Mental health,social functioning,and feelings of hatred and revenge of Kosovar Albanians one year after the war in Kosovo

A cross-sectional cluster sample survey was conducted in June 2000 in Kosovo to assess the prevalence of mental health problems associated with traumatic experiences, feelings of hatred and revenge, and the level of social functioning among Kosovar Albanians approximately 1 year after the end of the war. Findings of the second cross-sectional survey were compared with those from our 1999 mental health survey in Kosovo. Included in the survey were 1399 Kosovar Albanians aged 15 years or older living in 593 randomly selected households across Kosovo. Twenty-five percent of respondents reported PTSD symptoms, compared with 17.1% in 1999. The MOS-20 social functioning score improved to 69.8 from 29.5 in 1999. In the 2000 survey 54% of men felt hatred toward the Serbs, compared with 88.7% in 1999.     

Roux-en-Y gastrojejunostomy: indications,technique, results

61 gastrojejunostomies were constructed between 1981-1999 in 58 cases (43 cases were operated between 1991-1999). 30 cases have previously suffered various gastric operations; in 28 cases the Roux-en-Y was the first gastric operation (27 operated on between 1991-1999). Radiologic and endobioptic studies were routine for diagnostic and follow-up evaluation, but various scintigraphic studies were performed in selected cases. The surgical technique was tailored for each case, according to the preoperative strategy. The indications for surgery were the following: 19-reflux disease; 14-severe peptic disease (9-reccurence, 3-postbulbar lesion, 2-juxtacardial ulcer); 8-peptic disease associated to reflux disease; 8-gastric cancer; 8-various early or late complications after gastrectomy; 1-lymphocytic gastritis. There were 4 early reoperations and 3 deceased. In 3 cases late reintervention was mandatory (for Zollinger-Ellison syndrome, peptic ulcer secondary to gastrectomy for cancer, Roux-stasis syndrome) and the Roux pattern was preserved; in 2 cases the antireflux effect of the operation was lost after the reoperation.

Population-based study of short- and long-term survival from colorectal cancer in Denmark, 1977-1999

BACKGROUND: Survival rates for patients with colorectal cancer have been lower in Denmark than in other European countries. The aim of this study was to examine temporal trends in relative survival from colorectal cancer between 1977 and 1999. METHODS: All patients diagnosed with colorectal cancer between 1977 and 1999 were identified using the nationwide population-based Danish Cancer Registry. Patients were linked with the Danish Central Population Registry to obtain data on survival to December 2002, and to select ten population controls per patient. RESULTS: A total of 69 562 patients with colorectal cancer were identified, of whom 49.2 per cent were men. Six-month relative survival after diagnosis increased from 69.7 per cent in 1977-1982 to 77.7 per cent in 1995-1999. Five-year relative survival rates increased from 37.8 to 46.8 per cent respectively. Women had slightly higher 5-year relative survival than men throughout the study period. Rectal tumours were associated with better survival than colonic tumours until 2 years after diagnosis, after which tumour location had no impact on survival. CONCLUSION: Relative survival of patients with colorectal cancer has improved in Denmark between 1977 and 1999, most probably reflecting better management of the disease.     

Comparison of WHO 1973, WHO/ISUP 1998, WHO 1999 grade and combined scoring systems in evaluation of bladder carcinoma

OBJECTIVES: To compare WHO 1973, WHO/ISUP 1998 and WHO 1999 histologic grading systems, and also to evaluate the primary (most common) and secondary (second most common) patterns of cancer growth according to these three grading systems. MATERIAL AND METHODS: The study consisted of 87 bladder transurethral resections that were classified as grade 1, 2 and 3, and papillary urothelial neoplasm of low malignant potential (PUNLMP), low grade (LG) and high grade (HG) carcinoma considering WHO 1973 and WHO/ISUP, respectively. The WHO 1999 system was subdivided high grade into grades 2 and 3 (HG-2 and HG-3). For combined scoring, primary (most common) and secondary (second most common) grades according to extension were recorded for three grading systems. The number was repeated when only grade was seen in all extension of the tissue examined. A final combined score was obtained which ranged from 2 to 6 for the WHO 1973 and WHO/ISUP 1998 systems and from 2 to 8 for the WHO 1999 schema. The TNM system was used for the pathologic staging. RESULTS: When considering the pathological stage, there were statistical differences between the WHO 1973 grades (p=0.011 and p=0.000), and LG and HG carcinomas of WHO/ISUP 1998 (p=0.000) and also the WHO 1999 grades (p=0.010 and p=0.003), except PUNLMP. Regarding the combined scoring, significant differences were found between score 4 (2+2) and 5 (2+3) of WHO 1973 (p=0.014) and score 5 (LG+HG) and 6 (HG+HG) of WHO/ISUP 1998 (p=0.011). There was also a significant difference between scores 4 and 6, and 6 and 8 of the WHO 1999 combined scoring system (p=0.019 and p=0.019). WHO 1973, WHO/ISUP 1998 and WHO 1999 systems were positively correlated with the pathological stage (r(s)=0.30, r(s)=0.52 and r(s)=0.50, respectively), whereas there was weak association between the combined scoring systems and stage (r(s)=0.20, r(s)=0.18 and r(s)=0.19). Comparing these grading systems, the grade 2 of WHO 1973 was subdivided into LG and HG in WHO/ISUP 1998 and also LG-1and HG-2 in WHO 1999 systems. The group of HG carcinoma in WHO/ISUP 1998 which was subdivided into HG-2 and HG-3 in the WHO 1999 system was different statistically in relation to the stage. CONCLUSIONS: Our results revealed that the WHO 1999 system may be more useful to evaluate the bladder carcinoma histopathologically in comparison to the WHO 1973 and WHO/ISUP 1998 systems.

