Diquat is a kind of conductive contact-killing herbicides. The damage of central nervous system is relatively common, but the peripheral neuropathy caused by diquat has not been reported yet. In September 2021, we treated a patient with diquat poisoning. During the hospitalization, the patient was diagnosed with peripheral neuropathy. Therapy for peripheral nerve injury was given on the basis of conventional treatment of poisoning. The patient was discharged after his condition was stable. The follow-up showed that the peripheral neuropathy of patient was better than before. According to the condition of this patient, it is suggested that we should not only protect the function of gastrointestinal tract, liver, kidney, and central nervous system early, but should also pay attention to the damage of peripheral nervous system in clinical work. We should intervene earlier to improve the prognosis of patients.

OBJECTIVE: To investigate the protective effect and potential mechanism of tubastatin A (TubA), a specific inhibitor of histone deacetylase 6 (HDAC6), on renal and intestinal injuries after cardiopulmonary resuscitation (CPR) in swine. METHODS: Twenty-five healthy male white swine were divided into Sham group (n = 6), CPR model group (n = 10) and TubA intervention group (n = 9) using a random number table. The porcine model of CPR was reproduced by 9-minute cardiac arrest induced by electrical stimulation via right ventricle followed by 6-minute CPR. The animals in the Sham group only underwent the regular operation including endotracheal intubation, catheterization, and anesthetic monitoring. At 5 minutes after successful resuscitation, a dose of 4.5 mg/kg of TubA was infused via the femoral vein within 1 hour in the TubA intervention group. The same volume of normal saline was infused in the Sham and CPR model groups. Venous samples were collected before modeling and 1, 2, 4, 24 hours after resuscitation, and the levels of serum creatinine (SCr), blood urea nitrogen (BUN), intestinal fatty acid binding protein (I-FABP) and diamine oxidase (DAO) in serum were determined by enzyme-linked immunoadsordent assay (ELISA). At 24 hours after resuscitation, the upper pole of left kidney and terminal ileum were harvested to detect cell apoptosis by TdT-mediated dUTP-biotin nick end labeling (TUNEL), and the expression levels of receptor-interacting protein 3 (RIP3) and mixed lineage kinase domain-like protein (MLKL) were detected by Western blotting. RESULTS: After resuscitation, renal dysfunction and intestinal mucous injury were observed in the CPR model and TubA intervention groups when compared with the Sham group, which was indicated by significantly increased levels of SCr, BUN, I-FABP and DAO in serum. However, the serum levels of SCr and DAO starting 1 hour after resuscitation, the serum levels of BUN starting 2 hours after resuscitation, and the serum levels of I-FABP starting 4 hours after resuscitation were significantly decreased in the TubA intervention group when compared with the CPR model group [1-hour SCr (μmol/L): 87±6 vs. 122±7, 1-hour DAO (kU/L): 8.1±1.2 vs. 10.3±0.8, 2-hour BUN (mmol/L): 12.3±1.2 vs. 14.7±1.3, 4-hour I-FABP (ng/L): 661±39 vs. 751±38, all P < 0.05]. The detection of tissue samples indicated that cell apoptosis and necroptosis in the kidney and intestine at 24 hours after resuscitation were significantly greater in the CPR model and TubA intervention groups when compared with the Sham group, which were indicated by significantly increased apoptotic index and markedly elevated expression levels of RIP3 and MLKL. Nevertheless, compared with the CPR model group, renal and intestinal apoptotic indexes at 24 hours after resuscitation in the TubA intervention group were significantly decreased [renal apoptosis index: (21.4±4.6)% vs. (55.2±9.5)%, intestinal apoptosis index: (21.3±4.5)% vs. (50.9±7.0)%, both P < 0.05], and the expression levels of RIP3 and MLKL were significantly reduced [renal tissue: RIP3 protein (RIP3/GAPDH) was 1.11±0.07 vs. 1.39±0.17, MLKL protein (MLKL/GAPDH) was 1.20±0.14 vs. 1.51±0.26; intestinal tissue: RIP3 protein (RIP3/GAPDH) was 1.24±0.18 vs. 1.69±0.28, MLKL protein (MLKL/GAPDH) was 1.38±0.15 vs. 1.80±0.26, all P < 0.05]. CONCLUSIONS TubA has the protective effect on alleviating post-resuscitation renal dysfunction and intestinal mucous injury, and its mechanism may be related to inhibition of cell apoptosis and necroptosis.

