Star CanVac-continuous curvilinear capsulorhexis - A novel, safe rhexis technique in intumescent total cataracts

Achieving a complete uniform capsulorhexis in an intumescent cataract is perhaps the most crucial and challenging step for surgeons. Star CanVac CCC is a new manual technique for creating a continuous curvilinear capsulorhexis (CCC) in intumescent total cataracts. Small centripetal tears in the shape of a star are created in the center of the anterior lens capsule by using a 26?G cystotome. This allows equal distribution of forces secondary to increased intralenticular pressure, thereby avoiding unidirectional or bidirectional tear extension. Subsequently, a 25?G flat?tipped fine cannula connected to a syringe is used to hold the free capsular flap. The piston of the syringe is withdrawn to create a stable suction pressure, and the rhexis is completed without withdrawing the instrument from the anterior chamber. Our technique is safe, affordable, and an alternative method to routine CCC or expensive techniques such as Femto or Zepto capsulotomy for white intumescent cataracts.

Thyroid disorders in patients with abnormal uterine bleeding in tertiary care hospital in Chengalpattu district

Background: A relationship between the thyroid gland and the gonads is suggested by far more frequent occurrence of thyroid disorders in women than in men by clinical appearance of goiter during pregnancy, puberty, and menopause. Aim of this study was to determine the association between menstrual irregularities and thyroid dysfunction. To analyse the pattern of menstrual dysfunction among women with a thyroid disorder.Methods: This cross-sectional study was done in Karpaga Vinayaga Institute of Medical Sciences and Research Center - obstetrics and gynecology OPD. Over 6 months in the year 2019. 100 women who presented with abnormal uterine bleeding with the below exclusion criteria. Detailed history taking with an emphasis on age, parity, infertility, and menstrual disorders. Evaluation by pelvic examination along with the general physical examination of those with menstrual complaints. Routine investigations like Hb, BT, CT, TLC, DLC, platelet count, and ABO-Rh in all. Then all patients were subjected to estimation of serum T3, T4, TSH with early morning samples.Results: Menorrhagia presents in 39.4% of patients in the normal cohort and 63.6% in the thyroid dysfunction cohort. Hypomenorrhea presents in 4% normal cohort and 9.1% thyroid dysfunction cohort. Hypothyroidism presents in 7.27%, subclinical hypothyroidism in 1.81%, and hyperthyroidism in 0.92% of patients. Amenorrhoea presents in 16.2% of patients of the normal cohort and 9.1% of patients of thyroid dysfunction cohort. No statistical significance between amenorrhoea and thyroid dysfunction.32.3% in the normal cohort and 36.4% in thyroid dysfunction cohort had a bulky uterus. No statistical association exists between thyroid dysfunction and uterine size. In a histopathological examination of the endometrium, 49.5% in the normal cohort and 54.5% thyroid dysfunction cohort reported as proliferative endometrium. Amenorrhoea; the significant association between abnormal uterine bleeding and thyroid disorder (10%).Conclusions: The significant association between abnormal uterine bleeding and thyroid disorder (10%). It brings into focus the increased incidence of hypothyroidism among women with menorrhagia.

Diversity of root associated microorganisms of selected medicinal plants and influence of rhizomicroorganisms on the antimicrobial property of Coriandrum sativum.

The total heterotrophic bacteria, actinomycetes and fungus were enumerated from the rhizosphere and non-rhizosphere soil of 50 selected locally available medicinal plants in and around Bharathiar University. In all the plants, population of microorganism were higher in the rhizosphere soil than in the non rhizosphere soil. Among the microorganisms, bacterial population was higher in number followed by fungus and actinomycetes. Of the medicinal plants, the maximum rhizosphere effect was observed in Annona squamosa and the minimum effect was seen in Eclipta alba and Cassia auriculata. Among the bacteria the dominant species was Bacillus followed by Pseudomonas, Enterobacter, Corynebacterium, Micrococcus and Serratia. The Streptomyces species was found to be dominant followed by Deuteromycetes and Frankia among the actinomycetes. Among the fungal isolates Rhizopus was found to be higher in number followed by Aspergillus, Penicillium, Mucor and Fusarium. About 70.96% of the bacterial isolates were found to be nitrate reducers and 90.60% of the bacteria solubilised phosphate. The rhizosphere bacterial isolates were also capable of hydrolyzing starch, cellulose, casein, urea and gelatin. The isolates of bacteria, actinomycetes and fungus were also able to produce phytohormone Indole-3-acetic acid (IAA). The maximum IAA production was recorded by Fusarium sp (5.8 mg/l). The rhizosphere bacterial isolates showed resistance to 14 commercially used antibiotics. In an attempt to check the influence of these plant growth promoting microorganisms on the antimicrobial property of Coriandrum sativum against Escherichia coli MTCC-443 and Aeromonas hydrophila MTCC-646, the results observed was not encouraging since the inoculants did not influence the antibacterial property. However extensive and in depth study is required to find out the influence of rhizomicroorganisms on the antibacterial property of medicinal plants. The other results clearly indicated that the rhizosphere microorganisms could be exploited for its innumerable properties and active metabolites.
