Carbon monoxide poisoning cases presenting with non-specific symptoms

Carbon monoxide (CO) is a colourless and odourless gas appearing as a result of incomplete combustion of carbon-containing fuels. Many domestic or occupational poisonings are caused by CO exposure. Malfunctioning heating systems, improperly ventilated motor vehicles, generators, grills, stoves and residential fires may be listed in the common sources of CO exposure. The aim of this study was to emphasize the significance of early diagnosis of CO poisoning with non-invasive measurement of CO levels of the patients with non-specific symptoms using a pulse oximeter device in the triage. Our study was a cross-sectional study. Patients who presented to the emergency department (ED) due to non-specific symptoms and had a Canadian Triage and Acuity scale level of 4 or 5 were included in the study; 106 (5.9%) of 1788 patients admitted during the study period were diagnosed with CO poisoning. Patients with CO poisoning and the other patients had statistically significant differences in terms of presenting symptoms, namely, headache, dizziness, nausea, and vomiting. More CO poisoning cases were admitted in the fall and winter compared to the spring and summer. The number of CO poisoning victims can be decreased if preventive measures like CO monitoring systems and well-designed ventilation systems are generalized at homes and workplaces. Measurement of carboxyhaemoglobin levels of patients presenting to ED due to non-specific symptoms like headache and dizziness during cold seasons and winter months using a pulse CO-oximeter should be a part of the routine of emergency medicine triage.

Acute intoxication cases admitted to the emergency department of a university hospital

BACKGROUND

This study aimed to describe the clinical and socio-demographic aspects of acute poisoning in 2010 in Duzce City, Northwest Anatolian Region of Turkey.

METHODS

Acute poisoning was due to the intentional ingestion of drugs in young and adult people (≥16), who were treated at the Emergency Service of Duzce University Medical Hospital, Turkey from January 1, 2010 to December 31, 2010. In this retrospective and descriptive study, 95 patients were diagnosed with intoxications and 30 of them intentionally ingested drugs to commit suicide. Records of the patients diagnosed with intoxication were obtained from the Clinical Archive of the hospital. Their diagnoses were established according to the International Statistical Classification of Diseases and Related Health Problems. Codes X60-X84 of this classification were used to classify self-infringed drug injuries and drug poisoning.

RESULTS

In this series, 35 (36.8%) patients were male and 60 patients (63.2%) female. The male/female ratio was 1.0/1.7. The mean age of the patients was 33.1±14.2 years; 17 (17.9%) patients were below 20 years old and 9 (9.5%) were older than 50 years. Of these patients, 29 (30.5%) were single, 7 (7.4%) divorced or separated, and 59 (62.1%) married. Their mean time for admission to the emergency service after the incident was 208±180 (15-660) minutes. The mean time for admission to the emergency service for patients with food intoxication after the incident was 142±160 minutes, for those with drug intoxication 173±161 minutes, for those with carbon monoxide (CO) intoxication 315±209 minutes, and for those with undefined intoxication 289±166 minutes (P=0.005). Most of the intoxication cases occurred in winter (41.1%, 39 of 95 patients). Admissions to the emergency service were most common in December and April (21 and 16 of 95 patients, respectively). Sixty-five (68.4%) cases were involved in non-deliberate poisoning, whereas 30 (31.6%) were involved in deliberate poisoning. Twenty-six of the 95 patients with acute poisonings had mortality risk at admission, however only one died from CO intoxication in the emergency service (1.1%). Suicide attempts were more common in females than in males (21 of 30 patients, 70%, P<0.05).

CONCLUSION

In Duzce City of Turkey, most intoxication cases occurred in winter, especially in December. They had non-deliberate poisoning, but deliberate poisoning in suicide attempts was more common in females than in males.

Effects of photodynamic therapy with verteporfin for the treatment of chronic central serous chorioretinopathy: An uncontrolled, open-label, observational study

BACKGROUND

Central serous chorioretinopathy is an idiopathic disorder that leads to serous neurosensory retinal detachment. The disorder is usually self-limited and resolves spontaneously; however, sometimes neurosensory retinal detachment persists. This form of the disorder is called chronic central serous chorioretinopathy (CCSC).

OBJECTIVE

The aim of this study was to assess the effects of photodynamic therapy (PDT) on visual acuity with full-dose verteporfin for CCSC.

METHODS

The eyes of patients with CCSC were included in the study. Ophthalmic examination including best-corrected visual acuity (BCVA), fundus examination, fluorescein angiography, and optical coherence tomography was performed before treatment and at 1, 3, 6, 9, and 12 months. PDT with full-dose verteporfin (6 μ/m(2) of body surface area) was applied only to areas of active leakage. BCVA was converted to a log of the minimum angle of resolution (logMAR) equivalent for statistical analysis. Central foveal thickness and BCVA between baseline and follow-up were compared.

RESULTS

Seventeen eyes of 16 patients (13 males, 3 females; mean [SD] age, 39.75 [7.51] years; mean duration of follow-up, 13.06 [1.82] months) were used in the study. The mean (SEM) logMAR BCVA was 0.26 (0.07) at baseline and 0.04 (0.02) at 12 months. Mean logMAR BCVA values at baseline (0.259) and after treatment (0.112, 0.053, 0.047, 0.041, and 0.041 at 1, 3, 6, 9, and 12 months, respectively) differed significantly (P = 0.006, P = 0.005, P = 0.005, P = 0.005, and P = 0.005). There was a significant difference in the mean central foveal thickness at the final visit (169 μm) compared with the baseline value (383 μm; P < 0.001). BCVA decreased in one eye (20/20 vs 20/25) and persisted during follow-up; in the other 16 eyes, BCVA either increased (n = 10) or remained stable (n = 6).

CONCLUSIONS

In this small, open-label study, patients with CCSC treated with a single course of PDT with full-dose verteporfin had significant improvement from baseline in BCVA and resolution of subretinal fluid accumulation and active leakage. Treatment was generally well tolerated, but one patient had worsening in BCVA.

Association of vitamin B12 with obesity, overweight, insulin resistance and metabolic syndrome, and body fat composition; primary care-based study

AIM

To investigate correlation of vitamin B12 with obesity insulin resistance, metabolic syndrome.

METHODS

The cross-sectional and primary care-based study was carried out. Anthropometric, blood pressure measurements and bioelectric impedance analysis (BIA) were recorded. Vitamin B12, folic acid, hemogram, insulin, ferritin, iron, total iron binding capacity and other biochemical tests were assayed. The subjects were grouped as obesity, overweight, control, metabolic syndrome (MetS) and insulin resistance (IR). Correlation of vitamin B12 with body mass index (BMI), IR, age, and BIA was evaluated.

