The immunoprofile of interstitial Cajal cells within adenomyosis/endometriosis lesions.

Adenomyosis and endometriosis are lesions which have aroused the interest for the investigation of antibodies specific to the structures from the composition, but also for the cause behind the appearance of these lesions in completely different structures. The impact they have on fertility is not known entirely, for they are difficult to diagnose. Endometriosis causes infertility and it is a hard to treat lesion. The research performed in the last years has been focused on the so-called linkage analysis, or reverse genetics. It refers to identifying the genes which are prone to developing this affection. We investigated clinically 40 female inpatients (n=40) who had underwent genital surgery and received a variegate diagnosis in the "Sf. Ioan" Emergency Hospital, Bucharest, Romania, between January-September 2014 and also their histopathology and immunohistochemistry. We proceeded with the histopathology examination in order to establish a diagnosis in respect to the admission diagnosis and then, using the ABC (Avidin-Biotin complex) method, we analyzed the immunohistochemistry of the following markers: S100 protein (for detection of ganglia and nerve cells), CD117÷c-kit (selective detection of interstitial Cajal cells - ICC), desmin and vimentin (intermediary filaments for detecting ICC-like cells, which cohabit with uterine myocytes and are not contractile cells) and CD10 (a sensitive and useful immunomarker in the diagnosis of endometrial stroma and, in some cases, of neoplasia). Our study, regarding the immunoprofile of some markers of adenomyosis÷endometriosis lesions, supports the hypothesis that the interstitial Cajal cells are non-reactive, they are not in relationship with investigated lesions, but CD10 is a very useful marker to highlight the endometrial stroma in query cases.

Technological update of the video-endoscopic approach of the diagnosis and staging of tumors in children.

The pediatric patient is often difficult to diagnose, especially since the surgical pathology is tumoral. Establishing the histopathological diagnosis of a tumor, staging of a disease and certifying the existence of rare pediatric affections are three of the motives for which the specialists frequently appeal to an exploratory laparoscopy, accompanied by biopsy procedures. The paper presents the laparoscopic biopsy experience of the team from the Department of Pediatric Surgery, "Maria Sklodowska Curie" Emergency Clinical Hospital for Children, Bucharest, Romania. From 2000 to 2013, 95 such procedures were performed (7.76% of a total of 1224 laparoscopic interventions). In many cases, the laparoscopy had an exclusive diagnostic purpose, of whose success has been primarily responsible the targeted biopsy. Current issues are discussed, centered on the most advanced technologies used in minimally invasive approach of pediatric malignancies, referring to the effect of minimizing the possible complications that can arise from this type of intervention. The authors concluded that laparoscopic technique is the method of choice in comparison to other ways of biopsy (classical surgery, ultrasound guidance, tomography, etc.), and it is characterized by a high diagnostic value.

The impact of melanocytic cell destruction in pediatric facial burns and plastic surgery therapeutic management.

The main role of the melanin production belongs to the keratinocyte-Langerhans-melanocyte complex that within a burn injury might be destroyed. A particular aspect has the pediatric patient with burns due to a deficit in pigment synthesis and particularities involving the growth process of facial structures. This article presents four eloquent cases of pediatric patients with sequelae, consequence of facial burns that varied in depth and etiology. The age of patients at time of admission was between four and 18 years, and the interval between production of the primary lesion and admission was variable (0-17 years). Conservative treatments prove to be insufficient, requiring the destroyed structures to be replaced with compatible tissue by surgical intervention. The therapeutic success of skin grafts and dermal substituents acknowledges the main role of plastic surgery. New technologies as well as new cell focused studies support the clinical proven results as well as they enlarge the spectrum of potential available therapeutic methods in order to obtain the best therapeutic results.

Laparoscopic exploration in pediatric surgery emergencies.

The laparoscopic approach of pediatric surgery emergencies represents a specific preoccupation in hospitals everywhere in the world. Nowadays, when confronted with this pathology, pediatric surgeons are able to apply certain well-defined therapeutic protocols, depending on the technical equipment at their disposal and their laparoscopic expertise and training. We hereby present some of the surgical pediatric emergencies that have been subjected to minimally invasive celioscopic techniques, in the Department of Pediatric Surgery "Maria Sklodowska Curie" Hospital, from August 1999 to July 2007. Out of 83 exploratory laparoscopies, 12 were performed for emergency pathology, other than acute appendicitis (in its various forms, including peritonitis) or acute cholecystitis. However, during the above-mentioned period, the number of therapeutic laparoscopies for emergencies has grown significantly (239 from a total of 663 laparoscopies), reflecting to a large extent the activity of a clinic with an emergency surgery profile. The authors conclude that exploratory laparoscopies in pediatric surgery emergencies are suited for surgical teams with a solid experience in celioscopy and a certain professional maturity, necessary to correctly appreciate the surgical and anesthetic risks involved by each individual case. It is not recommended that inexperienced laparoscopic surgeons embark on the "adventure" of this minimally invasive approach for this type of pathology. Only when the training and learning process is fully and correctly completed, specialists are offered the advantage of continuing a celioscopic exploration by performing a minimally invasive therapeutic procedure, even for a pediatric emergency case.

Exploratory laparoscopy--diagnosis method in pediatric surgery pathology.

The purpose of this article is to establish the important place of laparoscopy in the diagnosis management of pediatric surgery pathology. In addition, it is intended to become a pleading, concerning the true and realistic benefit, for the pediatric patient, of minimally invasive surgery. In our country, the method was taken over from general surgery and had a few years of latency in imposing itself. We consider that each pediatric surgeon is required to have a mandatory period of training in this topic. This is the reason why we appeal to the young generations of pediatric surgeons but also to the surgeons with many years of experience in classical surgical techniques, who are able to perfect the diagnostic and treatment methods in many medical specialties. The clinical research took place in a retro and prospective manner from August 1999 to July 2007 in the Department of Pediatric Surgery "Maria Sklodowska Curie" Hospital and studied 663 laparoscopic surgeries. 83 of them were exploratory laparoscopies (39 boys and 44 girls) and the other 580 were therapeutic procedures with accurate pre-operatory diagnostics. The surgical activity of our department concerning exploratory laparoscopy was also appreciated due to the decisional and therapeutic algorithms that were conceived. The motivations for exploratory laparoscopic procedures are multiple and arise from many causes, from right lower quadrant pain syndrome and abdominal tumors to congenital malformations and non-palpable testis. The processed data revealed the utility of laparoscopy, concerning most of the pediatric surgical pathologies and in the same time allowing them to continue the exploratory method of diagnosis with a minimally invasive therapy. The discrepancy between the exploratory benefit (sometimes minor) and the surgical trauma of an open exploratory surgery, explains the utility of laparoscopy that took over most of open surgery indications.
