Health-related quality of life of salvage prostate reirradiation using stereotactic ablative radiotherapy with urethral-sparing.

PurposeTo explore whether prostate motion mitigation using the rectal distension-mediated technique is safe and effective in stereotactic ablative radiation therapy (SABR) salvage treatment of intraprostatic cancer recurrences following initial radiotherapy for primary prostate cancer.Materials and methodsBetween July 2013 and December 2020, 30 patients received salvage SABR for 68Ga- PSMA-11 PET/CT-detected intra-prostatic relapses. Median time from primary RT to salvage reirradiation was 70.2 (IQR, 51.3-116.0) months. Median PSA at retreatment was 3.6 ng/mL (IQR, 1.9-6.2). Rectal distension-mediated SABR was achieved with a 150-cm3 air-inflated endorectal balloon and a Foley catheter loaded with 3 beacon transponders was used for urethra visualization and on-line tracking. MRI-based planning employed a 2-mm expansion around the planned target volume (PTV), reduced to 0-mm at the interface with critical organs at risk (OARs). Volumetric Modulated Arc Therapy (VMAT) permitted a 20% dose reduction of the urethra. VMAT simultaneous integrated boost (SIB) of the dominant intraprostatic lesion was deployed when indicated. Median SABR dose was 35 Gy (7 Gy per fraction over 5 consecutive days; range 35-40 Gy). Toxicity assessment used CTCAE v.4 criteria.ResultsMedian follow-up was 44 months (IQR, 18-60). The actuarial 3- and 4-year biochemical relapse free survival was 53.4% and 47.5%, respectively. Intraprostatic post-salvage relapse by PSMA PET/CT was 53.3%. Acute grade 2 and 3 genitourinary (GU) toxicities were 20% and 0%, respectively. There were no instances of acute grade ≥2 rectal (GI) toxicity. Late grade 2 and 3 GU toxicities occurred in 13.3% and 0% of patients, respectively. There were no instances of grade ≥2 late rectal toxicity. Patient-reported QOL measures showed an acute transient deterioration in the urinary domain 1 month after treatment but returned to baseline values at 3 months. The median IPSS scores rose over baseline (≥5 points in 53% of patients) between month 6 and 12 post-treatment as a result of urinary symptoms flare, eventually receding at 18 months. The bowel domain metrics had no appreciable changes over time.ConclusionPursuit of local control in intraprostatic failures is feasible and can be achieved with an acceptably low toxicity profile associated with effective OAR sparing.

Background and purposeIntracerebral haemorrhage volume (ICHV) is prognostically important but does not account for intracranial volume (ICV) and cerebral parenchymal volume (CPV). We assessed measures of intracranial compartments in acute...

FROM ALL LUNG TO ALL AIR: A CASE OF IATROGENIC FUNCTIONAL PNEUMONECTOMY

FROM ALL LUNG TO ALL AIR: A CASE OF IATROGENIC FUNCTIONAL PNEUMONECTOMY

BILATERAL CHRONIC SUBDURAL HEMATOMA – CLINICAL PRESENTATION, RISK FACTORS, MANAGEMENT AND OUTCOME: A SINGLE CENTRE EXPERIENCE FROM NORTH-EASTERN INDIA

Study design: Background: Retrospective hospital-based study. Annual incidence of bilateral Chronic Subdural Hematoma (CSDH) is increasing due to an increase in the aging population, associated medical comorbidities such as hemodialysis, anticoagulant and/or antiplatelet therapy. 1. To study the clinical spectrum of Bilateral Chronic Subdural Hematoma Objectives: patients. 2. To study the treatment modalities used and outcome of the patients. A retrospective hospital-based study was carried Method: out on 50 conrmed patients of bilateral CSDH. Information of patients such as socio-demographic prole, clinical presentation, and laboratory investigations, along with treatment and outcome were recorded and analyzed. Among 50 patients, male and female were 80% and 20% res Results: pectively. The mean age of patients was 62.08 years. A history of head injury was reported by 40% of patients. The mean Glasgow coma scale (GCS) was 12.24. Common presenting symptoms were headache (76%), hemiparesis (40%), aphasia (28%), complete loss of consciousness (20%). Clinical improvement was observed in 80% while 10% had no change, 04% showed clinical deterioration and 06% of patients died during treatment. Bilateral CSDH is common Conclusion: in the elderly and prognosis is poor with increasing age. Bilateral hematoma has a higher risk of acute deterioration of clinical symptoms because of downward herniation, resulting in a poor clinical outcome. Timely interventions can improve the outcome in bilateral CSDH patients.

