Audit of minimally-invasive surgery for submandibular sialolithiasis

Sialolithiasis is one of most common diseases to affect major salivary glands, with a symptomatic incidence of 27 cases per million per annum. The majority form within the submandibular gland where minimally-invasive treatments have all but eliminated adenectomy. All records of patients presenting with submandibular stones between 1997 and 2015 were reviewed. Stones <5 mm were retrieved through endoscopic or radiographic techniques, 5-7 mm stones were initially considered for extra-corporeal shock wave lithotripsy, but after poor results were treated through intraoral surgical removal with those >7 mm. Follow up was performed at 1 week and 3 months with current status performed with postal and telephone questionnaires. 378 patients had 424 stones removed, successful retrieval in 94% (n = 356), with 50 having had previous failures. Median number of stones per patient was 1 (range 1-4), with a mean size of 8.6 mm (SD 4.5 mm) mainly located at the hilum (50.5%), anterior duct (30%) and Genu (17%). 256 patients (65%) treated through intraoral surgical extraction, 92 (24%) endoscopic alone. Inpatient stay was 1.4 days in first third and 0.5 days in final third. Adenectomy occurred in 14 patients, due to failure to retrieve the sialolith or unresolved symptoms. Complications involved 11 patients with permanent paraesthesia, 7 ranulas and 14 strictures. Patients with preoperative strictures were more likely to develop complications (p = 0.002) with paraesthesia being most common. Intraoral minimally-invasive surgery is aesthetic, curative and spares the risk to marginal mandibular nerve and submandibular gland. Length of inpatient stay improved and ranula risk reduced throughout the study.     

Cortical Somatosensory Excitability Is Modulated in Response to Several Days of Muscle Soreness

Changes in excitability of the sensorimotor cortex have been demonstrated in clinical musculoskeletal pain, although the timing is unknown. Eccentric exercise provokes delayed-onset muscle soreness providing a model to study the temporal profile of sensorimotor cortical plasticity during progressively developing muscle soreness. Twelve healthy participants performed eccentric exercise of the wrist extensors. Likert pain scores, pressure pain thresholds at the extensor carpi radialis (ECR) muscle, somatosensory evoked potentials from electrical stimulation of the radial nerve, maximal wrist extension force, and ECR motor evoked potentials to transcranial magnetic stimulation were recorded before (baseline) and at 2 hours (2-h post), 2 days (day 2), and 6 days (day 6) after exercise. Compared with baseline, 1) the Likert pain score was increased at 2-h post and increased further at day 2 (P < .01); 2) the ECR pressure pain thresholds were decreased at day 2 (P < .001); 3) the P45 amplitude of the somatosensory evoked potential from central-parietal recording sites was increased at day 2 (P < .001); 4) maximal wrist extension force was reduced 2-h post and at day 2 (P < .002); and 5) the cortical area from which ECR motor evoked potentials could be elicited was reduced at 2-h post and at day 2 (P < .03). A decrease in the ECR pressure pain thresholds was correlated (P < .027) with an increase in the P45 amplitude at a centroparietal recording site.

Addressing Emergency Department Issues Using Advanced Practice in Saudi Arabia

Emergency departments (EDs) struggle to manage safe, effective care in the face of increasing patient volume. The role of the nurse practitioner has been shown to improve key factors such as waiting times and the patients’ experience in the ED. This quality improvement project evaluates the effectiveness of a nurse practitioner based in the ED. One nurse practitioner managed patients presenting with minor trauma over 3 months. A pre-post intervention approach was implemented and evaluated. Over 3 months, waiting times and the number of patients who left without being seen were reduced.     

