The increasing prevalence of substance misuse in modern culture is contributing to the growth in neonatal abstinence syndrome (NAS) cases in India. NAS can be challenging to diagnose due to nonspecific symptoms and maternal suppression of drug history. Only a few reports of NAS have been published from India. This is a case series of three newborns from India who all had symptoms like restlessness, high-pitched crying, excessive sweating, vigorous sucking, tremors, and diarrhea. The investigations did not lead to any conclusions. In the first case, the mother was treated with a combination of psychotropic medications, including selective serotonin reuptake inhibitors (SSRIs), atypical antipsychotics, and tricyclic antidepressants. In the second case, the mother was a nicotine addict, while in the third case, the mother had an opiate addiction. It was only after being asked several times that the abuse background of the last two cases was revealed. As a result, three cases of NAS were diagnosed, successfully managed with phenobarbitone, and discharged.

UNASSIGNED: Chronic ketamine use can lead to sphincter of oddi dysfunction (SOD), causing various hepatobiliary complications. Recognizing substance abuse history is vital for early detection. Timely intervention can prevent irreversible liver and pancreas damage.
UNASSIGNED: Ketamine is commonly abused as a recreational drug worldwide due to its ability to induce euphoria-like effects. Ketamine abuse is associated with many hepatobiliary side effects ranging from cholestasis to biliary sepsis and death. Here we present a case of a young 29-year female with upper abdominal pain due to SOD resulting from chronic use of ketamine. SOD can result in obstruction or dysfunction of the bile and pancreatic ducts. Ketamine induces SOD by activation of the muscarinic receptors in the sphincter of oddi. Detail history of substance abuse is crucial for early identification of ketamine-induced SOD. Early identification and treatment of this rare condition can prevent permanent injury to the liver and pancreas.

UNASSIGNED: Coronary arteriovenous fistulas present an abnormal connection between the coronary arteries and an adjacent systemic or pulmonary vessel. They are rare, representing 0.002% of the general population. The majority is congenital but may additionally occur related to trauma or interventional cardiac procedures.
UNASSIGNED: We present the case of a 48-year-old male with a history of untreated bacterial endocarditis developing a right coronary/superior vena cava fistula. We detail the imaging findings of this rare phenomenon to arrive at this diagnosis. We describe his clinical course and the interventions considered, including surgical extraction. Unfortunately, this patient left against medical advice before completing recommended treatment.
UNASSIGNED: We present the first documentation of a right coronary/superior vena cava fistula secondary to chronic untreated bacterial endocarditis. Clinicians should be aware of this rare complication.

Etomidate is a nonbarbiturate sedative derived from imidazole. Prolonged and excessive use of etomidate can lead to the suppression of adrenocortical function, myoclonus, and even death. This report describes a rare case of a 47-year-old man who died from acute intoxication after oral ingestion of liquid containing etomidate. The cause of death was conclusively attributed to etomidate based on a comprehensive investigation, including autopsy, histopathological examination, toxicological analysis, and biochemical analysis. This is the first reported case of a fatality solely resulting from the oral ingestion of etomidate, which can provide valuable insights for future forensic investigations involving etomidate poisoning. Therefore, it is imperative to share this case with the scientific community.

As a GABA-β receptor agonist, the central muscle relaxant Baclofen (BAC) has a potential of abuse. Unfortunately, the sense of wellbeing and pleasure is obtained at very high BAC doses. This is associated with many life-threating or even fatal cases due to neurological and respiratory failures. Moreover, having narrow therapeutic index makes BAC a high-risk drug. This is potentiated in case of long-treatment regimen or off-label use in smoking and alcohol cessation protocols. Until now, there is no rapid diagnostic test available for BAC screening. Therefore; It is quite difficult to routinely monitor cases on BAC regimen. On the other hand, smartphone-based colorimetric point of care testing (POCT) is displacing conventional analytical approaches in the detection and assay of abused drugs as well as therapeutic drug monitoring. It offers on-site, rapid, easy, affordable and interpretable analysis. Incorporating smartphone as a portable device facilitates its application, especially in remote areas and low-income countries. For the first time, the current work presents a smartphone-based colorimetric POCT for BAC analysis in urine without interference from urine matrix. It depends on BAC reaction with naphthoquinone sulfonate (NQS) in highly alkaline aqueous medium. The developed color was captured in a customized photo box using smartphone camera. Then, intensity of the blue channel was measured by a software application \"Color Analyzer\". All parameters were optimized with respect to the colorimetric reaction, photographing and smartphone-based analysis. All parameters were successfully investigated according to FDA guidelines for bioanalytical method validation. Also, all POCT criteria were considered as per WHO requirements. This method could determine BAC, linearly, from 0.02 to 0.21 mmol L-1 in urine. Moreover, LLOQ was lower than the expected BAC therapeutic concentrations in urine. The proposed method proved high reliability and suitability to analyze BAC in urine. This strongly recommends its routine application in screening BAC abusers and BAC therapeutic monitoring.

