Sterile inflammation via TRPM8 RNA-dependent TLR3-NF-kB/IRF3 activation promotes antitumor immunity in prostate cancer

Inflammation is a common condition of prostate tissue, whose impact on carcinogenesis is highly debated. Microbial colonization is a well-documented cause of a small percentage of prostatitis cases, but it remains unclear what underlies the majority of sterile inflammation reported. Here, androgen- independent fluctuations of PSA expression in prostate cells have lead us to identify a prominent function of the Transient Receptor Potential Cation Channel Subfamily M Member 8 (TRPM8) gene in sterile inflammation. Prostate cells secret TRPM8 RNA into extracellular vesicles (EVs), which primes TLR3/NF-kB-mediated inflammatory signaling after EV endocytosis by epithelial cancer cells. Furthermore, prostate cancer xenografts expressing a translation-defective form of TRPM8 RNA contain less collagen type I in the extracellular matrix, significantly more infiltrating NK cells, and larger necrotic areas as compared to control xenografts. These findings imply sustained, androgen-independent expression of TRPM8 constitutes as a promoter of anticancer innate immunity, which may constitute a clinically relevant condition affecting prostate cancer prognosis.

Characteristics and outcomes of hospitalised inpatients with indwelling urinary catheter-a retrospective study from a large regional hospital in queensland

BACKGROUND

Indwelling urinary catheters (IDCs) are a common invasive device in hospitalised patients. Their use is associated with increased risks of developing catheter associated urinary tract infections (CAUTI), and blood stream infections (BSI).

AIMS

To examine the characteristics and outcomes of adult inpatients with an IDC inserted in hospital and identify risk factors for developing CAUTI and BSI.

METHODS

We performed a retrospective observational study of 430 patients with IDC admitted to medical and surgical units of a leading (tertiary) hospital between Nov 2019 till April 2020. Multiple logistic regression analysis was performed to determine independent risk factors for developing urinary tract infection and blood stream infection.

RESULTS

The prevalence of CAUTI in our study was 7.4%. Results of multiple logistic regression indicated that with each day of IDC in situ, the likelihood of UTI development increased by 9% (OR 1.09; 95% CI 1.00 to 1.18; p = 0.03). Age, gender, and catheter reinsertion were not associated with UTI development.

CONCLUSIONS

Longer duration of IDC was associated with elevated risk of developing CAUTI. CAUTI rates were higher than some of those previously published. There was no statistical significance in frequency of CAUTI between medical and surgical patients. No statistically significant variables that contributed to the development of BSI were found. Interventions targeted at reducing catheter days should be used to improve CAUTI rates.

Periodontitis and Diabetes: How Well the Patients have Knowledge about the Established Interrelationship?

Background Type 2 diabetes is an escalating health problem in Nepal and it holds a strong bidirectional Inter relationship with periodontitis. However, lack of its knowledge and motivation among patients may deteriorate and complicate their condition. Objective To assess knowledge among general population regarding the relation between diabetes and periodontitis and to evaluate the role of dentists and physicians in suggesting the diabetic patients for oral health care. Method A cross-sectional study was conducted among the patients visiting Department of Periodontics, Gandaki Medical College. A total 422 patients were interviewed using a set of pretested questionnaire and at the end they were counselled about the impact of diabetes mellitus on periodontal status and vice versa. Result Majority of the patients 257 (60.9%) had no idea about the interrelation between periodontitis and diabetes mellitus. Almost all the patients 363 (86.02%) assumed that poor oral health cannot increase the risk of developing diabetes and amongst those who had knowledge about this relation, the major source of information was their diabetic friends and relatives 46 (10.9%) and other sources such as syllabus 46 (10.9%). Only handful of patients 30 (7.10%) were informed about the relation by their dentist. Ironically, none of them were provided information about the interrelation by their treating physician. Conclusion Overall, only few participants had knowledge about the bidirectional relation between periodontitis and diabetes. Hence, our findings support the greater need for more targeted and specific health education along with close collaboration between dentists and physicians.

