ABSTRACT

Diabetic ketoacidosis (DKA) is a common medical emergency situation. In rare cases, glycemic changes associated with the menstrual cycle may create a predisposing factor for DKA. In the absence of facilitating factors that may cause DKA, catamenial DKA should be considered. In the patients with catamenial DKA, increasing the insulin dose 1-2 days before menstruation may prevent the development of hyperglycemia or DKA associated with menstrual cycle. In this study, we present a 21-year-old female with type 1 diabetes mellitus (DM) that recurrently applied to our hospital due to DKA a few days prior to menstrual bleeding.

ABSTRACT

PURPOSE: The gene expression of 3 oral squamous cell carcinoma (OSCC) human cell lines, BHY, HN, and HSC-3, were studied based on their reported ability to invade adjacent bone or metastasize to cervical lymph nodes and/or distant organs. MATERIALS AND METHODS: The characteristics of each cell line were confirmed on scid mice using micro-positron emission tomography (PET)/computerized tomography (CT) imaging techniques. Complimentary DNA (cDNA) microarray techniques were used to determine the gene expression profile differences between each of the three OSCC cell lines. RESULTS: BHY, HN, and HSC-3 cell lines expressed 139, 214, and 128 up-regulated genes; and 117, 262, and 117 down-regulated genes, respectively. The clusterization of data showed that there are 13 genes that are up-regulated and 83 genes that are down-regulated in all 3 OSCC cell lines. Collection of genes organized by pathway may cause aggregate evaluation of anomalies. Thus the pathway analysis performed for each cell line based on cDNA microarray results showed BHY, HN, and HSC-3 cell lines to have 8, 10, and 3 up-regulated pathways and 3, 9, and 6 down-regulated pathways, respectively. CONCLUSIONS: This study showed that cDNA microarray analysis is an effective tool for mapping molecular signatures. With this technique it is possible to observe the entire genome of a malignant tumor so as to appreciate the simultaneous interactions among thousands of genes.

ABSTRACT

BACKGROUND: Turkey is an endemic area for thyroid diseases. The Aegean region is well documented for increased prevalence of thyroid disorders. In this study we investigated the demographic and clinical features of subacute thyroiditis (SAT) patients who had been diagnosed and treated in Ege University. METHODS: The hospital files of patients admitted to the endocrinology clinic of Ege University between January 1987 and December 2001 were retrospectively evaluated. Patients who had been diagnosed as having any thyroid disorder were determined. RESULTS: 176 fulfilled diagnostic criteria for SAT. The majority of patients with SAT were diagnosed as having subacute granulomatous thyroiditis (169/176) (134 females, 35 males, mean age 34.0+/-17.8 yr); 69% of the patients were between 30-50 yr of age. Thyroid pain was present in 97.1% of female patients, and in 100% of male patients. High fever was evident in 78 patients (46.2%). Mean erythrocyte sedimentation rate (ESR) was 43.42+/-39.68 mm/h. Anti-thyroglobulin antibody was positive in 20%, and anti-thyroid peroxydase antibody was positive in 4% of patients. Among patients who were treated with non-steroidal anti-inflammatory drugs (NSAD) 10 female patients (10.6%), and 3 male patients (12%) developed recurrence of the disease. Among patients who were treated with prednisolone 7 female patients (17.5%), and one male patient (10%) developed recurrence. There was no significant difference regarding the recurrence rates between patients who were treated with NSAD and patients who were treated with prednisolone. CONCLUSION: With the exception of ESR, demographic, clinical, laboratory, and imaging findings and prognoses of our patients were comparable to the previous reports.

