Invasive cystic hypersecretory carcinoma of the breast

Cystic hypersecretory carcinoma (CHC) of the breast is a rare variant of ductal carcinoma, characterized by variably sized cysts lined by micropapillary fronds to proliferative pseudostratified columnar epithelium. It includes a spectrum of morphological features ranging from clearly benign cystic hypersecretory hyperplasia (CHH), CHH with atypia to invasive CHC. Only 20 cases of invasive CHC have been reported to date. We report a case of a 49-year-old female who presented with a palpable breast lump and nipple discharge. Gross examination showed variable-sized cysts lined by solid grey white tumors. On microscopic examination, cysts were lined by micropapillary fronds with eosinophilic colloid-like secretion with a focus of invasion. A diagnosis of invasive CHC was made. Since there are limited case reports, our understanding of its biological behavior, prognostic factors, and genetic basis is limited.

Immunoglobin A Deficiency and Squamous Cell Carcinoma With a Rare Presentation as Anal Cancer

Selective immunoglobin A deficiency (IgAD) is the most common immunodeficiency disorder in the western world. Cancer is the most common cause of death in these individuals. Various cases have been reported of squamous cell carcinoma (SCC) in IgAD at sites like skin, oral cavity, and lung. Here we present a rare case of SCC occurring as anal cancer. No other reports to our knowledge describe this rare presentation. A 54-year-old Caucasian woman with asymptomatic partial IgAD presented with a palpable anal mass. Further evaluation showed stage IIIa SCC anal cancer (T1N1M0). Additional workup showed positive human papilloma virus (HPV) serology and positive HPV immunohistochemistry studies. The patient achieved complete response with chemoradiation with her most recent imaging and anorectal exam showing no evidence of cancer recurrence at 3 years follow-up. This case highlights the association between IgAD and malignancy. Although IgAD is the most common primary antibody deficiency, this patient's case presents a rare instance of anal SCC in an IgA-deficient individual. Studies show an association between HPV infection and SCC, but few include IgA-deficient individuals. Patients with IgAD and other immunodeficiencies are at higher risk for HPV infection and therefore may be at a higher risk of SCC. With widespread use of the HPV vaccine, the medical community should be aware of its importance in cancer prevention for these patients. Further studies are needed to evaluate relationships between IgAD, HPV infections, SCC cancer, and the role that the HPV vaccine has in cancer prophylaxis.

Fetal reduction from twin to singleton gestation: A meta-analysis

OBJECTIVE

To evaluate outcomes of fetal reduction in twin pregnancy.

SEARCH STRATEGY

PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Google Scholar were searched from 1980 through December 2020.

SELECTION CRITERIA

Prospective or retrospective studies of pregnant women with twin gestations who had a transabdominal reduction of twin to singleton pregnancy with a comparison group of ongoing twin gestations.

DATA COLLECTION AND ANALYSIS

Outcomes were meta-analyzed only if reported in at least three studies.

MAIN RESULTS

Six studies with a pooled sample of 2867 women with a twin pregnancy of whom 624 underwent 2-to-1 reduction and 2243 did not. In the fetal reduction group, the odds of preterm birth before 34 and 37 weeks of pregnancy were lower by 36% (odds ratio [OR] 0.64, 95% confidence interval [CI] 0.48-0.86, P < 0.003) and 77% (OR 0.23, 95% CI 0.12-0.44, P < 0.001), respectively, than in the control group, and the odds of hypertensive disorders and cesarean delivery were lower by 75% (OR 0.25, 95% CI 0.15-0.43, P < 0.001) and 65% (OR 0.35, 95% CI 0.20-0.62, P < 0.001), respectively.

CONCLUSION

Twin reduction to singleton pregnancy decreased the possibility of preterm birth, hypertensive disorders in pregnancy and cesarean delivery. Sufficiently powered prospective studies are needed to support these findings.

MR Imaging Differences in the Circle of Willis between Healthy Children and Adults

BACKGROUND AND PURPOSE

Asymmetries in the circle of Willis have been associated with several conditions, including migraines and stroke, but they may also be age-dependent. This study examined the impact of age and age-dependent changes in cerebral perfusion on circle of Willis anatomy in healthy children and adults.

