METHODS AND RESULTS: This innovation involves two lateral skin flaps being sutured into an incision on either side of the lateral wall of the trachea. This results in an elongated, broadened and elliptical tracheostoma, mimicking that of a fish mouth.
CONCLUSION: Benefits of the fish mouth technique include adequate stoma size for respiration, easier clearing of secretions, self-sufficiency without a stent, easier cleaning of a tracheoesophageal voice prosthesis, and stoma occlusion for voice production. The fish mouth technique is easily reproducible and suitable for those with a voice prosthesis.
METHODS: Sixty-six (66) patients with unilateral uncomplicated inguinal hernia were randomized into 34 patients in the tacker and 32 patients in cyanoacrylate glue mesh fixation in TEP repair. The extent of surgical trauma was evaluated by measuring inflammatory markers of C-reactive protein, white blood cell count at 48 h, and ESR at 3 months postoperatively. Postoperative acute and chronic pain was assessed by recording the visual analogue scale scores and surgical complications were recorded over 3 months of the study period.
RESULTS: The median CRP and WBC levels at postoperative 48 h in both groups raised significantly from the baseline values (p 0.05). The median ESR level increased significantly at 3 months postoperatively from baseline in the glue mesh fixation group only (p 0.05). There was no significant difference for VAS scores at all timelines between the tacker and glue mesh fixation group (p > 0.05).
CONCLUSION: Cyanoacrylate glue mesh fixation technique as an alternative method to mechanical fixation in TEP repair is comparable to tacker and can be considered to be safe and feasible.
METHODS: Twelve relevant manuscripts were sourced from a total of 7288 search results obtained using PubMed, Medline and Google Scholar. The search keywords used were COVID-19, nasopharyngeal, oropharyngeal, swabs, SARS and CoV2. Original manuscripts were obtained and analysed by all authors. The review included manuscripts which have not undergone rigorous peer-review process in view of the magnitude of the topic discussed.
RESULTS: The viral load of SARS-CoV-2 RNA in the upper respiratory tract was significantly higher during the first week and peaked at 4-6 days after onset of symptoms, during which it can be potentially sampled. Nasopharyngeal swab has demonstrated higher viral load than oropharyngeal swab, where the difference in paired samples is best seen at 0-9 days after the onset of illness. Sensitivity of nasopharyngeal swab was higher than oropharyngeal swabs in COVID-19 patients. Patient self-collected throat washing has been shown to contain higher viral load than nasopharyngeal or oropharyngeal swab, with significantly higher sensitivity when compared with paired nasopharyngeal swab.
RECOMMENDATIONS: Routine nasopharyngeal swab of suspected COVID-19 infection should take anatomy of the nasal cavity into consideration to increase patient comfort and diagnostic yield. Routine oropharyngeal swab should be replaced by throat washing which has demonstrated better diagnostic accuracy, and it is safe towards others.
METHODS: We searched the PubMed and Google Scholar on 15th May 2020, with search terms including SARS-COV-2, coronavirus, COVID-19, hyposmia, anosmia, ageusia and dysgeusia. The articles included were cross sectional studies, observational studies and retrospective or prospective audits, letters to editor and short communications that included a study of a cohort of patients. Case reports, case-series and interventional studies were excluded.
DISCUSSION: A total of 16 studies were selected. Incidence of smell and taste dysfunction was higher in Europe (34 to 86%), North America (19 to 71%) and the Middle East (36 to 98%) when compared to the Asian cohorts (11 to 15%) in COVID-19 positive patients. Incidence of smell and taste dysfunction in COVID-19 negative patients was low in comparison (12 to 27%). Total incidence of smell and taste dysfunction from COVID-19 positive and negative patients from seven studies was 20% and 10% respectively. Symptoms may appear just before, concomitantly, or immediately after the onset of the usual symptoms. Occurs predominantly in females. When occurring immediately after the onset of the usual symptoms, the median time of onset was 3.3 to 4.4 days. Symptoms persist for a period of seven to 14 days. Patients with smell and taste dysfunction were reported to have a six to ten-fold odds of having COVID-19.
CONCLUSION: Smell and taste dysfunction has a high incidence in Europe, North America, and the Middle East. The incidence was lower in the Asia region. It is a strong risk factor for COVID-19. It may be the only symptom and should be added to the list of symptoms when screening for COVID- 19.
