ABSTRACT
PURPOSE: A low-cost modular external fixator for the lower limb has been developed for global surgery use. The purpose of this study is to assess outcome measures in the first clinical use of the device. METHODS: A prospective cohort study was conducted with patients recruited in two trauma hospitals. Initial clinical procedure data were collected, and patients were followed up every two weeks until 12 weeks or definitive fixation. Follow-up assessed infection, stability, and radiographic outcomes. In addition, patient-reported outcomes and surgeons' feedback on device usability were collected by questionnaires. RESULTS: The external fixator was used on 17 patients. Ten were mono-lateral, five were joint spanning, and two were delta configuration. One patient had a pin site infection at 12-week follow-up. All were stable when tested mechanically and using radiographic assessment, and 53% were converted to definitive fixation. CONCLUSION: The low-cost external fixator developed is appropriate for use in global surgery trauma centres with good clinical outcomes. PROSPECTIVE TRIAL REGISTRATION NUMBER AND DATE: SLCTR/2021/025 (06 Sep 2021).

The use of external fixators (EFs) dates back to 377 BC Hippocrates' time, and it has a wide range of orthopaedic applications. External fixator has expanded its use in the management of fractures and other musculoskeletal conditions. It is widely used all over the world to manage complex musculoskeletal injuries. It has many advantages as compared to internal fixation in some trauma scenarios. However, the cost of the external fixators presents a dilemma to the healthcare system in developing countries. The goals of this review article are to explain the importance of EFs in developing countries in managing fractures, to determine the problems encountered at present during external fixation by developing countries, to identify solutions that could be used to address these issues, expand the use of external fixation into other domains of treatment, the impact of COVID-19 pandemic on fracture management based on existing literature. In conclusion, EFs are very expensive, researches have been conducted to overcome these barriers in developing countries. However, there are limitations in implementing in developing countries. It is important to have affordable and clinically acceptable EFs available in developing countries.
ABSTRACT
Seaweeds are broadly distributed and represent an important source of secondary metabolites (e.g., halogenated compounds, polyphenols) eliciting various pharmacological activities and playing a relevant ecological role in the anti-epibiosis. Importantly, host (as known as basibiont such as algae)-microbe (as known as epibiont such as bacteria) interaction (as known as halobiont) is a driving force for coevolution in the marine environment. Nevertheless, halobionts may be fundamental (harmless) or detrimental (harmful) to the functioning of the host. In addition to biotic factors, abiotic factors (e.g., pH, salinity, temperature, nutrients) regulate halobionts. Spatiotemporal and functional exploration of such dynamic interactions appear crucial. Indeed, environmental stress in a constantly changing ocean may disturb complex mutualistic relations, through mechanisms involving host chemical defense strategies (e.g., secretion of secondary metabolites and antifouling chemicals by quorum sensing). It is worth mentioning that many of bioactive compounds, such as terpenoids, previously attributed to macroalgae are in fact produced or metabolized by their associated microorganisms (e.g., bacteria, fungi, viruses, parasites). Eventually, recent metagenomics analyses suggest that microbes may have acquired seaweed associated genes because of increased seaweed in diets. This article retrospectively reviews pertinent studies on the spatiotemporal and functional seaweed-associated microbiota interactions which can lead to the production of bioactive compounds with high antifouling, theranostic, and biotechnological potential.

