Perforated Gastric Cancer: A Case Report and Literature Review.

Gastric cancer perforation is a rare but life-threatening complication of gastric cancer. We present the case of a 53-year-old male with acquired immune deficiency syndrome (AIDS) who presented to the emergency department with severe abdominal pain, was found to have an acute abdomen, and was eventually diagnosed with gastric perforation due to metastatic gastric cancer. This case highlights the challenges in diagnosing and managing perforated gastric cancer and discusses the surgical management options, including the use of laparoscopic techniques and the role of chemotherapy, particularly hyperthermic intraperitoneal chemotherapy (HIPEC).

Synchronous Pelvic Schwannoma With Metastatic Prostate Cancer: A Rare Case and Pathology Review.

Schwannomas are benign tumors arising from well-differentiated Schwann cells of peripheral nerves. They are usually found on the limbs, head, and neck. It is uncommon for schwannoma to occur in the pelvis and when it does, it is often diagnosed late. Pelvic schwannoma when diagnosed are often bigger in size (>5 cm) and may present with local symptoms such as constipation and bladder outlet obstruction. We hereby present a patient with concurrent metastatic prostate carcinoma and pelvic schwannoma. The patient is a 57-year-old man initially diagnosed with prostate cancer and was lost to follow-up. One year later, he presented with metastatic prostate disease and bladder outlet obstruction. Further evaluation revealed a concurrent pelvic mass that was increasing in size. The biopsy of this mass was suggestive of schwannoma. It was decided at the multidisciplinary tumor board conference to offer treatment for his metastatic prostate disease and observe the schwannoma. His obstructive symptoms worsened in the face of clinical evidence of regression of his prostatic disease, and it was decided to resect the pelvic mass. The surgery revealed a huge soft tissue mass within the pelvis that was adherent to the bladder, prostate, and rectum. Morphology and immunohistochemistry studies of the pelvic mass confirmed the diagnosis of ancient schwannoma. We hereby highlight the clinical importance of this presentation and the diagnostic and therapeutic dilemma involved in the management of this patient who presented with two pathologic conditions causing similar symptoms but of different prognostic and therapeutic significance.

Detection of enterovirus D68 among children with severe acute respiratory infection in Myanmar.

BACKGROUND: Enterovirus D68 (EV-D68) is an important reemerging pathogen that causes severe acute respiratory infection and acute flaccid paralysis, mainly in children. Since 2014, EV-D68 outbreaks have been reported in the United States, Europe, and east Asia; however, no outbreaks have been reported in southeast Asian countries, including Myanmar, during the previous 10 years. METHODS: EV-D68 was detected in nasopharyngeal swabs from children with acute lower respiratory infections in Myanmar. The samples were previously collected from children aged 1 month to 12 years who had been admitted to the Yankin Children Hospital in Yangon, Myanmar, between May 2017 and January 2019. EV-D68 was detected with a newly developed EV-D68-specific real-time PCR assay. The clade was identified by using a phylogenetic tree created with the Bayesian Markov chain Monte Carlo method. RESULTS: During the study period, nasopharyngeal samples were collected from 570 patients. EV-D68 was detected in 42 samples (7.4 %)-11 samples from 2017 to 31 samples from 2018. The phylogenetic tree revealed that all strains belonged to clade B3, which has been the dominant clade worldwide since 2014. We estimate that ancestors of currently circulating genotypes emerged during the period 1980-2004. CONCLUSIONS: To our knowledge, this is the first report of EV-D68 detection in children with acute lower respiratory infections in Yangon, Myanmar, in 2017-2018. Detection and detailed virologic analyses of EV-D68 in southeast Asia is an important aspect of worldwide surveillance and will likely be useful in better understanding the worldwide epidemiologic profile of EV-D68 infection.

Ending TB in South-East Asia: flagship priority and response transformation.

