Elevated C-reactive protein associates with early-stage carotid atherosclerosis in young subjects with type 1 diabetes

WSTĘP. Celem badania była ocena wpływu procesu zapalnego o małym nasileniu na wczesną fazę rozwoju zaawansowanej miażdżycy tętnic szyjnych u młodych chorych na cukrzycę typu 1. MATERIAŁ I METODY. U 55 chorych na cukrzycę typu 1 (22 mężczyzn i 33 kobiety, w wieku 22,1 &plusmn; 3,6 lat (&plusmn; SD), z cukrzycą trwającą 14,2 &plusmn; 5,7 lat) oraz u 75 osób bez cukrzycy z tej samej grupy wiekowej (28 mężczyzn i 47 kobiet) wykonano pomiar średniej i maksymalnej grubości kompleksu błony wewnętrznej i środkowej (IMT, intima-media thickness) w tętnicy szyjnej przy użyciu ultrasonograficznej prezentacji B. Stężenie białka C-reaktywnego dużej czułości (hs-CRP, high-sensitive C-reactive protein) oznaczano za pomocą immunonefelometru z zastosowaniem lateksu. WYNIKI. U chorych na cukrzycę typu 1 stężenie hs-CRP (mediana 0,35, zakres 0,05&#8211;1,47 mg/l u chorych na cukrzycę; mediana 0,14, zakres 0,05&#8211;1,44 mg/l u osób bez cukrzycy; p = 0,001) oraz średnia i maksymalna IMT (średnia IMT 0,76 &plusmn; 0,09 vs. 0,72 &plusmn; 0,04 mm, p = 0,003; maksymalna IMT 0,84 &plusmn; 0,11 vs. 0,77 &plusmn; 0,06, p < 0,0001) były wyraźnie większe niż u osób bez cukrzycy. Stężenie hs-CRP wykazywało wyraźną zależność ze średnią i maksymalną IMT u chorych na cukrzycę typu 1 oraz z maksymalną IMT u osób bez cukrzycy. Analiza metodą regresji wielowymiarowej przeprowadzona łącznie dla grupy chorych na cukrzycę oraz osób bez cukrzycy wykazała, że stężenie hs-CRP niezależnie koreluje ze średnią oraz maksymalną IMT (odpowiednio: p = 0,002 i p = 0,023), jak również z rozkurczowym ciśnieniem tętniczym, płcią i czasem trwania cukrzycy. WNIOSKI. Dane uzyskane w badaniu wskazują, że u młodych chorych na cukrzycę typu 1 stężenie hs- -CRP jest podwyższone, co może mieć związek z wczesną fazą rozwoju zaawansowanej miażdżycy tętnic szyjnych.INTRODUCTION. To evaluate whether low-grade inflammation contributes to early-stage advanced carotid atherosclerosis in young subjects with type 1 diabetes. MATERIAL AND METHODS. The mean and maximum (max) intima-media thicknesses (IMT) of the carotid artery were assessed using ultrasound B-mode imaging in 55 patients with type 1 diabetes (22 men and 33 women, aged 22.1 &#177; 3.6 years (&#177; SD), duration of diabetes 14.2 &#177; 5.7 years) and 75 age-matched healthy nondiabetic subjects (28 men and 47 women). High-sensitive C-reactive protein (hs-CRP) levels were measured with a latex-enhanced immunonephelometer. RESULTS. The patients with type 1 diabetes had significantly higher hs-CRP levels (median 0.35, range 0.05&#8211;1.47 mg/l vs. median 0.14, range 0.05&#8211;1.44 mg/l; P = 0.001) as well as significantly higher mean IMT and max IMT than the nondiabetic subjects (mean IMT 0.76 &#177; 0.09 vs. 0.72 &#177; 0.04 mm, P = 0.003; max IMT 0.84 &#177; 0.11 vs. 0.77 &#177; 0.06 mm, P < 0.0001). Hs-CRP levels were significantly correlated with the mean and max IMT of patients with type 1 diabetes and with the max IMT of nondiabetic patients. Multivariate regression analyses for both diabetic and nondiabetic subjects as a single group showed that hs-CRP levels are independently correlated with the mean IMT and max IMT levels (P = 0.002 and P = = 0.023, respectively) as well as with diastolic blood pressure, sex, and duration of diabetes. CONCLUSIONS. Our data indicate that hs-CRP levels are elevated in young patients with type 1 diabetes, possibly corresponding with early-stage advanced carotid atherosclerosis

Hyperthermotherapy for postoperative local recurrences of rectal cancer.