RESULTS

The study enrolled 976 patients (obesity: 414, overweight: 212, and control: 351). The mean age in groups of obesity, overweight and control were 35.9 ± 8.7, 28.9 ± 6.3 and 33.1 ± 8.7, respectively (p = 0.142). Vitamin B12 level was significantly lower in patients with obesity and overweight than healthy individuals (178.9 ± 25.2; 219.8 ± 78.5, and 328.5 ± 120.5, p less than 0.001, respectively). Vitamin B12 level was lower in patients with MetS (+/-) and IR (+/-), but insignificant (p = 0.075 and 0.058, respectively). Significant and negative correlation was observed between vitamin B12 and BMI (r =-0.221, p=0.001). No significant difference was observed between obese male and female patients (247.8 ± 89.1 versus 235.5 ± 89.3 pg/mL, respectively, p=0.090).

CONCLUSION

Low Vitamin B12 level was associated with obesity and overweight, but not with insulin resistance, metabolic syndrome and gender. Vitamin B12 was negatively correlated only with body mass index.

N-Acetyl cysteine and erdosteine treatment in acetaminophen-induced liver damage

OBJECTIVE

This study is aimed to investigate the efficacy of erdosteine usage in acetaminophen-induced liver damage and to compare it with N-acetyl cysteine (NAC) in the treatment and prevention of liver toxicity due to overdose of acetaminophen.

METHODS

The rats were separated into the following six groups of seven rats each: control group; acetaminophen (1 g/kg, orally); acetaminophen (1 g/kg, orally) + erdosteine (150 mg/kg/day, orally); acetaminophen (1 g/kg, orally) + NAC (140 mg/kg loading dose, followed by 70 mg/kg, orally); NAC (140 mg/kg loading dose, followed by 70 mg/kg, orally); erdosteine (150 mg/kg/kg, orally), subsequently. In all the groups, potential liver injuries were evaluated using biochemical and hematological analyses, oxidant-antioxidant parameters and histopathological parameters.

RESULTS

In acetaminophen-treated group, levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total oxidant status (TOS) in the blood, prothrombin time (PT) and international normalized ratio (INR) were significantly increased when compared with controls. However, total antioxidant capacity (TAC) and glutathione (GSH) levels were decreased in group treated with acetaminophen, when compared with control group. Levels of AST, ALT and TOS, PT and INR were decreased in groups treated with NAC and erdosteine after acetaminophen administration, but the levels of TAC and GSH were increased. Histopathological improvements were observed in the groups treated with NAC and erdosteine after acetaminophen administration.

CONCLUSION

The present study demonstrated that, in the prevention of liver damage induced by acetaminophen intoxication, an early treatment with a single dose of erdosteine was beneficial instead of NAC administration.

Evaluation of smoking habits among Turkish family physicians

Smoking is still a major public health problem in Turkey. It was aimed to investigate smoking prevalence and habits among Turkish family physicians. Cross-sectional study among physicians working in primary care settings was established. A self-administered study survey was applied. The surveys of 1233 family physicians were analyzed. The study included 704 (57.1%) male and 529 (42.9%) female physicians. Mean age (SD) was 38.94 (7.01) years. The proportions of the current, the former and never smokers among family physicians were 34.1%, 14.7% and 51.3%, respectively. Mean age (SD) of smoking initiation was 21.73 (5.04) years. Mean duration (SD) of smoking use was 14.61 (7.29) years. Proportion of current smoker in male physicians was quite higher than in female counterparts (36.9% vs. 30.4%; p < 0.001). Mean age (SD) of smoking initiation in female was 21.42 (4.59) years, but in male was 22.33 (4.98) years (p = 0.36). In female physicians, mean age (SD) for quitting cigarette smoking was found higher than in male (35.85 (6.35) years vs. 33.09 (6.45) years; p = 0.004). No significant difference between nicotine dependence (mean score (SD) of 3.76 (2.48) vs. 3.65 (2.82); p > 0.05) and mean (SD) unit of cigarette a day (18.34(6.03) vs. 17.17 ± 6.79; p > 0.05) between genders was observed. The number of male physicians who started smoking before faculty was higher than female counterparts (15.5% vs. 8.6%; p = 0.023). In conclusion, the smoking prevalence among Turkish family physicians is considerably high.

To study the correlation between carrier status of nasal Staphylococcus aureus in patients on haemodialysis with hepatitis C, hepatitis B and their sociodemographic features

AIM

To study the correlation of nasal Staphylococcus aureus carrier status in patients on haemodialysis, infected by hepatitis C virus (HCV), hepatitis B virus (HBV), and their sociodemographic features.

SUBJECTS AND METHODS

A survey, including patients' sociodemographic features, was applied to patients by physicians in face to face interviews. Medical records regarding their serologic data were recorded from haemodialysis centres. Nasal swab samples of 2 cm depth from both nostrils of patients were obtained for nasal culture. Samples were inoculated in 5% sheep blood agar and incubated in an incubator at a temperature of 37 degrees C for 24 hours. The results were studied by the same microbiologist.

RESULTS

A total of 185 patients were enrolled in the study. According to culture results, 14.1% of patients (n = 26) had methicillin sensitive Staphylococcus aureus (MSSA) and 1.1% (n = 2) had methicillin resistant Staphylococcus aureus (MRSA). Status of viral hepatitis was 3.8% (n = 8), 10.8% (n = 20) for HBV and HCV respectively. Forty per cent (n = 8) of patients with HBV (+) had MSSA carrier status. Statistically significant positive correlation between MSSA and HCV carrier was detected (r = 0.325, p = 0.001) but not between HBV carrier and MSSA (p = 0.255).

CONCLUSION

In the present study, significant positivity was detected between MSSA carrier status and HCV in patients on haemodialysis and who have lived together with < or = 2 family members at home. Particularly, statistically significant correlation between HCV(+) and MSSA carrier was observed.

Naproxen-induced fixed drug eruption: A case report

Naproxen is a non-steroidal anti-inflammatory drug (NSAID) widely used for symptomatic relief of arthritis and other painful disorders, such as dysmenorrheal. Pruritus is the most common side effect of naproxen. Fixed drug eruption (FDE) due to naproxen is a rarely reported side-effect. No previous report has declared cross-reactivity between naproxen and other propionic acid derivatives. A 28-year-old man, presented with edematous and erythematous patchy lesion along with pruritus and inflammation on lip, have been suffering since 3 hours. It started after taking naproxen 550 mg for headache. On detailed inquiry, he defined similar symptom which recurred after whenever he took naproxen. Based on clinical and histopathological findings, it is evaluated as naproxen-induced FDE. We have tested cross-reactivity between naproxen and other propionic acid derivatives, and then we obtained negative result for oral provocation test with flurbiprofen. Here, we present a case of naproxen-induced FDE of 28-year-old man, by overviewing literatures.