Photochemical internalization (PCI)-mediated activation of CD8 T cells involves antigen uptake and CCR7-mediated transport by migratory dendritic cells to draining lymph nodes

Antigen cross-presentation to cytotoxic CD8⁺ T cells is crucial for the induction of anti-tumor and anti-viral immune responses. Recently, co-encapsulation of photosensitizers and antigens into microspheres and subsequent photochemical internalization (PCI) of antigens in antigen presenting cells has emerged as a promising new strategy for inducing antigen-specific CD8⁺ T cell responses in vitro and in vivo. However, the exact cellular mechanisms have hardly been investigated in vivo, i.e., which cell types take up antigen-loaded microspheres at the site of injection, or in which secondary lymphoid organ does T cell priming occur? We used spray-dried poly(lactic-co-glycolic acid) (PLGA) microspheres loaded with ovalbumin and the photosensitizer tetraphenyl chlorine disulfonate (TPCS_2a) to investigate these processes in vivo. Intravital microscopy and flow cytometric analysis of the murine ear skin revealed that dendritic cells (DCs) take up PLGA microspheres in peripheral tissues. Illumination then caused photoactivation of TPCS_2a and induced local tissue inflammation that enhanced CCR7-dependent migration of microsphere-containing DCs to tissue-draining lymph nodes (LNs), i.e., the site of CD8⁺ T cell priming. The results contribute to a better understanding of the functional mechanism of PCI-mediated vaccination and highlight the importance of an active transport of vaccine microspheres by antigen presenting cells to draining LNs.

Study Of Depression in Elderly: Prevalence and Factors Associated

Introduction: Ageing is a normal phenomenon. Various studies shows that there is a sharp rise in the elderly population in the last few years. Prevalence of depression in elderly is found to around 13% in the community sample in various countries. There is a dearth of study related to psychiatric illness in elderly in Nepal. This study was aimed to find the prevalence of depression in elderly and see for various factors associated with elderly depression. Material And Method: This was a cross-sectional study conducted at Siddharthnagar Municipality, Bhairahawa, Rupandehi. 316 elderly were selected by using systematic random sampling technique. A Semi- structured interview schedule was developed to collect Socio-demographic data. The Short Form Geriatric Depression Scale (SF-GDS) was used to find out the prevalence of depression among elderly people. Ethical Approval was obtained from the Institutional Review Committee, Chitwan Medical College and permission was obtained from Siddharthnagar Municipality, Bhairahawa, Rupandehi. The collected data was entered in Epidata 3.1 and the data was exported and analyzed in IBM SPSS 20. Results: There were a total of 316 samples in this study. The mean age of respondents was 68.47 years of age. Majority of the respondents (54.1%) were female and living in joint Family (72.2%). Almost 45.9% respondents were from upper caste groups, 90.5% of respondents were Hindus. Among the married (100%) respondents, 54.6% of respondents were living with spouse and 3.2% were divorced and separated from spouse. Depression was present in 49.4% of respondents were depressed. Among depressed respondents, 46.7% of respondents were having mild depression, 39.2% moderate depression and 14.1% severe depression. Conclusion: The finding of this study concluded that depression among elderly people was a substantial problem in Siddharthnagar Municipality, Bhairahawa, Rupandehi.

A Rare Case Report on Thoracoomphalopagus

In the present case study we are reporting a case of thoracoomphalopagus conjoined twins. A 24 years old gravida two para 0+1 carrying thoracoomphalopagus conjoined twins was diagnosed by ultrasonography at early second trimester with single placenta attached posteriorly and low lying. The mortality and morbidity of conjoined twins are high so making the early diagnosis with ultrasonographic examination provides the parents a chance to elect for pregnancy termination.

