Poor prognosis of young adults with type 1 diabetes: a longitudinal study.

OBJECTIVE: To determine the role of early behavioral and psychological factors on later outcomes in young adults with childhood- or adolescent-onset type 1 diabetes. RESEARCH DESIGN AND METHODS: We conducted a longitudinal cohort study of patients recruited from the register of the young adult outpatient diabetes clinic, Oxford, U.K. A total of 113 individuals (51 male subjects) aged 17-25 years completed assessments, and 87 (77%) were reinterviewed as older adults (aged 28-37 years). Longitudinal assessments were made of glycemic control (HbA(1c)) and complications. Psychological state at baseline was assessed using the Present State Examination and self-report Symptom Checklist, with corresponding interview schedules administered at follow-up. RESULTS: There was no significant improvement between baseline and follow-up in mean HbA(1c) levels (8.5 vs. 8.6% in men, 9.3 vs. 8.7% in women). The proportion of individuals with serious complications (preproliferative or laser-treated retinopathy, proteinuria or more severe renal disease, peripheral neuropathy, and autonomic neuropathy) increased from 3-37% during the 11-year period. Women were more likely than men to have multiple complications (23 vs. 6%, difference 17%, 95% CI 4-29%, P = 0.02). Psychiatric disorders increased from 16 to 28% (20% in men, 36% in women at follow-up, difference NS), and 8% had psychiatric disorders at both assessments. Baseline psychiatric symptom scores predicted follow-up scores (beta = 0.32, SE [beta] 0.12, P = 0.008, 95% CI 0.09-0.56) and recurrent admissions with diabetic ketoacidosis (odds ratio 9.1, 95% CI 2.9-28.6, P < 0.0001). CONCLUSIONS: The clinical and psychiatric outcome in this cohort was poor. Psychiatric symptoms in later adolescence and young adulthood appeared to predict later psychiatric problems.

Biologic characteristics of paragangliomas of the nasal cavity and paranasal sinuses.

Paragangliomas of the nasal cavity and paranasal sinuses are extremely rare. This study was conducted to investigate the biologic characteristics of these lesions on different molecular levels and to estimate their biologic behavior. Operative specimens of three patients who underwent surgery for a paraganglioma of the nasal cavity (one case) or paranasal sinuses (two cases) were investigated by routine histology, quantitative DNA analysis, and immunohistochemical assessment of proliferation markers (i.e., Proliferating Cell Nuclear Antigen, PCNA; Ki67-MIB-1), the expression of cell-surface antigens, which reflect the tumor-stroma interaction (i.e., CD 44 v0.4/5 and 6, CD 54, CD 106), oncogene products (nm-23; p53), and bcl-2 as a marker of apoptosis. Histologically, two tumors were paragangliomas of the adenomatous subtype, one lesion was classified as angiomatous. According to DNA analysis, aneuploid cells were detected in all tumors. Two of three paragangliomas were classified as a DNA type III pattern, implying a high percentage of aneuploid cells and an aggressive behavior. Immunohistochemically, paragangliomas of the nasal cavity showed increased scores for both proliferation markers tested, indicating a rapid growth pattern. According to the expression of cell-surface markers and oncogene products, these tumors displayed an aggressive behavior and an infiltrating growth pattern. The highest value for the parameters of quantitative DNA analysis and highest proliferation scores were found in a tumor of a patient who developed multiple tumor recurrences after radical excision of the lesion with clear margins, and finally died of disease. In conclusion, paragangliomas of the nasal cavity and paranasal sinuses examined in this study should be regarded as suspicious concerning their biologic and clinical behavior. Radical excision, and in cases with highly aggressive biology, postoperative radiation therapy are recommended. Tumor biologic examinations can help to recognize high-risk patients for developing recurrences and possibly lesions with a malignant behavior and to enhance our understanding of the biology of these extremely rare tumors of the nasal cavity and paranasal sinuses.

Outcomes of treated human granulocytic ehrlichiosis cases.

We conducted a case-control study in Wisconsin to determine whether some patients have long-term adverse health outcomes after antibiotic treatment for human granulocytic ehrlichiosis (HGE). A standardized health status questionnaire was administered to patients and controls matched by age group and sex. Consenting patients provided blood samples for serologic testing. Among the 85 previously treated patients, the median interval since onset of illness was 24 months. Compared with 102 controls, patients were more likely to report recurrent or continuous fevers, chills, fatigue, and sweats. Patients had lower health status scores than controls for bodily pain and health relative to 1 year earlier, but there was no significant difference in physical functioning, role limitations, general health, or vitality measures. The HGE antibody titer remained elevated in one patient; two had elevated aspartate aminotransferase levels. HGE may cause a postinfectious syndrome characterized by constitutional symptoms without functional disability or serologic evidence of persistent infection.

