The aim of the study was to analyse risk factors, surgical findings, ovarian salvage rate and histology of ovarian mass. We reviewed 81 cases of surgically proven ovarian torsion retrospectively from June 2014 to June 2019 at a tertiary care referral centre in South India. Demographic, clinical and surgical details of all patients were noted from the medical records. Mean age of the patients was 26 years. Most of the patients were nulliparous and had a pre-existing ovarian mass of size >?5 cm. Ovarian salvage rate was 43.2%. Concomitant cystectomy with detorsion was done in 30 patients without increase in blood loss or complications. Extensive necrosis was present in 78.2% of oophorectomy specimens. Most common histology of ovarian mass in cystectomy specimens was simple ovarian cyst.
Mycobacterium tuberculosis (Mtb) is responsible for high mortality rates in many low- and middle-income countries. This infectious disease remains accountable for around 1.4 million deaths yearly. Finding effective control measures against Mtb has become imperative. Vaccination has been regarded as the safe and lasting control measure to curtail the impact of Mtb. This study used the Mtb protein biomarker PE_PGRS17 to design a multi-epitope vaccine. A previous study predicted a strong antigenic property of PE_PGRS17. Immunogenic properties such as antigenicity, toxicity, and allergenicity were predicted for the PE_PGRS17 biomarker, specific B- and T-cell epitope sequences, and the final multiple epitope vaccine (MEV) construct. Algorithmic tools predicted the T- and B-cell epitopes and those that met the immunogenic properties were selected to construct the MEV candidate for predicted vaccine development. The epitopes were joined via linkers and an adjuvant was attached to the terminals of the entire vaccine construct. Immunogenic properties, and physicochemical and structural predictions gave insight into the MEV construct. The assembled vaccine candidate was docked with a receptor and validated using web-based tools. An immune simulation was performed to imitate the immune response after exposure to a dosed administrated predicted MEV subunit. An in silico cloning and codon optimisation gave insight into optimal expression conditions regarding the MEV candidate. In conclusion, the generated MEV construct may potentially emit both cellular and humoral responses which are vital in the development of a peptide-based vaccine against Mtb; nonetheless, further experimental validation is still required.
Mutations in PRSS1 gene namely R122H and N29I cause hereditary pancreatitis. They are autosomal dominant with a high penetrance (80%) reported in North American, North-east Asian, and North European ethnicities. However, the mutations are reportedly absent in Indian, African, and South American ethnicities. We report here for the first time a family from India that is positive for R122H mutation in the PRSS1 gene. The proband is symptomatic with chronic pancreatitis, however, the father although heterozygous for R122H is asymptomatic. 相似文献
AIM: To investigate genetic susceptibility in Indian subjects with non-alcoholic fatty liver disease(NAFLD) by performing a pooled genetic study.METHODS: Study subjects(n = 306) were recruited and categorized into NAFLD and control groups based on ultrasound findings of fatty infiltration. Of the 306 individuals, 156 individuals had fatty infiltration and thus comprised the NAFLD group. One hundred and fifty(n = 150) individuals were normal, without fatty infiltration of the liver, comprising the control group. Blood samples, demographic and anthropometric data from the individuals were collected after obtaining informed consent. Anthropometric data, blood glucose, lipids and liver function tests were estimated using standard methods. Genome wide association stud-ies done to date on NAFLD were identified, 19 single nucleotide polymorphisms(SNPs) were selected from these studies that were reported to be significantly associated with NAFLD and genotyping was performed on the Sequenom platform. Student's t test for continuous variables and χ2 test was applied to variant carriers from both groups. Required corrections were applied as multiple testing was done.RESULTS The mean age of the control group was 39.78 ± 10.83 and the NAFLD group was 36.63 ± 8.20 years. The waist circumference of males and females in the control and NAFLD groups were 80.13 ± 10.35; 81.77 ± 13.65 and 94.09 ± 10.53; 92.53 ± 8.27 respectively. The mean triglyceride and alanine transaminase(ALT) levels in the control and NAFLD groups were 135.18 ± 7.77; 25.39 ± 14.73 and 184.40 ± 84.31; 110.20 ± 67.05 respectively. When χ2 test was applied to the number of individuals carrying the variant risk alleles between the control and NAFLD group, a significant association was seen between rs738409 of the patatin-like phospholipase domain containing 3(PNPLA3) gene(P = 0.001), rs2073080 of the PARVB gene(P = 0.02), rs2143571 of SAMM50 gene(P = 0.05) and rs6487679 of the pregnancy zone protein(PZP) gene(P = 0.01) with the disease. Variant single nucleotide polymorphisms(SNPs) in NCAN and PNPLA3 gene were associated with higher levels of ALT, whereas variant SNPs in APOC3, PNPLA3, EFCAB4 B and COL13A1 were associated with high triglyceride levels. Apart from the above associations, rs2073080, rs343062 and rs6591182 were significantly associated with high BMI; rs2854117 and rs738409 with high triglyceride levels; and rs2073080, rs2143571, rs2228603, rs6487679 and rs738409 with high ALT levels.CONCLUSION: Pooled genetic analysis revealed an association of SNPs in PNPLA3, PARVB, SAMM50 and PZP genes with NAFLD. SNPs in NCAN and PNPLA3gene were associated with higher levels of ALT,whereas variant SNPs in APOC3, PNPLA3, EFCAB4 B and COL13A1 were associated with high triglyceride levels. 相似文献
OBJECTIVE: To raise awareness of a rare but serious adverse effect of a commonly used medication. METHOD: Report of a case. RESULTS: A previously healthy 42-year-old woman presented with acute-onset delirium with psychotic features as a consequence of levofloxacin therapy. Withdrawal of the medication was associated with return of the patient's normal mental status. CONCLUSION: The new quinolone derivatives (levofloxacin, sparfloxacin, grepafloxacin, trovafloxacin, gatifloxacin and moxifloxacin), also called gyrase inhibitors, are known for their potential to cause central nervous system-related adverse effects, including headache, dizziness and insomnia. Risk factors for neurotoxicity include renal insufficiency, underlying central nervous system (CNS) disease and increased CNS penetration of drug. Acute delirium resulting from levofloxacin therapy is an exceedingly rare complication that has been thought to occur more commonly in elderly patients. Here, we describe levofloxacin-induced delirium with psychotic features in a relatively young, otherwise healthy female. 相似文献
The purpose of this retrospective study was to determine long-term functional outcomes and device tolerance achieved in adult patients who chose to undergo an extraosseous talotarsal stabilization procedure HyProCure® for the treatment of flexible talotarsal joint deformity. Eighty-three adult patients participated in this study. Postoperative subjective assessment of device performance was evaluated using Maryland Foot Scores, which were collected at a mean follow-up period of 51 months. The mean postoperative Maryland Foot Score was 88 out of 100; postoperatively, 52% of cases reported complete alleviation of foot pain, 69% of cases had no limitations on their foot functional abilities, and 80% of cases reported complete satisfaction with the appearance of their feet. The implant was removed in 7 out of 117 cases (removal rate: 6%) due to prolonged pain of the anterior talofibular ligament (4 cases), psychogenic reaction (2 cases), and postoperative infection (1 case). The long-term positive subjective outcomes and excellent patient satisfaction obtained in this study may imply that extraosseous talotarsal stabilization was effective in stabilizing the talotarsal joint complex and eliminating excessive abnormal pronation, thus reducing pain and improving quality of life of the patients; it represents a possible treatment option for partial talotarsal dislocation in cases with flexible and reducible deformity. 相似文献
