The Structure and Compression of Medical Compression Stockings

This paper lays out standards of compression stockings and their classification into classes. The analysis of knitted fabric structure parameters, elongation and compression of moderate- and high-compression stockings was conducted. Stocking compression on specific parts of the stocking leg was measured on three sizes of a wooden leg model. For moderate-compression stockings, compression above the ankle was 32 hPa. For high-compression stockings, compression above the ankle was 60 hPa. Both groups of the analyzed compression stockings were made on modern one-cylinder hosiery automats. The legs of the stockings were made in single inlaid jersey 1 + 1. Both yarns were elastane covered. The finer yarn formed loops and its knitting into a course was significantly larger than in the other yarn, which was much coarser and does not form loops but “lay the weft in a bent way”. The smallest elongation of knitted fabric was above the ankle, where the highest compression was achieved, while the largest elongation was under the crotch, where the stocking leg exerted the smallest compression on the surface. The leg of the compression stocking acted as a casing that imposed compression on the leg and often reinforced it to be able to sustain compression loads.     

Predicting carotid restenosis by comparison of plaque MCP-1 mRNA expression and serum levels

As cardiovascular pathology grows in numbers, research into the discovery of new chemokine biomarkers should not be neglected, as they seem to be paramount in atherosclerosis prevention and its early detection. Chemokines attract and activate leukocytes and are well recognized in the environment of inflammatory response. MCP-1 is a valuable chemokine whose potential to become a new crucial atherosclerosis marker is surely worth investigating. Since quantities of MCP-1 found in lesions are as low as immeasurable, we propose the use of an immunohistochemical method for the quantification of MCP-1 levels in atherosclerotic lesions. Additionally, serum levels of MCP-1 can be measured by commercially available immunoassays. Proposed MCP-1 concentration increase may explain the acceleration in lesion’s atherosclerosis progression as chemokine activation occurs once they bind to specific ligands. If proven, this hypothesis would indicate the need for further studies in order to objectively link the increased MCP-1 expression with carotid restenosis.     

Hypercoagulability in Cushing’s syndrome: the role of specific haemostatic and fibrinolytic markers

Objective Hypercoagulability is a commonly described complication in patients with Cushing’s syndrome. Recent clinical studies have indicated various abnormalities of coagulation and fibrinolysis parameters which may be related to that phenomenon. The aim of this study was to investigate the mechanisms underlying the hypercoagulable state in patients with Cushing’s syndrome. Research methods and procedures A wide range of serum markers involved in the processes of blood coagulation and fibrinolysis was measured in a group of 33 patients with Cushing’s syndrome and 31 healthy controls. No participant was taking medication which could influence the result or had known diseases, except hypertension and diabetes, which could affect blood coagulation or fibrinolysis parameters. Results Patients with Cushing’s syndrome had higher levels of clotting factors II (P = 0.003), V (P < 0.001), VIII (P < 0.001), IX (P < 0.001), XI (P < 0.001) and XII (P = 0.019), protein C (P < 0.001), protein S (P < 0.001), C1-inhibitor (P < 0.001) and plasminogen activator inhibitor-1 (PAI-1) (P = 0.004). The activity of fibrinolytic markers, plasminogen (P < 0.001), antithrombin (P < 0.001) and antithrombin antigen (P = 0.001) was also increased in the patient group. Conclusion The study has demonstrated hypercoagulability in patients with Cushing’s syndrome manifest as increased prothrombotic activity and compensatory activation of the fibrinolytic system. We propose the introduction of thromboprophylaxis in the preoperative and early postoperative periods, combined with a close follow-up in order to prevent possible thromboembolic events in patients with Cushing’s syndrome.     

Premetastatic milieu explained by TLR4 agonist-mediated homeostatic inflammation

Accumulating evidence suggests that Toll-like receptor 4 (TLR4), a sensor for danger signals, is expressed not only in immune cells, but also in resident epithelial cells, and appears to participate in tissue homeostasis. To explain the premetastatic microenvironment created by the newly discovered endogenous TLR4 ligands, I propose a hypothesis of homeostatic inflammation that includes the classical danger hypothesis.     

