Ultrasonographic measurements of abdominal lymph nodes in growing puppies
The sonographic appearance of the normal abdominal lymph nodes in adult dogs has been well described, but the data in puppies are scarce and of poor quality. The aim of the current study was to evaluate any differences in abdominal lymph node sonographic measurements in puppies of various sizes and to determine whether any differences were correlated with growth and weight gain during the first 10 weeks of life. By an approach based on prospective and serial measurements, length, width and thickness of jejunal, medial iliac and hypogastric nodes were obtained in twenty-one healthy puppies of various sizes, at six (T0), eight (T1) and ten (T2) weeks of age. The relationship between body weight and length, width and thickness of lymph nodes was evaluated using a Pearson correlation analysis. An ANOVA test was used to compare the measurements at different ages. Jejunal and iliac lymph nodes were the largest in large breed dogs. In large-sized puppies only the length of the jejunal lymph nodes correlated positively with width and body weight. Length of medial iliac lymph nodes correlated positively with width and body weight in all three sizes. None of the measurements of hypogastric lymph nodes were related to body weight. In large-sized puppies jejunal and iliac lymph nodes increased in length and width with age; in medium-sized puppies only iliac lymph nodes increased; in small-sized puppies jejunal and iliac lymph nodes significantly decreased in length and thickness. In conclusion, the lymph node sizes in young animals are directly related to body weight and do not decrease with growth during the first 10 weeks of life, except in small-sized puppies

Autoimmune mastitis as a clinical manifestation of Behçet’s disease: a case report and a systematic literature review
Objective: Behçet’s disease (BD) is a rare autoimmune disorder of unknown origin that causes chronic and systemic inflammation in blood vessels. The condition is traditionally defined by oral and genital ulcers and uveitis; however, cutaneous, articular, neurologic, vascular, gastrointestinal, and pulmonary manifestations may also be observed. It is more prevalent throughout the Silk Road, such the Mediterranean basin and the East Asia. There have been reported only four cases of BD targeting the breast. We herein present a case report of an autoimmune mastitis (AM) in a 23-year-old patient diagnosed for BD treated surgically.
Case Presentation: The patient is a 23-year-old Italian female who reported recurrent aphthous ulcers of the oral mucosa, occasional vaginal dryness, and genital lesions, diagnosed for BD according to the International Study Group (ISG) criteria and the skin biopsy. The patient referred to our department for examination of a painful and ulcerating lump at the 5 o’clock position of the right breast, which had been present for one month.
Results: In our case, we opted for a surgical approach, which proved to be effective in treating the lesion. Considering the relapsing and remitting nature of BD, surgical intervention is questionable when compared to appropriate conservative treatment.
Conclusions: A conservative approach should be evaluated first, in order to have regard to the recurrent course of the disease and to the risk that numerous surgical procedures may result in irreversible aesthetic damage
IL-1 receptor antagonist ameliorates inflammasome-dependent inflammation in murine and human cystic fibrosis
Dysregulated inflammasome activation contributes to respiratory infections and pathologic airway inflammation. Through basic and translational approaches involving murine models and human genetic epidemiology, we show here the importance of the different inflammasomes in regulating inflammatory responses in mice and humans with cystic fibrosis (CF), a life-threatening disorder of the lungs and digestive system. While both contributing to pathogen clearance, NLRP3 more than NLRC4 contributes to deleterious inflammatory responses in CF and correlates with defective NLRC4-dependent IL-1Ra production. Disease susceptibility in mice and microbial colonization in humans occurrs in conditions of genetic deficiency of NLRC4 or IL-1Ra and can be rescued by administration of the recombinant IL-1Ra, anakinra. These results indicate that pathogenic NLRP3 activity in CF could be negatively regulated by IL-1Ra and provide a proof-of-concept evidence that inflammasomes are potential targets to limit the pathological consequences of microbial colonization in CF
The Effect of coronavirus (COVID-19) on breast cancer teamwork: A multicentric survey
Background/Aim: Despite the large amount of clinical data available of Coronavirus-19 (COVID-19), not many studies have been conducted about the psychological toll on Health Care Workers (HCWs). Patients and Methods: In this multicentric descriptive study, surveys were distributed among 4 different Breast Cancer Centers (BCC). BCCs were distinguished according to COVID-19 tertiary care hospital (COVID/No-COVID) and district prevalence (DP) (High vs. Low). DASS-21 score, PSS score and demographic data (age, sex, work) were evaluated. Results: A total of 51 HCWs were analyzed in the study. Age, work and sex did not demonstrate statistically significant values. Statistically significant distribution was found between DASS-21-stress score and COVID/No-COVID (p=0.043). No difference was found in the remaining DASS-21 and PSS scores, dividing the HCWs according to COVID-19-hospital and DP. Conclusion: Working in a COVID-19-hospital represents a factor that negatively affects psychosocial wellbeing. However, DP seems not to affect the psychosocial well-being of BCC HCWs. During the outbreak, psychological support for low risk HCWs should be provided regardless DP
Recent Innovations & Daily Problems. A new prosthesis in inguinal hernia repair:preliminary results of a pilot study.
Introduction: Elective surgery for inguinal hernia is affected by very
low mortality « 1 per 10000 operation); in contrast, when surgery
is carried out for complicated inguinal hernia, risks of postoperative
complication are higher. TAPP is a world-wide accepted surgical practice
in the treatment of elective bilateral or recurrent inguinal hernia,
above all in young patients. Few exploratory studies were published on
laparoscopic approach in the treatment of urgent complicated inguinal
hernia. Aim of this study was to analyze feasibility (operative time,
conversion rate), safety (postoperative morbidity, length of hospital
stay) and quality of life (acute and chronic pain, return to work) of
trans-abdominal pre-peritoneal laparoscopic hernia repair in acute
incarcerated inguinal hernia. Rationale of laparoscopic trans-abdominal
approach is the easier hernia reduction under vision and a better
exploration of the abdominal cavity.
