Our experience in the surgery of otosclerosis

A retrospective study of 613 operations on 495 patients with otosclerosis was made in the Department of Otorhinolaryngology of Hospital General Universitario of Alicante between 1974 to 1992. The clinical-pathological characteristics of this series were studied. Statistical analysis of the results was made. The improvement in air-bone gap for conversational frequencies was 27 dB. Closure of the postoperative air-bone gap for conversational frequencies was 7.6 dB and the overall percentage of closure of this gap was 80.5%. Better auditory results were obtained with partial platinectomy than with stapedectomy. Nothing was inserted between the prosthesis and the vestibule, permitting a shorter, easier operation with no occurrence of perilympathic fistule.     

Video laparoscopic surgery and rectal prolapse. Our experience in rectopexy

BACKGROUND: Laparoscopy is gaining an important role in the treatment of benign colorectal disorders. The aim of this study is the evaluation of clinical and functional results in 4 patients submitted to a laparoscopy rectopexy according to Wells. METHODS: Four females (22-76, mean 53.7 years) affected from a total rectal prolapse with fecal incontinence underwent this procedure from 1993 through 1995. Six months after surgery, at the end of a rehabilitation program consisting of kinesitherapy, bio-feedback and electrostimulations, all patients have been re-evaluated by means of a clinical exam, anorectal manometry, defecography. RESULTS AND CONCLUSIONS: Preliminary results seem satisfactory and may allow to prefer this approach instead of the traditional open one.     

Our experience with lymphadenectomy in gastric cancer surgery

The Authors in this work study a comparison between 27 patients who underwent total gastrectomy with "regional" lymphadenectomy for gastric cancer during the period 1986-1991 (Group A), and 27 patients who underwent total or sub-total gastrectomy associated to D2 or D3 lymphadenectomy (Group B) according to the rules of the Japanese School (localization of the neoplasia and node involvement). No statistically relevant differences were shown in the overall long term survival, although in the group B there were both an high number of patients with stage III neoplasia and more invasive carcinomas. Extended lymphadenectomies, regional and D2 or D3, gave good results as far as long term survival was concerned in early stage cancers, but the same success was not achieved in advanced cancers especially in stage III. In order to improve the survival in advanced neoplasias since one year a D4 lymphadenectomy is performed in T2 or T3 and/or N2+ cases.     

Computerized digital thermometry in acrosyndromes. Personal experience

A diminution of the cutaneous temperature of the fingers and the latter's delayed recovery are constant features in the symptomatological triad of Raynaud's disease (RD). Thermometry is a method which can provide an objective evaluation of this phenomenon. The authors aimed to verify the value of thermometry using a computerised digital thermometer to measure basal temperature, that during cooling to 10 C, and the response. A computerised system with an AVTR interface was utilized using different probes for the 10 fingers and measuring temperature minute by minute up to 25 degrees. A total of 51 subjects were examined: 19 were asymptomatic for acrolocalised pathologies and 32 were symptomatic. No close correlation was observed between clinical and instrumental data. In fact 31.5% of the asymptomatic subjects had a "non-normal" reaction to the test; on the other hand, in the group of female over-50-years-old with symptoms suggesting RD, 44.4% of cases revealed normal instrumental patterns. Therefore no discriminating parameters were identified which might have allowed the instrumental identification of subjects suffering from RD compared to healthy individuals: there was a good level of sensitivity but scarce specificity.     

Computerized digital thermometry in Raynaud's disease. Personal experience

BACKGROUND: Computerized digital thermometry has been used for instrumental diagnosis of Raynaud's disease, that is characterized by diminution of the cutaneous temperature of the fingers and the late delayed recovery. Thermometry permits to measure basal temperature of the ten fingers, during cooling to 10 degrees C ("cold test") and the response, measuring temperature minute by minute up to 25 degrees. METHODS: In order to assess vasospastic ischemic disease a total of 66 subjects have been examined: 19 were asymptomatic for acrolocalised pathologies (control subjects) and 47 were symptomatic. RESULTS: No close correlation was observed between clinic and instrumental data. In fact 31.5% of the asymptomatic subjects had a "non-normal" reaction to the test; on the other hand, in the group of female over-50-years-old with symptoms suggesting Raynaud's disease, 38.5% of cases revealed "normal" instrumental patterns. Therefore no discriminating parameters were identified which might have allowed the instrumental identification of subjects suffering from Raynaud's disease compared to healthy individuals. CONCLUSIONS: In conclusion, computerised digital thermometry is a technique with a good level of sensitivity, while the specificity is scarce.     

Cutaneous mechanical staplers. Our experience

This paper reports the results of a trial, comparing the use of disposable skin staplers with conventional nylon or silk sutures in skin closure. This study began in 1986; 7274 patients undergoing elective and emergency operations were controlled during the postoperative period, 3 and 6 months after surgery. It was shown that skin clips instead of sutures decrease the operative time, produce wound healing with a good cosmetic results, and above all a significant lowering of the wound infection rate.     

