Sutureless and glue-free limbal-conjunctival autograft in primary and recurrent pterygium: A pilot study

Purpose: To evaluate and analyze the outcomes of sutureless and glue?free limbal?conjunctival autografting in cases of primary as well as recurrent pterygium. Methods: This prospective interventional study was carried out between February 2019 and February 2020 at a tertiary care hospital in North India. A total of 70 patients with pterygium underwent sutureless and glue?free limbal?conjunctival autograft. The patients were divided into two groups: group 1 patients with primary pterygium (n = 45), group 2 patients with recurrent pterygium (n = 25). The patients were followed up till 12 months postoperatively. Results: The mean age of the patients in group 1 and group 2 was 37.04 ± 8.69 years and 32.52 ± 6.49 years, respectively (P = 0.04). Postoperatively, no recurrence was recorded in group 1. Recurrence was noticed in two patients (8%) of group 2. The BCVA changed from 78.73 ± 9.86 letters to 80.15 ± 7.29 letters (P = 0.45) and from 79.6 ± 6.44 letters to 79.8 ± 5.86 letters (P = 0.45) in group 1 and group 2, respectively. Graft edema was found in seven (15.55%) cases of group 1 and four (16%) cases of group 2. Graft retraction was found in two (4.44%) cases of group 1 and three (12%) cases of group 2. Conclusion: Sutureless and a glue?free limbal?conjunctival autograft is a safe and effective treatment option for primary as well as recurrent pterygium.

Effect of Body Condition Score (BCS) on Production Performance of Sahiwal Cattle

The present investigation was carried out with the total of 18 Sahiwal cattle of 1st to 4th parity were selected for the study and distributed into three different groups based on their pre calving BCS (before 15 days of expected date of calving) namely G1 (2.50 - 3.00), G2 (3.25 - 3.75) and G3 (4.00 and above) with six animals in each group. The average fortnight milk yield increased up to 60th day and thereafter declined up to 90th day in G1, G2 and G3 group of animals, which was significant (p<0.05) up to 75th day. G3 group animals had highest average fortnightly cumulative Milk yield (Kg) in entire study period. Highest 305 days predicted lactation milk yield (2462.66 Kg /lactation) and average peak yield (16.50 Kg/ animal) was obtained in G3 group animals and the lowest predicted lactation milk yield (1870.68 Kg/lactation). The 305 days predicted lactation milk yield in G2 group animals was 2356.75 Kg /lactation and average peak yield was 14.90 Kg/ animal. The G3 group animals also attained their peak yield in 46 days compared to G2 and G1 group animals with 51 and 54 days, respectively. The persistency of milk production was highest in G2 group animals with 65.63 % followed by G3 and G1 group animals. The studied revealed that BCS had a significant (P<0.05) effect on post-partum estrus and service period in experimental animals

Evaluation of efficacy and safety of intralesional bleomycin in the treatment of common warts: Results of a pilot study

Background: This study evaluated the efficacy and safety of intralesional bleomycin in the treatment of common warts in 50 (32 men, 18 women) patients aged between 14 and 80 (mean ± SD, 28.5 ± 13.27) years. Methods: The warts were present over dorsal hands, feet, palms, soles and periungual skin for 1 month to 10 years. They were infiltrated with bleomycin (1 mg/ml) till blanching. The total cumulative dose did not exceed 2 mg in one session. The treatment was repeated after paring of eschar at 2 weeks in case there was no or partial response. The patients were reviewed at 4, 12 and 24 weeks for cure, adverse effects or recurrences and outcome satisfaction levels. Results: Complete cure without recurrence occurred in 40 (80%) patients and partial response occurred in 7 (14%) patients at the end of the 24-week study period. Three patients did not complete follow-up. No major systemic or local adverse effects other than injection site pain for 2–3 days were noted. All cured patients were very satisfied (Likert scale 5). Conclusion: Intralesional bleomycin appears to be an effective and safe treatment for common warts including palmoplantar and periungual warts. It carries the advantage of low dose, no significant adverse effects and high patient satisfaction. Small number of patients, lack of a control group, comparing different bleomycin concentrations and a short follow-up are a few limitations of this study. Better designed studies are warranted for this useful treatment modality.

Draft genome sequence of phenol degrading Acinetobacter sp. Strain V2, isolated from oil contaminated soil

Abstract We report here the draft genome sequence of Acinetobacter sp. Strain V2 isolated from the oil contaminated soil collected from ENGEN, Amanzimtoti, South Africa. Degradation of phenolic compounds such as phenol, toluene, aniline etc. at 400 ppm in 24 h and oil degrading capability makes this organism an efficient multifunctional bioremediator. Genome sequencing of Acinetobacter spp. V2 was carried out on Illumina HiSeq 2000 platform (performed by the Beijing Genomics Institute [BGI], Shenzhen, China). The data obtained revealed 643 contigs with genome size of 4.0 Mb and G + C content of 38.59%.

