Intraocular lymphoma (IOL) is a rare and life-threatening condition whose aetiology is unclear. Blurred vision, reduced vision, and floaters are common initial symptoms. Posterior vitreous detachment and haemorrhage rarely occur. The authors present the case of a 79-year-old man who initially presented with a 3-month history of fever, night sweats, significant weight loss, bilateral peri-orbital haematoma, red eyes and retro-orbital headache. Physical examination revealed fever, bilateral peri-orbital haematoma, subconjunctival haemorrhage and palpable cervical lymphadenopathy. CT scans detected conical intra-orbital lesions, cervical adenomegalies, expansive lesions in the adrenal glands, and thrombosis of the splenomesenteric confluent and posterior segment of the right branch of the portal vein. These findings were suggestive of a lymphoproliferative disorder. Aspiration cytology of the adrenal mass and inguinal adenopathies was compatible with diffuse large B-cell lymphoma with areas of transformation to Burkitt's lymphoma. We describe a rare form of lymphoma, and a very unusual presentation of primary intraocular lymphoma with atypical symptoms.

High prevalence of chronic pain in elderly results in active search of new approaches for the effective and safe management of this category of patients. Antiepileptic drugs may provide analgesic affect in different types of chronic pain (mainly, in neuropathic pain). Variety of antiepileptics used as analgesics have variable efficacy and safety profile in elderly. «Old» antiepileptics (phenobarbital, clonazepam, ethosuximide, carbamazepine, phenytoin, valproate, etc.) and «new» (gabapentin, pregabalin, oxcarbazepine, lamotrigine, levetiracetam, topiramate, zonisamide, tiagabine) are considered in this review with insights on pharmacokinetic features of these drugs in elderly, profile of side effects, parameters of analgesic efficacy.

Pheochromocytomas are neuroendocrine tumors that produce catecholamines and can be difficult to diagnose. Bladder involvement is uncommon with pheochromocytoma. Hypertension (sometimes with hypertensive crisis coinciding with micturition), headache, hematuria and syncope, which are commonly associated with voiding, are the most prevalent symptoms. While transurethral resection may be performed in roughly 20% of patients, 70% require partial cystectomy and 10% require radical cystectomy. We present a case of pheochromocytoma with hypertension and syncope that was often associated with voiding, satisfactorily treated by partial cystectomy.

Pancreatic cancer is a kind of aggressive tumor famous for its lethality and intractability, and pancreatic ductal adenocarcinoma is the most common type. Patients with pancreatic cancer often suffer a rapid loss of weight and abdominal neuropathic pain in their early stages and then go through cachexia in the advanced stage. These features of patients are considered to be related to metabolic reprogramming of pancreatic cancer and abundant nerve innervation responsible for the pain. With increasing literature certifying the relationship between nerves and pancreatic ductal adenocarcinoma (PDAC), more evidence point out that innervation's role is not limited to neuropathic pain but explore its anti/pro-tumor functions in PDAC, especially the neural-metabolic crosstalks. This review aims to unite pancreatic cancer's innervation and metabolic rearrangements with terminated published articles. Hopefully, this article could explore the pathogenesis of PDAC and further promote promising detecting or therapeutic measurements for PDAC according to the lavish innervation in PDAC.