ABSTRACT

PURPOSE: Proteolytic enzymes may confer specific types of invasion and metastasis in patients with oral squamous cell carcinoma (OSCC). The purpose of this study was to determine if OSCC that invades adjacent bone has different proteolytic enzyme expression profiles than OSCC that metastasizes to lymph nodes or distant organs. Three OSCC cell lines, BHY, HSC-3, and HN, with known behavior regarding bone invasion and lymph node and distant metastatic profiles, were evaluated. The characteristics of a control, human normal nasal epithelial cell line (HNEC), and BHY, HSC-3 and HN were evaluated with regard to their expression of the matrix metalloproteinases and cathepsins. MATERIALS AND METHODS: Expressions of proteolytic enzymes including matrix metalloproteinase, MMP-1, MMP-2, MMP-3, MMP-9, extracellular matrix metalloproteinase inducer (EMMPRIN), cathepsin B, and cathepsin L were compared using immunocytochemistry and flow cytometry in 3 OSCC cell lines and HNEC. The cell morphologies of these 4 cell lines were compared using transmission electron microscopy (TEM). RESULTS: All OSCC cell lines showed higher expression of all the proteolytic proteins when compared with HNEC, except the HSC-3 cell line showed no difference in the expression of MMP-9. There was no detectable difference at the expression level of MMP-1, MMP-2, MMP-3, cathepsin B, and cathepsin L in any of the OSCC cell lines. However, MMP-9 and EMMPRIN levels were higher in the BHY cell line. According to electron microscopy, the cells of the HSC-3 cell line were the smallest and least differentiated among the 3 OSCC cell lines. The BHY cell line was the most highly differentiated showing interdigitation and numerous cell junctions. CONCLUSIONS: MMPs play an important role in the invasion and metastasis of oral cancer. MMP-9 might play a more important role than MMP-2 during invasion. Increased expression of MMP-1, MMP-9, and EMMPRIN proteins might be involved in invasion of OSCC to adjacent bone, as they are necessary for the collagen matrix degradation. Increased expression of MMP-3, cathepsin B and L in OSCC might be associated with both invasion and a high incidence of metastasis.

ABSTRACT

BACKGROUND: The main metabolic pathway for defluorination of sevoflurane in the liver produces inorganic fluoride (Fl). The metabolism and effect of sevoflurane on the kidney is not clear during anhepatic phase in liver transplantation. The goal of the present study was to investigate the metabolism and renal effect of sevoflurane by measuring plasma and urine inorganic fluoride, urinary N-acetyl-glucosaminidase (NAG), and plasma creatinine levels in patients undergoing liver transplantations. METHODS: After institutional approval and informed consent, we studied nine cases of orthotopic liver transplantation after anesthesia was induced with 5 mg . kg(-1) thiopental, 1 mug . kg(-1) fentanyl intravenously, the trachea was intubated after vecuronium bromide 0.1 mg . kg(-1). Anesthesia was maintained with sevoflurane (2%), O(2), and N(2)O at a total gas flow of 6 L . min(-1) using a semiclosed circle system with a sodalime canister. Blood and urine samples were obtained to measure plasma and urine fluoride concentrations and urinary NAG excretions before induction (P0), hourly during resection (P1, P2, P3), every 15 minutes during anhepatic phase (A1, A2, A3), hourly after reperfusion (neohepatic phase) (N1, N2, N3), and postoperative first hour (Po1). Preoperative (T0) and postoperative day 1 (T1), 3 (T3), 7 (T7) plasma blood urea nitrogen (BUN) and creatinine (Cr) levels were also recorded. RESULTS: Mean duration of surgery was 9:06 +/- 0:09 hours. Mean inorganic fluoride concentrations in plasma were in the range of 0.71 +/- 0.30 to 28.73 +/- 3.31 mumole . L(-1). In P3, N1, N2, N3, increases in plasma inorganic fluoride concentrations were significant (P < .05) and reached a peak value at Po1. The mean urine inorganic fluoride concentrations were 12.49 +/- 2.04 to 256.7 +/- 49.62 mumole . L(-1). In A2, A3, N1, N2, and N3, mean urine inorganic fluoride concentrations were significantly increased (P < .05) and the peak value was observed at Po1. Mean NAG concentrations in urine varied (5.6 +/- 1.6 IU . L(-1) to 12.5 +/- 1.14 IU . L(-1)) and peak level was observed at 30 minutes of the anhepatic phase (A2), which did not exceed the normal values for urine NAG levels (1.5 to 6.1 U . L(-1)). No impairment was observed in serum BUN and creatinine levels at any time. While there was only a slight increase in NAG during anhepatic phase, there was no change in plasma F1. CONCLUSIONS: Sevoflurane seemed to have minimal effect on kidney functions of BUN and Cr levels during liver transplantation. Although urine F1 and NAG levels increased during the anhepatic phase plasma F1, BUN, and Cr levels did not, suggesting that renal F1 production may occur in the absence of hepatic function. The renal effect of sevoflurane in chronic liver disease is controversial and must be investigated in further studies.