Between November 1984 and August 1992 we used hyperthermotherapy in six cases of local recurrence of rectal cancer. Hyperthermotherapy was performed on the average 8.7 times (range: 3-18) for each patient for 60 min each. All patients underwent combined radiotherapy and received a mean radiation dose of 42.5 Gy (range: 9-60 Gy). Five patients underwent heating within 1 h after irradiation and one patient simultaneously with the irradiation. Four patients underwent combined chemotherapy and two patients immunotherapy. Before the treatment all patients had painful lesions, but pain decreased posttherapeutically in five patients. Performance status improved in two patients. High carcinoembryonic antigen levels prior to the therapy in four patients decreased in all cases after treatment. Posttherapeutical computed tomograms revealed only minor response or no changes. After the treatment, four patients died of exacerbations of recurrent tumors and one patient of distant metastases. The patient who underwent simultaneous radiohyperthermotherapy is presently alive, in August 1992, 38 months after initiation of the treatment. The 50% survival time after initiation of the treatment was 25 months (range: 10-38 months). Hyperthermotherapy combined with radiotherapy, chemotherapy and/or immunotherapy was useful for the alleviation of pain in patients who developed local recurrence after surgery, and improved survival after recurrences can be expected.</p

Sodium temperature lidar based on injection seeded Nd:YAG pulse lasers using a sum-frequency generation technique

We report on a sodium (Na) temperature lidar based on two injection seeded Nd:YAG pulse lasers using single-pass sum-frequency generation. The laser power at 589 nm is 400 mW (40 mJ per pulse at a repetition rate of 10 Hz) and the pulse width is 22 nsec FWHM. The narrowband laser tuned to the Doppler broadened Na D(2) spectrum enables us to measure the temperature of the mesopause region (80-115 km). This solid-state transportable system demonstrated high performance and capability at Syowa Station in Antarctica for 3 years and at Uji in Japan for an additional year without any major operational troubles.

Pancreatic Pseudocysts - Proposal for Diagnosis and Surgical Management -

To determine the clinical features and problems presented by a pancreatic pseudocyst, eighteen patients managed at our hospitals since 1980 were reviewed. Males predominated with a ratio of 16: 2, and the average age was 36.2 years. Pseudocyst was located in the pancreatic head in 6, in the body in 6, in the tail in 5 and multiple pseudocysts in one case. The cause of pancreatic pseudocyst was chronic pancreatitis in 9 (including 8 patients with histories of alcoholism), acute pancreatitis in 2 and trauma in 7 patients, respectively. Three patients were associated with pancreatic calculi. Rupture of pseudocyst occurred in one patient with multiple cysts. Autopsy showed acute pancreatic necrosis and penetration to the stomach and duodenum. The indications for surgery were principally cyst-related symptoms(infection, hemorrhage, enlargement and compression of adjacent organs) and differential diagnosis from malignancy. Most of the patients underwent internal drainage ; 9 cystojejunostomy, 2 cystogastrostomy). Three patients underwent cystojejunostomy with longitudinal pancreaticojejunostomy for chronic pancreatitis. Massive hemorrhage after cystogastrostomy occurred in one patient with infected pseudocysts, which required removal of the cysts. Postoperative outcome of the 17 surgical patients was excellent in 16 patients. Only one patient died of pancreatitis associated with alcohol abuse, resulting in a 5.9% mortality. This study suggests that adequate internal drainage by pancreaticojejunostomy to treat the underlying pancreatic disease is most important to obtain an excellent prognosis in patients with pseudocysts

Biliary Cystadenocarcinoma - Report of 2 Cases -

The clinical and pathologic features of two patients with biliary cystadenocarcinoma were presented and the previous literatures were reviewed. Case 1 : A 52-year-old man complained of heart burn and weight loss. Abdominal ultrasound and CT offered suspicions of biliary cystadenocarcinoma of the left hepatic lobe. Left hepatic lobectomy was performed, but the tumor invaded to adjacent viscera. The resected tumor (26×21×5.5 cm) was multilocular cystadenocarcinoma with mucin production. He survived for one year and 8 months after surgery. Case 2: A 60-year-old man suffering from sudden-onset frost and high fever underwent left lateral segmentectomy of the liver with a diagnosis of cystadenocarcinoma defined by biopsy specimen in previous operation. The tumor (6.0×4.5×3.5 cm) was multilocular cyst with mucin-producing papillary adenocarcinoma. He died of recurrent cancer 2 years and one month after surgery. The histogenesis of cystadenocarcinoma is still unclear because of its rare disease. The presence of benign epithelium in our cases may support their origin from cystadenoma

A case of impacted supernumerary teeth occurring in the bilateral mandibular premolar area

In this study, a 1₇–year–old patient, who had regularly visited us from childhood, complained of discomfort in the andibular molar area, and impacted supernumerary teeth was confirmed by radiography. Its position was closely investigated using 3–dimensional CT, excision was performed, and a favorable course has been achieved. Thus, the importance of screening using panoramic radiography was reconfirmed

Data Classification Component in a Deductive Database System and its Application to Protein Structural Analysis

this paper, we describe the statistical data classification component of PACADE. We implemented the component for cluster analysis and discrimination analysis. In addition, we enhanced the aggregation function in order to calculate the characteristic values which are useful for data classification. By using the cluster analysis function, the proteins are thereby classified into different types of structural characteristics. The results of these structural analysis experiments are also described in this paper. 1 Introduction There are many fields of database application. Among these, scientific database systems for genome analysis have become very important in recent years. There is an ever increasing need to construct a well designed database system for genome analysis, which has the ability to handle the following features. 1. It can search efficiently for a large amount of genomic data, which is stored in a number of different database sources. 2. It allows a flexible description of query. 3. It can store not only &quot;data&quot; but also &quot;knowledge.&quot; 4. It is tolerant to disjunctive and erroneous data. 5. It provides the ability of not only search, but also analysis. Concerning features 1, 2 and 3, a deductive database is a promising paradigm for genome analysis. Since it has a logical interface like Prolog, queries are described flexibly and recursive rules can be processe
