Raised liver associated enzyme activity and post-prandial bile acid concentrations in sera from treated diabetic outpatients

Aspartate aminotransferase, alanine aminotransferase and gamma-glutamyl transferase activities were measured in sera from 411 diabetic outpatients and were raised in 26 (6.4%), 34 (8.3%) and 62 (15.2%) patients, respectively. Serum total bile acid concentrations were raised in 4 patients (1%). Percentage glycated hemoglobin A1, serum fructosamine concentration and plasma glucose concentration were also measured. No relationship between the presence of raised enzyme activity and mature age, short duration of diabetic treatment regimen or glycemic control was found. Twenty-six patients with an alanine aminotransferase activity greater than 60 U/l were reviewed at 23 +/- 6.5 weeks. The activity of this enzyme had fallen to within the reference interval in 15 (58%). In the other 11 patients, its median activity was 75 U/l (range 51-181 U/l). Median gamma-glutamyl transferase activity had risen in these 11 patients from 78 U/l to 93 U/l (P less than 0.01). No statistical differences in treatment regimen or glycemic control were found between these two groups. Raised liver-associated enzyme activity in treated stabilised diabetic outpatients should therefore not be attributed to poor glycemic control or diabetic treatment regimen.     

Gastrointestinal teratomas: CT and US appearance with pathologic correlation

Gastrointestinal teratomas are uncommon, benign neoplasms that occur primarily in children. A retrospective review of five cases (two gastric, one pancreatic, one mesenteric, and one in the lesser omentum) is presented with emphasis on the computed tomographic and ultrasonographic appearances. Principal findings are a well-defined mass with separate cystic and solid components of varying proportions, discrete areas with densities similar to that of fat, or coarse, globular calcifications within the solid component. Recognition of these findings may allow the radiologist to make a correct preoperative diagnosis of teratoma.     

Hypoglycemic convulsions cause serious musculoskeletal injuries in patients with IDDM

Six diabetic patients are described who sustained serious musculoskeletal injuries during insulin-induced hypoglycemia. The convulsions were associated with nocturnal hypoglycemia, superoptimal glycemic control, pregnancy, hypoglycemic unawareness, or errors in self-management.     

Symptoms of acute insulin-induced hypoglycemia in humans with and without IDDM. Factor-analysis approach.

OBJECTIVE: This study allocated the symptoms identified during acute hypoglycemia objectively to the autonomic or neuroglycopenic groups of symptoms by the use of factor analysis. RESEARCH DESIGN AND METHODS: Twenty-five nondiabetic subjects, 14 newly diagnosed insulin-dependent diabetic patients, and 16 insulin-dependent diabetic patients with diabetes greater than 4 yr duration were studied. Acute hypoglycemia was induced with insulin (2.5 mU.kg-1 body wt.min-1 i.v.), and symptoms of hypoglycemia were recorded with a seven-point scale at regular time points throughout the studies. Factor analysis of the symptom scores at the time of the acute autonomic reaction with principal component analysis followed by Varimax rotation was used to separate those symptoms that might belong to neuroglycopenic and autonomic groups. RESULTS: Hypoglycemia was induced to a mean +/- SE plasma glucose nadir of 1.3 +/- 0.1 mM in nondiabetic subjects, to 2.0 +/- 0.3 mM in newly diagnosed diabetic patients, and 1.4 +/- 0.2 mM in patients with diabetes of greater than 4 yr duration. The most frequently reported autonomic symptoms were sweating, trembling, and warmness, and the most frequently reported neuroglycopenic symptoms were inability to concentrate, weakness, and drowsiness. Neuroglycopenic symptoms were reported more commonly at the onset of hypoglycemia, which was identified by the development of symptoms. Factor analysis grouped trembling, anxiety, sweating, warmness, and nausea together, and this grouping was labeled an autonomic factor. A second factor was identified that included dizziness, confusion, tiredness, difficulty in speaking, shivering, drowsiness, and inability to concentrate, which was labeled a neuroglycopenic factor. CONCLUSIONS: This study demonstrated the high frequency with which neuroglycopenic symptoms occur at the onset of hypoglycemia and the symptoms that could be used by an individual patient as a warning of the development of acute hypoglycemia, although the rapid reduction of plasma glucose is faster than experienced by the ambulant diabetic patient. Factor analysis assisted with the allocation of symptoms to either the autonomic or neuroglycopenic groupings, but the allocation of some symptoms remained undefined, and care must be taken when assessing symptoms such as hunger, weakness, blurred vision, and drowsiness when comparing the frequency of autonomic versus neuroglycopenic symptoms. To reduce the confusion resulting from the use of different symptom questionnaires in studies of hypoglycemia, a sample questionnaire is presented, the development of which was assisted by our analysis.     

The community mental health nurse: a new professional role

This review of recent literature explores the similarities and differences between the work of community psychiatric nurses and their mental handicap counterparts. The comparisons which have been made between groups of nurses are related to the authors own research studies. These included an observations study of one community mental handicap nursing team and a national survey of all such teams in England and Wales. The importance of trade union membership, the place of the Community Psychiatric Nursing Association and the implication of joint training courses are discussed. The emergence of a new professional role that of the 'community mental health nurse' is discussed and the implications which this might have for the future organization of community psychiatric nursing services is outlined.     

Sense of coherence among elderly somatic patients: predictive power regarding future needs of care

The main aim was to study the predictive power of sense of coherence regarding future needs of care among elderly patients evaluated as medically ready for discharge from somatic emergency care. A secondary aim was to study the consistency of sense of coherence over time among patients with this kind of experience. The sample consisted of 53 Swedish patients (mean age 82.8 years, SD = 6.6 years) who had completed their medical treatment at surgical or orthopaedic departments. The predominant diagnosis was lower limb fractures. Sense of coherence was assessed twice, on the day the patient was evaluated as medically ready for discharge and 1 month later. On the second assessment occasion, 28 patients had returned to their homes, 17 were staying at institutions, and eight had died. Patients who returned to their homes reported the strongest sense of coherence while still in hospital. Patients who were staying at institutions scored lowest on the overall sense of coherence scale and on the comprehensibility subscale. Patients who died before the second measurement occasion scored lowest on the meaningfulness subscale. A correlation of 0.51 was noted between the two assessments of sense of coherence, indicating a moderate temporal consistency.
