Epidemiology and Treatment Options of Primary Biliary Cirrhosis

Primary biliary cirrhosis (PBC) is caused by an autoimmune inflammation of the small bile ducts. It results to destruction of bile ducts, accumulation of the bile in the liver, and cirrhosis. The prevalence and incidence of PBC is increasing in the Western world. The prevalence is highest in the USA (402 per million) and incidence in Scotland (49/million/year). Our aim was to assess the epidemiology of PBC in Finland. Patients for the epidemiological study were searched from the hospital discharge records from year 1988 to 1999.The prevalence rose from 103 to 180/million from 1988 to 1999, an annual increase of 5.1%. The incidence rose from 12 to 17 /million/year, an annual increase of 3.5%. The age at death increased markedly from 65 to 76 years. The risk of liver related deaths diminished over time. The treatment of PBC is based on Ursodeoxycholic acid (UDCA). During 20 years 50% of patients end up with cirrhosis. Our treatment option was to combine budesonide, a potent corticosteroid with a high first pass metabolism in the liver, to UDCA and evaluate the liver effects and systemic effects such as bone mass density (BMD) changes. Our aim was to find out if combination of laboratory tests would serve as a surrogate marker for PBC and help reducing the need for liver biopsy. Non-cirrhotic PBC patients were randomized to receive budesonide 6 mg/day combined to UDCA 15 mg /kg/day or UDCA alone for three years. The combination therapy with UDCA and budesonide was effective: stage improved 22%, fibrosis 25%, and inflammation 32%. In the UDCA group the changes were: 20% deterioriation in stage and 70% in fibrosis, but a 10% improvement in inflammation. BMD in femoral neck decreased by 3.6% in the combination group and by 1.9% in the UDCA group. The reductions in lumbar spine were 2.8% and 0.7%. Pharmacokinetics did not differ between the stages of PBC. HA, PIIINP, bile acids, and AST were significantly different within stages I-III and could differentiate the mild fibrosis (F0F1) from the moderate (F2F3). The combination of these individual markers (PBC-score) further improved the accuracy. The area under the ROC of the PBC score, using a cut of value 66, had a sensitivity of 81.4% and a specificity of 65.2% to classify the stage of PBC. The prevalence of PBC in Finland increases, which results from increasing incidence and improved survival. The combination of budesonide and UDCA improves liver histology compared to UDCA alone in non-cirrhotic stages of PBC. The treatment may reduce BMD. Hyaluronic acid, PIIINP, AST, and bile acids may serve as tools to monitor the treatment response in the early stages of PBC. The budesonide and UDCA combination therapy is an option for those patients who do not receive full response from UDCA and are still at the non-cirrhotic stage of PBC.

Depressive Disorders in Primary Health Care

The Vantaa Primary Care Depression Study (PC-VDS) is a naturalistic and prospective cohort study concerning primary care patients with depressive disorders. It forms a collaborative research project between the Department of Mental and Alcohol Research of the National Public Health Institute, and the Primary Health Care Organization of the City of Vantaa. The aim is to obtain a comprehensive view on clinically significant depression in primary care, and to compare depressive patients in primary care and in secondary level psychiatric care in terms of clinical characteristics. Consecutive patients (N=1111) in three primary care health centres were screened for depression with the PRIME-MD, and positive cases interviewed by telephone. Cases with current depressive symptoms were diagnosed face-to-face with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I/P). A cohort of 137 patients with unipolar depressive disorders, comprising all patients with at least two depressive symptoms and clinically significant distress or disability, was recruited. The Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II), medical records, rating scales, interview and a retrospective life-chart were used to obtain comprehensive cross-sectional and retrospective longitudinal information. For investigation of suicidal behaviour the Scale for Suicidal Ideation (SSI), patient records and the interview were used. The methodology was designed to be comparable to The Vantaa Depression Study (VDS) conducted in secondary level psychiatric care. Comparison of major depressive disorder (MDD) patients aged 20-59 from primary care in PC-VDS (N=79) was conducted with new psychiatric outpatients (N =223) and inpatients (N =46) in VDS. The PC-VDS cohort was prospectively followed up at 3, 6 and 18 months. Altogether 123 patients (90%) completed the follow-up. Duration of the index episode and the timing of relapses or recurrences were examined using a life-chart. The retrospective investigation revealed current MDD in most (66%), and lifetime MDD in nearly all (90%) cases of clinically significant depressive syndromes. Two thirds of the “subsyndromal” cases had a history of major depressive episode (MDE), although they were currently either in partial remission or a potential prodromal phase. Recurrences and chronicity were common. The picture of depression was complicated by Axis I co-morbidity in 59%, Axis II in 52% and chronic Axis III disorders in 47%; only 12% had no co-morbidity. Within their lifetimes, one third (37%) had seriously considered suicide, and one sixth (17%) had attempted it. Suicidal behaviour clustered in patients with moderate to severe MDD, co-morbidity with personality disorders, and a history of treatment in psychiatric care. The majority had received treatment for depression, but suicidal ideation had mostly remained unrecognised. The comparison of patients with MDD in primary care to those in psychiatric care revealed that the majority of suicidal or psychotic patients were receiving psychiatric treatment, and the patients with the most severe symptoms and functional limitations were hospitalized. In other clinical aspects, patients with MDD in primary care were surprisingly similar to psychiatric outpatients. Mental health contacts earlier in the current MDE were common among primary care patients. The 18-month prospective investigation with a life-chart methodology verified the chronic and recurrent nature of depression in primary care. Only one-quarter of patients with MDD achieved and maintained full remission during the follow-up, while another quarter failed to remit at all. The remaining patients suffered either from residual symptoms or recurrences. While severity of depression was the strongest predictor of recovery, presence of co-morbid substance use disorders, chronic medical illness and cluster C personality disorders all contributed to an adverse outcome. In clinical decision making, beside severity of depression and co-morbidity, history of previous MDD should not be ignored by primary care doctors while depression there is usually severe enough to indicate at least follow-up, and concerning those with residual symptoms, evaluation of their current treatment. Moreover, recognition of suicidal behaviour among depressed patients should also be improved. In order to improve outcome of depression in primary care, the often chronic and recurrent nature of depression should be taken into account in organizing the care. According to literature management programs of a chronic disease, with enhancement of the role of case managers and greater integration of primary and specialist care, have been successful. Optimum ways of allocating resources between treatment providers as well as within health centres should be found.