Outcomes of patients with acute respiratory failure on veno-venous extracorporeal membrane oxygenation requiring additional circulatory support by veno-venoarterial extracorporeal membrane oxygenation.

ObjectiveVeno-venous (V-V) extracorporeal membrane oxygenation (ECMO) is increasingly used to support patients with severe acute respiratory distress syndrome (ARDS). In case of additional cardio-circulatory failure, some experienced centers upgrade the V-V ECMO with an additional arterial return cannula (termed V-VA ECMO). Here we analyzed short- and long-term outcome together with potential predictors of mortality.DesignMulticenter, retrospective analysis between January 2008 and September 2021.SettingThree tertiary care ECMO centers in Germany (Hannover, Bonn) and Switzerland (Zurich).PatientsSeventy-three V-V ECMO patients with ARDS and additional acute cardio-circulatory deterioration required an upgrade to V-VA ECMO were included in this study.Measurements and main resultsFifty-three patients required an upgrade from V-V to V-VA and 20 patients were directly triple cannulated. Median (Interquartile Range) age was 49 (28–57) years and SOFA score was 14 (12–17) at V-VA ECMO upgrade. Vasoactive-inotropic score decreased from 53 (12–123) at V-VA ECMO upgrade to 9 (3–37) after 24 h of V-VA ECMO support. Weaning from V-VA and V-V ECMO was successful in 47 (64%) and 40 (55%) patients, respectively. Duration of ECMO support was 12 (6–22) days and ICU length of stay was 32 (16–46) days. Overall ICU mortality was 48% and hospital mortality 51%. Two additional patients died after hospital discharge while the remaining patients survived up to two years (with six patients being lost to follow-up). The vast majority of patients was free from higher degree persistent organ dysfunction at follow-up. A SOFA score > 14 and higher lactate concentrations at the day of V-VA upgrade were independent predictors of mortality in the multivariate regression analysis.ConclusionIn this analysis, the use of V-VA ECMO in patients with ARDS and concomitant cardiocirculatory failure was associated with a hospital survival of about 50%, and most of these patients survived up to 2 years. A SOFA score > 14 and elevated lactate levels at the day of V-VA upgrade predict unfavorable outcome.

Determinants of visual and endocrinological outcome after early endoscopic endonasal surgery for pituitary apoplexy.

Patients diagnosed with pituitary apoplexy and presenting with acute visual deterioration require urgent surgical resection. This is also commonly associated with pituitary hypopituitarism that requires hormonal replacement for correction. This study was undertaken to evaluate the clinical recovery of 45 patients diagnosed with symptomatic pituitary apoplexy who underwent early (within 72 h of symptom onset) endoscopic transsphenoidal surgical resection with an emphasis on visual, ocular craniopathy, and endocrinological outcome. This is a retrospective analysis of a consecutive series of patients diagnosed with pituitary apoplexy between 2011 and 2020 treated by early (within 72 h of symptom onset) endoscopic transsphenoidal surgical resection. All tumors were histologically proven as pituitary adenomas. Clinical and neuro-ophthalmological examinations, imaging studies, and endocrinological evaluation were retrospectively reviewed. Patients with a minimum of 6 months follow-up were included in the study. The influence of patients' demographics, extent of visual and ocular motility impairment, preoperative endocrinological dysfunction, tumor size and extent, degree of resection, and surgical complications were analyzed as potential prognostic factors for recovery. Forty-five patients were included in this retrospective study. Ages ranged from 27 to 57 years (mean: 42 years). All patients presented with headache and variable degrees of visual loss and visual field deficit. Ophthalmoplegia was present in 22 (48.9%) patients with 17 (37.8%) having bilateral ocular cranial nerve palsy. All patients had variable degrees of endocrinological deficiencies. All patients showed evidence of low cortisol, 14 (31.1%) showed hypothyroidism and 11 (24.4%) showed hypogonadism. There was evidence of hyperprolactinemia in 16 (35.6%) patients. All patients harbored a pituitary macroadenoma. Tumor resection was complete in 33 (73%) of patients, with residual tumor related to cavernous sinus or retrosellar extension. Operative complications were mainly related to short-term nasal complications occurring in 14 (31%) patients. Cerebrospinal fluid leak requiring revision surgery occurred in only one patient harboring a modified SIPAP Grade 3s tumor. Transient diabetes insipidus occurred in 9 (20%) patients, with 2 (4.4%) requiring long-term hormonal replacement. The mean follow-up was 25 months. Baseline visual improvement was achieved in 39 (86.7%) patients. Ocular cranial nerve palsy showed complete recovery in 17 (77.2%) patients. Endocrine follow-up showed that patients with panhypopituitarism (11 [24.4%]) failed to recover. The current surgical series showed safety in terms of low complication rate and efficacy in terms of clinical outcome. The significant prognostic factor related to visual recovery was the degree of preoperative visual deficit. Recovery of ocular cranial neuropathy showed a higher recovery rate when it was unilateral as opposed to bilateral. Pituitary hormonal recovery was less favorable with pituitary panhypopituitarism being a poor prognostic factor.

