An Unusual, Delayed Presentation of a Migrated Intrauterine Contraceptive Device Into the Rectosigmoid Colon.

The current literature suggests that serious complications after intrauterine contraceptive device (IUCD) insertion are rare. We present a rare case of a migrated IUCD into the rectosigmoid colon. A 33-year-old woman (parity one) presented to the emergency department with a three-day history of flank pain, upper urinary tract infection symptoms, and a low-grade fever. Differentials initially included renal colic or pyelonephritis. However, subsequent computed tomography of the kidneys, ureters, and bladder (CT-KUB) and magnetic resonance imaging of the pelvis (MRI-pelvis) showed a migrated IUCD posterior to the uterine body, with both ends closely abutting onto the adjacent proximal rectum. During further history-taking, she reported a past surgical history of an emergency caesarean section five years ago and the insertion of a copper-IUCD six weeks postnatally. She was subsequently referred to the gynaecologists. In view of the involvement of the bowels, the colorectal surgeons were consulted, and the patient was managed by a multidisciplinary team. The patient subsequently underwent diagnostic hysteroscopy, flexible sigmoidoscopy, diagnostic laparoscopy, removal of impacted IUCD, and repair of the rectum. Intraoperatively, her hysteroscopy noted a normal uterus with an intact cavity. Flexible sigmoidoscopy noted the horizontal arm of the IUCD abutting into the lumen of the rectosigmoid region; however, attempted removal with traction was unsuccessful. A partial rectotomy was done eventually to remove the IUCD. Migration of an IUCD is rare, with uterine perforation rates ranging from 0.04% to 0.2%. Albeit a rare complication, this case highlights the need for clinicians to be cognizant of complications arising from IUCD insertion, as symptoms are often non-specific and mild. This case also highlights the importance of a multidisciplinary discussion in the management of a migrated IUCD, which may include gynaecologists, colorectal surgeons, radiologists, and more. Many innovative ways were also discussed regarding the assessment of it, which includes preoperative imaging or endoscopic evaluation. Novel methods of removal of migrated IUCD in the rectosigmoid colon have also been proposed, including manual traction, proctoscopy, rigid sigmoidoscopy, and removal via a snare. They provide an alternative to the traditional diagnostic laparoscopy or laparotomy, thus reducing the need for general anaesthesia or operative intervention. Looking forward, long-term studies can be done to evaluate the need for intervention for asymptomatic patients where the risk of surgery may outweigh the benefits.

Respiratory microorganisms in acute pharyngitis patients: Identification, antibiotic prescription patterns and appropriateness, and antibiotic resistance in private primary care, central Malaysia.

Acute pharyngitis (AP) is a common reason for private primary care consultations, thus providing an avenue for widespread antibiotic intake among the community. However, there is limited data on the antibiotic prescription appropriateness and resistance information in the Malaysian private primary care setting, therefore, this study aimed to investigate the prevalence of isolated viruses and bacteria, antibiotic resistance patterns, antibiotic prescription patterns and appropriateness by general practitioners (GPs) and factors affecting antibiotic resistance and antibiotic prescription patterns. To investigate, a cross-sectional study was conducted among 205 patients presenting with AP symptoms at private primary care clinics in central Malaysia from 3rd January 2016 to 30th November 2016. Throat swabs were collected from 205 AP patients for two purposes: (i) the detection of four common respiratory viruses associated with AP via reverse-transcription real-time PCR (qRT-PCR); and (ii) bacterial identification using matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF MS). Bacterial isolates were then subjected to antibiotic susceptibility screening and McIsaac scoring was calculated post-prescription based on GP selection of criteria. Generalized estimating equations analysis with multiple logistic regression was conducted to identify factors associated with presence of virus and antibiotic prescription. The results showed that 95.1% (195/205) of patients had at least one of the four viruses, with rhinovirus (88.5%) being the most prevalent, followed by adenovirus (74.9%), influenza A virus (4.6%) and enterovirus (2.1%). A total of 862 non-repetitive colonies were isolated from the culture of throat swabs from 205 patients who were positive for bacteria. From a total of 22 genera, Streptococcus constitutes the most prevalent bacteria genus (40.9%), followed by Neisseria (20%), Rothia (13.0%), Staphylococcus (11%) and Klebsiella (4.9%). Only 5 patients carried group A beta-hemolytic streptococci (GABHS). We also report the presence of vancomycin-resistant S. aureus or VRSA (n = 9, 10.1%) among which one isolate is a multidrug-resistant methicillin-resistant S. aureus (MDR-MRSA), while 54.1% (n = 111) were found to carry at least one antibiotic-resistant bacteria species. Application of the McIsaac scoring system indicated that 87.8% (n = 180) of patients should not be prescribed antibiotics as the majority of AP patients in this study had viral pharyngitis. The antibiotic prescription appropriateness by applying post-prescription McIsaac scoring was able to rule out GABHS pharyngitis in this sample with a GABHS culture-positive sensitivity of 40% (n = 2/5) and specificity of 90% (180/200). In conclusion, antibiotic-resistant throat isolates and over-prescription of antibiotics were observed and McIsaac scoring system is effective in guiding GPs to determine occurrences of viral pharyngitis to reduce unnecessary antibiotic prescription.

