An account of the botanical anthelmintics used in traditional veterinary practices in Sahiwal district of Punjab, Pakistan

AIM OF THE STUDY: The present study was aimed at documentation of botanical anthelmintics used in the traditional veterinary practices in Sahiwal district of Punjab, Pakistan. MATERIALS AND METHODS: In rapid rural appraisal, 331 traditional veterinary healers (TVH) were identified as key respondents in the study area followed by participatory rural appraisal for data collection using a well-structured questionnaire. Information was collected through interviews, focused group discussions and field visits over a period of 2 years. RESULTS: A total of 49 traditional recipes, with 41 plant species representing 39 genera and 27 families, were recorded for the treatment of helminthosis in animals. Most frequently used plants (>/=5 times) were Brassica campestris L. and Mallotus philippinensis (Lam.) Muell.-Arg. and most frequently used families (>/=5 times) were Brassicaceae, Euphorbiaceae and Solanaceae. Most frequently used part of the plant was leaves (n=10) followed in order by seeds (n=9), whole fruit (n=5), aerial parts and whole plant (n=4), fruit (n=3), bulb (n=2) and bark, rhizome, stem, stem plus root and twigs (n=1). Five recipes out of 49 (10.2%) contained more than one plant species and rest 44 (89.8%) contained single plant species. CONCLUSIONS: Twenty out of 41 plants (48.78%) are reported for the first time for their traditional use as anthelmintics in Pakistan. Further studies on pharmacokinetics using scientific procedures may prove these plants as promising candidates for their future use as anthelmintics.     

Single-Incision Laparoscopic Cholecystectomy Versus Conventional Laparoscopic Cholecystectomy: Meta-analysis and Systematic Review of Randomized Controlled Trials

Background

The objective of this study was to analyze systematically the randomized, controlled trials that compared single-incision laparoscopic cholecystectomy (SILC) and conventional laparoscopic cholecystectomy (CLC).

Methods

The meta-analysis was conducted according to the Quality of Reporting of Meta-analysis (QUORUM) standards. The included studies were analyzed systematically using the statistical software package RevMan. The summated outcomes were expressed as the risk ratios (RR) for dichotomous variables and standardized mean differences (SMD) for continuous variables.

Results

Eleven randomized trials encompassing 858 patients were retrieved from the electronic databases. In the random effects model, postoperative pain, postoperative complications, length of hospital stay, cosmesis score, conversion rate, and time to return to normal activities were statistically comparable between the two cholecystectomy techniques. SILC was associated with a longer operating time [SMD 0.71; 95?% confidence interval (CI) 0.38, 1.05; z?=?4.18; p?<?0.0001) and an increased requirement for additional port insertion (RR 6.54; 95?% CI 2.19, 19.57; z?=?3.36; p?<?0008). However, there was significant heterogeneity among the trials.

Conclusions

SILC does not offer any advantage over CLC for treating benign gallbladder disorders. CLC may be used assiduously for this purpose.     

An assessment of the apex microarray technology in genotyping patients with Leber congenital amaurosis and early-onset severe retinal dystrophy

PURPOSE: Leber congenital amaurosis (LCA) and early-onset severe retinal dystrophy (EOSRD) are genetically heterogeneous, with 11 genes currently implicated. The LCA chip may be used to interrogate many variants in one hybridization reaction. The purpose of this study was to assess the utility of this technology. METHODS: One hundred fifty-three patients with LCA and EOSRD were screened using an array (Asper Ophthalmics, Tartu, Estonia) containing 344 published disease-causing variants and polymorphisms in eight genes: AIPL1, GUCY2D, CRB1, CRX, RPGRIP1, RPE65, MERTK, and LRAT. One hundred thirty-six probands underwent bidirectional sequencing of the full coding region of the RPE65 gene. The same technique was also used to confirm CRB1 and AIPL1 mutations initially identified with the Apex chip (Asper Ophthalmics). Single nucleotide polymorphism (SNP) analysis within control populations was performed for two variants, P701S and W21R, on the chip for GUCY2D. RESULTS: Of the possible 109,392 interrogations, 3,346 (3.06%) failed on one strand whereas 259 (0.47%) failed on both. The chip reported mutations in 68 (44%) patients; 26 patients had two alleles identified (17%). Direct sequencing of RPE65 showed no discrepancies, whereas sequencing of AIPL1 and CRB1 revealed seven samples called erroneously. The SNP analysis of both GUCY2D variants revealed equal prevalence in the EOSRD panel and the normal population. Subsequent reanalysis, after excluding these polymorphisms, revealed one (18.3%) or two (11.7%) mutations identified in 46 patients. When evaluated by diagnosis, 46% of patients with LCA had one or two mutations identified, compared with 24% of patients with EOSRD. CONCLUSIONS: This approach is a rapid and reasonably low-cost technique for identifying both previously identified mutations and common polymorphisms. The addition of further genes and mutations to the chip will improve its utility, though it is advised that all results be checked by direct sequencing.     

