RESUMO

Investigation on accumulation of cell wall components over critical growth stages will surely provide a new insight into dry matter accumulation studies in rice. An elevated biomass production provides an alternative strategy of yield improvement, which in turn maneuvers the species concerned as potential dual-purpose crop. On that note, present study was carried on 33 early and 39 medium duration rice genotypes. The average cellulose accumulation was 6.51% and 8.17% in early and medium duration genotypes, respectively, at flowering stage, which later on dipped to 1.43% and 3.46%, respectively, at physiological maturity. The gene specific marker MDgsp-5.a exhibited highest estimate of polymorphic information content (PIC), i.e., 0.685, closely followed by MDgsp-6.a with polymorphic information content (PIC) of 0.683. The control genotypes, i.e., Pratap and Mandakini, are grouped under the same cluster, i.e., Cluster-I.A, indicating their inherent genetic divergence from that of potential accumulators pertaining to cellulose accumulation. Pratap and Mandakini failed to produce peaks of conspicuous form at 3342 cm-1 and 1635 cm-1, bearing out by their low performance pertaining to cellulose and lignin accumulation at the later stages of development, respectively. From histochemistry studies, it was observed that the cell walls of sclerenchyma, peripheral vascular bundles, and parenchyma of the culm transections in control genotypes stained lightly than that of prolific accumulator cell walls, thus corroborating the findings of compositional analysis. The variation in cell wall thickening is primarily accounted due to altered carbohydrate accumulation across the growth stages as explored under scanning electron micrograph.

RESUMO

A 25-year-old, 7-month pregnant woman presented with rapidly progressive multiple ulcerated nodules present for 5 months on her left thigh. The lesions began as small red-colored papules, becoming nodular within few days. Initially, she was treated with systemic antibiotics and analgesics, and later a local physician performed incision and drainage. The lesions further increased, becoming indurated and ulcerated. Two months after her delivery, the lesions had extended to the middle of the medial side of her left thigh. On admission, she had a history of fever and weight loss, but there was no trauma. She delivered a full-term healthy baby boy. Past and family history was not significant. Examination revealed 15-20 ill-defined, erythematous, immobile, and irregular nodules of varying sizes, measuring 4 × 5 cm2, and extending from the inguinal region to the middle portion on medial aspect of the left thigh (Figure 1). Some of the nodules ulcerated with yellow color discharge with crusting, attributed to secondary bacterial infection. Multiple palpable and matted inguinal lymph nodes were present in the left inguinal region.

RESUMO

BACKGROUND: Combination of microneedling and chemical peeling is a simple cost-effective treatment for acne scars. OBJECTIVE: To compare efficacy and safety of combining microneedling with 35% glycolic acid (GA) peel versus microneedling with 15% trichloroacetic acid (TCA) peel in facial atrophic acne scars. METHODS: Forty acne scars patients were randomly divided into 2 groups of 20 each. Patients underwent microneedling followed by 35% GA peeling in Group 1 and 15% TCA peeling in Group 2 at 2 weekly intervals. Improvement was graded by Goodman and Baron's qualitative and quantitative global acne scar grading systems, physician's global assessment, and visual analogue scale (VAS). Skin texture was graded by VAS. RESULTS: On comparing qualitative and quantitative acne scar grading within groups, there was significant difference from the baseline. When the two groups were compared for quantitative and qualitative acne scar grading, the difference was statistically not significant at the end of therapy. In VAS, greater number of patients assessed response as excellent and good in Group 1 than in Group 2 indicating better skin texture improvement in Group 1. CONCLUSION: Both combinations were equally efficacious in treating acne scars. Glycolic acid peel delivered additional advantage of improvement in skin texture.

