Metastatic Malignant Melanoma Causing Small Bowel Intussusception: A Case Report with 4-year Follow-up.

Primary mucosal malignant melanoma of the small bowel is extremely rare. The small bowel is mostly affected by metastases of the primary malignant melanoma of the skin. Bowel obstruction is a rare complication of metastatic melanoma. We present a case of small bowel obstruction in a 49-year-old man with history of skin malignant melanoma. A segmental resection of the ileum with termino-terminal anastomosis was performed. Pathohistological examination showed metastatic melanoma. After 4 years of follow-up, the patient is still free of the disease.

Anxiety, Depression and Personality Types in Patients with Inflammatory Bowel Disease: Comparisons with Peptic Ulcer and the General Population.

BACKGROUND: To explore corellation of anxiety, depression ant type of personality in inflammatory bowel disease (IBD) and compare with peptic ulcer (PU). SUBJECTS AND METHODS: In this study, prevalence of anxiety, depression and type of personality was investigated in 362 cases divided into three groups: 112 of IBD patients, 122 of peptic ulcer patients and 128 of control group who didn't have any gastrointestinal or psychic complaints. IBD and peptic ulcer diagnosis were established by standard diagnostic procedures (anamnesis, clinical manifestations, laboratory, endoscopy and biopsy in IBD and upper endoscopy in peptic ulcer). Anxiety and depression were established by Hamilton anxiety rating scale (HAM-A) and Hamilton rating test for depression (HAM-D). Type of A/B personality was established by Bortner scale and D type of personality by Denollet scale (DS14). RESULTS: Anxiety was found in 47 (41.9%) and depression in 44 (38.3%) of a total of 112 IBD cases. In group with peptic ulcer anxiety was found in 40 (32.8%) and depression aalso in 40 (32.8%) of total 122 cases. In control group anxiety was diagnosed in 21 (16.4%) and depression in 20 (15.6%) of total 128 cases. Anxiety and depresson were significantly higher in both groups than in control group but anxiety and depression were significantly higher in IBD group than peptic ulcer group. D type of personality was statistically significant in peptic ulcer group. CONCLUSION: Anxiety and depression in IBD and peptic ulcer cases have a greater prevalence compared to the normal population and surprisingly are higher in IBD than peptic ulcer group. D type of personality is associated with peptic ulcer.

Scrotal abscess as the first symptom of fatal necrotizing pancreatitis.

Acute necrotizing pancreatitis represents a severe form of acute pancreatitis, characterized by pancreatic collections and necrosis of the pancreas and surrounding tissues. It is associated with higher rates of morbidity and mortality. Scrotal swelling is a rare complication of acute necrotizing pancreatitis due to the extension of pancreatic necrotic masses involving the inguinal canal and scrotum. We report a case of scrotal swelling as the first sign of unrecognized severe necrotizing pancreatitis with a fatal outcome.

Prognostic value of vitamin D receptor and insulin-like growth factor receptor 1 expression in triple-negative breast cancer.

AIM: Triple-negative breast cancer (TNBC) is characterised by shorter overall survival and an early peak of distant recurrences with still no specific targeted treatment available. Vitamin D receptor (VDR) and insulin-like growth factor receptor 1 (IGFR) have recently been described as potential new targets for anticancer therapy, yet their roles in TNBCs are still to be explored. In this study we investigated VDR and IGFR expression in patients with TNBC and compared them with clinical and pathological parameters and survival to possibly demonstrate their prognostic and therapeutic relevance. METHODS: The study included 96 patients with TNBC. Clinical and pathological parameters were compared with the immunohistochemical expression of VDR and IGFR. RESULTS: Positive VDR immunostaining was present in 27% of tumours and inversely correlated with higher mitotic score, histological grade and higher proliferation index measured by Ki-67 and related to the increased overall survival (OS). Out of 96 patients with TNBC, 35.5% of tumours were IGFR positive and correlated with higher mitotic score and Ki-67, and strongly correlated with shorter disease-free survival (DFS). Patients with VDR-negative and IGF-positive tumours had significantly lower DFS and OS. CONCLUSION: Approximately one third of TNBCs express VDR and/or IGFR. Their expression is linked with the recurrence of the disease and survival, which make them possible targets for treatment and a prognostic tool for dividing TNBCs into more homogeneous subgroups.

Pain Intensity Scales Comparison in Patient with Abdominal Pain.

