Abstract
STUDY QUESTION Is there an added diagnosis value of buccal cell FISH analysis compared with blood lymphocyte chromosomal investigations in patients with Turner syndrome (TS)? SUMMARY ANSWER Buccal cell FISH analysis, a non-invasive technique, modified the chromosomal results obtained with the blood karyotype in 17 patients (12%) of our cohort. WHAT IS KNOWN ALREADY Few studies have evaluated buccal cell FISH analysis and compared them with blood karyotype in patients with TS. STUDY DESIGN, SIZE, DURATION A prospective, monocentric cohort study was conducted in a rare diseases centre (CMERC) between July 2017 and August 2019. PARTICIPANTS/MATERIALS, SETTING, METHODS In total, 142 adult patients with TS, and at least 5% 45,X cells in a previous blood karyotype, were recruited. All the patients' files were included in the CEMARA database. This national database has been declared to the French data protection agency (CNIL approval number 1187326). In compliance with French law, consent regarding non-opposition to collect and use the data was obtained from each patient. A FISH analysis on a buccal smear was performed. MAIN RESULTS AND THE ROLE OF CHANCE The percentage of 45,X cells was identical between the two tissues in only 32.4% of cases. The discrepancy was higher than 41% for 12% of the cohort. The percentage of 45,X cells was higher in blood in 53 (37.3%) patients, and higher in buccal cells in 43 (30.3%) of cases. In 17 (12%) cases, the blood karyotype had to be reconsidered in regard to the buccal cell analysis. LIMITATIONS, REASONS FOR CAUTION It would have been interesting to evaluate karyotypes in cells from other tissues such as cells from skin biopsy or from the urinary tract and even from blood vessels or gonads in case of surgery and to compare them with each patient's phenotype. However, most of the time, these tissues are not available. WIDER IMPLICATIONS OF THE FINDINGS Although blood lymphocyte karyotype remains the gold standard for the diagnosis of TS, buccal cell FISH analysis is an efficient tool to evaluate the global chromosomal constitution in these patients, thus allowing them to have better care and follow-up. For instance, identifying a Y chromosome can prevent the occurrence of a gonadoblastoma, as gonadectomy should be discussed. On the other hand, finding normal XX cells in a patient with a previous diagnosis of homogenous 45,X TS, may be psychologically helpful and relevant for gynaecological care. STUDY FUNDING/COMPETING INTEREST(S) No specific funding was sought for the study. The authors declare no competing interests. TRIAL REGISTRATION NUMBER N/A.

Abstract
Background Inhalation exposure to fine and ultrafine particles (UFPs) has been associated with respiratory diseases. However, little is known on the quality, threshold levels and concentration of these particles causing adverse health effects. Methods The impact of occupational exposure to submicrometer and UFPs was assessed in 30 healthy police shooting instructors by clinical investigation, self-assessment questionnaire, sputum and spirometry and compared to a control group. General laboratory chemistry parameters, circulating cytokines (interleukin [IL]-2, IL-4, IL-5, IL-6, IL-8, interferon-gamma [IFN-γ]), and granulocyte macrophage colony-stimulating factor (GM-CSF) in serum were measured. UFP exposure was recorded by Scanning Mobility Particle Sizer. Results Concentrations of submicrometer sized airborne particles (< 700 nm) measured between 3.34 × 105/cm3 and 7.58 × 105/cm3 at shooting sites, with highest concentrations found in the UFP range (< 100 nm). The size of the monodispersed particles ranged from 54.74 ± 16.25 nm to 98.19 ± 22.83 nm. Short term exposure (4 h) to high levels of UFPs caused an increase of IFN-γ in exposed subjects (p = 0.022). 24 h after exposure a significant decrease of IgG, albumin fibrinogen and factor VII was found. Neither directly after 4 h of high levels UFPs exposure nor 24 h after exposure subjective complaints or objective measurements indicating adverse respiratory effects in exposed subjects were found. Conclusions No consistent indications for adverse respiratory or inflammatory effects directly following exposure and 24 h after exposure to high levels of UFPs in our study group were detected. However we showed the assessment of short-term exposure effects at a genuine occupational setting, which might is relevant when a risk assessment of high level occupational exposures to UFPs is considered.