Renal polyamine excretion, tubular amino acid reabsorption and molecular genetics in cystinuria

Cystinuria is an autosomal recessive disorder of the tubular and intestinal resorption of cystine, ornithine, lysine and arginine leading to nephrolithiasis. Three cystinuria types can be distinguished by the mode of inheritance (true recessive or intermediate) and by the pattern of the intestinal amino acid transport. In the present study phenotypes were assessed by the urinary excretion of amino acids related to creatinine, the percentage tubular amino acid reabsorption and the urinary excretion of polyamines as a possible indicator of the intestinal transport defect. However, our thorough phenotyping did not reveal more than two cystinuria types. Genotypes were examined in linkage analyses and single-strand conformation polymorphism-based mutation identification. The SLC3A1 mutations M467T and T216M were disease causing in our homozygous patients of type I cystinuria. We can show the association of type I cystinuria with SLC3A1 and of non-type I cystinuria with a yet unidentified gene on chromosome 19q13.1. Our phenotype and genotype analyses provide evidence for only two types of cystinuria in the investigated patient cohort.

46,XY gonadal dysgenesis associated with congenital nephrotic syndrome and sepsis

The occurrence of nephrosis in the first 3 months of life is rare and is termed ’congenital nephrotic syndrome.’ The congenital nephrotic syndrome is a group of heterogeneous diseases with a clinical course that differs markedly from the childhood nephrotic syndrome. The coexistence of a congenital nephrotic syndrome and gonadal dysgenesis in a 46,XY karyotype with normal female external genitalia is extremely rare. Frequent severe infections are often seen in the Finnish type, but sepsis leading to death is rare in the neonatal onset of gonadal dysgenesis. This report describes an unusual case of complete XY gonadal dysgenesis in a 46,XY female neonate with the congenital nephrotic syndrome and overwhelming sepsis.

Physician supply, treatment, and amputation rates for peripheral arterial disease

OBJECTIVE: To test whether the availability of vascular surgeons and interventional radiologists in a region affects revascularization and amputation rates for patients with peripheral arterial disease (PAD). METHODS: We identified all patients with PAD in the Medicare claims database in 1994 and tracked their claims through 1999. We aggregated risk-adjusted data on the 143,202 patients who survived through 1999 by Hospital Referral Region and merged this data with information on local physician supply and other regional characteristics. Instrumental variables analysis was used to account for unobserved illness severity. Main outcome measures were risk-adjusted rates of lower extremity bypass surgery, angioplasty, and amputation by region. RESULTS: Increasing vascular surgeon supply in a region by approximately one standard deviation (.30/10,000 Medicare beneficiaries) is associated with a 0.9 percentage point increase in bypass surgery rates and a 1.6 percentage point reduction in amputation rates. We find weaker evidence that greater availability of interventional radiologists increases angioplasty rates and reduces amputation rates. Factors reflecting regional attractiveness, such as the rating of a region based on climate, recreation, crime, and other attributes, were strong independent predictors of the number of vascular surgeons and interventional radiologists in an area. CONCLUSIONS: Availability of specialists affects outcomes for PAD patients. Regional variability in specialists who treat PAD is influenced by factors other than regional medical needs. Policies aimed at increasing the supply of vascular surgeons and interventional radiologists and their provision of bypass surgery in underserved areas may help to reduce regional disparities in amputation.     

Fournier's gangrene: etiology, treatment, and complications.

Presented here are 23 patients with Fournier's gangrene who were treated between 1990 and 1999 in the departments of general surgery, urology, and plastic and reconstructive surgery. Patients were reviewed retrospectively and are discussed according to age, gender, bacteriology, etiology, treatment, and outcome in the light of the current literature.     