BACKGROUND: The aim of study was to explore efficiency of the pain rating scales on patients experiencing abdominal pain, determine correlation between the scales and their applicability to general population and determine the minimal clinical important difference in mm on the VAS as discriminatory for difference in pain intensity. SUBJECTS AND METHODS: The study was performed at the Emergency Department of the University Clinical Hospital of Mostar on patients with abdominal pain which started less than 24 hours before, excluding patients under 16 years old, uncooperative patients and those with altered state of consciousness. The sample data were collected from February to May 2010. Hundred patients completed the questionnaire. Two patients, admitted to the Abdominal Surgery Department, were excluded. The patients were asked to sign the informed consent form and assess the level of pain on three scales (VAS, NRS, VRS). RESULTS: The NRS showed a significant difference in assessing the pain intensity in the observed time. By lapse of time, the patients were reporting lower pain intensity (P=0.017). VAS and NRS had high correlation coefficient values, indicating strong correlation and credibility. The NRS showed strong results correlation (r=0.784; P<0.001). Inter-scale correlation was growing over time. Correlation between VAS and NRS was very strong, the strongest in the last measurement (r=0.950; P<0.001). The NRS correlation with VRS (r=0.430; P<0.001) was slightly better than with VAS (r=0.402; P<0.001). The NRS proved to be the most sensitive to changes in pain intensity (SRM=0.305), whereas the VRS showed extremely low responsiveness (SRM=0.185). CONCLUSION: Having proved as the most useful, reliable and efficient pain assessment instrument, the NRS is hereby recommended as method of pain objectification and determining changes in pain intensity.

Immunohystochemical Expression of Vitamin D Receptor in Development Stages of Colorectal Carcinoma.

BACKGROUND: Chemo preventive and antitumor role of vitamin D is manifested through genetic and non genetic ways with a powerful antproliferatory and proapopoptic effect, which is proven by numerous epidemiologic studies. The genetic activity of vitamin D is determined through vitamin D receptors (VDR), a member of stero-thyreoidal family of nuclear receptors, which with vitamin D form a cell nucleus complex responsible for the chemo preventive and antitumor effect. VDR in tissue cells is present in the cytoplasm and the nucleus and manifests its genetic activity after transfer from the cytoplasm to the nucleus. The mechanisms for the transport and genetic control of the transport of VDR from cytoplasm to the nucleus in not yet completely understood. SUBJECTS AND METHODS: By using immunohystochemistry we are evaluating the correlation of cytoplasmic and nuclear expression of VDR during different stages of colorectal carcinoma: normal colorectal mucosa, hyperplasic polyp, low grade adenoma (LGD), high grade adenoma (HGD) and colorectal cancer. RESULTS: Our results confirm that the nuclear VDR expression is strongest in normal colorectal mucosa and in hyper plastic polyps, is gradually weakened in low and high grade adenoma while it is extremely weak or absent in colorectal carcinoma. At the same time the expression of cytoplasm VDR is weakest in normal colorectal mucosa and hyper plastic polyps while it grows during the adenoma stage and is most expressed during colorectal carcinoma. CONCLUSION: We conclude that vitamin D has a strong chemo preventive and antitumor effect in normal colorectal mucosa and hyper plastic polyps, while its antitumor and chemopreventive effect is progressively weakened and ultimately absent in colorectal carcinoma.

Attitudes of Students of Medicine, University of Mostar According to Induced Abortion.

BACKGROUND: Aim of this study was to establish attitudes of medical students on induced abortion and connection of those attitudes with religiousness, length of their studies, sex and various circumstances of pregnancy. SUBJECTS AND METHODS: In total, 148 students of the first, second, fifth and sixth year of medical faculty participated in the research. The study was conducted at the Medical Faculty of the University in Mostar. While collecting the data, we used a survey taken over from literature. The data were tested with adequate statistical methods afterwards. RESULTS: 81.1% of students would perform an abortion under certain circumstances (χ2=57.189; P<0.001). Most students answered that they would perform an abortion in case that a fetus had malformations (χ2=3.892; P=0.49) or if the mother's life were endangered (χ2=47.676; P<0.001). By comparison of students' readiness to perform an abortion under various circumstances of pregnancy depending on length of medical education, statistically significant difference was proved in the following circumstances: rape (χ2=6.097; P=0.014) and if the pregnancy would endanger mother's mental health (χ2=4.488; P=0.034). Students with shorter medical education expressed more liberal attitudes in the above stated circumstances. By comparison of students' readiness to perform an abortion under various circumstances of pregnancy depending on religiousness statistically significant difference was proved in the following circumstances: in case of 'abortion on demand', no matter the reason (χ2=11.908; P=0.012), teenage pregnancy (χ2=33.308; P<0.001) and if the pregnancy would interfere with mother's career χ2=35.897; P<0.001). Unreligious students expressed more liberal attitudes. CONCLUSION: Influence of length of medical education and sex on attitudes on abortion was not proved statistically. Impact of religiousness on that attitude cannot be commented due to very small share of unreligious students in the sample.

Prevalence of amebiasis in inflammatory bowel disease in University Clinical Hospital Mostar.

