Upper extremity deep vein thrombosis associated with indwelling peripheral venous catheters in gynecology oncology patients

OBJECTIVE: The goal of this study was to review the clinical presentation, management, and outcome of upper extremity deep vein thrombosis (UEDVT) in women with gynecologic malignancies who had indwelling peripheral venous access catheters. METHODS: From a retrospective review of medical records, we identified 13 patients with various gynecologic malignancies who were diagnosed with UEDVT during their disease course. We obtained tumor data, detailed information regarding the indwelling catheters used, and the diagnosis and management of UEDVT. RESULTS: Two hundred sixty-four women with gynecologic malignancies underwent insertion of an indwelling peripheral catheter by interventional radiology over a 5-year period. A total of 325 catheters were placed in these patients. Thirteen patients developed UEDVTs, and all had a catheter in situ at the time of DVT diagnosis. Eleven of thirteen patients had Peripheral Access System (PAS) Ports and two had peripheral indwelling central catheters (PICCs). The mean age of the patients was 53 years (range, 32-70). At the time of UEDVT diagnosis patients had the following: progressive cancer (n = 8), stable disease (n = 1), no evaluable disease (n = 4), and actively receiving chemotherapy (n = 7). Clinical signs/symptoms at the time of diagnosis included: catheter occlusion (n = 2), arm swelling and pain (n = 10), and superior vena cava syndrome (n = 1). Diagnosis of thrombosis was confirmed using Doppler ultrasound (n = 4), venography (n = 5), and both modalities (n = 4). Management of UEDVT consisted of anticoagulation with warfarin (2-6 months) (n = 9), urokinase infusion (n = 2), intravenous antibiotics for 21 days and heparin for 10 days (n = 1), arm elevation only (n = 1), Lovenox for 60 days (n = 1), and no therapy (n = 1). There were no complications associated with anticoagulation. No patient had a pulmonary embolism. The incidence of UEDVT among our patients with indwelling venous catheters was 5.7%. CONCLUSION: Symptomatic UEDVT is an uncommon complication of indwelling peripheral venous catheters in women with gynecologic malignancies. The risk of pulmonary embolism is low in this patient population.     

Diffuse large B-cell lymphoma occurring in patients with lymphoplasmacytic lymphoma/Waldenström macroglobulinemia. Clinicopathologic features of 12 cases

Of 92 patients with lymphoplasmacytic lymphoma/Waldenstr?m macroglobulinemia (LPL/WM) treated at our institution, diffuse large B-cell lymphoma (DLBCL) also developed in 12 (13%). In 10 patients, DLBCL developed 12 to 128 months (median, 44 months) after the diagnosis of LPL/WM. Two patients had LPL/WM and DLBCL simultaneously. Clinicopathologic features at diagnosis of LPL/WM did not predict the risk of DLBCL. Onset of DLBCL was characterized by worsening constitutional symptoms, profound cytopenias, extramedullary disease, and organomegaly. Immunoglobulin light chain expression was identical in both LPL/WM and DLBCL. In situ hybridization for Epstein-Barr virus (EBV) in 8 cases of DLBCL was negative. Of 11 patients with clinical follow-up information available, 8 (73%) died within 10 months of diagnosis of DLBCL. DLBCL, most likely as a result of histologic transformation, occurs in a subset of patients with LPL/WM and is associated with aggressive clinical course and poor outcome. EBV is unlikely to be involved in transformation.     

Rickettsioses in Swedish travellers, 1997-2001

From laboratory records, information was collected on all 77 cases of rickettsioses diagnosed in Sweden during 1997-2001, 14 of which were diagnosed as belonging to the typhus group and 63 to the spotted fever group. Signs of hepatic involvement occurred more frequently in the typhus group. Denominators for the number of journeys to different parts of the world were retrieved from a commercial Swedish tourist database. The estimated risk of rickettsioses in destinations outside Europe varied from 1 case in 140,000 travellers to south-east Asia to 1 in 1600 travellers to southern Africa. The risk of infection in southern Africa increased over the 5 y period and is now 4-5 times higher than the risk of acquiring malaria in the same region. Rickettsiosis is an important differential diagnosis to consider in the febrile traveller, especially from South Africa. It should be remembered that the serological response may be considerably delayed and in patients with a negative first serology, serological testing should be repeated. Where there is a strong suspicion of rickettsiosis treatment may have to be started without a confirmed diagnosis.     

