Nalbuphine has been increasingly used as a local anesthetic adjuvant to extend the duration of analgesia in brachial plexus block (BPB).

Acetaminophen (APAP) is a widely used pain reliever that can cause liver injury or liver failure in response to an overdose. Understanding the mechanisms of APAP-induced cell death is critical for identifying new therapeutic targets. In this respect it was hypothesized that hepatocytes die by oncotic necrosis, apoptosis, necroptosis, ferroptosis and more recently pyroptosis. The latter cell death is characterized by caspase-dependent gasdermin cleavage into a C-terminal and an N-terminal fragment, which forms pores in the plasma membrane. The gasdermin pores can release potassium, interleukin-1β (IL-1β), IL-18, and other small molecules in a sublytic phase, which can be the main function of the pores in certain cell types such as inflammatory cells. Alternatively, the process can progress to full lysis of the cell (pyroptosis) with extensive cell contents release. This review discusses the experimental evidence for the involvement of pyroptosis in APAP hepatotoxicity as well as the arguments against pyroptosis as a relevant mechanism of APAP-induced cell death in hepatocytes. Based on the critical evaluation of the currently available literature and understanding of the pathophysiology, it can be concluded that pyroptotic cell death is unlikely to be a relevant contributor to APAP-induced liver injury.

Porcelain gall bladder is an uncommon end-stage modification of chronic cholecystitis, with an incidence ranging from 0.06 to 0.8% along with a plausibility of malignant transformation.

Pituitary apoplexy is a rare and potentially life-threatening condition that usually occurs in the setting of a pre-existing pituitary tumor, which may be undiagnosed. There are a growing number of reports describing the pituitary apoplexy associated with coronavirus disease 2019 (COVID-19). We present the case of a 41-year-old man who presented with a gradually worsening headache for four days. It was a bilateral frontal headache of sharp quality with no radiation. He scored the headache as 9 out of 10 on the 10-point severity scale. He had no previous episodes of similar headaches. Fundoscopic examination revealed bilateral optic disc blurring suggestive of papilledema and cranial nerves examination revealed bilateral hemianopia. The patient was admitted for further investigation and management. As part of the admission protocol, the patent underwent a nasopharyngeal swab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which yielded positive results. Computed tomography demonstrated a large solid intrasellar mass with areas of high density suggesting hemorrhage along with a small amount of subarachnoid hemorrhage space in the left parietal lobe. The findings were consistent with pituitary apoplexy in the setting of pituitary macroadenoma. Intravenous hydrocortisone was administered. The patient underwent transsphenoidal surgical resection of the pituitary tumor, which resulted in significant improvement in the patient's symptoms. Pituitary apoplexy is a rare condition. The case suggests that COVID-19 may predispose to the development of pituitary apoplexy.

The primary objective of this study is to describe the most common radiological findings found on abdominal X-rays of patients with Crohn's disease (CD) presenting with acute abdominal pain.

Severe hypertension can accompany neurological symptoms without obvious signs of target organ damage. However, acute cerebrovascular events can also be a cause and consequence of severe hypertension. We therefore use US population-level data to determine prevalence and clinical characteristics of patients with severe hypertension and neurological complaints.

The VEPs provide an objective measure of brain function, analyzing integrity of visual processing. With patients affected with schizophrenia, the changes with the implementation of VEP are evident, such as symmetrical deceleration of the impulse and the continuance of latency, which points to a degenerative illness, suggesting the presence of optical neuritis or hemianopsia conjoined with mentioned intracranial illness.

To evaluate the effect of duloxetine when added to a multimodal analgesia regimen on posthemorrhoidectomy pain, opioid consumption, and side effects.

Cooking and heating with gas is common in Australian homes and is a risk factor for several important health problems; however, there is little awareness of these risks among doctors or the public. Gas stove use is estimated to cause 12% of childhood asthma in Australia.

Whipple's disease is a rare condition that, when not recognized and properly treated, can be fatal. A 49-year-old female presented with a five-month history of diarrhoea with watery stools seven times per day, nocturnal abdominal pain, asthenia, and a weight loss of 30% of her body mass in three months. The patient had a four-year medical history of bilateral mechanic gonalgia, arthralgia of the metacarpophalangeal and interphalangeal joints, and anaemia. The examination was remarkable for hyperpigmentation, along with a body mass index (BMI) of 15.8 kg/m. The diagnosis of Whipple's disease was made with upper gastrointestinal endoscopy, with typical histologic findings and a positive PCR for . Investigations also revealed cerebral demyelination and endocarditis in three valves. Treatment with intravenous ceftriaxone for four weeks and oral cotrimoxazole for one year resulted in complete resolution of the symptoms and endocarditis. This case report shows uncommon features of the disease and debates the challenging decisions toward diagnosis and effective treatment.
