Fusarium flocciferum, causing wilt disease of chili (Capsicum annuum L.) in Northern Himalayas: A first report.

In August 2020 chili (Capsicum annuum L.) showing wilt symptoms were collected from different districts of the Kashmir: Pulwama, Srinagar, Baramulla, and Anantnag. From each district one location was selected for sample collection and a total of 23 chili isolates were isolated. The tissue bit technique was used to isolate fungus from the infected samples on potato dextrose agar (PDA) medium, purified using the single spore technique, maintained at 25°±1℃ and then stored at 4° C (Ferniah et al. 2014) . Initially cultural characteristics appeared as white colonies which gradually turned to pale white colored and attained a growth of 90 mm in 18 days of incubation at 25 ± 1°C. Microscopic observations revealed that mycelium was branched and cylindrical, 3.53-4.98 µm in width. Microconidia were ellipsoidal, hyaline, 0-1 septa werepresent, and 6-7 x 3-4 µm in size. Macroconidia were cylindrical, hyaline, 2-6 septa, measuring 20-60 x 40-45 µm in size. Molecular identification of the pathogens with ITS, TEF, and RPB2 was successfully carried out and the fungi was confirmed as Fusarium flocciferum infecting chili. Amplified PCR products were sequenced and were successfully submitted and accessioned in GenBank with accession number OM189458, OM441199, OR484037 for ITS, TEF, and RPB2 gene. To confirm Koch's postulates pathogenicity test was carried out using rhizosphere inoculation technique (Najar et al. 2011, Parihar et al. 2022). In total 7 replications for sand maize meal medium (potting mixture) was prepared by autoclaving 90 g of sand and 10 g of maize meal in 250 ml of erlenmeyer flask comprising 40 ml of distilled water. The spore suspension at 100 µl per pot was inoculated and was mixed with the sterilized potting mixture in a ratio of (2:1) and up to seven days pathogen was allowed to infect the soil (Davey and Papavizas 1962; Hami et al. 2021). Then chili seeds (cv. Kashmir long-1) were sown in infected potting mixture and grown for three weeks to allow the pathogen to infect the host plants. F. flocciferum took six weeks for appearance of symptoms in the infected potted plants. Control mock inoculation of the potting mixture was carried out using water droplets instead of spore suspension at 100 µl per pot. Seven replications were kept for both inoculated and un-inoculated / control mock pots. The plants developed initial symptoms from light green to yellowish discoloration of leaves followed by the drooping, shriveling, and ultimately leading to death. The collar region of the plant was cut vertically and observed that vascular bundles showed brownish spots and discoloration, indicating wilt as the cause of death. The pathogens were re-isolated and inoculated from all infected plants, then compared with their original pure culture inoculated first, which completely resembled based on morphological, cultural, and pathogenic characteristics. No symptoms were observed on control plants. A phylogenetic analysis was also carried out using ClustalW software that grouped the species identified by different genes into different clades. F. flocciferum has been reported earlier in pea, faba bean and bamboo (Kainthola et al. 2022; Sisic et al. 2020) . In solanaceous crops, this species have been explored as wilt pathogens for the first time from India, indicating diversifying nature of Fusarium flocciferum across various hosts including solanaceous crops.

Pellet gunfire injuries among agitated mobs in Kashmir.

BACKGROUND: Pellet gunfire injuries inflicted while controlling agitated mobs has been studied. METHODS: A total of 198 patients admitted to the Accident and Emergency Department with pellet gun injuries were studied in terms of anatomic site, severity and type of injury, treatment, and outcomes. RESULTS: 72.7% of patients were aged 16-25 years. The most common sites of injury were the extremities (47.9%), abdomen (36.3%) and chest (31.3%). 59.5% of patients were found to have minor injuries. Of the 80 patients admitted to the hospital for their injuries, 43 (53.7%) required an operative procedure. Six deaths (3.03%) were observed. CONCLUSION: While the pellet wound itself may seem trivial, if not appreciated for the potential for tissue disruption and injuries to the head, chest, and abdomen, there can be catastrophic results. Patients should be evaluated and managed in the same way as those sustaining bullet injuries.:

Papillary carcinoma thyroid with metastasis to ectopic cervical thymus.

Papillary carcinoma of thyroid is the most common type of thyroid neoplasm which is usually confined to the thyroid and tends to metastasize to regional lymph nodes. Distant metastasis occur in up to 15% of cases. Thymic metastasis from any malignant carcinoma is extremely rare with only four cases reported in medical literature. We report a case of papillary carcinoma of thyroid metastasizing to ectopic cervical thymus which has not been previously reported.

