Colorectal adenocarcinoma presenting with a pathological fracture due to a solitary bone metastasis to the tibia: a case report and literature review.

Introduction: Solitary bone metastasis of colorectal carcinoma (CRC) without other metastasis sites is extremely rare and can be found in less than 1% of patients with CRC. Aim: In the present study, we report the first case of a solitary tibia metastasis and its pathologic fracture as the first presenting feature of a colorectal adenocarcinoma. Material and methods: A 78-year-old female patient presented to our emergency department due to atraumatic pretibial swelling. Plain radiography did not detect any pathology. The swelling was incised and serous-bloody collection was evacuated, and the patient was discharged. On the 17th postoperative day, during a regular walk, the patient fell down and broke her leg, which transpired to be a pathologic fracture of the proximal tibial diaphysis, confirmed by X-ray. A biopsy of the altered bone tissue from the fracture site revealed metastatic colorectal adenocarcinoma. On colonoscopy, a circular mass in the upper rectum was found. Conclusions: Solitary bone metastases are most commonly found in bones that are related to venous drainage via the paravertebral plexus of Batson - the pelvis, vertebrae, and sacrum. Long bones are extremely rare localizations of solitary CRC metastases, with only few cases published so far in medical literature. In our case, the patient`s first symptom was related to the osseous tibial metastasis - leg swelling. No tumour was suspected until the pathologic fracture occurred. It is important to consider osseous metastasis in every patient with unexplained swelling, haematoma, or pain of the extremities and make a bone scan to recognize the metastasis early.

Urethral pressure profile before radical prostatectomy as a predictor of early postoperative continence.

OBJECTIVE: Urinary incontinence (UI) is one of the most common complications of radical prostatectomy (RP). Impaired urethral sphincter function is generally considered to be the most important contributing factor for UI; however, the mechanism of onset and recovery of urinary continence has not been fully elucidated. The objective of this research was to evaluate preoperative functional urethral length (FUL) and maximum urethral closure pressure (MUCP) as early continence recovery predictors after open retropubic RP (ORRP). METHODS: The research was conducted on a group of 43 patients with localized prostate cancer (PCa) in the period from July 2019 to May 2021. The urodynamic method of urethral pressure profile (UPP) was used to assess FUL and MUCP, and correlate with the postprostatectomy continence recovery. The severity of UI and bothersome were assessed using fully validated International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form (ICIQ-UI SF) and number of pads used in 24 h. Patients were interviewed about the use of urinary pads and asked to fill out the ICIQ-UI SF before and 2, 8, 16 and 24 weeks after ORRP. RESULTS: The median value of FUL (mm) and MUCP (cmH2O) was 69 (28-94) and 76 (16-223), respectively. Correlation and linear regression showed a statistically significant negative correlation between preoperative values of FUL and MUCP with ICIQ symptom score and the number of pads used per day at the four observed time intervals (p < 0.05). Such a result showed that patients with higher preoperative FUL and MUCP values were more likely to recover urinary continence earlier. A value of 65 mm for FUL and 80 cmH2 O for MUCP proved to be the cut-off values for continence recovery in 24 weeks after ORRP. CONCLUSION: Preoperatively evaluated FUL and MUCP seem to be valuable prognostic factors for early continence recovery after ORRP. Further investigation on a larger patient cohort is needed to evaluate the role of UPP in the preoperative management of patients with PCa.

PELVIC REHABILITATION FOR URINARY INCONTINENCE AFTER RADICAL PROSTATECTOMY.

Radical prostatectomy (RP) performed by open, laparoscopic, or robotic approach is considered the gold standard for localized prostate cancer (PCa). However, it carries the risk of postprostatectomy urinary incontinence (UI) and erectile dysfunction (ED) which significantly reduce patients' satisfaction with surgery and quality of life (QoL), therefore it is important to decrease the possibility or severity of these complications to a minimum. There are several preoperative prognostic factors such as urethral length and closing pressure obtained by magnetic resonance imaging and profilometry, as well as several variations in the surgical approach such as preservation of the neurovascular bundle (NVB) and puboprostatic ligaments, sparing or reconstruction of bladder neck, Retzius-sparing approach, and meticulous surgical dissection, used to predict or prevent unwanted side effects of RP. In addition, there are postoperative methods that can help reduce complications. In this review, we will present the role of pelvic rehabilitation with an emphasis on pelvic floor muscle training (PFMT) in reducing consequences of radical surgery.

