Schizophrenia: Antipsychotics and drug growth.
Negative symptoms and cognitive deficits are difficult-to-treat symptoms of schizophrenia. In this single blind randomized controlled study, we compared change in social cognitive performance in persons with Schizophrenia (PWS) (as per DSM-5), after 6 weeks of yoga intervention with a waitlist control group. We also examined changes in putative Mirror Neuron System (MNS) activity measured by Transcranial Magnetic Stimulation (TMS) in a subset of sample (n = 30). 51 PWS stabilized on antipsychotic medication for at least 6 weeks, were assigned to add-on yoga therapy (YT) (n = 26) or waitlist (WL) (n = 25). Subjects in the YT group received add-on yoga therapy (20 sessions in 6 weeks). Both the groups continued their standard treatment and were assessed at baseline and after 6 weeks for social cognition, clinical symptoms and social disability. RM-ANOVA showed significant interaction between time and group for social cognition composite score (SCCS) (F = 42.09 [1,44], P less then 0.001); negative symptoms (SANS) (F = 74.91 [1,45], P less then 0.001); positive symptoms (SAPS) (F = 16.05 [1,45], P less then 0.001) and social disability (GSDS) (F = 29.91 [1,46], P less then 0.001). MNS activity had increased after 6 weeks in both groups but not of statistical significance. This study demonstrates that 6 weeks of add-on yoga therapy could improve social cognition in PWS compared to waitlist control subjects. However, the change in social cognition was not associated with a change in the putative MNS-activity. It necessiatates further studies to investigate the mechanistic processes of yoga and replicate these observations in a larger sample.We described a mode of catalytic activation that accomplished the α-alkylation of N-Boc saturated heterocycles with DNA-linked acrylamide via photoredox-mediated hydrogen atom transfer (HAT) catalysis. This C(sp3)-C(sp3) bond formation reaction tolerated five-, six- and seven-membered cyclic substrates, substantially streamline synthetic efforts to functionalize the α-position of heterocycles with native CH functional handle. This photoredox catalyzed CH functionalization proceeded in mild DNA-compatible condition, and suited for the construction of DNA-encoded libraries.
Renal vascular complications are a significant cause of morbidity in living donor renal transplantation. Among renal vascular complications, transplant renal artery stenosis (TRAS) secondary to mechanical kinking is a rare but important cause of early graft dysfunction. Identifying this phenomenon and correcting the underlying cause is critical to graft viability in the post-operative period. This case illustrates the importance of balloon angioplasty in identifying this complication and prompting surgical correction.

We describe the case of a 67-year-old male who received a right-sided living donor kidney graft for Stage IV Chronic Kidney Disease secondary to biopsy proven Ig-A nephropathy. In the post-operative course, serum creatinine remained elevated and Doppler showed low-normal vascular flow velocities. Liraglutide Renal angiogram indicated transplant renal artery stenosis secondary to the rare phenomenon of mechanical kinking. Findings noted during unsuccessful angioplasty supported the diagnosis and surgicalirm the diagnosis and prompt definitive surgical repair.
A Meckel's diverticulum is a rare but known cause of an acute abdomen and can often be confused for acute appendicitis on physical examination. It is caused by an incomplete closure of the omphalomesenteric duct. It is present in 2% of the population and only 2% of those patients are symptomatic.

This is the case of a sixty-four-year-old male presented to the surgical clinic at request of his primary care physician with concern for acute appendicitis. The patient had a CT A/P with IV contrast performed two days prior to his office visit for the same pain which was non-diagnostic. The patient was taken to the operating room and found to have Meckel's Diverticulitis which was managed by laparoscopic hand-assisted small bowel resection and anastomosis. The patient had an uncomplicated postoperative course. Pathology demonstrated ulcerated gastric mucosa and pancreatic tissue.

Symptomatic Meckel's diverticulum is managed with small bowel resection versus diverticulectomy based on characteristics of the diverticulum. The most common type of ectopic tissue is gastric followed by pancreatic. It is rare to find both types of tissue together.

This case describes an unusual case of a rare acute surgical pathology with non-diagnostic imaging and labs. This case also describes an exceedingly rare histopathology of a Meckel's Diverticulum with the presence of both ectopic gastric and pancreatic tissues.

Static bone cavity (SBC) is a bone defect that develops as a result of localized pressure from tissues surrounding the mandible. It is most commonly observed in the mandibular angle of adult males caused by the submandibular gland. The condition is asymptomatic and requires no treatment. The frequency of onset is rare, especially in the anterior mandible, and SBC is extremely difficult to diagnose in children.

This report is on a case of SBC in the anterior mandible of a 10-year-old boy. The condition could not be diagnosed after panoramic radiograph and Magnetic Resonance Imaging (MRI) analyses. Computed-topography (CT) imagery revealed an oval-shaped depression 6×5×3mm in size at the lingual apex of the mandibular left lateral tooth. Diagnosing the patient was difficult and a tumor was suspected. For treatment, the tumor-like lesion was resected and the fistula in the periosteum was sutured and closed. One year later, the defect on the lingual mandibular bone had ossified and recovered.