PURPOSE: Adrenal gland injuries in trauma are rare and usually misdiagnosed or underestimated in an emergency setting because they are asymptomatic and associated with severe abdominal injuries. This paper reviews the clinical characteristics of adrenal injuries. METHODS: A retrospective analysis of trauma patients who visited the authors' emergency center was performed from March, 2010 to December, 2017. The patient demographic data, injury mechanism & associated injuries, injury severity score, hospital stay, and mortality were retrieved and analyzed. RESULTS: Adrenal gland injuries were found in 52 patients: 73.1% (n=38) were males and the mean age was 43.6 years. Of the patients, 84.6% (n=44) had ISS ≥15. Right adrenal gland injuries occurred in 82.7% (n=43). The mechanism of injury was falls in 30.8% (n=16), motor vehicle accidents in 25.0% (n=13), and pedestrian accidents in 23.1% (n=12). Associated injures were liver injury (58.5%), rib fracture (52.8%), kidney injury (24.5%), pelvic bone fracture (20.8%), spine fracture (28.3%), and spleen injury (13.2%). The mean hospital stay was 34.2 days, and the intensive care unit stay was 9 days. The mortality rate was 3.8% (n=2). CONCLUSION: Adrenal gland injuries are common in males and frequent in the right side. Falls are the leading cause of injury. Most injuries have an associated injury at the abdominal or thoracic region. Adrenal injury is accompanied by high injury severity but showed a good prognosis.

PURPOSE: We present our experience involving the management of this disease, identifying prognostic factors affecting treatment outcomes. METHODS: The patients treated for Fournier gangrene at our institution were retrospectively reviewed. Data collected included demographics, extent of soft tissue necrosis, predisposing factors, etiological factors, laboratory values, and treatment outcomes. The severity index and score were calculated. Multivariate regression analysis was used to determine the association between potential predictors and clinical outcomes. RESULTS: A total of 41 patients (male:female = 33:8) were studied. The mean age was 54.4 years (range, 24–79 years). The most common predisposing factor was diabetes mellitus (n = 19, 46.3%). Sixteen patients (39.0%) were current smokers. Seven patients had chronic kidney disease. The most frequent etiology was urogenital lesion (41.5%). The mortality rate was 22.0% (n = 9). Multivariate regression analyses showed that extension of necrosis beyond perineal/inguinal area and pre-existing chronic kidney disease were significant and independent predictors of mortality. Extension of necrosis beyond perineal/inguinal area was a significant predictor of increased duration in the intensive care unit and hospital stay. In addition, pre-existing chronic kidney disease was a significant predictor of flap reconstruction in the wound. CONCLUSION: Fournier gangrene with extensive soft tissue necrosis and pre-existing chronic kidney disease was associated with poor prognosis and complexity of patient management. Early recognition of dissemination and premorbid renal function is essential to reduce mortality and establish a management plan for this disease.

STUDY DESIGN: Case report. OBJECTIVES: To report 2 cases of acute lumbar paraspinal compartment syndrome due to weightlifting. SUMMARY OF LITERATURE REVIEW: Acute lumbar paraspinal compartment syndrome is very rare, but it causes muscle necrosis and acute renal failure. Therefore, it should be treated immediately. MATERIALS AND METHODS: A 31-year-old male patient and a 30-year-old male patient visited the emergency room due to severe back pain. The left paraspinal compartment pressure of the 31-year-old patient was measured as 35 mm Hg using the Whitesides technique. The paraspinal compartment pressure of the 30-year-old patient was measured as 22 mm Hg on the left side and 30 mm Hg on the right side. We diagnosed acute lumbar paraspinal compartment syndrome and performed a fasciotomy. This study received Institutional Review Board approval (ID: SC18ZESE0032). RESULTS: Lab findings improved after fasciotomy. The operative wounds healed after fasciocutaneous flap placement. CONCLUSIONS: Acute lumbar paraspinal compartment syndrome is very rare, but should be considered in patients with severe back pain.

