Abstract Purpose Postoperative bleeding after thyroid surgery remains a potentially lethal complication. Outpatient thyroidectomy is an increasing trend in the high volume centers. There is a need to identify risk factors for postoperative bleeding in order to select proper patients for outpatient thyroidectomy. This study aimed to investigate this issue using a national population-based register. Material and method A nested case-control study on patients registered in the Swedish national register for endocrine surgery (SQRTPA) was performed. Patients with postoperative bleeding were matched 1:1 by age and gender to controls. Additional information on cases and controls was obtained from attending surgeons using a questionnaire. Risk factors for postoperative bleeding were evaluated with logistic regression and are presented as odds ratios (ORs) with 95% confidence intervals (CIs). The time of bleeding in relation to surgery was also investigated. Results There were 9494 operations, and 174 (1.8%) of them involved postoperative bleeding. In the whole cohort, patients with postoperative bleeding were older, 58 (46–69) vs. 49 (37–62) years, than patients without, p < 0.01. Male patients had a higher risk of bleeding, OR 2.18 (95% CI 1.58–2.99). In the case-control cohort, drain was an independent risk factor for bleeding, OR 1.64 (1.05–2.57). Two-thirds of patients bled within 6 h after surgery. The incidence of bleeding after 24 h was 10%. Conclusion High age, male gender, and drain are independent risk factors for bleeding after thyroid surgery. Even with careful patient selection, prolonged observation might be necessary in thyroid surgery.

ABSTRACT Aims and objectives The study determined the relationship between chronic kidney disease (CKD) and changes in salivary flow and the complications of reduced salivary flow among African subjects with CKD compared with the controls. Materials and methods One hundred and eighty patients, 90 CKD and 90 controls were recruited, interviewed and examined. Stimulated and unstimulated saliva collection was done with standardized spitting method. Urinalysis and blood creatinine levels were determined and glomerular filtration rate (GFR) of each patient was calculated from the blood creatinine using Cockcroft and Gault formula. Statistical analysis was done using STATA 11 software. Results The mean stimulated and unstimulated whole salivary flow rate among CKD subjects were 4.07 ± 1.91 and 2.34 ± 0.99 ml/5 min respectively and is significantly lower than that of the controls which were 8.05 ± 3.95 ml/5 min and 3.82 ± 2.27 ml/5 min for stimulated and unstimulated flow rates. Oral signs of reduced salivary flow were found in 80% of CKD patients. The commonest oral finding was taste abnormalities others are burning sensation, halitosis and difficulty in mastication. Conclusion Patients with CKD had reduced stimulated and unstimulated salivary flow rate. Reduced salivary flow was associated with oral lesions in majority (80%) of CKD patients, the commonest finding being taste abnormalities.

Background: Several studies have investigated the differences in salivary parameters and microbial composition between diabetic and non-diabetic patients, however, specific differences are still not clear mainly due to the effects of confounder. Aim: The aim of this case-control study was to evaluate the salivary and microbial parameters of chronic periodontitis subjects with and without type 2 diabetes mellitus. Material and method: This case-control study included 60 chronic periodontitis subjects, 30 diabetics (case group) and 30 non-diabetics (control group), paired according to periodontitis severity, gender and age. Stimulated whole saliva was collected from all volunteers to measure the salivary pH and the salivary flow rate. Bacterial samples were collected with paper points from periodontal sites showing the deepest periodontal pocket depth associated with the highest clinical attachment loss. The frequency of A. actinomycetemcomitans, P. intermedia, P. gingivalis, T. forsythia and C. rectus was evaluated by PCR. Data was statistically analyzed by Student's t, Mann-Whitney and Chi-square (p<0.05). Result: Diabetic subjects showed higher salivary glucose levels and lower stimulated flow rates in comparison to non-diabetic controls. P. gingivalis and T. forsythia were the most frequent pathogens (p<0.05). Bacterial frequency did not differ between case and control groups. Conclusion: Diabetes status influenced salivary glucose levels and flow rate. Within the same severity of chronic periodontitis, diabetic subjects did not show higher frequency of periodontal pathogens in comparison to their paired controls.

Objective: To describe cases and timing of pediatric post-tonsillectomy hemorrhage (PTH), to evaluate predictors of PTH, and to determine the optimal amount of postoperative care unit (PACU) monitoring time. Study Design: Using the Pediatric Health Information System (PHIS) database and electronic medical records, a matched case-control study from 2005 to 2015 was performed. Setting: A single, tertiary-care institution. Subjects and Methods: Each case of PTH was matched with 1 to 4 controls for the following factors: age, sex, surgeon, and time of year. A total of 124 cases of PTH and 479 tonsillectomy controls were included. The rate and timing of postoperative bleeding were assessed, and matched pair analysis was performed using conditional logistic regression. Results: Our institutional PTH rate of 1.9% (130 of 6949) included 124 patients; 15% (19) were primary (≤24 hours), with 50% (9) occurring within 5 hours. Twenty-one percent (4 of 19) of primary PTH patients received operative intervention. Eighty-five percent (105 of 124) of all cases were secondary PTH, and 47% (49) of those patients received operative intervention. Cold steel (OR 1.9, 95% CI 1.1-3.3) and Coblation (OR 1.9, 95% CI 1.2-3.1) techniques and tonsillectomy alone (OR 3.7, 95% CI 1.9-7.2) increased odds of PTH. Patients who developed PTH had 4 times the odds of having a preceding postoperative respiratory event than controls (OR 4.0, 95% CI 1.6-10.0). Conclusion: We conducted a rigorous case-control study for PTH, finding that PTH was associated with use of cold steel and Coblation techniques and with tonsillectomy alone. Patients with a postoperative respiratory event may be more likely to develop a PTH and should be counseled accordingly. A PACU monitoring time of 4 hours is sufficient for outpatient tonsillectomy.
