While there is an ethical obligation to improve clinical outcomes by developing better therapies, surgical innovation has largely progressed without the strict regulations required of novel pharmaceutical products. We explore the reasons why new surgical techniques are frequently introduced without the benefit of randomised controlled trials, and present an approach to the ethical evaluation of novel surgical procedures.

·AIM: To assess the biocompatibility of bovine bone as orbital implants in rabbits.·METHODS: Bovine bone graft was used as an ocular implant in rabbits to determine whether it could be successfully used in the anophthalmic socket as an alternative to the expensive synthetic alloplastics. Evisceration of eyes with and without bovine bone orbital implantation was performed in the right eyes of 12 New Zealand white rabbits.Group Y (n =6) was eviscerated without implant, meanwhile Group X (n =6) was eviscerated with insertion of an orbital implant using bovine bone. Observation was carried out on day 1, day 7, day 14, day 28 and day 42. Serial clinical examination was carried out based on a few fixed criteria,which included rate of infection, implant migration, evidence of wound breakdown and any restriction of intraocular movements. The implanted eyes were then enucleated on day 42. The enucleated eyes were sent for histopathological evaluation to record the type of inflammatory reaction and rate of fibrovascular ingrowth.·RESULTS: Serial clinical examination showed presence of minimal infection in all eyes, both in Group X implanted) and Group Y (control) on first postoperative day, which responded well with antibiotics. Infection occurred in the implanted group after first postoperative day, but there was no evidence of orbital migration or extrusion of implant, wound breakdown, restriction of extraocular movement, severe infection or any physical abnormality. Histopathological examination revealed good fibrovascular ingrowth in the implanted group, with minimal rejecting reaction of rabbit eye towards bovine bone implant.·CONCLUSION: This study shows that bovine orbital implant has a good biocompatibility in rabbit eyes and its cost is acceptable.

We report a case of a healthy 78 -year- old indonesian man who presented with chronic weight loss, poor appetite and lethargy. CT abdomen showed bilateral adrenal masses. EUS – guided FNA was performed on the left adrenal gland. Histopathology report was Histoplasma Capsulatum. He recovered well with antifungal treatment without any complication. In this case, we found that the role of EUS – guided FNA was not only limited to diagnosis but also helped in the prognosis of the disease since the method was able to assess the general anatomy of the adrenal gland better than other imaging modalities due to its close proximity and direct visualization.

A 26 year-old Malay man presented with first attack of left eye optic neuritis that recovered fully with intravenous methylprednisolone after 3 weeks. He developed a second attack of optic neuritis in the right eye the following week. Lhermitte sign as well as Uthoff phenomenon were also positive. On day-3, he developed bilateral paraplegia and sensory loss at T8 level, which progressively worsen and became bedridden on day-5. MRI showed bilateral enhance-ment of the optic nerve with the presence of long multisegmental demyelinating plaque in the thoracic to lumbar spinal cord and the brainstem, sparing the brain hemisphere. He was promptly given high dose intravenous methylprednisolone followed by oral predni-solone. He was also assigned on intensive neuro-phy-siotherapy. He recovered after 3 months and was able to walk with walking aids. He recovered completely after 7 months and resumed working as site contactor. There was no relapse during the last 1 year follow-up. His final visual acuity improved to 6/9 in the right eye and 6/6 in the left eye. The visual field of the right eye showed per-sistent mild cecocentral scotoma. And diffuse depression.

