Despite the wide use of laparoscopy for liver resection, laparoscopic caudate lobe resections(L-CLR) remain technically challenging, only attempted by experts in the field. The primary objective of this study was to determine the safety and compare the perioperative outcomes of L-CLR with O-CLR based on our single institution experience in a 12 propensity score-matched controlled study based on our single institution experience.

Between 2004 and 2020, 67 consecutive patients who underwent CLR at Singapore General Hospital were identified. Propensity score matching (PSM) of laparoscopic versus open caudate lobe resections(O-CLR) was performed in a 12 ratio with no replacements using nearest neighbour matching method.

L-CLR was associated with a significantly decreased median blood loss (150 mL versus 500 mL, P=0.001) and a decreased median post-operative stay (3 days versus 7.5 days, P=<0.01) in the unmatched cohorts. After 12 propensity score matching, these results were again demonstrated with a significantly lower blood loss (150 mL versus 400 mL, P=0.016) and a shorter postoperative stay (3 days versus 7 days, P=<0.01) in favour of L-CLR. 30-day readmission and major morbidity (Clavien-Dindo grade > 2) rates were all in favour of L-CLR as well but could not reach statistical significance.

L-CLR can be safely performed by experienced surgeons. It is associated with decreased blood loss and shorter perioperative stay compared to O-CLR.

We investigated longitudinal changes in circulating CD4⁺ and CD8⁺ Tcells positive for programed cell death protein-1 (PD-1) and in other subsets of CD4⁺ Tcells in untreated hyperthyroid patients with Graves' disease after treatment with methimazole (MMI).

The study included 18 untreated hyperthyroid patients with Graves' disease and 18 age-matched controls. Before and after 12-week treatment with MMI, we used flow cytometry to measure circulating PD-1⁺ D4⁺ and PD-1⁺ CD8+ Tcells and subsets of CD4⁺ Tcells in peripheral blood, as well as serum levels of chemokines related to T-helper type 1 (Th-1) and Th-2 cells.

At baseline, the percentage of CD4⁺ and CD8⁺ Tcells expressing PD-1 was significantly higher in patients than in age-matched controls. Serum levels of chemokines related to Th-1 and Th-2 also were higher in patients. Twelve weeks after initiation of MMI, the percentage of CD4⁺ Tcells expressing PD-1 was significantly lower than at baseline, but no such change was seen in CD8⁺ Tcells. Furthermore, the percentage of Th-1 cells among CD4⁺ Tcells and the serum levels of soluble CD26/dipeptidyl peptidase-4, a surface marker of Th-1 cells, also were significantly lower than at baseline.

The expression of PD-1 on circulating CD4⁺ and CD8⁺ Tcells is increased in hyperthyroid patients with active Graves' disease. MMI significantly decreases levels of circulating PD-1⁺ CD4⁺ Tcells, suggesting that PD-1⁺ Tlymphocytes may be associated with the pathogenesis of Graves' disease.

T lymphocytes may be associated with the pathogenesis of Graves' disease.An emerging outbreak of monkeypox infection is quickly spreading worldwide, being currently reported in more than 30 countries, with slightly less than 1000 cases. In the present preliminary report, we collected and synthesized early data concerning epidemiological trends and clinical features of the ongoing outbreak and we compared them with those of previous outbreaks. Data were pooled from six clusters in Italy, Australia, the Czech Republic, Portugal, and the United Kingdom, totaling 124 cases (for 35 of which it was possible to retrieve detailed information). The ongoing epidemic differs from previous outbreaks in terms of age (54.29% of individuals in their thirties), sex/gender (most cases being males), risk factors, and transmission route, with sexual transmission being highly likely. Also, the clinical presentation is atypical and unusual, being characterized by anogenital lesions and rashes that relatively spare the face and extremities. The most prevalent sign/symptom reported was fever (in 54.29% of cases) followed by inguinal lymphadenopathy (45.71%) and exanthema (40.00%). Asthenia, fatigue, and headache were described in 22.86% and 25.71% of the subjects, respectively. Myalgia was present in 17.14% of the cases. Both genital and anal lesions (ulcers and vesicles) were reported in 31.43% of the cases. Finally, cervical lymphadenopathy was described in 11.43% of the sample, while the least commonly reported symptoms were diarrhea and axillary lymphadenopathy (5.71% of the case series for both symptoms). Some preliminary risk factors can be identified (being a young male, having sex with other men, engaging in risky behaviors and activities, including condomless sex, human immunodeficiency virus positivity (54.29% of the sample analyzed), and a story of previous sexually transmitted infections, including syphilis). On the other hand, being fully virally suppressed and undetectable may protect against a more severe infectious course. However, further research in the field is urgently needed.

