Two-level artificial disc placement for spondylotic cervical myelopathy.

This report describes a 49-year-old woman who presented with a myeloradiculopathy with two-level spinal cord compression. She underwent C5-6 and C6-7 anterior cervical decompressions and placement of two Bryan disc (Medtronic Sofamor-Danek. Memphis, TN) prostheses. Whilst single-level cervical arthroplasty using the Bryan disc prosthesis has been described before, this is the first two-level case reported in the literature and opens the way for the possible future management of multilevel cervical cord compression in a way that maintains cervical motion, avoids donor site bone graft problems, and may reduce the incidence of adjacent segment disease.     

Effective high-capacity gutless adenoviral vectors mediate transgene expression in human glioma cells.

Glioblastoma multiforme (GBM) is the most common subtype of primary malignant brain tumor. Although serotype 5 adenoviral vectors (Ads) have been used successfully in clinical trials for GBM, the capacity of Ads to infect human glioma cells and the expression of adenoviral receptors in GBM cells have been challenged. In this report, we studied the expression of three molecules that have been shown to mediate adenoviral entry into cells, i.e., coxsackie and adenovirus receptor (CAR), integrin alphavbeta3 (INT), and major histocompatibility complex class I (MHCI), in rodent glioma cell lines and low-passage primary cultures and cell lines from human GBM. We correlated levels of expression of CAR, INT, and MHCI with transduction efficiency elicited by several high-capacity helper-dependent adenoviral vectors (HC-Ads). Expression levels of adenoviral receptors were variable among the different GBM cells studied. HC-Ad-mediated therapeutic gene expression was efficient, ranging between 20 and 80% of the total target cells expressing the encoded transgenes. Our results show no correlation between the levels of CAR, INT, or MHCI molecules and the levels of transgene expression or the number of GBM cells transduced. We conclude that expression levels of adenoviral receptors do not predict their transduction efficiency or biological function.

Renal relapse in bilateral synchronous testicular lymphoma

Bilateral synchronous testicular lymphoma is an uncommon presentation of non-Hodgkin's lymphoma. A young man with non-Hodgkin's lymphoma of both testes synchronously is described here. He underwent bilateral orchiectomy, received chemotherapy, and was in complete remission when there was a relapse in the kidneys. Salvage chemotherapy was given. The patient developed progression of the residual lesion subsequently and was started on palliation with chlorambucil and prednisolone. He was alive at 34 months after diagnosis with disease.     

Relationship between low glomerular filtration rate, hypertension, and microalbuminuria in type 1 diabetes mellitus

AIM: To investigate the influence of low glomerular filtration rate, as well as of systolic and diastolic hypertension, on microalbuminuria in patients with type 1 diabetes mellitus. METHODS: Twenty seven patients with type 1 diabetes mellitus (18 males, 9 females) were studied. All of the patients were below 50 years of age. In 93% of the cases, the duration of diabetes was less than 15 years. GFR was determined, after intravenous injection in the lying position, by using a 99m-Tc-DTPA, while microalbuminuria was calculated for the 24-hour urine using the nephelometric immunoassay (30-300 mg/24 h). The patients were divided into 3 groups according to the value of GFR. The values ranged from 90 to 125 ml/min/1.73 m2 were considered normal (in 63% of the patients in group 1), those above that range were considered as hyperfiltration (in 22.2% of the patients in group 2), while those below that range were considered as hypofiltration (in 13.8% of the patient in group 3). RESULTS: Data analyzed with the one-way ANOVA, indicated a significant statistical difference between the 3 groups in the duration of diabetes (p < 0.05), micro-albuminuria (p < 0.01), systolic BP (p < 0.01), diastolic BP (p < 0.05), fructosamine (p = 0.50), urea (p < 0.05), creatinine (p = 0.05), and uric acid (p < 0.05). Microalbuminuria correlated with the age of patients (p <0.05) (Spearman's rho), diabetes mellitus duration (p < 0.01), systolic BP (p < 0.05), diastolic BP (p < 0.05), LDL-cholesterol (p < 0.05). There was no statistically significant correlation between GFR and the other parameters. Hypertension, microalbuminuria, and the duration of diabetes correlated positively with the reduction of GFR, revealing the most frequent reduction of GFR in the patients with more than 15-year duration of diabetes. CONCLUSIONS: Hypertension and low GFR were associated with microalbuminuria in type 1 diabetes, while the duration of diabetes was shown to be the independent risk factor for the development of microalbuminuria.     

Factors related to experiencing respiratory failure in cases of opiate overdose for which care was provided in an open setting. Barcelona, Spain

BACKGROUND: To determine the factors associated with respiratory arrest in opiate overdoses (coma, pupillary miosis, respiratory depression, and response to naloxone) among injecting drug users in the Can Tunis quarter of Barcelona. METHODS: We ran a transversal observational study where all overdoses assisted between March, 2001 and June, 2002. After overdose treatment, data were collected using a standard questionnaire, including: patients' sociodemographic data, opiate and other substances' use prior to overdose, clinical signs and symptoms presented, and medical intervention received, by way of a standardised questionnaire. Logistic regression was used as a tool for analysis. RESULTS: Of 222 opiate overdose cases, 60.8% showed respiratory arrest. Of all risk factors tested, only prior abstinence heroin abstinence for 2 weeks or longer days (OR=1.893; p=0.04), and no previous consumption of benzodiazepines (OR:0.462; p=0.017), proved to have a statistically significant association with suffering a respiratory arrest. Concomitant use of alcohol, cocaine or methadone appeared not associated with suffering respiratory arrest in opiate overdose. CONCLUSIONS: The main risk factor for respiratory arrest in opiate overdoses was a prior abstinence period of more than 2 weeks. Benzodiazepines use was associated with absence of respiratory arrest in overdose cases. Alcohol or methadone use, as well as the use of larger quantities of heroin, was not associated with suffering respiratory arrest in opiate overdoses. A study of other factors, not included in this study, and that could interfere with our results, should be considered for their possible relationship to benzodiazepine use as well as to absence of respiratory arrest in overdose cases.     

Late recurrence of childhood acute lymphoblastic leukemia

Late relapse of childhood lymphoblastic leukemia 10 years after the end of treatment is rare. A young woman whose acute lymphoblastic leukemia recurred 11 years after the end of treatment for acute lymphoblastic leukemia is described, and the literature on late relapse of childhood acute lymphoblastic leukemia is reviewed.