Thyroid disorders in women with dysfunctional uterine bleeding

Background: Thyroid hormones play a key role in the menstrual and reproductive function of women .It is recognized universally that menstrual disturbances may accompany clinical alteration in thyroid function and every clinician has encountered altered menstrual pattern among women suffering from thyroid disorders. The aim of this study was to find the incidence of thyroid disorders in Dysfunctional uterine bleeding and its correlation with menstrual patterns.Materials and Methods: A hospital based cross-sectional study including 75 cases with dysfunctional uterine bleeding attending the OPD of Nobel Medical College, where incidence of thyroid disorder was evaluated along with its correlation with menstrual patterns and histopathology.Results: The incidence of Gynecological OPD attendance due to abnormal uterine bleeding was 3%.and the incidence of thyroid dysfunction was 10.6% with hypothyroidism being the commonest. (9.3%). The commonest menstrual pattern found was menorrhagia/polymenorrhoea in 8 percent.Conclusion: Prevalence of hypothyroidism was more common in DUB. Thus every woman with menstrual irregularities should undergo thyroid assessment and this will ultimately avoid unnecessary intervention like misuse of hormonal treatment and hysterectomy.

Myomectomy Revisited: Experiences in a Teaching Hospital

INTRODUCTION

Uterine myomas are the most common benign tumors of the female reproductive tract with myomectomy being one of the major modalities of the treatment in our set up. The aim of this study was to share the experiences of open myomectomy from a Teaching Hospital.

METHODS

A observational study was conducted from a records of myomectomy cases in the department of Obstetrics and Gynaecology at Nobel Medical College teaching Hospital from June 2014- May 2016.

RESULTS

Total 38 cases of myomectomy were performed during the study period in the women most commong age group being 35-39 years, followed by 30-34. The most common presenting symptoms was abnormal uterine bleeding in 15 (39.47%) followed by mass per abdomen in 10 (26.31%). The most common location of the myoma was intramural followed by subserosal, submucus. Degeneration was also noted in majority of the cases. All the myomectomies were done with Inj Vasopressin injected paracervically except in one case where tourniquet was used. None of the patients had significant post-operative morbidity except fever in the first 24 hours.

CONCLUSIONS

Abdominal myomectomy is a safe and effective procedure for uterine myomas for infertile women in the past but it should be offered to those desiring for uterine preservation irrespective of age and reproductive status.

Pattern of Maxillofacial fracture in Western and Central Nepal: An experience in 3 tertiary level health institutions

BACKGROUND: There are only few studies regarding the pattern and causes of maxillofacial fractures till date in Nepal and no such study in western and central Nepalese population has been conducted. The purpose of this study, therefore, was to describe the causes and the pattern of maxillofacial fractures in western and central part of Nepal over the period of 5 years.MATERIAL AND METHODS A retrospective analysis of maxillofacial fractures was conducted on 328 patients who were treated in the department of maxillofacial surgery. Data was extracted and analyzed based on age, sex, cause of injury and anatomic location.RESULT Young males of 3rd decade of life most commonly sustained the maxillofacial trauma. The commonest site involved was the zygomatic complex (42%) when only mid face fractures was considered and parasymphysis (32%) when only mandible was considered.The most common cause of injuries was road traffic accidents (289 patients; 88.1%) followed by interpersonal violence (25 patients; 7.6 %) and falls accounting for 4.2% of the all injuries. CONCLUSION The findings of this study suggest the need for expansion of the motorway network, ensuring compliance of strict traffic rules and regulations, replacing old vehicles without safety measures and implement school education in alcohol abuse.Journal of College of Medical Sciences-Nepal, 2014, Vol-10, No-3, 8-13

Spontaneous Hemoperitoneum Masquerading Placental Abruption: A Case Report

Hemoperitoneum during pregnancy is a rare but potentially life threatening condition to both mother and fetus. Spontaneous hemoperitoneum may develop from rupture of various abdominal or pelvic viscera like spleen, pancreas and also uterus from the uterine ovarian vessels and rarely from pelvic endometrial implants. It mimics placental abruption having similar clinical presentation like acute abdominal pain, peritonitis, shock and fetal distress or fetal death. We present a case of spontaneous rupture of superficial uterine vessels in third trimester of pregnancy with an objective to share our experience in managing this rare emergency condition having diagnostic dilemmas.

