Morganella sp. infection in scent gland of corn snake (Pantherophis guttatus) - case report / Infecção por Morganella sp. em glândula de cheiro de corn snake (Pantherophis guttatus) - relato de caso

The corn snake (Pantherophis guttatus) is a non-venomous snake from the Colubridae family. The pair of scent glands is indispensable in the physiology of reproduction and defense of the species. This structure is located caudal to the cloaca. It is responsible for releasing a thick material based on lipids containing pheromones that perform functions associated with animal behavior and survival. This work aims to report infection by Morganella sp. in a scent gland in a female corn snake, evidencing the diagnosis and treatment. An increase in volume was seen in the final third, proximal to the cloaca, firm consistency, immobile, and approximately 4 cm long and painful to touch. Samples of the material were collected for bacterial culture and antibiogram examination, being positive for bacteria of the genus Morganella. Based on the result of the antibiogram, it was possible to determine the most appropriate therapeutic protocol, with the referral to perform the surgical procedure to remove the tissue compromised by the infection, remaining stable until the removal of the stitches 40 days after the procedure, with total surgical wound healing.(AU)

A corn snake (Pantherophis guttatus) é uma serpente não peçonhenta, da família Colubridae. Na fisiologia da reprodução e defesa da espécie, o par de glândulas de cheiro é indispensável. Essa estrutura está localizada caudal à cloaca e é responsável pela liberação de um material espesso à base de lipídeos, contendo feromônios que exercem funções associadas ao comportamento animal e à sua sobrevivência. O objetivo desse trabalho é relatar uma infecção por Morganella sp. em glândula de cheiro em uma fêmea de corn snake, evidenciando o diagnóstico e tratamento. Observou-se um aumento de volume no terço final, proximal a cloaca, de consistência firme, imóvel e com aproximadamente 4 cm de comprimento e sensibilidade dolorosa ao toque. Foram coletadas amostras do material para cultura bacteriana e exame de antibiograma, sendo positivo para bactérias do gênero Morganella. Com base no resultado do antibiograma, foi possível determinar o protocolo terapêutico mais adequado, como o encaminhamento para realização do procedimento cirúrgico para remoção do tecido comprometido pela infecção, se mantendo estável até a remoção dos pontos, 40 dias após o procedimento, com total cicatrização da ferida cirúrgica.(AU)

Enterobacter cloacae infection of the shoulder in a 52-year-old woman without apparent predisposing risk factor: a case report and literature review.

BACKGROUND: Enterobacter cloacae (E. cloacae) is one of the commensal flora in the human intestinal tract and a prevalent nosocomial pathogen, which rarely causes infectious osteoarthritis in immunocompetent patients without recent trauma or surgery. Here, we report the first case of septic monoarthritis of the shoulder caused by E. cloacae in an immunocompetent patient. CASE PRESENTATION: A 52-year-old female with a 6-year history of right shoulder pain was referred to our emergency department due to fever, acute severe shoulder pain, and swelling. Blood test showed elevated inflammatory markers. The patient denied any recent invasive surgical procedure and trauma. She was misdiagnosed with a frozen shoulder, and the anti-inflammatory painkiller celecoxib for symptomatic treatment was ineffective. Magnetic resonance imaging (MRI) showed a shoulder joint abscess and supraspinatus tendon tear. The joint aspirate culture showed E. cloacae. After late diagnosis, she was treated with levofloxacin and underwent surgical debridement and irrigation. Her follow-up data revealed that she did not suffer from shoulder swelling and severe pain. CONCLUSION: This is a rare case of E. cloacae infected arthritis of the shoulder in an immunocompetent patient with a rotator cuff tear, indicating that even if the symptoms and age of the patients match the characteristics of frozen shoulder, the possibility of septic arthritis should be considered in the presence of fever and increasing inflammatory markers. The cases of our literature review suggest that the patients subjected to invasive procedure may develop a subsequent E. cloacae osteoarticular infection, regardless of being asymptomatic after the procedure.