Probiotics and prebiotics in the primary prevention of allergic diseases

The rapid increase in allergic diseases in developed, high-income countries during recent decades is attributed to several changes in the environment such as urbanization and improved hygiene. This relative lack of microbial stimulation is connected to a delay in maturation of the infantile immune system and seems to predispose especially genetically prone infants to allergic diseases. Probiotics, which are live ingestible health-promoting microbes, may compensate for the lack of microbial stimulation of the developing gut immune system and may thus be beneficial in prevention of allergies. Prebiotics, which are indigestible nutrients by us, promote the growth and activity of a number of bacterial strains considered beneficial for the gut. In a large cohort of 1 223 infants at hereditary risk for allergies we studied in a double-blind placebo-controlled manner whether probiotics administered in early life prevent allergic diseases from developing. We also evaluated their safety and their effects on common childhood infections, vaccine antibody responses, and intestinal immune markers. Pregnant mothers used a mixture of four probiotic bacteria or a placebo, from their 36th week of gestation. Their infants received the same probiotics plus prebiotic galacto-oligosaccharides for 6 months. The 2-year follow-up consisted of clinical examinations and allergy tests, fecal and blood sampling, and regular questionnaires. Among the 925 infants participating in the 2-year follow-up the cumulative incidence of any allergic disease (food allergy, eczema, asthma, rhinitis) was comparable in the probiotic (32%) and the placebo (35%) group. However, eczema, which was the most common manifestation (88%) of all allergic diseases, occurred less frequently in the probiotic (26%) than in the placebo group (32%). The preventive effect was more pronounced against atopic (IgE-associated) eczema which, of all atopic diseases, accounted for 92%. The relative risk reduction of eczema was 26% and of atopic eczema 34%. To prevent one case of eczema, the number of mother-infant pairs needed to treat was 16. Probiotic treatment was safe without any undesirable outcome for neonatal morbidity, feeding-related behavior, serious adverse events, growth, or for vaccine-induced antibody responses. Fewer infants in the probiotic than in the placebo group received antibiotics during their first 6 months of life and thereafter to age 2 years suffered from fewer respiratory tract infections. As a novel finding, we discovered that high fecal immunoglobulin A (IgA) concentrations at age 6 months associated with reduced risk for atopic (IgE-associated) diseases by age 2 years. In conclusion, although feeding probiotics to high-risk newborn infants showed no preventive effect on the cumulative incidence of any allergic diseases by age 2, they apparently prevented eczema. This probiotic effect was more pronounced among IgE-sensitized infants. The treatment was safe and seemed to stimulate maturation of the immune system as indicated by increased resistance to respiratory infections and improved vaccine antibody responses.

