeks and 31 6/7 weeks.

[Need for blood transfusion in premature infants in 2 Dutch perinatology centres particularly determined by blood sampling for diagnosis]. / Bloedtransfusiebehoefte bij prematuren in 2 Nederlandse perinatologische centra sterk bepaald door bloedafname voor diagnostiek.

OBJECTIVE: Determination of factors related to the need for transfusion in premature infants. DESIGN: Descriptive. METHOD: The need for transfusion in premature infants was determined in 2 academic centres: University Medical Center Utrecht and Leiden University Medical Center, The Netherlands. The data had been acquired in another study. The factors under study were: hospital, pregnancy duration, birth weight, gender, time of clamping of the umbilical cord, total volume of blood sampled for diagnostic purposes, number of days of mechanical ventilation, total duration of admission and duration of the admission to the Neonatal Intensive care unit. Both hospitals followed the national interdisciplinary practice guideline 'Blood transfusion'. RESULTS: The total volume ofsampled blood for diagnosis, the duration of the mechanical ventilation and the admission period were related to a greater need for transfusion. On the other hand, the chance of transfusions diminished with longer pregnancy duration or increased birth weight. The difference in need for blood transfusion between both centres was significant. The total volume of transfused erythrocytes showed a strong correlation with the volume sampled for diagnostic procedures. CONCLUSION: Anaemia in neonates is strongly related to the amount of blood taken for diagnostic procedures. Alternatives for blood transfusions in premature infants, and consequently for the reduction of the number of donors per child, are to be sought in delayed clamping of the umbilical cord, use of erythropoietin and use ofautologous umbilical cord blood.

Diagnosis and management of cervical teratomas.

We present three cases of cervical teratoma, two of which were detected prenatally by ultrasound. The two cases diagnosed prenatally showed rapid early growth, which indicated the aggressive nature of the tumour and assisted the parents' decision to terminate the pregnancy. The third case was undiagnosed prenatally and the child was born after a normal pregnancy and uncomplicated vaginal delivery. She recovered well after excision of the teratoma.

Predictive variables for the biological behaviour of basal cell carcinoma of the face: relevance of morphometry of the nuclei.

We did a morphometric analysis of 130 histological sections of basal cell carcinoma (BCC) of the face to find out whether morphometric variables in the structure of the nuclei of BCC cells could serve as predictors of the biological behaviour. We considered the following variables: maximum and minimum diameters, perimeter, nuclear area and five form factors that characterise and quantify the shape of a structure (axis ratio, shape factor, nuclear contour index, nuclear roundness and circumference ratio). We did a statistical analysis of primary and recurring tumours and four histology-based groups (multifocal superficial BCCs, nodular BCCs, sclerosing BCCs and miscellaneous forms) using a two-sided t test for independent samples. Multifocal superficial BCCs showed significantly smaller values for the directly measured variables (maximum and minimum diameters, perimeter and nuclear area). Morphometry could not distinguish between primary and recurring tumours.

[Possible complications in arthroscopic lavage of the temporomandibular joint]. / Mögliche Komplikationen bei der arthroskopischen Lavage des Kiefergelenks.

COMPLICATIONS: Arthroscopy of the temporomandibular joint is an invasive procedure that can entail potential complications. Based on many years of personal experience and taking data from the literature into account, this article discusses functional, surgical, and anesthesiological complications of arthroscopy of the temporomandibular joint. The majority of these complications can be avoided by heeding specific knowledge of topography, careful manipulation, and corresponding surgical experience. INFORMING THE PATIENT: The information given to the patient prior to the intervention should cover not only hemorrhaging, swelling, and wound infection, but also damage to (branches of) the facial nerve, the risk of perforation of the auditory canal as well as the possibility of temporary occlusal disturbances.

Tissue expansion using osmotically active hydrogel systems for direct closure of the donor defect of the radial forearm flap.

