RESUMEN

Many difficult decisions are faced in the early management of severely burned patient. The decision to amputate an extremity or extremities may be very difficult but reduce morbidity and enhance survival of the patient. In a total of 1144 patients from January 2000 and June 2011, there were 44 patients (3.8%) undergoing amputations of the digits or upper extremity proximal to the wrist or lower extremity above the ankle. Amputations were significantly higher in males and the mean hospitalization time was also significantly higher in these patients. Majority of the patients had non-viable tissue (79.5%) and nine patients (20.5%) had a septic focus as cause of amputation. The majority of amputations were caused by high-voltage electrical injury. Education and compliance with safety measures, as well as common sense and respect for the potential danger of electricity, are still essential for avoiding these injuries.

RESUMEN

AIM: The aim of this study is to describe our 10-year experience in patients with urogynecological and colorectal carcinomas with radiation enteropathy treated surgically as an emergency, and to reassess symptoms and mortality. PATIENTS AND METHODS: The study included 17 patients receiving emergency surgery for complications of radiotherapy. Data about the patients and outcomes of the treatment alternatives used were retrospectively analyzed. RESULTS: Of 17 patients, nine had colorectal cancer, six had gynecological cancer, and two had cancer of the urinary system. As an emergency, 12 patients had ileus only, one patient had intestinal fistulae and ileus, two patients had bleeding and ileus and two patients had perforation on admission. Seven patients underwent resection and anastomosis, two patients intestinal by-pass, four patients resection and ostomy and four patients bridectomy. Morbidity (75% for early complications and 100% for late complications) and mortality in the early postoperative period (25%) were higher in the patients undergoing bridectomy than in the patients undergoing other surgical methods. The rate of early and late complications (71.4% and 66.6%, respectively) was lower in the patients undergoing resection-anastomosis with a higher of quality life. Only 11 patients survived during a long follow-up period (64.7%). CONCLUSION: As the postoperative complication rate, overall and operative mortality of patients treated for radiation enteropaties as emergent surgery are high, specialists following this group of patients may favor removal of the pathologic tissue to avoid complications in the early and late postoperative period.

RESUMEN

BACKGROUND: We examined the effects of two doses of statins on liver regeneration through angiogenesis and its possible relation to acute phase responses. MATERIALS AND METHODS: Seventy-two rats were randomly divided into three groups: controls; low-dose atorvastatin (0.5 mg/kg/d); high-dose atorvastatin (2.5 mg/kg/d). Statin was administered daily by oral gavage for 7 days. After atorvastatin treatment, all animals in the three groups underwent 70% hepatectomy. Thereafter animals were subdivided into three subgroups, to evaluate the characteristics of liver regeneration proliferating cell nuclear antigen (PCNA), angiogenesis (KDR/Flk-1 [vascular endothelial growth factor-2]) and acute phase response (serum interleukin [IL]-6) at 12, 24, and 72 hours. RESULTS: At the 24 hours posthepatectomy, low-dose compared with high-dose atorvastatin increased liver regeneration (P = .004) and angiogenic responses compared also to controls (P = .026 and P = .059). However, there appeared no difference in IL-6 expression (P = .159). At the 72 hours posthepatectomy, low-dose atorvastatin treatment increased liver regeneration compared with controls (P = .047), but it showed no significant difference from the high-dose treatment (P = .109). Low doses of statin increased angiogenic responses compared with both control and high-dose animals (P = .016 and P = .002). Moreover, the high-dose group displayed decreased angiogenic responses compared with the control group (P = .044). Serum IL-6 expression was significantly greater among both low- and high-dose groups compared with controls (P = .005 and P = .003, respectively). CONCLUSIONS: Low-dose statin treatment increased KDR/Flk-1-dependent angiogenesis, which resulted in an increased regeneration response. In contrast, high-dose statin therapy decreased angiogenesis without affecting long-term regeneration responses. Finally, statin therapy may contribute to liver regeneration due to prolonged IL-6 expression independent of statin doses.

