RESUMO

BACKGROUND: Tuberculosis (TB) is an airborne disease caused by Mycobacterium tuberculosis (M. tuberculosis). The world is currently facing challenges due to the spread of anti-tuberculosis drug-resistant of M. tuberculosis. Isoniazid-resistant (INH), is one of the first-line anti-tuberculosis agents that has a high resistance case. This study used Multiplex allele-specific Polymerase Chain Reaction (MAS-PCR) to detect the most common mutations associated with isoniazid resistance on inhA, katG, and ahpC gene. METHODS: This study used samples from clinical isolates of M. tuberculosis which had been tested for their antibiotic sensitivity of first-line anti-tuberculosis drugs. The DNA extraction process was carried out using the boiling method and then amplified with specific primers for inhA, katG, and ahpC genes using the MAS-PCR method. The results are then read on the electrophoretic gel with an interpretation of the mutation gene when the target gene DNA bands were absent according to the allele-specific fragments target. RESULTS: A total of 200 isolates were tested in this study consisting of isoniazid-resistant and susceptible with the largest distribution of Multi-Drug Resistant (MDR) isolates with a total of 146 isolates (73%). The most significant gene mutation was on the ahpC gene in 61 isolates (30,5%) and the combination mutation of the katG + ahpC gene in 52 isolates (26%) with sensitivity and specificity of the test reaching 87% and 42% for the detection of INH-resistant. CONCLUSION: Mutation on the ahpC gene has the highest percentage in this study. AhpC gene can be considered one of the essential genes to be tested for the cause of isoniazid-resistant. Using MAS-PCR for detecting gene mutation in isoniazid-resistant was simple and easy, it has the potential to be widely used as a rapid screening molecular test.

RESUMO

This review aimed to evaluate the effect of bevacizumab on adverse events and the quality of life (QoL) from colorectal cancer (CRC) patient. Methods: A literature search was conducted from PUBMED, MEDLINE databases and some valid literatures from another databases that published in the last 10 years, and the design is an observational and randomized controlled trial (RCT). Results: CRC is a malignancy, which happens in the colon or rectum. One of the therapy for CRC is by using bevacizumab, a monoclonal antibody. However, the usage of bevacizumab is still become a controversy because of its clinical complications. Several studies showed that bevacizumab could cause some adverse events in the cardiovascular, gastrointestinal, hematology, and others body systems and affect the CRC patient QoL. However, the clinical complication of this drug is also affected by the combination therapy regimen used. Conclusions: The use of bevacizumab could cause some adverse event in different aspects, including cardiovascular, gastrointestinal, hematology, and others. Some of those are significant, but others are not. Besides that, using bevacizumab as a treatment regiment could also affect the QoL of CRC patients, but it is also affected by the combination therapy regimen used.

RESUMO

Rhegmatogenous retinal detachment (RRD) is a serious and emergency condition that may cause visual disturbance. Treatment includes pars plana vitrectomy with a tamponade such as intraocular gas or silicone oil (SO). In many countries, silicone oil is still favorable compared to intraocular gases as tamponade for reattachment of retinal detachment surgery. The application provides a higher anatomical success rate, especially in cases of proliferative vitreoretinopathy (PVR) that were previously considered untreatable. Objective assessment of the retinal nerve fiber layer (RNFL) using optical coherence tomography (OCT) in the eye with silicone oil tamponade is a challenge because of the limitations and difficulties in taking images. This study aims to assess the RNFL thickness changes in rhegmatogenous retinal detachment patients using SO tamponade and its subsequent removal conducted on a total of 35 post-operative RRD patients. Central macular and RNFL thickness, as well as best-corrected visual acuity (BCVA), were recorded at the time of tamponade and after the removal of the SO at 1, 4, and 8 weeks, respectively. The results showed that the changes in RNFL thickness significantly decreased in the group of ≤6 months, especially in the superior and temporal quadrants, and BCVA increased after SO removal (p < 0.05). Central macular thickness was significant (p < 0.001) at the end of the visit. Improved visual acuity is associated with decreased RNFL and central macular thickness after SO removal.

RESUMO

Thelaziasis is a parasitic disease caused by a nematode of genus Thelazia, which is rare in the world, including Indonesia. The definitive hosts for Thelazia are canids, felids, mustelids, and other mammals, while the vector is drosophila flies. Consequently, this study reported an uncommon occurrence of human ocular thelaziasis in Indonesia. Based on the patient's complaints and physical examination, we found a living worm that move actively in the anterior chamber; then documentation is carried out both during the examination at the polyclinic and in the operating room. The surgery was performed using topical anaesthesia, clear corneal incision, and removing worm through the main port. Morphological examination from the parasitology laboratory showed that the worm was Thelazia callipaeda species. Following this intervention, the patient was given an oral anti-helminthics drug, topical and oral antibiotics, topical steroid, and surgical treatment. There was no recurrence or appearance of any other symptoms reported in 2 months of follow-up.

