Individualized quality of life of severely affected multiple sclerosis patients: practicability and value in comparison with standard inventories.

PURPOSE: Individualized quality of life (QoL) measures differ from traditional inventories in that QoL domains/weights are not predetermined, but identified by the individual. We assessed practicability of the Schedule for the Evaluation of Individual QoL-Direct Weighting (SEIQoL-DW) interview in severely affected multiple sclerosis (MS) patients; the key QoL dimensions identified; and the correlation of the SEIQoL-DW index score with standard patient-reported outcome measures (PROMs). METHODS: Participants were people with severe MS who performed the baseline visit of the PeNSAMI trial (ISRCTN73082124). The SEIQoL-DW was administered at the patient's home by a trained examiner. Patients then received the following PROMs: the Core-Palliative care Outcome Scale (Core-POS), the Palliative care Outcome Scale-Symptoms-MS (POS-S-MS), the European Quality of Life Five Dimensions-3L (EQ-5D-3L), and the Hospital Anxiety and Depression Scale (HADS). RESULTS: Of 59 enrolled patients, 11 (19 %) did not receive the SEIQoL-DW (and the other PROMs) because of severe cognitive compromise or inability to communicate. SEIQoL-DW administration was completed and deemed valid in all 48 cases (mean age 60 years, 58 % women, median Expanded Disability Status Scale score 8.5). Mean SEIQoL-DW index score was 59.1 (SD 25.5). The most commonly nominated SEIQoL-DW areas were family (94 % of the patients), relationships, and leisure activities (both 65 %). Core-POS and POS-S-MS contained 70 % of the SEIQoL-DW-nominated areas. Nevertheless, correlations between SEIQoL-DW index, Core-POS, and POS-S-MS (and the other PROMs) were negligible. CONCLUSIONS: Individualized QoL can be assessed in severely affected MS patients, providing information that is not tracked by the standard inventories Core-POS, POS-S-MS, EQ-5D-3L, and HADS.

Frequency and severity of headache is worsened by Interferon-ß therapy in patients with multiple sclerosis.

BACKGROUND: The relationship between multiple sclerosis (MS) and headache (HA) is not well known. It was reported that interferon-beta (IFNß) could induce or worsen HA. OBJECTIVE: To evaluate the impact of IFNß treatment on HA and the relationship between HA and the various commercial preparations of IFNß in mildly disabled patients with MS. METHODS: A specific questionnaire was administered to 357 relapsing-remitting MS patients. Characteristics of HAs were considered, including the temporal relationships with IFNß administration. RESULTS: One hundred and seventeen patients were treated with weekly intramuscular injections of interferon IFNß-1a (Avonex(®)), 84 with subcutaneous injections of IFNß-1b (Betaferon(®)) every other day, 48 and 108 with three times weekly subcutaneous injections of IFNß-1a (Rebif(®)) 22 mcg or IFNß-1a (Rebif(®)) 44 mcg, respectively. Three hundred and fourteen patients were affected by HA, and among them, 219 patients suffered of pre-existing HA. In this latter group, 121 subjects (55%) noted a worsening of their HA after starting IFNß therapy; this was more frequently reported by patients treated with Avonex(®) and Rebif(®) 44. Ninety-five patients experienced new HA. CONCLUSION: IFNß treatment could worsen HA in patients with pre-existing HA or cause the appearance of new HA. Among different IFNß preparations, Rebif(®) 44 and Avonex(®) seemed to be more cephalalgic than the other drugs.

ERIGO: a possible strategy to treat orthostatic hypotension in progressive supranuclear palsy? A feasibility study.

Progressive supranuclear palsy (PSP) is a neurodegenerative disease of the central nervous system, presenting with different clinical phenotypes, all involving the extrapyramidal system. Orthostatic hypotension (OH) is a common symptom of cardiovascular autonomic dysfunction. OH is defined as a fall in systolic blood pressure of at least 20 mmHg and/or a fall in diastolic blood pressure of at least 10 mmHg on standing or head-up tilt. In this pilot study, we tested the feasibility and efficacy of the ERIGO® device in managing OH non-responsive to conventional treatments in a sample of patients with PSP. OH was chosen as the primary outcome, as the symptom is a serious complication in neurodegenerative disorders, challenging the rehabilitation treatment. Six patients received intensive training using ERIGO®, a robot- assisted tilt table with an integrated leg movement system that allows progressive verticalization of the patient, and application of functional electrical stimulation. In all the participants, OH improved after the training with the device, suggesting that robotic verticalization may be a feasible and effective tool in improving blood pressure stability in patients with PSP. Further studies in larger samples, also including patients with other neurodegenerative disorders associated with OH, are needed to confirm these promising results.