Habitual tea drinking and bone mineral density in postmenopausal Turkish women: investigation of prevalence of postmenopausal osteoporosis in Turkey (IPPOT Study)

AIM

In this epidemiological report, we assessed the prevalence of osteopenia and osteoporosis (OP) in postmenopausal Turkish women and the relationship between body mass index (BMI), and some nutritional factors (habitual tea, coffee, tobacco, and milk product consumption) with OP.

METHODS

This multicenter study was done in postmenopausal women residing in five big cities, in four different regions of Turkey between August and November 2005. An inclusion criterion was being in the postmenopausal period for at least 12 months. A semi-structured questionnaire was completed by face-to-face interview, consisting of closed- and open-ended questions about demographic characteristics, nutritional status, and habits with two or more choices as possible responses. Bone mineral density (BMD) measurements were performed with a MetriScan Densitometer (Alara Inc., CA, USA).

RESULTS

Seven hundred twenty-four women were included in the study. The mean age was 57.6 +/- 9.6 years, and mean age at natural menopause was 46.4 +/- 5.6 years. Of the participants, 51% were illiterate. According to WHO classification; 42.5% were normal in terms of BMD, 27.2% had osteopenia, and 30.2% had OP. Women with high education levels had better T-scores (p = 0.019). Increase in BMI also had a positive effect on T-scores (p < 0.0001). A linear correlation was found between age (r= -0.386, p < 0.0001), BMI (r = -0.175, p < 0.0001), and education (r = -0.317, p < 0.0001), with T-scores. The T-scores of women who consumed tea on a regular basis were found to be higher than non-consumers (-1.51 +/- 1.68 vs. -1.09 +/- 1.66; p = 0.070) [when smokers, those who received hormonal therapy (HT), and those > 65 years were excluded].

CONCLUSION

OP was determined in 1/3 of the women. Advanced age (> 65) and being illiterate were negative factors, while high education levels, being overweight, and being treated with HT had a positive effects on BMD. Habitual tea drinking also may have a positive effect on BMD. However, tea drinking was not found to be a statistically significant factor in the present study.

The evaluation incidence and risk factors of mortality among patients with end stage renal disease in southeast Turkey

AIM

End stage renal disease (ESRD) presents with higher morbidity and mortality with respect to the general population. In recent study, the causes of mortality and associated risk factors in ESRD have been evaluated.

MATERIALS AND METHODS

In this study, 1538 patients diagnosed with ESRD in 10-year period were evaluated retrospectively. The patients were divided as dead (group 1) and alive (group 2). The patients' demographic features, causes of death, comorbidity at hospitalization, hematological and biochemical analyses, creatinine clearance at the beginning of hospitalization, daily urine volume, blood gas results, CRP value as inflammatory marker, ejection fraction, interventricular septum diameter, left ventricle posterior wall end-diastolic diameter, and left atrium diameter determined with echocardiography were recorded.

RESULTS

Mortality ratio of ESRD patients in a 10-year period was 14.1%. While the general mean age of all patients was 54.7 +/- 16.6 and male/female ratio was 781/757, these ratios were 66.3 +/- 21.8 and 114/103 in Group 1 and 52.8 +/- 21.7 and 667/654 in Group 2. One or more comorbid pathologies were present in 82.9% of Group 1. The most common cause of mortality was cardiovascular diseases (CVD), and the most common cause of comorbidity was infections. Older age, anemia, absence of residual renal function, hypoalbuminemia, inflammation, impaired Ca and P metabolism, and left ventricular hypertrophy were significantly higher in Group 1 than in Group 2.

CONCLUSION

CVD are the most important preventable causes of morbidity and mortality in all stages of chronic kidney disease. Taking precaution against CVD and the associated complications will provide a positive contribution in reducing morbidity and mortality among ESRD patients.

CHRONIC FATIGUE SYNDROME AMONG NURSES AND HEALTHCARE WORKERS IN A RESEARCH HOSPITAL IN TURKEY

Chronic fatigue syndrome (CFS) among nurses and healthcare workers was evaluated via a questionnaire examining CFS, sociodemographic factors, lifestyle, work capacity and education. The criteria of the Centers for Disease Control were applied. One hundred and eighty-three nurses and 18 healthcare workers (mean age 29.04 ± 5.31 years) participated. More than half of cases (n = 116, 57.7%) complained of fatigue. Thirty-six cases (17.9%) fully matched the criteria of the CDC for CFS. High income level (> 400/month) (p = 0.005) and overworking (> 8 hr/day) (p = 0.017) had a significant effect on CFS [high income (OR: 9.60, CI, 95%: 1.98 – 46.54) and overworking (OR: 7.66, CI, 95%: 1.44 – 40.92), respectively]. CFS was also related to being under 35 years old.

An evaluation of articles in international peer-reviewed publications in Turkish family medicine

BACKGROUND

Scientific publication in Turkish family medicine (FM) has currently increased and a systematic assessment of the quantity and quality of the published research is the aim of this study.

MATERIAL/METHODS

The data were obtained from the Institute for Scientific Information Citation Databases (SCI, SCI-Expanded, SSCI, and A&HSCI) and the period between 1975-2005 was searched. Key words such as "family practice", "family medicine", "primary care", "primary medical care", and "Turkey" were used and publications were classified according to the type of research, the number of authors, first authorship, the number of citations, and address. The classification was performed by two investigators and the inter-rater-reliability was found to be Cramer's V=0.79 (p<0.05).

RESULTS

One hundred five publications were found. Publications were evident since the year 1991 and showed an increase with the year 2001. The median number of authors of the publications was five (range 1-8), and family physicians were generally the second authors (range: 1-7). The predominant types of publication was research articles (n=72, 69%), and the leading types of research were surveys (n=29, 28%) and case-control studies (n=24, 23%). The median citation number of publications per article was 0.89 (range: 0-13).

CONCLUSIONS

A recent increase in publication in international peer-reviewed journals was observed. Mostly research articles were published, but randomized controlled trials were in the minority. More emphasis on developing a research capacity in family medicine might help to optimize research activities in Turkey.

[Epidemiological characteristics of electrical injuries of patients applied to the emergency department]

BACKGROUND

In this study, we planned to determine the factors affecting the mortality, and morbidity of electrical injuries.

METHODS

Medical records of 165 patients (126 males; 39 females; mean age 21.1 years; range 2.5 to 62 years), who were admitted to the Emergency Department of Dicle University School of Medicine for electrical injuries, between January 2003 and April 2004, were retrospectively reviewed.

