[Acute granulomatous appendicitis. (Contribution to preventive appendectomy in acute ileitis)].
Starting with one case of acute granulomatous appendicitis of their own observation, the authors review the scant literature on the subject (only 23 published cases to date) and advocate systematic appendicectomy in all isolated appendicular localizations of Crohn's disease. On the grounds that no post-appendicectomy fistulization has ever been reported in such patients, the authors recommend prophylactic appendicectomy also in the far more frequent cases of acute ileitis, to forestall the possibility of evolution into chronic Crohn's disease and the risk of missing a nongranulomatous acute appendicitis appearing with the same clinical symptoms.

[A-mode echography in surgery: a study of solitary thyroid nodules (author's transl)].
As part of their exploration of the possibilities afforded by A-mode ultrasonic investigation in several disorders of surgical interest, the authors report the results obtained in the study of solitary thyroid nodules. More precisely, after a brief explanation of ultrasonics, current apparatus for echography, and methods for echographic examination, they describe the semiological features exploited in A-mode echography: namely nodules with liquid content, mixed content, solid homogeneous content, and solid heterogeneous content. They conclude with considerations on the principles and indications of this diagnostic procedure in the light of their personal experience.

[A-mode echography in surgery. Study of nodular lesions of the breast].
In the context of researches for studying the possibilities of ultrasonic A-mode research for a diagnosis of thyroid, mamma and abdominal organs affections, in this first part the authors make known the results obtained studying nodulary lesions. After a short notice about ultra-sounds, echoscopic apparati and methods for echoscopic research, they outline the semeiologic characters for echoscopic A-mode diagnostic and they stop on echoscopic obtained pictures: liquid crops, nodulary images with homogeneus echostructure scarcely ecogena and nodulary images with not homogeneus echostructure highly ecogena. Then they ended with some considerations about the principles and the indications of this method, in the light of personal experience.

[Pulmonary blastoma. (Personal case)].
The authors give a detailed description of one case of pulmonary blastoma recently come to their observation. Then, after a review of pertinent literature, they discuss the more interesting aspects of this pulmonary pathology, namely its rarity, uncertain histogenesis, difficult diagnosis, and above all baffling prognosis. They conclude with an appeal for further contributions on this interesting subject, in the hope of understanding it better through the study of an adequate number of cases.

[A case of giant hamartochondroma of the lung].
The authors present a case of pulmonary hamartochondroma of exceptional size, of which they give a clinical descrition and explain the surgical treatment. Next, aloso in the light of recent literature on the subject, they review the possible causes of this disorder in terms of several histopathogenetic hypotheses, and they discuss problems of differential diagnosis as well as the histopathological aspects of this rare, benign tumor of the lung. They conclude that even though malignant transformation of hamartochondroma is exceptional, these tumors should always be removed surgically as soon as they are diagnosed or reasonably suspected.
Hamartoma↗
[The diaphragmatic relaxatio (author's transl)].
The Authors briefly describe two cases of diaphragmatic relaxatio that they have seen and studied; then they make a revision of the literature about this uncommon disease. They speak about embryogenesis of the diaphragm and about nosology, etiopathogenesis, frequency (ages and sex) and phatological anatomy of this disease. In conclusion the Authors discuss in detail signs and symptoms, diagnosis and surgical treatment of diaphragmatic relaxatio.

[Peripheral vascular trauma (author's transl)].
The authors review several existing classifications of traumatic events affecting the peripheral blood vessels; after discussing the symptoms of such events and diagnostic guidelines, they outline therapeutic approaches and emphasize above all the need for prompt surgery with the least possible delay after the injury. They review of cases of their own observation, and conclude by highlighting the basic concepts of modern surgery in this field of pathology.

[Current views concerning the etiopathogenesis of reflux esophagitis in children].
Esophagitis is caused by a gastro-esophageal reflux sometimes reflecting anatomical inadequacy of structures that secure the relationships between the cardia and the diaphragm, fundus of the stomach, and other surrounding viscera, but more often due to functional deficiency of lower esophageal sphincter (LES), this representing the main factor for maintenance of the mechanism of cardial continence. Manometric studies of intraluminal pressures in the esophagus have revealed the presence of a high-pressure segment in the distal esophagus, where a mean pressure of 12-13 mm Hg obtains over a length of 3 or 4 cm. In the first two weeks of extrauterine life the LES is between 0.5 and 1 cm long, with a pressure of 3 mm Hg; pressure values in the LES equal adult values at about one month of age, showing that neuromuscular control of the sphincter has been achieved. Gastro-esophageal reflux, however, is very common in the newborn and not enough by itself to cause peptic disease of the esophagus; this requires the concomitance of morphological defects of the esophageal mucosa and/or dynamic-functional disturbances. This, according to the authors, is why esophagitis actually occurs in only about 60% of patients with radiologically and pHmetrically demonstrated gastro-esophageal reflux.

[Clinical picture and diagnosis of reflux esophagitis in children].
Whereas a burning retrosternal pain irradiating upward is the main symptom of reflux esophagitis in the adult, this symptom is usually not extant in children. Rather, the child will show unaccountable vomiting, stunted growth, anemia of unknown etiology, and respiratory disturbances. The pathologic condition more often associated with reflux esophagitis is hypertrophic stenosis of the pylorus, which is in fact regarded as one of the causes of the esophageal disorder. Reflux esophagitis may lead to ulceration and hemorrhage, and may evolve into cicatricial retraction and esophageal stenosis, the latter sometimes quite tight. The condition is diagnosed in light of radiological examination and endoscopy. Whit older children, one may add the Bernstein test and pressure and pH readings. The paper concludes by pointing out the different diagnostic approach in the newborn and small baby on the one hand and in older children on the other.

[Current trends in the treatment of reflux esophagitis in childhood].
A problem of some complexity is the management of pathological gastro-esophageal reflux due to the presence of cardio-hiatal malformation, malposition of the cardia and gastric tuberosity, a congenitally short esophagus, and the like. Sometimes, however, there is no demonstrable morphological aleration and the condition, characterized by primitive hypotonia of the LES, goes under the name of infant chalasia of the esophagus. The general policy is to try first a conservative treatment consisting of dietary and postural measures and the administration of metoclopramide and d;ugs that protect the esophageal mucosa; this stage, however, should not be prolonged beyond 6 weeks. The presence of gastro-esophageal reflux associated with hiatal hernia; the presence of severe esophagitis or peptic stenosis of the esophagus and the persistence of symptoms after an adequate period of conservative therapy constitute as many indications for surgical correction. Good results can be obtained by restoring or strengthening the failing function of the LES, as is done quite successfully with funduplication after Nissen or with method of Belsey-Mark IV.

[Congenital stenosis of the esophagus (personal case and review)].
Starting from personal observation of a case of congenital stenosis of the oesophagus, the Authors proceed to a review of the scanty literature on the subject. After a discussion of the most outstanding aspects of differential diagnosis, the frequent necessity of histological verification, especially in adolescence and adult age, in order to obtain a correct understanding of the nature of the case, is stressed. On the basis of an essentially favourable prognosis, the Authors maintain that, where medical and dilating treatment is insufficient, surgery is indicated and evidence the straight-forward nature of the process of exeresis in stenosis of valvular type.
