Giant Cell (Benign) Tumor of the Finger samer kareem 22,367 Views • 3 years ago

Giant cell tumors of the tendon sheath are common lesions and are the second most frequent tumors in the hand, after synovial cysts. They are diagnosed by means of clinical examination and complementary examinations (simple radiography and magnetic resonance). Erosion and invasion of the phalangeal bone affected may be seen on radiological examination. Magnetic resonance may show a “fluorescent or radiant effect” may be observed, caused by the high quantity of hemosiderin inside the tumor. Surgical treatment is the commonest practice, and complete excision is important for avoiding recurrence of the tumor, especially when bone invasion is observed on imaging examinations, which is generally related to greater tumor recurrence. In this paper, a case of a giant cell tumor of the tendon sheath in the middle phalanx of the third finger of a 45-year-old female patient is presented. This was successfully treated by means of surgery using a double access approach (dorsal and volar)

Pulmonary Arterial Hypertension
Pulmonary Arterial Hypertension samer kareem 1,714 Views • 3 years ago

The average time from symptom onset to diagnosis has been reported to be approximately 2 years. Despite recent attempts at increasing the awareness of pulmonary arterial hypertension (PAH), especially associated PAH (APAH), this delay in diagnosis has not changed appreciably in recent years. Early symptoms are nonspecific. Often, neither the patient nor the physician recognizes the presence of the disease, which leads to delays in diagnosis. Complicating matters, idiopathic PAH (IPAH) requires an extensive workup in an attempt to elucidate an identifiable cause of the elevated pulmonary artery pressure. The most common symptoms and their frequency, reported in a national prospective study, are as follows: Dyspnea (60% of patients) Weakness (19%) Recurrent syncope (13%) Additional symptoms include fatigue, lethargy, anorexia, chest pain, and right upper quadrant pain. Cough, hemoptysis, and hoarseness are less common symptoms. Women are more likely to be symptomatic than men.

Laparoscopic Liver Surgery
Laparoscopic Liver Surgery samer kareem 4,276 Views • 3 years ago

The most frequent incision utilized to open the abdomen for liver surgery is called a chevron incision. In this incision a cut is made on the abdomen below the rib cage. The cut starts under the armpit below the ribs on the right side of the abdomen and continues all the way across the abdomen to the opposite arm pit thereby the whole width of the abdomen is cut to provide access to the liver. The average length of the incision is approximately 24 to 30 inches. This is one of the longest incisions is utilized in abdominal surgery. The incision is frequently associated with significant discomfort after the surgery and in some patients the discomfort can continue for many months, particularly when some of the nerves in the abdominal wall have been cut during the surgery. Laparoscopic surgery provides advantages over open surgery for the liver since the chevron incision is completely avoided and the surgery is performed through tiny incisions. As a consequence the duration of stay in hospital, the amount and duration of post operative discomfort, and the length of recovery is much shorter after the laparoscopic procedure compared to open surgery

This procedure describes one of the most versatile approaches to the anterior skull base for large tumors of the sinonasal cavity. It may be used with or without a craniofacial resection. The benefits of this approach are: wide access around the tumor; good postoperative cosmesis; & decreased operative & postoperative morbidity. We have used this approach for many bilateral tumors of the nasal & sinus cavities that approach &/or invade the skull base & brain. This video show the resection of a large esthesioneuroblastoma.
