Outcomes of 8 × 8 mm osteotomy in powered external dacryocystorhinostomy

Purpose: To study the endoscopic ostium characteristics and outcome of 8 × 8 mm osteotomy in external dacryocystorhinostomy (DCR) using the microdrill system. Methods: This prospective interventional pilot study was performed on 40 eyes of 40 patients with primary acquired nasolacrimal duct obstruction (NLDO) from June 2021 to September 2021 in patients undergoing external DCR. An 8 × 8 mm osteotomy was performed using round, cutting burr attached to a microdrill system. Success was defined as patent ostium on lacrimal syringing (anatomical) and a Munk score <3 (functional) at 12 months. Postoperative endoscopic ostium evaluation was done using a modified DCR ostium (DOS) scoring system at 12 months. Results: The mean age of the study participants was 42.41 ± 11.77 years and the male?to?female ratio was 1:4. The mean duration of surgery was 34.15 ± 1.66 minutes and that for osteotomy creation was 2.5 ± 0.69 minutes. The mean intraoperative blood loss was 83.37 ± 11.89 ml. Anatomical and functional success rates were 95% and 85%, respectively. The mean modified DOS score was “excellent” in 34 patients (85%), “good” in 1 patient (2.5%), “fair” in 4 patients (10%), and “poor” in 1 patient (2.5%). Complications included nasal mucosal injury in 10% (4/40) of patients, complete cicatricial closure of ostium in 2.5% (1/40), incomplete cicatricial closure in 10% (4/40), nasal synechiae in 5% (2/40), and canalicular stenosis in 2.5% (1/40). Conclusion: An 8 × 8 mm–sized osteotomy created by powered drill and covered by lacrimal sac–nasal mucosal flap anastomosis in external DCR is an effective technique that has minimal complications and shorter surgical time

Correction of pre-existing astigmatism by on-axis incision size modulation in manual small-incision cataract surgery

Purpose: To study the effect of wound size modulation on pre?existing astigmatism by on?axis placement of incision in manual small?incision cataract surgery (MSICS). Methods: In this prospective interventional study conducted at a tertiary care centre, 40 eyes of 40 consecutive senile cataract patients with 1.00�00 D corneal astigmatism were enrolled for the study. MSICS by modified Blumenthal抯 technique was performed through 6.0, 6.5, and 7.0 mm on?axis incision in 1.0�49 D (group A), 1.50�99 D (group B), and 2.00�00 D (group C) astigmatism, respectively. Surgically induced astigmatism (SIA) was calculated by vector analysis and double angle plots (DAP) at 12 weeks postoperatively. Results: There were 22 males and 18 females with mean age of 58.12 � 1.18 years. The mean SIA at 12 weeks was 0.85 � 0.28 D in group A (17 eyes), 1.32 � 0.65 D in group B (10 eyes), and 1.91 � 0.69 D in group C (13 eyes). The overall median uncorrected visual acuity was 0.18 (IQR = 0 to 0.2). The mean astigmatism decreased from 1.95 � 0.74 D to 1.04 + 0.57 D (P = 0.00) in superior incision and from 1.70 + 0.50 D to 0.92 � 0.45 D (P = 0.00) in temporal incision group with central shift of centroid in all cases. Conclusion: The customization of on?axis external incision size can be used to manage pre?existing corneal astigmatism of less than 3.00 D using both temporal and superior incisions effectively

Myelomatous pleural effusion as an initial presenting sign in a case of multiple myeloma

Multiple Myeloma (MM) is a neoplastic disease which mainly affects bone marrow but rarely may infiltrate extramedullary tissues as well. Myelomatous pleural effusions (MPE) develop due to extension of plasmacytoid cell lesions of thoracic bones into pleural tissue and directly presenting as an initial sign in a case of MM is exceedingly rare. It indicates poor prognosis, resistance to treatment and more chance of relapse in spite of aggressive chemo-radiotherapy. The effusions of serous cavities in MM generally develop as a late complication of the disease like heart failure, renal failure, pneumonia and amyloidosis. We are reporting a rare case of IgG subtype myelomatous pleural effusion demonstrating abundance of plasmacytoid cells in pleural fluid. Bone marrow smear examination favoured the diagnosis of multiple myeloma with the presence of predominant population of plasma cells with high cellularity. There were also presence of a heterogenous myelomatous mass lesion in the right infratemporal fossae, multiple erosive lesions in ribs, vertebral bodies, skull and pelvic bones. Pleural fluid and serum protein electrophoresis demonstrated the presence of gamma monoclonal protein peaks confirming the diagnosis.

