Telemedicine and Multiple Sclerosis: A Survey of Health Care Providers Before and During the COVID-19 Pandemic.

Background: Telemedicine provides a gateway to specialty care that, otherwise, patients with multiple sclerosis (MS) could have difficulty accessing. Studies have shown that telemedicine provides a valid alternative to in-person visits. There are limited data on the strengths and limitations of telemedicine from the perspective of MS providers.

[Sialorrhea: hypersalivation and drooling. An underestimated problem in medical practice].

On the contrary to hyposalivation/xerostomia there is a little attention paid in the literature for discussing the problem of the patient having too much saliva. In most of cases, pathogenesis of sialorrhea is not known. Due to the small number of patients involved in the studies it is difficult to get exact data.

Fluoride concentrations of unstimulated whole and labial gland saliva in young adults after fluoride intake with milk.

Following a fluoride depletion period 6 subjects repeatedly rinsed with 30-ml volumes of milk with or without added fluoride (5 ppm). Rinsing time was timed according to the measurements on how long it took to drink 200 or 500 ml milk. Rinsing with fluoridated milk for a total interval of 20 and 60 s, respectively, did not influence significantly the fluoride concentration of unstimulated centrifuged whole saliva 45 min later.

Study of saliva secretion and the salivary fluoride concentration of the human minor labial glands by a new method.

Unstimulated and stimulated flow rate from minor lower labial glands and the fluoride concentration of resting whole and labial saliva were measured over 15 min using a novel method avoiding eversion of the lips. Resting salivary flow rate was measured as 1.09+/-0.

Protrusion and mixed deformities.

Background: Considerable confusion is encountered in the literature relating classification respectively surgical repair of the anterior chest wall deformities in view of the asymmetric types which are arbitrarily ranged in one of the two main groups (impressions, protrusions).

Methods: Out of 420 operations 89 (21%) were performed for pure protrusion, and 64 (15%) for mixed deformities, with asymmetric impression and protrusion present at the same time. Mixed deformities were limited to the parasternal area in 10 and extended to the entire anterior chest wall in 54 cases.

[Central bronchoplastic procedures in Hungary and their outcome (198-1993)].

Bronchoplastic procedures involving the main carina are declared as central bronchoplasties. A nation-wide collection of these interventions performed between 1980 and 1993 is analysed. The study is on a total of 154 operations, that were 16 bifurcation resections and 14 stem bronchus resections without parenchyma sacrifice, 61 sleeve or wedge pneumonectomies and 63 tracheal sleeve or wedge right upper lobectomies or carina-plasties.

[The effect of H2-receptor blockers (cimetidine and ranitidin) on parotid gland secretion and salivary carbonic anhydrase activity in the rat].

It has been demonstrated, that the H2-receptor antagonists: cimetidine and ranitidine-administered in doses of the same order of magnitude as reported for the inhibition of rat gastric secretion and development of the experimentally induced gastric and duodenal ulcer-are capable of increasing significantly the parotid secretion evoked by the cholinergic stimulant bethanechol. The salivary carbonic anhydrase activity was also elevated after combined treatment of bethanechol(+)-cimetidine. The similar action of the two H2-antagonists appears to suggest that their effect on salivation is connected probably with the cholinergic activity and it is concluded that the combination of bethanechol with these blockers may improve the esophageal clearance, an action that may be beneficial in the treatment of the gastroesophageal reflux disease.

[Chromatographic study of salivary carbonic anhydrase isoenzymes in rats].

Authors could purify two isoenzymes (designated CA1 and CA2) from the submandibular gland but only one (CA1) from the submandibular saliva by gel filtration and affinity chromatography. They concluded, that CA1 is a high molecular weight (approximately 90 kD) membrane-bound glycoprotein and CA2 is a cytosolic isoenzyme with lower molecular weight (30 kD) comparing to CA1.

Detection of colon distension in colonostomy patients.

Inborn and learned ability to detect mild, nonpainful distension of the sygmoid colon was examined in 22 patients who underwent colonostomy one year or more before the investigation. The colon was distended by a balloon inserted 10 cm below the orifice of the artificial anus. Each subject participated in three sessions on three consecutive weeks with several experimental tasks in each session.

[24-hour pH monitoring in the treatment of gastroesophageal reflux].

The 24 hour pH monitoring is superior to other methods in assessing chemical activity and quantitative characteristics of gastroesophageal reflux (GER). This technique supported by the pull-through esophageal manometry, reveals and classifies the patients for either medical or surgical treatment. The comparison of the diagrams recorded before and after surgical repair, is a reliable guide in evaluating the efficacy of the anti-reflux procedure.

Surgical pathology of bullae with and without pneumothorax.

Experience with 2030 patients admitted for an actual episode of spontaneous pneumothorax, and with 370 patients hospitalized for bullous emphysema is thoroughly analyzed. Out of these groups, 400 patients (318 and 82 respectively) underwent an open thoracotomy. Macroscopic operative findings were divided into 8 groups.

Sleeve resection and other bronchoplasties in the surgery of bronchogenic tumors.

One-hundred and fifty-eight sleeve resections and other bronchoplasties were performed for bronchogenic tumors in the last 20 years. Carcinoma was the indication in 143 and other tumors in 15 cases. Histology and staging conditions are outlined.
