Those who can, do. Those who can't, teach.

A comparison of 4 methods of teaching introductory psychology underscored educational points concerning teachers' and undergraduates' expressed dissatisfaction with instruction. Bright students achieved more than duller students regardless of the teaching method used or student characteristics. Students' satisfaction with a course was a function of teachers' personal involvement with the course material. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Understanding the perceptions and experiences of faculty who teach multicultural counseling courses: An exploratory study.

Professional psychologists who teach multicultural counseling courses often face significant challenges, and very little information is available on their perceptions and experiences. A survey blending quantitative and qualitative questions was distributed to 169 faculty members who teach multicultural counseling courses. Results indicate that most faculty members surveyed typically incorporated self-disclosure when teaching and viewed their cultural identity as influential in how they teach. They also identified the specific teaching strategies they used and specified common group dynamics in class. Understanding the perceptions and experiences of faculty members who teach multicultural courses is essential to providing support for the important work done by these multicultural educators.

Lesbian mothers who conceived after donor insemination: a follow-up study

This study investigated the development of family relationships in lesbian families who conceived after donor insemination (DI). The main characteristics of this unknown family structure were analysed. An anonymous donor was used to conceive, the family unit consisted of two mothers and a father was non-existent, and both women had a homosexual orientation. A total of 50 lesbian couples who conceived after DI with children aged between 1 and 2 years participated in this study, using a standardized interview created for this study. After the birth of their child, 56% of the lesbian mothers (n = 100) would have wanted the identity of the donor to be registered, while 10% would have done so at the time of the insemination. Opinions differed in 12 of the 50 couples: the biological mother was in favour of identity registration while the social mother was not. Both women considered themselves a parent of the child with equally shared responsibilities. Mothers were open about the special features of their family structure with children and within their immediate social network. Only 30% disclosed their lesbian identity in a broader social environment. The features of these newly created families may influence the psychological development of the children and therefore make long-term follow-up studies indispensable.     

Indications and follow-up of total pelvic exenteration

Glucose-6-phosphate isomerase (GPI) deficiency, an autosomal recessive genetic disorder with the typical manifestation of nonspherocytic haemolytic anaemia, can be associated in some cases with neurological impairment. GPI has been found to be identical to neuroleukin (NLK), which has neurotrophic and lymphokine properties. To focus on the possible effects of GPI mutations on the central nervous system through an effect on neuroleukin activity, we analysed DNA isolated from two patients with severe GPI deficiency, one of them with additional neurological deficits, and their families. The neurologically affected patient (GPI Homburg) is compound heterozygous for a 59 A-->C (H20P) and a 1016 T-->C (L339P) exchange. Owing to the insertion of proline, the H20P and L339P mutations are likely to affect the folding and activity of the enzyme. In the second family studied, the two affected siblings showed no neurological symptoms. The identified mutations are 1166 A-->G (H389R) and 1549 C-->G (L517V), which are located at the subunit interface. We propose that mutations that lead to incorrect folding destroy both catalytic (GPI) and neurotrophic (NLK) activities, thereby leading to the observed clinical symptoms (GPI Homburg). Those alterations at the active site, however, that allow correct folding retain the neurotrophic properties of the molecule (GPI Calden).     

Total hip arthroplasty with cement in patients who have rheumatoid arthritis. A minimum ten-year follow-up study

One hundred and six consecutive total hip arthroplasties with cement were performed by one surgeon, at least ten years before the time of the present clinical and radiographic review, in seventy-five patients who had adult-onset rheumatoid arthritis. Two patients (three hips) were lost to follow-up. Seven (7 per cent) of the remaining 103 hips were revised. The revisions were performed because of infection (three hips), dislocation (two hips), or aseptic loosening (two hips). Of the ninety-eight hips that were not lost to follow-up or revised because of infection or dislocation, eight (8 per cent) had radiographic loosening of the acetabular component and two (2 per cent) had radiographic loosening of the femoral component. Although the prevalence of radiographic loosening of the acetabular component was four times greater than the prevalence of radiographic loosening of the femoral component, the prevalence of revision because of aseptic loosening of the acetabular component was identical to that for the femoral component (one component each). These results compared favorably with those of total hip arthroplasty with cement, performed by the same surgeon, for the treatment of other diagnoses. Loosening of the acetabular component was significantly associated with a younger age at the time of the index operation (p = 0.03) and with acetabular osteolysis (p = 0.0006). Of forty-eight hips in thirty-two patients who survived for at least ten years, 96 per cent (forty-six hips) were considered by the patients to have a satisfactory result. At the time of the latest follow-up, twenty-four (75 per cent) of the patients had no pain in the hip. Although eighteen patients (56 per cent) could walk without support at a minimum of ten years after the operation, we found that the functional results for patients who had rheumatoid arthritis were inferior to those observed for patients who had had a total hip arthroplasty with cement, performed by the same surgeon, for the treatment of other diagnoses.     

