Immunological parameters in girls with Turner syndrome

Disturbances in the immune system has been described in Turner syndrome, with an association to low levels of IgG and IgM and decreased levels of T- and B-lymphocytes. Also different autoimmune diseases have been connected to Turner syndrome (45, X), thyroiditis being the most common.     

Rehabilitation of Bells’ palsy from a multi-team perspective

Conclusions Defectively healed facial paralysis causes difficulties to talk and eat, involuntary spasms (synkinesis), and cosmetic deformities which can give rise both to severe psychological and physical trauma. A team consisting of Ear-Nose-Throat specialists, Plastic surgeons and Physiotherapists can offer better care, treatment and outcome for patients suffering from Bells' palsy.

Objectives Patients suffering from Bells' palsy from all ENT hospitals in Sweden and the University Hospital in Helsinki has been included.

Methods Results have been drawn and statistically processed for different outcomes from a prospective, double blind cross over study. Results from a pilot surgical study and therapeutic results from physiotherapy studies have been included. Ideas concerning different kinds of surgery will be reviewed and the role of physiotherapy discussed.

Results According to common results, treatment with Prednisolone enhances the recovery rate and should, if possible, be used early in the course. Sunnybrook grading at 1 month after onset most accurately predicts non-recovery at 12 months in Bells’ palsy and a risk factor curve will be presented in order to predict outcome and selection of patients for undergoing facial surgery. This report is focusing on how to handle patients with Bells’ palsy from a multi-rehabilitation team point of view, and what will be recommended to provide these patients with the best clinical and surgical help.     

Iron mediates production of a neutrophil chemoattractant by rat hepatocytes metabolizing ethanol.

Ethanol metabolism in hepatocytes is accompanied by release of a potent lipid chemoattractant for neutrophils. Production of the factor may initiate the inflammation associated with alcoholic hepatitis. In previous studies with a cytosol system from liver, production was blocked by iron chelators as well as by catalase and superoxide dismutase, suggesting the involvement of oxyradicals in formation of the chemoattractant. These studies have examined the role of iron in intact hepatocytes using cells from rats fed an iron-deficient diet, a control diet or a diet containing 3% carbonyl iron. The iron content averaged 1.4 nmol/mg protein in iron-deficient cells, 6.3 in controls and 135.3 in iron-loaded cells. Hepatocytes from all groups were established in primary culture and incubated with ethanol (10 mM); the medium was assayed for chemoattractant activity for human neutrophils. Cultures from chow-fed or iron-loaded animals produced chemoattractant as previously reported. By contrast, chemoattractant production was undetectable in the iron-deficient cultures. Addition of ferric citrate (10 microM) restored chemoattractant production while increasing cellular iron in the deficient cells less than 50% (to 2.3 nmol/mg protein). Addition of desferrioxamine mesylate to cultures of iron-loaded cells ablated chemoattractant production. The data provide evidence for the importance of hepatocellular iron in production of this alcohol-related lipid chemoattractant and suggest that a small intracellular pool of "free" iron plays a critical role.     

Self-reported fertility in long-term survivors of acute myeloid leukemia

Acute myeloid leukemia (AML) survival rates in younger patients have improved considerably since the 1970s. In order to evaluate the impact of AML and its treatment on fertility and family situation in adult long-term survivors, we used the Swedish population-based registries to identify 161 adult patients diagnosed with AML within the Leukemia Group of Middle Sweden (LGMS) 1973–2003, who survived for more than 5 years and were alive in 2010. Ninety-eight patients (61 %) completed a questionnaire including items on reproductive concerns, family situation, and infertility-related distress. After excluding women >45 years and/or postmenopausal women and men >55 years, 22 women and 38 men were included in the final analysis. Nine of the women (41 %) tried to conceive after treatment, but only three succeeded. Five (83 %) of the unwillingly childless women reported “a moderate” or “a lot” of distress caused by this. Among men in the same age group, all six who wanted children after treatment succeeded. None of the men 46–55 years old cryopreserved their sperm or tried to father a child. Among patients who wanted children after AML treatment, 46 % of the women and 40 % of the younger men reported that they were not, or not fully, informed about fertility-related issues. In contrast, among men 46–55 years, none reported they would have wanted more information. Infertility among young female AML survivors thus remains an important clinical issue, and there is a need for improved clinical counseling and education in this area.
