INTRODUCTION

The sudden designation as a COVID-19 Referral Center at the beginning of the pandemic brought about immense change to the Cardiac Catheterization Laboratory (CCL) services of a National Referral Center for tertiary care. As a proactive strategy to determine actions that can be undertaken should an unforeseen event ever happen again, this study was done to explore the impact of COVID-19 to the institution’s CCL caseload, and to review the challenges, innovations and adjustments made by the CCL to become pandemic-capable and crisis-ready.

A qualitative cross-sectional study was conducted, with the first phase describing the CCL census starting from the baseline pre-COVID year of 2019 to the pandemic years of 2020-2022, and the second phase involving Key Informant Interviews (KII) and Focus Group Discussion (FGD) with the hospital and CCL healthcare staff.

The study revealed a large reduction in the urgent, elective and overall number of cases of the CCL in the first year, but has seen a steady increase in subsequent years. Surges of COVID variants were also seen to affect the CCL caseload. The following were noted to be the key elements in the CCL’s transformation to become COVID-19 capable: (a) changes in operations and patient selection, (b) appropriate use of PPE, (c) strict adherence to an infection control protocol, and (d) staffing modifications to reduce infectivity and protect staff availability.

The preparation of the hospital’s CCL to become a pandemic capable laboratory has been difficult and faced many challenges. However, the innovations and adjustments done through efforts and ingenuity of the CCL healthcare team allowed continuous delivery of the highest level of care to patients in spite of the changing pandemic landscape. These changes were duly documented as a basis for response to possible future global and/or national healthcare crises.

Occupational lung diseases (OLD) are a group of preventable conditions caused by noxious inhalation exposure in the workplace. Workers in various industries are at a higher risk of developing OLD. Despite regulations contributing to a decreased incidence, OLD remain among the most frequently diagnosed work-related conditions, contributing to significant morbidity and mortality. A multidisciplinary discussion (MDD) is necessary for a timely diagnosis. Imaging, particularly computed tomography, plays a central role in diagnosing OLD and excluding other inhalational lung diseases. OLD can be broadly classified into fibrotic and non-fibrotic forms. Imaging reflects variable degrees of inflammation and fibrosis involving the airways, parenchyma, and pleura. Common manifestations include classical pneumoconioses, chronic granulomatous diseases (CGD), and small and large airway diseases. Imaging is influenced by the type of inciting exposure. The findings of airway disease may be subtle or solely uncovered upon expiration. High-resolution chest CT, including expiratory-phase imaging, should be performed in all patients with suspected OLD. Radiologists should familiarize themselves with these imaging features to improve diagnostic accuracy.

Laparoscopic anterior lumbar interbody fusion (L-ALIF), which employs laparoscopic cameras to facilitate a less invasive approach, originally gained traction during the 1990s but has subsequently fallen out of favor. As the envelope for endoscopic approaches continues to be pushed, a recurrence of interest in laparoscopic and/or endoscopic anterior approaches seems possible. Therefore, evaluating the current evidence base in regard to this approach is of much clinical relevance. To this end, a systematic literature search was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using the following keywords: “(laparoscopic OR endoscopic) AND (anterior AND lumbar).” Out of the 441 articles retrieved, 22 were selected for quantitative analysis. The primary outcome of interest was the radiographic fusion rate. The secondary outcome was the incidence of perioperative complications. Meta-analysis was performed using RStudio’s “metafor” package. Of the 1,079 included patients (mean age, 41.8±2.9 years), 481 were males (44.6%). The most common indication for L-ALIF surgery was degenerative disk disease (reported by 18 studies, 81.8%). The mean follow-up duration was 18.8±11.2 months (range, 6–43 months). The pooled fusion rate was 78.9% (95% confidence interval [CI], 68.9–90.4). Complications occurred in 19.2% (95% CI, 13.4–27.4) of L-ALIF cases. Additionally, 7.2% (95% CI, 4.6–11.4) of patients required conversion from L-ALIF to open surgery. Although L-ALIF does not appear to be supported by studies available in the literature, it is important to consider the context from which these results have been obtained. Even if these results are taken at face value, the failure of endoscopy to have a role in the ALIF approach does not mean that it should not be incorporated in posterior approaches.