ABSTRACT

We report newly presenting systemic and local allergic reactions to egg in a 55-year-old woman. The patient did not have a history of egg allergy in childhood or occupational exposure to egg proteins; nor did she report any disease that is known to be related to food allergy. A skin prick test with commercial extracts, prick-to-prick test, CAP radioallergosorbent assay, and a double-blind, placebo-controlled food challenge test were used to prove egg allergy. Because egg allergy mainly affects children and symptoms frequently disappear with age, the late onset in this patient is rare.

ABSTRACT

In a case of liver transplantation, sevoflurane metabolism was studied to investigate if sevoflurane has an extrahepatic metabolism or possible nephrotoxicity in the presence of chronic liver disease. Plasma blood urea nitrogen (BUN) and creatinine and urine levels of N-acetyl glycosaminidase (NAG) and beta2 microglobulin were assessed intraoperatively and for 11 days postoperatively. We observed a close relation between urine NAG excretion and urine inorganic fluoride levels in the intraoperative period and early postoperative days. The NAG levels were greater than normal despite the peak serum inorganic fluoride concentration of 18.94 micromol/L. No impairment was observed in serum BUN or creatinine levels in these periods.

ABSTRACT

OBJECTIVES: Clinical and experimental trials have demonstrated that some of selective serotonin reuptake inhibitors (SSRIs) have some suspicious effects on blood glucose levels in different directions. Especially fluoxetine and sertraline are studied in this point of view. These drugs are also used in treatment of depression and peripheral neuropathy in diabetic patients. Paroxetine and fluoxetine, members of this drug group, besides having antidepressant effects were shown to have antinociceptive effects in animals and humans. They can be used in the treatment of chronic pain as an adjuvant drug or alone. But less is known about their actions on pain in case of diabetes. The aim of this study is to investigate the antinociceptive effects of fluoxetine and paroxetine in diabetic and non-diabetic mice while monitoring their effects on blood glucose levels. METHODS: Mice of either sex were randomly used in experiments. The antinociceptive effects of paroxetine and fluoxetine were evaluated using hot plate test both in diabetic and non-diabetic mice. The effects of these drugs on blood glucose levels were also evaluated in another group of mice both in diabetic and non-diabetic mice. RESULTS: Fluoxetine and paroxetine showed significant antinociceptive effect at all doses and at all times tested in non-diabetic mice, but they could not successfully show this effect in diabetic mice. They also had controversial effects on blood glucose levels. CONCLUSION: Although they showed increasing or decreasing effects on blood glucose levels in non-diabetic and diabetic mice, they showed antinociception on hot-plate test showing dissociation between blood glucose levels and analgesia.

ABSTRACT

PURPOSE: Many studies have reported both a gender difference in the rates of depression and its treatment by using any of the widely used antidepressant drug groups. Some studies suggest that females respond more poorly to tricyclic antidepressants than males and appear to respond better to selective serotonin reuptake inhibitors (SSRI). There is no study investigating the analgesic/antinociceptive effects of antidepressant drugs on the basis of gender difference. In this study, we aimed to investigate the antinociceptive effect of paroxetine on the basis of gender difference. METHODS: The antinociceptive effect of paroxetine was tested using hot plate test in Balb/c mice (30-40 g). The animals were divided into eight groups on the basis of gender. FINDINGS: While paroxetine did not induce an antinociceptive effect in both sex at a dose of 1 mg kg(-1), it showed significant antinociceptive effects in both sex at a dose of 5 or 10 mg kg(-1). None of the doses of paroxetine revealed a gender difference in its antinociceptive action. CONCLUSION: There are several studies showing positive or negative evidence on the gender difference of paroxetine's antidepressant effect, but in the literature there is no study about the gender difference of paroxetine's or any other SSRI drug's antinociceptive effect. In conclusion, our results do not show any gender difference in antinociceptive effect of paroxetine that may be important especially when it would be used as an adjuvant agent in some painful conditions.