Abstract
OBJECTIVE This study compares the antihypertensive efficacy and tolerability of valsartan, a novel angiotensin II antagonist, given with hydrochlorothiazide (HCTZ) vs placebo or vs valsartan or HCTZ alone. DESIGN 871 adult out-patients with essential hypertension participated in this double-blind study. Patients were randomised in equal number to receive either combination therapy of valsartan (80 mg or 160 mg) and HCTZ (12.5 mg or 25 mg), or valsartan (80 mg or 160 mg) or HCTZ (12.5 mg or 25 mg) alone, or placebo. Patients were treated once daily for 8 weeks and assessed at 2, 4 and 8 weeks after randomisation. MAIN OUTCOME MEASURES The primary efficacy variable was change from baseline in mean sitting diastolic blood pressure (MSDBP) at end-point. The secondary variable was change in mean sitting systolic blood pressure (MSSBP) from baseline to end-point. RESULTS All active treatments produced a statistically significant difference in MSDBP (P < 0.001) from baseline to end-point compared with placebo. Similar results were obtained for MSSBP. All combination regimens produced a statistically significantly greater reduction in MSDPB and MSSBP than the corresponding monotherapies. Dizziness and headache were the most common treatment-related adverse experiences reported. Hypokalaemia, associated with the use of thiazide diuretics, was more commonly reported in the higher dose HCTZ 25 mg groups. CONCLUSIONS Valsartan 80 mg and 160 mg act additively with HCTZ 12.5 mg or 25 mg to lower MSDBP and MSSBP in patients with essential hypertension. The addition of HCTZ to valsartan 80 mg or 160 mg was well tolerated.

Abstract
OBJECTIVE To compare the efficacy, safety and tolerability of valsartan to an angiotensin-converting enzyme (ACE) inhibitor, lisinopril, and placebo in patients with mild-to-moderate essential hypertension. DESIGN A total of 734 men and women were randomised in this multicentre, double-blind, optional titration, parallel group trial. Volunteers received valsartan 80 mg (n = 364), lisinopril 10 mg (n = 187) or placebo (n = 183) daily for 4 weeks, with subsequent titration of dose depending on response to treatment (valsartan 80 mg titrated to valsartan 160 mg once daily or valsartan 80 mg twice daily, lisinopril 10 mg titrated to lisonopril 20 mg once daily). Patients were assessed at 4, 8 and 12 weeks. MAIN OUTCOME MEASURES The primary variable was change from baseline in mean sitting diastolic blood pressure (SDBP). Other efficacy variables included sitting systolic blood pressure (SSBP) and percentage of 'successful' responders (SDBP <90 mm Hg or > or =10 mm Hg reduction from baseline). RESULTS All active treatment groups were shown to demonstrate significant reductions in SDBP compared to placebo at endpoint of therapy (least mean square reduction from baseline: valsartan 80/160 mg: -5.25 mm Hg (Cl -7.17, -3.34, P< 0.001); valsartan 80/80 mg twice daily: -5.63 mm Hg (Cl -7.51, -3.75, P< 0.001); lisinopril 10/20 mg: -6.93 mm Hg, (Cl -8.81, -5.05, P< 0.001). There were no statistically significant differences between the active treatment groups at endpoint of therapy. In patients requiring titration to a higher dose (placebo n = 142, valsartan 80/80 twice daily n = 124, valsartan 80/160 n = 114, lisinopril 10/20 n = 120), there were no significant treatment differences between valsartan 160 mg given as a single daily dose or as 80 mg twice daily (P = 0.658). Both valsartan and lisinopril produced similarly high percentages of 'successful' responders at endpoint of therapy. A somewhat higher frequency of drug related cough was observed in lisinopril treated patients (8%) compared to valsartan (1.1%) or placebo (0.5%). CONCLUSIONS Valsartan 80 mg daily, with titration to 160 mg daily as required, provides similar antihypertensive efficacy to lisinopril 10 mg daily with titration to 20 mg daily. Valsartan provides a new antihypertensive agent with comparable efficacy to lisinopril and appears to be associated with a reduced incidence of cough.