Prognostic significance of the Ki-67 labeling index in growth hormone-secreting pituitary adenomas.

CONTEXT: Ki-67 is a marker of proliferation activity associated with invasiveness and prognosis in human tumors. OBJECTIVE: The aim of the study was to evaluate the Ki-67 index prognostic relevance in a group of acromegalic patients who underwent transsphenoidal surgery for a GH-secreting pituitary adenoma. MATERIAL AND METHODS: We selected 68 consecutive acromegalic patients referred to our hospital during a 5-yr period. The Ki-67 index was determined by immunohistochemistry on tissue samples obtained from each adenoma after surgery. Those patients who were not completely cured after surgery began medical therapy with somatostatin analogs (SSAs). Periodical pituitary magnetic resonance imaging and hormonal evaluation were performed during the follow-up. RESULTS: Twenty-eight of 68 patients were cured after surgery (41%). Among the 40 patients treated with SSAs, 13 were considered uncontrolled. Pituitary magnetic resonance imaging showed residual/recurrent disease in 25 of 68 patients after 6 months. No correlation was found between Ki-67 index and age, tumor size, GH, or IGF-I plasma levels. Tumors described as having cavernous sinus invasion had a higher mean Ki-67 index as compared with noninvasive tumors (P < 0.01). The Ki-67 index was significantly lower in tumors in patients cured after surgery as compared with patients considered not cured (P < 0.01) and in tumors in patients controlled by SSA therapy as compared with patients considered as uncontrolled (P < 0.05). CONCLUSION: The Ki-67 labeling index may predict clinical outcome in postsurgical management of acromegalic patients. We suggest routine Ki-67 evaluation in GH-secreting pituitary adenomas.

Is in utero early-exposure to interferon beta a risk factor for pregnancy outcomes in multiple sclerosis?

OBJECTIVE: There exist controversial and discrepant results on the risk of spontaneous abortions and teratogenesis induced by interferon treatment in people with MS.Aim of this study is to evaluate risks of the administration of INFbeta related not only to the foetus, but also to children development up to 12-months developmental milestones. METHODS: The study design is retrospective with a follow-up of babies until 18-months of their life. Thirty-eight women out of 240 with MS followed-up at Clinic MS Center of the University Hospital of Catania, Italy became pregnant in the period june 1997-may 2006. Patients were grouped into three arms: in utero exposed to INFbeta, never treated and patients who discontinued INFbeta before starting conception. Pregnancy outcomes, birth weight, 12-month developmental milestones were collected with an ad hoc questionnaire. RESULTS: Newborns of in utero exposed to INFbeta patients were little smaller for birth weight (3079.6 +/- 313.3 g), but not statistically significant, if compared with the other groups. Developmental milestones appeared within the normal range in all groups. CONCLUSIONS: Our results were particularly favourable on pregnancy outcomes, because we observed only a smaller birth weight which was not detrimental for the further development of children. We believe that INFbeta therapy might not be considered to be a reason for interruption of an intact pregnancy once the drug has been discontinued until delivery.

Static postural control disturbances among the different multiple sclerosis phenotypes: A Neurocom Balance Manager® evaluation study.

BACKGROUND: The computerized stabilometric platform can be used and privileged over clinical scales, as self-administered questionnaires to asses postural control and balance evaluation in Multiple sclerosis (MS). Aim of our study was to evaluate static postural control assessed by Neurocom Balance Manager® through the modified Clinical Test of Sensory Interaction on Balance (mCTSIB) in relapsing-remitting MS (RRMS), progressive MS (PMS) and CIS, compared to healthy controls (HC). METHODS: We screened MS patients consecutively referring to our MS Center at University of Catania, during July 2013-June 2014 diagnosed as CIS, RRMS and PMS. All MS patients underwent clinical and neurological evaluations and a complete postural exam by Neurocom Balance Manager® in order to evaluate Center of Pressure (COP), through mCTSIB. We evaluated the following parameters: Total Path Length-open eyes (TPL-OE), Total Path Length-closed eyes (TPL-CE), Sway Area-open eyes (SA-OE), Sway Area-closed eyes (SA-CE), Mean sway velocity-open eyes (MSV-OE), Mean sway velocity-closed eyes (MSV-CE). Additionally, patients were tested by Berg balance scale (BBS) for balance and Barthel Index (BI) for disability outcomes. RESULTS: Out of 170 MS patients assessed for eligibility, 163 met the inclusion/exclusion criteria and were finally enrolled. All balance parameters were found more impaired in MS group compared to controls and CIS. Moreover, no differences in terms of balance assessment were found between HC and CIS. The correlation analysis showed that BBS was strongly associated to SA-OE, SA-CE, TPL-OE and MSV-OE. We also found a correlation between BI and SA-CE. CONCLUSION: Our study revealed significant differences among HCs, CIS and MS. MS, especially PMS, exhibit the worst balance performances especially in EC trials. The higher correlation between balance parameters, especially sway area, and BBS score confirmed the reliability and sensibility of mCTSIB assessment in evaluating static postural control in MS patients.