Dietary Salt Intake and Discretionary Salt Use in Two General Population Samples in Australia: 2011 and 2014

The limited Australian measures to reduce population sodium intake through national initiatives targeting sodium in the food supply have not been evaluated. The aim was, thus, to assess if there has been a change in salt intake and discretionary salt use between 2011 and 2014 in the state of Victoria, Australia. Adults drawn from a population sample provided 24 h urine collections and reported discretionary salt use in 2011 and 2014. The final sample included 307 subjects who participated in both surveys, 291 who participated in 2011 only, and 135 subjects who participated in 2014 only. Analysis included adjustment for age, gender, metropolitan area, weekend collection and participation in both surveys, where appropriate. In 2011, 598 participants: 53% female, age 57.1(12.0)(SD) years and in 2014, 442 participants: 53% female, age 61.2(10.7) years provided valid urine collections, with no difference in the mean urinary salt excretion between 2011: 7.9 (7.6, 8.2) (95% CI) g/salt/day and 2014: 7.8 (7.5, 8.1) g/salt/day (p = 0.589), and no difference in discretionary salt use: 35% (2011) and 36% (2014) reported adding salt sometimes or often/always at the table (p = 0.76). Those that sometimes or often/always added salt at the table and when cooking had 0.7 (0.7, 0.8) g/salt/day (p = 0.0016) higher salt excretion. There is no indication over this 3-year period that national salt reduction initiatives targeting the food supply have resulted in a population reduction in salt intake. More concerted efforts are required to reduce the salt content of manufactured foods, together with a consumer education campaign targeting the use of discretionary salt.     

Health-related quality of life in Iranian women with polycystic ovary syndrome: a qualitative study

Background

Polycystic ovary syndrome (PCOS) is associated with a range of challenging symptoms which impact patient’s lives. Iranian women with PCOS are likely to face a number of unique difficulties given particular societal and cultural norms for women. Understanding health-related quality of life (HRQoL) from a patients’perspective is critical to developing the appropriate support interventions. The present study aimed to generate an in-depthunderstanding of HRQoL Iranian women with PCOS.

Methods

Twenty Iranian women were interviewed and data was subjected to thematic analysis.

Results

Women reported substantial effects of PCOS on their quality of life, Themes generated from the data related to sexual - physical problems (An unsexualised self: loss, change and pain; and Being pained and painful); exposure and nvasion: the rejecting and invading social world (Concealing and Avoiding and Public property: public scrutiny), diminished self and diminished life (Infertile as inferior and Exhausted mind andbody) respectively.

Conclusion

PCOS is a physical - sexual, psychological and social syndrome; therefore, it is necessary to taking a more holistic approach to patient care beyond treating physical symptoms.

     

COVID-19 infection causes a reduction in neutrophil counts in patients taking clozapine

BackgroundMonitoring of white cell counts during clozapine treatment leads to cessation of therapy if levels fall below pre-determined values. Reductions in white cell counts, driven by lower levels of lymphocytes, have been observed with coronavirus disease 2019 (COVID-19). Neutropenia during COVID-19 has not been reported. We present data for 56 patients who were taking clozapine and had COVID-19.MethodsWe included patients who were taking clozapine at the time they tested positive for COVID-19. We compared absolute neutrophil counts, lymphocyte counts and white cell counts between baseline and the first week of infection, and baseline and the second week of infection.ResultsWe observed reductions in absolute neutrophil counts (p = 0.005), lymphocyte counts (p = 0.003) and white cell counts (p < 0.001) between baseline and the first 7 days of COVID-19. All cell counts had returned to baseline levels by days 8 to 14. Six patients experienced neutropenia (absolute neutrophil counts < 2.0 × 10⁹/L) and of those, 4 underwent mandatory cessation of clozapine. For 3 patients, clozapine treatment had been established for more than 6 months with no previous neutropenia, neutrophil levels returned to baseline within 2 weeks and no further neutropenia was observed on restarting treatment.LimitationsThis was a retrospective chart review; larger cohorts are required. Clozapine plasma levels were largely not measured by clinicians.ConclusionThese data strongly suggest that mild neutropenia in the acute phase of COVID-19 in patients who are well established on clozapine is more likely to be a consequence of the virus than of clozapine treatment.