Study of Pathway to Care among Patients with Epilepsy

Objective: To assess the pathway to care among patients with epilepsy up to the tertiary care centre Methods: It is a hospital based, cross-sectional descriptive study of 47 patients visiting BPKIHS psychiatry OPD. Written informed consent was taken from the patients and the primary caretaker. A semi structured Performa was used to record the basic sociodemographic details. Pathway Interview Schedule developed by WHO was used to collect the data. Results Majority (66.0%) of subjects were male. Generalized Seizures were most common (76.6%) type of seizure followed by complex-partial seizure (10.6%). More than half (51.1%) first contacted dhami-jhakri for treatment of their illness. About sixty two percent of patients had the first contact with the treatment provider less than 4 yrs ago. Thirty eight percent subjects sought treatment as per advice from the family members while only 2.1% sought treatment as per advice from the healthcare worker. The most common presenting complaints were sudden loss of consciousness in 89.4%of patients. In majority of patients (57.4%), problem arised ≤ 4yrs back. Significant high numbers of patients (51.1%) were prescribed alternative forms of treatment like herbal medications, talisman, offerings and sacrifices and jhadphook for their presenting problem. About eighty seven percent patients had to travel ≤12 hours for the treatment while 10.7% had to travel a distance of >24 hrs for treatment. The mean duration that one had to travel for seeking treatment was 7.95±14.58 hours. It was found that the mean duration that one patient spend before coming to a hospital for modern treatment was 5.64 months. Conclusions People suffering from epilepsy are still using the traditional healing practices leading to delay in the patient care. These findings call for a comprehensive educational program that can remove the misconcepts regarding the illness.

Coccidioidomycosis is a fungal infection caused by Coccidioides species. The disease has wide clinical presentation and a distinct geographical distribution. We describe two cases of coccidioidomycosis in returned Australian travellers who presented to Nambour Hospital. Knowledge of the international geographical distribution of endemic fungal infections and their clinical manifestations can assist in earlier diagnosis and appropriate management.

Status of tuberculosis in bovine animals raised by tuberculosis infected patients in Western Chitwan, Nepal

INTRODUCTION: Bovine tuberculosis (bTB) is an important public health concern worldwide. This study was conducted to determine the status of bTB in animals raised by tuberculosis patients in Western Chitwan, Nepal. MATERIALS AND METHODS: This cross-sectional study was conducted from August, 2011 to January, 2012. A total of 100 bovines (cattle and buffalo) raised in 60 farms of tuberculosis patients were tested with single intradermal tuberculin test considering various animal factors. Well designed questionnaire survey was taken with 70 tuberculosis patients of same 60 families focusing knowledge, awareness and various practices related to bovine tuberculosis. RESULTS: Overall 15% bovines were positive for tuberculosis (13.6% cattle and 15.4% buffaloes). Age of animal was significantly associated with tuberculosis (p<0.05) while sex and species were not. 24% tuberculosis patients had raw milk consuming habit while very few of them (9%) were aware of zoonotic aspect of bovine tuberculosis. CONCLUSIONS: There is high chance of tuberculosis transmission form animals to humans or vice versa. Further detailed study is needed in large scale with stronger intersectoral collaboration of medical and veterinary health sector to determine the scale of problem and find out prevention and control strategies against zoonotic tuberculosis.

Surgical outcome of pars plana vitrectomy: a retrospective study in a peripheral tertiary eye care centre of Nepal

BACKGROUND

Trans-pars plana vitrectomy (TPPV) is an effective surgical procedure to retain the useful vision in vitreoretinal diseases.