Helicobacter pylori Subdues Cytokine Signaling to Alter Mucosal Inflammation via Hypermethylation of Suppressor of Cytokine Signaling 1 Gene During Gastric Carcinogenesis.

Helicobacter pylori infection has been associated with the onset of gastric mucosal inflammation and is known to perturb the balance between T-regulatory (Treg) and T-helper 17 (Th17) cells which causes a spurt of interleukin 17 (IL17) and transforming growth factor-ß (TGF-ß) from Th17 and Treg cells within the gastric milieu. IL17 instigates a surge of interleukin 6 (IL6) from T-helper 1 (Th1) and T-helper 2 (Th2) cells. Further, H. pylori infection is known to stimulate the atypical DNA methylation in gastric mucosa. However, the precise role of cytokine signaling in induction of epigenetic modifications during gastric carcinogenesis is vaguely understood. In this study, patient samples from were examined using real-time polymerase chain reaction (qPCR), PCR, methylation-specific (MS)-PCR, and enzyme-linked immunosorbent assays. We found that H. pylori infection augments the production of interleukin 10 (IL10), IL6, and TGF-ß in the gastric milieu and systemic circulation. Together with the IL6/IL10 mediated hyperactivation of the JAK/STAT pathway, H. pylori infection causes the inactivation of suppressor of cytokine signaling 1 (SOCS1) gene through the hypermethylation of the promoter region. This study signifies that H. pylori-mediated epigenetic silencing of SOCS1 in concert with inflammatory cytokines miffs hyperactivation of the JAK/STAT cascade during gastric carcinogenesis.

Significant Pattern of Promoter Hypermethylation of UNC5C Gene in Colorectal Cancer and Its Implication in Late Stage Disease

Background:The development of Colorectal Cancer (CRC) is a complex multistep process involving an accumulation of multiple genetic and epigenetic alterations. Epigenetic modifications, particularly DNA methylation in selected gene are recognized as common molecular alterations in human tumors. Netrin-1 receptors are aberrantly methylated in primary colorectal cancer. Epigenetic alterations in the netrin-1 receptors have been found to be related with the malignant potential of CRC. Purpose: In the present study, we evaluated the role of promoter hypermethylation of UNC5C gene (one of the netrin-1 receptors) in colorectal cancer patients of Kashmiri population (North India). Hypermethylation in tumour tissue was detected by Methylation- Specific Polymerase Chain Reaction (MS-PCR). Results: UNC5C promoter hypermethylation was significantly found to be associated with colorectal cancer cases where frequency was 62% (31 of 50) and 38% (19 of 50) patients were unmethylated (p<0.0001).UNC5C methylation was significantly higher in CRCs with a frequency of 62% than 10% in corresponding normal mucosa of (p<0.0001). Further, UNC5C hypermethylation was found to be significantly associated with stage-III/IV as compared to stage I/II with a frequency of 75.8% and 42.8% respectively(p>0.05). Conclusion: We conclude that UNC5C hypermethylation is implicated in CRC which plays a role in its tumorigenesis and may predict the late stage disease.

Drainage vs no drainage in secondary peritonitis with sepsis following complicated appendicitis in adults in the modern era of antibiotics.

AIM: To compare the profile of postoperative outcome in secondary peritonitis with sepsis due to complicated appendicitis in two cohorts (drainage vs no-drainage) after appendicectomy in adults in the modern era of effective antibiotics. METHODS: A retrospective review of all adult patients who were operated for secondary peritonitis with sepsis due to complicated appendicitis was carried out. Total of 209 patients were identified from May 2005 to April 2009 with operative findings of gangrenous or perforated appendix. The patients were divided into two cohorts, those where prophylactic drainage was established (n = 88) and those where no drain was used (n = 121). Abdominal drain was removed once the drainage ceased or decreased (< 10-20 mL/d in closed system of drainage or when once daily dressing was minimally soaked in open system). Broad spectrum antibiotics to cover the gut flora were started in both cohorts at diagnosis and were stopped once septic features resolved. Peritoneal fluid for aerobic culture and sensitivity were routinely obtained intra operatively; however antibiotic regimens were not changed unless patient failed to respond to the antibiotics based on the institutional protocol. The co-morbidities and their influence on primary end points were noted. Immunocompromised patients, appendicitis complicated by inflammatory bowel disorder and tumors were excluded from the study. RESULTS: Disease stratification and other demographic features were comparable in both cohorts. There was zero mortality in drainage group while as one patient (0.82%) died in the non-drainage group. The median duration (in days) of hospital stay (6.5 vs 4); antibiotic use (5 vs 3.5); regular parental analgesic use (5 vs 3.5) and paralytic ileus (2.5 vs 2) was more common in the drainage group. Incidence of major wound infection in patients 14 (15.9%) vs 22 (18.18%) and residual intra-abdominal sepsis (inter loop collection/abscess) -7 (8%) vs 13 (10.74%) requiring secondary intervention was not significantly different in drainage and non-drainage cohorts respectively. One patient in the drainage cohort had faecal fistula (1.1%). CONCLUSION: The complicated appendicitis in the modern era of antibiotics does not necessitate the use of prophylactic drain placement which at times may even prove counterproductive.