Epidural morphine and neostigmine for postoperative analgesia after orthopedic surgery

In this study, we examined the side effects and analgesia of the combination of epidural neostigmine and morphine in patients undergoing orthopedic surgery. Sixty patients undergoing knee surgery were divided into four groups. The intrathecal anesthetic was 15 mg of bupivacaine. The epidural test drug was diluted in saline to a final volume of 10 mL. The control group received saline as the epidural test drug. The morphine group received 0.6 mg of epidural morphine. The neostigmine group (NG) received 60 micro g of epidural neostigmine. The morphine/neostigmine group received 0.6 mg of epidural morphine combined with 60 micro g of epidural neostigmine. The groups were demographically the same and did not differ in intraoperative characteristics. The visual analog scale score at first rescue analgesic and the incidence of adverse effects were similar among groups (P > 0.05). One patient from the NG complained of intraoperative nausea, closely related to spinal hypotension. Postoperatively, two patients from the NG had vomited once. The time (min) to first rescue analgesic was longer in the morphine/neostigmine group ( approximately 11 h) compared with the other groups (P < 0.05). The analgesic consumption (number of analgesic administrations in 24 h) was larger in the control group compared with the other groups (P < 0.05). IMPLICATIONS: The combination of epidural morphine and epidural neostigmine resulted in postoperative analgesia (11 h) devoid of side effects, being an alternative analgesic technique in the population studied.     

Radiotherapy after transcatheter arterial chemoembolization for patients with hepatocellular carcinoma and portal vein tumor thrombus

Transcatheter arterial chemoembolization (TACE) is used in the treatment of hepatocellular carcinoma; however, it has limited effect on portal vein tumor thrombus (PVTT). The purpose of this study was to assess the feasibility and efficacy of radiotherapy targeting the PVTT after TACE for the tumor in the hepatic parenchyma. TACE was performed using epirubicin hydrochloride, iodized poppy seed oil, and gelatin sponge particles. Radiotherapy was performed targeting the PVTT to a total dose of 50 Gy in 25 fractions during 5 weeks. Twenty consecutive patients were treated with this combined treatment. Sixteen of 20 patients could complete the planned radiotherapy. Partial response was observed in 10, no change in 4, and progression in 6. The response rate was 50% (95% CI 28-72%). The 1-year overall survival rate was 25% (95% CI 6-44%), and the median survival time was 5.3 months. It was difficult to determine the late toxicities because of disease progression and additional TACE, and only one patient died without disease progression. Radiotherapy after TACE is feasible for patients with hepatocellular carcinoma and PVTT. The survival figure, however, is still dismal, and further investigation is needed to establish the best combination of treatment modalities.     

Brush cytology and its comparison with histopathological examination in cases of diseases of the nose

Nasal cytology is a simple, easy, bloodless and quite reliable investigation. Although its utility was recognized as early as 1927 by Eyerman, it has not yet gained much popularity. Here, an attempt is made to assess its efficacy for the diagnosis of various inflammatory, benign and malignant conditions in 151 cases of common rhinological problems in the M.Y. Group of Hospitals, Indore MP, India. This method can be used as an adjuvant to clinical diagnosis and histopathological diagnosis as an outpatient department (OPD) procedure with the help of a nasal endoscope, as it was found to be a simple, reliable and time-saving procedure for further management. It can also be used as a screening test for the detection of symptomless patients particularly in precancerous lesions.     

Benign fibrous histiocytoma of the kidney

Studies on inhibition of nucleic acid biosynthesis by isoniazid and its possible prevention

Effect of isoniazid on nucleic acid biosynthesis was studied in Swiss mice. It was observed that i.p. injection of isoniazid stimulated activities of nuclease. Isoniazid also inhibits RNA biosynthesis in lung and liver tissue of 3-weeks old mice but has no inhibitory effect on the same in 6 weeks old mice. It inhibits DNA biosynthesis in lung tissue of 3- and 6-week old mice. With the decrease in nucleic acid biosynthesis and increased activities of nucleases the nucleotide pool is increased. I.p. injection of ammonium chloride produces inhibition of nucleic acid biosynthesis to a similar extent. Administration of amino acids L-arginine or L-Na-glutamate or of vitamins pyridoxine or folic acid along with isoniazid prevents the inhibitory effect of isoniazid on nucleic acid biosynthesis.
