We report a case of a rare sporadic Vestibular Schwannoma of a 9-month-old girl who had a right-sided lower motor type facial nerve palsy. The patient was initially diagnosed with Bell’s palsy and received steroid treatment accordingly, two months later the patient’s condition deteriorated, and further evaluation of CT and MRI brain was conducted that showed a mass lesion in the posterior fossa causing compression on the facial nerve. Misdiagnosis of facial nerve paralysis is common among children due to multiple related etiologies and varying rates of incidence in comparison to adults. The authors hope to address this issue in this report. Background: Facial nerve paralysis has been a matter of concern for many researchers to understand its nature, causes and presentation according to different age groups. In adults, Bell’s palsy (BP), the idiopathic form of facial nerve paralysis, is more common compared to children where most cases are due to secondary etiologies. Therefore, pediatricians are in an important position to identify these patients early in order to launch the most effective diagnostic and treatment approaches.

Failure detection is an essential task in industrial systems for preventing costly downtime and ensuring the seamlessoperation of the system. Current industrial processes are getting smarter with the emergence of Industry ***, various modernized industrial processes have been equipped with quite a few sensors to collectprocess-based data to find faults arising or prevailing in processes along with monitoring the status of *** diagnosis of rotating machines serves a main role in the engineering field and industrial production. Dueto the disadvantages of existing fault, diagnosis approaches, which greatly depend on professional experienceand human knowledge, intellectual fault diagnosis based on deep learning (DL) has attracted the researcher’sinterest. DL reaches the desired fault classification and automatic feature learning. Therefore, this article designs a Gradient Optimizer Algorithm with Hybrid Deep Learning-based Failure Detection and Classification (GOAHDLFDC)in the industrial environment. The presented GOAHDL-FDC technique initially applies continuous wavelettransform (CWT) for preprocessing the actual vibrational signals of the rotating machinery. Next, the residualnetwork (ResNet18) model was exploited for the extraction of features from the vibration signals which are thenfed into theHDLmodel for automated fault detection. Finally, theGOA-based hyperparameter tuning is performedtoadjust the parameter valuesof theHDLmodel *** experimental result analysis of the GOAHDL-FD Calgorithm takes place using a series of simulations and the experimentation outcomes highlight the better resultsof the GOAHDL-FDC technique under different aspects.

AIM： To assess the use of topical negative pressure （TNP） in the management of severe peritonitis. METHODS： This is a four-year prospective analysis from January 2005 to December 2008 of 20 patients requiring TNP following laparotomy for severe peritonitis. RESULTS： There were 11 males with an average age of （59.3 ± 3.95） years. Nine had a perforated viscus, five had anastomotic leaks, three had iatrogenic bowel injury, and a further three had severe pelvic inflammatory disease. TNP and the VAC Abdominal Dressing System were initially used. These were changed every two to three days. Abdominal closure was achieved in 15/20 patients within 4.53 ± 1.64 d. One patient required relaparotomy due to residual sepsis. Two patients with severe faecal peritonitis due to perforated diverticular disease received primary anastomosis at second look laparotomy, as sepsis and their general condition improved. In the remaining 5/20 cases, the abdomen was lee open due to bowel oedema and or abdominal wall oedema. Dressing was switched to TNP and VAC GranuFoam . Three of the five patients returned a few months later for abdominal wall reconstruction and restoration of intestinal continuity. Two patients developed intestinal fistulae. All 20 patients survived.CONCLUSION： The use of TNP is safe. Further studies are needed to assess its value in managing these difficult cases.

Squamous cell carcinoma of the gallbladder is rare and accounts for about 12.7% of all cases of gallbladder cancer. Pure squamous cell carcinoma is even less common with a reported incidence of 3.3%. We present a case of 72 year-old African-American woman with decreased appetite, fatigue, and weight loss associated with intermittent right upper quadrant pain for two months. Computed tomography of the abdomen revealed a mass in the gallbladder and the hepatic flexure of the colon with involvement of adjacent small bowel. On exploratory laparotomy, a mass at the dome of the gallbladder was found with local invasion of the hepatic flexure, and the proximal transverse colon. There was no obvious involvement of the duodenum, common bile duct, or the extra-hepatic biliary tree. An extended right hemicolectomy, distal small bowel resection, cholecystectomy, a wedge resection of the liver and a feeding jejunostomy, were performed. Pathologic evaluation demonstrated well to moderately differentiated squamous cell carcinoma of gallbladder without evidence of distant metastasis. The patient improved clinically and was discharged home in good condition.

Acute gastric dilation leading to ischemia of the stomach is an underdiagnosed condition and can be potentially fatal. It can occur in various medical and surgical conditions such as post operative state, trauma, anorexia, spinal abnormalities, diabetes mellitus and electrolyte imbalance. Without proper and timely diagnosis and treatment, gastric perforation and hemorrhage can occur. In this report, we present a case of acute massive gastric dilation in a settling of type II diabetes mellitus and urosepsis. We will also present a review of literature and management options for such condition. Our report highlights the need for high index of suspicion and early intervention to avoid life threatening complications.

An empty sella occurs due to herniation of the arachnoid through an incompetent diaphragma sellae. Over time, cerebrospinal fluid (CSF) pulsations may enlarge the sella and compress the gland against the floor of the sella. Empty sella syndrome is considered as a less common entity and is usually asymptomatic and an incidental finding. However, it can be a manifestation of increased intracranial pressure and can be occasionally severe. Compression of the pituitary gland may affect function, or traction on the optic chiasm and nerves may cause visual symptoms. An empty sella may be classified as primary when this occurs in persons who have not received pituitary radiation or pituitary surgery, while an empty sella discovered following such procedures is classified as secondary empty sella. In this report, we presented a 41-year-old multiparous patient who presented to us with symptoms of headache and left sided hemi-sensory disturbance. Examination was unrevealing except for the fact that she was obese. On evaluation, she was detected to have impaired blood sugars, dyslipidemia and vitamin insufficiency. MRI brain revealed presence of Empty Sella. Further hormonal analysis was normal. She was treated conservatively and regular follow-up was advised.
