ABSTRACT
The high prevalence of mature, hypermature, and traumatic cataracts in developing countries, combined with the limited availability of surgical resources and skill by anterior segment surgeons to manage the resultant aphakia, leaves the patient needlessly blind. Relying on posterior segment surgeons, expensive surgical setup, and appropriate lenses for aphakia management limits the number of patients receiving a secondary intraocular lens (IOL). Utilizing the well-acknowledged flanging technique and the readily available polymethyl methacrylate (PMMA) lenses with dialing holes in their optic, a hammock can be created through the dialing holes using a 7-0 polypropylene suture on a straight needle. This 4-flanged scleral fixation through the dialing hole of an IOL makes scleral fixation of PMMA lens possible by even anterior segment surgeons without requiring any specialized equipment or scleral fixated lens with eyelet. This technique was successfully performed in a series of 103 cases with no incidence of IOL decentration.
ABSTRACT
Small traumatic iridodialysis (ID) may be asymptomatic, but large ones usually cause polycoria and corectopia, leading to symptoms like diplopia, glare, and photophobia. The management of ID, including medical and surgical methods, depends upon the patient’s symptoms. Mild glare and diplopia can be treated either with atropine, antiglaucoma medications, tinted spectacles, colored contact lens, or corneal tattooing, but extensive IDs require surgical options. The surgical techniques are challenging due to the iris texture and the damage encountered during the primary surgery, the narrow anatomical workspace for repair, and the associated surgical complications. Numerous techniques have been described by several authors in the literature; each has its advantages and disadvantages. All the procedures described previously involve conjunctival peritomy, scleral incisions, and suture knots and are time consuming. Here, we report a novel transconjunctival, intrascleral, knotless, and ab-externo, double-flanged technique for repair of large ID with a 1-year follow-up
ABSTRACT
Purpose: To evaluate the visual and surgical outcomes of cataract surgery in patients with posterior polar cataract (PPC) and to evaluate the benefits of preoperative anterior segment optical coherence tomography (AS?OCT). Methods: This was a retrospective, single?center study. Case records of patients diagnosed with PPC who underwent cataract surgery either by phacoemulsification or manual small?incision cataract surgery (MSICS) from January to December 2019 were analyzed. Data collected include demographic details, preoperative best corrected visual acuity (BCVA), AS?OCT, type of cataract surgery, intraoperative and postoperative complications, and visual outcome at 1?month follow?up. Results: One hundred patients were included in the study. Preoperative posterior capsular defect was noted on AS?OCT in 14 patients (14%). Seventy?eight underwent phacoemulsification and 22 underwent MSICS. Intraoperatively, posterior capsular rupture (PCR) was seen in 13 patients (13%) and cortex drop was noted in one among them (1%). Out of 13 PCRs, 12 were found to have posterior capsular dehiscence preoperatively in AS?OCT. The sensitivity of AS?OCT for detecting posterior capsule dehiscence was 92.3% and specificity was 97.7%. The positive predictive value and negative predictive value were 85.7% and 98.8%, respectively. There was no significant difference in the incidence of PCR between phacoemulsification and MSICS (P = 0.475). The mean BCVA at 1 month was found to be better with phacoemulsification than MSICS (P = 0.004). Conclusion: Preoperative AS?OCT has excellent specificity and negative predictive value in identifying posterior capsular dehiscence. It thus helps to plan the surgery and counsel patients appropriately. Both phacoemulsification and MSICS provide good visual outcome with similar complication rates.
ABSTRACT
Single haptic iris fixation technique is used where there is a loss of 6 clock hours anterior capsular support. It helps the anterior segment surgeon to fix the intraocular lens to the iris on the side of absent capsular support and place the other haptic over the capsular support. A 10-0 polypropylene suture on a long-curved needle is only used to take a suture bite on the side of capsule loss. Meticulous automated anterior vitrectomy is done. Then, the suture loop below the iris is taken out and the loops are twirled multiple times around the haptic. The leading haptic is then gently glided behind the iris, and the trailing haptic is gently placed on the other side using forceps. The suture ends are trimmed and internalized into the anterior chamber and then externalized through the paracentesis using a Kuglen hook, and the knot is tied and secured
ABSTRACT
Background: Acute febrile illness is very common among patients seeking hospital care in tropical country like India. This study was conducted to evaluate etiology and clinical profile of Acute Undifferentiated Febrile Illness (AUFI) in a tertiary care hospital.Methods: This study was conducted in 175 patients with acute febrile illness who were admitted in the medical wards and ICU from January 2018 to June 2019 in a tertiary care hospital. Clinical examination and investigations like complete hemogram, liver function test, renal function test, smear for malarial parasite, widal test, urine analysis blood and urine culture, antibody titters for dengue, Leptospirosis and imaging were done.Results: Out of 175, 94 (54%) were males and 81 (46%) were females. The commonest etiology was dengue (19%) followed by enteric fever (18%), scrub typhus (16%), malaria (14%), tuberculosis (6%) and leptospirosis (5%). 138 (79%) patients had less than 14 days of fever of which dengue was the most common and 37 (21%) patients had more than 14 days of fever with tuberculosis being predominate. Other common symptoms were chills/rigors, headache and myalgia seen in 77%, 71% and 42% respectively. Icterus was seen in malaria (42%) and leptospirosis (38%). Elevated transaminases levels were observed with dengue, leptospirosis, scrub typhus, enteric fever and malaria. ARDS was most common in scrub typhus.Conclusions: Among acute febrile illness, dengue and enteric fever were the most common in this study. A thorough and probing search for an eschar is very important in scrub typhus. The treating physician has to keep in mind the comprehensive list of differential diagnosis for patients with febrile illness and anticipating the complications.
