Rikottu hiljaisuus : Intialaisten sanomalehtien normista poikkeavia seksuaalisuuksia ja sukupuolia käsittelevät artikkelit heteromatriisin horjuttajina ja tabun uudelleenjärjestäjinä

Tutkielmassa tarkastellaan niitä tapoja, joilla intialaisissa englanninkielisissä sanomalehdissä käsitellään normista poikkeavia seksuaalisuuksia ja sukupuolia. Aineistona ovat vuosina 2003-2006 seuraavissa lehdissä ilmestyneet kirjoitukset: The Hindu, The Telegraph, Deccan Herald ja The Times of India kaupunkiliitteineen. Lisäksi aineistoon kuuluu yksi artikkeli The Statesman -lehdestä. Aineisto on jaettu kuuteen aiheryhmään: 1. Intian rikoslain 377. pykälä ja homoseksuaalisuuden dekriminalisointi, 2. hijrat, 3. Pushkin Chandran murha, 4. parisuhde, perhe ja avioliitto, 5. elokuvat ja lesbous, 6. homojen elämää. Ryhmien ulkopuolelle jää kuusi artikkelia, joita analysoidaan erikseen. Tutkielman lähtökohtana ja kysymyksenasettelun taustalla vaikuttaa queer-teoria. Tähän liittyy ajatus, ettei ole mitään muuttumatonta, olemuksellista sukupuolta, vaan sukupuoli on kulttuurista fiktiota, joka syntyy toiston ja tavoittamattoman ideaalin jäljittelyn kautta. Tutkielmassa tarkastellaan heteroseksuaalista matriisia - sitä kulttuuristen ymmärrysten verkkoa, jossa tietyt ruumiit, sukupuolet ja halut luonnollistuvat - Mary Douglasin kulttuurijärjestelmiä ja saastumista käsittelevien teorioiden sekä tabun käsitteen avulla. Aineistoa analysoidaan retoriseen diskurssianalyysiin tukeutuen. Analyysissa keskitytään artikkeleiden kielenkäyttöön ymmärrettäviksi tarkoitettuina argumentteina ja huomioidaan samalla rivien välistä luettavat merkitykset. Artikkeleita, joista suurin osa puolustaa homoseksuaalisuuden dekriminalisointia, tarkastellaan tabun uudelleenjärjestäjinä ja heteroseksuaalisen matriisin huojuttajina: ne pyrkivät homoseksuaalisuuden tabuun liittyvän hiljaisuuden rikkomisella kyseenalaistamaan vallitsevan järjestyksen, jossa vain heteroseksuaaliset halut hyväksytään. Toisaalta ne pyrkivät luomaan uudenlaisen järjestyksen, jonka katveisiin myös jää sopimatonta materiaalia. Silmiinpistävin uuteen järjestykseen sopimaton ihmisryhmä ovat hijrat, joilla on entisessä järjestelmässä ollut määrätty paikkansa järjestelmää ylläpitävänä anomaliana. Hijroja tarkastellaan artikkeleissa sekä osana transsukupuolisuuden teemaa että intialaista mytologiaa. Pyrkiessään muokkaamaan yleisön asenteita suvaitsevammiksi seksuaalista ja sukupuolista monimuotoisuutta kohtaan artikkelit käyttävät monenlaisia retorisia keinoja. Seksuaali- ja sukupuolivähemmistöjen edustajat pyritään esittämään niin sankareina kuin uhreinakin. Seksuaalivähemmistöihin pyritään liittämään luonnollisuuden ja normaaliuden määreet. Hijrojen kohdalla muistutetaan heidänkin olevan ihmisiä. Suvaitsevaisuuden puolesta käytetään argumenttina niin intialaista perinnettä kuin modernia länsimaista kulttuuria. Nyky-Intian homofobiasta ja kolonialistisesta perinnöstä sen sijaan pyritään erottautumaan.

Finnish cattle as reservoir of Campylobacter spp.