Infection of finger caused by Morganella morganii leading to digital amputation: A case report.

RATIONALE: Digital infection is a common disease in clinic, featured by pain and swelling of digits. As far as we know, no article has reported a case of digital infected by Morganella morganii. PATIENT CONCERNS: A 58-year-old Chinese female complains about whitlow with pain and swelling for 2 weeks. She has a history of diabetes for 10 years. She received incision and drainage before coming to our hospital and preoperative X-ray of left ring finger presented no bone eroded. DIAGNOSIS: She is diagnosed with infection of ring finger caused by M morganii in our hospital. INTERVENTIONS: We perform aggressive operative debridement and drainage firstly. Meanwhile, we provide tissue samples for diagnosis and the result indicates M morganii infection. Then, she is treated with anti-infection therapy and regulation of diabetes. However, 1 week after first surgery, her condition deteriorate presenting bone erosion in distal phalanx of ring finger from X-ray. Considering severity of illness, we decide to perform digital amputation. OUTCOMES: At 3-month follow-up, the patient has a satisfactory result and X-ray shows no bone eroded. LESSONS: Clinicians should consider M morganii, which is rare in hand infection, as a cause of digital infection. This case reminds us that some whitlow is dangerous, amputation should be considered if necessary.

Liver abscess with Citrobacter koseri bacteremia.

Citrobacter koseri is a rare cause of liver abscess with two reported cases in diabetic patients. We report a rare case of C. koseri liver abscess with C. koseri bacteremia in an elderly male with chronic kidney disease. He presented vomiting and weakness without any other signs. He was diagnosed with liver abscess by ultrasound, and blood culture showed C. koseri growth. The patient was treated effectively with a course of antibiotics and drainage. When C. koseri is isolated in patients with comorbidity, such as chronic kidney disease, we should consider the possibility of abscess including liver abscess and utilize a combined treatment of drainage and course of antibiotics for mixed infection.

Necrotizing fasciitis of the hand: a case report.

Necrotizing Fasciitis is a rare life-threatening infection , usually polymicrobial, that frequently affects the extremities in as many as two thirds of the cases. It typically involves primarily the muscular fascia, and then spreads through muscular and subcutaneous tissues. The early diagnosis may be challenging , and appears to be crucial in the management of this condition. We report a case of a 45-year-old man, former drug abuser, diabetic, HCV +,  who developed a necrotizing fasciitis of the hand following a minor trauma. Early diagnosis based on clinical, laboratory (LRINEC score) and radiological findings, together with an accurate debridement of the affected site, allowed us to limitate the amputation to the third ray only. The reconstruction with the capitate osteotomy and the coverage with the posterior interosseous flap helped us in further reduction of the functional impairment of the hand.

[FOUR CASES OF THE PROSTATIC ABSCESS IN WHICH DRAINAGE WAS EFFECTIVE].

We encountered four prostatic abscess patients. Although antimicrobial therapies were ineffective, drainage was effective in all cases. Patient 1 had lung cancer and diabetes mellitus (DM), and patient 2 developed acute prostatitis after transrectal prostatic biopsy. Culture of the urine and blood revealed extended-spectrum beta lactamase (ESBL) -producing Escherichia coli (E.coli). Patient 3 had previously sustained spinal cord injury, and urinated by self-catheterization. Patient 4 had untreated, severe DM. Patient 1, 2 and 3 had been treated by transurethral resection of the prostate (TURP). Patient 2 complained of ejaculatory incompetence after the surgery, and the symptom caused mental distress. Patient 4 was a 43-year-old man who had undergone transperineal needle aspiration under ultrasound guidance to avoid ejaculatory incompetence. The prostatic abscess disappeared in all cases after drainage without recurrence.

Severely infected pneumoceles of the frontal sinus in patients with mental retardation and brain atrophy treated by endoscopic sinus surgery.