Qualitative evaluation of elderly home residents' fixed and removable prostheses in relation to the ADL index

Functional diversity and biopsychosocial state is a significant issue, which greatly influences elderly oral health and state of fixed and removable prostheses.Objectives. The goal of the investigation was to evaluate the quality of fixed and removable prostheses in a group of elderly home residents in relation to the ADL index.Methods. The group consisted of 175 institutionalised elderly, mean age 76.8 years. Special care need was assessed on ADL scale. To evaluate the quality and need for replacement of fixed and removable prostheses Karlsson's and modified Nevalainen et al. indices were used.Results. Spearman's correlation analysis showed significant correlation of ADL index scores and both Karlsson's index values (rho=-0.468, p<0.01) as well as for modified Nevalainen's indices (rho=-0.572, p<0.01). Lower ADL score was correlated with poorer oral hygiene and condition of fixed or removable dentures. It was determined that 87% of the examined patients were in objective need of fixed, removable or combined prosthodontic treatment.Conclusions. The study showed that lower ADL index scores of functionally dependent elderly patients correlate with poorer condition of fixed and removable prostheses and greater need of fixed, removable or combined prosthodontic treatment.     

Analysis of the trace element contents of inner nucleus and outer crust parts of urinary calculi

In this study, the lead, cadmium, nickel, and aluminum concentrations were analyzed in inner nucleus and outer crust parts of various kinds of urinary calculi, and the results obtained were statistically compared. Significant differences were found among the element concentrations in the different stone groups. In general, higher element concentrations were found in the nuclei as compared with the crust parts. In addition, some significant intra- and intercorrelations were established among the elements analyzed. The results suggest that some trace elements, including lead, cadmium, nickel, and aluminum, together with other factors may have as yet no clarified functions in the stone precipitation process in the urinary tract.     

Effects of nerve growth factor on the neurotization of denervated muscles

Studies on surgical repair techniques of the peripheral nerve are still trying to improve the outcome. There are many studies on the effects of various neurotrophic factors on the transected peripheral nerve. Muscular neurotization, which is the direct implantation of the nerve to the target denervated skeletal muscle, is one of the techniques used when the primary repair of the peripheral nerves is not possible. The effects of nerve growth factor (NGF), which is one of the primary neurotrophic factors, on the reinnervation of denervated muscles by neurotization is investigated in this experimental study. The denervated soleus muscle was neurotized via peroneal nerve implantation (group 1), and NGF was administered to the neurotized muscle (group 2). All animals were evaluated at weeks 8, 10, and 12 using electromyography. Muscle contractility, muscle weight, and histological morphometric tests were performed at week 12. The experimental groups were compared with each other and normal control values. Electromyographically, group 2 (direct nerve implantation + NGF) demonstrated better reinnervation in all evaluations. The study of muscle weight showed that the muscle mass was 75% of the normal soleus muscle in group 1 and was 85% of the normal side in group 2 at the end of week 12. In group 1, the twitch force was 56% of the normal soleus muscle and was 71% in group 2. Tetanic force was 53% of the normal soleus muscle in group 1 and 68% in group 2. Histological morphometric studies revealed that there was a decrease in the density of the motor end plates in group 1, but there was no statistically significant difference between the normal soleus muscles and the NGF applied to group 2. The positive effects of NGF on the neurotization of denervated muscles seen in this study suggest that it may be useful for treating some difficult reconstructions caused by denervation.     