Mucosal immunoglobulin comprises mainly secretory immunoglobulin A (SIgA) which mainly participates in the intestinal mucosal pathogenspecific immune response. Immunoglobulin G (IgG) is another common immunoglobulin. Bactrian camels' gastrointestinal mucosal tissue has a special mucosal immune system. However, the distribution characteristics of these two antibody-secreting cells (ASCs) in Bactrian camel's large intestine mucosal immunity system remain largely unknown. This study was aimed to describe the distribution characteristics and density of SIgA and IgG ASCs in the mucosal immunity tissues of Bactrian camel large intestine.

Tissue samples were collected from different parts of the large intestines of 10 healthy adult Chinese Alashan Bactrian camels. Immunohistochemistry technology was used to determine the distribution of SIgA and IgG ASCs in the large intestine samples and the image-Pro Plus 6.0 was employed to calculate their densities.

SIgA and IgG ASCs were distributed in lamina propria of t mucosal immunity effector sites. These distribution characteristics provide evidence to support that SIgA and IgG supply effective protection and maintain homeostasis in the large intestinal mucosa.The use of human cadavers is beneficial in teaching gross human anatomy, training, and development in medicine. Fresh-frozen cadavers initially exhibit natural color, tenderness, and flexibility. They also present innumerable difficulties, including the requirement of freezers for storage and a few weeks' work time because of fast decay. The risk of infection is also significant. A possible choice for fresh-frozen cadavers is embalmed cadavers. The requested characteristic needed for successful embalming is acceptable long-term structural preservation of organs and tissues with minimal deformity and prevention of outward aspects. Scientists are trying to develop an ideal embalming solution to preserve the human body. Such a solution renders the flexibility of internal organs, preventing dryness, and reducing fungal or bacterial growth. Cadavers should be in a condition comparable to that of an unembalmed cadaver, and the chemicals used in the solution should not be harmful to persons during manipulation. selleck chemicals llc The promising results have been obtained by the use of different embalming techniques by many faculties of medicine as a tool to enhance the teaching of anatomy to students.

The petrosal artery supplies several structures at the skull base and is often the focus of various neurointerventional procedures. Therefore, knowledge of its anatomy and variations is important to surgeons and interventionalists.

Twenty latex injected cadaveric heads (40 sides) underwent microsurgical dissection of the petrosal artery. Documentation of the course of the artery and its branches were made. Measurements of the petrosal artery's length and diameter were performed using microcalipers.

A petrosal artery was identified on all sides. The mean length and diameter of the artery within the middle cranial fossa was 2.4 cm and 0.38 mm, respectively. Branches included the following dural, ganglionic, V3 branches, branches extending through the foramen ovale, branches directly to the greater petrosal and lesser petrosal nerves, branches to the floor of the hiatus of the greater and lesser petrosal nerves, branch to the arcuate eminence, and superior tympanic artery. No statistically significant differences were noted between male and female specimens, but right-sided petrosal arteries were in general, larger in diameter than left sides.

A thorough anatomical knowledge of the petrosal artery and to its relationship to the facial nerve and other neurovascular structures is necessary to facilitate effective endovascular treatment and to preclude facial nerve complications.

The microanatomy of the central myelin portion and transitional zone of several cranial nerves including trigeminal, facial, vestibulocochlear, glossopharyngeal, and vagus nerves have been clearly demonstrated to provide information for neurovascular compression syndrome such as trigeminal neuralgia and hemifacial spasm. However, the study of oculomotor and abducens nerve is limited.

Oculomotor and abducens nerves were harvested with a portion of brainstem and embeded in paraffin. Longitudinal and serial sections from ten of each cranial nerve were stained and a photomicrograph was taken to make the following observations and measurements 1) patterns of central myelin portion, 2) length of central myelin portion, and 3) depth of central myelin-peripheral myelin transitional zone.

For oculomotor nerve, the longest central myelin bundle was always seen on the first nerve bundle and that the length of central myelin decreased gradually. For abducens nerve, morphological patterns were classified into 4 types based on number of nerve rootlets emerging from the brainstem and number of nerve bundles in each rootlet. Length of central myelin portion was between 0.36-6.10 mm (2.75+0.83 mm) and 0.13-5.01 mm (1.66+1.39 mm) for oculomotor and abducens nerves, respectively. The oculomotor nerve transitional zone depth was 0.07-058 mm (0.23+0.07 mm), while for abducens nerve, depth was 0.05-0.40mm (0.16+0.07 mm). Positive weak correlations between central myelin and depth of TZ were found in oculomotor nerve (r +0.310, p<0.05) and abducens nerves (r +0.413, p<0.05).

Detailed microanatomy of the central myelin and transitional zone might be beneficial for locating the site of compression in neurovascular conflicts at oculomotor and abducens nerves.
