Results of uvulopalatopharyngoplasty after diagnostic workup with polysomnography and sleep endoscopy: a report of 136 snoring patients

We subjectively and objectively evaluated 136 patients with socially unacceptable snoring (SUS) or obstructive sleep apnoea syndrome (OSAS) treated with uvulopalatopharyngoplasty (UPPP) after a diagnostic workup by sleep registration (polysomnography, PSG) and sleep endoscopy. Of the 136 patients, there were 88 with OSAS and 48 with SUS. The results of the procedure were considered subjectively to be an improvement in 38 (79%) of the SUS patients and in 74 (84%) of the patients with OSAS. In 36 (40%) of the 88 patients with OSAS, repeating PSG postoperatively was considered unnecessary because of obvious improvement. Of the 52 patients with a measurement after UPPP, a decrease in the apnoea hypopnoea index (AHI) was found in 38 (73%; median decrease: 48%), and AHI dropped below 20 in 32 (62%). The apnoea index (AI) was available in 49 (56%) patients and was reduced in 31 (63%; median decrease: 73%). An overall positive result in the 88 patients with OSAS (combining available data on subjective and objective results) was therefore found in 61 (69%; positive subjective result and AHI <15) or 71 (81%; positive subjective result and decrease in AHI), respectively, depending on the definition. We conclude that after diagnostic workup by sleep registration and sleep endoscopy, the success rate of UPPP increases as compared to historical controls.     

Objective acoustic and aerodynamic measures of breathiness in paralytic dysphonia

This study was designed to determine which objective acoustic or aerodynamic parameters allowed a homogeneous group of patients with unilateral vocal fold paralysis (UVFP) to be distinguished from an age-matched and smoking-matched control group and to search for linear correlations between the objective parameters and the subjective breathiness ratings. Eight patients with recent-onset UVFP and 12 controls were prospectively studied. The acoustic parameters measured for the vowel /a/ at a comfortable frequency and intensity were: jitter, shimmer, harmonics-to-noise ratio, cepstral peak prominence, the difference between the levels of the first two harmonics and the relative energy above 6 kHz. Aerodynamic parameters included the mean flow rate during a sustained /a/ and intraoral pressure during the production of the phoneme /pi/. The long-term average spectrum was calculated for 40 s of text, and the relative average energies in four frequency bands were compared. Six judges rated a mid-/a/ sample using a five-parameter scale with four levels of severity. Nonparametric statistical analysis revealed significant differences ( P<.05) between the UVFP group and the control group for 14 of the 19 parameters studied. Correlations between the objective parameters and perceived breathiness differed in the two groups. Correlations were not always as expected as based on previous literature reports. These measurements provided an objective qualification of voice in patients with UVFP and successfully distinguished them from the normal controls. The objective acoustic and aerodynamic measurements had generally low linear correlations with breathiness ratings in the control group. Higher correlations were seen in the UVFP group, in which breathiness was best correlated with airflow measurements.

Surgery of basilar aneurysms associated with unexpected rupture of an internal carotid artery aneurysm

During a surgery of basilar aneurysms via the trans-sylvian approach, we encountered an arterial bleeding caused by rupture of an internal carotid artery aneurysm that had been difficult to diagnose before surgery, as it was a small and brood-neck aneurysm and mimicked arteriosclerosis. In spite of several surgical procedures, the surgical path at the basilar aneurysms became narrow, and we had to abandon the clipping of the aneurysms. Consideration of radiological and intraoperative findings was made for this case, demonstrating a pitfall that neurosurgeons may encounter during surgery.

Detection of medication nonadherence through review of pharmacy claims data.