Assessment of Genetic Fidelity of in vitro Raised Plants in Swertia chirayita through ISSR, RAPD analysis and Peroxidase Profiling during Organogenesis

ABSTRACT An efficient in vitro regeneration protocol for medicinally important herb Swertia chirayita was developed and the genetic fidelity was assessed using RAPD and ISSR markers. The best shoot regeneration was observed on MS basal supplemented with 1.0 mg/L Benzyl amino purine (BAP) in combination with Indole-3-acetic acid (IAA) (0.5 mg/L) that resulted in the increase by multiplication rate (7.65) with an average of 33.33 numbers of shoots and average shoot length of 2.70 cm. It was further enhanced by the addition of adenine sulfate (0.007%) that resulted in an average of 42 shoots per clum with 4.13 cm of average shoot length and the increase in multiplication fold to 9.75 that further resulted in the reduced use of other cytokinins and auxins. The rooting was nearly 100 % on 1/4 MS augmented with 1.0 mg/L Indole butyric acid with maximum average root length of 5.1cm. Plantlets were successfully acclimatized with 85-90 % survival rate. Ascorbate peroxidase activity increased with the maximum activity during the shoot multiplication. Clonal fidelity has been checked by two marker systems ISSR and RAPD and regenerated plants showed high clonal fidelity.

In vitro anticancer activity of extracts of Mentha Spp. against human cancer cells.

In vitro anticancer potential of methanolic and aqueous extracts of whole plants of Mentha arvensis, M. longifolia, M. spicata and M. viridis at concentration of 100 µg/ml was evaluated against eight human cancer cell lines — A-549, COLO-205, HCT-116, MCF-7, NCI-H322, PC-3, THP-1 and U-87MG from six different origins (breast, colon, glioblastoma, lung, leukemia and prostate) using sulphorhodamine blue (SRB) assay. Methanolic extracts of above-mentioned Mentha Spp. displayed anti-proliferative effect in the range of 70-97% against four human cancer cell lines, namely COLO-205, MCF-7, NCI-H322 and THP-1; however, aqueous extracts were found to be active against HCT-116 and PC-3. The results indicate that Mentha Spp. contain certain constituents with cytotoxic properties which may find use in developing anticancer agents.

In vitro cytotoxic activity of leaves extracts of Holarrhena antidysenterica against some human cancer cell lines.

In vitro cytotoxic potential of extracts (95% and 50% ethanolic extract and hot water extract at concentration of 100 µg/ml) from leaves of Holarrhena antidysenterica was evaluated against fourteen human cancer cell lines — A-549, COLO-205, DU-145, HeLa, HEP-2, IMR-32, KB, MCF-7, NCI-H23, OVCAR-5, SiHa, SK-N-MC, SW-620 and ZR-75-1 from nine different tissues (breast, colon, cervix, CNS, lung, liver, oral, ovary and prostate) using SRB assay. The 95% ethanolic extract displayed maximum anti-proliferative effect in the range of 73-92% against eight human cancer cell lines, while 50% ethanolic extract showed cytotoxic activity in the range of 70-94% against seven human cancer cell lines. However, the hot water extract did not show any activity. Among the fractions of 95% and 50% ethanolic extract, significant cytotoxic activity was found in the chloroform soluble fraction of 95% ethanolic extract at 100 µg/ml; it inhibited the growth in the range of 71-99% of seven human cancer cell lines from five different tissues viz., OVCAR-5 (ovary), HT-29 (colon), SK-N-MC (neuroblastoma), HEP-2 (liver), COLO-205 (colon), NIH-OVCAR-3 (ovary) and A-549 (lung). The cytotoxic activity of chloroform soluble fraction was found to be higher than 5-flurouracil, adriamycin, mitomycin-c and paclitaxel (anticancer drugs used as positive controls). Further in vivo studies and identification of active components from the chloroform fraction and their exact mechanism of action could be useful in designing new anticancer therapeutic agents.

Anti-proliferative effect of leaf extracts of Eucalyptus citriodora against human cancer cells in vitro and in vivo.

Six different extracts from Eucalyptus citriodora leaves were investigated for their anticancer effect. Extracts were prepared using a range of polar and non-polar solvents to leach out maximum active components. Phytochemical analysis of the extracts revealed the presence of anthraquinones, cardiac glycosides, flavonoids, saponins and tannins. Cytotoxic activity of different extracts was tested in vitro against seven human cancer cell lines from seven different tissues, such as SW-620 (colon), HOP-62 (lung), PC-3 (prostate), OVCAR-5 (ovary), HeLa (cervix), IMR-32 (neuroblastoma) and HEP-2 (liver). The ethyl acetate, chloroform and 50% methanolic extract displayed highest anti-proliferative effect in a dose-dependent manner. In vivo anti-tumor activity was evaluated against murine tumor (solid) model of Ehrlich ascites carcinoma and Sarcoma 180. The results showed that ethyl acetate and aqueous extracts suppressed the growth of Ehrlich ascites carcinoma (29.79% and 18.48%, respectively), but showed little growth inhibition in case of Sarcoma 180 (13. 86% and 8.57%, respectively). The activity might be due to the flavonoids, tannins and saponins that are present in all the extracts of the plant. Further investigation is required for the isolation of active principle(s) from the ethyl acetate extract, which has shown significant in vitro and in vivo anticancer potential.