MATERIALS AND METHODS

We performed an observational, cross-sectional study of bright and black-blood imaging of the proximal cerebral vasculature using TOF-MRA and T2 sampling perfection with application-optimized contrasts by using different flip angle evolution (T2-SPACE) imaging at the level of the circle of Willis in 23 healthy children and 43 healthy adults (4-74 years of age). We compared arterial diameters measured manually and cerebral perfusion via pseudocontinuous arterial spin-labeling between children and adults.

RESULTS

We found that the summed cross-sectional area of the circle of Willis is larger in children than in adults, though the effect size was smaller with T2-SPACE-based measurements than with TOF-MRA. The circle of Willis is also more symmetric in children, and nonvisualized segments occur more frequently in adults than in children. Moreover, the size and symmetry of the circle of Willis correlate with cerebral perfusion.

CONCLUSIONS

Our results demonstrate that the circle of Willis is different in size and symmetry in healthy children compared with adults, likely associated with developmental changes in cerebral perfusion. Further work is needed to understand why asymmetric vasculature develops in some but not all adults.

Systematic review of health workforce surge capacity during COVID-19 and other viral pandemics

Background

Healthcare decision-makers need comprehensive evidence to mitigate surges in the demand for human resources for health (HRH) during infectious disease outbreaks, in terms of both short- and longer-term impacts. This study aimed to assess the state of the evidence to address HRH surge capacity during COVID-19 and other outbreaks of global significance in the 21st century.

Methods

We systematically searched eight bibliographic databases to extract primary research articles published between 01/2000-06/2020, capturing temporal changes in HRH requirements and responses surrounding viral respiratory infection pandemics. A systems approach was used, considering providers in hospitals, out-of-hospital systems, emergency medical services, and public health. We narratively synthesized the evidence following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) standard.

Results

Of the 1,155 retrieved records, 16 studies met our inclusion criteria; of these, 5 focused on COVID-19, 3 on H1N1, and 8 on a hypothetical pandemic. Different training, mobilization, and redeployment options to address pandemic-time health system capacity were assessed. Few governance scenarios drew on observational HRH data allowing for comparability across contexts. Notable evidence gaps included occupational and psychosocial factors affecting healthcare workers' absenteeism and risk of burnout, gendered considerations of HRH capacity, evaluations in low- and lower-middle income countries, and policy-actionable assessments to inform post-pandemic recovery and sustainability of services for noncommunicable disease management.

Conclusions

This research emphasized the critical need for timely, internationally comparable, and equity-informative HRH data and research to enhance preparedness, response, and recovery policies for this and future pandemics. Full paper is available at: https://doi.org/10.1002/hpm.3137

Key messages

The COVID-19 pandemic has highlighted the critical need for enhanced health workforce data and research, including better tracking of demographics, exposures, infections and deaths of health workers. Although women comprise 70% of the health workforce in many countries, gender-blindness persists in the global literature on health workforce research and governance in public health emergencies./bodyt

639 Emergency Surgical Approach to A Bleeding Pseudoaneurysm Of the Posterior Inferior Pancreaticoduodenal Artery After Failed Embolisation

Background

Pseudoaneurysms of visceral arteries are uncommon, with a prevalence of 0.01% to 0.2%1. Initial treatment is radiological embolisation (RE)2. If this fails, surgical access to the pseudoaneurysm is extremely difficult. They are associated with major complications such as rupture, ischaemia and shock2, with a 20-70% mortality rate3. We report the case of a patient admitted with a life-threatening bleed from an aberrant inferior pancreaticoduodenal artery (IPDA) with failed RE.

Case Summary

A 44-year-old patient presented with right upper quadrant pain, shock and low haemoglobin. His computerised tomography (CT) scan showed a large retroperitoneal haematoma with active bleeding from a 5x6mm IPDA pseudoaneurysm. After resuscitation, access to the IPDA during RE via the coeliac axis and superior mesenteric artery was unsuccessful and he deteriorated. He underwent an emergency laparotomy, which showed the retro-peritoneal haematoma had ruptured into the peritoneal cavity through the transverse mesocolon. Four-quadrant abdominal packing and supra-coeliac manual compression of the aorta was utilised. The right colon was mobilised with full kocherisation of the duodenum. The gastrocolic omentum was divided to enter the lesser sac. The haematoma was evacuated and bleeding branches from the IPDA were suture ligated. He required 26 units of blood throughout admission and underwent 24-hour damage control laparostomy on intensive care. CT mesenteric angiogram post-surgery and re-look laparotomy showed no further active bleeds. He had an uneventful recovery and discharged safely.