Primary Dislocation of the Patella : A Clinical Study

A total of 177 patients with primary dislocation of the patella (PDP) were admitted to two trauma centers in Helsinki, Finland during 1991 to 1992. The inclusion criteria were: 1. Acute (≤14 days old) first-time lateral dislocation of the patella. 2. No previous knee operations or major knee injuries. 3. No ligament injuries to be repaired. 4. No osteochondral fractures requiring fixation. 50 patients were excluded. 30 of these excluded patients would have met the inclusion criteria, 19 patients received treatment by consultants not involved in the study, 7 refused to participate and 4 had an erroneous randomization. 127 patients including, 82 females, were then randomized to have either tailor-made operative procedure (group O) or conservative treatment (group C). The aftercare was similar for both groups. The mean age of the patients was 20 (9-47) years. All patients were subjected to analysis of trauma history (starting position and knee movement during the dislocation), examination under anesthesia (EUA) and arthroscopy. 70 patients (52 females) were randomized by their odd year of birth to operative group O and 57 patients (30 females) by their even year of birth to conservative group C. The diagnosis of PDP was based on locked dislocation in 68 patients, on dislocatability in EUA in 47 patients, and on subluxation in EUA combined with typical intra-articular lesions in 12 patients. In group O, 63 patients had exploration of the injuries on the medial side of the knee and tailor made reconstruction added with lateral release in 54 cases. The medial injury was operated by suturing in 39 patients, by duplication in 18 patients and by additional augmentation of the medial patellofemoral ligament (MPFL) with adductor magnus tenodesis in 6 patients. 7 patients, without locking in trauma history and only subluxation in EUA had only lateral release for realignment. In adductor magnus tenodesis the proximal end of the distal tendinous part was rerouted to the upper medial border of the patella. In the conservative group C, the treatment was adjusted to the extent of patellar displacement in EUA. Patients with dislocation in EUA had 3 weeks’ immobilization with the knee in slight flexion. Mobilization was started with a soft patellar stabilizing orthosis (PSO) used for additional three weeks. The patients with subluxation in EUA wore an orthosis for six weeks. The aftercare was similar in group O. The outcome was similar in both groups. After an average of 25 (20-45) months´ follow-up, the subjective result was better in group C in respect of the mean Hughston VAS knee score (87 for group O and 90 for group C, p=0.04, visual analog scale), but similar in terms of the patient’s own overall opinion and the mean Lysholm II knee score. Recurrent instability episodes occurred in 18 patients in group O and in 20 patients in group C. After an average of 7 (6-9) years´ follow-up, the groups did not show statistical difference either in respect of the patient’s own overall opinion, or the mean Hughston VAS and Kujala knee scores. The proportions of stable patellae was 25/70 (36%) in group O and 17/57 (30%) in group O (p=0.5). In a multivariate risk analysis, there was a correlation between low Kujala score (<90) as dependent parameter and female gender (OR: 3.5; 95% CI: 1.4-9.0), and loose body on primary radiographs (OR: 4.1; 95% CI: 1.2-15). Recurrent instability correlated with young age at the time of PDP (OR: 0.9; 95% CI: 0.8-1.0/year). Girls with open tibial apophysis had the worst prognosis for instability (88%; 95% CI: 77-98). The most common mechanisms in trauma history of the patients were movement to flexion from a straight start (78%) and movement to extension from a well-bent start (8%). Spontaneous relocation of the patella had taken place in 13/39 of girls, in 11/21 of boys, in 26/42 of women and in 17/24 of men with skeletal maturity of the tibia. The dislocation in EUA was non-rotating in 96/126 patients followed by outward rotating dislocation in 14/126 patients. Operative treatment policy in PDP is not recommended. Locking tendency of the patella in PDP depended on the skeletal maturation. Recurrence rate after PDP was higher than expected.

Primary polyestradiol phosphate versus orchiectomy for advanced prostate cancer : Studies on the efficacy, cardiovascular complications and prognostic factors