RESUMO

Recently, topical Tranexamic acid (TXA) has been used in melasma management. On detail search of literature, this may be the first study-assessing efficacy on combining of Topical TXA with GA peel in melasma. The aim of this study is to assess efficacy, safety, and improvement in quality of life index on combining 30% GA peel with 5% TXA solution topically in melasma of epidermal type. Sixty patients of epidermal melasma were included in the study and were categorized into two groups: Combination group was treated with 30% GA peel at 2 weekly intervals with 5% TXA solution applied twice daily and Control group was treated with only 30% GA peel every 2 weeks for 12 weeks. Melasma area severity index (MASI) was used for assessing clinical improvement. Hi-MELASQOL and HRQOL scales were used to measure Melasma related quality of life and were compared between both groups. At each visit, adverse effects were noted. A significantly decreasing trend was seen regarding the MASI score when compared within the group, but the difference was statistically not significant between the two groups at 12 weeks. However, significant reduction in MASI score was attained earlier in the combination group than the control group. Similarly, there was significant improvement in Hi-MELASQOL and HRQOL in both the groups, but the difference between them was statistically not significant. Side effects experienced by patients in both groups were trivial and did not require stoppage of therapy. This study concluded that topical TXA with GA peel has comparable result with GA peel alone, but the therapeutic response was achieved in patients of combination group earlier in comparison to control group patients.

RESUMO

BACKGROUND: Both salicylic acid (SA) and trichloroacetic acid (TCA) have proven efficacy with good safety profiles in the treatment of acne vulgaris. OBJECTIVES: This study compared the clinical efficacy and safety of 25% TCA and 30% SA peels in the treatment of mild and moderate acne vulgaris. METHODS: Patients with mild or moderate acne vulgaris were randomized into 2 groups of 25 persons each, and treated with either the TCA peel or the SA peel at 2-week intervals for 12 weeks. Evaluation of active acne was done by individual lesion counts (comedones, papules and pustules) and calculation of the Michaelsson acne score (MAS). RESULTS: Both peels led to significant decrease in individual lesion counts and MAS compared to baseline values, without significant differences between the treatment groups. Thus, the peels had equivalent efficacy against acne vulgaris. The TCA peel was better in treating non-inflammatory lesions, while the SA peel was better for inflammatory lesions, but the differences were not significant. No serious adverse effects were recorded, but more patients in the TCA peel group experienced burning and stinging sensations. CONCLUSION: The efficacy of 25% TCA is comparable to that of 30% SA in mild-to-moderate acne vulgaris, but safety and tolerability were better with the SA peel than TCA peel.

RESUMO

Glycolic acid (GA), lactic acid (LA) and trichloroacetic acid (TCA) peels have been used in various combinations for treating melasma patients, but none of the studies have compared their therapeutic efficacy and improvement in quality of life (QOL) index with these three peeling agents in melasma. Our study aims to compare the clinical efficacy, safety, tolerability and improvement in QOL index between 30% GA, 92% LA, and 15% TCA peeling in epidermal melasma. Ninety patients were divided into three groups with 30 in each. First group was treated with 30% GA peel, second with 92% LA peel, and third with 15% TCA peel at every 2 weeks interval for 12 weeks. Melasma area severity index (MASI) and QOL index (Melasma quality of life and Health related quality of life index) were used for clinical evaluation. Patients were observed for side effects and tolerability. The mean MASI score after therapy was significantly lower in patients treated with GA and TCA peels as compared with the group receiving LA peel. However, there was no significant difference in the mean MASI scoring at 12 weeks between GA peel and TCA peel groups. The improvement in QOL index was higher among patients undergoing GA peel followed by TCA and LA peel. Adverse effects were noted mostly with TCA peels followed by GA and LA peel. Thus, GA and TCA peels were equally efficacious and more effective than LA peels. LA peel had minimum side effects and better tolerability than GA and TCA peels.

RESUMO

Nevus comedonicus and hidradenitis suppurativa (HS) are disorders of the pilosebaceous unit sharing a similar pathogenesis of follicular occlusion. To our knowledge, less than 10 cases of HS-like lesions complicating nevus comedonicus have been reported. We describe a six-year-old female child with congenital linear nevus comedonicus in the left axilla and groin, complicated by recurrent HS-like lesions in the two years prior to presenting to our clinic. After a meticulous review of the literature, we propose a novel term, nevus comedonicus suppurativa, for this clinical entity.