OBJECTIVE

To evaluate the surgical outcome of pars plana vitreoretinal surgery.

STUDY DESIGN

Retrospective non-comparative interventional case series.

MATERIALS AND METHODS

A hospital-based retrospective interventional study of series of cases was carried out in retina clinic of Lumbini Eye Institute, Nepal, over a period of one-and-a-half years. Records of 64 patients who underwent vitreo-retina surgeries were reviewed. Demography, duration of symptoms, risk factors and indications, preoperative and post-operative visual acuity, intra-operative and post-operative complications were analyzed.

OUTCOME MEASUREMENT

The parameters studied were post-operative visual acuity and complications.

RESULTS

Of 64 patients, 61% presented 2 months after the onset of symptoms. Preoperatively, 65.5% had visual acuity of hand motions to 3/60 followed by perception of light only in 26.6%. The main indication for TPPV was vitreous haemorrhage (VH), in 53%. The visual acuity improved to better than 6/60 in patients with VH (68%), whereas, overall, in 72% of the subjects, it improved by 2 lines postoperatively. The commonest intra-operative complications were iatrogenic retinal break (5, 7.8%) at the sclerostomy site.

CONCLUSION

The main indication for TPPV is vitreous haemorrhage. Useful vision can be restored by pars plana vitrectomy in the majority of the patients. Retinal break is the commonest complication of TPPV.

Mesophilic and hyperthermophilic adenylate kinases differ in their tolerance to random fragmentation

The extent to which thermostability influences the location of protein fragmentation sites that allow retention of function is not known. To evaluate this, we used a novel transposase-based approach to create libraries of vectors that express structurally-related fragments of Bacillus subtilis adenylate kinase (BsAK) and Thermotoga neapolitana adenylate kinase (TnAK) with identical modifications at their termini, and we selected for variants in each library that complement the growth of Escherichia coli with a temperature-sensitive adenylate kinase (AK). Mutants created using the hyperthermophilic TnAK were found to support growth with a higher frequency (44%) than those generated from the mesophilic BsAK (6%), and selected TnAK mutants complemented E. coli growth more strongly than homologous BsAK variants. Sequencing of functional clones from each library also identified a greater dispersion of fragmentation sites within TnAK. Nondisruptive fission sites were observed within the AMP binding and core domains of both AK homologs. However, only TnAK contained sites within the lid domain, which undergoes dynamic fluctuations that are critical for catalysis. These findings implicate the flexible lid domain as having an increased sensitivity to fission events at physiological temperatures. In addition, they provide evidence that comparisons of nondisruptive fission sites in homologous proteins could be useful for finding dynamic regions whose conformational fluctuations are important for function, and they show that the discovery of protein fragments that cooperatively function in mesophiles can be aided by the use of thermophilic enzymes as starting points for protein design.

Branch retinal arterial occlusion

Retinal arterial occlusion is an ocular emergency in which visual prognosis is poor mostly due to late presentation of the patient and macular involvement. The casee described, in this report is ane incidence of Branch Retinal Arterial Occlusion in a 22 year old female with grade II Mitral Regurgitation. The patiente presented witha complaint of painless, diminution of vision in the right eyn. She also presented with perception of black shadow in the superior visual fiel n of the same eye5 for five days. There was no significant systemic ord personal history. Her visual acuity at presentation was 6/60 and 6/6 in the right and left eyes,y which did not improve with glasses or pin-hole. Anterior segment including papillary reaction was normal in both eyes while Fundus examination of the right eye revealed retinal whitening inside the inferotemporal vascular arcade that was encroaching foveolar avascular zone. Visual field defect was detected at superonasally inside arhade but Fundus Fluorescence Angiography was normal. An echoycardiograph revealed grade II Mitral Regurgitation. The patient was kept on observation and after two2 days of follow-up, vision in the right eye was improved to 6/6 unaided but visual field defect was remained same.

