BACKGROUND
Mohs micrographic surgery (MMS) is the preferred surgical procedure for non melanoma skin cancers (NMSCs), especially in areas where function and cosmesis are critical. It allows precise removal of the tumor while preserving normal skin tissue.
OBJECTIVESThis study aimed to describe the clinicohistopathologic profile of patients who underwent MMS at the Dermatology Center of the St. Luke’s Medical Center, Quezon City, Philippines (SLMC-QC) from March 2003 to March 2023.
METHODSThis was a descriptive cross-sectional study utilizing a 20-year chart review on all patients who underwent MMS at SLMC-QC from March 2003 to March 2023. Data collected were the following: age, sex, race, clinicopathologic diagnosis, tumor site, pre-operative and post-operative area size, number of MMS stages, type of repair performed, and recurrence, if any.
RESULTSIn 20 years, there were a total of 684 cases done in the Dermatology Center SLMC-QC, and 573 cases with complete data were included. Eighty six percent of patients were over 50 years old. There was a slight male predominance, and most patients were Asians, followed by Caucasians. Basal cell carcinoma was the most common diagnosis followed by squamous cell carcinoma and Bowen’s disease. Majority of the tumors were located on the head and neck. The postoperative defect increased by 2-to-3-fold from the preoperative tumor size in most cases. Most tumors were cleared in 2 stages. The most common type of repair done was flaps, followed by full-thickness skin grafts and primary closures. All primary tumors treated in the center have not recurred within 5 years, bringing the cure rate to 100%.
CONCLUSIONThe clinicohistopathologic profiles of patients in this study are similar to those reported in the literature. No recurrence has been reported in the center and this reflects the effectivity of MMS.

INTRODUCTIONThe poststroke acute and rehabilitation length of stay (LOS) are key markers of stroke care efficiency. This study aimed to describe the characteristics and identify the predictors of poststroke acute, rehabilitation and total LOS. This study also defined a subgroup of patients as "short" LOS and compared its complication rates and functional outcomes in rehabilitation with a "long" acute LOS group.
MATERIALS AND METHODSA prospective cohort study (n = 1277) was conducted in a dedicated rehabilitation unit within a tertiary academic acute hospital over a 5-year period between 2004 and 2009. The functional independence measure (FIM) was the primary functional outcome measure in the rehabilitation phase. A group with an acute LOS of less than 7 days was defined as "short" acute LOS.
RESULTSIschaemic strokes comprised 1019 (80%) of the cohort while the rest were haemorrhagic strokes. The mean acute and rehabilitation LOS were 9 ± 7 days and 18 ± 10 days, respectively. Haemorrhagic strokes and anterior circulation infarcts had significantly longer acute, rehabilitation and total LOS compared to posterior circulation and lacunar infarcts. The acute, rehabilitation and total LOS were significantly shorter for stroke admissions after 2007. There was poor correlation (r = 0.12) between the acute and rehabilitation LOS. In multivariate analyses, stroke type was strongly associated with acute LOS, while rehabilitation admission FIM scores were significantly associated with rehabilitation LOS. Patients in the short acute LOS group had fewer medical complications and similar FIM efficacies compared to the longer acute LOS group.
CONCLUSIONConsideration for stroke type and initial functional status will facilitate programme planning that has a better estimation of the LOS duration, allowing for more equitable resource distribution across the inpatient stroke continuum. We advocate earlier transfers of appropriate patients to rehabilitation units as this ensures rehabilitation efficacy is maintained while the development of medical complications is potentially minimised.

Background:
Cardiovascular disease causes significant morbidity and mortality in patients with glomerulonephritis, which is increasingly diagnosed in older individuals who may have diabetes mellitus (DM). We evaluated the impact of DM on metabolic profile, renal and cardiovascular outcomes during treatment and follow-up of individuals with glomerulonephritis.
Methods:
We performed a retrospective cohort study of 601 consecutive adults with biopsy-proven glomerulonephritis for factors associated with kidney failure, hospitalization for cardiovascular events, and death. Biopsies with isolated diabetic nephropathy were excluded.
Results:
The median patient age was 49.8 years (36.7–60.9 years) with estimated glomerular filtration rate of 56.7 mL/min/1.73 m2 (27.7–93.2 mL/min/1.73 m2). DM was present in 25.4%. The most frequent diagnoses were minimal change disease (MCD) or focal segmental glomerulosclerosis (FSGS) (29.5%), lupus nephritis (21.3%), immunoglobulin A (IgA) nephropathy (19.1%), and membranous nephropathy (12.1%). The median follow-up was 38.8 months (interquartile range [IQR], 26.8–55.8 months). Among 511 individuals with lupus nephritis, anti-neutrophil cytoplasmic antibody-associated vasculitis, MCD/FSGS, membranous nephropathy, and IgA nephropathy, 52 (10.2%) developed kidney failure at a median 16.4 months (IQR, 2.3–32.2 months), while 29 (5.7%) had cardiovascular-related hospitalizations at 12.9 months (IQR, 4.8–31.8 months) and 31 (6.1%) died at 13.5 months (IQR, 2.5–42.9 months) after diagnosis. Cox regression analysis found that baseline DM was independently associated with kidney failure (adjusted hazard ratio [HR], 2.07; 95% confidence interval [CI], 1.06–4.05, p = 0.03) and cardiovascular-related hospitalization (adjusted HR, 2.69; 95% CI, 1.21–5.98, p = 0.02) but not with mortality.
Conclusion
DM was strongly associated with kidney failure and hospitalization for cardiovascular events in patients with biopsy-proven glomerulonephritis.

