What medication is used for pheochromocytoma?
For patients with pheochromocytoma, it is advisable to choose antihypertensive drugs during medication. Clinically, there are many types of antihypertensive drugs used to treat pheochromocytoma patients, such as alpha-adrenergic receptor blockers, beta-adrenergic receptor blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, vasodilators, catecholamine synthesis inhibitors, etc. These drugs can achieve desirable therapeutic effects. Of course, the main treatment for pheochromocytoma is through surgical methods. Only by effectively removing the tumor through surgery can a satisfactory therapeutic effect be achieved, fundamentally leading to a complete cure. (Please use medication under the guidance of a doctor.)
Does spinal bifida cause urinary incontinence during the day?
For patients with spina bifida, if it is occult spina bifida, they generally exhibit nocturnal enuresis, with rare instances of urinary incontinence during the day. For patients with manifest spina bifida, they may experience urinary incontinence during the day. Therefore, for patients with manifest spina bifida, it is usually recommended to perform surgical treatment at an early stage, with earlier surgery leading to better outcomes. It is generally advised for patients with manifest spina bifida to undergo surgery to effectively remove the locally protruding mass and to carefully clear the adherent nerve roots below, while monitoring changes in the patient's condition.
Can pheochromocytoma be cured?
Currently, with the continuous advancement of surgical techniques, pheochromocytomas can be treated promptly and effectively, achieving favorable outcomes. Once a pheochromocytoma is diagnosed and accurately localized, it is advisable to promptly proceed with surgical intervention. Removing the tumor surgically usually results in effective treatment outcomes. Before surgery, imaging studies and biochemical tests are used for the qualitative and locational diagnosis. After the nature and location of the tumor are clearly identified, the success rate of the surgery can also be increased. Pre-operative use of adrenergic receptor blockers can effectively manage the condition, leading to a reduction in blood pressure and lessening the load on the heart, thereby ensuring smooth conduct of the surgery.
Can neuroblastoma be treated?
Neuroblastoma is the most common tumor in childhood, and it is also the most common in infants and toddlers. Typically, neuroblastoma is a type of neuroendocrine tumor, clinically found often in the adrenal glands or in nervous tissues such as the neck, chest, and abdomen. Currently, neuroblastoma can be effectively classified according to its level of risk into low-risk, intermediate-risk, or high-risk groups. For patients in the low-risk group, surgical treatment can achieve satisfactory results; for patients in the intermediate-risk or high-risk groups, treatment often involves a combination of methods, yet still may not achieve satisfactory results.
Early symptoms of glioma
For patients with glioma, in the early stages of the disease, symptoms often manifest as mild headaches, dizziness, nausea, and vomiting. The symptoms are usually mild and tolerable for patients, and most patients do not pay enough attention, which can easily lead to missed and misdiagnosis. However, as the tumor volume increases, the patient's symptoms of headache, dizziness, and other discomforts gradually worsen, and may even show episodic outbreaks and a persistent worsening state. In addition to headaches and dizziness, some patients also exhibit significant motor dysfunction, exhibiting symptoms such as hemiplegia and aphasia. Patients with severe conditions may even experience widespread intracranial pressure increase, and life-threatening conditions due to the induction of brain herniation.
How to alleviate pain from hydrocephalus?
For patients with hydrocephalus, if there is significant pain, it is mostly caused by increased intracranial pressure, often seen in progressive hydrocephalus, or obstructive hydrocephalus. As the cerebrospinal fluid gradually increases and accumulates, it leads to the expansion of the ventricular system and causes extensive hydrocephalus, accompanied by gradually increasing intracranial pressure. To alleviate the pain, one might consider taking oral long-acting analgesics to help relieve the pain. Additionally, the use of mannitol or performing a lumbar puncture to release a small amount of cerebrospinal fluid may be considered to ease the pain. However, the key is to achieve the ultimate resolution of the disease through surgery.
Malignant manifestations of pheochromocytoma
For patients with pheochromocytoma, when malignant pheochromocytoma occurs and leads to hypertensive crisis, it often causes severe blood pressure increases, with blood pressure even reaching over 300 mmHg. At the same time, patients present with significant symptoms such as arrhythmia, tachycardia, palpitations, and shortness of breath. Some patients may also experience prominent chest pain, labored breathing, respiratory distress, and even marked sensations of urgency or anxiety, as well as a feeling of impending doom. Additionally, some patients may experience transient vascular constriction dysfunction due to severe hypertension, leading to cerebral hemorrhage.
Can hydrocephalus be treated?
Hydrocephalus can be effectively treated. Patients with hydrocephalus should first visit their local hospital for a cranial CT scan, and consider undergoing an MRI if necessary, to determine the primary causes and severity of the hydrocephalus and decide on the next treatment steps. For patients with underlying diseases, proactive treatment should be targeted at the cause, and effective surgical removal should be considered for intracranial space-occupying lesions. Patients with resistant hydrocephalus are advised to undergo regular check-ups and follow-ups, and for those with progressive obstructive hydrocephalus where the ventricular system is gradually expanding, surgical treatment is recommended.
How is neuroblastoma diagnosed?
For patients with neuroblastoma, diagnosis is primarily through the symptoms, signs, detailed physical examinations, medical history inquiries, and most importantly, radiological data, which includes CT scans or MRI of the head. Definitive diagnosis requires surgical removal of the tumor. A small amount of tumor tissue is retained after excision and used for pathological examination to confirm the diagnosis. Neuroblastoma is categorized as an epithelial-like malignant tumor, indicative of a high degree of malignancy. In most cases, early in the disease, the tumor adheres to surrounding tissues, which greatly complicates complete surgical removal, and most patients have a poor prognosis.
Is hydrocephalus serious?
Hydrocephalus is relatively serious. When hydrocephalus occurs, it gradually affects the patient's motor functions of the limbs, causing weakness in one or both sides, difficulty in lifting, walking impairments, difficulty performing fine motor actions, and ataxia. It may even lead to frequent falls. Additionally, there are significant cognitive impairments, characterized by reduced intelligence levels, decreased computational abilities, and even certain degrees of language dysfunctions. Patients may also exhibit significant personality changes, such as feelings of anxiety, depression, apathetic expressions, and a dislike for communication and interaction with others.
