A child with signs of developmental apraxia of speech with whom a palatal lift prosthesis was used to manage palatal dysfunction.

A client is described who exhibited a large number of characteristics consistent with developmental apraxia of speech (DAS). The exhibited symptoms included excessive nasal resonance and nasal emission of air due to velopharyngeal port dysfunction, for which successful management was achieved by use of a palatal lift prosthesis. The results of the client's use of the lift, in conjunction with her speech and language remedial programming, is presented.

Retroperitoneal fibrosis in two patients with Parkinson's disease treated with bromocriptine.

Retroperitoneal fibrosis has been observed in two patients with Parkinson's disease treated with bromocriptine. The patients complained of abdominal or lower back pain and presented with various degrees of renal insufficiency, with anuria in one. Laboratory evaluation furthermore showed an increased sedimentation rate and inflammatory anemia. Computerized tomography disclosed marked retroperitoneal thickening, and biopsy was performed in one patient. The symptoms appeared eighteen months and five years after treatment was started, at doses of 20 and 22.5 mg of bromocriptine daily. The medication was discontinued in both patients and steroid therapy was initiated, with resolution of all clinical, biological and radiological evidence of disease. This potential but rare complication of a widely prescribed drug warrants monitoring of renal function and sedimentation rate in patients undergoing bromocriptine treatment.

Toxin production by strains of Aeromonas hydrophila grown in laboratory media and prawn purée.

Toxin production by four strains of Aeromonas hydrophila grown at 30 and 37 degrees C in two laboratory media and prawn purée was studied. Three different cell lines were used to test for cytotoxic activity, haemolytic activity was tested against rabbit and guinea pig erythrocytes, proteolytic activity was assayed with azo-casein and enterotoxic activity using the suckling mouse assay. Results showed reduced cytotoxic and haemolytic activities in prawn purée compared with the two media, but in most cases increased proteolytic activity. No enterotoxic activity was observed in prawn purée although it was occasionally detectable in both laboratory media.

The concurrent validity of the Minnesota Child Development Inventory as a measure of young children's language development.

The extent to which the Minnesota Child Development Inventory (MCDI), could be used to estimate levels of language development in 2-year-old children was examined. Fifty-seven children between 23 and 28 months were given the Sequenced Inventory of Communication Development (SICD), and at the same time a parent completed the MCDI. In addition the mean length of utterance (MLU) was obtained for each child from a spontaneous speech sample. The MCDI Expressive Language scale was found to be a strong predictor of both the SICD Expressive scale and MLU. The MCDI Comprehension-Conceptual scale, presumably a receptive language measure, was moderately correlated with the SICD Receptive scale; however, it was also strongly correlated with the expressive measures. These results demonstrated that the Expressive Language scale of the MCDI was a valid predictor of expressive language for 2-year-old children. The MCDI Comprehension-Conceptual scale appeared to assess both receptive and expressive language, thus complicating its interpretation.

Patient administration: one-step patient processing.

As the healthcare industry becomes increasingly concerned about efficiency and cost effectiveness, healthcare organizations are looking for methods of consolidating and integrating operations. One area where consolidation can occur is patient administration. Patient administration is the total functional, informational, organizational, and structural consolidation of patient accounting, registration, admitting, medical records, and other patient-generated clerical activities in the hospital or ambulatory clinic. It is a method of maximizing the delivery of healthcare services at minimum cost.

[Prostate hypertrophy. Surgical experience in Belgium. Multi-center study of 1,140 patients of 80 years and older].

An inquiry organized by the Belgian Society of Surgery brought data on the mortality and morbidity of surgery on patients of 80 years and older for benign prostatic hypertrophy in a total number of 1,140 operations. Consensus exist to see this surgery as planned surgery. The mortality was 73 (6.3%) without statistical difference between endoscopic and open surgery. The morbidity of 824 patients was 165. This last figure relates to the big series in the literature. The mortality is in direct relation to the age of the patients. Evaluation of cardio-pulmonary risk (70.8% of the mortality), operation on indication at earlier diagnosis and prospective studies on the risk of operation in this population group are indicated.

Mutagenic and tumourigenic properties of the spores of Aspergillus clavatus.

Spore walls of a sputum-derived isolate of Aspergillus clavatus yielded mutagen(s) when their extracts were fractionally precipitated with ethanol following alkaline hydrolysis. After spores were given by nasal inoculation to 6-8-week-old CF-1 mice, light and electron microscopy of lung sections showed that they had been readily phagocytozed by the polymorphonuclear leucocytes and alveolar macrophages mobilized during early allergic alveolitis in immunized mice. The formation of phagosomes was followed in thioglycollate-stimulated peritoneal macrophages grown in vitro. Unimmunised mice showed a comparable lung reaction, attributed to pulmonary mycotoxicosis, and revealed a rising incidence of lung tumours, from 25% at 2 months from inoculation, to 27.3% at 6 and to 55.5% at 8. Mean numbers of tumours per lung rose from 1.0 to 2.2. Total tumours, including lymphomas, reached a final incidence of 77.7% at 8 months, when control animals were tumour-free. Tumour development correlated with the retention of apparently intact spores within giant cells probably derived from aggregates of alveolar macrophages. The implications of these findings in the light of the known history of human exposure to such spores is discussed.
