Tracheostomy remains a topical surgical procedure. The history of tracheostomy is marked by the development of various instruments, including the three-bladed tracheostomy dilator from the middle of the 19th century. The purpose of this historical note is to recall the use of this unusual instrument.

Expressed breast milk feeding has increased substantially in the past two decades. Once used primarily for preterm infants, feeding expressed breast milk is now more common in mothers giving birth to healthy term infants. However, the effect of expressed breast milk feeding on breastfeeding duration is unclear.

To assess the association between breast milk expression practices and breastfeeding duration in women giving birth to healthy infants.

From 2017 to 2018, we recruited 821 new mothers from two public hospitals in Hong Kong. Participants were followed up at 1.5, 3, and 6 months postpartum or until they stopped breastfeeding. The proportion, type, and mode of all milk feeding were assessed at each follow-up.

At 1.5 months postpartum, 47.9%, 37.7%, and 14.4% of participants were feeding by direct breastfeeding only, mixed-mode feeding, and expressed breast milk only, respectively. Participants feeding expressed breast milk only were more likely to be supplementing with infant formula. When compared with participants who provided only direct breastfeeding, participants who gave only expressed breast milk at 1.5 months had 57% lower odds of breastfeeding continuation at three months postpartum. After stratification by infant formula supplementation, expressed breast milk feeding only at 1.5 months was associated with an increased risk of breastfeeding cessation in participants supplementing with infant formula (adjusted hazard ratio [aHR] = 1.86, 95% CI = 1.17-2.95).

In the first six months postpartum, giving only expressed breast milk is associated with early breastfeeding cessation, especially in participants who are also supplementing with infant formula.

The rotation includes time on an interdisciplinary inpatient consultative palliative care service as well as time in the outpatient clinic and in the operating room with the Surgical Palliative Care attending. Most patients who are seen and evaluated have surgical issues, allowing exposure to the fundamental aspects of palliative care as they pertain to surgical practice across the continuum of healthcare settings. Communication around serious illness, complicated decision making, complex pain and symptom management, withdrawal of life-sustaining treatment, and end-of-life care are all integral parts of the rotation. The rotation has been very favorably received by the residents, and the impact on the culture of the department has been tremendous as well. The structured approach provided, including goals and objectives and the weekly schedule, make this rotation easily replicable in other residency programs.

Compare three methods of obtaining linear left ventricular dimensions within the same Doberman Pinscher (DP).

One hundred and thirty-nine client-owned DP.

Linear left ventricular dimensions were measured using two-dimensional short-axis (Sx-2D), motion-mode short-axis (Sx-MM), and motion-mode long-axis (Lx-MM) methods, then left ventricular volumes were obtained using monoplane Simpson’s method of discs (SMOD). A Friedman test with Dunn’s multiple comparisons was used to compare differences between methods. Bias and correlation were evaluated via Bland-Altman and Spearman’s correlation. Sensitivity and specificity for diagnosing occult dilated cardiomyopathy (DCM) compared to SMOD were determined. buy Amcenestrant Coefficients of variation (CVs) were calculated for intra- and inter-observer measurement variability.

There were significant differences between all linear dimensions in diastole and systole. Short-axis 2D measurements had significant bias compared with Sx-MM (diastole +1.19mm, systole +1.65mm) and Lx-MM (diastole +4.36mm, systole +3.87mm) as did Sx-MM compared with Lx-MM (diastole +3.17mm, systole +2.22mm). All linear dimensions had a moderate positive correlation with SMOD. The sensitivity and specificity of linear measurements to detect DCM were Sx-2D (sensitivity 72.0%, specificity 88.5%), Sx-MM (sensitivity 52.0%, specificity 92.0%), and Lx-MM (sensitivity 37.5%, specificity 99.1%). All methods had acceptably low CV for intra- and inter-observer measurement variability.

Results of this study suggest that linear measurements are repeatable and correlate with reference standard; however, there is a significant bias between measurements, and they should not be used interchangeably.

From January 2015 to January 2018, 90 adolescents with axillary bromhidrosis were recruited and randomly divided into three groups (group A, B, and C). Patients in group A underwent electrocauterization after removal of apocrine sweat glands, patients in group B received ultrasound-guided BOTOX injection, and patients in group C had electrocauterization after the removal of apocrine sweat glands followed by ultrasound-guided BOTOX administration after two weeks. All patients were followed up for one year. The percentages of axillary malodor score at twelve months after treatments compared with pre-operation for group A, group B, and group C were 20.2%, 27.5%, and 12.5%, respectively. Significant statistical differences were observed in changes of axillary malodor score among the three groups at three, six, nine and twelve months postoperatively.