The utility of pharmacy claims data in detecting improper medication use, medication changes, and formulary adherence was assessed. Pharmacists provided six months of pharmacy claims data to primary care physicians for patients on the day of their scheduled clinic appointments. Similar data, not supplied to physicians, were generated for a matched population of patients on the day of their scheduled clinic appointments. A blinded pharmacist abstracter reviewed dictated office notes for both control and treatment groups. Medication adherence and medication changes were assessed by the abstracter as well as the difference in total medication costs for each of the groups before and after the pharmacy claims data were supplied. Surveys were distributed to physicians to determine whether pharmaceutical care was improved by the pharmacy claims data. In the treatment group, physicians detected medication nonadherence in 30.5% of their patients, while the abstracter noted nonadherence in 58.1% of patients. Physicians failed to detect any nonadherence in the control group, but the abstractor detected nonadherence in 57.1% of these patients. Changes in medication regimens occurred more often in the treatment group (p < 0.001). The mean percentage of patients switched to formulary agents significantly differed between the treatment and control groups (27.7% versus 0.0%, respectively) (p < 0.001). There were no differences in median drug costs for either group before or after the pharmacy claims data were provided. Provision of pharmacy claims data to physicians helped them detect medication nonadherence, evaluate therapeutic duplication or omissions, increase formulary use, and reduce the time required to obtain an accurate medication history.     

Superior mesenteric artery bypass for chronic mesenteric ischaemia: a DGH experience

This article evaluates the results of single vessel bypass surgery for symptomatic chronic mesenteric ischaemia (CMI) in 6 patients undergoing a total of 8 superior mesenteric artery (SMA) bypass operations, all with good post-operative symptom relief. Post-prandial pain and weight loss was present in 5 out of 6 patients. Epigastric bruit was present in only two patients and 4 out of 6 patients had diarrhoea. The patients had varying degrees of peripheral vascular disease, ischaemic heart disease and hypertension. All patients had occlusion of the SMA on angiography and bypassing the occluded segment resulted in disappearance of the symptoms and weight gain. The vascular graft was sutured end to side to the front of the infra-renal aorta and end to side to the SMA, distal to the origin of the middle colic artery. Two patients had recurrence of symptoms due to graft occlusion at 3 and 4 years, respectively; they were successfully treated with repeat SMA bypass. There were no major complications or deaths related to the procedure in this study; one patient developed an incisional hernia requiring elective repair. Thus, early restoration of SMA circulation by bypass grafting in patients with CMI is sufficient to alleviate symptoms and prevent intestinal infarction with its high mortality rate.     

Replantation of the penis: a patient report

Replantation of the penis is an unusual case in this country and it is unlikely that most plastic and reconstructive surgeons or urologists will see one during their career. A successful repair of a self-inflicted amputation of the penis is presented. The unique anatomy of the penis pertinent to replantation is reviewed, and current concepts and recommendations in performing replantation of the penis are presented.     

Treatment of atrophoderma of Pasini and Pierini-associated hyperpigmentation with the Q-switched alexandrite laser: a clinical, histologic, and ultrastructural appraisal

BACKGROUND AND OBJECTIVE: Atrophoderma of Pasini and Pierini (APP) is an uncommon cutaneous disorder, with no known effective treatment, manifested by hyperpigmented patches that appear to be depressed compared with surrounding skin. This study investigated the effectiveness of the Q-switched alexandrite laser on a patient with extensive APP, and evaluated histopathologic and ultrastructural changes. STUDY DESIGN/MATERIALS AND METHODS:A man with stable APP underwent Q-switched alexandrite laser treatment to a patch on the trunk. Biopsies were obtained from treated and untreated sites of involvement. Light and transmission electron microscopic evaluation was performed to investigate melanosome number, size, and volume, as well as melanin granule number and size. RESULTS: After three treatment sessions, the treated area showed marked clinical improvement. Electron microscopy showed a 19% reduction in melanin granule number and size and a 65% reduction in melanosome number, size, and volume in larger melanosomes in treated compared with untreated sites. CONCLUSION: Treatment of APP with the Q-switched alexandrite laser results in clinical improvement. Electron microscopic evaluation suggests that the mechanism may be a reduction in the number, size, and volume of larger melanosomes as well as a decrement in melanin granule number and size.
