Introduction of laparoscopically assisted vaginal hysterectomy in a private teaching community hospital.

STUDY OBJECTIVE: To compare laparoscopically assisted vaginal hysterectomy (LAVH) with traditional total abdominal hysterectomy (TAH) when the laparoscopic approach is introduced into a private hospital. DESIGN: During 1 year, 49 LAVHs were performed and compared with 51 consecutive TAHs using retrospective chart review and statistical analysis. SETTING: A private, university-affiliated, teaching hospital. PATIENTS: All patients undergoing LAVH, and the first 51 TAHs performed during the study year. MEASUREMENTS AND MAIN RESULTS: No major complications occurred in either group. Significant differences were observed in uterine weight (161 +/- 92 g vs 331 +/- 354 g), operating time (164 +/- 48 min vs 108 +/- 28 min), and hospital stay (2.93 +/- 1.21 days vs 4.00 +/- 1.54 days) for LAVH and TAH, respectively. Hospital charges for LAVH average $4074 more than for TAH, primarily due to the use of disposable laparoscopic equipment. CONCLUSIONS: Laparoscopically assisted vaginal hysterectomy may be performed safely in a private community hospital with appropriate surgeon credentialing and training. Modifying techniques to minimize the use of disposable equipment would make the procedure more cost effective.

Unusual site of spontaneous first-rib fracture: case report.

Spontaneous fractures of the first rib are uncommon and are usually thought to be associated with a malignant process. However, fatigue fractures of the first rib are being encountered increasingly in association with various physical activities. Typically, the fractures occur at the subclavian groove, but in the 48-year-old woman described in this report the fracture was unexpectedly situated in the posterior portion of the rib and was the result of snow shovelling, which was a new activity for the patient.

Case reports on psychosomatic eye disorders.

Symptoms of headache, floaters, blurred vision, eye strain may be respectable outward manifestations of secret fears or failure to adjust to life events. The work in this hospital of Mr W.S. Inman, ophthalmologist and psychoanalyst, has largely been forgotten. I will present case histories to show that the approach 'Let's have a chat about your problem' can reveal deep underlying tensions. The description of these by the patient, for the first time, to a neutral listener is usually curative. It takes longer than a detachment operation and can be more difficult than cataract surgery but the end result is a very grateful patient whose symptoms have been cured--by talking. We can easily dismiss these patients with 'Your problem is not ocular'. By spending time listening and being unafraid of their muddled lives, their confused sexuality and inadequate personal relationships, we can reach a wider range of patients to help, as Inman taught our predecessors. I find it rewarding.

Metastases to bone affected by Paget's disease. A report of three cases.

Three cases of metastatic disease in bone affected by Paget's disease are presented. The literature has been reviewed and a total of 26 similar cases found. The occurrence is rare compared to the frequency of sarcomatous transformation in Paget's disease, and low considering the frequency with which metastatic disease and Paget's disease each affect the elderly. This suggests that pagetic bone may resist the implantation of metastatic tumour cells.

Magnetic resonance imaging for ineffectual tarsal tunnel surgical treatment.

Tarsal tunnel syndrome (TTS) is an entrapment neuropathy caused by compression of the posterior tibial nerve beneath the ankle flexor retinaculum. Treatment of TTS consists of surgical release of the retinaculum. The failure rate is 10%-20%. Magnetic resonance (MR) imaging was used to evaluate a patient with an unsatisfactory response. MR imaging demonstrated incompleteness of the surgical release of the flexor retinaculum.

Normal magnetic resonance anatomy of the tarsal tunnel.

Images of five cadaver ankles and three normal volunteers were obtained in an attempt to delineate magnetic resonance (MR) anatomy of the tarsal tunnel. Multiplanar T1-weighted (TE 20 msec, TR 600 msec) scans were obtained of the cadaver specimens while T1 and T2 weighted (TE 20, 80 msec, TR 2000 msec) scans were obtained of the volunteer ankles. After imaging, the cadaver ankles were frozen, sectioned, photographed, and compared to the MR images in the transverse plane. The anatomical structures seen on the MR images correlated closely with the cadaver sections. The bony and soft tissue boundaries and contents of the tarsal tunnel could be imaged with detail easily sufficient to delineate all the major structures within it, including the posterior tibial nerve and its branches.

The value of internal oblique radiographs for posterolateral bone grafting of the tibia.

A 35 degrees internal oblique radiographic view of the tibia was used for the purpose of demonstrating posterolateral tibial bone grafts. This radiograph of the supine patient is made by internally rotating the affected leg 35 degrees obliquely toward the midline. This view eliminates superimposition of both the tibia and fibula on the graft. This method of radiographic evaluation has been found useful in visualization of graft margins intraoperatively and assessing bone graft incorporations in clinical follow-up evaluations. The authors recommend 35 degrees oblique views in preference to anteroposterior and lateral views for patients who have had posterolateral bone grafts of the tibia performed.

Inactivated influenza virus vaccines in man: a comparative study of subunit and split vaccines using two methods for assessment of antibody responses.

The serum antibody responses and reactions of volunteers to a trivalent subunit influenza virus vaccine prepared using cetyl trimethyl ammonium bromide (CTAB) or trivalent split vaccine prepared by ether-extraction, were essentially similar, although the antibody levels to the A/Brazil/78 (H1N1) components of the vaccine were greater in volunteers receiving the subunit preparation. Antibody responses to the vaccines were assessed using both the haemagglutination-inhibition (HI) and single radial haemolysis (SRH) tests. Although good correlation was found between the tests with respect to both antibody titres in individual sera and antibody responses in serum pairs to both A(H3N2 and H1N1) and B influenza viruses, the greater reliability of SRH, indicates this test should supplant the HI test for the routine measurement of antibody responses to influenza viruses.
