Synchronous biliary gallstones and colorectal cancer: A single center analysis.

Gallstones and colorectal cancer (CRC) are two common disorders that may develop simultaneously. In such situations, there is a significant chance of missing one of the conditions due to the primary clinical presentation. Late detection, diagnosis and treatment can be especially problematic in the case of unrecognized CRC. In the present study, the medical charts were retrospectively reviewed for all consecutive patients who were treated in the Second Department of Surgery, University Emergency Hospital Bucharest (Romania) between February 2015 and December 2017 following a diagnosis of CRC and/or biliary stones. There were 203 patients with CRC, 433 with biliary gallstones and 19 patients with both conditions. There were 125 men (61.6%) in the CRC group and 138 men (31.9%) in the gallstone group. The average age was 54.1±15.9 years in the gallstone group and 66.1±11.6 years in the CRC group. Obesity was observed in 96 patients (22.2%) with gallstones and in 14 (6.9%) patients in the CRC group. In the CRC group, 80 patients had medical comorbidities (39.4%), while in the gallstone group 126 patients (29.1%) had medical comorbidities. Bivariate analysis comparing gallstone only vs. gallstone and CRC identified age (P=0.001), male sex (P=0.001) and thyroid disease (P=0.001) as significant factors associated with synchronous diagnosis. The multivariable logistic regression of factors predicting CRC in patients with gallstones identified age (OR, 1.06; 95% CI, 1.023-1.105; P=0.002) and thyroid diseases (OR, 11.15; 95% CI, 2.532-49.06; P=0.001) as independent factors. There were significant differences regarding the location of the tumor between the CRC-only group and the gallstone and CRC group (P=0.001): Rectum (39.7 vs. 5.3%), left colon (26.6 vs. 21.1%), transverse colon (13 vs. 26.3%) and right colon (20.7 vs. 47.4%). The study concluded that, in patients with gallstones, age and thyroid conditions were significantly associated with CRC. Patients with a synchronous diagnosis of gallstones and CRC had significantly more right-sided CRC compared with regular CRC.

Mucinous appendiceal neoplasm: A case report.

BACKGROUND: Primary appendiceal tumors are histologically diverse and have an insidious onset and few specific clinical manifestations. In the majority of cases, these tumors are discovered after appendectomy during pathological exam of the resected tissue. Treatment may include appendectomy (simple or radical) and right hemicolectomy depending on factors such as histological type, tumor size and lymph node/organ involvement. The aim of this case study is to describe a rare case of a giant appendicular mucocele and raise awareness of this condition and its management options and follow-up protocol. CASE SUMMARY: We present the case of a 43-year-old patient who presented to our emergency department with mild right lower quadrant pain. After the initial check-up and imaging exams, he underwent surgery, where a giant 20 cm × 13 cm appendicular tumor was found and resected. Appendicular mucocele was suspected due to the macroscopic appearance and was later confirmed by the pathological exam. The patient's postoperative evolution was uneventful, and after discharge, he was included in our follow-up program. CONCLUSION: In conclusion, mucinous appendiceal neoplasms embody a rare pathology; they are asymptomatic or have few, unspecific clinical signs and in many cases are discovered after appendectomy.

An overview of resistance profiles ESKAPE pathogens from 2010-2015 in a tertiary respiratory center in Romania.

Lower respiratory tract infections (LRTIs) is an umbrella term that covers a wide spectrum of diseases, comprising mild and severe, acute and chronic conditions. A wide spectrum of pathogens can be implicated, from viruses to pyogenic and atypical bacteria. A special place should be reserved for slow growing bacteria (Mycobacteria spp., Nocardia spp.) and parasites (i.e., hydatic cysts caused by Echinococcus granulosus). OBJECTIVE: The objective of this study is to observe, analyze and establish the drug susceptibility patterns for Enterococcus spp., Staphylococcus aureus, Klebsiella spp., Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter spp. (the ESKAPE pathogens) in the "Marius Nasta" Institute for Pulmonary Medicine (MNIPM), Bucharest, Romania. MATERIALS AND METHODS: A retrospective healthcare record based study was undertaken to establish the drug susceptibility patterns. We assessed all antibiograms of the ESKAPE pathogens isolated from respiratory samples from adult inpatients hospitalized between 2010-2015 at the MNIPM. RESULTS: We analyzed 2859 isolates (61% of the 4683 ESKAPE isolates). P. aeruginosa was the most frequent pathogen, while Enterococcus spp. and Enterobacter spp. were practically non-present. The antibiotic profile of P. aeruginosa isolates presented more resistance in the Intensive Care Unit (ICU)÷Surgery wards, probably resulting from antibiotic pressure. The other non-fermenter, A. baumannii, while less frequent (and the only pathogen more frequent in the surgery department) had an even more resistant profile, to almost all antibiotics, with the exception of Colistin. Methicillin-resistant S. aureus (MRSA) accounted for about 60% of all isolates, more in the ICU÷Surgery ward. K. pneumoniae presents a less resistance and shows more stability when analyzing the antibiogram pattern in the Medical wards. DISCUSSION: For methodological or procedural reasons, Enterococcus spp. and Enterobacter spp. were underrepresented in the study. Interventional programs comprising antibiotic stewardship and active surveillance need to be implemented to alleviate the antibiotic profile. Further research needs to focus on more detailed characterization of the molecular mechanisms leading to the high resistance detailed herein. CONCLUSIONS: This study adds to the body of literature reporting the antibiotic resistance landscape in Romania, for these highly resistant pathogens.

A rare case of clear-cell carcinoid of appendix.

The carcinoids are the most frequent type of tumors arising from the appendix. In the majority of cases, these tumors are asymptomatic and usually are discovered after appendectomy. Definitive diagnosis relies on pathological examination of the resected appendix, size of the tumor being critical for the further management. Clear-cell change in neuroendocrine tumors (NETs) has rarely been described in the appendix. We choose to present a clear-cell carcinoid subtype of appendiceal NET to raise awareness on this potentially curable and rare condition that can be overlooked. We highlight the importance of the pathological exam and the morphological and immunohistochemical behavior of the tumor in confirming the diagnosis and aiding in the treatment decision making. Also, important entities should be considered in the process of differential diagnosis such as goblet-cell carcinoid or renal-cell÷ovarian carcinoma.

Hydatid Cyst of the Calf - a Rare Pathology that May Be Overlooked.

Hydatid disease is caused by an infestation with the tapeworm Echinococcus. Each parasite can produce thousands of eggs with oncospheres that can migrate to the liver or lungs and rarely to other sites, including muscles. The aim of this case study is to describe a rare case of a patient with an atipical hydatid cyst location and to raise awareness of this condition. We present the case of a 28-year-old female patient admitted in our clinic with a lump in her right calf who underwent surgical excision, hydatid cyst being suspected due to the aspect of the thin cyst wall membrane, confirmed by hystopathological examination. The post-operative course was uneventful and the patient was discharged five days later with medical treatment with albendazole. In conclusion, hydatid disease must be kept in mind as a differential diagnosis when facing a muscle cystic mass, even though it is very rare, and a good medical and surgical management may determine a permanent cure.