ABSTRACT
Abstract Objective: To assess the antibacterial and smear layer removal ability of Trigonella foenum, Syzygium cumini, Terminalia chebula seed extracts against E. faecalis dentinal biofilm. Material and Methods: Agar well diffusion, micro broth dilution assay and time-kill curve assay were performed to determine the antibacterial activity. The ability of the herbal extracts to remove the smear layer on the root canal surface was assessed by scanning electron microscopy. Results: Antibacterial activity was observed for the extracts of S. cumini and T. chebula on E. faecalis dentinal biofilm and its planktonic counterparts. The smear layer was efficiently removed by the seed extracts of T. chebula alone. Seed extracts of T. foenum neither possessed antibacterial effect nor smear layer removal ability. Conclusion: The extracts of T. chebula seeds may replace conventional irrigant due to its antibacterial properties and smear layer removing the ability. The extracts of S. cumini may be used as an intracanal medicament as it exhibited a bactericidal effect against the E. faecalis dentinal biofilm following 18 hours of incubation.

Background: Postmastectomy radiation (PMRT) to the chest wall using electron beam treatment with uniform bolus was practiced at our institution. The planning target volume (PTV) included the chest wall and the internal mammary nodes (IMN) along with supraclavicular nodal regions. The varying thickness of the postmastectomy chest wall and the varying position of the IMN resulted in dose inhomogeneity in the PTV. In addition, there was the risk of increased lung and cardiac doses. In this prospective study, we report the making of a custom-made bolus using dental wax called “step bolus.” Materials and Methods: From March 2010 to January 2011, 167 patients received PMRT. As conformal photon plans were not acceptable in 48 patients, they were treated with single energy electrons and custom-made bolus. Results: Addition of the step bolus improved dose distribution to the PTV reduced the mean lung dose %, the mean heart dose % and lung dose (D10, D20, D30, D50, and D70). Forty-seven patients had Grade 2, and one patient had Grade 3 skin toxicity. Acute symptomatic radiation pneumonitis was observed in one patient. At 5 years, 29 patients were alive with a median follow-up of 32 months and no local recurrences were observed. One patient died of myocardial infarction unrelated to treatment, one patient did not come for follow-up, 22 patients had systemic metastases, and 24 patients were disease free. Conclusion: A custom-made step bolus using dental wax can be used for tissue compensation in electron beam therapy with resulting good local disease control and acceptable toxicity.
ABSTRACT
Background: Various studies have been done to assess the use of serum amylase, serum lipase, and amylase/lipase (A/L) ratio to differentiate between the causes of pancreatitis. Scoring systems (Ranson’s, Glasgow, and APACHE II) have been developed to assess the severity of pancreatitis. Computed tomography (CT), a gold standard for prognosticating pancreatitis, is expensive and affordability is a concern in developing country like ours. Methodology: We did a retrospective study in a tertiary care hospital to assess the use of A/L ratio to predict the severity of acute pancreatitis and to correlate with the presence on necrosis in comparison to that given by CT. Results: The median A/L ratio was higher among those with severe and necrotizing pancreatitis, 0.19 (interquartile range [IQR] 0.124–0.304) and 0.183 (IQR 0.117–0.300), respectively. Cutoff of 0.14 was taken, based on the receiver operating characteristic curves, which could predict severity with 75% sensitivity and 53% specificity and necrosis with 73% sensitivity and 55% specificity. Higher A/L ratio correlated with a decrease in hematocrit (P = 0.08), blood glucose (P = 0.042), and aminotransferase (P = 0.03), which are indicators of clinical severity. Increase in A/L ratio had an increased trend to a longer duration of stay and a higher chance of detecting multiorgan dysfunction syndrome. Conclusions: A/L ratio of >0.14 can be used as a predictor of severity as it indicates the presence or absence of necrosis, which further aids in referral and the need for a CT scan in low-resource settings
ABSTRACT
Introduction: Being a houseman in Malaysian hospitals can be very stressful. Stress can affect decision making to a great extent while addressing the needs of the patient in an emergency setting. This necessitated a study to find out the main sources of stress among housemen. Methods: This was a cross-sectional descriptive study carried out among 55 housemen using a questionnaire on sources of stress. The data was analysed using SPSS version 17. Results: A total of 16 factors leading to stress were studied among the housemen. Poor work and social life balance, annoying non-clinical personnel and medico-legal threats were among the top causes of stress. Conclusion: The factors leading to stress among housemen should be considered for effective working of the hospital and improving the workplace atmosphere for the housemen.