RESULTS

Among these patients, 60 (36.4%) were children, under 12 years old; 95 (57.6%) were adolescents and adults, and 10 (6%) were aged. Of the victims of electrical accidents, 29 (17.6%) were illiterate and 36 (21.8 %) were educated. Ninety-seven (58.8 %) patients were either graduates or still students of elementary, secondary or high school. The cause of exposure to electricity was accident in 99 (60%), and carelessness and parents' negligence in 66 (40%). Sixty-nine (41.8%) patients were exposed to high voltage, and 96 (58.2 %) to low voltage. Because of electrical injury 16 patients had first degree, 96 patients had second degree, and 86 patients had third degree burns. The most frequent complications were contractures of extremities (10.9%) and compartment syndrome (3.6%). Mortality rate was 9.1% (n=15). Eighty percent of the deaths were due to exposure to high voltage. A positive correlation was demonstrated between mortality and complications (p<0.001). Escarotomy was performed in 10 patients, fasciotomy in 16, and amputation in 9. Two of 5 patients who had intraabdominal hemorrhage underwent surgery.

CONCLUSION

A serious education of the society with respect to conscious use of electricity is the most efficient method to decrease electrical accidents.

Factors affecting mortality and epidemiological data in patients hospitalised with burns in Diyarbakir, Turkey

BACKGROUND

Burns continue to be responsible for significant morbidity and mortality in developing countries. In this study we aimed to determine the factors affecting mortality and epidemiological data by examining the records of burned patients.

METHOD

The hospital records of 980 patients who were hospitalised in the Burns Unit at Dicle University Hospital (DUH) between June 1994 and July 1999 were examined for factors affecting mortality. Factors evaluated included gender, age, burn type, degree and extent of burn, prognosis and length of hospitalisation (LH). We investigated the relationship (if any) between the demographic data, degree and extent of burns and mortality and morbidity rates.

RESULTS

The study group consisted of 325 males (33.2%) and 655 females (66.8%). Of the patients 738 (75.3%) were children (age under 15 years), 217 (22.1%) were younger adults (age 15-50 years), and 25 (2.6%) were older adults (age over 50 years). The mean age was 11.2 +/- 14.01 years (range 15 days-95 years). Of the burns 618 (63.1%) were scalds, 199 (20.3%) burns from a flame and 163 (16.6%) electrical burns. The mean extent of burn was 24.3 +/- 14.5% (range 1-95%). Seven hundred and eighty-seven (80.3%) of the study group made a full recovery, 131 (13.4%) were discharged from hospital after partial recovery, and 62 (6.3%) died. The mean LH was 11.33 +/- 8.8 days (range 1-67 days). There was a positive correlation between burn extent and mortality (r = 0.35, p < 0.0001) and between age and type of burn (r = 0.60, p < 0.0001). While scalds had the highest frequency among children, flame and electrical burns were most common in the adult and older adult groups. There was also a positive correlation between degree and type of burn (r = 0.32, p = 0.0001), scalds tending to be more superficial while flame and electrical burns were generally more serious. Deaths of patients with extensive burns usually occurred in the first 5 days following injury due to acute renal failure and hypovolaemic shock, while deaths from moderate and minor burns usually occurred after 7 days and were due to wound infection and sepsis.

CONCLUSION

We found positive correlations between age and type of burn, degree and type of burn, and the extent of burn and mortality. The overall mortality rate for our unit was 6.3%.

An epidemic caused by measles virus type D6 in Turkey

In this study, the extent of measles outbreak was investigated in the Idil and Cizre counties of Sirnak Province. New cases determined in patients who applied to primary care clinics and those detected during home visits were evaluated. In 2001, a total of 2,143 cases reported in Sirnak Province were signified as a probable outbreak. Three hundred and thirty-three patients in Cizre and 219 patients in Idil applied to the primary care clinics. Of the cases, in Cizre 8.4% (n=28) and in Idil 6.4% (n=14) were infants aged nine months and younger who had not yet been vaccinated. Totally, 17 new cases (8 in Cizre and 9 in Idil) in the exanthema phase were determined during home visits and these were considered as outbreak cases. Virus isolation was achieved in 12 cases. All isolates were sent to the Centers for Disease Control (CDC) for genotyping and classified as D6 group. In conclusion, measles epidemics are still seen in our country. Therefore, measles outbreaks necessitate intensive intervention by physicians who are employed in primary health care services.

Acute poisoning cases admitted to a university hospital emergency department in Diyarbakir, Turkey

AIM

This study was conducted to determine the biological effects of acute poisoning, the nature of agents involved and the pattern of poisoning in Diyarbakir City, in the Southeast Anatolian region of Turkey, during 2000.

METHOD

Hospital records of all admissions to the Emergency Department (ED) of Dicle University Hospital following acute poisoning were revised and all data from January to December 2000 were analysed. The present study included 44 (25.9%) male (M) and 126 (74.1%) female (F), a total of 170 patients. The M/F ratio was 1.0/3.5.

RESULTS

The mean age of patients was 23.3+/-6.3 years; 63 (37.1%) of them were under 20 years of age and 147 (86.5%) were under 30 years of age. Most intoxication cases occurred during the summer season (93 of 170 patients). On a monthly basis, admissions during April, May and July were most common (24, 26 and 30 patients, respectively). Sixty-two (36.5%) cases involved accidental poisoning while 108 (63.5%) involved deliberate poisoning. In suicide attempts, intoxications were more common in females (77 cases, 71.3%, P < 0.05), and in unmarried persons (74 cases, 68.5%, P < 0.05). There were only two deaths (1.2%) among the 170 admissions of acute poisonings. One of the deaths was due to pesticide poisoning and the other was due to medical drug abuse. Tachycardia (59, 34.7%), vomiting (55, 32.4%) and loss of consciousness (42, 24.7%) were frequently observed, whereas hypersecretion (15, 8.8%), bradycardia (5, 2.9%), convulsion (8, 4.7%) and hypertension (2, 1.2%) were less frequent. Among pesticide poisoning cases the incidence of convulsion (6, 10.2%), miosis (6, 10.2%), and hypersecretion (12, 20.3%) were significantly higher when compared to other cases (P=0.018, P <0.0001 and P <0.0001, respectively).

CONCLUSION

In the Southeast Anatolian region of Turkey, pesticide intoxication is common especially among young, unmarried females and most of these intoxications are intentional self-poisonings. The annual rate of poisoning-related ED visits and mortality were found to be within expected ranges; psychoactive agents being the most common cause.

The evaluation of immune responses that occur after HBV infection and HBV vaccination in hemodialysis patients

The hepatitis B virus (HBV) vaccination never lose its importance; however, we did not get immune response with vaccination in some cases at the hemodialysis (HD) units. In this research, our aim was to evaluate antibody responses that constitute with natural ways and vaccination against HBV infection in chronic HD patients. In this retrospective cohort study (between 1999 February and 2001 December), 34 patients, 19 males and 15 females that were at the HD program, were enrolled. Patients were divided into two groups: group A, vaccination group (n = 15); and group B, anti-HBc IgG (+) cases (n = 19). We injected 40 microg of recombinant HBV vaccine into the deltoid muscle at 0, 1, 2, and 6 months. The anti-HBs levels, over 10 mIU/mL, were accepted for enough immunization. In group A, after vaccination 12 of 15 (80%) patients had seroconversion but later, in five of 12 (33.3%) patients, HBs-antibody became negative and in seven of 12 (46.7%) patients the positivity of HBs-antibody continued. However, in group B, 16 of 19 (66.7%) immune patients who faced HBV infection, it was established that antibody response continued (P > 0.05). The patients in group A who had anti-HCV negativity and serum albumin levels >/=3.5g/dL (7/0; P < 0.05) had too much antibody response against the vaccine. The difference of our research was that patients under 49 years old, patients who did not respond to HBV vaccine, were proportionally higher as compared to those from other researches. In conclusion, it was realized that the immune response of the HBV vaccine was low in the HD patients and it was affected by several factors such as gender, anti-HCV positivity and nutritional status. But, in spite of getting all universal precautions, still to face with new cases emphasizes the importance of the vaccination.