We herein present three cases of abnormally expanded frontal sinuses (pneumoceles) with severe infection in patients with mental retardation and brain atrophy. Two patients previously underwent laryngotracheal separation surgery, and bacteriological examinations of purulent nasal discharge revealed infections caused by drug-resistant bacteria such as Pseudomonas aeruginosa and Acinetobacter baumannii. As conservative medical treatments were ineffective, all three patients were treated by computed tomography-guided endoscopic sinus surgery. This navigation system is useful for safer surgery in the area of anatomic deformity. The clinical findings, possible etiologies and surgical treatment of these cases are discussed.

A novel case of Raoultella planticola osteomyelitis and epidural abscess.

A spinal epidural abscess is the collection of pus in the epidural space, and is a potentially life-threatening condition that requires early detection and prompt management. Almost two-thirds of cases are caused by Staphylococcus aureus, followed by Gram-negative bacilli which account for approximately 16% of cases. Raoultella planticola is an emerging pathogen, and is an extremely rare cause of invasive infection in humans. It has been reported to cause urinary tract infections, pneumonia, bacteraemia, cholangitis, cholecystitis, conjunctivitis and soft tissue infections. We report the first case, to our knowledge, of R. planticola osteomyelitis and spinal epidural abscess.

Bronchoscopic Drainage of Lung Abscesses Using a Pigtail Catheter.

BACKGROUND: Lung abscesses are commonly treated with antibiotics. However, some patients fail to respond and may require percutaneous catheter drainage or surgical intervention. Bronchoscopic drainage (BD) of lung abscesses emerged as a therapeutic alternative in selected patients. OBJECTIVE: To describe our experience with 15 patients who underwent BD at our center during 2006-2016. METHODS: Patients underwent flexible bronchoscopy. Under fluoroscopic guidance, a pigtail catheter was introduced into the abscess cavity, its correct position being confirmed by the injection of contrast medium. The catheter remained in place for a few days and was flushed repeatedly with antibiotics. RESULTS: Fifteen patients (9 males; median age 59 years) underwent 16 BD procedures. A pigtail catheter was successfully inserted and pus was drained from the abscess cavity in 13 procedures (81%) conducted in 12 patients, leading to rapid clinical improvement in 10 of them; resolution of fever occurred a median of 2 days (range <1-4) following pigtail insertion, and patients were discharged after 8 days (range 4-21). The pigtail catheter was extracted after a median of 4 days (range 2-6). CONCLUSION: BD of lung abscesses was achieved in 13 out of 16 procedures, leading to rapid improvement in the majority of patients. This work adds to the existing literature in establishing this procedure as an acceptable therapeutic alternative in selected patients who fail to respond to antibiotics, especially those with an airway obstruction or a fairly central lung abscess.

Splenic abscess owing to cancer at the splenic flexure: A case report and comprehensive review.

BACKGROUND: The cancer of the splenic flexure of the colon is a rare medical entity with severe morbidity because of its insidious onset. METHODS: We present the case of a 59-year-old male patient with dull left upper quadrant pain, leukocytosis, and anemia. A splenic abscess described as an air-fluid level with splenocolic fistula was found on CT scan imaging. Surgery was done for splenic pus drainage. He was again admitted 2 months later for intestinal obstruction. RESULTS: An exploratory laparotomy showed multiple hard, gray liver nodules as well as a hard mass in the small bowel. Owing to extensive adhesions and a late stage of cancer involvement, the splenic flexure tumor was not resected. A loop transverse colostomy was done and a Coloplast Colostomy bag placed. We also reviewed the literature-linking colon cancer and splenic abscess with specific attention to the carcinoma of the splenic flexure. As the latter invades through the spleen matter, there is the creation of a splenocolic fistula, which allows the migration of normal gut flora into the spleen. This leads to the formation of the splenic abscess. CONCLUSION: This is the 13 case report pertaining to invading colonic cancer causing a splenic abscess. Although the treatment for splenic abscesses is shifting from splenectomy to image-guided percutaneous pus drainage, the few reported cases make the proper management of such complication still unclear.