Cell culture models for hepatitis B virus (HBV) remain the mainstay for screening and testing the efficacy of anti‑hepatitis B virus agents. Gradient‑based ultracentrifugation followed by Southern Blotting is used for hepatitis B virion estimation in cell culture; this method has several limitations. We report the development of an assay using a commercially available HBsAg‑ELISA plate for immunocapture followed by real‑time PCR for quantification of hepatitis B virions in cell cultures. This assay is rapid, highly sensitive (50 copies/reaction) and highly specific for virion‑associated DNA. In addition, the assay requires only 20 μL of supernatant, allowing scaling down of transfections.
ABSTRACT
Aims: To develop, validate and quantify the content of flavonoids luteolin and apigenin in aerial parts of methanol leaf extract of Bacopa monnieri (B. monnieri) by reverse phase liquid chromatography. Study Design: High Performance Liquid Chromatography Place and Duration of Study: Department of Pharmaceutical Analysis, KMCH College of Pharmacy, Coimbatore and Indian Pharmacopoeia Commission, Ghaziabad, India from 1.7.2010 to 30.6.2011. Methodology: Separation and quantification of flavonoids was performed on a C18 column (5μm, 200mm×4.6mm, id.) using potassium dihydrogen phosphate buffer (20mM, pH 3.5 adjusted with ortho phosphoric acid, v/v) and acetonitrile as mobile phase with a flow rate of 1ml/min. The column effluents were monitored at 348nm with column temperature kept at 30±1ºC. Results: A validated method for simultaneous estimation of luteolin and apigenin was developed, where limits of detection and quantification was found to be 0.03 and 0.91μg/ml for luteolin, 0.041 and 0.13μg/ml for apigenin respectively. The percentage of these phytoconstituents recovered was in the range of 98.07-99.71 (%RSD<2%). Conclusion: The developed validated HPLC method was found to be accurate, precise and robust and may be used for analysis of luteolin and apigenin in the extracts of B. monnieri.
ABSTRACT
We investigated the anti-nociceptive effect of Excoecaria agallocha (E.agallocha) against chemically and thermally induced nociception, Albino mice received a dose of 10, 15, 20, or 25 mg/kg of alkaline chloroform fraction (Alk-CF) of E.agallocha by oral administration. Compared with controls, Alk-CF decreased the writhing numbers (P<0.01) in a dose dependent manner. Further we determined that, Alk-CF contained, a potent compared to control, also potent anti-nociceptive agent that acted via opioid receptors and using HPLC, identified this compound as Rutin. Docking simulation demonstrated that Rutin interacted strongly with cyclooxygenase, forming a number of specific hydrogen bonds. In conclusion we have identified peripheral and central anti-nociceptive activities of E.agallocha that involve opioid receptor, and in which the active compound is Rutin.

Background. We prospectively studied the prevalence, type and causes of anaemia in newly diagnosed patients with lymphoid malignancies. Methods. Between January 2007 and June 2008, a total of 316 newly diagnosed, consecutive patients (aged 15 years or above) of Hodgkin lymphoma, non-Hodgkin lymphoma and chronic lymphocytic leukaemia with anaemia (haemoglobin <11 g/dl), were analysed to determine the prevalence and a subgroup of 46 patients was analysed for the cause of anaemia. Results. Hodgkin lymphoma, non-Hodgkin lymphoma and chronic lymphocytic leukaemia were the diagnoses in 81 (25.8%), 203 (64.7%) and 30 (9.6%) patients, respectively. Anaemia was present in 134 patients (42.4%). Anaemia of chronic disease was present in 33/46 (71.7%) and iron deficiency in 18/46 (39.1%) patients. Vitamin B12 and/or folate deficiency was detected in 10/46 (21.7%) patients (B12 deficiency alone in 7, folate deficiency alone in 1 and combined B12 and folate deficiency in 2). Autoimmune haemolytic anaemia was detected in 5/46 (10.9%) although direct Coombs test was positive in 17/46 (37%) patients. Among patients with Hodgkin lymphoma and non-Hodgkin lymphoma, anaemia due to bone marrow involvement was present in 16/40 (40%). In most patients with bone marrow involvement, anaemia was due to other causes. In only 3 patients, anaemia was attributable to bone marrow involvement alone. Anaemia was multifactorial in 18/46 (39.1%) patients. Nutritional deficiency alone or in combination was present in 22/46 (47.8%) patients. Conclusion. Anaemia is common in lymphoid malignancies at initial presentation. Besides managing anaemia of chronic disease and bone marrow involvement, nutritional and autoimmune causes should be ruled out.
