Diagnostic Utility of Minor Salivary Gland Biopsy for Primary Sjögren Syndrome in Patients With Negative Anti-SSA Antibodies.

BACKGROUND: Sjögren syndrome is a systemic autoimmune disease characterized by lacrimal and salivary gland inflammation resulting in dry eyes and mouth. Although it is a common disease, diagnosis can be challenging due to its heterogeneous presentation. A positive minor salivary gland biopsy is mandatory to fulfill the 2016 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria for primary Sjögren syndrome in patients who are seronegative for anti-SSA/Ro antibodies. The objective of our study was to evaluate the validity of minor salivary gland biopsy for patients who are SSA antibody-negative yet are suspected of having primary Sjögren syndrome because of compelling symptoms. METHODS: We conducted a retrospective chart review of adult patients with a negative anti-SSA antibody test who underwent minor salivary gland biopsy to assess suspected Sjögren syndrome at Henry Ford Rheumatology Clinics between January 2005 and December 2019. Patient characteristics and clinical features are described. Sensitivity, specificity, positive predictive value, and negative predictive value are assessed. RESULTS: A total of 47 patients were included: 46 (97.9%) females and one (2.1%) male. The mean age was 57.2 ± 13.8 years. There were 14 (29.8%) patients who had a positive minor salivary gland biopsy result and 15 (31.9%) patients who had a final diagnosis of Sjögren syndrome. Minor salivary gland biopsy had 93.3% sensitivity (95% confidence interval (CI): 68%-99.8%), 100% specificity (95% CI: 89.1%-100%), 100% positive predictive value (95% CI: 76.8%-100%), and 97% negative predictive value (95% CI: 84.2%-99.9%). CONCLUSION: The diagnostic value of minor salivary gland biopsy is high for patients who do not have anti-SSA antibodies yet are suspected of having Sjögren syndrome. The results of the study support the consideration of routine minor salivary gland biopsy for identifying Sjögren syndrome in these patients.

Work of Eels Setting a Dilemma for Forensic Pathologist: A Case Report.

ABSTRACT: After the death of an individual, the body may be affected by various natural processes, including the effects of environmental factors and predation by micro-organisms and macro-organisms, which can produce a variety of artifacts. These artifacts can then pose a challenge to forensic personnel, such as whether such activity was antemortem or postmortem in nature and, if antemortem, whether such animal activities contributed to the death of an individual. This case report is a rare example of an interesting postmortem artifact of the presence of moray eels within a corpse. To the best of our knowledge, this is the first reported case of such a finding.

Clinical profile and response to first-line ARV in HIV patients from Eastern UP and Bihar: a retrospective study.

BACKGROUND AND OBJECTIVES: Spectrum of infections in Human Immunodeficiency Virus (HIV) infected patient from Eastern UP and Bihar has not been systemically evaluated. This study was conducted with the following objectives; a) explore the spectrum of clinical conditions associated with HIV disease, b)the difference between clinical and investigatory parameters in those patients who presented with infection from those who present without infection and c) to evaluate the effect of anti-retroviral (ARV) therapy. METHODS: 1248 subjects who fulfilled the inclusion criteria were enrolled for the study from May 2007 to November 2008. Patients were evaluated for their baseline characteristics along with CD4 count and followed up for at least for 6 months after initiation of ARV (6-24 months). RESULT AND INTERPRETATION: In this retrospective study, tuberculosis (58.96%) was the commonest infection followed by chronic diarrhoea (26.56%) and various skin infections. Males had significantly higher incidence (p value < .001) of infection as compared to females. There was a significant difference between the patients who presented with infection from those who presented without infection for their baseline weight (42.3 vs 45.42), haemoglobin (9.06 vs 9.91), mean CD4 count at baseline (107.38 vs 128.38/microL) and CD4 count after 6 month of therapy (298.09 vs 322.98/microL). Mortality was also significantly high (p value < 0.05) in those who presented with infection (19.95% vs 15.1%), although there was no difference between these two groups on their improvement in CD4 count from baseline after 6 months of therapy. CONCLUSION: Among the spectrum of infection in HIV patient from North East part of India, tuberculosis was commonest, followed by skin infections and chronic diarrhoea. Patients who presented with infection at the time of initial presentation had a low haemoglobin, body weight and CD4 count and had high initial mortality but if they survived they show similar response to ARV therapy as patients who presented without infection.

Effect of bone marrow-derived mononuclear cells on nerve regeneration in the transection model of the rat sciatic nerve.