Although widely used, the radial forearm flap has been criticized for the poor quality of its donor site. Attempts to avoid donor-site problems have concentrated on the elaboration of the split-thickness and full-thickness skin graft methods of reconstruction. Skin grafts frequently fail over the flexor carpi radialis tendon, leading to chronic skin breakdown or, at best, tendon adhesion. Tissue expansion appears to be a good alternative that allows the use of local tissues to ultimately improve the forearm donor-site appearance. To avoid the disadvantages of traditional silicone balloon expanders (such as pressure peaks, infection, the valve at a distance from the expander, postoperative fillings), an osmotically active system was used. In an 18-month prospective study, 10 osmotically active hydrogel tissue expanders were placed on the forearms of 10 patients. The radial forearm flap was performed for intraoral reconstruction after surgical resection of oral cavity malignancies. The study showed that, in nine out of 10 patients, the expanded skin achieved was sufficient to cover the donor site after raising the forearm flap. Additionally, the expansion-related swelling pressure was well tolerated by the patients, the cosmetic results were very satisfactory, and the incidence of complications was very low. By using osmotically active hydrogel tissue expanders, there is no postoperative filling and no risk of complications arising from defective balloon expanders, filling valves, or missing ports.

Type A botulinum toxin in the treatment of chronic facial pain associated with temporo-mandibular dysfunction.

In an open-label study 41 patients suffering from the muscular form of temporo-mandibular dysfunction were treated with botulinum toxin type A injections into masticatory muscles (average of 200 U on each side) and followed for an average of 6.7 months. Eighty percent of patients improved by a mean reduction of 45% on a visual analogue pain scale. During the observation period, 17% of patients had to receive a second injection because of recurrent pain. Reversible speech and swallowing difficulties occurred in only 1 patient. These encouraging results need to be confirmed by a randomized controlled trial.

Type A botulinum toxin for the treatment of hypertrophy of the masseter and temporal muscles: an alternative treatment.

The treatment of hypertrophy of the masseter and temporal muscles has to date been dominated by conservative and surgical measures. Local therapy with type A botulinum toxin permits an alternative method of treatment. After targeted, sometimes electromyographically controlled, intramuscular injection of the affected muscles, marked inactivity atrophy occurred in the muscles of seven patients over the course of 3 to 8 weeks. This atrophy remained constant over a follow-up period of up to 25 months, and no side effects were observed. Because of its minimal invasiveness, this technique seems to have an advantage over conventional surgical therapy. Consequently, treatment with type A botulinum toxin can be regarded as a sensible alternative to surgery in cases of hypertrophy of the masseter and/or temporal muscles.

Fetal cleft lip and palate: sonographic diagnosis, chromosomal abnormalities, associated anomalies and postnatal outcome in 70 fetuses.

OBJECTIVE: The aim of this study was to determine the relationship between facial clefts, associated malformations and chromosomal abnormalities. STUDY DESIGN: Sonograms of 70 fetuses with cleft lip with or without cleft palate were prospectively and retrospectively evaluated in our tertiary referral center for the nature of the cleft lip or palate and for the nature of the associated anomalies. Additionally, karyotyping was performed in 63 of the 70 patients (90%). RESULTS: The frequency of additional anomalies and the mortality rate in this selected population varied with the type of cleft. None of the fetuses presenting an isolated cleft lip had additional anomalies and all survived. All fetuses presenting a median facial cleft had concurrent anomalies (particularly of the central nervous system (90%)) and a fatal outcome. Associated defects were more frequent in fetuses with bilateral clefts (72%) than in those with unilateral clefts (48%). Fetuses with a unilateral cleft lip with or without cleft palate had a better survival rate (52%) than those with a bilateral cleft lip with or without cleft palate (35%). The frequency and type of chromosomal abnormalities varied with the type of cleft. The highest rate of chromosomal abnormalities was found in fetuses with median clefts (82%). CONCLUSIONS: Although no conclusions regarding the prevalence of chromosomal or other anomalies in patients with a cleft lip with or without cleft palate in the general population could be drawn, the study revealed a strong relationship between the type of facial cleft, associated malformations, chromosomal abnormalities and fetal outcome.