Abstract
A single-blind, run-in, randomized, double-blind, parallel-group, placebo-controlled comparison trial was conducted to assess the safety and efficacy of low-dose amlodipine 2.5 mg daily, low-dose benazepril 10 mg daily, and the combination of the two drugs at the same doses used once daily in patients (n = 401) with mild to moderate (stages I and II) systemic hypertension. Both monotherapy regimens were shown to significantly reduce both systolic and diastolic blood pressure compared with baseline placebo values, and the combination regimen was shown to be superior in lowering systolic and diastolic blood pressure when compared with either of the monotherapy regimens. The combination therapy also resulted in a greater percentage of patients having successful clinical response in mean sitting diastolic blood pressure. The amlodipine and benazepril regimen was also shown to be associated with a similar incidence of adverse experiences as the active monotherapy or placebo regimens, although the group given combination therapy appeared to have a lower incidence of edema than the group given amlodipine alone. Low-dose amlodipine (2.5 mg) plus benazepril (10 mg) provides greater blood-pressure-lowering efficacy than either monotherapy, and has an excellent safety profile.

Abstract
This normative study presents a clinically applicable method with which to obtain Psychoacoustical Tuning Curves: data are obtained with clinical audiometers, and measurements are performed on normal-hearing non-trained volunteers. A simultaneous masking method with test frequency of 4,000 Hz was used, withmasking being incremented in 5 dB or 1 dB steps. One group of subjects was tested three times with 5 dB incrementing steps to evaluate the method's reproducibility. A second group of subjects was measured twice with 1 dB incrementing steps, to compare the reproducibility of the 1-dB step measurements, and the difference between the 1-dB step and 5-dB step measurements. All the data were evaluated as normative values. The method presented proves to have a good reproducibility. Although testing with 1-dB incrementing steps provides more accurate measurements and curves with steeper slopes, the 5-dB incrementing step method is more practicable. Interest variability evaluation indicates that differences between two measurements performed on the same person exceeding 120 Hz (2 SD) bandwidth can be interpreted as significant.

Abstract
The functional and anatomical results of a series of 181 consecutive allograft tympanoplasties for ears with drum perforation and an intact ossicular chain were retrospectively reviewed and related to preoperative factors. Drum closure was realized in 92% (166 of 181 cases evaluated 1 year after surgery), and 96.6% of the reconstructed drums were still intact 3 years after surgery (118 cases evaluated). An air-bone gap of less than 21 dB was reached in 79.6% (of a total of 162 cases) 1 year after surgery, and in 78% (of a total of 118 cases) 3 years after surgery. Age, contralateral pathology, the wet or dry status of the ear preoperatively, and the preoperative air-bone gap had no influence on anatomical results. The preoperative air-bone gap did not predict the postoperative air-bone gap. The influence of age and existence of contralateral pathology on hearing gain was only visible in some of the strictly defined patient groups. The wet preoperative status of the ear generally predicted lower functional gain.

Abstract
For some time health promotion and disease prevention have been expected tenets of medical practices with the public. However, the medical profession has only recently emphasized prevention and wellness promotion as required curricula for study at the undergraduate and graduate levels. Family physicians have been at the forefront in accepting this additional responsibility, but actual implementation of such practices has been difficult for the individual physician. To address this needed transitional step from public demand to practice, a wellness program for residents, faculty, staff, and patients was designed for the Family Practice Residency Program at Cheyenne.

Abstract
The authors present a method for the post-operative evaluation of middle ear surgery. They suggest that such a framework should be worked out in greater detail by specialised international societies, so that, as a final result, an international, standardised method for data recording, processing and reporting would be established.