Subacute Cardiac Tamponade in a COVID-19 Patient Despite Negative Testing

COVID-19 infection has been documented to cause a wide range of symptoms including cardiac complications. We present a case of subacute cardiac tamponade in a patient infected with COVID-19 in the absence of respiratory symptoms; we also review the current literature on this rare sequela. Our patient is a 67-year-old man who presented to the hospital due to intermittent chest pain for three weeks. COVID-19 polymerase chain reaction (PCR) testing was negative two times. He had an outpatient echocardiogram that showed a moderate pericardial effusion about a week prior to the hospital presentation. On admission, a repeat echocardiogram showed a large pericardial effusion with tamponade physiology. Pericardiocentesis did not reveal a clear etiology of the hemorrhagic effusion but four days later, the patient was found to be positive for COVID-19 infection without any clear respiratory illness. Given the absence of other etiology and negative workup, cardiac tamponade was attributed to pericardial inflammation from this virus and our patient improved with colchicine and steroids. We, therefore, advise providers to consider COVID-19 as a cause of hemorrhagic, cryptogenic cardiac tamponade despite negative COVID-19 testing. We also review 42 additional reported cases of cardiac tamponade in patients infected with COVID-19. COVID-19 can cause cardiac tamponade even in the absence of pulmonary disease. This case and literature review highlight tamponade as a rare complication of COVID-19 and should be considered in the differential of any acute deterioration in this patient population.

Detecting Acute Deterioration in Older Adults Living in Residential Aged Care: A Scoping Review.

To explore models, processes, or tools implemented in residential aged care (RAC) to support registered nurses (RNs) to identify and respond to the acute deterioration of residents. Scoping literature review of English Language articles published in peer reviewed journals. Studies were conducted in RAC facilities providing long-term 24-hour medical, nursing, and social care for people age 65years or older with age-related disability. We completed a MESH term and key word search of MEDLINE, Embase, CINAHL, PubMed, and Google Scholar. Included studies had (1) part of the intervention based in RAC; (2) had a direct impact on RAC day to day practice; and (3) contained or provided access to the detail of the intervention. Data was charted by author, date, country, study design and the components, genesis, and efficacy of the methods used to identify and respond to acute deterioration. We found 46 studies detailing models of care, clinical patterns of acute deterioration, and deterioration detection tools. It was not possible to determine which element of the models care had the greatest impact on RN decision making. The clinical patterns of acute deterioration painted a picture of acute deterioration in the frail. There was limited evidence to support the use of existing deterioration detection tools in the RAC population. We found no straight forward systematic method to support RAC RNs to identify and respond to the acute deterioration of residents. This is an important practice gap. The clinical pattern of acute deterioration described in the literature has the potential to be used for the development of a tool to support RAC RNs to identify and respond to the acute deterioration of residents.