Long-term results of choledochoduodenostomy in benign biliary obstruction.

AIM: To determine the long-term results of choledochodudenostomy in patients with benign billiary obstruction. METHODS: This prospective study was conducted at Sheri Kashmir Institute of Medical Sciences Srinagar Kashmir, India over a period of 10 years from January 1997 to December 2007. The total number of patients who underwent choledochoduodenostomy during this period was 270. On the basis of etiology of biliary tract obstruction, patients were divided into a calculus group, an oriental cholangiohepatitis group, a benign biliary stricture group and others. Patients were followed for a variable period of 13 mo to 15 years. RESULTS: Choledochoduodenostomy (CDD) with duo-denotomy was performend in four patients. CDD with removal of T- tube, CDD with left hepatic lobectomy and CDD with removal of intra biliary ruptured hydatid was performed in three patients each. In the remaining patients only CDD was performed. Immediate post operative complications were seen in 63 (23%) patients, while long-term complications were seen in 28 (11%) patients, which were statistically significant. Three patients died during hospitalization while four patients died in the late post-operative period. CONCLUSION: Our conclusion is that CDD is safe and produces good long term results when a permanent biliary drainage procedure is required.

Ulcerative colitis: a challenge to surgeons.

Ulcerative colitis is a chronic disease that specifically affects the mucosa of the rectum and colon. Although the etiology of this recurring inflammatory disorder remains essentially unknown, there have been significant advances in identifying the likely genetic and environmental factors that contribute to its pathogenesis. The clinical course of the disease typically manifests with remissions and exacerbations characterized by rectal bleeding and diarrhea. Since ulcerative colitis most commonly affects patients in their youth or early middle age, the disease can have serious long-term local and systemic consequences. There is no specific medical therapy that is curative. Although medical therapy can ameliorate the inflammatory process and control most symptomatic flares, it provides no definitive treatment for the disease. Proctocolectomy or total removal of the colon and rectum provides the only complete cure; however, innovative surgical alternatives have eliminated the need for a permanent ileostomy. The aim of this review is to provide a detailed account of the surgical management of ulcerative colitis.

Atypical localizations of hydatid disease: experience from a single institute.

INTRODUCTION: The hydatid disease most often involves the liver and the lungs. The disease can involve any part of the body except the hair, teeth and nails. Primary extrahepatico-pulmonary hydatid cysts are rare and only a few sporadic cases have been reported. MATERIALS AND METHODS: Two hundred and forty-four patients with hydatid cysts managed surgically from January 2005 to December 2009 were evaluated retrospectively. Fourteen (5.7%) patients had isolated involvement of the atypical sites, while six (2.4%) also had a primary involvement of liver. RESULTS: The cysts were present in gall bladder (0.4%), peritoneum (1.6%), spleen (1.6%), ovary (0.4%), subcutaneous (0.8%), seminal vesicle (0.4%), spinal (0.4%), pancreas (0.4%), kidney (0.4%), mediastinal (0.4%), muscle (0.4%), and brain (0.8%). DISCUSSION AND CONCLUSIONS: Involvement of sites other than liver and lungs by hydatid disease is rare. Symptoms are related to size, location or possible complication of the cyst. It should be strongly suspected in differential diagnosis of all abdominal cysts especially in an endemic area. Proper surgical and medical management to avoid any recurrences, and a regular follow-up, are of utmost importance to detect any late complications such as local recurrence of the disease and development of hydatidosis at the primary sites.

Primary splenic hydatidosis.