Insulin Response to Oral Glucose Loading and Coronary Artery Disease in Nondiabetics

Hyperinsulinemia is related to coronary artery disease (CAD), as an indication of decreased insulin sensitivity. Although there are many studies showing the relation between fasting insulin levels and insulin resistance, there are fewer studies on postprandial insulin levels. The aim of the present study was to investigate the relationship between postprandial insulin levels and CAD and its extent in our patients. For this purpose, oral glucose tolerance testing was performed in 222 patients with no known diabetes and who were scheduled to undergo diagnostic coronary angiography. The patients were first separated into two groups, one group (group I) having an insulin response within reference values to oral glucose loading, and the other group (group II) with a higher than normal insulin response. The presence and extent of CAD in the two groups were compared. While 65% of the patients in group 1 had CAD, this rate increased to 79% in group 2 patients (P = 0.02). The mean vessel scores were 0.92 +/- 0.78 in group 1 and 1.67 +/- 0.99 (P < 0.0001) in group 2 patients. The stenosis scores were 2.192 +/- 2.077 in group 1 and 5.588 +/- 3.519 (P < 0.001) in group 2, while the extent scores were 1.230 +/- 1.292 in group 1 and 2.729 +/- 1.847 in group 2 (P < 0.0001). The differences between the two groups were significant. Postprandial insulin values were positively correlated with CAD (P = 0.001, r = 0.214), vessel scores (P < 0.0001, r = 0.326), stenosis scores (P < 0.0001, r = 0.261), and extent scores (P < 0.0001, r = 0.419). Logistic regression analysis revealed hyperinsulinemia increased CAD independent from the other risk factors (OR = 5.742, CI 95%: 1.809-18.227, P = 0.003).

The evaluation of postdialysis L-carnitine administration and its effect on weekly requiring doses of rHuEPO in hemodialysis patients

BACKGROUND

In this study, our aim was to evaluate the effect of postdialysis administration of parenteral L-carnitine supplementations on hematological parameters and also on weekly requiring dose of the recombinant human erythropoietine (rHuEPO) in hemodialysis (HD) patients.

MATERIAL AND METHODS

The stable 34 patients (17 male, 17 female) were enrolled in the study who were on rHuEPO therapy and a regular maintenance HD program at 5 h, three times a week with bicarbonate dialysate and with biocompatible membranes in HD Center of Medical Faculty Hospital in University of Dicle. rHuEPO was administered subcutanously at 80-120 U/kg/week. The patients were divided into two groups: Group 1, rHuEPO therapy (n=17) and Group 2, rHuEPO therapy + L-carnitine (n=17). L-carnitine (L-carnitine ampul, Santa Farma) 1 g was injected postdialysis intravenously via venous route of the dialytic set, three times a week. The patient's hemoglobin (Hgb), hematocrit (Hct), serum iron (Fe(+2)), total iron-binding capacity (TIBC), transferrin saturation index (TSI), and serum ferritin (Fer) levels were followed during the 16-week period. The weekly requiring doses of rHuEPO and hematological parameters of patients were recorded at the beginning of the study, at 8 weeks, and at 16 weeks of the study period.

RESULTS

In group 1 (n=17, 13 female, four male), the mean age was 38.8 +/- 12.1 years, mean period time on HD therapy was 18.1 +/- 14.9 months, and mean Kt/V value was 1.48 +/- 0.28. In group 2 (n=17, 13 male, four female), the mean age was 48.1 +/- 15.4 years, mean period time on HD therapy was 34.4 +/- 23.0 months, and mean Kt/V value was 1.29 +/- 0.20. The hematological parameters of the groups were found as follows: in group 1, Hgb: 7.9-10.8 g/dl, Hct: 25.3-32.5%; in group 2, Hgb: 10.2-11.8 g/dl, Hct: 30.6-35.4%, respectively (p < 0.05). The target Hgb/Hct values were achieved at the end of the study in both groups. Both groups were the same according to their serum Fe(+2) markers (p > 0.05). But unlike serum Fe(+2) markers, there were significant differences on weekly requiring doses of rHuEPO therapy between groups. While in group 1, the mean weekly requiring dose of rHuEPO was 6529 U/week (120 U/kg/ week) at the beginning of the study, and maintenance weekly requiring dose of rHuEPO was 3588 U/week (66 U/kg/week) at the end of the study, in group 2, they were 4882 U/week (80 U/ kg/week), and 1705 U/week (28 U/kg/week), respectively. According to these values, the total reduction in weekly requiring dose of rHuEPO was 45% in group 1, and 65% in group 2; the net gain was 20% in group 2 (p < 0.05).

CONCLUSIONS

If other factors related to anemia are excluded, the postdialysis parenteral L-carnitine therapy can be considered in selected stable patients, which may improve anemia and may reduce the weekly requiring dose of the rHuEPO and also be cost-effective.

The prevalence of insulin resistance and its relationship between anemia, secondary hyperparathyroidism, inflammation, and cardiac parameters in chronic hemodialysis patients

BACKGROUND

Insulin resistance (IR) frequently accompanies end-stage renal disease (ESRD). There is a positive correlation between IR and cardiovascular pathologies that plays a role in mortality and morbidity on patients with ESRD. We aim to research the prevalence and evaluability of homeostasis model assessment-insulin resistance (HOMA-IR) in hemodialysis (HD) patients and also to evaluate the relationship of this value with various clinical parameters.

MATERIAL AND METHODS

57 ESRD patients, regularly undergoing HD were enrolled in the study. Obese patients (BMI > 25 kg/m2) and ESRD patients with diabetic etiology were excluded. Twenty-nine patients were men (50.9%), and 28 patients were women (48.1%); the mean age was 45.9 +/- 13.6 years. Results were recorded after evaluated by HOMA-IR. In addition to calculating the HOMA index, anthropometrical parameters, plasma levels of total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), hematocrit (hct), parathyroid hormone (PTH), calcium (Ca), phosphorus (P), C-reactive protein (CRP), fasting glucose, and insulin plasma levels were measured by standard methods in all subjects. The systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure were recorded, and left ventricle posterior wall thickness was measured by echocardiography. All patients completed the study. The minimum HOMA-IR value was 0.11, maximum value was 5.18, and the cut-off point was 1.23. According to this value, the patients were classified into two groups: HOMA-IR positive that were equal or higher than 1.23 (group 1), and HOMA-IR negative that were under this value (group 2).