INTRODUCTIONMore than half of all deaths in Singapore occur in hospitals. Little is known about the quality of care received by dying patients in hospitals. The Liverpool Care Pathway (LCP) provides a framework of providing good end-of-life care for dying patients and has been used with success in the United Kingdom (UK). In this study, we investigate whether adoption of a modified LCP in a Singapore hospital translated to better end-of-life care for cancer patients.
MATERIALS AND METHODSThe LCP was adapted and implemented as a pilot project on an oncology ward in Singapore General Hospital. A baseline review of 30 consecutive death records was performed, followed by a 4-month pilot and post-implementation audit of 30 consecutive patients on the adapted LCP.
RESULTSFive types of end-of-life symptoms were analysed. There was only 1 uncontrolled symptom at death in the post-implementation group compared to 24 uncontrolled symptoms in the retrospective audit group. The prescription of breakthrough medications for symptom control increased from 21% in the retrospective audit group to 79% in the post-implementation group. Inappropriate monitoring was discontinued in 25 patients in the post-implementation group compared to none in the retrospective audit group. The documentation of resuscitation status and religion of the patient was improved, achieving full documentation in the post-implementation group.
CONCLUSIONThis study shows promising results for improving end-of-life care in cancer patients with a protocol-based pathway in a Singapore hospital. Extension of this care pathway to other settings should be explored to maximise its benefits to patients dying from all causes in hospital.

BACKGROUND
Seborrheic keratosis is a common benign skin tumor treated with invasive methods like electrodessication, cryotherapy, or surgery. Topical therapy with trichloroacetic acid (TCA) may be a cheaper, non-invasive alternative with less complications. While TCA has been studied for other skin conditions, more research is needed on its use for seborrheic keratosis.
OBJECTIVETo compare the safety and efficacy of one time application of 80% TCA peel to 65% TCA peel in the clearance of raised seborrheic keratosis in Filipino patients.
METHODOLOGYOne hundred one patients were randomized to either 80% or 65% TCA groups. Each participant underwent one session of treatment and was followed up after a month. Pre- and post-test size and thickness of lesions were compared between groups.
RESULTSBased on Physician’s Lesion Assessment (PLA), both concentrations of TCA achieved high treatment success (TCA80: 66.7%, TCA65: 68%, p-value 0.89). A similar trend was observed based on Subject’s Self-Assessment (TCA80: 74%, TCA65: 74.5%, p-value 0.95). Similar reductions in lesion size and thickness were observed in both concentrations. In terms of safety, pain, pruritus, and erythema were mostly observed during and immediately after treatment, with little to no adverse events observed after 1 month in both groups.
CONCLUSIONOne time application of either 80% or 65% TCA is effective in decreasing the size and thickness of seborrheic keratosis with little to no complications 1 month post- treatment. Both concentrations were safe, causing minimal and non-persistent pain, pruritus, and erythema immediately after application.

INTRODUCTIONLittle data is available on community hospital admissions. We examined the differences between community hospitals and the annual trends in sociodemographic characteristics of all patient admissions in Singaporean community hospitals over a 10- year period from 1996 to 2005.
MATERIALS AND METHODSData were manually extracted from medical records of 4 community hospitals existent in Singapore from 1996 to 2005. Nineteen thousand and three hundred and sixty patient records were examined. Chisquare test was used for univariate analysis of categorical variables by type of community hospitals. For annual trends, test for linear by linear association was used. ANOVA was used to generate beta coefficients for continuous variables.
RESULTSMean age of all patient admissions has increased from 72.8 years in 1996 to 74.8 years in 2005. The majority was Chinese (88.4%), and female (58.1%) and admissions were mainly for rehabilitation (88.0%). Almost one third had foreign domestic workers as primary caregivers and most (73.5%) were discharged to their own home. There were significant differences in socio-demographic profile of admissions between hospitals with one hospital having more patients with poor social support. Over the 10-year period, the geometric mean length of stay decreased from 29.7 days (95% CI, 6.4 to 138.0) to 26.7 days (95% CI, 7.5 to 94.2), and both mean admission and discharge Barthel Index scores increased from 41.0 (SD = 24.9) and 51.8 (SD = 30.0), respectively in 1996 to 48.4 (SD = 24.5) and 64.2 (SD = 27.3) respectively in 2005.
CONCLUSIONThere are significant differences in socio-demographic characteristics and clinical profile of admissions between various community hospitals and across time. Understanding these differences and trends in admission profiles may help in projecting future healthcare service needs.

