Cognitive and neuroradiological findings in myotonic dystrophy.

Cognitive functions were investigated in 37 patients with myotonic dystrophy (MD) and correlated with clinical and neuroradiological variables. The whole cognitive performance was at a low-average level; in about 1/3 of the subjects, in fact, the scores at the neuropsychological tests were below the normal range. There was a consistent trend for patients with inheritance on maternal side to perform worse on Wechsler verbal score and to present cerebral atrophy. In 7 out of 12 subjects focal white matter lesions were found at nuclear magnetic resonance. The significance of these findings and its relation to cognitive performance are discussed.     

Is the Evaluation of the Global Quality of Life Determined by Emotional Status?

The present study investigated relationships between global QOL perceptions and well-being dimensions. Especially our goal was to evaluate the impact of generally recognised four broad dimensions of QOL (physical, functional, social and emotional well-being) on global QOL perceptions, additionally person's satisfaction with life achievements and economical situation were measured as well as social demographic variables. The subjects were a representative sample of Finns (n = 4613, from 25 to 65 years) of the FINRISK-97 study. Correlation coefficients and models of hierarchical regression indicated that physical, functional and social well-being as well as sociodemographic factors and satisfaction with life achievements are important factors of global QOL perceptions both among males and females. However percentages of variances explained with these measures were only moderately high, ranging from 1 to 10%. After measures of emotional well-being were entered into the models of hierarchical analyses of regression, variances explained grew dramatically over 20%. The results of the study indicated that global QOL judgements are likely to be based on current emotional state.     

Fracture repair during external fixation: Torsion tests of rabbit osteotomies

Bone repair was studied in the rabbit tibiofibular bone after a midshaft transverse osteotomy stabilized by external fixation and heavy compression. Both subendosteal and subperiosteal callus formation with concomitant contact healing were observed within 3 weeks, and were further succeeded by subendosteal resorption and increased porosis resulting in atrophy of the cortical bone. Subjected to the torsion test, the bones exhibited restoration of strength within 3 weeks, with maximal energy absorption and elasticity at 6 weeks. The failure of the osteotomy in the torsion test, with radiographic visibility of the osteotomy, characterized the soft-tissue type of behavior of the bones. Hard-tissue like behaviour of the bones with resistance to torsion at the osteotomy site and radiographic obliteration of the osteotomy line occurred by 12 weeks, indicating complete union of the osteotomy. Our experiments demonstrate that elastic external fixation is preferable to the rigid compression plate.     

Extraperitoneal endometriosis: a diagnosis to be considered

Summary BACKGROUND: Endometriosis is a relatively common pathology in women of childbearing age and of low parity but rarely shows extraperitoneal involvement. The main aim of this paper is to raise the attention of specialists to the necessity of carrying out penetrating diagnosis of nonspecific extraperitoneal masses occurring in women of reproductive age. METHODS: We performed a retrospective review of six patients diagnosed with extraperitoneal endometriosis who were treated at the Vega Baja University Hospital (Spain) during the last 5 years. RESULTS: Surgical treatment had positive results in five patients. The preoperative diagnosis was correctly made in only two patients. The accurate aetiology of endometriosis remains unknown and diagnosis is based on clinical and cytopathological findings. CONCLUSIONS: Surgical treatment of extraperitoneal endometriosis is recommended. However, postoperative follow-up is obligatory and hormonal suppressive therapy may be necessary. Medical treatment with gestagens, Danazol, or agonists of the gonadotropin-releasing hormone are ineffective in endometriomas which are bigger than 2 cm.      

Operative versus closed treatment of primary dislocation of the patella Similar 2-year results in 125 randomized patients

To assess whether initial surgery is beneficial for patients with primary dislocation of the patella, we carried out a prospective randomized study. Knee stability was examined under anesthesia, and associated injuries were excluded by diagnostic arthroscopy. 55 patients then had closed treatment and 70 patients were operated on with individually adjusted proximal realignment procedures.

Surgery gave no benefit based on 2 years of follow-up. The subjective result was better in the non-operative group in respect of mean Houghston VAS knee score (closed 90, operative 87), but similar in terms of the patient's own overall opinion and mean Lysholm II knee score. Recurrent instability episodes (redislocation or recurrent subluxation) occurred in 20 nonoperated and in 18 operated patients. Of these, 15 and 12, respectively, then suffered redislo-cations. Function was better after closed treatment. Serious complications occurred after surgery in 4 patients.

In conclusion, the recurrence of patellar dislocation may be more frequent than reported, whatever the form of treatment. Routine operative management cannot be recommended for primary dislocation of the patella.     

Adolescent suicides with adjustment disorders or no psychiatric diagnosis

Detailed characteristics of adolescent suicides (aged 13–19 years) with adjustment disorders (AD) (N=11) or no psychiatric diagnosis (N=3) in a nationwide adolescent suicide population (N=53) from Finland are presented. The data were collected in a psychological autopsy study of all suicides in Finland (N=1397) during a 12-month period in 1987–1988. Data collection included thorough interviews with the victims' family members and professionals, and information from official records. All the suicides with AD or no diagnosis were males. Most of these victims used highly lethal suicide methods. Previous psychiatric treatment and previous suicide attempts were rare. They were seldom under the influence of alcohol when committing suicide. The process leading to suicide seemed to be of relatively short duration. According to informant reports, withdrawn or narcissistic individual characteristics predominated in many cases. Psychosocial stressors preceding suicide often involved interpersonal losses or conflicts. Talking of suicidal intentions prior to the act was common, indicating the need to take seriously all adolescents' expressions of intended suicide, even in the absence of explicit psychopathology.