Jejunal Lipoma Causing Intussusception in an Adult.

First described by Barbette in 1674, intestinal intussusception represents a telescoping of proximal bowel segment into the lumen of the adjacent aboral segment. Adult intussusception comprises only about 5% of all intussusceptions. We present a case of 28-year male patient who complained of colicky, intermittent epigastric pain for the last one month. Imaging detected specific signs of intussusception. Laparotomy revealed enteric intussusception of the jejunum caused by an intraluminal tumour, confirmed to be a benign lipoma on histology. Small bowel obstruction caused by jejunal lipoma in adults is a rare clinical entity and must be kept in mind when evaluating adult patients with abdominal pain. Key Words: Intussusception, Lipoma, Ileus, Jejunum.

Sexual Dysfunction in Patients with Epilepsy.

BACKGROUND: Patients with epilepsy commonly report sexual dysfunction (SD) and reproductive difficulties. This study aimed to evaluate the relationship between epilepsy, antiepileptic drugs (AEDs) and SD, and its association with the quality of life and depressive symptoms. SUBJECTS AND METHODS: This was a prospective study carried out in a tertiary healthcare centre. SD was evaluated using the internationally acclaimed questionnaire Arizona Sexual Experiences Scale (ASEX) that was successfully translated into Croatian and validated for this purpose. Depressive symptoms and quality of life were evaluated using the Hamilton Rating Scale for Depression (HAM-D17) and Quality of life in epilepsy-31 inventory (QOLIE-31). RESULTS: Of 108 patients (68 (63 %) women, 40 (37 %) men, mean age 39.54±15.91 (range18-80) years) with epilepsy, 16 (14.8%) had focal, 38 (35.2%) generalized and 44 (40.7%) both types of epilepsy. Mean overall total score on the ASEX questionnaire was 11.94±5.61 (mean total score women 12.85±6.00, mean total score men 10.4±4.55), with 48 reporting that they had sexual activity in the past week. Nine (8.33%) patients (7 (6.48%) women, 2 (1.85%) men, mean age 47.66±19.33 (range 25-80) years) had a score 19 and above, 38 (35.18%) patients (27 (25%) women, 9 (8.33%) men, mean age 46.82±17.78 (range 19-80) years) individual score 5 and above on any one item, and 33 (30.55%) patients (26 (24.07%) women, 7 (6.48%) men, mean age 48.87±17.8 (range 19-80) years) had an individual score 4 and above on any three items. Significant correlations were found between SD and older age (p=0.001) and between more pronounced symptoms regarding SD on ASEX and female gender (p=0.000). There were no significant correlations between the type of epilepsy and SD, nor between the AEDs (old generation vs. modern) and SD. Significant correlations were found between the SD and more pronounced depressive symptoms (p=0.003) and between the SD and a lower quality of life (p=0.001). CONCLUSIONS: Results of our study suggest SD is experienced by around one-third of patients in our group, which is similar to the previous percentage of SD reported in the community sample. Women were found to experience more pronounced symptoms of SD on ASEX. Symptoms of SD were found to be significantly correlated with older age, female gender, lower quality of life and depressive symptoms, while no significant correlations were found with the type of epilepsy and the AEDs.

Improvement of Quality of Life after Radical Prostatectomy.

Prostate cancer screening has increased the number of patients eligible for radical prostatectomy (RP), but this curable surgery also increases the risk of postprostatectomy erectile dysfunction and urinary incontinence, and although these adverse effects may vary depending on their incidence, severity and duration they are present in most men who undergoing RP, exposing them to psychosocial problems, increasing health care costs and reducing labour productivity, therefor it is of great importance to reduce or even prevent them. Pelvic physical rehabilitation is a relatively simple, non-invasive, outpatient method that, if applied properly before and/or after RP, can significantly reduce adverse effects, increase patient quality of life and satisfaction with surgery, but also reduce health care costs and accelerate return to work. It is therefore important that our patients and physicians are aware of the benefits of a pelvic muscle training program.