Opioid deaths have increased in England and Wales. Coroners\' Prevention of Future Deaths reports (PFDs) provide important insights that may enable safer use and avert harms, yet reports implicating opioids have not been synthesized. We aimed to identify opioid-related PFDs and explore coroners\' concerns to prevent future deaths.
In this systematic case series, we screened 3897 coronial PFDs dated between 01 July 2013 and 23 February 2022, obtained by web scraping the UK\'s Courts and Tribunals Judiciary website. PFDs were included when an opioid was implicated in the death. Included PFDs were descriptively analysed, and content analysis was used to assess concerns reported by coroners.
Opioids were involved in 219 deaths reported in PFDs (5·6% of PFDs), equating to 4418 years of life lost (median 33 years/person). Morphine (29%), methadone (23%) and diamorphine (16%) were the most common implicated opioids. Coroners most frequently raised concerns regarding systems and protocols (52%) or safety issues (15%). These concerns were most often addressed to National Health Service (NHS) organizations (51%), but response rates were low overall (47%).
Opioids could be used more safely if coroners\' concerns in PFDs were addressed by national organizations such as NHS bodies, government agencies and policymakers, as well as individual prescribing clinicians.

We report a case of a 32-year-old male with a history of type 1 diabetes, inhaled drug use, and alcohol use disorder, who presented with encephalopathy, holocranial headaches, neck pain, confusion, and generalized tonic-clonic seizures. The patient initially presented at a rural community hospital with a fever and was found to be in diabetic ketoacidosis (DKA). He was also hemodynamically stable but stuporous, prompting intubation to protect his airway. Despite initial treatment measures, his neurological condition worsened and he remained ventilator-dependent. Key findings include a high glucose level, presence of ketones, and evidence of drug use. Blood cultures showed no growth, but his febrile state persisted. Cerebrospinal fluid (CSF) analysis revealed mild pleocytosis, hyperglycorrhachia but normal protein, with no growth. Neuroimaging showed right hemispheric slowing on EEG and diffusion restriction in the right frontal lobe on MRI. The patient\'s neurological status worsened on the second day of admission, manifesting as sluggish pupillary reflexes, right third nerve palsy, and decerebrate posturing. Emergent MRI suggested cerebral edema, leading to initiation of hypertonic saline. This case highlights the diagnostic challenges and critical management considerations in a patient with multiple comorbidities presenting with unexplained neurological deterioration, emphasizing the importance of a comprehensive and timely approach to diagnosis and treatment.

Serratia marcescens is a gram-negative bacillus that is an opportunistic agent in respiratory tract infections, urinary tract infections, and septicemia. It is rarely also a cause of infective endocarditis which follows a rapid and devastating course, typically in persons with history of intravenous drug use (IDU). This article reports a fatal case of a 27-year-old patient with a known history of IDU, who presented with clinical symptoms concerning right-sided endocarditis as well as signs of acute respiratory distress syndrome. Finally, a detailed review of the literature is provided concerning the acute endocarditis of a tricuspid valve, especially associated with Serratia marcescens infection.

Alternative medicine supplements have become the second most common cause of drug-induced liver injury (DILI) in the US. Kratom is a herbal supplement that is popular for its psychotropic and opioid-like activity. It has become increasingly available in western countries, which often have no specific regulations on its use. However, reports of adverse events linked to kratom use have been increasing; it has been implicated in acute liver injury (mostly cholestatic), acute liver failure, organ dysfunction, toxicity, coma, seizures, and death. Herein, we aim to increase healthcare provider and public awareness of the risks posed by kratom and ultimately support increased regulation of its use.

Buspirone is commonly used to treat generalized anxiety disorder and demonstrates a limited side-effect profile compared to other anxiolytics. Buspirone is considered generally safe, and neuropsychiatric adverse reactions are uncommon. There are rare clinical case reports that suggest buspirone-induced psychosis. We present a case of buspirone worsening psychosis for a patient psychiatrically hospitalized for an episode of decompensated schizoaffective disorder. The patient had a primary diagnosis of schizoaffective disorder and was treated with antipsychotics during this hospitalization, but his symptoms worsened when buspirone was administered on two separate occasions. During the first trial of buspirone, the patient exhibited traits of increased aggression, odd behaviors, and paranoia. The buspirone was discontinued after the patient admitted to hiding his pills to later consume through nasal ingestion. The second trial resulted in repeated exacerbated symptoms of paranoia related to food and substantially decreased oral intake. Considering its complex mechanism of action, buspirone is suggested to derive its neuropharmacological effects through 5-HT1A receptors. However, the drug also has been found to mediate dopamine neurotransmission. Buspirone acts as an antagonist at presynaptic dopamine D2, D3, and D4 receptors. Yet, contrary to expected outcomes, it was unable to produce antipsychotic effects and instead resulted in a substantial increase in dopaminergic metabolites. The route of administration may also play a role in the enhancement of the buspirone\'s effects, particularly considering that after first-pass metabolism, buspirone has approximately 4% oral bioavailability. Intranasal administration of buspirone leads to faster drug absorption by direct transport from the nasal mucosa to the brain and increased bioavailability.