Interhemispheric intracranial pressure gradients in massive cerebral infarction

We report continuous bilateral intracranial pressure (ICP) monitoring immediately after transtentorial herniation in a patient with massive cerebral infarction to: 1) determine presence and time course of compartmental ICP differences, and 2) to study effects of therapy on both hemispheres. A 55-year-old man admitted with watershed infarctions in the left anterior-middle-posterior cerebral arteries distribution. Initial investigations demonstrated highly narrowed left extracranial internal carotid artery. Eight days later he developed unexplained lethargy and anisocoria. Head computerized tomography (CT) showed massive left hemispheric infarction, edema, and midline shift. Bilateral subarachnoid bolts demonstrated equally elevated ICP in both hemispheres. Hyperventilation and osmotic therapy produced near-identical ICP reduction bilaterally with resolution of anisocoria. Later, plateau waves and autonomic instability developed. Shortly before loss of brainstem function, interhemispheric ICP gradients (left greater than right) of 30-40 mm Hg developed. Intracranial pressure did not equalize prior to brain death determination. Bilateral ICP monitoring did not reveal an interhemispheric ICP gradient soon after transtentorial herniation in massive MCA infarction. The presence of interhemispheric ICP gradients in massive stroke remains unproven and further clinical study is necessary.     

IgE antibody quantification and the probability of wheeze in preschool children

BACKGROUND: IgE-mediated sensitization is usually considered a dichotomous variable (either sensitized or not). Quantitative IgE antibody analysis may better predict the expression of wheeze. OBJECTIVE: Within the context of a population-based birth cohort, we investigated the association among wheeze, lung function, and specific IgE antibody levels. METHODS: Children (n = 521) were followed to age 5 years with repeated questionnaires, skin testing, and measurement of lung function (specific airway resistance) and specific serum IgE (ImmunoCAP). RESULTS: Using specific IgE as a continuous variable, the risk of current wheeze increased significantly with increasing IgE to mite, cat, and dog (P < .0001). When IgE levels to these 3 allergens were summed, the probability of current wheeze increased 1.33-fold (95% CI, 1.21-1.47; P < .0001) per logarithmic unit increase, corresponding to an odds ratio of 3.1 at 10 and 4.25 at 30 kU(A)/L (kilo units of Allergen per liter). Similarly, increasing sum of mite-specific, cat-specific, and dog-specific IgE was associated with reduced lung function (P = .004). Among sensitized children (n = 184), the sum of mite, cat, and dog IgE was the strongest associate of current wheeze (odds ratio, 1.28; 95% CI, 1.13-1.46; P < .001), corresponding to an odds ratio of 2.56 at 10 and 3.32 at 30 kU(A)/L. There was no association between current wheeze and the size of skin test wheal. Furthermore, the sum of IgE to mite, cat, and dog at age 3 years increased the risk of persistent wheeze by age 5 years (2.15-fold/logarithmic unit increase in the specific IgE). CONCLUSION: IgE-mediated sensitization is not an all or nothing phenomenon. The probability of wheeze and reduced lung function increases with increasing specific IgE antibody levels.     

Controlling indoor allergens.

OBJECTIVES: Reading of this article reinforces the reader's knowledge of the role of allergen exposure in relation to asthma and its severity, as well as the relevance of allergen avoidance in the treatment of asthma. DATA SOURCES: Initial literature search for existing evidence-based guidelines, reviews, and meta-analyses was carried out, and further literature searches were performed to review individual randomized controlled trials. Evidence level was graded according to the Scottish Intercollegiate Guidelines Network recommendations. RESULTS: There is good evidence for the link between mite and cockroach allergen exposure and sensitization, and between sensitization and asthma. For pet allergens, some studies found that exposure to pets in early life was associated with specific immunoglobulin E sensitization and allergic disease later in childhood, whereas others reported a protective effect. The effectiveness of allergen reduction in the treatment of asthma is suggested by studies in which the patients improve substantially when moved into the low-allergen environment of hospitals or high-altitude sanatoria. Because of limitations in the design of the most clinical of studies, we do not yet have a conclusive answer on the effectiveness of domestic aeroallergen avoidance. CONCLUSIONS: Minimizing the impact of identified environmental risk factors is an important first step to reduce the severity of asthma. Although environmental control is difficult, it should be an integral part of the overall management of sensitized patients. However, what is unclear is which patients would benefit and by how much, and whether the intervention is cost-effective. These questions will be answered satisfactorily only by large randomized trials.