Paikallisesti levinnyttä (T3-4 M0) ja luustoon levinnyttä (T1-4 M1) eturauhassyöpää sairastaneet potilaat satunnaistettiin kirurgiseen kastraatioon (orkiektomia) tai lääkkeelliseen kastraatioon lihaksensisäisellä polyestradiolifosfaatilla (PEP) annoksella 240 mg/kk. Verrattiin hoitojen kliinistä tehoa sekä sydän- ja verisuonikomplikaatioita (SV-komplikaatioita). Verrattiin myös hoitoa edeltäviä plasman testosteroni (T) ja estradioli (E2) pitoisuuksia T3-4 M0 ja T1-4 M1 potilaiden välillä sekä selvitettiin potilaiden yleistilan vaikutusta näihin hormonitasoihin. Lopuksi luotiin T1-4 M1 potilaille eturauhassyövän aiheuttaman kuoleman ennusteellinen riskiluokittelu kolmeen riskiryhmään käyttämällä hoitoa edeltäviä ennustetekijöitä. Kliinisessä tehossa ei orkiektomian ja PEP-hoidon välillä todettu tilastollisesti merkitsevää eroa. Odotetusti T1-4 M1 potilaiden ennuste oli huonompi kuin T3-4 M0 potilaiden. T1-4 M1 potilailla ei ollut SV-kuolemissa hoitoryhmien välillä tilastollista eroa, mutta ei-tappavia SV-komplikaatioita oli PEP ryhmässä (5.9%) enemmän kuin orkiektomia ryhmässä (2.0%). T3-4 M0 potilailla PEP-hoitoon liittyi tilastollisesti merkitsevä SV-kuolleisuus riski orkiektomiaan verrattuna (p = 0.001). PEP ryhmässä 67% kuolemista oli akuutteja sydäninfarkteja. Tämä PEP hoitoon liittyvä sydäninfarktiriski (mukaan lukien myös ei-tappavat sydäninfarktit) oli merkitsevästi pienempi potilailla, joiden hoitoa edeltävä E2 taso oli vähintään 93 pmol/l (p = 0.022). E2 taso oli merkitsevästi matalampi T1-4 M1 potilailla (74.7 pmol/l) kuin T3-4 M0 potilailla (87.9 pmol/l), mutta vastaavaa eroa ei ollut T tasoissa. Sekä T3-4 M0 että T1-4 M1 potilailla yleistilan lasku osittain selitti yksilöllisen T ja E2 tasojen laskun. Eturauhassyövän aiheuttaman kuoleman riskiryhmäluokittelu (Rg) kolmeen ryhmään luotiin käyttämällä alkalista fosfataasia (AFOS), prostata spesifistä antigeenia (PSA), laskoa (La) ja potilaan ikää. Yksi riskipiste annettiin, jos AFOS > 180 U/l (tällä hetkellä käytössä olevalla menetelmällä AFOS > 83 U/l), PSA > 35 µg/l, La > 80 mm/h ja ikä < 60 vuotta. Lopuksi pisteet laskettiin yhteen. Muodostettiin seuraavat ryhmät: Rg-a (0 -1 riskipistettä), Rg-b (2 riskipistettä) ja Rg-c (3 – 4 riskipistettä). Eturauhassyövän aiheuttama kuoleman riski lisääntyi merkitsevästi siirryttäessä riskiryhmästä seuraavaan (p < 0.001). Rg-luokittelu oli kliinisesti käytännöllinen ja hyvä havaitsemaan huonon ennusteen potilaat.

Primary Fallopian tube carcinoma:occurrence, risk and prognostic factors

The aim of the study was to clarify the occurrence, and etiological and prognostic factors of primary fallopian tube carcinoma (PFTC). We studied the sociodemographic determinants of the incidence of PFTC in Finland and the role of chlamydial infections and human papillomavirus infections as risk factors for PFTC. Serum tumor markers were studied as prognostic factors for PFTC. We also evaluated selected reproductive factors (parity, sterilization and hysterectomy) as risk or protective factors of PFTC. The risks of second primary cancers after PFTC were also studied. The age-adjusted incidence of PFTC in Finland increased to 5.4 / 1,000,000 in 1993 97. The incidence rate was higher in the cities, but the relative rise was higher in rural areas. Women in the two highest social classes showed a 1.8 fold incidence compared with those in the lowest. Women in agriculture and those not working outside the home showed only half the PFTC incidence of those in higher socioeconomic occupations. Pretreatment serum concentrations of hCGβ, CA125 and TATI were evaluated as prognostic markers for PFTC. Elevated hCGβ values (above the 75th percentile, 3.5 pmol/L; OR 2.49, 95% CI 1.22 5.09), stage and histology were strong independent prognostic factors for PFTC. The effects of parity, sterilization and hysterectomy on the risk of PFTC were studied in a case control-study with 573 PFTC cases from the Finnish Cancer Registry. In multivariate analysis parity was the only significant protective factor as regards PFTC, with increasing protection associated with increasing number of deliveries. In univariate analysis sterilization gave borderline protection against PFTC and the protective effect increased with time since the operation. In multivariate analysis the protection did not reach statistical significance. Chlamydial and human papillomavirus (HPV) infections were studied in two separate seroepidemiological case-control studies with 78 PFTC patients. The incidence of women with positive HPV or chlamydial serology was the same in PFTC patients and in the control group and was not found to be a risk factor for PFTC. Finally, the possible risk of a second primary cancer after diagnosis and treatment of PFTC in a cohort of 2084 cases from 13 cancer registries followed for second primary cancers within the period 1943 2000 was studied. In PFTC patients, second primary cancers were 36% more common than expected (SIR 1.36, 95% CI 1.13 1.63). In conclusion, the incidence of PFTC has increased in Finland, especially in higher social classes and among those in certain occupations. Elevated serum hCGβ reflect a worsened prognosis. Parity is a clear protective factor, as is previous sterilization. After PFTC there is a risk of second primary cancers, especially colorectal, breast, lung and bladder cancers and non-lymphoid leukemia. The excess of colorectal and breast cancers after PFTC may indicate common effects of earlier treatments, or they could reflect common effects of lifestyle or genetic, immunological or environmental background.

