Prosthetic mesh for infected abdominal wall defects? Report of a patient with a large full thickness abdominal wall defect and colostomy due to a gunshot wound.

Reconstruction of large, infected abdominal wall defects is often difficult. Local factors, such as defect size, presence of infection, adequate skin coverage and presence of enteric fistulae dictate the reconstructive method that can be used. Placement of prosthetic mesh materials into infected defects was generally not recommended due to a high rate of extrusion and fistulae.

[Secondary breast bilateral reconstruction with myocutaneous pedicled latissimus dorsi flap after primary bilateral skin sparing mastectomy reconstruction with consecutive severe capsular contraction].

We present a patient who was operated due to bilateral breast carcinoma with immediate bilateral breast reconstruction with silicone implants after skin sparing mastectomy in a neighbouring country to Croatia. One year following the operation a severe bilateral capsular contracture was manifested. Due to a large umbilical hernia and lower laparotomy scar it was not possible to reconstruct the breasts with any abdominal free or pedicled flap.

The supply of blood in the skin territory above the lower part of the serratus anterior muscle.

At present, the putative clinical use of the musculocutaneous and ostomusculocutaneous serratus anterior flaps has been compromised by the risk of partial or total necrosis of the skin overlying the lower part of the serratus anterior muscle. Therefore, the aim of this study was to delineate a skin area vascularized by perforant musculocutaneous branches of arteries stemming from the lower segment of the anterior serrated muscle. Black ink was injected in thoracodorsal artery branches for the serratus anterior muscle in 50 human cadavers before the autopsies (the study was approved by the Institutional Review Board).

Expression of c-myc, erbB-2, p53 and nm23-H1 gene product in benign and malignant breast lesions: coexpression and correlation with clinicopathologic parameters.

The aims of this study were to assess the expression of protein products of c-myc, erbB-2, p53 and nm23-H1 gene in benign and malignant breast lesions, to estimate their possible coexpression and to correlate the results of immunohistochemical analysis with various clinicopathologic parameters. The method used was the immunohistochemical detection of the corresponding protein. Expression of c-myc protein was high in both malignant and benign lesions (95% and 100%).

Primary malignant melanoma of the stomach.

We report a 54-year-old patient with a complaint of weakness, abdominal pain and weight loss. During the clinical examination a palpable tumor resistance in the abdomen was found as well as iron deficiency anemia. Gastroscopy showed an exulcerated, dark brown, fungiform tumor about 4 cm in diameter at the great curve of stomach.

Pseudoaneurysms of the brachial artery following venipuncture in infants.

Pediatric vascular injuries are increasing in frequency and represent a challenging problem in pediatric surgical practice. Increased survival of low birth weight infants and advances in invasive diagnostic procedures have resulted in a dramatic increase in the number of these injuries. Formation of pseudoaneurysm of the brachial artery in infants is a very rare complication of venipuncture, with only two cases reported in the literature.

Expression of cyclooxygenase-2 in fine-needle aspirates from breast carcinoma and benign breast diseases.

Numerous studies have demonstrated that the levels of cyclooxygenase (COX), the enzyme that catalyzes the conversion of arachidonic acid to prostaglandin H(2), and of prostaglandins are higher in various tumors and cells during inflammation than in normal tissues. The aim of the present study was to analyze whether COX-2 isoform expression was noticeably higher in fine-needle aspirates (FNA) from breast carcinoma than in FNA from fibroadenoma and fibrocystic breast tissue. COX-2 expression was detected by immunocytochemical (IC) staining and was analyzed by microscopic scoring and computer gray-scale analysis.

Nm23 gene product expression in invasive breast cancer--immunohistochemical analysis and clinicopathological correlation.

The nm23 gene/protein is a putative metastatic suppressor identified a decade ago in a melanoma cell line. A number of laboratory, clinical and pathological studies have been carried out to define its real biological and biochemical function as a step in a complex metastatic process. In our study we examined the significance of nm23 expression in 164 breast cancer patients, aged 35 to 74 years, in comparison to other parameters such as age, menopausal status, histological grade, tumor size, lymph node status, and hormone receptor status.

Early diagnosis and treatment of ectopic pregnancy.

During the period from 1995 to 1999, 64 patients were treated for ectopic pregnancy. All patients admitted to the department passed the same procedure including (complete preoperative laboratory findings, Beta HCG, serum progesterone and transvaginal colour Doppler). In patients who had ultrasound finding typical for ectopic pregnancy in combination with positive Beta HCG, conservative treatment was primarily done.

Metronidazole in the treatment of chronic radiation proctitis: clinical trial.

Aim: To evaluate the effectiveness of metronidazole in combination with corticosteroids in enema and mesalazine (5-aminosalicylic acid) in comparison with the same protocol without metronidazole in the treatment of chronic radiation proctitis.