Bone marrow-derived stem cells enhance the rate of regeneration and clinical improvement in nerve injury, spinal cord injury and brain infarction. Recent experiments in rat spinal cord demyelination showed that remyelination was specific to intravenous delivery of the bone marrow-derived mononuclear cell (BM-MNC) fraction, although the specific role of this fraction in peripheral nerve regeneration has not been examined. Therefore we evaluated the role of BM-MNCs in peripheral nerve regeneration in the rat sciatic nerve transection model. After anesthesia, the right sciatic nerve of 20 adult-male Wistar rats was transected under an operating microscope. In the test group, the cut ends of the nerve were approximated with two epineural microsutures, the gap was filled with rat BM-MNCs and the approximated nerve ends were covered with fibrin glue. In the control group, the transected nerve ends were repaired with two epineural microsutures and fibrin sealant only. Histological assessment of the nerve was performed 30 days and 60 days after the operation and regenerative changes were compared between the two groups. The recovery after nerve anastamosis was far better in the test group at both 30 days and 60 days. There was a statistically significant difference in axonal regeneration, remyelination and myelin thickness at sites 5mm and 10mm from the site of repair of the nerve. Schwann cell proliferation and degenerative changes were more prevalent in the controls. This study demonstrates that local delivery of BM-MNCs (which can be isolated easily from bone marrow aspirates) into injured peripheral nerve increases the rate and degree of nerve regeneration. The present study highlights the role of BM-MNCs in peripheral nerve regeneration.

Endoscopic management of intraventricular neurocysticercosis.

Surgical management is the only option for patients presenting with acute hydrocephalus caused by intraventricular neurocysticercosis. Although various modalities have been described, endoscopic excision is becoming increasingly popular. The outcomes for 22 patients with intraventricular neurocysticercal cysts with hydrocephalus managed endoscopically are presented. Complete excision of cysts (fourth ventricle, 14; lateral ventricle, 4; third ventricle, 3; both lateral and third ventricles, 1) was performed in all patients. Internal procedures for cerebrospinal fluid diversion were performed in 20 patients. There were minimal perioperative complications, all patients were relieved of raised intracranial pressure and no patient has required shunting to date. Mean follow-up duration was 20.7 months. Follow-up imaging showed the absence of residual cysts and resolution of hydrocephalus in all patients.

Transventricular, transaqueductal scope-in-scope endoscopic excision of fourth ventricular neurocysticercosis: a series of 13 cases and a review.

OBJECT: Neurocysticercosis (NCC) is the most common parasitic infestation of the central nervous system worldwide. In patients presenting with acute hydrocephalus due to intraventricular NCC, surgery is the only option. Still, there is no consensus regarding the optimal surgical strategy, although neuroendoscopic excision is a promising method. However, the literature regarding the use of this modality in fourth ventricular NCC is scarce. The authors describe a series of patients with fourth ventricular NCC treated endoscopically. METHODS: The clinical records of 13 patients with fourth ventricular NCC who had presented with hydrocephalus were retrospectively analyzed. A fourth ventricular cyst was completely excised in all patients by using a transventricular, transaqueductal "scope-in-scope" endoscopic technique. Twelve endoscopic third ventriculostomies and 1 septostomy had been performed. RESULTS: Shunt placement was avoided in all patients. There were minimal peri- and postoperative complications. The mean duration of follow-up was 22.3 months (range 3-41 months). All patients had an improved clinical outcome. Follow-up neuroimaging revealed no residual lesion and a decreased ventricle size in all patients. CONCLUSIONS: The present series of patients with fourth ventricular NCC is the largest in the existing English-language medical literature. Endoscopic fourth ventricular cysticercal cyst excision along with internal cerebrospinal fluid diversion via endoscopic third ventriculostomy is an effective alternative to open microneurosurgical procedures and avoids shunt placement and its related complications.

Endoscopic excision of intraventricular neurocysticercosis in children: a series of six cases and review.

OBJECTS: Neurocysticercosis (NCC) affects both adults and children, but it is uncommon in childhood. The clinical presentation and management of intraventricular neurocysticercosis (IVNCC) in children has not been described adequately. We, therefore, present our series of six children with IVNCC managed by endoscopic excision. MATERIALS AND METHODS: A retrospective analysis of six children with IVNCC was performed. The endoscopic technique practiced is described. Complete excision of the intraventricular cyst was performed in all patients. Simultaneously, five endoscopic third ventriculostomies, one septostomy, and one foramenotomy were performed. There were no perioperative and postoperative complications. Mean follow-up duration was 24.8 months. Clinical improvement was seen in all children, and none required shunting. Follow-up radiology showed no residual lesion and decreased ventricle size in all patients. CONCLUSION: Endoscopic IVNCC cyst excision along with internal CSF diversion is a safe and effective option and avoids shunt and its related complications in these children.

Spontaneous transmural migration of surgical sponges.

Postoperative retained surgical sponges or other foreign bodies are usually underreported. Radio-opaque materials are usually detected on follow-up radiological investigations, but radiolucent materials such as sponges create diagnostic problems and clinically mimic various abdominal pathologies. Introduction of spiral computed tomography, magnetic resonance imaging and dedicated ultrasonography has enabled clinicians to find these foreign bodies at the earliest opportunity to avoid disastrous complications. Spontaneous transmural migration and expulsion per rectum of more than one sponge without sequelae is also possible. We report one such interesting case.