Cerebellar ataxia, neuropathy and vestibular areflexia syndrome (CANVAS) is a rare multisystem neurodegenerative disorder. We describe our perioperative evaluation and care of a patient with CANVAS undergoing a pancreaticoduodenectomy for an ampullary adenocarcinoma, with a focus on perioperative risk stratification and optimisation, intraoperative advanced haemodynamic monitoring and the postoperative care.

A 69-year-old female with CANVAS presented with asymptomatic obstructive jaundice, icterus and abdominal pain. She had limited mobility and deconditioning due to severe generalised neuropathy. Computed tomography confirmed a resectable periampullary tumour. Her Duke Activity Status Index was 8.25 points and Edmonton Frailty Scale score was 11, confirming moderate frailty. However, the Charlson Comorbidity Index was five, indicative of a 21% estimated 10-year survival. Further risk stratification including respiratory function testing, echocardiography and cardiopulmonary exercise testing was conducted. The patient proceeded with surgery after multidisciplinary discussions with her treating medical teams.

CANVAS is a rare and challenging condition requiring careful perioperative planning and management. There is no effective treatment for CANVAS. The management approach focuses on mitigating symptoms and improving quality of life. Given that no specific guidelines for managing these patients in the perioperative period have been provided, this report highlights several critical medical issues and implications that should be considered for the successful management of these patients. We demonstrate the role of specific anaesthesia techniques and advanced haemodynamic monitoring in both preventing postoperative morbidity and optimising patient recovery.

CANVAS is a rare and challenging condition in anaesthesia requiring careful perioperative planning and management.

This report describes the long-term outcomes of Tenon's patch graft (TPG) in a corneal perforation secondary to neurotrophic keratitis and outcome of subsequent successful cataract surgery.

A 60-year gentleman presented with a corneal perforation secondary to Herpes Zoster ophthalmicus (HZO). After multiple unsuccessful attempts of cyanoacrylate tissue adhesive application over the perforation, he was referred for a corneal patch graft. Following TPG, he had a tectonically stable cornea that was managed with topical steroids and prophylactic oral Acyclovir. Sequential imaging of the cornea using high-resolution anterior segment- optical coherence tomography (HR-ASOCT) was done to monitor wound healing. Fifteen months later, he underwent uneventful cataract surgery with best-corrected visual acuity improving to 20/30 at 1-month.

Serial imaging of the site of perforation with HR-ASOCT revealed that a fluffy, oedematous TPG in the early postoperative period transitioned into a hyper-reflective, thin, and compact graft over 3-4 months. Despite the corneal thickness at the site of perforation being only 142μm, the wound had adequate tensile strength to withstand the altered anterior chamber dynamics during phacoemulsification. The resultant translucent nature of the scar provided superior media clarity and better visual outcomes.

This case demonstrates the efficacy of TPG in acute phase management of corneal perforation following HZO thereby restoring the tensile strength of the cornea, enabling it to withstand the stress of future surgeries like phacoemulsification.

Ganglioneuromas are rare benign tumors originating from neural crests and typically affect young adults. The most frequent locations are the posterior mediastinum, retroperitoneum and adrenal gland. In general, retroperitoneal ganglioneuromas are discovered incidentally or by mass effect. In the literature, the number of retroperitoneal masses reported is quite limited. We report a case of laparoscopic excision of a retroperitoneal ganglioneuroma.

The patient was a 40-year-old woman who visited a nearby clinic with anorexia and vomiting. She was referred to our hospital after the detection of an abdominal mass. Enhanced computed tomography(CT) showed a lobule mass of 107×42mm in size, with internal inhomogeneity and mild delayed enhancement on the retroperitoneal side of the left abdominal lesion. Magnetic resonance imaging(MRI) showed a mass with low intensity and partial high intensity on T2 weighted Image (T2WI). In addition, positron emission tomography CT(PET-CT) detected slight fluorodeoxyglucose (FDG) accumulation (standardized uptake value(SUV) max 3.01) in the same lesion. Based on these findings, we suspected a retroperitoneal tumor. Laparoscopic excision was performed via 5 ports. The extracted tissue was a well-defined mass of 110×70mm. The tumor in our case exceeded 10cm. The pathological diagnosis was ganglioneuroma, with no obvious malignancy.

It was suggested that adaptation of laparoscopic surgery should be considered based on the observation of organ invasion or vessel invasion and adhesion around the tumor, rather than based on the diameter of the tumor.

This approach is less invasive than conventional laparotomy methods and achieves good cosmetic outcomes. Thus, totally laparoscopic procedures should be considered more often for the treatment of retroperitoneal tumors.