Conclusions

RE of visceral artery pseudoaneurysms is challenging. Surgery remains the last resort and should be performed by appropriately trained specialist surgeons.

Noncontrast MRI Protocol for Selected Pediatric Pituitary Endocrinopathies: A Procedure with High Diagnostic Yield and Potential to Reduce Anesthesia and Gadolinium-Based Contrast Exposure

BACKGROUND AND PURPOSE

Although many pediatric neuroradiology practices empirically use noncontrast brain and pituitary MR imaging for evaluation of growth hormone deficiency, central precocious puberty, and short stature, there are currently insufficient published data to support this practice in an evidence-based fashion. Therefore, the use of contrast-enhanced MR imaging for all pediatric pituitary endocrinopathies remains widespread. We evaluated whether noncontrast MR imaging has adequate diagnostic yield for the evaluation of pediatric growth hormone deficiency, central precocious puberty, and short stature.

MATERIALS AND METHODS

Pituitary MR imaging studies obtained for growth hormone deficiency, central precocious puberty, or short stature in patients 0-18 years of age from 2010 to 2019 were analyzed. Separate blinded review of noncontrast images in cases with abnormalities on the original radiology report was performed by 2 subspecialty-trained pediatric neuroradiologists, with discrepancies resolved by consensus.

RESULTS

Of the 134/442 MR imaging studies obtained for growth hormone deficiency, central precocious puberty, or short stature with hypothalamic-pituitary region abnormalities, there was 70% concordance with the original reports on blinded review of noncontrast images. Twenty-two of 40 discrepancies were deemed unrelated to the indication, and 9 cases originally interpreted as possible microadenoma were read as having normal findings on blinded review. Only 9 of 40 discrepancies required contrast for further characterization.

CONCLUSIONS

In our study, most relevant radiologic findings in patients with growth hormone deficiency, central precocious puberty, and short stature were detectable without contrast, providing evidence that contrast can be avoided in routine MR imaging evaluation of these indications. We propose a "rapid noncontrast pituitary" MR imaging protocol for pediatric patients presenting with growth hormone deficiency, central precocious puberty, or short stature, which may increase efficiency and decrease contrast and anesthesia exposure.

Identification of human long noncoding RNAs associated with nonalcoholic fatty liver disease and metabolic homeostasis

A growing number of long noncoding RNAs (lncRNAs) have emerged as vital metabolic regulators. However, most human lncRNAs are nonconserved and highly tissue specific, vastly limiting our ability to identify human lncRNA metabolic regulators (hLMRs). In this study, we established a pipeline to identify putative hLMRs that are metabolically sensitive, disease relevant, and population applicable. We first progressively processed multilevel human transcriptome data to select liver lncRNAs that exhibit highly dynamic expression in the general population, show differential expression in a nonalcoholic fatty liver disease (NAFLD) population, and respond to dietary intervention in a small NAFLD cohort. We then experimentally demonstrated the responsiveness of selected hepatic lncRNAs to defined metabolic milieus in a liver-specific humanized mouse model. Furthermore, by extracting a concise list of protein-coding genes that are persistently correlated with lncRNAs in general and NAFLD populations, we predicted the specific function for each hLMR. Using gain- and loss-of-function approaches in humanized mice as well as ectopic expression in conventional mice, we validated the regulatory role of one nonconserved hLMR in cholesterol metabolism by coordinating with an RNA-binding protein, PTBP1, to modulate the transcription of cholesterol synthesis genes. Our work overcame the heterogeneity intrinsic to human data to enable the efficient identification and functional definition of disease-relevant human lncRNAs in metabolic homeostasis.

Medical publishing: a flawed model in dire need of reform

Recently, in the midst of the Covid-19 pandemic, high-profile retractions of some papers published in prestigious medical journals have highlighted the necessity for structural reform to the current model of medical publishing. We discuss what ails the current system and what can be done to remedy it.

