A highly sensitive, selective, and precise ultra-performance liquid chromatography tandem mass spectrometry method was developed and validated for simultaneous quantification of itraconazole and hydroxy itraconazole in human plasma by a single liquid-liquid extraction step. The precursor to product ion transitions of m/z 705.3/392.3, m/z 721.2/408.3 and m/z 708.2/435.4 were used to detect and quantify itraconazole, hydroxy itraconazole and itraconazole-d3 respectively. The lower limit of quantitation was found to be 0.500 ng/mL for itraconazole and 1.00 ng/mL for hydroxy itraconazole. The mean recoveries for itraconazole and hydroxy itraconazole were found to be 100.045% and 100.021%, respectively. This developed method with a chromatographic run time of 2.0 min was successfully applied to a bioequivalence study of 100 mg itraconazole capsule.

A validated ultra-performance liquid chromatography mass spectrometric method (UPLC-MS/MS) was used for the simultaneous quantitation of candesartan (CN) and hydrochlorothiazide (HCT) in human plasma. The analysis was performed on UPLC-MS/MS system using turbo ion spray interface. Negative ions were measured in multiple reaction monitoring (MRM) mode. The analytes were extracted using a liquid-liquid extraction (LLE) method by using 0.1 mL of plasma volume. The lower limit of quantitation for CN and HCT was 1.00 ng/mL whereas the upper limit of quantitation was 499.15 ng/mL and 601.61 ng/mL for CN and HCT respectively. CN d4 and HCT-13Cd2 were used as the internal standards for CN and HCT respectively. The chromatography was achieved within 2.0 min run time using a C18 Pheno-menex, Gemini NX (100 mm ~ 4.6 mm, 5 mm) column with organic mixture:buffer solution (80:20, v/v) at a flow rate of 0.800 mL/min. The method has been successfully applied to establish the bioequivalence of candesartan cilexetil (CNC) and HCT immediate release tablets with reference product in human subjects.

AIM: To evaluate anti cataract effect of phyllanthus niruri (PN) both in vitro and in vivo galactose induced cataract.METHODS: Aqueous extract of PN was evaluated against galactose-induced cataract both in vitro and in vivo. Galactosaemic cataract was induced in rats by feeding 300g/L galactose diet. PN was administered orally at three-dose levels 75, 150 and 300 mg/kg of body weight. Rat lenses were subjected to osmotic stress in vitro by incorporating galactose (30mmol/L) in the culture medium. The effect of PN (720 and 880μg/mL) on the glutathione (GSH) and polyols levels was studied.RESULTS: PN significantly delayed the onset and progression of cataract in vivo. In addition to the delay in reaching various stages of development of cataract, stage IV did not develop with lower doses till the completion of experimental period. Lenses treated with PN 880μg/mL concentration showed higher levels of GSH and decreased levels of polyols in vitro. In vivo, 75mg/kg significantly delayed the onset and progression of cataract as compared to control.CONCLUSION: PN delayed the process of cataracto-genesis in the experimental models. However, further study is required to extrapolate the use in human beings for the prevention of cataract.

Objectives: Dhat syndrome is a cultural bound syndrome in which affected individuals have morbid pre-occupation with semen loss in their urine and its impact on the body. Previous studies have explored the symptomatology and perception regarding seminal discharge of such patients while there is lacked of literature on the assessment by quacks and practitioner of alternative and complementary practitioners (ACMP). Therefore, in addition to objectives of previous studies, this study explores the reprehensibility of such practitioners as they may not be giving correct advice to such patients. Methods: For duration of three months, this mixed method study was conducted in Rohilkhand Medical College campus; individuals were approached both in and outside the Psychiatric Outpatient Department using purposive sampling procedure. ICD-10 diagnostic criterion was used to include affected individual in the study sample. Subsequently, a semi-structured questionnaire to document their socio-demographic data and symptomatology was used. Further, previous consultation to quack, ACMPs and allopathic practitioners other than psychiatrist and advice given to the patient by them was obtained via in-depth interview. The quantitative data was analyzed through proportions whereas qualitative data via thematic analysis. Results: There were 38 out of 110 with Dhat syndrome. Invariably, they complained of undue concern regarding debilitating effects of seminal discharge and harmful for the body. A total 21.1% had prior consultation to ACMPs and attributing it to masturbation and hot weather. Surprisingly, allopathic practitioners consulted gave incorrect advices. Conclusion: Dhat syndrome affects individuals irrespective of their social and education background. Sex education among the masses and emphasis for awareness of this syndrome among ACMPs and allopathic practitioners other than psychiatrist is necessary to reduce this cultural bound syndrome.

