Incidence of seropositive rheumatoid arthritis in population-based studies in Northern Savo, Finland, during 1980-2020.

The objective is to evaluate the incidence of seropositive rheumatoid arthritis (RA) over 40-year period in Northern Savo, Finland. Data on new seropositive RA patients according to the American College of Rheumatology (ACR) 1987 classification criteria were collected in 2020-2021. In 2020 data on tobacco exposure, patient-reported dental health and living in residences with fluoridated tap water were gathered.

Transferrin receptor expression on reticulocytes as a marker of iron status in dialyzed patients.

Background: Erythropoietin therapy should be accompanied by an adequate iron supply in order to avoid functional iron deficiency (FID) related to enhanced erythropoiesis. Therefore, accurate monitoring of the body's iron homeostasis is needed. This study was conducted to investigate whether transferrin receptor (TfR) expression on reticulocytes can reflect iron status in patients with chronic renal failure (CRF).

The effectiveness of a scalp cooling cap in preventing chemotherapy-induced alopecia.

Aims And Background: Hair loss is one of the most unpleasant side effects associated with chemotherapy treatments. It causes emotional disturbances and constantly reminds the patient of the disease. This study analyzed the effectiveness of scalp cooling caps in preventing alopecia among 64 patients.

Muscle symptoms associated with statins: a series of twenty patients.

The aim of this study was to examine the clinical profile of statin-induced myalgia in patients with no apparent predisposing factors. Patients who reported muscle complaints that limited daily functioning during statin use were prospectively identified among the patients of Kuusankoski District Hospital and its catchment area, a population of about 100,000, between January 2003 and July 2004. Twenty patients in whom the muscle complaints were probably attributable to the use of a statin were included in this series.

Central auditory processing of durational changes in complex speech patterns by newborns: an event-related brain potential study.

In this study, newborns' ability to discriminate durational changes in the fricative /s/ within a nonsense word was investigated. The results showed that infrequent increments and decrements of a speech sound duration elicit a mismatch negativity kind of response in sleeping human newborns. In the auditory event-related potential to these deviant stimuli two negative waves of this response were revealed.

A study of the effects of lisinopril when used in addition to atenolol.

A double-blind, parallel group multicentre study was carried out to compare the effects of adding once daily treatment with lisinopril 10 or 20 mg and placebo to the treatment of 100 patients whose blood pressure was inadequately controlled with once daily atenolol 50 mg. Following a two-week run-in period, patients with a lying DBP between 95 mmHg and 115 mmHg were randomised to either lisinopril 10 mg or placebo once daily for four weeks. Blood pressure measurements were made approximately 24 h after the previous dose of study medication.

Effect of the Choice of Primary Chemotherapy on the Cumulative Length of Stay in Hospital for Multiple Myeloma.

The actual use of hospital beds for patients with multiple myeloma was calculated from a randomised trial of primary treatment with either melphalan and prednisone (MP, 66 patients) or intensive combination chemotherapy with vincristine, cyclophosphamide, lomustine, melphalan and methylprednisolone (MOCCA, 64 patients). The survival of the patients was similar in both arms, and the samples, 20 and 32 patients, respectively, were well representative for the whole arms. The average numbers of hospital days were similar fur both arms.

Antianginal effect of isosorbide dinitrate spray in patients with exercise-induced stable angina.

Ten patients with stable exercise-induced angina took part in this study. Isosorbide dinitrate and placebo sprays were administered in a double-blind, randomized crossover study. The dose of isosorbide dinitrate given was two squirts (= 2.

The steady-state pharmacokinetics of tamoxifen and its metabolites in breast cancer patients.

The steady-state pharmacokinetics of tamoxifen and its metabolites was studied in sixteen patients with advanced mammary cancer. Patients were randomized to receive tamoxifen given as Tamofen, Leiras, or as Nolvadex, ICI, 20 mg twice daily for 16 weeks in a cross-over study. Plasma and urine samples were analyzed during one dose interval (12 h) after treatment for 8 and 16 weeks.

Vibrotactile atonal interval correlated with activity in peripheral mechanoreceptive units innervating the human hand.

The quality of sensations and the vibrotactile atonal interval-the gap between detection and vibration thresholds-were studied with vibratory stimuli of varying frequency (20, 80 and 160 Hz) and duration (100, 400 and 800 ms) applied to the hairy and glabrous skin of the hand. Detection and vibration thresholds were also determined while simultaneously recording single unit activity from the radial nerve innervating the hairy skin of the hand. Both thresholds were lower on the glabrous than the hairy skin, and the thresholds decreased on both skin areas with increasing vibration frequency.

Somatosensory evoked potentials associated with tactile stimulation at detection threshold in man.

Somatosensory evoked potentials elicited by sub- and supraliminal tactile pulses were studied during continuous threshold measurement. Two threshold methods were used: a modified tracking method and a detection method. With both methods threshold estimates of the same order of magnitude were obtained.

Bioavailability of a combination preparation of trimethoprim and folic acid.

The bioavailability of folic acid and trimethoprim was investigated from a combination preparation of folic acid (0.25 mg) and trimethoprim (100 mg) in ten healthy adult volunteers. Peroral administration of the preparation resulted in a mean peak plasma concentration of trimethoprim 1.

Bioavailability of paediatric mixtures containing phenoxymethylpenicillin calcium or potassium salt.

The bioavailability of the calcium and potassium salts of phenoxymethyl-penicillin (dose 38,000 I.U./kg) was investigated in eight healthy adult volunteers.

Peripheral neural basis of tactile sensations in man: II. Characteristics of human mechanoreceptors in the hairy skin and correlations of their activity with tactile sensations.

Properties of the human mechanoreceptors in the hairy skin of the back of the hand were studied by microelectrode measurements from the radial nerve. Correlations of unit activity with sensations elicited by tactile pulses (single cycle sinusoids of 20, 60 and 150 HZ) were examined with simultaneous measurements of unit activity and sensation thresholds and magnitude. A total of 264 mechanoreceptive units were identified.

Dry polyacrylamide batch method for determining the binding of various compounds by plasma proteins.

A new modification of the gel diffusion method has been developed using dry polyacrylamide gel. The theoretical background is explained and the mathematical formulas are presented. The properties of the gel are studied, concerning the absorbing capacities and changes in ion equilibria.
