We have successfully treated two patients with symptomatic pneumatosis cystoides intestinalis using a high FIO2 delivered by face mask, with administration interrupted at meal times. While we advocate oxygen therapy for this disease, caution must be taken to avoid the complications of high PaO2, namely proliferative and fibrotic lung changes. Close attention should be paid to the development of increasing cough, dyspnea and shortness of breath. As the frequency of the diagnosis of pneumatosis cystoides intestinalis increases, the success of high inspired oxygen as therapy should be recognized

An improved fiberoptic laryngoscope is connected to Timcke's stroboscope. The laryngoscope gives a magnified view of 2x and is prefocused from 5 cm to infinity. The combination of the stroboscope and the laryngoscope gives an excellent slow-motion view of the vocal fold movement.

The nasal hemangioma of pregnancy is an uncommon but impressive cause of epistaxis. One patient with this condition recently treated at the Keller Army Hospital, West Point, exemplifies the problems encountered in the diagnosis and treatment of this puzzling disorder

A photographic record of the appearance of the patient's face and neck preoperatively, and of the changes resulting from surgery is a most important aspect of facial cosmetic surgery. This report describes a practical, efficient system of photography performed in the surgeon's own office. The photographic equipment can be placed in a relatively small area at a total cost of well under $1000. The procedure described, when smoothly running can provide almost 99% efficacy in obtaining consistently good photographs with a minimum of effort and time spent by the surgeon and his office staff. The photographs are a precise, valuable record (medically and legally) of the patient's preoperative and postoperative appearances, and are important for the patient to see and for the surgeon to study. The patient is provided with a striking reminder of preoperative reality; the surgeon with insight into the progress of his surgical expertness

Neurilemomas of the tracheobronchial tree are exceedingly rare. In this article we report what is, to our knowledge, the 12th case--the third such case of tracheal origin. Clinical features are referable to airway obstruction and local pressure effects. The gross appearance is of an encapsulated lesion. Histologically, there is a proliferation of Schwann cells that are found in either an ordered, palisaded configuration (Antoni type A), or a disordered, loosely textured configuration (Antoni type B). The two types may coexist in a single lesion. Endoscopic removal of nonvascular tracheobronchial masses with follow-up, including periodic chest x-ray films, is advocated. Major surgery is reserved for malignant disease or benign disease not amenable to endoscopic excision.

Acoustic conductance and susceptance tympanograms were obtained at 220 and 660 Hz in 34 neonates. The neonates were categorized into three age groups (8-24 hours, 24-60 hours, and 60-96 hours). Single-peaked, double-peaked, and monotonically increasing tympanograms were found. Static values for conductance, susceptance, admittance, resistance, reactance and impedance at the lateral surface of the tympanic membrane were computed from the tympanograms. There were no significant differences in mean static values among the three groups. At 220 Hz, the individual static reactance values were usually smaller than the static resistance values and often assumed a positive sign. At 660 Hz, the individual static reactance values always assumed a negative sign and were approximately equal to the static resistance values. The single- and double-peaked tympanograms apparently were the result of previously identified interactions between static resistance and reactance values. The data were compared to those of infants and adults. Tympanograms at 220 Hz were obtained for 13 of the original subjects at the age of three to four months. The data collected in this group were consistent with those reported in the literature for the same age group.

Labyrinthitis ossificans is the pathological ossification of the membranous labyrinthine spaces in response to processes which are destructive of the membranous labyrinth or the endosteum of the otic capsule. It has been primarily a histopathologic diagnosis. Complex motion tomography however, allows a detailed view of the osseous labyrinth and permits the diagnosis in the living state. Radiologic documentation of labyrinthitis ossificans is objective evidence of a process destructive of the membranous labyrinth. It supports the likelihood of an absence of cochlear and vestibular function. It alerts the surgeon to the possible obliteration of key inner ear anatomical landmarks
