[Speech rehabilitation following laryngectomy with the Blom-Singer prosthesis].

The Blom-Singer prosthesis was used on 18 male patients. 61% of these acquired fluent speech, 11% spoke partially and 28% were not able to use the prosthesis at all. Complications included dysphagia and difficulties with the function of the prosthesis. In some cases surgical revision or removal of the prosthesis was necessary. Older patients and those living in poor social conditions should not be selected for this procedure as their cooperation and motivation often seem to fail.

Pharmacokinetic evaluation of haemoperfusion in phenobarbital poisoning.

Charcoal haemoperfusion was performed for 5-12 h in three patients with maximal plasma phenobarbital concentrations of 600, 946 and 1044 mumol/l (138, 217 and 240 micrograms/ml). During haemoperfusion with constant blood flow phenobarbital elimination followed first order kinetics with half-lives of 11.1, 10.0 and 7.2 h, respectively. After termination of the haemoperfusion there was no rebound effect in plasma phenobarbital concentration and the elimination was first order with half-lives of 51, 82 and 48 h, respectively. Thus, the plasma phenobarbital half-life was reduced by 78-88% during haemoperfusion. In the same period 76-86% of the total body clearance of phenobarbital was due to the haemoperfusion column at a calculated volume of distribution of phenobarbital of 1.1-1.21/kg. This is clear evidence for recommending haemoperfusion in cases of serious poisoning with phenobarbital.

Sialography and CT-sialography in the diagnosis of parotid masses.

Parotid masses were evaluated by sialography and CT-sialography in 22 patients. Nineteen were benign tumors and one a metastasis. All were identified by CT. Two patients with sialoadenitis were misinterpreted at CT. All benign tumors appeared as lobulated, sharply marginated masses, embedded in displaced glandular parenchyma. The metastasis was lobulated, irregular and located within the gland. With sialography, 17 tumors were identified and 3 small superficial tumors overlooked. Both patients with sialoadenitis were diagnosed by sialography. CT-sialography is recommended in patients with suggested parotid masses, and sialography in suggested inflammatory disease.

Hypernephroma and hypertension. Two case reports.

Evaluation for hypertension revealed a hypernephroma in two patients and increased plasma renin concentrations (PRC) of 2.8 and 3.1 GU . 10(-4)/ml, respectively. In one of the patients, bilateral renal venous catheterization showed lateralization of PRC toward the tumor side in the ratio 10:3. She had secondary hyperaldosteronism with a plasma aldosterone concentration (PAC) of 738 pmol/l, and hypokalemia with a serum potassium level of 3.0 mmol/l. In the other patient, who had malignant hypertension, PAC was not measured but serum potassium was subnormal (3.3 mmol/l). After nephrectomy, blood pressure (BP), PRC and serum potassium returned to normal in both as did PAC in one of the patients. At regular follow-ups through one year after nephrectomy, BP, PRC, PAC and serum potassium remained normal and metastases were not discovered. The increased incidence of hypernephroma in hypertensive patients underscores the importance of acknowledging this possibility during evaluation for hypertension.

Productivity improvement and job satisfaction among public health nutritionists.

A workshop for public health nutritionists which scrutinized ways to improve productivity and job satisfaction is reported. Participants believed that productivity could be improved most by improving the execution of tasks, followed by better planning of programs, office management, and skills in group education, and by delegation of non-professional activities to lesser-trained personnel. Job satisfaction of public health nutritionists could be increased by reducing stress and discomfort and promoting feelings of personal effectiveness and efficiency through role clarification and by management training. There is a large potential for greater productivity in the profession. Realization of this potential will contribute measurably to the cost-effectiveness of nutritional services.

[Development of dentition 4 to 6 years of age].

A longitudinal study has been made of the incidence of caries and malocclusion in 361 high-risk children and 180 control children aged between 4 and 6 years. A comparison of the findings obtained from the two groups showed no remarkable differences in the two areas of examination.