The reported incidence of human campylobacteriosis in Finland is higher than in most other European countries. A high annual percentage of sporadic infections is of foreign origin, although a notable proportion of summer infections is domestically acquired. While chickens appear to be a major source of campylobacters for humans in most countries, the prevalence of campylobacters is very low in chicken slaughter batches in Finland. Data on other potential animal reservoirs of human pathogenic campylobacters in Finland are scarce. Consequently, this study aimed to investigate the status of Finnish cattle as a potential source of thermophilic Campylobacter spp. and antibiotic-resistant Campylobacter jejuni for human sporadic campylobacter infections of domestic origin. A survey of the prevalence of thermophilic Campylobacter spp. in Finnish cattle studied bovine rectal faecal samples (n=952) and carcass surface samples (n=948) from twelve Finnish slaughterhouses from January to December 2003. The total prevalence of Campylobacter spp. in faecal samples was 31.1%, and in carcass samples 3.5%. Campylobacter jejuni, the most common species, was present in 19.5% of faecal samples and in 3.1% of carcasses. In addition to thermophilic Campylobacter spp., C. hyointestinalis ssp. hyointestinalis was present in bovine samples. The prevalence of campylobacters was higher among beef cattle than among dairy cattle. Using the enrichment method, the number of positive faecal samples was 7.5 times higher than that obtained by direct plating. The predominant serotypes of faecal C. jejuni, determined by serotyping with a set of 25 commercial antisera for heat-stable antigens (Penner), were Pen2 and Pen4-complex, which covered 52% of the samples. Genotyping with pulsed-field gel electrophoresis (PFGE) using SmaI restriction yielded a high diversity of C. jejuni subtypes in cattle. Determining the minimum inhibitory concentrations of ampicillin, enrofloxacin, erythromycin, gentamicin, nalidixic acid, and oxytetracycline among bovine C. jejuni isolates using a commercial broth microdilution method yielded 9% of isolates resistant to at least one of the antimicrobials examined. No multiresistant isolates were found among the bovine C. jejuni strains. The study of the shedding patterns of Campylobacter spp. among three Finnish dairy cattle herds included the examination of fresh faecal samples and tank milk samples taken five times, as well as samples from drinking troughs taken once during the one-year study. The semiquantitative enrichment method detected C. jejuni in 169 of the 340 faecal samples, mostly at low levels. In addition, C. jejuni was present in one drinking trough sample. The prevalence between herds and sampling occasions varied widely. PFGE, using SmaI as restriction enzyme, identified only a few subtypes in each herd. In two 2 of the herds, two subtypes persisted throughout the sampling. Individual animals presented various shedding patterns during the study. Comparison of C. jejuni isolates from humans, chickens and cattle included the design of primers for four new genetic markers selected from completely sequenced C. jejuni genomes 81-176, RM1221 and NCTC 11168, and the PCR examination of domestic human isolates from southern Finland in 1996, 2002 and 2003 (n=309), chicken isolates from 2003, 2006 and 2007 (n=205), and bovine isolates from 2003 (n=131). The results revealed that bovine isolates differed significantly from human and chicken isolates. In particular, the - glutamyl transpeptidase gene was uncommon among bovine isolates. The PFGE genotyping of C. jejuni isolates, using SmaI and KpnI restriction enzymes, included a geographically representative collection of isolates from domestic sporadic human infections, chicken slaughter batches, and cattle faeces and carcasses during the seasonal peak of campylobacteriosis in the summer of 2003. The study determined that 55.4% of human isolates were indistinguishable from those of chickens and cattle. Temporal association between isolates from humans and chickens was possible in 31.4% of human infections. Approximately 19% of the human infections may have been associated with cattle. However, isolates from bovine carcasses and human cases represented different PFGE subtypes. In conclusion, this study suggests that Finnish cattle is a notable reservoir of C. jejuni, the most important Campylobacter sp. in human enteric infections. Although the concentration of these organisms in bovine faeces appeared to be low, excretion can be persistent. The genetic diversity and presence or absence of marker genes support previous suggestions of host-adapted C. jejuni strains, and may indicate variations in virulence between strains from different hosts. In addition to chickens, Finnish cattle appeared to be an important reservoir and possible source of C. jejuni in domestic sporadic human infections. However, sources of campylobacters may differ between rural and urban areas in Finland, and in general, the transmission of C. jejuni of bovine origin probably occurs via other routes than food.

Magnetic resonance imaging and ultrasonography in brachial plexus birth injury

Brachial plexus birth injury (BPBI) is caused by stretching, tearing or avulsion of the C5-C8 or Th1 nerve roots during delivery. Foetal-maternal disproportion is the main reason for BPBI. The goal of this study was to find out the incidence of posterior subluxation of the humeral head during first year of life in BPBI and optimal timing of the ultrasonographic screening of the glenohumeral joint. The glenohumeral congruity and posterior subluxation of the humeral head associated to muscle atrophy were assessed and surgical treatment of the shoulder girdle as well as muscle changes in elbow flexion contracture were evaluated. The prospective, population based part of the study included all neonates born in Helsinki area during years 2003-2006. Patients with BPBI sent to the Hospital for Children and Adolescents because of decreased external rotation, internal rotation contracture or deformation of the glenohumeral joint as well as patients with elbow flexion contracture were also included in this prospective study. The incidence of BPBI was calculated to be 3.1/1000 newborns in Helsinki area. About 80% of the patients with BPBI recover totally during the follow-up within the first year of life. Permanent plexus injury at the age of one year was noted in 20% of the patients (0.64/1000 newborns). Muscle imbalance resulted in sonographically detected posterior subluxation in one third of the patients with permanent BPBI. If muscle imbalance and posterior subluxation are left untreated bony deformities will develop. All patients with internal rotation contracture of the glenohumeral joint presented muscle atrophy of the rotator cuff muscles. Especially subscapular and infraspinous muscles were affected. A correlation was found particularly between greatest thickness of subscapular muscle and subluxation of the humeral head, degree of glenoid retroversion, as well as amount of internal rotation contracture. Supinator muscle atrophy was evident among all the studied patients with elbow flexion contracture. Brachial muscle pathology seemed to be an important factor for elbow flexion contracture in BPBI. Residual dysfunction of the upper extremity may require operative treatment such as tendon lengthening, tendon transfers, relocation of the humeral head or osteotomy of the humerus. Relocation of the humeral head improved the glenohumeral congruency among patients under 5 years of age. Functional improvement without remodeling of the glenohumeral joint was achieved by other reconstructive procedures. In conclusion: Shoulder screening by US should be done to all patients with permanent BPBI at the age of 3 and 6 months. Especially atrophy of the subscapular muscle correlates with glenohumeral deformity and posterior subluxation of the humeral head, which has not been reported in previous studies. Permanent muscle changes are the main reason for diminished range of motion of the elbow and forearm. Relocation of the humeral head, when needed, should be performed under the age of 5 years.