Methods: from September 2012 to September 2013, 15 consecutive
patients admitted in emergency at the Division of General Surgery of
University "Sapienza", Polo Pontino, for acute incarcerated inguinal
hernia were submitted to TAPP using 3 trocars (1 of 10 mm and 2 of
5mm) and polyester prosthesis fixed by fibrin glue. Exclusion criteria
for laparoscopic approach were age III, previous
abdominal surgery, signs of strangulated hernia. All of them were
evaluated for operative time, conversion rate, postoperative morbidity,
organ resection or other surgery required. All patients were scored for
pain by Visual Analogic Scale (VAS) during postoperative in hospital
stay at 7 days, 1,6 and 12 months after surgery.
Results: median follow-up was 16 months and 12 as minimum. In all
cases reduction of hernia was always possible and none conversion
to open surgery was recorded, median operative time was 89 minutes
(55-137 as range), omental resection was carried out in one patient
(6,6%), no other organ resections needed, whereas contralateral hernia
was diagnosed and repaired at the same time in 4 patients (26,6%). No
major complications were observed, median blood loss was 100 ml,
minor morbidity was contained to 18% represented by fever and
wound infection of surgical umbilical scar. Median in hospital stay
was 1,5 days with 1-5 days as range. Postoperative median acute pain,
measured by visual analogic scale (VAS), was 2 (range:0-4), none
patient referred any pain during follow-up. Median time of return to
work was 6,5 days, ranged between 3 to 15 days. Patients' compliance
to treatment and to follow-up was complete as well their satisfaction. Conclusions: In centres skilled for laparoscopy in emergency, TAPP
could be considered a feasible and safe technique. In well-selected
patients (especially if emolled in controlled clinical trial) TAPP could
represent an alternative surgical approach for complicated incarcerated inguinal hernia to conventional open surgery even in urgency. The
main advantages of laparoscopic approach are the ability to perform
surgical hernia reduction under vision, a better exploration and evaluation
of abdominal cavity and diagnosis and treatment of eventual
contralateral defect of wall, otherwise often missed. Finally, the good
control of acute and chronic pain, faster return to normal activity and
work, better aesthetic results contributed to total satisfaction and compliance
of the patients
Elastofibroma dorsi – differential diagnosis in chest wall tumours
BACKGROUND: Elastofibromas are benign soft tissue tumours mostly of the infrascapular region between the thoracic wall, the serratus anterior and the latissimus dorsi muscle with a prevalence of up to 24% in the elderly. The pathogenesis of the lesion is still unclear, but repetitive microtrauma by friction between the scapula and the thoracic wall may cause the reactive hyperproliferation of fibroelastic tissue. METHODS: We present a series of seven cases with elastofibroma dorsi with reference to clinical findings, further clinical course and functional results after resection, as well as recurrence. Data were obtained retrospectively by clinical examination, phone calls to the patients' general practitioners and charts review. Follow-up time ranged from four months to nine years and averaged 53 months. RESULTS: The patients presented with swelling of the infrascapular region or snapping scapula. In three cases, the lesion was painful. The ratio men/women was 2/5 with a mean age of 64 years. The tumor sizes ranged from 3 to 13 cm. The typical macroscopic aspect was characterized as poorly defined fibroelastic soft tissue lesion with a white and yellow cut surface caused by intermingled remnants of fatty tissue. Microscopically, the lesions consisted of broad collagenous strands and densely packed enlarged and fragmented elastic fibres with mostly round shapes. In all patients but one, postoperative seroma (which had to be punctuated) occurred after resection; however, at follow-up time, no patient reported any decrease of function or sensation at the shoulder or the arm of the operated side. None of the patients experienced a relapse. CONCLUSION: In differential diagnosis of soft tissue tumors located at this specific site, elastofibroma should be considered as likely diagnosis. Due to its benign behaviour, the tumor should be resected only in symptomatic patients
Role of apoptosis in the pathogenesis of COPD and pulmonary emphysema
Chronic obstructive pulmonary disease (COPD) is characterised by chronic inflammation of the airways and progressive destruction of lung parenchyma, a process that in most cases is initiated by cigarette smoking. Several mechanisms are involved in the development of the disease: influx of inflammatory cells into the lung (leading to chronic inflammation of the airways), imbalance between proteolytic and anti-proteolytic activity (resulting in the destruction of healthy lung tissue) and oxidative stress. Recently, an increasing number of data suggest a fourth important mechanism involved in the development of COPD: apoptosis of structural cells in the lung might possibly be an important upstream event in the pathogenesis of COPD. There is an increase in apoptotic alveolar epithelial and endothelial cells in the lungs of COPD patients. Since this is not counterbalanced by an increase in proliferation of these structural cells, the net result is destruction of lung tissue and the development of emphysema. Data from animal models suggest a role for Vascular Endothelial Growth Factor (VEGF) in the induction of apoptosis of structural cells in the lung. Other mediators of apoptosis, such as caspase-3 and ceramide, could be interesting targets to prevent apoptosis and the development of emphysema. In this review, recent data on the role of apoptosis in COPD from both animal models as well as from studies on human subjects will be discussed. The aim is to provide an up to date summary on the increasing knowledge on the role of apoptosis in COPD and pulmonary emphysema