INTRODUCTION: Nonpuerperal uterine inversion (NPUI) is a rare clinical problem with diagnostic and surgical challenges. The objective of our study was to review the literature on NPUI and describe causative pathologies, diagnosis, and different surgical options available for treatment. MATERIALS AND METHODS: A comprehensive literature review was carried out on MEDLINE and Google Scholar databases to look for NPUI using the term "non-puerperal uterine inversion," and further went through the cross-references of the published articles. Data are published case reports from 1911 to September 2018. Of the 153 published cases, 133 reports had adequate details of surgery for analysis. These reports were analyzed, concerning the clinical presentation, methods of diagnosis, and surgical treatment. RESULTS: Mean age of the women was 46.3 years (standard deviation: 18, N = 153). Leiomyoma remained the commonest (56.2%) aetiology. While malignancies contributed to 32.02% of cases, 9.2% were idiopathic. High degree of clinical suspicion and identification of unique features on ultrasonography and magnetic resonance imaging enable prompt diagnosis. In cases of uncertainty, laparoscopy or biopsy of the mass was used to confirm the diagnosis. Hysterectomy or repositioning and repair of the uterus are the only treatment options available. The surgical methods implemented were analyzed in three aspects: route of surgical access, method of repositioning, and final surgical procedure undertaken. The majority (48.8%) had only abdominal access, while 27.1% had both abdominal and vaginal access. Haultain procedure was the most useful procedure for reposition (18.0%) of the uterus. The majority (39.7%) required abdominal hysterectomy with or without debulking of the tumour abdominally, while 15.0% had uterine repair after repositioning. We reviewed the different surgical techniques and described and proposed a treatment algorithm. CONCLUSIONS: Fibroids were the commonest cause for NPUI. Malignancies accounted for one-third of cases. A combined abdominal and vaginal approach, followed by hysterectomy or repair after repositioning, seems to be better for nonmalignant cases.
ABSTRACT
The circle of Willis (CW) located at the base of the brain forms an important collateral network to maintain adequate cerebral perfusion, especially in clinical situations requiring compensatory changes in blood flow. Morphopathological changes in the CW may relate to the severity of the symptoms of certain neurodegenerative and cerebrovascular disorders. The purpose of this study was to investigate the CW abnormalities and their clinical importance in ageing brains. The CW was examined macroscopically in 73 formalin-fixed samples to determine the degree of stenosis of each CW component, atherosclerosis of the CW, hypoplasia (threshold diameter < 1 mm), anatomical variations and aneurysms. Age-related neurodegenerative and cerebrovascular pathologies were screened using immunohistopathological techniques on specific neuroanatomical regions based on standard guidelines. The majority of the elderly brains -93 % (68/73) presented at least a single hypoplastic CW component at death. Anatomical variations were mostly identified in communicating arteries, followed by proximal posterior and anterior cerebral arteries. Arterial bifurcations were found to be the predominant sites for cerebral aneurysms. More than 90 % of the elderly brains presented CW atherosclerosis at death. CW abnormalities did not show any strong associations with neurodegenerative pathologies except for an "at risk" significant association observed between Braak's neurofibrillary tangle (NFT) stages 1-VI and CW atherosclerosis grades ≥ mild (p = 0.05). However, a significant association was observed between microscopic infarcts in deep white matter and hypoplasia in communicating arteries with Fisher's exact test (p < 0.05). Overall, CW abnormalities were predominant in the ageing brains, however their relationships to the occurrence and severity of the symptoms of neurodegenerative pathologies were found to be low.

OBJECTIVE: This review summarises the current literature on the role of microRNAs in presbyacusis (age-related hearing loss) and sudden sensorineural hearing loss. METHODS: Medline, PubMed, Web of Science and Embase databases were searched for primary English-language studies, published between 2000 and 2017, which investigated the role of microRNAs in the pathogenesis of presbyacusis or sudden sensorineural hearing loss. Quality of evidence was assessed using the National Institutes of Health quality assessment tool. RESULTS: Nine of 207 identified articles, 6 of good quality, satisfied the review's inclusion criteria. In presbyacusis, microRNAs in pro-apoptotic and autophagy pathways are upregulated, while microRNAs in proliferative and differentiation pathways are downregulated. Evidence for microRNAs having an aetiological role in sudden hearing loss is limited. CONCLUSION: A shift in microRNA expression, leading to reduced cellular activity and impaired inner-ear homeostasis, may contribute to the pathogenesis of presbyacusis.

OBJECTIVE: Recapitulation of the spermatogenesis process in vitro is a tool for studying the biology of germ cells, and may lead to promising therapeutic strategies in the future. In this study, we attempted to transdifferentiate Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) into male germ cells using all-trans retinoic acid and Sertoli cell-conditioned medium. METHODS: Human WJ-MSCs were propagated by the explant culture method, and cells at the second passage were induced with differentiation medium containing all-trans retinoic acid for 2 weeks. Putative germ cells were cultured with Sertoli cell-conditioned medium at 36â for 3 more weeks. RESULTS: The gene expression profile was consistent with the stage-specific development of germ cells. The expression of Oct4 and Plzf (early germ cell markers) was diminished, while Stra8 (a premeiotic marker), Scp3 (a meiotic marker), and Acr and Prm1 (postmeiotic markers) were upregulated during the induction period. In morphological studies, approximately 5% of the cells were secondary spermatocytes that had completed two stages of acrosome formation (the Golgi phase and the cap phase). A few spermatid-like cells that had undergone the initial stage of tail formation were also noted. CONCLUSION: Human WJ-MSCs can be transdifferentiated into more advanced stages of germ cells by a simple two-step induction protocol using retinoic acid and Sertoli cell-conditioned medium.