Remission in Cushing's disease is predicted by cortisol burden and its withdrawal following pituitary surgery

AIM

To ascertain the predictors of remission and relapse in patients of Cushing's disease (CD) undergoing pituitary transsphenoidal surgery (TSS).

METHODS

Patients with CD subjected to TSS over 35 years at a tertiary care center were included. Patients were grouped into remission and persistent disease at 1 year after surgery, and were further followed up for relapse. Demographic, clinical, biochemical, histological, radiological and post-operative follow-up parameters were analyzed.

RESULTS

Of the 152 patients of CD, 145 underwent TSS. Remission was achieved in 95 (65.5%) patients at 1 year. Patients in remission had shorter duration of symptoms prior to presentation (p = 0.009), more frequent presence of proximal myopathy (p = 0.038) and a tumor size of < 2.05 cm (p = 0.016) in comparison to those with persistent disease. Post-TSS, immediate post-operative 0800-h cortisol (< 159.85 nmol/L; p = 0.001), histological confirmation of tumor (p = 0.045), duration of glucocorticoid replacement (median 90 days; p = 0.001), non-visualization of tumor on MRI (p = 0.003), new-onset hypogonadism (p = 0.001), 3-month 0800-h cortisol (< 384.9 nmol/L; p = 0.001), resolution of diabetes (p = 0.001) and hypertension (p = 0.001), and recovery of hypothalamic-pituitary-adrenal axis (p = 0.018) favored remission. In logistic regression model, requirement of glucocorticoid replacement (p = 0.033), and resolution of hypertension post-TSS (p = 0.003) predicted remission. None of the parameters could predict relapse.

CONCLUSION

The study could ascertain the predictors of remission in CD. Apart from the tumor characteristics, surgical aspects and low post-operative 0800-h cortisol, the results suggest that baseline clinical parameters, longer glucocorticoid replacement, and resolution of metabolic complications post-TSS predict remission in CD. Long-term follow-up is essential to look for relapse.

Role of optical coherence tomography in Barrett’s esophagus

Traditional endoscopic techniques for Barrett’s esophagus (BE) surveillance relied on factor of probability as endoscopists performed cumbersome random biopsies of low yield. Optical coherence tomography (OCT) is a novel technique based on tissue light interference and is set to break conventional barriers. OCT was initially introduced in ophthalmology but was soon adopted by other areas of medicine. When applied to endoscopy, OCT can render images of the superficial layers of the gastrointestinal tract and is highly sensitive in detecting dysplasia in BE. Volumetric laser endomicroscopy is a second generation OCT endoscope device which is able to identify buried glands after ablation. Addition of artificial intelligence to OCT has rendered it more productive. The newer additions to OCT such as angiogram and laser marking will increase the accuracy of investigation. In spite of the few inevitable drawbacks associated with the technology, it presently outperforms all newer endoscopic techniques for the surveillance of BE.

Serotype and genotype diversity of dengue viruses circulating in India: a multi-centre retrospective study involving the Virus Research Diagnostic Laboratory Network in 2018

OBJECTIVES

A retrospective study was undertaken to investigate the circulating dengue virus (DENV) serotypes and genotypes in India in 2018.

METHODS

In total, 4963 samples referred to virus research diagnostic laboratories (n=21), the Indian Council of Medical Research-National Institute of Virology (ICMR-NIV) and ICMR-NIV field units (n=2) for diagnosis of dengue in 2018 were tested using a real-time reverse transcription polymerase chain reaction assay for the presence of DENV serotypes. Representative samples were sequenced for the envelope (E) gene.

RESULTS

Regional diversity was observed with regard to the dominant circulating serotypes. DENV-2 was found to be the most common serotype in many states. Thrombocytopenia, petechiae and malaise were associated with DENV-2 infection. Phylogenetic analyses of DENV E gene sequences revealed the circulation of genotypes I and V of DENV-1, two lineages of DENV-2 genotype IV, DENV-3 genotype III and DENV-4 genotype I.

CONCLUSIONS

This study found regional differences in the prevalence of circulating DENV serotypes in India, and provides baseline data for continuous molecular surveillance. Molecular surveillance may have implications for predicting large-scale outbreaks of dengue if regional shifts in the predominantly circulating serotypes and genotypes are detected during the early phase of the dengue season.