Over the decades, the global tuberculosis (TB) response has evolved from sanatoria-based treatment to DOTS (Directly Observed Therapy Shortcourse) strategy and the more recent End TB Strategy. The WHO South-East Asia Region, which accounted for 45% of new TB patients and 50% of deaths globally in 2021, is pivotal to the global fight against TB. "Accelerate Efforts to End TB" by 2030 was adopted as a South-East Asia Regional Flagship Priority (RFP) in 2017. This article illustrates intensified and transformed approaches to address the disease burden following the adoption of RFP and new challenges that emerged during the COVID-19 pandemic. TB case notifications improved by 25% and treatment success rates improved by 6% between 2016 and 2019 due to interventions ranging from galvanising political commitments to empowering and engaging communities. Cumulative TB programme budget allocations in 2022 reached US$ 1.4 billion, about two and a half times the budget in 2016. An ambitious Regional Strategic Plan towards ending TB, 2021-2025, identifies priority interventions that will need investments of up to US$ 3 billion a year to fully implement them. Moving forward, countries in the Region need to leverage RFP and take up intensified, people-centred, holistic interventions for prevention, diagnosis, treatment and care of TB with commensurate investments and cross-ministerial and multi-sectoral coordination.

Detection of parechovirus-A in hospitalized children with acute lower respiratory infection in Myanmar, 2017-2018.

Parechovirus-A (PeV-A) causes emerging infection in children, and clinical presentation depends on genotype. The virus has been investigated mainly in developed countries; however, data from developing countries, especially in Asia, are sparse. This study investigated whether PeV-A circulated in children in Myanmar. This retrospective study evaluated PeV-A in nasopharyngeal samples from children aged 1 month to 12 years who were hospitalized with acute lower respiratory infection at Yankin Children Hospital, Yangon, Myanmar, during the period from May 2017 to April 2019. Real-time polymerase chain reaction (PCR) was used to detect PeV-A, and PCR-positive samples were used for genotyping and phylogenetic analysis. In total, 11/570 (1.9%) of samples were positive for PeV-A; 7 were successfully genotyped by sequencing the VP3/VP1 region, as follows: PeV-A1 (n = 4), PeV-A5 (n = 1), PeV-A6 (n = 1), and PeV-A14 (n = 1). Median age was 10.0 months (interquartile range 4.0-12.0 months), and other respiratory viruses were detected in all cases. Phylogenetic analysis showed that all detected PeV-A1 strains were in clade 1 A, which was a minor clade worldwide. Four PeV-A genotypes were detected in Myanmar. The clinical impact of PeV-A in children should be evaluated in future studies.

Single Nucleotide Polymorphism at rs7903146 of Transcription Factor 7-like 2 gene Among Subjects with Type 2 Diabetes Mellitus in Myanmar.

Objectives: To investigate the association between the single nucleotide polymorphism (SNP) rs7903146 in the transcription factor 7-like 2 (TCF7L2) gene and type 2 diabetes mellitus (T2DM) and to examine the impact of this variant on pancreatic beta-cell function in the Myanmar population. Methodology: A case-control study was undertaken in 100 subjects with T2DM and 113 controls. The SNP rs7903146 was genotyped using the allele-specific polymerase chain reaction method. Plasma glucose and serum insulin levels were determined using the enzymatic colorimetric method and ELISA respectively. Beta-cell function was calculated by the HOMA-ß formula. Results: The frequencies of carrier genotypes (CT and TT) were higher in subjects with T2DM than in controls. The minor T alleles of rs7903146 were found to statistically increase type 2 diabetes risk than the C allele with an allelic odds ratio of 2.07 (95% CI 1.39-3.09, p=0.0004). The mean HOMA-ß level of the group with non-carrier genotype (CC) was significantly higher than that of the groups with carrier genotypes (CT and TT) in subjects with T2DM and controls with a p-value of 0.0003 and less than 0.0001, respectively. Conclusion: The rs7903146 variant of the TCF7L2 gene was found to be associated with T2DM and low ß-cell function among Myanmar subjects.

Endobronchial Foreign Bodies Presenting as Intermittent Chest Pain and Productive Cough.

A 51-year-old male presented with intermittent chest pain for one month and productive cough with yellow sputum for seven days. He had a history of chronic kidney disease stage G3, depression, and polysubstance abuse. His chest X-ray revealed mild hazy opacity in the right lower lobe, followed by a chest computed tomography without contrast that indicated multiple nodular opacities in the left mainstem bronchus with clear lungs. The patient underwent flexible bronchoscopy where the left mainstem bronchus was found to be completely occluded by three clear plastic bags, about 1 x 0.5 cm in size containing whitish content consistent with the appearance of crack cocaine. A high index of suspicion is crucial in patients with suspected foreign body aspiration as prompt extraction of foreign bodies may prevent complications.