AIM: To explore the prevalence of amebiasis in inflammatory bowel disease (IBD), Crohn's disease and ulcerative colitis, in patients in Clinical hospital Mostar (Bosnia and Herzegovina, region of Herzegovina). METHODS: In this study, Entamoeba histolytica/dispar prevalence was investigated in fresh faeces by native microscopy and immunochromatographic rapid assay "RIDA(®)QUICK Entamoeba test", in 119 cases of new found IBD patients, 84 of ulcerative colitis and 35 of Crohn's disease and in control group who had also 119 patients who didn't have any gastrointestinal complaints. IBD diagnosis was established by standard diagnostic procedures (anamnesis, clinical manifestations, laboratory, endoscopy and biopsy). RESULTS: Entamoeba histolytica/dispar were found in 19 (16.0 %) of a total of 119 cases, 12 (14.3 %) of the 84 patients with ulcerative colitis and 7 (20.0 %) of the 35 patients with Crohn's disease. As for the 119 patients in the control group who had not any gastrointestinal complaints, 2 (1.7 %) patients were found to have E. histolytica/dispar in their faeces. Amoeba prevalence in the patient group was determined to be significantly higher in group with Crohn's disease, ulcerative colitis and IBD total than in the control group (p < 0.001). CONCLUSION: Ameba infections in patients with Crohn's disease and ulcerative colitis, have a greater prevalence compared to the normal population.

The influence of dreinage in the treatment of chronic pilonidal sinus disease using midline closure.

Unsatisfactory postsurgical end results in the treatment of chronic pilonidal sinus disease caused by long term healing, pain, inconvenience and recurrences of the lesion still remain problem after various surgical techniques have been described and used. This study was designed to show results of several aspects of midline closure technique with respect for surgical complications, hospitalization length and recurrence. This study included 90 patients with pilonidal sinus treated by surgery with midline closure at the department of General surgery of Clinical Hospital Mostar between January 2004 and January 2009. The patients were divided in three groups considering the type of drainage used. Data collected retrospectively included demographics, positive diagnosis of chronic pilonidal sinus, operative technique, type of drainage, complications, hospital stay and recurrence of the disease. Mean hospital stay after excision and midline closure technique was 4.68 days Complication rate was 18/90 (20%). Infection occurred in 18 patients (20%), dehiscence occurred in 10 patients (11.1%). Mean recurrence rate during follow up period was 12/90 (13.3%); range, 24-84 months. There was no statistically significant difference among three groups in hospital stay length (p>0.05), in complication rate (χ(2)=1.66, p>0.05), nor in recurrence rate (χ(2)=1.91, p>0.05). Statistically significant difference was shown between complication rate among non drained and actively drained patients (χ(2)=1.11, p<0.05). Primary midline closure is not a satisfactory method in the treatment of chronic pilonidal sinus, especially without drainage, leading to numerous complications and high rate of recurrence.

Rupture of splenic artery aneurysm in primipara five days after cesarean section: case report and review of the literature.

Splenic artery aneurysm (SAA) is a rare and usually asymptomatic vascular anomaly which carries the risk of rupture and fatal hemorrhage. It is more common in women and is usually associated with pregnancy. We present the case of rupture of SAA, 5 days after giving birth by cesarean section, which was diagnosed with Multi-Slice Computed Tomografy (MSCT) angiography and was successfully operated in the second emergency laparotomy, with the final good outcome for the mother. This case indicates that in case of sudden bleeding in the abdomen, with the development of hypovolemic shock, especially in the peripartum period, should be suspected rupture of SAA. The paper presents a critical review of this case, with a review of the literature.

Primary large-cell neuroendocrine carcinoma of the scrotum.

Neuroendocrine tumors (NETs) mostly develop from the neural crest cells but a few arise from neuroectoderm. They are common in the lungs and gastrointestinal tract but rare in the genitourinary tract. A 78-year-old man with no family history of malignant or hereditary diseases presented with a 3-month history of a rapidly growing asymptomatic scrotal nodule and swelling in the groin. He had a negative history of sexually transmitted disease and of trauma, fungal infection or chronic irritation in the scrotal area; there was no history of radiotherapy or exposure to chemicals or arsenic. Both the scrotal and groin lesions were excised with a minimum of 1.2 cm of normal skin. Examination of the specimen revealed a confined poorly differentiated large-cell neuroendocrine carcinoma with a metastasis to the inguinal lymph nodes. Three months after the excision we found a local recurrence. The recurrent tumor revealed tumor tissue concurrent with the primary lesion. To the best of our knowledge, there have been no previously published case reports on neuroendocrine tumor of the scrotum.

A randomised two-way comparison of mastectomy performed using harmonic scalpel or monopolar diathermy.