Effects of ghrelin administration on endocrine and metabolic parameters in obese women with polycystic ovary syndrome.

INTRODUCTION: The novel peptide ghrelin displays multiple endocrine and non-endocrine actions. Its strong GH-releasing activity in humans has long been recognized. However, in obesity, ghrelin administration induces a blunted GH secretion, enhances glucose and reduces insulin levels. The effects of ghrelin administration have not been investigated in polycystic ovary syndrome (PCOS), which can be associated with obesity, hyperinsulinism, and GH hyposecretion. Leptin is a mediator for energy balance opposed to ghrelin; both of them are supposed to act as regulators of reproductive functions. AIM OF THE STUDY: Evaluate the endocrine and metabolic response to ghrelin administration in PCOS obese patients compared to body mass index (BMI)-matched and normal weight women. MATERIALS AND METHODS: Nine obese PCOS patients (BMI: 35.4+/-1.2 kg/m(2)) (OB PCOS), 6 obese controls (BMI: 38.4+/-1.1 kg/m(2)) (Ob), and 6 normal-weight women (BMI: 23+/-0.6 kg/m(2)) (NW) were enrolled in the study. In all patients we performed: 1) basal hormonal evaluation including FSH, LH, estradiol, testosterone, androstenedione, DHEAS, SHBG, 17-hydroxyprogesterone (17OHP), IGF-I, free T3 (FT3), free T4 (FT4) and ghrelin levels; 2) metabolic evaluation as follows: concentration of non-esterified fatty acid (NEFA) and oral glucose tolerance test (OGTT) (75 g); homeostasis model assessment (HOMA); glucose and insulin response to ghrelin administration (1 microg/kg); 3) measurement of GH, PRL, TSH, and leptin levels after infusion of ghrelin. RESULTS: Administration of ghrelin increased glucose and reduced insulin levels in both Ob and OB PCOS. Moreover, ghrelin enhanced GH and PRL levels in all groups but it did not modify TSH and leptin levels. GH peak and area under the curve (AUC) in OB PCOS and Ob were lower than controls (p<0.05). Similar PRL peak and AUC values were observed in all groups. CONCLUSIONS: In both obese and PCOS obese patients, leptin levels are not influenced by ghrelin administration. Moreover, the GH response after ghrelin administration is blunted. However, ghrelin exerts glucose- enhancing and insulin-lowering effects, the latter absent in NW.

Relationships between plasma CoQ10 levels and thyroid hormones in chronic obstructive pulmonary disease.

In previous works we demonstrated an inverse correlation between plasma Coenzyme Q 10 (CoQ10) and thyroid hormones; in fact, CoQ10 levels in hyperthyroid patients were found among the lowest detected in human diseases. On the contrary, CoQ10 is elevated in hypothyroid subjects, also in subclinical conditions, suggesting the usefulness of this index in assessing metabolic status in thyroid disorders. On the other hand, a low-T3 syndrome, due to reduced peripheral conversion from the prohormone T4, is observed in different chronic diseases: this condition is considered an adaptation mechanism, usually not to be corrected by replacement therapy. In order to perform a metabolic evaluation, we have studied a group of 15 patients, aged 69-82 ys, affected by chronic obstructive pulmonary disease (COPD), comparing respiratory indexes, thyroid hormones and CoQ10 levels (also normalized with cholesterol levels) in patients with low (group A) or normal (group B) free-T3 (FT3) concentrations. We found that CoQ10 levels were significantly higher in patients of group A than in B (0.91+/- 0.03 vs 0.7 +/- 0.04 microg/ml respectively); the same difference was observed when comparing the ratios between CoQ10/cholesterol in the two groups (200.16 +/- 8.96 vs 161.08 +/- 7.03 nmol/mmol respectively). These preliminary data seem to indicate that low T3 levels are accompanied by metabolic indexes of a true hypothyroidism in COPD patients. Whether this datum supports the need to perform a replacement therapy in such a condition requires further studies.

Modified autogenous latissimus breast reconstruction and the box top nipple.