Comparison of transthoracic electrical bioimpedance cardiac output measurement with thermodilution method in post coronary artery bypass graft patients.

Transthoracic electrical bioimpedance (TEB) has been proposed as a non-invasive, continuous, and cost-effective method of cardiac output (CO) measurement. In this prospective, non-randomized, clinical study, we measured CO with NICOMON (Larsen and Toubro Ltd., Mysore, India) and compared it with thermodilution (TD) method in patients after off-pump coronary artery bypass (OPCAB) graft surgery. We also evaluated the effect of ventilation (mechanical and spontaneous) on the measurement of CO by the two methods. Forty-six post-OPCAB patients were studied at five predefined time points during controlled ventilation and at five time points when breathing spontaneously. A total of 230 data pairs of CO were obtained. During controlled ventilation, TD CO values ranged from 2.29 to 6.74 L/min (mean 4.45 ± 0.85 L/min), while TEB CO values ranged from 1.70 to 6.90 L/min (mean 4.43 ± 0.94 L/min). The average correlation (r) was 0.548 (P = 0.0002), accompanied by a bias of 0.015 L/min and precision of 0.859 L/min. In spontaneously breathing patients, TD CO values ranged from 2.66 to 6.92 L/min (mean 4.66 ± 0.76 L/min), while TEB CO values ranged from 3.08 to 6.90 L/min (mean 4.72 ± 0.82 L/min). Their average correlation was relatively poor (r = 0.469, P= 0.002), accompanied by a bias of −0.059 L/min and precision of 0.818 L/min. The overall percent errors between TD CO and TEB CO were 19.3% (during controlled ventilation) and 17.4% (during spontaneous breathing), respectively. To conclude, a fair correlation was found between TD CO and TEB CO measurements among post-OPCAB patients during controlled ventilation. However, the correlation was weak in spontaneously breathing patients.

Cutaneous sporotrichosis of face: polymorphism and reactivation after intralesional triamcinolone.

Cutaneous sporotrichosis, a subcutaneous mycotic infection is caused by the saprophytic, dimorphic fungus Sporothrix schenckii. It commonly presents as lymphocutaneous or fixed cutaneous lesions involving the upper extremities with facial lesions being seen more often in children. The lesions are polymorphic. The therapeutic response to saturated solution of potassium iodide is almost diagnostic. We describe a culture-proven case of cutaneous sporotrichosis of the face mimicking lupus vulgaris initially and basal cell carcinoma later, who did not tolerate potassium iodide and failed to respond to treatment with fluconazole. The patient had reactivation of infection following an infiltration of the scar with triamcinolone acetonide injection. Various other aspects of these unusual phenomena are also discussed.

Cutaneous sarcoidosis: clinical profile of 23 Indian patients.

BACKGROUND: Sarcoidosis is a multisystem disease of undetermined etiology. Indian studies on cutaneous sarcoidosis are not many and mainly comprise case reports. AIMS: This retrospective study was carried out to assess the clinical profile of sarcoidosis patients presenting with cutaneous lesions. METHODS: All histopathologically proven cases of cutaneous sarcoidosis seen consecutively between 1999 and 2004 were studied. Their age, sex, presenting features, evolution of disease and laboratory parameters were analyzed. RESULTS: A total of 23 patients (F:M 15:8) between 31 to 78 years (mean 44.3 years) of age had the mean duration of skin lesions of 1.4 years. Six patients had one to four lesions; two patients each had scar sarcoidosis and angiolupoid and one patient each had recurrent erythema nodosum, leg lymphedema and subcutaneous sarcoidosis. Others showed combination of papules, nodules, plaques and psoriasiform lesions. Peripheral lymph nodes were involved in two patients. Among 10 patients of pulmonary involvement, three had become symptomatic four months to four years after the cutaneous lesions. Routine laboratory investigations including serum calcium estimation were normal in all cases. Serum angiotensin-converting enzyme levels were raised in 3 out of 6 patients. Asymptomatic lytic lesions of digital bones were detected in hand X-ray of one patient. CONCLUSION: Skin lesions of sarcoidosis are like the tip of an iceberg indicating more changes in other organs. The symptomatology and abnormal laboratory results do not necessarily correlate with the severity of cutaneous involvement in general.

Behcet's disease with HIV infection: response to antiretroviral therapy.

The differential diagnosis of oral ulcerations in a patient with AIDS/HIV infection is often challenging to the clinician. While old diseases have appeared in a new garb, many new ones are also being recognized. The association of Behetaet's disease and AIDS/HIV infection has been recently recognized. We present an HIV-positive patient having oro-genital aphthosis conforming to the diagnostic criteria for Behetaet's disease. Erythema nodosum, periphlebitis, erythematous papulopustular lesions, half and half nails, ocular congestion, raised ESR and dimorphic anemia were some other features present. He had low CD4+/CD8+ counts. He had no other HIV-related disease. He responded well to triple anti-retroviral treatment alone. The possible pathomechanism of the occurrence of both diseases is also discussed.
