The use of bone scan to evaluate total hip prostheses. A preliminary study

The authors conducted a clinical and radiographic study on a group of 43 patients with hip arthroprostheses selected from the three-year period from 1984 to 1987, characterized by no immediate postoperative complications, no positional defects on X-ray examination, and with a Renther test greater than 1. Prostheses were cemented, cementless and combined. Scintigraphy was evaluated for areas of subdivision in the proximal end of the femur and acetabulum, making a semi-quantitative comparison of the intensity of captation of each area with that of the skull and sacroiliac synchondrosis. The authors emphasize that this procedure is both reliable and easy for the early determination (pre-clinical and pre-radiographic) of any complications. A scintigraphic examination of the single areas was also capable of revealing the site and entity of prosthetic bone-to-implant interactions. According to the results reported, PCA prostheses seem to be characterized by better biocompatibility.     

Endometriosis: Leuprolide in a 3-monthly versus a monthly depot formulation for the treatment of symptomatic endometriosis: a pilot study

An open-label randomized pilot study was conducted to evaluatethe efficacy and acceptability of 6 months treatment with leuprolidein a 3-monthly versus a monthly i.m. depot injection for therelief of chronic pelvic pain in women with endometriosis. Atotal of 30 women aged 18-38 years were allocated to the 3-monthlydepot arm (n = 15) or to the monthly depot arm (n = 15) afterlaparoscopic diagnosis of pelvic endometriosis. Mean (SD) deepdys-pareunia scores according to a 0–3 point verbal ratingscale decreased from 1.8 (0.9) at baseline to 1.3 (0.7) at theend of treatment in the 3-monthly depot group and from 2.1 (1.2)to 1–3 (0.7) in the monthly depot group. Correspondingvalues in non-menstrual pain scores fell from 2.1 (0.6) to 1.1(03), and from 2.1 (0.8) to 1.2 (0.4) respectively, withoutstatistically significant differences between the groups. Serumluteinizing hormone (LH) and 17-oestradiol concentrations weresignificantly suppressed at 12 and 24 weeks compared with baselinevalues, without differences between the groups. The monthlydepot caused a slightly more marked inhibition of serum folliclestimulating hormone (FSH) levels with respect to the 3-monthlypreparation. Mean (SD) endometriosis scores at baseline andat 6-month follow-up laparoscopy were respectively 32.8 (25.1)and 12.2 (9.3) in the 3-monthly depot group and 29.0 (22.7)and 13.1 (15.3) in the monthly depot group (paired Mest, P 0.05). Mean percentage decrease in lumbar spine bone mineraldensity was 5.2% in the former and 4.9% in the latter subjects.In the 3-monthly depot group, 13 women graded the tolerabilityof their treatment schedule as ‘good’ compared withseven in the monthly depot group (² = 5.40, P = 0.02).     

‘Nocturnal groaning’: just a sound or parasomnia?

We describe the clinical and polysomnographic characteristics of 12 patients complaining of expiratory groaning during sleep. Groaning occurred almost exclusively during rapid eye movement sleep. We reviewed all the literature cases, obtaining a total sample of 27 patients. There is no evident association with any predisposing factors or underlying disease. The results obtained from empirical treatment, including drugs and CPAP, are unsatisfactory. The origins of nocturnal groaning, as well as the long-term prognosis, remained unexplained.     

Surgery: Adenomyosis at hysterectomy: a study on frequency distribution and patient characteristics

To evaluate the prevalence and risk factors for adenomyosis,the clinical records of consecutive women undergoing hysterectomyduring a 3 year period were retrieved. Data were collected onindication for the intervention, general sociodemographic characteristicsof the patients, age at menarche, parity, abortions, and menopausalstatus at surgery. Adenomyosis was diagnosed in 332 of the 1334cases (24.9%). The condition was present in 146 of the 627 patients(23.3%) with fibroids and menorrhagia, 68 of the 265 (25.7%)with prolapse, 21 of the 98 (21.4%) with ovarian cysts, 19 ofthe 100 (19%) with cervical cancer, 31 of the 110 (28.2%) withendometrial cancer, 16 of the 57 (28.1%) with ovarian cancer,and 19 of the 77 (24.7%) with miscellaneous indications. Thesedifferences were not statistically significant (x²₆ = 11.14).In comparison with nulliparous women, the odds ratio was 1.3and 1.5 respectively in women with one and two births (x²₁ trend= 5.76, P < 0.05). No relationship was found between ageat surgery, age at menarche, indications for surgery, menopausalstatus at intervention, and presence of endometriosis. Our findingsdo not support the notion that adenomyosis is more frequentlyrelated to particular clinical conditions, and suggest thatparity may be associated with an increased frequency of adenomyosis.

Prevalence and disability of comorbid social phobia and obsessive–compulsive disorder in patients with panic disorder and generalized anxiety disorder

Objective. Generalized anxiety disorder (GAD) and panic disorder (PD) are disabling conditions, often comorbid with other anxiety disorders. The present study was aimed to assess prevalence and related disability of comorbid social phobia (SP) and obsessive–compulsive disorder (OCD) in 115 patients with GAD (57) or PD (58). Methods. Patients were classified as having threshold, subthreshold, or no comorbidity, and related prevalence rates, as well as disability (Sheehan Disability Scale, SDS), were compared across diagnostic subgroups. Results. SP and OCD comorbidities were present in 30.4% of the sample, with subthreshold comorbidities present at twice the rate of threshold ones (22.6% vs. 11.3%). Compared with GAD patients, PD patients showed significantly higher subthreshold and threshold comorbidity rates (27.6% and 13.8% vs. 17.5% and 8.8%, respectively). Comorbid PD patients had higher SDS scores than the comorbid and non-comorbid GAD subjects. The presence of threshold SP comorbidity was associated with the highest SDS scores. Conclusions. SP and OCD comorbidities were found to be prevalent and disabling among GAD and PD patients, with higher subthreshold than threshold rates, and a negative impact on quality of life. Present findings stress the importance of a dimensional approach to anxiety disorders, the presence of threshold and subthreshold comorbidity being the rule rather than the exception.