Exploring primary school sex education in Greece : policies and praxis

This study examines how sex education is currently developed and implemented in Greek primary schools. The four publications that comprise it explore the following themes: (1) the position and visibility of sex education as one of the topics for health education programme development; (2) the inhibiting and enhancing factors in the development and implementation of primary school sex education programmes; (3) how issues of sex, sexuality, the human body and romantic relationships are visually and textually represented in primary school textbooks; (4) the impact of sex education on teachers and pupils; and (5) teachers experiences as practitioners who deal with sexuality- related issues at school. -- The research was based on conducting multiple sub-studies using a mixed-methods approach. Specifically, qualitative and quantitative data were collected and analysed. The initial quantitative data that had been obtained by questionnaire was followed by the collection and analysis of qualitative data. The qualitative data were acquired by way of examining one particular case, various texts, interviews with teachers and self-reflective material. The results of the sub-studies are presented in a more detailed manner in the study s four publications. -- In general, the sub-studies found that sex education as an educational activity occupies a marginal place within the instructional practices of Greek primary school teachers, since the subject is hardly mentioned in classroom material, such as textbooks. However, engaging in the provision of sex education programmes can become a meaningful and rewarding experience for many teachers as well as pupils and their families. Further, teachers classroom experiences pointed to school settings as sexualized environments. These contextual factors and conditions nevertheless affected teachers practices and perceptions on a personal and professional level.Health indicators in Greece provide a picture of a population that faces various sexual health related problems. However, as many studies (including this work) indicate, sex education programmes that meet specific standards can have a positive impact on students overall health and well-being. Sex education teaching has always been a controversial issue. Its successful implementation in Greece demands knowledgeable educators and responsible policy-makers. The findings of this study suggest that the content of Greek primary school textbooks needs to be revised in order to include texts and pictures that deal with the human body and human sexuality, encourage pupils to become involved in designing the content and methods of programmes and give teachers the opportunity to reflect on and discuss their experiences.

Children’s Relationship to Plants among Primary School Children in Finland

There is considerable evidence that children in modern society are losing
their contact with nature and, more precisely, with green plants. Is this also the case in Finland, a northern country famous for its forests and wild nature? This study examines the relationship of 9- to 10-year-old Finnish schoolchildren with the green environment and plants. The data were gathered by a questionnaire
comprising structured and open-ended questions. The focus of the research was on two comparisons: first, on the nature and child relationship in rural and urban neighborhoods and, second, among boys and girls. Participants in the study amounted to a total of 76 children, 42 in the Helsinki suburb area and 34 in Paltamo. The results suggested that the children in rural surroundings had closer contact with nature than their urban associates. For example, the children of Paltamo reported to know the trees better, and considered human beings to be part of nature more often (100% vs. 76% of the pupils in Helsinki, P = 0,003). Similarly, the results showed that girls in the study (N = 48) were more interested in plants than boys (N = 28). For the girls, the beauty and joy of plants was important, whereas the boys appreciated plants as the source of life. After the pre-questioning, the children of Helsinki participated in an in-class horticultural intervention and 10 days later, answered a similar questionnaire again. The results of the open-ended questions revealed that equally to children in other Western countries, Finnish children may also be in danger of losing their direct contact with the natural environment. It was common to pass free time in organized sports such as hockey or football (boys), or by just walking and talking with friends (girls). Rural children told that they still built huts, pick berries, and climb trees, whereas urban children played in parks and city groves. The results suggest that it is essential to research
further the children’s own experiences if we are to understand, and subsequently, to enhance, the crucial role of the green environment in their lives. Horticultural interventions can be effective starting points to add to children’s knowledge, affection, and interest toward greenery, but it is highly recommended that they take place outdoors rather than indoors.