Background: The established recommendations and guidelines regarding ideal measurements for an attractive face are mostly based on data gathered among Caucasian population. The aim of this study was to examine the relationship between perception of 3-dimensional facial attractiveness and golden ratio, neoclassical canons, ‘ideal’ ratios and ‘ideal’ angles in Hong Kong Chinese. Methods: Thirty 3-D photographs (15 males and 15 females) were shown to 101 laypersons and 60 patients seeking orthognathic treatment. The photographs were rated based on a 100 mm visual analogue scale (VAS) from 0 (very unattractive) to 100 (very attractive). Results: More than half of the measurements (42/77) in females and thirty-two measurements in males were found to be significantly different from the ideal target value (p < 0.05) upon the comparison of the attractive faces with golden ratio, neoclassical canons, ‘ideal’ ratios and ‘ideal’ angles. Meanwhile, correlation tests between VAS scores and the parameters detected significant results (p < 0.05) in only six ratios, eight angles, one neoclassical canon and one proportion. Conclusions Despite several renowned ‘ideal’ parameters of attractive faces that have been recommended in the literature, only a few of them were found to be significantly correlated with attractive faces in Hong Kong Chinese.

Objectives: This study aims to determine the diagnostic yield and safety of sputum induction with hypertonic saline in the microbiologic confirmation of childhood tuberculosis (TB) in a tertiary hospital in the Philippines.

Methods: This is a randomized controlled trial with an interrupted time series in the control group. One hundred twelve (112) pediatric patients (4-18 years old) with clinical findings suggestive of TB were enrolled in the study. Patients were randomized into two groups composed of 56 patients each. Group A patients underwent sputum induction. Group B patients underwent spontaneous expectoration followed by sputum induction. The microbiologic yield for acid-fast bacilli and TB culture were determined and analyzed.

Results: Among the patients randomized to Group A, microbiologic confirmation for TB was 8/56 patients (14.3%) after sputum induction. For patients randomized to Group B, microbiologic yield was 4/56 patients (7.1%) from spontaneous expectoration; after sputum induction, the microbiologic yield increased to 5/56 patients (8.9%). There is insufficient evidence of statistical significance in microbiologic yield on parallel analysis of the two separate groups (p=0.22). Furthermore, for patients randomized to Group B, the increase in microbiologic yield after sputum induction compared to spontaneous expectoration did not reach statistical significance (p=1.000). The procedure was well-tolerated among children; no serious adverse events were observed.

Conclusion: Sputum induction is a feasible and safe method of specimen collection for microbiologic diagnosis of TB among children. While the microbiologic yield increased after sputum induction compared to spontaneous expectoration, the additional yield does not seem to be significant.

Background: Periocular dark circles (PDCs) are a common cosmetic complaint. Grading systems based on objective measures have been used but no standard system is in place. Objective: To determine factors associated with subjective and objective PDC severity. Methods: Enrolled patients (n=100) completed a questionnaire comprised of demographic variables, medical history, and self-perception of PDC. Those perceiving PDC graded dissatisfaction on a 10-point scale. Clinical severity (grades 0∼4) and subtype (constitutional, post-inflammatory, vascular, shadow effects, or others) were determined. A Konica Minolta CR-400 chromameter was used to obtain colorimetry measurements (L*a*b* values). The objective average difference in darkness (ΔL*) between the periocular region and the cheek was determined. Comparisons were made using Spearman correlation coefficients (r). Results: Patient dissatisfaction correlated with both clinical severity (r=0.46,p＜0.001) and the ΔL* by colorimetry (r=0.35, p=0.004). Factors associated with subjective dissatisfaction were female sex (r=0.38, p=0.002), higher Fitzpatrick skin type (r=0.42, p=0.001), fewer hours of sleep (r=–0.28, p=0.03), and use of concealer (r=0.35, p=0.004). Factors associated with objective measures were higher Fitzpatrick skin type (r=0.36, p= 0.0007 and r=0.28, p=0.009, respectively), family history of PDC (r=0.34, p＜0.001 and r=0.20, p=0.05), and history of eczema (r=0.45, p＜0.001 and r=0.20, p=0.0504). Clinical severity grading correlated with colorimetric severity (r=0.36, p=0.0003). Conclusion Overall, subjective dissatisfaction was associated with clinical severity. However, factors associated with subjective severity did not necessarily overlap with factors associated with objective severity. These findings highlight the importance of patient-reported grading. There may be added value in incorporating a component of subjective grading into the traditionally objective PDC grading scales.