RESUMEN

PURPOSE: to analyze the effect of anxiety and depression on the postoperative complications and length of hospitalization of patients with breast cancer. Beck's Depression Inventory (BDI) and Hospital Anxiety and Depression Scale (HADS) were filled out by the patients pre-operatively. Patients were asked to rate their pain by the visual analogue scale (VAS) after surgery. Age, seroma volume, day of drain withdrawal, complications, and pathological stages were noted. The median age of 49 patients with the diagnosis of breast cancer was 51 (36-80). There was a significant correlation between the pain score and Beck, HADS, HADS (anxiety) and HADS (depression) (8 hours ; p = 0.021, 0.001, 0.004, 0.005 and 24 hours ; p = 0.005, 0.012, 0.006, 0.120). The mean HADS depression score in those patients with complications was 9.1 +/- 4.2 and that of patients with no complications was 6.6 +/- 3.1 (p = 0.047). The mean hospital stay of patients with a normal HADS score (< 19) was 2.9 +/- 1.1 days, whilst that of patients with an abnormal HADS score was 3.8 +/- 1.2 days (p = 0.016). Patients with abnormal HADS anxiety and abnormal HADS (total) scores had an earlier stage of breast cancer (p = 0.077, p = 0.063). The psychological status of breast cancer patients effects their postoperative recovery period and it is easy to diagnose these patients by some brief questionnaires.

RESUMEN

PURPOSE: To reveal clinical and diagnostic findings in patients with mesenteric tumours and to give an insight into the follow-up of these patients. BACKGROUND: Primary tumours of the mesentery are very infrequent. These tumours are cystic or solid and show benign or malignant clinical behaviour. In this article, we report clinical and radiological findings from eight cases of mesenteric tumours. PATIENTS AND METHODS: This study included eight patients with mesenteric tumours who underwent computed tomography in the Department of General Surgery, Baskent University, between December 2003 and April 2007. RESULTS: Three mesenteric tumours were solid and five had cystic patterns. Seven were excised totally on laparotomy and one was excised on laparoscopy. None of the patients showed malignant progression. CT showed mesenteric cysts in only two cases, but failed to show solid tumours: the pre-operative diagnosis was made accurately in just (2/8) 25% of the patients. CONCLUSIONS: It can be concluded that pre-operative CT is generally helpful, but inconclusive in an accurate diagnosis of mesenteric tumours. Surgery is required to make a definitive diagnosis of mesenteric tumours and to avoid complications.

RESUMEN

Port site metastasis after laparoscopy is a rarely seen intraabdominal malignancy independent of tumor stage. We present an unusual case of port site adenocarcinoma metastasis from unknown origin following laparoscopic cholecystectomy. A 52-year-old woman with a previous renal transplant underwent a laparoscopic cholecystectomy for symptomatic cholelithiasis. Six months later, she was admitted to the hospital with a complaint of a mass at the four trocar sites. A biopsy from the port sites led to the diagnosis of adenocarcinoma metastasis. Port site metastasis after laparoscopic cholecystectomy is seen especially after gallbladder cancer, and less frequently after intraabdominal malignancy independent of tumor stage. Our patient illustrated that port site metastasis probably spread from an undetected cancer site of an early stage intraabdominal tumor. Immunosuppression may have increased the likelihood of tumor seeding at the port sites.

RESUMEN

In Turkey, burns represent a relatively small number of injuries overall, but they continue to be a major public health problem. Our aim in this study was to identify risk factors that affect outcome in burn patients hospitalized in the southern part of our country, with special emphasis on electrical burns. The database for 109 burn patients who were admitted to our burn center from April, 2000, through August, 2001, was retrospectively analyzed. Electrical injury was the cause of burn in 23 (21%) of the 109 cases. The burn causes differed among age groups and between the sexes, with males constituting 95% of the electrical burn patients. The mortality rate for the electrical burn group was lower than the rate for the rest of the burn patients (1/23 vs 17/86, respectively; P <.001); however, the opposite was true for complication rate (10/23 vs 5/86, respectively; P <.001), cost of treatment (8351 US dollars vs 5122 US dollars, respectively; P =.009), and length of hospital stay (39.9 vs 26.2 days, respectively; P < 0.001). The rate of electrical burn injury in Turkey has changed very little in the past two decades. This underlines the need for stronger efforts aimed at prevention, such as better public education and strict regulations regarding the distribution and use of electricity.