In physically and mentally impaired elderly individuals, sexual dysfunction caused by aging or illness has not received proper therapeutic attention. Moreover, the most important reason for the elderly not to express their sexual desires is the presence of social prejudice and lack of awareness regarding the sexual behavior of the aged. In particular, patients in long-term care facilities may be have less interest in or awareness of these issues than the general population. Sex among the aged is both a biological and sociocultural phenomenon, and sexual problems experienced by the elderly should be approached with this in mind. Patients in long-term care facilities often receive therapy for various diseases that can cause sexual problems. Relatively common underlying diseases affecting sexual function in long-term care patients are dementia, stroke, aging, spinal cord injury, and malignancy, as well as chronic diseases such as diabetes mellitus, hypertension, and chronic renal failure. Inappropriate sexual behavior in patients with dementia poses ethical problems. However, no guidelines exist regarding treatment for improper sexual behavior. Elderly individuals in long-term care facilities often experience difficulties having a satisfactory sex life even if they have a spouse. To facilitate a healthy sex life among elderly individuals in long-term care, both a sufficient understanding of sexuality and sexual behavior and appropriate institutional strategies are needed.

A 35-year-old man presented with progressive dyspnea and hemoptysis. His blood pressure was 230/140 mmHg and serum creatinine level was 20.13 mg/dL. Chest radiography and computed tomography revealed pulmonary hemorrhage. His renal function was low, thus emergent renal replacement therapy was required. Malignant hypertension and acute kidney injury were diagnosed, and antihypertensive therapy and hemodialysis started immediately. Renal biopsy was performed to examine the underlying disease. Typical pathological changes of malignant hypertension, fibrinoid necrosis of the afferent arterioles, and proliferative endoarteritis at the interlobular arteries were observed. His renal function improved gradually and pulmonary hemorrhage completely disappeared with administration of antihypertensive agents. Here, we report this rare case of malignant hypertension with pulmonary alveolar hemorrhage and speculate that the hemorrhage may be related to vascular injuries at the alveolar capillary level caused by malignant hypertension.

Neuro-tracing approach is a great option to study innervation of the visceral organs including the kidneys. Important factors contributing to the success of this technique include the choice of a neuro-tracer, and delivery methods to result in successful labeling of peripheral sensory and motor ganglia. The neuro-tracer is usually applied directly to the kidney accessed via a surgical opening of the abdominal wall under deep anesthesia. A series of local microinjections of the dye are performed followed by a wound closure, and recovery period from the surgery. An extra care should be taken to prevent neuro-tracer spillage and accidental labeling of the surrounding organs during injections of the dye. Retrograde neuro-tracers like Fast Blue do not cross synapses, therefore, only neuronal bodies located within dorsal root ganglion neurons and major peripheral ganglia will be labeled by this approach. Retrogradely labeled peripheral neurons could be freshly isolated and dissociated for electrophysiological recordings and biochemical analyses (gene and protein expression), whereas the whole fixed ganglia could be sectioned to undergo immunohisto- and immunocytochemical targeted staining.

Rhabdomyolysis is most frequently caused by soft tissue injury with trauma to the extremities. Non-traumatic rhabdomyolysis may be caused by alcohol or drug abuse, infection, collagen disease, or intensive exercise, but incidence is low. In particular, rhabdomyolysis resulting from carbon monoxide poisoning is especially rare. If caught before death, carbon monoxide poisoning has been shown to cause severe muscle necrosis and severe muscle damage leading to acute renal failure. In cases of carbon-monoxide-induced rhabdomyolsis leading to acute compartment syndrome in the buttocks and sciatic nerve injury are rare. We have experience treating patients with acute compartment syndrome due to rhabdomyolysis following carbon monoxide poisoning. We report the characteristic features of muscle necrosis observed during a decompression operation and magnetic resonance imaging findings with a one-year follow-up in addition to a review of the literature.