Primary extrahepatic hydatid cysts are rare, and primary splenic hydatid cysts even more so, constituting 2% to 3.5% of all hydatid cysts. We report here a case series of isolated splenic hydatid cysts. Case records of 382 adult patients of abdominal hydatid cysts were analyzed; eight of them (2%; aged 23 to 45 years, 5 women and 3 men) had primary splenic hydatid cysts. Seven patients presented with dull dragging pain in the left hypochondrium. Four patients had splenomegaly. Diagnosis was made at ultrasonography and/or contrast-enhanced computed tomography. Enzyme linked immunosorbent assay for hydatid antibodies tested positive in all patients. One patient presented with hemoperitoneum. All patients underwent splenectomy. Primary splenic hydatid cyst is rare but should be considered in patients with cystic lesions of the spleen.

Role of albendazole in the management of hydatid cyst liver.

BACKGROUND/AIM: Hydatidosis has a worldwide distribution and the liver is the most common organ involved. Hydatid cysts of the liver can be managed either by nonoperative or operative methods. Nonoperative methods include chemotherapy and percutaneous treatment. The study aimed at understanding the effect of albendazole therapy on the viability of protoscoleces and recurrence rate of hydatid disease of the liver. PATIENTS AND METHODS: The study was conducted at Sher-i-Kashmir Institute of Medical Sciences, Soura, Srinagar, Kashmir, India, over a period of 2 years from January 2002 to December 2003, with further follow-up of 5 years. The study included 72 cases in the age group of 17-66 years, comprising 39 males and 33 females. The patients were randomized into two groups of 36 patients each. In group A, patients were directly subjected to surgery, while in group B, patients were administered albendazole for 12 weeks preoperatively, followed by a further postoperative course for 12 weeks. RESULTS: Of patients who received albendazole therapy, no patient had viable cysts at the time of surgery, as compared to 94.45% of the patients who did not receive any preoperative albendazole (P<0.01). In patients who did not receive any albendazole therapy, recurrence rate was 16.66%, while no recurrence was seen in patients who received albendazole therapy (P≤0.05). CONCLUSION: We conclude that albendazole is an effective adjuvant therapy in the treatment of hydatid liver disease.

Breast gangrene.

BACKGROUND: Breast gangrene is rare in surgical practice. Gangrene of breast can be idiopathic or secondary to some causative factor. Antibiotics and debridement are used for management. Acute inflammatory infiltrate, severe necrosis of breast tissue, necrotizing arteritis, and venous thrombosis is observed on histopathology. The aim of was to study patients who had breast gangrene. METHODS: A prospective study of 10 patients who had breast gangrene over a period of 6 years were analyzed RESULTS: All the patients in the study group were female. Total of 10 patients were encountered who had breast gangrene. Six patients presented with breast gangrene on the right breast whereas four had on left breast. Out of 10 patients, three had breast abscess after teeth bite followed by gangrene, one had iatrogenic trauma by needle aspiration of erythematous area of breast under septic conditions. Four had history of application of belladonna on cutaneous breast abscess and had then gangrene. All were lactating female. Amongst the rest two were elderly, one of which was a diabetic who had gangrene of breast and had no application of belladonna. All except one had debridement under cover of broad spectrum antibiotics. Three patients had grafting to cover the raw area. CONCLUSION: Breast gangrene occurs rarely. Etiology is variable and mutifactorial. Teeth bite while lactation and the iatrogenic trauma by needle aspiration of breast abscess under unsterlised conditions could be causative. Uncontrolled diabetes can be one more causative factor for the breast gangrene. Belladonna application as a topical agent could be inciting factor. Sometimes gangrene of breast can be idiopathic. Treatment is antibiotics and debridement.

Meckel's diverticulum-Revisited.

Meckel's diverticulum is a true intestinal diverticulum that results from the failure of the vitelline duct to obliterate during the fifth week of fetal development. In about 50% cases, it contains ectopic or heterotopic tissue which can be the cause of complications. A systematic review of literature was undertaken to study the history, incidence, embryoanatomy, clinical presentation, complication and management of Meckel's diverticulum. Although Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract, it is often difficult to diagnose. It may remain asymptomatic or it may mimic disorders such as Crohn's disease, appendicitis and peptic ulcer disease.

Pyogenic liver abscess: Changing patterns in approach.

AIM: To define optimum management of the pyogenic liver abscess and assess new trends in treatment. METHODS: One hundred and sixty nine patients with pyogenic liver abscess managed at Sher-i-Kashmir Institute of Medical Sciences, Srinagar, Kashmir (India) from July 2001 to August 2006 were studied to evaluate and define the optimum treatment. RESULTS: Mortality in the surgically treated group of patients was 9.4% (12/119), while those treated non-surgically had a fatality rate of 16.66% (7/42). Multiple liver abscesses treated surgically had a surprisingly low mortality of 30%. The biliary tract (64.97%) was the most common cause of liver abscess. Multiple abscesses, mixed organisms and abscess complications are all associated with a significantly increased mortality. However, the lethality of the primary disease process was the most important factor in determining survival. CONCLUSION: Transperitoneal surgical drainage and antibiotics are the mainstay of treatment. Percutaneous drainage is recommended for high risk patients only.