RESUMEN

Introduçäo: Os alfa-bloqueadores säo hoje as drogas de escolha no tratamento clínico de pacientes com hiperplasia prostática benigna (HPB). Os autores apresentam os resultados de um estudo prospectivo, randomizado, duplo-cego, e controlado por placebo da alfuzosina no tratamento de pacientes com HPB. Material e métodos: 31 pacientes foram randomizados em dois grupos: alfa-bloqueador seletivo alfuzosina na dose de 5 mg duas vezes ao dia (n=16) ou placebo (n=15) por 12 semanas. Os pacientes foram selecionados de acordo com critérios de inclusäo e exclusäo que, de forma geral, incluiram pacientes com 50 anos de idade ou mais, escore internacional de sintomas prostáticos (EISP) de 12 pontos, índice de qualidade de vida (IQV) de 3 pontos ou mais, e fluxo urinário máximo (Fmáx) entre 5 e 15 ml/s. Resultados: Näo houve diferença na taxa de melhora do EISP (37 por cento versus 29 por cento, p=0,446) e IQV (15 por cento versus 21 por cento, p=0,446) entre o grupo alfuzosina e o grupo placebo. No entanto, embora marginalmente significante, o Fmáx mostrou uma melhora marcante após a alfuzosina quando comparado ao placebo (50 por cento versus 5,5 por cento, p=0,06). A incidência de efeitos colaterais foi similar em ambos os grupos, alfuzosina e placebo (43,8 por cento versus 40 por cento, respectivamente). Conclusöes: O alfa-bloqueador alfuzosina näo é uma panacéia e, em alguns pacientes, a melhora clínica ocorre principalmente devido ao efeito placebo, que neste estudo resultou em aproximadamente 30 por cento de melhora do EISP (p=0,001), 21 por cento de melhora do IQV (p=0,017) e um aumento do Fmáx ò50 por cento em 26,5 por cento dos pacientes. Entretanto, o alfa-bloqueador alfuzosina tem um papel importante na abordagem clínica da HPB, já que seu mecanismo de açäo alivia o componente dinâmico da obstruçäo prostática, como demonstrado pela melhora do Fmáx.

RESUMEN

OBJECTIVES: In spite of its historical use, published data about phytotherapic products is characterized by the absence of well conducted studies, leading to conflictive and indefinite results about efficiency and safety of theses drugs. In that sense, we have analyzed the results of a combination of Pygeum africanum and stinging nettle (Urtica dioica) extracts in patients with benign prostatic hyperplasia (BPH), based in a double-blind, randomized, placebo-controlled protocol. MATERIALS AND METHODS: We have selected, according to inclusion and exclusion criteria, only patients with >or=50 years, presenting urinary symptoms assessed by the International Prostatic Symptoms Score (IPSS), with minimum score of 12, and Quality of Life (QoL) index of at least 3 points, rectal examination consistent with BPH, and maximum urinary flow rate (Q(max)) between 5 and 15 mL/s. Phytotherapic and placebo groups were formed by 27 and 22 patients, respectively. The major variables analyzed during the study were IPSS variation, Q(max), and side effects. Reduction of >or=30% and >or=50% in IPSS were the parameters used to define a clinically significant response (CSR). We have also analyzed >or=30% and >or=50% Q(max) increases. RESULTS: After six months of treatment we did not observe significant differences in clinical improvement potential between the phytotherapic combination and placebo groups. Percent IPSS drop of 21.6% in the phytotherapic group was similar to 19.7% obtained in the placebo group (p=0.928). Neither we observed any difference (p=0.530) for QoL improvement between phytotherapic (9.26%) and placebo (5.98%) groups. The alterations of Q(max) followed the trend line observed in clinical data, with no significant difference (p=0.463) in Q(max) increasing percent between phytotherapic (17.2%) and placebo (13.3%) groups. The CSR evaluation of clinical and urodynamic data was also similar between the groups. CONCLUSION: The combination of 25mg Pygeum africanum and 300mg stinging nettle extracts produced clinical and urodynamic effects similar to placebo in a group of HBP patients.

RESUMEN

Arbitrary primer polymerase chain reaction (AP-PCR) detected anonymous DNA polymorphisms between individual representatives of seven breeds of dogs, between members of a single breed, and between members of a single family of dogs. Short arbitrary sequence PCR primers and promoter/protein motif sequence primers typically amplified 15-30 bands ranging from 200-2000 bp in length. The average heterozygosity of 10 line bred Belgian sheepdogs (H = 0.024 +/- 0.011, mean +/- 95% CI) was significantly lower than that of a panel of unrelated beagles (H = 0.057 +/- 0.018, mean +/- 95% CI, P < .01). The average heterozygosity of a seven-breed panel was intermediate between the two (H = 0.043 +/- 0.011, mean +/- 95% CI) and not significantly different than either panel. One motif sequence PCR primer pair yielded products that strongly differentiated between Belgian sheepdogs, beagles, and members of five other breeds. AP-PCR could be used to generate DNA fingerprints that distinguish between dog breeds, as well as to provide markers in this sparsely mapped genome.