A Review on Treatment of Perforated Peptic Ulcer by Minimally Invasive Techniques.

Peptic ulcers are caused by acid peptic damage to the mucosal layer in the gastro-duodenal area of the gut, which results in mucosal erosion that exposes the underlying tissues to the digestive action of gastro-duodenal secretions. This pathology was traditionally related to a hypersecretory acid environment, dietary factors and stress. There are other causes of ulcers such as Helicobacter pylori infection, excessive use of NSAIDs, and smoke and alcohol abuse. Perforation and bleeding are two major complications of the disease. A typical symptom of perforated peptic ulcers (PPU) is a sudden onset of abdominal pain or acute deterioration of the ongoing abdominal pain. Perforated peptic ulcer can be diagnosed by a simple X-ray and CT scan of the abdomen. Laboratory tests are also run to rule out differential diagnosis. Although there are several choices for surgical intervention, minimally invasive techniques have been taking over as a frequent option in feasible cases. Techniques like laparoscopy have been surfacing because of their advantages. But the efficiency of minimally invasive techniques compared to conventional approach is yet to be defined. Hence, the present review of the literature aims to describe and delineate the current perspective on PPU management by minimally invasive and low risk techniques.

Optical coherence tomography in the differential diagnostics of important neuro-ophthalmological disease patterns

There are many disease patterns that are treated jointly by neurologists and ophthalmologists, for which optical coherence tomography (OCT) is of important differential diagnostic significance. In this context neurologists are mainly confronted by two patient collectives: patients with an acute ischemic event, who present with an acute but painless monocular visual deterioration (for central retinal artery occlusion) or with a monocular visual field defect (for arterial branch occlusion or anterior ischemic optic neuropathy). The second collective is patients without ophthalmological symptoms but with conspicuous optic nerve findings (papilledema or optic disc drusen). In this overview article both patient collectives are considered separately. In addition, the most important OCT findings for optic neuritis are presented. Before the disease patterns are described in detail, the normal OCT findings and the diagnostic possibilities of OCT are explained.

Infiltrative multifocal glioblastoma progression in a twelve-year-old boy after COVID-19 infection: a case report

Background: Glioblastoma is one of the most malignant types of primary central nervous system tumors with a high recurrence rate and dismal prognosis. Multifocal glioblastoma has been shown to have a poorer prognosis than solitary glioblastoma. Cancer patients are at risk of contracting COVID-19. It is hypothesized that COVID-19 may induce glioma tumorigenesis via angiotensin enzyme 2 receptor. We reported a rare pediatric multifocal glioblastoma in a twelve-year-old boy complicated with COVID-19. Case Presentation: The patient was a twelve-year-old boy with a new-onset unprovoked seizure and headache. Magnetic resonance imaging (MRI) showed a heterogeneous solid cystic mass in the left temporal region (2.1x2.1x2.8 cm) with an increased choline/creatinine ratio and choline/n-acetyl acetate aspartate (NAA) ratio suggestive for high-grade glioma. The patient was contracting COVID-19 shortly after the diagnosis of glioblastoma. Two weeks later, patients came with significant neurological deterioration, hemiparesis, headache, and vomiting. MRI showed an infiltrative mass in the temporal and parietal region (5.05x8.03x8.3 cm) with intratumoral hemorrhage, also causing midline shift deviation (11.9 mm). The patient underwent trepanation and total safe resection of the tumor. Histopathological findings showed neoplastic cells with abundant mitotic figures, necrotic foci and pseudopalisading necrosis. These findings confirmed the diagnosis of multifocal glioblastoma. Conclusion: Glioblastoma is a rare disease in the pediatric population with a poor prognosis due to its infiltrative nature and high recurrence rate. The patient had an acute deterioration of the neurological condition and rapid growth of the tumor after he contracted COVID-19, which may or may not be incidental. Further observation of similar cases will be required to determine the association between glioblastoma and COVID-19.

894 What Proportion of Acute Admissions for Urinary Tract Infection Under Urology Require Surgical Intervention Within 6 Months?