BACKGROUND/AIMS: Pyomyositis is an infective condition with primary involvement of the skeletal muscles. There is sparse recent literature on patients with pyomyositis. METHODS: This study was carried out at emergency services of a tertiary care center located in subtropical area of Indian subcontinent. RESULTS: Sixty-two patients of primary pyomyositis formed the study cohort. Mean age of occurrence was 29.9 ± 14.8 years. There were 54 men. Twelve patients had underlying medical diseases. Muscle pain was seen in all 62 patients. Forty-eight patients (77.4%) had the fever. Most common site of involvement was thigh muscles (n = 29, 46.8%). Forty-nine patients (79%) presented in the suppurative stage of illness. Patients with comorbidities were older (age: median 36 years [interquartile range (IQR), 25 to 47] vs. 24 years [IQR, 16 to 35], p = 0.024), had higher culture positivity with gram-negative organisms (8/9 [88.89%] vs. 6/29 [20.69%], p = 0.001). Importantly, higher number of these patients received inappropriate antibiotics initially. Patients with positive pus culture result had higher complication rate (32/38 [84.21%] vs. 10/18 [55.56%], p = 0.044). Six patients (9.7%) had in-hospital mortality. Lower first-day serum albumin, initial inappropriate antibiotic therapy, and advanced form of the disease at presentation were associated with increased in-hospital mortality. CONCLUSIONS: Primary pyomyositis is not an uncommon disease entity. Patients with comorbidities were more likely to receive initial inappropriate antibiotic therapy. Patients with positive pus culture report had the higher rate of complications. Lower first-day serum albumin, initial inappropriate antibiotic therapy and advanced form of the disease at presentation were associated with increased in-hospital mortality.

Coronavirus disease 2019 (COVID-19) has developed as a pandemic, and it created an outrageous effect on the current healthcare and economic system throughout the globe. To date, there is no appropriate therapeutics or vaccines against the disease. The entire human race is eagerly waiting for the development of new therapeutics or vaccines against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Efforts are being taken to develop vaccines at a rapid rate for fighting against the ongoing pandemic situation. Amongst the various vaccines under consideration, some are either in the preclinical stage or in the clinical stages of development (phase-I, -II, and -III). Even, phase-III trials are being conducted for some repurposed vaccines like Bacillus Calmette–Guérin, polio vaccine, and measlesmumps-rubella. We have highlighted the ongoing clinical trial landscape of the COVID-19 as well as repurposed vaccines. An insight into the current status of the available antigenic epitopes for SARS-CoV-2 and different types of vaccine platforms of COVID-19 vaccines has been discussed. These vaccines are highlighted throughout the world by different news agencies. Moreover, ongoing clinical trials for repurposed vaccines for COVID-19 and critical factors associated with the development of COVID-19 vaccines have also been described.

Difficult femoral nonunion takes account of infective nonunion and aseptic gap nonunion. Limb length discrepancy and nonunion need to be tackled simultaneously. Conventionally Ilizarov ring fixator is in vogue but it has some limitations. To overcome these, monorail fixator is an effective alternative. Persistent good results can be obtained if we can get a perfect anatomical alignment and good regeneration.

PURPOSESubtrochanteric fractures of the femur are being managed successfully with various intramedullary and extramedulary implants with reasonable success. However, these implants require precise placement under image intensifier guidance, which exposes the surgeon to substantial amount of radiation. It also restricts the management of these fractures at peripheral centers where facility of image intensifiers is not available. Keeping this in mind we designed this study to identify if contralateral reversed distal femoral locking plate can be used successfully without the use of image intensifier.

METHODSTwenty-four consecutive patients (18 men and 6 women) with a mean age of 28 years (range 19-47 years) suffering subtrochanteric fractures of the femur underwent open reduction and internal fixation with reversed contralateral distal femoral locking plate. The outcome was assessed at the mean follow-up period of 3.2 years (range 2-4.6 years) using the Harris hip score.

RESULTSTwenty-one fractures united with the primary procedure, with a mean time of consolidation being 11 weeks (range, 9-16 weeks). One patient developed superficial suture line infection, which resolved with oral antibiotics. Another patient had a fall 3 weeks after surgery and broke the plate. Repeat surgery with reversed distal femoral locking compression plate was performed along with bone grafting and the fracture united. Two cases had nonunion, which went in for union after bone grafting. The mean Harris hip score at the time of final follow-up was 90.63 (range 82-97).

CONCLUSIONThe reversed contralateral distal femoral plate is a biomechanically sound implant, which when used for fixation of the subtrochanteric fractures with minimal soft tissue stripping shows results comparable to those achieved by using other extramedullary implants as well as intramedullary devices. The added advantage of this implant is its usability in the absence of an image intensifier.

Nonunion in tibial plateau fractures is very rare. Limited literature is available on Pubmed search on intraarticular tibial nonunion. Most of the cases reported have been following failed surgical treatment and none was neglected fractures. Three patients of isolated and neglected medial tibial plateau nonunion with almost similar demographic profile are reported in this paper. All the three patients were managed by minimally invasive compression fixation using lag screws supplemented with limb realignment procedure of high tibial osteotomy. We discussed the injury mechanism, management and rehabilitation in such cases and reviewed the available literature regarding such a presentation.