Frey syndrome: treatment with type A botulinum toxin.

BACKGROUND: Frey syndrome was first described by Baillarger in 1853. Frey provided a detailed analysis and description as "auriculotemporal syndrome" in 1923. According to the literature, even the most recent therapeutic measures described for the treatment of patients with Frey syndrome have little chance of success and a high incidence of side effects. Thus, a type of treatment is desirable that can suppress the symptoms of Frey syndrome and can offer a good success rate, minimum invasiveness, and few side effects. METHODS: The experience of the authors and data from the literature confirmed the efficacy of type A botulinum toxin treatment for patients with Frey syndrome up to a maximum observation period of 3 years. RESULTS: In the current study, seven patients with severe, symptomatic Frey syndrome after parotidectomy were treated successfully with type A botulinum toxin. CONCLUSIONS: The method of local, intracutaneous treatment with type A botulinum toxin for patients with Frey syndrome is effective, virtually side-effect free, and minimally invasive.

[Value of computerized tomography and magnetic resonance tomography in diagnosis of malignancies of the mouth cavity and oropharynx]. / Stellenwert von Computertomographie und Magnetresonanztomographie bei der Diagnostik von Malignomen der Mundhöhle und des Oropharynx.

PROBLEM: There is a lack of clear criteria for the use of MR and CT in the diagnosis of head and neck cancer--some of it is even contradictory. The results of this study should lead to the establishment of more clear criteria. PATIENTS: 165 patients suffering from head and neck tumors were subjected to a total of 463 CT and 197 MRI examinations. RESULTS: The CT and MRI staging corresponded in 67% and 60% of the oropharynx tumors, respectively, with the clinical findings. In the case of oral cavity tumors, the clinical TNM stages were identical with CT and MRI results in 50% and 43% of cases, respectively. In the case of lymphatic node staging, the frequency of error was slightly higher using MRI, at 27%, compared with the CT rate of 22%. In the evaluation of cervical lymphatic nodes, CT proved to be more sensitive attaining 78% compared to the MRI rate of 69%. CONCLUSION: The results provide clear indications as to the MRI and CT examinations. Primary preoperative screening and post-therapeutic aftercare should be assessed using CT, as should lymphatic node diagnosis in the neck area. In the case of special problems such as, for example, the relevant bone and periostium infiltration, MR should be considered as a supplementary examination at a second stage.

Staged operations for basal cell carcinoma of the face.

211 patients (88 female, 123 male, mean age 63 years) presented with 279 basal cell carcinomas (191 primary tumours, 88 recurrent tumours) in the head and neck area that were excised. The resected margins were examined microscopically and the defect repaired at a second operation. The excision margin was 1-2 mm. The recurrence rate was 3%, which is lower than is achieved by other methods, and unaffected structures are optimally conserved.

Duane retraction syndrome, a new feature in 22q11 deletion syndrome?

A female child with Duane retraction syndrome is described. A microdeletion on chromosome 22(q11) was discovered using FISH analysis. It is postulated that Duane retraction syndrome might be a new feature in 22q11 deletion syndrome.

Tooth-borne distraction to widen the mandible. Technical note.

Based on reported animal studies, the case report presented demonstrates the use of tooth-borne distraction osteogenesis for mandibular widening of 1 cm in order to avoid extraoral distraction devices. Detrimental side effects on healthy anchoring teeth are not likely.

Salivary gland involvement as an initial presentation of Wegener's disease. A case report.

The case is presented of a 47-year-old woman with an 8-week history of persistent right ear discomfort and a 2-week history of unilateral parotid swelling, as well as peripheral paresis of the facial nerve. The case points to the difficulties encountered when Wegener's granulomatosis presents in an unusual and varied way which mimics a malignant tumour of the parotid gland. To our knowledge, the association of parotid gland involvement and facial palsy in Wegener's granulomatosis has not previously been described in the literature.
