Proper driving requires a proper posture to bring comfort to drivers. A problem that commonly exists in driving is incorrect driving posture which can cause discomfort to the driver, especially when interacting with automotive pedals. Research on contraction of tibialis anterior (TA) muscle on driver's posture based on the knee angle less than 101º in a position of pressing and releasing a pedal was conducted to investigate and overcome this problem. This is a field experiment study and surface electromyography (sEMG) is used in collecting data on the TA muscle. The procedure of collecting data on the TA muscle before and after experiments follows the Surface ElectroMyoGraphy for the Non-Invasive Assessment of Muscles (SENIAM) recommendations. The result of the experiment shows that there is a strong negative relationship between driver's postures in nature based on the angle of the knee with TA muscle contractions, where the Pearson correlation coefficient (r) is - .993. While the temporal analysis measurements based on Maximum Voluntary Isometric Contraction (MVIC) 60% in a position of releasing a pedal exceeding rms µV 39.38, are 39.71 and 40.25 respectively. On the other hand, MVIC 2% rms µV values: 1.19 and 1.2 are obtained in the position of pressing the pedal. The knee angle with TA muscle contractions is significant [F (1, 10) = 660, p<.05] contributing 98.5% variance (R2 = .985) in the driver's posture. A linear equations model has been developed to clearly illustrate the result. In conclusion, when the knee angle of the driver's posture is increased, the TA muscle contraction is decreased. The increase in the knee angle will directly provide comfort to the driver while interacting with the pedal; and this is due to the reduction of TA muscle contractions.

BACKGROUND: Patients having unilateral breast reconstruction often require a second stage procedure on the contralateral breast to improve symmetry. In order to provide immediate symmetry and minimize the frequency and extent of secondary procedures, we began performing simultaneous contralateral balancing operations at the time of initial reconstruction. This study examines the indications, safety, and efficacy of this approach. METHODS: One-hundred and two consecutive breast reconstructions with simultaneous contralateral balancing procedures were identified. Data included patient age, body mass index (BMI), type of reconstruction and balancing procedure, specimen weight, transfusion requirement, complications and additional surgery under anesthesia. Unpaired t-tests were used to compare BMI, specimen weight and need for non-autologous transfusion. RESULTS: Average patient age was 48 years. The majority had autologous tissue-only reconstructions (94%) and the rest prosthesis-based reconstructions (6%). Balancing procedures included reduction mammoplasty (50%), mastopexy (49%), and augmentation mammoplasty (1%). Average BMI was 27 and average reduction specimen was 340 grams. Non-autologous blood transfusion rate was 9%. There was no relationship between BMI or reduction specimen weight and need for transfusion. We performed secondary surgery in 24% of the autologous group and 100% of the prosthesis group. Revision rate for symmetry was 13% in the autologous group and 17% in the prosthesis group. CONCLUSIONS: Performing balancing at the time of breast reconstruction is safe and most effective in autologous reconstructions, where 87% did not require a second operation for symmetry.

OBJECTIVES: To determine the factors related to spontaneous passage of ingested coins in children.

METHODS:
Design: Retrospective study

Setting: Tertiary Government Hospital

Subjects: The records of 136 pediatric patients with a history of coin ingestion seen at the emergency room department of our institution between December  2012 and May 2014 were retrospectively reviewed. Demographic data such as age and gender of the patient were recorded, including the type of coin, location of coin in the esophagus, time of ingestion and time of spontaneous passage into the stomach (for those that passed spontaneously).

RESULTS: Spontaneous passage in 27 out of 136 pediatric patients with radiographic evidence of a round radio-opaque foreign body initially located in the esophagus eventually passed into the stomach or intestines, accounting for 20% of the total number of cases. Coin ingestion was more common in patients aged 5 to 6 years (33% of cases), with slight male predominance (58%). One peso coins were the most common type of coin ingested, however only 24% of these spontaneously passed. The rate of spontaneous passage was highest in smaller sized coins (5 and 25 centavo coin) compared to larger sized coins (5 peso). Proximally located coins, albeit more common than middle and distally located coins, were the least likely to spontaneously pass (12%). Average time interval from ingestion to passage of the coin was 12 hours.

CONCLUSION: Many factors are related to spontaneous passage of foreign bodies in the esophagus. The age of the patient, type of coin ingested, and initial location of the coin in the esophagus should be considered. Older patients, smaller sized coins, and distally located coins have the highest probability of spontaneous passage beyond the esophagus. A 12-hour observation period may be considered in patients with single esophageal coin ingestion.