Evaluation of risk factors for prognosticating blunt trauma chest

<b>Introduction:</b> Blunt trauma chest contributes to significant number of trauma admissions globally and is a cause of major morbidity and mortality. Many scoring systems and risk factors have been defined in past for prognosticating blunt trauma chest but, none is considered to be gold standard. </br> <b>Aim:</b> This study was conducted to reassess the significance of available scoring systems and others indicators of severity in prognosticating blunt trauma chest patients. </br> <b>Materials and Methods:</b> In this prospective observational study from November 2016 till March 2018, 50 patients with age more than 12 years with blunt chest trauma who required hospitalization were included. Nine risk factors were assessed namely- age of the patient, duration of presentation after trauma, number of ribs fractured, bilateral thoracic injury, evidence of lung contusion, associated extra thoracic injury, need for mechanical ventilation, Revised trauma Score (RTS) and Modified Early Warning Sign Score (MEWS). Severity of blunt thoracic trauma was assessed on following outcomes-SIRS, ARDS and Death. The inferences were drawn with the use of statistical software package SPSS v22.0. </br> <b>Results:</b> The age of 50 patients included in our study with a range of 15 to 76 years, the median age was 35.5 years. Statistically significant association was observed between occurrence of SIRS and multiple ribs fractured (p-value- 0.049), associated extra-thoracic injury (p-value-0.016) and higher MEWS score (p-value-0.025). ARDS occurrence was statistically significantly associated with all the risk factors except age.Death occurred more in patients with delayed duration of presentation to hospital (p-value <0.001), multiple ribs fractured (p-value-0.001), bilateral thoracic injury(p-value<0.001), associated extra-thoracic injury (p-value-0.004), patients who required ventilatory support (p-value<0.001), low RTS (p-value-0.006) and high MEWS (p-value-0.005) on admission. This association was found statistically significant. </br> <b>Conclusion:</b> High MEWS, associated extra-thoracic injuries and multiple rib fractured can very well predict poor outcome in terms of SIRS, ARDS and death. Aggressive treatment protocols should be established for better outcome in these patients with blunt trauma chest.

Physiologic Specialization and Genetic Differentiation of Puccinia triticina Causing Leaf Rust of Wheat on the Indian Subcontinent During 2016 to 2019

Wheat is the second most cultivated cereal crop in the world and is an important crop in India. Leaf (brown) rust, caused by Puccinia triticina, was the most prevalent among the three rusts found in all the wheat-growing areas of India, Bhutan, and Nepal during 2016 to 2019. Leaf rust samples from wheat crops in these countries were pathotyped using the wheat differential genotypes and binomial Indian system of nomenclature. To facilitate international communication, each pathotype identified was also tested using the North American differentials. A total of 33 pathotypes were identified from 1,086 samples, including three new pathotypes: 61R47 (162-5 = KHTPM) and 93R49 (49 = NHKTN) from India and 93R57 (20-1 = NHKTN) from Nepal. Two pathotypes, 121R60-1 (77-9/52 = MHTKL) and 121R63-1 (77-5 = THTTM), accounted for 79.46% of the population. Virulence on Lr19 was identified in 0.27% of the samples from Nepal only. The proportion of pathotype 121R60-1 (77-9 = MHTKL) increased to 57.55% during these years. Virulence was not observed on Lr9, Lr24, Lr25, Lr28, Lr32, Lr39, Lr45, and Lr47 in the population of the Indian subcontinent. Eighteen polymorphic simple sequence repeat (SSR) primer pairs tested on the isolates amplified 48 alleles with an average of 2.66 alleles per primer pair. Based on SSR genotyping, these pathotypes could be grouped into two clades with another two subclades each. Many of the Lr genes present in Indian wheat germplasm (Lr1, Lr3a, Lr10, Lr11, Lr14a, Lr15, Lr16, Lr17, Lr20, Lr23, and Lr26) were ineffective for a majority of pathotypes. Most of these varieties possessed a high degree of leaf rust resistance. The field resistance of wheat varieties could be attributed to the interaction of genes, unknown resistance, or adult plant resistance.