Sleep disorder dramatically affects people's physical and mental health. Here, we investigated the effect of preoperative sleep disorders on anesthesia recovery and postoperative pain in patients undergoing laparoscopic gynecological surgery under general anesthesia. 120 patients who underwent elective laparoscopic gynecological surgery under general anesthesia in Taizhou Central Hospital from November 2021 to March 2022 were included. According to the score of the Pittsburgh sleep quality index (PSQI), the participating patients were divided into four groups: control group (control group), mild sleep disorder group A (group A), moderate sleep disorder group B (group B), and severe sleep disorder group C (group C), with 30 patients in each group. The changes of mean arterial pressure (MAP) and heart rate (HR) at different time points, operation time, anesthesia time, extubation time, the time when Aldrete score reached 10 points, visual analog score (VAS) serum interleukin-6 (IL-6), interleukin-10 (IL-10), and tumor necrosis factor- (TNF-) were compared among different groups. Our study demonstrated that there were no significant differences in MAP and HR among the four groups at the same time points (all > 0.05). Significant differences in the time of extubation and Aldrete score reaching 10 points had been found among the four groups (all < 0.001), indicating more sleep disorder induced longer extubation and recovery time. There were significant differences in VAS scores among the four groups at both different and the same time points (all < 0.001), suggesting more sleep disorders induced more pain in the sufferers. Serum IL-6 levels were significantly higher in the three sleep disorder groups than the control group at 6 h and 24 h after the operation (all < 0.05), while group C has the highest IL-6 levels as compared to the other group ( = 0.09 and < 0.001, respectively). At 6 h after operation, serum levels of TNF- in group C were significantly higher than in the control group ( = 0.044), but no significant differences were found in the other two groups (all > 0.05). Positive correlation with preoperative PSQI score has been found with the times of extubation, the time of Aldrete score reaching 10 points, the VAS at 1 h, 6 h, and 24 h after operation, the level of serum IL-6 at 1 day before operation and 6 h and 24 h after operation, and the TNF- at 6 h and 24 h after operation (all < 0.001). The present study showed that the degree of preoperative sleep disorders could affect the quality of postoperative awakening and pain of patients undergoing laparoscopic gynecological surgery under general anesthesia, which might be associated with the aggravation of inflammatory reactions in the body.

Dengue viral infection is considered endemic in Ecuador. It is more frequent during winter, caused by an RNA virus in the Flavivirus group. Its presentation can range from an asymptomatic state to hemorrhagic fever with shock signs. Acute pancreatitis could be a rare form of acute abdomen presentation associated with dengue virus infection. This case illustrates a 26-year-old man who presents to the hospital with cramp-like pain in the epigastrium and radiation to the right upper quadrant, accompanied by nausea and vomiting. He also endorsed additional symptoms such as throbbing-like headache, myoarthralgias, and fever of 40.4°C (104.72°F). Laboratory tests revealed elevated hematocrit, thrombocytopenia, elevated pancreatic enzymes, transaminitis, elevated alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT). Ultrasonography of the abdomen revealed hepatic steatosis, free fluid in the abdominal cavity, and small bilateral pleural effusions. Additional testing revealed IgM and IgG antibodies positivity to dengue virus. The patient was treated conservatively with intravenous (IV) fluid hydration and bowel rest. Acute pancreatitis should be considered when a patient presents with a suspected acute abdomen in the emergency department, and a detailed medical history is necessary to make a correct approach to the differential diagnosis.

Interleukin-6 (IL-6) is a pro-inflammatory and bone-resorptive cytokine that also regulates bone formation. We previously showed that prostaglandin E1 (PGE1) induces the synthesis of IL-6 by activating p44/p42 mitogen-activated protein kinase (MAPK), stress-activated protein kinase/c-Jun N-terminal kinase (SAPK/JNK), and p38 MAPK in osteoblast-like MC3T3-E1 cells. In the present study, we investigated whether heat shock protein 70 (HSP70), a molecular chaperone that coordinates protein folding and homeostasis, affects PGE1-stimulated IL-6 synthesis in MC3T3-E1 cells through the MAPK activation. The osteoblast-like MC3T3-E1 cells were treated with HSP70 inhibitors-VER-155008 and YM-08-, PD98059, SB203580 or SP600125 and then stimulated with PGE1. IL-6 synthesis was evaluated using an IL-6 enzyme-linked immunosorbent assay kit. IL-6 mRNA expression was measured by real-time RT-PCR. The phosphorylation of p38 MAPK was evaluated by Western blotting. We found that VER-155008, an HSP70 inhibitor, enhanced the PGE1-stimulated IL-6 release and IL-6 mRNA expression. YM-08, another HSP70 inhibitor, also enhanced PGE1-stimulated IL-6 release. PD98059, a p44/p42 MAPK inhibitor, and SP600125, a SAPK/JNK inhibitor, upregulated PGE1-stimulated IL-6 release. On the other hand, SB203580, a p38 MAPK inhibitor, suppressed PGE1-stimulated IL-6 release. YM-08 stimulated the PGE1-induced phosphorylation of p38 MAPK. SB203580 suppressed the amplification by YM-08 of the PGE1-stimulated IL-6 release. Our results suggest that HSP70 inhibitors upregulate the PGE1-stimulated IL-6 synthesis through p38 MAPK in osteoblasts and therefore affect bone remodeling.