Extensive Abdominal Skin Necrosis Following Anterior Component Separation for a Large Ventral Hernia: A Case Report.

Introduction: Hernia surgery is one of the most common operative procedures, performed in about 20 million cases per year all over the world, with ventral hernia accounting for about 30% of the cases. Although the introduction of the anterior component separation (ACS) method, popularized primarily by Oscar Ramirez, has greatly facilitated the closure of the largest abdominal wall defects, the 30-year experience in this technique has pointed to the risk of ischemic skin complications consequential to the major subcutaneous tissue dissection required. The aim of this case presentation of a patient who developed extensive necrosis of the abdominal wall skin following ACS procedure is to emphasize the importance of preserving rectus abdominis perforator blood vessels in order to preserve skin vitality. Case Presentation: We present a case of a 58-year-old female patient with a large recurrent ventral hernia. The hernial defect was closed by placing a large (30 × 25 cm) polypropylene mesh in the retro-rectus space using the Rives-Stoppa technique. To facilitate upper fascia closure ACS according to Ramirez was performed bilaterally. The rectus perforator vessels were not preserved. Recovery of the patient was complicated with the extensive abdominal skin necrosis which was successfully treated with negative pressure wound therapy. Discussion: Transection of the musculocutaneous perforators of the epigastric artery during ACS results with the compromised blood supply of the abdominal skin depending solely upon the intercostal arteries. Skin ischemia following ACS is a serious complication that can be presented with extensive necrosis associated with high morbidity and even mortality, while the treatment is long lasting, complex, and expensive. Considering the ever-increasing prevalence of large ventral hernias, ever greater popularity of the ACS technique, and the growing proportion of surgeons performing large ventral hernia operations independently, we think that the role of preserving perforated rectus vessels has not been emphasized enough. Therefore, the objective of this case study is to stimulate surgeons to preserve skin vascularity and promote it in their routine in order to avoid these severe postoperative complications.

Lower Urinary Tract Symptoms and Depression in Patients with Multiple Sclerosis.

BACKGROUND: Both depression and lower urinary tract symptoms (LUTS) may be present in patients with multiple sclerosis (MS). The objective of this study was to give an insight on depression and LUTS in patients with MS in Croatia and to determine the possible association between LUTS and depression in patients with MS. SUBJECTS AND METHODS: This was a prospective cross-sectional study conducted in a tertiary healthcare center in Croatia. Hundred and one consecutive patients with MS (75 female, 26 male, mean age 42.09 (range 19-77) years, mean Expanded Disability Status Scale (EDSS) score 3.1 (range 0.0-7.0)) participated in this study. We evaluated LUTS and related quality of life (QoL) using three International Consultation on Incontinence Questionnaires (ICIQ) enquiring about overactive bladder (ICIQ-OAB), urinary incontinence short form (ICIQ-UI SF) and lower urinary tract symptoms related quality of life (ICIQLUTS-QoL). ICIQ-OAB and ICIQLUTS-QoL were for this purpose with permission successfully translated and validated into Croatian, while ICIQ-UI SF was already previously validated for the Croatian language. Information regarding treatment for depression was obtained during the medical interview. Data were analyzed and interpreted using IBM SPSS Statistics for Windows, version 23.0 (IBM Corp., Armonk, N.Y., USA). RESULTS: 89.10% (N=90) patients with MS reported urgency with urge urinary incontinence (UUI) present in 70.29% (N=71). 81.18% (N=82) patients reported nocturia, and 90.09% (N=91) reported feeling drowsy or sleepy during the day due to bladder symptoms. Neurological deficit measured by EDSS was found to positively correlate with LUTS on all three questionnaires: ICIQ-OAB (r=0.390, p<0.05), ICIQ-UI SF (r=0.477, p<0.01) and ICIQ-LUTSQoL (r=0.317, p<0.05). 25 patients were in treatment for depression. There were no significant differences between female and male patients regarding treatment for depression (χ2=0.018, df=1, p>0.05). Results on ICIQ-UI SF showed that depressive patients had more pronounced LUTS (t=2.067, df=99, p<0.05), which was also true for the ICIQ-LUTSQoL (t=-2.193, df=99, p<0.05). Positive correlations were found between depression and LUTS on ICIQ-UI SF (r=0.203, p<0.05) and ICIQ-LUTSQoL (r=0.215, p<0.05). CONCLUSION: This study gives insight into the presence of depression and LUTS in Croatian patients with MS for which purpose ICIQ-OAB and ICIQ-LUTSQoL were with permission successfully translated and validated into Croatian. The connection between depression and LUTS must be considered when managing patients with MS.