Microfilarae in malignant mesothelioma associated pleural effusion with blood microfilaremia: a rare association

Filariasis has a wide spectrum of presentation and usually involves the lung in the form of tropical pulmonary eosinophilia with pulmonary infiltrates and peripheral eosinophilia. Filariasis presenting with pleural effusion is an unusual presentation. Malignancy in association with filarial pleural effusion is extremely rare. In this context, we hereby report a case of 45 year old male who presented with right sided chest pain, cough, fever and generalized weakness. Pleural fluid cytology revealed microfilaria and pleural biopsies from pleural nodules confirmed malignant mesothelioma. Peripheral blood smears taken at night exhibited microfilaria with normal eosinophil counts, which is further uncommon. Role of filariasis in tumorigenesis is controversial.

Intention toward optimal breastfeeding among expecting mothers in Angul district of Odisha, India.

This paper aims to assess the prenatal breastfeeding intention and its predictors in Odisha, a state in India. Data were collected from 218 rural pregnant women of Angul district of Odisha, India in 2012. About 33% of the women lacked the intention to exclusively breastfeed their babies for 6 months. Prelacteal feeding was intended by one-third of the women while 61.5% of the women intended to feed water during the first 6 months of birth. Women of an older age [odds ratio (OR) = 1.30; 95% confidence interval (CI) = 1.09-1.55], with more education (OR = 1.14; 95% CI = 1.08-1.32), belonging to lower castes [other backward caste (OBC)-OR = 21.33; 95% CI = 4.29-106.0, scheduled caste (SC)-OR = 22.77; 95% CI = 2.47-199.1, scheduled tribe (ST)-OR = 26.16; 95% CI = 4.10-174.8), and lesser number of living sons (OR = 0.59; 95% CI = 0.22-0.94) were more likely to have a higher intention for optimal breastfeeding than those of a lower age, with less education, belonging to a higher caste, and with more number of living sons. Awareness generation programs need to be strengthened to educate pregnant women with appropriate and recommended breastfeeding guidelines to establish optimal breastfeeding practices.

Drug-induced nephrotoxicity.

Drug-induced nephrotoxicity is an extremely common condition and is responsible for a variety of pathological effects on the kidneys. Drug-induced acute renal failure (ARF) accounted for 20% of all ARF cases. Drugs showed to cause nephrotoxicity exert their toxic effects by one or more common pathogenic mechanisms. Although it is impossible to present all the drugs causing the nephrotoxicity, this article will summarize the mechanism of injury associated with particular common medications, discuss clinical presentations, renal markers, and evaluate strategies that prevent or minimize renal injury. Drug-induced nephrotoxicity tends to be more common among certain patients and in specific clinical situations. Therefore, successful prevention requires knowledge of pathogenic mechanisms of renal injury, patient-related risk factors, drug-related risk factors, and preemptive measures, coupled with vigilance and early intervention. General preventive measures include using alternative nonnephrotoxic drugs whenever possible; correcting risk factors, if possible; assessing baseline renal function before initiation of therapy, followed by adjusting the dosage; monitoring renal function and vital signs during therapy, and avoiding nephrotoxic drug combinations. Surprisingly, little information is available to guide us with respect to avoiding complications in critical illness; therefore, it is necessary to follow the guidelines.

Medicinal Plants as Agent of Anticonvulsant Activity.

Epilepsy is one of the major neurological disorders where modern drug therapy is complicated by side-effects, teratogenic effects and long-term toxicity. Medicinal plants have been an important source for the discovery of novel bioactive compounds which served and continue to serve as lead molecules for the development of new drugs. Large body of evidence has accumulated to demonstrate promising potential of medicinal plants used in various traditional, complementary and alternative systems. Several Indian medicinal plants have been studied for pharmacological activity in recent years. To understand the mechanism of action, the researchers have worked at molecular levels and several significant phytochemicals have been isolated. The present review is aimed at compiling data on promising Indian medicinal plants, which are being used as anticonvulsant agents, are discussed.

Role of corticosteroids in the treatment of tuberculosis: An evidence-based update.

Corticosteroids are often used as an adjunct in the treatment of various forms of tuberculosis (TB) and for the prevention of complications, such as constrictive pericarditis, hydrocephalus, focal neurological deficits, pleural adhesions, and intestinal strictures. Notwithstanding, they have been proven in clinical trials to improve the following outcomes only — death or disability in human immunodeficiency virus (HIV)-seronegative patients with tubercular meningitis and tubercular pericarditis. Despite a lack of specific evidence for efficacy in HIV co-infected patients with tubercular meningitis or pericarditis, corticosteroids are generally recommended in them as well. Corticosteroids significantly decrease the risk of pleural thickening in patients with tubercular pleural effusion; the clinical significance of this finding, however, is unclear. Recently, it has been demonstrated that use of corticosteroids improve the morbidity in HIV co-infected patients with paradoxical TB immune reconstitution inflammatory syndrome (IRIS). However, evidence favouring the use of corticosteroids in other clinical situations is sparse or lacking. Likewise, the biological mechanisms underlying their beneficial effect in TB meningitis and pericarditis remain poorly understood.