Primary hyperparathyroidism in pregnancy: observations from the Indian PHPT registry

PURPOSE

To present the data on primary hyperparathyroidism (PHPT) in pregnancy from India obtained from a large database maintained over 15 years.

METHODS

We retrieved data of all women with gestational PHPT from the Indian PHPT registry between July 2005 and January 2020, and compared their clinical, biochemical, and other characteristics with age-matched non-pregnant women with PHPT.

RESULTS

Out of 386 women, eight had gestational PHPT (2.1%). The common presenting manifestations were acute pancreatitis (50%) and renal stone disease (50%); two were asymptomatic. Five women (62.5%) had a history of prior miscarriages. Seven patients (88%) had preeclampsia during the present gestation. Serum calcium and intact parathyroid hormone (iPTH) were not statistically different from the age-matched non-pregnant PHPT group. Six patients with mild-to-moderate hypercalcemia were medically managed with hydration with/without cinacalcet while one patient underwent percutaneous ethanol ablation of the parathyroid adenoma; none underwent surgery during pregnancy. Mean serum calcium maintained from treatment initiation till delivery was 10.5 ± 0.4 mg/dl. One patient had spontaneous preterm delivery at 36 weeks; the remaining patients had normal vaginal delivery at term. None had severe preeclampsia/eclampsia. Fetal outcomes included low birth weight in three newborns (37.5%); two of them had hypocalcemic seizures.

CONCLUSION

The prevalence of gestational PHPT was 2.1% in this largest Indian PHPT cohort, which is higher than that reported from the West (< 1%). Gestational PHPT can lead to preeclampsia and miscarriage. Pregnant PHPT patients with mild-to-moderate hypercalcemia can be managed with hydration/cinacalcet; however, long-term safety data and large-scale randomized controlled trials are required.

Pancreatic adenocarcinoma: A review of recent paradigms and advances in epidemiology, clinical diagnosis and management

Pancreatic cancer is one of the dreaded malignancies for both the patient and the clinician. The five-year survival rate of pancreatic adenocarcinoma (PDA) is as low as 2% despite multimodality treatment even in the best hands. As per the Global Cancer Observatory of the International Agency for Research in Cancer estimates of pancreatic cancer, by 2040, a 61.7% increase is expected in the total number of cases globally. With the widespread availability of next-generation sequencing, the entire genome of the tumors is being sequenced regularly, providing insight into their pathogenesis. As invasive PDA arises from pancreatic intraepithelial neoplasia and mucinous neoplasm and intraductal papillary neoplasm, screening for them can be beneficial as the disease is curable with resection at an early stage. Routine preoperative biliary drainage has no role in patients suffering from PDA with obstructive jaundice. If performed, metallic stents are preferred over plastic ones. Minimally invasive procedures are preferred to open procedures as they have less morbidity. The duct-to-mucosa technique for pancreaticojejunostomy is presently widely practiced. The role of intraperitoneal drains after surgery for PDA is controversial. Neoadjuvant chemoradiotherapy has been proven to have a significant role both in locally advanced as well as in resectable PDA. Many new regimens and drugs have been added in the arsenal of chemoradiotherapy for metastatic disease. The roles of immunotherapy and gene therapy in PDA are being investigated. This review article is intended to improve the understanding of the readers with respect to the latest updates of PDA, which may help to trigger new research ideas and make better management decisions.

A Rare Case of Aneurysmal Bone Cyst - Navicular Bone Treated by Intralesional Sclerotherapy Agent Polidocanol

Introduction:

Aneurysmal bone cyst (ABC) is an intraosseous arteriovenous malformation, usually treated by surgical excision but with higher recurrence rates. The occurrence of this lesion in navicular bone is a rare entity. Repetitive sclerotherapy using 3% polidocanol is a minimally invasive, safer method of treatment for ABCs.

Methods:

A patient of ABC of the navicular bone precisely diagnosed through X-ray, MRI, and biopsy was given periodic injections of 4 ml of 3% polidocanol under aseptic precautions from April 2018 to July 2018. A total of four injections given at an interval of 1 month.

Results:

Regular follow-up done for 1 year. At the end of all the four injections, the lesion healed completely with a relief in presenting symptoms. No complications were reported. At 3 months post-therapy, the patient was able to walk without pain. After 1 year of follow-up, the patient was symptom-free with no signs of recurrence.