OBJECTIVES: To compare endometrial thickness following augmentation of ovulation with clomifene (CC) and letrozole and to assess the rate of multi-follicle development and the FSH fluctuations during the stimulated cycles. METHODS: A comparative study was carried out at the infertility clinic of Faculty of Medicine, University of Kelaniya, Sri Lanka. Each arm included 25 participants. They received either 100 mg of CC or 2.5 mg of letrozole per day for 5 days starting from 2nd day of the cycle. The fluctuation of FSH in the follicular phase of the cycle, the endometrial thickness and the number of pre-ovulatory follicles on the day of detecting a mature follicle, were measured. RESULTS: Treatment with letrozole resulted in a smaller rise in the follicular phase FSH, which was shorter in duration than with CC. Also it resulted in a higher mean endometrial thickness at the time of detecting a mature follicle [9.89 (SD=2.02) mm vs. 8.58 (SD=1.32) mm; p=0.021]. Augmentation of ovulation with CC showed a trend towards multi-follicle development compared to letrozole. CONCLUSIONS: This study suggests that letrozole is superior to CC in augmentation of ovulation in terms of endometrial growth and mono-follicle development. However more studies are needed to assess how these differences affect the treatment outcome before it is recommended for clinical use.

PURPOSE: The lack of evidence on the disease burden has been an obstacle for decision-making on introducing pneumococcal vaccines in Sri-Lanka. Hence, the purpose of this study is to determine the incidence of invasive pneumococcal disease among children under five-years of age in Sri-Lanka's Colombo district. METHODS: In a community-based study, using a sample of 2310 children, we identified syndromes associated with pneumococcal disease (pneumonia, meningitis, sepsis). The estimates of annual cumulative incidence of invasive pneumococcal disease were derived by having applied proportions of laboratory confirmed invasive pneumococcal disease among all-cause syndromes associated with pneumococcal infection obtained from the hospital-based invasive bacterial disease sentinel surveillance and findings of the community-based study to population parameters of the district. The estimates of invasive pneumococcal pneumonia and sepsis based on low-sensitive, culture confirmation were adjusted by a correction factor. RESULTS: The annual cumulative incidence of all-cause clinical syndromes associated with pneumococcal disease (pneumonia, meningitis, sepsis) were 1.3, 0.52, 0.39 per 100 children, respectively. The estimate of adjusted, invasive pneumococcal disease cumulative incidence was 206.3 per 100,000 while estimates of pneumococcal pneumonia, meningitis and sepsis cumulative incidence were 147.9, 13.2 and 45.2 per 100,000 under-five children. CONCLUSION: Reasonable estimates of invasive pneumococcal disease could be derived by using incidence of clinical syndromes associated with pneumococcal disease obtained from population-based studies and proportion of pneumococcal infection among all-cause clinical syndromes associated with pneumococcal disease generated from hospital-based sentinel surveillance. These estimates may help informed decision-making on introduction of pneumococcal conjugated vaccine.