A Patient With Hemoglobin SC Disease and Acute Ischemic Stroke Presenting With Altered Mental Status.

A 57-year-old woman with a history of hypertension, diabetes mellitus, obesity, asthma, and hemoglobin SC disease presented to the emergency department by her home health aide after she was found having altered mental status. According to her home health aide, the patient was responding with "Ok" to her questions for more than a day. The hemoglobin on admission was 8.5 g/dL. A magnetic resonance imaging (MRI) without contrast of the brain showed acute cortical infarcts superimposed on the old infarct zone. The patient received 1 unit of packed red blood cells and a session of exchange transfusion, in addition to aspirin, clopidogrel, and atorvastatin during the hospital stay. When a patient known to have sickle cell disease presents with acute neurological deficits, the first consideration is usually acute ischemic stroke due to vaso-occlusion in the cerebral vessels. However, it is essential to not overlook other potential causes of acute neurological deficits.

Incidental Finding of Bilateral Acute Pulmonary Emboli in a Patient With Asymptomatic COVID-19 Infection.

A 58-year-old male with a history of hypertension, dyslipidemia, osteoarthritis of both knees, and morbid obesity presented to the emergency department for opioid detoxification. He complained of generalized soreness, anxiety, and difficulty sleeping but denied signs and symptoms suggestive of coronavirus disease 2019 (COVID-19) infection. His COVID-19 polymerase chain reaction (PCR) result came back positive, and his D-dimer level was 5373 ng/mL. A computed tomography pulmonary angiogram showed a moderate burden of bilateral acute pulmonary emboli. He was managed with enoxaparin sodium subcutaneous therapeutic dose for three days, followed by oral apixaban 10 mg twice a day for seven days and then 5 mg twice a day for six months. To date, the rate of venous thromboembolism (VTE) in nonhospitalized patients with COVID-19 has not been reported, and current guidelines do not recommend thromboprophylaxis for these patients.

Multiple splenic infarcts: unusual presentation of hereditary spherocytosis associated with acute Epstein-Barr virus infection.

A 19-year-old African American woman presented to the emergency department with a history of left upper quadrant pain for a week, associated with nausea, malaise, loss of appetite, subjective fevers and chills. Her family history is significant for thalassemia in her maternal aunt, and hereditary spherocytosis in her brother, sister and cousin. A contrast-enhanced CT scan of the abdomen and pelvis revealed massive splenomegaly and multiple splenic infarcts. On the second day of admission, she developed a fever of 103°F. Further evaluation revealed acute Epstein-Barr virus (EBV) infection and hereditary spherocytosis. Her condition improved after 4 days on piperacillin/tazobactam, intravenous fluids, analgesics and antipyretics. Our case report describes a thorough clinical evaluation of a patient with fever, anaemia, massive splenomegaly and multiple splenic infarcts. It highlights the need for careful interpretation of multiple positive IgM results on viral serological testing that often accompanies acute EBV infections.

Single Nucleotide Polymorphism at +276 G>T of the Adiponectin Gene and Plasma Adiponectin Level in Myanmar Type 2 Diabetic Patients.

OBJECTIVE: The aim of the study was to investigate the association between single nucleotide polymorphisms (SNP) at rs 1501299 (SNP+276 G>T) of the adiponectin gene and plasma adiponectin levels in type 2 diabetes mellitus (T2DM) patients in Myanmar. METHODOLOGY: One hundred T2DM patients and 104 non-diabetic subjects were included in this cross-sectional analytical study. Genotype frequencies were determined by polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) method. Plasma adiponectin level was measured by enzyme-linked immunosorbent assay (ELISA). RESULT: Genotype frequencies (GG, GT, TT) of SNP+276 in diabetic patients were 39%, 48% and 13%, respectively. The GT and TT genotypes were more frequent in T2DM patients (OR 1.98, 95% CI, 1.10-3.55; p=0.02 and OR 4.07, 95% CI, 1.34-12.3; p=0.01), respectively. The T allele of SNP+276 was significantly associated with T2DM (OR 1.96, 95% CI, 1.27-3.01; p=0.002). Mean plasma adiponectin level was significantly lower than in T2DM patients (27.41±16.7 µg/mL) compared to non-diabetic subjects (37.19±26.77 µg/mL) (p=0.002). CONCLUSION: SNP+276 at rs 1501299 of the adiponectin gene was associated with type 2 diabetes and low plasma adiponectin levels in this Myanmar population.