Reversal of Hartmann's procedure. Our experience

Hartmann's procedure has progressively changed its indications in the last years; nowadays they are reduced by the increasing of anesthesiology and the introduction of stapler devices. The introduction of staplers makes reconstructive operation easier and it contributes to a sensible increasing of reversal percentage after Hartmann's procedure. Video-assisted techniques make Hartmann's procedure possible for older patients with high-risk of post-operative general complications. The authors describe the results obtained with traditional and video-assisted reversal Hartmann's procedure, comparing with data from Literature.     

Rubber band ligation of hemorrhoids. Our experience

The authors present their series of rubber band ligation of hemorrhoids performed from 1991 to 1994 in the Unità di Colon Proctologia of Modena, that is located in the Second Division of Surgery of the Surgical Department of Modena University. In that period 158 patients were treated. Age range was between 17 and 93 years old, and patients were affected by II and III degree of hemorrhoids. The complications verified were: 14 cases of recurrence (8.8%), 2 cases of severe bleeding, no case of perineal sepsis or urinary retention. Other complications of less importance were 89 cases of pain (56.3%), not severe bleeding in 23.41% of patients. Results show that this method of treatment of hemorrhoids, used by experts, is the first choice treatment of this pathology.     

Our experience with silicone in rhinomentoplasty

Twelve young (mean age 23 years, range 18-28) and 12 elderly (mean age 76 years, range 65-89) volunteers were given a single oral dose of 80 mg valsartan after an overnight fast. Each group consisted of six male and six female subjects. Mean systemic exposure to valsartan was higher in the elderly when compared with the young (AUC(0-24 h), 52% increase and AUC(0-infinity), 70% increase). Variability, as shown by the coefficient of variation (CV), was larger for the elderly subjects and ANOVA of the log transformed AUC showed a significant difference between the two groups. This difference was largely brought about by five elderly subjects (one male, four females), whose AUC was about 2-fold higher than the rest of the group. For the remaining elderly subjects, plasma valsartan AUC was similar to that observed for the young volunteers. This higher systemic exposure in five of the elderly subjects is not thought to be of clinical relevance when data from the patient population are considered. Other covariates--such as body weight, comedication, creatinine clearance, valsartan kinetics (absorption rate, distribution, and elimination)--did not explain the higher AUC in this subset of the elderly group. Data from the present study were compared with population kinetic data obtained from larger clinical trials including hypertensive patients in all age groups. Using this population approach, there was no difference in the pharmacokinetics of valsartan between male and female patients. Also, a relationship between plasma clearance of valsartan and age was established. The median age of patients in the hypertensive pool was 55 years. For an average 70-year-old patient, plasma clearance of valsartan is predicted to fall by 22% compared with an average 55-year-old. For the population this difference is not sufficient to warrant initial dose adjustment based on age per se. The covariate age, does not completely explain the variability in the pharmacokinetics of valsartan within the general population. The treatment was well tolerated.     

Urethral diverticula in the male. Our experience over 10 years

Following mobilising chemotherapy and myeloid growth factors, some heavily pretreated patients do not mobilise adequate numbers of peripheral blood progenitor cells (PBPC). It would be clinically useful to identify such patients in advance. A recent scoring system based on previous therapy may be useful in predicting CD34-positive cell yield. In this study we validated this scoring system on an independent group of 99 patients undergoing 103 harvesting episodes. In 61 patients mobilised with cyclophosphamide 1.5 g/m2 and G-CSF, those with treatment scores less than 21 yielded significantly more CD34-positive cells than patients with scores greater than 63 (P = 0.0012). Previous treatment with melphalan or carmustine was associated with a significantly lower yield of CD34-positive cells (P= 0.0001). No relationship was seen between the time from previous chemoradiotherapy and harvest outcome. Patients with treatment scores less than 21 required a shorter duration of G-CSF therapy (P = 0.05). Similar findings were seen in 42 further mobilisation cycles undertaken with alternative mobilisation schedules. The present data suggest that a score summarising previous treatment can be used to predict CD34 yields, and could be of clinical use to identify poor PBPC mobilisers in advance.     

Aplastic anemia in acute viral hepatitis type A. Our experience

Tropical pyomyositis is an infection of large muscle groups that can lead to sepsis and death. The most common etiologic agent is Staphylococcus aureus. It usually occurs in patients living in the tropics but is seen with increasing frequency in temperate climates, particularly in immunosuppressed patients, where it may be misdiagnosed and may cause severe morbidity and mortality. Diagnosis is based on the examination of pus from a muscle aspirate and treatment consists of surgical incision, drainage and appropriate antibiotic therapy. It is stressed to take into account pyomyositis in the differential diagnosis of immunocompromised patients with "cryptic" myalgia.
