Objective: The aim of this study is to investigate the prognostic value of serum acetylcholinesterase levels and their relationship with neurological syndromes (Type 1 syndrome, intermediate syndrome, and delayed polyneuropathy) in acute organophosphate poisoning. Materials and methods: Thirty-two consecutive patients with acute organophosphate poisoning admitted to the Ondokuz Mayis University Emergency Department from June 1999 to January 2001 were evaluated. Patients were assessed according to admission time, symptoms, and results of clinical exams and their serum acetylcholinesterase levels were determined on days 1, 2, 3, 7, and the last day. Results: There was no significant difference between the first-day serum acetylcholinesterase of the patients with severe poisoning (n=22, 68.75%) and of the patients with mild poisoning (n=10, 31.25%; NS). There was no discernible difference between the serum acetylcholinesterase obtained on days 1 and 3 after poisoning from the patients with intermediate syndrome (n=5, 15.6%; means: 0.90±0.65 vs. 0.88±0.53, 19.35 vs. 18.92%; NS, sensitivity=80%; specificity=87.5%). There was a significant difference between the serum acetylcholinesterase obtained on days 1 and 3 from the patients with nonintermediate syndrome (n=24, 75%; means: 1.05±0.24 vs. 1.68±0.29, 22.58 vs. 36.12%; p<0.001). There was no discernible significant difference in serum acetylcholinesterase between the patients with organophosphorus-induced delayed polyneuropathy (n=7, 21.8%) and nonorganophosphorus-induced delayed polyneuropathy. In the patients who died (n=5, 15.6%), serum acetylcholinesterase showed no discernible increase day 1–the last day (means: 0.50±0.25 vs. 0.46±0.26, 10.75 vs. 9.89%; NS). There was a significant difference between the serum acetylcholinesterase levels obtained on days 1 and the last day from the patients who survived (n=27, 84.3%; means: 1.14±0.25 vs. 2.32±0.26, 24.51 vs. 49.89%; p<0.001). Conclusion: In the acute phase of organophosphate poisoning, low serum acetylcholinesterase (>50% of minimum normal value) supports the diagnosis of organophosphate poisoning but it does not show a significant relationship to the severity of poisoning (NS). The serum acetylcholinesterase activity may be a useful parameter in following the acute prognosis of organophosphate poisoning.

The aim of this study was to determine whether there is a relationship between climatic factors and suicidal behavior. A total of 1,119 suicide attempts were collected from hospital records between 1996 and 2001. A clear seasonal variation was seen in suicide attempts in the 15-24, 25-34, and over 65 age groups in men and in the 15-24, 25-34, and 35-44 age groups in women with peaks in the spring and summer. Suicide attempts were more frequent between the hours of 6:00-9:00 pm in males and 3:00-6:00 pm in females. People attempting suicide who have depression, anxiety, or a psychotic disorder usually attempt suicide in the summer. Whereas the monthly averages of humidity, ambient temperature, duration and intensity of sunlight were positively correlated with the number of monthly suicide attempts, cloudiness and atmospheric pressure were negatively correlated. In conclusion, we must keep in mind that suicides and suicide attempts are not only the effect of climatic changes and that the most important component is the individuals ability to deal with conflicts.

The epidemiological distribution and clinical features of 12 cases of Weils disease from Turkey, are reviewed. The disease is most common in male farmers from rural areas. Myalgia and jaundice were recorded in all patients. Signs included vomiting in 9 patients, haemorrhages in 6, and renal function was impaired in 6. Creatine phosphokinase levels were found above normal limits in 75% of the cases. Leptospires were demonstrated with dark-field microscopy in the blood of 9 and in the urine of 5 of these patients. The diagnosis was confirmed with microscopic agglutination test (MAT) as well as with ELISA. Ig M antibodies were detected in 11 (92%) of the patients and is an accurate marker for acute leptospirosis. Penicillin was used for therapy and the outcome was favorable in 10 patients. Two patients died. It should be kept in mind that leptospirosis is an extremely severe disease which requires appropriate examinations at the right moment.

