Taboo surrounding cancer has continued to be a stubborn and refractory public health issue especially in South Asian countries. Disparities in cancer care remain ubiquitous. Differences in the manner in which cancer is perceived, addressed, and treated might partly be a result of varying cultural influences. This case report highlights the clinical course of a female patient with neurofibromatosis who later developed a large facial malignant peripheral nerve sheath tumour. The case particularly addresses the catastrophic impact of the 'cancer-related social taboos' on various dimensions of cancer care ranging from primary and secondary prevention to definitive management. The financial issues in low-income to medium-income groups as potential deterrents to optimum treatment have also been highlighted. Approach to the common challenges faced by an oncologist practising in a society plagued by misconceptions about health and disease and potential remedial measures to debunk these myths have also been discussed.A healthy multiparous woman presented at 35 weeks and 4 days' gestation with threatened preterm labour on multiple occasions. An incidental finding of severe hypokalaemia (2.4 mmol/L) was detected on routine blood tests. The cause of this hypokalaemia was not initially obvious. It was eventually linked to overuse of over-the-counter antacids for pregnancy-associated heartburn. The patient was managed with parenteral and then oral electrolyte replacement which corrected a pH of 7.55, bicarbonate of 36.7 mEq/L and a base excess 13.1. In this case report we consider whether hypokalaemia could be linked to uterine irritability and threatened preterm labour, whether antacids were being abused in the context of an eating disorder and the importance of taking a full drug history.We describe a case of a middle-aged woman who presented with progressive jaundice and was suspected to have rebound choledocholithiasis, which was initially managed with balloon extraction through endoscopic retrograde cholangiopancreatography at her first presentation. Healthcare in Pakistan, like many other developing countries, is divided into public and private sectors. The public sector is not always completely free of cost. Patients seeking specialised care in the public sector may find lengthy waiting times for an urgent procedure due to a struggling system and a lack of specialists and technical expertise. Families of many patients find themselves facing 'catastrophic healthcare expenditure', an economic global health quandary much ignored.Pityriasis rubra pilaris (PRP) is a rare dermatosis characterised by hyperkeratotic follicular papules, orange-red scaly plaques and palmoplantar keratoderma. The aetiology of the disease is in most cases unclear and treatment can be challenging. Familial cases of PRP may result from pathogenic variants in the caspase recruitment domain family member 14 (CARD14). We present a case of lifelong PRP in a 70-year-old woman, where genetic testing revealed a heterozygote missense variant c.412G>A, p.(Glu138Lys) in CARD14. Therapy with ustekinumab was initiated with remarkable effect, which improved the patient's quality of life significantly.Communicating bronchopulmonary foregut malformations (CBPFMs) are complex and rare anomalies. Their characteristic feature is an anomalous communication between the respiratory system (trachea, lung or bronchus) on one side and the gastrointestinal tract (oesophagus or stomach) on the other. Though acquired CBPFMs are known, the large majority of them are congenital and single. CBPFMs often go undetected even at surgery and require more than one operation before they are successfully addressed. This is because the symptomatology of CBPFM resembles the more common oesophageal atresia (OA) with tracheoesophageal fistula, wherein it may coexist. We report a patient with OA who had a rare form of CBPFM where the upper lobe of the right lung communicated with the upper oesophagus. This account highlights a novel method of working out the uncertain anatomy, in such cases. There may be associated anomalies of the lung parenchyma and vasculature usually involving the pulmonary arterial supply to the affected lung. Clinical, radiological, endoscopic and pathological characterisation permit precise diagnosis in most instances, with an occasional case that defies definition.Nearly a quarter of the Escherichia coli genome encodes for inner membrane proteins of which approximately a third have unassigned or poorly understood function. We had previously demonstrated that the synergy between the functional roles of the inner membrane-spanning YciB and the inner membrane lipoprotein DcrB, is essential in maintaining cell envelope integrity. In yciB dcrB cells, the abundant outer membrane lipoprotein, Lpp, mislocalizes to the inner membrane where it forms toxic linkages to peptidoglycan. Here, we report that the aberrant localization of Lpp in this double mutant is due to inefficient lipid modification at the first step in lipoprotein maturation. Both Cpx and Rcs signaling systems are upregulated in response to the envelope stress. The phosphatidylglycerol-pre-prolipoprotein diacylglyceryl transferase, Lgt, catalyzes the initial step in lipoprotein maturation. Our results suggest that the attenuation in Lgt-mediated transacylation in the double mutant is not a consequence of lowered phetic lethality underlying the inactivation of two inner membrane proteins, a small integral membrane protein YciB, and a lipoprotein, DcrB, results from the attenuation of the first step of lipoprotein maturation at the inner membrane. We propose that these two inner membrane proteins YciB and DcrB play a role in membrane homeostasis in E. coli and related bacteria.DNA replication is essential for the growth and development of Chlamydia trachomatis, however it is unclear how this process contributes to and is controlled by the pathogen's biphasic lifecycle. GSK-3 assay While inhibitors of transcription, translation, cell division, and glucose-6-phosphate transport all negatively affect chlamydial intracellular development, the effects of directly inhibiting DNA polymerase have never been examined. We isolated a temperature sensitive dnaE mutant (dnaEts ) that exhibits a ∼100-fold reduction in genome copy number at the non-permissive temperature (40°C), but replicates similarly to the parent at the permissive temperature of 37°C. We measured higher ratios of genomic DNA nearer the origin of replication than the terminus in dnaEts at 40°C, indicating that this replication deficiency is due to a defect in DNA polymerase processivity. dnaEts formed fewer and smaller pathogenic vacuoles (inclusions) at 40°C, and the bacteria appeared enlarged and exhibited defects in cell division. The bacteria also lacked both discernable peptidoglycan and polymerized MreB, the major cell division organizing protein in Chlamydia responsible for nascent peptidoglycan biosynthesis.