During the past 3 years, the authors have been using the modified autogenous latissimus myocutaneous flap (MALF) for breast reconstruction in increasing numbers because of occasional patient and surgeon dissatisfaction with other methods of breast reconstruction. They have found this method to have unprecedented reliability, making it preferable to other forms of reconstruction in many patients. Considering the very low morbidity, the high patient satisfaction, and current economic factors, the authors are strong advocates of this form of reconstruction. A procedural outline proposed by McCraw and coworkers is followed, with some useful modifications. An elliptical transverse skin paddle is centered over the back fat roll. The area of the skin ellipse measures approximately 8 +/- 2 cm vertically and 30 +/- 5 cm transversely. After making the skin incision, a feathering technique is used in all directions through the fatty layer overlying the latissimus and in the tissue beyond the anteroposterior borders of the latissimus (not beyond 5 cm from the skin incision). By means of feathering, the shape of a breast mound can be created in the allowable tissue supported by the latissimus. A 180-degree rotation of the flap allows dependentvenous drainage and more bulk in the inferior outer quadrant, where it is needed. In the current series of 47 modified autogenous latissimus breast reconstructions, seromas were common. Other complications included one wound infection, one ulnar neuropraxia, and one fat necrosis. There were no flap necroses (partial or complete) or hematomas. The rarity of complications supports the use of this technique in selected patients. An innovative new technique for nipple reconstruction is also described. The "box top technique" of nipple reconstruction consists of four deepithelialized local flaps covered with a skin graft from the groin.

The treatment of idiopathic and secondary hydrarthrosis of the knee by intra-articular Rifamycin SV.

Fifty-three patients, 28 females and 25 males, aged from 21 to 68 years, affected with mono- and bilateral intermittent hydrarthrosis of the knee and of a non-inflammatory nature, were included in an open study. All of the knees involved were treated with intra-articular infiltrations with Rifamycin SV. The weekly dosage of Rifamycin SV was 500 mg; the average duration of treatment was 6 weeks. Follow-up 1 year after the end of treatment showed a decrease or regression in joint effusion in all of the knees treated.

Glucocorticoid replacement therapy and vertebral fractures in hypopituitary adult males with GH deficiency.

OBJECTIVE: GH deficiency (GHD) and glucocorticoid excess are associated with increased risk of fragility fractures. We aimed to evaluate whether the prevalence of vertebral fractures may be influenced by glucocorticoid over-replacement in hypopituitary males with GHD. DESIGN: Cross-sectional study. METHODS: Fifty-one adult hypopituitary patients (all males; mean age 55 years, range: 23-81) with severe adult-onset GHD (replaced in 21 patients and untreated in 30 patients) and glucocorticoid deficiency on replacement treatment were studied for vertebral fractures using a radiological and morphometric approach. RESULTS: Vertebral fractures were observed in 31 patients (60.8%) in correlation with untreated GHD, urinary cortisol values, and cortisone doses. Patients were stratified according to treatment of GHD, and current and cumulative cortisone doses. In untreated GHD, vertebral fractures occurred more frequently in patients who had received higher (greater than median) cumulative and current doses of cortisone compared with patients who had received lower (less than median) drug doses (95.2 vs 50.0%, P=0.009 and 90.5 vs 55.6%, P=0.04 respectively). In untreated GHD, fractured patients had significantly higher urinary cortisol values compared with patients without vertebral fractures (84 microg/24 h, range: 24-135 vs 49 microg/24 h, range: 30-96; P=0.04). In treated GHD patients, by contrast, the prevalence of vertebral fractures was not influenced by cumulative and current cortisone doses and urinary cortisol values. CONCLUSIONS: Glucocorticoid over-replacement may increase the prevalence of vertebral fractures in patients with untreated GHD. However, treatment of GHD seems to protect the skeleton from the deleterious effects of glucocorticoid overtreatment in hypopituitary patients.

The authors cover the care of burn injuries from start to finish, beginning with a discussion of immediate intervention and concluding with a look at psychosocial aspects of burns. Topics in the middle include early management, evaluation of the patient and classification of the burn's severity, burn resuscitation, the pathophysiology of smoke inhalation, dressing of burn wounds, escharotomies and fasciotomies, surgical management, and rehabilitation.

Autosomal recessive generalized myotonia.

Four cases of autosomal recessive generalized myotonia are reported. Attention is drawn to the fact that this condition represents a disease entity distinct from the myotonia congenita of Thomsen, which is transmitted as an autosomal dominant trait. The clinical features of the two conditions are similar, apart from minor quantitative differences. The family history is the major tool for the differential diagnosis. The possibility of the detection of heterozygotes by electromyography is discussed.