RESULTS

We established that 18 of 57 (31.6%) patients were HOMA-IR positive and 39 of 57 (68.4%) patients were negative. In group 2, hct levels were higher than in group 1 and the weekly requiring dose of rHuEpo was significantly low in group 2 compared with group 1 (p < 0.05). Interestingly, the Ca x P products (> or =55 mg/dL) were significantly higher in group 2 than in group 1 (p < 0.05). There was not any significant correlation between HOMA-IR and anthropometrics measurements, hemodialysis adequacy, plasma PTH level, cardiac parameters, and inflammation markers. We established the prevalence of IR as 31.6% in our HD patients' cohort.

CONCLUSIONS

There was a positive correlation between low HOMA-IR value with target hct levels and administration of the rHuEpo. Because insulin resistance is an independent risk factor of cardiovascular mortality in ESRD patients, it was accepted that being able to correct the insulin resistance could be a novel therapeutic approach in this cohort.

The relation of Helicobacter pylori with intestinal metaplasia, gastric atrophy and BCL-2

BACKGROUND/AIMS

It is assumed that the sequence of events in gastric cancer is as follows: chronic gastritis, atrophy, intestinal metaplasia (IM), dysplasia, and carcinoma. It is also known that Helicobacter pylori (Hp) can be involved in the chain of these chronic phenomena. Therefore, we studied the relation of Hp with chronic inflammation, atrophy, activity level, IM and bcl-2.

METHODS

The number of patients included in this study was 52; 35 (67.3%) were female and 17 (32.7%) were male. The average ages of women and men were determined as 44.5 and 41.5 years, respectively. Hp was determined in 53.8% of all cases and chronic inflammation was found in all cases. No dysplasia or gastric cancer was found in our cases. A statistically significant positive correlation was found between the Hp intensity and the degrees of chronic inflammation, atrophy and activity.

RESULTS

Bcl-2 was found positive in 7.1% of the patients with Hp, and in 4.1% of the Hp-negative patients. However, bcl-2 was positive in 2 (8.7%) of 23 Hp-positive patients with chronic atrophic gastritis and in 1 (11.1%) of 9 Hp-negative patients with chronic atrophic gastritis. In other words, bcl-2 was found more in Hp-negative chronic atrophic gastritis than in Hp-positive chronic atrophic gastritis. Also, atrophy and IM were present together in 2 bcl-2-positive patients in whom Hp was positive. Bcl-2 was found positive more in IM than atrophy, proportionally. According to these data, although bcl-2 was found positive more often in Hp (+) cases proportionally, it was not statistically significant. Nevertheless, no significant difference was found between bcl-2 positivity and atrophy according to the statistical data. The data regarding the relation between IM and bcl-2 were statistically significant, and a positive correlation was found between them.

CONCLUSIONS

We concluded that Hp infections result in chronic gastritis, have a role in the development of atrophy and IM, and that Hp infection has a significant relation with neutrophile activation. The more Hp intensity increases, the greater the degrees of chronic gastritis, activity and atrophy. We also found that Hp, which is known to increase apoptosis, increases the expression of bcl-2, an anti-apoptotic gene, not directly but rather by causing atrophy development. We observed more bcl-2 positivity in IM than in atrophy. Further studies with an extensive series of cases, including patients with dysplasia and gastric cancer, are needed to clarify statistical rates and to support the suggestion that bcl-2 expression increases with the progression to gastric cancer.

Transmission of hepatitis C by blood splash into conjunctiva in a nurse

The risk of transmission of hepatitis C virus (HCV) infection is an important problem for the health care worker. HCV transmission by blood splashing into eyes is very rare. In a hemodialyses department, a 23-year-old female nurse splashed blood from a patient who was anti-HCV positive into her eyes. She washed her eyes with water immediately and reported to the infection control department. She had never used intravenous drugs nor received transfusions. At the time of exposure, there was no abnormality in her laboratory tests. Her anti-HCV and HCV-RNA tests produced negative results. She was followed up for anti-HCV and alanine aminotransferase activity. After 6 months, she presented with sore throat, nausea, vomiting, fatigue, and weight loss. She had icterus and hepatomegalia. In laboratory tests, alanine aminotransferase level was 504 U/L, aspartate aminotransferase level was 388 U/L, and anti-HCV and HCV-RNA tests produced positive findings. She was treated with interferon alfa-2a for a 1-year period. After treatment, an HCV-RNA test produced negative results and transaminase levels were normal. In conclusion, splashing blood from patients who are HCV positive into the face or eyes is a risk for health care workers. They should be educated to prevent a nosocomial acquisition of bloodborne infection and they should observe protective precautions.

Depression in dialysis patients

Many psychiatric disorders can be seen in patients with chronic renal failure (CRF). Haemodialysis (HD), which is a renal replacement treatment, causes various psychiatric and psychosocial problems. Patients are dependent on treatment and the illness causes various problems. In addition, strict diet and continuous treatment are other stress factors (1,2). Various studies have been published in different regions and countries about the prevalence of depression and the relation between sociodemographic factors and depression in patients treated by continuous ambulatory peritoneal dialysis (CAPD), which has gradually become common in Turkey. However studies, which reflect the authors' region, have become necessary (2,3).

Effectiveness of collagenase in the treatment of sacrococcygeal pilonidal sinus disease

PURPOSE

Sacrococcygeal pilonidal sinus disease (SPSD) is a disease affecting young patients, which results in a long-term loss of productive power, and also tends to have high rates of morbidity since it has no ideal treatment. The main purpose of this study was to investigate the effectiveness of topical collagenase in the treatment of SPSD.

METHODS

In the present study, 40 patients admitted to our department were separated into two groups. Excision and marsupialization with dressing by bacterial collagenase was performed in the first group, while the treatment was excision and marsupialization without dressing by bacterial collagenase in the second group.

RESULTS

We determined that the healing in terms of the width and depth of the wound in the first week and in depth of wound in the second week was better in group 1 than in group 2 ( P = 0.040, P = 0.020, P = 0.048, respectively). The duration of wound healing was 21.9 +/- 1.3 days in group 1, and 28.1 +/- 1.3 days in group 2 ( P = 0.0001). The recurrence rate in the intergluteal area, which heals by granulation and has no hair follicles, tends to decrease when a partial closure is obtained.

CONCLUSION

We therefore recommend an excision, marsupialization, and dressing with bacterial collagenase, in cases with noncomplicated SPSD.