Expression of keratin K2e in cutaneous and oral lesions: association with keratinocyte activation,proliferation, and keratinization

The cytoskeleton in keratinocytes is a complex of highly homologous structural proteins derived from two families of type I and type II polypeptides. Keratin K2e is a type II polypeptide that is expressed in epidermis late in differentiation. Here we report the influence of keratinocyte activation, proliferation, and keratinization on K2e expression in samples of cutaneous and oral lesions. The normal expression of K2e in the upper spinous and granular layers of interfollicular epidermis is increased in keloid scars but showed distinct down-regulation in psoriasis and hypertrophic scars where keratinocytes are known to undergo activation. Unlike normal and psoriatic skin, K2e expression in hypertrophic and keloid scars began in the deepest suprabasal layer. In cutaneous basal and squamous cell carcinomas, K2e was absent in most tumor islands but the overlying epidermis showed strong expression. No significant K2e expression in nonkeratinized or keratinized oral epithelia, including buccal mucosa, lateral border of tongue and gingiva was detected. In oral lichen planus K2e expression was undetectable, but in benign keratoses of lingual mucosa induction of K2e along with K1 and K10 was observed. In mild-to-moderate oral dysplasia with orthokeratinization, K2e was highly expressed compared with parakeratinized areas but in severe dysplasia as well as in oral squamous cell carcinoma, K2e expression was undetectable. Taken together, the data suggest that K2e expression in skin is sensitive to keratinocyte activation but its up-regulation in oral lesions is a reflection of the degree of orthokeratinization.     

Acceptability of micronutrient sprinkles: a new food-based approach for delivering iron to First Nations and Inuit children in Northern Canada

Iron deficiency anemia (IDA) is a significant public health problem among Canadian Aboriginal children. The objectives of this study were to determine the acceptability and safety of microencapsulated-iron sprinkles, a new powdered form of iron packaged in a single-serving sachet for prevention of IDA. A total of 102 non-anemic children aged 4 to 18 months from three communities were randomized to receive sprinkles containing 30 mg Fe/day (NR = 49) or placebo (NR = 53) for six months. To assess acceptability, adherence and side effects were monitored bi-weekly. To assess safety, serum ferritin (SF) concentration and anthropometry were measured at baseline and end. Mean adherence was 59.6 +/- 27.7 percent. There were no differences in adherence, SF, anthropometric status or side effects between groups. Although there were no differences in hemoglobin (Hb) concentration and anemia prevalence from baseline to end and between groups, the Hb curve shifted to the right (increased) for the sprinkles group and to the left (decreased) for the placebo group. Sprinkles may provide a safe and acceptable option to the current standard of care (i.e. ferrous sulphate drops) for the provision of iron in Canadian Aboriginal populations.     

A perception-based study to explore COVID-19 pandemic stress and its factors in Bangladesh

Background and aimsWorldwide the COVID-19 pandemic has accelerated sufferings of mental health and behaviour attitudes of people. Many countries, including Bangladesh, reported suicide as extreme consequences of the psychological burden influenced by COVID-19. The present study explores human stress and its factor influenced by COVID-19 in Bangladesh, which significantly affect the quality of life.MethodsAn online-based questionnaire survey was conducted among 651 adult Bangladeshi populations by capturing socio-demographic information, possible human stress, and consequences of the pandemic. A set of statistical tools such as Pearson's Correlation Matrix (PCM), T-test, Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) were applied to identify the relationship between different factors and influential factors increasing human stress.ResultsMore than 83% of the participants are facing COVID-19 related mental stress, which results in short temper, sleep disorder, and family chaos. PCA and HCA outcomes indicated a significant relationship between the respondents' opinions and human stress factors, which harmonized with the country's existing scenario. PCM results enlighten the relationship between human stress factors and found financial hardship, cutting back daily spending, and food crisis are interconnected together causes stress. Also, hampering students' formal education and future career plans significantly contribute to mental stress.ConclusionBased on the above findings, it's crucial to introduce a time-oriented strategy and implement precaution monitoring plans for Bangladesh. The rescue plan will help people to manage the pandemic and improve mental health to fight against psychological challenges related to COVID-19 and future pandemics.     

Rapidly Progressive Congenital Rhabdomyosarcoma Presenting with Multiple Cutaneous Lesions: An Uncommon Diagnosis and a Therapeutic Challenge

Congenital rhabdomyosarcomas (RMSs) are rare tumors with variable clinical presentations. A 2 month-old, term male neonate (37 weeks, 4 days), weighing 3.2 kg, born to a 24 year-old primigravida, by simple vaginal delivery presented with multiple erythematous papulonodular lesions over his trunk that progressed to his whole body, on the first day of delivery. Prior to conception, his mother was treated for polycystic ovarian disease. On the tenth day, his chest computed tomogram scans revealed multiple, heterogeneously enhancing, bilateral pleural-based soft tissue density nodular lesions, along with multiple soft tissue density lesions, involving skeletal muscles of all his body parts. Microsections from two biopsies (on 10th day and after 2 months) revealed a malignant round cell tumor with cells arranged in a diffuse, solid pattern, comprising embryonal and solid alveolar components. Immunohistochemically, the tumor cells were diffusely positive for desmin, myoD1 and myogenin. Diagnosis of embryonal and alveolar (mixed type) RMS was offered. Further molecular cytogenetic analysis was negative for PAX3-FKHR and PAX7-FKHR. The patient was induced on chemotherapy as per intergroup rhabdomyosarcoma study IV protocol. There was treatment response with near total remission after 8 weeks of treatment. Thereafter, new lesions started appearing that also disappeared after modification of the chemotherapy drugs. However, after 16 months, the baby died of brain metastasis. The present case forms the fourth case report of an aggressive form of a congenital RMS with extensive cutaneous involvement and brain metastasis. A review of previously diagnosed cases of congenital RMSs is discussed herewith.