Comparison of postpartum incontinence outcomes after vacuum-assisted and forceps-assisted deliveries in a tertiary maternity unit.

INTRODUCTION AND HYPOTHESIS: Forceps-assisted deliveries are an established risk factor for pelvic organ prolapse and pelvic floor injury. However, specific comparison of incontinence outcomes between vacuum-assisted and forceps-assisted deliveries are scarce in the literature. We aimed to compare the initial impact of vacuum and forceps deliveries on new-onset urinary and faecal incontinence as well as pelvic floor muscle strength, with the hypothesis that incontinence outcomes were poorer after forceps- than after vacuum-assisted delivery. METHODS: This is a retrospective cohort study of incontinence outcomes in patients who had primary vacuum- or forceps-assisted delivery. The study population included 108 postpartum patients who had undergone operative vaginal delivery (63 vacuum-assisted, 45 forceps-assisted), met the inclusion criteria and attended the postpartum assessment service. Outcomes studied were the presence and severity of symptoms manifesting beyond 1 month postpartum - faecal incontinence and stress, urgency and mixed urinary incontinence - as well as pelvic floor muscle strength scores based on the modified Oxford scale. RESULTS: Prevalence of new-onset urinary and faecal incontinence was 35.6% in the forceps group and 30.2% in the vacuum group. The data suggest that there is no significant difference in the prevalence of new-onset incontinence symptoms (p = 0.70, difference in prevalence [forceps - vacuum]: 5.4%, 95% CI -0.25, +0.15), frequency (p = 0.40) and amount (p = 0.48) of urine leakage or mean muscle strength scores (p = 0.89). CONCLUSION: In our maternity unit, we observed that type of operative vaginal delivery was not associated with significant differences in urinary incontinence and pelvic floor muscle strength outcomes.

Living with COVID-19: The road ahead.

INTRODUCTION: The COVID-19 pandemic has affected the world for more than a year, with multiple waves of infections resulting in morbidity, mortality and disruption to the economy and society. Response measures employed to control it have generally been effective but are unlikely to be sustainable over the long term. METHODS: We examined the evidence for a vaccine-driven COVID-19 exit strategy including academic papers, governmental reports and epidemiological data, and discuss the shift from the current pandemic footing to an endemic approach similar to influenza and other respiratory infectious diseases. RESULTS: A desired endemic state is characterised by a baseline prevalence of infections with a generally mild disease profile that can be sustainably managed by the healthcare system, together with the resumption of near normalcy in human activities. Such an endemic state is attainable for COVID-19 given the promising data around vaccine efficacy, although uncertainty remains around vaccine immunity escape in emergent variants of concern. Maintenance of non-pharmaceutical interventions remains crucial until high vaccination coverage is attained to avoid runaway outbreaks. It may also be worthwhile to de-escalate measures in phases, before standing down most measures for an endemic state. If a variant that substantially evades immunity emerges, it will need to be managed akin to a new disease threat, with pandemic preparedness and response plans. CONCLUSION: An endemic state for COVID-19, characterised by sustainable disease control measures, is likely attainable through vaccination.

Frequent horizontal and mother-to-child transmission may contribute to high prevalence of STLV-1 infection in Japanese macaques.

