Background:Normal pressure hydrocephalus (NPH) is a critical brain disorder in which excess Cerebrospinal Fluid (CSF) is accumulated in the brain’s ventricles causing damage or disruption of the brain tissues. Amongst various signs and symptoms, difficulty in walking, slurred speech, impaired decision making and critical thinking, and loss of bladder and bowl control are considered the hallmark features of NPH.Objective:The current review was aimed to present a comprehensive overview and critical appraisal of majorly employed neuroimaging techniques for rational diagnosis and effective monitoring of the effectiveness of the employed therapeutic intervention for NPH. Moreover, a critical overview of recent developments and utilization of pharmacological agents for the treatment of hydrocephalus has also been appraised.Results:Considering the complications associated with the shunt-based surgical operations, consistent monitoring of shunting via neuroimaging techniques hold greater clinical significance. Despite having extensive applicability of MRI and CT scan, these conventional neuroimaging techniques are associated with misdiagnosis or several health risks to patients. Recent advances in MRI (i.e., Sagittal-MRI, coronal-MRI, Time-SLIP (time-spatial-labeling-inversion-pulse), PC-MRI and diffusion-tensor-imaging (DTI)) have shown promising applicability in the diagnosis of NPH. Having associated with several adverse effects with surgical interventions, non-invasive approaches (pharmacological agents) have earned greater interest of scientists, medical professional, and healthcare providers. Amongst pharmacological agents, diuretics, isosorbide, osmotic agents, carbonic anhydrase inhibitors, glucocorticoids, NSAIDs, digoxin, and gold-198 have been employed for the management of NPH and prevention of secondary sensory/intellectual complications.Conclusion:Employment of rational diagnostic tool and therapeutic modalities avoids misleading diagnosis and sophisticated management of hydrocephalus by efficient reduction of Cerebrospinal Fluid (CSF) production, reduction of fibrotic and inflammatory cascades secondary to meningitis and hemorrhage, and protection of brain from further deterioration.

The great clinical success of chimeric antigen receptor T cell (CAR-T) and PD-1/PDL-1 inhibitor therapies suggests the drawing of a cancer immunotherapy age. However, a considerable proportion of cancer patients currently receive little benefit from these treatment modalities, indicating that multiple immunosuppressive mechanisms exist in the tumor microenvironment. In this review, we mainly discuss recent advances in small molecular regulators targeting G Protein-Coupled Receptors (GPCRs) that are associated with oncology immunomodulation, including chemokine receptors, purinergic receptors, prostaglandin E receptor EP4 and opioid receptors. Moreover, we outline how they affect tumor immunity and neoplasia by regulating immune cell recruitment and modulating tumor stromal cell biology. We also summarize the data from recent clinical advances in small molecular regulators targeting these GPCRs, in combination with immune checkpoints blockers, such as PD-1/PDL-1 and CTLA4 inhibitors, for cancer treatments.

Parkinson’s disease (PD) remains a common neurodegenerative movement disorder with significant morbidity, which is expected to increase worldwide in the coming decades. Since its initial description, much has been elucidated about its etiology, pathogenesis, and the role of genetic and environmental risk factors. Effective treatments, including surgical therapies, have been discovered. Despite these strides, many questions remain unanswered; PD remains an active research area with ongoing efforts to discover newer treatment modalities and identify neuroprotective strategies. As with many neurological conditions, there is an unequal distribution of health resources, resulting in some management challenges in low resource settings, especially sub-Saharan Africa (SSA). In this communication, we provide an overview of PD etiopathogenesis, including genetics and management strategies, including some recent advances with respect to treatment options and disease modification approaches. Finally, we discuss some challenges of PD management in low-resource settings and highlight efforts to turn the tide.

Keloids are pathological scars that grow over time and extend beyond the initial site of injury after impaired wound healing. These scars frequently recur and rarely regress. They are aesthetically disfiguring, can cause pain, itching, discomfort as well as psychological stress, often affecting quality of life. Many treatment modalities, including surgical and non-surgical, have been explored and have been reported to be beneficial; however, none have been absolutely satisfactory or optimal for the treatment of all keloid subtypes to date. This poses a major challenge to clinicians. Often, a combinational therapeutic approach appears to offer the best results with higher patient satisfaction compared to monotherapy. The aetiopathogenesis of keloids is not fully elucidated; however, with recent advances in molecular biology and genetics, insight is being gained on the complex process of scar formation and hence new therapeutic and management options for keloids. In this paper, we explore the literature and summarise the general concepts surrounding keloid development and review both current (corticosteroids, surgical excision, silicone-based products, pressure therapy, radiotherapy, cryotherapy, laser therapy, imiquimod and 5-fluorouracil) and emerging (stem cell therapy, mitomycin C, verapamil, interferons, bleomycin, botulinum toxin type A and angiotensin-converting enzyme inhibitors) treatments. Increased knowledge and understanding in this area may potentially lead to the discovery and development of novel therapeutic options that are more efficacious for all keloid types. Lay Summary [Formula: see text] Keloids are problematic scars that are difficult to treat and manage. The aetiopathogenesis of keloids is not clear; however, recent advances in molecular biology and genetics are beginning to shed light on the underlying mechanisms implicated in keloid scar formation which will hopefully lead to the development of treatment options for all keloid types. This review summarises current and emerging therapies.

Radiation therapy for three cases of suspect feline thymoma is described. The thymoma was controlled for 4 years in case no. 1. Case no. 2 responded well to radiation therapy but was euthanized after 2 months because of a nasal adenocarcinoma. Case no. 3 continues to do well more than 8 months after radiotherapy. Difficulties in diagnosing feline thymomas are discussed, and biological behavior as well as different treatment modalities of feline and human thymomas are compared.

Large cell neuroendocrine carcinoma (LCNEC) of the gallbladder is exceedingly rare. Only a few studies of pure gallbladder LCNEC without other histologic components have been reported in the literature. Therefore, this condition's biological behavior, appropriate treatment modalities, and overall patient prognosis remain largely unclear. In this report, we present a case involving resected pure gallbladder LCNEC. Additionally, we review relevant literature on LCNEC and discuss the clinical management of LCNEC, including histopathologic features. An 86-year-old woman presented with a gallbladder tumor that measured 25 mm on the body of the gallbladder that was incidentally detected by abdominal ultrasonography. The diagnosis of pure LCNEC without other histologic components was immunohistochemically confirmed after radical cholecystectomy and lymph node dissection in the hepatoduodenal ligament. The postoperative course was uneventful, and no evidence of recurrence or metastasis was observed after 6 months of follow-up. We reviewed 9 case reports describing pure LCNEC of the gallbladder, including the present case. Clinical symptoms and radiologic findings for pure LCNEC were nonspecific. The overall prognosis was poor, but early detection with complete resection might result in a relatively good prognosis.

Dupuytren’s disease (DD) is a common fibrotic disorder of the hand and can significantly impair hand function. Although the exact pathogenesis of this disorder remains to be elucidated, immunological, genetic and cellular factors likely interact. In this review, we summarise recent advances in the understanding of DD pathogenesis and look to the future for potential novel therapeutic targets. In addition, we discuss the therapeutic options in DD with a focus on the need for more rigorous evidence to allow a meaningful comparison of different treatment modalities.