Conclusion:

Surgical resection/curettage has higher chances of recurrence; therefore, usage of intralesional sclerotherapy agent polidocanol should be considered the treatment of choice in the lesions smaller than 5 cm.

Synchronous rectal prolapse and midgut volvulus presenting as complete small bowel gangrene

&lt;b&gt;Introduction:&lt;/b&gt; Adult midgut malrotation is very rare. The presentation in adults is mostly subtle; the diagnosis is often made on imaging. &lt;br&gt;&lt;b&gt;Case report:&lt;/b&gt; A 32-year-old man presented with a 3-day history of an irreducible painful mass protruding per rectum, followed by abdominal pain and constipation. The patient was febrile and toxic, with marked signs of peritonitis and complete fullthickness irreducible rectal prolapse. Abdominal radiographs showed multiple air-fluid levels. A diagnosis of irreducible rectal prolapse with intestinal obstruction was made. Laparotomy revealed complete small bowel gangrene, abnormal rotation of the small bowel 180° around the mesenteric root, hypermobile duodenojejunal flexure and ileocaecal junction and an abnormally mobile caecum lying in the central abdomen. Abnormal mobility of the sigmoid colon with a large mesocolon, and a large irreducible rectosigmoid intussusception, was also noted. Our patient is probably the first case in literature, which may prompt awareness of simultaneously-occurring disorders of fixation, and preventive steps.

Assessing the Impact of Inflammatory Markers and CT Severity Score on Disease Severity of COVID-19 Patients Admitted to ICU at a Tertiary Hospital

BACKGROUND

In December 2019, SARS-COV-2 infection emerged in Wuhan, China causing COVID-19 and subsequently spread throughout the globe. A great uncertainty is associated with the disease progression, as the risk of severe COVID-19 is not uniform among all the patients. Systemic inflammation has been reported as a predictor for COVID-19 outcomes. Elevated levels of inflammatory markers are shown to be associated with endothelial dysfunction, cytokine storm and coagulopathy in COVID-19. There is a growing body of evidence, that these findings exert influence in the causation of mortality in patients with severe Covid-19. The present study is carried out with an aim to evaluate the clinical outcomes of patients by interrelating their clinical severity with inflammatory markers and CT (Computed tomography) severity score (CTSS).

OBJECTIVES

The aim of the study is to correlate COVID-19 severity with inflammatory markers and CT severity score. We also aim to determine the optimal cut-off values for inflammatory markers and CT severity scores in order to establish their interrelationship to the disease severity.

MATERIALS AND METHODS

It is a hospital-based retrospective observational study. The study was conducted over a period of four months (July 2020 to October 2020) based on data obtained from the records of patients, admitted with a laboratory confirmed SARS-COV-2 infection. The current study included a total of 84 patients, admitted to ICU with the severe COVID-19.Study tools included serum CRP, serum ferritin, D-dimer, neutrophil-to-lymphocyte ratio (NLR), interleukin-6 (IL-6) and 25-point CT severity score obtained from HRCT (high resolution computerized tomography) chest.

RESULTS

Out of 84 patients recruited, 54 patients were survivors and 30 patients were non-survivors (deceased). 78% of the study population was male and 22% was female. For survivors, average CTSS was 12.43 ± 5.7 and whereas average CTSS for non-survivors was 18.87 ± 4.68(p&lt;0001). Average D-dimer was 2.5 ± 1.43 in the survivor group and 3.39 ± 0.95 for non-survivors (p&lt;0.004). Correlation coefficient of CTSS with FiO2 is 0.685 (p&lt;0.0001). The optimal cut-off value for predicting mortality for D-dimer is &gt;2.4 (p&lt;0.0012) and for CTSS is &gt;15 (p&lt;0.0001).

CONCLUSION

The disease severity was significantly correlated with CTSS and D- dimer. Severe COVID-19 was also associated with a high NLR (neutrophil to lymphocyte ratio) and moderately elevated inflammatory markers (CRP, Ferritin, IL-6). CTSS &gt;15 and D-dimer &gt;2.4 correlate strongly with mortality. CTSS has the greatest diagnostic accuracy for stratifying the disease severity and predicting the mortality among the markers/ characteristics compared.
