The mechanisms governing the abscopal effects of local radiotherapy in cancer patients remain an open conundrum. Here, we show that off-target intestinal low-dose irradiation (ILDR) increases the clinical benefits of immune checkpoint inhibitors or chemotherapy in eight retrospective cohorts of cancer patients and in tumor-bearing mice. The abscopal effects of ILDR depend on dosimetry (≥1 and ≤3 Gy) and on the metabolic and immune host-microbiota interaction at baseline allowing CD8+ T cell activation without exhaustion. Various strains of Christensenella minuta selectively boost the anti-cancer efficacy of ILDR and PD-L1 blockade, allowing emigration of intestinal PD-L1-expressing dendritic cells to tumor-draining lymph nodes. An interventional phase 2 study provides the proof-of-concept that ILDR can circumvent resistance to first- or second-line immunotherapy in cancer patients. Prospective clinical trials are warranted to define optimal dosimetry and indications for ILDR to maximize its therapeutic potential.

The sternalis is an occasional muscle of the pectoral region with a reported incidence of around 7.8%. Higher rates of occurrences have been noted in females and in Asians. The muscle becomes clinically relevant as the muscle can be mis-interpreted as a pathological mass. Routine dissection was performed in a 68-year-old male and a 65-year-old female donated cadavers in the pectoral region. Gross anatomical features were meticulously noted, photographed and measurements were recorded with digital Vernier callipers. In the male cadaver, a long, slender, flat bi-tendinous sternalis was found, and in the female cadaver, tripartite sternalis possessing three distinct bellies was observed. Both the sternalis was right sided and were supplied by 2nd, 3rd and 4th intercostal nerves. Single bellied and tripartite sternalis are rare and they need to be recognized in the diagnostic images and during surgeries to avoid confusion.

Pronator teres syndrome is characterized by compression of the median nerve, leading to dysfunction of the affected limb. Median nerve entrapment causes paresthesia, changes in sensitivity, and loss of strength in the fingers, in addition to causing loss of hand dexterity. The diagnosis of pronator teres syndrome is complicated, due to its similarity with other neuropathies of the median nerve. So, it is important to emphasize the need for a physical examination together with imaging tests, especially ultrasound, for its correct diagnosis. We report the case of a 28-year-old woman who complained of tingling for ten years in the proximal third of the left forearm at rest that worsens on exertion and weakness if not moving. On physical examination, she has no limitation of movement but refers to a feeling of weakness and numbness in his forearm. Ultrasonography demonstrates compression of the median nerve between the ulnar and humeral heads of the pronator teres muscle, a finding confirmed by magnetic resonance imaging and electroneuromyography. The patient was treated with physiotherapy presenting improvement of symptoms after 45 days.

Eccrine hidrocystomas are rare, benign cystic lesions that usually affect the scalp, cheeks, and eyelids. They are thought to originate from the sweat glands. These lesions can be single or many in nature and frequently worsen in the summer from increased perspiration. They are caused by dilated ducts of eccrine sweat glands. Clinically, they seem like small, transparent cystic lesions that are painless, and they usually affect middle-aged or older people. However, a histological study is necessary to make a final diagnosis. We present a case of a 35-year-old woman who had an epidermal inclusion cyst first identified as a single, painless cystic growth on her right lower eyelid.

In the clinical evaluation of upper extremity embolism cases, the anamnesis should focus on identifying potential triggering risk factors. The physical examination may reveal sensory deficits, aiding in the determination of ischemia stages. Imaging diagnosis is crucial, with computed tomography (CT) angiography being the preferred examination due to its ability to provide detailed information about arterial anatomy across multiple planes and clear visualization of adjacent structures. Compared to magnetic resonance imaging angiography, CT angiography offers faster results with minimal distortion, despite the exposure to radiation and contrast use. Doppler ultrasonography is another valuable tool in suspected arterial thromboembolism cases, particularly in emergency settings. It offers advantages over CT angiography as it is non-invasive, cost-effective, and does not involve radiation or contrast administration. We present the case of a 68-year-old man who reported a nodule in the medial region of his right thumb for three months. Initially, he experienced significant local pain and limited movement, which gradually improved over time with the use of analgesic medication. Ultrasonography revealed thrombosis in the princeps pollicis artery, and the patient commenced treatment with acetylsalicylic acid. After four months, the patient reported a marked reduction in the nodule size along with pain improvement.