Chronic subdural haematoma: review of 96 cases attending the Korle Bu Teaching Hospital, Accra.

BACKGROUND: Chronic subdural haematoma is not uncommon in Africa. Early diagnosis and treatment is satisfying. Simpler operative procedures are generally effective. This review is meant to find out the situation regarding the condition in Ghana. STUDY DESIGN: A retrospective study of patients with chronic subdural haematoma admitted to and treated by the Neurosurgical Unit of Korle Bu Teaching Hospital between January 1995 and December 1998 was undertaken. The case notes, computerise axial tomography (CT) scans and operative records were reviewed and the relevant data extracted. Incomplete records were excluded. RESULTS: 96 patients were involved. The mean age of the patients was 46.9 years, with male to female ratio of 16:1. The most common presenting feature was headache (64.7%). Time of injury to presentation was about 2 months. 81 were treated using burr hole and drainage and 15 by craniotomy and stripping of membranes. Eighty four were treated under general anaesthesia. Two were reoperated on because of recurrent bleed. There were two (2) deaths. Ninety patients had a Glasgow Outcome Score of good at the time of their last review. CONCLUSION: The data suggests that burr hole and closed drainage is a very effective method of managing CSDH.

Our experience with the therapy of bleeding peptic ulcers.

Authors present their clinical experience gained in the therapy of bleeding peptic ulcers. The modified Baylor Bleeding Score has proved to be a reliable tool for assessing the risk of recurrent hemorrhage. Early introduction of H2-receptor blocker therapy is justified both in conservative as well as in surgical management of bleeding peptic ulcers.

Triple compartment prolapse: sacrocolpopexy with anterior and posterior mesh extensions.

Post-hysterectomy vault prolapse may be accompanied by anterior (cystocele) and posterior (rectocele) pelvic compartment prolapse. We describe our results with sacrocolpopexy with anterior and posterior polytetrafluoroethylene mesh (SCAPM) extensions. A prospective on-going study is presented of 12 consecutive, complicated patients referred to our tertiary referral unit with a median age of 60 years (range 39-69) who underwent SCAPM between April 1997 and June 1999. All patients had a history and physical examination, International Continence Society Prolapse Staging (ICS) and pre-operative multichannel urodynamics testing with their prolapse reduced. All patients had an ICS grade 2, triple compartment prolapse or worse for inclusion into this study. The operative results were assessed with a 10-point visual analogue scale (VAS) for personal satisfaction and the (non-validated) St George's Hospital symptom questionnaire assessing urgency, urge incontinence, stress incontinence, splinting, digitation, sexual activity and function. All patients were reviewed during February 2002 by an independent observer (B.G. gynaecologist) no longer associated with the Department of Urogynaecology. All patients were followed post-operatively for a median of 39 months (range 32-58). One patient had a recurrent grade 1 cystocele and another a grade 1 rectocele. The median VAS score for personal satisfaction with the operative results was 8 (range 6-10). There was one patient with de novo urgency and one with de novo stress incontinence. Four of the five patients who needed to splint or digitate to empty the rectum no longer required these measures post-operatively. There were no reports of de novo dyspareunia, and two patients had improved vaginal lubrication. Two patients, each with more than five prior vaginal procedures, had a total of three episodes of mesh erosion through the posterior vaginal wall. The SCAPM is an effective treatment for triple compartment prolapse and incomplete rectal emptying. Patient satisfaction is good.

Cosmetic results of early breast carcinoma treated with wide local excision, external beam radiotherapy and iridium-192 boost.

Cosmetic results of 80 patients with axillary lymph node negative or unknown T1 and T2 carcinoma of the breast who were treated with wide local excision, external beam radiotherapy and iridium-192 boost, were evaluated by the patient and the radiotherapist at 18-36 months. Their overall cosmetic results were assessed as good, very good or excellent by 80% of the patients. The radiotherapist's assessment was similar but in general the patients score was more favourable. After a follow-up of 24-72 months recurrence was found in only one patient at 40 months. This approach offers good cosmesis with low local recurrence rates in early breast carcinoma patients with negative axillary lymph nodes.

Neuropsychological correlates of subclinical paroxysmal EEG activity in children with epilepsy. 2: Quantitative aspects.