INTRODUCTION: Psychiatric comorbidity is common in patients with functional dyspepsia (FD) but a good screening tool for psychiatric disorders in gastrointestinal clinical practice is lacking. Aims: 1) Evaluate the performance and optimal cut-off of 12-item General Health Questionnaire (GHQ-12) as a screening tool for psychiatric disorders in FD patients; 2) Compare health-related quality of life (HRQoL) in FD patients with and without psychiatric comorbidities. METHODS: Consecutive patients fulfilling Rome III criteria for FD without medical co-morbidities and gastroesophageal reflux disease were recruited in a gastroenterology clinic. The followings were conducted at 4 weeks after index oesophagogastroduodenoscopy: self-administrated questionnaires on socio-demographics, dyspeptic symptom severity (4-point Likert scale), GHQ-12, and 36-item short-form health survey (SF-36). Psychiatric disorders were diagnosed with Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) by a trained psychiatrist, which served as reference standard. RESULTS: 55 patients underwent psychiatrist-conducted interview and questionnaire assessment. 27 (49.1%) had current psychiatric disorders as determined by SCID (anxiety disorders: 38.2%, depressive disorders: 16.4%). Receiver operating characteristic curve analysis of GHQ-12 revealed an area under curve of 0.825 (95%CI: 0.698-0.914). Cut-off of GHQ-12 at > or =3 gave a sensitivity of 63.0% (95%CI = 42.4-80.6%) and specificity of 92.9% (95%CI = 76.5%-98.9%). Subjects with co-existing psychiatric disorders scored significantly lower in multiple domains of SF-36 (mental component summary, general health, vitality and mental health). By multivariate linear regression analysis, current psychiatric morbidities (Beta = -0.396, p = 0.002) and family history of psychiatric illness (Beta = -0.299, p = 0.015) were independent risk factors for poorer mental component summary in SF-36, while dyspepsia severity was the only independent risk factor for poorer physical component summary (Beta = -0.332, p = 0.027). CONCLUSIONS: Concomitant psychiatric disorders adversely affect HRQoL in FD patients. The use of GHQ-12 as a reliable screening tool for psychiatric disorders allows early intervention and may improve clinical outcomes of these patients.

Background: Bypass, is a pattern of seeking health care outside the local community where primary health care facilities are not efficiently utilized. It is common practice for patients to go directly to secondary or tertiary health facilities for primary health concerns, causing heavy traffic at the higher level facilities and corresponding over-utilization of resources. Objective: This study aimed to determine factors associated in the bypass of health care facilities among outpatient department patients and to identify health care facility factors perceived important among patients. Method: The study employed self-administered questionnaire with the assistance of trained research assistants among patients who sought consult at the Baguio General Hospital and Medical Center Outpatient Department during the study period of August 2018 – October 2018. Respondents were asked about demographic characteristics, health insurance status, referral status, health care facility factors and answer the Personal Satisfaction Questionnaire 18 (PSQ 18) survey. Results: The questionnaire survey included 251 patients. The total rate bypassing of local health care facilities was 37.8%. Pearson chi square test revealed that educational attainment was associated with increased bypass of health care facilities (p=0.013). Factors such as age, sex, civil status, employment status, monthly income and health insurance status were significantly associated with bypass. Availability of medical doctors was the most prevelant factor in choosing a health care facility in both bypassers (36%) and non bypassers (46%). PSQ 18 survey revealed that patients are generally satisfied on the availment of health services in both bypassers (mean 3.78) and non bypassers (mean 3.89). The subscales in communication, time spent with doctor and accessibility and convenience were scored highest while technical quality was scored lowest on both groups. Conclusion Bypass of local health care facilities is a major health concern. Travelling longer distances for health care imposes unnecessary shift of direct health care costs into indirect costs such as transport. Increasing awareness of available local health care facilities and services together with its improvement might help decrease bypass especially on patients with lower educational attainment. The referral system and network of health care providers should be reinforced for better health care service delivery, patient satisfaction and lower health care cost.

Adult degenerative scoliosis (ADS) is a coronal plane deformity often accompanied by sagittal plane malalignment. Surgical correction may involve the major and/or distally-located fractional curves (FCs). Correction of the FC has been increasingly recognized as key to ameliorating radicular pain localized to the FC levels. The present study aims to summarize the literature on the rationale for FC correction in ADS. Three databases were systematically reviewed to identify all primary studies reporting the rationale for correcting the FC in ADS. Articles were included if they were English full-text studies with primary data from ADS ( ≥ 18 years old) patients. Seventy-four articles were identified, of which 12 were included after full-text review. Findings suggest FC correction with long-segment fusion terminating at L5 increases the risk of distal junctional degeneration as compared to constructs instrumenting the sacrum. Additionally, circumferential fusion offers greater FC correction, lower reoperation risk, and shorter construct length. Minimally invasive surgery (MIS) techniques may offer effective radiographic correction and improve leg pain associated with foraminal stenosis on the FC concavity, though experiences are limited. Open surgery may be necessary to achieve adequate correction of severe, highly rigid deformities. Current data support major curve correction in ASD where the FC concavity and truncal shift are concordant, suggesting that the FC contributes to the patient’s overall deformity. Circumferential fusion and the use of kickstand rods can improve correction and enhance the stability and durability of long constructs. Last, MIS techniques show promise for milder deformities but require further investigation.