Surgical management of complicated hydatid cysts of the liver.

AIM: To review the clinical presentation and surgical management of complicated hydatid cysts of the liver and to assess whether conservative surgery is adequate in the management of complicated hydatid cysts of liver. METHODS: The study was carried out at Sher-i-Kashmir Institute of Medical Science, Srinagar, Kashmir, India. Sixty nine patients with hydatid disease of the liver were surgically managed from April 2004 to October 2005 with a follow up period of three years. It included 27 men and 42 women with a median age of 35 years. An abdominal ultrasound, computed tomography and serology established diagnosis. Patients with jaundice and high suspicion of intrabiliary rupture were subjected to preoperative endoscopic retrograde cholangiography. Cysts with infection, rupture into the biliary tract and peritoneal cavity were categorized as complicated cysts. Eighteen patients (26%) had complicated cysts and formed the basis for this study. RESULTS: Common complications were infection (14%), intrabiliary rupture (9%) and intraperitoneal rupture (3%). All the patients with infected cysts presented with pain and fever. All the patients with intrabiliary rupture had jaundice, while only four with intrabiliary rupture had pain and only two had fever. Surgical procedures performed in complicated cysts were: infection-omentoplasty in three and external drainage in seven; intrabiliary rupture-omentoplasty in two and internal drainage in four patients. Two patients with intraperitoneal rupture underwent external drainage. There was no mortality. The postoperative morbidity was 50% in complicated cysts and 16% in uncomplicated cysts. CONCLUSION: Complicated hydatid cyst of the liver can be successfully managed surgically with good long term results.

Tubercular mastitis--a rare presentation.

Breast Tuberculosis is a rare form of tuberculosis even in tuberculosis endemic countries like India and its identity is often mistaken with breast cancer and pyogenic breast abscess. A 22-year-old married female, with history of child birth one month back, lactating, presented at peripheral hospital with progressively increasing pain and redness in the upper outer and central portion of her right breast. She was diagnosed as breast abscess and incisional drainage of abscess was carried out. However, patient's symptoms progressed and an ulcer began to appear on upper outer quadrant of her right breast which rapidly progressed to involve almost whole breast destroying nipple-areola complex. She was referred to our institution for further management. Debridement of the lesion was carried out and tissue sent for histopathological examination which revealed chronic granulomatous inflammation with caseating necrosis. Patient was put on anti-tubercular treatment for a period of six months. The whole ulcer healed up and she is doing well at present.

Conservative management of acute appendicitis.

BACKGROUND: The acute appendicitis is the most common abdominal emergency, and the primary treatment has been appendicectomy. Antibiotics are started preoperatively and continued postoperatively as needed. METHODS: This prospective study was carried out at Sher-i-Kashmir Institute of Medical Sciences, Soura, Srinagar, Kashmir, India to determine the role of antibiotics as the only treatment in acute appendicitis and the analgesic consumption needed. Total of 80 patients were included in the study with a duration of abdominal pain less than 72 h. Out of 80 patients, 40 patients received antibiotics intravenously for 2 days followed by oral treatment for 7 days, while another 40 patients considered as controls were randomized to surgery. RESULTS: Patients managed conservatively were discharged within 3 days except for two--patients who required surgery after 12 and 24 h, respectively, because of peritonitis due to perforated appendicitis. Four patients were readmitted within 1 year as a result of recurrent appendicitis and had to undergo surgery when appendicitis was confirmed. The diagnostic accuracy within the operated group was 90%. Two patients had perforated appendicitis at operation. CONCLUSION: Our conclusion is that antibiotic treatment in the patients with acute appendicitis is quite effective, and these patients may not need surgery. The patients managed conservatively with antibiotics alone experience less pain and require less analgesia but have high recurrent rate.

Delayed diagnosis of traumatic rupture of hydatid cyst of the liver--a case report.

We present a patient with slow rupture of hydatid cyst into the peritoneal cavity, presenting as massive abdominal distension and respiratory embarrassment. On paracentesis, no fluid could be drained. A small lateral incision was made under local anaesthesia to drain the 'ascites', but daughter cysts typical of hydatid came out. On laparotomy, there was a cyst in the right lobe of liver which had ruptured into the peritoneal cavity leading to secondary echinococcosis.