Altered cognitive functioning has often been reported in patients with epilepsy. In our study we looked for quantitative correlation between the recurrence of Subclinical Spike-and-Wave Discharges (SSWD) during EEG recording, the scores on the intelligence test (WISC) and the electro-clinical characteristics of 29 epileptic children with subclinical discharges of generalized spike-and-wave complexes. In our sample we found a below-normal mean IQ, with greater impairment on performance than on verbal tasks. No clear quantitative correlation was found between the weighted scores on the various subtests and the "time density" of the spike-and-wave complexes. These findings suggest that the SSWD interfere with cognitive development (mainly with visuo-spatial and sensorimotor coordination abilities) and selectively impair some of the functions involved in the cognitive processes.

Preparation for marrow transplantation in Hodgkin's and non-Hodgkin's lymphoma using Bu/CY.

The results of autologous and allogeneic BMT in 44 patients with Hodgkin's or non-Hodgkin's lymphomas who received preparative therapy consisting of busulfan 16 mg/kg and cyclophosphamide 120 mg/kg are presented. Sixteen patients are surviving free of disease between 8 months and 6 years after transplantation. Thirteen patients either did not attain complete remission or experienced a recurrence of their disease. Fifteen patients died from treatment-related complications. Karnofsky score < or = 70, lactate dehydrogenase greater than twice normal and the development of hepatic veno-occlusive disease were associated with failure to achieve lymphoma-free survival.

[Two stages reimplantation for infection after knee arthroplasty. Apropos of a series of 29 cases].

PURPOSE OF THE STUDY: The purpose of this work was to precise diagnosis and treatment of infected total knee arthroplasty with two stage reimplantation. MATERIAL: 29 infected total knee arthroplasties were operated between 1984 and 1994 and included in this study (mean F.U. 3.5 Y). There were 20 females and 9 males, mean age 70 (46-83). The original arthroplasty was done for OA in 28 patients, RA in one. The arthroplasties were: UHK 2, Bicompartmental 2, Tricompartmental 19. 20 TKA were cementless. 14 patients showed one or several risk factors. Infection was diagnosed in 1 of 2 ways: preoperative aspiration or culture of surgical specimen. There were 12 staphylococcus epidermidis, 8 staphylococcus aureus, streptococcus (n = 2) acinetobacter (n = 2), peptococcus (n = 1) pseudomonas (n = 1), gemella morbidellum (n = 1). 6 were non identified. METHOD: The protocol for two stage reimplantation began with components and cement removal. A synovectomy was performed. The knee cavity was filled with antibiotic cement spacer and the wound was closed. The leg was placed in a splint. All patients underwend a continued antibiotic therapy, specific in 20 cases with isolated organisms. A total knee arthroplasty was performed, using a total posterior cruciate substituting prosthesis, 6 to 8 weeks after components removal (2-24). All patients received parenteral antibiotics after reimplantation for not less than 2 months (2-6). RESULTS: Infection was eradicated in 24 cases, 22 in one time, 2 bad second debridement. At last follow-up the average Hungerford score was 75.6/100, the average Knee society knee score was 80 and the average functional score was 70. Mean range of flexion was 95 degrees. 6 patients had recurrent infection and poor result. They underwent arthrodesis. 5 of the 6 patients had solid mature fusion at last follow-up. DISCUSSION: The results of two stage reimplantation for infected total knee replacement showed that this is the method of choice for infection treatment and acceptable function restoration. As other authors, we get a good success rate (82 per cent). Functional result was better with identified microorganisms, but we did not find any correlation with organisms type or infection length. Punction and bone scanning are of great help for diagnosis in difficult chronical cases. Organism identification is fundamental for infection duration. Staphylococcus epidermidis was the most frequent identified organism. New procedures using articulated cement spacer may improve functional results.

Multiinstitutional validation of the UCSF cancer of the prostate risk assessment for prediction of recurrence after radical prostatectomy.

