On rare occasions, emergency tracheostomy is indicated to establish an airway. Using a large bore needle as a guide, tracheal intubation is assured with minimal damage to vital structures in the neck.

Continuous suction, negative pressure drains serve as an excellent "atmospheric bandage" in subcutaneous surgical procedures while helping to expedite wound healing and impede complications secondary to tissue plane dissection.

A new filtered sump tube has been designed for drainage of collections of fluids from wounds without the danger of infection by airborne contaminants. A two-staged filter has been attached to the vent lumen that removes particulate matter and bacteria from the air that passes through the filter. A clinical evaluation of this tube confirms the superiority of sump drainage as compared with closed suction drainage in the removal of fluids from wounds or cavities.

Contiguous cervical and deltopectoral flaps have several advantages in reconstruction of the head and neck after extirpation of cancer. The cervical skin provides an excellent color match for facial skin, and nonhair-bearing skin is available if lining of the oral cavity is required. The deltopectoral flap provides superior coverage for the carotid artery.

In the majority of patients in this series of 1,000, acute abdominal pain was due to conditions that required neither surgical intervention nor hospitalization. Eleven of the 1,000 patients had an early missed diagnosis in the emergency clinic for which a subsequent operation was needed, and twenty underwent an operation which subsequent diagnosis showed was not required. All false-negative evaluations occurred in patients with early appendicitis or small bowel obstruction. Most false-positive results were due to acute infections of the female genitourinary tract in patients operated on to exclude appendicitis or a tubo-ovarian abscess. The following factors help identify the high risk patient with an acute surgical abdomen: (1) pain for less than 48 hours; (2) pain followed by vomiting; (3) guarding and rebound tenderness on physical examination; (4) advanced age; (5) a prior surgical procedure. The presence of these features demands careful evaluation and a liberal policy of admission and observation. White blood cell counts, body temperature, and abnormal abdominal roentgenograms may add confirmatory evidence but are not particularly helpful as screening devices.

An analysis of twenty-six cases of epidermoid carcinoma of the anus from the University of Virginia Medical Center and 1,060 cases from the surgical literature has been presented. We believe this review justifies the following conclusions. (1) Considerable delay in diagnosis frequently occurs, adversely affecting the prognosis of patients with this disease. (2) Abdominoperineal resection remains the treatment of choice. Wide local excision is inadequate for most lesions, and should be reserved for lesions of the anal verge less than 2 cm in diameter with favorable histology, that is, low grade of malignancy. (3) Large lesions and those with a high grade of malignancy are associated with a poor prognosis, but even these patients may sometimes be cured with aggressive surgical excision. (4) Synchronous inguinal node metastases are associated with a poor prognosis, but an occasional patient may be cured by iliofemoral node dissection. (5) Iliofemoral node dissection is indicated for metachronous inguinal node metastases in the absence of distant spread. (6) Iliofemoral node dissection should not be performed if these nodes are not clinically involved with metastases. Approximately 70 per cent of these patients will not need this procedure and would therefore have this resection and its attendant morbidity unnecessarily.

The pectoralis major muscle has overcome many of the complications of augmentation mammoplasty after subcutaneous mastectomy. It places the implant deep to prevent skin slough and irregularities in skin surface contour. The flap eliminates abnormal implant posture when the pectoralis major is contracted. The short (5 to 7 days) staging of the procedure allows sealing of the pocket from external innoculation of bacteria while preventing unretrievable skin and nipple shrinkage.

Nonoperative management of fingertip pulp amputations has been employed in eighteen adults. After wound cleansing and debridement, the wound was covered by an occlusive dressing. Healing of the amputated fingertip occurred within four weeks. The healed fingertip had an excellent sensory perception, normal range of motion and an acceptable cosmetic appearance. This satisfactory outcome was realized with less than ten days lost from work.

There is ample evidence from this retrospective comparison to indicate that emphysematous cholecystitis does merit clinical distinction apart from acute cholecystitis. It is an acute infection of the gallbladder caused by a specific group of bacteria that may be aided by some aspect of local ischemia. Cholelithiasis does not seem to be a major factor in the pathogenesis of emphysematous cholecystitis, and this, in association with some dependence upon ischemia, may account for the predominance of this disease in males rather than females. Gangrene is a common feature of the pathologic process, and thus it is not surprising that the diagnosis of emphysematous cholecystitis implies a risk of gallbladder perforation that is five times that expected from ordinary acute cholecystitis. The key to identifying this disease is the plain abdominal roentgenogram which in most instances will make the diagnosis and provide an impetus for early operative intervention.