Bone morphogenic proteins-2, -4, -6 and 7 in non-muscle invasive bladder cancer.

Bone morphogenetic proteins (BMPs) are members of the transforming growth factor-ß (TGF-ß) family and may play an important role in the regulation of malignant cells in bladder cancer. The aim of the present study was to investigate BMP expression in non-muscle invasive bladder cancer. Tumor tissue samples from 71 patients treated with transurethral resection and 10 samples of normal bladder tissue were stained using immunohistochemistry for BMP-2, -4, -6 and -7. The levels of BMP were correlated with the number and size of tumors in the bladder, the pathohistological findings as well as with tumor recurrence and progression. The results of the present study demonstrated that BMP-2 and -7 are highly expressed in normal bladder tissue, but significantly downregulated in cancer samples. This reduction correlates with a faster rate of tumor recurrence as well as with an increase in the number of recurrent tumors. There was no evident interrelation between BMP-2 and -7 reduction and changes in tumor grade and stage. In conclusion, BMP-2 and -7 are potential prognostic factors for tumor recurrence and further studies on BMP and bladder cancer are needed to confirm these results.

Retrospective Evaluation of the Diagnostic Accuracy of the Modified Alvarado Scoring System (MASS) in a Croatian Hospital.

OBJECTIVE: Diagnosing acute appendicitis (AA) is challenging and this has stimulated surgeons to develop scoring systems that could potentially decrease the rate of misdiagnosis in patients with suspected appendicitis. One of the most widely used today is the Modified Alvarado scoring system (MASS), however its sensitivity and specificity varies a great deal between studies. As a result, we wanted to assess the diagnostic accuracy of MASS retrospectively at our institution to achieve the highest possible value of sensitivity and decrease the number of false negative patients. MATERIALS AND METHODS: We retrospectively calculated MASS for all subsequent patients who had undergone an appendectomy at our institution between July 2015 and March 2017. RESULTS: In 118 out of 146 operated patients, AA was confirmed intraoperatively. There was a statistically significant difference between the average MASS score in the positive and negative appendectomy groups (6 v. 4, respectively, P<0.001), with a significantly higher number of females among the negative appendectomies (P<0.001). When lowering the cut-off to a value as low as ≥3, the sensitivity of the MASS score increased to 97.45% (95% CI: 92.7 - 99.5), thus obtaining a very low false negative rate of merely 2.55%. CONCLUSION: This retrospective diagnostic accuracy study confirmed the higher average MASS score in the group of patients with confirmed AA diagnosis. A MASS score above the proposed low cut-off value (≥3) can be a useful tool to help surgeons ruling in patients with AA in order to reduce the risk of missing diagnosis.

Functional promoter polymorphism of the neuronal isoform of tryptophan hydroxylase (Tph2) in suicide.

The association between suicide and G-703T polymorphism of the tryptophan hydroxylase 2 (TPH2), the rate-limiting enzyme in the biosynthesis of the neurotransmitter serotonin, was studied in a sample of 291 suicide victims and 280 healthy subjects of Croatian origin. No significant differences were found between the groups. Obtained results do not support involvement of the investigated polymorphism in the susceptibility to suicide completion.