RATIONALE: Bacterial flora can be isolated from many semen samples of subfertile males. Bacteriospermia can compromise the outcome of intra uterine insemination (IUI) by contaminating the post-processed sperm sample. OBJECTIVES: The objective of the present study is to determine the efficacy of penicillin and streptomycin in eliminating the bacteria from semen samples in the sperm processing procedure, and to assess the effects of antibiotics on sperm motility, survivability, and pregnancy rates. DESIGN AND SETTINGS: A prospectively controlled study was carried out using couples undergoing IUI with their informed consent. INTERVENTION: Sperm processing using the swim-up technique in penicillin and streptomycin supplemented culture medium. SUBJECTS AND METHODS: Couples were consecutively allocated in two groups for sperm processing (a) Group AB+ (antibiotics supplemented culture medium, n = 33) and (b) Group AB- (antibiotic free culture medium, n = 33). Semen culture was performed before and after sperm processing. Sperm motility was assessed immediately after processing and after 24 h of incubation. RESULTS: Bacterial isolates were found in 20 (60.6%) and 22 (66.1%) of samples before processing in Groups AB+ and AB- respectively. Addition of antibiotics resulted in completely eliminating non-specific bacteria from semen samples without affecting sperm motility. In vitro survival rate of sperm enhanced in AB+ group compared with AB- group (motile sperm after 24 h), 62.21% (standard deviation [SD]: 37.27) versus 41.36% (SD: 30.78), P = 0.012. Pregnancy rate, was comparable between two groups (9% in Group AB+ vs. 6% in Group AB-, P = 0.45). CONCLUSION: Penicillin streptomycin combination could completely eliminate non-specific bacteria from semen samples during sperm processing in this population. The types of antibiotics and dosage used did not seem to have any harmful effects on human sperm.
ABSTRACT
Introduction of human immunization reduced Japanese Encephalitis (JE) cases dramatically in Sri Lanka. However, the increased reporting of adverse events following immunization (AEFI) affected vaccine acceptance by the community. Against this background, we describe the incidence of overall AEFI and incidence and profile of AEFI, thought to be causally related to the mouse-brain derived JE vaccine. A follow-up of 9798 vaccine recipients was performed for a period of two weeks post-vaccination. Parents self-recorded observed signs and symptoms. The self-records were collected by trained supervisors. All monitored children who manifested symptom/s were investigated in details by medical officers experienced in AEFI investigations within two weeks after ending the follow-up period. Using the results of the investigation, the causality assessment was performed. The estimated cumulative incidence rate of overall AEFI was 8.6 children per 100 immunizations. The same for observed AEFI consistent with causal association to the inactivated JE vaccine was 4.3 children (95% CI-3.9-4.7%) per 100 immunizations. The most frequent AEFI was fever (81%). The frequency of high fever (>102 °F) was 26%. Other major AEFI were body ache (22%) vomiting (21%), urticaria (19%), pruritus (5%), and headache (5%). Though 83% of children with AEFI thought to be causally related to the vaccine sought medical care, only 6.6% required hospitalizations. The incidence rate of AEFI in the cohort event monitoring was several-fold higher than that reported through the national AEFI surveillance system. The incidence rate of allergic manifestations among Sri-Lankan children approached what was reported for non-endemic settings and was higher than in other JE endemic populations elsewhere. Contrary to the belief of medical practitioners and the general public, incidence of seizures was low and vaccine related other neurological manifestations were absent.

OBJECTIVES: Aim of this study was to describe the proportion of contributory factors of female infertility in a population that sought fertility treatment. Furthermore, the clinical findings and underlying pathologies associated with ovulatory dysfunction were also sought. METHODS: A cross-sectional study was carried out at the infertility clinic of the North Colombo Teaching Hospital. New clinic attendees were recruited and both partners had a detailed clinical interview. The women underwent a baseline pelvic ultrasound scan, assessment of ovulation and a hormone profile. Tests for tubal patency were carried out when clinically indicated. RESULTS: Ovulatory dysfunction was noted in 53% (n=218). Clinical and investigatory findings associated with ovulatory dysfunction included irregular menstrual cycles, acanthosis nigricans, hirsutism, polycystic ovary syndrome, a LH:FSH ratio of >1, and increased TSH or testosterone levels. Unilateral tubal occlusion was seen in 9.1 % (n=18) while it was bilateral in 1% (n=2). Abnormalities in sexual function were noted in 10.8% (n=56). CONCLUSIONS: Abnormalities in ovulation were common. Clinical findings that could be used to recognise women at risk of ovulatory dysfunction were identified. Abnormalities in sexual function, which are often overlooked in the clinical management of infertility, were seen in over 10% of patients. Tubal factor infertility is rare.

INTRODUCTION: Efficacy and safety of expectant management of first trimester miscarriage are well known, though the patients' perceptions and attitudes are less clear. This study was designed to understand the women's perception of symptoms, acceptability, fertility wishes and care received. METHODS: A qualitative study among 25 women who were allocated to the expectant management arm of a randomised control trial, which compared expectant versus surgical management of incomplete miscarriage, was carried out. Interviews were recorded at the end of two weeks from the initial diagnosis based on five themes, which were transcribed and analysed. RESULTS: Out of the 25 interviewed, two had to undergo surgical evacuation due to failed expectant management. Excessive bleeding was the main concern especially for employed women. Ideas and beliefs of family members influenced the women's experience. Majority preferred expectant management in a possible future event. Many expected to conceive again but preferred to delay a pregnancy even in the absence of any contraindications. Inadequate knowledge of expectant management led to dissatisfaction regarding the care received. CONCLUSIONS: Better understanding on the natural course of events in spontaneous miscarriage will help not only the patient but also the relatives in accepting expectant management of first trimester miscarriage and influence their ideas, beliefs and feelings. Improved health education, counselling, and symptomatic relief are important aspects in improving the overall quality of care.

