CONTEXT: Familial pituitary adenomas occur rarely in the absence of multiple endocrine neoplasia type 1 (MEN1) and Carney complex (CNC). OBJECTIVE: Our objective was to characterize the clinical and genealogical features of non-MEN1/CNC familial isolated pituitary adenomas (FIPA). DESIGN AND SETTING: We conducted a retrospective study of clinical and genealogical characteristics of FIPA cases and performed a comparison with a sporadic population at 22 university hospitals in Belgium, Italy, France, and The Netherlands. RESULTS: Sixty-four FIPA families including 138 affected individuals were identified [55 prolactinomas, 47 somatotropinomas, 28 nonsecreting adenomas (NS), and eight ACTH-secreting tumors]. Cases were MEN1/PRKAR1A-mutation negative. First-degree relationships predominated (75.6%) among affected individuals. A single tumor phenotype occurred in 30 families (homogeneous), and heterogeneous phenotypes occurred in 34 families. FIPA cases were younger at diagnosis than sporadic cases (P = 0.015); tumors were diagnosed earlier in the first vs. the second generation of multigenerational families. Macroadenomas were more frequent in heterogeneous vs. homogeneous FIPA families (P = 0.036). Prolactinomas from heterogeneous families were larger and had more frequent suprasellar extension (P = 0.004) than sporadic cases. Somatotropinomas occurred as isolated familial somatotropinoma cases and within heterogeneous FIPA families; isolated familial somatotropinoma cases represented 18% of FIPA cases and were younger at diagnosis than patients with sporadic somatotropinomas. Familial NS cases were younger at diagnosis (P = 0.03) and had more frequently invasive tumors (P = 0.024) than sporadic cases. CONCLUSIONS: Homogeneous and heterogeneous expression of prolactinomas, somatotropinomas, NS, and Cushing's disease can occur within families in the absence of MEN1/CNC. FIPA and sporadic cases have differing clinical characteristics. FIPA may represent a novel endocrine neoplasia classification that requires further genetic characterization. [less ▲]

A multinational, multicentre, randomised, double-blind, double-dummy, crossover study (368 patients treating two attacks) was conducted to compare the efficacy and tolerability of sumatriptan nasal spray (20 mg) with dihydroergotamine (DHE) nasal spray (1 mg plus optional 1 mg). At the primary efficacy time point of 60 minutes after dosing, significantly more patients obtained headache relief (change from moderate or severe to none or mild) after treatment with sumatriptan than with DHE (53% sumatriptan, 41% DHE, p < 0.001). Significantly more patients reported relief of nausea after sumatriptan than after DHE at 60 minutes (64% sumatriptan, 49% DHE, p = 0.006). A significant difference between the two treatments was first observed at 45 minutes with respect to both headache relief (38% sumatriptan, 31% DHE, p = 0.037) and relief of nausea (55% sumatriptan, 40% DHE, p = 0.014). There were no significant differences between the two treatments for other measures of efficacy. Both treatments were well tolerated, with only 10% of patients in each group reporting one or more adverse events. The most frequently reported adverse event after sumatriptan was a bad or bitter taste, which was reported by 5% of patients. After DHE, 4% of patients reported symptoms of the nasal cavity/sinuses and 3% reported nausea and/or vomiting as adverse events. It is concluded that sumatriptan nasal spray is superior to DHE nasal spray in the relief of pain and nausea associated with acute migraine headache. [less ▲]

The administration of cyclosporin A (CyA) after autologous haematopoietic stem cell transplantation (HSCT) induces a systemic autoimmune syndrome mimicking graft-vs.-host disease (GVHD). This syndrome, termed autologous GVHD has notable anti-tumour activity in animal studies. We intended to induce autologous GVHD with CyA in patients undergoing an autologous HSCT. We prospectively studied 118 patients with miscellaneous malignancies undergoing an autologous HSCT with low-dose CyA to characterize the clinical syndrome, its frequency and clinical course, and to determine the factors affecting its incidence. Patients received CyA from d -1 through to d 28, first starting at 2 mg/kg intravenously and then orally as soon as feasible. The dose was adjusted to achieve pre-dose blood levels around 100 ng/ml. A skin biopsy was performed when a skin rash was observed. Thirty-three percent of the patients developed clinical GVHD: clinical stage 1 in 21 patients, stage 2 in seven patients, and stage 3 in three patients. Although total body irradiation (TBI) or high-dose cyclophosphamide were previously thought to be needed, autologous GVHD occurred in five out of 12 patients (42%) after a preparative regimen with high-dose melphalan alone. Autologous GVHD was significantly more frequent in patients older than 33 years, in patients who had received high doses of granulocyte-macrophage colony forming units (CFU-GM) and in those with a diagnosis of myeloid malignancy, compared with those with lymphoid malignancies or solid tumours. A significant negative association was also found with HLA-DR6. In lymphoma patients, GVHD occurred more frequently in advanced disease than in first or second complete remission (CR1-2) patients. All other factors studied were not predictive for GVHD. In conclusion, CyA-induced GVHD is reproducibly and safely induced with doses of CyA adapted to achieve blood levels around 100 ng/ml. In retrospective analysis, there was no survival advantage for patients with GVHD. Phase III trials with this approach are needed to evaluate its anti-tumoral effect. [less ▲]