Abstract Introduction All male patients with urinary tract infections (UTI) at this large district general hospital are admitted under the care of the urology department. This audit aims to establish how many male patients over the age of 70 with a diagnosis of UTI required surgical intervention in the 6 months following admission. Method We performed a retrospective audit of all patients over 70 admitted with a UTI over a five-month period. Patients with recent instrumentation or other pathologies, including visible haematuria or ureteric stones confirmed on imaging in the accident and emergency department were excluded. Results Of the 30 patients included, five (16.7%) required invasive intervention. Three (10%) acutely, (two ureteric stents, one nephrostomy), two (6%) as an outpatient on an elective basis (flexible ureteroscopy and prostate artery embolisation). Conclusions Over 80% of patients included in this audit did not require surgical intervention within six months. Whilst UTI is a significant finding in younger men suggestive of structural or systemic abnormality, UTIs in incontinent, catheterised, or older men does not carry the same risks and rarely requires intervention. Elderly care wards were established to ensure older patients receive support to improve health functioning and prevent acute deterioration in physical and mental health during admission. Given that less than 20% of men required intervention, this cohort of patients would be better admitted to wards geared towards elderly care who are better able to manage their co-morbidities and have the resources for early physiotherapy and occupational therapy input.

Comprehensive Analysis of Fibroblast Activation Protein Expression in Interstitial Lung Diseases.

Rationale: Sustained activation of lung fibroblasts and the resulting oversynthesis of the extracellular matrix are detrimental events for patients with interstitial lung diseases (ILDs). Lung biopsy is a primary evaluation technique for the fibrotic status of ILDs, and is also a major risk factor for triggering acute deterioration. Fibroblast activation protein (FAP) is a long-known surface biomarker of activated fibroblasts, but its expression pattern and diagnostic implications in ILDs are poorly defined. Objectives: The present study aims to comprehensively investigate whether the expression intensity of FAP could be used as a potential readout to estimate or measure the amounts of activated fibroblasts in ILD lungs quantitatively. Methods: FAP expression in human primary lung fibroblasts as well as in clinical lung specimens was first tested using multiple experimental methods, including real-time quantitative PCR (qPCR), Western blot, immunofluorescence staining, deep learning measurement of whole slide immunohistochemistry, as well as single-cell sequencing. In addition, FAP-targeted positron emission tomography/computed tomography imaging PET/CT was applied to various types of patients with ILD, and the correlation between the uptake of FAP tracer and pulmonary function parameters was analyzed. Measurements and Main Results: Here, it was revealed, for the first time, FAP expression was upregulated significantly in the early phase of lung fibroblast activation event in response to a low dose of profibrotic cytokine. Single-cell sequencing data further indicate that nearly all FAP-positive cells in ILD lungs were collagen-producing fibroblasts. Immunohistochemical analysis validated that FAP expression level was closely correlated with the abundance of fibroblastic foci on human lung biopsy sections from patients with ILDs. We found that the total standard uptake value (SUV) of FAP inhibitor (FAPI) PET (SUVtotal) was significantly related to lung function decline in patients with ILD. Conclusions: Our results strongly support that invitro and invivo detection of FAP can assess the profibrotic activity of ILDs, which may aid in early diagnosis and the selection of an appropriate therapeutic window.

Angled Ultrasonic Bone Curette-Assisted Circumferential Decompression for Thoracic Myelopathy Caused by Severely Anterior Ossification.