The purpose of this study was to perform an overall evaluation and comparison of the success rate of modified radical mastectomy by harmonic scalpel and monopolar electrocauter The prospective study included all of the patients that were planned for and mastectiomized because of breast carcinoma during July 1st 2008 until December 21st 2008 at the Department of Surgery and Urology, University Hospital Mostar. Duration of the surgical procedure, intraoperative blood loss and operational drain secretion was measured and registered. Leukocyte number (Le), interleukin 6 (IL-6), C-reactive protein (CRP) and erythrocyte sedimentation rate was tested and registered out of peripheral venous blood before the operation, 4 hrs after it, as well as on the first, second and third day after the operation. Every patient was tested for postoperative pain intensity, amount of administered analgesics during hospital stay, number and types of postoperative complications; also the time needed for return to everyday activities was registered. 61 patients were included in the study. 31 patients were operated with the harmonic scalpel, and 30 of them with the monopolar electrocauter. There is no statistically significant difference between the operation time in the two groups: 78.50 +/- 17.50 minutes by harmonic scalpel and 82.50 +/- 18.50 minutes by electrocauter (p = 0.796). The smaller amount of intraoperative blood loss is statistically significant in the group of patients mastectomized by harmonic scalpel 78 +/- 31 ml compared to 256 +/- 112 ml in the group mastectomized by electrocauter (p < 0.001); as is the total operational drain secretion: patients mastectomized by harmonic scalpel 540 +/- 390 mL compared to 960 +/- 710 mL in patients mastectomized by electrocauter (p < 0.001). There is no statistical difference in the number of leukocytes in blood after modified radical mastectomy using the harmonic scalpel or electrocauter (p = 0.957), or in erythrocyte sedimentation rate (p = 0.114), CRP (p = 0.071) and IL-6 (p = 0.082). The duration of postoperative hospital stay does not differ statistically between the two groups, nor does the postoperative pain intensity, amount of administered analgesics, number or types of postoperative complications, as well as the time needed for return to everyday activities. Therefore using the ultrasound harmonic scalpel in comparison to monopolar electrocauter brings certain advantages, which however do not contribute significantly to the total success rate of the operation.

Comparison of results of surgical treatments of primary inguinal hernia with flat polypropylene mesh and three-dimensional prolene (Phs) mesh--one year follow up.

The aim of this study was to compare the results of the surgery of inguinal hernias using flat polypropylene mesh and three-dimensional prolene (PHS) mesh. The study included two groups of 40 male patients, aged 18-50 years, with the diagnosis of inguinal hernia. One group was operated with a flat polypropylene mesh, while the second group was operated with three-dimensional prolene (PHS) mesh. The study has shown that the operation with three-dimensional prolene mesh lasted 15 minutes longer and that the patients had stronger inflammatory response. Statistically, there was no significant difference in post-operative pain intensity, post-operative use of analgesics, length of hospitalization, return to daily activities, early and late post-operative complications. No recurrence was registered in any of the groups. The analysis of results indicates that there is no difference in treatment of inguinal hernia with flat polypropylene and three-dimensional prolene (PHS) mesh.

The relation between the serum calcium level and the complication incidence in haemodialysis uremic patients.

The mineral metabolism disorder is the most influential factor of the morbidity and mortality incidence of haemodialysis uremic patients. The second most influential factor is the infection, which is the most frequent complication with an undesirable outcome. In recent times, the relation of the increased serum calcium and phosphorus level on the one hand, and the morbidity and mortality of that population in case on the other, has been observed. However, insufficient professional and scientific thought has been given to the relation of the lower serum levels of the aforementioned minerals and the morbidity and mortality incidence. We have researched the relation between lower serum calcium level (hypocalcaemia) and the complication incidence, especially infection. Throughout the time period of 18 months, 120 haemodialysis uremic patients were observed and 76 (63.3%) of them had serum calcium level below the lower threshold of referent values (9.0-9.5 mg/dL). In the patients with a lower serum calcium level (hypocalcaemia) a significant infection incidence (chi2 = 3.99; p = 0.0468), a significant sepses incidence (chi2 = 8.016; p = 0.04), a significant total complication incidence (p < 0.05) were determined, as well as a higher vascular access local infection incidence, but without statistically significant research results of this relation (chi2 = 0.098; p = 0.7598). We are of the belief that the incidence of the vascular access local infection should be examined on a greater number of patients; therefore, the significance of the examined relation in such an instance would be expected. The total infection incidence in all 120 observed patients is 3.8 for 100 months. It is to be concluded that the research findings indicate the association regarding the appearance of low serum calcium concentration (hypocalcaemia) and an increased complication incidence, especially the inflammation that leads to the requirement of further research in order to decrease morbidity, and consequently also the mortality of the observed population of patients by means of programmed therapy approach.