ObjectiveStrongyloides stercoralis is a soil-transmitted intestinal nematode that has been estimated to infect at least 60 million people, especially in tropical and subtropical regions. Strongyloides infection has been described in immunosupressed patients with lymphoma, rheumatoid arthritis, diabetes mellitus etc. Our case who has rheumatoid arthritis (RA) and bronchial asthma was treated with low dose steroids and methotrexate.MethodsA 68 year old woman has bronchial asthma for 55 years and also diagnosed RA 7 years ago. She received immunusupressive agents including methotrexate and steroids. On admission at hospital, she was on deflazacort 5 mg/day and methotrexate 15 mg/week. On her physical examination, she was afebrile, had rhonchi and mild epigastric tenderness. She had joint deformities at metacarpophalengeal joints and phalanges but no active arthritis finding.ResultsOesophagogastroduodenoscopy was performed and it showed hemorrhagic focus at bulbus. Gastric biopsy obtained and showed evidence of S.Stercoralis infection. Stool and sputum parasitological examinations were also all positive for S.stercoralis larvae. Chest radiography result had no pathologic finding. Albendazole 400 mg/day was started for 23 days. After the ivermectin was retrieved, patient was treated with oral ivermectin 200 μg once a day for 3 days. On her outpatient control at 15th day, stool and sputum samples were all negative for parasites.ConclusionS.stercoralis may cause mortal diseases in patients. Immunosupression frequently causes disseminated infections. Many infected patients are completely asymptomatic. Although it is important to detect latent S. stercoralis infections before administering chemotherapy or before the onset of immunosuppression in patients at risk, a specific and sensitive diagnostic test is lacking. In immunosupressed patients, to detect S.stercoralis might help to have the patient survived and constitute the exact therapy.

The aims of this study were to report experience in patients with organophosphate poisoning (OPP) and to discuss the potential role for hemoperfusion (HP) in the management of severe OPP. At the emergency service of a university hospital, 52 patients with acute OPP were included in this retrospective study. The patients were divided into 2 groups (Group 1, severe poisoning, n = 25; and Group 2, mild poisoning, n = 27). All patients with mild OPP survived. Seven patients (28%) of the 25 with severe OPP died. This study supports previous data documenting that HP is unnecessary in the management of mild OPP. Although there was not a control group (severe poisoning without HP treatment) in this study, experience suggests that HP can be useful in severe cases. Reports from centers having experience with severe OPP can help clarify this controversial issue. Randomized controlled (prospective) studies investigating the possible beneficial effects of HP on patient survival in patients with severe OPP with control group are needed.

Strongyloidiasis is a nematode-borne disease caused by several Strongyloides species. This case was presented in order to indicate Strongyloidosis in immunocompromised patients with several clinical findings. A fifty-five year old male patient on corticosteroid medication for a long time because of ankylosing spondylitis was on infliximab medication for 5 years. He presented with swelling of his right foot for ten days, right shoulder stiffness and low back pain. The presence of anaemia was remarkable. S. stercoralis was reported in histological examination of endoscopic duodenal biopsy specimen. Peripheral blood smear showed 68.4% neutrophils, 17% lymphocytes, 7.5% monocytes, and 6.7% (normal range 2%-6.2) eosinophils. The level of IgE was raised: 285IU/mL (normal range 5-120IU/mL). A large number of S. stercoralis larvae were detected upon stool examination with saline and iodine mounts and the formaldehyde ether concentration method. After treatment with two cure albendazole 400 mg/day for 7 days, S. stercoralis larvae were not detected in stool examination. It is interesting that response to treatment was not observed on the first cure and the recovery was seen on the second cure. We suggest that hyperinfections should be taken into consideration in the diagnosis and treatment of immunocompromised patients with several complaints so that life-threatening effects of the nematode may be prevented.

Z. Doğanay; Dursun Aygün; A.H. Şahinoğlu; Levent Altintop; Hakan Güven

Sedation and Analgesia in Emergency Department The aproach of the doctors to the patient in Emergency deparment includes supporting vital functions and treating the main cause. Apropriate treatment of pain and anxiety is inadequate .because of concers of adverse effects and ignorance. But inadequate treatment of pain and anxiety may cause undesirable differences in all systems of the patient. The present paper discusses the necessity of pain and anxiety relief in Emergency Department and some usefull methods and drugs. Acil servise basvuran hastalarda genelde tedavide yaklasim vital fonksiyonlarin desteklenmesi ve olusan patolojinin tedavisidir. Bu sirada gelisen agri ve anksieyete nedense hasta cok fazla yakinmadikca ikinci plana atilir. Cogunlukla da uygulanacak sedatif ve anestezik ilac konusundaki yetersiz deneyimin beraberinde getirdigi korku hastada bu tedavinin eksik kalmasina neden olur. Oysa agn ve anksiyetenin uygun bir sekilde giderilmemesi hastanin tum sistemlerinde istenmeyen degisikliklere neden olur. Bu yazinin amaci acil serviste agn ve anksitenin giderilmesinin gerekliligini vurgulamak ve uygulanabilecek anestezik ilaclann ve yontemlerin sunulmasidir.