BACKGROUND: Simian T-cell leukemia virus type 1 (STLV-1) is disseminated among various non-human primate species and is closely related to human T-cell leukemia virus type 1 (HTLV-1), the causative agent of adult T-cell leukemia and HTLV-1-associated myelopathy/tropical spastic paraparesis. Notably, the prevalence of STLV-1 infection in Japanese macaques (JMs) is estimated to be > 60%, much greater than that in other non-human primates; however, the mechanism and mode of STLV-1 transmission remain unknown. The aim of this study is to examine the epidemiological background by which STLV-1 infection is highly prevalent in JMs. RESULTS: The prevalence of STLV-1 in the JMs rearing in our free-range facility reached up to 64% (180/280 JMs) with variation from 55 to 77% among five independent troops. Anti-STLV-1 antibody titers (ABTs) and STLV-1 proviral loads (PVLs) were normally distributed with mean values of 4076 and 0.62%, respectively, which were mostly comparable to those of HTLV-1-infected humans. Our initial hypothesis that some of the macaques might contribute to frequent horizontal STLV-1 transmission as viral super-spreaders was unlikely because of the absence of the macaques exhibiting abnormally high PVLs but poor ABTs. Rather, ABTs and PVLs were statistically correlated (p < 0.0001), indicating that the increasing PVLs led to the greater humoral immune response. Further analyses demonstrated that the STLV-1 prevalence as determined by detection of the proviral DNA was dramatically increased with age; 11%, 31%, and 58% at 0, 1, and 2 years of age, respectively, which was generally consistent with the result of seroprevalence and suggested the frequent incidence of mother-to-child transmission. Moreover, our longitudinal follow-up study indicated that 24 of 28 seronegative JMs during the periods from 2011 to 2012 converted to seropositive (86%) 4 years later; among them, the seroconversion rates of sexually matured (4 years of age and older) macaques and immature macaques (3 years of age and younger) at the beginning of study were comparably high (80% and 89%, respectively), suggesting the frequent incidence of horizontal transmission. CONCLUSIONS: Together with the fact that almost all of the full-adult JMs older than 9 years old were infected with STLV-1, our results of this study demonstrated for the first time that frequent horizontal and mother-to-child transmission may contribute to high prevalence of STLV-1 infection in JMs.

Primary omental pregnancy.

We present a case of primary omental ectopic pregnancy in a 31-year-old woman which was discovered intraoperatively during a diagnostic laparoscopy and subsequently removed via mini-laparotomy. We emphasise the rarity of this diagnosis, and the importance of careful inspection of the abdominal cavity including the omentum should an ectopic pregnancy be suspected when bilateral fallopian tubes and ovaries appear normal during surgical exploration.

Does low-molecular-weight heparin improve live birth rates in pregnant women with thrombophilic disorders? A systematic review.

INTRODUCTION: Pregnancies in women with thrombophilia are associated with a higher risk of obstetric complications. We systematically reviewed the findings of relevant randomised controlled trials (RCTs) with the aim of investigating the effectiveness of low-molecular-weight heparins (LMWHs) in pregnant women with inherited thrombophilic disorders and its effect on the incidence of live births in these patients. METHODS: The MEDLINE-PubMed and Cochrane CENTRAL databases from 2000 to 2010 were searched using a combination of keywords, including low-molecular-weight heparin, enoxaparin, pregnancy, live birth and thrombophilia. Studies were included if they were RCTs assessing the effect of anticoagulant treatment on live birth rates in women with a history of miscarriage without apparent causes other than thrombophilic disorder. Interventions included LMWH, with or without aspirin, aspirin alone or placebo controlled for the prevention of adverse pregnancy outcome. RESULTS: 43 articles with seven RCTs were retrieved following the initial search, of which four studies had to be excluded as they assessed thromboembolic events as the final outcome (n = 1), focused on idiopathic recurrent miscarriages (n = 1), compared efficacy and safety of two doses of enoxaparin (n = 1), and examined patients with or without thrombophilic disorder (n = 1). Pooled data from the remaining three RCTs showed no significant difference in the improvement of live birth rates following LMWH interventions (p = 0.15). CONCLUSION: At present, the use of LMWH in women with inherited thrombophilia with recurrent pregnancy loss is not indicated. Large randomised placebo-controlled trials are further needed to prove the effectiveness of LMWH in these patients.