RESUMO

BACKGROUND: Diabetic retinopathy (DR) is the most common microvascular complication of diabetes. Retinol and α-tocopherol of diabetic models prevent the damage of photoreceptor and retinal ganglion cells (RGC) caused by hyperglycemia. OBJECTIVE: This study aims to examine the effect of retinol and α-tocopherol on photoreceptor and RGC densities and the expression of caspase-3 and -7 on the retinal layers of the diabetic rat model. METHODS: Alloxan 150 mg/kg body weight single dose was used to develop animal models, which were separated into eight groups. These consist of one group without intervention (group 1), one positive control with only induced alloxan (group 2), and others receiving retinol (group 3 and 6), α-tocopherol (group 4 and 7), or their combination (group 5 and 8). Furthermore, histopathological examination was performed using Hematoxylin-Eosin staining to evaluate the photoreceptor and RGC densities, while immunohistochemistry staining evaluated the caspase-3 and -7 expressions. RESULTS: In the treatment group, the highest and lowest densities were identified in diabetic rats given α-tocopherol (group 7) and retinol (group 3) respectively. The caspase-3 and -7 expression showed that the group given α-tocopherol (group 7) had the lowest value. CONCLUSION: In diabetic rats, retinol and α-tocopherol compounds maintained densities and prevented photoreceptor and RGC death. However, α-tocopherol was more promising than retinol or combinations in the prevention of retinal cells apoptosis.

RESUMO

Background: Myopia is a condition in which the visual images come to a focus in front of the retina of the eye. This disease is a major cause of visual disability, which presents in 108 million persons globally. Purpose: This study aims to determine the relationship between the degree of myopia, the axial length, and the choroidal thickness (CT). Methods: This is an observational analytical study that made use of a cross-sectional design. A total of 59 participants with refractive errors underwent treatment at Hasanuddin University Hospital and 116 eyes were measured and analyzed. The choroidal thickness was measured using the Enhance Depth Imaging OCT (EDI-OCT) tool, which is divided into nine observational areas. Furthermore, all data obtained were compared using statistical analysis, such as the one-way ANOVA and Pearson correlation test (p < 0.05). Results: There was a significant relationship between the choroidal thickness with axial length (p < 0.05) and myopia degrees (p < 0.05). Conclusions: The thickness of the choroid decreases with an increase in the axial length and degree of myopia, which further indicates that the higher the myopia degree, the thinner the choroidal vasculature.

RESUMO

INTRODUCTION: This study aimed to assess vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) levels within vitreous and blood serum samples of patients with rhegmatogenous retinal detachment (RRD) and their relationship to the development of proliferative vitreoretinopathy (PVR). METHODS: Seventeen eyes of patients with RRD were included in the RRD group and divided into three subgroups: RRD without PVR, RRD with PVR grades A and B, and RRD with PVR grade C. Five control eyes (nucleus and intraocular lens drop) were included in this study. Blood serum and vitreous samples were collected during vitrectomy. VEGF-A and PDGF-AA levels were determined by enzyme-linked immunosorbent assay. RESULTS: The mean vitreous VEGF-A level in the RRD group was 131.71 ± 58.25 pg/mL, and the mean vitreous PDGF-AA level was 174.62 ± 65.17 pg/mL. Both levels were significantly higher in the RRD group compared with the control group (p < 0.05). Vitreous VEGF-A and PDGF-AA levels were the highest in RRD with PVR grade C subgroup, with mean levels of 179.87 ± 21.02 pg/mL and 229.44 ± 14.09 pg/mL, respectively (p < 0.05). The vitreous VEGF-A/PDGF-AA ratios in the RRD subgroups were completely different. CONCLUSION: Based on the tendency of VEGF-A and PDGF-AA levels, RRD surgery has to be performed as soon as possible prior to retinal cell death and membrane proliferative formation.

RESUMO

This article presents a case of posterior lensectomy through 3-port pars plana vitrectomy for the management of phacomorphic angle closure. A 67-year-old man presented to the outpatient department with headache and decreased vision in his left eye for the past 3 days. Visual acuity 2/60, intraocular pressure (IOP) >60 mm Hg, and the anterior chamber (AC) depth Van Herick grade 1. A complete ophthalmologic examination revealed a phacomorphic angle closure. Serial management was performed consisting of mannitol 20% intravenously, laser peripheral iridotomy, and trabeculectomy. However, the depth of the AC became more shallow, and the IOP remained high. Lens extraction as definitive therapy could not be performed because of the adhesion of the iris and anterior lens capsule to the corneal endothelium; thus, posterior lensectomy using 3-port pars plana vitrectomy, and phacofragmatome was performed. Once the corneal thickness was returned to normal, and the AC depth was sufficient, the patient underwent secondary intraocular lens implantation. A significant improvement in visual acuity, normal IOP, and AC depth were achieved after the management of the posterior approach. Thus, this posterior approach should be considered a good option of management technique in cases with phacomorphic angle closure with very shallow AC depth and a fragile cornea.