Sociodemographic, clinical, and laboratory features of cases of organic phosphorus intoxication who attended the Emergency Department in the Southeast Anatolian Region of Turkey

In this study, sociodemographic, laboratory, and clinical features of cases of organic phosphorus (OP) intoxication in the Southeast Anatolian region of Turkey were investigated. Patients with OP intoxication admitted to the Emergency Service of Dicle University Hospital in Diyarbakyir City between May and August 1998 were evaluated. This prospective cohort study included five male (M) and 19 female (F) consecutive patients. Five cases were accidental intoxication; however, 19 cases were suicide attempts. Mean age of cases was 24+/-11 years; 54.2% of them were under the age of 20 years and 83.3% of them were under the age of 30 years. The M/F ratio was 1.0/3.8. The cases of suicidal purposeful intoxications were mostly determined in singles (58.3%, P<0.05). Most of the cases had a primary education level (16, 66.7%) and a lower socioeconomic status (14, 58.3%); 79.2% of cases admitted to our emergency service received atropine in primary health care centers. In emergency service, pralidoxime (PAM) was administered to only 29.2% of cases. According to ECG examination, tachycardia (14, 58.3%), ST changes (13, 54.2%), and T changes (3, 12.5%) were mostly seen; bradycardia and serious ventricular arrhythmias were not seen in any case. Patients who received atropine plus PAM had higher rates of arrhythmias, but this was not statistically significant (P>0.05). The most observed biochemical features of cases were leukocytosis (21 cases), hypokalemia (18 cases), and hyponatremia (4 cases). Other biochemical features were not evidently altered. In present cases, the most frequently seen symptoms and findings were vomiting (18, 75%), feeling faint (17, 70.8%), and tachycardia and dozing off (14, 58.3%). Serious ventricular arrhythmias were not observed, and in our region, OP intoxication especially affected young unmarried females, and most of them resulted from a suicidal purpose.

Acute accidental exposure to chlorine gas in the Southeast of Turkey: a study of 106 cases

The present study reports a thorough investigation of the sociodemographic characteristics, clinical findings, and treatment of persons affected acutely by chlorine gas exposure from a chlorine tank belonging to the municipality of Diyarbakir. One hundred six persons were assessed. In this cross-sectional study, 58 patients were male and 48 were female. Children and adolescents younger than 18 years constituted more than half of the patients (60 cases, 56.6%). The age of patients ranged between 3 months and 75 years. Among the cases evaluated in emergency rooms, 7 patients had mild poisoning and were discharged after first examinations and symptomatic treatments, 62 patients were moderately affected and were taken under observation, and the remaining 37 were severely affected and were hospitalized. In physical examinations, 29 patients had expiratory wheezing, and 1 had tachycardia and extrasystoles. There were no deaths among these patients, acute chlorine intoxication affected mostly children. Respiratory tract findings were predominant in most of the patients. Steroid and bicarbonate applications were inadequate supportive therapies. Humidified O(2) and beta-agonist applications were most useful in the therapy of acute chlorine intoxication.

Interferon-alpha therapy in idiopathic thrombocytopenic purpura

BACKGROUND

Acute idiopathic thrombocytopenic purpura (ITP) represents the most frequent hemorrhagic diathesis in childhood. Up to 30% of patients with ITP are regarded as refractory to standard therapy. The rare mortality from acute ITP in childhood is almost exclusively due to intracranial hemorrhage. This complication occurs in less than 1% of ITP patients. This study was designed to evaluate the effect of alpha-interferon (IFN-alpha) in eight patients whom did not respond to conventional therapy.

METHOD

In spite of conventional therapies, the patient whose platelet count could not be increased to 50;10(9)/L were accepted as refractory ITP. Eight of these patients whose platelet count lower than 20;10(9)/L were included in the prospective cohort study. Interferon alpha 2b 5 MU/m(2) was administered subcutaneously three times a week, totalling 12 times in a month. According to the platelet count on the 28th day of therapy, we grouped the patients into three categories. After 60 days, the survey was re-evaluated according to the platelet count.

RESULTS

The mean age of children was 3.5+/-2.5 (ranged between 3.5 and 9) years. Six of them were boys and two were girls. There was no response in one patient, partial response in one, and good response in six patients on the 28th day of therapy. The maximum rise in platelet count was observed from 7 to 14 days after the initiation of interferon. The median platelet count which was 15+/-5;10(9)/L before therapy, raised to 60+/-12;10(9)/L after therapy. However, on the 60th day of therapy, there were only two patients who had a platelet count over 100;10(9)/L.

CONCLUSION

In our study, we did not observe the long-term benefit of IFN-alpha therapy in refractor ITP in childhood. However, in good responding patients, platelet levels were increased in a short time. Alpha-interferon may be alternative therapy for patients whom had a platelet count below 20;10(9)/L and not responding to standard therapy, or for patients whom immunosuppressive therapy is contraindicated.

Lamivudine and interferon-alpha combination treatment of childhood patients with chronic hepatitis B infection

BACKGROUND

The aim of our study was to compare the efficacy of combined interferon-alpha and lamivudine in children with chronic hepatitis B infection and two durations of treatment (6 and 12 months).

METHODS

Combination of interferon-alpha 2b (10 MU/m2 of body surface) and lamivudine 4 mg/kg (maximum, 100 mg) were given synchronously to 30 patients for 6 months (Group 1) and to 27 patients for 12 months (Group 2). Biochemical, virologic and serologic features were compared between two groups at the end of therapy and 6 months after therapy.

RESULTS

Hepatitis B e antigen clearances were 33 and 59% at the end of treatment and 37 and 56% 6 months after therapy in Groups 1 and 2, respectively (P > 0.05). Hepatitis B virus DNA clearances were 97 and 100% at the end of treatment and 97 and 96% 6 months after therapy in Groups 1 and 2, respectively (P > 0.05). In both groups normalization of alanine aminotransferase was maintained at the end of therapy and 6 months after therapy (P < 0.05). Sustained complete responses were obtained in 20 and 37% of patients at the end of therapy and 6 months after therapy, respectively (P = 0.07).

CONCLUSIONS

When the combination of large dosage interferon-alpha 2b and lamivudine therapy in children was compared at the end of therapy and 6 months after therapy, normalization of alanine aminotransferase and the clearances of hepatitis B e antigen and hepatitis B surface antigen in both groups were directly proportional to the duration of treatment. However, the higher complete response rate at 12 months of combination therapy was not statistically different from that at 6 months.

Predisposing factors for delirium in the surgical intensive care unit

BACKGROUND

Delirium is a sign of deterioration in the homeostasis and physical status of the patient. The objective of our study was to investigate the predisposing factors for delirium in a surgical intensive care unit (ICU) setting.

