Unraveling the Potential of Electroanalgesia: A Literature Review of Current Therapeutics.

Neuropathic pain (NP), arising from dysfunction in the neurological system, poses a significant challenge in pain management due to its intricate origin and unpredictable response to conventional treatments. Electroanalgesia, a collection of techniques such as transcutaneous electric nerve stimulation (TENS), peripheral electrical nerve stimulation (PENS), spinal cord stimulation (SCS), deep brain stimulation (DBS), and electroacupuncture (EA), presents a potential alternative or complementary approach. This review brings together evidence from 56 studies to evaluate the effectiveness and safety of electroanalgesia in chronic NP. It discusses the mechanisms underlying NP, the indications for electroanalgesia, and the techniques utilized, emphasizing the diverse applications and potential benefits. However, despite its potential uses, electroanalgesia has its limitations, including variable effectiveness and potential adverse effects. Furthermore, the review recognizes the limitations of the methodology and the need for further research to refine treatment protocols and enhance the understanding of electroanalgesia's role in comprehensive pain management strategies.

Aerogenous metastases: a potential game changer in the diagnosis and management of primary lung adenocarcinoma.

OBJECTIVE: The purposes of this article are to summarize the relevant literature on aerogenous metastasis, explain the putative pathogenetic mechanism of aerogenous spread, present the characteristic imaging and pathologic features, and review the importance of aerogenous spread to staging and clinical management. CONCLUSION: Cumulative evidence suggests that aerogenous spread may exist and is underrecognized. Imaging features are helpful in differentiating possible aerogenous spread of tumor from hematogenous and lymphatic metastases and from synchronous primary tumors. The putative occurrence of intrapulmonary aerogenous metastasis of lung cancer has staging, management, and prognostic implications.

Primary adenocarcinoma of lung: a pictorial review of recent updates.

Primary adenocarcinoma of lung has replaced squamous cell carcinoma as the commonest histological subtype of lung cancer and the incidence of primary lung adenocarcinoma appears to be rising. Although the main factors behind this 'epidemic-like' situation are largely undiscovered, filter cigarettes appear to significantly contribute to this shift in the histopathological spectrum. The new multidisciplinary classification of adenocarcinoma of lung was introduced to address advances in clinical, pathological, radiological and molecular sciences. The purpose of this essay is to discuss various classes of lung adenocarcinoma in the new classification with their classical imaging features on computed tomography and summarise the recent advances in the field of radiology and review radiology recommendations.

Fatal midgut volvulus: a rare cause of gestational intestinal obstruction.

Malrotation is a congenital abnormality of the gastrointestinal tract that predisposes to midgut volvulus and can lead to small bowel infarction. Midgut volvulus is rare in adulthood and even rarer during pregnancy. If not diagnosed accurately, it carries a high-mortality rate. We present a case of 27-year-old woman with 33 weeks of gestation, who presented with acute abdomen and intrauterine fetal demise. CT angiogram with multidetector row scanner showed the midgut volvulus clearly and unequivocally. Unfortunately, the patient died of septicemia and extensive bowel infarction. CT angiogram images are presented here. To our knowledge, no similar case with gestational midgut volvulus and CT angiogram has been reported previously in the literature.

Diagnostic role of 64-slice multidetector row CT scan and CT venogram in cases of cerebral venous thrombosis.

Retrospective review of patients with cerebral venous thrombosis (CVT) detected by 64-slice multidetector row computed tomography (MDCT). To evaluate the role of CT scan as the primary modality of imaging in suspected cases of CVT. Between October 2006 and September 2007, 53 patients, suspected to have CVT, underwent CT scan of the brain. Out of these, 33 patients were included in the study, who underwent non-contrast CT (NCCT), CT venous angiogram (MDCTA) and magnetic resonance venogram. Two blinded readers evaluated the NCCT and MDCTA. Final diagnosis was obtained after consensus reading of all the imaging by the two readers. Out of the total 33 patients, 20 patients were detected to have thrombosis of one or more of the cerebral venous sinuses or veins, at the concluding consensus reading. MDCTA together with NCCT could identify thrombosis in all of the 20 patients, i.e., 100% sensitivity and specificity. Sixty-four-slice MDCTA together with NCCT provided 100% sensitivity and specificity for the identification of CVT. It can be considered as a cost-effective and widely available, primary imaging modality in emergency situations.

Giant renal angiomyolipoma with fatal hemorrhage due to a large pseudoaneurysm.

We report a case of giant renal angiomyolipoma (AML) with a large pseudoaneurysm causing fatal hemorrhage. A 60-year-old woman presented with right-sided abdominal pain. Sonographic examination revealed a large hyperechoic renal mass. CT examination of the abdomen revealed a 15-cm AML of the right kidney with a large hemorrhagic area within it. Subsequent color Doppler examination revealed a 2.9-cm pseudoaneurysm arising from the upper segmental branch of the right renal artery. The patient, who was about to undergo transcatheter embolization of the pseudoaneurysm, died from cardio-respiratory arrest. The autopsy findings confirmed a large right renal AML containing a thrombosed pseudoaneurysm and a large perinephric hematoma.