ObjectiveThoracic myelopathy caused by severe anterior ossification is often progressive and fails to respond to conservative treatment. Removal of the compressing ossification is the most effective method but is hard to operate. In this study, we describe a novel one‐stage posterior circumferential decompressive procedure assisted by an angled ultrasonic bone curette (UBC) for thoracic myelopathy caused by severe anterior ossification and evaluate its safety and efficacy.MethodsThe current study enrolled 15 consecutive patients (five men and 10 women) with thoracic myelopathy caused by severely anterior ossification between January 2017 and December 2019. All patients underwent posterior circumferential decompression assisted by angled UBC and segmental instrumentation with interbody fusion. At the time of surgery, the average age was 58.6 ± 6.3 years (47–70 years). Before and after surgery, the patient data, clinical manifestation, operative levels, blood loss, operative time, perioperative complications, Japanese Orthopaedic Association (JOA) score were recorded and analyzed retrospectively.ResultsAll patients had successful one‐stage posterior circumferential decompression to remove anterior ossifications directly. There were 12 cases of OPLL, two cases of a calcified giant herniated disc, and one case of osteophyte. The average operation time was 153.4 ± 53.4 min (77–242 min), with a mean blood loss of 463.5 ± 155.8 mL (240–780 mL). The average length of stay in the hospital was 14.3 ± 4.7 days (9–25 days) and the mean follow‐up duration was 20.8 ± 8.8 months (12–39 months). Almost all patients had subjective improvement in motor power and gait. The average preoperative JOA score was 4.5 ± 1.6, which improved to 9.0 ± 1.8 at the final follow‐up. Postoperative differences in the overall JOA scores showed significant improvement (F = 105.446, p < 0.01). The overall recovery rate at the final examination scored 70.9% ± 25.0%. According to Hirabayashi's classification, eight cases were rated as excellent, four as good, two as fair, and one as unchanged. No patient was graded as deteriorated. Two patients (13.3%) experienced intraoperative cerebrospinal fluid leakage, while two cases (13.3%) experienced unilateral intercostal neuralgia, and only one (6.7%) encountered acute neurological deterioration. All these patients were treated conservatively and their neurological function improved significantly. At the follow‐up, there was no evidence of neurological deterioration.ConclusionCircumferential decompression assisted by angled UBC can preserve more posterior elements of the involved levels, maintaining an intact pleura and reducing the operation time and blood loss for thoracic myelopathy caused by severe anterior ossification. It is a safe, effective, and technically feasible method to provide surgeons with a new option for thoracic spinal circumferential decompression.

Metformin toxicity: A meta-summary of case reports.

BACKGROUNDMetformin is arguably the most commonly prescribed oral hypoglycemic agent for the management of diabetes. Due to the lack of randomized control trials, most of the data pertaining to the clinical course, therapeutic interventions and outcomes of patients with metformin induced toxicity has come from case reports or series. AIMTo analyse the symptomology, clinical interventions and outcomes of patients presenting with severe metformin toxicity by reviewing the published case reports and series.METHODSWe performed a systematic search from PubMed, Science Direct, Reference Citation Analysis (https://www.referencecitationanalysis.com/) and Google Scholar databases using the terms “metformin” AND “toxicity” OR “overdose” OR “lactic acidosis” OR “hyperlactatemia”. The inclusion criteria were: (1) Case reports or case series with individual patient details; and (2) Reported toxicity or overdose of metformin in adults, published in the English language. Data regarding baseline demographics, clinical presentation, therapeutic interventions, intensive care unit course and overall outcome were collected. RESULTSTwo hundred forty-two individual cases were analysed, from 158 case reports and 26 case series, with a cumulative mortality of 19.8%. 214 (88.4%) patients were diabetics on metformin. 57 (23.6%) had acute ingestion, but a great majority (76.4%) were on metformin in therapeutic doses when they developed toxicity. Metformin associated lactic acidosis (MALA) was the most commonly reported adverse effect present in 224 (92.6%) patients. Most of the patients presented with gastrointestinal and neurological symptoms and a significant number of patients had severe metabolic acidosis and hyperlactatemia. The organ support used was renal replacement therapy (RRT) (68.6%), vaso-pressors (58.7%) and invasive mechanical ventilation (52.9%). A majority of patients (68.6%) received RRT for toxin removal, renal dysfunction and correction of MALA. Patients with lowest pH and highest serum lactate and metformin levels also had favourable outcomes with use of RRT.CONCLUSIONMost of the reported cases were on therapeutic doses of metformin but developed toxicity after an acute deterioration in renal functions. These patients may develop severe lactic acidosis, leading to significant morbidity and need for organ support. Despite severe MALA and the need for multiple organ support, they may have good outcomes, especially when RRT is used. The dose of metformin, serum pH, lactate and metformin levels may indicate the severity of toxicity and the need for aggressive therapeutic measures but may not necessarily indicate poor outcomes.

