Four analgesic techniques for shockwave lithotripsy: eutectic mixture local anesthetic is a good alternative

BACKGROUND AND PURPOSE: Various sedative and analgesic medication has been used for shockwave lithotripsy (SWL). The aim of this study was to evaluate the efficacy of different anesthesia modalities in these patients. PATIENTS AND METHODS: One hundred patients were randomly divided into four groups. The first (Group F) received fentanyl 1 microg/kg intravenously (IV), the second (Group D) received diclofenac sodium 1 mg/kg intramuscularly (IM), the third (Group T) received tramadol 1.5 mg/kg IM, and the fourth (Group E) was given 15 g of eutectic mixture local anesthetic (EMLA) cream containing lidocaine and prilocaine. After routine preoperative evaluation, all patients received midazolam 2 mg IV 5 minutes before lithotripsy for sedative premedication. In all groups, a supplemental 25-microg bolus of fentanyl was administered IV when patients complained of pain, moved, or grimaced in response to the shockwaves. Pain intensity was evaluated on a 0- to 100-mm visual analog scale (VAS). The level of sedation was determined using the Observer's Assessment of Alertness/Sedation (OAS/S). Side effects such as bradypnea, oxygen desaturation, bradycardia, pruritus, and nausea and vomiting were recorded. RESULTS: There were no statistically significant differences among the four groups with regard to VAS, OAS/S scores, or side effects. In Group F, the mean arterial pressure was decreased significantly at 10 and 20 minutes. The patients in this group also manifested a decrease of oxygen saturation at the first, tenth, and twentieth minutes and the end of SWL. CONCLUSION: Application of EMLA cream was as safe and effective as fentanyl, diclofenac, and tramadol, and reduction of the fentanyl dose during SWL was possible.     

Effects of trimetazidine on acetic acid-induced colitis in female Swiss rats

Induction of colitis by acetic acid (AA) in the rat is widely used experimental model of inflammatory bowel disease (IBD) and ulcerations. AA as an irritant induces colitis involving infiltration of colonic mucosa with neutrophils and increased production of inflammatory mediators, such as hydrogen peroxide (H2O2), nitric oxide (NO), myeloperoxidase activity (MPO), and tumor necrosis factor (TNF-alpha). Trimetazidine (TMZ), an antianginal compound, was administered to investigate if its cytoprotective features in cardiac tissue are also effective in AA colitis where ischemic injury contributes to colitis. Administration of TMZ intraperitoneally improved the macroscopic and microscopic score alterations produced by AA. AA administration significantly elevated colonic MPO activity; however, treatment with TMZ significantly lowered this enzyme activity compared to AA. AA administration significantly enhanced superoxide dismutase (SOD) activities, except for AA + TMZ given rectally. TMZ treatment significantly lowered nitrate levels, but AA increased these levels. AA administration markedly lowered TNF-alpha levels, but TMZ treatment elevated these levels to control. These findings indicate that overproduction of NO may be involved in the immunosuppression observed during acute AA-induced rat colitis. In conclusion, TMZ treatment was more effective via the intraperitoneal than rectal route, and may be beneficial in therapy of colitis.     

Testicular chondrosarcoma

A case of primary chondrosarcoma of the testis is reported. A 40-year-old man presented a painless swelling of the right testis that he has been observing for 3 years. Gross examination of the resected specimen showed an encapsulated, gray to tan colored, roughly rounded tumor. Histologically, the tumor revealed a well-differentiated chondrosarcoma.     

Minnesota multiphasic personality inventory profile of patients with allergic rhinitis

The aim of this study was to investigate the relationship between allergic rhinitis and personality traits in a nonpsychiatric population of proven allergic status. Subjects were assigned to the allergic group (n = 29) and the nonallergic group (n = 29) on the basis of the medical examination, allergic prick tests, and self-reported allergic status. Analysis of Minnesota Multiphasic Personality Inventory Profile (MMPI) profiles showed that male subjects with allergic rhinitis had significantly higher scores on depression, paranoia, and social introversion. Depression, hypochondriasis, and hysteria scores were significantly higher in female subjects. It may be concluded that patients with allergic rhinitis have poorer psychological function compared with the nonallergic subjects.     