Zusammenfassung Es werden detaiilierte Beschreibungen von Selbst-morden im Jugendalter, verbunden mit Anpassungsstörungen (N=11) oder keiner psychiatrischen Diagnose (N=3) vorgestellt. Diese stammten aus der Gesamtheit aller jugendlichen Selbstmörder (N=53) aus Finnland. Die Daten wurden in einer psychologischen Obduktionsstudie aller Selbstmörder Finnlands (N=1397) während eines einjährigen Zeitraumes zwischen 1987 und 1988 gesammelt. Die Datenerhebung umfaßte ausgiebige Interviews mit den Familienmitgliedern, beteiligten Fachkräften und Informationen von offizieller Seite. Die Selbstmörder mit Anpassungstörungen oder keiner Diagnose waren alle männlich. Die meisten dieser Opfer benützten sehr letale Suizidmethoden. Vorangegangene psychiatrische Behandlungen und Selbstmordversuche waren selten. Sie standen nur selten unter dem Enfluß von Alkohol, als der Selbstmord vollzogen wurde. Der Prozeß, der zu dem Suizid führte, schien von relativ kurzer Dauer zu sein. Entsprechend den Angaben der Informanden prädominierten in vielen Fällen zurückgezogene oder narzißtische Persönlichkeitsmerkmale. Psychosoziale Stressoren, die dem Suizid vorangingen, umfaßten interpersonelle Verluste oder Konflikte. Häufig wurde über die Suizidabsichten vor der Tat gesprochen. Dies verdeutlicht die Notwendigkeit, alle Suizidäußerungen von Jugendlichen ernstzunehmen, selbst dann, wenn eine explizite Psychopathologie fehlt.

Résumé Les caractéristiques détaillées de suicides d'adolescents (âgés de 13 à 19 ans) avec troubles avec l'adaptation (AD) (N=11) ou l'absence de diagnostic psychiatrique (N=3) sur une population de suicides d'adolescents s'étendant sur l'ensemble du pays (N=53), la Finlande sont présentées. Les faits ont été collectés dans le cadre d'une étude d'autopsie psychologique de tous les suicides en Finlande (N=1397) pendant une période de 12 mois 1987–1988. Le recueil des faits incluait des interviews avec les membres de la famille des victimes et les professionels ainsi que les informations provenant de documents officiels. Tous les suicides avec un trouble de l'adaptation ou sans diagnostic étaient masculins. La plupart de ces victimes utilisait des méthodes hautement mortelles. Les traitements psychiatriques précédents et les tentatives précédentes de suicides étaient rares. Ils étaient rarement sous l'influence de l'alcool quand ils ont commis les suicides. Le processus conduisant au suicide semblait être de durée relativement brève. Selon les rapports d'information, une attitude de retrait ou des caractéristiques individuelles de retrait prédominaient dans la majorité des cas. Les facteurs de stress psycho-sociaux précédent le suicide impliquaient souvent des pertes inter-personnelles ou des conflits. Parler du désir du suicide devant le passage à l'acte était habituel indiquant la nécessité de prendre au sérieux tous les adolescents exprimant le désir de suicide, même en l'absence d'une psychopathologie explicite.

     

Evidence of tendinitis provoked by fluoroquinolone treatment: a case-control study.

OBJECTIVE: To investigate the association between the use of fluoroquinolone agents and the risk of tendinitis in a large population-based case-control study. METHODS: The study was performed by linking automated health databases from the Region of Lombardia, Italy. Cases were patients aged > or =18 years who had a hospital discharge diagnosis of non-traumatic tendinitis in 2002-3. For each case, up to five controls were randomly selected among those eligible for inclusion in the study. A conditional logistic regression model was used to estimate the odds ratio of tendinitis associated with the current, recent and past use of fluoroquinolones. Odds ratios were adjusted for exposure to other antibacterials and other drugs. RESULTS: 22,194 cases and 104,906 controls met the inclusion criteria. Current use of fluoroquinolones significantly increased the risk of tendon disorders as a whole (odds ratio [OR] = 1.7; 95% CI 1.4, 2.0), tendon rupture (OR = 1.3; 95% CI 1.0, 1.8) and rupture of the Achilles' tendon (OR = 4.1; 95% CI 1.8, 9.6). Concomitant use of corticosteroids and fluoroquinolones increased the risk of both tendon rupture (OR = 3.1; 95% CI 1.5, 6.3) and rupture of the Achilles' tendon (OR = 43.2; 95% CI 5.5, 341.1). DISCUSSION: Evidence that exposure to fluoroquinolones is associated with the sudden occurrence of tendinitis is supported by this large population-based study. We can estimate that a single case of rupture of the Achilles' tendon would occur for every 5958 persons treated with fluoroquinolones (95% CI 2148, 23,085). The corresponding number needed to harm is 979 (95% CI 122, 9172) for patients who concomitantly use corticosteroids and 1638 (95% CI 351, 8843) for those aged >60 years. CONCLUSION: Clinicians should be aware of this adverse effect, and the increased risk for fluoroquinolone-associated tendinitis in elderly patients with corticosteroid use must be considered when these agents are prescribed.