BACKGROUND: The University of California, San Francisco (UCSF) Cancer of the Prostate Risk Assessment (CAPRA) is a novel preoperative index which predicts the risk of biochemical recurrence after radical prostatectomy. The performance of the index is at least as good as the best available instruments based on clinical variables, and the 0 to 10 score is simple to calculate for both clinical and research purposes. This study used a large external dataset to validate CAPRA. METHODS: Data were abstracted from the Shared Equal Access Regional Cancer Hospital (SEARCH) database, a registry of men who underwent radical prostatectomy at 4 Veterans Affairs and 1 active military medical center. Of 2096 men in the database, 1346 (64%) had full data available to calculate the CAPRA score. Performance of the CAPRA score was assessed with proportional hazards regression, survival analysis, and the concordance (c) index. RESULTS: Of the studied patients, 41% were non-Caucasian, and their mean age was 62 years. Twenty-six percent suffered recurrence; median follow-up among patients who did not recur was 34 months. The hazard ratio (HR) for each 1-point increase in CAPRA was 1.39 (95% CI [confidence interval], 1.31-1.46). The 5-year recurrence-free survival rate ranged from 86% for CAPRA 0-1 patients to 21% for CAPRA 7-10 patients. Increasing CAPRA scores were significantly associated with increasing risk of adverse pathologic outcomes. The c-index for CAPRA for the validation set was 0.68, compared with 0.66 for the original development set. CONCLUSIONS: The UCSF-CAPRA accurately predicted both biochemical and pathologic outcomes after radical prostatectomy among a large, diverse, cohort of men. These results validated the effectiveness of this powerful and straightforward instrument.

Psychosocial concerns of Nigerian women with breast and cervical cancer.

Cancer has the potential to provoke worries which should be assessed in order to adequately respond to patients' problems. We highlight in this paper the problems that concerned 30 women with cervical cancer (mean age 51.2) and 76 with breast cancer (mean age 44.9), how these concerns affected their emotional lives, and the factors associated with these worries. They were interviewed with the 33-item modified version of a German questionnaire rating psychosocial concerns (FBS) by Sullwold, and Goldberg's General Health Questionnaire (GHQ-12) for psychopathological symptoms. Cervical cancer patients had significantly higher FBS and GHQ-12 scores than breast cancer. Breast cancer cases had FBS scores similar to those of women with sickle cell disease and insulin-dependent diabetes mellitus. The commonest recurrent worries in both groups were depression about their condition (45%), thoughts of death (37%), insomnia (33.3%), bodily odour (30%), impairment of work efficiency (30%) terrifying dreams (27%) and fear of illness being life-long (25%). Over 90% denied experience of worries indicating social stigma. FBS scores were significantly correlated with GHQ scores and both were negatively associated with adequacy of social contacts. These data suggest the need for psychosocial intervention in such cases in Nigeria.

High-dose-rate brachytherapy in the treatment of recurrent and residual head and neck cancer.

OBJECTIVES/HYPOTHESIS: Interstitial and endocavitary brachytherapy are well-accepted kinds of radiotherapy that are commonly used in recurrent head and neck cancer. Most reports about brachytherapy in the successful treatment of head and neck tumors used low-dose-rate brachytherapy. There are only a few reports about high-dose-rate brachytherapy (HDRBT) in head and neck cancer patients. METHODS: After 10 years of experience with HDRBT with Ir 192, we have analyzed the results regarding response rates, survival time, and side effects. Between 1991 and 2000, 90 consecutive patients (68 men, 22 women) were treated with interstitial (68 patients) or intracavitary (22 patients) HDRBT in the head and neck area. Primary tumor locations were as follows: oropharynx (n = 26), tongue/floor of mouth (n = 22), nasopharynx (n = 10), nose/paranasal sinuses (n = 9), salivary glands (n = 5), hypopharynx (n = 5), CUP syndrome (n = 5), and others (n = 8). High-dose-rate brachytherapy was administered in 51 patients with recurrent disease and in 32 patients with residual tumor after primary radiochemotherapy. Seven patients were given exclusive HDRBT in a primary palliative situation. The single dose per fraction ranged from 1.5 to 7.5 Gy (median value, 5 Gy), and the total HDRBT dose ranged from 4.0 to 42.0 Gy (median value, 17.5 Gy). RESULTS: The overall remission rate was 81% with a 46% rate of complete remissions. We observed no change in or progression of tumor in 17 cases (19%). The rate of complete remissions (and median overall survival time) was different in the three therapy groups: in case of recurrent disease, 28% (6 mo); in case of residual tumor, 84% (25 mo); and in primary palliative brachytherapy, 0% (1 mo). Late toxicities III and IV (radiation treatment oncology group score) occurred in 6 of 90 (6.7%) patients. CONCLUSIONS: High-dose-rate brachytherapy proved to be an effective treatment modality in locoregional recurrent head and neck cancer. In cases with persistent or residual tumor after primary radiochemotherapy a local boost with brachytherapy can improve the chance of cure of tumor disease.

Prognostic relevance of Tiam1 protein expression in prostate carcinomas.

