Four cases of obstructive sleep apnea associated with treatment-resistant mania

The authors describe four cases in which obstructive sleep apnea complicated the course and treatment of mania. An association between weight gain, obstructive sleep apnea, and lithium treatment is also illustrated.     

The Mini Rhytidectomy

A technique is described in which superficial musculoaponeurotic system (SMAS) is plicated from the deep temporal fascia above the zygoma to the level of the earlobe. This procedure requires only an extended preauricular incision. The neck is dealt with by liposuction. This technique is ideally suited to the younger patient requesting facelift and is based on a sound understanding of the anatomy of SMAS. The outcome of 35 patients who underwent this procedure during a 3.5-year period are described. There were no cases of facial nerve paresis or hair loss. There were no cases of skin necrosis but two patients developed small hematomas and one patient complained of a stretched preauricular scar. The mini facelift leads to a satisfactory result in the younger patient requesting rhytidectomy. The technique is simple and safe and can easily be performed on an ambulatory basis. Complications are uncommon and of a minor nature.     

Objective morphological assessment of macular hole surgery by scanning laser tomography

AIM—To assess the morphological change in retinal topography using a scanning laser tomographer following macular hole surgery. To compare the results of scanning laser tomography with clinical evaluation and visual function assessment.
METHODS—The sample for this pilot study comprised four eyes exhibiting different stages of macular hole formation preoperatively. Subjects were assessed preoperatively and at 1 and 3 months postoperatively. Each assessment included visual acuity, letter contrast sensitivity, clinical examination (including automated static perimetry), and scanning laser tomography. The Heidelberg retina tomograph (HRT) was used to acquire digitised scanning laser tomography images of the macula (10° and 20° fields). Surgery essentially comprised vitrectomy, peeling of the posterior hyaloid face, if still attached, and intraocular gas tamponade. The magnitude and significance of topographic change were determined postoperatively using the HRT topographic difference facility.
RESULTS—Topographic difference analysis of the right and left eyes of case 1 showed a significant reduction in the height of the retina postoperatively. Topographic difference analysis of case 2 showed no significant change in topography. Topographic difference analysis of case 3 showed a significant increase in the height of the retina postoperatively. Scanning laser tomography agreed with clinical assessment based upon fundus biomicroscopy in three of the four eyes studied; the postoperative closure of the stage 2 macular hole (as noted by clinical assessment) proved to be too small to reach statistical significance. Scanning laser tomography agreed with the assessment of visual function in two eyes; the agreement between scanning laser tomography and visual function depends, in part, on the stage of development of the macular hole.
CONCLUSION—Scanning laser tomography provides an objective evaluation of the outcome of macular hole surgery. Studies employing larger sample sizes are required to fully determine the clinical worth of the technique.

     

Important risk factors of allograft survival in cadaveric renal transplantation. A study of 426 patients.

Multiple risk factors contribute to the allograft survival of patients who have cadaveric renal transplantation. A retrospective review of 19 such factors in 426 patients identified race, DR match, B + DR match, number of transplants, and preservation time to have a significant influence. The parametric analysis confirmed the effect to be primarily in the early phase, i.e., first 6 months. All patients received cyclosporine with other methods of immunosuppression resulting in an overall 1-year graft survival rate of 66%. The overall 1-year graft survival rate in the white race was 73% and in the black race was 57% (p = 0.002). Allograft survival and DR match showed white recipients with a 1 DR match to have 75% survival at 1 year compared with 57% in the black patient (p = 0.009). If HLA B + DR match was considered, the white recipient allograft survival increased to 76%, 84%, and 88% for 1, 2, and 3 match kidneys by parametric analysis. Patients receiving first grafts had better graft survival (68%) than those undergoing retransplantation (58%) (p = 0.05). Organ preservation less than 12 hours influenced allograft survival with a 78% 1-year survival rate compared with 63% for kidneys with 12-18 hours of preservation. Despite the benefits of B + DR typing, short preservation time, and first transplants to the white recipient, the allograft survival in the black recipient remained uninfluenced by these parameters.     

Acute large bowel obstruction complicating acute pancreatitis

We have reported a rare case of acute large bowel obstruction complicating acute pancreatitis. The diagnosis of pancreatitis is often initially not considered in such patients, and is established only at laparotomy. The splenic flexure is the most common site of large bowel involvement. A proximal defunctioning colostomy is the preferred primary management.     

Flexor tendon injuries in children

Flexor tendon injuries in adults differ from those in children. 38 children (22 male and 16 female) with a mean age of 6.7 years were treated for flexor tendon injuries by primary suture and controlled mobilization between 1985 and 1992. 53 flexor tendons were injured (average 1.5 digits per patient) and the injury most commonly affected the little finger (23 patients). 60% of injuries occurred in zone 2. Using Lister's criteria, 82% achieved excellent or good results. Repair of both FDS and FDP was better than repair of FDP alone, even in zone 2. There were three tendon ruptures(all classified as poor results) and one other poor result occurredin a zone injury with an associated ulnar nerve palsy. The outcome after flexor tendon repair in children is better than in adults in our hands because rapid healing of tendons occurs in children. No child has yet required tenolysis because in children adhesions are more pliable. Both flexor tendons should be repaired irrespective of the zone of injury. A functional hand can be expected after flexor tendon repair in children.     

Benefits of quadruple immunosuppressive therapy in recipients of living related donor kidneys. A review of 855 operations.

Eight hundred fifty-five living related donor transplant recipients were analyzed according to 15 potential risk factors with regard to patient and graft survival according to immunosuppression. Group I, 1968 to 1983, (n = 440 patients) received azathioprine and prednisone; group II, 1984 to 1987, (n = 229 patients) received triple therapy--azathioprine, prednisone, and cyclosporine; and group III, 1988-1991, (n = 186 patients), quadruple therapy--azathioprine, prednisone, cyclosporine, and Minnesota antilymphocyte globulin. Three important risk factors included immunosuppression, tissue typing, and race. Groups II and III had improved allograft survival over group I (p = 0.03). Patients with two haplotype matches had similar survival in all three groups. Kidney survival in one-haplotype-matched recipients improved in group II and was equal to that of the two-haplotype-matched patients in group III. Cyclosporine improved allograft survival in both races when combined with azathioprine and prednisone. Quadruple therapy improved early survival in one-haplotype black patients, even though long-term results remained better in whites. Cyclosporine did not improve graft survival in two-haplotype recipients. The addition of cyclosporine and quadruple therapy did not increase morbidity and mortality rates.     

Tax-exempt challenges continue.

National attention to the tax-exempt status issue is not as acute as it has been in the last few years, but the challenges are continuing in a number of states. Hospital administrators and legal experts in Pennsylvania, the nation's flashpoint state on the issue, discuss what's going on and why.