Methods: Sixty patients with rectal bleeding and diarrhea were randomly divided into two groups. Patients in the first group were treated with metronidazole (3x400 mg orally per day), mesalazine (3x1 g orally per day), and betamethasone enema (once a day during 4 weeks).

Increased activity of nm23-H1 gene in squamous cell carcinoma of the head and neck is associated with advanced disease and poor prognosis.

The present study was undertaken to determine whether the nm23-H1 gene is expressed in squamous cell carcinoma of the head and neck (SCCHN) and whether the level of nm23-H1 protein or mRNA in cells vary as they progress to a more malignant phenotype. Of the 120 SCCHN studied 54 (45%) stained positively for nm23-H1 protein. Protein expression was significantly higher in more advanced stages of disease.

Surname as 'cancer risk' in extreme isolates: example from the island of Lastovo, Croatia.

The aim of this study was to analyze whether there are surnames which appear more frequently among the ancestors of cancer cases in a small isolate, in comparison to the ancestral surnames of the healthy controls, using the classic case-control design. The chosen setting was the island of Lastovo, Croatia, located more than 100 kilometers from the nearest coastal region. The period of study was 1970-1995, during which a total of 76 cancer cases were recorded in a population of approximately 800.

[Current use of bisphosphonates in clinical oncology].

Bisphosphonates represent nowadays a standard therapy of tumor induced hypercalcemia and are progressively more used in the treatment of tumor bone metastatic disease. Among several bisphosphonates, pamidronate is one of the most commonly used in clinical practice, so we also used it in succesful treatment of patients with breast cancer bone metastases. It has been shown that pamidronate reduces the frequency of hypercalcemia, bone pain and pathological fractures, although the mechanisms by which these effects are achieved are not completely clarified.

[Hormonal therapy with aromatase inhibitor in advanced breast cancer].

We investigated the aminogluthetimide therapy effect on 30 postmenopausal women with advanced breast cancer previously treated with tamoxifen as a first-line hormonal treatment. Aminogluthetimide exhibits anticancer effect by inhibition of aromatase enzyme which plays a key role in the conversion of androgen to estrogen in peripheral adipose tissue. This pathway presents the main source of estrogen in postmenopausal women.

One-stage reconstruction of war wounds with free osteocutaneous flaps.

Thirty-one patients with traumatic osteocutaneous defects of the extremities sustained during the war in Croatia and Bosnia and Herzegovina were treated at the Institute of Plastic-Reconstructive and Breast Surgery in Zagreb. Injuries were categorised using the Mangled Extremity Syndrome Index (MESI). The average length of bone defect was 5.

The management of war wounds to the extremities.

We present our experience in the treatment of war wounds in 174 patients treated in the Institute of Plastic and Reconstructive Surgery, Department of Surgery, Clinical Hospital Center in Zagreb. The wounds were divided into four categories depending on the type of injury and the extension of the soft tissue defect which showed the differences in primary excision and reconstruction of wounds. Patients were placed in one of two groups depending on their primary treatment and time of definitive reconstruction.

[Surgical management of war injuries involving soft tissue defects].

In this article, the authors emphasize that the knowledge of terminal ballistics is important for understanding of the pathophysiology of war wounds. They present their own experiences in the treatment of war wounds in 126 casualties, treated in the Institute of Plastic and Reconstructive Surgery, Department of Surgery, Clinical Hospital Center, Zagreb. About 96% of the wounded sustained extremity injuries, while head, neck and thoracoabdominal injuries appeared in a significantly smaller number of cases.

High-energy war wounds: flap reconstruction.

In this article, we emphasize that knowledge of terminal ballistics is essential for understanding the pathophysiology of war wounds. We present our own experiences in treatment of high-energy war wounds in 75 patients treated in the Institute of Plastic and Reconstructive Surgery, Department of Surgery, Clinical Hospital Center in Zagreb. Patients were divided into three groups with regard to the time of definite reconstruction, using local or free microvascular flaps.

[Microdochectomy with perioperative dye localization of ducts in patients with nipple secretion].

A series of 1321 women having a discharge from the nipple were examined at the outpatient clinic. Of seven basic types of discharge: milky, multicolored, purulent, watery, yellow (serous), serosanguineous and bloody, only the last four represent and indication for surgery. Galactography was performed in 55 patients as a necessary element in the surgical plan of management.

[Developmental and involutional breast disorders].

The majority of benign breast disorders may be classified as developmental and involutive. Mastalgia and breast nodularity represent the greatest groups of these disorders, while epithelial hyperplasia is a complex benign disorder which is most difficult to be evaluated. Sixty women with diagnosis of cyclic mastalgia and 30 with noncyclic breast pain were followed-up.

[An anatomic study of the septofascial layer in the forearm].

In the anatomical investigation the authors dissected 20 fresh cadaveric forearms to study septofascial layers. It's vascularization was based on radial artery and concomitant veins. We perfused those flaps with methylene blue in the proximal part of radial artery.