Trends in mortality and hospital admission rates for abdominal aortic aneurysm in England and Wales, 1979-1999

BACKGROUND: The aim of this study was to investigate trends in population-based mortality, hospital admission and case fatality rates for abdominal aortic aneurysm (AAA) from 1979 to 1999. METHODS: This was an analysis of routine statistics from 79 495 death certificates in England and Wales and 3217 hospital inpatient admissions in the Oxford Region. RESULTS: Mortality rates for all AAAs increased between 1979 and 1999 from 13 to 25 per million in women and from 80 to 115 per million in men. Admission rates increased in the same time interval from three to 22 admissions per million per year in women, and from 52 to 149 per million per year in men. Case fatality rates for all non-ruptured AAAs that were operated on decreased from 25.8 to 9.0 per cent and for all ruptured AAAs from 69.9 to 54.4 per cent. CONCLUSION: Mortality rates and hospital admission rates for AAA rose in men and even more so in women between 1979 and 1999. Perioperative mortality for ruptured AAA declined a little during the study but nonetheless was still very high at the end. This reinforces the importance of detecting and treating AAA before rupture occurs.     

Racial,ethnic, and socioeconomic inequities in amputation risk for patients with peripheral artery disease and diabetes

Peripheral artery disease and diabetes are highly prevalent diseases and the leading cause of limb loss. Despite advances in medical and surgical techniques, there are stark differences in delivery and outcomes of lower extremity amputation among populations when stratified by race, ethnicity, and socioeconomic status. We reviewed studies from the last 2 decades (1999–2022) to provide a comprehensive assessment of the current impact of disparities on the risk for, and management of, lower extremity amputation and offer action items that can optimize health outcomes.     

Psychological symptoms of Turkish children and adolescents after the 1999 earthquake: exposure, gender, location, and time duration

The authors describe their study of posttraumatic stress symptoms of children and adolescents after the 1999 earthquakes in Turkey. The rate of possible PTSD cases is also presented. The findings are reported as the results of two different studies. Location had a main effect on almost all of the dependent variables for both samples. The posttraumatic stress symptom scores for both groups significantly decreased 3 months after the initial assessment. The best predictors of the perceived posttraumatic stress symptoms for both children and adolescents were found to be perceived negative school performance and exposure.

Chronic kidney disease awareness, prevalence, and trends among U.S. adults, 1999 to 2000

The incidence of kidney failure treatment in the United States increased 57% from 1991 to 2000. Chronic kidney disease (CKD) prevalence was 11% among U.S. adults surveyed in 1988 to 1994. The objective of this study was to estimate awareness of CKD in the U.S. population during 1999 to 2000 and to determine whether the prevalence of CKD in the United States increased compared with 1988 to 1994. Analysis was conducted of nationally representative samples of noninstitutionalized adults, aged 20 yr and older, in two National Health and Nutrition Examination Surveys conducted in 1988 to 1994 (n = 15,488) and 1999 to 2000 (n = 4101) for prevalence +/- SE. Awareness of CKD is self-reported. Kidney function (GFR), kidney damage (microalbuminuria or greater), and stages of CKD (GFR and albuminuria) were estimated from calibrated serum creatinine, spot urine albumin to creatinine ratio (ACR), age, gender, and race. GFR was estimated using the simplified Modification of Diet in Renal Disease Study equation. Self-reported awareness of weak or failing kidneys in 1999 to 2000 was strongly associated with decreased kidney function and albuminuria but was low even in the presence of both conditions. Only 24.3 +/- 6.4% of patients at GFR 15 to 59 ml/min per 1.73 m(2) and albuminuria were aware of CKD compared with 1.1 +/- 0.3% at GFR of 90 ml/min per 1.73 m(2) or greater and no microalbuminuria. At moderately decreased kidney function (GFR 30 to 59 ml/min per 1.73 m(2)), awareness was much lower among women than men (2.9 +/- 1.6 versus 17.9 +/- 5.9%; P = 0.008). The prevalence of moderately or severely decreased kidney function (GFR 15 to 59 ml/min per 1.73 m(2)) remained stable over the past decade (4.4 +/- 0.3% in 1988 to 1994 and 3.8 +/- 0.4% in 1999 to 2000; P = 0.23). At the same time, the prevalence of albuminuria (ACR >/= 30 mg/g) in single spot urine increased from 8.2 +/- 0.4% to 10.1 +/- 0.7% (P = 0.01). Overall CKD prevalence was similar in both surveys (9% using ACR > 30 mg/g for persistent microalbuminuria; 11% in 1988 to 1994 and 12% in 1999 to 2000 using gender-specific ACR cutoffs). Despite a high prevalence, CKD awareness in the U.S. population is low. In contrast to the dramatic increase in treated kidney failure, overall CKD prevalence in the U.S. population has been relatively stable.