METHOD

Between January 1996 and 1997, we screened prospectively 818 patients who were consecutive applicants to the general surgery service of Dicle-University Hospital and had been kept in the ICU for delirium. All patients were hospitalized either for elective or emergency services and were treated either with medication and/or surgery. Suspected cases of delirium were identified during daily interviews. The patients who had changes in the status of consciousness (n = 150) were consulted with an experienced consultation-liaison psychiatrist. The diagnosis of delirium was based on Diagnostic and Statistical Manual of Mental Disorders (revised third edition) criteria and established through psychiatric interviews. Patients were divided into two groups: the "delirious group" (DG) (n = 90) and the "non-delirious group" (NDG) (n = 728). During delirium, all abnormal findings related to physical conditions, laboratory features, and additional diseases were evaluated as probable risk factors of delirium.

RESULTS

Of 818 patients, 386 (47.2%) were male and 432 (52.8%) were female. Delirium developed in 90 of 818 patients (11%). The cases of delirium in the DG were more frequent among male patients (63.3%) than female patients (36.7%) (chi2 = 10.5, P = 0.001). The mean age was 48.9 +/- 18.1 and 38.5 +/- 13.8 years in the DG and NDG, respectively (t = 6.4, P = 0.000). Frequency of delirium is higher in the patients admitted to the Emergency Department (chi2 = 43.6, P = 0.000). The rate of postoperative delirium was 10.9%, but there was no statistical difference related to operations between the DG and NDG (chi2 = 0.13, P = 0.71). The length of stay in the ICU was 10.7 +/- 13.9 and 5.6 +/- 2.9 days in the DG and NDG, respectively (t = 0.11, P = 0.000). The length of stay in hospital was 15.6 +/- 16.5 and 8.1 +/- 2.7 days in the DG and NDG, respectively (t = 11.08, P = 0.000). Logistic regression was used to explore the associations between probable risk factors and delirium. Delirium was not correlated with conditions such as hypertension, hypo/hyperpotassemia, hypernatremia, hypoalbuminemia, hypo/hyperglycemia, cardiac disease, emergency admission, age, length of stay in the ICU, length of stay in hospital, and gender. It was determined that conditions such as respiratory diseases (odds ratio [OR] = 30.6, 95% confidence interval [CI] = 9.5-98.4), infections (OR = 18.0, 95% CI = 3.5-90.8), fever (OR = 14.3, 95% CI = 4.1-49.3), anemia (OR = 5.4, 95% CI = 1.6-17.8), hypotension (OR = 19.8, 95% CI = 5.3-74.3), hypocalcemia (OR = 30.9, 95% CI = 5.8-163.2), hyponatremia (OR = 8.2, 95% CI = 2.5-26.4), azotemia (OR = 4.6, 95% CI = 1.4-15.6), elevated liver enzymes (OR = 6.3, 95% CI = 1.2-32.2), hyperamylasemia (OR = 43.4, 95% CI = 4.2-442.7), hyperbilirubinemia (OR = 8.7, 95% CI = 2.0-37.7) and metabolic acidosis (OR = 4.5, 95% CI = 1.1-17.7) were predicting factors for delirium.

CONCLUSION

We determined that conditions such as respiratory diseases, infections, fever, anemia, hypotension, hypocalcemia, hyponatremia, azotemia, elevated liver enzymes, hyperamylasemia, hyperbilirubinemia and metabolic acidosis were predicting factors for delirium.

Spontaneous rupture of malarial spleen: two case reports and review of literature

Malaria has long been among the most common diseases in the southeast Anatolia region of Turkey. In 1992, 18676 cases were diagnosed in Turkey, and Diyarbakir city had the highest incidence (4168 cases), followed by SanliUrfa city (3578 cases). Malaria was especially common during 1994 and 1995, with 84345 and 82094 cases being diagnosed in these years, respectively. Spontaneous rupture of malarial spleen is rare. We saw two cases during 1998, which are reported herein. Both patients were male, and were receiving chloroquine treatment for an acute attack of malaria. One of the patients had developed abdominal pain and palpitations, followed by fainting. The other patient had abdominal pain and fever. Explorative laparotomy revealed an enlarged spleen in both patients. Splenectomy was performed in both patients. We have identified 15 episodes of spontaneous rupture of the spleen in the English language literature published since 1961. Because of increased travel to endemic areas and resistance to antimalarial drugs, malaria is a major medical problem that is becoming increasingly important to surgeons worldwide. Malaria is a particularly important problem in the southeast Anatolia region of Turkey. Prophylactic precautions should be taken by tourists who travel to this region, especially during the summer.

Looking at trauma and deaths: Diyarbakir city in Turkey

There were 329 trauma related deaths in Diyarbakir in 1997. Of these 226 were male (69%) and 103 were female (31%). The median age was 20 years old (range 1-82 years). Of the deaths, 30.5% were under 10, 51% were under 20 and 67% were under 30 years old. Two hundred and eleven deaths occurred in the hospital while 118 deaths occurred prehospital. Seventy-seven percent of hospital deaths (191) occurred in the first day. The most common cause of death was multiple injuries (151, 46%). Head injuries were the main reason for 128 deaths (46%). The most common mechanism of death was motor vehicle accident (131, 40%). The second was falls from a residential building (117, 33.7%).

Neonatal tetanus: a continuing challenge in the southeast of Turkey: risk factors, clinical features and prognostic factors

Neonatal tetanus (NT) still causes significant mortality in developing countries, although in 1989 WHO adopted the goal of eliminating the disease by 1995-2000. To characterize the regional characteristics, clinical charts of 55 neonates (42 males and 13 females) admitted to the Pediatric Infectious Diseases Ward of Dicle University Hospital, Diyarbakir, Turkey with the diagnosis of NT from 1991 to 1997 were reviewed. Mean age at admittance was 8.9+/-4.3 days with a range of 3-25 days. Mean period for the appearance of first symptoms was 5.8 days ranging between 1 and 21 days. Mean birth weight of the patients was 3369+/-560g. All patients were from rural areas and were delivered at home by untrained traditional birth attendants with no prior antenatal healthcare services. Razor blade (55%), scissors (27%), and knife (18%) were the instruments used to cut the cord in non-hygienic conditions. No mothers had prior vaccination with tetanus toxoid during their pregnancy. Spasticity (76%), lack of sucking (71%), trismus (60%), fever (49%), omphalitis (44%), irritability (24%), risus sardonicus (22%), and opithotonus (15%) were the most common presenting signs and symptoms. Age at admission < 7.5 days and symptoms of onset <4.9 days, risus sardonicus and opisthotonus were associated with fatal outcome. All patients were treated with human tetanus immunglobulin or equine tetanus antitoxin where available, antibiotic therapy by penicillin G (100.000 U/kg/day) and intravenous high dose diazepam (40 mg/kg/day). Overall mortality rate was 40% (22 cases), without any equipment for mechanical ventilation. Health education of mothers and birth attendants, promotion of hospital delivery and prenatal tetanus immunization of all pregnant women particularly in rural areas are recommended, if NT is to be prevented.