THE PREVALENCE OF BACTERIA OF THE GENUS PROTEUS SPP. IN DIFFERENT TYPES OF RESEARCH FOOD PRODUCTS

This article discusses the issue of contamination of food products by microorganisms of the genus Proteus, which actively multiply on a protein nutrient medium, causing the rotting of meat, fish, and other protein-rich foods. It is noted that recently in catering facilities there are often cases of toxic infections caused by the presence of these particular bacteria. The article draws attention to the fact that acute enteroidea, occurring as gastroenteritis, gastritis, or colienteritis, among young children, especially those with reduced immunity, is more severe, accompanied by symptoms of toxicosis, sometimes leading to complications up to hemolytic thrombopenia, anemia, acute renal impairment, etc. The article presents statistical materials obtained in the course of forensic research carried out in the Food Products and Drinks Expertise Department, which allow us to summarize the importance of strengthening control over the conduct of general sanitary measures and preventive measures in public catering facilities, in particular children’s institutions and hospitals. Key words: Proteus spp., pathogenicity, food poisoning, food products expertise, meat products.

An approach to acute clinical deterioration in patients with late-stage Parkinson's disease.

Idiopathic Parkinson's disease is a slowly progressive neurodegenerative disease. In the absence of disease-modifying therapies, patients inevitably progress to late-stage disease, characterised by a shift towards increasing disability from predominantly non-motor symptoms, which may be poorly levodopa responsive. The aim of this article is to provide generalpractitioners (GPs) with a practicalapproach to the diagnosis and management of acute clinical deterioration in patients with late-stage Parkinson's disease. The authors outline common causes for such change and an approach to their workup and management. With an ageing population, we are seeing an increased prevalence of Parkinson's disease at all stages. Neurologists, geriatricians and GPs alike should therefore be familiar with the syndrome of late-stage Parkinson's disease and be equipped with treatment strategies to address acute non-motor and motor deteriorations.

Cerebral abscess as a neurosurgical emergency in Eisenmenger syndrome: illustrative case.

Eisenmenger syndrome caused by severe pulmonary arterial hypertension in congenital heart disease can cause multisystemic involvement and is a risk factor for development of cerebral abscess. Cerebral abscess, if not detected and treated in a timely manner, can present as acute neurosurgical emergency. The authors reported a case of cerebral abscess in a patient with Eisenmenger syndrome. The patient presented with acute neurological deterioration with mass effect and cerebral infarcts and received emergency neurosurgical intervention. A further literature search was done to identify prior reported cases of cerebral abscess with Eisenmenger syndrome. Patients with Eisenmenger syndrome have compromised cardiorespiratory status, and decision for neurosurgical intervention should be given careful consideration. Multidisciplinary team management along with preoperative optimization of the patient should be used.

Chile

After an impressive recovery from the fallout of the Covid-19 pandemic, the Chilean economy is confronting an acute deterioration of the external environment. Downside risks have materialized, including a tightening of global financial conditions, a slowdown in global growth, and a substantial drop in Chile’s terms of trade. Domestic economic policies are appropriately being recalibrated to mitigate risks and preserve macroeconomic stability, while supporting vulnerable groups. The authorities will continue leveraging on Chile’s very strong fundamentals and policy frameworks to implement an ambitious reform agenda in a challenging external environment.

Air leaks in COVID-19.

Coronavirus disease 2019 (COVID-19) continues to create havoc and may present with myriad complications involving many organ systems. However, the respiratory system bears the maximum brunt of the disease and continues to be most commonly affected. There is a high incidence of air leaks in patients with COVID-19, leading to acute worsening of clinical condition. The air leaks may develop independently of the severity of disease or positive pressure ventilation and even in the absence of any traditional risk factors like smoking and un-derlying lung disease. The exact pathophysiology of air leaks with COVID-19 remains unclear, but multiple factors may play a role in their development. A significant proportion of air leaks may be asymptomatic; hence, a high index of suspicion should be exercised for enabling early diagnosis to prevent further deterioration as it is associated with high morbidity and mortality. These air leaks may even develop weeks to months after the disease onset, leading to acute deterioration in the post-COVID period. Conservative management with close monitoring may suffice for many patients but most of the patients with pneumothorax may require intercostal drainage with only a few requiring surgical interventions for persistent air leaks.