BACKGROUND: The long term complications of diabetes lead to diminished quality of life. As a means to avoid these complicationss, insulin therapy had evolved into a specialized regimen to achieve physiologic control of blood glucose, the so-called Multiple Daily Insulin (MDI) regimen which is a relatively new technique in the Philippines.
OBJECTIVE: To study the efficacy of Multiple Daily Insulin regimen in controlling plasma glucose and to evaluate patient's satisfaction with MDI regimen among Filipino type 2 diabetics who have been on MDI for at least 2 months.
RESEARCH DESIGN AND METHODS: Filipino patients (n=107) with uncontrolled diabetes were included in the study protocol. The majority were male, more than 60 years old and had been diabetic for more than 6 years. The mean body mass index was 27 kg/m2 and the mean baseline HbA1c was 9.2% + 2.65. This prospective cohort study was conducted between January 2006 to September 2008 at Cebu Doctors University Hospital Out-Patient Department. Efficacy was evaluated by HbA1c and treatment satisfaction was assessed with the Diabetes Treatment Satisfaction Questionnaire (DTSQ). Enrolled patients were followed up at week 12, 24 and 48.                                                                                                      
RESULTS: Mean HbA1c fell by 2.43 + 2.68 at week 12, 2.03 + 2.35 at week 24 and 1.73 + 2.23 at week 48 showing a statistically significant decrease of HbA1c among the 3 groups was not statistically significant (p = 0.52). The proportion of patients achieving an HbA1c of < 7% at week 12, 24, and 48 were 42%, 52% and 42%, respectively. Treatment satisfaction improved significantly (p = 0.000) with MDI regimen using the DTSQ at the end of the study.        
CONCLUSION: Multiple Daily Insulin Regimen is an effective treatment modality based on a significant lowering of HbA1c among the study population with uncontrolled type 2 diabetes mellitus. Patients were satisfied with the ragimen based on the positive treatment satisfaction. This, however, is contrary to popular belief that patients' quality of life is affected by insulin administration. Keywords: Multiple Daily Insulin Injection, Type Diabetes Mellitus, Treatment Satisfaction.

INTRODUCTIONThis study aims to determine the inpatient rehabilitation effectiveness (REs) and rehabilitation efficiency (REy) of hip fracture in a Singapore community hospital (CH), its association with socio-demographic variables, medical comorbidities and admission Shah-modified Barthel Index (BI) score as well as change in independent ambulation from discharge to 4 months later.

MATERIALS AND METHODSA retrospective cohort study using data manually extracted from medical records of all patients who had hip fracture within 90 days and admitted to a CH after the operation for rehabilitation. Multiple linear regressions are used to identify independent predictors of REs and REy.

RESULTSThe mean REs was 40.4% (95% Confidence Interval (CI), 36.7 to 44.0). The independent predictors of poorer REs on multivariate analysis were older age, Malay (vs non-Malay) patients, fewer numbers of rehabilitative therapy sessions and dementia. The mean REy was 0.41 units per day [CI, 0.36 to 0.46]. The independent predictors of poorer REy on multivariate analysis were higher admission BI and being non-hypertensive patient. The prevalence of independent ambulation improved from 78.9% at the discharge to 88.3% 4 months later.

CONCLUSIONCH inpatient rehabilitative therapy showed REs 40.4% and REy of 0.41 units per day and the optimum number of rehabilitative therapy session was from 28 to 41 in terms of rehabilitation effectiveness and the maximum rehabilitation efficiency was seen in those doing 14 to 27 sessions of rehabilitative therapy. The study also showed improvement in BI at discharge and improvement in the independent ambulation 4 months after discharge from the CH.

AIM: To study the effects of Sodium Hyaluronate (HA) and Bion Tears on corneal thickness in adult myopic patients.METHODS: A total of 38 cases (76 eyes) were involved in this study. Three consecutive corneal measurements (the thinnest point of the cornea,THN) were evaluated before and half an hour after the instillation of one drop of HA in one eye and Bion Tears in the other at random with the Orbscan Corneal Topography System II (Orbscan,Inc,Salt Lake City,UT,USA,Version 3.00E).RESULTS: There were no significant between-group differences in baseline variable (t=0.264). Thirty minutes after the instillation of HA and Bion tears,THN were significantly increased by 5.57±7.00μm (t=4.906,P<0.01) and 7.89±7.64μm (t=6.369,P<0.01) respectively. However,there were no between-group differences in THN changes(t=1.381,P>0.05).Increase in the corneal thickness were found in 32 eyes (84%) and 33 eyes (87%) for the HA and Bion tears group,respectively.CONCLUSION: Artificial tears including HA and Bion Tears can significantly increase the corneal thickness in a short period of time. Corneal thickness can be used as one of the objective indices for evaluating the quality and therapeutic role of artificial tears.