Self Injurious Behavior in Temporal Lobe Epilepsy

Self-injurious behavior (SIB) or self-mutilating behavior (SMB) is rare but can occur in temporal lobe epilepsy. Such a behavior during seizures is not usually recalled by patient. Here is a case with self mutilating behavior in left temporal lobe epilepsy, presented because of its rare manifestation and diagnostic dilemma. A 19 year old unmarried Muslim student presented to emergency with SMB, guilty rumination and a persecutory delusion. The patient was intermittently confused about place and time. In subsequent assessments, he was found harboring death wishes and suicidal ideation. He transiently had auditory hallucination and thought broadcasting. He episodically tried to harm himself by severely biting only his left ring finger. It was difficult to influence him during such episodes. EEG revealed left temporal lobe seizure. Diagnosis of 'Epilepsy and Organic Psychosis' was made. The patient responded well to Antiepileptic and Antipsychotic medications. Keywords: seizure, self injurious behavior, suicide, temporal epilepsy.

Antimicrobial susceptibility patterns of clinical isolates of Staphylococcus aureus in Nepal

Isolates of Staphylococcus aureus (n = 117) from patients attending a tertiary care centre in western Nepal were tested for susceptibility to penicillin, oxacillin, gentamicin, erythromycin and ciprofloxacin. Eighteen (15.4%) were methicillin-resistant. Susceptibility among methicillin-resistant isolates varied from 0% (penicillin) to 16.6% (erythromycin and gentamicin), but varied among methicillin-susceptible isolates from 39.4% (penicillin) to 97.0% (ciprofloxacin). Fourteen (77.8%) of the methicillin-resistant isolates were resistant to all agents tested. Implementation of an appropriate antibiotic policy would reduce the risk of further development of antimicrobial resistance.

Doctor's role in early detection of diabetic retinopathy and prevention of blindness from its complications

Diabetic retinopathy (DR) is a microangiopathy, which is caused by chronic hyperglycemia, affecting the retinal arterioles, capillaries and venules, complications of which lead to incurable blindness. Approximately 10% of the diabetic population has type I diabetes mellitus (DM) which is diagnosed before the age of 30 years and rest is type II which is diagnosed after the age of 30 years. In UK 2% general population is affected by DM. In developed countries, diabetic retinopathy is an important and leading cause of blindness in working age group where as in developing western countries this figure occupy 12% of the blindness. In developing countries like Nepal, cataract still remains a main cause of blindness and diabetes is not considered as a major problem. However due to a rapid urbanization and modernization of population, diabetes mellitus is becoming an endemic disease and bringing a new challenge in blindness reduction program.

The modern mental health system in Nepal: organizational persistence in the absence of legitimating myths

This paper advances an organizational explanation for the slow pace of modernization of mental health care systems in developing societies. In complement to cultural and political economic explanations of this condition, we suggest that the value of establishing modern systems in developing societies lies in the legitimation such structures provide for indigenous modernizing efforts vis-a-vis both indigenous and external audiences. The system need not meet actual levels of service demand. Its importance is in its symbolic value as an indicator of modernity. The result is a system in "permanent failure". Implications for institutional theory and the growth of modern mental health systems in developing societies are discussed.

Peripheral ulcerative keratitis triggered by bacterial conjunctivitis

Background: Peripheral ulcerative keratitis (PUK) is a disorder consisting of a crescent-shaped destructive inflammation of the perilimbal corneal stroma. Case: We present a case of PUK following acute bacterial conjunctivitis in a 60-year-old lady with a history of on-and-off joint pain for two years. After admission to the hospital, she underwent conjunctival resection and was given topical and oral steroids. She was prescribed hydroxychloroquine after confirming the diagnosis of rheumatoid arthritis with a positive RA factor. Conclusion: This report highlights the role of infection as a triggering agent in the induction of PUK in an otherwise quiescent cornea.