Pleuroparenchymal fibroelastosis (PPFE) is a rare fibrotic lung disease with a poor prognosis. Some patients with PPFE have prominent lesions in one upper lobe. Due to the unilateral nature of lesions, similarities between some patients of PPFE and unilateral upper field pulmonary fibrosis (unilateral upper-PF) have been indicated. A 55-year-old man was referred to our hospital with PPFE, which had developed dyspnea 9 months previously. He had undergone resection of renal cancer 64 months prior to the onset of PPFE. He was administered the antifibrotic drug nintedanib, but passed away due to respiratory failure 43 months after the onset. What were impressive points in the clinical course of this PPFE patient was the similarity to unilateral upper-PF, including his medical history, and the poor prognosis. Although very rare, we do believe that the information on medical history and progression in this patient might provide suggestion into the treatment of future patients with a similar trajectory.
Infective endocarditis (IE) is a life-threatening disease, with its mortality rate varying depending on the infectious agent. Streptococci are among the most common causes of infective endocarditis. However, Streptococcus vestibularis has rarely been associated with human infections, typically affecting patients with underlying conditions such as immunosuppressive diseases, valve replacement, rheumatic heart disease, and hemodialysis. We present the case of a 26-year-old man who presented with fever, unanticipated weight loss, and fatigue. Although no typical risk factors for infective endocarditis were identified at admission, transesophageal echocardiography revealed a bicuspid aortic valve with calcification, paravalvular aortic abscess formation, and vegetations on the anterior leaflet of the mitral valve. Blood cultures grew S. vestibularis, which was initially sensitive to benzylpenicillin but developed emergent resistance on the third day of the antibiotic treatment. Subsequently, ceftriaxone therapy was initiated, and blood cultures became sterile on day 10. The patient eventually underwent aortic valve replacement. We report the first known case of native aortic and mitral valve endocarditis caused by S. vestibularis, accompanied by a paravalvular abscess around the native aortic valve, in a patient who had no typical risk factors for infective endocarditis, except for a bicuspid aortic valve.

Temporomandibular disorders (TMDs) are conditions with multifactorial etiology and complex treatment. Among the non-invasive therapeutic possibilities for these conditions is the Front Plateau, a partial anterior plate made from colourless self-curing acrylic resin. It is a simple procedure that can be carried out in a single clinical section promoting muscle relaxation to reduce symptoms associated with TMDs. This study aims to report a prospective, consecutive, single-centric case series to evaluate the Front Plateau's effectiveness in patients with temporomandibular disorders. A questionnaire adapted from the Research Diagnostic Criteria for TMDs was used and 4 patients were treated with the Front Plateau plaque. Patients were monitored after 5 and 9 months, respectively, after starting to use the Front Plateau. Of the 4 cases listed, 2 showed significant improvement in initial signs and symptoms. Front Plateau may be a favourable treatment option for patients with TMD, if the guidelines are followed. Clinical trials on this modality should seek to minimize possible biases and limitations associated with the design of this type of research.

Iliac crest is common site for harvesting bone grafts. Morphometry of iliac crest is of vital importance in orthopedic surgery. Measurements were done on male (n=85) and female (n=85) hip bones. Length of iliac crest, thickness of iliac crest and ilium were measured. Thickness was measured at pre-defined points on crest and ilium 2 cm apart starting from anterior superior iliac spine (ASIS). Ilium was measured at a depth of 2.5 cm from crest. Statistical analysis was done. Iliac crests were longer in male bones. Ventral iliac crest was thickest at 6 cm from ASIS in both sexes. While iliac crest bore minimum thickness at 12 cm and 10 cm from ASIS in male and female bones respectively, however at 2.5 cm below iliac crest surface ilium was thickest at 4 cm from ASIS and at ASIS in male and female bones respectively. In case of male bones, dorsal part of iliac crest was thickest at 2.15 ± 1.29 cm from posterior superior iliac spine (PSIS) while in females it was at 1.78 ± 1.31 cm from PSIS. In dorsal part of ilium, it was observed at 2.31 ± 1.47 cm and 1.9 ± 1.79 cm from PSIS for male and female bones respectively. This study provided detailed variable morphometry and significant sexual dimorphism observed in iliac crest and ilium. Thickest safe zones in both sexes are a useful guide for harvesting appropriate bone grafts.