ABSTRACT

Serotonin (5-HT) is known to be an important mediator in pain modulation. Some centrally acting agents, like selective serotonin reuptake inhibitors (SSRIs), modulate pain. Activation of the endogenous opioid mechanisms or potentiation of analgesic effect by serotonergic and/or noradrenergic pathways might be involved in antinociception of SSRIs. However, peripheral mechanisms of nociception are not clear. In this study, the antinociceptive effect of paroxetine, its interaction with the opioidergic system and serotonin receptors were tested using the writhing test in mice. Paroxetine (5, 10, 20 mg/kg) induced an antinociceptive effect following i.p. administration in writhing test. For the groups in which the antagonists were tested, the dose of paroxetine that caused a significant and equipotent analgesic effect similar to 0.5 mg/kg morphine was selected. Naloxone significantly antagonized the antinociceptive effects of both paroxetine and morphine in a similar pattern and magnitude. Ketanserin (5-HT(2)-receptor antagonist) or ondansetron (5-HT(3)-receptor antagonist) alone did not alter the nociceptive action of acetic acid. While the antinociceptive effect of paroxetine was highly potentiated by ketanserin, ondansetron reduced that antinociception. In conclusion, our results indicate that the antinociceptive effect of paroxetine mainly depends on central opioidergic and serotonergic mechanisms. Peripheral serotonergic mechanisms/receptors may contribute to this antinociceptive effect, especially by 5-HT(3)-receptor subtypes.

ABSTRACT

Antidepressant drugs, especially tricyclics have been widely used in the treatment of chronic pain, but not in acute pain. Because of numerous undesirable side effects, the selective serotonin reuptake inhibitors (SSRIs), with their favorable side effect profile, are preferred nowadays. An activation of the endogenous opioid mechanisms or potentiation of the analgesic effect mediated by serotonergic and/or noradrenergic pathways are thought to be involved in the antinociceptive action of SSRIs. In this study, the potential antinociceptive effect of paroxetine and its interaction with opioidergic system and serotonin receptors were evaluated. The antinociceptive effect of paroxetine was tested using a hot plate test in mice. Paroxetine, a SSRI antidepressant drug, induced an antinociceptive effect following i.p. administration. This antinociception was significantly inhibited by naloxone, an opioid receptor antagonist, suggesting the involvement of opioidergic mechanisms. While ondansetron (a 5-HT(3)-receptor antagonist) inhibited the effect of paroxetine, ketanserin (a 5-HT(2)-receptor antagonist) could not. In conclusion, paroxetine-induced antinociception, similar to morphine, suggests an involvement of direct or indirect action (via an increase in release of endogenous opioid peptide(s)) at opioid receptor sites and an involvement of serotonergic mechanisms mainly at the receptor level.

ABSTRACT

BACKGROUND: P-Selectin mediates adhesive interactions between platelets, leukocytes and endothelium to form thrombi. Our purpose was to investigate plasma soluble(s) P-selectin levels in patients with acute myocardial infarction (aMI) and the effect of thrombolysis on P-selectin levels. METHODS: Patients with aMI within the first 6 h of chest pain were enrolled prospectively. sP-selectin levels were determined by ELISA in the plasma of patients with aMI (n=32), stable angina (n=18), and healthy controls (n=15). Samples were obtained before, 3 and 24 h after reperfusion therapy with tissue plasminogen activator. Seven patients showed recurrent angina or failure to reperfuse. RESULTS: sP-selectin levels were significantly higher in aMI group than other groups (86.7+/-8.7 ng/ml, P<0.05). sP-selectin levels were similar in stable angina and control groups (28.8+/-4.4 vs. 25.4+/-7.3 ng/ml, P=NS). A significant increase in sP-selectin levels was observed 3 h after successful thrombolysis and this was followed by a decrease to near the baseline level late after reperfusion. But patients with failed reperfusion showed sustained high sP-selectin levels after 24 h of thrombolysis (P<0.05). CONCLUSION: The plasma sP-selectin level is elevated in aMI and it increases further following thrombolytic therapy. This increase is probably induced by activation of endothelial cells or platelets after myocardial ischemia and reperfusion during aMI. As the elevated levels are sustained in patients with failed reperfusion, serial P-selectin levels may be used as a non-invasive indicator of successful thrombolysis in aMI.