A follow-up study of Sydenham's chorea

Twenty-five patients convalescing from Sydenham's chorea were contrasted by clinical examination, electroencephalograms, and psychometric and psychologic tests to 15 siblings and 20 matched rheumatic fever controls. A group of 10 postchoreic patients who had two or more signs could be identified. Patients in this group had all the signs classified as moderate or severe, performed less well than other choreic subjects on the Bender gestalt test, and had a higher percentage of abnormal electroencephalograms but not a higher incidence of behavioral disorders. This subgroup could not be predicted from a review of neurologic history or from analysis of the acute episode of chorea. Our data would suggest that uncomplicated Sydenham's chorea is not necessarily a benign self-limited affliction of the central nervous system and that some patients are left with definite, albeit minimal, neurologic residua.     

Evaluation of a program to teach phonemic awareness to young children: A 1-year follow-up.

A follow-up of a study evaluating a program to teach young children about phonemic structure is reported. In the original study (B. Byrne and R. Fielding-Barnsley; see record 1992-10755-001), preschoolers were trained with the program for 12 wks and gained in phonemic awareness and knowledge of the alphabetic principle as compared with a control group. The children were retested at the end of kindergarten on phonemic awareness, word identification, decoding, and spelling. Children who entered school with advanced levels of phonemic awareness scored significantly higher on each of the measures. Alphabetic knowledge predicted literacy development, but phonemic awareness accounted for significant additional variance in decoding and spelling. Verbal intelligence did not influence reading and spelling performance. Other parts of the data led to the conclusion that some aspects of phonemic awareness may be a consequence of literacy instruction rather than a cause.

Treatment of non-resectable pelvic malignancies by isolated pelvic perfusion. A preliminary study

Management of non-resectable pelvic tumours by intra-arterial local chemotherapy was shown to be beneficial but systemic toxicity limits its use. To overcome this problem isolated pelvic perfusion (IPP) was introduced as an alternative. This study summarizes our preliminary experience with IPP in the treatment of 18 non-resectable pelvic tumours [recurrent rectal adenocarcinoma (six), soft tissue sarcoma (STS) (five), bone tumour (three), epidermoid carcinoma (two), prostatic adenocarcinoma (one), malignant melanoma (one)]. Results of IPP were regarded as complete remission (CR), partial remission (PR), stable disease (SD) and disease progression (DP) according to the changes in three parameters including; scoring in pain, tumour marker and tumour size measurements. Complete and partial remission were established in five (27%) and seven (39%) patients respectively indicating a benefit ratio of 66%. Objective pain relief was encountered in 53% of the cases. All patients with STS had undergone further surgical treatment after IPP with successful curative resections in four. No residual tumour was found at the laparotomy of the fifth patient. Presenting symptom of the prostatic adenocarcinoma patient was symptomatic hypoglycaemia which resolved completely after IPP. To our knowledge, this represents the first case reported in the English literature in whom tumour related hypoglycaemia was successfully managed by IPP. In conclusion; management of non-resectable pelvic tumours by IPP seems to offer serious palliation and increase in the quality of life without any systemic toxicity. Our preliminary experience suggests even resectability may be achieved in a number of patients especially in those with STS.

Recurrent ameloblastoma of the jaws. A follow-up study

Familial hyperproinsulinaemia is a rare genetic disorder characterized by point mutations in the insulin gene which impair the conversion of proinsulin to insulin. We report here three members of a two-generation Caucasian family in whom this syndrome was identified by unexplained hyperinsulinism associated with normal glucose tolerance and normal insulin sensitivity. Plasma insulin immunoreactivity showed a reduced affinity for the insulin receptor and eluted mainly, on Biogel chromatography, at the position of proinsulin. Analysis of the PCR-amplified insulin gene by restriction enzyme mapping revealed a new recognition site for the enzyme Nla III, indicating a Arg65 to His mutation. Sequence analysis of exon 3 confirmed this mutation in one allele of the gene. CONCLUSION: This study reports a two-generation European-Caucasian family with hyperproinsulinaemia due to a substitution of His for Arg at position 65 in proinsulin, the seventh now identified worldwide and the second from Europe. The mutation generated a new restriction site on the insulin gene suggesting the usefulness of restriction enzyme mapping as a screening procedure.     