Apoptosis in the traumatic and degenerative tears of human meniscus

The apoptotic bodies were observed aging in osteoarthritic cartilage and meniscus but there is still a lack of knowledge in the literature about the relationship between meniscal injury and apoptosis. The aim of this study is to investigate the apoptotic changes on meniscal tears caused by degeneration and trauma. Thirty-eight specimens of human meniscal tissues harvested from cadavers and patients were selected from groups below the age of 40. There were 14 normal meniscal tissues from cadavers in the control group. There were 24 meniscal tissues harvested from patients who had had arthroscopic operations for meniscal tear due to degeneration or trauma. The torn meniscal samples were divided into two groups according to their etiologies, either degenerative or traumatic. Apoptotic cells were investigated in each of the three groups in the histopathological examination. There was statistically significant difference among the groups according to apoptotic index (p < 0.01). The mean indexes of apoptosis in both groups of torn meniscus (group 2 = 0.497 and group 3 = 0.725) were significantly higher than that in the normal tissue (group 1 = 0.237) (p < 0.01) but the difference between groups 2 and 3 was not significant (p > 0.001). This study indicates that an increase in the amount of apoptosis appeared to have a close relationship with meniscal tear caused by either trauma or degenerative changes.     

Severe intestinal graft versus host disease after donor lymphocyte infusion; response to extracorporeal photochemotherapy.

We present a patient with acute myelogenous leukemia who developed severe acute intestinal graft versus host disease (GVHD) after donor lymphocyte infusion (DLI) following non-myeloablative allogeneic peripheral blood stem cell transplantation (allo-PBCT). One month after DLI, patient developed severe abdominal cramps, watery diarrhea without any signs or symptoms of the skin and liver GVHD. Treatment with steroid, cyclosporine A, tacrolimus and mycophenolat mofetil were not effective in controlling intestinal symptoms. Extracorporeal photochemotherapy (ECP), a recently used procedure in the treatment of GVHD was employed periodically and the symptoms subsided gradually. Acute GVHD after DLI may occur severely and atypically, but being limited to the intestine has rarely been reported.     

Psychiatric morbidity among cancer patients and awareness of illness

A significant proportion of cancer patients experience psychiatric morbidity. Potential predictors of psychiatric morbidity include patient disease-related factors and factors relating to the patients environment. The aim of this study was to investigate the prevalence of psychiatric morbidity and the relationship between the clinical or personal factors, especially psychiatric morbidity, and awareness of cancer diagnosis among a group of Turkish cancer patients. A total of 117 cancer patients were assessed using the Structured Clinical Interview for DSM-IV (SCID), the Hospital and Anxiety Depression Scale (HADS) and the General Health Questionnaire (GHQ). Of these patients, 30% had a psychiatric diagnosis. Adjustment disorders comprised most of the psychiatric diagnoses. Awareness of the diagnosis of cancer, history of previous psychiatric disorders, pain and stress factors were correlated with psychiatric morbidity. Of the 117 patients, 64 (54.7%) were unaware of the diagnosis of cancer. Most of the patients (67.9%) who were considered to be aware of the cancer diagnosis stated that they had guessed their illness from the treatment process or drug adverse effects. Psychiatric morbidity was significantly higher in the patients who knew that they had a cancer diagnosis (P=0.03). These findings suggest that the awareness of cancer diagnosis is related to the presence of psychiatric morbidity. In particular, the understanding of the diagnosis indirectly may be stressful to the patient because it arouses suspicion about the cancer and treatment, and consequently can lead to psychiatric disturbance. In Turkey honest disclosure of the true diagnosis is still not common for cancer patients and it seems to be essential to improve this situation.This paper was accepted as a poster presentation at the European Conference of Clinical Oncology (ECCO) Congress held in Copenhagen, 21–25 September 2003.
