Philippine Journal of Otolaryngology Head and Neck Surgery 2009;24(1):21-26
Objective: To fabricate an inexpensive, reproducible and portable ringlight with flexible, quick-release mount for use with point-and-shoot consumer digital cameras in intraoral photodocumentation. Methods: Design: Instrumentation Setting: Tertiary Care Hospital Procedure: A commercially-available battery-powered mountaineer’s LED (Light Emitting Diode) headlight was converted into a portable ringlight with a flexible, quick-releasemount for intraoral photodocumentation. Results: The Flexmount Ringlight delivered an even and white illumination of the oral cavity and oropharynx at a working distance of more than 5cm from the subject in focus. It resulted in sharper pictures due to its constant illumination that assisted the camera’s autofocus system in getting accurate focusing intraorally. It also allowed the camera to use smaller apertures that have put more elements in focus and faster shutter speeds that have markedly reduced motion blur. Conclusion: The Flexmount Ringlight is an inexpensive, easy-to-assemble and portable ringlight that can be used in point-and-shoot consumer digital cameras. Its constant and even illumination resulted in reproducible, sharp, shadowless photographs of the oral cavity and oropharynx.

Objective: To describe the clinical and demographic profile of patients who underwent pediatric Endoscopic Sinus Surgery (ESS) and the indications for which the procedure was performed. Methods: Design: Cross-sectional Study Setting: Tertiary Government Hospital Subjects: Using the medical record registry, all patients below 18 years of age who underwent ESS under the Department of Otorhinolaryngology – Head and Neck Surgery of a tertiary government hospital in Metro Manila between December 31, 1999 and January 1, 2008 were reviewed. The age, sex, clinical presentation indications for doing ESS and extent of surgery done were described. The Lund MacKay Grading for nasal polyposis and Scoring for sinusitis were also applied and cross-referenced. Results: Twenty-seven children aged 7 to 17 years underwent ESS. The mean age was 12.9 years with most (15 patients) belonging to the adolescent age group (13-17 years). Male to female ratio was 1.45:1. The mean interval from onset of symptoms to the first outpatient consultation was 1.5 years; the most common presenting symptoms were nasal obstruction (85.2%) and discharge (59.3%). All of the patients who underwent pediatric ESS had chronic rhinosinusitis: either with nasal polyposis (85.2%), an antrochoanal polyp (11.1%) or both (3.7%). The Lund Mackay Grading for nasal polyps and sinusitis scores were cross-referenced: patients with larger, grade III nasal polyps tended to have more extensive sinus disease than those with grade II polyps. On their first consultation, the patients tended to present with extensive nasal polyp and sinus disease indicating the need for surgery. All patients with CRS and nasal polyposis underwent polypectomy with ethmoidectomy, uncinectomy and maxillary antrostomy, with additional frontal sinusotomy for a 17-year-old male and a 17-year-old female, both with grade 3 polyposis. The three patients who had antrochoanal polyps underwent polypectomy with uncinectomy and maxillary antrostomy. There were no operative complications such as cerebrospinal fluid leak and orbital injury reported.

OBJECTIVE: We determined the efficacy of extracorporeal shock wave lithotripsy (ESWL) monotherapy and compared its cost-effectiveness with percutaneous nephrolithotomy (PCNL) for the management of lower pole renal calculi with a size of 1.0cm to 2.0cm in widest dimension.
MATERIALS AND METHODS: Using the cost estimate data available locally from patient billing charges and average professional fee, efficacy and complication rates data from the literature, the cost-effectiveness for the percutaneous nephrolithotomy and shock wave lithotripsy as primary therapy for lower pole stones were evaluated. We developed a decision analysis model in which a patient in whom primary therapy (either ESWL or PCNL failed was rendered stone-free with secondary ESWL using a trial version add-in software for Microsoft Excel from www.TreePlan.com with some modifications.
RESULTS: The average cost over all outcomes from the decision to perform ESWL in patients with lower pole stones 1.0 to 2.0 cm is Php 53,801.07 and Php 127,019.27 for PCNL. For PCNL to be as cost effective, cost incurred should be lowered to Php 47,746.38
CONCLUSIONS: Extracoporeal shock wave lithotripsy, despite its considerable low efficacy as compared to PCNL as a primary treatment for lower pole stones 1.0 to 2.0 cm, is still more cost-effective.

Clinics in Shoulder and Elbow 2023;26(4):455-461
Arthroscopic shoulder procedures are one of the most common procedures used to restore function through minimally invasive techniques. With the demand for shoulder arthroscopic procedures comes the need for safe, effective, and efficient surgery that maximizes patient outcomes while minimizing complications. Many variables contribute to visualization in shoulder arthroscopy including vascular anatomy, blood pressure control, arthroscopic pump systems, turbulence control, epinephrine, and tranexamic acid. Furthermore, patient positioning can have a dramatic effect on visualization with both the beach chair position and lateral decubitus positioning having various strengths and weaknesses depending on the intended procedure being performed. The purpose of this review is to examine the benefits and complications reported in the literature for improving visualization in shoulder arthroscopy.