INTRODUCTION: Incomplete miscarriage is often treated with surgical evacuation in Sri Lanka. Expectant management, which is an alternative treatment, was assessed for efficacy and safety in a local setting. METHODS: Randomised clinical trial of two treatment groups of expectant and surgical management with 71 and 69 participants, respectively, was done at the University Gynaecology Unit of the Colombo North Teaching Hospital, Ragama, from December 2007 to July 2009. Women with incomplete miscarriage at a period of amenorrhoea of < 14 weeks and retained products of conception of < 50mm were included. Expectant management involved in-ward treatment till resolution of heavy bleeding and pain and follow up for two weeks. In surgical treatment, evacuation was undertaken and the patient sent home from hospital after bleeding settled with follow up. The maximum anteroposterior diameter of the endometrial cavity was measured with transvaginal ultrasonography and a diameter < 15mm was considered as complete miscarriage. RESULTS: Expectant management had a treatment success of 90.1% at one week and 94.4% at two weeks. For surgical treatment this was 95.7%. Infection was noted in one subject from the surgical group and none in the expectant group. Fall in the haemoglobin concentration in the two groups was clinically not significant. The expectantly managed group had a shorter hospital stay than the surgically managed group (1.58 vs 2.57 days, p = 0.008). CONCLUSIONS: Expectant management is an effective and safe alternative to surgical evacuation in management of incomplete miscarriage in the local setting. It relieves the burden on the healthcare provider by shortening the hospital stay and avoiding the need for evacuation of retained products of conception under anaesthesia.

CONTEXT: Effects of zinc on male sexual competence are poorly understood. AIM: To study the effects of different doses of zinc on the sexual competence of males using a rat model. MATERIALS AND METHODS: Three subsets (eight in each subset) of sexually experienced adult male rats were supplemented with three different oral doses of zinc sulphate (a daily dose of 1 mg, 5 mg and 10 mg respectively) for two weeks. A subset of eight animals without zinc supplementation was used as the control group Sexual behavior was observed by placing them individually in cages with receptive females. Statistical Analysis : Data analysis was done using SPSS v10 for windows computer software. RESULTS: Supplementation of 5 mg of zinc/day for two weeks led to a prolongation of ejaculatory latency; 711.6 sec. (SEM 85.47) vs. 489.50 sec. (SEM 67.66), P < 0.05 and an increase in number of penile thrusting; 52.80 (SEM 11.28) vs. 26.50 (SEM 6.17), P < 0.05, compared to controls. The same group had elevated prolactin (PRL) and testosterone (T) levels compared to controls at the end of treatment period; PRL- 7.22 ng/dl (SEM 3.68) vs. 2.90 ng/dl (SEM 0.34) and T- 8.21 ng/ml (SEM 6.09) vs. 2.39 ng/ml (SEM 1.79), P < 0.05. In contrast, reduction of libido was evident in the same group, but this effect was not statistically significant ( P > 0.05). However, partner preference index was positive and 5 mg zinc supplementation did not exert a significant adverse effect on the muscle strength and co-ordination. The subset of rats supplemented with 1 mg/day did not show a difference from the control group while supplementation with 10 mg/day led to a reduction of the libido index, number of mounts and intromissions. Conclusions : Zinc therapy improves sexual competence of male rats; the effect is dose dependent. Increase in the T levels is beneficial in this regard. However, increase in PRL is responsible for the reduced libido index. Further studies on pigs and monkeys are needed to evaluate the therapeutic use of zinc in sexual dysfunction.

PURPOSE: To evaluate the compliance of private pharmacies to good pharmacy practice (GPP) in an urban and rural district in Sri Lanka and identify deficiencies with a view to improving supply of safe and effective drugs to consumers. METHODS: Lot quality assurance sampling (LQAS) method was used to determine the number of pharmacies that need to be studied and the threshold limit of defective elements. An inspection of 20 pharmacies in the urban and all 18 pharmacies in the rural district was carried out using a structured checklist. Compliance to seven subsystems of GPP was studied. RESULTS: Storage of drugs, maintenance of cold chain, dispensing and documentation were comprehensively substandard in both districts. Individual items of supervision in registration, physical environment and order of the pharmacy were also found to be substandard in both districts. CONCLUSION: This study shows that the LQAS method can be used to identify inadequate pharmacy services in the community as a whole. There was poor compliance to GPP by the private pharmacies in both districts. There are concerns about the quality of drugs and the safety of private pharmacy services to the community. Some of the deficiencies could be easily corrected by educating the pharmacists and authorised officers, and more effective and streamlined supervision.