The Rac-specific guanine nucleotide exchange factor, Tiam1, plays a major role in oncogenicity, tumour invasion and metastasis but its usefulness as a prognostic marker in human cancer has not been tested yet. In the present study, Tiam1 expression was analysed in benign secretory epithelium, pre-neoplastic high-grade prostatic intraepithelium neoplasia (HG-PIN) and prostate carcinomas of 60 R0-resected radical prostatectomy specimens by semiquantitative immunohistochemistry. Tiam1 proved significantly overexpressed in both HG-PIN (P<0.001) and prostate carcinomas (P<0.001) when compared to benign secretory epithelium. Strong Tiam1 overexpression (i.e. > or =3.5-fold) in prostate carcinomas relative to the respective benign prostatic epithelium was statistically significantly associated with disease recurrence (P=0.016), the presence of lymph vessel invasion (P=0.031) and high Gleason scores (GS) (i.e. > or =7) (P=0.044). Univariate analysis showed a statistically significant association of strong Tiam1 overexpression with decreased disease-free survival (DFS) (P=0.03). This prognostic effect of strong Tiam1 overexpression remained significant in multivariate analysis including preoperative prostate-specific antigen levels, pT stage, and GS (relative risk= 3.75, 95% confidence interval=1.06-13.16; P=0.04). Together, our data suggest that strong Tiam1 overexpression relative to the corresponding benign epithelial cells is a new and independent predictor of decreased DFS for patients with prostate cancer.

Psychological and immunological predictors of genital herpes recurrence.

The relationships among stressful life experience, mood, helper-inducer (CD4+) and suppressor-cytotoxic (CD8+) T cells and genital herpes simplex virus (HSV) recurrence were investigated prospectively in 36 patients with recurrent HSV. The following factors were measured monthly for six months: stressful life experience (including current acute and ongoing stressors, residual effects of previous stressors, and anticipation of future stressors), negative mood, health behaviors, other possible HSV triggers, HSV recurrences, and the proportion of CD4+ and CD8+ cells (in half the sample). Results averaging monthly scores over the six-month study period indicated that: 1) subjects with high levels of stressful experience had a lower proportion of both CD4+ and CD8+ cells, 2) subjects with high levels of depressive mood, anxiety, or hostility had a lower proportion of CD8+ cells, and 3) subjects with high levels of depressive mood who did not report many symptoms of other infections had a higher rate of HSV recurrence. A model is proposed linking depressive mood, CD8+ cells, and HSV recurrence.

Permanent low-activity iodine-125 implants for cerebral metastases.

Beginning in 1987, selected patients with metastatic brain tumors were treated with permanent implants of low-activity radioactive iodine-125(125I) seeds. These patients underwent craniotomy, gross total resection of the metastatic lesion, and placement of the seeds. In general, criteria for treatment included the presence of a recurrent tumor with a volume too large to permit radiosurgery, and a Karnofsky Performance Score of 70 or higher. Thirteen patients underwent 14 implant procedures; all received external whole-brain radiotherapy. Implant dose ranged from 43 Gy to 132 Gy, with a mean of 83 Gy. Survival after implantation ranged from 2 weeks to almost 9 years, with a median of 9 months. Clinical and radiographic local control was obtained in 9 patients. Two patients died of acute, postoperative complications within a month of implantation, so no information regarding tumor control is available for them. Late complications included a bone flap infection in one patient and a CSF leak in another; both were treated without further sequelae. These results demonstrate that permanent 125I implants can results in good survival and quality of life, and occasionally can yield long-term survival. Potentially, it is a cost-effective treatment in that a separate procedure for stereotactic implantation or radiosurgery is not needed, as is the case with the use of temporary high-activity seeds. The permanent implantation itself adds less than 10 minutes to the craniotomy, and the risk of symptomatic radiation necrosis is low. We recommend consideration of this procedure in patients harboring large, recurrent metastatic tumors that require further surgery.

[Predictive value of a tumor marker combination for the monitoring of ovarian cancer].

The tumour markers carcinoembryonic antigen (CEA), ferritin, cancer antigen 125 (CA 125) and tissue polypeptide antigen (TPA) were measured by radioimmunoassay in sera from 80 patients with ovarian cancer pre-operatively, postoperatively, during cytostatic chemotherapy and on follow up. Discriminant analysis was applied to obtain retrospective classification of 60 patients into a group showing a favourable course of the disease (no recurrence, tumour regression) and into a group with an unfavourable course (recurrence, progression of the tumour). The classification was based on the introduction of the Cutting Score. By means of this bio-mathematical model it was possible to make at least a short-term prognostic statement in a further 20 patients. It is suggested that invasive diagnostic procedures may not be required in patients who are found to have normal tumour marker levels.