Minilaparotomy staging pelvic lymphadenectomy follow-up: a safe alternative to standard and laparoscopic pelvic lymphadenectomy

Granulocyte transfusion therapy has been used infrequently in the last 10 to 15 years, in large part because its efficacy in the treatment of infected neutropenic patients has not been impressive. This perceived lack of efficacy has been attributed primarily to the fact that the dose of granulocytes obtainable with standard leukapheresis techniques has been inadequate. With the availability of recombinant granulocyte colony-stimulating factor (G-CSF) to stimulate neutrophilia in normal donors and increase the number of granulocytes that can be collected, there is now renewed interest in this form of transfusion therapy. Recent studies have shown that stimulation with G-CSF, with or without corticosteroids, is well tolerated by normal donors and that granulocyte yields are increased three- to four-fold. Blood neutrophil counts in patients receiving these large cell doses rise substantially, often to normal or near normal levels, and commonly remain elevated for 24 hours or more. In vitro and in vivo measurements have shown that the functional capabilities of granulocytes collected from G-CSF stimulated donors appear to be normal. Although early reports have been encouraging, the clinical efficacy of this new level of granulocyte transfusion therapy has been yet to be determined.     

Multiple osteocartilaginous exostosis. A follow-up study

In order to evaluate the results of voice and speech rehabilitation after total laryngectomy some acoustic parameters (fundamental frequency, waveform perturbation) were examined in 18 total laryngectomy patients. Eight of these subjects had previously been surgically rehabilitated with a tracheal-esophageal phonatory valve while 10 had been submitted to esophageal speech rehabilitation. Analysis of results has shown that tracheal-esophageal voices are more likely to provide a stable fundamental frequency; there is also a tendency toward more clearly defined harmonics; jitter and shimmer are more similar to the values of normal subjects compared with those observed in esophageal speech. Such results seem to depend on a more regular vibration pattern in the pharyngeal-esophageal segment, due to the more efficient expiratory flow in tracheal-esophageal speech. Moreover we were able to demonstrate a correlation between the objective parameters evaluated and the subjective score on speech acceptability.     

Recurrent intermetatarsal neuroma. A follow-up study

Sixteen patients were evaluated following excision of recurrent intermetatarsal neuroma. Each underwent removal of a segment of nerve through an incision on the plantar aspect. The nerve stump was buried in the flexor digitorum brevis muscle. At the time of follow-up examinations, six patients were asymptomatic, seven experienced mild pain after extended activity, one suffered mild consistent pain with activity, and two suffered pain that limited activities.     

Infantile eczema: A long-term follow-up study

A 15-17 year follow-up study was conducted on ninety-nine patients who had suffered from infantile eczema. The persistance of the eczema and the occurrence of related conditions were noted. The persistence of eczema was shown to be greater in those patients with a positive family history of eczema and in those who had developed asthma or hay-fever. An attempt was made to see if the persistence of eczema was affected by the position of the child in the family, and some factors provoking relapses were noted. The patients were also questioned with regard to their achievements in academic examinations, and to their social, artistic and sporting activities. The results showed a success rate in examinations not significantly higher than average. It was not possible to show if there is a particular type of atopic personality. There was no constant characteristic in social or artistic patterns. The group as a whole were normal at the milestones of early development, i.e. walking, talking and reading, and also normal with regard to weight and height.     

A 5-year follow-up study of suicide attempts

We reviewed 59 hips in 44 children with slipped capital femoral epiphysis (SCFE), all treated by in situ pinning. The average clinical and radiographic follow-up was 11.4 years. Fifty-three hips (90%) were rated as either excellent or good. Osteonecrosis or chondrolysis developed in five patients. Postoperative remodeling was noted, not only by a process of local resorption and apposition of bone, but also by correction of the disturbed anatomic axes, in proportion to the severity of the slip, together with global thickening of the femoral neck. We believe that the good long-term results after in situ pinning are the consequence of this important remodeling process.     

A longitudinal study of who seeks counseling when.

Determined at what time the members of a university freshman class who sought counseling initiated their contacts with counselors. Over the 4-yr period 401 males and 319 females sought counseling. In general, the rate of initiation declined steeply over time, both by years and by quarters within years. An occasional reversal occurred for females. Characteristics of the Ss as related to time of initiating counseling were also studied, utilizing scores on the School and College Ability Test, Omnibus Personality Inventory, and SVIB, administered in freshman orientation. Neither male nor female Ss differed significantly in test results when time of counseling initiation was considered by the 4 academic quarters. By year, quarter by quarter, and by parts of quarters, the Omnibus Personality Inventory yielded significant results on some scales. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