RESUMO

BACKGROUND: Syphilis causes considerable morbidity not only in adults but also in children. Unfortunately, acquired syphilis in children has not received due attention and remains a relatively ignored field. METHODS: This was a retrospective study, in which epidemiologic, clinical, and investigational data were analyzed from medical records of all sexually transmitted infection (STI) cases attending the STI clinic of Pt. B. D. Sharma, PGIMS, Rohtak from January 1992 to November 2018. Children of age ≤14 years with acquired syphilis were studied. RESULTS: Of 9138 STD cases registered from January 1992 to November 2018, 39 were children with acquired syphilis, of whom 22 were males and 17 were females. The majority were in 12-14 years age group (22 cases; 56.41%). A history of sexual abuse could be elicited in 10 patients. Three gave a history of voluntary sexual activity. Examination revealed secondary syphilis in 32, latent syphilis in 6 and only one case of primary chancre. Analysis of incidence of pediatric acquired syphilis cases over three-year intervals during the last 27 years indicated an initial decreasing trend followed by recent slight rise in last 3 years. CONCLUSION: Social inhibitions and reluctance to report child sexual abuse may have led to an underestimate of actual prevalence. The prevalence in the 12- to 14-year age group may indicate emerging trends of promiscuous sexual behavior. The recent rising trend in occurrence of childhood acquired syphilis may mirror the recent resurgence of adult syphilis.

RESUMO

BACKGROUND: Periorbital hyperpigmentation (POH) is a very common, yet unexplored aesthetic condition. Topical therapy is mainstay of treatment which includes chemical peels and other depigmenting agents. AIMS: To compare clinical efficacy, safety, and tolerability of 20% glycolic acid peels, 15% lactic acid peels, and 12% ferulic acid peels in the treatment of constitutional type of periorbital hyperpigmentation in Indian patients. METHODS: Ninety patients of constitutional POH were enrolled for 12 weeks. They were divided into three groups of 30 each. In 1st group 20% glycolic acid peeling, in 2nd group 15% lactic acid peeling and in 3rd group 12% ferulic acid peeling sessions were performed at 3 weekly intervals. Clinical improvement was assessed objectively using POH grading, physician's and patient's global assessment, and patient's global tolerance. RESULTS: Significant improvement in periorbital hyperpigmentation was noted in all the three groups. Physician and patient's global assessment was excellent with glycolic acid peel followed by ferulic acid peel and lactic acid peel. The incidence of side effects in the form of erythema and itching was maximum with glycolic acid followed by lactic acid and least with ferulic acid, which did not necessitate cessation of therapy. CONCLUSION: Glycolic acid produced the best results among the three peels; however, ferulic acid peel emerged as a safe and effective modality for the treatment of POH.

RESUMO

BACKGROUND: Chemical peels have become a popular modality in the treatment of acne vulgaris (AV). Mandelic acid (MA) is a new emerging peeling agent for AV owing to its antibacterial and anti-inflammatory properties. Hence, it is worthwhile to evaluate the effectiveness and safety profile of this newer agent and to compare it with an older established peeling agent, salicylic acid (SA) in the treatment of AV. OBJECTIVE: Comparison between therapeutic efficacy and safety of 45% MA peel with 30% SA peel in Indian patients suffering from mild-to-moderate facial AV. METHODS: A total of 50 patients suffering from mild-to-moderate AV were randomly divided into two groups, with one receiving 30% SA peels and the other receiving 45% MA peels at an interval of 2 weeks for six sessions. Total duration of the study was 12 weeks. Michaelsson acne scores (MAS) and clinical photographs were used to evaluate the efficacy of therapy objectively. Adverse effects of both the agents were also noted at each visit. RESULTS: Both agents showed almost equal efficacy in improving mild-to-moderate AV. Salicylic acid was found better in treating noninflammatory lesions, while MA had an upper hand in treating inflammatory lesions. Overall, there was no significant difference between the two peels in improving MAS and percentage decrease in MAS. However, adverse effects were lesser with MA peels. CONCLUSION: About 45% MA peel was found to be equally effective as 30% SA peel in mild-to-moderate facial AV. However, safety and tolerability of MA peel were better than SA peel.
