[Gastrointestinal human myiasis caused by Eristalis tenax].

The myiasis observed in Bariloche are characterized and the probable conditions under which the infestations took place established. The larvae obtained from faeces of 2 patients were identified as Eristalis tenax (Diptera: Syrphidae) according to Hartley (1961) and Organización Panamericana de la Salud keys (1962). These 2 cases of human gastrointestinal myiasis were the first to be registered in Bariloche (Patagonia, Argentina) and their characteristics were similar to those described for this species in other parts of the world. The lack of specific control measures in the domestic water supply system was the most probable cause of the infestation. This event extends the distribution of E. tenax and human gastrointestinal myiasis in South America to 41 degrees 03' S.

[Distant results of putting the feeding tube through wound after laryngectomy].

Authors present their own postoperative results in nourishing the patients after laryngectomy. Their several years' observations, based on the group of 318 patients, were connected with the risk of the postoperative complications. In proposed way of nourishing (introduced by B. Latkowski) the point is in putting the nutritive drain not through the nose, but directly through the cutting during laryngectomy. The main aim of the research was presenting good points of this method and existence of no complications with the most dangerous--fistulas.

[Pathological changes of frontal sinus in the materials of the Otolaryngological Clinic of Medical Academy in Lódź (1986-1996)].

Authors report 25 cases of frontal sinus diseases treated surgically at the ENT Department Medical University of Lodz. There were three groups of pathologies: 13 cases of inflammatory disease, 9 osteoma cases and 3 trauma cases. The total number of 30 surgical procedures has been performed (13 Beck's method, 6 radical method, 6 classical method, 2 Ogston-Luc method and 3 reconstructions of anterior wall of the frontal sinus using bone sutures). In each group the type of surgical method and the causes of the possible postoperative pitfalls and recurrence of the disease were analyzed.

[On keratomas on the frontal sinus].

Etiopathogenesis of the frontal sinus kertomas has been discussed paying a special attention to the frequency of its occurrence reported in literature. Authors present a rare complication of frontal sinus keratoma involving a bone destruction of nearby lying structures.

[Oxidase activity in patients with laryngeal carcinoma treated by radiotherapy].

According to Ravin's method an oxidative activity of ceruloplasmin was determined in the group of patients with carcinoma of larynx before and after rtg-therapy and at the control group of healthy individuals. As a result of this assay the significantly increased of oxidative activity ceruloplasmin was obtained in the individuals with the carcinoma of the larynx before rtg-therapy in comparison to the group of healthy subjects. Simultaneously a significant decrease of the oxidative activity of serum ceruloplasmin in the individuals with carcinoma of the larynx after rtg-therapy was observed.

Y chromosome microdeletions and male subfertility.

Men with azoospermia and severe oligozoospermia have been investigated by molecular probing of the long arm of the Y chromosome. We find microdeletions affecting various parts of the long arm of the Y chromosome in approximately 10% of men with non-obstructive azoospermia and severe oligozoospermia but not in a fertile comparison population. This work needs further confirmation in different countries and different racial groups but it would appear that microdeletions (and presumably genetic defects) are commonly associated with defects of spermatogenesis. These findings have implications for the management of severe male subfertility with in vitro fertilization/intracytoplasmic sperm injection.

[A rapid test for the analysis of lactase and sucrase activity in the jejunum (a comparative study)].

Jejunal lactase and sucrase activities were demonstrated in biopsy specimens obtained endoscopically using a rapid test which had been developed previously. The results were compared with enzyme activities determined by Dahlquist's method. The data suggest that the rapid test is suitable for the demonstration about the presence of lactase and sucrase, and the results are correlated with enzyme activities measured by assay. The main advantage of the test, that it is rapid, simple and cheap, no special equipments are necessary, so it can be used in every endoscopic department.

Measurement and demonstration of lactase and sucrase activities in jejunal mucosa.

Jejunal lactase and sucrase activities were demonstrated on endoscopically obtained biopsy specimens by a rapid test which had been developed earlier. The results were compared with enzyme activities found by Dahlquist's method. The data suggest that the rapid test is suitable for the semiquantitative determination of lactase and sucrase, and the results correlate with enzyme activities measured by the Dahlquist assay. The main advantage of the test is that it is rapid, simple, and cheap, and because no special equipment is necessary, it can be used in any endoscopic department.

[A simple isotope method for studying of gastric emptying of solid foods].

A simple isotope method is explained by the authors for noninvasive functional evaluation of the gastric emptying of solid meal. According to the results of in vitro measurements suitable solid phase labelling was provided by boiling the egg traced with injected Tc-99m-pertechnetate. The evaluation of gastric emptying by means of test meal containing the radiolabelled boiled egg is simple, inexpensive and the radiation hazard is minimal. In cases of intact stomach the gastric emptying of solids (T2 = 115.1 +/- 12.4 min) were significantly slower, than in cases of Billroth I (T2 : 66.7 +/- 6.9 min, p less than 0.01) and Billroth II (T2 = 28.8 +/- 3.3 min, p less than 0.001) resections. Similarly, there was a significant difference (p less than 0.001) between the mean half time values of the two operated groups.

Jejunoscopic lactose provocation.

A new method for testing lactose intolerance was developed. The examination is performed by jejunoscopy using lactose dilution for provocation and sucrose for control. Macroscopic and microscopic changes in the jejunal mucosa are examined after administration of solutions. The results of this study demonstrated that lactose administration causes prompt change in the jejunal mucosa in cases of lactose intolerance but had no effect in cases of lactose tolerance. Administration of sucrose did not result in any change. This method is effective in proving lactose intolerance and may be useful to elucidate the pathogenesis of this disorder.