ABSTRACT: BACKGROUND: The diagnostic ability of computer-based methods for cardiovascular system (CVS) monitoring offers significant clinical potential. This research tests the clinical applicability of a newly improved computer-based method for the proof of concept case of tracking changes in important hemodynamic indices due to the influence acute pulmonary embolism (APE). METHODS: Hemodynamic measurements from a porcine model of APE were used to validate the method. Of these measurements, only those that are clinically available or inferable were used in to identify pig-specific computer models of the CVS, including the aortic and pulmonary artery pressure, stroke volume, heart rate, global end diastolic volume, and mitral and tricuspid valve closure times. Changes in the computer-derived parameters were analyzed and compared with experimental metrics and clinical indices to assess the clinical applicability of the technique and its ability to track the disease state. RESULTS: The subject-specific computer models accurately captured the increase in pulmonary resistance (Rpul), the main cardiovascular consequence of APE, in all five pigs trials, which related well (R2 = 0.81) with the experimentally derived pulmonary vascular resistance. An increase in right ventricular contractility was identified, as expected, consistent with known reflex responses to APE. Furthermore, the modeled right ventricular expansion index (the ratio of right to left ventricular end diastolic volumes) closely followed the trends seen in the measured data (R2 = 0.92) used for validation, with sharp increases seen in the metric for the two pigs in a near-death state. These results show that the pig-specific models are capable of tracking disease-dependent changes in pulmonary resistance (afterload), right ventricular contractility (inotropy), and ventricular loading (preload) during induced APE. Continuous, accurate estimation of these fundamental metrics of cardiovascular status can help to assist clinicians with diagnosis, monitoring, and therapy-based decisions in an intensive care environment. Furthermore, because the method only uses measurements already available in the ICU, it can be implemented with no added risk to the patient and little extra cost. CONCLUSIONS: This computer-based monitoring method shows potential for real-time, continuous diagnosis and monitoring of acute CVS dysfunction in critically ill patients. [less ▲]

Acarbose, an alpha-glucosidase inhibitor, is a new antihyperglycaemic agent which has been proposed as add-on therapy in Type 2 diabetic patients not well-controlled with diet alone, sulphonylurea, metformin or insulin, and in Type 1 diabetic patients with large meal-related plasma glucose excursions. Numerous controlled studies investigating the clinical effects of acarbose in Type 2 diabetes versus either placebo or, more rarely, versus a reference drug (sulphonylurea or metformin) have been published during the last 10 years. All placebo-controlled studies have demonstrated the superiority of acarbose, at a dose of 150-600 mg/day, in decreasing fasting and postprandial glucose levels as well as HbA1c concentrations (mean decrease of 0.7%), whether acarbose was given as first-line therapy in diet-treated diabetic patients or in combination in individuals already receiving a sulphonylurea, metformin or insulin. Only a few controlled studies have compared the effects of acarbose with those of either sulphonylurea or metformin, yielding controversial results. In Type 1 diabetic patients, a small reduction of HbA1c levels was also reported after addition of acarbose to insulin therapy, which in some cases allowed a slight reduction of daily insulin needs. All these favourable biological effects occurred without exposing the patient to hypoglycaemia or weight gain. A few studies have also reported favourable effects on postprandial lipid profile and some other vascular risk factors. However, it is not clear whether the extra cost of acarbose, when compared to that of older oral antidiabetic agents, is justified since no study has yet demonstrated its potential benefit on the complications and long-term prognosis of diabetic patients.

Abstract The objective of this retrospective study was to report the efficacy of a single daily oral dose of phenylpropanolamine (PPA) in the treatment of urethral sphincter mechanism incompetence (USMI) in bitches. Nine bitches diagnosed with USMI were treated with a single daily dose (1.5 mg/kg) of PPA for at least 1 month. Urethral pressure profiles (UPP) were performed in 7 dogs before treatment and repeated in 4 of them after treatment. Treatment with PPA resulted in long-term continence in 8/9 bitches. One dog did not respond to PPA and was treated surgically later. Recheck UPPs showed a significant increase in maximal urethral closure pressure in the 4 bitches after treatment with PPA compared to before treatment. In conclusion, long-term continence can be achieved in bitches affected with USMI after administration of a single daily dose of PPA (1.5 mg/kg). [less ▲]

Background Cardiac morphologic and functional changes consistent with cardiomyopathy have been reported in field cases of calves with accidental doxycycline overdosing. The purpose of this study was to evaluate clinically the cardiac effects of an experimentally-induced doxycycline overdosing in healthy calves. Twelve 2 months-old healthy Belgian Blue calves were studied. Six of them (group 1) received the normal dose (5 mg/kg, BID) and the six others (group 2) received five times the normal dose (25 mg/kg, BID) of oral doxycycline for five consecutive days (D1 to D5). Each calf was clinically examined daily. Measurement of serum AST, CK, Iso-CKs and LDH activities and an echocardiographic examination were performed before (D0) and one day after (D6) the last doxycycline administration. An ECG tracing was recorded at D0, D4, and D6. Results In both groups, no clinical, blood, echocardiographic or electrocardiographic changes suggestive of a cardiomyopathy were observed. Only a decreased appetite was observed in the calves of the group 2 between D3 and D6. Conclusions This trial failed to reproduce cardiac changes reported in accidental doxycycline-poisoning in calves, suggesting that high doses of doxycycline may not be the only etiologic factor of the cardiomyopathy reported in the field cases.