Background:
Total elbow arthroplasty (TEA) is uncommon, but growing in incidence. Traditionally an inpatient operation, a growing number are performed outpatient, consistent with general trends in orthopedic surgery. The aim of this study was to compare TEA outcomes between inpatient and outpatient surgical settings. Secondarily, we sought to identify patient characteristics that predict the operative setting.
Methods:
Patient data were collected from the American College of Surgeons National Quality Improvement Program. Preoperative variables, including patient demographics and comorbidities, were recorded, and baseline differences were assessed via multivariate regression to predict operative setting. Multivariate regression was also used to compare postoperative complications within 30 days.
Results:
A total of 468 patients, 303 inpatient and 165 outpatient procedures, were identified for inclusion. Hypoalbuminemia (odds ratio [OR], 2.5; P=0.029), history of chronic obstructive pulmonary disorder or pneumonia (OR, 2.4; P=0.029), and diabetes mellitus (OR, 2.5; P=0.001) were significantly associated with inpatient TEA, as were greater odds of any complication (OR, 4.1; P<0.001) or adverse discharge (OR, 4.5; P<0.001) and decreased odds of reoperation (OR, 0.4; P=0.037).
Conclusions
Patients undergoing inpatient TEA are generally more comorbid, and inpatient surgery is associated with greater odds of complications and adverse discharge. However, we found higher rates of reoperation in outpatient TEA. Our findings suggest outpatient TEA is safe, although patients with a higher comorbidity burden may require inpatient surgery.Level of evidence: III.

PURPOSE: Hypersensitivity to fungi is associated with rhinoconjunctivitis and asthma. For some fungi, such as Alternaria alternata (A. alternata), the symptoms of asthma are persistent, increasing disease severity and the risk of fatal outcomes. There are a large number of species of fungi but knowledge of them remains limited. This, together with the difficulties in obtaining adequate standardized extracts, means that there remain significant challenges in the diagnosis and immunotherapy of allergy associated with fungi. The type of indoor fungi related to asthma/allergy varies according to geographic, climatic, and seasonal factors, making their study difficult. The aim of this study was to determine hypersensitivity to indoor fungi in a population from Cuenca, Spain. METHODS: Thirty-five patients with symptoms compatible with rhinitis or asthma who showed clear worsening of their symptoms in their homes or workplace were included. In vivo and in vitro tests were made with a battery of fungal allergens, including the species isolated in the home or workplace. RESULTS: Ulocladium botrytis (U. botrytis) and A. alternata were the most representative species as a source of home sensitization. These species showed very high concordance in skin tests, specific IgE, and histamine release. The allergen Alt a 1, which was recognized in all patients, was detected in A. alternata, U. botrytis, and Stemphylium botryosum (S. botryosum). CONCLUSIONS: U. botrytis and A. alternata were the most representative species as a source of home sensitization. Alt a 1 was recognized in all patients and may be considered a non-species-specific allergen that could be used as a diagnostic source of sensitization to some species of the Pleosporaceae family.

Clinical Endoscopy 2021;54(5):754-758
The Roux-en-Y gastric bypass is one of the most extensive surgical treatments for obesity. The treatment of upper gastrointestinal bleeding after Roux-en-Y gastric bypass is complex due to the difficulty of accessing the excluded gastric antrum and duodenal bulb. There is no consensus regarding the management of this complication. While various techniques have been described to access the biliopancreatic limb, double-balloon enteroscopy is the most commonly used. If double-balloon enteroscopy is unavailable, a pediatric colonoscope may be used as an alternative; however, its use in such cases has not been described. We report the case of a 50-year-old male patient who underwent gastric bypass 13 years ago and was admitted for a second episode of upper gastrointestinal bleeding. The initial approach using upper endoscopy, colonoscopy, and abdominal computed tomography angiography did not reveal the cause of gastrointestinal hemorrhage; therefore, an endoscopic study of the biliopancreatic limb was performed using a pediatric colonoscope. A Forrest Ib ulcer was found in the duodenal bulb, and endoscopic therapy was administered. The evolution was found to be satisfactory.

Salivary gland (SG) dysfunction, due to radiotherapy, disease, or aging, is a clinical manifestation that has the potential to cause severe oral and/or systemic diseases and compromise quality of life. Currently, the standard-of-care for this condition remains palliative. A variety of approaches have been employed to restore saliva production, but they have largely failed due to damage to both secretory cells and the extracellular matrix (niche). Transplantation of allogeneic cells from healthy donors has been suggested as a potential solution, but no definitive population of SG stem cells, capable of regenerating the gland, has been identified. Alternatively, mesenchymal stem cells (MSCs) are abundant, well characterized, and during SG development/homeostasis engage in signaling crosstalk with the SG epithelium. Further, the trans-differentiation potential of these cells and their ability to regenerate SG tissues have been demonstrated. However, recent findings suggest that the "immuno-privileged" status of allogeneic adult MSCs may not reflect their status post-transplantation. In contrast, autologous MSCs can be recovered from healthy tissues and do not present a challenge to the recipient's immune system. With recent advances in our ability to expand MSCs in vitro on tissue-specific matrices, autologous MSCs may offer a new therapeutic paradigm for restoration of SG function.