Ma. Celina Cephyr C. Gonzalez ; Veronica Marie E. Ramos ; Cynthia P. Ciriaco-Tan
Acta Medica Philippina 2020;54(3):305-312
Background:
Seborrheic keratosis is a benign skin tumor removed through electrodessication, cryotherapy, or surgery. Alternative options may be beneficial to patients with contraindications to standard treatment, or those who prefer a non-invasive approach.
Objectives:
To determine the effectiveness and safety of topical medications on seborrheic keratosis in the clearance of lesions, compared to placebo or standard therapy.
Methods:
Studies involving seborrheic keratosis treated with any topical medication, compared to cryotherapy, electrodessication or placebo were obtained from MEDLINE, HERDIN, and Cochrane electronic databases from 1990 to June 2018.
Results:
The search strategy yielded sixty articles. Nine publications (two randomized controlled trials, two non-randomized controlled trials, three cohort studies, two case reports) covering twelve medications (hydrogen peroxide, tacalcitol, calcipotriol, maxacalcitol, ammonium lactate, tazarotene, imiquimod, trichloroacetic acid, urea, nitric-zinc oxide, potassium dobesilate, 5-fluorouracil) were identified. The analysis showed that hydrogen peroxide 40% presented the highest level of evidence and was significantly more effective in the clearance of lesions compared to placebo.
Conclusion
Most of the treatments reviewed resulted in good to excellent lesion clearance, with a few well-tolerated minor adverse events. Topical therapy is a viable option; however, the level of evidence is low. Standard invasive therapy remains to be the more acceptable modality.

BACKGROUND AND OBJECTIVES
The Department of Clinical Epidemiology (DCE) of the University of the Philippines Manila is the only higher education institution in the Philippines offering graduate studies in clinical epidemiology. The Master of Science Epidemiology (Clinical Epidemiology) was first offered in 1992, while the Diploma in Epidemiology (Clinical Epidemiology) was offered in 1998. While the courses of the programs are continuously updated based on students’ feedback and advances on topics covered, the point of view of the students and alumni on the program as a whole has not been done. This study aimed to determine 1) self-reported current positions and affiliations, work areas where clinical epidemiology (CE) training is useful, and skills gained from CE training; 2) research studies completed and deemed by respondents to have considerable impact; and 3) strengths, weaknesses, and areas of improvement of the DCE graduate programs.
METHODSThis is an online survey of students and alumni of the DCE graduate programs. We sent email invites to all 287 students and alumni. We collected data on their profession, institutional affiliations, positions, skills gained from their training, areas of clinical epidemiology applications, important research involvement, reasons for recommending or not recommending the programs, and how the graduate programs can be improved. Responses were summarized by frequencies and percentages. An analyst performed qualitative content analysis (QCA) to generate strengths and weaknesses of the program. We validated the results of the QCA through 1) presentation to the research team, 2) sending the survey report to study participants and other students and alumni for feedback, and 3) presentation to the DCE faculty and staff.
RESULTSWe received 159 responses (55.4% of the total study population)—145 (91.2%) were from the MSc program and 11 (6.9%) were from the Diploma program. Majority of the respondents were physicians (93.7%), had hospital affiliations (81.8%), and were affiliated with the academe (61%). Majority of the respondents used clinical epidemiology in their research endeavors (87.4%), clinical practice (85.5%), and teaching (78%). Majority (93.1%) would recommend the program they have taken. Eleven (6.9%) respondents were hesitant due to the possible mismatch with the students’ career path, challenging thesis work, and potential conflicting personal responsibilities. Several strengths of the programs were identified, including excellent and well-implemented programs, supportive faculty and staff, and relevant course work. While completing the course work had not been a problem in general, the main challenge encountered by students is the completion of their thesis, leading to a low graduation rate in the Master of Science program. Suggestions to improve the Master of Science and Diploma programs include 1) Improvement in program implementation, including thesis policies and support, smoother transition from Diploma to MSc Program and vice-versa, and implementation of a blended learning platform; 2) Curricular improvements such as wider choices for electives and tracking towards specialty areas; 3) Innovations in conduct of courses; and 4) Personnel and infrastructure development.
CONCLUSIONThis survey reiterated the importance of clinical epidemiology graduate programs in research capacity building of health care professionals. Students and alumni occupied diverse positions in academic, research, clinical, and pharmaceutical setting, and majority accomplished research studies with considerable impact. A major challenge leading to a low graduation rate in the Master of Science program is the completion of thesis work. The survey identified several initiatives towards continuous quality improvement of clinical epidemiology programs, including improvement of thesis policies and support, updating the curriculum content and materials, increasing allotment of hours for hands-on activities, exploring possibilities of offering electives in partnership with other institutions, offering a blended learning platform, maintaining an efficient administrative support for students, and continuing education for alumni. Strong institutional support for personnel and infrastructure development is essential for these initiatives to succeed.