Use of a contoured bioresorbable plate with a hemostatic plug to control life-threatening bleeding from the superior sagittal sinus during hemispherotomy: technical note.

Profuse bleeding originating from an injured cerebral sinus can be a harrowing experience for any surgeon, particularly during an operation on a young child. Common surgical remedies include sinus ligation, primary repair, placement of a hemostatic plug, and patch or venous grafting that may require temporary stenting. In this paper the authors describe the use of a contoured bioresorbable plate to hold a hemostatic plug in place along a tear in the inferomedial portion of a relatively inaccessible part of the posterior segment of the superior sagittal sinus in an 11-kg infant undergoing hemispherotomy for epilepsy. This variation on previously described hemostatic techniques proved to be easy, effective, and ultimately lifesaving. Surgeons may find this technique useful in similar dire circumstances when previously described techniques are ineffective or impractical.

[DYNAMICS OF INDICES OF A LOCAL IMMUNITY IN AN ACUTE APPENDICITIS].

Abstract The results of investigation on dynamics of a local immunity indices in an acute appendicitis, depending on the pathological process stage as well as on bacteriological investigation of parietal microflora of processus vermicularis, were adduced. The sIgA and lisocymal dynamics have witnessed that while a destructive process progressing their concentration was enhanced, and in a gangrenous acute appendicitis they practically disappeared. Due to affection of a barrier function of the processus vermicularis wall a favorable conditions were created for the microorganisms intramural translocation as well as to abdominal cavity.

Mycotic Aneurysm Due to Leclercia Adecarboxylata: A Complication of Vertebral Osteomyelitis.

Leclercia adecarboxylata is a gram-negative bacterium and member of Enterobacteriaceae family. It has most frequently been isolated from lower wounds as a part of mixed flora. Mycotic aneurysms were first described by Osler and were mostly associated with infective endocarditis. We present the case of a male who presented with limb vein thrombosis, fatigue, and a history of back pain. The computed tomography scan revealed a saccular aneurysm and combined vertebral osteomyelitis of the third lumbar vertebra. An endovascular aneurysm repair with a tubed endograft was performed. Two years after the initial therapeutic management, he developed buttock claudication because of ostial stenosis of both common iliac arteries and a "kissing-stent" technique was performed. This is the first case described regarding Leclercia adecarboxylata as an etiologic factor of infected aneurysm development, its management and the short-term outcome.

Necrotizing soft tissue infection following a peripheral bypass.

BACKGROUND: Necrotizing soft tissue infection (NSTI), formerly referred to as necrotizing fasciitis, is a rare but serious postoperative complication. NSTI following arterial bypass is seen only once in the literature (for a coronary artery bypass) and is not mentioned following peripheral bypass. Although surgical site infections have been studied extensively, there are limited published data on postoperative NSTI and no data for NSTI following peripheral arterial bypass. CASE PRESENTATION: Here we present the first, to our knowledge, reported instance of an NSTI following a lower extremity peripheral bypass. Despite the continued function of the bypass, the patient became rapidly systemically ill with a focus at the surgical site. Because of prompt surgical debridement, the patient survived this severe infection, though did require an above the knee amputation to control the rapid spread of the disease. The patient, a native of American Samoa, was infected with organisms infrequently associated with NSTI, Morganella morganii and Aeromonas hydrophila. This article discusses the diagnosis and treatment of this rare postoperative complication, along with a brief review of the microbiology of the disease. CONCLUSIONS: NSTI is a rare but lethal postoperative complication. To our knowledge, this is the first reported case of an NSTI following an arterial peripheral bypass. This patient survived because of prompt and aggressive intervention.

Cyst infection of intraductal papillary mucinous neoplasms of the pancreas: management of a rare complication: report of 2 cases.