ABSTRACT

It has been well established that, anti-thyroglobulin antibodies (ATG) and anti-microsomal antibodies (AMC) may be present in various thyroid disorders and other systemic autoimmune diseases, including Sjögren's syndrome (SS). However, presence of circulating autoantibodies to thyroid hormones, i.e. both to triiodothyronine (T3) and tetraiodothyronine (T4), has not been studied extensively in SS. Autoantibodies to T3 and T4 are very important, because serum T3 and T4 levels may be detected spuriously higher or lower, due to the presence of these autoantibodies. Their presence should be suspected when measured serum thyroid hormone levels are not consistent with clinical status of the patient. SS is a slowly progressive, inflammatory autoimmune disease, affecting primarily the exocrine glands. Thyroid gland, being a target in some autoimmune diseases, is well known to be affected in SS as well. Keeping this possibility in mind, we investigated T3 autoantibody levels and thyroid gland involvement in patients with SS. Twenty-six SS patients (F/M:22/4) with a mean age of 46.6 years, were recruited in this study. Twelve of them were accepted as primary SS (pSS), while others had secondary SS (sSS) (7 with rheumatoid arthritis (RA), 3 with systemic lupus erythematosus (SLE), 3 with progressive systemic sclerosis (PSS) and 1 with sarcoidosis). Thyroid function tests, including T3, T4, fT3, fT4, TSH, ATG, AMC, T3 antibody measurements, thyroid scintigraphy, thyroid ultrasonography and TRH stimulation tests were performed in all patients. We compared our results with those of the twenty healthy normal controls. Serum ATG and/or AMC were detected in three patients with pSS (25%) and no patients with sSS. No significant difference could be shown in the other parameters, including T3 autoantibodies and thyroid function tests. TRH stimulation test was also normal, showing that the hypothalamus-hypophysis-thyroid axis was not affected in patients both with pSS and sSS. In conclusion, we found that T3 autoantibody levels in pSS, were not significantly higher than sSS and normal controls.

ABSTRACT

To estimate the quantitative relation between chronic co-exposure to airborne n-hexane, toluen, methyl ethyl ketone (MEK) and various markers of immune function such as proliferative response of peripheral blood lymphocytes and lymphocyte subpopulations, a group of workers employed in a shoe factory were examined and compared with the unexposed controls. A significant increase was observed in the proliferative response of the peripheral lymphocytes to 2.5 and 5 µg PHA in the exposed group compared with that of the control group. There was no significant change in the percentage of circulating CD3(+), CD4(+), CD8(+), CD19(+), CD16(+) lymphocytes even in those workers with 3.3-fold higher mean levels of urine 2,5-hexanedione (2,5-Hxdn) and approximately twofold higher mean levels of urine hippuric acid (HA) as compared to controls. No difference was also observed between the mean granulocyte, monocyte, lymphocyte percentages of the groups, but a significant increase was observed in mean serum C3 level of the workers. Our results suggest that while lymphocyte subpopulations and leucocyte percentages are not affected, the proliferative response of the peripheral lymphocytes is stimulated after chronic co-exposure to n-hexane, toluen and MEK at the defined levels.

ABSTRACT

As the first study of its kind in the Aegean region of Turkey, we examined the incidence of sensitivity to Parietaria pollen in patients with allergic rhinitis and/or asthma living in the Mediterranean climate of the Aegean coast. On the Mediterranean, there are characteristic climatic conditions (mild winters, dry summers, etc.) which facilitate the growth of a typical vegetation and the production of allergenic pollen, such as that from Parietaria. These pollen types differ greatly from those of central and northern Europe. We skin tested 132 patients with a clinical history of seasonal rhinitis and/or asthma symptoms. Each patient was skin tested with extracts of grass, weed, tree and cereal pollens, and serum samples were collected for specific IgE assays for Parietaria. Sixty-nine of the 132 patients (52%) showed skin reactivity to Parietaria; seven of these (10%) had monosensitization to Parietaria. Fifty-six out of 69 patients (81%) had specific IgE in their serum to Parietaria pollen. Based on skin test reactions, we concluded that Parietaria is important in terms of clinical symptoms and that it is the most common weed pollen in the Aegean region in Turkey.

ABSTRACT

We report a case of Hutchinson-Gilford progeria syndrome (HGPS). The patient showed the characteristics of scleredema at the age of 2.5 months but developed all the manifestations of HGPS gradually until 10 months old. The possibility of development of HGPS should by considered in any case of scleredema at birth or in early infancy.

ABSTRACT

Kawasaki syndrome, also known as mucocutaneous lymph node syndrome, is an acute vasculitis of infants and young children. We describe a four-year-old girl who presented with fever, a diffuse erythematous maculopapular rash, bilateral nonpurulent bulbar conjunctivitis, dry, red, fissured lips, a tongue with a strawberry "appearance", an erythematous pharynx, indurative erythema, and edema and desquamation of the face, hands and feet. She probably developed mitral valve prolapse during the course of the disease. The diagnosis of Kawasaki syndrome was arrived at by excluding other diseases and by the presence of all the clinical criteria for Kawasaki syndrome. Since this syndrome is rarely encountered in Turkey, this case is presented and the literature regarding the syndrome is reviewed.
