    Abstract We describe here an efficient ruthenium-catalyzed C–H bond ortho-arylation of 9-(pyrimidin-2-yl)-9H-carbazole by using boronic acids. This methodology exhibits excellent and high site-selectivity, functional group tolerance and was found to give the desired product in moderate to good yields.

    Abstract The first one pot protocol for the diastereoselective synthesis of oxazolo[2,3-c]isoquinoline was achieved by a metal-free, benzoic acid catalyzed reaction of 1,2,3,4-tetrahydroisoquinoline or trypoline with aldehydes under mild conditions via C–H, C–O bond functionalization. A new approach for the synthesis of highly substituted 1H-pyrrolo[2,1-c][1,4]oxazine was carried out.

    Abstract A simple and highly practical method for the synthesis of 2-N-substituted benzothiazoles has been developed by using nano copper ferrite as a magnetically separable, recyclable catalyst. The present tandem process allows to get access to a wide range of 2-N-substituted benzothiazoles in good to excellent yields by the reaction of benzothiazole with nitrogen nucleophiles in the presence of Cs2CO3 as a base. The nano CuFe2O4 could be recovered and reused with no significant loss of catalytic activity.

    Abstract We report a rare case of idiopathic intracranial hypertension (IIH) with multiple cranial nerve palsies involving cranial nerves VI, VII, IX, and X in a 32-year-old female who had no prior comorbidities. Her condition improved rapidly on a ten-day regimen of acetazolamide and tablet topiramate. IIH should be considered in every patient presenting with persistent headache and multiple cranial nerve abnormalities. This paper also includes a literature review of similar cases.

    Abstract Key clinical message: Colorectal carcinoma (CRC) should be suspected in pediatric patients with a bowel obstruction in an emergency setting. Evidence-based surgical management with chemotherapy is crucial to prevent adverse outcomes.
    Abstract: CRC should be suspected in pediatric patients presenting to the emergency with unspecified abdominal pain. An erect X-ray abdomen and a colonoscopy should be initial diagnostic tests. If colonoscopy raises suspicion of CRC, a biopsy during colonoscopy is indicated. A computed tomography scan of the chest, abdomen, and pelvis will also aid in diagnosis, staging, and planning intervention. In advanced cases, the intervention includes proximal diversion, bypass, and bowel resection with anastomosis. Sometimes postoperative chemotherapy may be required.

    Abstract Purpose: This study aimed to determine normative ranges of static pinch strength as measured with a spring gauge in adults of working age and investigate whether pinch strength is associated with hand hypermobility. A secondary aim was to explore whether the Beighton criteria for hypermobility are associated with hypermobility in joints of the hand during forceful pinching.
    Methods: A convenience sample of healthy men and women aged 18-65 years were recruited for measurement of lateral pinch, 2-point pinch, 3-point pinch, and joint hypermobility according to the Beighton criteria. Regression analysis was used to determine the effect of age, sex, and hypermobility on pinch strength.
    Results: Two hundred and fifty men and 270 women participated in this study. Men were stronger than women at all ages. Lateral and 3-point pinch were greatest for all participants and 2-point pinch was the least strong. There were no statistically significant differences between age groups, but a trend for the lowest pinch strength to occur before the mid-thirties was seen in both sexes. Thirty-eight percent of women and 19% of men were hypermobile; however, these participants statistically insignificant differ in pinch strength compared with other participants. The Beighton criteria corresponded strongly with hypermobility in other joints of the hand as observed and photographed during pinch. Hand dominance did not show clear relationships with pinch strength.
    Conclusions: Normative lateral, 2-point, and 3-point pinch strength data for adults of working age are presented with men having greatest pinch strength at all ages. The Beighton criteria for hypermobility are associated with hypermobility in other joints of the hand.
    Clinical relevance: Benign joint hypermobility is not related to pinch strength. Men have greater pinch strength at all ages than women.

    Abstract: ... had been hospitalized for >24 h, were intensively monitored until discharge for the occurrence ...

    Abstract Background: Neurological disorders are common in the general population and the majority of patients have other chronic diseases, necessitating the use of multiple medications, which increases the incidence of drug-related problems (DRPs). Studies from different countries discovered an average of 0.29-1.45 DRPs per patient admitted into the neurology unit.
    Objectives: To identify common DRPs and to evaluate the impact of clinical pharmacist's interventions in resolving the identified DRPs in patients with neurological disorders.
    Methods: A prospective interventional study was conducted in the Department of Neurology in a tertiary care teaching hospital in Southern India, for a period of six months. Patients aged ≥18 years and had been hospitalized for >24 h, were intensively monitored until discharge for the occurrence of any DRPs and pharmacist interventions were provided. The identified DRPs were classified according to Hepler and Strand's Classification.
    Results: A total of 310 prescriptions were reviewed, of which 174 patients (mean age 45.93 ± 2.49 years) experienced at least one DRP during their hospital stay. The average DRP per patient was found to be 1.75, with drug-drug interactions [254 (83%)] being the predominant DRPs, followed by adverse drug reactions [13 (4%)], and drug duplications [9 (3%)]. Most of the drug-drug interactions were pharmacokinetic [144 (56.69%)]. Hyponatremia [2 (15%)]; and nausea and vomiting [2 (15%)] were most commonly reported ADRs. All 306 DRPs involved active clinical pharmacist intervention, of which [275 (89.87%)] of pharmacists' interventions were accepted, which led to modification of the therapy.
    Conclusion: Monitoring the use of drugs allowed the clinical pharmacist to detect DRPs and to suggest interventions that promote rational drug prescribing, therapy optimization and enhanced patient safety.

    Abstract Endophthalmitis is an ophthalmological emergency requiring timely and appropriate diagnosis and treatment. Microbiological methods of microscopy (Gram's staining) and culture are the current gold standard for organism identification. However, a significant proportion of endophthalmitis remains culture-negative-perhaps the inflammation is non-infectious in origin, results from a novel organism are unidentifiable or because the causative organism is non-culturable often due to pre-treatment with antibiotics. This review outlines the microbiological profile of endophthalmitis, current clinically used methods for organism identification, and the newer molecular techniques of polymerase chain reaction (PCR) and next-generation sequencing (NGS) technology as diagnostic tools for endophthalmitis. They offer the potential to improve organism identification rates and clinical outcomes in infectious diseases, representing an exciting future direction for organism identification in endophthalmitis. Based on the largest ophthalmic hospital in Australia, we highlight the key practical challenges faced by Australian diagnostic laboratories for their use in a clinical setting.