The purpose of this study was to describe the cyst infection of intraductal papillary mucinous neoplasm in 2 patients. The patients were 62- and 74-year-old men. The initial symptom was acute febrile abdominal pain. Laboratory tests revealed severe infection (C-reactive protein concentrations were 23.3 µg/mL in patient 1 and 22.3 µg/mL in patient 2) and multilocular cystic masses (the diameters were 70 mm in patient 1 and 50 mm in patient 2) at the pancreatic head that involved peripancreatic vessels were demonstrated by computed tomography. Laboratory and radiographic findings were markedly improved by endoscopic transpapillary drainage. The enteric bacteria were detected in the drainage specimens. Curative resection was achieved, and histological findings indicated a carcinoma in situ in patient 1 and an invasive carcinoma in patient 2. Neither hyperamylasemia nor histological fat necrosis, frequently observed in acute pancreatitis, was evident. Both patients were free from recurrence after surgery (17 months in patient 1, and 18 months in patient 2). Cyst infection is an unknown complication of intraductal papillary mucinous neoplasm. Transpapillary drainage is highly recommended as an initial intervention. It is difficult to distinguish between cyst infection and unresectable invasive carcinoma with imaging modalities; however, surgical intervention after drainage may contribute to long-term survival.

Detection of Escherichia fergusonii by PCR-based DNA sequencing in a case of delayed-onset chronic endophthalmitis after cataract surgery.

UNLABELLED: We report a case of chronic low-grade endophthalmitis after cataract surgery presenting with recurrent episodes of severe anterior chamber reactions and hypopyon uveitis caused by Escherichia fergusonii, which was isolated from vitreous aspirate by polymerase chain reaction-based DNA sequencing. Polymerase chain reaction has emerged as an essential, powerful, and rapid laboratory diagnostic technique and a useful adjunct to the conventional gold standard. FINANCIAL DISCLOSURE: No author has a financial or proprietary interest in any material or method mentioned.

Endoscopic ultrasonography-guided transmural drainage of an infected hepatic cyst due to Edwardsiella tarda: a case report.

Infected hepatic cysts are very rare compared to simple liver cysts and abscesses. We treated a 77-year-old man with an infected hepatic cyst in the lateral segment caused by Edwardsiella tarda, which has not been previously reported as a pathogenic organism associated with infected hepatic cysts. Percutaneous drainage was temporarily effective, but infection recurred after the drainage tube was removed. We then inserted two drainage tubes into the cyst using an endoscopic ultrasonography (EUS)-guided technique, which was developed from EUS-guided fine needle aspiration (EUS-FNA). The internal drainage tube was a 7 Fr double pigtail stent, and the external tube was a 6 Fr nasobiliary drainage tube. Lavage through the external drainage tube was carried out for one week. The external drainage tube was discontinued when the patient's condition improved significantly. Sixteen days after tube insertion, he was discharged with the internal tube draining the hepatic cyst into the stomach. Fifteen months after EUS-guided drainage, CT examination showed no recurrence of the hepatic cyst. EUS-guided drainage is an effective treatment for infected hepatic cysts.

Early aetiological agent identification of osteomyelitis with the Light Cycler SeptiFast test from peripheral blood.

The commercial real-time PCR SeptiFast test allows identification of 25 bacterial and fungal species directly from peripheral blood in patients with bloodstream infections. A 22-year-old Caucasian woman reported an open femur fracture requiring a two step surgical procedure. After the second procedure the patient manifested sepsis and Enterobacter cloacae/aerogenes DNA was detected in the peripheral blood with the SeptiFast. Thereafter, femur osteomyelitis was diagnosed and E cloacae was cultured from intraoperative bone samples. The patient completed a 3-month course of antimicrobial therapy. Five months after therapy was discontinued, the patient remained symptom free, but delayed bone consolidation occurs. Molecular methods to identify aetiological agents in blood, in addition to conventional cultures, could represent an advantageous tool in clinical practice also in patients with post-traumatic bone infections.