Retention and risk factors for attrition in a large public health ART program in Myanmar: a retrospective cohort analysis.

BACKGROUND: The outcomes from an antiretroviral treatment (ART) program within the public sector in Myanmar have not been reported. This study documents retention and the risk factors for attrition in a large ART public health program in Myanmar. METHODS: A retrospective analysis of a cohort of adult patients enrolled in the Integrated HIV Care (IHC) Program between June 2005 and October 2011 and followed up until April 2012 is presented. The primary outcome was attrition (death or loss-follow up); a total of 10,223 patients were included in the 5-year cumulative survival analysis. Overall 5,718 patients were analyzed for the risk factors for attrition using both logistic regression and flexible parametric survival models. RESULT: The mean age was 36 years, 61% of patients were male, and the median follow up was 13.7 months. Overall 8,564 (84%) patients were retained in ART program: 750 (7%) were lost to follow-up and 909 (9%) died. During the 3 years follow-up, 1,542 attritions occurred over 17,524 person years at risk, giving an incidence density of 8.8% per year. The retention rates of participants at 12, 24, 36, 48 and 60 months were 86, 82, 80, 77 and 74% respectively. In multivariate analysis, being male, having high WHO staging, a low CD4 count, being anaemic or having low BMI at baseline were independent risk factors for attrition; tuberculosis (TB) treatment at ART initiation, a prior ART course before program enrollment and literacy were predictors for retention in the program. CONCLUSION: High retention rate of IHC program was documented within the public sector in Myanmar. Early diagnosis of HIV, nutritional support, proper investigation and treatment for patients with low CD4 counts and for those presenting with anaemia are crucial issues towards improvement of HIV program outcomes in resource-limited settings.

TM4SF20 ancestral deletion and susceptibility to a pediatric disorder of early language delay and cerebral white matter hyperintensities.

White matter hyperintensities (WMHs) of the brain are important markers of aging and small-vessel disease. WMHs are rare in healthy children and, when observed, often occur with comorbid neuroinflammatory or vasculitic processes. Here, we describe a complex 4 kb deletion in 2q36.3 that segregates with early childhood communication disorders and WMH in 15 unrelated families predominantly from Southeast Asia. The premature brain aging phenotype with punctate and multifocal WMHs was observed in ~70% of young carrier parents who underwent brain MRI. The complex deletion removes the penultimate exon 3 of TM4SF20, a gene encoding a transmembrane protein of unknown function. Minigene analysis showed that the resultant net loss of an exon introduces a premature stop codon, which, in turn, leads to the generation of a stable protein that fails to target to the plasma membrane and accumulates in the cytoplasm. Finally, we report this deletion to be enriched in individuals of Vietnamese Kinh descent, with an allele frequency of about 1%, embedded in an ancestral haplotype. Our data point to a constellation of early language delay and WMH phenotypes, driven by a likely toxic mechanism of TM4SF20 truncation, and highlight the importance of understanding and managing population-specific low-frequency pathogenic alleles.

Prevalence of hepatitis C and B virus among patients infected with HIV: a cross-sectional analysis of a large HIV care programme in Myanmar.

Co-infection with the hepatitis C virus (HCV) and/or hepatitis B virus (HBV) influences the morbidity and mortality of patients with HIV. A cross sectional analysis was of 11,032 HIV-infected patients enrolled in the Integrated HIV Care Program from May 2005 to April 2012 and Epi-info 3.5 was used to determine the serological prevalence of chronic hepatitis B and hepatitis C. The mean ± standard deviation age of patients was 36 ± 8.4 years (adult cohort) and 7 ± 3 years (paediatric cohort). The sero prevalence of hepatitis B surface antigen, hepatitis C (anti HCV antibodies) and triple infection are 8.7%, 5.3% and 0.35%, respectively. Men who have sex with men are at the highest risk of being co-infected with hepatitis B while intravenous drug users are at the highest risk of being co-infected with hepatitis C. It is important to screen for hepatitis B and C in HIV infected people in order to provide quality care for HIV patients with co-infection.
